**Building a Giant Perfection Game at Matter Hackers**

We had an exciting project at hand, building a giant perfection game at Matter Hackers, a community-driven workshop and makerspace. Our goal was to create a unique and engaging game that would challenge participants to test their skills and accuracy. We started by designing the marquee section of the game, which required us to hold it onto the front face and drive in screws from the backside. This ensured a sturdy foundation for our creation.

Once we had the basic structure in place, we moved on to mounting the game on the wall in the office. We carefully marked where the studs were and then drove in French cleats into those studs, securing the frame firmly in position. With the weight of the game distributed evenly, we felt confident that it would be stable and secure.

Before attaching the panels to the front of the game, we decided to take a few precautions to ensure easy removal and adjustment later on. We attached a face frame off until this point, as it was easier to move around without it. A couple of Brad nails held it in place, allowing us to make any necessary adjustments without having to disassemble the entire structure.

The next step involved adding the 3D-printed letters to the top section of the game. These letters were custom-made by the talented team at Matter Hackers and added a unique touch to our creation. With all the letters in place, we began testing the mechanisms of the game, ensuring that everything worked smoothly and as planned.

Unfortunately, we encountered an unexpected issue during testing. The solenoid was not designed to handle the force required to push the rack out, and no matter how many attempts we made, it simply wouldn't work. We tried different attachments and adjustments, but nothing seemed to solve the problem. After exhausting all possible solutions, we decided to abandon the automatic mechanism and instead opt for a manual solution.

The manual reset mechanism proved to be an excellent alternative, allowing us to play the game without relying on any mechanical parts. A rope system was incorporated into the design, which would allow players to hold the game in tension until they lost, at which point they could simply release the rope and let everything come crashing down. This solution not only solved our problem but also added an extra layer of excitement and challenge to the game.

As we continued to work on the project, we discovered another benefit to the manual mechanism – increased tension! We were able to double up the surgical tubing, which made the pieces fly out even farther and with greater force. This added a thrilling element to the game, making it more engaging and immersive for players.

After completing our giant perfection game, we were excited to introduce it to our new employees at Matter Hackers. The game was a huge success, with everyone having a blast playing and competing against each other. We renamed it "Extrusion" in honor of the team's love for 3D printing, and it quickly became one of the most popular attractions in the makerspace.

**Conclusion**

Our project at Matter Hackers was an incredible experience that taught us valuable lessons about problem-solving, creativity, and community engagement. Despite the setbacks and challenges we faced, we were able to adapt and innovate, resulting in a game that exceeded our expectations. We would like to extend our gratitude to the team at Matter Hackers for their support and expertise throughout this project.

"WEBVTTKind: captionsLanguage: enhey I'm Bob and I like to make stuff today we're gonna make a giant perfection game we were looking for a big game to build with our friends at mater hackers for their office and we decided on perfection this is a game where you have a bunch of different shaped pieces and you try to fit them into the corresponding hole before the timer runs out if you don't the pieces get shot out so we decided to build that for their office but really big and on a wall so we started out on the drawing board here and figured out some kind of general sizes and how the mechanism would work how big it needed to be and figured out all of the stuff before moving to the computer just worked out a 3d model of the entire thing so we knew how big everything was how much lumber we needed and how everything was going to work we also decided that the pieces needed to be 3d printed and some of the holes needed to be cut with the CNC so we sent those files off to the team at mater hackers well they worked on those we started working on the electronics prototypes electronics always look messy but there's really not a whole lot going on here I've got an Arduino Uno that I'm using for the brain of this but you could use pretty much any of them it doesn't need anything special I've also got two power supplies happening here for different reasons everything's run off 5 volts including the buttons and the LEDs and the Arduino but there's a 12 volt supply needed for the solenoid and this is the thing that actually gets triggered if you lose the game this will be explained more later on but since that's running off 12 volts and everything else is off 5 I had to figure out how to connect those two things together and for that I'm using a MOSFET now this is a piece that basically is a transistor that lets 5 volts trigger something of a higher voltage that's really all it's doing here if you're interested about that just do a quick search for the word MOSFET and you'll figure out all the details you need about it but on the 5 volt side of things we have the Arduino we have an arcade button which triggers the game and then we also have some limit switches these are going to be in each one of the holes that you press pieces into and when they all get pressed that means you win the game so that's all these pieces now I just have to move them from the temporary breadboard onto a permanent circuit board I've got everything moved to this board I've got connectors on the end of the wires and I've done as much as I can do here so now it's time to go to California Manor hackers is a really fantastic group of people and an awesome company they sell all sorts of 3d printers and materials for 3d printing and they make awesome projects like this insane nerf blaster they printed out all of the pieces for this game using flexible filament so it does Bend a little bit and it shouldn't hurt you in case it happens to hit you on the way out of the wall they printed all these different pieces out leaving holes on the inside of them so that you could put on a handle then they use their ex carbs to cut out the holes for these pieces in panels the same files from fusion 360 were used to 3d print the pieces and cut out the openings in these pieces of MDF we also wrote down all the measurements from that model so we could start ripping down the plywood to have all the right size pieces one of the challenges here is that we're using other people's tools but it's actually kind of cool too because it forces us to build this kind of large thing with pretty basic stuff that anybody can get their hands on we've got a portable table saw we're going to use a jigsaw circular saw and a sander I think that's about it later on this project is going to lean pretty heavily on 3d printing and C&C but as a general rule you can use the table saw like this to do a lot of the work that would also be done by a miter saw or a circular saw or a jig saw in this case we've been ripping all the pieces down to the long strips now we're going back and cutting them all to length if you have a crosscut sled that's the best way to do it but if you have this little miter gauge it'll work as well we've got just about all of the pieces cut I've got a few more to cut to size and then we're gonna paint everything before we put it together just gonna be easier to get the pieces painted before we start assembling stuff the top of the game has a couple of things on it that we're just going to replace with non functioning parts there's a timer that spins we're just gonna put a graphic there that looks like the timer there's also a toggle switch for on and off and instead of making a functioning one we're just going to glue together a couple of boards and cut a line and paint it to match I glued up these two pieces and went to clamp them together and realize that I only have three clamps it's kind of disappointing because I'm used to having so many more but you work with what you have each one of the pieces got prepared for use by putting a bolt through the hole in the center and then just screwing on a handle we also did a test fit of each piece within its panel a few of them did get trimmed a little bit to make sure that they fit tightly but not to tighten this is gonna be the big middle section where all the pieces go and we have to kind of plan ahead and figure out where to drill all the holes so that you have mechanisms that will come in from the back we have switches we have a lot of stuff to figure out so first we're gonna figure out where the different lines are where to drill the holes and so that we can actually put some pocket holes to join these two pieces of wood together regardless of what it might look like I don't really care for pocket holes anymore than anything else but in this situation they worked out really well we were working in someone else's shop with limited tools and it's a great way to join a bunch of different types of pieces basically we were just building a big cabinet here and it works really well for them this big center panel is just joined together from both sides with pocket hole screws now this doesn't mean it's not gonna flex in fact if you were to push on the center of it you could definitely break that apart luckily in this construction and that's never gonna happen we also put together a frame that's going to go on the outside of that big panel and that should help strengthen it quite a bit all right we're gonna paint the frame here but we don't need all of it painted because this is going to get glued and screwed to another piece later on so we're just gonna tape off kind of the inner inch of this entire frame before we paint it so we have some good surface to glue to later trying to pre assemble some of these pieces before we paint them just to save time so this one's actually gonna have to be assembled upside down it's just putting together pocket holes but we have to think ahead a couple of steps before we actually screw everything together to make sure we're doing it in the right order that's gonna be really big I love painting we finished up day 1 yesterday got pretty much everything painted and we're ready to come in this morning and I personally dropped the camera and I broke the lens so what you're looking at is a little bit different but that's why this one's kind of busted we assembled a bunch of the pieces yesterday and the next thing to put together is the rack now this racks purpose is to push all of the game pieces out of the game if you lose in the design process we talked about a bunch of different ways to do this because the original game is just a spring-loaded plate that pushes everything out but it's like this big we're working on something a lot bigger so we had to figure out a way to push a whole bunch of things out at one time so we talked about using a bunch of servos on each one of the holes we talked about using stepper motors to move a row at a time but I wanted to remove possibilities for errors and things that might break so we ended up with the whole rack that's gonna move at one time and push all the pieces out this is gonna be held in place by a little solenoid which I'll show you in a little bit and it's gonna have tension on it with surgical tubing and to make this rack we had to cut down a whole bunch of PVC you can use lots of different tools to cut PVC a small handheld pipe cutter works really well but we had to cut a whole bunch of pieces so we just used the saws that we had available since I was using the miter gauge here to push these pieces through I set up a stop block ahead of the blade if I was pushing these right up against the fence there's a good chance they would bind and go flying that would be bad this thing is gonna have a lot of flex to it because it's PVC but the bottom needs to be a little bit more rigid it's gonna be caught behind the solenoid and so it's gonna have all the pressure that's gonna be pulling this thing forward narrow down to one point on the bottom row so we're gonna put a piece of metal conduit on the inside of that pipe just to reinforce it hopefully strengthen the whole thing up a little bit now this was kind of a gamble using something that's flexible like this it is very bendy but I think we're gonna reinforce more of it with conduit and really it doesn't have to do a whole lot each one of these points for these T's just has to push out a small piece and those pieces don't fit in super tightly so I think it's gonna work out last time I was here at mater hackers we made a foosball table and I'll put a link to that so you can check it out but we had some leftover conduit from that so we're gonna drop these shorter pieces down into the sides to reinforce this rack to finish up the main big panel in the center we needed to add that black trim around the big blue square it needed to overhang one inch on each side so we cut some spacers to put on the two corners that way we could lay the frame on from the backside and not have to worry about trying to get it even this guy glue all the way around and several screws to tie these two things together to tie this panel into the main frame we also use some spacers from the front edge we clamp those on lay this panel up against it and drove in the screws from the back side this makes sure that the panel is the same distance from the front edge on both sides and gives you something to push against when you're driving in the screws well I think it's big cool it's very orange so the next step we got about the rack on the back side of this and figure out where all of the little things are gonna intersect and then cut some holes so that they can come through so the top row of this rack is going to be pivoting within these little aluminum tubes and this was just a tube that I had are in my shop and we cut some short pieces this is going to go in right here and so for this to go in we have to drill a one-inch hole but not all the way through the material so we're gonna go in just the right depth slide this in and then slide it in the PVC whoo that's nice sweet yeah man measure data grid where the center points of each one of these panels was going to be and drilled a small pilot hole I cut a block of wood the size of the opening that I wanted and drilled a hole right in the center they used the drill bit to mount that within my pilot hole and then trace the outside after that we mounted the rack up into the top bar and made sure that each one of the arms touched in the center of that square that I had drawn then I decided that it might be cleaner to cut these out from the front so we traced the same square on the front face and then drilled some pilot holes in the corner I used a jig saw to connect those holes this didn't give me the cleanest cut out but overall it worked pretty well all right now we got to make sure all the pieces come through they do it did work look at that so we've got the whole rack in there and it moves freely it comes through the front of the board which is fantastic the next thing is to mount the solenoid so that the whole rack will come back and get locked in place now unfortunately the size of this doesn't really work super well back there so we need to put a flat edge on the bottom of the PVC so that it will get locked in place until we release this so we're just gonna cut a piece of wood screw it up into the PVC pipe after we got that little bracket mounted to the bottom of the pipe we attached the solenoid to a long piece of one by four this got pocket holed into the outside frame so we could move it up and down to get it in the right position we had to adjust the height a little bit but eventually we got it to catch on the solenoid and after that we added a couple more of these cross braces just to support the entire thing we are in the final day of this bill this is day three that we're starting out I just put on these two cleats and these are really here to have a spacer that goes up to this front board from the front of the game you're gonna be pushing on a lot and this big panel tends to flex a little bit so these are just going to help keep it in place now we have one more of these to put into place and this is gonna be all the way up at the top I made a little French cleat here and this is going to get mounted up inside the frame and then the other one to the wall and that will keep the top of this entire gigantic thing attached to the wall for safety the next thing is to get this rack under tension so that it will always try to pull itself forward and push the pieces out to do that we're going to wrap surgical tubing around it and then the other end of the tubing will go around an eyelet that will be all the way down here at the bottom on the front edge for now we're just going to do some testing here and so I'm just tying the stuff in or not it's got enough friction against itself that that actually kind of works so we may not have to go back and zip tie it together but we may we'll see it works that's pretty awesome now we're at a point we're ready to put in the electronics and all the stuff that I made back in my shop now I have to figure out how to actually fit into this giant machine the good thing is I think we have everything we need we're just going to have to splice some of the LEDs so we have two strips put in some pieces get everything mounted but I think we're good to go got to go looking for the tools that I need in their lab all right so I've got a little port here on the top that we're just gonna feed these wires up through so all the electronics can actually be behind this whole thing and then we're going to use some CA glue just to hold these leds up against this front edge there's gonna be a face frame that's gonna wrap over this and so if we get them all the way forward they'll be hidden a little bit better we're only going to be putting LEDs on the two sides not all the way around and so I cut off the strip down here at the bottom usually these strips have a place where you can trim them and it has exposed terminals so you can put an extension wire to connect another terminal later on so I cut it down here soldered on a three conductor wire that we're gonna feed through behind the whole machine and then back out to connect to the strip on that side we're gonna put on this marquee frame and it's three inches from the outside edge so I just made a little spacer that's three inches so I'm going to kind of take it around and just use it to place all of these pieces really quickly so this entire game only has one button we're gonna have one of these arcade buttons that you hit to start the game and then when you have all the pieces in place you go back and hit it again to stop the timer stop everything from exploding we wanted to put the button up here which is pretty high and so we wouldn't ask the shortest person in the office if they could reach that they okay that so we're gonna put it up there I love it when a plan comes together so I made this little wiring harness like I showed you earlier back in the shop and I made the wire for the button just about the perfect length I intentionally made all these things with connectors on the end of them so that we could just kind of snap everything in all the power will go into these all of these pins will drop right into the pins of the Arduino so it should be pretty easy to hook this whole thing up okay and not quite as smart as I thought I was this one that I thought was for the button is actually for the solenoid at the bottom I ended up having to make a few extension wires and modify the code just a little bit on site but I got it working we replace the wooden catch that touched the solenoid with a 3d printed one then it was time to build in the reset mechanism for the whole rack the idea was to have a handle on the outside of the frame and when you pull that handle it would draw the rack back and lock it into the solenoid we screwed in two eyelets on the inside of the box and then fed a paracord from the center of the rack up through those eyelets and out a hole in the side of the frame we've got the rack under tension which is a good thing so now it slams forward to push the pieces out but it also slams into the wood which is going to be a bad thing for wear and tear so we cut some small pieces of EBA foam we use some hot glue and just stick them right where the PVC contacts the wood to help soften the blue we also mounted some of the elements on the marquee section by holding them onto the front face and driving in some screws from the backside then it was time to start mounting this thing on the wall in the office we marked where the studs were and then drove in the French cleat into those studs we've got it moved into the space and it's ready to hang on the wall but we wanted to move it before we put on all these panels just keep the weight down so now we're gonna attach the panels to the front of this with some Brad nails so just in case they need to take them off and adjust them later they can turn each one of these panels had a one inch border around it so I cut some one inch spacers to use to mount these it made it a lot faster rather than having to measure out a full grid and make sure all the pieces were centered the spacers made it go really quick we left the face frame off until this point just because it was easier to move around without the face frame there a couple of Brad nails held it in place that way in case they needed to get to the LEDs to change anything in the future this could pop right off then it was time to put all of the text on the top section all of these letters were 3d printed by the people at Mater hackers it was just a matter of getting them laid out and glued on and after all the letters were in place it was finally time to start testing the pieces and make sure all of our mechanisms work so for the past couple hours we've been testing this thing and unfortunately we hit a roadblock that we don't really have time to get around we had a plan for how this whole thing was gonna work coming into it only being here for three days to build it and we've pretty much run out of time so here was the plan so the whole idea was that the rack would be pulled back over the solenoid and get locked in here and then when you applied power that would draw down releasing the whole rack and everything would go forward unfortunately there's too much force going this direction and the solenoid is just made to pull this direction so we got a bigger one this was 12 volts we went up to one that was 24 volts we tried a bunch of different attachments on the top of it it has the same problem even if we had gotten that to work we couldn't have put a whole lot of pressure on it which means we couldn't have probably pushed all the pieces out so we're gonna abandon this idea now we do have a manual way around it which is really good the whole reset mechanism here with the rope somebody can hold it in tension to play the game and then if the person loses they can just let go of the rope and it will all happen knock all the pieces out everything will be good it's just not gonna be automatic like we had planned unfortunately that's just kind of what happens when you build in another place if you don't have all your tools and you don't have all the time you want to solve all the problems but the good thing is you'll still be able to play the game a couple other things that are good about it though is that it allows us to put more tension on this so now we got to double up the surgical tubing it's gonna fly forward even harder push the pieces out even better and all of this is gonna stay here at mater hackers so if they can find a good way to do it find the parts they need they can totally swap out that mechanism and make it work so there it was all finished and ready to bring in some employees to test it out here it is our giant perfection game that we renamed extrusion because we're at mater hackers and they are all about getting people 3d printing if you need any materials or machines just give them a call because they're an awesome group of people and they just want to help now this project turned out really great it's not quite exactly like we were hoping there's a couple things we had to leave out just because we're under a time constraint but it is totally playable it's a lot of fun and it is gigantic it was a ton of fun big thanks to matter hackers for having us out here to build this and add to our collection of I like to make stuff games here in their office if you want to see the foosball table that we did for them a long time ago it'll be linked right there I've also got some other videos you may want to check out and if you're not subscribed go ahead and do that right there that's it for this one guys thanks for watching I'll see you next time so later on this project is gonna take pretty his take okay now I just have to move this stuff from a temporary breadboard onto a permanent circuit board circle circle board circle circle boardhey I'm Bob and I like to make stuff today we're gonna make a giant perfection game we were looking for a big game to build with our friends at mater hackers for their office and we decided on perfection this is a game where you have a bunch of different shaped pieces and you try to fit them into the corresponding hole before the timer runs out if you don't the pieces get shot out so we decided to build that for their office but really big and on a wall so we started out on the drawing board here and figured

and then we also have some limit switches these are going to be in each one of the holes that you press pieces into and when they all get pressed that means you win the game so that's all these pieces now I just have to move them from the temporary breadboard onto a permanent circuit board I've got everything moved to this board I've got connectors on the end of the wires and I've done as much as I can do here so now it's time to go to California Manor hackers is a really fantastic group of people and an awesome company they sell all sorts of 3d printers and materials for 3d printing and they make awesome projects like this insane nerf blaster they printed out all of the pieces for this game using flexible filament so it does Bend a little bit and it shouldn't hurt you in case it happens to hit you on the way out of the wall they printed all these different pieces out leaving holes on the inside of them so that you could put on a handle then they use their ex carbs to cut out the holes for these pieces in panels the same files from fusion 360 were used to 3d print the pieces and cut out the openings in these pieces of MDF we also wrote down all the measurements from that model

to build this kind of large thing with pretty basic stuff that anybody can get their hands on we've got a portable table saw we're going to use a jigsaw circular saw and a sander I think that's about

way to do it but if you have this little miter gauge it'll work as well we've got just about all of the pieces cut I've got a few more to cut to size and then we're gonna paint everything before we put it together just gonna be easier to get the pieces painted before we start assembling stuff the top of the game has a couple of things on it that we're just going to replace with non functioning parts there's a timer that spins we're just gonna put a graphic there that looks like the timer there's also a toggle switch for on and off and instead of making a functioning one we're just going to glue together a couple of boards and cut a line and paint it to match I glued up these two pieces and went to clamp them together and realize that I only have three clamps it's kind of disappointing because I'm used to having so many more but you work with what you have each one of the pieces got prepared for use by putting a bolt through the hole in the center and then just screwing on a handle we also did a test fit of each piece within its panel a few of them did get trimmed a little bit to make sure that they fit tightly but not to tighten this is gonna be the big middle section where all the pieces go and we have to kind of plan ahead and figure out where to drill all the holes so that you have mechanisms that will come in from the back we have switches we have a lot of stuff to figure out so first we're gonna figure out where the different lines are where to drill the holes and so that we can actually put some pocket holes to join these two pieces of wood together regardless of what it might look like I don't really care for pocket holes anymore than anything else but in this situation they worked out really well we were working in someone else's shop with limited tools and it's a great way to join a bunch of different types of pieces basically we were just building a big cabinet here and it works really well for them this big center panel is just joined together from both sides with pocket hole screws now this doesn't mean it's not gonna flex in fact if you were to push on the center of it you could definitely break that apart luckily in this construction and that's never gonna happen we also put together a frame that's going to go on the outside of that big panel and that should help strengthen it quite a bit all right we're gonna paint the frame here but we don't need all of it painted because this is going to get glued and screwed to another piece later on so we're just gonna tape off kind of the inner inch of this entire frame before we paint it so we have some good surface to glue to later trying to pre assemble some of these pieces before we paint them just to save time so this one's actually gonna have to be assembled upside down it's just putting together pocket holes but we have to think ahead a couple of steps before we actually screw everything together to make sure we're doing it in the right order that's gonna be really big I love painting we finished up day 1 yesterday got pretty much everything painted and we're ready to come in this morning and I personally dropped the camera and I broke the lens so what you're looking at is a little bit different but that's why this one's kind of busted we assembled a bunch of the pieces yesterday and the next thing to put together is the rack now this racks purpose is to push all of the game pieces out of the game if you lose in the design process we talked about a bunch of different ways to do this because the original game is just a spring-loaded plate that pushes everything out

the holes we talked about using stepper motors to move a row at a time but I wanted to remove possibilities for errors and things that might break so we ended up with the whole rack that's gonna move at one time and push all the pieces out this is gonna be held in place by a little solenoid which I'll show you in a little bit and it's gonna have tension on it with surgical tubing and to make this rack we had to cut down a whole bunch of PVC you can use lots of different tools to cut PVC a small handheld pipe cutter works really well but we had to cut a whole bunch of pieces so we just used the saws that we had available since I was using the miter gauge here to push these pieces through I set up a stop block ahead of the blade if I was pushing these right up against the fence there's a good

reinforce more of it with conduit and really it doesn't have to do a whole lot each one of these points for these T's just has to push out a small piece and those pieces don't fit in super tightly so I think it's gonna work out last time I was here at mater hackers we made a foosball table and I'll put a link to that so you can check it out but we had some leftover conduit from that so we're gonna drop these shorter pieces down into the sides to reinforce this rack to finish up the main big panel in the center we needed to add that black trim around the big blue square it needed to overhang one inch on each side so we cut some spacers to put on the two corners that way we could lay the frame on from the backside and not have to worry about trying to get it even this guy glue all the way around and several screws to tie these two things together to tie this panel into the main frame we also use some spacers from the front edge we clamp those on lay this panel up against it and drove in the screws from the back side this makes sure that the panel is the same distance from the front edge on both sides and gives you something to push against when you're driving in the screws well I think it's big cool it's very orange so the next step we got about the rack on the back side of this and figure out where all of the little things are gonna intersect and then cut some holes so that they can come through so the top row of this rack is going to be pivoting within these little aluminum tubes and this was just a tube that I had are in my shop and we cut some short pieces this is going to go in right here and so for this to go in we have to drill a one-inch hole but not all the way through the material so we're gonna go in just the right depth slide this in and then slide it in the PVC whoo that's nice sweet yeah man measure data grid where the center points of each one of these panels was going to be and drilled a small pilot hole I cut a block of wood the size of the opening that I wanted and drilled a hole right in the center they used the drill bit to mount that within my pilot hole and then trace the outside after that we mounted the rack up into the top bar and made sure that each one of the arms touched in the center of that square that I had drawn then I decided that it might be cleaner to cut these out from the front so we traced the same square on the front face and then drilled some pilot holes in the corner I used a jig saw to connect those holes this didn't give me the cleanest cut out but overall it worked pretty well all right now we got to make sure all the pieces come through they do it did work look at that so we've got the whole rack in there and it moves freely it comes through the front of the board which is fantastic the next thing is to mount the solenoid so that the whole rack will come back and get locked in place now unfortunately the size of this doesn't really work super well back there so we need to put a flat edge on the bottom of the PVC so that it will get locked in place until we release this so we're just gonna cut a piece of wood screw it up into the PVC pipe after we got that little bracket mounted to the bottom of the pipe we attached the solenoid to a long piece of one by four this got pocket holed into the outside frame so we could move it up and down to get it in the right position we had to adjust the height a little bit but eventually we got it to catch on the solenoid and after that we added a couple more of these cross braces just to support the entire thing we are in the final day of this bill this is day three that we're starting out I just put on these two cleats and these are really here to have a spacer that goes up to this front board from the front of the game you're gonna be pushing on a lot and this big panel tends to flex a little bit so these are just going to help keep it in place now we have one more of these to put into place and this is gonna be all the way up at the top I made a little French cleat here and this is going to get mounted up inside the frame and then the other one to the wall and that will keep the top of this entire gigantic thing attached to the wall for safety the next thing is to get this rack under tension so that it will always try to pull itself forward and push the pieces out to do that we're going to wrap surgical tubing around it and then the other end of the tubing will go around an eyelet that will be all the way down here at the bottom on the front edge for now we're just going to do some testing here and so I'm just tying the stuff in or not it's got enough friction against itself that that actually kind of works so we may not have to go back and zip tie it together but we may we'll see it works that's pretty awesome now we're at a point we're ready to put in the electronics and all the stuff that I made back in my shop now I have to figure out how to actually fit into this giant machine the good thing is I think we have everything we need we're just going to have to splice some of the LEDs so we have two strips put in some pieces get everything mounted but I think we're good to go got to go looking for the tools that I need in their lab all right so I've got a little port here on the top that we're just gonna feed these wires up through so all the electronics can actually be behind this whole thing and then we're going to use some CA glue just to hold these leds up against this front edge there's gonna be a face frame that's gonna wrap over this and so if we get them all the way forward they'll be hidden a little bit better we're only going to be putting LEDs on the two sides not all the way around and so I cut off the strip down here at the bottom usually these strips have a place where you can trim them and it has exposed terminals so you can put an extension wire to connect another terminal later on so I cut it down here soldered on a three conductor wire that we're gonna feed through behind the whole machine and then back out to connect to the strip on that side we're gonna put on this marquee frame and it's three inches from the outside edge so I just made a little spacer that's three inches so I'm going to kind of take it around and just use it to place all of these pieces really quickly so this entire game only has one button we're gonna have one of these arcade buttons that you hit to start the game and then when you have all the pieces in place you go back and hit it again to stop the timer stop everything from exploding we wanted to put the button up here which is pretty high and so we wouldn't ask the shortest person in the office if they could reach that they okay that so we're gonna put it up there I love it when a plan comes together so I made this little wiring harness like I showed you earlier back in the shop and I made the wire for the button just about the perfect length I intentionally made all these things with connectors on the end of them so that we could just kind of snap everything in all the power will go into these all of these pins will drop right into the pins of the Arduino so it should be pretty easy to hook this whole thing up okay and not quite as smart as I thought I was this one that I thought was for the button is actually for the solenoid at the bottom I ended up having to make a few extension wires and modify the code just a little bit on site but I got it working we replace the wooden catch that touched the solenoid with a 3d printed one then it was time to build in the reset mechanism for the whole rack the idea was to have a handle on the outside of the frame and when you pull that handle it would draw the rack back and lock it into the solenoid we screwed in two eyelets on the inside of the box and then fed a paracord from the center of the rack up through those eyelets and out a hole in the side of the frame we've got the rack under tension which is a good thing so now it slams forward to push the pieces out but it also slams into the wood which is going to be a bad thing for wear and tear so we cut some small pieces of EBA foam we use some hot glue and just stick them right where the PVC contacts the wood to help soften the blue we also mounted some of the elements on the marquee section by holding them onto the front face and driving in some screws from the backside then it was time to start mounting this thing on the wall in the office we marked where the studs were and then drove in the French cleat into those studs we've got it moved into the space and it's ready to hang on the wall but we wanted to move it before we put on all these panels just keep the weight down so now we're gonna attach the panels to the front of this with some Brad nails so just in case they need to take them off and adjust them later they can turn each one of these panels had a one inch border around it so I cut some one inch spacers to use to mount these it made it a lot faster rather than having to measure out a full grid and make sure all the pieces were centered the spacers made it go really quick we left the face frame off until this point just because it was easier to move around without the face frame there a couple of Brad nails held it in place that way in case they needed to get to the LEDs to change anything in the future this could pop right off then it was time to put all of the text on the top section all of these letters were 3d printed by the people at Mater hackers it was just a matter of getting them laid out and glued on and after all the letters were in place it was finally time to start testing the pieces and make sure all of our mechanisms work so for the past couple hours we've been testing this thing and unfortunately we hit a roadblock that we don't really have time to get around we had a plan for how this whole thing was gonna work coming into it only being here for three days to build it and we've pretty much run out of time so here was the plan so the whole idea was that the rack would be pulled back over the solenoid and get locked in here and then when you applied power that would draw down releasing the whole rack and everything would go forward unfortunately there's too much force going this direction and the solenoid is just made to pull this direction so we got a bigger one this was 12 volts we went up to one that was 24 volts we tried a bunch of different attachments on the top of it it has the same problem even if we had gotten that to work we couldn't have put a whole lot of pressure on it which means we couldn't have probably pushed all the pieces out so we're gonna abandon this idea now we do have a manual way around it which is really good the whole reset mechanism here with the rope somebody can hold it in tension to play the game and then if the person loses they can just let go of the rope and it will all happen knock all the pieces out everything will be good it's just not gonna be automatic like we had planned unfortunately that's just kind of what happens when you build in another place if you don't have all your tools and you don't have all the time you want to solve all the problems but the good thing is you'll still be able to play the game a couple other things that are good about it though is that it allows us to put more tension on this so now we got to double up the surgical tubing it's gonna fly forward even harder push the pieces out even better and all of this is gonna stay here at mater hackers so if they can find a good way to do it find the parts they need they can totally swap out that mechanism and make it work so there it was all finished and ready to bring in some employees to test it out here it is our giant perfection game that we renamed extrusion because we're at mater hackers and they are all about getting people 3d printing if you need any materials or machines just give them a call because they're an awesome group of people and they just want to help now this project turned out really great it's not quite exactly like we were hoping there's a couple things we had to leave out just because we're under a time constraint but it is totally playable it's a lot of fun and it is gigantic it was a ton of fun big thanks to matter hackers for having us out here to build this and add to our collection of I like to make stuff games here in their office if you want to see the foosball table that we did for them a long time ago it'll be linked right there I've also got some other videos you may want to check out and if you're not subscribed go ahead and do that right there that's it for this one guys thanks for watching I'll see you next time so later on this project is gonna take pretty his take okay now I just have to move this stuff from a temporary breadboard onto a permanent circuit board circle circle board circle circle board\n"
