It's Almost Christmas and I Don't Have a Christmas Tree Yet...
But an ordinary one is kind of boring for an electronic enthusiast, so I sat down and created my own miniature LED Christmas tree. It turned out to be a nice decoration, and I'm going to show you the easy steps to build your own.
What Did I Used for This Tree?
Well, not much exactly - most importantly it needs time and patience on the material side. We have a small PCB for mounting the root of the tree and giving the whole construction stability. Then of course, we have the LEDs that I use, defused green ones with a forward voltage of 3.2 volts.
The Most Important Material for Creating a Structure is Bridge Wire
Basically just Cooper wire which is silvered. And lots and lots of solder. Step 1: creating a lot of straight strings of the wire. I use to apply us to grip the wire and stretch it, so you should get really nice straight wire this way.
And we're gonna need a lot of it. Step 2: I did not have a PCB with the right size, so I used this old one where only one half is used just going to use my cutter to engrave a line and then use an edge to break the PCB apart.
Step 3: I soldered for Cooper wires which are 40 centimeters long to the PCB. Which will represent the root of the tree. Two of them will be the 5 volt array of the tree, and the other one will be to the ground rail. And I also added those plastic feeds to give the PCB more grip on the surface.
Step 4: Bending the wires to circles. I basically had four different sized wires for the circles - 40 centimeter, 30 centimeter, 20 centimeter, and obviously 10 centimeter. And I am slowly bending those wires by hand and soldered the ends together, which really requires patience because it has to look somehow like a circle in the end.
And even with all my goddamn patience, sometimes it looks well not nice. Those will be the positive circles which will have the 5 volt potential later. You thought you were done with bending round? Wrong.
Step 5: Bending the ground circles. The LEDs will later sit in between those two. So the ground circle has to be slightly smaller. I subtracted 2 centimeters from each circle and Bend rings again okay.
Step 6: Time to solder the LEDs to the Rings
The positive side goes to the bigger circle, and the negative side to the smaller one. I used 8 LEDs for the two biggest circle pairs and then 4 LEDs for the two smallest ones. And always test your circles during the bullet - you don't want to replace an LED when the tree is complete but only use 3 point 2 volts when you don't want to use a resistor in serious.
Step 7: Now it's Assembly Time
I used 9-volt batteries as spacers and juice bridge wire again to connect the circles to the root. Positive circle connects to the 5 volt strings, and negative circle connects to the ground strings. Remember this wire is conductive in every point - that means I have to look out that 5 volts and ground potential never touch at any point that would equal a short-circuit, and the LEDs will not light up.
And at the end, I put a single LED on top between the 5 volts and ground root. Because we can't use 5 volts for 3.2 volt LEDs - a resistor is necessary. The tree draws 204 milliamps at 3 point 2 volts, which means we have to divide 1.8 volts by 0.2 4 amps which equals around 8.8 ohms.
And the power of 0.3 7 watts I bought this one Watts 10 ohm resistor and just soldered it in seriously to the 5 volt rail now. It works for 5 volts and even USB power.
I Wish You a Merry Christmas and Happy Holidays, and I will see you next time!
