Make you own wearable arc reactor and be cooler than Tony Stark!

Step 6 Electronics!

Now there are several ways to light your arc reactor and you should do it however you want. I started with 3 leds but miscalculated and ended with one. in fact i like this new effect better.

Since i have one led with .02 a and i have a battery pack (6v) and the led takes 3.2-3.8 v...
so... i need a resistor.

my voltage drop is 2.5 volts ( now my led will run at 3.5 volts which is ok)
so i divide that by .02a and i get the number 125!

now i have a 120 ohm resistor horay!


1. cut your perf board so it just barely snaps into the threads of the cap.

2.put you led as centered as you can on your perf board.

3. Put your resistor in the perf board.

4. solder your resistor to a short piece of wire (resistors have no polarity so don't worry). solder the other end to the anode (long leg) of your led.

5. solder the other leg (cathode) of your led to a short piece of wire.

6. test with 6 volts.


Yay it works!!

sorry the pics are a little sparce but the third one is similar but it has 3 led and a different resistor.
