Step 3The Board
Image 1: So, after you make TWO of those joule thief circuits, we can now make our board. Below is the configuration for my board, there is nothing special about it, I just tried to space the LEDs out across the perf board. All the LEDs labeled blue... are blue, and the rest are red.
Image 2: This will probably be the most helpful to you of any of the 3 pictures here. Again, the colors are not that important, just note the purple is (+) and green is (-). Also, to avoid confusion the blue LED circuit wires are a little lighter than the red LED circuit wires. The wires come off of the board so that you have (+) and (-) wires for your joule thief circuit 1 (red LEDs) and joule thief circuit 2 (blue LEDs). If you look at step 2 again you can see where purple and green wires connected to the (+) and (-) ends of the LED right? Well, since you made two of those joule thief setups with separate ferrite cores, transistors, etc. you will hook up one setup to the (+) and (-) of the red LED circuit and the other to the (+) and (-) of the blue LED circuit as seen in the diagram below. Hopefully, this makes sense.
Image 3: I guess I will show you the back of my board where I wired everything, but really don't pay attention to it because it looks HORRIBLE (yet amazingly it doesn't short if it gets shaken around a little). You will probably learn nothing from this picture except that I should never design major roadways. Make yours better than mine.
