Hey guys, check out my new blue moonlights. I only used 2 wide angle blue LEDs from radioshack. I was planning on using groups of LEDs, 1 blue and 2 white, but it made everything WAY too bright. I could use the white ones alone and it'd be a great daytime light. Anyway, here are the pics.
This is the closest to real thing I could get with my camera phone. It's actually darker than this.
I cranked up the ISO and got a much brighter pic, it's good for show, but it doesn't look like this.
Here are the brains behind the lights. I used 4 double A batteries, mounted externally (it was cheaper this way, and they're rechargeable). I used a variable voltage regulator, a potentiometer to set the voltage on the voltage regulator, and a couple capacitors. I found everything at radioshack. If I hadn't bought a bunch of extra LEDs, it would have cost me around $10. Since I bought the extra LEDs, I spend 25... I know, I could have done moonlighting cheaper, but I like DIY stuff.
Here's the TEMPORARY attachment of the project box to the my hood. Yeah it's duck tape.
Here's the fan that I attached to it to keep the voltage regulator's heatsink cool. I had this hangin around. It is rated for 12 V, but runs at 6V (albeit slower, which obviously makes sense).
Let me know what you think. I'll probably put one more LED in the middle, I just wanted to try it out with 2.
