Rainbow LED Panel by suricata5 Rainbow LED Panel by suricata5
A rainbow LED panel I constructed while camping with my parents. Took about 2-3 hours. I was so happy to finally get my hands on a true violet LED, which is a pretty new technology.

Surprisingly the violet LED required less voltage than the blue, which had the highest voltage rating.

Violet needed a resistor? I wouldn't have thought that. Nice I might make one.

Have you checked out the rest of my gallery? I have lots of lightpainting pics made with this.

nice dude i didn't know that the violet led can tolerate 6V's

Nicely done. I used to be pretty good at electronics but I reckon I'd make it explode if I was to try now ^^;

Great piece of kit for some inventive pictures though :) Well done.

thanks! yeah, the voltage requirements (and hence resistor needs) are different for each color, increasingly higher as you approach violet. I had fun with it.

:dygel: I took an electronics class once. I wish I remembered more than the resistor colors.

Well, all my learning is mostly self-taught. I have an awesome book called \"Robot Building for Beginners\" by David Cook. I spend a lot of time on solarbotics.org, building kits, and just experimenting. There are lots of hobbyists out there willing to share their knowledge - you don\'t need any formal classes to build cool electronic circuits.

This LED panel was very simple - just a matter of figuring out how much resistance was needed for each LED. They require more voltage as you go from red to violet. Red only needs about 1.5 V, but blue needs 5.5 and the violet can tolerate 6! The violet was challenging - I originally had it so bright it appeared white, so I experimented with different resistor values until I reduced it down its pinker value. My soldering here is pretty messy, but I was camping with limited supplies and hurrying in the middle of the night - it didn\'t need to be fancy anyway since its only purpose is light painting in the dark.

:) Thanks for the advice! That's cool with the violet LED.

Hmmm that looks like it was probably hard to make but I kind of want one

I have some experience building small robots as a hobby - this wasn't too bad
