RobG 1,892 Posted August 31, 2013 Share Posted August 31, 2013 3 channel, high power LED driver, built to fit 10W RGB LEDs (those things are blindingly bright!) Now on Tindie. spirilis, PTB, GeekDoc and 1 other 4 Quote Link to post Share on other sites
oliver81 0 Posted September 26, 2013 Share Posted September 26, 2013 This is very bright and we get three different colors from the LEDs and with such brightness. Can you please explain the working of this circuit i.e. how would you manage to get three different lights from the single output and what sort of multiplexing device you use? Moreover, Can you please tell me the input power requirement of this circuit? pcb quote Quote Link to post Share on other sites
RobG 1,892 Posted September 26, 2013 Author Share Posted September 26, 2013 The board is powered from 12V/1A source. There are 3 inputs, one for each color. You can control brightness using two methods, DC (voltage between 0.5V and 2.5V (0%-100%) and PWM In my video, I am using PWM. Quote Link to post Share on other sites

RobG 1,892 Posted October 30, 2013 Author Share Posted October 30, 2013 Here's a different version of the 3ch constant current driver. It can deliver up to 1.2A per channel. PWM input for brightness control. Current can be selected using 3 jumpers, each channel separately, 7 possible values (for example 1A, 0.8A, 0.7A, 0.5A, 0.3A, and 0.2A.)

spirilis 1,265 Posted January 22, 2014 Share Posted January 22, 2014 Curious- what's your final project for these? Pretty cool powah Sent from my Galaxy Note II with Tapatalk 4 Quote Link to post Share on other sites
RobG 1,892 Posted January 22, 2014 Author Share Posted January 22, 2014 I will use those as flood lights to light up my house, Halloween, Xmas, St. Patty, July 4th, etc. (think Empire State building, but on a smaller scale and animated.) There will be 10-15 of them, 10W & 20W, covering the entire front of my house. spirilis and GeekDoc 2 Quote Link to post Share on other sites
RobG 1,892 Posted April 9, 2014 Author Share Posted April 9, 2014 New board, 4 channel this time. The board can be cut into single channel drivers. Available on Tindie. Quote Link to post Share on other sites
RobG 1,892 Posted December 21, 2014 Author Share Posted December 21, 2014 Since I made all those floods, I figured I will need something to control them, and here it is, DMX - 8 RGB flood controller. MSP430G2553 is used to receive DMX and control TLC5947. Quote Link to post Share on other sites
