4 times the fun. I need a cheep source of these SMD RGB LEDs. I don't feel like buying a full reel yet.

SMD RGB LED - failure mode

They don't like the heat and just die. OK might have guessed something like that. BUT they also suck in flux with all the dirt and just short out! WTF !! Now that I've killed 5 of these, I can only run one of the boards. I need to get more for replacement.

Trying to figure out the right resistor values. For 5V: R: 1.75V -- 100Ω G: 2.55V -- 90Ω B: 2.60V -- 110Ω

RGB LED Ring - 2nd prototype

I got 4 boards from BatchPCB again, only this time 2 of them had broken traces. Fortunately they can be fixed as shown. This revision now supports auto reset and has a smaller spacing between the pads for the solder bridges. The next one will come with jumpers.

The next round in my prototyping game. I declare this board as the final version, more or less ;-) Design files, code and documentation .

V2.0.c front

Yesterday I saw a light bulb with PLCC2 LEDs. They were 'speaking to me' ;-) So I just added a 'dual footprint' to the board. If you only need one color, just use PLCC2 LEDS and only populate one LED driver chip.

RGB LED Ring - Real PCBs

I finally got the PCBs from sparfun. It almost took 6 weeks. 9 days for the letter to get to me. I wonder what takes so much time for "air mail". Must have been my "dear friends" at the customs office again. Unfortunately this is _not_ the updated design I sent them shortly after I had placed my order, so this PCB version doesn't support auto-reset :-( Let's hope the rest works.

Edit: Works great and will go on my BIKE! 100% illegal taillights ;-)

RGB LED Ring - A BatchPCB test

Top side. This is revision 1.21 It is now equipped with an optional (jumper) ultra low drop voltage regulator and can run from either regulated 5V DC or from up to 14V DC (no spikes please). The input voltage is limited by the regulator's decoupling caps. I could only get 16V tantalum types in 1206. It also now supports auto-reset for even easier code updating. With the onboard regulator it can conveniently be powered by say a 9V block or 4 AA batteries.
