The one shown in the link is o.k. for powerRGB. I bought mine via Ebay from a Seller in China.

Hello Tobi,

which RGB LED you’ve used and where you bought the led? the only RGB LED I find here is the http://www.led1.de/shop/product_info.php?pName=prolight-power-rgb-led-3-watt-ga-p-308&cName=prolight-power-leds-prolight-power-rgb-leds-c-8_73

I had problems with some MOSFET’s and with the resistors it worked well…
Leave at least the series resistor (r1-r3) to limit gate charge currents.

Why you have those R4 to R6 + Vcc connections? This would work better without them.

Hi,
any N-Channel, Enhancement, Logic level MOSFET should be o.k. You should also select some with low Rds_on. For the STORM hack I used some IRL3103 ( http://www.irf.com/product-info/datasheets/data/irl3103.pdf ).

Hope that helps… Tobi

Can you provide some part # for the MOSFET that will work with powerRGB? I’m not all that familiar with them, and a stab at Digikey’s search function didn’t return anything useful. Thanks.

BTW, I find this a much simpler circuit than others I’ve seen, and I like the extensibility to cover higher power RGB. Thanks for posting!
