Does anyone have a circuit or know of any links, I want to build my own constant current drivers for this project for the 3wRGB's. I know of several key components to possibly use, such as LM317's with 1 uf capacitor for helping with blending, or use TLC5940 with Mosfet (logic level) P...

Yes, I can't thank Eddy enough... great support! I want to build my own drivers for these using NPN resistors, Mosfets are a few of the buzz words I've been hearing. I'll post back my experiences, the prices dropped on the 3W RGBSs and Tech hardware is getting better so I know I can make these...

ah, I'm learning and determined...Thankyou all for being so helpful !

it actually looks like an omission from the seller, I found an identical RBG on dealextreme with this explanation (self evident, but stated clearly)... Note: each color channel is able to take a maximum of 350mA of current, thus a 1050mA combined current input and the 3W rating. [/size]...

Yes, I understand those specs, but, do all 3w RGB 4pin function the same? if the seller list max=350ma and another seller has what appears to be the same start but listed as 350ma-1000ma...are these the same and it's simply an omission by the seller, or, does the physical design of the RGB...

Thanks for the heads up on those, can't trust any of these specs ! I noticed some of the 3w RGB only list max at 350ma, whiles other will have 350ma-1000ma, why would this be? The only way it could reach 1000ma if is all three chips sets are on blending, is this correct, where as the...

If those will work for the drivers, would this work for the DMX controller, if so how would my wiring go from driver to dmx module...

I'd definitely use 12v, but, could see using 24v if daisy chaining eventually. how about these off ebay http://www.ebay.com/itm/2pcs-3W-RGB-LED-Driver-Transformer-DC12V-24V-for-3W-RGB-LED-Light-/370743785626?pt=LH_DefaultDomain_0&hash=item56520d389a use 1 per RGB star so I'd get 6, I...

Re: 3w RGB star / RGB controllers how many constant current drivers would I need for a 6 star RGB bar? one for each RGB led, then 6. Any recommendations for drivers.... would it need to be 350a or 1050a

Thankyou, ok, SMD strips = series leds, 3w Star = parallel leds. So the mini 3ch controller is simply not made to manage current but rather voltage more less on the strip leds. But, if I manage the dissipation it's possible I could use either controller or holidaycoro's dmx driver. I really...

Ah, ... I'm starting to understand I think. The mini 3 channel dmx controller I found is with (mainly) for the LED strip lighing like 5050 SMD's something like the 150/300 chip strips, which case are really dumb strips and just run preprogramed modes. So, these SMD's leds are very different...

darnit, ok...be ignorant here, so, the RGB's in the led strips are different than say single 3w RGBs..etc. So each RGB would need it's own board and resistors?

ok... here is the link to the mini controller: http://www.ebay.com/itm/New-12V-Mini-Controller-For-RGB-LED-Lights-Strip-/360516962744?pt=US_Lighting_Parts_and_Accessories&hash=item53f07c49b8 and here is the link to the 3w RGBs...

yes, they are dumb... no DMX, so really, it's just a matter of not overloading the controller. The 3w RGB are max of .350a per ch, so little over 1a with all on. With the controller handling 12a, I figure I can wire 10 of the RGB modules together with a single controller be ok. The...

Any parts listed for build, or instructions?
