Well, if you're going to be so snarky - have you read what I wrote? Did you even look at the graphic you linked to? There is clearly a Molex to wall-wart connector, which I said I do not want. :banghead: I don't want wall-wart connectors. I want screw terminals than I can put stripped wires in. Stock, I have to de-solder the wall-wart connector and hard-solder in wires directly. I don't really want the Molex to wall-wart connector piece. I will admit I'm an outlier more than a couple standard deviations from what most people want, and I really do *NOT* expect Andy to cater to my oddball tastes. |

Why the hell do you need to desolder anything? :dunno If you don't want to connect it to a PC molex then just cut the molex off and use a terminal strip. |

I've been playing with the tlc5940s for a few days to create something similar and now it looks like I won't have to :) Great idea putting the flash on there. --- End quote --- Thats correct, the current is always 20mA. But connecting the LEDs in series would work. It doesnt use TLC5940 by the way though... |

--- Quote from: keefyboy on January 07, 2011, 11:19:53 am ---I'd prefer screw terminals on the power connection. As is, I'd need to de-solder the stock connector. Most people will (I think) use power taken from a PC power supply. I understand it, however, as the stock power connection is nearly impossible to reverse polarity. Maybe I'm just averse to wall-wart connectors.... :-[ --- End quote --- Yes I thought most people would want to power from a PC power supply so we provide a cable which plugs into the PC power supply! But some will use a mains adaptor (which we might sell at some time but are widely available) and this will plug into the connector on the board. I cant see how screw terminals can be better than this solution, you would need to cut off the connector on the mains adaptor and wire it to the screw terminals. |

I wanted to wire four RGBs together and then run them off three outputs ( plus one 5v contact). I can wire them in parallel to achieve this but it sounds like that won't work with your board and I don't think you can wire standard 4 lead RGBs in series can you? |
