Hacking a 10 Watt RGB flood

[marsh28]

On ebay, they sell remote controlled RGB 10 watt floods for as little as $20. I just bought one last week from an American distributor for $24. Although I know Ray Wu sells these with the DMX decorder already included, I'd like to attempt to hack this RGB flood and attach one of the cheapo 3 channel rgb controllers Ray sells. Does anyone know how this might be done? Here's a link to the flood I purchased...

it was orginaly hacked by someone over at DIYC.

In the end its cheaper getting the DMX ones from Ray

Can you just daisy chain the 10Watt one's together and connect a small power supply to each?

I had a similar concern a while back,

If you follow the process on Alec's page, i have found it easier to desolder the 3 surface mount resistors connected to the gates and make the connection there to the driver circuit. I broke the gates when trying to lift them and that meant replacing the devices. Given I didn't have surface mount parts available I had to squeeze a full size TO220 device in there. (it was actually two TO220 devices in the end and not easy to fit it all in!)
