Hey all,
I got a projector (minus diodes) for cheap, and I have extracted quite a few things, including the precious phatlight. Now I powered it up via my small power supply-- 2A @3V DC, and while that's quite nice for a quick test, I need to figure out a driver for it, and a driver for the TEC it's attached to.
If possible, a driver for the phatlight that I could adjust the current on-the-fly with a pot would be nice, but otherwise, I need something that can do maybe... Somewhere between 4-8A at 3V DC (that's what I want to run it at, right?). Anything in that range would be fine. And I have no clue what a driver for the TEC would look like, or what voltage it needs.
Basically, I need to know what drivers I need to be able to power:
1x Phatlight at around 6 amps input. Not sure what voltage, around 3V DC most likely.
1x TEC. I think it's 12V DC, not sure.
1x Fan. No clue at all what I'll need to run it as.
I'm not very good with drivers and voltage stepup/stepdown and amperage limiting, so advice would be great.
I don't mind buying from DX, in fact, cheaper is better.
I plan on using the stock heatsink and TEC and fan in order to achieve max heat conduction ability. I will either run this off of a bench supply, or mount it in a large roomy plastic host, with the fan installed and running from either a bench supply OR a large LiPo cell battery.
