Hi all, Haven't started the experiments yet, but I have new information that might change things. It turns out that all I will need to control for this version are a bank of up to 3 Superflux LEDs. Total draw, under 0.2A (generously, I'm looking to run them closer to 150mA, and I'd guess even that will be too bright). I am also having some spacing issues jamming the TO-220 packages into the enclosure. Remember when I said the board already had provision for a transistor on it? Well, I found this part: http://www.digikey.ca/product-detail/en/SSM3K333R,LF/SSM3K333RLFCT-ND/35223= 91 (a Toshiba SSM3K333R) in SO23 that would match the footprint already on the board. I'd have to scab on a pull up resistor, but that wouldn't be too bad. Gate resistor already has a footprint. Any thoughts? It sets me back a bit as I'll have to wait until Tuesday to get the parts, but might be worth it given how much time I've been staring at the enclosure trying to figure out to squeeze things in there in a way that isn't horrible.
