http://www.reefcentral.com/forums/sh...postcount=2245. but I have no idea where to start.
if you gonna to give it a try maybe we can do a group by but I have to say that i don't know the component list, where to buy them, how to weld each component in the board...
may we can help each other, you do list all components, LM3409HV board, arduino, for both projects and I pay it all, sounds good uh?
