An interesting mod you have there

is there anyway I can buy one of these power supply?

I have no intention of selling them, but I am more than willing to help you make one. It's really easy, you only have to solder 3 parts and 2 bolts so even if you never soldered before you shouldn't have too much problems (and it's always good idea to learn new skills).

How did you solder the bolts? Should be pretty hard to get good wetting with a regular soldering iron. Maybe it'd be wise to solder them first with a torch?

No, it went remarkably easy, used my normal 50W temp control iron (set to 420 C)... I just used a "third hand" to hold everything in place and used alot of flux (chinese made

). Did burned my fingers thou
