Model Forum / Radio Controlled / Air Models / June 2008Power supply conversion
I bought 10 AT style computer power supplies. I have converted two into a modeling power supply that provides both 5 and 12 volts. They run my charger and receivers/servos, but not my foam cutting hot wire. I want to sell the remaining 8, along with directions. The final cost to do a conversion would be about $40, including shipping and parts. Is anyone in this group interested, or should I put them on ebay?

Try http://www.mpja.com/products.asp?dept=465&main=1; if you need less current try http://www.mpja.com/products.asp?dept=475&main=1. How much current do you need for foam cutting?

Puts out 12v at 10 amps, 6v at 10 amps, and blarch googens at 11/34 verbitt. Only cost me 6' of catgut and a femur.

I'd like it back please. Well, I had 145 of em and the extra one just didn't fit in the case. >> Did mine using a pair of snipe, 3 small jackalopes, 6 grams of well aged >> toenail clippings, a Steve Miller Band "The Joker" 8 track tape, and an [quoted text clipped - 23 lines] >>>> >>>> Randy |
