I split this topic away from the MR16 thread to avoid confusion for others
Tom Question: Will you be producing a pcb run of those ATX Adapter boards?I doubt that there is a real demand for these but i could be proved wrong - this is more aimed at the home etch crowd. I'm happy to send these out to any Aussie members in exchange for a couple of dollars but the postage to the US would be a killer
Tom Question: I didn't see a visible load resistor. Is it behind the main ATX connector?the original pictured board was just a quick proof of concept and an exercise in etching, the design below does have room for a load resistor.
All
I have designed a little 3" x 2" single sided PCB that has 24 pin and 4 pin sockets along with output screw connector, switch and led so that ATX Computer power supplies can be quickly converted to standalone Power supplies.
Below are scans of the etched board i did a few days ago, along with a component overlay just waiting on parts from Mouser to confirm everything fits.
The BOM from Mouser to fully populate this board with all the connectors and parts is just under $9 US, however the 24pin/20pin (J1) and 4pin (J5) Motherboard power sockets could be recovered from a dead motherboard (it's what i did for the first board)
J3 and J4 are IDE drive power sockets and are optional unless you are drawing high amps.
Switch (S1) is a PCB mounted SPST switch, any panel mount switch could be used if you soldered wires in.
As soon as i confirm that everthing fits i will post the PDF's for the copper sides.
Cheers
