I just doodled out the basic PCB requirements for my stealth 250W ITX PSU upgrade at work today. Gotta fire up the vinyl cutting plotter for making my first new PCB masks in a decade. CrapShack/PhoneHut is getting back to its RadioShack Roots just in time . . .
. . . they've got DS Copper Clad FRP & Etchant in stock again!
I've got what I need for converting the non-switching ITX PSU to a switching IIsi PSU in hand already. I can harvest the AC I/0 headers for installation on the adapter board, the Wiring Harness/Mobo Connector and possibly the two fuse holder clips off the DOA IIsi PSU's PCB. The power connector and wires can be desoldered from the ITX PSU's AC socket and then soldered to the fused output pads of the Adapter PCB. Then that can be plugged right onto the ITX PSU's input headers.
I'm going to go ahead and make a few simple home-etched boards for the project, with a prototyping area included for any Soft Power Shenanigans that might become necessary. I'll make sure the PCB is compatible with the Q700 Stand-In PSU I have on hand as well.
