I will be using an Arduino to make this jig. Arduinos are very standard, easy to power and are a breeze for short projects like this. You'll also want a proto shield PCB

I think I'll put the victim...like this!

Mark and drill the mounting holes - four in this case. Luckily (or on purpose???) I placed the mounting holes on 0.1" boundaries.

Solder wires from each pogo pin to a matching pin on the shield. For this SD card interface I connected the SPI pins to the SPI port. Then the output of the 3.3v regulator goes to an analog pin. I also connected the card detect pin up so I can tell when a board is being tested.

A piezo buzzer is connected to pin #9 (underneath the PCB).
