Not sure how in debth you want to go into testing but a portable switch matrix would be a fun project to build.
My most valuable tools on my bench (as far as frequency used):
- strong light with large mangifying glass on a swing arm.
- Soldering Station (and desoldering iron)
- Multimeter
- Oscillos...
