Used to! I restored vintage oscilloscopes, played around with high voltage and low noise power supplies, and did some microwave stuff, too. Of the scopes I used, one was a tek 556 dual beam vacuum tube scope, and the other a 2 GHz lecroy for everything else. I had a 20 GHz specan, 6 GHz VNA, a handful of power supplies, hot air rework and all that good stuff. Now I’m doing a postdoc and have joined a group that’s much more tinker-oriented so the lab I work in is a big mix of research stuff with a few personal projects. The major one now is a machine for rewinding the specialized HV transformers in the 500 series scopes that I love so much.
