Workspace for Electromechanical Innovation

Many Circuit Cellar readers dabble in both mechanical and electrical design. Jared Harvey -- a senior electrical engineer at Howell Laboratories -- recently shared with us a details about his home workspace in West Newfield, ME, where he tackles interesting electromechanical projects.

Some of Harvey's recent projects include FEA Magnetic encoder Analysis, Radio Propagation Analysis, and Solid Modeling and Gif Animation. He writes:

I have a small collection of electrical tools including HAMEG spectrum analyzer, DSO Quad, China logic analyzer, Metcal soldering station, and a couple misc bench top power supplies and misc function generators. It's pretty basic tools, and whenever I need real tools I have always had access to good NIST traceable tools at work. I have made a re-flow toaster oven out of an B&D Infrawave, which is PID controlled using a thermo-couple controlled and generates mostly IR as well as some conduction heaters in the bottom.
