Smecstim
Picture this: it's winter circa 2010 and you have a mid 80's turbo Chrysler ECU. You want to mess with the software inside it but don't want to go outside. So you decide to build yourself a bench rig that takes care of the pecualiarities around this individual control unit. The smecstim is the result of that. You can find most of the details about this at my smecstim github repo.
