Recently my friend Ilan happened upon the control consul for an old scanning electron microscope on reuse. At MIT it is common for people and labs to post stuff to firstname.lastname@example.org, which means that it is free to whoever wants to take it. The idea is more free stuff and less trash.
I don’t know too much about electronics, but I can appreciate that this machine was beautiful. We took it apart to salvage parts and took pictures along the way. It felt quite criminal to be ripping it apart. If you know stuff about anything you see, please share!
