Just thought I'd share a project I finished up. A local arcade was throwing out a pinball machine that had been stripped down (nothing left but the playfield, a few solenoids, and a transformer in the box); I picked it up and used the playfield as a centerpiece for a coffee table. Work log is here.
This has been quite a fun project stretched over a two year period (there were a few months when no progress was made while I focused on school). It's been quite enjoyable and extremely educational.
