Tim Cowden (Cowlander on the forum) has been using a Teensy 3.5 to build a controller for a cyclotron particle accelerator.

As part operations staff at the Cyclotron Institute at at Texas A&M University, Tim is responsible for the control systems.  He’s been working on replacing the Rabbit 3200 embedded controller they’ve been using with a Teensy 3.5.  The Teensy 3.5 has proven to be a good fit when combined with a Wiz850 network module.
