What might you do with a few extra stereolithographic 3D printer parts? Why not make a galvo display and resurrect a couple of classic vector graphic games of yore? That’s exactly what [Matt] did. With a few extra Formlabs components and a Haskell implementation of Spacewar, [Matt] can kick back and blast his extraterrestrial foes on the surface of his Formlabs cover.
[Matt’s] source code drives the Form 2 controller board to output laser graphics on the surface of a Form 1 case. These parts might be a commodity for this Formlabs Engineer, but the output is nothing short of spectacular, given the game and USB drivers were put together from scratch. In case you want to give the Haskell source code a try, [Matt’s] kindly included an alternative software-only display using OpenGL.
Unless you’ve just upgraded from Form 1 to Form 2, odds are pretty low that you can pull this one off without breaking either your printer or your wallet. Fortunately, [Alvaro] has paved the way with a stellar galvanometer display that began as a few parts from eBay. At last! Once our Formlab printer warranties expire, we’ll know where to start looking for parts for that mosquito killer we needed.
