#arcade I designed and a microphone configurations for a pair of glasses based hearing aid(clEar v2) that allows O(1) beamforming without interpolation. I also experimented with ways to separate voices, but need to do more research before i proceed github.com/arghunter/EyeHear

#arcade I made a trackball mouse using an Arduino and optical flow sensor I found. Admittedly the print failed, but I just improvised and it works pretty well. I'm thinking of making a second iteration with a usb->serial or rp2040 for better utility but its a pretty good stopping point (I put a bit more work after my last arcade session but forgot to track it)

#arcade I made a self-balancing robot named Gerald using a bunch of random parts i found. This is the third iteration of my design. I may need to update it as it isn't perfect, but I'm pretty happy with where it is right now

#arcade I made a rhombic dodecahedron with embedded magnets in its sides to allow it to connect to others. The shape naturally tessellates, allowing them to create space filling structures. Here is the github github.com/arghunter/Misc/tree/main/Rhombic-Dodecahedron-Magnet and here is an image of one

#arcade just made a remote camera monitor for my 3d printer. Its all from scratch and mostly based around command line tools Here is the session: hackclub.slack.com/archives/C06SBHMQU8G/p1719639519223869 and github: github.com/arghunter/3dprintermonitor/tree/main here is an image of the final camera setup
