Show HN: I built a robot that draws caricatures with a Sharpie Hi HN, I’ve been tinkering with this for a while and finally have it in a decent state. It’s a plotter robot that draws caricatures from photos. I trained a diffusion model (Flux Kontext LoRA) on caricature images, 3D-printed a Sharpie mount for my Ender 3, and hacked together a pipeline that goes photo → caricature → G-code. After a lot of trial and error it’s working pretty well, and I put up a little site where you can try it out. Happy to answer questions or hear any feedback. Thanks! https://ift.tt/r7CQSoI August 27, 2025 at 09:27PM
