The first successful prototype of PewtyBot.
Philip from Germany got in touch to tell me about a cool project he had seen that involved photoluminescent paper. He thought maybe PlottyBot could so something with it, and maybe it could, but not fast enough I thought. I knew exactly what I wanted to do with it though, with the PlottyBot software stack, but a different machine. I love that people get in touch to show me cool things. I’ve been working on plotters for years now, and in some sense it felt like I had turned every stone. Out of nowhere Philip got in touch and steered me toward a whole new area of exploration. Of course one can buy glow-in-the-dark paper, of course I can shoot lasers at it, of course all the algorithms I’ve been working on these past years lend themselves to this new endeavor. Well, with some tweaking :).
It was a real struggle to get Trinamic drivers working on a Pi, but I wanted to step up my motor stepping game. Once I figured it out, holy shit do they work! There’s much else to talk about here, but this isn’t the point of this post, I just want to capture the miletone that is shooting lasers super fast at photoluminescent paper. I still haven’t wrapped my mind around what this all means.
