Some time ago, I made a light following robot with CR3022 batteries and parts I had on-hand. That worked fine, but, I thought there was probably an easier way to make it.
Fast-forward to today, and the PCB robot that I constructed here was certainly not easier, but did teach me a bit more about PCB design. It could also be mass produced, at least as far as the actual board goes, so if I were to make a bunch of them, my initial effort would eventually pay off. Overall, I’d call this a successful project, and you can see the results and build process in the video below:
On that note, I may list these boards on Tindie or elsewhere at some point. If you’d be interested in that, email me at info@jeremyscook.com, or ping me on Twitter to let me know!
