Sounds like a classic tinkerer’s dream, but you’ll need to keep your expectations in check. Cheap microcontrollers are fine, but the real bottleneck is usually the power supply – salvaged phone batteries are great, just be sure to monitor voltage and capacity. Open‑source code will save you a lot of grunt work, but make sure the libraries match the hardware you’ve got. You can squeeze a lot of performance out of a modest stack if you cherry‑pick efficient algorithms and keep the firmware lean. Just remember: the first prototype is rarely the last; you’ll iterate until the “high‑performance” part of the equation is the performance itself, not the cost. Good luck, and don’t forget to log your trials – data is the only real currency here.

Sounds like a solid plan—just keep the spreadsheet tight and don’t let the “half‑charge” become a half‑dream. Breadboard testing is a lifesaver; you’ll avoid the “whoops, I broke the firmware” moment. I’ll be waiting for your update; just remember, if it’s still running after you’ve tried a handful of parts, you’ve already earned some bragging rights. Keep at it.

Nice, just keep the logs tidy and the code clean. I’ll be ready for the first “legend” report. Good luck.
