A thermal printer,... Ideally, a Raspberry Pi with Bluetooth,...Node.js 10, Yarn, Python 3.7, Docker...An iPhone for the app, "
Nearly forty years ago I implemented a till-roll printer for logging alerts on a UPS. It ran on a 6502 1 MHz SBC with 2 k bytes of RAm and 8 k bytes of EPROM. The 6502 also did all the measurements.
Before anyone complains that my old system did rather less; yes I do understand that, but it still seems to me that both the hardware and software requirements for the Tinyprinter seem rather excessive.
Wouldn't it be possible to just use an ESP32 to do pretty much all of it?
