Open Source Soldering Iron firmware

Project mention: Accessing the Pinecil UART with Picoprobe | news.ycombinator.com | 2024-01-30

So apparently the Pinecil is a BLE-enabled soldering iron with a 108 MHz RISC-V processor running a custom real-time operating system [0]. The author wanted to access the UART logs, so they repurposed a Raspberry Pi Pico (a dual-core microcontroller system running a real-time OS) for the task.
That's a staggering amount of hardware, sortware and computing power devoted to decoding one of the simplest and oldest serial protocols from a device whose sole purpose is to essentially melt tin. Maybe I'm out of touch, but I think I'll stick to my thermostat-controlled Weller soldering station and FTDI UART converters. I apologize if this post comes across as snarky, my point is that these are solved problems and have been for half a century.

Project mention: I made a tachometer/hour meter for my outboard engine using the PIO | /r/raspberrypipico | 2023-04-28

Also, it looks like you're writing to the flash every second the engine is running. Do you have an idea of what the endurance of that might be? I'm not too familiar with this but supposedly the flash on the Pico is good for at least 100K program/erase cycles and Micropython uses LittleFS on RP2040 which does wear leveling. I looked for more official info and the rp2 port code backs that up with a note: "the flash requires the programming size to be aligned to 256 bytes". And the littlefs readme does say it does wear leveling and other good stuff.
