The global semiconductor shortage has caused havoc for a great number of industries. At the time of writing the supply of Raspberry Pi boards (particularly the latest Pi Model 4B and Zero 2 W) is almost non-existent.
Prompted by this video from leepspvideo I dug out a couple of old 512MB versions of the original Raspberry Pi 1 from 2012 and have put them to work in place of a couple of Pi Zeroes 😎
These boards are running the latest bullseye RasPiOS and I have used the overclocking settings suggested in Lee’s video:
arm_freq=1050 core_freq=550 sdram_freq=550 over_voltage=14 force_turbo=1
I also experimented with zram to speed up swap usage but I’m not convinced the IoT-like application these will be put to really needs it. YMMV.
I did find some better (smaller & PWM/GPIO controlled fans) but again, I’m not sure the light IoT-duty these boards will be put to really warrants extra cooling.
The hostname for this particular device evolved to “tm-raspiface” as I once contemplated using temperature-machine (where all hosts have names that start “tm-“). Originally the piface part of the hostname came from the fact this Pi was at one point wearing one of the first add-on boards (before the term HAT had been coined 🙂 ) the Piface Digital I/O board from 2012/3 😀
