VictualSquid posted:Hadn't thought about it in some time, but has anybody ever developed a good way to reboot a headless rpi? You can try looking into using a hardware watchdog which should come with most rpis. The nice thing about the watchdog is that it reacts when there is no activity. As in, if no one checks in with the watchdog, the watchdog reboots the machine. This works better than a process that reboots if it doesn’t detect a connection, since there is no recourse if the process crashes or otherwise is unresponsive (save for rebooting manually).

Depends on what you need, but they have variety packs of various things electrolytic capacitors https://www.microcenter.com/product/632685/inland-047uf-1000uf-electrolytic-capacitors-assortment-kit-13-values-200-pcs ceramic capacitors https://www.microcenter.com/product...-values-550-pcs resistors https://www.microcenter.com/product/618897/inland-1-4-watt-1-resistors-480-pack also diodes, breadboards, and they usually have raspberry pi in stock

DerekSmartymans posted:I put Raspberry Pi OS on my x86_64 Intel laptop from ~2011ish. It’s got a 128Gb SATA SSD, and 8Gb of RAM, that had been used as a ghetto NAS with a few Tb of old spinner-platter HDDs connected via SATA>>USB cables stacked on my dad’s old piano. It had been running the free version of TrueNAS Core. Sounds like fun! I’d love to hear more about it in this thread when you make progress. It hasn’t ever really occurred to me that arduinos and rpi devices could be repurposed into an oscilloscope… I should probably look into that, particularly because of the pio capabilities of the pi nano.

. I might X-post this in the general Linux thread, because I’m still definitely a n00b enough with the Pi/PiOS ecosystem that I’m sure I’ll have a bunch of questions as I go. My hope is that I can get beyond simply “following a recipe”-type work and actually understand what I’m doing as I go along.

Warbird posted:Is there any good guidance on hardening a Pi or similar for edge work in a less than hospitable environment? I have an ADSB Pi doing its thing up in my attic but the combination of humidity/heat/cold throughout the year has something failing fairly often and usually requires a power cycling to get working again. It's a Pi2 iirc so that's not helping anything, but I also suspect the SD cards are also not super happy as those have to get cycled fairly often despite log2ram and making sure I'm using "quality" ones. Pi should be fine. If you can completely eliminate any writes to the sd card as much as feasible, you’ll get much more life out of it. Alternatively, you can put a usb drive on it and write to it. You can try enabling the watchdog so that the device can reboot if it crashes. One thing you should check is the power supply. Make sure you have a decent cable and that you put out enough volts to prevent undervoltage, which could lower the lifespan of your parts. You may even want to replace it just in case, since a power supply running continuously will certainly be running hot and thus have a lower lifespan. The pi2 has some interesting deficiencies. Maybe try a pi1 if you have a spare?

Well, with the adoption of RISC V going higher and the continuing interest in using it in hobbyist situations, I think that there are enough small business and talented hobbyists that would be down to beef up a good implementation. Until then, there’s enough profit in maintaining goodwill that I think raspberry pi will keep maintaining their current and legacy platforms. Besides, due to how much demand there is, they are quite happy with churning out good product at the current prices. Makes for a good prototype board!
