Really though, the RPi's config.txt is exactly this kind of rabbit hole. I just got a Zero W today and now I'm thinking about if it's possible to underclock it enough to power it with a lemon battery via GPIO.

- echoradio 6y agoIf you do the latter, will you please write about it and share here?
- Uehreka 6y agoThat was a joke. Was. According to this video I’d need a wall of lemons to get 5V with support for 300mA of current: https://youtu.be/a1D-fZP8qJk?t=205 https://youtu.be/a1D-fZP8qJk?t=205 So it may take some... adjustments... to get something like this to work, but I’ll see what I can do.
- dylan604 6y agoI have more fun with Arduino type boards than RPis. For me, RPis are just fun to see where you can put a little computer, but I like all of the soldering, bread boarding, wiring, etc of the various shields in the Arduino realm. I get the best of both worlds with the analog/digital inputs, plus the programming in a very limited (requires some creativity) fooprint type of challenge. I haven't messed with the GPIOs on a RPi though, but now we're back to just programming in whatever unsconstrained/unrestricted way of a desktop. ??? we all like different things.
- jnwatson 6y agoThe downside of embedded system is it eventually turns into enterprise hardware. A RPi is just a small cheap PC now.
- neuronic 6y agoIf you don't step away from it everything eventually becomes enterprise software.
- Dylan16807 6y agoIt ever wasn't? It used to have significantly more performance problems, but it's always followed the basic form of "tiny PC with IO pins and overbearing GPU".
