   Thanks! The biggest obstacle to running forever may be the chemistry of the li-poly battery which has a relatively low number of charge cycles and is known to degrade over time. A promising option is li-ion capacitors or supercapacitors, wh

   I've never looked into Forth, but I'm sure it would be doable. I have experimented with adding Uxn support, which may be similar to Forth in many ways? https://100r.co/site/uxn.html

   Thank you! Not many features of note - it runs arbitrary lisp code, has a simple graphics interface. You can save and load code and data/text files to SD card. The processor is the Ambiq Apollo3 Blue, which is really what makes running

   Thank you! Mosh is great, I have found it very helpful at times in my day job. SSHing into servers in Australia from Norway, the latency was pretty bad. Have not started working on wireless yet but I hope to get to it. The SoC i use has Blu

   Thank you! Not too much really. I "ported" it to the SparkFun arduino core - which mostly involved adding some ifdefs and fixing a few bugs, like this one https://github.com/sparkfun/Arduino_Apollo3/issue

   Thanks! Have not had the chance to do too much lisp hacking yet though, I still very much consider myself a beginner. Mostly solder and C so far, apart from implementing a crude text editor.

   12000 mAh battery / ~2 mA power consumption when running code and updating the display every second = 250 days. Still pretty good? Haven't had a chance to do much testing of the solar panel yet, but it does charge while running in

   I've considered adding a few small geared stepper motors as a combination input device (scroll wheel, or two for etch-a-sketch cursor control) and energy harvester.

    Yeah, it is used in https://www.freethegameboy.info for one - not sure if they published numbers on how much energy it produced.

    Yes, I would say that in light of recent happenings in the C++ Foundation board and committee ANYONE would be discouraged from participating in them, and by extension, the language. And I would expect that women and persons LGBTQ, having a
