Thank you Mark. I like this project a lot - It's a neat looking little machine and clearly this guy's put a lot of time into the design. I've toyed around with the idea of using a Compute Stick or similar - This would also seem to allow machines a good bit smaller than mine, as in the videos you've linked. The biggest issue I've come across is the lack of neatly integrated battery management i.e. a battery and charger than the OS is aware of and able to control
(or at least react to
). I looked a bit into a USB protocol that's used by some UPSes whereby the UPS appears to the OS just as a laptop battery would - I believe there have been some efforts to implement this on an Arduino so it should be possible to take one of the various 'battery management' boards designed for the Raspberry Pi and interface it to a Pi, Compute Stick etc. via an Arduino
(or similar microcontroller
) pretending to be a UPS. I didn't get beyond looking into it because this level of tinkering is beyond me - I can do some basic Arduino stuff but when we get to USB device descriptors etc. I'm lost.
It's always interesting to see what others are doing, and often they've tried something I wanted to try which is very useful - I really need to document my project better but I'm prone to re-using as many parts as I can so most of the time it's little more than a pile of parts on a bench - I can at least start a bit of a journal of what I'm doing though.
