@mntmn have you ever tried to source conductive glass? I've been looking into it recently (both sputtered and copper mesh) but I haven't been able to find a reference price (like, not even an order of magnitude)
@jacqueline the TPS25948 chip they're using for doing the parallel battery stuff is a cool find. it's an 8A efuse with all the typical trimmings like OVLO and UVLO, but the linear FET pair they use for inrush control and active current limiting also doubles up as an ideal diode OR so you can run them in parallel.
thread in which I talk about why the "wrap your games console in a towel" or "reflow the bga" thing works to fix some consoles, and it's nothing to do with solder balls.
when my Glasgow showed up I immediately got nerdsniped by the hardware design, which had a lot of neat tricks. I started digging through the schematics, figuring out how it all worked, and ended up writing a pretty comprehensive description of how the hardware fits together and behaves. and now, with assistance and input from the Glasgow folks, that documentation is now part of the official docs :)
@foone this is where KSP has spoiled me, by making me pay attention to delta-V numbers. "I could alter my velocity relative to this object by 800m/s, or I could expend 20m/s of dV to alter my approach angle by 2 degrees for the same result".
@mntmn btw, do you have any existing documentation published about your power domains and filtering? I always love digging through that stuff. (no worries if not, it's just academic curiosity, don't do any extra work on my behalf!)
@foone iirc one of the tricks was to add some sort of clear oil (like baby oil) to stick it to the PCB, which made the white paper go kinda clear.
the actual home etching process is super messy though. ferric chloride stains eeeeeverything, it's bad for your skin, and you have to neutralise it before disposal which also creates a lot of mess. I used to own a kit and used it only a couple of times because the cleanup is horrible.
