mntmnwe looked into wood recently and it's probably not a good material for hardware cases... to recycle it you need glue for example00:02
mntmnaluminum is extremely recyclable00:03
mntmnnot sure if the quote on wikipedia is reliable, but > Today, about 75 percent of all aluminum produced in history, nearly a billion tons, is still in use00:04
technomancythat's awesome00:04
technomancyI mean, wood is still a big step up from plastic00:05
technomancybut aluminum is better for this00:05
mntmnsure, wood is at least something you can regrow00:05
technomancyand it seems like you would need a lot thicker hardwood to get the strength you'd need for the reform case00:08
technomancyvs like ... a 300g keyboard for instance =)00:08

robinthis sounds interesting but is evidently at a very early stage: https://libre-soc.org/06:48
robin(and of course there's already microwatt for fpgas and whatever the powerpc-notebook.org people are using, both of which have the distinct advantage of already existing)06:50
robinthe powerpc notebook evidently uses the "NXP T2080 e6500 64-bit Power Architecture® Core Technology 4 x e6500 dual-threaded cores, low-latency backside 2MB L2 cache, 16GFLOPS x core" cpu, which has no gpu and, in their design, uses a traditional motherboard06:52
robin(per https://www.powerpc-notebook.org/faq/)06:52
robinwhich sounds like more appropriate for their project or the framework laptop than the reform06:53
robinbut projects like microwatt could still be interesting for fpga soms06:54

robini don't quite get how this is feasible given the nature of libre-soc's TODO items, but there's this: https://hardware.slashdot.org/story/21/07/10/0154220/libre-socs-open-hardware-180nm-asic-submitted-to-imec-for-fabrication07:00

robinthis being an lkcl project automatically makes me a bit skeptical for various reasons, but a number of talented people and important groups seem to be involved, and if it works and and can be scaled down (nm-wise) and integrated into a reform-compatible som without running too hot...that's a very interesting alternative to arm07:06

KoodaJust flashed my Reform’s LPC+keyboard for the powersave modes. Slight annoyance with the update: you can’t turn on the Reform without the batteries installed anymore.19:10
Ar|stote|isAny place to get ahold of batteries in Europe? Locally (Greece) I can't seem to find those, and the only one LiFePO4 I could see was less mah too.19:15
Lewis[m]I'm not sure, but the brand matches, maybe these ones are the ones in the images on the reform website? https://eu.nkon.nl/rechargeable/jgne-18650-1800mah-5-4a-lifepo4.html19:27
erlehmann> you can’t turn on the Reform without the batteries installed anymore19:28
erlehmannKooda can you figure out why that is the case?19:28
erlehmannit sounds a bit weird19:29
Koodaerlehmann: I suspect this part of the change is the culprit: “In undervoltage condition, LPC turns off the SoM autonomously.”19:35
KoodaWithout batteries, every cell reads as 0V19:35
Ar|stote|isLewis[m]: hm thanks for that, I guess I'll order 9 a replacement for my dead one and one for each and every battery.19:40
Ar|stote|ishm i wonder if you could take one battery bank off replace the batteries and plug it in to have unlimited battery run time19:41
Ar|stote|isif anyone else has another source for batteries, either the same or higher capacity ones please say so.19:42
Ar|stote|isIs there a way to have the reform cut off power when the cells are too low in voltage? I haven't used mine much since 3 cells were drained too much, I could revive 2 of them but the third is reading almost 0V no matter how many times and how long I tried to trickle charge it19:43
Ar|stote|isare there any other ways of trying to restore a dead/drained lifepo4 battery ?19:44
mntmnKooda: sorry, i just noticed that i forgot to push a fix for that before19:44
mntmnKooda: but i just merged that... so if you flash your LPC again it should be fixed19:44
Koodamntmn: awesome, thanks :)19:46
