esadThe other day I stumbled upon a netbook by Hercules (of graphics card fame) that was powered by i.MX5: https://www.wired.com/2011/03/at-least-theyre-cute-ecafe-netbooks-launched-to-dead-market/13:49
esadARM powered netbooks were the latest shit in the late 00s :) I guess iPad/tablets killed the market alltogheter13:51
esadOne more find from the era: https://en.wikipedia.org/wiki/Litl - the litl OS sounds interesting13:52
mntmncool thanks esad14:47
mntmnas i just posted in fediverse+twitter: > thinking about doing a Reform 2 beta program again (like with V1) with 10-20 early access devices, priced around 800-900 EUR.14:48
mntmnbecause anyway we'll have to build devices for internal testing/validation14:48
mntmnso we could as well build a few more14:48

Jookiamntmn: make sure to get a good battery protection circuit for the lipos18:13
mntmnJookia: not using lipos :)18:37
Jookiaoh, what are you using?18:37
mntmnreform is using lifepo4 to avoid the typical hazards18:37
mntmnalso has more recharge cycles. the tradeoff is less energy density18:38
JookiaWow, I didn't know those existed. I'm going to have to look them up some more18:39
JookiaWhat form factors are they in?18:39
Jookiaooh, 1865018:41
Jookiahaving batteries that don't explode without a protection circuit interests me greatly18:43
Jookia(for undervolting)19:00
adjtm_Jookia, I don't know why there not used more often, the energy density drawback is very little19:01
JookiaI might be wrong about the undervolting safety stuff. I spent last week trying to figure out battery stuff and protection circuits for a device I want to make19:01
adjtm_lifepo4 are less explosive, but I suppose they are not completely safe19:02
adjtm_using 18650 would mean a little less volumetric density for gain in convenience19:03
ieureIt would be nice if you could use 18650 and replace them fairly easily.19:10
ieureSaid as someone who owns old laptops with dead batteries which are very difficult to repair.19:10

mntmnieure: it’s exactly what we do20:08
mntmnReform 2 has 8x 18650 LiFePO4 batteries20:09
mntmnjookia, in my experience nothing bad happens when undervolting except that the batteries stop working well20:11
mntmnif you mean over-discharge20:11
