XgFUgh, one of the batteries appears to be completely dead (reading 0v now)00:03
khm_my experience with lipo says that a flat battery might be recoverable with a low-current charge from a lab supply, but even if you recover it, it won't perform to spec, but have a reduced capacity :/00:05
AsmadeusXgF: I had the same issue, could recover 7/8 with a power supply but didn't find any way of putting life back into one that was reading 0V... some replacements being shipped now00:10
AsmadeusAt least it's a very standard model that's pretty cheap00:11
XgFWhere did you get your replacements?00:14
khm_In the US, you can get the same model that mntmn ships from here: https://www.18650batterystore.com/collections/jgne-18650-batteries/products/jgne-18650-180000:27
mntmnkhm_: ohh that's very good to know00:29
mntmnin europe i usually buy from nkon00:30
khm_I also got the nitecore sc4 but it was a mistake -- you have to manually select lifepo4 with each battery you insert.  I'll use it for my li-ion batteries, but I'm still on the hunt for the Most Convenient Charger00:34

khmdoes anyone have part numbers for the battery pack connectors?  I think I'm just gonna wire killswitches in to preserve charge over the weekends04:51
ex-parrotI thought about doing that too but I want to have a look at the schematic and see if there’s a tidier way 06:08
dopplerkhm: J2 and J13 on the motherboard are Molex 5040500591; the mating connectors on the battery pack end should be Molex 504051050107:08
khmdoppler: perfect, thanks07:08
dopplerthe BOM appears to be typo'd and they're all listed as 504050059107:08
khmex-parrot: I'd be interested to see what you come up with07:08

XgFnkon seemed to be out of stock, I ended up ordering from  BATTERIJSERVICE.nl, we'll see how that goes :-)09:42
mntmnXgF: keeping fingers crossed11:04
XgFThe pictures were an exact match of the ones that came with the reform :-)11:04
mntmnex-parrot: i think the cleanest solution would be to turn off the 3v3 standby power11:04
XgFThe other batteries are currently being cycled through my Nitecore charger to top them up11:05
mntmnat its enable11:05
mntmnXgF: ok cool11:05
mntmnex-parrot: U1411:06
mntmnex-parrot: if you remove R1 and replace it by a switch and a pulldown to gnd at U14, that should work. there still will be minimal leakage through the pulldown, though. if i understood correctly, U14 has an internal pullup on enable :/11:08

mtmgot a feeling I'll never see this issue; intend for the Reform to be my primary device.18:23
mtmmntmn: any chance mine was among the 25 you just finished? :)18:23
mntmnmtm: i also use my reform every day (night) and that's why the batteries never run dry.18:24
mntmnmtm: what's your order number?18:24
mtmcrowd supply 116407 18:26
mntmnmtm: sorry, these are not shipped by us at all now. these are post-crowdfunding orders that will be fulfilled by crowd supply from batches we send to them, after the crowdfunded orders are done.18:29
mntmnwe will still need around a month for the crowdfunded orders.18:29

mntmnwe're catching up slowly but surely18:33

ephaseHi!20:05
ephaseI've got a litthe problem with pulseaudio on my self made image disk for the reform2, there is no audio output20:06
ephaseI take the config files from the official mnt repo ... And sound on the official image work really well20:07
mntmnephase: is wm8960 probed correctly? there's a hardware bug that makes it disappear sometimes after a cold start20:23
mntmnephase: can you see it in alsamixer?20:23
mntmnephase: if not, you might need to do a reboot20:24
ephasehi mntmn20:52
ephasemntmn: yes I see it, I see vumeter move on pavucontrol, but no sound at all20:52
ephaseon speakers ot headphones20:52

ephaseok thanks22:42
ephasemntmn: I'll try to configure my reform with LVM and modify reform-init for it23:13
mntmncool23:15
ex-parrotmntmn: ty for that, U14 does look like a good candidate 23:41
ex-parrotanecdotally at least I’ve run swap on SSDs for years now without any apparent harm. You can usually query the SSD’s “lifetime remaining” with hdparm / the right ioctl and keep an eye on the write endurance etc too 23:42
ex-parrotcan always adjust “swappiness” on Linux too to make it write less often 23:43
