| XgF | Ugh, 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 |
| Asmadeus | XgF: 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 now | 00:10 |
| Asmadeus | At least it's a very standard model that's pretty cheap | 00:11 |
| XgF | Where 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-18650-1800 | 00:27 |
| mntmn | khm_: ohh that's very good to know | 00:29 |
| mntmn | in europe i usually buy from nkon | 00:30 |
| 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 Charger | 00:34 |

| khm | does anyone have part numbers for the battery pack connectors? I think I'm just gonna wire killswitches in to preserve charge over the weekends | 04:51 |
| ex-parrot | I 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 |
| doppler | khm: J2 and J13 on the motherboard are Molex 5040500591; the mating connectors on the battery pack end should be Molex 5040510501 | 07:08 |
| khm | doppler: perfect, thanks | 07:08 |
| doppler | the BOM appears to be typo'd and they're all listed as 5040500591 | 07:08 |
| khm | ex-parrot: I'd be interested to see what you come up with | 07:08 |

| XgF | nkon seemed to be out of stock, I ended up ordering from BATTERIJSERVICE.nl, we'll see how that goes :-) | 09:42 |
| mntmn | XgF: keeping fingers crossed | 11:04 |
| XgF | The pictures were an exact match of the ones that came with the reform :-) | 11:04 |
| mntmn | ex-parrot: i think the cleanest solution would be to turn off the 3v3 standby power | 11:04 |
| XgF | The other batteries are currently being cycled through my Nitecore charger to top them up | 11:05 |
| mntmn | at its enable | 11:05 |
| mntmn | XgF: ok cool | 11:05 |
| mntmn | ex-parrot: U14 | 11:06 |
| mntmn | ex-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 |

| mntmn | and with the batteries not removed | 18:19 |
| qbit | cool | 18:19 |
| mntmn | qbit: so you should just regularly charge it | 18:19 |

| mtm | got a feeling I'll never see this issue; intend for the Reform to be my primary device. | 18:23 |
| mtm | mntmn: any chance mine was among the 25 you just finished? :) | 18:23 |
| mntmn | mtm: i also use my reform every day (night) and that's why the batteries never run dry. | 18:24 |

| mtm | crowd supply 116407 | 18:26 |
| mntmn | mtm: 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 |
| mntmn | we will still need around a month for the crowdfunded orders. | 18:29 |
| mntmn | (those are orders placed before june 18, 2020) | 18:29 |
| mntmn | the last crowdfunded order number is 98xxx | 18:30 |
| mntmn | mtm: when did you order? | 18:30 |
| mtm | March 13, 2021 | 18:32 |
| mntmn | oh that's kind of recent! | 18:33 |
| mtm | so I stil have some waiting to do :) | 18:33 |
| mntmn | a bit, yes | 18:33 |
| mtm | yeah... | 18:33 |
| mtm | okay | 18:33 |
| mntmn | we're catching up slowly but surely | 18:33 |
| mntmn | at least we have all of the parts in stock! | 18:33 |
| mtm | good deal | 18:33 |

| ephase | I've got a litthe problem with pulseaudio on my self made image disk for the reform2, there is no audio output | 20:06 |
| ephase | I take the config files from the official mnt repo ... And sound on the official image work really well | 20:07 |
| mntmn | ephase: is wm8960 probed correctly? there's a hardware bug that makes it disappear sometimes after a cold start | 20:23 |
| mntmn | ephase: can you see it in alsamixer? | 20:23 |
| mntmn | ephase: if not, you might need to do a reboot | 20:24 |
| ephase | hi mntmn | 20:52 |
| ephase | mntmn: yes I see it, I see vumeter move on pavucontrol, but no sound at all | 20:52 |
| ephase | on speakers ot headphones | 20:52 |
| mntmn | ephase: hmm there might be a control turned off/down in alsamixer that pavucontrol forgets | 20:57 |
| ephase | mntmn: got it! | 20:57 |
| ephase | Right / Left Out Mixer PCM was off | 20:58 |
| mntmn | ah good | 20:59 |
| ephase | thank you mntmn ;) | 21:00 |
| ephase | Doessomeone test btrfs on Reform for daily driver filesystem | 21:05 |

| ephase | mntmn: I'll try to configure my reform with LVM and modify reform-init for it | 23:13 |
| mntmn | cool | 23:15 |
| ex-parrot | mntmn: ty for that, U14 does look like a good candidate | 23:41 |
| ex-parrot | anecdotally 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-parrot | can always adjust “swappiness” on Linux too to make it write less often | 23:43 |
