| noam | Pretty sure from reading the buck/boost converter datasheet but wanting a second opinion before doing something stupid: it _should_ be fine to connect less-than-perfectly-stable current+voltage to the Reform, right? Like, say, from a solar panel? | 00:00 |
|---|---|---|
| noam | The datahseet explicitly calls that out as a targeted use case, but I'm not 100% what the power path through the reform is, or whether supply voltage ever goes anywhere else | 00:01 |
| vagrantc | from what i recall the max input voltage is 28v ... a nominal 24v panel array might go as high as nearly 40 volts | 00:03 |

| vagrantc | with a 12v panel ... it is within the voltage tolerances ... though no idea if it is still well supported :) | 00:03 |
| vagrantc | i charge mine off a 24v solar system, but it also has a battery that "drags" the voltage down, and disconnects the panels if the voltage gets too high | 00:04 |
| noam | Panel is nominal 12V, and it seems to peak a bit under 20V | 00:04 |
| noam | What I'm doing rn is charging a battery off the solar panel, then connecting that to the reform | 00:04 |
| vagrantc | with a management controller, or just directly off the panels? | 00:05 |
| noam | The battery has a BMS, explicitly intended for usage with 12V panels, and possibly w/ 24V panels as well, I don't recall | 00:05 |
| noam | It's a portable one, battery's the wrong term | 00:05 |
| noam | "power pack"? | 00:05 |
| noam | The kinda thing people usually use for phones, but ~250Wh, and with DC5.5x2.1 in+out :P | 00:06 |
| vagrantc | can it charge while also providing power? | 00:06 |
| noam | No | 00:07 |
| noam | :/ | 00:07 |
| vagrantc | sorry i can't answer for sure if it is safe to just plug into the panels ... | 00:07 |
| noam | Hm, just looking at the board, there's a fuse by the DC jack | 00:08 |
| vagrantc | seems like *maybe* with the voltage your panels put out ... but would hate to burn anything! | 00:08 |
| noam | I *think* the worst case is I'd have to replace the fuse? | 00:08 |
| noam | vagrantc: I'm pretty sure the voltage will never go too *high*; I'm more concerned with what happens if both voltage and current are constantly fluctuating up and down | 00:09 |
| vagrantc | right | 00:09 |
| vagrantc | in my experience, the mnt/reform tends to draw a pretty consistent amount of current through it's charge cycle ... which might drop it below the minimum voltage, yeah | 00:10 |
| vagrantc | but it can certainly handle *some* fluctuation | 00:10 |
| vagrantc | will also be very curious to hear a more definitive answer, though! | 00:11 |
| vagrantc | might also be worth asking on the forum? | 00:11 |
| noam | oh yeah, fuse would only be the worst case if I was concerned about too *much* energy running through, I'm actually not sure what would happen... | 00:14 |
| noam | I'll need to check the schematic | 00:14 |
| noam | Or just try it and hope :P | 00:14 |
| noam | Looking at the LTC4020 datasheet, it looks like it *should* work. I'll just want to check the schematic first and make sure that the DC jack isn't routed anywhere other than to the LTC4020; if it isn't, it should be fine | 00:17 |
| minute | noam: i haven't tested it but it sounds like it should be fine... in any case i'll be interested to hear how it worked out | 00:32 |

| vagrantc | heh | 19:33 |

| vagrantc | minute: no, more a dock for the mnt/reform to plug a phone or something into and provide a keyboard, ethernet, monitor, etc. :) | 19:34 |
| vagrantc | i've speculated/wished about this in the past :) | 19:35 |
| minute | vagrantc: you mean something like a nexdock? | 19:35 |
| minute | Allie: the design is almost done! | 19:35 |
| vagrantc | minute: yeah ... turn a mnt/reform into a nexdock by swapping out the cpu module for some adaptor board ... | 19:36 |
| vagrantc | minute: last time i mentioned it you suggested that the hdmi -> edp adapter was a bit of a blocker ... but sounds like that's solved? :) | 19:36 |
| minute | vagrantc: hmmmmm i think i had a different concept of that. not with a phone. i thought with HDMI input | 19:37 |
| minute | kind of an inside-out module | 19:37 |
| minute | so the laptop would act as a hdmi monitor and a usb keyboard+mouse | 19:38 |

| josch | Boostisbetter: i bought this: https://www.foxint.com/home/product/fox-halo-96k-power-pack | 21:18 |
| * wielaard -> mjw | 21:21 | |
| Boostisbetter | josch: thanks! | 21:24 |
| Boostisbetter | minute: In general I would have both on me when out and about. Basically having a dual system, and the Reform could even charge the L5. To say that I would need it, is not really a thing. It is more just a convenience and I think it would appeal to quite a few people. | 21:25 |
| Boostisbetter | josch: do you think when the cells run down that you'll open it up and just solder in new cells? | 21:26 |
| josch | maybe -- but i think that will be a loooong long time until then | 21:27 |
| josch | and it might as well be that the charging circuit breaks before the cells do :) | 21:27 |
| Boostisbetter | I don't know. My eremit 2000 maH cell broke on my Reform after a little over a year. | 21:29 |
| josch | with the protected battery board? | 21:30 |
| vagrantc | minute: not having to sync files, configuration, etc. between your handheld device portable device that you might use out of your pocket while still being able to plug into a full keyboard when needed with a large battery ... the main way i would think of it | 21:34 |
| Boostisbetter | josch: yes I had the new battery boards. | 21:35 |
| Boostisbetter | But I also never let the cells drain like that. I always have the Reform plugged in. | 21:35 |
| josch | i've been at 0% (with the protected board) several times -- lets see how this develops | 21:36 |
| Boostisbetter | I am kind of thinking that the cell was just defective. the other 7, purchased at the same time are doing just fine. | 21:36 |

| minute | vagrantc: ah, i have a text file sync solution for my phone and computers so i don't need that usually | 22:17 |
| minute | i have a folder structure on a server that gets synced over syncthing to other computers and which is also accessible via webdav | 22:19 |
| minute | (the latter works well with iphone based text editors) | 22:19 |
| Boostisbetter | I use Resilio Sync to accomplish similar things. But like vagrant I can many uses cases for the Reform to able to function as a nexdock and KVM. | 22:24 |
| Boostisbetter | Can someone tell me how to hold an application back from apt updating it? | 22:25 |
| Boostisbetter | found it, apt-mark hold | 22:28 |
| Boostisbetter | That is a handy feature there. Particularly for my xmpp client. Newer version add features that are nice, but aren;t usable on the Penkesu. But being able to resize the contact list is important, with the limited display space i have there. | 22:34 |
| vagrantc | minute: sounds much more complicated than plugging into a doc with a keyboard and monitor :) | 22:35 |
| Boostisbetter | minute: one other reason why the nexdock solution is appealing is because for some reason, in my works infinite wisdom they would never let me register the Reform to use in my classified work space, but for some reason because the L5 looks like a phone they let me get it registered. So I can use the L5 at work, and this means that large portion of project work (private projects) could be done in | 22:36 |
| Boostisbetter | breaks etc. Then I could more easily hand things over instead of the shotgun sync approach | 22:36 |
| Boostisbetter | that resilio sync does. | 22:38 |
| minute | vagrantc: not for me, because i don't have to plug anything anywhere. my files are just there | 22:40 |
| minute | i can edit my markdown, todo etc on my pocket reform, reform, pc, iphone and i don't have to think about doing any syncing because it just works automatically | 22:42 |
| + kensanata (~alex@user/kensanata) | 22:48 | |
| vagrantc | sure, syncing is useful and all that ... but i guess i am sold on the phone convergence options and the mnt/reform seems "close" to having that functionality | 22:48 |
| vagrantc | or close to being able to provide that functionality | 22:48 |
| minute | totally unrelated: i think it would be possible to play fallout new vegas on the reform with a311d. but i have yet to attempt it | 22:48 |
