|---|---|---|
| tumbleweed | I can help ... maybe :P | 00:10 |
| tumbleweed | also o/ from JFK - I'm on my way back from CPT | 00:10 |
| CarlFK | never mind, turns out I did my thing... | 00:10 |

| CarlFK | hit tings with a hammer until lanchpad stops rejecting them | 00:11 |
| tumbleweed | :P | 00:11 |
| CarlFK | once we figure out what we are using, I would _really_ like you to do them right | 00:11 |
| CarlFK | but for now just trying to get micolous stuff up | 00:11 |
| tumbleweed | pragmatic :) | 00:12 |
| micolous | It's ok, there are wily packages | 00:13 |
| micolous | tim had me install xilinx sdk last night | 00:13 |

| xfxf | mithro: LCA own 7 active HDMI > VGA converters. i've just tested the output of HDMI2USB with one of them into a monitor with VGA and it appears to work | 02:37 |
| xfxf | mithro: i suspect will need VGA > HDMI for each room for the people who have VGA only. any idea of converters/adapters to use which are HDMI2USB friendly outside of expensive scan converters? | 02:38 |
| xfxf | well, sorry, i don't suspect, i've been asked to ensure we're covering for that | 02:38 |
| CarlFK | xfxf: 720p -> vga, right ? | 02:38 |
| xfxf | yes, 720p | 02:39 |
| CarlFK | I think mithro is planning on the vga daughter board being ready, so I would wait a bit on an answer before you buy anything | 02:39 |
| xfxf | okay, just again avoiding getting to the hackfest and pissing off LCA by having to emergency buy expensive things which are a fraction of the cost if bought in advance | 02:40 |
| xfxf | definitely want to lean towards perhaps purchasing a little too much over last minute panics :) | 02:41 |
| CarlFK | I remeber him saying he would cover the costs if he didn't deliver. but I was only 1/2 paying attention to what it was he said he would deliver | 02:41 |
| xfxf | (AV gear from local retailers in AU is expensive++++++) | 02:41 |
| xfxf | i remember him saying that too, i don't think that's fair on him at all | 02:42 |
| tumbleweed | xfxf: I haven't yet found a VGA->HDMI convertor that offers a 720p mode | 02:46 |
| CarlFK | tumbleweed: you were looking for < $100 things right ? | 02:47 |
| tumbleweed | yeah | 02:47 |
| CarlFK | I am sure I saw one for $350 | 02:48 |
| CarlFK | j | 02:48 |
| CarlFK | k | 02:48 |
| tumbleweed | there are presumably fancy ones that work | 02:48 |
| CarlFK | I took a 1/2 day fpga class and vga signal processing was a good bit of it. | 02:48 |
| CarlFK | seems it is pretty easy to word word word and great success. | 02:49 |
| tumbleweed | :P | 02:49 |
| mithro | xfxf: If you need to support VGA in, you'll need VGA->HDMI adapters | 02:50 |
| mithro | The HDMI->VGA side was the part which I'm confident about | 02:51 |
| CarlFK | oh oh ;) | 02:54 |
| xfxf | okay, i haven't a clue what's HDMI2USB compatible, any ideas? | 02:54 |
| mithro | Not really | 02:56 |
| mithro | xfxf: start with the cheapest thing you can find and work upwards? | 02:58 |
| mithro | xfxf: I have roughly 20 little USB screens here - are they useful for anything? | 02:59 |
| xfxf | i don't think i have time to do that anymore - we're 2 weeks out from the hackfest | 03:00 |
| mithro | xfxf: the cheapest ones are going to be easier to find right? | 03:02 |
| xfxf | cheapest in my eyes is buying something from overseas | 03:02 |
| xfxf | converters aren't cheap locally | 03:03 |
| xfxf | 2 weeks isn't sufficient to order something, then order something else | 03:03 |
| CarlFK | xfxf: how many do you need? (5 rooms, right?) | 03:03 |
| mithro | Yes | 03:03 |
| xfxf | 5 rooms yes | 03:03 |
| mithro | I meant locally | 03:03 |
| xfxf | and i don't have infinite funds to buy a bunch of random adapters | 03:03 |
| mithro | What does jaycar and DSE have available? | 03:04 |
| mithro | And how do they compare to your high end scalers | 03:04 |
| mithro | Can you when get your expensive scalers in time? | 03:06 |
| xfxf | jaycar/dse converters are terrible and overpriced, they're not remotely as close (none of them let you control input/output resolution - that said we don't need that), and perhaps | 03:19 |
| xfxf | i've got a few cheaper adapters here, i'll try to test them | 03:20 |
| xfxf | the jaycar/dse stuff is all targeted towards consumers trying to hook things to their HDTV's, not quite what we're doing | 03:22 |
| mithro | Yes, but are there many other options? If VGA scan converters are like $500 Aud | 03:22 |
| mithro | Being targeted at TV's is good as they do 720p | 03:23 |
| xfxf | less so quality, more being dubious that they'll work at all | 03:23 |
| xfxf | i bought them for my blackmagic gear, didn't work | 03:24 |
| xfxf | but will test | 03:24 |
| CarlFK | I bought a $45 one, wow was it crap | 03:24 |
| xfxf | the 'expensive' scalers i like because you can lock down the input/output resolutions | 03:25 |
| xfxf | so they tend to work with everything | 03:25 |
| mithro | Yes, but with the blackmagic gear we can't figure out why it's crap | 03:25 |
| xfxf | but at this stage i'll take whatever works | 03:25 |
| mithro | With the HDMI2USB we can see why | 03:25 |
| xfxf | sure, well, i'm confident i can buy 5x active VGA > HDMI adapters, but i've got zero way to know what they actually do | 03:26 |
| xfxf | if you think we can get most things working then i'm happy to do that | 03:26 |

| tpb | Title: PCT-VHC11, VGA to HDMI Converter , with RCA cable, (at www.umart.com.au) | 03:27 |
| xfxf | i have one of these | 03:27 |
| xfxf | will test it now | 03:27 |
| mithro | If jaycar is $100 per room and good converters are $150 - then go with the good | 03:27 |
| xfxf | the good are $400-$500 second hand | 03:27 |
| xfxf | and almost $1k new | 03:28 |
| mithro | If jaycar are $50 and good are $500 - then we probably need to make do with jaycar | 03:28 |
| mithro | Can you hire them? | 03:29 |
| mithro | Time verse money trade off | 03:29 |
| xfxf | yeah but they'll be almost as much to rent for a week | 03:35 |
| xfxf | this is why i bought mine | 03:35 |

| tpb | Title: Extron RGB HDMI 300 A | eBay (at www.ebay.com) | 03:39 |
| mithro | CarlFK: seems to cheap - but cheap enough that it might be worth the risk | 03:40 |
| CarlFK | its $350 new | 03:40 |
| CarlFK | Extron is the company that xfxf recomends for scalers | 03:41 |
| CarlFK | I kinda looked into this about 6 months ago | 03:41 |
| CarlFK | I should grab that for me... | 03:43 |
| mithro | CarlFK: probably | 03:43 |
| xfxf | that's a model i'm not familiar with | 03:43 |
| mithro | Extron is a horrible company, and their gear is overpriced expensive crap | 03:43 |
| mithro | *but* | 03:43 |
| mithro | that applies to pretty much everyone in the A/V space | 03:44 |
| CarlFK | lol | 03:44 |
| xfxf | i assure you it's better than the shit AU retailers sell | 03:44 |
| mithro | and they are better then most in the space | 03:44 |
| xfxf | yeah, well, how long until hdmi2usb does scaling, huh? ;) | 03:44 |
| mithro | xfxf: actually - that is something I could get florent to work on during the hackfest :P | 03:44 |
| xfxf | also, mithro, verifying something i spoke to you about a few weeks ago | 03:44 |
| xfxf | costa hall, the keynote venue, will have two lecturns. it's a VGA projector/system | 03:44 |
| xfxf | venue is quoting a VGA switcher | 03:45 |
| xfxf | i think we should forgoe that, and put a HDMI2USB in w/ my expensive HDMI > VGA scaler | 03:45 |
| xfxf | and use that for capture + switching | 03:45 |
| xfxf | seems sane? | 03:45 |
| xfxf | only fun thing there is the podiums may not be near each other | 03:46 |
| xfxf | and i know you wanted short lengths between laptop + hdmi2usb | 03:46 |
| CarlFK | xfxf: given the quantity of problems, I would not take on more | 03:46 |
| xfxf | CarlFK: it's not so much that, it's more having a VGA switcher in the mix complicates things for us | 03:46 |
| mithro | xfxf: Can you do a quick paper diagram (or Google Drawing) of what you are saying we should do? | 03:47 |
| xfxf | not right now, i'm not meant to be working on any of this currently sorry | 03:47 |
| xfxf | i'm neglecting other responsibilities | 03:47 |
| CarlFK | xfxf: opsis board next to each podium, hdmi->vga -> whatever the venue does | 03:48 |
| xfxf | the purpose of the opsis board also to do vision switching for what everybody sees on the main screen | 03:48 |
| xfxf | this cannot be done with 2x opsis's currently | 03:48 |
| CarlFK | you are adding reqirements | 03:49 |
| CarlFK | use the opsis to record, let the venue do the switching. hopefully they can handle that part ok. | 03:52 |
| xfxf | it means we can't use the hdmi2usb like in all other rooms | 03:54 |
| xfxf | we have to place it after the vision switcher, which means converting the signal | 03:55 |
| xfxf | that said i hear your point | 03:55 |
| xfxf | lets not complicate this anymore | 03:55 |

| xfxf | mithro: i assume you're aware of pink/red text that goes through output0/output1 on the hdmi2usb looking really pixely? | 04:20 |
| mithro | xfxf: no | 04:20 |
| xfxf | mithro: i've been using my windows computer the last few days fed through a hdmi2usb to ensure it's stable | 04:20 |
| mithro | xfxf: example? | 04:20 |
| xfxf | hmm what irc client are you using? | 04:23 |
| xfxf | i can't find how to do ansi colors | 04:23 |

| xfxf | https://usercontent.irccloud-cdn.com/file/cAavYYW4/20160110_152251.jpg | 04:27 |
| mithro | Is this on the capture or on the output? | 04:27 |
| xfxf | output | 04:28 |
| mithro | xfxf: can you get a high quality photo that doesn't have the jpeg artifacts in it? | 04:29 |
| xfxf | the jpeg artifacts you're seeing are what i am seeing on screen | 04:29 |
| xfxf | it's barely readable | 04:29 |
| xfxf | oh wait | 04:29 |
| xfxf | i see what you mean | 04:29 |
| mithro | xfxf: I need to be able to see the individual pixels around the text | 04:29 |
| xfxf | i'll upload the jpeg as off my phone | 04:29 |

| xfxf | is that any better? | 04:42 |
| CarlFK | You need permission | 04:43 |
| xfxf | i shared it with tim ;) | 04:44 |
| xfxf | but i'll make it public | 04:44 |
| xfxf | try now | 04:44 |
| xfxf | also default zoom looks compressed as hell | 04:44 |
| xfxf | if you zoom in to max it you can make out each pixel | 04:44 |
| CarlFK | xfxf: can you skip the hdmi2usb but also force the source to 720p ? | 04:47 |
| xfxf | the source is 720p | 04:47 |
| xfxf | it's my computer | 04:47 |
| xfxf | and it looks perfectly at the same res hooked directly in | 04:47 |
| CarlFK | huh | 04:47 |
| xfxf | also the monitor i'm using has a nice 1:1 mode where it won't scale up the resolution | 04:47 |
| xfxf | that photo is taken with 1:1 | 04:47 |
| xfxf | so it's absolutely representative of hdmi2usb output | 04:48 |
| xfxf | the screen isn't altering it | 04:48 |
| CarlFK | cuz that looks like software | 04:48 |
| mithro | xfxf: can you take a photo of the same thing hooked up without the HDMI2USB | 04:48 |
| CarlFK | like the video driver or something in that area scaling it | 04:48 |
| xfxf | it's not | 04:49 |
| xfxf | i'm looking at it right now plugged in | 04:49 |
| xfxf | i'll take a photo when my phone is above 5% battery | 04:49 |
| CarlFK | mithro: the encoder at quality 100 should show the same thing, right ? | 04:49 |
| mithro | CarlFK: the encoder isn't involved if you are doing HDMI in -> HDMI out | 04:50 |
| xfxf | mithro: i didn't think it was but to me, the screen looks 100% like it's being jpeg encoded | 04:50 |
| xfxf | i see jpeg like artifacts sometimes | 04:51 |
| CarlFK | mithro: I am thinking it might be interesting to see if the hdmi2usb is getting that same thing | 04:51 |
| mithro | xfxf: It is probably the YUV encoding - but I want to compare with and without pictures first | 04:51 |
| xfxf | ah, colorspace would make sense | 04:53 |
| xfxf | i'll get you a picture as soon as my phone has charged enough to play ball | 04:53 |
| xfxf | i just checked the recorded video - it looks similar, but worse | 04:53 |
| xfxf | i'll see if i can save out a frame | 04:53 |
| xfxf | in positive news, voctomix has been recording perfectly at 30fps with hdmi2usb for 22 hours straight now | 04:53 |
| xfxf | voctocore did something stupid last night though and i no longer can open the UI | 04:54 |
| xfxf | but it's still recording perfectly, with av sync | 04:54 |

| mithro | For the I2C | 07:18 |
| seaLne | yeah | 07:18 |
| mithro | seaLne: you don't need the ADP3303-3V3 I think? The TOFE interface provides 12V and 3V3? | 07:18 |
| seaLne | i'd wondered about that wasn't sure about noise | 07:18 |
| mithro | seaLne: just put some decoupling caps on it | 07:19 |
| seaLne | ok | 07:19 |
| mithro | seaLne: you need 2 x 1V8 converters? | 07:20 |
| seaLne | yeah, datasheet and example layout say to | 07:20 |
| mithro | seaLne: The spare IO pins I'd recommend adding LEDs to them (or atleast a header) | 07:20 |
| mithro | seaLne: you definitely want some power LEDs too | 07:21 |
| mithro | seaLne: otherwise the TOFE connections look fine | 07:21 |
| seaLne | cool, led for each power? or just one for showenig tofe power? | 07:21 |
| mithro | seaLne: we don't have any power LEDs on the current boards and it's a pain | 07:22 |
| mithro | seaLne: One for 12V, one for 3V3 from TOFE | 07:22 |
| mithro | seaLne: I'd also recommend one on the output of your power supplies too | 07:22 |
| seaLne | ok | 07:22 |
| mithro | seaLne: If they are too expensive you just don't populate them - but they arn't :) | 07:22 |
| seaLne | k | 07:23 |
| mithro | seaLne: I'd also recommend adding headers on both sides of your I2C VGA bus | 07:23 |
| mithro | (You want a header with VCC, SCL, SDA, GND) | 07:23 |
| seaLne | ok | 07:24 |
| mithro | I'd also recommend adding headers on the other I2C busses too | 07:24 |
| xfxf | Tim: github is spamming me with hundreds of notifications about your actions on hdmi2usb things, are you seeing that? | 07:29 |
| micolous | xfxf: disable watch | 07:29 |

| seaLne | mithro: should DIFF_CLK_X be broken out or is that just somethig generically for TOFE? | 07:32 |

| CarlFK | that was passed to me via an either pad. i don't know how to use it. | 07:40 |
| xfxf | we're not using a bunch of while loops in a screen session to do this | 07:50 |

| seaLne | mithro: this is what i'm thinking of doing for those pins with 0.1" header that can be jumpered. does it seem reasonable? https://imgur.com/C1CRuDe | 08:46 |

| xfxf | mithro: I think there's a hdmi2usb issue with my laptops | 10:18 |
| xfxf | mithro: is it possible some usb chipsets are crappier? | 10:18 |
| xfxf | mithro: basically, on a desktop i5, i can capture from the hdmi2usb into voctomix no problems, no slowdowns. | 10:18 |
| mithro | xfxf: can you please explain what you think the problem is? | 10:19 |
| xfxf | if i do it on 2 different laptops, the hdmi2usb input eventually slows down to a really slow speed + i have to restart the hdmi2usb capture script | 10:19 |
| mithro | xfxf: yes, some USB chipsets are crappier then others - but that isn't that common | 10:19 |
| xfxf | i just split it up so the core/gui was running on the desktop, and the hdmi2usb input was on the problematic laptop | 10:19 |
| xfxf | and the problem came back | 10:19 |
| xfxf | which is 100% going to bite us in the butt at lca | 10:19 |
| xfxf | the hdmi2usb works perfectly on the desktop | 10:19 |
| xfxf | if i can do anything to debug let me know | 10:19 |
| xfxf | the two laptops are a i5 lenovo, and a asus i7 | 10:20 |
| mithro | xfxf: Have you tried the exact same loop with the Logitech USB webcam? | 10:20 |
| xfxf | both are using intel usb as far as i'm aware | 10:20 |
| mithro | inplace of the HDMI2USB | 10:20 |
| xfxf | no, my webcam isn't working | 10:20 |
| xfxf | i might pull it apart and see why | 10:20 |
| xfxf | i'm fairly confident the issue CarlFK is seeing is exactly what i'm seeing | 10:21 |
| mithro | Basically, if you get the problem with the Logitech USB webcam, it isn't the HDMI2USB fault | 10:21 |

| *** travis-ci has left #timvideos | 10:21 | |
| mithro | xfxf: it's somewhere else in the stack | 10:21 |
| xfxf | would it be useful if i modified the gst-launch line we're using for voctomix and make it just save it out a local file | 10:21 |
| mithro | xfxf: if it goes away, then we need to compare it | 10:21 |
| xfxf | and see if it happens independent of voctomix? | 10:21 |
| mithro | xfxf: no | 10:21 |
| mithro | what is the problem you are seeing? | 10:22 |
| xfxf | sure, let me try and get this webcam working | 10:22 |
| xfxf | after 1.5-2 hours the video slows down to 0.5fps | 10:22 |
| xfxf | the only thing that fixes it is restarting the hdmi2usb gst-launch line | 10:22 |
| xfxf | (there's ANOTHER issue where the voctomix UI slows down - but that's seperate and i've isolated that. this 100% isn't that) | 10:22 |
| xfxf | tldr; hdmi2usb works perfectly on my desktop i5. does not with *everything* else the same on 2x laptops | 10:23 |
| mithro | xfxf: you can test capturing locally if you want | 10:27 |
| xfxf | mithro: if it occurs there, is that useful data to you? | 10:27 |
| mithro | xfxf: sure | 10:31 |
| xfxf | mithro: created ticket for wierd red issue | 11:05 |
| seaLne | mithro: i wasn't too sure what filtering to have on the 3v3. i've added i2c headers and power leds now https://github.com/sealne/HDMI2USB-TOFE-VGA/blob/master/board/TOFE-VGA.pdf | 11:55 |
| tpb | Title: HDMI2USB-TOFE-VGA/TOFE-VGA.pdf at master · sealne/HDMI2USB-TOFE-VGA · GitHub (at github.com) | 11:55 |
| mithro | seaLne: probably the same as that other power supply you had | 11:56 |
| seaLne | ok | 11:57 |
| mithro | seaLne: wp needs a pull up/down resistor for then the jumper is removed | 11:57 |
| seaLne | with another jumper i guess? | 11:58 |
| mithro | seaLne: nah | 11:58 |
| mithro | seaLne: having a little current draw while you program the EEPROM is no problem | 11:59 |
| mithro | seaLne: you haven't got anything connect to the EN pins of the level shifters - is that what you want? | 11:59 |
| seaLne | i think so | 11:59 |
| mithro | I would guess you need to pull it in some direction? | 11:59 |
| seaLne | i was re-reading the data sheet | 11:59 |
| mithro | seaLne: it's an enable pin right? | 12:00 |
| seaLne | it has internal pullups | 12:00 |
| mithro | seaLne: since you have spare IO pins, why not connect them? | 12:01 |
| seaLne | would we ever want to disable i2c? | 12:01 |
| mithro | seaLne: dunno, but better to have the feature and not use it :P | 12:06 |
| mithro | xfxf: any thoughts on what to put here -> https://hdmi2usb.tv/early-adopter | 12:06 |
| seaLne | mithro: i'm not too sure what you were meaning me to do with the eeprom wp pullup? | 12:07 |
| mithro | xfxf / micolous: I've simplified the firmware situation on the website and the repositories | 12:07 |
| xfxf | do you have / will you have a single page of easy to follow instructions to get somebody running with the hdmi2usb? | 12:07 |
| xfxf | because it's a bit of a wade through many pages and ask questions here thing at the moment | 12:07 |
| xfxf | i'm yet to try your prebuilt firmware that said, i'm still building it myself because i know that workflow | 12:08 |
| mithro | xfxf: well - the Opsis boards you just plug in and get a Webcam + Serail port without having to load anything | 12:08 |
| xfxf | will I get the Opsis boards before everybody gets their crowdsourced one? | 12:08 |
| mithro | xfxf: maybe by a day or two | 12:08 |
| xfxf | because i'm happy to do a pretend i know nothing about the device and try setting it up from scratch following supplied instructions | 12:08 |
| xfxf | ah, not much time | 12:09 |
| mithro | xfxf: you should get them this week sometime | 12:09 |
| xfxf | including customs? | 12:09 |
| xfxf | you said GST was payable | 12:09 |
| xfxf | customs can hold shit for weeks... | 12:09 |
| xfxf | usually days, but can be weeks | 12:09 |
| mithro | xfxf: GST payment is normally like a 30 second thing - Fedex give you an invoice, you pay invoice - done | 12:10 |
| xfxf | ah, not my experience, but hopefully that's the case | 12:10 |
| mithro | seaLne: the WP pin should have a resistor pulling to either VCC or GND. When the jumper is connected, you connect WP to the other value | 12:11 |
| mithro | So when you connect the jumper, there will be current running through the pulling resister (as it is now connected between VCC and GND) but it should be a big enough value that it doesn't really matter | 12:26 |
| mithro | (the resistor that is | 12:26 |
| seaLne | mithro: https://imgur.com/WNW5nPu ? | 12:27 |
| tpb | Title: Imgur: The most awesome images on the Internet (at imgur.com) | 12:27 |
| mithro | seaLne: assuming pulling up is putting it in "write protect" mode | 13:05 |
| seaLne | yeah | 13:06 |
| seaLne | i've connected the level shifter EN now as well | 13:07 |
| seaLne | now you can jumper the DIFF_CLK_X to LEDs instead | 13:08 |
| seaLne | mithro: should tofe 3v3 have a diode like the 12v? | 13:10 |
| seaLne | or would that cause to much of a drop | 13:10 |
| mithro | I think that would cause too much of a drop | 13:10 |
| xfxf | mithro: my VGA > HDMI converter i pasted earlier seems to work at 720p fine with the hdmi2usb | 13:11 |
| xfxf | the video is slightly blurry, but it's VGA | 13:11 |
| seaLne | i saw these that might be usable http://cpc.farnell.com/pro-signal/psg03649/vgaaudio-to-hdmi-converter-with/dp/AV21380 | 13:13 |
| tpb | Title: PSG03649 - PRO SIGNAL - VGA And Audio to HDMI Converter With Scaler | CPC UK (at cpc.farnell.com) | 13:13 |
| seaLne | might find someone else selling them | 13:14 |
| seaLne | no idea if they are good though | 13:14 |
| mithro | Fixed 1280 x 720p output resolution !? | 13:16 |
| seaLne | there are others without the scaler but i thought for just now that would be useful? | 13:16 |
| xfxf | mithro: yep, 720p. i could set other resolutions, i got nothing through (assume it's ignoring the EDID data set by the hdmi2usb), but setting it manually worked | 13:17 |
| xfxf | it's not perfect but it's good enough | 13:17 |
| xfxf | VGA only should be a very small % of cases | 13:17 |
| mithro | seaLne: sadly it doesn't look like Farnell Australia stocks them | 13:18 |
| seaLne | yeah cpc is a different catalogue from "normal" farnell | 13:18 |
| mithro | seaLne: so, that schematic is looking pretty good | 13:52 |
| mithro | xfxf: you still up? | 13:55 |
| mithro | seaLne: I also notice we have that open pull request from you about the "make download prebuilt" | 14:07 |
| seaLne | mithro: i think that was superceded by some other thing? | 14:24 |
| seaLne | or rather that work flow was no longer through useful? | 14:24 |
| mithro | seaLne: maybe the mode-switch tool? | 14:24 |
| seaLne | as it still required a lot of the other tools it was only useful for lazy developers while i'd originally thought it might have been for users | 14:26 |
| seaLne | so i think it can probably be forgoten | 14:27 |
| seaLne | mithro: do you think there will be enough interest in tofe-vga to get it "manufactured" or do you think it will just be a low enough volume to place by hand? (this could effect size of passives) | 14:30 |
| mithro | seaLne: I'd go with passives which you can hand solder | 14:32 |
| seaLne | yeah, some will probably have to be a bit small to fit in some places. but it probably makes sense to make the rest larger | 14:33 |
| seaLne | and atleast the first batch would be by hand anyway | 14:34 |
| mithro | the capacitors have to be reasonable large anyway I think? | 14:35 |

| MaZderMind | mithro: i have not yet gotten around to implement this. my plan is brilliant, of course ;) | 23:11 |

| mithro | MaZderMind: Everyone has too many things todo | 23:27 |
| MaZderMind | restarting voctocore once a day avoids the buggest issues | 23:29 |
| MaZderMind | so it's a not-so-important thing currently | 23:29 |
