xfxfCarlFK: i hope you're joking about the chewing gum :)  at least a hot glue gun if you're wanting to dodgy it00:10
xfxftis what i used for my atlys case00:10
CarlFKxfxf: i want to mark where to drill00:13
CarlFKbut I don't have gum, so I may use ... vegemite?00:13
xfxfvegemite sadly isn't the answer to everything00:41
shenki /kick xfxf blasphemy!01:07

mithroCarlFK: I have documents which show the mechanical stuff of an Atlys03:32
CarlFKmithro: next day or two will be handy03:32
CarlFKmithro: I pulled apart a 10/100 rack mount switch has a nice little power supply.  prolly 5v somewhere :p03:33
mithroCarlFK: if you connect something other then 5V to the Atlys you will have a dead atlys03:35
CarlFKyeah, I'll be at ps1 and get some expert advice before I blow it up03:36
thaytanif only there were ways to measure voltages before connecting them :(03:41
JoelwMmm, tingly tongue03:55
xfxfCarlFK: i ponder whether you could use a PoE switch to power devices04:17
CarlFKxfxf: I thought about that, but I think that only makes sense if there is wall power handy04:18
xfxfoh, part of your plan is to battery power everything?04:18
CarlFKdoesn't make sense04:18
CarlFKthe board will be near other things that need power too04:19
CarlFKCamera, presenter's laptop, PA system...04:19
CarlFKas long as we are running power and hooking up power boards, poe isn't going to matter04:20
xfxfwell, more that you could use a PoE splitter to feed the front devices with power04:24
xfxfand run a single ethernet cable from front > back04:25
xfxfthe only caveat there is the ingest machine for the hdmi2usb, but that could potentially be something that takes <20W04:25
tpbTitle: gst-omx: rpi: Add MJPEG decoder (at
xfxfinteresting, that looks like there's a hardware MJPEG decoder in the rpi04:26
xfxfsupported by gst04:26
*** ssk1328 has joined #timvideos04:27
xfxfCarlFK: i've also been pondering something like a boundary mic that plugs into the device at the front, and some sw to manage volume appropriately04:28
xfxfso you unpack the box at the front, pull out the boundary mic with a few metres of cable on it and place it on an appropriate flat surface near the speaker04:28
xfxfmay be 'good enough' for small rooms04:28
xfxfboundary mics are commonly used in VC rooms anyway04:29
mithroxfxf: I think we just want box we blonk down on the podium, the boundary mic could be mounted in the top of that?04:29
xfxfmithro: you want it directly on a table - the way they work is the device they sit on effectively becomes an entire mic04:29
xfxfyou'd get much worse results on it being on a box04:30
xfxfagain, might be OK, assuming this is designed for LUG's and such, not fully blown conferences04:30
xfxfi would strongly suggest there are several different targets04:30
xfxfi.e. conference versus small event04:30
CarlFKalso I want the closed up box to be somewhat rugged04:30
mithroCarlFK: yes04:30
xfxfmithro: i'm intending on trying the above for my local python/django LUG in the next couple of weeks04:31
xfxfit appears i'm also working on trying to simplify a kit independently too04:31
xfxfi want to be able to give some stuff to the local group to try recording without me there04:31
xfxfbut need to prototype the setup + prove it works first04:32
mithroxfxf: so, I should be doing other things now - but I wanted to say the big problem with the "kits" is that they are "kits". If inventorying things was "there are two boxes, and two cables" then things would be much simpler04:32
xfxfyeah i get that, don't disagree there04:32
xfxfi still think this is part of a bigger set of complicated problems though04:33
xfxfbut this is a bigger discussion, i too should be doing other things now :)04:33
*** Guest50991 is now known as aps04:33
mithroxfxf: I think anything more than about 5 "parts" for a room is too much04:34
xfxfya, but i still think there are two distinct targets here04:35
xfxfone self contained kit which works on its own without interfacing to existing room PA04:35
xfxfand the other for conferences which by definition will be more complex due to every venue being different04:35
xfxfthe latter can be automated/simplified more, but that's a much bigger problem to solve then standardising kits04:35
mithroxfxf: so, that gives you - "box at podium", "box at camera location", power cable, networking cable, microphone04:35
xfxfi also wanted to talk to you about the implications of having a 'closed' box too at some point04:36
mithroxfxf: What is the one sentance summary?04:37
xfxfmore that there are some incompatibilities between us trying to intice more people into this project to hack on things, and having a 'closed' box people aren't allowed to pull apart04:37
CarlFKI want to make a box and see how much I want to pull it apart ;)04:41
mithroxfxf: My thought is, by having a box that people can start getting results from without having to understand everything is a good way to start getting involved. It also makes it easier to ship people kits for temporary periods so they don't need to buy stuff.04:42

CarlFKMy thought is, hooking stuff up on site bothers me ;)04:57

mithroDammit CarlFK, why can't your country get its act together and use meters like everyone else?05:16
CarlFKI wish that too05:17
mithroAnd why doesn't monoprice have colored DisplayPort cables? :(05:18
*** shenki_ is now known as shenki05:37
mithroI think I'm going to have to get the spray paint out05:43
mithroCarlFK / xfxf: Do you know if we had any of at the hackfest?05:44
CarlFKmithro: doesn't look familiar.05:46
mithroCarlFK: would you mind getting one and testing it with your Opsis board?05:46
CarlFKmithro: sure.05:48
CarlFKim off to bed - see ya tomorrow05:49
*** ssk1328 has quit IRC05:49
xfxfmithro: no, didn't have one05:51
mithroBertl: the HDMI IC you are using to do the LVDS to HDMI conversion (and equalization) - do you have the "reverse" version?05:51
