I've set up a jitsi terminal on the wall in Sudoroom!

"power saving" mode when the HDMI signal is lost. That means the screen can power down when DPMS puts the monitor to "sleep". It has a webcam that's clearly labeled, and on a hinge so it can easily be aimed down at the floor if people are shy, and it has a Jabra USB speaker/microphone thing which should hopefully provide good speakerphone functionality. I have the computer setup to start firefox, and i have firefox set to open the jitsi page, where permissions are already enabled for webcam/audio. The only remaining need is to automatically wake the monitor from sleep (using "DISPLAY=:0 xset force dpms on") whenever there is anyone else detected in the jitsi "room"

wow, this has progressed a lot! tonight, in the jitsi chat, which is here: https://meet.waag.org/turtlesturtlesturtles matt and me (to the entertainment of everyone passing through sudoroom and working in there) have been chatting and co-hacking, and i've been learning npm/node/react web stuff. basically we installed the jitsi SDK repo and ran it, and then hacked it to go to the meeting room we've been using instead of the default setting - and now we're adding a function to it to automatically control the screen power (screensaver) depending on whether someone is in the "room" or not. we're also sharing a tmux window in the machine (the one controlling the big TV) and teaching each other lots of stuff. And neither of us are physically in the space! It's the most exciting saturday night i've had in a long time! If anyone else is interested in this kind of social hacking, speak up and i'll ping you if it happens again. Or just join the jitsi room (linked above) and leave it open until someone starts talking to you. last night (friday night) we had a bunch of people join the chat!!! including a couple of people who randomly hadn't seen each other in almost 5 years! It was basically a party, including whoever was in sudoroom, and like 6 different people who rolled through the jitsi chat. -jake On Sat, 15 Jan 2022, Jake wrote: into screen at functionality.

yes it's awesome! log in and look at sudoroom anytime here: https://meet.waag.org/turtlesturtlesturtles if it's dark, it probably means nobody is there and the lights are off and the planet is blocking the sunlight, but if you wait no more than 12 hours, the planet will turn and sunlight will stream in again, illuminating the room. Also, hackers will appear and you can talk to them and try to entertain them! Both hackers appearing in person in sudoroom, in view of the telescreen, as well as other hackers connecting to the jitsi room from wherever they may be. what Matty said about the client app is only 90% of the new innovation, the last bit is my contribution; a python web server which allows the custom web app to turn the telescreen on or off, depending on whether people are in the jitsi "room" with it: https://github.com/jerkey/ducks/blob/dpms-control/server.py it's just copied over from a web server to open and close a duck coop door (get it...WEB server because ducks have WEBBED feet) with a few changes to actually turn the monitor power on and off through DPMS. so join the chat and join in the hacking! it's social and fun and safe! -jake On Sun, 16 Jan 2022, ruin mechanic via sudo-discuss wrote: and learning and and above) years! webcam down speaker/microphone else downstream :/ _______________________________________________ sudo-discuss mailing list -- sudo-discuss(a)sudoroom.org To unsubscribe send an email to sudo-discuss-leave(a)sudoroom.org

hey it seems like maybe handleParticipantChanged() only gets called when someone joins or leaves the room... is there a way to call it when we join the room in the first place? Because what if the monitor state isn't what it should be and we join... we won't know to correct the situation until someone joins or leaves? actually i know this seems annoying since we've already hooked into an API event, but presently the DPMS timeout is set to 300 seconds. That means that the screen is supposed to blank if there's no "activity" like moving the mouse around or hitting a key on the keyboard. It seemed to me like Chromium or the jitsi window was disabling that...because I wasn't noticing it blanking even though there was no keyboard/mouse activity...but maybe that's changed, in which case it will blank after 5 minutes even if we've turned it on explicitly (for example when someone joined the room) Should I fix this by disabling the timeout? Then the monitor state will stay the same until it's acted upon by an external force. But then if there's nobody in the jitsi room (which will unfortunately be most of the time) if someone plugs in a keyboard/mouse (they will) and wakes up the screen...it will stay on indefinitely. That's not ideal. I think i'd rather keep the 5-minute timeout, and just get the javascript thing to check every five minutes (and upon startup) whether there are enough people in the room to keep the screen on, in which case it pokes the screen-on it would even be OK to just not tell it to turn off anymore at all, since the timeout would take care of that. This would be good because you can imagine cases where someone leaves the jitsi chat for a few seconds and rejoins, we don't need to power-cycle the monitor's backlight unnecessarily if they're coming right back. What do you think? awesome work by the way! -jake On Sun, 16 Jan 2022, ruin mechanic wrote: and the room. telescreen, as may the door achieved it power the 6 go to _______________________________________________ sudo-discuss mailing list -- sudo-discuss(a)sudoroom.org To unsubscribe send an email to sudo-discuss-leave(a)sudoroom.org
