Their upgrade scripts for on the rails installs have gotten a lot better recently, especially in the last year. But then last upgrade they fucked it all up and made a series of database commands mandatory for the warnings to go away. Uggghhhh.
Likely. The coils only job is to ignite the lamp by whacking it with high voltage to strip some barium elections off the coil to induce plasma and therefore electrical flow. The plasma then excites the phosphorus to make light. After that the coils could just be stubs of wire so long as current keeps flowing through the excited plasma. If you did it inductively it would achieve the same means but I don’t think the plasma would be as dense so the lamp not as bright. My theory anyways.
Wild to see this posted. I worked for the guy that invented this at Sylvania, I have a bunch of photos of the early prototypes. They never figured out how to commercialize it and in the process of trying to manufacturer it in China the manufacturer stole the IP and started making them under their own brand and stole the market. They were called Icetron lamps. I worked in their R&D facilities and domestic manufacturing sites in the early 2000s.
I love this community, I used to rant about efficiency all the the time on reddits self hosting community and everyone thought I was insane. If the damn thing is going to run 24/7 for 5+ years then put a little thought into its power usage!
I personally love old Dell optiplex micros on eBay. Cheap, plentiful laptop hardware in a cute little box which allows modest upgrades. My primary server in a full sized case is just a laptop CPU, Ryzen 5600g. It brings me joy that my network has four servers and still is under 75w idle for everything including networking gear.
No gpio but old centrino laptops make excellent low power servers. My primary server was a first gen centrino from 2011 up until recently and I think it only used 12w idle after putting a SSD in there. Had it’s own UPS built in.
I migrated from WordPress to Grav and love it. If you know markdown Grav is easy, efficient and FAST.
I guess remembering grade school order of operation means you’re a guinus now? Bar has gotten pretty low…
I went a little crazy and setup my own wireguard VPN network, all the remote hosts connect to the VPN and the primary server connects to each of them and pushes backups. Because I use btrfs and lots of snapshots I use btrbk, annoying to setup but now my hourly snapshots get pushed everywhere, minimal bandwidth and it flawlessly has worked for years.
I do this except the offline copies are raspberry pis, they grab an update then turn their network card off and go black for about a month. Randomly they turn on the network card, pull a fresh copy and go black again. Safe from randomware and automatic.
I have a trailer (workshop) with solar power, batteries, a raspberry pi controlling everything and a cellular hot spot. It pumps all the solar, battery information and light controls over MQTT and home assistant over cellular. So yes its possible, what do you want to do?
Shit I thought I was so damn novel. Blast you.
I’ve owned and deployed a lot of pi, every model, and in my experience when I have similar instability as you described its related to the sdcard. Either the sdcard itself or the tray soldered to the pi. I had one pi that would corrupt the sdcard without fail after 2 months and I played with bending the sdcard metal tray inward a little to help press the card better into the contacts and the problem went away. Try fiddling with the sdcard holder or different sdcards.
I host it on the host that runs the script and proxy it. I have one mission critial pi that is my uptime bot, pi hole and backup VPN if my elaborate server falls on its face. But you could easily use docker volumes too, and have the script push to that folder.
Yep, here is the yaml but redacted

Similar, but more fancy, I have a bash script that runs every 15 minutes and ingests a config file. The config file has a super simple CSV format of every service I have. It checks that all the services are operational and generates an HTML file from it. If any services are down the HTML will show its down, otherwise its just a helpful link.
I just made a landing page in HASS, if you’re already running three instances could you make a page in one?
Older speakers like that use always on transformers, constantly wasting energy to keep the core energized. You’re correct those cannot be made any more, they must use efficient switch mode supplies.
+1 on this idea, going to toss in my recommendation for an AMD 5600g second hand. Its basically a laptop CPU with built in GPU that handles my jellyfin transcoding without issue and has a super low idle power rating if you pair it with a quality, small PSU.
Thats friggin bananas. Do you live somewhere with lots of hydro power? Your cost is less than 1/3 mine…
I work for an un-named company that makes stuff that has google assistant on them. Initially we put hardware mutes and piped the microphones to physical hardware that monitored for wake up words locally and would then start piping the microphone data to the mother ship once it was heard. Google told us to stop that, only way to certify the product as compatible with Google Assistant was to pipe the raw microphone data to the mother ship 24/7. That was 5 years ago and I removed all devices from my house.
