Sigh I started building my first circuit on a prototype board today and now that's all I wanna do.

Except I have to do dumb stuff like "eat" and "sleep".

Blowing off work tomorrow would be appropriate right?

@ottaross I'm sure I'll post some pics when it's working.

I'm building two boards. First one is a SparkFun RP2040 and two MAX485 modules in transmit mode, second is two more MAX485 modules in receive mode with a 36v->5v regulator. Idea is to pipe two streams of neopixel data across my garage from a tiny x86 machine to where the strands start.

@zrail neat - are the neopixels in linear strings or arrays perhaps?

My decision making process is not coherent.

zrail,
@zrail@hachyderm.io avatar

I have no justification for this largess. I just wanted one or two spares to mess with because I have five in production and sometimes I need to FA to FO. I could have spent $40 on one machine but I chose to spend $160 on 16 machines.

I haven't tested any yet but they all look to be in good physical shape and all appear to have their (incredibly rare) wifi cards. If they all work I can plausibly part out half the wifi cards for what I paid for the lot.

@zrail Have you written up how you use them? Less technical but more practical. Do you have one in your kitchen?

After struggling for too long to get my site up and running on versions of Ruby and Sinatra less than a decade old I decided to explore other options.

As of 5 minutes ago https://www.petekeen.net is generated with https://lume.land (/ht @cadey ) and served with Nginx from the server in my basement.

I tried to make the build and release process as simple as possible without writing any software.

  1. GitHub Actions picks up changes which...

  2. Builds a two stage Docker container. First stage builds the site, second copies the result into nginx:alpine-slim with a cut down config.

  3. Watchtower cycles every 30 seconds on a VM on the basement server. When it sees a new version it pulls and recreates the container.

  4. Nginx running in @flydotio connects to the container via @tailscale

@webology@mastodon.social avatar

@zrail Watchtower has boringly just worked for me for this, too. I set mine to 2 minutes because I'm running a dozen+ websites being polled.

I like your idea about using fly to proxy in. I have used Tailscale's funnels for a few projects, mostly to allow GitHub to access it. I should probably re-think that.

It's so nice to have a parts bin deep enough (and infrastructure developed enough) to just build the things I want to build.

I put some grass seed down but didn't have a sprinkler, so I bought a sprinkler, and then I decided I wanted to hook it up to #HomeAssistant

All I needed to buy was a cheapie in-ground solenoid sprinkler valve, NPT to GHT thread adapters, and a 24VAC transformer. Dug a Z-Wave relay out of the parts bin and wired it up.

#HomeLab

@zrail@hachyderm.io avatar

@webology So you'd have the hose bib connected to the pipe and then branches off for various things?

These valves seem pretty easy to use if your orbit system doesn't do what you want, fwiw: https://www.amazon.com/dp/B01MG1VV2M

They'll hook right onto 3/4" PVC or you can use NPT to GHT thread adapters to hook them to the hose.

They want 24VAC but those transformers are cheap. If you have zwave the Zoos ZEN16 can do three zones and can also be powered from 24VAC.

webology,
@webology@mastodon.social avatar

@zrail I was using https://www.amazon.com/dp/B0B1QWVQPY/ with three hoses connected and one end cap to prevent chaos.

#1 Side + #2 front yard for sprinters, with the #3 being on a spool for flowers. Our only faucet is in the back of the house.

Thanks for the tip. That might work well in the front, so I can run one PVC line with some control over the direction/flow.

I struggle with running power to something that sits on the ground, though. Am I irrational or is this a valid fear?

Just drove about four hours round trip listening to music from my @jellyfin server via @manet and @tailscale.

A++++ worked gr8 would listen again.

ironicbadger,
@ironicbadger@techhub.social avatar

@zrail @jellyfin @manet @tailscale lucky for you. Because there’s a horrendous self destruct sequence at 4.20hrs of listening that were rather hoping will just go away ;) kidding obviously.

zrail, to homelab
@zrail@hachyderm.io avatar

I have a collection of movies and TV shows on my NAS being served by Jellyfin. I have a "Kids" account with access to a subset of this media.

I want to transcode just that subset with specific settings and dump it to external storage. Ideally this would happen whenever I plugged that external storage into the NAS.

Is there an off the shelf solution to this or do I need to roll my own?

@ironicbadger I could not for the life of me figure out tdarr's interface. I'll check out file flows, thanks!

@zrail all the options in this space are overly complicated UI wise imho.

I have a UPS and a couple pieces of network gear in an uninsulated shed. I tried using one of those battery mat thingies but the UPS got a little melty over the winter.

I'd like to keep the UPS above freezing and also be able to run a fan in the summer if it's enclosed. Temps in the shed range from -5F to (probably) 115F. I don't care about the gear as much, it can withstand those temp ranges no problem.

Anyone have any ideas?

@webology @jacob your basement humidifier doesn't have a built-in humidistat? Maybe time to get a new humidifier instead. :)

That said, yes those exist: https://www.amazon.com/KETOTEK-Humidity-Controller-Humidistat-Greenhouse/dp/B0CK1BXNK1/

webology,
@webology@mastodon.social avatar

@zrail @jacob It probably is time to replace it or consider a backup.

It's a dehumidifier and I need to turn it off during certain months of the year. It does have a sensor, but I don't know that it works all that well.

Ok this is maybe a dumb me thing but ever since I migrated to an LXC on it has been losing HACS-downloaded components in restart. I used the same docker-compose file I used when I had it on metal, so I'm very confused.

Have any of my friends used https://forwardemail.net or similar? What do you think?

I'm currently using Fastmail for email routing, both simple wildcard domain forwards and more complicated family routing. Fastmail is fine, but I don't think I'm ever going to convince family to move away from their current email/calendar situation, even if I wanted to move to Google Workspace.

@webology Thanks! Yeah the outgoing SMTP looks pretty useful.

webology,
@webology@mastodon.social avatar

@zrail No problem. You just saved me $10 a year of mostly email bit rot 😄

I'm happy to answer questions if you have them. I did a never minimal post on it years ago when I found it. I might refresh that sooner than later based on the outbound SMTP discovery. https://jefftriplett.com/2021/side-projects-email-is-a-pain/

@ironicbadger a friend of mine put together this project that adds a little twist to the docker tailnet service container idea. It's a single-upstream reverse proxy that also does https termination with tailscale certs.

https://github.com/boinkor-net/tsnsrv

I'm using it in my docker compose stacks now and it works great if you just need to expose a single https port.

I want to get gas usage data into my energy dashboard but my gas meter doesn't expose any kind of IR port or radio signal that I can find. It reports to the gas company daily, however, and I can download a file with daily usage from a non-authenticated link.

HOWEVER that file is only populated sometime after midnight.

Does anyone know how to backdate a sensor reading such that I can get the usage to appear on the previous day?

@homeassistant @homeassistant

@zrail@hachyderm.io avatar

@vcdx71 @homeassistant @homeassistant cool. I picked up an SDR with the intent of trying to pick up the meters but I couldn't get anything. Maybe I'll try again.

Last night I found myself flailing around trying to find a way to bring my electric rates into in a maintainable way.

I settled on querying a static JSON file using jq and the command_line sensor platform: https://www.petekeen.net/static-json-in-home-assistant

I've never been able to bring myself to try but this year feels different.

Do you reach for a familiar language or use it as a chance to try something new?

@zrail I sometimes use it for languages that I’m less skilled at but that do pique my interest.

I have an problem. I don't really want my printer in my office, so I've been keeping it out multipurpose "spare" room (I.e. guest bedroom / workout room / now 3d printer lab).

It's a room that's about 10ftx12ft, has a Murphy bed on one long wall and a rowing machine on the other so there isn't a lot of space for activities.

I need something to put the printer on that is stable while also being mobile so I can scoot it out of the room when we have guests.

zrail,
@zrail@hachyderm.io avatar

I've considered a cheap work table with wheels, a cheaper (2D) printer stand, wire kitchen/storage shelving (the chrome kind), and a planar stand (for woodworking power tools). I'm not confident in the stability of any of that.

Does anyone have any other suggestions? Or votes of confidence in the above?

@zrail i use a UW surplus mobile AV cart https://swapauction.wisc.edu/Listing/Details/14306535/Mobile-Media-Cart

fits my prusa, wings fold out if you need more space, wheeled, has rack mounts so you can mount shelving, power strips, etc.
