My wife has a podcast that’s basically a radio show. I’ve built an online radio for it using icecast and ezstream, and I’ve built her a management dashboard where she can enable/disable episodes, add and set up stingers/ads*/whatever else she wants. New episodes get downloaded and added automatically. Front end shows which episode is playing.

* Ads are in universe, not Better Health or whatever.

I’d say it would be a common use case but still never see people host it, a deadman switch sends notifications for you to check in, and if you miss enough of them sends selected contacts notifications and executes scripts

Sist2 (Lightning-fast file system indexer and search tool). I’m not suggesting this is most unique use case, but noone mentioned it. I was mind blown when I became aware of it. I was looking for a way to manage my digital book and document archive for a long time. Tried various book management solution but none had full text search across whole library. Its lighting fast (like instant) you get excerpts with thumbnails and links to the files. Point it to your storage and you will gain extremely efficient way to look at your archives and references. Btw. I was already well organized and structured with my files, but going through it and searching for things I knew were there, was always a bit of a pain.

I have a lot of custom stuff, esp. regarding HomeAssistant integrations. But my favorite “stupid/not stupid if it works” solution is the following:

I have an LG TV and attached Nvidia Shield. The Shield is the only input we ever use on the TV, and since its remote also can turn the TV on/off and control volume, its all we need. Which is pretty neat, only one remote.

Except for image settings (i.e. proper bright picture during the day, different less bright image mode during the night). I don’t want to keep the extra remote on the couch just for that, but unfortunately, these settings are not exposed via HDMI CEC.

They are, however, exposed via a web API on LG TVs. So my utterly stupid solution is this:

• install quick actions app on the shield
• reconfigure Netflix button on the shield remote to open quick actions popup
• add two quick actions, night and day, that curl simple HTTP endpoints on a VM I set up
• on the VM, a simple flask server listens, and then sends the (too complex for the quick actions app) API request to the TV.

(I feel the need to add: the TV is in an isolated subnet and has never once communicated with the internet, and it will damn well die an internet virgin.)

Anyways, this has been working flawlessly for 2+ years! I also have toggles in HA for the same endpoints, but honestly, never use them. It’s so nice to just be able to toggle the image via remote.

I’ve written a Signal bot that listens for messages from my wife and me. It’s for sharing pictures of our daughter with a small list of people that want baby pics. The images we send it get blurred and sent as a preview, with an unblurred version sent as a “view once” image. Each blurred image contains an ID so that recipients can request the images again.

I built myself a ‘new masked email’ workflow. I copy and paste the site url into the form and click create. It generates my random masked email, generates a strong password, prompts me for my keepass password then saves all the things and copies the generated password to the clipboard. Here are some screenshots. I did a test entry to demonstrate for you.

New form.

I type in my KeePass password and I get this screen while the entry is automatically saved to KeePass.

This all runs on an Intel NUC in my office and is accessible over my local network.

I didn’t implement this because it stopped being needed, but a text to print converter for my hearing impaired and non-techie elderly mom. Basically an email gateway running on VPS so if she got an email or text from a family member, a raspberry pi in her bedroom would immediately print out the message on a receipt printer where she would see it. I was going to use a cheap thermal printer but another family member objected (I guess reasonably) to the toxic crap in thermal paper, so I found someone selling a still affordable impact receipt printer on craigslist. Nothing actually happened with this, but I liked the idea.

Another idea I haven’t pursued: something that monitors the movement of local transit (BART trains, and buses) so I can check their ETA’s and locations from a phone browser. There are existing apps and sites for this but they unfortunately suck. They always answer “when will the next bus/train arrive at stop XYZ” which is almost never what I want to know.

What I want is usually either “I’m on the #123 bus RIGHT NOW and want to get off at XYZ, how many more stops do I wait?”, or else “my friend is on BART and just passed station X. When will she get to station Y where I’m supposed to meet her?”. Anyone implementing anything like that, please take it into account. The transit agencies usually have API’s to get the relevant data.

My wife often writes groceries lists using her phones note app, and sends it to me if I’m doing the shopping. Each item in the list is in it’s own line.

I use Nextcloud Notes, I’m pedantic and want to use a markdown checkist for shopping lists (also bad at shopping). I wrote a Matrix bot, or rather added a feature to an existing one, that adds - [ ] in the beginning of each line of a received message and sends the result back. I then copy-paste the response into NC notes.

I setup a simplex alerting bridge so grafana can create lab alerts to a simplex group, messages disappear when alerts are resolved.

Not sure it really counts.

For community radio

A VPS running wireguard.

Four presenters connect in from home.

Using Stream What You Hear to create the live MP3 stream from their mixer.

Played using Zara Radio to the FM transmitter.

It’s pretty reliable.

Same VPS hosts a Rustdesk server.

I selfhost podsync. Even for podcasts that have their own feed, I love getting chapters embedded…

I’ve (with lots of assistance from Claude) created a selfhosted app for managing a beer cellar and or well stocked fridge, which keeps track of drink-by dates, has push reminders to a PWA web app and much more.

I have wireless wyze cameras in my house that are connected to a private network segmented away from internet access.

because of that, it’s impossible for them to retrieve updates. So I wrote a proxy in crystal-lang that can proxy web requests over my private network to the public internet.

this allowed me to pull the new hacked firmware and installed them from github while maintaining network privacy.

a year or so later I began selfhosting gitlab and now I just have a job that pulls a clone there and all the cameras pull from within my networks.
