Our car has wifi so you can connect to it and start the heat/ac. It doesn't have 5g/4g just no data wifi so you have to be within ~20 feet to warm it up. The app sucks also, along with connecting to its wifi.

Alexa "Warm Up The Car" -> Home Assistant -> trigger an android phone to run a touch script on the phone to run the stupid app and warm up the car -> then report back it did it correctly.

It still fucking works after 5 years and I refuse to even touch the damn thing, as it's way way too handy when it's cold out.

Future project: I have chickens. They lay eggs. I have cameras. I want to know which hen lays how many eggs. Solution? AI image recognition of the hens (who is who) and if they have laid an egg. Any inputs welcome.

I suppose my most well known one is a recreation of the BBC's Ceefax service (https://www.nathanmediaservices.co.uk/ceefax/) - I wrote a program which scrapes the BBC and various other sources for data and turns it into old-style teletext pages. All hosted from my rack in the attic. Not very exotic but still.

When I lived off grid, I wrote an energy production measurement application. With both hydroelectric and solar going through a 1990s inverter, it was something. Nowadays these are off the shelf for suburban yuppies, but for my DYI-everything homestead, only DIY would do. Measurement was via shunts. I put it online over satellite internet and could watch my production and static consumption from work.

The industry I work in has many many companies. For whatever reason they all seem to use a very similar website template. Job openings are almost always listed on their webpage. Almost always its a plugin from workday or whatever their HR software is. Years ago I noticed that job listings were almost always published to their websites before they appeared on major job sites like linkedin.

I used a business to business website that lists every single company in this industry by location and has a link for each to generate a list of companys and URLS. I monitor this for changes with changedetection.io

​

Then changedetection.io + company list and their job posting URLS that look like this company.com/careers/join-us/?_sft_job_posting_category=technical

​

So I now have about 800 companies that I am able to monitor for job leads and get notified via NTFY with company, job title and job description.

​

Its turned off currently cause I am actively employed, but when I was looking about a year ago I had it running hourly and if I look again I will indeed use it

I have kubernetes cluster running a vanilla warcraft server full of computer controlled bots that play in the world while I'm offline, just chuggs away all day then sometimes I log in and see how the bots are doing and play a little.

I have two! The first is exotic purpose, the second is just tightly integrated so much that it might be only useful to me.

Smashcam

I live on a busy corner, in an otherwise slow and sleepy town right outside the city line. I live between a lot of town services on one side (fire house, library, athletic fields, town hall) and the elementary school on the other side. Pedestrian traffic is very high, the amount of children crossing is very high, bicycles abounds, and the cross street between them is decently high traffic.

So I see a decent amount of car accidents on my corner. 30mph limits on both streets so usually not catastrophic, you might be driving away instead of towed. But the repairs will be substantial on most of these. To provide an objective reality-as-a-service, I set up a camera high up in the eaves of my roof pointed right at the intersection. I've sent the police enough clips that they know where to archive my emails for evidence by routine. I've started training a model to detect car crash noises (and honks) to cut and save the clips automatically. It's not reliable enough yet, but this could become a reasonable pipeline:

Car crash audio detected ->
Notification "Possible crash, do you want to review the footage and send to the po-po?" ->
manual human review to make sure we're not sending false positives ->
hit send ->
email with clip constructed and sent

Photos

This is not exotic in terms of its purpose. Lots or people have self-hosted photo sites (heres a whole chart of them all!)

But none of them integrated with my foss RAW editor darktable.

So I built my own photo site alternative that parses the darktable edit files and DB.

So now on the web, I can see the ☆ ratings I gave the photos in my editor. The tags and labels, etc. I parse the RAW files to show the focus boxes that the cameras write in the metadata when they took the picture, the facial recognition bounding boxes, etc.

And it shows the edit history stack and all the edits from my RAW editor. And of course, it has the left-right swiper to show before/after the photo edits. I can export any size, and it calls out to darktable with command-line control to export with the given edit stack to make the JPG of whatever size I'm requesting.

So yes, alternatives exist. Mine is simply very specialized to a particular editor program. I don't believe I made the repo public, so as far as I know, I (and my family) are the only ones using it. It's probably more featureful than things I have released.

I too have a chicken cam, but no image recognition at this point. However, I have used it to discover that an opossum was breaking in and eating the eggs.

Other than that, the most unique things I have cobbled together are probably these:
- I work from home, so I created an automation using Home Assistant to tie into the Webex API to determine if I'm on a call or busy and, if so, turn on my Do Not Disturb light so that people don't just barge into my office.
- A script my son can run from my OliveTin dashboard to update our Minecraft server (docker container).
- Another script I can run from my OliveTin dashboard to log into my firewall and disable/enable my son's internet.
-- Both of these scripts notify me when they've been run via ntfy.

0815: Tell me you are German without telling me you are German :D

I self hosted searxng, but the problem is after I was done I realised that defeats most of the privacy benefits of searxng: If I'm the only one using it, then I might as well just be using the search engines themselves directly.

So now I also have firefox running in a docker container, searching random junk on searxng every couple of minutes.

How about a selfhostable trashmail solution

I don’t know how exotic hosting a SIEM and EDR (Elastic Security) solution for self hosting ist but I do that. Complete with custom alerts and all. Additionally I use Wazuh for vulnerability management and integrity monitoring on my assets. Also I run a SOAR-like script that enriches my alerts with other SIEM and external Threat Intel data.

Using the matrix protocol to let users on Signal talk to ppl on WhatsApp and combined discord telegram etc, I think i made chat apps more like email, interoperability between chat apps are the best.

Spank me and tell me you host your own email.

I have an automation that is triggered by a door open/close sensor that I have attached to the flushing arm in my toilet with a custom made 3d printed mount for the sensor, which triggers a script on the server which connects to the chromecast speaker in the bathroom and plays the final fantasy 7 battle victory theme whenever someone flushes the toilet. It is perhaps my favorite part of my home.

Does hosting Stash count?

I've recently did something that made my friend go "why the fuck would you even need that?"

I've recently discovered that I can't neither VPN into my VPS nor my home network from my college. Both OpenVPN and wireguard were not working. So, to fix that, I'm running a shadowsocks proxy, which is behind an nginx reverse proxy, through which I connect to my services.

Now, I haven't tested it with my college network yet, but based on other similar reddit posts I've read, it should theoretically work.

Well we all need a 100G capable firewall sometimes

In 2016 purchased and jailbroke 20 iPhone 4, and later upgraded to 30 iPhone 5s on iOS 9.3
I wrote a custom theos tweak which injected an HTTP server into Snapchat.
A raspberry pi was running an nginx server as a load balancer across the 30 iPhones.
I developed an Android app called "Casper", which was a 3rd party Snapchat client. It sent http requests to my load balancer server to fetch signed security tokens from a random iPhone, which spoofed that it was the official Snapchat app.
The Snapchat APIs believed my app was the real app, so it could download and view snaps without the sender knowing it was even opened.
Self hosted an iPhone farm :)
Here's a link to my tweet with photos and videos of the setup for anyone interested!

I wanted to know what the airquality was outside my house, but this was hard as multiple houses here use woodstoves, so i needed to compare the quality of air over multiple points to have a proper baseline.

In short, i now run a virtual m2m lora-wan provider for 5 sensors around my town that feed into homeassistant using mqtt, all sensors are battery powered with solarpanels and powered by esp32's.

Mine is a bit exotic I guess. I use Terraform to manage my home lab. I tried all of the docker update solutions out there and they'd always make my Terraform out of sync. So I built my own solution that interacts with an orchestrator, a backend and a front-end.

I use Terraform to create flows for each service. Then the flows interact with the backend to manage the actual updates. The frontend is there to let me see the latest change log of each project before I update.

For my next project I want to set up an oil tank monitor for our heating. Then I can use Prometheus and Grafana to monitor usage. From there I can start making predictions and so on

I host two exotic solutions beside all other.

Restreamer https://github.com/datarhei/restreamer Complete stack to stream on each plateform without congesting my home network.

Rustdesk https://github.com/rustdesk/rustdesk-server Teamviewer like, very stable and as powerfull as I need.

10 years ago I had a problem: I burn wood to heat the house. The problem was that many times I had something else to do and couldn’t wait for the fire to go out and close the hatch that lets air in the boiler. If the hatch is left open the air goes thru the boiler and cools it down quicker.

The solution: I installed a raspberry pi with a usb cd drive. From the cd drive I tied a fishing line via the adjusting arm to the hatch. When the cd drive opens the hatch closes. I then host a website on the raspberry where I can push for example on ”Close the hatch after one hour” and it would do it.

It was a temporary solution and I have had parts for a better arduino solution for years, but here we are 10 years later.

I’m up for the chicken challenge, dad wants to have chickens, we live too far apart. It’s reusable, plus now you can know which chickens will go to nuggets and which give you omelette

2 years ago , when our 1st child been born, my wife was super stressed about how to raise her. Especially about sleep and feeding times.
I installed Baby monitor on docker and it provided huge help with her stress and with the baby ofc.
Simple but people were like WTF for sure

I'm not hosting anything exotic right now, but in the past, before the -arrs existed, back in the 2000s:

• Linux computers in every room, all PXE booted thin clients I crafted myself from a pallete of off-lease computers
• A custom RSS feed to rtorrent to a MythTV setup that migrated video as you walked between rooms.

The first one was actually useful. The second one was more of a novelty I'd show to visitors.
