It's for controlling DMX colored lights over network. It takes UDP packets (and later Websocket messages) and turns them into DMX protocol packets which get sent over USB serial adapter to the DMX wire. It's a rewrite of a previous node.js version which had bitrotted.
I think I made the MVP in about 7 hours during one saturday afternoon. Finishing it up took a few weeks more of evenings.
Threw together a toothbrush timer for my kids. Just used the svelte repl: https://svelte.dev/repl/5a7f676868044bbba2ff3c7a64062066?ver... On mobile you’ll need to kit the “output” button

I've only tweaked it a bit since then, after sharing it and getting some feedback from others who found it useful.
So, if you were in NYC in January and wanted to find out the closest location that was at least 72 degrees, it would spit out locations that met that criteria.
(There was also a companion app, "Take Me Cooler," that did the reverse.)
Required a one-time download of ZIP/coordinate data and daily downloads from a weather API. Figured out how to calculate the distances, and most of the rest was just stitching it all together.
The reason it only gives you one random thing a day is cause I didn’t wanna try “re-roll” the pattern I was gonna practice to give me something easier.
Started in quotes because my contribution was combining an existing project that was about to fail due to capacity issues with the infinite botnet of AWS spot instances and the power of Hacker News.
It's more than a decade ago now, but I think it's a good example of a project with a simple goal that enabled people to get involved and feel like they were doing something useful.

I needed to test the impact of a product we were developing on the air temperature distribution of a room (it really is warmer at the ceiling) so over the course of a weekend I strung up 27 OneWire temperature sensors in 9 strings of 3 from the ceiling of my living room and wrote a script running on an mBed microcontroller (like an Arduino) that would poll the OneWire bus every 30 seconds and send the responses back…
I'm curious if a very low resolution thermal imager such as Grideye could act in a similar fashion if you scanned the room using servos (https://www.adafruit.com/product/3538 is an example of a breakout board). Not sure of the accuracy though of such sensors for measuring temperature.
Edit: Just noticed they have "an accuracy of +- 2.5°C" so not good enough I guess, whereas ds18b20 claims 0.5C.
Ludum Dare was particularly good fun in its early years (early-mid 2000s), when it was a fairly small community, when people were coding from-scratch, before Unity became an option and the event grew into something a lot bigger.
Game jam coding is different to 'real' game dev, as the time pressure encurages you to just hack away freely and creatively, not spend too much time thinking about building reusable systems or tools, and you can discard the codebase at the end of the weekend.
These days, small functional 3D printing projects can be quite satisfying. Going from a sketch to a simple CAD model to a first draft print, iterating the design a couple of times, and ending up with a simple-but-useful physical object, learning a bit more Fusion 360 in the process.
