I made a lot of music stuff. I hooked up an Arduino to control music tempo with my heart beat [1], made a browser based sequencer for the Korg NTS-1 [2], and a made a web app to generate patches for Teenage Engineering OP-1/OP-Z [3] [1]: https://github.com/schollz/heartbpm [2]: https://schollz.github.io/carp/ [3]: https://op1z.com/

Very cool! Why do you need the Arduino for the heart-tempo? Can't you connect the pulse-sensor directly to the computer?

I made a command-line utility to download books from a Goodreads reading list using Library Genesis: https://github.com/goodlibs/goodlibs (Since libraries have been closed, I used it to download my entire reading list. As I read through the books, if I find one I particularly like, I order a hard copy for delivery from my local neighborhood bookstore to support their business.)

Nice! I've always wanted to download a massive bunch of books and explore them randomly.

I've improved Trivabble, a libre network scrabble game. I built it 3 years ago for my grandmother so she could play with my mother and my sister, living in another area. It was still on, but I had more or less forgotten about it, and then I started to receive thank you emails at the beginning of the lockdown. That prompted be to invest a lot of time on it during the lockdown.

I've seen many days with at least 100 games played during the lockdown, but I haven't set up proper monitoring for this.

Now, people have been contributing to the project since then. Thanks to one of them, there is support for many languages now.

(be gentle, this runs on a cheap VPS)

I thought about making a chess and a checkers version. I made an experimental fork for the latter, and Lichess does the job for the former so I don't plan to make it happen for now. But the code would benefit from this work.

Nothing of any importance. Managed to screw myself up to the point of having constant generalized anxiety, so yeah, things are really working out here.

If you're having a panic attack, run up a flight of stairs, or hop on a bike and do a sprint around the block. Get your heart pumping. It sounds really counter intuitive but it works.

I made a pinhole camera that plots 3D geometries in matplotlib/geopandas[1].

It's still WIP (need to do some minimal ray-casting to deal with depth ambiguity), but the overall goal is to develop a set of minimal camera perspective matrices that can be easily be extended for other uses (i.e I want to use my cameras to calculate geometric view factors as a way of clustering geometric features for statistical learning). Another application I've tested is to use camera and location parameters from the Google Street View camera to project OSM footprint geometries onto street view images.

I resuscitated a 20-year-old-website that was somewhat popular back in the day called storysprawl.com. It's private now, but I have friends join me on Sunday nights to write chapters together - we join Zoom, we write, we read them to each other. It's kind of like choose-your-own-adventure combined with round-robin fiction: Read chapter one, there are choices at the bottom, make a choice. If the next chapter is writte…

Collaborative writing can be great fun - I used to contribute (on occasion) to collaborations on Usenet poetry groups (when taking a break from tweaking the trolls). I wish you all the best for taking this project forward!

I wrote a simple "disaster-ready[1]" site for physical distancing, called the virtual bulletin board system. It is currently in operation in my city but nobody uses it. I tried to get it off the ground but I'm not really sure how to do it. Basically, I think of it as a "geowiki" - a wiki where each entry has an address and a lat/lng associated with it. Here's a screenshot: https://i.imgur.com/RiCiuDi.png I went on th…

Yes, I think some pulse sensors can be! The one I got is specifically for Arduino / Raspberry Pi / etc. [1]

I'll shoot you an email, since you've got your email in your profile :)
