After two years of teaching Haskell to highschoolers, I will complete my notes and release them as a proper web book. While working on content I also wrote (in Haskell ofc) a compiler for custom markup (something like Pandoc). The book will defiantly not go deep as some other books, but I hope it will be the best resource on Serbian for starting with Haskell. Also, now when I have my dream tool for publishing, I am t…

This is so cool. Is there somewhere we can subscribe to follow the development of the book?

I'm going to try my hand at an open source smart home. It'll hopefully start with a low-power home server for a e-book library and plex server, and ideally blossom into stuff like smart lighting that looks 'bioluminescent' at night, voice control and scheduling for blinds, privacy windows - and self regulation of air quality and heating/electricity.

It's all very doable, but i've never had the time (or made the time), so here's hoping it's this year.

A blog about aircraft ice protection technology in the years 1919 to 1958, the era of the National Advisory Committee for Aeronautics (a predecessor to NASA). https://icinganalysis.github.io/index.html

Might have to have a read of that - reportedly my grandfather worked on antifreeze solutions at the NPL in London during WWII. Be interesting to see if any of his work is referenced.

I want to disrupt the toaster industry. For way too long I've been getting inconsistently toasted toast out of my toaster. My idea is to introduce cameras into the toaster that are used to recognize when the perfect amount of toasting has been applied. It is a way better approach than just using a timer. I have a few problems to solve...

I'd recommend you have a read about the "Sunbeam Radiant Toaster" first released in 1948 [0]!

I want to build a digital / smart foosball table with features like * automated goal detection * trigger things like lighten up the field on specific events (e.g. a goal) * build a league backend / frontend and player management * allow players to "login" via NFC on the table itself There are a lot of ideas and questions right now. I pitched the idea to my employer to make it a continous "hackathon" for the employees…

Maybe with computer vision it could be a simple app on a phone and work for any table (after some calibration)?

Yup already thought about that but IMO it's much more work and prone to errors compared to just installing some sensors. Want to get that running ASAP and after that we can look into CV options. Already found a project [0] that tried to accomplish that with OpenCV but it seems it's abandoned.

This looks amazing, I'll have to get my hands on one! Thank you

If you can track the ball reliably like the guy from Stuff Made Here does on some of his projects it would maybe be a first step? Anyway this sounds like a super fun project! Good luck!

There must be a strong correlation between the surface temperature of the bread, the time it stays at that temp, and the level of toasting? Maybe an infrared thermostat that would report the surface temperature of the bread would work?

Yes for sure, although I am interested in using something like OpenCV along with some feedback mechanism to turn the individual wires of the element up or down depending on the progress. Surface temperature would be a good average but that may not give toast that's consistently toasted to the same amount across its surface.

I'm helping my Chinese-teaching girlfriend expand her online teaching business. She has zero business background and zero tech background, but even then still managed to land some consistent students last year.

This year I'm using my product development/tech background to help her make a logo, brand guidelines, set up landing pages for her Chinese teaching programs, setup CRMs to track potential student leads, help her write a sales script, etc. It's lots of fun!
