90s.dev. Well, kind of. I've been working a ton on some variations and ports of it over the last couple months, but the problem is that I need funding. So my plan is to setup github sponsors, where for each project people want me to work on, they can donate any amount, and for each $25, I'll work one hour on that project. It'll have a few related projects that all come from a unified vision I have for 90s.dev -- to b…

Wow, as soon as I post, my comment is second to the bottom.

I'm working on an app[0] that makes hosting temporary PDF forms simple, without needing an account or payment. You simply add input fields over any static PDF and publish it to get a link which you can send to other people who may need to fill the form.

The form stays online for 30 days. To keep the forms online for longer, I will be offering paid plans.

My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and grind them in its propellers.

Our target platform is a 40 grams tinywhoop so it’s safe to fly everywhere and makes almost no noise :). A Roomba for mosquitoes!

The main plus compared to traditional systems is that a drone can cover an enormous surface in a short time compared to static systems or man-portable insecticide spraying. Our goal is to be competitive with ITNs against Malaria.

Still on a sabbatical building things I enjoy, but it's summer here so have also spent much time in my hammock with cold beers.

Most effort on https://wheretodrink.beer, collecting and cataloging craft beer venues from around the world. No ambition of being exhaustive, but aiming for a curated and substantial list. Since last month I've added a couple of minor things like maps and "where to go next" sections for each venue.

I'm debating whether or not I should add user accounts, and let people maintain venue bucket lists, venue endorsements. Also planning to reach out to the venues and ask if they agree to monthly or quarterly one-click information verification emails from us.

Other projects that receive less love are:

- https://drnk.beer, a small side project offering beer-related linkpages, and @handles for Bluesky (AT Protocol)

- https://misplacy.com, just a dumb and wrong AI landing page for now but was thinking to work towards a drop-in solution for SMBs around lost/found management.

- A platform for helping voluntary associations with repetitive administrative tasks (non-english so not linking. Trying to rank the pain points currently)

- A platform for structuring national soccer club history (initial brain dump idea phase)

- A platform for structuring writing prompts and collaborative fiction writing (initial brain dump / mockups)

For the next month or so I think I need to prioritize what to focus on after summer

Always interesting to see what others are building and doing. So thanks for sharing!

I've been pretty frustrated with my 3d print quality, decided to make my self an esp32 based heater control board. It connects to wifi and is based on esphome so you can automate it via home assistant. The prototype worked well enough so designing an integrated pcb and in the process of ordering it on JlCPCB

Ha so cool, would love one for in my bedroom ;-)

I know of a Dutch company doing something similar. Focusses on pest detecting/mitigation in greenhouses atm: https://www.pats-drones.com/

I'm working on this programming language that compiles to Go. The goal is to have it behave like typescript for Go, where any Go program would compile out of the box, but then you can use the new syntax. Featuring: built-in Set/Enum/Tuple/lambda/"error propagation operators" It also have a working LSP server and generates a sourcemap, so when you get a runtime stacktrace, it gives you the original line in your .agl f…

I like the bang operator for propagating errors. Shame to lose multiple returns though
