Good morning! I'm Gerrit.

I'm into decentralized networks, open source hardware, modular design, distributed manufacturing, appropriate technology and solarpunk.

I spend most of my time liberating data from diabetes devices like insulin pumps and blood glucose meters, writing open-source software for tidepool.org.

I would like to spend more time growing food and building hardware to support that, and I hope to find inspiration here in the Merveilles.town community.

Got a fancy new Japanese crimping tool to make some JST PH 2.0 connectors.

Being able to export your PCB as a 3D model does make designing the enclosure so much easier.

Designing the enclosure for my open-source outdoor air quality monitor and trying out various test configurations on the 3D printer.

Just open-sourced the code, schematic, PCB layout and Bill of Materials for the air quality monitor I'm working on.

Just got Outside Influence, a new e-zine made by Hardware Things, the best newsletter about hardware tech on the African continent: hardwarethings.org/zine

It's working! I made a solar-powered air quality monitor sending data over LoRa to The Things Network.

We recently moved to a house in the marina. So while I don't have a sailboat, I can at least live vicariously through the boats coming and going in the harbour.

Just sent my first PCB Assembly order in to JLCPCB. Why am I so nervous? 😅

Getting closer to something that I can actually send off to the fab.

Sniffing some I2C packets to figure out why this battery fuel gauge chip I'm trying to talk to is not responding.

This $10 logic analyzer is one of the best debugging tools I've ever bought.

Discovered the Aesthetics Wiki through the Dense Discovery newsletter this morning: aesthetics.fandom.com/wiki/Sol

Typing out sample code from a magazine like it's 1995, except in 2021 it's to play music on a Raspberry Pi Pico with only a small speaker and a resistor as external components.

@PINE64 Apologies if this has been asked many times already, but is the Nutcracker Challenge still open, i.e., are there still EVBs available?

@stevelord Oh snap, your Plan 9 post is trending at number 2 on Hacker News right now!

It's the middle of winter, but I've got rainbow chard, broccoli and lots of tomatoes growing in my hydroponic garden.

"Currently, less than 0.1% of hydrogen produced in Europe is green, produced via the electrolysis of water, with the electricity used in the process coming from renewable sources like wind and solar. More than 90% is grey hydrogen, made using fossil fuels like oil and coal, which emit CO2. This means that at a moment of climate emergency, public investment in hydrogen will essentially keep funding the same old pollutants."

Compiled Espruino firmware from source and flashed it to a Pixl.js board without any problems. I'm on a roll tonight! 🕺

Just compiled wxWidgets v3.0.5 from source to fix the double window border bug that affects KiCad on ElementaryOS, and it worked first time! 🎉
