Good morning! I'm Gerrit. #intro #introductions
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. #theFoundry
Designing the enclosure for my open-source outdoor air quality monitor and trying out various test configurations on the 3D printer. #theFoundry
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: https://www.hardwarethings.org/zine
It's working! I made a solar-powered air quality monitor sending data over LoRa to The Things Network. #theFoundry
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. #theFoundry
I always feel like such a noob when I'm routing PCBs. #theFoundry
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: https://aesthetics.fandom.com/wiki/Solarpunk
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. #theFoundry
@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! 🎉
