March has been productive. We left off last time with a major decision to change out a key component, the microcontroller that handles all of our sensor IO and power management. We’ve had our heads down for the last couple of weeks working on that and a few other things. tl;dr: New mainboard prototypes have… Continue reading Forward March
Deshittifying the Internet of Things starts with me.
What was once a promise of technology to allow us to automate and analyze the environments in our physical spaces is now a heap of broken ideas and broken products. Technology products have been deployed en masse, our personal data collected and sold without our consent, and then abandoned as soon as companies strip mined… Continue reading Deshittifying the Internet of Things starts with me.
