I reviewed a product on Amazon today, and when I was done the next screen said "Review six more products and we'll tell you a joke!"

You already have, my dear.

Turns out polyethylene tubing isn’t so great of a diffusion solution if there is thermal variation. Gonna need to source some squishy silicone tubing instead.

I was wondering what would happen if you played Newton Wars (aka Gravitational Combat), but had a full visualization showing you which target/planet you would hit when shooting in that direction with that force!

So I wrote a #glsl shader to figure that out, and it's really pretty!

This is how it works: If you hover over a red pixel in the diagram, you can be sure you'll hit the red planet! The lightness is how soon you'll hit it.

I made a Soma FM integration for Music Assistant, which was merged into their beta release today. It's a small thing but sparks joy for me, much like Soma FM itself https://github.com/music-assistant/server/pull/2981

I need to announce the Holy Grail of multi-room music streaming is at hand.

Hardware: ESP32+DAC modules, available with line-out or speaker amplifiers, starting below $20 each https://github.com/sonocotta/esp32-audio-dock

ESPHome YAML calling in a PR that implements the Sendspin protocol: https://github.com/esphome/esphome/pull/12284

Noticing a trend of open-source projects with big spec documents, then incomprehensibly complex implementation with obvious architectural issues, and developers who don't know how to fix their 60% working code, or basic concepts like the dangers of dynamic allocation on embedded devices or thread safety. Oh, and file somewhere in the repository with instructions for Claude.

I made a $600 purchase and then cancelled it.

Was going to trash my Orbi Wifi 6 mesh setup because it recently it completely falls apart if anything reboots. Spent dozens of hours on this.

Turns out that Netgear hasn't fixed a problem they've known about for at least a year: their DHCP server is garbage. If you have like 30+ devices, it can't handle those concurrent requests. Breaks the satellite routing too.

I set up a Pi 3 with dnsmasq, everything works perfectly, cancelled the order.
