hobzcalvin··on The Color of White Light
I wanted to like this, but the “housewife” comments about sewing buttons and makeup are pretty awful. If we want an inclusive community, this sexist bullshit is not acceptable.

It’s a bummer—I’m fascinated by color theory like this.

hobzcalvin··on Ask HN: What Are You Working On? (June 2025)
https://hobzcalvin.github.io/blumon/editor

Node based visual editor for 2D LED patterns over BLE. Web/iOS/Android app to ESP32, works with most addressable LEDs. It’s like TouchDesigner x WLED x PixelBlaze, but Bluetooth so you don’t need annoying wifi setup. And hopefully you can make much more interesting patterns without touching any code.

Eventually the ESP32 devices will save all the patterns they’ve seen and share them with apps that connect to them. So there’s a pattern ecosystem, like Electric Sheep.

Still rough and in progress (and constantly deploying so it may break for you )

I'm working on a project, definitely less far along, that's open-source and uses the ESP32 for additional Bluetooth functionality. There's an open-source cross-platform app for control. https://github.com/hobzcalvin/blume
