Badge Tech 🏅
A real-time enamel pin #GLSL fragment shader. Hover to explode it and see every layer that makes the badge. Procedural patterns or your own SVG, rendered with my raymarch engine for crystal dispersion, GGX metal, enamel and holo foil.

DIY Bluetooth receiver.
Bluetooth in → stereo line out.
24V DC in → stepped down to 5V → B0505S-1W isolated 5V out, plus polarized and non-polarized capacitors doing their best to keep the audio side clean and away from the digital noise.
And then, as the cherry on the cake, the actual BT board bastard — soldering that thing requires the hand stability of a neurosurgeon, the patience of a medieval monk, and enough self-control not to turn the whole project into a ballistic object.
Nothing exotic. Voltage, isolation, capacitors, chaos, signal out — and unreasonable self-control.
