Controlled a Beambox Niji Badge over BLE from Windows without the official app. Sending a raw JPEG just produced a black screen — the fix was a custom binary container and a different command type than expected.
Wired M5Stack's CO2L Unit (SCD41) to a CoreS3 over Grove and put CO2/temp/humidity on screen. The factory-fresh sensor read +30% high against a SwitchBot NDIR meter, so I ran FRC over a serial command to pull it in line.
A brand-new CoreS3 failed with 'SD Card initialization failed!' on the stock firmware. Tested two LAZOS cards: the 16GB never mounts at any SPI clock, the 32GB mounts but only writes at 10MHz, and a soft reset wedges the card until power-off.
Un-0 swaps neural-net weighted sums for Kuramoto coupled-oscillator physics, hitting FID 6.74 on ImageNet-64. Still GPU-simulated, and the 1000x energy claim is unproven — no chip yet.
Dug a 2001 Aquaplus P/ECE out of a closet and got my own C game running on it: WinUSB/Zadig for the dead driver, a from-source S1C33 LLVM toolchain, and a 15GB-RAM OOM.
Flicker and ghosting on 74HC595-based seven-segment displays often come from latch boundary placement rather than power issues. A look at how QUAD7SHIFT's 16-bit atomic update avoids the problem.
Local hardware for the 20B Qwen-Image-Edit-2511: VRAM per quantization (BF16 24GB+, NF4 16–20GB, GGUF Q4 CPU-runnable), an RTX 3060 12GB minimum and RTX 4070 Ti 16GB recommended build, plus the 96-angle Multi-Angle LoRA.
