Things I've built across AI, circuit design, quantum computing, or general topics of interest
An open-source platform for documenting, versioning, and collaboratively maintaining dilution-refrigerator wiring diagrams. Built for quantum-hardware research labs with workspace-based access control and self-hosting support.
A compact, transformer-free driver for programmable touchscreen haptics. The two-layer PCB combines a 12-to-135 V boost stage with PWM waveform synthesis, creating software-defined electrovibration signals from 60 to 600 Hz.
An empirical test of my own "buy the crash" investing rule against ~268,000 U.S. stock crashes since 1925. The bounce is real (but weak), and bigger crashes have worse odds, not better.
