Short builds, teardowns and teaching demos — mostly biosignal hardware you can solder yourself. More on YouTube.
Shorts
Real-time R-peak detection from a wireless ECG front-end, with each beat sounded as it’s detected.
An Arduino-compatible board and PPG sensor, both through-hole and solderable by hand — built for teaching.
Adjusting a PPG front-end’s gain live, while the trace responds — the same adaptive-gain approach used in the smart sock.
Workshops
Some of this material comes out of soldering and biosignal-acquisition workshops run with ScientISST. If you’d like to collab on some of these projects, get in touch.
