KYLE LED Nameplate
A tiny 45 x 16 mm LED nameplate badge that spells KYLE — four red LEDs (one per letter), each with its own 330 ohm current-limiting resistor, fed from a 2-pin VCC/GND header. Defined entirely in code with tscircuit.

Wrist Health Tracker
A wrist-worn nRF52840 health tracker for sleep-quality scoring: heart rate, HRV, SpO2, steps and skin temperature, logged to flash and synced over BLE to a home server. Four-layer 32 x 30 mm KiCad board with single-sided assembly, a 3D-printed 35.7 x 33.9 x 9.95 mm case and a magnetic pogo-pin dock.
Solar MPPT Power System
A 30 W solar battery charger with regulated 5 V and 3.3 V rails: an STM32G031 running perturb & observe MPPT and a CC/CV charge state machine, steering a TI LM5175 4-switch buck-boost through a single analog control input. Four-layer KiCad board, schematic and PCB generated from Python, with an electrothermal simulation run against the published board file.
