STM32 Microcontroller PCBAug 2026
A microcontroller board built around an STM32F411, with an onboard IMU for motion sensing, USB for power and data, and a header for flashing and debugging. Built with an MPU-6050 IMU, AMS1117 LDO regulator, and laid out as a four-layer PCB in Altium.

LED Sequencer PCBJun 2026
A circuit that lights up 10 LEDs one after another in a chase pattern, with a knob to speed it up or slow it down. Built with a 555 timer and CD4017 counter, simulated in LTspice, and laid out as a two-layer PCB in Altium.

RobodogJan 2026
A little robot that follows you around, keeping a steady distance using ultrasonic sensing and PID-controlled motors. Built with an Arduino Uno, C/C++, and wheel assemblies designed in Onshape.
