STM32 ESC
Wanting to demystify how commodity ESCs work, I built a trapezoidal sensorless BLDC driver. It doesn’‘t have FOC (yet) but it does have LIN.

Transmits button, microphone, accelerometer, and magnetometer data when awake and sips 2.5uA while asleep.
JABICAN-USB Pro
Designed as an open-source alternative to the PCAN-USB Pro, JABICAN-USB Pro runs JABI to provide isolated CAN and LIN access over USB.
ATtiny10 LIN Node
Since LIN transceivers are glorified level translators and LIN is slow enough to bit-bang, I built a LIN node using an ATtiny10.
100BASE-T1 Converter
By connecting the RMII interfaces of two PHYs, this board bidirectionally converts between 100BASE-T1 and 100BASE-TX packets.
Zephyr LIN Driver
Inspired by the CAN API, I designed a LIN API for Zephyr along with one implementation built on top of the UART driver.
JABI (Just Another Bridge Interface)
Easily access any microcontroller’s peripherals from anywhere! Supports all major operating systems and libraries are available for C++, Python, and gRPC.

STM32 DAPLink
After parsing through much documentation, I learned enough to design a DAPLink probe based around the ever-popular STM32F103.
AVRISP MKII
I might be a couple years late to the party, but here’s a tiny board powered by LUFA’s AVRISP MKII project.’
6wire
After learning about the 6 wire measurement technique in industry, I decided to make a board to try it out. It’s also an auto-ranging 4-wire ohmmeter.
MMv3
It still can’t do maze-solving (from lack of trying and resources), but it’s much smaller, easier to assemble, and runs Python.
