This is a Meshtastic Solar Node PCB based on the Heltec HT-CT62 and the linear solar charge controller TI BQ25185.
Digital (RS485 - based) soil moisture and temperature sensor
RP2040-based USB DMX dongle with integrated web server
Pro Micro/Elite-Pi compatible RP2040 board with USB-C, 8MB flash and up to 25 GPIOs
Circular LED Panel
Semiconductor cosmic radiation detector Silicon diode interface.
MPTT solar charge controller for 18650 cells.
Without using a USB-C PD controller chip, handling communication over the USB cable, USB-C standard allows to get 5V up to 3A through a hardware availability detection. Here I show a design developed on KiCad and made through JLCPCB, powering from a USB-PD source and providing 5V and 3.3 (through a step-down converter) up to 3A.
A 2-layer PCB for a small sumobot including MSP430G2553, regulators, motor drivers, and IR receiver.
GNSS-powered, seven-segment table clock
Klein keyboard is a 36 keys, columnar staggered, split ergo keyboard
A controller for miniature stepper motors
Microphone Pre-amplifier
A dual channel brushless motor controller based on the RP2040 microcontroller, designed in Kicad.
All the sources (Schematics, PCB, VHDL, BIOS sources) for the M8SBC-486. This project is a 486 Homebrew computer, with some efforts to make it kinda PC compatible
Open Source, easy to use Ethernet connected stepper motor controller. Built in FreeCAD, KiCAD and Arduino.
a wireless-only split keyboard based on the chocofi
