fygen. fygen is a Python library for Feeltech Signal Generators (FY2300, FY6600, FY6800, FY6900 and more)

cnc_pcb_tools. Describes and end-to-end process of milling PCBs with cheap 3018 machines. Provides some helpful utilities written in Python.

epaper_clock. Autosetting clock based on an epaper display. Runs about a year on batteries and has basic weather telemetry (temperature, pressure, humidity).

pico_sharpmem_display. A Raspberry PI Pico library for driving a Sharp Memory Module, such as the LS013B4DN04 or LS027B7DH01. Includes low, mid and high level functions.

rpngo. Implements a programmable RPN library in go

tinygo_picocalc. A minimal "hello world" project that shows how to use the PicoCalc with TinyGo

matrix_clock. "I DON’T EVEN SEE THE CODE ANYMORE" - The Matrix. This is a clock that presents in a matrix-like format on an 8x8 RGB LED matrix. At first you will not be able to read it but eventually the patterns will become clear.

battery_drainer. Hardware to safely discharge LIPO batteries to storage levels

pico_uart_console. Provides an easy-to-integrate console for C-based PI PICO Projects

portable_led_lamp. Contains firmware, schematics and 3D models for a LED lamp that can accept a wide range of voltages.

avr_pico. My AVR libraries I've created over the years. Many of them have been augmented to be usable with Pi Pico as well.

rpncalc. Full featured commandline RPN calculator with macros, unit conversions, and much more.

motorized_macro_rail. Contains a hardware design and firmware for a stepper-motor-powered macro rail module. The module is designed to be attachable to a manual rail. Another goal is to make the module easily removed in for cases where manual mode is preferred (such as field work).

openscad_release_tool. openscad_release_tool bundles your OpenSCAD design along with any library dependencies it uses into a single output directory. his directory can then be zipped up and loaded to Thingverse/cult3d/etc.

light_bulb_changer. Firmware, 3D models, and Schematics for a motorized light bulb changer

game_controller_latency_tester. A hardware design and some software tools for measuring the latency of game controllers with a Raspberry PI
