The Corginator v2 uses the Microchip ATSAMD21G18 to implement a small, corgi-shaped development board with the Adafruit Feather form factor, SWD programming, USB Type-C power, charging and programming, as well as single-cell lipoly charging. The Corginator v2 is the successor to the original ATmega328P based Corginator. This design is open source hardware.
Blot is an open source plotter built by Hack Club. Over the Summer of 2023, I did an in person internship in Shelburne, VT to develop a custom control board and a CYPD-3177 based USB-C Power Delivery Sink breakout. The PD Sink Breakout is a small form factor breakout board enabling USB-C Power Delivery from supported power sources at up to 20V @ 5A. It's open source designed in KiCAD v7.
I built a dynamic image gallery that stores images to Cloudinary CDN and maintains a database of CDN links and EXIF data on MongoDB. The gallery pulls images when loaded to be populated with optimized image previews. Important EXIF data is also shown, and each image is linked to the full size image. It powers my photography portfolio.
I wrote a brief explainer explaining how to easily convert older USB-based designs to a more modern Type-C standard. This document has been used to help people with their designs for Hack Club's Onboard grant program as well as my SL2.1A based USB2 Hub.
Upgrading the original ZephyrHub designed in 2021, this new design has four Type-C outputs in contrast to the original USB-A outputs. It serves as an excellent reference design used in the USB-C Conversion Primer.
