ESP32S3 GC9A01 LVGL Smart Watch
Useful Electronics Mar 10,2023
https://youtu.be/Td08fweKXwYIn this tutorial, ESP32S3 MCU is used to display time and temperature data on a round display with a nice looking user interface that is designed using LVGL library with the help of Squareline Studio.SNTP is used in order to get real time data over TCP connection with WiFi. The MCU processes the data and prints it on the GC9A01 display that is interfaced over SPI protocol.Temperature data, on the other hand, is obtained over MQTT connection with Node-Red that is runni...

USB Adapter for Arcade Trackball/Spinner and LS30 Rotary Joysticks
Reboot Mar 08,2023
Using a Raspberry Pi Pico as a USB HID mouse/keyboard device,An encoder based device can be connected, such as a two axis trackball, single axis arcade spinner etc.The encoder device then controls a USB mouse on the computer, including within games.For arcade emulation with games that use mechanical rotary joysticks (Ikari Warriors, Guerrilla War etc),Two joysticks can have their 13 pin connector plugged in and when the joystick is rotating, a USB keystroke is sent out to indicate movement clock...

RP2040 GC Modchip V1
dbzfanatic Mar 01,2023
This is a V1 hardware implementation of the PicoBoot modchip project that uses the RP2040 CPU instead of a full pico. The aim of this project is to make things smaller so they fit better, give DIYers an option to start from, and just assist the community overall.If you like this project feel free to contribute at https://github.com/dbzfanatic/2040Boot or the original PicoBoot project at https://github.com/webhdx/PicoBoot.

Retro Inspired Raspberry Pi Enclosure (portable) — Pi Terminal
Benbouziyane Feb 11,2023
Pi _Terminal is an all-in-one portable enclosure for the Raspberry Pi 4, featuring a 8 inch IPS screen, a low profile ice tower cooler, a UPS using two rechargeable 18650 lithium batteries and a HDMI switcher to use the display on it's own as a monitor.The design was mainly inspired from industrial retro CRTs. The goal wasn't to be the most compact, but rather to have spacious and flexible enclosure to expand and build more within.I used Autodesk Fusion 360 to design all the parts...
