Wi-Fi HaLow Hat for Raspberry Pi Pico
Jonathan Garnier Dec 06,2024
I wanted to make a small Wi-Fi HaLow device that worked on easily accessible hardware such as the RPI Pico 2. This board uses Wi-Fi HaLow modules with the Morse Micro MM6108 chipset for long range wireless connectivity, as well as a temperature and humidity sensor (SHT40), battery charging circuit, three LEDs, and a QWIIC connector for any other I2C based sensors.

Pi Pico Based Data Acquisition System
Seczkowski Dec 03,2024
Pi Pico Based Data Acquisition SystemI'm excited to share a project I've been working on, a compact 8-channel strain gauge data acquisition system designed for use in experimental rockets. This system is meant to measure the loads and forces acting on the rocket during flight, and it's all built around the Raspberry Pi Pico platform.The Backstory: CLES-FACIL Rocket Club at INSA LyonI developed this system for CLES-FACIL, the rocket club at INSA Lyon, where I am an active member. Our club's prima...

WALKPi PCB Version
Arnov sharma Nov 27,2024
Greetings everyone and welcome back, This is the WalkPi, a homebrew audio player that plays music from an SD card. It is made out of a Raspberry Pi Pico 2 and a DF Mini Player.Remember the Walkman? The phrase "walkpi" is a pun.The WalkPi gets its name from the fact that it is just a walkman that is powered by a Raspberry Pi and is a little less sophisticated.This project is a follow-up to the walkpi project I created earlier using a breadboard.We added an SSD1306 OLED display and a few buttons t...

PiColeco - Raspberry Pi Pico (Clone) Multicart
Dan Hoover Nov 23,2024
Full project details at https://github.com/aotta/PiCOLECO/tree/main?tab=readme-ov-file Thank you to Robin Robin Edwards and his A8PicoCart for the idea and to A. Ottaviani for this implementationNEW version 1.0a uploaded with partial support for Megacart switch banking roms up to 128kbPiCOLECO is a multicart DIY yourself based on cheap "purple" Raspberry Pi Pico clone. It should works for all roms up to 32k, but there's no enough RAM on Pico to handle 128k or larger multirom.WARNING! "...

PiWiBot One
Jason Oct 25,2024
Tethered Mini Sumo robots are a great "Tech Ed" project for high school age students. But what if you could remove the tether? And keep the project under $20CAD?That was the challenge that a high school teacher in Vancouver, BC, laid out for me... and the PiWiBot One is the answer. It uses through-hole components so that novices can learn to solder the board, and has a base configuration that is very inexpensive... but with plenty of options to grow. Once students master the basics of moving the...
