Circuitpython on Seeed XIAO RP2040
nicolaudosbrinquedos Dec 27,2021
Step 1: Unboxing... I2C Not Working?As soon as the card arrived, I installed the firmware version for Raspberry Pi Pico, according to the manufacturer's guidelines. As I had already acquired the expansion card before, I started my tests trying to display text on the Oled display (I wrote another tutorial about it). When I made the call to the I2C bus, I received an error message informing me of the absence of Pullups on the SDA and SCL lines. I tested several resistor values, going from 4K7 to 4...

Raspberry Pi Christmas tree
Kota Dec 09,2021
A Raspberry Pi Christmas tree for programming beginners. It was desinged for my 4 years old doughter and she had fun with it.It can be controlled by any computer language that runs on the Raspberry Pi OS, including Python and C++.This tree requires 40 pin socket, 9 LED/resistors pair to be soldered.I try this thing as simple as possible for biggners, so there is no brightness control(PWM), just ON or OFF.If you wish to change the brightness, adjust resistor value for the LED.Resistor values are ...

Mini T3.2 - Miniaturization of Teensy 3.2 board
FRDM4236 Nov 15,2021
Teensy 3.2 is a great microcontroller board and it's one of the most popular development boards in the Arduino world. Inspired by a user's project on the PJRC forum, https://forum.pjrc.com/threads/33347-Tiniest-Teensy, I have made the Teensy 3.2 board smaller. The Mini T3.2 board is a small Teensy 3.2 compatible board and is based on the same MK20DX256VLH7 microcontroller as the Teensy 3.2 is. It will work with Teensyduino as a regular Teensy 3.2.Note: The Mini T3.2 board includes a built-i...

Apple2-IO-RPi v5
Terence Boldt Nov 11,2021
Update: There is a v6 but the only difference is a jumper to select internal (Apple expansion bus) vs. external (USB) power.https://github.com/tjboldt/Apple2-IO-RPiPurposeThe purpose of this project is to provide I/O for an Apple II series 8 bit computer via a Raspberry Pi Zero W which is powered by the Apple II expansion bus. This includes using the attached RPi Zero W for it's storage, network and processor to provide new functionality for the Apple II.Project StatusSo far, this is a project a...

Raspberry Pi Pico Radio
Verma Nov 11,2021
Pico radio is a simple raspberry pi pico based FM receiver that uses rda5807m to tune to FM channels. One can listen to these FM channels by attaching an FM antenna in the SMA connector and a 3.5 mm headphone in the audio jack.Hardware build:The hardware is very simple and easy to use. It consists of the following components:an OLED display for showing radiofrequency and FM channel info.a tack switch or push-button for changing channels.a LED for indicating signal strength.You need to surface mo...

Ultra Efficient Raspberry pi UPS
DDL Sep 24,2021
The reason this Uninterrupted Power Supply (UPS) was created was because I wasn't satisfied with the things available on the market that would just lower the incoming voltage to charge the battery and immediately boost it to power the pi. This way efficiencies of around ~80% can be achieved. Don't get me wrong this is not terrible but I wanted to do better, which is why this design incorporates a power MUX.For those who don't know a power MUX is just like a regular MUX but instead of signal line...
