The BPI-Pico-S3 is an ESP32S3 development board that has been fully adapted to CircuitPython, and the TinyUF2 + CircuitPython firmware is installed by default. No need to install any drivers in Windows 10, Windows 11, Ubuntu Desktop, or Mac OS operating...
Originally published in 2012. I picked up a set of 10 Sure Electronics 8x8 red/green LED matrices for about $13 on eBay. I figured I could build an Arduino-powered 24x24 LED sign to show messages, run Conway’s Game of Life, and play simple games, and...

Stored wattage can be estimated using the amp-hour rating. I decided that knowing 12 volts X 1 amp for 180 minutes is a rating pertinent to calculating stored energy in watts. Assume a .1 volt drop resulting from testing the battery charged at 12 volts...
We are always wondering where is the best place to manufacture PCB prototypes. Recently PCBWay asked us if we would like to test their PCB service. This post aims to give you a small overview of the experience we had while ordering boards from PCBWay....
My project "RPN calculator" needs to be powered from 3.3V battery. I assume to use a LiON battery. So I tested the LTC1733 battery charger circuit. I have designed small universal PCB. The PCB has size 1.33" x 2.11" (34 x 54mm). If you like...
Long time ago it all started with me trying to find new keyboard. After couple of weeks browsing through every possible manufacturer I got an idea: "How hard it can be to build my own keyboard! It's just few buttons connected to microcontroller, I'll...
For an upcoming Project i wanted to understand how a Radio in a Renault Megane Scenic 3 "talks" to the Display to show informations. (Megane 3 : 2008 - 2016) I started by looking for wiring diagrams to see how everything would connect in a real...
