Gerber Viewers

When creating a PCB to get made by a 3rd party you need to generate some files to send. There is a industry “standard” called the Gerber format or more commonly Gerber files. Most PCB software can generate these and
KiCAD-GPT is here

I’ve been experimenting with a Beta version of KiCAD that adds an AI based interface to the a popular electronics design application. It has been trained on example circuits found in datasheets, old magazines and discussion forums. Rather than needing
ATX Power Control Board

When I built the MING Pi, I needed a way to signal to the ATX power supply that it needed to turn on. I did that by cutting an ATX connector in half and soldering the Power On wire to
Simple Fan Speed Controller

A simple fan controller based on an ATTiny board and DS18B20 temperature sensor generating a PWM signal driving a power transisitor to control the fan.
Pi vs Arduino

Last week I gave a talk showing three different ways to flash an LED. One of the questions at the end was why would we use a Pi vs an Arduino?
Jumbo RGB LED

At the end of last year, I was working on a project for Element14 Presents that combined woodworking, power electronics and high powered LEDs. I upscaled an RGB LED 100 times from 5mm to 500mm. There were a few parts
Arduino Portenta

For a recent project, I’ve been using a new Arduino Portenta Pro board. It has proved to be a powerful board but also challenging to use.
Gates Update

Over the last week, the gates have been painted and the holes for the bases have been dug and filled with postcrete. To ensure the holes were all filled to the same level I remove the gravel between the holes
