This is where I’ll be uploading builds of AVR-GCC for Windows 32 and 64 bit, which will also include Binutils, AVR-LibC, AVRDUDE, Make and GDB. I’ll be trying to keep the builds up to date with the latest tool releases when I can.

Smart Power Bank Keep-Alive
Ever wanted to power a project from a USB power bank, only to have it keep shutting itself off because the current draw was too low? This project aims to fix that with these handy and slightly over-engineered USB modules containing a microcontroller, op-amp, MOSFET and a few other bits to create a pulsed adjustable …

Car Rev Alarm and Gear Indicator

Si4463 Radio Library for AVR and Arduino
This is a library for use with the Si4463 radio IC from Silicon Labs, used (or will soon be) in some of my projects. The Si4463 is configurable in a ton of different ways with options for modulation, packet format, CRC algorithms and has a high output power of up to +20dBm (100mW). The Si4463 …

DIY Digital Wristwatch
Introduction The main incentive behind this project was to see how much I could cram, in terms of both hardware and software, into a wristwatch-like device that is no larger than the display itself. An OLED display was chosen for being only 1.5mm thick and not requiring a backlight (each pixel produces its own light), …

AVR USB RGB LED Controller
While working on an update for my CPU Usage LEDs project I thought why not just make it into a universal RGB LED controller? The CPU Usage LEDs controller took a value between 0 and 255, worked out what colour it should be and then fade to that colour. This was very limiting; changing what …
