Mini xum1541

The mini xum1541 is a USB to Commodore IEC serial adaptor which allows you to connect a Commodore 1541 floppy to a modern PC. The design is based on the¬†ZoomFloppy board and the xum1541 firmware provided by Nate Lawson which he has kindly made available under a GNU General Public License. The mini xum1541 is […]

Stylophone Studio 5

The Stylophone Studio 5 is a project to recreate the original 1968 Dubreq Stylophone which sounds and reacts just like the original (and even contains a replica of the original circuitry) however it also fully supports both MIDI in and MIDI out over USB and can be controlled by studio software such as Cubase. There […]

USB Generic HID Open Source Framework for Atmel AVR and Windows

The Atmel AVR range of USB capable devices provides a wide-range of functionality and peripherals to the professional and hobbyist; however the additional complexity of both microcontroller firmware and host PC drivers is a tall barrier to anyone wishing to get started with USB development. Although the firmware is greatly simplified by freely available open-source […]

AVR ATmega32U4 USB Development Board

Recently I’ve started working with the Atmel AVR range of microcontrollers. The relatively new range of USB capable ATmega chips are an excellent choice for USB device development, however they are only available in surface-mount packages which represents a barrier to a lot of hobbyists since you cannot simply plug the chip into a breadboard […]

Vetinari’s Clock

In the excellent Discworld series the character Lord Vetinari has a clock in his waiting room which is designed to tick irregularly in order to make his visitor feel ill at ease. Inspired by a post featured on¬†Hackaday I decided to build my own version of this clock with a simple and easy to make […]

RC Servo Processor

On a continuing mission to build an autonomous sailing robot we needed a way to more rapidly prototype boat designs and wanted to use a standard remote control model control system to save time by using off-the-shelf parts. When controlling servos with microcontroller based electronics you can use the full 180 degrees of rotation; however […]

RC Servo Switcher

Some fellow members of The Abbenay Hackspace (an open hacker space based in Stockholm, Sweden) are embarked on an ambitious project with the aim of being the first to build an autonomous sailing robot which is capable of circumnavigating the Earth. The project is currently in the early prototyping stages and this RC Servo Switcher […]

RGB LED Love Heart

This project creates a RGB LED lit love heart which is controlled by a PIC12F683 microcontroller. I designed the project as a gift for my wife on our 15th wedding anniversary (since she puts up with my addiction to electronics I thought she deserved something in return!). The love heart is made from a 200x150x6mm […]

MicroSimon

This project shows how to create an MB Electronics Simon game clone using an 8-pin PIC12F683 microcontroller. The game includes a full emulation of the original Simon ‘game 1’ and the ability to select from 4 skill levels which control the number of colours you must repeat in a sequence in order to win the […]

Secure USB Time-Stamp for Data-Logging

This project implements a USB device which provides a real-time clock for the purpose of time-stamping events in an non-networked embedded computer environment. For embedded applications where a periodic time-stamp is required (such as entry-system logs, configuration audit logs, etc.) it is necessary to have a fairly accurate real-time clock (better than that typically provided […]
