ATMega32A Dev Board V2.0

Posted November 28, 2015 by Chris

"It was found whilst using the original ATMega32A Development Board that there was a couple of things missing that would make life much easier. So here is is the updated version of the ATMega32A Development Board V2.0."

FPGA Audio Peak Level and Correlation Meter

Posted November 23, 2015 by Chris

"I started this project more to gather some experience with FPGAs, rather than to design or own such a device, but it ultimately developed into a complete design, consisting of several boards."

Digitally Recordable User Modifiable Sound Emitting Tool

Posted November 19, 2015 by Chris

"A modular electronic drum kit that allows recorded samples to be used as drum sounds. We decided to build a modular electronic drum kit because we thought it would be an interesting project to be able to record ourselves and use our own voices or sounds as drum noises."

The Occam’s Microcontroller

Posted November 18, 2015 by Chris

"’Occam’s Microcontroller’ is my article in the Autumn 2013 edition of the G-QRP Club’s ‘SPRAT’ Journal – and the subsequent presentation at The G-QRP Club’s Rishworth QRP Convention, 26th October 2013. This page exists to provide supporting resources for the article (and for subsequent presentations associated with it). These resources include code, schematics and PCB design files."

5×5 LED Display Snake Game (mbed micro)

Posted November 15, 2015 by Chris

"This 5×5 LED Display Snake Game is the first stepping stone to a fully functional 3-D snake game on a 5x5x5 LED Cube which will be built in a future project. This introductory project serves to provide experience for soldering the LEDs and creating a framework for the more involved LED cube."

DIY Cinder Speakers

Posted November 11, 2015 by Chris

"Daniel Ballou and Dashdot are developing a system that transforms the humble cinder block into a high fidelity speaker. Concrete is a low resonance material that minimizes vibrations and reduces coloration of pure sound delivered by the drivers. A drawback of course is that it’s heavy to handle and ship, and labor intensive to mold."

The RIFFLE Open Source Datalogger

Posted November 10, 2015 by Chris

"We are working to develop an open source hardware datalogger that can be placed in the field for extended deployments and measure common water parameters like temperature, conductivity, depth, and turbidity. There have been several iterations of the hardware, including a version based on an ARM chip."

Raspberry PI Serial Port and Breakout Board

Posted November 5, 2015 by Chris

"A simple single-sided board that connects a RS-232 serial port to the Raspberry PI and breaks out some of the PI’s pins for experimentation. The interface board was designed to be simple and used for initial experimentation. It can be built on a single-sided PCB using home-made PCB fabrication methods."

Dualshock Wireless Xbee Controller

Posted November 3, 2015 by Chris

"The controller uses an ATmega328P, the same as used on the ‘Arduino uno’. This makes it very easy to adapt the Arduino platform on the controller. You can upload your sketches via the usb port. The hardware and software is open for everyone, this makes it possible to program your own functionality into the controller."

Digital Tic-Tac-Toe Using ATtiny85

Posted October 30, 2015 by Chris

"This project is an attempt to recreate the classic game in a digital format. To spice things up a bit, instead of using the regular 2 player setup it uses an inbuilt AI mechanism to compete against the player."
