Electronics Projects

This page holds some various electronics projects I’ve done. Over time more of these have transitioned to being just a blog post or on youtube, or being commercial projects (which aren’t posted here). So this list gets a little lean in later years! Currently you have to see details on the old website at https://colinoflynn.com/oldsite, as I haven’t uploaded details here! See the blog tag feature (try the ‘making’ tag for example) to see some of the blog projects. ChipWhisperer - 2013-2015 This is a revolutionary low-cost tool for side channel analysis research. It is now sold through NewAE Technology Inc, but remains a completely open-source tool! OpenADC - June 2012 OpenADC is a high-speed (>105 MSPS, ~200 MHz analog BW) RF front-end for FPGA boards. It has a preamplifier for gain ranges from -11dB to 65dB which can be controlled from the FPGA. Variable VREF on the ADC & optional transformer-coupling for maximum analog BW. Full source, python & MATLAB interfaces round off the project. SDRRF - 2011 Platform for experimenting with Software Defined Radio or communications algorithsm. FPGA+DDR2+ADC+DAC+USB.     Dime Compass - June 2011 Digital Compass, based on HMC5883L. Tiny 1 inch square, with option to pop-out mountable compass smaller than a dime.     GPS Locked Frequency Standard - Dec 2007 10 MHz GPS Locked Frequency Standard. No expensive parts - uses a innovative ovenized crystal design instead of purchasing one.     Snapper - May 2008 Camera flash controller based on low-cost Atmel Butterfly. Allows capture of high-speed events sync’d to various events (sound, switch, water).     IMU - 2006 Small inertial measurement unit, built with an AVR, a 3-axis accelerometer, and 3 single-axis gyros.     Eagle in a Rack - May 2004 Video tracker which runs in real-time to track objects in live video. Uses a single FPGA running at the video pixel rate, no high-speed logic needed.   Drivesafe - October 2003 Proof of concept for a vehicle saftey device to detect erratic driving. Senses movement with accelerometers.     STANN Robot - May 2003 Robotic platform for development of neural networks. Includes backplane which boards can be plugged into, ultrasonic rangfinder, colour detection camera.   Fain Failure Detector - June 2003 Fan failure detector. Uses cheap NTC sensor as flow sensor by heating it up and detecting temperature loss due to airflow over it.     Hovercraft - May 2002 Hovercraft which uses a neural network to control it’s movement. Allows autonomous operation with a single ultrasonic rangefinder.
