Arduino CAN-BUS OBD Gas Gauge

Posted May 21, 2018 by Chris

"My inspiration for developing this gas gauge was after purchasing a new car (Scion Xa) and wondering what MPG I was getting. After much research on ODBII protocols, and looking into open source software that already existed I delved into my first Arduino project."

Arduino + Bluetooth Keyless Entry System

Posted September 13, 2015 by Chris

"Ditch the key FOB and use your mobile phone as a passive key to access and authorize your car. There are many challenges with such a system but I believe this development is unavoidable. Whilst my prototype is certainly not the most elegant, it does proof a basic point, which is that dedicated physical car keys are a thing of the past."

Motorcycle Gear Position Indicator

Posted January 11, 2015 by Chris

"The objective was to provide a low cost gear position and ambient air temperature display for my 2009 Suzuki V-Strom (DL1000). Also, to (mostly) open source the project design with documentation so that anyone with basic electronic skills can duplicate the design for their motorcycle."

Custom 5th Scale RC Bike Project

Posted November 7, 2014 by Chris

"This was my first attempt at making a rc bike chassis using carbon fibre was for a Thunder Tiger Electric RC motorbike. The original frame panels were scanned and then traced in Adobe Illustrator. I then modified the layout of the panels to reduce weight and then exported them for cutting on our milling machine."

Remote Controlled Kids

Posted October 30, 2014 by Chris

"It all started when I found a ‘Power wheels’ style toy at a thrift shop for $20. As you can see I’m a little excited about it. It wasn’t working when I bought it as there were wiring issues and a bad battery. This wasn’t too much of a concern to me because I planned to overhaul it anyways. It also started out as an Audi; being a BMW guy I figured I would change that too."

Beyond OBDII – Small, Dedicated, Onboard Computers

Posted July 13, 2014 by Chris

"This is beyond OBDII readers, but not exactly iOS and Android apps like Torque. This segment is defined as being a permanent or semi-permanent installation. I reserve the right to keep this definition a “moving target” so as to keep it differentiated from smartphone and tablet apps ;-)."

Automatic Turn Signal Control

Posted March 28, 2014 by Chris

"This is a circuit to automatically blink the turn signal lights of a car a number of times after a short tap of the turn signal handle. This feature is often found in newer cars these days, but not in my 2000 Volkswagen Passat. Instead of buying a new car, I decided to upgraded it with an Atmel ATtiny12."

TARDIS Pinewood Derby Car

Posted March 9, 2014 by Chris

"This January my daughter decided that she wanted to join in her brother’s cub pack’s Pinewood derby with a replica of Doctor Who’s TARDIS on wheels. Her design was pretty straightforward – balsa wood trim, poster paint, paper cutouts for the windows and sign, and her construction was quickly nearing completion…."

Electric Scooter [MK-1]

Posted January 22, 2014 by Chris

"The following page documents the construction of a rather large electric scooter for ‘semi-offroad’ use. My goal was to have something usable to zip over to a train station or grocery store, regardless of it was snowing goblets of ice outside. This project unfolded slowly over the course of ~18 months, in a start-stop fashion, as time became available."

Motorcycle Universal Gear Indicator

Posted January 27, 2012 by Chris

“This is a new design for a universal gear indicator that can be fitted to any motorcycle as an aftermarket accessory. Its main advantage is that its operation depends entirely on the gear shift lever movement, instead of connecting to speedometer and tachometer sensors….It consists of a main circuit including a 7 segment LED indicator, two Hall sensors that are attached to the motorcycle frame, and a small magnet placed on the gear shift lever.”
