It is still very much a work in progress, and I have plans to build a new hardware platform in the future… Everything was built from the ground-up: the schematics, PCB, firmware, and PC software. /face-replace/ Tue, 15 Jul 2014 00:00:00 +0000 /face-replace/ This project uses the Kinect face-tracking SDK to replace a user’s face with another, warping it to match the user. It was developed for my computer vision research project at the University of Canterbury. /2014/07/oled-watch-is-alive/ Tue, 01 Jul 2014 00:00:00 +0000 /2014/07/oled-watch-is-alive/ An update to my OLED watch project /fire-hotspot-detection-using-an-rpas/ Wed, 12 Feb 2014 00:00:00 +0000 /fire-hotspot-detection-using-an-rpas/ As part of a Summer Scholarship at the University of Canterbury, I developed a system for detecting fire hotspots using thermal imaging cameras and remotely piloted aircraft systems (RPAS). /2014/01/custom-fonts-for-microcontrollers/ Sun, 05 Jan 2014 00:00:00 +0000 /2014/01/custom-fonts-for-microcontrollers/ Here I show how I created bitmap fonts from true-type fonts, which can then be used in your own microcontroller projects. I’m currently using them in my OLED watch project. /oled-watch-rev-2/ Wed, 02 Oct 2013 00:00:00 +0000 /oled-watch-rev-2/ After making a mistake in my last design, I took the opportunity to re-design the PCB and add some extra features. This will be a work in progress so look in here for related blog posts! /2013/08/pickit2-revisited/ Tue, 13 Aug 2013 00:00:00 +0000 /2013/08/pickit2-revisited/ How to add the latest PIC24 chips to the PicKit2, plus an advanced GUI for editing the device file /2013/07/repaper-e-ink-display/ Fri, 05 Jul 2013 00:00:00 +0000 /2013/07/repaper-e-ink-display/ Experiments with Repaper’s e-Ink display, and driver code for the PIC32 /oled-watch/ Wed, 01 May 2013 00:00:00 +0000 /oled-watch/ As a side project, I decided it’d be neat to have a programmable wrist watch. I had an OLED lying around with the right dimensions, but I needed a breakout board to be able to use it. So instead of simply making a breakout board, I decided I’d turn it into a smart-watch platform! /datasheet-indexer/ Wed, 13 Mar 2013 00:00:00 +0000 /datasheet-indexer/ A simple program for quickly accessing datasheets /3d-printer/ Wed, 20 Feb 2013 00:00:00 +0000 /3d-printer/ An overview of a collaborative 3D-printing project between me and a friend /2013/02/linear-led-pwm/ Sun, 03 Feb 2013 00:00:00 +0000 /2013/02/linear-led-pwm/ In this tutorial, I will show you how to properly control an LEDs brightness using PWM.

Why? During a redesign of the site, I noticed the Disqus commenting system had stopped working, and upon further reading I discovered that Disqus had started injecting ads and selling user data, neither of which I am morally comfortable with having on my site. I have standards, and I will continue to maintain this site ad-free and without trackers or heavy javascript.
