Datasheets2
Datasheets2 is a simple datasheet/document/PDF organizer that allows you to quickly search your collection and open specific files
Grafana & Outback Solar
A while back I reverse-engineered the Outback MATE protocol and made a Python library for emulating a MATE, and set it up collecting data from the family Holiday House. Then I found an open-source library called Grafana, and was finally able to put the data to use!
pyMATE
pyMATE is a python library that can be used to emulate an Outback MATE unit, and talk to any supported Outback device such as an MX charge controller, an FX inverter, a FlexNET DC monitor, or a hub with multiple devices attached to it.
Driving FPDLink Displays
An intro to the FPD-Link display interface, commonly used in laptop and monitor LCD panels!
RIoTLCD
I’ve always been interested in the idea of re-using old laptop LCDs, but it always seemed out of my reach until recently I had a huge urge to wire up a special sunlight-readable Portege R500 “transflective” LCD, and I discovered it isn’t that hard to do!
Viscons Icon Set
Viscons is a hand-crafted icon set for common filetypes used in development (eg. C header files, binary objects, schematics, 3D models), using a nice eye-soothing sky-blue theme
OSHW OLED Watch
Over the last year or so I have been working on this project; a custom-built smartwatch! 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
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.

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).
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
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!

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!

Migrating Comments to Remark42
You may have noticed that the comment system has been migrated from Disqus to Remark42. 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…
