Prototype electronics (rev A) for Eyewriter 2.1 built and tested

October 8th, 2013 – For the past few months I have been working on fabricating, assembling, testing and debugging the prototype electronics system for the Eyewriter 2.1 open-source eye-tracking system. Quite a lot of work has gone into this particular update, as I didn’t want to post small bits of progress here on my blog (I use Twitter, G+, […]

Electronics design for Eyewriter 2.1 open-source eye-tracking system

May 31st, 2013 – This past weekend I sent away for the first round of circuit boards (PCBs) to be fabricated for the Eyewriter 2.1 eye-tracking system, marking the first major milestone for the electronics system! The updates on this project have been a little on the light side because I’ve been working almost completely on this! Hopefully this […]

Fully functional 3D-printed M12 lens mount for PS3Eye camera hacking

May 5th, 2013 – While working on the Eyewriter 2.1 open-source eye-tracking system I realized that the most expensive and potentially annoying aspect of the whole system is the optics assembly. To help reduce some of this cost and the number of parts that need to be sourced I experimented with 3D-printing a threaded M12 lens mount.

Overview of the Eyewriter eye tracking system for educators of students with diverse needs

February 22nd, 2013 – What is it? Eyewriter is a low-cost, open-source eye tracking system that can be built using off-the-shelf components and free software. For less than $100, the eye movement of an individual with limited mobility can be captured and used as input on a computer to do things like moving the mouse and drawing. The system […]
