A simple “backpack” circuit board for the MaKey MaKey that breaks out each of the female header pins to alligator clip holes so that users don’t need to worry about wires falling out or breaking off during use. This enables more robust use of the MaKey MaKey for use in heavy-use situations like assistive technology and teaching.
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+, […]
In my previous post about openSip+Puff, I showed some working prototype PCBs and demonstrated how it can be used to hit keyboard and mouse buttons for you. The firmware I was using for the boards was very basic and was meant to just verify that everything was working the way it was supposed to. In […]
On September 6th I was lucky enough to present a poster at the Open Hardware Summit at MIT’s Kresge Auditorium and stay the weekend in Boston to check out the area. The conference itself is a gathering of about 500+ open-hardware makers and enthusiasts and consists of both a poster and demo section as well […]
A couple months ago I finalized the design of my open-source “sip and puff” interface, openSip+Puff, and had a small run of boards fabricated through OSH Park. However, I immediately ran into problems with the first run of prototypes, and lost a fair bit of mental steam as a few small problems came up and […]
At the end of June I was lucky enough to be able to present some of my work in open-source assistive technology at this year’s Maker Faire: Kansas City! Earlier this year I heard about the “call for makers” through various blogs I follow and I figured I should give it a shot. They accepted […]
