WyoLum Innovation Grant 2013 entry – openSip+Puff

December 30th, 2013 – About this page The following is my application for the 2013 WyoLum Innovation Grant, which provides funding for open-source projects to help them become real products. I am seeking the grant to bring my open-source “sip and puff” device, openSip+Puff, to market! If you’d like to support me in this process, you can vote for […]

Updated firmware for openSip+Puff

September 26th, 2013 – 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 […]

openSip+Puff (rev B) prototype boards built and tested

August 27th, 2013 – 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 […]

Snap-together 3D-printable clamshell housing for openSip+Puff

May 5th, 2013 – A 3D-printable, snap-together housing for my openSip+Puff project (an open-source sip-and-puff interface). After iterating through several different designs and parameters I was able to create a strong case that the openSip+Puff circuit board can be easily mounted into, with access holes for the USB cord and vinyl tube.

openSip+Puff board files sent off for fabrication! Schematics, BOMs, new name, Github commits and more!

April 15th, 2013 – After getting a proof-of-concept prototype working two weeks ago, I created a circuit board (PCB) design that integrates the sensor interface from the prototype with all of the necessary circuitry to turn the sensor’s data into useful information and actions like keyboard and mouse presses. Over the weekend I sent this circuit board design off […]

Winning the MaKey MaKey “group how-to” contest – using the MaKey MaKey for custom assistive technology interfaces

November 15th, 2013 – In August I learned about a cool contest put on JoyLabz (the folks who make the MaKey MaKey) that asked for submissions for instructions on how to lead a group “how-to” workshop using the MaKey MaKey. For whatever reason, at first glance the contest felt like a long-shot, until I remembered that I had already […]

Exhibiting open-source assistive technology at Maker Faire: Kansas City 2013

July 28th, 2013 – 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 […]
