Today I published an Instructable that guides you through the entire process of designing, making, testing and evaluating DIY computer access interfaces using the MaKey MaKey. This is a higher-quality follow-up to some material that I generated last fall for the MaKey MaKey “How-To” Contest, which includes much better photos and drawings, along with lots […]
For the holiday season I worked on two gifts that combine some neat lighting effects with some hand-made glass pieces. The first piece was created in collaboration with glassblower Kenny Galusha on commission for a friend as a Christmas gift, while the second piece uses similar electronics and a hand-made Klein bottle I found online. […]
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.
SurfaceMapperGUI is a Processing sketch for simple projection mapping projects that allows users to easily map image and videos onto real-world objects. The documentation (available also as an Instructable), guides users through the entire projection mapping process, including several examples such as mapping onto curved objects and mannequin heads.
Building upon lessons learned while building the first version of the Eyewriter 2.1 hardware platform (rev A), I set out to redesign the system to require fewer pieces of hardware and less 3D-printed plastic. The result is a much more compact, manipulable and adaptable system that can be attached to monitors, laptops and desks.
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.
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.
I’ve spent a considerable amount of time this semester researching and experimenting with various 3D scanning systems with the eventual goal of scanning student pieces in some sort of curricular activity. I started off by scanning objects (including lots of cool glass work) using 123D Catch. I learned quite a bit about how to successfully […]
Using an Xbox Kinect sensor and ReconstructMe, I scanned a bunch of objects and people to experiment with 3D scanning and 3D printing. I then printed everything out and produced a nice little pile of brightly colored prints, which were given out to the all of the participants.
Circular circuit boards that act as lids for standard mason jars, containing a simple six-LED circuit that mimics the lighting patterns of fireflies. Designed as a DIY kit to someday offer for sale.
