Earlier this year I was hunting around for some sort of fun plant-related summer project to play with, and came across the idea of aquaponics – a closed-loop system that allows you to raise both fish and veggies. I spent a few months geeking out and reading about different ways of doing it, and I [...]

Progress since the last built update was a little slow, because I had to wait to get some money (hooray student loans!). Well, late last week that problem was solved so I went ahead and ordered all the electronics for the printer! This is by far the most expensive part of the project. In fact, [...]

While working on the Eyewriter 2.1 open-source eye-tracking system, I knew I wanted to find ways to save cost as much as possible to make the end project / kit more affordable and accessible to people. The most expensive and potentially annoying aspect of the whole system is the optics assembly, so I’ve been looking [...]

Last week I spent a couple of days iterating through prototypes of a design for a snap-together housing for my openSip+Puff project (an open-source sip-and-puff interface). A couple of weeks ago I sent my circuit board designs off to be fabricated, which I’ve since received and soldered a few components to. Now I’m ready to [...]

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 [...]

A couple weeks ago I used an XBox Kinect sensor and ReconstructMe to scan a bunch of objects and people to experimenting with 3D scanning and 3D printing. The following week I printed everything out and produced a nice little pile of brightly colored prints. Prints of scans from Tuesday (3.26.2013) The first round of [...]

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 [...]

Over a year ago, I created a small batch of mason jars outfitted with LEDs that blink to mimic the behavior of fireflies. Since then, I’ve gained a bit more experience with CAD and PCB production so I thought it would be a great project to turn into a kit. In addition to transferring the [...]

Over spring break I got my hands on an XBox Kinect so I could start experimenting with it as a 3D scanning interface. I’ve been working with ReconstructMe Console, which I’ve heard a lot of good things about, and I’ve been getting some pretty decent results. I was hoping to be able to use a [...]

I’ve been making some good progress on my self-sourced Prusa Mendel i2 3D printer; so far I’ve gotten all of the required hardware (vitamins), cut up and rounded the rods and got the basic frame assembled! Sourcing and buying the vitamins The official RepRap wiki has a pretty straightforward and simple BOM, which I put [...]
