This week, we paid a visit to the surprisingly out-in-the-open Champaign-Urbana Community Fab Lab; a free community center-like makerspace open for anyone. The Fab Lab is aptly named as the inner workings of the building are almost like a laboratory filled with fabulous creations by the volunteers and others who happen to stop by. Unlike our Digital Making Lab, it contains not only 3D printers, but other varieties of technology designed for the specific purpose of creation. These include sewing machines, paper cutters, laser engravers, and soldering stations. The lab contains a plethora of methods for people to express their creativity; it’s a shame that it is not very well known.  < Outside view of the Fab Lab

For the first week here in our 3 part saga in this lab, one person from each of our groups was assigned to a station in the lab where we would participate in a different workshop to make something out of nothing. For my personal station, we worked in electronics. I chose this because as an electrical engineering major it was definitely in my all you expertise and I knew that I would be able to learn something to improve upon. Our project was creating a type of light-sensing electronic circuit using LEDs, a photocell resistor, and an Arduino. Depending on the amount of light sensed by the resistor, a different color LED would light up. If no light was sensed, then all the LEDs would turn on. The project involved looking at some schematics and quite a bit of soldering, and the end result as it currently stands (an Arduino board with a bunch of wires and LEDs branching everywhere) did not look so appealing, but the functionality was the true beauty of it. Plus, we should be able to improve upon and make the design “prettier” in our next workshop. The other two groups were split into those working with laser cutters and coding in the computer lab portion of the Fab Lab. Laser cutting is another type of 3D printing in a sense, but in a way opposite to the norm. Instead of starting with nothing, your starting material is already there. You just need to decide upon a design and what portions you wish to cut out rather than add on. The results are stunningly precise. And while coding might not seem as glamorous as the other two activities, it is the basis of modern day electronics. Virtually every device for use by citizens requires some programming: phones, computers, televisions, and the 3D printers we use in our lab. It may not inherently make some visually stunning object, but without it we wouldn’t be able to use the machines that make those objects in the first place. All in all, these activities were extremely enjoyable to spectate and participate in, and in doing so we’ve gained knowledge of more methods for our use in not just our final project, but Making as a whole.
