Hello and welcome to the Carnegie Mellon University‘s School of Art Fabrication (ArtFab) Facilities. ArtFab is a cross-disciplinary facility dedicated to research and pedagogy and the intersection of digital and physical media and techniques. ArtFab is a part of SIS
Piezo microphone amplifier
Low-noise, high-fidelity preamplifier for piezo pickups, also known as contact microphones. The design combines an OpAmp preamplifier (using TI’s TL072 or OPA2134), together with a JFET buffer that allows the microphone to be “recognized” by things like mobile phones and
MEMS microphone preamp
High quality audio preamp for a MEMS microphone. Design work with OpAmps like TI’s TL072 or OPA2145. This stereo preamp, boards runs on a single A27 battery, has stereo 1/8″ output, has gain potentiometers for each channel. Schematic and board
CNC Router Mold Making and Graphite Etching
#1 Nick Crockett (1st year MFA Candidate) is working in the studio and on the CNC router with Phillip Scarpone (School of Art, Sculpture Instructor/Technician) to create a mold which he will cast a Smooth On Silicon Rubber into for his most
Stereo <> Mono conversion with sox
Thanks to nesno: Converts the samplerate to 48kHz (nothing special): Split the stereo file into two mono files (left and right channel): Create a mono mix-down of a stereo file Converts a wav file to a raw 16-bit signed integer
Shell Script: scan through folders and files by file size
Cutting Aluminum on the CNC
The CNC router has proven to be a very versatile tool with people using it to etch their own PCBs or making plaques. Now, BCSA junior John Choi – johnchoi313.weebly.com – has used it to cut aluminum for his projects. Here’s
TTDT: table top drone tracker
BeckonBot is a software for tracking physical markers to record complex drone choreography in realtime. It uses the ARToolkitPlus library to detect and track fiducial markers and subsequently analyzes the physical marker through OpenCV with data collected from ofxLearn. A
Statuevision – Glasgow
Statuevision – Glasgow is a child project of Statuevision – Washington, which seeks to act as an interface between the audience and local history. The project was exhibited in Glasgow, Scotland on June, 2015. Built in the Unity engine, the audience
Dranimate
Dranimate is an interactive animation system that allows users to rapidly and intuitively rig and control animations based on a still image or a drawing using hand gestures. Dranimate is currently being developed in ArtFab by Zach Rispoli and Ali
