Hearing Response Box
This week (January 2013) in the Electronics Shop, John Kostman designed and built a hearing response box for a researcher in the Department of Neurosurgery. Kostman used the Arduino chip that students in an Art and Engineering course use to create programmable circuits. The Arduino chip controls most of what this testing box does. Kostman spent part of day learning about the chip and about 3 hours building this specialized box. He printed the faceplate on the VersaLaser printer. As you can see from the photo, the box has buttons for 8 directions for the subject to press. While undergoing brain surgery, the patient, wearing earphones, will respond to sound transmitted through the earphones. The box's output will be recorded during the procedure for later analysis.
The staff in the Electronics Shop build special orders like this as part of the shop's service offerings.
