Beaglebone Cookbook

Mark A. Yoder is a professor of Electrical and Computer Engineering (ECE) at Rose-Hulman Institute of Technology. In January 2102, he was named the first Lawrence J. Giacoletto Chair in ECE. He received the school's Board of Trustees Outstanding Scholar Award in 2003. Dr. Yoder likes teaching Embedded Linux and Digital Signal Processing (DSP). He is coauthor of two award-winning texts, Signal Processing First and DSP First: A Multimedia Approach, both with Jim McClellan and Ron Schafer.

Jason Kridner is the cofounder of the BeagleBoard.org Foundation, a US-based 501(c) nonprofit corporation that provides education and promotes the design and use of open source software and hardware in embedded computing. As a more than 20-year veteran of Texas Instruments and the semiconductor industry, Kridner has deep insights into future of electronics, pioneering both TI's and the semiconductor industry's open source efforts and engagements with open hardware. In his free time, Kridner uses BeagleBone Black to explore his creativity with creations like the StacheCam, which uses a webcam and computer vision to detect faces and superimpose fancy mustaches.
