Tutorial 1 for CadSoft Eagle: Schematic Design

This is the first in a series of tutorials that will focus on using the very popular Eagle CAD program to design circuit boards from concept, to schematic, to board layout, to printed circuit board. In this first episode, I’ll show you how to get Eagle up and running, and how to design your first schematic.

Light-Up Mortar Board. Because I can.

This was one of those “Why Not?” moments.  While sitting at dinner with family and friends the night before my graduation commencement, somebody mentioned that a light up Mortar Board would be really cool.  Realizing that I had all the parts necessary to make one in my apartment, I went[…]

Tutorial 14 for Arduino: Holiday Lights and Sounds

This is one that I’ve been excited about for a long time.  When element14 asked me to put together a holiday special, I knew just what to do.  This episode is the most technically complex so far; it covers non-inverting op-amp circuits, low-pass envelope detection filters, buffers, power management, and[…]

Using the SudoGlove as a Performance Piece

I’ve already shown how the SudoGlove Control System can be used to synthesize simple music.  However, I used my enrollment in a digital music class this past semester as an opportunity to further expand the capabilities of the SudoGlove as a performance medium.  In the video below, you can see[…]

3D-Printed Glowing Puzzle

Ahh yes, the joys of college – awesome people, parties, concerts, quadrangles (they are important!), problem sets, final exams, and of course, awesome prototyping equipment.  Take for example the objet 3D-Printer.  We use one in Cornell’s Computational Synthesis Lab (CCSL), where I am employed as an undergraduate researcher.  But the[…]

Arduino-Powered Jack-in-the-Box Toy

Remember the last design project I posted?  Well this second one is for the same Physical Computing class, but is totally different.  This time, the assignment was to create a Jack-in-the-Box toy.   To make mine unique I added password protection and an alarm system to the box.  Check out the[…]
