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[…]
Tutorial 10 for Arduino: Interrupts + Debouncing
This video was featured on Hackaday.com on 3/8/2011 This tutorial was featured on the official Arduino blog on 3/9/2011 Interrupts are an extremely useful, yet often feared element of microprocessors. Interrupts allow you to run a program, while still being able to react to asynchronous input from the outside world. On[…]
Tutorial 8 for Arduino: SPI Interfaces
This tutorial was featured on the official Arduino blog on 3/9/2011 In this week’s arduino tutorial, we’ll be taking a look at SPI device control using the arduino. Specifically, we’re going to be using the Analog Devices 5204 Digital Potentiometer to control the brightness of several LEDs. Enjoy the video![…]
Tutorial 2 for Arduino: Now with more Blinky Things!
This tutorial was featured on the official Arduino blog on 3/9/2011 That’s right folks, it’s Monday, and the second installment of my arduino tutorial series is here! I spent the last week in Disney World, but now that I’m back, it’s time to get down to business! This week, I’ll[…]
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[…]
Physically Display Website Statistics via an Arduino + Multicolor LED
Behold! My newest little project. This one isn’t as complicated as some of my other creations, but it’s still a pretty cool little device that I put together. I made this as a project for my INFO4320 class at Cornell: “Intro to Rapid Prototyping and Physical Computing”. The assignment was[…]
