FailureBot 5 – A Line Following Robot

Posted April 23, 2014 by Chris

"The objectives of the FailureBot project originated simply as ‘build a line-following robot’. However, it somehow evolved into a 3-year robotics experiment. My first attempt to build a robot was such a complete failure that I jokingly called it ‘FailureBot’."

3D Pad – Control Without Touching

Posted April 22, 2014 by Chris

"Arduino shield for controlling something without touching the controller. Great for Touchless Gesture User Interface experiments, artistic expression and game controllers. Does not use special parts, just a bunch of CMOS chips connected to an ATmega328 in the form of an Arduino Uno board."

2-side POV For A Bike Wheel

Posted April 20, 2014 by Chris

"In 2005 I spent a few months playing around with a persistence of vision (POV) circuit for a bike wheel. It was my first foray into electronics and micro-controllers so, while it worked, it was a hack."

The Scrabble Keyboard

Posted April 19, 2014 by Chris

"This keyboard was commissioned by a couple of friends of mine from back east (NJ) who are avid Scrabble players. Most of the keys are made from real Scrabble tiles that were all hand-beveled (truly an exercise in patience/masochism!) and built onto a USB, clicky, mechanical-switch keyboard."

Breadboard Based Modular Synthesizer System

Posted April 18, 2014 by Chris

"This system is based on minimizing the differences in the input and output ‘languages’ used in various musical electronic formats. This means finding a way to allow free communication between logic, analog and eventually digital electronics. We are working to achieve this by finding a middle ground between these mediums where signal format and amplitude can be shared freely with minimal need for translators and adaptors."

Microcontrollers: Polling vs. Interrupts

Posted April 17, 2014 by Chris

This week we’ll turn to take a look at a very important concept of Polling vs. Interrupts in our new course: An Introduction To Microcontrollers. Here’s an overview of the lesson:

"In order to interface to the analog world, microcontrollers often have an internal analog-to-digital converter. In this lesson, we will test the converter to understand how it works."

Spartan 6 – FPGA Based Bus Pirate

Posted April 16, 2014 by Chris

"A FPGA based design with a soft CPU and USB device interface implemented in Verilog. A small USB stack implements a virtual serial port over USB, but could be extended to support other class drivers such as Audio or HID. This board is form factor compatible with the Bus Pirate v3.5 case"

Raspberry FM : Project finale

Posted April 14, 2014 by Chris

"This weekend I finally knocked out the final hardware config for me to consider the ‘Raspberry FM’ project complete. What is this project exactly? It’s an experiment I gave myself to combine a Raspberry Pi, Makey Makey, MicroRAX, and MPlayer to create an auto-on internet radio player. I called it ‘Raspberry FM’ after a combination of the Raspberry Pi, and Soma FM, my favorite internet radio station."

A Simple Ultrasonic Posture Sensor

Posted April 12, 2014 by Chris

"Often we don’t care about our posture which can result in back pain and worse. If someone tells you to sit upright this is easy to do, but it won’t hold on for more than a few minutes. Now wouldn’t it be great to have a device that can remind you to improve your posture?"

Microcontrollers: Analog to Digital Conversions

Posted April 10, 2014 by Chris

Now for some real fun, we’ll take a look at how to convert from Analog to Digital in our new course: An Introduction To Microcontrollers. Here’s an overview of the lesson:

"In order to interface to the analog world, microcontrollers often have an internal analog-to-digital converter. In this lesson, we will test the converter to understand how it works."
