Guitar Pickup Winder

Posted January 21, 2014 by Chris

"..Since I was going to be using an microcontroller to count the turns and stop the machine when the predetermined number of turns has been reached, I could make this winder do more stuff too. So, I made this pickup winder into more of a pickup winding station…"

Polygraph Prototype (Final Design Project)

Posted January 20, 2014 by Chris

"For our design project we constructed a polygraph which measured pulse rate, GSR, and breathing rate, and performed a discrete cosine transform on the subject’s voice in the hope of measuring a deviation in the fundamental frequency. The measurements were sampled, analyzed, and transmitted to a computer for further analysis using an ATMEL AVR Mega32 microcontroller."

Theremin as a Capacitive Sensing Device

Posted January 18, 2014 by Chris

"Here we show a little Theremin module which plugs onto a Arduino Board that gives out the tune to a speaker or puts out the tune as control signal like MIDI, Servo etc. We were using this device not only as a musical instrument, various kinds of proximity sensors, pointing devices or as interface in combination with Processing, Max or Pd have been build with this technique."

The Open.Theremin

Posted January 16, 2014 by Chris

"Open.Theremin is a open hardware and open software project. You can build your own real theremin."

You Make My Heart Flutter – Wearable Sensing Device

Posted January 15, 2014 by Chris

"For the past few weeks I’ve been working on the first stage of a project that involves hacking Eric Boyd’s excellent Heart Spark PCB pendant and combining it with a sensor module I’ve made from scratch."

Mobile-controlled Home Automation

Posted January 14, 2014 by Chris

&quotA while back I built a mobile-controllable home automation system, and promised to blog it. It’s taken a while, but here it it…DIY Home Automation via WAP and the Web–How-to."

Bicycleledpov: A bicycle Visual LED Artwork

Posted January 13, 2014 by Chris

"Bicycle LED POV hardware V1.0. The microcontroller unit (MCU) is the Atmel AT90USB162, 8 bits microcontroller with USB functionality. MCU will be able to determine the velocity of the bicycle wheel by reading impulses of the hall effect sensor. Knowing the velocity, MCU will read the images from the DataFlash memory using SPI bus, and in the correct timing will send them to the LED drivers using SPI bus, turning on and off the LEDs."

Programming an ATtiny85

Posted January 12, 2014 by Chris

"I recently decided that I wanted to use an ATtiny85 for a small project I have in mind. So I ordered a couple from DigiKey. Once I got them I realized that I only had a very vague Idea on how to go about programming them. I ended up following instruction from the brilliant people of the High-Low Tech group at MIT."

Keyboard I/O Hack

Posted January 8, 2014 by Chris

"A keyboard hack that supports input as well as output. You find many example of keyboard hacks on the web – basically you take out the PCB of the keyboard an replace the keys with something more interesting…"

Another (Arduino) Audio Spectrum Analyzer

Posted January 6, 2014 by Chris

"My last project is an audio spectrum analyzer. The work has been done using a MSGEQ7 integrated. The result is shown using an 2X16 LCD display. The bars are built using defined characters.
The chip only gives 7 info of frequency. I’ve arrived until the 16 bar interpolating values based in the 7 given."
