Tactile Metronome

Tactile Metronome

The Tactile Metronome is a tap-controlled or tap-tempo metronome and "beat looper." "Syncopation machine." "Metronome with an attitude."

A buddy and I created an electronics kit project in the summer of 2009. Click through to get more info and purchase a kit!
RGB LED

Fun with an RGB LED

A cheap RGB LED is controlled with an Arduino to produce a wide output of colors. You can either control the colors with three potentiometers, or let the colors dance on their own.
AVR-GCC Build Process

AVR-GCC Toolchain Build

The main benefit of using Atmel's line of AVR microcontrollers is the well established avr-gcc toolchain, based on the free and open source gcc compiler. There is a nicely packaged distribution for Windows, but nothing nice for Linux users. Given that a compiler toolchain is fairly important, I thought I should try building my own. Here are my notes from installing all the components of the avr-gcc toolchain.
LED Bargraph

LED Bargraph

I wanted to be able to visualize an analog signal using an LED bargraph display. In this project I show how to perform smoothing of an analog input signal and use multiplexed LED outputs.
Voltage Divider

Using a Voltage Divider

A short introduction to an important concept in analog electronics, the voltage divider. Using two resistors, it produces a new voltage based on the ratios of the two resistances.
