Office Lights Installed

Last year I was finishing part of my basement to build a new office for myself. A friend recommended I utilize some of the wasted space behind one of the walls by adding some built-in shelves. I grew up working in my father’s cabinet shop, I couldn’t just build simple flat shelves. Instead I came up…

Spectrum Analyzer

I’ve started work on a spectrum analyzer built around the MSGEQ7. A spectrum analyzer measures the magnitude of an input signal versus frequency. – Wikipedia In this case the MSGEQ7 will be measuring an audio signal, cutting it up into 7 frequency bands (lows/mids/highs/etc.). The data will be read by an arduino and displayed on a series…

Hacking a Swing

The newest member of my family has become quite attached to swinging. The problem was that the swing was battery powered. I was reasonably surprised at how long the batteries lasted–nearly a month of every day use. Still, when they finally expired, I was reluctant to make another purchase. So instead, I embarked on a project…

Office Lights

How many projects is it okay to start without finishing at least one? It seems I’m determined to find out. I’m currently in the process of finishing a room in my basement which will become my new office/hackerspace. Naturally, I incorporated copious amounts of LEDs into the design. I picked up a couple of reels…

TLC5940 library for chipKIT

As part of our keyboard project, a friend and I set out to develop a library for the chipKIT to communicate with the TLC5940 LED Driver. The chipKIT, if you’re not familiar, is a 32-bit arduino clone that runs on the PIC32MX family of processors. While Digilent, the company behind the chipKIT, has done a great…

Catching Up

A lot has happened on the Keyboard project since I last posted. Let’s get you up to speed. After etching the TLC boards in the last post, we drilled holes for the components and began mounting them. It quickly became apparent that the boards were of less quality than they seemed. The traces were very…

Etching a Circuit Board

As we started formulating our keyboard project, it quickly became apparent that we’d need a handful of circuit boards. Initially, it was my intention to order them from a site like batchpcb.com. Typically, circuit boards are printed in mass quantities, but when you need just one or two copies of a particular board, sites like…

Propeller & TLC5940

When we began work on this project, we were planning on using an arduino at the heart. However, after some initial tests, we found that the arduino just wasn’t powerful enough to keep up with all of the processing that we wanted to do. A friend pointed us towards the propeller platform. While I wasn’t…
