Lampduino – an 8×8 RGB Matrix Floor Lamp

This past weekend, I finally finished building my 8×8 RGB matrix floor lamp.  I call it Lampduino.  A Processing sketch running on a host computer controls Lampduino via a USB connection.  When turned on without a computer, it automatically displays a soothing plasma simulation. If you want to build one of your own, I wrote a […]

8×8 RGB LED Matrix Construction: Step 2 – Wiring

The first step in wiring up the matrix is deciding on the method.  I immediately ruled out soldering, because it’s messy, slow, and smelly.  Also, it incurs the risk of overheating the LED’s as well as being hard to repair.  I also ruled out using crimp-on connectors due to expense.  After pondering it for a […]

8×8 RGB LED Matrix Construction: Step 1 – Cutting Foam Board

I started building my 8×8 RGB LED matrix this weekend. The first step was mechanical construction of the matrix. Below are the materials I used: I recycled a piece of foam core poster board. This kind of poster board is composed of two sheets of thick paper, with a piece of foam sandwiched in between. […]

Colorduino Library for Arduino

I wrote a Colorduino library for Arduino.  It handles initialization and double-buffered drawing on ITead Studio’s Colorduino.  It is also compatible with Itead’s Arduino RGB Matrix driver shield. Included with the library is a sample sketch to show how to use it, ColorduinoPlasma, which draws a pretty plasma on an 8×8 RGB matrix. To install […]

ITead Studio Colorduino – A Preview

ITead Studio kindly sent me a Colorduino for beta testing. The Colorduino was inspired by SeeedStudio’s Rainbowduino LED Driver Platform. Its form factor is very similar to that of the Rainbowduino, and the layout of the connectors was intentionally designed to mimic the latter. Both boards are based on the ATmega368 MCU, and are Arduino […]

RGB LED Testing

I bought 100 diffused 5mm RGB LED’s on eBay for my upcoming project, an 8×8 RGB matrix. I was extremely impressed by the fast (free) shipping – 7 days, all the way from China! Much to my chagrin, when I started testing them, I found that the vendor had sent me common cathode, rather than […]

Build Your Own Daft Punk Table (5×5 LED Display)

Welcome my blog. This is my first post. This is a 5×5 LED matrix display I built, using an ATmega368 microcontroller (arduino) and 25 warm white LED’s.  It was inspired by the Daft Punk coffee table, which is no longer sold. I posted my first Instructable last Sunday.  It got selected by the editors to […]
