AVR CAN Bus Project – Step 2: Programming Low Fuse

One of the basic functions that the CAN Bus project needs is to be able to communicate with a PC via a serial port.  For modern PC’s the most straightforward way is to connect the AT90CAN128 header board to the host via a Serial->USB converter.  The most common type is the ubiquitous FTDI Cable, which […]

AVR CAN Bus Project – Step 1: Programming AT90CAN128 with Arduino

Last month, I bought a Nissan Leaf EV.  It’s pretty cool driving around in an all-electric car.  Luckily, there’s a great forum called MyNissanLeaf, where Leaf owners can learn a lot, and share information.  I’m currently collaborating with one of the forum members to design and build a Level 2 EVSE.  I will document that […]

Arduino-lite – A Lightweight Runtime for AVR

I just ran across Arduino-lite, a lightweight alternative runtime to Arduino, for programming AVR MCU’s.  This project is spearheaded by Robopeak Project.  It looks pretty cool.  It’s kind of halfway between Arduino, and coding directly with avr-gcc.  It supports the standard Arduinos, as well as: Atmega8(A) Atmega168(PA) Atmega328(PA) Atmega1280 Attiny2313 Attiny26 Atmega48(PA) Atmega88(PA) Not only […]

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 […]

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 […]

How to Use the Arduino IDE with an External Programmer

If you have a hardware AVR programmer, such as the USBtinyISP, you can configure your Arduino IDE to use it for uploading sketches, rather than the standard USB interface.  Why would you want to do this? it uploads faster your project will boot faster you can load bigger sketches, because you don’t need the bootloader […]

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 […]
