Noritake 24×6 Character VFD Module

I’ve always thought VFDs were pretty cool. They used to be the rage in high end consumer electronics. Back in the mid 70’s, I built a VFD alarm clock. Recently, I got my hands on a modern VFD module to play with. The Noritake-itron SCK-Y100-24063-N14 is a very flexible 24×6 character VFD module in the same […]

LeafCAN v2 Firmware in Alpha Test

I have been working on v2 of the LeafCAN firmware, which adds a whole slew of new screens, selectable via a rotary encoder.  The rotary encoder is connected to the AD0/1/2 pins on the expansion header of the LeafCAN V2 hardware.  The code is currently in alpha testing, and is available in the development branch […]

UCTronics 3.2″ TFT LCD Arduino Shield with Touchscreen

Updated 2014-03-14 I’ve been looking for a way to add a touchscreen UI to my projects.  To this end, I purchased a UCTronics 3.2″ TFT LCD Arduino Shield.  Most of the cheap TFT touchscreens that I found need about 38 pins, and therefore, need to interface with an Arduino Mega.  What makes this UCTronics shield unique […]

EKitsZone UNO Rev.3 First Look

I recently decided to buy an Arduino UNO R3, to test compatibility with my sketches, which I have been testing w/ a Deumilanove.  The UNO R3 contains an ATmega16U2  instead of an FTDI chip to do the serial to USB conversion, as well as 3 extra pins on the digital side of the board: SCL/SDA/AREF.  […]

Build Ganzfeld-style Photic Goggles (AVS Lightframes)

Building upon my passive Ganzfeld goggles, I decided to build a set of Ganzfeld-style lightframes for photic brain stimulation.  I was inspired by the goggles which come with the very expensive Laxman mind machine: Typical lightframes which come with audio-visual stimulation (AVS) mind machines use point source LEDs, such as this pair which came with my MindPlace […]

Build a Bluetooth Low Energy (BLE) Controlled RGB LED

I have been wanting to play with my RedBearLab BLE Shield for some time, but have been too busy. This weekend, I finally was able to allocate some time to experiment with it. I decided to do something relatively easy as my first project, so as to familiarize myself with the Bluetooth API’s on both […]

LiquidTWI2 v1.1.0 Released

For the Adafruit RGB LCD Shield (MCP23017), I changed the GPIO writing from 16-bit to 8-bits. This increased the library size by 14 bytes, but it’s well worth it, because writing a 47-character string has sped up from 99ms to 76ms on my Arduino Duemilanove – that’s about a 25% increase!  This is vs Adafruit’s […]

LiquidTWI2 – A Lean, High Performance I2C LCD Library for Arduino

I have released LiquidTWI2, a lean, high speed I2C LCD Library for Arduino. This library is an extension of the great work done by FalconFour on his LiquidTWI library.  Notable additions to LiquidTWI: support for Arduino 1.0+ support for Adafruit RGB LED Shield (MCP23017-based) LiquidTWI2 also supports the Adafruit I2c Backpack (MCP23008-based) in I2C mode.  […]

Teensy 3.0 – First Look

I recently backed Paul Stoffregen’s Teensy 3.0 on Kickstarter.  Paul is a contributor to the Arduino project, and is the creator of the Teensy line of AVR-based Arduino compatible boards.  Of all of the projects on Kickstarter that I have backed, the Teensy 3.0 was the by far the fastest to ship after the close […]

AT90CAN Support for Arduino 1.0+

I have adapted the Arduino AT90CANxx support to work with Arduino 1.0+. Also, I have moved the code to github, so that it will be easier to update.  Note that the Arduino 1.0+ support is currently only alpha quality.  I have compiled a few sketches, but I also have found some which currently can’t compile.
