Teensy 3.0
I just backed the Teensy 3.0 on Kickstarter. It’s designed by Paul Stoffregen, the same wizard behind the Arduino-compatible Teensy boards. It sports a 32-bit ARM Cortex-M4 chip, and is programmable via Arduino and C. This looks like it’s going to be a great platform for building embedded projects that need more power than the [...]
Colorduino Library v1.2.4 Released
Fixed some bugs in v1.2.3 for Arduino Mega & Leonardo. Thanks to wiltwong and Markus Lange for testing! Download here: https://github.com/lincomatic/Colorduino/downloads
Colorduino Library v1.2.3 Released
Thanks to wiltwong and Markus Lange, I have added support for Arduino Mega and Leonardo to the Colorduino Library. Markus also helped to clean up the code a bit for Arduino 1.x. I have added the ColorFill() function to the ColorduinoObject class, as well, so you don’t have to copy it from ColorduinoPlasma.pde. You can [...]
AVR CAN Bus Project: LeafCAN v1.2 Released
Another tweak today, I added instantaneous battery power consumption in KWh to the second line of the display. In order to make room, I had to do away with the V and A characters after the voltage and current draw. Here is the new display: The top line, from left to right, contains Battery Pack [...]
AVR CAN Bus Project: LeafCAN v1.1 Released
I made some minor modifications to LeafCAN firmware today. First, I added display of remaining KWh in the battery pack, based on Phil Sadow’s formula of GIDs * 80 = Wh. Also, the display was a bit blurry when the values were updating rapidly, so I slowed down the refresh rate of the LCD to [...]
How to Program an AT90USB1286/Teensylu/Printrboard with Arduino and USBtinyISP
My first step in loading Marlin RepRap firmware into the Printrboard is to get Arduino to play nicely with it. The method I am going to describe in this article for programming a Printrboard with Arduino will work with the Teensylu or any other device that uses the AT90USB1286 and has an ICSP connector. [...]
RepRap – 3D Printing Project Kickoff – Printrboard First Look
I have been somewhat intrigued by the RepRap project, an open source 3D printer movement, for several years. However, wasn’t motivated enough to jump into the fray until late last year, when I saw Brook Drumm’s Printrbot on Kickstarter. With only about 1 hour left before funding closed, I pledged $500 to get a Printrbot kit. [...]
AVR CAN Bus Project: Step 4 – LeafCAN: Nissan Leaf SOC Meter
I have implemented a SOC (State of Charge) meter for the Nissan Leaf. Many thanks to garygid and others from the MyNissanLeaf forums, for their help in decoding the Leaf CAN bus messages, and figuring out the pinouts. The top line shows the SOC%, raw SOC value, and number of charge bars displayed in the [...]
AVR CAN Bus Project – Step 3: CANspy CAN Bus Monitor
Sorry for the delay in posting the circuit and schematics from my AVR CAN Bus Project – Status Update 1. The circuit for interfacing the Olimex AT90CAN128 Header Board is incredibly simple, and only requires 3 components. Parts List (1) .1uF ceramic capacitor (1) 10K resistor (1) Microchip MCP2551 CAN transceiver Schematic If you’re going [...]
