techunboxed.com has a designed a simple build of  Arduino board.

Arduino clones are ubiquitous. A quick web search or a look at any electronics hobbyist website will turn up some kind of Arduino-like microcontroller board. Studies have shown that the absolute last thing the world needs is another Arduino clone that adds nothing or very little to existing designs. One might surmise that these are the exact reasons why someone should never design another Arduino clone, yet here is Ktuluino.

There’s nothing original or particularly compelling about the Ktuluino. The name even has “ino” added to the end which has become so overused that it’s often painful and cringe inducing. With seemingly everything going against it, why would someone make something like this? The answer is… this board was an exercise in PCB design. I need stuff to practice on, and although there’s nothing revolutionary about this board, it is practical. Who can’t use another Arduino, or three?

Yun_board

Let’s explore Arduino Yún’s unique features – Hardware review. [via]

The Yún is unique in the Arduino lineup, as it has a lightweight Linux distribution to complement the traditional microcontroller interface. It also has WiFi and Ethernet connections on board, enabling it to communicate with networks out of the box. The Yún’s Linux and Arduino processors communicate through the Bridge library, allowing Arduino sketches to send commands to the command line interface of Linux.

What happens to electronic components at cryogenic temperatures? That’s the main question Mikail tried to answer with his experiment using liquid nitrogen and Arduino: 65.3Mhz@-196°C. Check the video below to see the magic.

For a little over a year, I’ve been working on an open-source, DIY cellphone as part of my PhD research at the MIT Media Lab. The current version of the phone is based on the Arduino GSM shield and Arduino GSM library. It sports a deliberately low-resolution screen (8 characters, each a 5×7 matrix of LEDs), a laser-cut wooden enclosure, flexure (living hinge) buttons, and a ~1000-line Arduino program that powers the user interface. The phone can make and receive phone calls and text messages, includes a phone book and caller id, and keeps the time. Everything you’d expect from a 20-year old Nokia! (Except snake.) I’ve been using various iterations of the project as my primary cellphone for the past six months or so.

How to capture and reverse engineer an infrared IR code and use an Arduino or other microcontroller to replay the command. Oscilloscope and logic analyser capture, coding, troubleshooting, tounge angle, it’s all here.
In this instance Dave captures the NEC (Japanese) code from his Canon video camera remote control on the digital oscilloscope, figures out all the bits and encoding, and writes an Arduino library to replay the code back, and verifies it with his Saleae Logic logic analyser.

Cap’n ArrDrownHo! is the lovechild of Ardweeny and Boarduino and he’s here to commandeer your AVR ships. ArrDrownHo! inherits pros of both and cons of neither. Pick up an AVR chip and start prototyping instantly on a breadboard! Want to replace that costly Arduino in your project with a cheap AVR, but don’t know how? Use the simple plug-and-play ArrDrownHo! piggybacked onto the AVR to act as interface for programming and provide power.

Niek designed this BareDuino micro, that is available at github:

For some Arduino projects, you don’t actually need that many IO pins. That’s exactly the case when I tried to build a simple RGB throwie that would cycle through colours. I was looking for a cheaper alternative to the Arduino UNO’s ATmega328P when I stumbled across this post by MIT’s High-Low Tech lab. They developed a library for programming the 8-pins ATtiny45/85 from the Arduino IDE. It’s a very smart solution to use permanently in some low pin-usage projects, but you still need to hook up individual wires from your programmer to the ATtiny to be able to program it. That’s when I came up with the idea of the BareDuino Micro.

ObdCanShield

The Arduino OBDCAN Shield connects Arduino board to CAN OBD-II compliant car, light truck, or motorcycle.

  • ISO15765-4 (CAN) protocol
  • Arduino R3 form factor
  • Stacking headers for expansion and connection to LCD
  • Joystick control for menu navigation
  • Provides operating voltage for the Arduino board from OBD connector
  • Serial port operating voltage either 3.3V or 5V, driven by IOREF pin
  • Standard DB-9 subconnector for use with OBD-II cable.

Learn how to load Arduino bootloader on a ATMEGA328 IC using ISP programmer and Arduino board. randofo @ instructables.com writes:

Bootloading an Arduino with a ZIF socket allows you to easily program a lot of chips at once without worrying about mangling the pins. The reason for this is that ZIF stands for “zero insertion force,” and as the name implies, ZIF sockets don’t require any force to take the chip in or out. This means that you do not have to worry about any of the pins bending when you take the chip in and out of the socket. This is particularly useful if you need to bootload a lot of Arduino chips at once for inclusion in an electronics kit or if you need to repeatedly program a chip and transfer it back and forth between a separate circuit board.
