Small USB development board for Android. Smartphone powered, USB 2.0 communication, direct connection, open sourced API.
It’s an ARM Cortex-M3 development board that connects directly to your Android smart phone micro USB port. It’s powered from the phone so it has enough power for all sorts of applications without extra batteries, and when the device is connected to the phone the appropriate application starts up automatically.

hackshed.co.uk has a tutorial on how to interface a Nokia 5110 LCD to Arduino:
We purchased one of these very cheap, very cool 84×84 LCD backlit screens off of eBay a couple of weeks ago.
It’s a very nice product for adding visual elements to your projects at a very low price. We paid £3.89 for the screen and it was delivered a few days later.
Take a look below for connection instructions and example code from Adafruit on how to get this up and running with your Arduino.

luca @ lucadentella.it build a nice app that let you configure an RTC chip using a PC GUI and your Arduino board. The system is composed by two elements, the PC GUI written in C# and a sketch running on Arduino. The RTC is connected on the Arduino using I2C interface and Arduino is connected to PC using a simple serial protocol.
I chose to use the Adafruit’s RTClib library to talk with the DS1307 chip, that is for sure one of the most used RTC in the hobbistic world. The connection between the IC and Arduino is established using the I2C bus.

An incredibly small board at your fingertip: raising funds on Indiegogo!
A 100% Arduino IDE compatible, 32KB USB development board small enough to fit on your fingertips and cheap enough to leave in any project.
Having used several development boards over the years we soon realized that most of them are designed to be used for a single purpose. Having hacked some to increase functionality, we reasoned that not all boards would easily allow this and soon realized the need for boards which are feature rich, cost effective, yet easy to use and deploy in numerous applications. We set out to design such boards and this is where it has led us, our first pit-stop: The µ-nex.
The u-nex is a very compact Arduino compatible board designed around the Atmega328p micro-controller. It features 32KB of flash memory with ALL the micro-controller pins being brought out to enable you to build just about anything you would want to build with an 8-bit micro-controller from autonomous flying vehicles to LED cubes. Designed from the ground up to give you maximum possible versatility.

A tutorial on interfacing LCDs (liquid crystal displays) with Arduino. We take a look at libraries and the role they play…and the potential issues, errors and troubleshooting involved.
We look at several types of displays but concentrate on the 4×20 Sparkfun serial enabled LCD display.

Audigi @ instructables.com show us how to use an Arduino board to burn Arduino bootloader to mcus on a breadboard. He writes:
Connect Arduino Uno board to your computer. Start Arduino program and from examples choose “ArduinoISP” sketch and upload it to “Arduino Uno” board. Please make sure you select the correct board name and serial port. Now this board is ready to program new Atmega-328 chips on the breadboard as shown in the next step.

Julian Ilett show us how to program the Pro Mini Arduino using a simple USB to Serial adapter. Three USB to Serial adapter are tested here. He writes:
Here I attempt to use 3 different USB to Serial modules to program a clone Arduino Pro Mini. The chips are the FTDI FT232RL, the Silicon Labs CP2102 and the Prolific Technologies PL2032HX.

This is a great credit card sized business card and gaming console based on Arduino.
The primary trick of this design is having milled cutouts made for surface mount components to be press fit into, using the circuit board as a kind of frame. Components selected have a thickness near that of the circuit board (1.6mm). Furthermore, to minimize the board thickness, the Atmega328P is inverted so that the bulk of its height below the surface. The result of equal thickness and recessed installation provides a flush appearance. The primary benefit beyond the aesthetic quality is the device is easily slid from a wallet. The high quality boards and the excellent service from oshpark also makes this build possible.
