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.

This is the Nokia 5110 84X48 display that was used on millions of phones in the late 90′s. In this video, I show how to connect the Nokia 5110 LCD to an Arduino Uno, import the correct libraries to the Arduino IDE, and write code to generate text and graphics on the display.

Working on a project where you need to display something (like data/debugging info)? Why not use an LCD! In this video, I go through various aspects of controlling the device with an Arduino, including setting different types of cursors, toggling the display and even creating custom characters!

If you have a simple Arduino project that uses only a few pins, you might be able to shrink it down to a single 8-pin ATtiny chip. In this video, Matt Richardson shows you how, based on a tutorial from MIT Media Lab’s High-Low Tech Group. The best part is you can use the same Arduino code and development environment that you’re already used to.

Check out the world’s first open-source Bitcoin ATM:
Open Bitcoin ATM is the worlds first open-source automated teller machine for education and experimentation.
Want to make one? Here’s a step by step tutorial. It takes about 7 – 10 hours to build with simple tools. Cost of components are less than $500 new but used parts can be purchased for even less on eBay.

zmashiah @ instructable shows us how he build a display to easily check for his phone status, like battery remaining charge, missed calls and unread SMS. Data is transfered to an Arduino board via bluetooth. He writes:
When at home, I do not carry my phone with me everywhere… so sometimes phone rings or an SMS comes in and I do not hear that. With the volume of music played by the teenagers at home, that is not a surprise so I decided to build a small accessory that will show up the number of missed calls and unread SMS. In order to ensure it is very visible I use a 7 Segment LED display so it can be viewed from distance.
