Perfect project for geeks who are looking for a cool desktop gadget. It's a simple desktop facebook notifier.

The project is made using 8051 micro controller, but can be easily ported to other micro controllers or arduino.

The desktop app is written in python.

Things you'll need

8051 microcontroller board and microcontroller
PL2303 USB serial interface
Jumper Wires
LED
BC558 PNP transistors
Soldering iron
Old Books
Printer
Glass/Acrylic
USB cable
Scissors, Scale, Tape, Glue etc
Loads of patience

Project did not come out as awesome as expected. Couple of suggestions before you go for this project.

Use a plastic case
Try Decal instead of a paper printout
Use acrylic instead of glass

Step 1: Build the Outside Box

I have used cardboard from an old book. You can use a plastic casing if you have any or can try with other materials

Step 2: Electronics

Electronics used

8051 microcontroller board
PL2303 USB serial interface
LED's
BC558 transistor
Jumper wires

I have connected 5 LED's to transistors and connected them directly to the 8051 microcontroller

I have used PL2303 for USB interfacing. One of the most awesome devices i have ever purchased. It's really cheap and drivers for this device is present in most computers by default. It has a 5v and 3.3v output, which is perfect for connecting 5v to my microcontroller and 3.3v to my led's.

The interface is very very simple.

Step 3: Final

Place the electronics in the enclosure box made from cardboad. Print the facebook image onto a paper and stick it to the glass. Place the glass on top of the enclosure.

Enjoy your project
