Portal “Still Alive” on AVR microcontrollers




Yet another Portal-related instructable , but Different !
This one shows you how to :  
1)Build a very cheap device that plays an 8-bit version of Still Alive from Portal
2)On the same hardware , but with a different chip , play the “radio tune”

Here are both projects , in the same video (I hope the video quality does not affect how this entry is rated.I filmed it with a phone camera) :

 Step 1: Parts List

Parts List

As mentioned in the intro , the parts required for this project are really cheap.
What do you need ?
You need to know how to program AVR microcontrollers
Here’s the parts list :
1)A 16 MHz crystal oscillator
2)A 75 Ohm (Or something around that value) resistor
3)An audio jack connector , so you can connect the device to speakers
4)A 7805 5Volt voltage regulator
5)For the 8 bit version of still alive you will need an ATMega16.For the second project , you will need an ATMega644.The parts above are common for both projects.
And the tools list :
1)An AVR programmer
…and that’s it.You really don’t need any tools , IF you have a breadboard and some wires .
But in case you don’t have a breadboard , grab a perfboard , a 40 pin DIP socket for the microcontroller , a soldering gun , and solder everything on the board,according to the schematic (Which is in the next step).

Step 2: Build the beast
