Step 1Go Order Parts!
Necessary Parts List (stuff to buy or scrounge):
= Around $10, even if you go deluxe. Half that if you can find an old parallel port cable.
Add-ons
A pushbutton switch or two: $1.
A piezo speaker: $1-$5
Light sensitive photocells: $2-$6
Breadboard for making complex circuits: $8-$10(?)
Other Stuff You Oughta Have
Computer: The older the better because it needs a parallel port.
Hookup wire, solder, soldering iron
Super-duper glue
Source of ~5v DC: Batteries will work, and old computer power supplies are perfect.
I get a lot of stuff from Sparkfun because they're
fast, reliable, and fairly priced. They carry AVR chips (but seem to be out
of ATtiny13's at the moment). They've got everything on the "Necessary"
list in one place, nice website.
If you're gonna be ordering a lot of chips, you can get a deal from Digi-key or similar. For instance: ATtiny 2313 for $2.36 each. They've only got 27,853 more in stock, so order quick. (Make sure you get the DIP form-factor.)
Go order stuff now, and we can set up the software side while you wait.
The waiting is the hardest part.
Atmel ATtiny2313 chip: $2.50 - $3Socket for chip: $1Parallel port connector (DB25): $3 at Radio Shack or $0.95 at SparkfunHeader Pins: $1-$2 (at least one strip each male & female, maybe 2 female)Some LEDs and resistors: $1

Just a reminder, as i was looking everywhere for 2v batteries :)

You can clearly see the pin numbers on the connector.
Will be trying this out and ill report back with some pictures =)
so i'm searching for the chip that you mentioned in digikey. problem though is, there has been more than 1 result. so i was wondering whether you could like give the detailed spec of the atmel chip or maybe verify whether the chip given by the url below is the right one. thanks in advance. http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=ATTINY2313-20PU-ND
If in doubt, have a look at the docs to see which pins they are.
AVR Freaks Device List is a good resource.
