Scratch

I found this amazing collection of potential very cheap material
for designing prototypes, including gears and motors.

All we need now is a cheap control interface to Scratch,
switching the 3 Volt motors and the LEDs on and off.

Low cost sensors and sensing for boundaries would be helpful to, any ideas?

As i am new to "Connecting to the Physical World"
and later other people will be new to this threads as well,
a collection of the best ideas including a price tag would be handy
instead of digging through all other posts.

Please post cheap ways to interface these garage sale´s gear
for a few bucks, including a short description, link to both Scratch forums
and where to shop as long it is a few bucks, not everybody wants to shed $ 100.

I would like to shed $ 20, better only $ 5 for control electronics.

My findings so far:
$ 3  hand wired Arduino clone?! see posting...

$ 22 Arduino based with motor, see user Abee´s post below!

$ 45 Picoboard sensor, no motor control, just sensing.

$ 45 Arduino + power driver, but how to Scratch? http://arduino.cc/en/Tutorial/Blink

As long as i have time for i will edit and update this post with your input below
