[Noisebridge-discuss] Electronics Question

[Daniel Pitts]

Here is the PDIP version of the chip used as the core of the Arduino: 
$2.26 each (plus $8 shipping). You can get 50 of them for just over $100.

What you *don't* get with that, which Arduino provides, is the USB 
connectivity. You'd have to make your own programmer basically, and you 
can't use the build in Serial class.  I used an Arduino Nano as the base 
to create my own programmer, and it works fairly well.
