Basic stamp without BOE
What would I need inorder to build a project using the basic stamp without using the BOE?
I've been playing with the BOE for a while now and am ready to make my project small (eliminate all of the un-used portions of the BOE).
Can I buy a circuit board and wire the BS2 components by hand?

You can incorporate a BASIC Stamp onto a PCB of your own design using our OEM components. They are available individually and it kit form.
Visit our website and click on Store> Microcontrollers> BASIC Stamp> OEM·to find our BS2 OEM kit (#27291) and individual components.
You can also·put your·BS2 module onto·other·boards, such as the no-frills BASIC Stamp 2 Carrier Board (#27120) , or a custom PCB designed to accept it.
Have fun!

Is there a schematic somewhere that details the necessary connections to power the stamp when connected to a breadboard?

Basically, Vin (6 volts to 12 volts unregulated DC) goes between pin 24 and Pin 23. The BS2 has an on-module linear regulator which will provide a regulated 5 volts for the BS2. Probably you should put a 10 uF capacitor across these lines too.· Pin 24 is +, pin 23 is Vss (Ground).
Your programming adapter then goes on pins 1 through 4. 1 goes to a DB-9 pin 2, 2 goes to a DB-9 pin 3, 3 goes to a DB-9 pin 4 (with a couple of capacitors to keep the PC from holding the chip in reset), and pin 4 (Vss, which is Ground) goes to DB-9 pin 5.
And, DB-9 pin 6 is tied to DB-9 pin 7. That's the "loopback" pin.
As you can see, I use headers for connecting all the external wires. It IS·a pain and takes longer to build initially, but in the long run it is infinitely better than having a rat's nest of wires coming out of the top of the board. It looks so much better, and when you inevitably have to make changes on the board, it's easy to·get to and remove completely without breaking wires and trying to remember where they went.

I'm sure I'll have many questions along the way, but for now I have one: where do I buy the headers (and it also looks like your wires have some sort of connector on them that allows for easy connection to the header) ?
