  They're usually called perfboards -- get the kind with plated-through holes if you can; they're usally better quality.

  Radio Shack has dozens of "Solder-Ring" boards that are perfect for prototyping when you want to Solder components in place.· I recommend "Sockets" for any ICs.

  Okay, I just took a look at the boards Parallax offers and came across the Basic-II Carrier Board. Now, it seems like the holes on this board are independent of each other hole, unlike a breadboard which has each row of holes connected to each other.· Now, how would I connect a pin from an IC to one of I/O pins on the stamp? I guess you would have to solder the wire AND the pin to one hole, but that seems pretty difficult.· Like here's a perfboard I came across with two holes per pad:

  This makes more sense to me because you could solder the pin to one hole, and then solder the wire to the hole beside it.

  The Carrier Board was designed to provide a convenient board in which to program the BASIC Stamp and to add permanent hardware (via soldering). It's no more difficult to use than any other perfboard -- and is nice because the programming connection to the BASIC Stamp is already setup.

  2 comments:
  1) There are different perfboards, some have just copper rings around the holes in the board, some have rows of those rings connected together in groups of 3-4, just like on your breadboard.
  
  2) Try to stay away from RadioShack. That place is EXTREMELY overpriced, especially for cheap small components. If this is not a project that has to be done by tomorrow morning try to order things online. I had my share of frustration with RS, building a project for school, being limited on time and having to run down to RS to buy components at ridiculous prices.
  
  Ok, im done rambling on now.

  So say you use the Parallax Carrier Board, and you're trying to connect a pin from an ADC to one of the I/O pins on the stamp, you would have to solder the ADC pin and a connecting wire to the same hole? Would the wire go above the hole or below?

  That's a matter of style; I tend to put components on the top side of the board, wires on the back.

  And you just use standard DIP packages for the carrier board?

  Put any of your ICs into sockets. They're cheap, and will prevent you from damaging senstive parts.

  Hi Matthew,
  
  May I recommend the Basic Stamp Project Board from Avayan Electronics? It is a very economical tool (only $29.95) that includes all which you need to put your Basic Stamp module (has space for a BS I and a BS II) in a socket while gaining access to all I/O pins. It also includes programming ports, reset buttons, voltage regulator, etc.
  
  The link is http://www.avayan.com/Products/BSPB/bspb.html

  One trick I use when prototyping small circuits is to put ICs in sockets as already mentioned and also put on sockets for a handful of discreet components. You can fit 8 resistors or capacitors in a 16 pin IC socket. That way if you aren't completely sure about the component values, you can easily tweak your circuit.
