  2 questions, does it have cogs? and what is the wireless for? could you listen to radio? or is it just like parallax's 433Mhz transivers? and could you even use this as a stepcounter? to be simple

  It uses an MSP430 chip, not a Propeller.
  
  It transmits data to a PC equipped with a similar chip and USB interface, and can receive data from the PC, using the 868 MHz ISM band in Europe. It has an accelerometer, and could be used as a step counter if it was kept in a trouser pocket, with suitable software. ADI has an app note on a pedometer design using an accelerometer attached to a thigh.

  parallax Needs to sell a BS2 or prop watch . I know I would love to tinker with a Open watch with IR IO's and various sensors ( acccel , pressure , temp , compass, ect) built in .

  They'd use too much power, devices like the MSP430 or the new XLP PICs are much more suitable.

  I have ordered the ez430 dongle to play with.
  How wrong can I go for 20.00
  
  I was thinking of using a 430 chip in a little project of mine
  but have decided a 5v part from microchip is a better choice
  since it is just as cheap in 1kb flash version and saves the cost
  of a 3.3 regulator. I can't believe I will have to set up to work
  with the PIC chips again. They were the first chips I ever played
  with, only a few years ago but it seems like ancient history now.
  I don't think I packed my old PIC programmer though, dang.
  If I remember correctly it was called the diy150 kit or something
  like that. I could get a cheap serial port programmer but I only
  have my laptops here and no serial just USB.

  Get a PICkit 2 (if you can find one) or the newer PICkit 3; they are quite cheap and you get debugging as well as programming. I have a PK2, but I mostly use the much more expensive ICD 3.

  Brad posted some tutorials on www.bradsprojects.com on how to use the Pikit 2 and he has settled on only two chips.· He is rebuilding his site so it is a matter of time before all of the tutorials are up.· He has reposted tutorial 4 of 7.
