wireless accelerometer interest

From Wear-Hard Mailing list Archive (WH) Maintained by R. Paul McCarty

I'm trying to gague interest in the wireless accelerometers our group
has developed. We're investigating a production run of around 100, to be
sold for under $100 each. Here's a variety of information about them,
and the website where more information can be found. If you're 
interested, please send me an email with how many you think you'd order
when they're available. If you have a specific project in mind, a short
description would be appreciated as well.

Thanks,

Overview

  This is a small wireless sensor platform providing a bluetooth SPP
  link to three axes of accelerometer data.  The accelerometers are
  sampled by a PIC microcontroller (onboard ADC) at roughly 100Hz
  (rate can be changed via firmware).  Data from the ADC conversion is
  sent to a remote computer using the PIC's UART in conjunction with a
  drop-in bluetooth serial part.  Even with two dual-axis
  accelerometers onboard there are up to 17 free I/O lines and two
  additional ADC channels depending on the device configuration.
  Three sockets provide access to all PIC signals.  Over-the-air
  programming allows for easy firmware updates and rapid prototyping
  without the need to have a PIC programmer or special cable.
  Schematics, parts lists, and firmware sources are available online.
