Spice Low Power

[Paul Dale]

It sounds like you are wanting a tricoder.

I would love to convert an old HP calculator to do this. My unrequited wish list would include:

• GPS receiver
• Accelerometers (often comes with the GPS)
• Gyroscopes (often comes with the GPS)
• Magnetometer (compass, sometimes with the GPS but often useless)
• Temperature sensor (sometimes comes internally with the above sensors)
• Real time clock (can be ignored with GPS fix)
• Barometric pressure sensor
• Relative humidity sensor
• Geiger counter
• EMP sensor (lightning detector)
• Gas sensors
  

A classic might have space for these, although the power requirements of some would be excessive (e.g. gas sensors usually require heating and often a lot of space).

My (at best) negligible hardware design skills are an impediment. As Bernhard essentially noted, talk is cheap.
