Engineering - November 2006

im just a kid who wants to build a really simple robot. i dont really carewhat it does at all, beacuse it would be cool to me in amy way.well ive seen a really simple one before using these : 1-2 bottle caps, a battery holder ( probobly not what its called), 2 batterys and one red and green wire. the result was when you put the wires togther, the bottle caps spun and it would move around the table.

What is the maximum distance those types of signalers work and what type of wave to they transmit, infrared? I have an idea for a pay-at-the-pump type swipe device but it would be a click button type thing instead, but wondering if that technology would allow for just one receiver within the station building instead of receivers at each pump as is with current 'swipe' type pay keychain fobs

so the question is how does that car alarm tech work - because current car keyfobs are not "random" enough (ex. one may find their remote operates another car, although the key probably wouldn't) the encryption would have to be more specific than current car alarm type

and what is the maximum distance those types of receiver systems can cover? and what about obstructions/reception issues>

thanks
