I know most of oyu prolly don't read these....but well..soemtimes I am just
thinking and come up with neat ideas...(or atleast i think soem of them are
neat)
Idea 1:
I was thinking about projects in old magazines (electronics now etc.)
and i remembered once seeing a wireless voltmeter which used the human body
as its return circuit....now...my question is this...you can drive the
inputs on a parrallel port with an optoisolator right?...so why cant you
build a small circuit which drives those optoisolators by using the human
body as a ground....taking this a step further....put conductive patches on
the tip of each finger and three on the thumb (three thumb keys) and by
touching any bare spot on yourself you can type....you can type by touching
your fingertips together....touchign it to the side of your face etc
etc....VERY covert! (except for the conductive patches)....any input on this
would be interesting...
Idea 2:
put a small graphics LCD on your wrist and have it tied to a tiny
computer...this computer would be interfaced to your wearable...this way you
could have alerts (such as new mail etc.) coem to the LCD...now to take this
a step further....maybe incorporate sensors (say a temperature sensor and
maybe some sort of transducers etc.) on your fingertips.... and patch them
through the LCD on your wrist with an option to log it on your
wearable....the possibilities are tremendous....and ultra sensitive
transducer may for example allow you to hear someone's heart beat (and maybe
display it on the LCD along with their temperature)....or to listen through
walls....but the whole thing is using the LCD to alert you when you have new
messages or something and give you a basic overview (subject line etc.) of
the message so you are not tied to a HMD
maybe these ideas will help someone become inspired...I know I/O freaks
might like the sensortized glove....:)
