Hi,
I wonder if anyone could help,
i'm trying to make a pressure sensitive unit,
i dont mean air pressure,
i want the resistance to change when i squeeze it.
Like a pressure pad, but much bigger.
I intend it to vary the current to a 12v headlamp.
From dim to bright, or better.
I have tried powdered carbon from battery middles,
it jams up.
I tried including powdered rubber mixed in with
powdered carbon, got nowhere with that.
I tried layers of wet paper between layers of metal,
that stunk bad and didnt work.
If anybody has any suggestions, i would be happy to
try them.
I would think its an easy thing to make.
It would have to be capable of being squeezed and
changing its resistance, then when its released,
changing its resistance back again,
I will be trying powdered up sponge mixed with
powdered up carbon rods from battery middles,
between plates of metal.
Somebody might already know the best materials to use.
Regards, John
