RE: [PSUBS-MAILIST] Joysticks

Regarding heat:
I like what someone from the list had called water before... the
infinite heat sink.

Regarding keyboard (previous email)

Sweet flexible keyboard.  I wonder how it is to use. 
Another site for watertight keyboards is:

Hi,

You're right, it probably isn't that hard as I thought to make it 
waterproof.

Hey, that will work! You can make a watertight box (you probably should
use 
regular desktop parts though, they're cheaper), put it _outside_ of the
hull 
and actually use water for cooling (run bronze piping inside). Water
cooling 
has been done and it's very effective.

Sincerely, Paul.
