The Pin Clock. Clever eh? £50.00. [Thanks Jose]
Remember those pinboards that moulded an impression of your hand? Well, this clock uses the same technology to bring you the time, without the hands… Housed in a modern metal effect casing, solenoids push the pins out with a satisfying staggered click.
I have one of these, but the batteries seem to run out pretty quickly. Any other owners observe the same thing?
it would be interesting to make device with similar pins for
displaying with 3D functions in mathematics
50 pounds? They sell them for $20.00US at my local Circuit City.
Hah, cheap pins. :-)
