oooh shiny

[Harvey] wrote in to share the Spindicator with us. The spindicator is a hard drive activity activity indicator built in a ring to resemble a dekatron. Using the pulses from the hard drive activity LED, [Harvey] tested several different methods of interpreting that data for display. The final version, negative edge triggered with a lowpass filter can be seen after the break.  It is nice and smooth and vaguely reminiscent of many programs’ loading screens.

He has pictures and tons of detail on the project including videos of previous versions that acted quite erratically.
