Wamco KW-105AL

http://vimeo.com/28564327 Here is another eBay find that I thought was worth sharing.  This is a Wamco alphanumeric minitron display.  It is similar to a numitron in that it is also an incandescent filament display but the packaging is significantly different.  I believe these devices were primarily used in aviation because of their resilience but I'm having troubles backing up that belief with hard data.

Driving this device is easy - there is one common pin and the remainder of the pins correspond to a different segment in the display.  I was powering these with 3V but for those curious, the full data sheet for the KW series in PDF format.
