content: So you have some electronic component or test gear which is either unusually big or unusually small.Post it here so we can have some laughs.Here's two ultra tiny meters next to a NZ one dollar coin.

content: Quote from: Hero999 on May 30, 2011, 06:45:04 pmYes - would be rather tricky making a shadowmask tube this small...QuoteNot much point as the viewfinder usually contains all the drive electronics and just needs power and a comp. video signal. Unfortunately it doesn't look as cute once the scan coils are on.

content: Here's a massive valve from an old high power transmitter. I believe it was used at an airport.Quick google found this info"Eimac 450TL, measuring 12.5" tall by 5" across the bulb. This is a directly heated triode transmitting valve, 7.5V/12A filament, 4kV to the anode."AA battery shown for size

content: Not a component but I have always been impressed with my old Sony WM-101 walkman cassette player.With the flat 'gum-stick' battery pack it is exactly the same size as a plastic cassette case.I often wondered what the guy sitting at a drawing board designing the plastic cassette case would have though if someone told him they were going to fit a complete auto-reversing player and battery in the space he left behind.
