Post your components of unusual physical size
« on: May 29, 2011, 12:39:28 pm »
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.

A CRT view finder ? kind of smacks in the face of being told as a kid to sit a certain distance from the screen  ;)

Neat! Controlling that would be an interesting project.

Yes - would be rather tricky making a shadowmask tube this small...

Not 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.

Hi John, I suspect that big bugger was built to supply traction motors such as those used in electric locomotives or shipping, the volts and amps ratings looks about right.
You can do anything with the right attitude and a hammer.

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

Here's two ultra tiny meters next to a NZ one dollar coin.


I used to have one of those that I pulled from a defunct philips cassette player.  I ended using it in a QRP SWR meter I used to tweak antennas when I used to backpack radios out into the boonies.  I remember it using a 1mA movement.

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.
