I've recently been to a local arts and crafts shop and they had packs of square mirrors on discount for an insanely low price of 49 cents a pack of 25, so I bought 5 packs which each have 13 tiny square mirrors and 12 mirrors twice the size. I've attached a photo of them.
Anyways can I easily construct a mirror drum TV with square mirrors or do they have to be rectangular according to the picture ratio eg. 4:3?
I've been thinking on having a crack at a mirror drum TV for sometime, now I have mirrors I am gonna try making one

I had a go some time back trying with a laser infact using the mirrors you are //
I shouldn't of given up as it would of worked if not for the fact i didn't understand the electronics before the laser diode filtered out the NBTV video signal /
i ended up junking it for a different idea in the end which you can have a look on my you tube site .
A better idea for mirrors drum mirror wise is plastic mirrors you can cut out with a stanley knife you can get if not sheets some thing shape wise to cut out from spotlight .
The trouble with glass mirrors is if they come off at speed which they did for me once or twice and its not good ! in the end i worked out if i could not pull them off by hand i was safe
Which ever way you go a laser pointer is a good tool if you end up doing a angled mirror drum .
Again remember you don't want those glass mirrors flying off at high speed in your direction !
The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.
