Projector Optics

[tomcat]

i dismantled a aincent projecytor today and have some nice FS morrors some dichromic 50/50 mirrors some colour filters and a rgb thrchromic prism combiner.. dont know what to do ( gona sell eventually) so anyone need any of these??

Full stuff:
1large 2"by4" fs mirror and 2 a smaller 1"by 1 1/2 " Fs morror
3 dichromic mirrors reflect light 45degree pass through 0degrees that change pass colour with angle SOLD

SOLD
a reflect blue pass red
a reflect yellow pass blue SOLD
a reflect all pass blue

3 colour filters 1inch by 3/4
pass blue reflect/block yellow(yellow+green)
pass red reflect/block cyan(blue+green)
pass green reflect/block purple(red+blue)

a number of lenses with various focal lengths
2 flat-convex shallow 1" round 1/10"deep
1 flat-convex deep 1"round 1/6" deep
2 "fat" ones with 2 convex sides 1"round 1/3"deep
a large fairly flat one that has 1 flat side and 1 very shallow convex side 2 1/2 round with cut sides 2"
a large flat side- convex side one 1 3/4 round 3/7" deep

and finally a 3-->1 combiner
out

and a shitload of 450v
100uF caps that im keeping for my railgun project

what kind of projector was this? sounds like it has some cool stuff in it. Bet it was fun to take apart!

im interested in the combiner pm me a price

it was REALLY old the caps are huge and i got my railgun fireing pencil lead through a sheet of paper at 2m 60000uF at 400v FTW

i still have to dissasemble the lens to get all them out

or 0.06F - your parade is hereby rained on.

bah i know there are bigger caps but for free without resorting to collecting old disposable cameras its a good figure

or 0.06F - your parade is hereby rained on.

yes, the number indeed is less long. in fact i was more impressed after reading it, i didnt convert the uF number to useful numbers. 0.06F at that damn high voltage is really impressive. if you cant kill that bear with the pencil leads, let it touch the capacitorbank.. hehe
oh, goldcaps are in the farad area, since years.. at 2 volts per piece only!

well i have now mounted it all in a handheld with a bank of battaries ( 12 AAs) in sets of 2 (3v) linked to 2 camera cap chargers and a few more caps ( now 0.1f) at 400v with about 5 sets of rails made up (they like to turn into blue plasma) and im trying to get it to fire without just vapourising the graphite and turning it into a bright lilac plasma ( white for graphite and blue for aluminium) im thinking of making my own procectiles ( must be under 2mm wide) im thinking of a bunch of 0.7mm ( mechanical pencl) and wrapping them in the filament from incandecant lights ( tungsten) so the tungsten blows and the leads are left flying like a mini flechette gun at 300-800mph and get a normal one wrapped also in tungsten OR get some brushes for a small moter and make a bigger rail set i tink it will fire even 20grams at least 60-70 mph

guns are illigal in the uk homebrew "lorents force acturators" are not
