Hey my friends! *
I have a new idea for something really cool ;D
But first things first - the story:
My wife had her birthday last week and I went out for dinner with her. We went to this really nice vegetarian(!) restaurant called Vegetaria (http://www.vegetaria.de). The dinner was more than perfect - I didn't expect a vegetarian menu to be that delicious!!
So, this restaurant is one of the stylish ones (click on "fotogalerie"), with rare decoration, no pictures on the wall and so on. But they had a light spot with their logo pointing to the floor. That was a really beautiful but discreet thing.
Now - can we make such a spotlight with a pattern in front to get a picture on a wall/floor ?
As I was in town anyway, I bought a LED-bulb today. One I hope does not heat up. so I should be able to mount something in front of that spot.
What do you think ??? is it possible?

Tux - I'm sure it can be done, it's just a matter of figuring out how. i.e. distance between light source and pattern, distance between pattern and wall/floor, amount of light necessary to carry the silhouette to the wall/floor with enough clarity to recognise what it is. Probably a lot of trial and error, but as exemplified at the restaurant, it CAN be done.

Hi torsten,
What a great Idea.
did some searching on google.
what you want I think it's called GOBO
To use LED instead of traditional light will be better together with wood. because LED doesn't get so hot.
at a German website I found a gobo-top:
http://www.grafiklicht.de/en/sortiment/gobotop/gobotop.php?level_01=sortiment&level_02=gobotop&level_03=false
maybe this is what your looking for.

whit a bit of creativity you should be able to make one.
some of them Gobo's are great saw patterns to. just found me a new way to search ;)
-
ah - thanks! That's cool. I just knew the lights the restaurant uses are from Erco (http://www.erco.com).
Hmm, time for another prototype I think...

oooh...show us, show us!!!!

Yes Yes we want to see the prototype.
You gave mean idea for craft shows and such (outside craftshows) for inside of my tent..

Hi Torsten, I make lighted Coasters using "Puck" led lights I googled Led lights and found them. They use 3 aaa batteries which last for a long time. Some stores carry puck led's under "as seen on TV" These lights sell for Three lites for about 10 bucks. I cut a round disc 1 inch thick and 4 inches in diameter and cut a 3 inch hole in the center where I place the puck. (you push the lens down to turn it on/off.) I have cut a colored clear plastic lens and put it so the lits shines thru it. If anybody tries this I recommend that you turn it on and place a glass or mug or blown glass on it. The effect is unusual. For example I put a green lens under a glass of beer and get green beer for St Patricks day

maybe you could make it with a rotating disk

oh, Marcel . I don't know if my wife likes our living room turning into some disco dance floor....
@ frank
please post some photo, this is not what I wanted to to build - but it seems to be a pretty cool idea!

Don't forget this! ;D
I know, I'm not being helpful, but I just can't resist! :D

*lol* there we are again, has Malc found a way by now to build a hollow globe?

This goes out to the people in the states because they will remember these.
I think what he is looking for is an idea of an over head projecter like the kind from school same idea on a smaller scale if this helps any....
So does anyone have any ideas like that..
-
oh, Marcel . I don't know if my wife likes our living room turning into some disco dance floor....
off course didn't mean with the colors, ;) but imagine that you put 4 gobo's in one big disk and then let it turn slow. ::)
I know that at IKEA they have there logo on the ground and that is moving around.
a dynamic light that changes every now and then.

A matter of 'physics'...Light 'diffuses' the further it gets from the source unless 'focused' by a lens of some type. Think 'movie/slide' projector...you can't put a light behind the film and project it at a distance without a lens.
There will have to be some kind of 'lens' or 'point' light source to hold the pattern of the projected image from the ceiling to the floor. Otherwise the light will simply pass through the 'pattern' and diffuse and render the pattern unreadable at the floor. You may see an fuzzy general outline but it will not be defined enough to be 'accurate'.
The Physics of Light 101...
No charge for this course!

Great idea Tux. I have made a few shadow lamps for people it works on the same principle I think. It casts a pattern on the ceiling and other walls once lit. I cannot find the name or pic of the light to use as I forgot the name ??? But the light bulb is coated or something with silver on the top this helps against the heat close to the wood and it is not as bright as a normal light which gives it a suttle touch. If I remember the name I wil let you know.

Hey!
right, GB, that's a point to consider. Will I need a lense ??? hmm, I'm gonna make some simple pattern and try around. Right after I have finished the other stuff occupying my shop :-\
@ Dawie
Do you have pics of that?

Hi Thorsten, My computor has a problem, it won't send attachments Therefore I haven't found a way to send pics Frankm

Hey Tux I just found this on YOU TUBE so have a look you may be able to expand the idea behind it.

That is a pretty cool Alien Projector there Chachi. Nice find. :)
-
I thought it was kind of cheesy myself but the idea is there Hook up the light in back cut out the wood to whatever shape he neededand follow it from there I may try that idea myself when I get a new saw Just not with the Alien I figure mine and the wifes names in a heart or something.
-
they didn't use a lens,
I think that the length of the tube already "align" the light beam in one direction.
what would happen if the tube was shorter, would it make the image more blurry?
-
hey!
Thanks, Chachi, that's for sure a good idea.
Sadly I haven't come with a first try yet, had to struggle a bit with a flu the last days.
@ Marcel
hmm, I think it will increase the ratio of size/distance.

OK, had some time to try some:
(http://www.torsten-harms.de/holz/globo/firstTry1.jpg) (http://www.torsten-harms.de/holz/globo/firstTry1.jpg) (http://www.torsten-harms.de/holz/globo/firstTry2.jpg) (http://www.torsten-harms.de/holz/globo/firstTry2.jpg)
It works!
The light needs to be directed. The beam should be as narrow as possible. In this test I used my scroll saw light (LED, narrow beam). The pattern also needs to be small - the smaller the pattern, the nearer it can be placed to the light source.

Looks like you're gettin' it figured out Torsten! Expect to see a working prototype in the near future! ;D
