Hello,
I will try to repost my photos (I will give you a picassa link) and also add more information. Can you give me a description of what you used so far? Also, what is the working distance for your loupes?
I am now upgrading my light with a new led, new power source and driver.
I will use a micro buck/boost configuration without dimming and a 5 volt usb rechargeable battery pack. I will order the parts soon. I will also make my own loupes (or try to).
If you have any more questions please post them.
Actually at the beginning i have bought this torch from an ebay seller:
http://www.ebay.com/itm/170663654616?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Then I took out of it the cree led, the driver, the aluminium heatsink and the plastic lens, just to make it all smaller. Then, i managed to find an old broken fiber optic headlight system in some sort of technical garbage of a hospital. i took it apart, and took out the lens and the diaphragm out of it to play with all parts i got from those 2 systems to make the best possible headlight out of it
The red arrows indicate the parts i have used for the torch seen on the 3rd photo.
it's battery pack (just a plastic box i found to hold 2 AA batteries), Silver heatsink, black part of a tube, smaller lens with the diaphragm, large lens (both Glass), and the cree on the aluminium plate, connected to the black cable which leads to the driver which is hidden in the battery pack.
As you can see, it's very primitive and alot of work is still ahead... I have fixed all parts including the lens with this white tape, The long size of it is because of the optical needs, i had to move the lens to a certain distance to maintain the focused beam. now if i could find better optics for that matter, i'm sure it can be alot shorter and lighter. (there are 2 lens in the system right now, unfortunately i can't tell its parameters because i simply don't know. i just got it out of the headlight i found)
I am using Heine HR loupes x2.5 420mm. and the beam i somehow got is exactly the size of the area seen in the loupes while in working distance (420mm).
Tough project :duh2:, as Theodore Herzl said: If you will it, it ain't no dream
i have bought some 23mm glass lens in
www.dealextreme.com but i don't know if it's the right angle i need. i just hope to test try it instead of the smaller lens,and i hope it will shorten it's size... i will definately continue updating the progress, come on it has to be done somehow
! no way Heine light cost 1200Euros and is made of diamonds. it's the same cree, pretty much the same optics, only different sizes.
