a DIY optical port

I have been intrested in optical computer for a while but found them rather expensive to build so I tried to look for cheaper ways to build some key features like the gates. The basic idea is to use solar cells that power a led. For and OR-Port you use solarcells where it is enough that one of the side gets light to make the led burn. To make and AND-port, you can put a resitor in between so that it really needs the power form both channel sot make a led burn. For a NOT-port you put an invertor in, so that when it burns it gives no signal, and wheren it does not receive light it burns this because of a battery it caries. A NOT-port is almost like a led-throwie.I do hav emore but wanted to know if this would be a good place or not, or if someones intrested in hearing on how to build a full optical computer, still basic, but almost completly optical, or if it would be better to post this on the microprocessor group at the opencourseware of the MIT ?

Plastic Optic Fiber

Hi, I made a lot of research in order to find some plastic optic fiber in europe, and I finaly add to buy some full rolls of the one I liked. It it PMMA fiber with 0.3dB/m light loss, it polish well, and when use with long length, gives a sligher yellow / green color to the light (noticeable on white light, but really lower than the other I've tryed). If someone need some, I can make a kit with : -27 meters of 0.75mm diameter -15 meters of 1.00mm diameter - 7 meters of 1.50mm diameter I think thati ncluding shipping to anywhere I can send it for tens euros. If someone is interested, let me know and I will check shipping price and paypal fees. Regards, tReg.

Optical Image Stabilization

Hi everyone, I have a little awkward question here but I am sure someone who knows a little bit more about electronics can give me good advice. I took apart the lens from a consumer video camera and took out the Optical Image Stabilization module in an effort to figure out how it works and possibly hijack the signal so I can control the movement. In the camera this module is getting the signal from the accelerometer so it knows how to engage the two electromagnets and counteract the movement (shaking). What I have done is take the leads that go into it and try to fake what gyro sends to this element. So far I have noticed that when I short 1 and 2 or 3 and 4 the element goes to one side or up. So I put a potentiometer on it (2K ohm) and it gives me some control by turning the dial, but not good enough. Has anyone any idea how can I achieve a gradual movement of this lens element vertically and sideways with a slider or dial of some sort? Your help would be greatly appreciated!

usb over fiber optic cable

My house was once part of a business that was connected to neighboring structures via fiber optics for Internet.  I want to put in a security system with some usb cameras and of course we know what those limits are.  I have successfully made 25' usb/cat5 cables using this site... they work great but I need 50 - 60'.  I was wondering if it was possible to utilize these fiber cables for the data side of the usb and somehow power it by other sources?  I know a little about fiber like putting in connectors and such and I do have 2 transceivers.  I can make rj45/usb connectors for the tranceiver ends but I'm just not sure of the details or even if I'm barking up the right tree.  I'm not sure where the power fits in either. Any of you geniuses know how I could do this? Thanks

Mechanical and optics help needed for camera tinker project Answered

Hi, Some time ago I acquired a beautiful old bellows plate camera, quite closely resembling the top one on this page. Mostly I try to use old cameras with the film they're designed for, but plate photography is going a bit to far for my tastes. Therefore I set out to convert the camera to a digital one. Something like the SVP FS1700 seems perfect for turning into an improvised digital back, but I think I'll need something to look through and focus as well. I've made a quick sketch of what I think would be a good construction, it can be seen at http://www.incarnations.nl/temp/camera.jpg. (1) and (2) are mirrors, projecting the image on the ground glass plate in the camera to the viewfinder on top. When the camera has been aimed and focussed, mirror (1) can be flipped down, allowing the scanner (3) to take the picture. I'm a kinda decent tinkerer, but I've got no experience with lenses, mirrors and the like. A couple of questions I'd like to have answered: 1) Does this have any chance of actually working? 2) What would be the best way to determine the proper placing and angle of the mirrors? 3) The distance between the scanner and the glass plate might cause some focus problems. Could this be worked around with lenses or an extra ground glass plate, or will this cause more trouble than it's worth? 4) As an added bonus I'd like to add split-images focus to the viewfinder, but I have no clue how this works. It can't be as easy as just buying the prism/glass and inserting it into the viewfinder, right? Any help or advice anyone can give me would be greatly appreciated!

How do I make 2 or more objects light up when they come near each other, or get brighter, or change color? any ideas?

How do I make one or 2 objects(I have in mind small objects) light up when they come close to each other? or brighten or change color? Some one suggested proximity sensors. But then they would react when anything came close. He then suggested using magnets in some way so they would react to each other. I have a lamp that turns on when you wave your hand over it. If you place your hand close to the top of the container then slowly raise it the light will brighten, then dim as you lower your hand. Not sure if that is related to my quest, though I am interested in that also. Any ideas?

Parallel beam of light out of biconvex lens f=45mm

Hi, I would like to create an almost parallel beam of light with an LED and a biconvex lens. Therefore I have to place the LED directly in the focal point. I thought of a setup with a PVC pipe with threading: I could glue the lens to one end and screw a cap onto the other. Then I would drill a hole in the middle of the cap and stick the LED through the hole. By screwing the cap back and forth on the PVC pipe I would be able to find the exact focal point and then fix the cap in place. There is just one problem: Lenses are either incredibly expensive or only available as sets. The only exception I found so far are lenses for google cardboard. They sell for just a few euros on ebay. Google cardboard lenses have a focal length of 45mm and different diameters, I would like to use a diameter of 25mm which is no problem. Now I wonder: Is the focal length of 45mm too small ? Will I be able to get an (almost) parallel beam of light out of this setup ? The LED is no ideal point light source. Originally I wanted to get f>80mm but that is really expensive. Anyone with experience on this kind of setup ? Tips you could share ? Can I get this to work, or will the approach be too unprecise.

How to use Fiber Optics?

I am making a super-discreet earpiece/IEM that is intended for any use where you feel bored, where you are not supposed to use electronic devices. Meetings, lectures, classrooms, etc. Basically, it's a 3.5mm jack wired to a Balanced Armature driver. Essentially, I remove the big, thick and bulky housings of earpieces and leaving the smaller drivers in place. I've been using thin copper cables in the earpieces I buy. They work, but are still visible. I found that optical cables are near invisible, glass-like. I intend to wire them into my earpieces. So, do I require lots of circuits? I can do those, if they don't poke a black hole in my wallet. No more than USD100, if entirely possible.  I just want to know how to change electricity into light and back again, and allow for audio transfer from MP3 player to earpiece drivers.

So since I am using" an and "gate I want the input current to be an absolute zero or some value ,ie the current should not be varrying with the light intensity. Besides I think I might drop the "and gate" thing and use an OPAMP instead as it would give me a varrying output current which is all I need

How do I arrange optics to make a decent periscope? Answered

Ever since I watched the first season of Stargate SG1, I've wanted one of those sweet little tactical periscopes that Jack o'Neill uses to look around corners to avoid Jaffa. The image is here, but it's just a prop! As far as I can tell, they either don't exist or are absurdly expensive or are just really hard to find. So I want to make one. I know some basic optics from working in a university laser lab, but we don't usually use lenses and such. I have played with simple two-lens telescopes and know that the ratio of the focal lengths is the amount by which an image is magnified. The corner would need to have a tiny prism in it. The problem I'm having is this: If I use tiny lenses, and a longish (~30cm) tube, the viewable area is ridiculously small. I would love to find a way to enlarge the viewable area I see in the eyepiece. Does anyone here know how this is done? At the very least I would like to know how to position the optics so that it seems like my eye is at the far end of the periscope. Maybe I could use a peephole lens to get a wider field of view too.

fibre optics

Hello, Hope to find here some information about Optical Fibres. I am building an under water housing for DSLR. I want to use it just under the water surface. Controlling (through an air bridge) and exposure (through optical light guide) are on land. The question is about optical fibres. I need a 160 cm long Fibre Optic Lightguide. A 1/4 inch diameter guide costs near 200 GBP. When I would make one myself of 1/2 inch diameter, I could safe 75 % + the entrance surface is more than 3 times larger, which is important, since I will have to guide the light of a flash gun! BUT, I doubt wether such a diy bundle of 1,5 mm diameter plastic fibres from ebay will give me roughly the same or preferably more light output as/than a professional guide? How do these plastic ebay fibres compare to professional or glass fibres in terms of light transfer efficiency? Any suggestions? If not, then a reference to another forum where they might be able to answer my questions, would be much appreciated.

Telescope repair advice wanted: UPDATED!

This question is more like 2 questions- 1) Am I crazy? 2) Is this feasible? Background: I recently inherited an astronomical reflecting telescope, which I think has been dropped at some point.  The design is as below. Where the eyepiece enters the side of the tube that makes up the body of the scope, the tube is slightly dented.  The eyepiece still points at the secondary mirror and the alignment is good enough that I can point the scope at an object and get an image, but the alignment isn't perfect so the image has a lot of what I'd guess is spherical aberration preventing a decent image. Firstly- is having the eyepiece on-axis and perfectly aligned so important that I will never ever get even a half-decent image from this scope?  If the tolerance involved are 0.1mm and minutes or seconds of angle, I doubt I can restore it that well. Secondly, is having the eyepiece positioned on-axis as important as having it parallel with the ideal axial light path?  As it's held in with three screws I'd imagine I can tweak the alignment with some use of spacers etc. but if it's off-axis I don't think I can shift it back to the perfect position.  In other words, for the mathematicians, is having the eyepiece "translated" as much of a problem as having it "rotated"? (Thirdly- if the reflecting scope is trash, can I get a 150mm diameter 1000mm focus lens and make a straight-through scope with the bits?) UPDATE: it's working perfectly, see pictures below!

What to make from ridiculous Zoomies glasses

So I just got some of these ridiculous glasses from my grandpa. They are advertised as hands-free binoculars, and claim to solve all those issues you had with normal binoculars (?) Anyway, they are terrible, their lens quality is crap, their focus sensitivity is terrible, they are uncomfortable, and make you look like a complete fool. Anyway, ideas about what to make with these things? Might as well make something useful with them.  I was thinking a pair of opera glasses, there are three sets of lenses in the goggles. The plastic frame and focus assembly are pretty weak and can't support much, but could be steampunked or something.  Any ideas appreciated.

Take a look at this! 2 parabolic troughs combined to make a point focus!

Http://www.youtube.com/watch?v=FYzgYI9_h6s is from a Swedish mathematician.He bounces light from one trough to the other to produce the point of light. Even if it is not as efficient as a parabolic dish (2 reflections instead of 1) it must be easier!He is just curving sheet material. I have made parabolic dishes and it is really hard to be exact enough and it is really hard to get the reflective material to go onto the dish without crinkling. So under "real life" amateur conditions, his apparatus is likely to be as efficient as a home made parabolic dish!He has more info http://www.youtube.com/user/MathRehab and he has pdf files to download too.Great Idea.
