NTSC Viewfinder ?

Hi everyone, I know I bring a lot of questions and I don't post a lot of instructables (actually 0), but I'm looking for a very cheap (or even free) NTSC Viewfinder for a night vision goggle project , I've found viewfinder on DealExtreme , but it looks like it's not NTSC and it was expansive (from 30$) ... Even a black&white; one will do the job. Thank you for reading

Help with Viewfinder Pinout??

Well guys, I've had this viewfinder sitting around in a drawer for TOO long. I ripped if off an old camcorder in the dump like 2-3 months ago, remembering a few different projects I've seen on here (and other sites) such as: https://www.instructables.com/id/Super-Nightvision-Headset-Hack/step3/Disassemble-the-Viewfinder/ (sorry the hyperlink part of instructables never works for me) I know I've seen a project somewhere online too where a guy used one of these TINY crt's for a miniature arcade machine, just to name an example. I've ran into a bit of a wall here though, it would seem as though everyone else's viewfinders have indivigual wires coming off the board for power and video input. Mine doesn't, it has ONE ribbon connection (although mangled a bit, I still have the ribbon cable that goes with it). This is a really simple looking circuit board, but as I don't exactly have lab quality tools sitting around, I don't wanna solder wires onto it until I know for sure which is for power, I'd hate to fry it on the first time! I tried following the traces on the board but I've never been too good at that, is there some way I can probe around with a voltmeter to determine what is for video input and what is power? I've tried googling numbers off the board and tube and that didn't help either. If anyone can help me power this tube, please tell me!!

I have a panasonic omnimove camcorder viewfinder that I took apart and plugged in and got it running. It is running on about 5.5 V DC, seems to work, but its very squiggly, like the horizontal or vertical hold is off. when I plug in video from my VCR I can see the image, but it is really squiggly. does anybody know how to adjust this? could i have aything to do with the voltage? Thanks!

How can you connect an LCD screen to a YSB001 (MD80 rip-off) camera so you can see what you are filming?

When you film with a good video camera, you can usually see what you are filming by looking at the LCD / viewfinder... but I have bought one of those very cool, tiny cameras that cost about £10, can be bought on eBay and which come from Hong Kong But in return for being tiny, it does not have any kind of viewfinder. I bought mine to experiment with fixing it to my hang glider/microlight to film flights. I figure I can, by trial and error, work out what the actual field of view/ frame is but I'd much prefer to be able to set up my camera with a monitor of some kind (perhaps using my mobile phone camera?) Better still, I would like to be able to monitor the camera all through the flight (perhaps be able to move the mount remotely?) Is there a simple method for achieving this or do I need to do electronics?

Video Camera Viewfinder Screen: How do I Identify Everything and Get it to work? Answered

I recently found a very old video camera and thought I'd take it apart. Inside I found a lot of stuff I can use in other projects, but the thing that interests me the most is the viewfinder. I did some searching around and found out that some people had been able to hack them for use with devices other than the video camera.  My only problem now is that I have not been doing this sort of thing for long and do not know how to go about doing this. How should I go about it? All I know is that there are 4 wires that went from the viewfinder to the main body of the camera: red, black, orange, white.

Can't epoxy metal, help appreciated. Answered

I'm trying to epoxy two pieces of metal together, I'm mixing the epoxy the right way but once it hardens the piece breaks off, any suggestions? I'm gluing this flat piece of metal to the nut that's glued on the viewfinder.  The nut stays on the viewfinder with the same epoxy so I'm confused about why the other metals won't adhere, should I sand the pieces first? By the way I photographed the wrong side of the flat piece, the side showing has prongs, the other side is flat, the flat side gets glued to the nut. This is a viewfinder from an old Mamiya press camera, not sure what kind of metal it is.

CameraEye

I would appreciate any assistance with the following idea. I basically want to duplicate the small VGA viewfinder of my digital camera in a monocle piece for my eye. Would it be possible to hack a LCD viewfinder from one camera (or other device) to input from the VGA cable from the active camera? You can purchase various solutions off of the web, with some monocles in the $3000.00 range! This has to be doable. Anyone? Thanks!

Night Vision Goggle Help. Also cable identification!

 Hi Everyone, I am trying to make my own night vision headset/goggles following this kiplay's guide. I have a electric viewfinder from an old JVC GR-AX5 video camera. I have removed the viewfinder and dismantled it but I am not sure which of the 7 cables are, (i.e. ground, power, video etc). How would I identify this, and could you please go in-depth as I am not hugely experienced in electronics, but I am learning. I have enclosed pictures, if that helps, but I do apologise for the poor quality. As the picture is hard to tell, the cable colours are (not in this order); Black, white, red, redy/brown (i am unsure, i am colourblind), yellow, orangey and a pinky purply colur.  How do I identify them? On a second note, for anyone who has followed this tutorial, can you recommend a good camera to get in the UK? Many thanks, and I hope someone can come through for me, Alex

I need a low cost LED or OLED display of about one inch in size, capable of displaying composite video signals. Answered

I'm planning on building a cheap generation one equivalent night vision system to be used in conjunction with infrared lasers, strobes, and short-range illuminators, and I need a way to display the video coming from camera.I've messed around with viewfinders from older video cameras, but they are black and white, bulky, and worst of all, very fuzzy. The newer cameras I've hacked into have a ribbon style plug that I've been unsuccessful in splicing video signal into (though I did manage to power a few on, or at least get the backlights going). I'm unsure if this is from an inability for the display unit to display the video signal the camera is generating, or my lack surface-mount soldering skills. Does anyone have any links or advice for how to get the newer style video cameras displaying live, unrecorded video from an external source?I've heard that people have had great success with playstation one screens for displaying video without hacking, but they are much too large for my application. My hope is for the entire unit to be housed in a section of PVC about the size of a PVS14 night vision system (2.5" in diameter by 4" long), with a high-sensitivity camera in the front, disposable lithium batteries mounted in a case on the bottom of the tube, viewfinder at the back, and the wiring, voltage regulators, and switches in the center of the tube.I've seen stand-alone LCD and OLED panels for cheap (these come to mind: http://www.4dsystems.com.au/prod.php?id=9) but my understanding is that they need some sort of controller unit to input composite video. Is this correct? I have nearly zero programming experience, just messing around with the BASIC STAMP platform, so how much more knowledge would be required in this area to get one of these units up and running? Are there any tutorials on something similar to what I'm trying to do?I can get commercial night vision in the area of $125, which means that, to be a viable DIY option, the whole unit should come to under $85 or so. With the camera clocking in at about $30, this needs to be a dirt-cheap display.Thanks for your help

I have a USB webcam, and an LCD screen. Is there a way to connect one to the other, and make a digital viewfinder? Answered

I have a USB webcam, and a small LCD screen. Assuming I cut open the USB wire to power the camera, and do something similar with the LCD screen, is there a way to send the camera data to the LCD screen, without using a desktop as an intermediary? In short, I'd like to make a very simple portable digital viewfinder. Given the relative cheapness of webcams (you can buy a half a dozen for less than $10 on google shopping, versus a single CMOS camera module for the same price), I wanted to see how easy such a thing would be to make. As far as I can tell, it'd just be separating the data output from the rest of the wires-- but having never worked with USB before, I'm not sure. Any help?

Screen to use for night vision monocular?

Night Vision

Hey, trying to find a way to get a webcam to display on a LCD viewfinder without the computer in-between so I can mount it on an airsoft gun. I know that the data format for the webcams output isn't reconizable by the LCD screen, I was thinking there would be a way to use a digital camera by feeding it the data from the webcam instead of the camera allready in it but I have no idea how to do that since I've never worked with this kinda stuff. I'm using a webcam because it's easier to open it up and remove the infra-red filter, I plan on mounting IR LEDs to the cam so it has "night vision", them mount the camera on the top of the gun with the viewfinder on the side so you can see. I tried to do this with a cheap video camera since it allready had everything I wanted but the camera module was too small and I ended up braking it. Any ideas? advice? things I should look into? any help would be nice!

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 to tweak CAMCORDERS AS TO CAPTURE VIDEO IN FULL RESOLUTION (uncompressed)?

My camcorder is DVD based, and encodes into MPEG-2 format.  the quality is poorer than the previous model owned by me, a tape based camcorder with same specs. the difference is the storage media, and the villain is the compression.

Half Inch CRT Monitror

I was tearing apart an old VHS camera and decided to rip the LCD out of the viewfinder. Much to my suprise I find a CRT monitor not a LCD! This screen is about 1/2 inch. It has a 5 pin connector that leads to the motherboard and a chip on the bottom that says A118121. Obviously two of the conections would be V+ and ground, but what about the other three? I would like to turn this into a composite or VGA compatible screen (maybe even a crazy tiny oscilloscope) but I need some help. Any suggestions or leads would be greatly appreciated.

Can I make an LCD screen show me what an Image Sensor is viewing? Answered

Hey, I was wondering if anyone could tell me how I could wire up an Image Sensor and a small LCD screen to show me what the Image Sensor is viewing - I know that this is done in Digital Cameras, Camcorders by the viewfinder (I'm looking to make something a bit like that), but I was wondering how I could make a circuit that only showed me how to view what the image sensor was viewing without the extras of taking photos/recording videos.

Using a USB monitor as a standalone monitor for webcam?

So...can this be done? I have a Mimo USB monitor that I'd like to connect to a webcam (sans computer) to use as a viewing monitor. Basically the camera will be used for tele/micro/macro purposes and the image would be sent directly to the monitor. An example would be to attach the camera to a microscope and then use the monitor to view the image, rather than peering into the viewfinder. All this would be battery-powered so that it's usable anywhere. However, I don't have a the slightest clue how to bypass the whole computer thing, as I can't find any info on how the USB monitor works. The Mimo is actually a touchscreen with a builtin video card, so it should be capable of some cool hacking. I have an old usb webcam available, as well as a tiny spycam with RCA out. Questions: Can the USB camera or RCA camera be connected to the Mimo without the use of a computer? Has anyone seen this done before? Anyone have any links/suggestions/experience with this idea?

Magpul PDR

Here's a project Trauts and I are working on. Trauts still has to fine tune my version. I was actually only going to build the back and firing mechanism and leave the front to trauts and have him mod whatever needed. I just added a front on for the heck of it. Here's what the PDR is http://www.magpul.com/pdfs/PDRtech_PR.pdf I had a video but it wasn't working so I'll just have to explain some of the features for now. This version wasn't made for looks but just to show off the trigger, magazine, and mag release. So understand that this is by far not the final version. Alright to explain some of the features now: - I made a quick adapter for rail accessories from airsoft and maybe real firearms. The adapter can then attach to my K'nex rail. I used this very low quality red dot scope for an example. I wish I had batteries for it so I could at least use it as something more than a viewfinder. -The trigger is complicated looking but it's pretty basic. I took my old bullpup trigger (could probably be used to all kinds of bullpup weapons) and modified it a little so that I wouldn't need such a long barrel. To do this I brought down what normally would be the part you'd pull and placed that early and then made a sliding trigger that pushes that part back. It's actually pretty reliable. -The magazine is a somewhat new design (that or hardly ever used) that is really close in size to real STANAG magazines. The real version doesn't used curved magazines but I decided to make a curved magazine anyways to demonstrate how to make a gently curving magazine for guns like the Magpul Masada. You can lock the mag pusher down if you're using a weak enough rubber band. -The mag release isn't what's used on the real one but it would be impossible to make one like that. This is pretty simple but very effective. It's just a little lever switch that you pull back and the magazine will pop out. You put the magazine in firmly and you should be able to hear it click. It's rock solid when locked into place. I'll show you pictures of it later.
