Night Vision Scope Camera
So far the most economical option I have found for cheap night vision would
be to use an automotive backup camera with monitor, Amazon has them for $30 range with free shipping. The camera's should already have the IR filter removed because they come with IR LED light source. On topic, machining required for camera mount to scope and monitor mount. The system is set up for 12V power and has cords for camera and monitor. These should be able to be powered by 3 lithium cells in series or other 12V power source. Add a good IR flashlight and optional IR laser sight for invisible night time shooting/pest control. RogerN |

If you are trying to use any of these cameras to look into the scope...keep in mind the focus range is only a couple inches. Many of the common NV cameras will NOT focus less than several feet, with the lenses that they come with. So you may have to machine an extension for the lens to bring focus up close enough to be usable on the scope. Hanging a camera on the side of the scope simply as a view finder...will not do you a bit of good. You MUST use it to look into the scope itself. Gunner |

Fortunately..Im not you and can find my ass with either hand...and without a handler giving me directions. Something you are obviously incapable of doing on your own. Did you scrounge up the $300 to get Hotel Econoline out of the repair shop yet? Crom yes..did that a couple weeks ago. We found that the grind shop had not ground one of the journals properly...we think..so I went down and bought some Plastigage this morning and took it to my mechanic along with a calibrated bore gage. No word on the results yet. When he installed the crank and main bearings .....he found it to be a bit more "sticky" than he thought proper. Might have to go back to the grind shop for a rework..the *******s. It took em nearly 6 days too long to grind the crank and they gave it back ground -.-20 instead of the -.010 it should have been..I mic'd it...as did the mechanic and the grind shop when I sent it in. So while it MIGHT be an out of spec bearing...I bought King SI bearings ...so they should be good to go. So they ****ed something up. However with a bit of luck, it should be back on the road this weekend or early next week. No work this week (so far) but have a few dollars in the bank so will be able to get a smog done on the E350 as soon as its completed...the shop thats doing my work is a smog test station as well, so thats covered, and Ive already put it on my AAA insurance, to be started the minute I call my agent. Then we do the heads on the Ranger. Now dinner is done, and its back out to the shop. Im doing my spring cleaning. And surprisingly..I found (2) wild kittens in my motorhome. No idea at all how the momma gets in and out of there, but they are fat and sassy. Took my wife and I about 30 minutes to tame them down and get them sleeping in our laps. Ive ordered a tranny for the motorhome and that should be here in a week or two and that beast will be back on the road after a 12+ year vacation. Finally. At long last. Crom! Anybody want a very old, but still running well, 300+amp DC only Hobart Brothers welder on its own trailer? Just want a couple hundred bucks and someone to come get it out of the back yard. It ran well the last time I fired it up, but its taking up way too much space back there. It needs a battery and a fuel filter bowl, other than that...it would make a good field machine for occasional use. Ive got a decent Ranger 9, so really dont need this old girl taking up space. https://picasaweb.google.com/1040422...GasolineWelder Ive also got a Miller Trailblazer 55G that needs the engine rebuilt. Its all there, just needs a set of rings and a good hone job and gasket set. IRRC...Ive got a brand new set of valves for it, and I may..may have a new set of rings tucked away. Continental F-163 engine, same one in most Lincoln SA-200s and a bunch of forklifts..so finding parts cheap is not a problem. https://picasaweb.google.com/1040422...2602/Miller55G We can negotiate on that machine. Like the Hobart..it was a project Ive lost interest in and I can use the space. When Larry comes back south later this year, he gets the Hales milling machine and then I should have most of my back yard back again! Yay!! I put my hammock up this afternoon, over my new lawn, so now Ive got a shadey place to enjoy the breeze and read a book (and take a nap) (Grin). I picked up a nice automatic Boyar-Shultz surface grinder (automatic feeds) with a nice 6x12, fine gradation mag chuck, and Im going to be bringing it home as soon as the van is on the road, so my BIG 6x18 surface grinder is going to be up for sale. Folks here will get a heck of a deal on it, if anyone wants it. . Else it goes on Craigslist for reasonable money. Same with the KO Lee B300 tool and cutter grinder. Ive had that lil girl for about 7 yrs now..and have used it so little that I cant see any reason to hang on to it and have it take up space. The Boyar Shultz , even with its hydraulic pump and tank will take less space than the 618 grinder, so with the KO Lee and the big surface grinder gone, Ill have room for a bunch more of those old computer punch card cabinets, which I picked up over the past couple years and have tucked away in storage down in So Cal. Then Ill have good storage for my endmills and cutters and whatnot. Spring is here and its time to revamp the shop and yard again. Back later! Oh..for "LaGrange"....plink. Better hustle up #20 nym or Ill not be reading your dreck. Its not like you have anything else to do...right? Snerk!! Gunner |

No one has called for service. Oh..you are talking about someone who has a 9-5 job? Really? I havent had that kind of work for almost 20 years, when I managed 3 different companies in the prior 25 yrs.

The camera's should already have the IR filter removed because they come with IR LED light source. Why would it need an IR LED light source? You're only looking at it when the transmission is in reverse. (And at least on my Nissan Cube, the screen is only active when in reverse -- in forward or stop it is control of the entertainment system, or the GPS -- or both at once. Granted, I would like to have it come on without having to switch into reverse occasionally. And I guess a third-party one would tend to be on full time -- easier wiring than having to tie into the back-up lights. Now -- the cheap "security system" from Harbor Freight does have LED illumination -- for short distances, at least. One camera is under a solid piece of furniture where the cat hides during thunderstorms, and it is pretty dark there without the IR LEDs. But remember that the inverse square law says that there will be very little illumination as the distance increases. But it does a nice job of showing close snow during a storm at night. :-) On topic, machining required for camera mount to scope and monitor mount.

It was fun to use for science experiments with our 3-5 imagers, to compare it's transparency in IR to it's opacity in visible. We didn't have any silicon wafers handy, but had plenty of prototype far IR imagers to play with. Nice the patterns body contact makes as the body heat is conducted through typical clothing. :-) [ ... ] I looked up some FLIR info a while back and saw the major expense was the lenses. There were various FLIR systems -- some were prototype, some actual production items being sent into the field. FLIR stood for "Far Looking Infra Red", and applied to both the far IR which we have been discussing, and also near IR (just below the frequency (above the wavelength of visible light.) Those near IR systems had big Catadioptric (sp?) (mirror) lenses, and a multi-stage image Intensifier. You could also use standrd visible light lenses with the near IR systems. The night vision scope on the rifles, and later ones with single-stage microchannel intensifiers, used plain visible light optics. I'm guessing the sensor array wouldn't work well with just a pinhole for a lens? How long do you have to integrate each pixel? A pinhole means very little thermal difference, so you have to average the signal for a long time to see a difference. (Lots of thermal noise from the sensors with that little illumination.) I saw Digi-Key had some sensors but they were low resolution, 8X8 IIRC. It still would be fun to play with, perhaps interpolating between pixels for sub pixel resolution, at least to get an image bigger than 8X8 on a screen. It probably wouldn't be very good but at least maybe you could locate some thermal variation. You could use pure mirror lenses, with just a spider supporting the front mirror, not any transparent support, so the lens should work as well for far IR as for visible light. And the trick with sensors like that is to scan them to get more coverage. One trick was a rotating multi-faceted mirror, with each facet at a slightly different angle relative to the axis, so it scans a line parallel to the previous one. Of course, this requires a fairly quickly-responding sensor, so likely would need cryogenic cooling to keep the thermal noise down.

[ ... ] I know for IR reflectors I have seen, they are a gold color. Would those mirrors work for far IR? Sure. For far IR, it doesn't take much to reflect it. A plain sheet of aluminum looks like a mirror to an IR imager. If you want to use glass as the basis, you need first-surface coatings for the reflection. (That is -- unlike normal home mirrors, the light does not pass through the glass to the metal coating, and then pass through it again. Most glass is pretty opaque to Far IR -- with the exception of specialty things like IRTRAN. I have a BOE BOT educational basic stamp robot that has a servo and a "Ping" ultrasonic sensor. The servo sweeps the sensor back and forth, pinging distances to objects at various angles and turns the robot in an open direction. There is a program for the programming computer to read this data and it gives you a graphical representation of what is being detected. I thought about trying that same approach with a single IR temperature sensor but plot a direction and a color representing temperature. Yes -- but you are missing something that the ping gives you -- distance. Since you are seeing the IR radiated by the object, not something reflected off it from a short pulse from the sensor end, you really don't have distance information. If this were fast enough a person could use mirrors like a laser printer uses (old ones anyway) and get a 2D array with each sweep, like a TV scan but with a temperature sensor. Of course this would be limited by the reaction speed of the sensor. Anyway, with moresensors it could be done better. I guess you would have to have curvature in the mirror and focus similar to a lens? Yes -- a mirror lens, with a second smaller mirror held in the center of the field of view to reflect it through a hole in the center of the mirror. There are such lenses sold for good SLR cameras, and as really high quality telescopes which can be used for limited astronomical work -- if you live in a place without a lot of light pollution. One of the really nice ones was the Questar. I have thought of the above more as a security system to detect people or animals without emitting IR light that someone can see with night vision. It will tell you the direction -- but not the distance. If there is only one hot spot, a second system could show you a different angle and where they cross is your target. I watch some videos of thermal vision hunting and it really highlights the animals over the background. I suspect that a polar bear would not be that visible -- they have really good insulation. :-) We have a FLIR camera at work that we inspect electrical cabinets with, shows weak connections that need tightened or replaced before failure, very interesting technology. Including things like aluminum wiring, which tends to degrade its connection with thermal cycling. (A primary example of the needing tightening). One intersting thing with something like that -- take a pad of paper, place your hand on it for a few seconds and lift it off. You will see a handprint which will slowly fade away. And -- if you have someone with a bushy mustache, have him breathe through it, and it will light up as his exhaled breath warms it, and darken as he inhales, cooling it. (Or the opposite, if the system is switched to hot-dark mode. :-) Enjoy, DoN. -- Remove oil spill source from e-mail Email: | (KV4PH) Voice (all times): (703) 938-4564 (too) near Washington D.C. | http://www.d-and-d.com/dnichols/DoN.html --- Black Holes are where God is dividing by zero --- |

I used to repair to repair copy machines for about 10 years and most of them had first surface mirrors to reflect the document image to the photoconductive drum. When I did controls engineering one of our customers made automotive lamp assemblies and used aluminum vapor deposition to make the reflective inner housings. Very interesting technology but the good stuff is pricey, the other day I saw an ad for a thermal imaging rifle scope for $8,XXX . RogerN |

RogerN I was given an HP6110 Officejet all-in-one that couldn't Home at startup. HP's repair instructions for that problem are to buy a newer model. The lamp causes nearby plastic to outgas and fog the front-surface mirror. I cleaned it well enough for home use with CRC Mass Air Flow Sensor Cleaner and a degreased Q-Tip. Is there a better choice? --jsw |

: I used to use rubbing alcohol and a light touch with cotton pads, the surface seems to scratch easy. The alcohol streaks but if you keep rubbing until it dries it seems to work well. The strongest solvent we used in cleaning copy machines was MEK but never needed it on the mirrors IIRC. Although they're a LOT more expensive than isopropyl alcohol and a cotton ball, 3M puts out a line of singly-pouched little 'nappies' with just the right solvent blend and abrasion-free fiber pad to clean 1st-surface mirrors. Duh... yeah.... pure aluminum with a 1/10 micron coating of silicon dioxide IS, indeed, easy to scratch! Lloyd |
