So where can I get a copy made?

[SeaCat]

Okay I have a problem.

I can't find the manuals or schematics for my A/C system online.

There is a circuit diagram on the back wall of the A/C. There is no room to get a camera in to get good pictures of it. Therefore I'll be taking the back wall off the cabinet tomorrow. How can I get a copy made of the Circuit Diagram without removing it from the sheet of metal?

No I can't remove the diagram from the sheet of metal. I tried to already and it started to rip.

Can you take a picture with a digital camera?

Can you take a picture with a digital camera?

Possibly, after I remove the panel.

I'll be doing that of course. How that turns out will be anyones guess though.

Scan it if you have a scanner.

It the back panel won't fit on a scanner or copy machine, then a digital camera is about your only option unless you're willing to invest the time to hand draw a copy.

I would suggest that you rent or borrow the highest resolution SLR camera you can get access to and if necessary get in close enough to image a quarter of the schematic at a time -- merge the images later in your computer. You'll need manual focus and/or macro-focus capability and high resolution of an SLR to ensure a readable image.

The Ususal Clowns didnt catch the part about the camera.

Position two cheap mirrors and get a photo from the mirror that corrects the image it reflects from the 1st mirror.

take the back panel to a place that does photostats. they are used to working from objects laid flat, face up. and to catching every detail.

indeed, any high resolution camera, properly positioned and steadied, [proper lighting etc.] can take a photo of a doc that, when blown up a bit, is still readable.

for instance, my friend's DSLR, a low end Canon of that type, is taking pictures in files of 2 megs or more. it seems to me that would suffice for a somewhat blown up version of your diagram (not sure of its size; assuming it's less than, say 6 x 8; lacking that, weird harold's suggestion of multiple shots would be the way to go.

try finding it on google...

Further to what everyone has said about a digital camera...

1 put it on a tripod and use delayed action to make sure any vibration caused by pressing the release has died away.

2 light it diagonally so that the ink doesn't reflect light into the lens (so no on-camera flash)

3 use manual exposure 'correction' to take 3 versions: as per meter; 2 stops under; 2 stops over. Pick the clearest when you get them on the computer.

4 use the lowest 'film speed' (ISO rating) setting available on the camera, to minimise digital 'noise'

5 Fill the frame (with all or part). Least shake is at close distance and wide angle, but beware of distortion at widest angle settings

6 if the schematic includes colours, choose a light source that keeps them distinct - ordinary incandescent lamps will distort the colours, but you can correct them when you get the image onto a computer, but flourescent tubes usually don't have a continuous spectrum, so some colours get trashed. Sunlight (at an angle) is very good indeed. (if it's just black-n-white these problems are almost non-existent.)

The aim is to get a high contrast, high resolution image - which demands good optics as well as a hi-res sensor - and manual optimisation probably means a high-end camera. For ultimate results, use the raw image, not a compressed format like JPEG (again that means a high-end camera, so you can pick that option).

Hope that helps.

I agree with fifty5.
If your digital camera has a setting for adjustment of "white balance", do several exposures at best settings (or use AUTO).

Use the highest pixels you can.

use a tripod

don't get too close to the image.

do the focus manually.

take slots of pictures.

Good Luck
