Classic SLR camera flashlight hack

Classic SLR camera flashlight hack
Note: as I like to enter the flashlight contest, I post the instructable now.  There were some major problems, which I will fix the coming week...

Broken or totally obsolete SLR cameras can still look very cool and professional, and have a great feel to it.
To get knowledge of the build, and see which parts are in it, spend time to take one apart.

Total disassembly involves tearing off the rubber grips of the body and glued sheet aluminum inside, taking off the knobs etc. to get to screws, so the chance putting it back looking nicely is slim.

Here we are interested in an impressive appearance, not optical quality.

Needed:

Old or broken SLR (I got a broken Practica B 200, made in the DDR, for E 3.50 in the 2nd hand store). It is fitted with a 50 mm F 1.8 standard lens, in great shape. The camera weighs a whopping 750 g and came with half of its leather case.

One or two 9 (or so) cheap LED flashlights.

Some scrap wire.

As the picture comment says, I bricked the camera by closing it while the unlocking mechanism was removed. Don't want to ruin it with a grinding wheel, sledge hammer or chainsaw, but just got another camera from the 2nd hand store. When it is done, I'll rewrite the instructable...

Step 1Clearing out space inside the camera

Put the lens away for now.  The LED will be fitted in back, so the elements to be removed are the shutter and the mirror.

There are tiny screws here and there, but trying to take the (very thin aluminum sheet metal)  top of will result in knicking and bending, ruining the appearance of the camera. The bottom is sturdier, but only reveals a small space, packed with small steel parts.

So: destructive it will be!! Shutters of SLRs are usually made of cloth, but this one is made of tempered sheet metal pieces! So not only the camera is abused, but my scissors as well!  The mirror seems very difficult to remove, so it is left in place, propped up by a rectangular tube made of shiny sheet metal.

The battery compartment and on/off switch might be placed inside the camera, but this would involve a huge amount of dremeling (the film compartment is just a tad too small for the battery holder). It also would require lots of work on top of the camera, to install a nice looking switch.

Instead, the flashlight housing, with the battery holder and switch already in place, is the external power source. It can be tucked under the camera or kept separately in a (breast) pocket.

I have a Praktica sat right next to me! You have a typo, It should be GDR not DDR. :)

"GDR" = German Democratic Republic
merely the English version of DDR.

Batteries could fit in the former film compartment(probably) but how is the
light fitted?

I think one or two more pictures may be needed. :-(

I have not seen a Praktica since the 1960s. Made in East Germany wasn't it?
