Looking for a camera slip-on widget...

Anyone ever see something like this avail off-the-shelf?



We have a spectrum analyzer that (on occasion), it would be nice to take a movie of the screen, to share with other engineers. This is a field unit, not something you'd find in a lab or bench-tech environment.



The screen measures about 4"H x 5.25"W, color. Not sure of the scan rate. I could find out.



Is there a "box" or something I could slip over this thing, with a camera inside that could take a movie of the screen and ideally, dump it off to an SD card? The "box" would prevent stray light from entering, and would guarantee a consistently sharp focus.



This might be a one-off build (DIY Project), but I just wonder if the wheel's already been invented.



Thanks, mpm


I use my phone, with a light shield made out of a convenient-sized cardboard box with a hole in the bottom. Works great.

Get a plastic flower pot of the correct size and paint the inside black. Or not. Cot a hole in the bottom for the camera lens and just hold it to the scope.

Old Polariod scope cameras go for peanuts these days, might be possible to modify one of those (with bellows etc).

Personally, I just lower the room lighting* and take a photo with a little point and shoot camera (it can do video 1080p if I want). One of those little gorilla tripods is handy (knockoffs are almost free, and the real ones are not expensive).

*Not so handy I guess if you are in a cubicled office with one light siwtch and _not_ working late.

This is something you design/manufacture? Or, something you

*purchased*? I.e., do you have knowledge/access to its internals?

You really want "moving pictures" and not "still photos"?

Absolutely!! And, many point-&-shoots and cellphone have an autofocus that might get fooled by a changing spectrum trace. And yes, to the other poster, I want movies. The instrument takes screen captures just fine by itself. Also, in some situations, we'll have little control over ambient light.

And -- whoever designed this spectrum analyzer must have a brother-in- law who specializes in glare glass !!!! It's truly awful.

I'm OK with rolling my own, I just didn't want to experiment. Time is pretty valuable at the moment....

One of my favorite companies too! They make a really nice fine-tune focus mount for macro photography work.

You can even get square black plastic pots. And mobile phone or P&S these days will have a video mode but not all will video at close quarters in macro mode so you might need to chose the camera well.

I'm getting rid of two scope cameras (spoken for by collectors). Scope cameras are really heavy. I think they would be a bit unwieldy unless they fit the target device. I see a few on ebay for outrageous buy it now prices.
