JD:
Need to see certain machining processes behind the work piece, take a look at this neat bit of kit.

http://www.maplin.co.uk/usb-digital-microscope-with-400x-magnification-286566

Plug and play, comes with a CD of software and at £39.99 not a bad price.
You could use this beastie to get up close and personal on a whole range of processes in the workshop, mine is on order.

Bluechip:
I have one similar or the same design. Not from Maplin though.

I think you won't find it all that useful.

400x magnification is just a joke. Divide by 50 and you're in the useable range.

It appears to have the same push-button as mine ... so, when you click ... the image buggers off into the next county.   :Doh:

It is possible to download drivers to get it to ekkle on Vista 64 & W7 64. I think.

Or, at least mine does ... on W7-64

Other than that, they are fun ...  :)

I'm glad I didnt spend my hard earned on one then... :Doh:

andyf:
Is the "400x magnification" by length or by area? By length, a square with sides of 1mm would look like one with 400mm sides, but by area the sides would only look like 20mm.

Bluechip:
Andy, I would think it's by area. Can't imagine it doing anything else.

John, depends what you want to do with it. Imagine a 8X hand lens that takes pics.  :thumbup:

If that's what you want, you're in business.

OK so 400X magnification. Object is 1mm x 1mm. It only reflects/transmits so many photons !!

Magnify by 400, it's now 20mm x 20mm, same number of photons spread about.

You can do a lot with a CCD or whatever, software integration of the image etc. but you can't hold the damn thing still enough..

But they can be useful ... just not quite as wonderful as the blurb implies.

IIRC mine had the same wild claim, but having had an optical uScope I know anything like those numbers is not likely. I had an Olympus summat or other. 10X eyepieces and a max of 100X objective. 1000X ??
Not a chance .. not to see anything useful anyway. That was a good uScope. I would imagine similar performance model £3K + now, and that one was only good for 200-300X tops and that was pushing it.
Too good for the likes of me anyway ..  :(
