hi John i have one as yes they are good but difficult to focus - the slightest movement makes them go blurred.
i have a 200x on a small stand.

excellent for examining tracks , they become about 5mm wide on screen but then what?you can't solder with one. they are purely for examination - not repair.

i use mine very rarely but on the occasion i have, they do work.

I use a similar endoscope to the first one at work wildlife surveying. I have to say that I don't think it would be very helpful for soldering jobs...

Can't comment on the other ones, but the second link looks the best :D

thats okay then , its some hit and run chinese make , same the white 200x in your ebay adverts but my is the more expensive , higher spec black one ...just the same but black really :-). i tried to find a good quality but cheap one and failed. having said that it works although mine has very bright led's near the lens and you get glare from PCBs

i use it on my mac (usb) and i works just fine but in reverse lol.. the software for windows cures this.

image quality is very good and for inspect . excellent really,

mike.

Hey John,

I looked into these a few weeks back when I was troubleshooting the A1200 PCB. I already had the Veho VMS-001 but it would not work with Win7 x64.

Things to look out for in these cheaper USB scopes:

- Is it supported by the OS you intend to use it on?
- Does it have up to date drivers? Some will not work with 64bit OS'es.
- Watch out for the claims of high megapixel count. Some of these sellers are saying 50MP but they're simply comparing the size of the physical object against the magnified image on a large LCD monitor.

I'm on the look out for an affordable stereo zoom microscope with a long reach boom which will be much better for the purpose of soldering and inspection. We used them at HP for soldering the wires which connect hard disk read/write heads. They were high power stuff but you'd probably only need 20x to 30x magnification for fine hand soldering. The stereo helps to give a 3D view and feel of what you're doing.

I think a lot of people use a loupe but I can't as I wear specs. :blink::lol:

In the meantime I'm tinkering with making an adaptor for the sensor of my VMS-001 to fit onto a Nikon Macro lens. Not sure it'll work yet.

If you have a digital camera with live view and live connection to an LCD monitor you might get away with using that if you can support it with a tripod or arm maybe. You'll also need some good all round lighting.

All the best :thumbsup:

The drivers for these camera's are pretty simple and any windows version should support them from XP and up. The extra toys on the camera software is pretty rubbish - slide show ,video maker and such - junk to be honest.

my camera has two focus zones and a whole lot of dead zones - i.e no focus (you would expect this of course). the first focus area is something like 20x zoom and is pretty good for PCB inspection, the next soon is 200x and then its hard work as the area on camera is so large that the slightest moment of the camera sends the picture miles away from the area you want to look at. Patience is the key here.

yes they work and yes they are useful but within limits..

i'll do a review of mine if you like John.

thanks guys i got a very basic one for now see how it goes if i need a better one my kids can have it

mike a review would be nice

ed them stereo ones look great but a bit too much for basic stuff if you do decide to make an adapter post the piccys :thumbsup:
