For circuit board repair and watch repair but also general stuff that's getting harder to see these days.

Under £200 with ability to record and output to a TV and computer.

Many thanks in advance.

Found this one online but not sure if there are betters hence asking the PH massive.

Long time since I bought anything in this line.

The big issues tend to be depth of field and rigidity.
I bought a cheapo USB microscope ages back, which worked fine when I'd mounted it to a steel frame!

We had a 'boom microscope' in the lab. A normal microscope intended for slides can't access big things like circuit boards.
I'd consider one of those with camera that replaces an eyepiece.

Another approach is to use a standard digital camera which has a lens which does 'macro'. You can get various 'copying stands' or invent something.
You just need a camera with a live video out.. Annoyingly I have a mega-zoom camera which doesn't do this.

Depending on what exactly you're doing, you should consider what magnification you really need and also the lens-work distance, you need space to get in there with e.g, soldering irons and don't want to spatter the lens with flux or worse.


Quick shufty at ebay suggests a tri-ocular boom microscope and a USB eyepeice camera is only about 50% over your budget....


This might be of interest to people in the DIY sub-forum? Please let us know anything you find out.

In some of the schools I work in the teachers use USB Visualisers.

They have built in lights and a good zoom function. Connect them to a PC and record everything, or display it on a large screen.
They're not too expensive either. Amazon has them starting around £40 all the way up to £400.

Friend of mine has one of those and likes it. These are his photos - of the screen and the resultant picture (note these are what I downloaded from FB Messenger, so much reduced size/res)


I've added one to my basket on the hope of a really good black Friday type deal. Have seen it drop to £144 occasionally.

An Amscope stereozoom microscope is the most sensible option for board repair. If you want to output the image to a screen then you'll need the trinocular output. I'd also get a 0.5X auxiliary (Barlow) lens to double the working distance between the bottom of the microscope and the board. It also stops solder fumes getting into the optics.

Thanks all - very useful.

I'm still swithering as it appears to have a few things that make me think spending a bit more might be wiser. In particular I'm not sure if the zoom is based largely on how close the camera is to the subject. If this is the case then obviously it would make zooming in close up much harder to get tools etc access to the subject for watchmaking and board repair.

It also seems that files are only stored on jpeg rather than raw/tiff and that the camera is using interpolation from 4MP to 16MP for the quality.

I found this review that makes me think extra money for something else might be the smarter move.

I just can't get on with digital microscopes, the lack of stereo optics means that you don't get the depth perception.

With an optical microscope, zooming in doesn't significantly change the working height.

A bit more than I was hoping to spend initially!

Have bumped a watch tools thread on the Watches section rather than Computers, Gadgets & Stuff in the hope for ideas.

Many thanks.
