Title: Video microscope!
Post by: iXod on March 15, 2013, 07:45:43 pm
Great review(s) re. your ultimate microscope, the Mantis. Pure envy!

But for those of us without $3K-plus in our budget -- I've always thought how nice it would be to make my own video microscope: a small close-up (variable focal-length?) video camera and a small display (6" minimum) with a port for larger monitors.

How about your next project, Dave?

Cheers.

These things are quite handy: https://www.google.com/search?q=usb+microscope&tbm=isch (https://www.google.com/search?q=usb+microscope&tbm=isch)
Of course, as with everything, there is the good, the bad and the ugly. I have one that costed me like $50 and it is ok for the occasional need to have a good enlarged look at something.

Problem with most of these is focal distance is small. Need working distance enough to solder and see something that might be taller than a PCB.

Also ideal is a 5 or 6 inch LCD display mounted right below so I can look down, rather than larger monitor so you don't have to be looking elsewhere than down (makes for weird hand coordination and neck problems).

Useful tip their Fran... good for those individuals who are on a low monetary budget, and wish to experiment.

Unfortunately my age now and eyesight is problematic,  ::) unable to see SMD or even want too now days;
so sticking with through-hole electronics for my projects while stocks last, and where available; so as the
interest takes me, to spend time at the bench.

Although after any useful experiment, with a wanted or good outcome,  :-+ I spend far more time drawing out the circuit,
drafting the enclosure details to a manufacturing level; it's a hard habit to break,  :-\ after so many years in R&D.

Fran,
Nice "home tech".

What video camera are you using to take those vids?

Thanks.

That is a great idea, never thought to combine a couple low cost loupes to get a working microscope. Lots of potential for use with other projects! Thanks for the insight Fran.
