USB Microscope

[gtv2000]

I noticed a record I knew pretty well sounded off, so I looked at the stylus. To my (60 year old with bifocals) eyes it looked okay, but I decided to get out my USB microscope.


Before



Sounds better after


And here's the one I put on while I was examining the other


And after



The microscope is pretty handy..

Is that as close of focus it will provide?

Pretty much. You're not going to check wear of a stylus with this.

 

[MRL_Audio]

Knew that. Use a Shure scope for that. Just wondering how far in you can go with what you offered up here.

Could you show us your setup? How do you hold the cartridge?

This is my DL-103 tip.

That's a good looking stone.

Sorry, I already put it away. This scope comes on a stand. I have the cartridge in a headshell and it just sits on its side. Then you can adjust the zoom and position of the scope head with screws. It's pretty convenient. If the cartridge isn't in a headshell you could most likely just lay it on it's side.

This one also has a built in lamp which makes it easy to illuminate the object.

Thanks for the details.

This is about as close as I can get in with my USB unit:









Like TnSilver said, the focus backlash/lack of precision is the killer on the cheap ones- mine was about $50.

My real microscopes are way,way better, but they don't have a digital camera head and it's no fun to try to manipulate a camera over the eyepiece.

What USB microscopes are you guys using out of curiousity ($11?)

 

[tnsilver]

search "Digital USB Zoom Microscope" on the auction site. The one I got for $11 a couple y/a, now costs about $17.

John, How many mega-pixels and max magnification on your USB unit?
Thanks
