Using a cheap USB microscope for paste stencil alignment

A minor thing, but a big time/back ache saver when you can't get right over the stencil to crank the alignment micrometer adjustments just so:

the "with virtual glasses" model.

It's kinda weird having your head pointed in a completely different direction from what you are "looking at" *and* having the image stay in your field of vision regardless of how you move your head!

Helpful when soldering, also, as you can turn your head to get away from the fumes and still have your eyes focused on your work. Beats being glued to a stereoscope or mantis.

That's a different price range for sure (maybe 100x more), but comparable to a good stereo microscope.

I take it there is no perceptible lag in the glasses? I experimented with using cameras on stands about 10-15 years ago using cameras with video output, but the lag made it useless for doing anything but inspection.

There's a spare HDMI input on the 50"-ish screen I'm typing this on now, I wonder what it would cost for a 4K video camera on a stand with an illuminator.

The other issue with inspection is depth of field, it's hard to tilt the item to get a look at the sides of things where subtle issues sometimes hide.

I 3D printed a fume extractor using a PC fan salvaged from a dead power supply and some Aliexpress carbon filter material. No more fumes curling up towards your face. It doesn't take much air flow. Pretty quiet when you run a 12V fan from 9VDC too.

Hi Sphero, i'm curious too, so I looked a quick search on Amazon

$190.90

I've not purchased one yet, but once I get back in the lab maybe... it is very enticing. Even if there are QC problems, at least returning it via Amazon is an option.

Please let us know if you jump on this

I thought, with the covid lockups, you were mocking my waistline.
