Appreciation post: My $250 digital microscope saved a repair I almost gave up on

I had a Minolta X-700 on the bench with a shutter that just would not fire right. I was ready to call it a parts camera after two days of poking around. On a whim, I ordered a cheap digital microscope from an online store. It showed up three days later, and I hooked it up to my laptop. The first time I looked at the shutter curtain gears under 200x zoom, I saw a tiny, broken tooth I had missed completely with my loupe. It was so small, but it was enough to jam the sequence. I made a new tooth from a bit of brass shim stock in about an hour. The camera works perfectly now. Has anyone else found a specific tool that turned a lost cause into a win?

That "tiny, broken tooth" is exactly why I got one. My old magnifying lamp just couldn't cut it for surface mount soldering. Seeing the actual solder joint shape on a screen changed everything for me.

Karenb97 is right about it being a nightmare. I used to do the same thing and it's wild how much better the digital scope is for seeing bridges.

Wait, you were actually soldering surface mount stuff with just a magnifying lamp? @wyatt135, that sounds like a nightmare. I tried fixing a tiny resistor once with my old desk lamp and it was impossible. I couldn't even tell if the solder was a ball or a bridge. Getting a digital microscope felt like cheating because you finally see the real shape of everything.
