I need someone to explain this to me.

USB microscope used for soldering very small things

Lasik eye surgery is pretty common these days, but there are of course easier and cheaper ways to solder SMD components. [techpawpanda] wanted a video camera to see what was going on when he placed and soldered very tiny components on his board, but commercial SMD video cameras were terribly expensive. He wound up using a USB microscope to place and solder these tiny parts, and we’re thinking his SMD soldering station is the bee’s knees.

[techpawpanda]‘s video-based SMD station is built around a USB microscope available at the usual online retailers for $40. This camera is mounted on a wooden base with a USB hub allowing the camera to be plugged in along with a few USB LED lights and a USB fan for a rudimentary form of fume extraction.

The results are impressive – even at 11x magnification, [techpawpanda] can put paste on pads and place even the smallest SMD parts. All this in a device that is small enough to fit in a shoe box, or be tucked neatly away whenever it is not needed.

Microscope reactive digital aquarium


[Amos] sent in the Living Interface. I call it a microscope reactive aquarium. A small light sensitive animal is inside a mini-aquarium on the scope plate. The wires are attached to lights at the edges to attract the animal. The position of the critter is reported via a digital aquarium. (looks like an empty aquarium combined with a projector. Aside from looking friggin cool, it has applications for measuring water toxicity by measuring the reaction time of the animal.

A while back, a friend of a friend supposedly used a USB microscopes to measure yeast activity in his beer brewing. If anyone runs across it, let me know.
