Science

I was telling Nathan how flex circuits like are used in LCD screens for desktops of a few years ago
are a commodity process of making layers with 50 micron width and space between and might be
repurposed to fabbing microfluidics inexpensively. I took a flatbed scanner photo of the flex circuit
that could not get down to its resolution, and emailed that, and
offered to send him a piece to look at under a microscope,
since I did not have any good digital camera for microscope photos.

I was saying how I'd take the lens off of a Canon powershot for that, but it still has a crummy user interface
for microphotography, which triggered him telling me about this:


https://www.kickstarter.com/projects/botthoughts/openmv-cam-embedded-machine-vision

It's got a perfect user interface for microphotography -- python programmed machine vision
programs that can recognize features in a scene. Just add a little problem-specific
development and you have a cell counter program. Well, add that not-yet-existing, accurate and inexpensive
plastic molded microgrid to drop on your samples then top with a cover slip, *then*
hit the go button of the counting program...

A hood is not necessary, I was 14 or 15 when I achieved sterile technique in my mother's kitchen over an open oven. 10+ years later the most I've done as far as  sterility is to make a still-air box, and to know when to be careful.
