Hackaday Prize Entry: An Internet Of Things Microscope

Posted on by

For their entry into the Citizen Scientist portion of the Hackaday Prize, the folks at Arch Reactor, the St. Louis hackerspace, are building a microscope. Not just any microscope – this one is low-cost, digital, and has a surprisingly high magnification and pretty good optics. It’s the Internet of Things Microscope, and like all good apparatus for Citizen Scientist, it’s a remarkable tool for classrooms and developing countries.

When you think of ‘classroom microscope’, you’re probably thinking about a pile of old optics sitting in the back of a storage closet. These microscopes are purely optical, without the ability to …read more

Automating A Microscope For CNC Micrographs

Posted on by

[Maurice] is a photographer specializing in micrographs. These very large images of very small things are beautiful, but late last year he’s been limited by his equipment. He needed a new microscope, one designed for photography, that had a scanning stage, and ideally one that was cheap. He ended up choosing a microscope from the 80s. Did it meet all his qualifications? No, but it was good enough, and like all good tools, capable of being modified to make a better tool.

This was a Nikon microscope, and [Maurice] shoots a Canon. This, of course, meant the camera mount was …read more

Hackaday Prize Entry: Microscopy With Blu-ray

Posted on by

Confocal microscopy is an imaging technique that provides higher resolution micrographs than that of traditional optical microscopy. Confocal microscopes attain this higher resolution from an image sensor behind a pinhole. By eliminating out of focus light, and by scanning the specimen back and forth under the microscope, a very high resolution image may be produced. This technique has applications ranging from life sciences to semiconductor work. For this year’s Hackaday Prize, [andreas.betz] is building a confocal microscope using little more than a Blu-ray drive read head.

[andreas]’ build uses a standard Playstation 3 Blu-ray drive mechanism. The read head for …read more

One Hacker’s Small Tabletop Photo Studio

We love good pictures. You know, being worth a thousand words and all. So, after our article on taking good reference photos, we were pleased to see a reader, [Steve], sharing his photography set-up.

Taking good technical photos is a whole separate art from other fields of photography like portraiture.  For example, [Steve] mentions that he uses “bullseye” composition, or, putting the thing right in the middle. The standard philosophy on this method is that it’s bad and you are bad. For technical photos, it’s perfect.

[Steve] also has some unique toys in his arsenal. Like a toy macro lens …read more
