A new paper shows the practicality of using Super Resolution Radial Fluctuation (SSRF) on an OpenFlexure Microscope. SSRF microscopy is a form of Super Resolution microscopy that relies on a post-processing method to generate a radiality map for each frame. This map is used to look for temporal correlations across frames to create an image […]

Make Your Own Portable Laminar Flow Hood
You can make your own portable laminar flow hood from a Vacuum Cleaner, some plexiglass, and a HEPA Filter. A thorough article on instructables walks you through the process. The authors paid $200 in parts for their laminar flow hood, including the vacuum cleaner. If you are worried about achieving actual laminar air flow, you […]
An Extremely Cheap Venturi Vacuum Pump
A Venturi vacuum pump works by flowing water through a tube that has a narrow point where a second tube is connected. The faster speed of water through the narrow point pulls a vacuum in the connected tube. There is a nice little instructable on how to put one together using an eppendorf tube, 3 […]
Easy Expansion of Field of View in Two-Photon Set Up
Two-photon micrsocopy is useful for reducing photo-damage and seeing deep into tissue samples. First patented in 1990 by Winfried Denk and James Strickler, it’s a technique that has been used for decades in neuroscience as a minimally invasive way to image neurons in real time. But we’ve already covered how to make one of those […]
Backyard Radio Astronomy
Want to build yourself a radio telescope? The Society of Amateur Radio Astronomers has a rich catalog of tutorials to build them on the cheap. Of particular interest are instructions to create an “Itty Bitty Radio Telescope” out of a TV Satellite dish, as well as VLF radio reciever kits for $120. And since we […]
