PiVR: $415 to create a VR platform for small creatures
PiVR stands for Raspberry Pi Virtual Reality system. It’s an open-source design published by David Tadres and Matthieu Louis that allows dynamic closed-loop experiments to study unrestrained optogenetic stimulation of neural functions in small creatures. The device tracks a small creature at 50 Hz, and generates light stimulation patterns based on the position of the […]
AttoBright: A single-molecule confocal system built from a 3D-printed scaffold
The AttoBright is a 10×20 cm single-molecule confocal system capable of single photon counting and fluorescence correlation spectroscopy. The scaffolding is designed to minimize the amount of optical components needed, and make those optical components easy to install with automated alignment. A paper by James Brown, Arnaud Bauer, Mark Polinkovsky, Akshay Bhumkar, DominicHunter, Katharina Gaus, […]
$1200 for a Super Resolution Capable Microscope
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 […]
