As part of TENSS we have created a set of examples showing how to use DAQmx in MATLAB without the Data Acquisition Toolbox. This…
OpenMV – Fast and easy machine vision
OpenMV is an open source machine vision system. It’s designed to be easy-to-use, with a gentle learning curve. They want this to be the “Arduino of Machine Vision”. The software IDE…
Moire lenses
Posted in Hardware
Moiré lenses are cool: two patterned diffractive optical elements are rotated relative to each other to vary the power of the “lens”. Just watch the video (below).
Demonstration of focus-tunable diffractive Moiré-lenses

PMT power supply
I was cleaning house a bit, and among my old files I found this, which might be worth sharing. Years ago I made a centralized power supply for a custom 2-photon imaging system I built. There…
Driving a green laser pointer with MicroManager
Posted in Hardware
Reminder: green laser pointers have a ton of IR in them. It needs to be filtered out if you don’t want it. See this old (2011!) Labrigger post.
Pixy computer vision for tracking mouse behavior
Pixy is an open source computer vision system. Mostafa Nashaat, Robert Sachdev, and colleagues including Matthew Larkum have developed software for use with the Pixy, that can be used to track mouse behavior, including free movement…
Analysis algorithms: performance quantification and ground truth
Posted in Software
We recently tweeted about a preprint from Eftychios A Pnevmatikakis and Andrea Giovannucci (code). The preprint is on motion correction for calcium imaging data. It is a nice quick read and discusses earlier work…
