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).

Andre and colleagues have a preprint up on their project generating inexpensive instrumentation for imaging and optogenetics experiments. The 100 Euro Lab: A 3-D Printable Open Source Platform For Fluorescence…
I came across Rachel Thomas’ comments on blogging in the context of machine learning, and they’re good. I’ve been telling people things like this for awhile now and Rachel distills them better than I…
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…
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 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…
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…
Multiple people have asked for a discussion of Intan CLAMP patch clamp amplifiers. For those who are unfamiliar with them, they’re miniaturized patch clamp amplifiers. What looks like a headstage, is…
It’s a microcontroller built into a breadboard. Actually, TWO microcontrollers. Both are Arduino-compatible. ATmega16U2 and ATmega328P.
It comes in both black, white, and pink because style matters.
P.S. The bottom side is…
For teaching electrophysiology, there’s still a lack of comprehensive references. In particular, it can be difficult to impart to students an intuitive feel for the quality or fidelity of electrophysiological recordings. How close to the…
Max Planck Florida is running their imaging course again and there’s still time to apply. They’ve got great faculty including Na Ji, Ryohei Yasuda, Yi Zuo, Chris Xu, Jeff Lichtman, Naomi Kamasawa,…
SLAB is trying something new with one project in the lab. Prior to drafting a preprint, we’re blogging the project and sharing the results and analysis. We invite anyone to comment…
The Allen Institute has released the first set of data from their Brain Observatory project. Many of you already know about this, but I wanted to post about it to encourage people to…
