Autocorrelators can be used to measure the pulse width of ultrafast lasers. This can be useful for troubleshooting dispersion in your 2-photon imaging system and generally troubleshooting laser issues. They are big ticket items and often…
Open Electronics has a nice overview and comparison of Linux Development boards like the Raspberry Pi.

Carnegie Mellon is a magical place for robotics, and their CMUcam, an open source hardware project for machine vision, has recently culminated in Pixy. This is a wildly funded Kickstarter project (funded…
You just pay the impact factor right now for a subscription to Nature.
Converting them all into USD for comparison:
US: $38 (19% of the usual price)
Europe: $51 (18% of the usual price)
UK and…
4D Systems sells screens and touchscreens for Arduino, Raspberry Pi, and other systems. Importantly, the code is portable (mentioned in the video above), they have good support, and the hardware plugs right into the boards. It doesn’t get much easier than this. They have resellers…
This isn’t an advertisement. I wasn’t asked to post this. I just want to let you all know in case it’s useful. Newport is having a sale on optics and many of the discounts…
This is perhaps the most exhilarating patent I’ve ever read:

Here’s a excerpt:
When the cookie dough enters the oven, the water in the dough is saturated with sugar and appears to be evenly distributed throughout the dough. As the water temperature…
In a previous post, we discussed how peak power is computed. Although Ti:Sapph laser manufacturers typically quote the average power, peak power is the more relevant quantity for two photon excitation. Here’s a graph…
Here’s an iOS app which is basically a scattering calculator to help plan optogenetics experiments. There are also some plates from a brain atlas.

Mice can learn to navigate virtual reality environments using a spherical treadmill, and this behavior drives place cell and grid cell activity.
Christoph Schmidt-Hieber has started uploading his code to Google….
