Fritzing is PCB design software (EDA) in the spirit of Arduino and Processing. It’s open source, cross-platform, streamlined, and simple to use. It doesn’t do simulations, but you can lay out your circuit in a GUI that looks like a prototyping board, then move to…
Let me add some clarification to the hybrid PMT post.
The actual signal that comes off of a PMT in response to a photon is a pulse of current. The…
Hybrid PMTs have made their way into fluorescence microscopy and are competing with GaAsP PMTs. (Well, actually, Hamamatsu makes both types, so it’s not really competition…
I’ve used Wescor Vapro osmometers for a long time. Specifically, the model pictured above. They’re nice machines. But now I think freezing point osmometers are better. In this post I’ll talk about why.
The…
The killjoy afficiando commenters at Hack a Day love to deride as unsophisticated any project that uses an Ardunio (e.g. this thread). The platform has become so popular that, to co-opt…
More cleverness from Taro Ishikawa. Instead of buying a homeothermic heating pad for surgeries (these often cost > $1000), Taro used some basic industrial process control items. He bought his stuff in Japan, but similar items are available from McMaster-Carr in…
I was in Tokyo recently and stopped by my friend Taro Ishikawa’s lab (of TaroTools fame). He and Misa are doing very well. They have exciting work underway and are expanding their…
Here are some ideas for project enclosures. The stock enclosures from Mouser, Digikey, and others are generally serviceable, but are rarely the perfect size. In addition, making the required cutouts can be inconvenient. Here are a couple of alternatives.

In the early days of patch clamp electrophysiology, everyone made their own patch clamp amplifiers because there were none commercially available. I was lucky enough to be educated by scientists of such lineage,…
Over a year ago, we covered the OpenPCR project. Following their successful Kickstarter campaign, which netted twice their funding goal, they’re now actually shipping the devices.
To start, this is a $512 PCR…
OpenMoCo is short for “Open Motion Control”. The community is focussed on building rigs for moving cameras.

This is a long post. If you’re in a rush, then just read these first two paragraphs.
One of the early posts on this blog was about …
So you’re feeling pretty good about the rodent virtual reality system (Hölscher et al. 2005) you have up and running. You’ve got it all… the spherical treadmill with motion tracking feeding back…
A while back Labrigger covered some sources for alternative mechanics. Here’s a new one. MakerBeam is an inexpensive kit of construction rails aka T-slot bars. This would be a…
Let me tell you a little story.
The place is the CONFOCALMICROSCOPY listserv.
The time is 1997.
A query asks how to mount fluorescent beads from Molecular Probes in order to image…
