Screw shields, simple pleasures
These screw shields make it simple to connect a bunch of stranded wire to an Arduino. This one is available here, or here. It’s a little thing, but it saves a lot…

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…
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 machine…
This is a nicely done (and award-winning) orbital shaker. Orbital shakers can often cost on the order of $1500. This one can be custom built for about $150, with additional units costing about $60 (a single controller and power…
We covered a simple lickometer circuit previously. Another useful interface is a capacitive touch sensor. In contrast to light gate sensors, there are no extra photons floating around that could disturb an…
In academia, we have some nice benefits when it comes to intellectual property. Just about everything we do qualifies as scholarship, and so we take ample advantage of that portion of fair use…
Switching wall outlets remotely, via the parallel port of a computer, a microcontroller (e.g., Arduino), or other simple switches, is desirable in many rigs. For example, timing/triggering lights in a behavioral environment, switching equipment on and off remotely, or coordinating the…
