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 were two epi…



Controlling a bunch of servos

A friend just asked a quick question: How can I make a bunch of cheap (not fast) laser shutters? Here’s a quick answer: For motors, servos are pretty easy to use. Put a piece of black material…



Processing 2

One of the first posts in this blog was on Processing. Processing is a programming language with an integrated development environment that is specialized for simplicity– ease of learning and coding– and intended…



Introducing the Spectrino

The Open Hardware wave keeps rolling: MySpectral recently announced the Spectrino – an Arduino based spectrometer. It’s as barebones as spectrometers go, with the small enclosure containing a diffraction grating, CCD light sensor and an…



Streamlined & simple prototyping to custom PCB

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…



Arduino – a simple microcontroller

Arduino is a popular, cheap (around 25 USD), and open source microcontroller platform. We use them all over the lab. Students can learn to program them very quickly, they’re versatile, and there is a large…



Processing

Processing is a programming language geared towards visual artists, but it comes in handy for a lot of other purposes as well. Here are some of its finer points:

Open source
Integrated IDE (see below)
Lots of demos…
