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–…
Introducing the Spectrino
Posted in Hardware
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…
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…
Arduino – a simple microcontroller
Posted in Hardware
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…
