NMRduino – Open Source Imaging
Many students, researchers and hobbyists will be familiar with the open-source-electronics ecosystem “Arduino”, which provides an extraordinarily simple way to interface sensors (or other input devices) and actuators (output) with logic programs, e.g. C code, to create a wide variety of standalone control devices termed embedded systems. An NMR spectrometer can be regarded as one specific type of embedded system: the output is a magnetic field produced by a coil, the input is a magnetic field (detected and recorded by a digitizer), and a pulse programmer keeps timing and data in order.
The “NMRduino” is a magnetic resonance spectrometer based on (but we must stress, not endorsed or supported by) Arduino that we have developed over recent years to study hyperpolarized NMR systems, NMR relaxation, high-resolution spectroscopy, and coherent control at low magnetic fields, as well as teach basic principles of magnetic resonance to student beginners
