Ennio Morricone who created unforgetable music is no more

Ennio Morricone's music was magical and lilting.

His music was arresting and spell bounding. It was the most perfect background music for a western. Sorry, spaghetti western. 

May his soul rest in peace.

Great news from Cambodia

Cambodia's Siem Reap province issued an order banning the buying, selling, and butchering of dogs for food. This is a great step towards stopping animal cruelty. I do hope they extend it to the whole of Cambodia.

GPIB for instrument control

It is an IEEE-488 specification related to short-range communication.
It is an 8-bit parallel multi-master interface bus specification known as "General Purpose Interface Bus (GPIB)".

Why do you need it?

You need to carry out automation of Industrial and Scientific Automation. GPIB-RS232 can be used to control instruments using a computer via serial-bus. There is also a USB/GPIB interface that can be used with USB ports. The computer is the 'talker' and the listener is a 'Control' and they talk using a computer program.

What are its requirements?

It needs both hardware and software. More on these here: http://na.support.keysight.com/pna/help/latest/Programming/Learning_about_GPIB/GP-IB_Fundamentals.htm

I personally used the National Instruments GPIB board (Old version) with LabView software.

We were building a Free Electron Laser at Princeton University for which I had designed a magnet. The important information is to measure the magnet's magnetic field in a physical region in and around the magnetic gap through which electrons will be traversing to a high resolution.

The field and the  'fringe field' are crucial to understanding the electron trajectory and it must be measured.

This measurement using a Hall Probe must be made very precisely and cover a large area with high resolution. Automation of measurement is the only way it can be done using three-dimensional motion controllers. This was accomplished with the GPIB software interfaced with LabView.
