National Business Technology Conference

National Business Technology Conference 2012 


I went to the National Business Technology Conference 2012 this weekend (Mar. 24-25). I'm going to write about what I thought of it and my experiences. In general though I feel two sided about this. It's a good conference in the sense that it's really an eye opener for people who have not been to business conferences before. It's bad in the sense the speakers are way to general, so they would not be who technology people would be interested in listening into.

Extract from a Book by an ex SR-71 Pilot:
There were a lot of things we couldn't do in an SR-71, but we were the fastest guys on the block and loved reminding our fellow aviators of this fact. People often asked us if, because of this fact, it was fun to fly the jet. Fun would not be the first word I would use to describe flying this plane. Intense, maybe. Even cerebral. But there was one day in our Sled experience when we would have to say that it was pure fun to be the fastest guys out there, at least for a moment.

Python Tutorial to serial programming

Python Tutorial

Edit Jan 29 2013: This site has gained some significant traffic, according to google. If you search "pyserial tutorial" this page is 3rd up. So hence I will edit and make it a bit more understandable, seems like there is actually a need for this!

This tutorial describes the process of connecting to a spectrometer over serial port, and writing a python program to automate collection of data. Normally we would need to enter in the wavelength and acquire the (transmittance/absorbency/concentration) result manually. Since the spectrometer has a serial port, we can write a program that automates this process. In order for python to be able to talk to the spectrometer, we need to get pySerial, which extends Python's capabilities to include interacting with a serial port.

In this python tutorial, I will explain how to:

  1. How to configure Python and pySerial
  2. Verify serial port communication, with a spectrometer device
  3. Write some functioning code in Python and use the spectrometer
