Don’t leave me…

Since the last post we have completed a year of successfully RF measurement campaigns. Sadly, the quadcopter seen in the last post (FEMU 1.0) underwent a autopilot failure  during a measurement dry-run which caused it to fly straight up into the air until its battery died. It has never been seen since… This forced us to build FEMU 1.5 in 3 days. being a temporary vehicle, FEMU 1.5 was decommissioned shortly after his first measurement campaign (25 flights). All this happened in the earlier part of the year and gave us the opportunity to do a complete redesign which will be discussed in the next post. This redesign formed a large part of my PhD degree and made attempts to break new ground in RF metrology using Multicopters.

This was also the start of our quest to 3D print antennas, see the 900 MHz antenna mounted at the bottom.

Python in Eclipse

A short brief walk-through on setting up a python environment in Eclipse with the necessary libraries. Note that all installers need to be of the same architecture namely 32bit or 64bit. This walktrhough will focus on the 64bit case.

1. Install the latest java runtime environment

2. Install the latest python distribution

3. Install the latest eclipse environment

4. Follow the instructions on the pydev site to install and setup the pydev module

5. Install the fundamental libraries from this site, below is a list of packages I would recommend:

  1. SciPy
  2. Numpy
  3. Matplotlib

I would recommend looking for the latest versions of the linked applications.
