This past week Ervin and I began setting up the motor and running it with the ESC and RC controller. We connected the battery to the ESC and the ESC to the motor. The receiver for the RC controller also connected to the ESC. We could not get the motor to spin for days and believed this to be a problem with the receiver. Ervin managed to figure out why the receiver was not working while I was away.
I met with Professor Bruno and we talked extensively about the physics behind drag forces and what to expect when calculating the humanitarian drop. He gave me a list of 1950s fluid dynamics videos to watch and I started watching those already. Also in terms of how ground speed was measured during World War II the best I could come up with was measuring the distance between known objects on the ground. I also found that radio was used to find ground speed. Done by measuring propagation delays and measured in nautical miles.
I began to test the chipKit Max32 board this past week. I had it blink an LED on and off to make sure that it was working. I have been trying to connect the Eagle Tree altimeter to the microcontroller, however, I have to set the altimeter up for third party use first. To do this I am using the Eagle Tree eLogger to enable third party use.
Although once I started exploring the Eagle Tree sensors and data logger I discovered that they already had a lot of the work figured out for me. I used the data logger and the GPS sensor to try and get a GPS fix on my location. But even when I was outside I could not get the GPS to get a fix on my location in live mode.
My goals for this next week are to see what sensors I can use from the Eagle Tree kit and if I can use my microcontroller with those sensors. Or if I want to just use the sensor kit and get rid of the microcontroller idea altogether. By this time next week I would like to at least have altitude and air speed readings.
