This semester I will try to do a single small project on my own. In my little spare time I want to make a data logger to fly up into the atmosphere on a kite. I have already ordered the components that I expect that I’ll need.
- 3.3v 328p bluepill microcontroller – 3.06g with rear male header only
- micro sd card reader – 2.43g
- sd card – .25g
- pressure sensor
- humidity sensor
- a battery
- a large kite -it’s a giant bird with a huge wingspans for lift, pictures soon
I expect that the entire device will be small, but I am uncertain of the weight total because not all the components have arrived. I also expect that I will do what I can to reduce the weight by grinding away boards where possible. I intend to affix the logger to the kite either by means of duct tape or needle and thread.
I will write the logger program in C++ with vim and then upload them using this vim-arduino plug-in. I will write the data visualization code in R, and make all my code available with some explanation.
In the end I estimate the total project will consume 10 to 30 hours of time. I think a fair amount of that will be split between writing code and actually flying kites. The nature of the wind is that it is chaotic, but I can’t even go out for a windy day until I have all the components assembled and working. I’ve never used one of these 3.3v “pro micro” controllers, though they seems as easy as the Nano clones I like.
Nevertheless, I am getting really good with this stuff and I have no intention on stopping them any time soon.
