Radio Frequency Visualization

October 28, 2022 Patrick Gilfeather

This post will revisit a topic which has been covered in earlier posts, but with some enhancements. This earlier post used python to visualize a radio sweep, https://www.cloudacm.com/?p=3209. The method was specific to the SDR hardware and the rtl_power command to generate a dataset that was then processed with python to generate a plot. This post will expand on the visualization by using python to generate varied plot types to help in understanding the radio signals observed. The previous post…

Picavet Gravitational Leveling for Aerial Imaging

September 30, 2022 Patrick Gilfeather

There was an earlier post regarding gimbal stabilization, https://www.cloudacm.com/?p=3609. The focus then was using software instead of hardware as a solution. During that research, I found information about self leveling platforms used on kite lines. Here is a video demonstrating the results, but I wasn’t sure how it was accomplished. https://www.youtube.com/watch?v=6Nnqr0onUvk I then found a video from Evan Reinheimer demonstrating his use of a picavet. The picavet is a platform that gravitational self levels when suspended from a kite line….

FLIR ESP32-Cam using the Melexis MLX90640

August 25, 2022 Patrick Gilfeather

This post will cover how to use the Melexis MLX90640 thermal array sensor with the ESP32-Cam module. The work presented here is based off of the work of others and their documented efforts. The reason for using the ESP32-Cam module is because of its low cost, small form factor, and its built in microSD storage. The Melexis MLX90640 thermal array sensor can provide a 32 x 24 pixel thermal image in either a 55 or 110 degree field of view…
