MicroSD Backups with Encryption that Save Space

MicroSD Backups with Encryption that Save Space

This post will cover steps on how to create and secure MicroSD backups, with the focus being on disaster recovery for RPi systems.  This method of backup is hardly the best method available, but it does offer space savings and more security.  In this demonstration, a second Linux system will be used as the backup target with the MicroSD media attached as the backup source. First step is to establish how large the MicroSD media is and if the target…

Visualizing Data with Processing

Visualizing Data with Processing

The purpose of this post is to demonstrate how to use Processing to present data in a visual way. The methods used in this post will be based on the work done by M.Furkan Bahat. Source – https://mfurkanbahat.blogspot.com/2014/11/artificial-horizon-and-compass-using.html The hardware used in this demonstration will be the following: GY-521 MPU6050 Arduino Uno ESP32-Cam ESP32-USB-Module Patch wiring USB cables Windows 10 laptop The MPU6050 is connected to the Arduino Uno using the following pin connections, as shown in the images below….

Python Data Visualization

Python Data Visualization

In an earlier post, python was used to generate an image from datasets. That method lacked the full features needed to create a final image. This post will introduce Plotly as a preferred method. It offers more options and is targeted for use as a tool for dataset visualization. First we’ll need a dataset that is tangible. In this post the dataset will be generated from a field scan to create an image array. The device used to scan the…
