Raspberry Pi Python Tool Chain
Introduction I didn’t like Python when I was first introduced to it a couple of years ago. Since that time I’ve learned that it is a great quick-n-dirty language that can be used to build an app or what we used to call a “hack”. The extent of its built-in features and the enormous amount …
Setting up a systemctl service on a Pi
Each Internet of Things (IOT) device in my Do It Yourself Home Automation System (Diyhas) has three elements. Headless Raspberry Pi server with Wi-FI and Bluetooth (Pi Zero W for example) Build and production Python directory structure with my device or subsystem Python modules and a variety of Open Source modules. Boot configuration using systemctl …
Creating a New Headless Pi Server
Introduction Every time I receive a new Raspberry Pi, I go through the same error prone discovery process of creating my personal development environment. I know its going to be Python based with Flask, Paho MQTT, Adafruit modules, my own Python models and a standard pi user file structure. I also setup a “systemd” init …
