RTSP streaming from Raspberry PI

Introduction

This gist describes the necessary software installation steps for a Raspberry PI in order to enable the PI's camera to act as an external camera for the Dragonfly Java application. This gist shows, how to make a Raspberry PI an RTSP streaming server. The resulting feed can then be used as input for the Dragonfly Java app or the Accuware Dragonfly Demo - Calibration Mode server. The RTSP server on the Raspberry PI must be made publicly available, if calibration is a requirement.

Prerequisites

• Raspberry PI Zero W, 2, 3, 3b, 3b+, 4 with a Raspberry PI-Cam 5 MP or a [SainSmart Wide Angle Fish-Eye Cam](https://www.amazon.de/SainSmart-Fish-Eye-Camera-Raspberry-Arduino/dp/B00N1YJKFS/ref=asc_df_B00N1YJKFS/?tag=googshopde-21&linkCode=df0&hvadid=310638483583&hvpos=1o3&hvnetw=g&hvrand=12314684975119410116&hvpone=&hvptwo=&hvqmt=&hvdev=c&h

Get the synth wave glow working for VS Code on Mac

These notes are pretty much the same steps as the two extensions list, it's just that I had to collate them together because neither seems to list it fully in the proper order.

1. Install Synthwave ’84/Synthwave + Fluoromachine theme on VS Code (I used the Fluoromachine one)

2. Install Custom CSS and JS Loader

3. Command + Shift + P to open command palette > "Preferences: Open settings (JSON)"

Arch Linux ARM 64 on Raspberry Pi 3 B+ With Full Disk Encryption And SSH Unlock: 2018 Edition

There are multiple ways to get a full disk encrypted arch linux system on raspberry. In this tutorial, we will install a 64-bit arch linux armv8 system, using dropbear as ssh server for remote pre-boot unlocking of the root filesystem. However, it will still be possible to unlock and use the pi as usual, with a keyboard and monitor. We will also create an unencrypted partition in the installation process, usable as a rescue system.

Differences to the 32-bit arch linux arm version:

• probably better performance
• can run 64-bit software
• comes without the proprietary video-driver blobs
