https://www.kickstarter.com/projects/turingpi/turing-pi-cluster-board The Turing Pi 2 is a 4-node mini ITX cluster board with a built-in Ethernet switch that runs Raspberry Pi CM4 or Nvidia Jetson compute modules in any combination. It's like a data center server rack but compact, noiseless, and highly energy-efficient. It’s perfect for building your own Homelab, self-hosting, running the cloud-native stack (e.g. Kubernetes), and machine learning 24/7. The use cases are limited only by your needs and imagination.

Witty Pi 2 can define complex ON/OFF sequence for your Raspberry Pi. Thanks to the schedule script, you can keep your Raspberry Pi in OFF state, and turn it on only when necessary. By doing so you are saving a lot of energy, which is perfect for solar/battery powered system.
In this tutorial, I will show you how to build a solar powered time lapse camera with Witty Pi 2. The required materials are shown in the picture below:

Latest version has a whiptail admin menu and is Much Faster than the Speed Tracking python script used in this video
This video and code walk through (original slower code) shows my Raspberry PI B2 and python program that measures and records object speeds using Opencv (Computer Vision) and can use a web camera or RPi camera module. Code Now runs on windows and non RPI Unix distros using a USB Web Camera. There is also an opencv template match (find image inside another image) search utility that can find similar vehicles (objects) in the speed search images library. Includes a makehtml and local webserver for viewing speed images and CSV data.
The program is written in python and is available on GitHub. The inspiration was a comment on the RPI forum from a user asking if the camera could be used to measure vehicle speed. Having written a previous motion tracking and associated hotspot game, I decided to take on the challenge as a fun exercise. If you are interested in Raspberry Pi computers and python programming then this might be a fun project to try. The accuracy of the data may vary but my test results have surprised me. Check out some of my other video's since video editing is another one of my hobbies.

https://www.youtube.com/watch?v=mfiRJ1qgToc Welcome to the world's first Computer Vision with Arduino Course. Here we are going to learn the basics of how to create real-world Computer Vision applications using the extremely popular Arduino Microcontroller. We will first start with basic exercises and move on to creating exciting projects such as Lamp Gesture Control, PID FAce Tracking, Angle Finder, Hand Gesture Control, Color Sorter with Conyeor belt, and a lot more. 
The aim of this course is not to create random projects. But to understand the fundamentals and to give you enough knowledge and experience so you can build your own million-dollar ideas. This course has a clear pathway from basic to advanced with lots of practice examples. Links to https://www.computervision.zone/courses/computer-vision-arduino-chapter-1/ 
https://www.youtube.com/watch?v=XUFWE2RbeAc Making the motion detection scripts useful for our Python 3 Cookie Thief detection system. This video is part of a series of building a practically 'useful' security system using Raspberry Pi to catch the Cookie Thief. I am not a computer scientist, software engineer, programmer or electrical engineer. Everything I cover was self taught using resources I found on the web. I thought it would be great to put together a series of videos that consolidates what I have learned to yield a single resource to cover many interesting topics about the Raspberry Pi! Having said that, due to my relatively little experience, I may have made mistakes or could have done certain things better. If you are aware of such a mistake, please let me know either in the comments or through email!

https://www.youtube.com/watch?v=kNpCVfrELYk SPI is an ultra simple communication protocol that is cheap to implement, supports fast 10mbs transfer speeds, and is incredeibily simple to implement in your project. SPI Stands for Serial Peripheral Interface (SPI) and is traditionally used used to send data between microcontrollers and small peripherals such as shift registers, sensors, and SD cards. It uses separate clock and data lines, along with a select line to choose the device you wish to talk to.
