Arduino reference for the programming language. Functions, explanations, API descriptions for the base environment.

Basic C for Raspberry PI systems that can be used to drive the GPIO pins to communicate with periferials, such as relays, sensors or even an LCD display. There are specific libraries for standard protocols, but the basics are here.

There are a lot of cheap, mainly chinese TFT LCD devices on the market. They are not always delivered with the driver specified, or it not even specified. There is a good method to detect the driver.

Another TFT LCD idntification helper, in case the previous link did not solve the issue.

Power consumption is sometimes critical. If you need to find the way how to minimize it, here is a good description. The basic logic can be applied to other processors with minor changes.

Sometimes you need higher current to switch that can not be handled by the microcontroller. This is the time for the transistors to step in. Here is a good guide, how to plan it.

When you are ready with the design and it's time to create the final, long lasting implementation, than you need a tool to create your PCB design. Here are some tools compared. Choose one.

A good online PCB designer. This was the one I've choosen finally.

The basis of virtualization is the engine capable to run virtual machines. Like VMWare. I use it run numerous VMs on a single physical server.

You can run virtual instances on a single machine, so called conatiners. This way you can deploy programs together with their environments, making deployment easier and faster. The most popular framework for it is Docker.

Docker gives you large number of configuration possibilities. Docker Compose gives you a tool that makes it easier to maintain through YAML files. This does most of the job, reproducable, fast and easy.

Docker uses images, that you can use to download turnkey implentations. Download the one and start it. Such images are available in a large central collection, called Docker HUB. If someone did it already, you can simply download it and use.

When building your environment with vitual machines, it's good to start it with a firewall to give you a proper control between your networks. This is a good tutorial on how to setup pfSense on VMWare.

For home entertainment, PLEX is a good opportunity. Simply download and start using it via Docker. My advice is to use external volumes configured for your media files, do not store them within the image.

FoldingAtHome is a community tool to support researchers from all around the world. It utilizes the free capacity of your computer to execute complex calculations for scientific researches, such as COVID-19 analysis. You can run it from Docker also to make it simple. Don't forget to reconfigure the system to use your own user if you want to see your own contribution.
