The year was 1978 and I was mowing lawns and doing odd jobs around my neighborhood to earn enough money to buy the coolest thing I had ever seen, a TRS-80 Model 1 computer at my local Radio Shack. It was awesome and changed the direction of the rest of my life. I spent all my free trime working with it and doing even more odd jobs to buy all the expansion options. I totally speced it out with a monitor, casset tape drive and eventually the expansion kit with a parallel printer. It started a life long hobby and a carreer that took me all over the county. Such great memories!

An SSH honeypot is a fake SSH server that you can run on your Raspberry Pi to capture bad actors. A user or bot attempting to access your network would get stuck in the honeypot.

Picamera2 WebUI is a lightweight web interface for the Raspberry Pi camera module, built on the Picamera2 Python library and using Flask. This project provides a user interface to configure camera settings, capture photos, and manage images in a basic gallery.

Kiosks are designed to offer users specific information or a specific experience, while preventing access to any other activities on the device. They are often found in airports, shops, hospitals, cafes, and museums — any location where people need easy access to information or services like timetables, waiting times, product information, directions, self check-in machines, and so on.

Whether they are used for powering information displays, automating testing, controlling machinery, monitoring an environment, or doing other tasks, enterprises see Raspberry Pis as serious devices for doing serious tasks. Each model has a long product lifecycle—even the older models (1B+, 2B, 3A+, 3B, and 3B+) will remain in production until at least January 2026. There is little risk that they will go obsolete, so you can maintain a sufficiently large stock and treat them as modular components that you replace rather than fix.

The Internet Pi runs Pi-hole for DNS privacy and ad-blocking, and Prometheus and Grafana to provide Internet connection monitoring dashboards.

The process of changing the DNS server on your Raspberry Pi is a pretty simple process and involves modifying a single file. In addition to showing you what file you will need to edit, we will also walk you through a couple of methods of ensuring your Raspberry Pi is using your newly set DNS.
