The Raspberry Pi 3 is a real treasure trove for anyone interested in robotics and the Internet of Things. Of course, all it takes is a bit of fantasy, patience, and countless hours spent searching the Internet for information on how to perform one or another function.

You still need a few accessories to get things done – boxes (even with a fan), mounting brackets, various sensors, a camera, maybe a small touch screen. It doesn’t cost much anymore.

It is safe to say that assembling your full-fledged computer is inexpensive. This is definitely not a big deal for a robotics fan.

There are rumors that Raspberry Pi computers can be donated to students. It’s a great gift if you can figure out what to do with it.

It is possible to launch the Raspbian operating system and launch the browser. This way, this computer would become the same device as a regular computer.

True, it is not powerful enough to play large video files, but saving resources can achieve this.

I would like to share some ideas on how someone has already used a Raspberry Pi computer.


Robots are one of the main applications of Raspberry Pi. This requires a motor to drive the wheels and a control panel (virtually any mini-keyboard for smart TVs). It’s a pretty simple robot that even 10-year-olds can do.

There are special programs that allow you to program and record a robot’s sequence of actions, so even a primitive robot can perform certain actions, such as going somewhere and picking it up. It can be improved by installing a camera that captures certain objects. Then more and more complex sequences can be devised.

For example, run around the room until a certain object that the robot has to fetch is found. Such a robot requires a battery, but obviously, a simple smartphone backup battery is the perfect fit. There is so much room for fantasy here. After all, the robot can also be voice-controlled. The smarter masters even try to make a small humanoid, a human-like robot.

Home machinery control

There are several mechanisms at home that the Pi computer can control. It’s the light in the room. Just mount the dim lights and connect the Pi to the switches. It is also possible to install LEDs of different colors. This way you can do a disco at home with your current lighting.

Another device is a thermostat. It can increase heat, reduce. So is the air conditioner. Another device is the garage door that the Pi can raise or lower. The Pi-controlled door locks are also easy to make. Home cameras can also be connected to a Raspberry Pi computer and view their recordings.

Some people make the Raspberry Pi computer a tablet or gaming PC, but for the time being, it lacks the power to play modern games, so you have to be content with old games that don’t require a lot of resources and graphics. Either way, the Raspberry Pi is the perfect gift for any tech-savvy teenager.


This is the perfect pastime for every party. All you have to do is stand in front of a special box with your friends, press a button and pose for a few minutes. You can then view and save the photos or simply download them to your phone via Wi-Fi. This is enough for a Pi computer with a connected camera and SD card to store photos.

Additionally, a small 5 to the 7-inch touch screen is required to view the photos you take. How to make a booth itself is a matter of ingenuity. It is not very large, so it can be made from simple cardboard or solid wood board.

Calligraphy apparatus

It is a bit more sophisticated as it requires custom software to move the pencil or other pens according to what is programmed. Everything works quite simply – the Raspberry Pi PC application transmits wirelessly or via Bluetooth, which the moving pen needs to depict on a paper or other surface.

It can be drawing, drawing, text. This machine also works well with a laser engraving mechanism, which allows you to engrave a variety of notes on tablets or metal. Useful at home and in the industry.

The desire to convey synthesis – the emergence of multiple senses at the same time – is quite common among people practicing arts. Hardly any of us has ever seen at least one show when a musician improvises on the piano while a painter standing next to him sketches his music. Or the dancer creates a dance. Or (who is crushed here?) The dancer dances while the artist draws.

A logical step in advancing technology – to include a robot in a show – can raise many intimidating questions about the use of culture or a lack of artist-genius, but for now, let’s leave them to the future and just get to know hArt, a robot tends to change colors, ie draws an abstract picture that conveys the moment of the work.

The robot moves based on the information sent by the sensors about the melody played on the keyboard and about the environment (heat, humidity, motion, brightness). The result is a little different from most digital design work, where minimalism and abstraction have become the norm.

So while the robot is not yet sharing its answers, one of its creators, economist and practicing pianist Gianmarco Merlini, who is currently working intensively on hArt presentation at Maker Faire Rome, October 12-14

The DEKO DKSD28Q1 sander is one of the most sold and has already been purchased by over 5,400 buyers, leaving almost 3,200 reviews and a high 4.6 rating.

What makes this grinder so special that so many buyers are interested in it? First of all, exceptionally good value for money. At this price you won’t find an adjustable speed eccentric sander in Lithuania with instantly added sanding pads – the cheapest models that have similar capabilities will cost more, but more realistically you will have to spend more.

Another advantage is the high popularity of the sander. You can find a lot of testimonials, reviews and make sure such a thing really works the way it works. For the cheapest Noname sander, you will not find such information.

The DEKO DKSD28Q1 sander is compact and easy to use the machine. Below are all its technical specifications and what’s included in the package.

In addition to the DEKO DKSD28Q1 sander itself and the operating instructions, the pack includes 15 sanding pads, dust collectors and more.

The latter is a particularly cool feature. Dust will not fly around and cause no additional dirt or airways.

And with 6 different sanding speed modes supported, the DEKO DKSD28Q1 sander can be used on a variety of surfaces and applications.
