There is a mad scientist in all of us, and the Raspberry Pi allows your inner ant to come out and play. It can be used in a million different ways, like teaching kids how to code. or the creation of wearable technology wearable But sometimes things get weird. Very strange.

The $35 Raspberry Pi is one of the best tools for hobbyists. Once you learn about Pi and start playing with it, you will come across some strange projects. We have already seen the strange things people do with Arduino. so let’s find out what crazy mixes they’ve made with the Raspberry Pi.

Cycle Chaser

Every growing boy dreams of a bike that projects a movie onto the ground as he rides. Not? What do you mean they don’t? You are such a freak. Be normal and check out the Cycle Chaser.

The faster you drive, the faster the animation will play. So if you choose to animate when Pac-Man eats a bunch of dots, then he’ll start pedaling faster rather than faster. Video is displayed from the pico projector from the projector while the Raspberry Pi acts as the brains of the operation.

You can even build this yourself by reading the instructions in Make .

Python Thermal Printer

Who needs ink when the power of heat can make letters appear on a piece of paper? One enterprising father, Wade Wegner, connected a thermal printer to his Raspberry Pi to send messages to everyone in the kitchen.


“Having three young children made me think about how a printer could be fun and useful in many ways (although to be honest I haven’t found it that useful yet, but it certainly was fun),» he wrote in his blog.

The printer can be customized with daily weather scenarios, a daily Sudoku puzzle, and even a scenario from Twitter. Why do it? Because you can.

beer keyboard

At a time when computers are going green, you too should do your part. Some Robofun Create fans took this message to heart and decided to recycle their empty beer cans into a giant keyboard.

These are ordinary letters and keys of an ordinary keyboard, printed on forty beer cans. Click on the jar to print that letter on the screen. The Arduino board and Raspberry Pi perform the function of mapping each bank to the corresponding key. Yes, I’m pretty sure they were thinking about this project while everyone was drinking the last one.

Plant life in the hands of Reddit

When connected to the Internet, the Raspberry Pi opens up a world of new possibilities. Redditor Tylerjaywood decided to put the fate of his plant in skillful hands of crazy minds on Reddit.

He hooked up his irrigation system to a Raspberry Pi, which creates a new Reddit post every day. In the branch, users vote whether the plant will be watered that day or not. Votes are counted at the end of the day and appropriate action is taken. And everyone can watch all this through a webcam. It’s still enabled and you can contribute to the sub-Reddit.

The repository for the PleaseTakeCareOfMyPlant project is available on GitHub in case you want to copy it, sick, plant-hating, tormented beast.

Internet controlled car horn

For more of Reddit’s twisted sense of humor, check out the car horn online prank. Lewis Callaway of Make joined a Raspberry Pi with a car horn and programmed it so that anyone on Reddit could curse the horn.

Hide this little contraption in your friend’s car or apartment and watch their sanity roll very slowly as they try to figure out where the sound is coming from and why someone is doing it this way. Callaway estimates it takes half a day of work and less than $75 in installments. Apparently it’s a smart deal when a lunatic wants to play a prank on someone.


Have you ever thought of a pun that you couldn’t wait to share with someone else? This is what happens when engineers think of puns. They turn it into real projects that make you go, «Whaaaaa?»

BeetBox is a musical instrument that plays drums when you touch a beetroot vegetable in a wooden box. TAKE? Beet. Hit. Haha. Here, go make your own.

The Raspberry Pi and capacitive touch sensor work behind the scenes to detect every touch. A custom Python script for the Pi runs a drum sample based on touch. And the audio amplifier plays it for everyone.

piano ladder

Princeton University should include this in their prospectus. The piano stairs are enough to make anyone in their right mind want to study there. That’s exactly what it sounds like: every step on the stairs will sound like a piano note!

According to the creators, each staircase basically has a lighting-based triplet, made up of a light source on one side and a photoresistor on the other. The Arduino reads the sensors and sends the value to the Raspberry Pi, which plays the sounds.

You can repeat this on any ladder by following the instructions. Ten bucks say you’ll try to replicate that iconic scene from Big by the end.

Make a mistake, get hit by rocket foam [Ссылка удалена]

PaperCut software engineers live in mortal fear of cheating. Each line of code is checked multiple times before being committed. For if they make a mistake, the retribution bot will hunt them down!

This rocket launcher is the enforcer in the PaperCut offices. Whenever a software build breaks, the Raspberry Pi and Python scripts come into play. The message is relayed to Retalation, a rocket launcher that won’t stop until it’s done its mission.

Beware, coders are everywhere. Your bosses may soon have new weapons in their arsenal. PaperCut put Retithiation on Github so anyone can do it.

Twitter Candy Bot

Empirically proven that social networks affect self-esteem, So when someone tweets, reward yourself with candy. What do you mean «why?» This is not the time or place for such questions.

All you need is a Raspberry Pi, a servo motor, and an old cola bottle filled with M&Ms. David has detailed instructions on how to build this.

You can set the Twitter Candy Bot to launch on a username or hashtag, so it might just be useful. But mostly, it’s just a fun, creative Pi project powered by Twitter.

Raspberry Dove Repellent

No, your eyes are not deceiving you, you read the name correctly. There is a real dove repelling device made with a Raspberry Pi and a decoy owl.


Apparently pigeons are a huge problem in Buenos Aires and they are also fearless. To keep them away from his home, Rony Bandini turned a wooden decoy owl into a chic pigeon repellant. It detects the movements of doves that cause the owl’s eyes to glow red and make owl and hawk sounds.

Pigeons are stupid. Fearless but stupid.

Show us more weird Pi projects!

Go to the Internet, we know there are some other strange things. Like this guy who thought receiving a new email should trigger a physical notification. Of course, the 10 different «rings» that we already hear on different devices are not enough.

Show us your worst, readers! Let’s bask in all the strange glory of the internet!
