How and why: a selection of weird Arduino projects


    If engineers have a free moment, then they either miss or take a soldering iron in their hands. Or they take a soldering iron in their hands from boredom and assemble devices like the ones below. For what else, besides boredom, skillful hands and an inquisitive brain, can explain the appearance of a lily issuing a note of “fa”, or a chair that breaks after the eighth squat on it?

    Meet the top weird inventions compiled on Arduino.

    Food for thought: a third of the projects are owned by students of design colleges.

    Singing plant


    It would seem: why should a plant sing? Since it is difficult to answer this question, the project fell into this collection. The author decided to add theremin beauty and fragrance - otherwise the principles of work remained almost the same. The model is based on sensory perception , but with a change in the signal amplitude. So, a user named madshobye attached a touch detector to measure the capacitance and then convert it to a signal.

    For all this, he needed an Arduino board, a Gameduino shield and a home-made shield for sensory perception. To be honest, the author flattered himself by calling the project a “singing plant”. Judging by the video, the plant at best is just sounding.



    Nod Bang System


    Another device about sounds, and literally this can not be translated. The idea is that we pretty often nod to the beat of the music. Andrew Lee decided that a nod itself could be music, or rather, a beat.

    The built-in accelerometer in the headphones responds to nodding, the buttons are responsible for various bits, the Arduino cleans and normalizes the sound, and then broadcasts it to the computer via the MIDI USB interface. By default, nodding sounds like the metronome, and the buttons glow white. But if you click on them, you will be able to create a full-fledged bit. The buttons themselves will, of course, flash beautifully.



    Hugging


    If you believe scientists, then to feel complete happiness you need to cuddle at least 8 times a day. But when you rent an apartment with someone else’s aunt or live alone, then hugging vitamin deficiency develops.

    In order not to disturb colleagues and not to rush at random passers-by, the user under the nickname [kaytdek] created Hugbot - “hugging the cowboy”. The robot will welcome anyone with open arms and, if necessary, will give a lot more hugs than the “daily norm” says.

    For assembly, the author used Arduino Uno.



    Arduino Foil


    Shy foil with an unusual name @> <# !!! - a truly strange project from German students of the International School of Design Cologne Vitus Schuhwerk and Till Maria Jürgens (like Erich Maria Remarque is also a boy). Nevertheless, this thing aroused great interest in the network, because it is like a living one. Thanks to an invisible fishing line, a capacitive sensor, four servos and, of course, an Arduino board, the foil “reacts” to an approaching hand and wriggles in every way.



    Self-destructing chair


    Another, to put it mildly, strange invention belongs to students from the Swiss school of design and art ECAL in Lausanne. DRM Chair - this is the name of the project - will serve as a seat for only eight users. Only not at a time, but sequentially: when the eighth person vacates a chair, a tired seat will begin to self-destruct.

    The built-in sensor detects and remembers that they sat on a chair. After the user has risen, the chair makes sounds notifying about the number of remaining possible squats. When the limit is exhausted, the trigger will start the self-destruction mode: the connecting parts will begin to melt - and the chair will fall apart.



    Auto lacing


    Although the future from the second part of the film “Back to the Future” has already come , the sneakers, as Marty McFly Jr. had, did not appear in the general production. But the user under the nickname blakebevin still managed to design self-lacing sneakers. Using the Arduino microcontroller, pressure sensor and servo, the boots are laced up without the participation of the wearer. But you still have to put on the shoes yourself.



    Name generator for baby


    Unable to reach a consensus on choosing a name for the future child? When there are more than two options, and you can’t throw a coin, Arduino Baby Name Chooser, a project from GeekBoy.it, will come to the rescue. Just enter all the name options in the source code, and then click on the button of this device. With the help of the board and the great random, it will give you a name. If at heart you still hoped for another option, then you can click on the button again, and then again, and again, and again - until the inscription on the monochrome display suits all the discussion members.



    "Maslobot"


    This Arduino robot is a prototype of the Rick and Morty series robot. In the 9th episode of the 1st season, an insanely brilliant scientist assembled a robot for one purpose: to bring oil. Students from Bruface constructed almost the same thing, only they have it a little more, it is controlled by an IR remote control instead of a voice and does not ask questions about the futility of being.

    The device consists of an Arduino Uno, two large and two small servomotors and IR sensors. The maslobot is smart enough not to fall off the table, distinguish oil from other objects and store it for a long time before handing it over to the right person.



    Watch "Game of Shadows"


    The Shadowplay Clock was designed by designers from Breaded Escalope. The watch’s trick is that it shows the time using the play of light and shadow from the user's finger. By default, this is an LED lamp, but thanks to the programmed Arduino board, the LED lamps shine “wisely”. In other words, if you touch the center of the invisible dial, then the shadow of the finger will show the time.

    Yes, beautiful. Yes, original. But obviously strange. The vast majority of inventions on the Arduino are for the lazy and automate the process (the same “Maslobot”). But in this case, for the invention to fulfill its direct function, you need to approach it!



    Looking at these projects, I want to ask: the author, why? But literally in a couple of seconds the answer is itself - but just for the fan. And in general - and why, in fact, not?
