Recently, the Raspberry Pi community selected the top Raspberry Pi projects of 2019. This includes: a cheese toasting machine, a robotic arm, a hologram generator, etc.
Remote-controlled robotic arm for hazardous areas
Engineering student Loeliger created a robotic arm that can be controlled by a user wearing a gloved controller. Moving the gloves causes the robotic arm to move. The Raspberry Pi Zero transmits the glove’s input information to the robotic arm’s servo driver board. The individual movement of the fingers is controlled by a pulley system made of fishing line mounted on a servo motor. Loeliger told us the entire project costs about £300.
Raspberry Pi cheese toasting machine
This project was created by a group of friends and mechanical engineering students from Carnegie Mellon University: Taylor Tabb, Mitchell Riek, and Evan Hill. They collaboratively created a cheese toasting machine powered by Raspberry Pi, called Cheeseborg.
Twitter drawing machine powered by Raspberry Pi
This project elevates old technology to a new level by integrating IoT capabilities. The founders of Liege Hackerspace, @drskullster (Jonathan Berger) and @iooner, used an old Roland DXY-990 plotter to create a Raspberry Pi-controlled plotter that can write tweets in real-time.
Raspberry Pi 3D scanner
The 3D scanner uses Raspberry Pi to rotate and scan objects. Then, photogrammetry is used to create a 3D model of the scanned object. Thomas used the RPi camera but suggests trying other options like a smartphone or DSLR camera.
Underwater remote-controlled drone
Android developer Ievgenii Tkachenko submerged his Raspberry Pi underwater, taking Pi projects to a new level. If you grew up with remote-controlled cars, you might have imagined what it would be like to drive a remote-controlled submarine – that’s essentially what Ievgenii created with his underwater Pi drone. It features motion control, lights, and a camera to complete the experience.
Ievgenii’s underwater drone is powered by four motors. To send control signals to them, he designed an Android app to interact with Raspberry Pi. You can control inputs using a touchscreen or even a gamepad.
Chord Assist: Raspberry Pi guitar assistant
Chord Assist operates using Google Assistant. It also requires a microphone, speakers, and a set of displays to read data.
Raspberry Pi hologram
Now you can also make holograms at home. This is what school teacher Dan Aldred did when creating the Pi hologram machine. It all started when he watched his students use old CD cases and phones to do something similar.
It features four acrylic plates arranged in a pyramid shape (glass is recommended). Holographic videos are displayed on a screen above the pyramid, creating a 3D image inside. He used Raspberry Pi A + to control the entire operation.
Oracle’s Pi supercomputer
It has over 1,000 Raspberry Pis, totaling 1,060. The cluster consists of racks, each capable of holding 21 Raspberry Pi 3B + boards. The system runs Oracle Autonomous Linux operating system. This project is definitely not built for functionality, but the novelty is exciting.
Plynth record reader and player
Before checking the database, the Raspberry Pi takes a picture of the album with a camera. Once the album is confirmed, it will play any streaming service you choose to connect. Sp_cecamp labeled this project as Plynth.
Raspberry Pi controlled crane
This is a crane that can be manipulated by a game controller.
