The Raspberry Pi community recently selected a selection of raspberry Pi’s top projects for 2019, which can be used in real-life cases including grilled cheese machines, robots, hologram generators, and more. Let’s take a look at what whimses can be created on such a small circuit board and what kind of problems can be solved.
Remote control robot for hazardous areas
Loeliger, an engineering student, has created a robot that can be operated by a user wearing a gloved controller. Moving gloves causes the robot to move. Raspberry Pi Zero transmits input to the glove to the robot’s servo drive board. The individual movement of the fingers is controlled by the sheave system, which consists of fishing lines mounted on the servo motor. Loeliger told us that the cost of the entire project was about 300 pounds.
Loeliger is working to add more features, including haptic feedback in gloves, so that users can feel what the robot is touching. He hopes the concept could be used to help first responders in dangerous situations. We can see many use cases, including helping people with disabilities, enabling scientists to handle dangerous materials or shaking hands with someone in a remote meeting.
Raspberry Pi Grilled Cheese Machine
The project was created by a group of friends and students of mechanical engineering at Carnegie Mellon University, taylor Tabb, Mitchell Riek and Evan Hill. Together, they created a grilled cheese maker powered by Raspberry Pi, called Cheeseborg.
The machine is voice-activated and uses Google Assistant on the Raspberry Pi to trigger the process of making grilled cheese. Cheeseborg handles everything from assembly to cooking, and then places the sandwich in the pocket on the side of the machine.
Raspberry Pi-driven Twitter plotter
The project takes old technology to the next level by integrating IoT capabilities. @drskullster, the founders of Liege Hackerspace, and siooner used an old Roland DXY-990 plotter to create a Raspberry Piplotter that can write tweets in real time.
Iooner uses Raspberry Pi to relay tweets to the plotter using HPGL code. You can adjust the parameters used in the source code to select tweets – add specific theme tags and even a list of topics.
Raspberry Pi 3D Scanner
The raspberry Pi is amazingly able to do the work with just a few attachments. Creator Thomas Megel used many extra parts in his project – an open source 3D scanner called OpenScan.
The 3D scanner uses Raspberry Pi to rotate and scan objects. Then, use photogrammetry to create a 3D model of the scanning project. Thomas uses an RPi camera, but is advised to try other options, such as a smartphone or DSLR camera.
Underwater remotely piloted drones
Android developer Ievgenii Tkachenko took his Raspberry Pi into the water, taking the Pi project to a new level. If you grew up with a remote-controlled car, you might have imagined what it was like to fly a remote-controlled submarine – basically what Ievengii created with his underwater Pi drone. It features motion control, lighting and a camera to complete the experience.
Ievgenii’s underwater drone is powered by four motors. To send them a control signal, he designed an Android app to interact with Raspberry Pi. You can use the touch screen to control input, and even the gameboard.
Chord Aid: Raspberry Pi Guitar Assistant
Chord Assist (Chord Assist) project was designed by Joe Birch. It uses a raspberry pistas connected to the guitar to display chord input. It features a refreshable Braille display that sends chord messages, making it easier for visually impaired people to play, learn and tune guitars. The project also benefits hearing-impaired artists, who can read chord output on lcd screens.
Chord Assist uses Google Assistant. It also requires a microphone, speakers and a range of monitors to read the data.
Raspberry Pi Hologram
Now you can also make your own hologram at home. This is what school teacher Dan Aldred did when he created pi hologram machine. It all started watching his students do things like that with old CD boxes and cell phones.
It has four pyramid-shaped acrylic plates (glass is recommended). Holographic video appears on the screen directly above the pyramid, creating a 3D image inside. He uses Raspberry Pi A plus to control the entire operation.
Oracle’s Pi Supercomputer
This is the Oracle Raspberry Pi supercomputer project at Oracle’s OpenWorld Convention in September. This Raspberry Pi cluster project was completed by the company’s team. ”
It has more than 1,000 Raspberry Pis, for a total of 1,060. The cluster consists of racks, each with a capacity of 21 Raspberry Pi 3B plus boards. The system runs the Oracle Autonomous Linux operating system. This project is definitely not built for functionality, but the novelty is exciting.
Plynth Record Reader and Player
If you don’t want to search for your music by typing, why not try recording recognition? The maker, who sp_cecamp on Reddit, has created a Pi-controlled record scanner that allows you to play music by simply putting the record in front of it.
Raspberry Pi takes a picture of the album with the camera before checking the database. Once the album is confirmed, it will play you to any streaming service you choose to connect to. Sp_cecamp labeled the project Plynth.
Raspberry Pi-controlled crane
This is a crane that can be operated by the gamepad controller.
