Cool uses for the Raspberry Pi

Hackers are buzzing with ideas from Pi-powered arcade machines and drones to the home automation and low-cost tablets. 10 coolest uses for the Raspberry Pi article tells that TechRepublic has delved into the Raspbery Pi’s developer forums, and here’s our round-up of the best ideas so far, ranging from the eminently achievable to the massively ambitious. You can use your Raspberry Pi for example as media streamer, arcade machine, tablet computer, robot controller and home automation controller. Rasberry Pi homepage offers also some more interesting projects like Retro games and a retro joystick.

    Automatic Watering System © Apache-2.0
    Water your garden with up to three sprinklers directly from your water tap.

    This project consists of up to four valves and can control up to 3 sprinklers or other kinds of watering devices. It uses one extra valve in order to be more resistant against valve failure and also implements a leak check if you decide to use the water flow sensor.

    The three watering devices can water up to 3 different areas of your garden.

    Bring-Your-Own-Network Ethical Pentesting Tool

    Inspired by the LAN Turtle 3G, when bringing your own network never worry about an IDS or Firewall blocking your access back to the network.

    It’s a lot of things! Well, it can be at least. Simply put, the P-BON is a penetration testing platform designed with multi-factor persistence in mind. With P-BON, maintaining access to a remote network has never been easier. With the power of a 3G cellular connection, you make sure that P-BON keeps you connected, even if the internet goes out at the target location.

    How to deploy Kubernetes on the Raspberry Pi

    In a few steps, set up your Raspberry Pi with Kubernetes using Weave Net.

    By having the Raspberry Pi as a secure gateway to my home network, I could use my phone to control my desktop and remotely play Spotify, open documents, and a bunch of other fun things. I used an existing tutorial for that first project because I was afraid of piping anything into the command line on my own.

    Build Yourself a Cardboard-Framed Raspberry Pi Tablet for Under $60

    For most people, designing and fabricating a case to house an electronics project is the one of the hardest parts of the entire process. CAD and mechanical design are skills that take years to develop

    These days, people tend to jump straight to rapid prototyping with a 3D printer. But, the reality is that it’s only rapid relative to traditional manufacturing

    In his tutorial video on building a Raspberry Pi-based tablet, Josh of JoshBuilds demonstrates how prototyping can be done much more quickly with cardboard.

    Raspberry Pi NFC Clothes Tracker
    Use DFRobot’s PN532 NFC module to track if your favorite clothes are clean or dirty.

    If you’re like me, then you have a small pile of clothes on the floor that may or may not be dirty. This could include jeans, dress shirts, and barely worn shorts. So how can you tell which clothes are clean or dirty? I came up with a way to track various articles of clothing using NFC and a Raspberry Pi. You simply insert the NFC card into a pocket and then scan it, which bring up information about that clothing item along with an ability to change it.

    As Simon mentioned in his recent blog post about Raspbian Stretch, we have developed a new piece of software called PiServer. Use this tool to easily set up a network of client Raspberry Pis connected to a single x86-based server via Ethernet. With PiServer, you don’t need SD cards, you can control all clients via the server, and you can add and configure user accounts — it’s ideal for the classroom, your home, or an industrial setting.

    Ultimate 4 channel audio recorder
    Portable, 2 channel, balanced input, 24 bit 96khz recording

    Using knowledge gained from the ultimate vlogging mic & knowledge of its mane use patterns, the plan for replacing the venerable Zoom took shape. Basically, merge the microphone preamp of 7 years with the AK4524 circuit. Make it permanently phantom powered, with XLR inputs. The AK4524 can be used as a differential ADC by combining its 2 channels & it’s not a huge drop from the PCM4222.

    Based on the use pattern, it also needs a way to monitor 2 channel audio from another digital source without recording it. Maybe this audio could be injected from WIFI. Another circuit will record TOSLINK output from the computer, at a different samplerate than the microphone audio. This should allow it to be used for the ultimate narration of screen captures, as well as ASMR audio & rocket launches.

    Raspberry Pi Pinewood Derby Replay System

    if you’re familiar with pinewood derby races, they are events were kids or adults build model cars to race down a ramp to see which goes the fastest. While it looks interesting, if these events were to be judged manually, there would certainly be arguments as to which car finished first. To mitigate this problem once and for all, Andre Miron came up with a novel device that not only senses each car at the finish line, but generates an instant replay on a nearby monitor.

    Matrix Voice lets you talk to your Pi

    Matrix Labs has come to the rescue with a Raspberry Pi-compatible Internet-of-Things development board with built-in microphones that can bring custom voice recognition smarts to any maker project. And following a successful crowdfunding effort on Indiegogo last year, the Matrix Voice is now on general release.

    After some research, the Raspberry Pi 3 appeared to be the right hardware for this.

    One of the advantages using the Raspberry Pi are the cheap price, being able to play HD videos, having an ethernet port and support for the GStreamer open source multimedia framework.

    The GStreamer framework with its support for the Network Time Protocol (NTP) provides a solution to playback videos locally while synchronizing them with others. This allows to connect almost unlimited Raspberry Pis to the network while still being able to playback individual HD video files.

    Further, we created a custom deployment system using Ansible to reduce the manual setup for each Raspberry Pi to a bare minimum.
