    A Redditor Used a Raspberry Pi to Build a DIY Virtual Reality Headset
    https://www.hackster.io/news/a-redditor-used-a-raspberry-pi-to-build-a-diy-virtual-reality-headset-f40dd0d485bf

    Redditor Dungeon_Master_Dan was able to make his own virtual reality headset that has all of the features he wants.

    headset started as Yuneec SkyView FPV (First-Person View) goggles. Those goggles are intended for FPV piloting of drones, and feature a 5” 720p LCD screen. Most importantly, they can accept a video feed from a standard HDMI connection.

    That HDMI video feed is coming from a Raspberry Pi 2 Model B, though Dungeon_Master_Dan says that he would recommend the more powerful Raspberry Pi 3 or 4. IR night vision camera is used to provide the video for the augmented reality functionality. Currently, the desktop environment can be overlaid semi-transparently on the video feed.

    High-Voltage DC Monitoring via Raspberry Pi Zero
    How to use a Raspberry Pi Zero under noisy field.
    https://www.hackster.io/pe2a/high-voltage-dc-monitoring-via-raspberry-pi-zero-9f77ba

    we ensured the Raspberry Pi to read up to 1600VDC by isolating it from the ground and using LC, RC filters.

    Instead of expensive Windows-based industrial PCs, you can use Raspberry Pi Zero that you will not pay any license fees. It is so important for automation companies

    Since there is no Ethernet on Raspberry Pi Zero on the device, SPI-based Ethernet converter is used. DC voltage is provided to read with completely isolated OPAMP. Since there is no analog input device on Raspberry Pi, 12-bit ADC is used.

    A handy utility for creating Raspberry Pi SD card images
    Getting started with Raspberry Pi Imager on a Mac.
    https://opensource.com/article/20/4/raspberry-pi-imager-mac

    There are many ways to buy a Raspberry Pi, and depending on who you buy it from, it may or may not come with an operating system already installed on it. Getting an OS onto a Raspberry Pi is a matter of “flashing” an SD card with an OS image. To make this as easy as possible, the Raspberry Pi Foundation has introduced a Raspberry Pi Imager application, and you can download it for all major platforms. Here’s a quick intro to this helpful new utility.

    Old TVs may not have had large HD pictures, or even stereo sound in many cases, but they did have a certain style that advanced sets today don’t match. If you’d like to get a bit more use out of a retro TV set, here’s an interesting idea from creator “Democracity.”

    An IBM Research–Europe team open sourced a fully-functional microscope design that combines Arduino, Raspberry Pi, and LEGO.

    (via IEEE Spectrum)

    Build A Sophisticated Microscope Using Lego, 3D Printing, Arduinos, and a Raspberry Pi
    https://spectrum.ieee.org/geek-life/hands-on/build-a-sophisticated-microscope-using-lego-3d-printing-arduinos-and-a-raspberry-pi

    Taking a photo of a microfluidic chip is not easy. The chips are typically too big to fit into the field of view of a standard microscope, but they have fine features that cannot be resolved using a regular camera. Uniform illumination is also critical because the chips are often made of highly reflective or transparent materials. Looking at publications from other research groups, it’s obvious that this is a common challenge. With this motivation, I devoted some of my free time to designing a multipurpose and compact lab instrument that can take macro photos from almost any angle.

    Mixed Materials: The imaging microscope design uses a potpourri of technologies and materials, including Lego pieces for its main structural components and 3D-printed cogs and racks to drive its moving parts. Stepper motors, which allow for precise movements, are powered by a motor driver board and controlled by an Arduino board. A Raspberry Pi Zero and Pi camera module are used to capture images. The original design incorporated custom-made control boards and parts printed on a high-resolution printer, but prior to public release the microscope was redesigned to be assembled with off-the-shelf boards and parts that could be printed on less expensive, low-resolution printers.

    The Raspberry Pi camera was an ideal choice because it allows the manual adjustment of critical parameters like ISO settings and exposure time. I carefully removed the plastic casing holding the lens, revealing the CMOS image sensor, and engineered a delicate mechanism to move the lens back and forth in fine steps so I could take high-magnification macro photos. The setup worked well for a while, but it was fragile.

    I removed the lens entirely from the Pi camera. Then I took the objective lens from a low-cost USB microscope and mounted it on another CD-ROM linear actuator

    I switched to a lead-screw mechanism used in 3D printers. Instead of commonly used 8-millimeter-diameter threads, shafts, and bearings, I used 3-mm-diameter components to keep things compact.

    Perfect Angle: The Lego microscope allows for a sample to be placed under uniform illumination provided by an LED backlight module. The sample can then be moved forward, back, left, and right and also rotated to find the desired view. The microscope body can be tilted up and down, and its proximity to the sample and focus adjusted as well to provide different degrees of magnification [bottom]. The focus is adjusted by moving a lensless camera module within a Lego housing, altering its distance from the objective lens at the base of the housing.

    A Raspberry Pi Video Intercom System
    https://hackaday.com/2020/04/27/a-raspberry-pi-video-intercom-system/

    That’s what the engineers over at [Hacker Shack] did with their Raspberry Pi-based video intercom system over on Hackster. Now we’ve seen RPi doorbell projects here on Hackaday before, but it’s the implementation of a full-duplex video intercom system that makes [Hacker Shack’s] project really stand out. (Unless you want to be a bit more secretive). They used a Raspberry Pi 3 Model B with an off-brand Pi camera, but the R Pi branded camera will also work just fine. Couple the camera with a very crisp LCD display, microphone, and speaker and you’re good to go!

    Raspberry Pi Cluster Shows You The Ropes

    Raspberry Pi clusters are a common enough project, but a lot of the builds we see focus on the hardware side of the cluster. Once it’s up and running, though, what comes next? Raspberry Pis aren’t very powerful devices, but they can still be a great project for learning how to interact with a cluster of computers or for experimental test setups. In this project from [Dino], four Pis are networked together and then loaded with a basic set of software for cluster computing.

    Introducing the Raspberry Pi TV HAT
    https://www.raspberrypi.org/blog/raspberry-pi-tv-hat/

    The TV HAT connects to the 40-pin GPIO header and to a suitable antenna, allowing your Raspberry Pi to receive DVB-T2 television broadcasts.

    Watch TV with your Raspberry Pi
    With the board, you can receive and view television on a Raspberry Pi, or you can use your Pi as a server to stream television over a network to other devices. The TV HAT works with all 40-pin GPIO Raspberry Pi boards when running as a server. If you want to watch TV on the Pi itself, we recommend using a Pi 2, 3, or 3B+, as you may need more processing power for this.

    Stream television over your network
    Viewing television is not restricted to Raspberry Pi computers: with a TV HAT connected to your network, you can view streams on any network-connected device. That includes other computers, mobile phones, and tablets.

    Redditor Zen_Kong used a Raspberry Pi to build this Bender personal voice assistant.

    Voice assistants, like Apple’s Siri, Amazon’s Alexa, and Google aptly-named “Assistant,” are all designed to be helpful while also being as inoffensive as possible. You may be able to change the assistant’s synthetic accent and maybe even talk it into telling you a joke, but these assistants are designed by committee and built by massive corporations; the last thing they’re going to do is give the assistant a real feeling of personality that could potentially rub some customers the wrong way. Bender, the robotic smartass from the TV cartoon Futurama, is the antithesis of that kind of safe design. That’s why Redditor Zen_Kong used a Raspberry Pi to build this Bender personal voice assistant.
