RaspberryPi 4 International Space Station Tracker Apr 09, 2020

Show notes

Reminding ourselves that a football-field-sized structure is orbiting around Earth at a speed 10 times faster than what the average bullet leaves a gun, is a good way to keep spaceflight from fading from our collective consciousness. And, although there are apps that can do this for us, tracking when the International Space Station (ISS) is passing right above us makes for a great DIY project. In this video, I combine a Raspberry Pi, a Touchscreen, and an array of LEDs, together with some HTML, JavaScript, and Python, to build a simple Data Visualization device that shows when the next pass of the ISS will be over our location—spoiler alert: it happens more frequently than we might think!

Mechanical Arcade Game with Barebones Arduino Mar 27, 2020

Show notes

Clem reads all your comments on the element14 Community. A lot of people want to save money by shrinking their Arduino projects down to the bare microcontroller! So Clem builds a mechanical arcade-style game by prototyping it on a classic Arduino Uno and migrating it to a standalone ATmega328P with internal 8Mhz clock, to show you the absolute minimum configuration needed to get your project running on custom hardware!

DIY Motorized Zoom for your DSLR Mar 13, 2020

Show notes

Clems Video production is a one-man-show. He has to switch back and forth between being the subject and the cameraman. Constantly moving around the workshop for every single little correction is very tedious. Why not upgrade any common DSLR with a remotely controlled Zoom/Focus? Commercially available motorized zooms and focus pulling devices are very expensive, so Clem develops his own cheap and flexible solution and finds out if is it worth building this sort of camera equipment yourself. What kind of expensive equipment should he try to recreate next?

Automated Raspberry Pi Planet Tracking GOTO Telescope Mar 06, 2020

Show notes

Derek takes a Schmidt-Cassegrain telescope, inertial measurement unit, CCD camera, and a beefed-up pan & tilt mechanism to create an automated planet tracker. Everything is orchestrated via a custom arcade-style controller centered around a Raspberry Pi running C++/OpenCV code to run the UI and control positioning

RaspberryPi 4 Music Player with Analog Controls Feb 28, 2020

Show notes

I love the Volumio music player software for the Raspberry PI, but I am tired of digging through my pockets for my phone to change the volume or pause a song. In this episode, we are going to fix that by adding a bunch of buttons and knobs in addition to a touchscreen display to control Volumio 100% from hardware and without the need for a web browser or app!

Infineon SmartCity Model Feb 21, 2020

Show notes

Everybody likes a new toy, for Clem that means new microcontrollers and sensors! Infineon has a new range of powerful Arduino compatible 32-bit ARM cortex boards and motor driver shields, as well as, sensors! So Clem ventures out to explore them and build a compact demo unit that demonstrates the use of edge devices with 3D magnetic Sensors. It could save a lot of energy in tomorrow's smart cities in the world!

Arduino Love Compatibility Tester Feb 14, 2020

Show notes

As we know, Matt is a sucker for retro novelties and amusement devices, so for Valentine's Day, he wanted to pay homage to the early days of the arcade with a "love tester" device. This Arduino-powered novelty determines a couple's attraction to each other by measuring the electrodermal activity between them and presenting a readout that borrows design cues from the legendary Nintendo Love Tester as well as so many blinkenlight-and-bronze-bedecked wooden cabinets dating back to the heyday of the penny arcade

Super FX Sword using the BBC microbit Feb 06, 2020

Show notes

Frequent thrift shopper, Karen, digs into her to-be-hacked pile and pulls out a plastic sword that has an uncanny resemblance to a piece of the Guts AgroCrag (shout out to the 90s kids in the room!). In this project, Karen uses a BBC micro:bit to level up this toy by adding motion-activated light and sound effects.

Room-Sized Studio Light Speakers Combo Jan 31, 2020

Show notes

Clem likes to hear Podcasts and Music while working on element14presents videos but he’s not keen on using headphones and does not want to pump the volume to max to hear his speakers across the room. So he turns the ceiling of his workshop into a giant speaker, by building Studio panels. These Panels also reduce room noise for better audio recordings and by adding small LED lights act as soft lightboxes for filming. Dragging around big lights with softboxes is not needed anymore for a lot of shots and the right background music helps keep the groove. All in the name of better, faster project videos! Praise the everlasting Din5_180 Connector for its versatility!

Flaming Xylophone Rubens' Tube Jan 24, 2020
