3D printed enclosure for a Raspberry Pi and two hard drives

Just a quick one this evening. Here’s a nice 3D printed enclosure for the Raspberry Pi from Paul-Louis Ageneau. It features two bays for hard drives that slide in, together with USB adapters. USB cables then connect the drives up to the Pi’s USB ports and you have a rudimentary NAS. Admittedly, you’ve still got the USB bottleneck to contend with but, if speed isn’t everything to you, it’s a nice solution. You can read more about the concept and download the SCAD and STL files here.

Robotic fish sneaks up on hard-to-track animals with the aid of a Raspberry Pi

There are many sea-borne creatures that are notoriously difficult to film and photograph. To solve this problem, researchers at MIT have developed SoFi, a rubber-encased robotic fish. Mimicking the movement and look of a real fish, SoFi can swim without disturbing the water as much as other methods which can scare away fish and other creatures. To control the robot, the researchers have encased a Raspberry Pi and a Nintendo games controller in an oil-filled rigid outer shell (pictured below) which protects the innards from water pressure. The controller triggers ultrasonic sounds that are amplified by the Pi and are then picked up by SoFi to change direction. You can read more over at Wired.

NuHeat thermostat replaced by Raspberry Pi with touchscreen

Nuheat HOME thermostats cost around $200 a shot. Although very nice, they suffer from being destroyed by electricity spikes. Faced with needing yet another replacement, hacker Sergey has turned to the Raspberry Pi to provide a better, more cost-effective solution.In the end, it was about 25% cheaper and features a Pi Zero W, a 7-inch touchscreen running Chromium in kiosk mode, some power circuitry and analog-to-digital converter and a white picture frame to house the whole thing. The build has been documented thoroughly and you can read how he did it here.

The Teatime Klaxon rouses teenager with the help of a Raspberry Pi

One of James West’s sons has been known not to hear the cry of “tea time!” because of loud music playing in his bedroom. James has come up with a Raspberry Pi solution to the problem featuring a 12V LED tower with buzzer. Using some code from Pimoroni and using one of their Automation pHATs and a 12V power supply, he’s hooked it up to a Raspberry Pi Zero which monitors Twitter for a hashtag. When the hashtag is activated, the lights come on in sequence and the (quite ear-piercing) buzzer sounds. He’s wrapped the wiring inside a wooden box for safety. You can read about the project, and get the code, on his blog and see a video of the final project below:

Multiple movement sensors and a Raspberry Pi can bring a virtual reality game character to life

Jean Perardel has taken several Arduino Fio boards, 6-Degrees-of-Free sensors and a Wii Nunchuck and attached them to his body to detect movement and orientation. The signals are received by an Arduino Micro and a Raspberry Pi is then used to interpret the incoming data and produce a gamified virtual reality representation of the movement which it outputs over HDMI. You can read more over on Hackaday.io and see how one sensor affects the game character in the GIF below:
