The Connected Health project aims to bring vital sign monitoring to the masses with a simple, inexpensive unit built around commodity hardware. This monitoring system is connected to the Internet, which enables remote patient monitoring. They developed the HealthyPi HAT for the Raspberry Pi as a way of opening up the healthcare and open source…
Developer Cary Wang has created a new low-cost fully featured Vector Network Analyzer that is both easy-to-use and allows S parameter export. The xaVNA two port Vector Network Analyzer offers users a typical frequency range of 137MHz to 3.5GHz, and a guaranteed frequency range of 140MHz to 2.5GHz. It has been designed to plug directly into…
Probably time manipulation is an attractive target for everyone. This project certainly makes it appear that way. YouTuber MadGyver’s glove uses a gigantic LED controlled by an Arduino Nano to allow objects such as a fan, water falling from a shower, and a spinning top to stop, slow down, and even reverse. The trick is that when the LED’s…
Researchers have created a Raspberry Pi-powered robotic lab that detects and profiles the behaviour of thousands of fruit-flies in real-time. The researchers, from Imperial College London, built the mini Pi-powered robotics lab to help scale up analyses of fruit flies, which have become popular proxy for scientists to study human genes and the wiring of the brain….
When the Power Glove was released in the early 1990s, the idea that you could control games with hand motions was incredible, but like the Virtual Boy that followed years later, the hardware of the day just couldn’t keep up. Today, hardware has finally gotten to the point where this type of interface could be very useful,…
When you think about your next project, there’s always something you’d like to improve. Maybe cpu’s performance could be what you are looking for. Microsoft comes to the aid of improving performance with this active cooling system. Testing the Raspberry Pi 3 running idle and after a few minutes of running a compute-intensive AI model,…
The maker community keeps pumping out unique enclosures for the Raspberry Pi, and this steampunk version where the prerequisite gears move may be one of the best. The goal of this project was to have the microSD card on the pi stay accessable, so that the image could be easily updated or swapped out. In…
For anyone with interest in electric vehicles, especially drives and control systems for EV’s, the Endless-Sphere forum is the place to frequent. It’s full of some amazing projects covering electric skateboards to cars and everything in between. Marcos Chaparro recently posted details of his controller project — the VESC-controller, an open source controller capable of driving…
Have you ever wanted to print an animated image? Now Abhishek Singh made it (almost) possible. Inspired by the Polaroid OneStep camera (the SX-70, specifically), Abhishek’s version is called an Instagif and looks almost exactly the same, but instead of printing to film, it ejects a Polaroid-sized LCD that plays back a just-recorded GIF. It’s even…
With Pacer, Faraday Motion wants to provide a set of standard, modular components paired with open-source software for developers and makers to create affordable and simple electric vehicles. Pacer is build on top of the Arduino core for ESP8266 and is running on the NODEMCU ESP8266 WiFi module. Their open-source software allows the chip to connect to a smartphone or WiFi…
We spoke about the integration of 3DR’s Site Scan software platform with DJI drones just a week ago. Now it’s time to introduce you the new Opensolo Initiative: essentially, 3DR has released its SoloLink codebase to the world, for free. By making this vast ocean of resources readily available to the open source community, 3DR has opened…
PolyVection has recently launched the VoltaStream Zero, a hand-crafted and open-source integrated audio module in the same form as a Raspberry Pi Zero. It says the board offers features comparable to Chromecast audio but in a module that’s completely open source. It is possible thanks to its in-built Texas Instruments (TI) digital audio converters (DACs). Their inclusion and its…
