A new powerful Raspberry Pi alternative has been launched by Khadas in the form of the VIM3 which is available as both a Basic and Pro version priced at $99 and $139 respectively. The VIM3 uses an Amlogic S992X system-on-a-chip (SoC), the same SoC at the core of the Odroid-N2, which features four Cortex-A73 performance cores and two…
Augmented Arthropod by Grzegorz Lochnicki and Nicolas Kubail Kalousdian is an innovative self-balancing robot that is actually piloted by the movements of an insect placed inside a plastic case using two HC-SR04 ultrasonic sensors. The structure for the build consists of three platforms separated on threaded rod and a couple of rather standard DC gear…
A new open source Espressif ESP32-based board offering a form factor similar to popular single board computers such as the Raspberry Pi Model A / 3 Model A+ has been launched via the Crowd Supply website this month and takes the form of the Obsidian ESP32. Obsidian ESP32 is an Espressif ESP32-based board adopting the familiar form…

Pi-top has preannounced its first mini-PC form factor Pi-top and the first Pi accessory to feature the new Raspberry Pi 4 Model B. The pi-top [4] works more like a portable PC, with the Raspberry Pi 4 encased in a rectangular (and colorful) vessel. Pi-Top is eager to tout the performance advantages of the latest-and-greatest…
A new Raspberry Pi stepper motor and DC bonnet has being designed by Adafruit and is now available to purchase from their online store priced at $22.50. The Raspberry Pi bonnet can drive up to 4 DC or 2 stepper motors with full PWM speed control offering a great solution for robotics, DIY milling machines…
SparkFun has released the company’s first open-source, embedded-systems module—SparkFun Artemis, Engineering Version—to empower engineers, prototypers, and R&D teams to integrate the TensorFlow machine-learning platform into any design. Additionally, the team has launched three boards with the unshielded module: BlackBoard Artemis, BlackBoard Artemis Nano, and BlackBoard Artemis ATP. Built around the ultra-low-powered Ambiq Micro Apollo 3 processor, and powered by…
Radxa recently unveiled many news about its products, adding NVMe support to the Rock Pi 4 v1.4 model and launching a tiny Rock Pi S board for voice applications, and a Rock Pi PoE HAT for adding Power-over-Ethernet to the Rock Pi 4. Rock Pi S: presumably, this will be an open-spec community backed board…
Researchers from Cornell University and the University of Pennsylvania have created a lifelike robotic lionfish with a circulatory system. That circulatory system enables the fish to circulate synthetic blood throughout its body. The blood is a liquid triiodide cathode, which circulates past zinc cells submerged in an electrolyte. As the zinc oxidizes, it releases electrons,…
The Raspberry pi hat, called Enviro+, comes from Pimoroni, which is pitching the add-on as a cheap alternative to expensive environmental monitoring stations. With an additional particulate matter sensor, the Pi-based air-monitoring device can be placed just outside a house. Without the additional sensor, it can be used to monitor indoor air characteristics. “Designed for…
John Kennedy has built a beautiful retro style terminal called FT1 which is equipped with a Raspberry Pi Zero sbc, a cheap LCD screen and usb keyboard. The maker has also provided complete instructions on how to create your very own retro-styled terminal. “This is a brief description of how to build a retro-styled terminal,…
Hardware and software makers behind the Atmos headset want to provide improved accessibility with an open ecosystem, and they aims to do it with a WebVR-capable headset design that is self-contained, 3D-printable, and open-sourced. Their immediate goal is to release a development kit, then refine the design for a wider release. The front of the…
The clapperboard tipically is a device used in video to synchronize audio and video. This creation is an evolved clapperboard that is able to print out posters title, release date and overview of upcoming movies when the clapper is clapped. The poster is not a big, full color job, but rather a black and white…
