BBC micro:bit board for education was first unveiled in 2015, before starting to be given away to UK students, and later sold for about $19 in 2016. The board supports Bluetooth connectivity, includes an array of 25 LEDs, as well as a specific 20-pin edge connector also featuring 5 large holes (rings) for 3 I/Os and power. So far I had not seen any clones or alternative boards inspired from the design, as we see for Arduino or Raspberry Pi boards. But SinoVoIP (Banana Pi) has changed that with their BPI:bit clearly inspired from the Micro:bit, but offering both WiFi and Bluetooth connectivity via an ESP32 module. Hardware specifications: Wireless module – ESP-WROOM-32 module with WiFi and Bluetooth LE connectivity LEDs – 25x RGB LED array Sensors – 2x light sensors, thermistor, 9-axis accelerometer / gyroscope / compass (MPU-9250) Expansion – 3 digital/analog I/O rings, 3V/GND ring, 20-pin edge connector […]
Gameshell Portable Retro Gaming Console Features Clockwork Pi Allwinner R16 Board (Crowdfunding)
Allwinner R16 with its lowly four Cortex A7 cores and Mali-400MP2 GPU would not normally come to mind when designing a gaming console. But Nintendo used the R16 processor twice in their retro gaming consoles: NES Classic and SNES Classic Edition. Clockwork, a startup based in Hangzhou, China, decided they could also do gaming console with the processor: Gameshell. But their product is quite different, as it’s both a portable console with 2.7″ display, and a development platform with the console based on Clockwork Pi development board, and an Atmel AVR (Arduino) based keypad board. Gameshell specifications: Clockwork Pi development board SoC – Alwinner R16-J quad core Cortex A7 processor @ 1.2 GHz with Mali-400MP2 GPU System Memory – 512MB or 1GB (in future revision of the board) Storage – 1x micro SDHC slot Video Output / Display I/F – 18-bit RGB display interface, micro HDMI (planned in revision of […]

ABC: Basic Connections is a Book Listing Common Circuit Diagrams for Arduino Boards (Crowdfunding)
PighiXXX is known for their very useful and pretty pinout diagrams, but they’ve now created a book called “ABC: Basic Connections” comprised of a collection of easy to read circuit diagrams that shows you how to connect various circuits to your Arduino compatible board. The book is in file folder format, so you can easily remove the sheets you need during your project. While you can normally find pretty much whatever circuits you need on the Internet, ABC book’s diagrams looks very neat, and since it comes with 100 A5 pages of circuit diagrams such as LEDs, decoders, shift registers, 7-segment displays, mux/demux, light bulbs, DC motors, solenoids, relays and so on, you may discover circuits you did not know you needed. Every page of the book also comes with a 0-1.es/xx short URL redirecting to an online tutorial for the circuit with information about the theory, component list, tips, […]
EduExo DIY Robotic Exoskeleton Kit is Arduino Powered, 3D Printable, Designed for STEM Education (Crowdfunding)
Robotic exoskeletons are used for medical purposes such as helping with the rehabilitation of stroke patients, or enable paraplegics to walk again, as well as in the work place to assist people lifting heavy objects. While it’s possible to learn about the theory about exoskeleton technology, practical experience may help grasping all concepts better. However, there are not many courses available, and exoskeletons are usually expensive, so Volker Bartenbach, PhD at ETH in Zürich, has decided to created EduExo robotic exoskeleton kit for education purpose. The EduExo hardware is based on off-the-shelf components like an Arduino UNO board, a motor, and a force sensor, as well as a rigid exoskeleton structure and cuff interfaces. The latter is optional as you can get the kit without it, and will instead receive the STL files to 3D print the parts yourself. There’s also a handbook to help you get started in several […]
