It is a newborn board, but it is rapidly growing in popularity thanks to the potential we are going to show you through the project of a robot on wheel that can be controlled by a smartphone via Bluetooth. micro:bit is a small but solid and powerful prototyping board designed by no other…
Arduino Yún board launched in 2013 was the first official Arduino combining Arduino and Linux thanks to respectively an Atmel ATMega32u4 microcontroller, and Atheros AR9331 MIPS WiFi SoC running Linino, a fork of OpenWrt maintained by Arduino. The new Yún has a similar configuration to the original board, and uses the same two processors, making…
This particular (un)locking system, created by Rudec Technologies, is still in the prototyping stage. Actually it is hosted on an Arduino Uno, but the maker is planning to migrate the system on one ESP32 board to develop a small web server and allow for user connections for administration/monitoring of the system. The system uses a…
Emulating hardware on the ESP8266 seems to be a popular thing to do, and it is what MCUhacker did. The x86 CPU emulator is a port of Mike Chambers FAKE86, which is written in C and the maker created an Arduino IDE environment for it. The MS-DOS 3.3 bootdisk image is stored in flash and…
[bctt tweet=”Send alarm email notifications through #Gmail with #ESP8266 ” username=”OpenElectronics”] Based on our ESP03 demoboard, this device sends out email notifications through Gmail when the onboard P.I.R. detects movement. The traditional alarm system which just makes a sound alarm go off and maybe sends out an SMS, forcing you to cash out for…
Plastic Player 2 is an open-source analog interface for digital music. It merges the benefits of digital music streaming with the tactile appeal of physical media. The heart of Plastic Player 2 is a Raspberry Pi running the MusicBox image, which uses the Mopidy server to stream music from a variety of services. But, the…
Yes, I know it…there are already a lot of open source operating systems running on Arm Cortex-M microcontrollers, so what’s different about it? Tock is the operating system specifically designed for (secure) IoT on Arm Cortex-M MCUs. It aims to enable more secure and extensible IoT systems by using a language sandbox and hardware enforced…
IoT application developers are offered a proof-of-concept system by Israeli IoT specialist, SensiEdge. It has released SensiBLEduino, an off-the-shelf, hardware-ready development kit based around the open source Arduino. Arduino is known to simplify the process of working with microcontrollers, providing a solution that is both inexpensive and open source. Developers can combine the Arduino programming language and…
This open source hardware project has been created by developers at Bioblue. The ESP1 is capable of allowing users to control anything with their mind and includes an open source suite of Arduino development tools. Thanks to a lot of sensors the new hardware is capable of helping users meditate as well as boost overall…
Since the Raspberry Pi came on the scene in 2012, the success didn’t take long to arrive. By March 2017, they had sold 12.5 million units, making it the third best-selling “general purpose computer”. But in July 2017, sales reached nearly 15 million! Linuxjournal has just published an interesting overview about Raspberry Pi rivals. “The…
[bctt tweet=”Let’s build a receiver for FM radio with a display to show info such as radio stations, signal power and RDS messages, besides an integrated stereo amplifier with 3 W speakers.” username=”OpenElectronics”] Nowadays, many of us have a smartphone in their pocket to connect with on-demand services like Spotify, iTunes, Google Play…
The ZeroTier Edge is a box that gives you physical (wired and Wi-Fi) ports that allow you to plug things into your imaginary networks. It is a pre-configured plug-and-play bridge with centralized management capability that ZeroTier supports and that can be deployed across an organization. The developers are also using the Edge as an excuse…
