The Raspberry Pi, although first intended as an inexpensive single-board computer for use in education, is now ubiquitous in electronics communities. Its low price as well as Linux platform and accessible GPIO make it useful in many places outside the classroom. But, if you want to abandon the ease-of-use in favor of an even lower […]

The Arduino is a powerful platform for interfacing with the real world, but it isn’t without limits. One of those hard limits, even for the Arduino MEGA, is a finite number of pins that the microcontroller can use to interface with the real world. If you’re looking to extend the platform’s reach in one of

Arduino enthusiasts interested in creating a changeable RGB LED matrix might be interested in the new Pixie Chroma displays created specifically for the Arduino platform by the engineers and develop and team over at Lixie Labs. Features of the Pixie Chroma displays include Quad Mode and Shortcodes enabling you to quickly create scrolling messages in
Pixie Chroma mini Arduino LED matrix displays from $45 Continue Reading
The Quadrivium EnsembleBot project is a mashup between old school musical instruments and the modern MIDI controlled world. Built by a small team over several years, these hand crafted instruments look and sound really nice. The electronics side of things is taken care of with a pile of Arduinos and off-the-shelf modules, but that doesn’t mean the
THE QUADRIVIUM ENSEMBLEBOT IS A LABOUR OF LOVE Continue Reading
Espressif announces the release of the ESP32-S2 Secure Wi-Fi MCU, which is a highly integrated, low-power, 2.4 GHz Wi-Fi Microcontroller SoC supporting Wi-Fi HT40 and 43 GPIOs. Based on Xtensa® single-core 32-bit LX7 processor, ESP32-S2 can be clocked at up to 240 MHz. ESP32-S2 is a highly integrated, low-power, 2.4 GHz Wi-Fi Microcontroller SoC supporting

Home automation refers to the ability of your home to make its own decisions depending on environment conditions and give you the option to control it from a remote location. In one of our previous tutorial on the ESP8266 WiFi Module, we examined how NodeMCU or any of the other ESP8266 based boards can be used to build a web server

The Etch-A-Sketch was a toy that demanded mastery. Some grew capable of creating masterful artworks, while others struggled to do more than a jumbled mess of angry, angular lines. The inherent limitations of being able to only draw a singular, connected line are all part of the fun, of course, and [gatoninja236] recreated that in a

Back in 2016, FriendlyARM launched the NanoPi NEO Air, an ARM-based board that featured Allwinner H3 processor, 2.5GHz WiFi, Bluetooth 4.0 LE, a camera DVP interface, and a ton of GPIO pins. The board was relatively powerful for it’s Nano size and it now costs around $28. Fast Forward to 2019, we have a new board called

Hi all! Here’s one of the last board I design the last year. On 2016, I develop the Dual USB Serial and I2C Converter board. Although this board works fine, it has a couple of lacks. First one, is that to use the both converters, you need two free USB ports. Is a minor problem

Three open-spec SBCs have been launched on Indiegogo. They are the RK3399-based Khadas Edge SBC, a new Edge-1S model that uses the AI-enhanced RK3399Pro SoC and an Edge-V model that replaces the Edge’s MXM3 connector with 40-pin GPIO and adds MIPI-DSI and -CSI. Shenzhen Wesion’s Khadas project exhibited the Khadas Edge SBC in July, which
