SolarBoost is an open source smart interface that allows you to build your own powerful and portable solar charger for your phone and other mobile devices. It has two USB ports and can provide 5V @ 2A at each of them and is controlled by a 8-bit 32MHz Microchip PIC microcontroller. It...

Here is a detailed guide on how to get started with ATMega328P microcontroller. The guide goes in details on how to setup it on a breadboard and how to upload your first code on it. and blink a led. The real benefit of using this microcontroller is that it’s only $4 US, whereas...

Dilshan Jayakody has build a low voltage power supply that is able to provide four outputs:  1.5V, 1.8V, 2.5V and 3.3V. This power supply can be used to power low voltage mcus, CPLDs and analog ICs. He writes: In this post we introduce simple and flexible, regulated low voltage...

Espruino is the world's first JavaScript microcontroller. With it you are able to develop intelligent devices quickly and easily. Espruino is a small computer that anyone can use to control things around them. Its JavaScript interpreter gives you instant feedback so that you can...

PULPino is an open-source microcontroller system, based on a small 32-bit RISC-V core developed at ETH Zurich. The core has an IPC close to 1, full support for the base integer instruction set (RV32I), compressed instructions (RV32C) and partial support for the multiplication...

Maurizio @ dev.emcelettronica.com has tipped us with his latest article on how to implement embedded Ethernet on any mcu. The article shows the basic principle of Ethernet implementation. Usually We need embedded systems inside devices, particularly the so-called intelligent devices,...

Bob @ robertgawron.blogspot.com has posted a Geiger-Muller project that can be used with Arduino or any other microcontroller board. The Geiger–Müller counter is a relatively simple tool to measure ionizing radiation. To increase sensitivity, construction presented here contains...

In this video we learn how to use this 8x8 RGB LED matrix. This matrix is using the WS2812 driver and it is great, because each LED is individually addressable. Only one microcontroller pin is required to control all the LEDs, and you get 24 bit color for each LED. 8x8 RGB Led...
