This little device shows you the CPU-load, how much physical and virtual memory is used. It shows this data per 10% on 3 ledbars. To do so it uses a VCP (Virtual COM Port), so that it can be connected to a PC via a USB connection to receive the data. Collecting the data and

This project is named “Engadino” after Engadin – ski resort in Switzerland. The reason for this is that I live in Switzerland, I like skiing and the name is easy to remember and pronounce. By itself the project is a clone of “Pinguino“. “Pinguino is an Arduino-like electronics prototyping platform. It supports different 8- and 32-bit ©Microchip
The purpose of the project was to create an external USB audio card, which could be able to: 1) serve as usual external USB audio card with headphone/line output and audio line input 2) can transmit the digital audio data at relatively long distance (20m -100m) 3) can receive and process the digital audio data

For relatively small (less number of pins than ATmega328) projects, ATtiny series, ATtiny45 or Attiny85 are good choice in terms of its physical size (8-DIP or 8-SOIC) and low power consumption. There are many ways to program it. One of the popular device is USBtinyISP and DASA. Both of them work very well with WinAVR

Thalamus is a small board containing a USB-capable 32-bit 72MHz ARM Cortex-M3 microcontroller, 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer and barometer. Thalamus started out life as a flight controller for the R10 Quadrotor systems, providing stabilization at 400Hz. However, packing a fast microcontroller with native USB capabilities, and with two SPI ports for communications, Thalamus

Introduction: A voltage step-up is a circuit that increases the voltage. It can be AC/AC, AC/DC, DC/AC or DC/DC. This voltage step-up is a DC/DC adjustable voltage regulator. Usually a voltage regulator is fed by a higher input than output voltage, for example 9V IN to 5V OUT. This circuit will take a low voltage

Yesterday I saw the “The Practical Meter” on Kickstarter – a small unit that is placed inline with the USB when charging your phone and shows the actual charging power (in watts) on a row of LEDs. I wanted to have a go at it as well so I did the following last evening. First
