Atmel joins NXP, ST, Luminary Micro (now TI), and Toshiba as a microcontroller vendor to use the ARM Cortex-M3processor core. As a presumed replacement for some of their ARM 7 based MCU products, Atmel`s first Cortex-M3aims to differentiate from the rest by.... -
There are plans to make it 1Gsps in the future, using interleaved ADCs and staggered clock, but that`s beyond me at the moment, so the first iteration will only have 100Msps (fastest from single ADC). The part I`m most unsure about is the analog front end,.... -

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
