To display the wave I am using XOSCILLO, a very cool and open source tool (which I wrote :P) that converts your Arduino into an oscilloscope. Circuit diagram Here is the scheme, I am using the typical instrumental amplifier(ins amp) and then another op amp to get some more gain. An ins-amp is like an […]

The BareDuino Nano is the world’s smallest Arduino compatible board. It was designed by a very young maker, Niek Blankers, aged 15, from the Netherlands. Niek has been interested in electronics since he was less than 8 years old. A couple of years ago when he was given the first Arduino board, he fell in

with Leonard Shtargot Staff Engineer, Power Products The LT®8610 step-down regulator integrates key high performance features in one compact IC. It offers synchronous rectification, for efficiencies up to 96%. The low quiescent current of 2.5µA extends battery life and saves extra circuitry. High speed switching minimizes board space and helps avoid EMI problems. A low
