circuitbasics.com has a new tutorial on how to interface DHT11 humidity sensor to Arduino board. Sample code is provided Because of their low cost and small size, DHT11 humidity and temperature sensors are perfect for lots of different DIY electronics projects. Some projects where...

by robertgawron.blogspot.com: Not many people know, but in some smoke detectors, radioactive materials play an essential role. Today I will present one of those devices, and my -successful- attempt to reverse engineer it and get the circuit diagram. Nuclear physics applied in smoke...

This project shows a DC-DC buck boost circuit which can produce an output of 3.3V for an input of 2.7V to 4.2V , for example from a Li-on battery. The Circuit uses LTC3440 Buck boost IC which is a fixed frequency boost converter. To get high efficient results, inductor with high...

Michigan State University researchers have came up with a new method for  harvesting energy from human motion using nanotechnology. They designed a low-cost film-like device, a nanogenerator, than can power a LCD display,  keyboard, and some LEDs without any source of electric power, by...

Simple Circuit converts Step/Dir. signal into to double drive CW/CWW Pulse, Mach3 and few Hobby CNC software’s provides Step/Direction pulse output to drive stepper motor drivers. Various AC servo works with double CW/CCW pulse. This circuit is solution to interface such AC...

The Apple II personal computer, which stylized as Apple ][, is an 8-bit home computer and one of the first highly successful mass-produced microcomputer products. It was designed primarily by Steve Wozniak and developed with Steve Jobs. Apple ][ was introduced in 1977 at the West Coast...

Software Defined Radio teardown: R820/RTL2832U Decap Recently there has been much interest in two integrated circuit which were originally designed to receive FM radio and DVB-T TV (as used in Europe). Some enterprising people quickly realised that since they were based on...
