Lightning Detector Circuit

Under Category : Detector

Lightning Detector Circuit and schematic This Do-it-yourself lightning detector circuit can be a especially sensitive static electricity detector which can supply an early warning of approaching storms from inter-cloud discharge properly prior to an earth-to-sky return strike takes location. An aerial (antenna) formed of the brief duration of wire detects storms inside a two mile [...]

12V DC Motor Wind Turbine

Under Category : Motor

12 volt Wind Turbine It is possible to use a 12V DC motor (I assume its a car starter motor) as a wind turbine generator to provide energy conversion between the mechanical torque from the wind rotor turbines, (called the prime mover) and the connected 150V load. A gearless two or three bladed upwind wind [...]

Two Speed Contactor DC Motor Controller Circuit

Under Category : Controller

The simplest of all motor controllers (besides a straight on/off switch) is the contactor controller. I designed this contactor controller for use in my electric scooter project. It is based around three 12V relays, two 12V batteries, two switches and of course a motor. Having no silicon to “fry”, it is quite reliable and robust. [...]

Counter Wall 7 Segment Circuit Diagram

Under Category : Led

This simple counter can be used to count pulses, as the basis for a customer counter (like you see at the doors of some stores), or for anything else that may be counted. The circuit accepts any TTL compatible logic signal, and can be expanded easily (see Notes). Counter 7 Segment Schematic: 7 Segment Display [...]
