Model Engine Transistor Ignition

by
TIM-6 Transistor Ignition

For a while I have been looking around at model engine transistor ignition systems. Wondering what to buy or even just build from a circuit design. The I saw the kit that is available from jerry-howell.com (this is actually: model-engine-plans.com). The ignition systems and parts are actually on their sister site: model-engine-ignition.com. I bought a … Read more

Electronic Amplifier

by
Non-inverting operational amplifier

The electronic amplifier is a circuit or element that provides gain. Amplifiers are used to provide a number of functions: Increase or attenuate magnitude of a physical quantity. Transform signals from one physical variable to another (e.g. charge to voltage). Remove DC biases. Provide impedance matching. Care should be taken to ensure: Linearity. Satisfactory frequency … Read more
