Applied Magnetics by Barry Hansen

Barry Hansen enthusiasm for Coilgun Designs has created an EE education portal. Learning Magnetism and Basic EE

Applied Magnetics by Barry Hansen

See the RLC Simulator and Inductor Simulator. By building a Gauss Gun which is like a Solenoid, Electromagnetic Relay or 3 phase contacter, you can learn electromechanics. This may be like a sequential solenoid which makes things move.This leads us to the Linear motor.

There is also a very interesting learning article. PID in Control Systems in reading a DIY levitator design In Popular Electronics May 1996 – James Cicon.

Why build a coilgun?

It demonstrates many basic concepts of magnetic machines. A coilgun is foremost an example of a solenoid. These appear practically everywhere, from car door locks to doorbells.

(Youngsters Should do Basic Electricity Experiments with the Supervision and Guidance of a Technician, Engineer, Experienced Enthusiast or an Amateur-Radio Operator My own interest into electricity-magnetism came with a failed Doorbell in my Schooldays, from collecting gramophone and chemistry lab parts i got escalated to the Iron-n-Copper Age – delabs)

A Surprisingly Accurate Digital LC Meter

An inductance / capacitance meter by Phil Rice VK3BHR, Almost as published in Amateur Radio magazine, April 2004.

A Surprisingly Accurate Digital LC Meter

 LC-Meter“The AADE web site gave details of how their design worked and a circuit diagram. This led me to propose a design using their oscillator, but in a slightly different way. Like theirs, mine would measure the free running frequency of an LC oscillator, then successively apply a known capacitance then the unknown inductor (or capacitor).”

Der hier vorgestellte Nachbau des LC-Meter von VK3BHR, Phil Rice, verwendet einen PIC 16F84 und eine Punktmatrixanzeige. Der Messbereich geht in etwa von 0 bis 10 mH für Induktivitäten und von etwa 0 bis 100 nF für Kapazitäten.
