Barry Hansen enthusiasm for Coilgun Designs has created an EE education portal.
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)
An inductance / capacitance meter by Phil Rice VK3BHR, Almost as published in Amateur Radio magazine, April 2004.
A Surprisingly Accurate Digital 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.

LochMaster 4.0 is a developers tool for BreadBoard projects. It has useful functions for designing, documenting and testing project boards.
A Schematic design has been made, either from experience coupled with testing out application note blocks together. It could also be trying out an idea from a Magazine. If you have simulation tools, you may want to simulate parts of the design and iron out some flaws.

Now if this design is small or made of tested blocks and maybe verified by a seasoned designer. Then you can move to pilot production of 7 Nos. If you cannot afford the risk and the cost of iterations. Sometimes making the PCB may delay the design so much, that the “Time to Market” will be too long. Then you lose out to the competition.
So… or Hence or even Thus … A quick Breadboard or Stripboard testing not only validates your schematic, but improves your design skills by making you more familiar with the components and their behavior. The real world limitations and the non-ideal electrical specifications of passives, semiconductors and chips too.
This brings us back to the word Didactic. We should always have both the feet on the Ground. I wrote this note above inspired by the LochMaster, few years ago.
Amicus is a multifunction development system inspired by the popular Arduino board, however, the Amicus board uses a Microchip PIC microcontroller instead of an Atmel AVRtm type.
Amicus an Arduino Like for Microchip PIC
Extension boards add functionality to the Amicus, these boards are known as shields. A shield is a PCB that fits over the Amicus board and provides extra functionality, such as Ethernet, Motor control, LCD, Smartcard, GPS, GSM etc…
Amicus is supported by an integrated development environment (AMICUS IDE).
- Proton Basic source code editor – with colour syntax highlighter
- Compiler – Full version of Proton Basic for the PIC Microcontroller with full integration to MPLAB for debugging, if required.
- Programmer – automated programming of the Amicus Board – no external programmer required.
