I want to build a handheld electrical device. I have very little knowledge when it comes to electrical components, so that is why I am creating this thread.
The device I want to build is based on magnets.
I want to build handheld electromagnet pulse generator or switcher (what is the correct word?)
Basically, I want to connect battery/DC adapter powered electromagnet to a switching circuit. The circuit switches ON/OFF the electromagnet X number of times. The user should be able to set the switching frequency whether 100 times par minute or 10,000 per minute etc.
Also, it would help if I am able to adjust the power of electromagnet as well.
What kind of magnet, batteries and circuit, IC's transistors etc. would be required for this project?
