Hello all,
I am new here. So you see where my lack of understanding comes from; my background is as a Mechanical Engineer and I'm currently in my masters year. I haven't touched electronics since A levels but I was hoping somebody could point me in the right direction. These forums tend to have a policy of helping people figure things out by themselves and I welcome that with open arms so I'm just asking for pointers and a little patience :)
I'm trying to come up with a simple circuit that charges a capacitor with kinetic energy, preferably using a magnet. My initial thoughts are using a wire coil with the magnet to create a voltage but if you can picture a magnet in a sealed tube with a coil inside it and you're shaking this thing you'll presumably be creating an AC current if the coil is connected to a circuit. So my first question is can you charge a capacitor with an AC current utilising other components and my second question is, if not, how would you create a DC current with the coil and the magnet scenario so as to charge the capacitor and get it to store the charge for a period of time.
If what I'm saying is gibberish to you knowledgeable people I'll try and rephrase.
Thank you kindly for any responses,
Iain
