Hopefully a few of you out there have some experience with wireless power and can help me get started with this.
As part of my Robot rebuild I will like to try my hand at wireless power/charging. I have used a charging dock in the past and while it works wireless power would be cool and I won’t have to worry about direct contact and polarity. http://mobilewill.blogspot.com has my projects with pictures of my charging dock. I haven’t posted pictures of what my new robot will look like yet. But it is based on this http://www.sparkfun.com/products/10336
I found a few how to’s to get me started a still a bit confused.
Here is one of the ones I found that seemed to get good current draw.
2-3 inch distance
as close as possible to 2A (I know that is probably pushing it)
<=12v on the remote side
I will be charging 2 batteries that are on-board and have their own charging IC. Just need a power source.
So my question is how do I figure out turns/size for the required current? Is the example above a good way to get AC power?
I did some searching and not understanding the DC-AC conversion and turns/size.
Also some examples like above don’t use magnet wire, but regular wire. So what wire and what size?
I know its a lot of questions, but maybe someone can offer a enough for my brain to put it all together?
Note: Unfortunately I don’t have a oscilloscope. Its on my list of stuff to get one day.
Thanks for the help.
