Hi,
We have been searching the Internet for answers, but with no luck.
We have an Arduino with a TFT-screen driven by a 9V battery.
Would it be possible to use 5V induction coils to charge the 9V battery?
I am assuming the voltage would have to be boosted somehow, but we will accept any amount of mAh, ie. the time it takes to charge is not an important factor in this matter.
Any setup to get the Arduino running that allows induction charging would be greatly appreciated.
Regards,
Stavros K.
Most of the inductive battery charging circuits are proprietary property of companies that sell the product.
If the output of your induction coil is DC and less than 9 V, then it is a simple matter to boost it. Use one of these.
Adafruit has this set.
The receiver module (single chip) seems to have a DC/DC converter.
Output voltage of those is set by two resistors.
I can just see them (left, top).
Maybe you can replace one resistor, to change the voltage to what you want.

Not surprisingly, there's no link for a schematic.

You seem to be making some kind of point but I can't figure out what that is. Fortunately it doesn't matter to anyone.

It you bothered to read this thread instead of skimming you would know. (since the answer was only 3 posts ahead of the post you were referring to)
