I recently bought a wireless gaming mouse and while functionally its great, the battery life is a little less than I would like.
I tried to mitigate this by adding in another rechargable AA battery (as the bay only fits one) but found this wouldn't be possible without grinding away some of the internal plastic, which I'm not prepared to do.
Therefore, I came up with the idea of fitting an induction charging coil within the mouse, with a charger embedded in a custom-built mousemat.
Ideally I would have liked to have made the mat out of aluminium, but after looking into it it seems this would result in interference, preventing proper charging.
What other factors like this are there that I should be aware of going forward with this project?
I'm intending on powering the charger via USB from my PC, would there be current/voltage concerns connecting this? How about in the connection between the receiver coil and the battery within the mouse?
I'm a complete beginner when it comes to things like this, so any and all guidance would be very much appreciated.
