Hey
so I want to build a remote control that uses wifi connection to do the controlling and code is no problem but I having a hard time figuring out how to power the portable remote my requirements are as following
24+ at a usage off (140ma)
https://learn.adafruit.com/low-power-wifi-datalogging/no-optimizations hours lifetime ore 240 if an rpi 3
A plug for recharging / direct powering while Charging
The ability to provide 5v ore 3.3v for a rpi ore Arduino
Charge time dos not really matter that much
Overall size off charging circuit and battery matter a lot
The ability to use a normal phone charger like an iphone charging Brik with a usb kabel
Therefore, this brings up a few questions what kind of battery will be good for this kind of project and size off battery is required (240ma*24houres=5760mah is this calculation off battery capacity right) ?
Anyone know off a circuit preferable a premade one that allows for this kind of setup?
Thanks in advance
