The Japanese company Nobarus recently released a product crowdfunding project called MaBeee. MaBeee is a small box that can turn AA or AA dry batteries into remote-controlled smart batteries. It contains Bluetooth communication module, after installing the dry battery, you can use your mobile phone to control the batterys switch, voltage and current through Bluetooth.
For example, if you install a MaBeee in a toy car that cannot control the speed (of course, you must first install a dry battery inside), you can change the speed by controlling the output voltage. With the accompanying App installed on your phone, you can start the toy car by shaking the phone left and right, adjust the speed by tilting the phone, stop the car by clicking the stop button on the screen, and start it again immediately by clicking the start button. A series of operations are performed on ordinary dry batteries. Unachievable. In addition to Bluetooth control, the company is also studying the use of 3G mobile networks for control.
