Hello, I just opened up the charger for my Skil screwdriver, the battery is 14.4V and 1.2 Ah .The charger is powered by a 18 V AC 500 mAh transformer ... The big resistance is around 13 ohms, the circuit has the diode and the led and 2 small resistors but also a transistor connected somehow to the led !I measured the voltage at the battery terminal and it is only 5 V C what should I replace in order to repair it?
Amazing robot, this is exactly what I was thinking to do too !Only 2 questions :1. Do you think it is possible to command also the Robot by Wifi in the following way :Remote App sends command via Wi-Fi to Robot Phone and Robot Phone send to Arduino bia bluetooth ? This would make the range of the robot much bigger and maybe it could be controller from bigger distance . Or even via 4G !2. For your current setup, would it be possible to attach the phone to a servo arm and also control that by BT so you can also move the camera up down ?
