I just tested out a car drone charger. It is as I thought, it works in a car when the car is on but it will not work off of a car battery by itself, so I need a way to boost the battery voltage. A car battery ranges from between 0 and 12.6 volts. I need to a converter which will take car battery voltage and put out a voltage of between 13-16 volts. The car drone charger can take between 13-16 volts.
I need a battery supply that can output 120 volts because my drone battery charger runs off of house hold current. I thought I could plug the drone charger into an inverter which is plugged into the car battery, but I am having problems with the voltage dropping too far.
I saw a video of this on the internet and then my brothers and I decided to recreate it. You put a rubber hose on a speaker which vibrates at 24 hertz. Then you record with a camera at 24 fps. Next time I want to find a way to make the hose spin in a circle so it makes a spiral. How could I do this? https://youtu.be/EeY07HYt4uM
