Cool LED POV 2

Ooooohhhh, check out this cool LED POV! You can do current time, signs, and more! Nicely done!

From the pictures you can see there’s a motor on the rotor shaft (with the blue housing), and an additional one below the mounting plate. The first motor turned out have too little power to give the rotor enough speed. So I added another motor and a gear, and put stream line wings on the LED bar. The first motor had the rotary encoder attached, so I left it where it was. The second motor came from a tyre pump that runs from a car cigarette lighter outlet. When I first connected the motor to a 6V lead acid battery, it drew 20 amperes and the rotor almost took off like a helicopter! I figured the motor would run hot in less than a minute and burn out. 6 volts, 20 amperes, that gives you 120 watts! So now it’s running from a power supply on a 3 A current limit, and the supply voltage is around 3 volts.
