Updates on the lightsaber prop
In this article I will explain some of the main features of the new lightsaber PCB design and some of my thoughts behind them. I will also give some updates on the other aspects of the lightsaber project. Schematic changes Power distribution While trying to work out how the lightsaber would be powered, I found out that the LED strip consumed 70mA even when all of the pixels were off. Since the plan was to program the lightsaber to go into a low-power mode if it was inactive, this presented a problem. Even if the Nano and the audio amplifier were completely shut down, the lightsaber would still consume power until it was switched off. This also would have required a more expensive switch, since the switch would have to be able to switch the full current of the LEDs. To fix this, I added a MOSFET which could turn the power to the LED strip on and off. I also separated the LED and Arduino/amplifier grounds. This allows the Arduino to be powered through the protection circuit on the
