Power Supply Surprises
Posted: Mon Sep 28, 2020 7:22 am
Man, this MTV has a much heavier disk on it. Aluminum vs the Vinyl record I had on my first one. I figured a computer power supply would be great as it would supply the 12v and 5v that I need. When the motor turns on it actually shuts down my Arduino. When powering the Arduino from another supply keeps it rock solid and the motor spins up fine. I even put some decent caps on the board to prevent brownout limited success.
As a side note... want to fry a microcontroller (ATMEGA328) chip very very quickly... forget to put a diode across the motor. Thank goodness I used a ZIF socket.
I will work on a construction diary soon.
Thanks for listening...
