Hi All,
I'm trying to put this circuit inside my drum machine and steal power internally so that I don't need any external power but it's pulling the voltage down to 4.052V from an initial 5.717V.
This circuit takes 24 pulses and spits out 12 as is required by the drum machine.
Is it correct to have unused inputs and outputs connected to GND?
Is there a lower power/better way of doing this?
Have I just reached the limit of power that the internal supply can provide?
I'm using an M74HC74B1 as I don't have an HCT like the example given.
I think that the 74HC should be fine running straight off the main power which is 6V?
The drum machine is a Boss DR-110 and runs off a 9v DC adapter or 4xAA batteries.
The power supply schematic is attached.
Thanks.
