Hello all. This is the second circuit I've designed so I thought i would get some feedback. I have a pretty solid understanding of motor controllers and my first circuit i made was an emitter follower so i decided to work on a signal source for the motor controller first.
This circuit changes the behavior of a motor to a servo by using potentiometer as a position sensor to provide the signal for switching directions. I used a sine wave generator in the circuit to simulate the signal that is generated by the potentiometer. Obviously the actual signal will be different because the voltage on the signal will change when the motor switches directions. The reason there is a separate voltage source for the motor controller is because this source will be provided by a signal from a sensor to control the slew rate on the motor.
Notes:
Q7 should almost always switch on first.
Q1-Q4 behave like a nand latch
Q5 & Q6 determine when the latch flips ((Voltage > 4.9) || (Voltage < 1.5))
The resistors are are all stock values accept R2 & R4 which are a combination of stock values.
Edit: Already fixed something. I added a 200Ohm resistor above the Q6 emitter to lower the current on Q2's base.
Is there anything I should do to make the operation of this more stable? Are there ways I could simplify this? Is there anything I am missing? Is this fine as it is?
Any feedback will be appreciated!
