Feedback To Source

@all

In the meantime I wait for the parts I send for from goldmine and I can find the address of the magnetic shield manufacturer.

I will post the first part of my feedback project. I am reconstructing the whole thing to see where is the problem with it and I am taking photos as I reassemble it back according to my last composed circuit of 1.5v running.

This photos are the 1.5v to 12v booster circuit alone on the right side of the breadboard.

This is the plan I will follow to the letter as close as possible.

1.5v running with fedback to the source plan

1. photo of the 1.5v to 12v booster
2. build the 1.5v running circuit
3. photo of the two circuits together
4. test the coil output
5. photo of the coil output
6. determine the resistors needed with the formula to get 1-2volts max 3v
7. check the output is correct
8. include the feedback circuit
9. photo of the feedback circuit added
10. test the whole composition

The magnetic shield information that ELIEVE sent me last year is here:

According to plan steps 2 and 3 are accomplished here.

I tested The transistors 3904, 2222, 9014, 4401 and 3055 with the 1.5v circuit and this time and I dont know why, none worked.
I tried tip31A transistor and it worked perfectly. Running the motor with the 1.5v to 12v booster circuit.

Photos included.

@ all

I have been having problems with the connection. I have been two hours trying to connect.
If this does not show up as a post, there will be no post today.

According to plan again, steps 4 and five are accomplished.

The motor coil gave between 8.5 volts and 11.46 volts while running.
The 8.5 volts were when the battery was getting low.
So this coil gives 11.46 volts with a good 1.5 volts battery.
