*NOT* Like a BOSS Distortion
Attiny 45 EMF Sensor
The NTE 291 was Cross Reference at NTE with the TIP_31C. I did reverse the diode and added one to the circuit still wont work.
Getting Started with Electronics
I tried everything and can not make this circuit work. My parts list are: NTE291 Transistor, NTE125 Diode, NTE 47K ohm, I am using 9volts. I have also reduced the coil in the picture 10 down to 3 with no luck. I have also tried the same circuit with a 2n2222 resistor and it overheats rite a way.
Thanks switched it to an arduino 101 and it works now. Great project, will follow..
