Sorry, i guess i wasnt bein very helpful with 'not working' lol
The LEDs are 'fading' on, but then stay on and doesnt do anything else.
The motor seems fine though and is doing what it is ment to do.

Im powering it from the adapter now which is soldered to the circuit, pretty sure that is fine and isnt the problem as it still happens when i put the 9v battery against it.

I have tested the transistor to see if that is ok, and that seemed fine. (conducts like a diode apart from collector to base where it doesnt conduct at all)

LEDs are not soldered in yet and work, just not fading off again.

What other pin do i put the probe on to test pin 8 of the op-amp?

i think im gonna go over the joints of the circuit to make sure none have broken or anything...

 

OK, so it's not the power supply and it's not the transistor.

Put the black probe from the multimeter on ground and the red probe on pin 8. What voltage do you see?

That's a good idea.

After resoldering it all it seems to work now.

That was pretty stressfull.... Lol. Still dont know what caused the problem in the first place, all the pins seemed to show some response with the mulitimeter....Ah well. Will just have to solder more carfully in the future

But at least i have learnt to make some changes to any future PCBs i make.
First of all i etched the circuit electronicly, so it was a bit patchy and had to go over it wit ha dremmel. And secondly, the tracks and pads where too small, so most of the pad dissapeared after i drilled the holes in it.

But i know better now

Thanks for the help guys. Now all i need to do is mount the LEDs in place, solder them on (The right way! Lol) and make the mount for the motor and PCB and then ill be done

 

I don't think anyone that reads this can ever say they did not have that happen. My first boards use to look like utter crud. Good job

Just use a smaller drill bit.

Don't worry about it, just bridge the solder so the lead is soldered to the traks either side of it.
