I've just build it again, and still no luck.
Well, the place that skipped using the base resistor on a NPN BipolarJunction device needs to be avoided.
So how can I fix the circuit? Is my transistor broken?
4x330 ohm resistors in parallel equates to around 82 ohms. Kinda low for 12V current limiting in the 20-50 mA range. What I mean is... they would burn out.
They work on 140mA, and they didn't burn out, because they work if I connect them without the transistor
