I know that similar questions have been asked here, but none of the answers seem to work for me. Also, I am new to this site, and I am not much of an expert when it comes to electronics, so feel free to tell me if I forgot any important information, or if you need more information and want me to probe at a specific point in the circuit.
I built a Slayer exciter circuit, using the schematic Electroboom used a few years back. Even though I checked my connections a hundred times, I still can't get it to work.
I used a transistor of the type BC637, a diode rated for 1 A, and a self-made inductor.
I used an iron nail as the core and wound around 500 windings around it.
Its inductance is 26.8 mH.
My primary is a piece of thick wire with 6 turns.
I made the following observations:
Nothing oscillates. Wherever I probe, I see no oscillation.
At the base of the transistor, I measure around 0.7 V, more or less, depending on the resistor.
If I disconnect the secondary, probe around it, and quickly close the connection between the base and the resistor, I do see a spike down to around -1.2 V, but if I connect the secondary and do the same thing again, the voltage just goes up to the value of 0.7 V because of the resistor being connected to +.
Any help of what I could do to make this thing work and light up my fluorescent lamp would be greatly appreciated.
It works! I made a new coil with a ferrite core, made around 400-500 windings. The primary is now 4 windings. The resistor is 10kO, and everything works perfectly fine, a CFL close to the end of the secondary lights up.
