An availability of spare electronic components at my home and a project that is due next week has led me to wonder about making a Ruhmkorff coil that can produce good sparks. However, the traditional design demands a mechanical breaker circuit which I think can be easily replaced by a circuit as shown in following figure :
Is the design sufficient or do I need some adjustments to make it work with the available parts ?
These are the parts I currently have:
- TIP31C Transistors
- Diodes (UF4007)
- 48k Resistances
I have already wound a ~900 turn coil for the primary coil made of thin enameled copper wire. The classical design states that a capacitor is good for better performance. I don't seem to have one. Is it really necessary? If yes, what rating would you recommend.
