few questions...

Regards.

Interesting project that made me want to upgrade my fly swatter too. I also have a swatter with voltage quadrupler output stage (as far as I can recognize circuit topology).

If you are inclined to answer - I have few questions:

• How did CBB 105J2000V output capacitor turned out to be? It seemed strange to me to replace the "fried" capacitor with 10x bigger one. As I understand, the only difference in your design with 105J2000V was adding bleeder resistance (2x 10 MOhm serially connected resistors in parallel with output cap. Does swatter still function to your satisfaction?

• Why not use two 2000V CBB in series as output capacitor? Yes, spacewise it requires some inventive positioning (some elements moved under PCB) within swatter handle, but it might be doable.

• My swatter has originally 3x 22 MOhm 1/4 W SMD resistors in series acting as an 66 MOhm bleeding resistor. You mention adding 20 KOhm resistor to your two 10 MOhm ones as 1/1000 voltage divider. How exactly had you meant to connect it? I am thinking how to create an 1/100 measure point in my swatter, but I am not sure how.

• Do capacitor sizes in voltage quadruple stage matter? I mean - my swatter has 2x 331 3KV ceramics near the transformer and 2x 222 3KV ceramics near the output CBB capacitor. In some designs, I read, smaller near transformer capacitors define the current from the transformer. What would happen if I swapped all four capacitors in quadrupler stage with 4x 332 6KV ceramics?

Finally - thank you for the inspiration and detailed explanations of the ideas and the problems in implementations of those ideas. Regards.
