Hi,

i want to control the output of a mosquito electronic zapper circuit with a control knob (like a volume control)


The circuit is similar to this:




Thanks in advance for your help!

It's a gift for someone who has a collection of fly swatters, i'm making a custom dial plate for the knob.

Any ideas for the control?

Since reducing the voltage will also reduce the effectiveness of the swatter, why not just fit a dummy control? You'll still have a uniques swatter to add to the collection.

The last two swatters we made were a wooden swatter with a "retro" look too fragile, and the other was made in sugar as a joke.

I could make a dummy control but a working one is even better.

It seems that everyone worry about possible harm or usefulness of this project (which i explained), but if this goes against the guidelines of this forum let me know and i'll ask elsewhere.

I have one of those. I love it. Never have I ever wished I could turn down the voltage. Not as I listen to the sizzling of my winged foes, not as i watch the smoke rise off their wretched caracasses, and not as I inhale their sweet death stench, never. If anything, I wish I could turn UP the voltage. If I could just watch their evil little bodies explode at my command, I would be willing to pay double for that experience.

Electrocuting insects with less voltage =boring.
Electrocuting insects with more voltage = gratification.

What is the voltage of the battery? Is it rechargeable? Is there any space on the PCB to put extra components like LM317 on it?

I thought about the rheostat with r1 (not sure about the oscillator, i checked on other threads on swatter/zapper for more details)

The voltage is 9v non rechargeable, there is not much space on the pcb but it's still feasible.

What are you suggesting adding?

How about just adding a pot, and a 555 circuit to flash an LED to the handle. The pot would just control the speed of the flashing and not control the swatters output. But no one would know but you. And it would be a completely different swatter for the collection.

The rheostat is the easiest solution for the working swatter.

The led(s) speed/strenght control swatter is also a possibility (more like a vu meter)

Thanks for the suggestion!

The output strength wouldn't need to be changed. No one would know that the bar graph/VU meter and pot wasn't doing anything real but you.:)
