Making my own electric rat trap.

I would like to make an electric rat trap, similar to this one:

https://youtu.be/FyTdCxotVbI?t=240

Questions

Are the batteries connected as parallel?

Is the theory to increase the voltage or increase the amperage? I believe high voltage only stun because I saw a video where a trap was made out of a stun gun. Therefore, if I want high amperage, then do I need to get a capacitor?

What are the two components on the lower right called if I was to look them up on Amazon?

Any other thoughts to improve this trap?

This one seems like it is connected to just a car battery and there is no need for anything else: Any thoughts on this?

The batteries in the first one are connected in parallel. But the circuit board is also important. It seems to be some sort of voltage booster, perhaps a circuit from an electronic camera flash.

Sorry.... that first trap is not believable.
That square device on the right looks like a 6v lead acid battery.
Those round things (Rabbit) look to be batteries but would have to be capacitors.
It could be an oscillator type circuit but would not be powerful enough.

Designs like this need a stack of capacitors and diodes or a HV transformer.

Also.... if the circuit worked.... the rodent would get shocked when he stepped off the cage and onto the Rabbit devices. That didn't happen in the video.

There are a lot of videos just showing a battery. It takes more than that.

If I connect directly to AC 120v instead of a battery, would this be a fire hazard?

If I have a lamp wire plugged into AC 120v and touch the negative/neutral, will I get a shock? Or just the hot black wire will provide the shock?

I would not recommend using 120v line power for a trap.
If you are insulated from ground..... you can touch the hot OR neutral.... not both.

Thanks for the knowledge on electricity like always Pete. I think I will take your advice and play it safe and just buy one from Amazon or Home Depot.

Happy Thanksgiving to you.

In the first video if you read the description is mentions a 5000 volt taser. So that circuit board is likely the guts removed from a taser unit.

It might be the guts removed from a fly squatter. I did see a few where they used a stun gun.

The execution platform must have conductive pads (electrodes) where two of the rat's paws touch two different pads connected to hot and neutral (or positive and negative if DC) respectively. The higher the voltage, the more likely the current will pierce the rat's skin given the moisture level and the exact nature of contact (not fully predictable because dirt or fur in between will degrade the contact).

Take the first link with a grain of salt. The handheld taser units will only run for an extremely short time before overheating. It still looks like a mumbo jumbo of parts. No comments and 3 likes tells you something.
