Hi there,

I have a electronic fly swapper that has a broken handle, and would like to fix it. The new handle doesn't have as much space and i need to remove some elements, on top of that I won't be making use all the elements.

I need your help to determine what I can take off or what are the elements use for so that i can determine to take it out and how to connect the rest.

Attach is a picture of the elements with numbers and one without numbers. Please help determine what this elements are, I don't know much about electronics, but I always wanted to learn. This is my first project.

The device came with a:
- rechargeable battery that output two volts.
- a plug into the wall for charging the battery
- a switch to turn it on
- two push buttons one to activate the electric swapper and one two activate a led

Please HELP!

 

1) Transformer.
2) Capacitor.
3) Capacitor.
4, 5) Diodes; the cathodes are on top (banded ends)
6, 7) Capacitors

None of these items can be removed without destroying the functionality of the board.

Thank you. That helps a lot..

I forgot to mentioned that I have remove the plug to and that the battery and intend to replace the rechargeable batteries with a one AA batteries or two perhaps since the original battery was outputting 2v.

With that I assume since the plug will be removed (is removed) I can probably remove the transformer? since I assume it was used to recharge the battery from the 120 DC on the wall?

The Capacitors are probably to provide a discharge when the zapper is activated with something that conducts electricity? So that I can't alter.

 

I can't see how everything interconnects; and you haven't shown the entire board.

There are at least one, probably two transistors on the board somewhere that switch current to the primary of the transformer to generate a high voltage on the secondary winding. If you remove the transformer, you will no longer have a high voltage output.

They make those flyswatters as cheaply as possible; anything that was possible to leave out, they did. If you take anything else out, it won't work.

 

It's as the Sgt. says: these contraptions often have a circuit like this: not necessarily exactly like what you have, but probably close.

The 120V AC mains input may have charged the battery via a capacitor.
