This is a simple plug and play mosquito repellent. It comes in very handy.

Step 1: What All You Will Need.

You will need the following:

A piezoelectric transducer

A 1000 ohms rectifier diode

An electric socket

An led

Acrylic

A transient voltage diode 1500W

Two Capacitors

Step 2: Soldering Together

Solder all the components together on a perfboard and add the plug socket

Find a suitable cover for the circuit board to be kept in. I got mine from one of those plug and play electric speakers.
