Clark 'Zapper'

There is plenty of information about this type of device on the internet so I won't repeat it here.

This page is just to provide a simple stripboard layout for making a zapper.


The cathode (short leg) on the LED is at the top (negative).

The 555 timer device should be in an 8 pin DIL socket

Capacitors are ceramic disc type

4.7nF = .0047uF and 10nF = .01uF

Do not forget to break the copper tracks between contacts of the 555

All parts available from and many other suppliers.
