How to Build a Hulda Clark Zapper Video Instructions
Note: There are minor updates to the Build Your Own Zapper Kit. We have adjusted the jump wires for a better fit. We have also pre-soldered the 9-volt battery snap to the on/off switch. These updates are not shown in this video, but are clearly described in the kit instructions. It's so easy to build. No soldering required!

The 555 CMOS Timer is the most likely part to need replacement, so it may be smart to order extras when building a kit.
The 555 CMOS Timer is vulnerable to static electricity. If you walk on a carpeted floor and the 555 receives a static shock it may burn out and need replacement. If you ever touch the 9-volt battery backwards to the battery snap, it may burn out the 555. You may want to protect your 555 by adding a 1N914 Switching Diode to your kit.
