This is the Wailing Siren Kit. This kit will produce a Wailing Siren sound that can be used on tricycles, bicycles, and battery-powered toy cars. It can also be used in models and other games where a Wailing Siren sound is desired. The circuit is based on an LM555 Timer and a CMOS Quad Schmitt Trigger.

This circuit can be built in one night. A small speaker is included in this kit. The PCB is double-sided, plated thru-hole, 1.50" long x 2.50" wide made of .062" FR-4 epoxy glass. It has green Solder Mask (LPI) on both sides with white Silk Screen on the Top side and four mounting holes.

This kit is now available as a "Built & Tested" for a small fee for those that do not want to build it themselves.

This kit does not include the tools you will need to assemble the circuit. You will need tools such as a soldering iron, solder, wire cutters, etc.
