This is the American Siren Kit. This kit will produce a sound very similar to an American Police siren. It is uses two LM555 Timers to create this sound which has two adjustments. One adjustment is for varying the rise and fall times and the other is for varying the tone. Use this in your model train setups or anywhere you would like the sound of an American Police siren. The project can be built in one night. A small speaker is included with this kit.
The PCB is double-sided, plated thru-hole, 1.20" long x 2.20" 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 with four mounting holes.
This kit is also offered with a "Built & Tested" option for those that do not want to build the kit 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.
