Speedometer with flasher output

The speedometer shows the true scale speed of vehicles and can be used as a reference for setting the speed table of DC-Car vehicles. In addition, to use the circuit as animation on the layout because there is provided an outlet with which the flash can be controlled. This output can also be used as a control output for a servo decoder which then gives a police officer a signal that the speeding offender will be put aside and can receive his ticket .... 

The circuit is built and tested, as sensing device we advise two street system hall sensors for easy build in magnetic tape and Faller wire. However reed contacts or optical sensors  also will do the job.

The speed at which to set the flash is adjusted manually by means of simple a variable resistor.

Different versions displays and speed camera as an option to buy separately.
