The technical note gives the basic information about how the LapSnapper Lap Timing System are used in the slot cars.

LapSnapper Lap Timing System for Slot Cars product includes all necessary components for the two lanes and slot cars except an Android smart device. The system can be build two different ways (2 options):

Option 1: LapSnapper Transponders (Indoor) are installed inside the slot cars

In the option 1 the LapSnapper Transponders (Indoor) are installed inside the slot cars and the LapSnapper Magnetic Strip 1.2 m based magnetic strip are installed below or above the race track. The option works for the unlimited amount of the racers (Slot cars) and lanes. The option can be also handle the lane changes of the slot cars. The option requires that there are enough room for the LapSnapper Transponders (Indoor) in the slot cars.

Option 2: LapSnapper Transponders are installed below the lanes

In the option 2 the LapSnapper Transponders are installed below the lanes and the slot car magnets are installed inside the slot cars. The motor magnet of the slot car may be enough for the operation of the LapSnapper system, if the structure of race track is thin. This means the extra magnets aren’t required to the slot cars. This option is the simplest way to build the system. This option is also good, when there are not enough room for the LapSnapper Transponders in the slot cars. Disadvantage is that the option is not optimal, when there are many racers or the slot cars are changing the lanes.

Please see the technical note about selecting the Android smart device for the LapSnapper. Link to technical note.

Normally the timekeeper is few meters away from the start/finish line. Same time the recommended distance from the LapSnapper Decoder to the start/finish line is 7 to 10 m and the LapSnapper Decoder need to be connected to the Android smart device. This creates a situation, where the distance between the Android smart device to LapSnapper Decoder need to extend. The distance can be extended maximum 30 m by using the USB 2.0 expansion cable or maxuimum 50-100 m by using USB 2.0 RJ45 extender.

TV screen or equivalent can be added to the system by connecting it to the HDMI connector of Android device (Screen mirroring) or by using LapSnapper Client software.

WiFi and lan network is optional in basic installation but it is required, when the LapSnapper Client software, wireless printer or third party race manegement software are used. WiFi network can be build by using WiFi router or by creating WiFi hotspot by using smart device.

The race results can be printed to the paper by using wireless printer. Android printer application is required from the printer manufacturer. Android printer applications are available on the Google Play store.

LapSnapper Lap Timing System supports a LapSnapper Server, which makes it possible to connect LapSnapper Client and third party race management software to the LapSnapper via Wifi or lan.
