Slot Car Computerized Lap Timing and Counting


SensorTrak & SensorTrak Lite	SensorHarness Lite

Jan 23 2010
For the new year I lowered the price on the SensorTrak Original and Lite versions.
My USB Interface has been in testing for almost 2 months now with only slight issues, I'm working on a web page for it now.

Hello everyone, I have to clarify something with my USB interface.
It does NOT include sensors, it is just a parallel to USB interface.
To use it you must unplug your EXISTING sensors from the parallel port on your PC and plug it into the DB25 connector on the interface. Then take the included USB cable and connect the interface to your computer. My SensorTrak and USB Interface are SEPARATE items, I’m trying to design the Interface so it will accept any sensors not just my SensorTrak.

I finished the prototype for my USB interface.
At the moment it only works with Laptimer 2000 but I hope more apps such as UR3 and Race Manager X will support the HID protocol used to make the interface.
The final version will be available in several configurations.

4 lanes.
4 lanes with call switch & power control.
6 lanes.
6 lanes with call switch & power control.
8 lanes.
8 lanes with call switch & power control.

I'm working on a FAQ for my SensorTrak, please provide feedback.

I have also started work on a new interface that I hope will bring Slot Car timing into the 21st Century and allow new computers to be used as timing machines. I will give more info when I have finished the prototype. However a new interface will be useless unless there is a timing application to use it, I hope I can convince one or two of the current application developers to adopt my interface.
