Video 1 - Lap Review Mode
A quick tour through part of the menu system. Session summaries with best and average lap times, select a session to review the laps within the session.
Its very simple interface, ok to enter a mode, cancel to exit a mode and up/down to cycle through any options in a mode.
Video 2 - Daylight Laps
One of the challenges with using infra red for lap timing is that daylight will easily saturate the detectors rending them useless. My solution to this is to enclose the detector in a shade however even this isn't enough. To get reliable lap detection with no false laps I have painted the inside of the detector enclosure with 'ultra flat' paint.
The particular paint I have used is manufactured by Krylon and is targeted at hunters, paintballers and airsoft players that want maximum camouflage with no reflection from their equipment. The ability of this paint to suppress reflection stops any daylight from getting to the back of the enclosure. The only light that can reach the detector at the back of the enclosure is light directed directly at it, the light from a lapping car.
Test Car
Tamiya M03 Mini fitted with a Tamiya Sport Tuned motor and good for around 40Km/h.
The lap timer should be good for full size race car speeds, I plan to test at 120Km/h in the next day or two using my daily driver and a long stretch of empty road.
For race car and Kart speeds I will see who I can persuade to test the system at the Dubai Autodrome.
Keeping the cost down.
A standalone Arduino, an LCD screen and not too much else.
Small enough to fit to the steering wheel of a Kart.
More soon...
