I am interested in building an inexpensive shift light for a superkart racing application and need any help on designing I can get. Here is what I am thinking (so far):
1. (2) AA or (2) AAA batteries for power source (depending on load needed to meet other requirements. The point is, that AA or AAA batteries should be the power source.
2. Light needs to be clearly visible in heavy direct sunlight
3. Light will come on to maximum of 1500 times over course of one race day and power needs to be adequate for one full race day
4. Wire will be connected to spark plug lead to pickup when a voltage goes through powering the spark.
5. The spark "pulse" needs to be compared against:
a. clock
b. programmed trigger point for light to be greater than or equal to user input value
6. user input trigger point for light will be anywhere between 9,000 sparks per minute up to 12,000 sparks per minute (150 per second to 200 per second)
7. Light will go off after count drops below trigger
8. Size of light(s) needs to be 1" to 1.5" in diameter
9. Cost should be less than $25 total
ANY help is appreciated!!!
