WOT indicator light?
I thinking of adding a couple of lights to the dash of my car that would be somehow connect to the brake pedal and gas pedal. Something like this shift light but instead of connecting it to the tach connect it to the gas or brake pedal it's self. The idea being that the harder I get on the gas or brake more lights illuminate. I'd like to then mount these on the dash where they'd be visable from the roll bar mounted video camera. So, when at the track, I can review the video and see exactly when I'm getting on the brake and throtle and how hard. Any thoughts on how to do this would be appreciated.

A rheostat (varible resistor) would need to be affixed to each pedal and use that for the input to the signal conditioner. The signal conditioner's output would drive an array of l.e.d.s. Would be helpful if the array was either resistance (0-250 ohm) or current/voltage (1-5vdc/4-20ma) input. I have a known good source if needed.
Nice idea though. At first I'm thinking, you need something to tell you your foot is planted?
Some substantial sucking up to Daniel might net you some results...

I think brakes would be tricky via anything simple. Throttle would be relatively simple, a lot simpler on the S54 cars (already drive-by-wire).
There are probably at least a dozen ways to skin this cat. My opinion of the easiest way? Buy yourself a G-Tech Pro RR and mount it in view of your camera. In the standard 'everyday' screen in road racer mode, it displays lateral G's, longitudinal G's and rpm. It also shows high water marks for G-forces. At 20Hz resolution, it'll store about 1.5 hours of data. At 10Hz, almost 3 hours. Download the data to a PC and you can do analysis.
You can set different maximum levels for lateral and longitudinal G's, and enable the 'G-lights'. The 4 LEDS will hence flash when you're at 80% of the levels you set.
