I said this on another site, why hasn't a noncheating(honest) person that has the knowledge and money build one to show how they work repeatedly and consistently and document the build to keep the playing field level?
All electronics, sensors,wiring visible for all to see.

One replied that he could build one for $1,000 but he doesn't have the time! Lol

Brockmeyer can build one evidently, if he knows what to block!

I'll start a GoFundMe page to hire an electronic engineering firm with no fight in the game to build a tree reader that would show that they do exist OR it's just a fantasy!

I'm guessing everyone here would would contribute at least a buck to keep things honest.

Ok,carry on, I'm behind on making tin foil hats.



Cool

do you think anyone ever expects people who lose round 6 or 7 to be cheating? just wondering as i guess it makes more sense to bow out before they look. i think thats how the guys at lights out do it, cheat until they crash

So some beat their chest about how great racers they are but if someone else does good they must be CHEATING?

I think the term "idiot" would apply to an idiot that would post a link to videos titled cheater over a randomly blinking parking lamp, as if it was proof of something. Roll Eyes

I used to hang around with some people who used to bend the rules in Nascar in the 1970-80's. Their best tactic was to put something blatantly out in the open, and then everyone would focus on that, but not their other fancy part.

Well, it's been a year, let's drag this turd back up for another sniff..... Cool

Scott, any results / findings to report from the '23 season events?

The trend I saw this season is a LOT of good racers who are known for being able to hold and drive the stripe well getting behind for L's when there was no reason to drop at all....have the tree covered and dump to .03 or .04 off. Confused

Lol, I know a guy who said he would put a small light under nose of his dragster and right before he would stage he would turn it on and bump in. He used to do it just to irritate them and possibly throw them off their game. Plus I think he rather enjoyed stirring the pot a little.

I never paid attention to the stage lights after staging, until watching this video. I guess they/we flash the stage lights to counter the tree sensing devices.

I've never seen/noticed that either......but I can't believe I wouldn't react to ANY light flashing on the tree...

What you are seeing in the Video is nothing but an illusion as the Camera shutter speed not set fast enough for the LED lights. You see this all the time with phone carmeras, Its called light source "off" period. Heck watch NHRA and you will see the same thing sometimes with the LED bulbs on the tree or even scoreboards and someone not having the camera shutter speed correctly. Its just an illusion of an issue that did not happen. Had this really happened the timing system would have dropped both lanes red before the tree even came down. Slow the video down and you will see the both lanes the camera being used missed the leds at the same time, just by pure luck the rt lane stages and the camera picks it up. Google camera shutter speeds with Leds. """What shutter speed to avoid flickering lights""""""
This rule suggests setting your shutter speed to roughly double your frame rate. For instance, if you're filming at 25 FPS, you should use a shutter speed of 1/50. This will help to synchronise the shutter speed with the led light's frequency. Reducing the chance of capturing the light source's 'off' period.

I have school buddies son working on this. I asked him if can be done and what would be needed. Figure it might qualify as rocket science and since he worked at NASA for 6 month and makes damn good living working with lazer and devolping new tech for them. He migh be highly qualified to tell me what is needed for the light sensor part of it.

Than it could be som simple now days that anyone into techno world could figure out a system.

Turk, do these "off" cycles occur due to ac power, or do they occur even with dc power?

The off cycle has more to do with the frequency and wave length reflectors of the LEDs then actual power issues. There are cheap and expensive LEDS that run at different frequencies and design. Its not like going and buying and old 120W bulb and all be the same. Use this as an example 50Htz LED means the flow of electrons switch or reverse polarity 50 times per second. the human eye cant see it turning on and off that fast but a camera can catch the off cycle which is exactly what your are seeing in that video. There are a zillion more things that goes into building and LED bulb.

All LED's are DC driven elements, you're seeing the AC current cycle, which is 60hz here in 'Murica, equal to "about" .0166 second to complete the shift.

In testing with a photocell receiver, over 400 tree cycles for the sample, 45 seconds apart, we did in fact observe a .017 variance.

I have said since then that if a timing system designer were serious, they would fire the lamps with DC current.
Even an incandescent lamp doesn't care if the current is AC or DC.
That said, I have lately observed that the Ambers on Compulink don't appear to cycle as they use to.?

Since LED's are in fact DC driven, and every other function of the timing system is DC driven, why wouldn't you use a transformer on the tree lamps?

That's why I set up to be .008 green.

Somebody tag Jeff Foster?

My understanding is that LED cycles are 2x 60hz. Thus 1/120 = .0083, so there can be as much as .008 difference in LED lighting up. If this is true then any tree sensing device should be no more accurate than .008.

Pure DC (battery) power should eliminate the variance, but would allow tree sensing devices to be more accurate.
