1320racerTree Sensing Devices - The New Hot Topic

December 27, 2020, 01:19 PM
adv ET 266Just stumbled across this. Just some technical thoughts. In order to do this you would need a light detection device. It would need to focus on the top bulb in your lane and exclude the staging bulbs. So many reasons that’s tuff to do in a car and not be visibly obvious.
The only way I see this being technically possible is for a helper in the stands aiming a device at the racers top bulb with something that looks like a camera. It would link to the race car with a radio device. Of course the radio receiver in the car would have a transbrake over ride/Hack.
To detect, one would just need to look for the helper with the racer or cars that are killing the tree. Or, perhaps detect and block radio transmissions around the starting line with a broadband naming device.
Just my thoughts as a electronic expert.

Just as much proof of that as there is about a tree sensing device in this thread. Paging Rudy

wideopen231Lot more evidence on dominion machines than there is on tree sensing devices. Than million have not been spent investigating tree sensing devices.

442OLDSSometimes I ask myself why I bother with Stock Eliminator, and this post makes me appreciate it.
There are some "heads up" races in Stock Eliminator, but it is "mostly " a bracket race.
No one that I am aware of has been accused of using a tree sensing device.If they are using one,it doesn't work very well.
This is not a class where you routinely see a bunch of .00X lights.Just about anybody can usually win,and sometimes people string a few .100 lights together and still get away with it!

Shawn PinkertonIf my wife's new car can adjust headlight brightness by detecting light in front of the car I guess anything would be possible.

GoobI'm not seeing the significance of this time slip.
Odd that the late driver would run under, when the other car is 3 lengths ahead and backing into him hard? Weird but not incriminating.
Crossover error? Just that late?
I'm gonna take a wild guess that the right lane is a high gear launched door car that can run 5.40's or so.....

GoobI have thoughts about how it could be done....and without Crosstalk it's a no go.
By the way, 15 years or so ago there was an outfit in California that marketed a vehicle reaction tester. Based on a light sensor triggering the vehicle launch, for testing purposes. It was large and clunky, and has disappeared from the market as near as I can tell.

banjoSeveral years ago I played around with this using my practice tree. I actually got it to work using a photo electric switch. But I quickly realized how unpraticalable this would be to try to use on the actual track. The biggest problem was changing ambient light conditions. If I dimmed the lights in the room, I had to recalibrate it. Having my TV on in the background creates enough changes in the lighting conditions that it made it inconsistent. Not saying it can't be done, but you would have to have a way to constantly calibrate to changing lighting condition. To try and do it from the starting line to the tree would be very difficult if not impossible.
Here's a little video I did. I was really surprised on how well it worked with stable lighting conditions.
Video I had another idea about possibly using a camera that has motion detect with a relay output. But I think you would run into the exact same issues with changing ambient lighting conditions which would effect how the camera detects motion.

TonyB6255I had a friend tell me he thought people were using the Google Glasses to cheat. I had to Google them to find out what they are but apparently they are basically a wearable computer eyeglass.
I am of the opinion that until someone actually gets caught red handed with a cheating device, it's all just conspiracy theory.

Well said and I agree. Hopefully it is found sooner rather than later.

Forgot to change his dial from 5.40 to 5.97 in the crossover and was .006 natural.
Still don't know why he'd run under being that far behind, but I've done dumber.

I wish a box racer would explain this to me how it shows a sensing device. Just a footbraker here. I've seen some posts in the past with people beating their chest about knowing more than most about racing. Here is a chance to prove it.

LOL
It sure would be sweet to see America back in her prime...
Seriously, clutch pedals the only fix. Say somebody was cheating, you wont find anything unless somebodys willing to tear down a car with a sawzall. I dont see that happening any time soon.
Whatever ya'll decide, do it before i order the fueltech setup this spring... Unless Holley buys them out and turns their products to shyt too...

Mark Cmarits funny , in the 70s it was a known fact that ET wise 4 speeds were more consistent .

SLICKSTERMr.Boucher luv you wagon. We raced at Clay City I was in the black split window. I let go followed the tree down with my eyes,paid attention to the way I left, then paid attention to where you were.You must of carried the front wheels till almost 250 foot. I had full view as I do not remember the spot maybe 1.5 I was thinking like that is bad ass.Yes it would be interesting with a clutch and a air shifted Liberty trans.

Jason HaleyI don't know if cheating happens or doesn't happen. I'm not at these huge races to see for myself because I don't have the budget for it.
That being said, it makes sense for "the same guys" to win these races because those are the guys racing 3,4,5 nights a week anywhere from 30-40 weekends a year. Seat time is something that's hard to beat, especially in a car that has the best of the best equipment and technology.
