242.1 | Cheap tripods? | BOOKS::GERDE | Cymbal crash 2X only...DTN 237-6302 | Thu May 09 1991 16:22 | 9 |
| As some of you know, our timing light was pulverized during the
GT1-GT2-GT3 race at LRP last weekend. The light was just a halogen
spotlight (fortunately, the receiver was on the pit side and remains
intact), and easily replaceable. However, it was on a small, cheap,
aluminum tripod. Does anyone know where I can find such a tripod?
I've looked in photography magazines, but those are much too expensive
to risk on the track.

Did the blue camaro that went bouncing down the guardrail do that???
You could probably try K-Mart. They should have them in their camera
departments.

| Yes, it was the blue Camaro. He should get a T&S Oh Sh*t award.

| Check out the yard sales coming up. Tripods should be around. A spare
or two won't hurt.
Jo-Ann, are you starting your own O.S. list? Or do you want to add it
to mine???? :-)

| I'm not sure yet, Jim. Probably a little of both.
The difficulty with the tripod is its size. My maximum height for the
timing light is 18 inches. Most tripods are bigger than that before
you open them up.

It may not be the most elegant solution, but have you considered stopping
by a mobile home or RecV center and picking up a "leveling jack?" O.K., they
aren't a tripod per se, they are made of pot metal, but they are cheap and
easily obtained. We used this type solution for several years with our
home-built timer. Currently, we are using a timer from some shop in Atlanta
that was really expensive, but the tripod seems to be a simple, small tripod
that you can pick up at some photography and hunting stores. I've seen this
type tripod used for range finders at shooting events and by some photogs
for a quick set-up and take-down. I've also seen them in some of the
Airline gift catalogues on some planes. You might also try the sporting
goods department at (cringe) K-Mart. As an emergency solution, have you
thought of sacrificing a pylon? Drill a hole in it at the right level,
weight the base and hope for the best. I've tried most of these in over
16 years dealing with different timers, and each has had a measure of
success, even if it only worked once, it got me through.

| Try a table-top tripod, readily available in photo shops for pretty low
prices, also K-Mart. These are about $10.

| how about a cheap jackstand? The kind made out of stamped sheet might
be suitable.
In general I've got to wonder about the safety aspect, things like the
RV leveling jacks or even a tripod or jackstand could be hazardous
under certain circumstances. I'd tend to favor the idea of sacrificing
a pylon as the best choice, it seems the base could be designed to
minimize the hazard if any more cars decide to get up close and
personal with it...

| Given the fact that at NHIS the timing light is on an incline and has
to be aimed at the sensor, a pylon may not be adequate. I believe we
need the swivel section of the tripod as well.
As far as the jackstand, how many Formula cars would like to hit that
sitting on the track at station 12??? Yeah, I _know_ the driver isn't
suppose to be up there, but.....
Besides, given the amount of "stuff" that T&S has to bring to the
track, a small folding tripod sounds right. :-)

| These are all good suggestions...thanks.
I understand LRP will be putting timing light "holes" in the armco
(cart before the horse...etc), so we can be more creative with the
setup there.
As Jim mentioned, NHIS is a difficult case. Because of the incline we
need to have the light almost on the ground...and a LRP we've got to
have it 18" high to account for the track swell at S/F.
I'm trying to set up a demo of an infrared light at NHIS for Memorial
Day weekend...and also again push for an embedded antenna in the track
at the timing line and transducers in all cars -- sure would make my
life easier.

What's the advantage of the IR light over the present setup?
Got a supplier in mind and a total capital cost figure for the embedded
antenna and transducers? There is a Digital business partner with an
existing installation (at Monza) of just such an application, a few
months ago I was attempting to negotiate an agreement with them and
Digital to rep the product here in the US but it never came to fruition
(yet!). If this would be possible I would be interested in following
up on it. Be aware, it is a truely high-end package, but NHIS is going
first class on everything else, perhaps they would be interested.
If that doesn't fly, I've got an alternative scheme that should be
significantly less expensive. I'd be happy to develop it if somebody
can fund it. I'd expect the resulting system would be marketable, at a
reasonably competitive price point.

| .12> What's the advantage of the IR light over the present setup?
There are two major advantages:
1. The present setup (halogen spotlight and receiver) puts
the hardware at risk. Because of the slope on the turn
one or the other (spot or receiver) must be on the track.
I set up the spot on the track, since it's a $15.00 item.
An IR light has a receiver and a reflector. The reflector
would be on the track. Stick-on reflectors cost a couple of
dollars, a tripod would not be necessary, we could stick it
on anything ... cheaper, safer, more flexible.
2. Angle of the sun and reflection problems. Late in the day
at NHIS the lower sun plays games with the receiver, causing
extra hits. We must be alert to this and change the
sensitivity of the timing computer to compensate. It's an
annoyance that would go away with an IR light setup.
.12> Got a supplier in mind and a total capital cost figure for the
embedded antenna and transducers?
Yes, we do. I believe a system was investigated when NHIS was Bryar.
I met with another company this past winter in Baltimore. The track
is aware of what's out there for systems. However, whatever happens
at NHIS pretty much depends on what NASCAR is going to do. In my last
conversation with Ted, I found out that the track is setting up a ton
of computers, modems, comm. equipment that NASCAR needs for their
operation...a distinct advantage for us.
So, I wouldn't be too surprised if an embedded antenna system showed up
someday.
