Hello Sweat from San Diego

Hello, just joined this great site.. getting back into slots. building my layout and everything is going great... Having some trouble with lighting up the sensors on my timing system. It works with an overhead flood light, but haven't been able to light it with a bridge lighting system yet. Any Suggestions? Looking forward to learning alot from all of you!

Welcome!

And enjoy that new set-up. Post some pictures when you get a chance!

Regarding the overheads:
- check alignment of the LEDs with the photo diodes
- Make sure the photo diodes are lighting up by looking at them with a digital camera. They should show up as blue dots when you look at them on the view screen. turn them on & off to verify that you are seeing them properly.
- Did the LEDs and photo diodes come as a set? The LEDs will emit light in a pretty narrow frequency band, and the photo diodes are usually tuned for a fairly narrow band. If they don't match-up, then they won't see each other. If you still have the packaging, then you might check the specs.

Good Luck!

Hi, Ken!

Welcome to HOSR! A nice place to hang out. Lots of great folks here, with plenty of knowledge.


What kind of flood light? Like a big clamp on light?


I used a couple of these BendBrite lights ( www.nebotools.com ) on my Auto World Drag strip set, with no problems encountered. Usually you can get them at any hardware store (cheaper than the price shown on the website). Do you have room for something like this? It gets a pretty direct light right down on the track. Maybe it would help. It uses 2 CR2032 batteries, that normally come with the light. And the head (lights, switch & batteries) unscrews from the necK, so you can put about anywhere.


When two or more minds are concentrating on the same subject, a 3rd, more powerful mind is created. Welcome to HOSR.

Welcome Ken!

Glad to see you here! John is a very talented man and will steer you in the right direction. We have a GREAT bunch of folks here! I do vintage T-Jets so my notion of a light would be hanging an old shop hand held cage light from a nail in the wall. God Bless! Tony mgbbrown

Yes! It Finally Works...

I can understand the picture of the standalone light.  I didn’t think it was so simple and was putting way too much thought into the wiring.  I thought the LED sensors had to be powered so that’s why in my first post in the other blog I said I fried one.  Thanks JohnsIsland for posting a picture that I can understand and to Tony for posting your old caged trouble light to make it even clearer.  I used a mini clip-on reading light (with a single bright LED bulb) to get LT2K to work.  Testing LT2K with the reading light worked as long as the light was no more then 5” above the track which should give plenty of clearance.  I just ordered 20 bright blue LEDs off Ebay for less then $3.00 (shipping included) so I can build a permanent light holder (is that what a gantry is?).  Now I hope I don't run into the same problem Ken is having (by the way welcome to the site Ken) when I build mine. LEDs are way better then reed switches, anyone need some?  BarryO

Don't you love it...

BarryO when a plan comes together!!! :-) Glad things are working out for ya!!

I have ordered my track with optical sensors, gantry and software for a timing system for the "Fayetteville Motor Speedway" Hopefully I will have a posting on the install of this system from viasue... so far Paul from viasue has been a pleasure to work with... more to come!!!

Well...

Barry O; I was just trying to be funny but I am glad the light bulb turned on so to speak-hah-hah! As you know the most techno-minded thing I own for my slot cars is the pick-up shoe tool you sent me, but maybe the multimeter fits that bill. I am a Ludite at heart-my everyday watch is a 1977 Hamilton Air Force pilot watch and my other two-an early Heuer Autavia for my MGB rally gear and a 1980 Rolex Oyster Perpetual Date I purchased when I got my first archaeologically related job. These do not use batteries either. Riverside has an Aurora electric lap counter and that is as sophisticated as I can be in my vintage slot car world. I do like my computer though! God Bless!

Time gantry...AKA Pedestrian bridge

Welcome to the site!  For my timing system I used this Pedestrian bridge http://www.modeltrainhobbyist.com/bac45172.html  and painted it white.  It fits perfectly over a 4 lane tomy track!  For the lights I used 8 "graing of wheat" bulbs and an old HO train transformer to power them.  (Didn't want to rob any track power).  I mounted the lights in a flat piece of balsa wood (the model airplane type).  I want to switch to LEDS at some point but the bulbs I have in there right now although very bright work great!
