Thank you to everyone for the encouraging words and guidance. Here is a link to a few pics, along with one of my road course and one of my garage ornament. photos.app.goo.gl/PxwXO8AGib200RLW2Very very nice set up you have there.......all of it !!

OK I pulled together all my part numbers. Here is some info. on how I did mine hopefully to save some time and trouble. I started from scratch and did it trial and error till I got it where I wanted it. My material list consisted of perforated board for from Radio Shack, 28g solid wire, 2.2 ohm resistors (2 per board), 5mm blue IR emitters (8 per board), male and female crimp spade connectors, epoxy, shrink wrap, and 5vdc phone charger transformer. If another voltage power supply is used, the resistor will need to be changed to the correct ones. I will give you a link for an LED series/parallel array wizard. Trackmate has the pre made IR emitters that come with charger and already on the board. Just have to be mounted on a gantry. I tried those on a friends track and found them to be a little weak. The gantry had to be dropped pretty low to the track. The ones I have built are much better IMHO. No problems with them at this point. They have performed very well. The emitters are mounted on the board in 2 groups of 4 directly over each of the sensors. There are 2 resistors per board, 1 for each set of 4 emitters. I will list all the info. below. I am not an electronics technician....in fact you could probably say that this is my first ever electronics project. So anybody can do this. I would be more than happy to help with any questions. The first ones that I built several years ago are still operating on my track for the Start and Finish lines. Also, all of these components are very cheap.....just pennies. Digikey was just the supplier that I found and they were easy to work with. The replacement IR sensors can be obtained through Trackmate, but they are MUCH cheaper through Digikey and are the same thing. I am using them on my track now. Dark or clear will work. - Digikey www.digikey.com/products/en- #1080-1071-ND LED 5MM GAA1AS BLUE TH (These are the emitters. (8) per board. That is their description on the invoice. 1.2v forward voltage / 100mA forward current. These numbers are needed for the array wizard if you use anything other than a 5vdc supply.) - #2.2QBK-ND RES 2.2 OHM 1/4W 5% AXIAL (These are the resistors. (2) per board. These will need changing if other than 5vdc supply is used.) - LED series/parallel array wizard led.linear1.org/led.wiz** These are the numbers for replacement IR sensors in case you wanted some extra ** - #160-1030-ND PHOTOTRAN NPN 3MM IR DARK - #160-1988-ND PHOTOTRAN NPN 3MM IR CLEAR

Track looks good, is the Olds your garage ornament?

Track looks good, is the Olds your garage ornament? Yeah I just got it back on the road last spring. It was my grandfather's car and had set for 20 years. I think I will be doing the gantrys thanks for the how-to.

FYI.......this is how the Start line looks with the gantry as it is now. I first installed them when the track was AFX. The sky is literally the limit on how you want to fabricate the gantry itself. This was just how I did mine. If I can help with anything just say the word. I am very jealous of all that garage space you have.

Yes I like the garage space, One of the few things I miss about Fla. was my garage which was 40' wide and 32' in depth, plenty of room for a full 1/4 mile. It was an oven in the warmer weather however which was about 8 months of the years down there.

Thank you. I will let you know. Tracks and workspace is my basement.

I bought my IR emitters on ebay, dirt cheap. I have them all powered from a 9v power supply, no issues. You can check to see if yours are working with your PHONE. Turn on the camera in your phone and point it at the emitters. You phone will see if they are on or not. Try this, it works.
Make sure that what every you may buy can operate at the voltage that you need....
