pt59 Posted October 11, 2007 Report Share Posted October 11, 2007 Hi Guys, I need help, I have just finished my first 'Jigsawed' MDF track, Done in the 'AC2CAR' style of lane layout, I will post Pics soon, But I need to get some lap timing happening, I was running Yascart through a Scaley RMS interface, But now I would like to run Dead strips as each lane passes the start and finish on both sides of the track, Can anybody explain How to hook up dead strips to a computer???

Gyprock Posted October 12, 2007 Report Share Posted October 12, 2007 well I didn't have any lucky with dead strips so I went this way , well I was going to show you but Ican't insert a image Quote Link to comment Share on other sites More sharing options...
pt59 Posted October 12, 2007 Author Report Share Posted October 12, 2007 well I didn't have any lucky with dead strips so I went this way , well I was going to show you but Ican't insert a image I have tried using the scaley RMS unit, wiring dead strips instead of the mechanical switches in the track piece, But I think I may have fried the circuit as one lane is showing a 'dead short' now and does not work anymore, Maybe reed switches might be the go, If so How do I wire up those??? Thanks for the reply gyprock Quote Link to comment Share on other sites More sharing options...
Gyprock Posted October 12, 2007 Report Share Posted October 12, 2007 I'll try and get you a pic Quote Link to comment Share on other sites More sharing options...
Gyprock Posted October 12, 2007 Report Share Posted October 12, 2007 (edited) arrrrrrrrr tha got it and I use laptimer 2000 , not that I know how to use it properly in race modes, never really tried, haven't ever had a proper race with it yet [/img] Edited October 12, 2007 by Gyprock Quote Link to comment Share on other sites More sharing options...
MOPARGREG Posted October 12, 2007 Report Share Posted October 12, 2007 (edited) Hi guys, I to am in the same vote as pt59. I am in the process of adding computer timing. Gyprock - That diagram is very helpful. Thanks. One question though, Where do you place the Phototransistors. Does it matter where on the track. Also as pt59 says in his first post does anyone have any wiring diagrams for dead strip timing Thanks Greg Edited October 12, 2007 by MOPARDEVIL Quote Thanks Greg Link to comment Share on other sites More sharing options...

Thanks for the input guys, The problem is with photo sensors they would be triggered by the car in the next lane, as you can see if you have a look at the album, click on the link and check it out, http://picasaweb.google.com/jupanaho/SlotCarUploadable Quote Link to comment Share on other sites More sharing options...
kalbfellp Posted October 12, 2007 Report Share Posted October 12, 2007 I must be missing something here How will the car in the next lane trigger the sensors IF they are IN the slot?

pt59 Posted October 12, 2007 Author Report Share Posted October 12, 2007 (edited) I must be missing something here How will the car in the next lane trigger the sensors IF they are IN the slot? Phil Check out this link to my pics http://picasaweb.google.com/jupanaho/SlotCarUploadable You will see that the lanes are very close together which means eg Part of car 'A' will pass over car 'B's' slot thus shutting off the light to car 'B' sensor, I am thinking maybe I could set it up so that lap timing is only recorded every second lap and set two sensors just far enough apart so a car will not trigger the wrong sensor! That is why I think 'Mechanical' switches are better for this type of lane layout, Another option may be to Cut a new piece of track and spread the lanes further apart for the start line?

kalbfellp Posted October 13, 2007 Report Share Posted October 13, 2007 If you use IR sensors and transmitters in one piece that sense ACROSS the slot they will work. Like this Photo interuptor.

BMR Posted October 14, 2007 Report Share Posted October 14, 2007 If you use IR sensors and transmitters in one piece that sense ACROSS the slot they will work. Like this Photo interuptor. Do you have a part number or any other info for setting that sensor up in a track Phil ? Also do you know if it has the sensor eye set low or high , Im wondering how it would go if the slot guide blade is only in the slot by 6mm or maybe even a little less ( SCX flag as an example).

That looks like a very good Idea, I will see if I can get hold of some, What other components would I need in the interface circuit? Quote Link to comment Share on other sites More sharing options...
pt59 Posted October 14, 2007 Author Report Share Posted October 14, 2007 Here is a link to UK site that may help a bit with dead strips. Thanks for that, I have now got one lane working using the single sided dead strip via my Scaley RMS interface, Just need to get another circuit board to replace the one I fried with the first dead strip attempt over both rails of the lane, Quote Link to comment Share on other sites More sharing options...
kalbfellp Posted October 14, 2007 Report Share Posted October 14, 2007 Sorry not much more help,I have only used these on a commercial drag track some year ago. I do know that they are from Jaycar and the CAT. NO. ZD1901. The spec sheet is on their site. I drilled two holes down thu the track and opened up the sides of the slot then mounted the sensor from below. It worked fine on the Flashtrack system that we used at the time. They are only $5.00 so worth getting one and trying. I think some here on the forum was playing with them at some time.

rick1776 Posted October 15, 2007 Report Share Posted October 15, 2007 Nice drawing Steve!! Just a little addon bit. The sensor has a arrow symbol with a bar across it on one side indicating which LED leg is which. Connect the 120 ohm resistor to the blunt end of the arrow. The other side has a dot on it. The dot indicates the collector leg of the transistor pick up. The 100 ohms is connected to the "dot" leg. This set up assumes that the software wants to see a 0V to 5V pulse as the car's flag goes through the sensor. I have not built and tested this circuit but built one from individual components and it switched OK. cheers rick1776 Quote cheers rick1776 Link to comment Share on other sites More sharing options...
