  1. That sounds like a great Idea MP, but I don't know how to do that. I don't have a microprocessor. I have no idea what kind to get nor do I have the equipment or know how to program one. I am trying the other method because I have some idea of how to do it. :-\ ???
  2. Thanks for the input MP. OK I thought about the and gate to run the staging lights, I just am unsure where to run the output to to make it start the countdown. either on the 555 or 4017? then any suggestions on a false start light (if the car leaves the mark before the green light comes on if I could work it into the staging lights, space them out far enough that if the car moves one sensor changes state and stop the lights where the are and turns on a red false start light) ??????
  3. I had a schematic with every thing I am trying to do incorperated but most people I showed it to got really confused. alot of it was done on false(incorrect) theory. I chose not to post that cause I didn't want to start out here with every one confused. I am unsure about the Light sensors as to what type and what specs to use. I was hoping to get tthat info here. and LED theory is really kind shady to me last one I tried to use I shot the top across the room ::). freaked my wife out not good. If some one with experiance playing with these types of electronics could help me out it would be great.
  4. I haven't quite figure that out yet, totally. I am going to have sensors on my track, most likely light sensitive sensors. first sensor will be the prestage sensor when they cross that the prestage light lights. then one a little further ahead will be the stage sensor. when they cross that sensor the stage lamp lights. I want it to start when both lights (prestage and stage) are lit the circuit as shown in the schematic will start. I also want to put in a false start so that if they move before the go light(Green) a the false start(Red) will light and stop the circuit. The circuit shown above is of the 3 yellow lights and the green. I am unsure how to implement the rest. That is what I posted for and to see if what I have so far is workable of if there is a more simplified way to do it. I hope this clears up some things and maybe help others see what I am trying to do. :)
  5. ok that cool, I figured my stuff was perfect and didn't need to be changed. Well me and my friends will have to go else where to get help. Thank you guys/Gals sorry if I wasted any ones time. ???
  6. OK here is the schematic so far. I would like to Implement a false start senor and light to this that would stop the circuit if it is tripped. I suppose for the sensor I would just use a photo resistor, for the light a red led but how to wire it in stumps me. I would also light to put in the prestage and stage lights using photo resistors and diodes and when both lights are lit it starts count down. If any one can figure out how to make this work or simplify it let me know.
  7. Hello, I Need help!!! I have been working on this project for 3 months and I have reach a problem on chooseing the right components. (Part Numbers and such) I also need to incoperate a few things I am just not sure how to implement it in with the rest of the circuit. I am building a HO Scale Racing Tree(Christmas Tree) for HO Scale Slot Cars. I have a Schematic drawn out, and uploaded to my computer I can send it to any one who wants to Help. I am doing this as a Hobby and if it works, I would like to post it for others to use I know many others looking for this same circuit. If you feel you can help or would like to give it a shot let me know I will send you a copy of the Schematic. Thanks.
