Who can tell me some details for building an Lapcounting system with lasers and photo cells (similar like the system of SimpsonRC)??

If you or some one you know can program, you can use the PC GADGET to plug in some light sensors upto 12 I think.. maybe 10 or so... and then use laser pointers to shine on them, and turn it into a Lap Counter... but you gota program the counter.. or program/edit en existing program to work with it... I been planning on making one, but I suck at programing, so I will probly dictate what I want to some one else ;) I have a PC Gadget... it works nicely... but I aint exactly done much with it...

http://www.pcgadgets.com/ -- I got mine REALY cheap ;) but I had a good deal... they are about 100$ or so... you can do more with it like drive stepper motors etc.. so you culd have a start gate open and close ;) or have the track change randomly ;) a short cut ramp open/close hehehe... silly but fun.

Drac, I could probably do the programming for you, send me the details.

I did my first lap-counter really cheap and I am now making better one, but all this working takes too much time from my hobbies. (and the better one is not that much better (bit more accurate), just a project)

I described the lap counter here: http://mini-zracer.com/forums/showthread.php?threadid=1029&perpage=15&pagenumber=2 .

Maybe I someday get digital camera from somewhere so I could take some pictures (sorry mini-z still no camera)... well ... That version does not even need any programming.

Now I am making microcontroller based timing system and I did one piece of software to use it with glsfr. But if you want easy, low-cost timing system I suggest you do something like in the thread. feel free to ask questions if my instructions are inaccurate.
