    It can sing and dance as much as it wants
    as long as it's affordable!

    Lights a bitch unless its from above as other riders could block your signal, and if its above you needs a wide beam to cover the track.

    Could you not just have an emitter of some sort, FM radio sort of thing on the bike, then a data logger on the side of the track logging the signal strength as it should come through strongest only once a lap?!

    You can connect a wire to a sparkplug lead to give you rpm, stores 100 laps, has 5 engine hour metres, you can add a joiner to your water hose to give you water temp and at tracks like manfield with 3 strips you can do split timing. Think it's about $600 and can get it from Kart shops. Real good investment coz you can tell yourself to get your A into G if you're doing shit times.
    Magnetic would be good.

    Ah jeeze! I was getting all excited till RR came along a year later... wasn't paying attention to the date before that. Interesting to note how, in true KB fashion, skelstar offered something cheap and cheerful, and we all upped the ante untill it became too hard to make, too expensive to buy, and we all lost intrest.

    while it'd be cool to have something automatic and accurate, theres probably a very good reason why they cost so much. Dunno what the Norf Island tracks are like, but 'puna and levels both have slowish sections where punching a button slightly before or after your marker would make stuff all difference to lap times.

    I currently have no idea what my lap times are... except that they're bloody slow (hence I don't want to know :0 ). I'm at a point now where it would be useful to see how the lap times are progressing. so whos gonna make me a lap timer??

    Start finish line Manfeild, S/F line Taupo (if youre not trying to wheelie), Puke?

    Its a no brainer.

    The truth is I design electronic shit like this for a living. I have a few of my own projects Id like to do (heated handgrip controller for a start)...but can't even be arsed doing that either.

    Maybe when it gets colder.

    Done one of dem....you want the design to play with?
    What breed of engineer are ya Sklestar? i.e. power? (me) RF? embedded?

    Electronics. Some embedded stuff...very low signal stuff. Do some PCB CAD as well. Build intrumentation for scientists. +/-2kV PSU recently. Jack of all trades I guess.

    skelstar - If your really keen on this i am on my way to building the backend, my problem is figuing out the electric side(know enought to get myself in trouble, but not out again).

    I am having to do a project to finsh my degree, and rather write some software for someone else i have no interest in, i was planning on doing something that interest me.

    Software i am looking at, will have all nz tracks in them, and means you can store all your laps, and record other data that you would need (weather, tire information, all the nine yards)

    To be honest, esp since its summer, I really dont have the time.

    Initially (I think its this in thread) I was just gonig to have a box with a display of some sort and a button that you would press each lap. You'd cross a known point in the track and push the button. You'd look down and it would show the elapsed time since the last button push. Simple.

    No offence Cajun but the software wouldn't be the time consuming aspect of the project (pun unintentional). We have these wicked little devices by Cypress called pSoc Express which have GUI software language. Lots of fun.

    I could whip a schematic for the design, I *could* even do the layout and maybe make a prototype board, but even that wouldn't be the most time consuming part. I don't know. I'm willing to help someone else do it I suppose.

    Thats fine, I wasn't expecting you to jump to my peck and call.
    Was just bringing the topic up again to get people thinking about it and see 'Who' can do something for us over the next few months.

    Allun has indicated an interest in possibly building something (will PM you soon). If he can work something out, asking you other knowledgeable types question along the way when needed, hopefully something will happen.

    I will PM a few racers to make a list of who's in with some money.

    Anyone else who knows what their talking about chip in with comments, and lets make it happen! (Cheaply remember)

    That's all I need if someone who has the skills is keen...
