Simple lap timer

[R6_kid:Me]

hmmm... this would make it a bit less simple, but if you could setup one of those push bike speedo things on to it to measure the distance, you setup track distance as one push of button to next push at the start of your session. this way it is within 10m or so of the actual distance. From then on computer tells you how long it takes you to cover that distance... no pushing buttons til you want it to stop.

If it shows lap time for 10s, then goes to just counting up...

Yeah thats quite doable. I wonder if you can watch the time as you come to/cross your trigger point, would you forget to pull the trigger? You can already see your time after all?

A display of the last completed lap for twenty seconds is all it needs. The pilot will quickly know if was good, bad, or indifferent.

What about you have to hold the switch in for 1-2secs? Would trigger on you pushing it in (not releasing), and means you can abort the triggering if you fucked up or bumped it.

Would be getting a long time to think about it.....maybe half a sec
i would want it on horn. much easier to get thumb that top finger in full tuck.

Not too good methinks, given different lines, due to overtaking or cock ups, the distance could be quite a long way off. And at the track, fast guys work in tenths of a second, so it would be quite inacurate.

Thats a pretty damn good idea G. Will have to think about that...

U'd remember to hit the button to start the next one...
and if it displays for 10ish sec u can button it without watching just it, say if your in a group, then look when its safe to.

I thought a lap timer would just be a countdown for the number of songs you paid for???

I know four or five isn't many, but it's easy to lose count!

[skelstar]

Well...someone give me distance/laptime stats for a track? 1:18 on puke for what distance?

yea if you could make it no push too......

You racing this year Dafe?

uhh...3.3ish KM for manfeild, with a 1.09.2 lap.

Shit do I have to do maths now?

3300kms with a 10m difference is 0.3% difference. Thats a 0.2sec error.

Someone check for me please?

I'm wondering if a bike computer hall effect thingy would make much more expensive?

Honestly, a .5s hold push on a horn button timed from the first touch on that button would be quite managable.

I can't add data-logging and laptop integration features etc...but I can do trick things with the existing hardware/design.

Just add a volatile memory unit, such as push/pop registers with capacity for 30 laps that can be displayed as long as the power is still on.

I'm sure this concept is not too hard to implement.
