Cheap lap counter ?

[jonaswal]

I saw two different personal lap counting systems recently @ the BCA, but forgot to ask to the owners about them.

Do you know any reliable, not too expensive product ?

Thanks !

that also works with a pink no-windows body!

Most of them use infrared i think, so the transponder needs visual contact with the receiver. But you can always put it outside the body..

I don't know any specific products though

a friend of mine recently bought the DirtChampDesign infrared system.

It works with a wireless decoder on a little tripod, not always easy to put it on a 'safe place' at the track, for instance, you can put it under the wall, at BCA, so the 1/8th guys don't wreck it

Here's some info on an another infrared system fromRobitronic

There's also a system that works with the regular AMB transponder, but I think it's a more specific system for a MiniZ track
ILap timing systems

You can also share the costs with some of your racing friends !

Just give a stopwatch to Martin ?

The I Laps system does not work with AMB transponders.

it's safer to make a little hole in your side windows, and tape or screw it in from the inside though !

And for the pink windows, use a wide black marker and do like those guys did in there heydays :-)

The dirtchampdesign looks great !!

They say 4-7m, which is really better than the robitronic, which says 1,5m max...

Martin, you pay half ?

[mart3pop]

the price is a bit steep !

i want to try that idea i have first (building a foot trigger for my 3VC's chrono system)

Being a bit of a timing geek I found there's a stopwatch app for android (and probably for iphone) called Ultrachron Lite which will speak lap times to you and which you can start/stop/lap using the volume rocker switch on the side of the phone - so then all you need is some sort of way to attach to the back of your tranny (elastic bands), stick an earpiece in and then lap away...

I modified a cheapo case for the phone to have a couple of 'buttons' over the rocker so they are easier to press

I would only use it during testing/practice personally as it still means you need to press a button as the car passes you, and as my driving is bad enough I don't need any additional distractions during a race, but it's a low cost way of seeing lap times - provided you have the hardware of course...
