View Full Version : Simple lap timer

I have nearly completed a prototype of a very simple lap-timer...and I need your help to workout some desirable features.

I don't really want to discuss the merits of automatic lap-timers and more complex solutions...this is purely a box with a display, and a button. All I want to do now is sort out the software/features for it.

I plan to chuck a unit or two at some racers to help them out in the VMCC this year, not looking at making stacks of cash eh?

Design Concept:
A simple box with an internal battery and one external switch. The racer/rider rides around a track, pushes a button on the handlebars (mounted somewhere convenient), the unit will display the elapsed time since you last pushed the button. Presumably you are going to select somewhere on the track that is not considered a busy section (front straight/pit straight). SO ideally its to give immediate feedback to how fast you're going while you're out there on the bike.

So this is the hardware design:

The unit will be quite small, probably not 100% waterproof, will have a 4 digit display that shows time down to 0.1s. The image below gives you an indication of the type of display (x4).
The box will mount in under your screen, and there will be a switch that remotely mounts near your 'trigger finger'. I was thinking that I want a fairly universal mount for the switch (see pic) and am considering using the brake/clutch lever and a hose-clip (see pic).
I think I'll have the unit run off a 9v battery...means we can move it around bikes without having to wire to bike batteries.
There will be a reset button on the case/unit itself...and an LED that shows you some sort of status about your lap (to be discussed).

Software:
This is how I see the product working at the moment. I'm kinda guessing what would be useful immediate feedback for the rider while trying to appreciate the amount of time you guys have etc.


When you roll out on the track your display will show [0:00.0] or something. On the start of your first proper lap you will push the lap button [LAP] at a certain point on the track. I think that you would have the display showing the time counting up (reassurance).
...as you cross your trigger point you push [LAP] again. The display will show you the time elapsed since you last pushed [LAP]. Maybe [1:18.4]?
The display will show [1:18.4] for most of the remaining lap. Now I think that as you approach [1:18.4] the display might count down to your fastest lap time so far (obv [1:18.4] at the moment). Depending on the circuit and trigger point, you might have enough time to do this.
If your new lap was faster than your fastest lap I think I will have a bright LED flashing on the unit under your screen (next to display).
Optional: I could have the new lap-time shown as a difference in time from your fastest lap ie [0:04.3] (flashing LED would indicate a negative difference).
Reset button would reset the stored 'fastest lap'.


So, what do you think? I don't want to know how many people are interested in having one (I have enough to make already), I'll have a stab at getting it right, then maybe offer them for sale. I can't add data-logging and laptop integration features etc...but I can do trick things with the existing hardware/design.

Appreciate any help. If I can make them real good, then some racers get some good units to use. Cheers!

Sounds spot on to me bro. The counting down as you aproach your previous time would distract me, and probably have me hitting the button a bit soon, but the rest sounds good.

As for the button, it might be easier to use the horn button, just take the wires off the horn, and plug your gizmo into them. Although, that would try and feed 12 volts back through the timer, so maybe not such a great idea without a relay of some discription.

Shaun, I'd be keen to help you with this. I wouldnt worry about the countdown, you cant watch it anyway. if when you push LAP it displays the lap time for say...20-30s?? then counts you through the rest of your lap? can you rig trigger up to horn button? LED to signify fastest is good idea.
If your keen to work through it with me i should have a bike thru winter series you can use with me on it to work with??? PM me if ya want :D

10th April 2007, 19:50
Like the distraction point. Valid I think. I want it to be a case of clipping a couple of cable-ties and you can move it to another bike in under 3mins...the horn could be done, but would rather a universal/non-modification solution.

Piss off young fella, your lap times are an embarrasment to the rest of us already! He can mount it on my bike, because...well...COS I FUCKIN WANT IT!!!

Jay: I guess on a bike like yours the horn switch wouldn't be a problem. The horn switch would be wired up similar to how my switch would be anyway.

Let me get this done and I'll throw one at you too. Maybe put one on ya road bike some weekend. Cool?

I've never seen a horn with anything other than a pair of flat female spade conectors, but mounting a button would be ok. Problem with it could be, that the switch gear would need to be removed to put it the right spot, so more work for those of us using our road bikes. Sod all maybe, but I am a lazy bastard.

Was thinking that someone who thinks they're 'fast' in F1 can 'share' a unit with someone doing the hard graft in F3 ;)...if the swap over is SUPER easy, then it shouldn't be too much of an issue eh?

Take my name off the want list for the first one, I'm no good at sharing toys.

Two buttons then, one for each bike, that way there is no mount to remove.

Yea sounds good. we will have to set up a road 'lap' then :D
but the WarPig...you havn't seen that......:S
IF you want to work on it at the track, I should have at least one 600 at the winter series rounds. can work on positioning of the button for the easy on and of if you want. then me n fizzer can compare lap times...:D
Sounds like an AWESOME idea....

skelstar
10th April 2007, 20:03
Nah, I've seen the 'pig at the sprints.

I'll get a switch and make a little mini bracket that will clamp to a brake lever. I can test that on my hack...but I have to sort the software out first.

Dunno what the hell Cheezle McJay and Fizzybum are talking about.

A nine volt battery wont last long enough for either of those poofs to actually complete a whole lap.

Yours will be LAP times, they will compare to my CRAP times, so I dont like this Idea too much.

JayRacer37
10th April 2007, 20:05
Yeah, maybe an inline headphone connector or something? Hmm..

Even just put a wire on to the back of the horn button and remove from 12V system, then put a quck snap line break in, then the same on your buttons and then on whatever other bikes and buttons it could be going on...that way on and off easy, but still hard mounted to each bike...
How will you affix LCD display, and LED best lap light?

Will be in a little plastic box. Might have strategically placed holes for cable-ties. Maybe a clear plastic box so I dont have to cut holes for displays to show through.

That sounds waterproof in itself. It's not like they're going on jetskis.

Although, don't mount it too close to Ducati exhausts......

Yeah, the boxes I've looked at so far have been IP rated. Besides the guys I'll be flicking them too probably don't ride in the wet anyway.

Not sure they'll be IP rated for ammonia anyway...

semi-off tangent.... MotoGP 2003 (game) has a blue helmet for improved section, red for slower, grey for close to... why not have a green light to say you did better, red to say you did worse.

i'd be keen for one.

Flashing led on box would indicate fastest lap. Solid indicates slower.

10th April 2007, 20:22
What about:
You cross your 'line' display chsows lap-time for 10secs, then shows the difference between your last lap time and fastest lap time for the remainder of the lap?

Drew
10th April 2007, 20:23
Back on topic now, so long as the button isn't gonna get nudged unintentionally, and is easy to push when required, whatever is easiest to build would do nicely.

BTW, if Flame post in here, tell her to piss off, she's already got a lap gadget on her bike, although, it's beyond comprehension as to how the bloody thing works.

If it shows lap time for 10s, then goes to just counting up, you can use that to get a reference. say coming out of the harpin i was 24s into one lap then the next im 25s in..i know to come inot the pits cause ive blown the lap.

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.

R6_kid
10th April 2007, 20:27
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.

skelstar
10th April 2007, 20:29

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?

10th April 2007, 20:29
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.

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.

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.

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

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.

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.

Yeah, just like the 'no button' idea. I'm sure that a racer is going to be 0.2s out with their button-push too...

Seems you can get a bicycle computer for about $20 online.

Well...its a prob with the chip I'm using. Its a PSoc device, friggin quick to program and fiddle with. Otherwise it would be a PIC. I don't really want to stuff around with a non-simple-as UI anyway. Buttons everywhere..."which lap am I looking at?". Besides you can get printouts after you race from the officials if you're running with a transponder.

id b right with th button
i know i can be tottaly accurate. and i wouldnt want to have the magnet and speedo and stuff on the race bike
is the $20 unit guna be able to read at 280km/h??
honsestly, i can be as accurate all but on a stopwatch compared to tracktiming, from next to the track, riding over the same point lap after lap on the bike, runnning over a line or whatever and hitting the button on that mark isn't going to pose a problem.

Fair enough. Was wondering about fixing the speedo stuff on it too...didn't think about the max-speed issue, but Im sure that people use them as speedos for WOF time.

From my understanding, most trackday organizers nowadays are reluctant to run any timing device since it invalidates insurance covers.

I'm sure a lot of people would be interested in your lap timer device if it has memory.

Just wire the button as a clock that pushes the record into the memory/register.

The complicated thing would be to figure out how to retrieve the data, but this would be something simple enough to be talked over a beer night in the pub.

I like it. Would prefer the button to be on the left handlebar, cause the left thumb ain't doing anything else down the straights.

I wouldn't worry about the countdown as you get close to your previous best time, or showing the difference between the previous and last lap times.

Simply show the lap time for 10 seconds or so, then start counting up until you hit the button again.

Hmmm...I'm sure if you were racing a Suzuki your left-hand will be busy down the straights...

Yeah, but it dont take sod all to confuse you Kapati lads, the rest of us who have time to contemplate the meaning of life during a lap, should have no hassles at all.

I'm trying a new tactic here, get a dig into someone else, then steel any thunder thier retort might have, by paying myself out aswell:yes:

Hmmm...the display is kinda small Jay. The viewable area is 64mm x 16mm, thats 16 chars x 2 lines. Hmmm...got some trick info on the two lines though...Last_Lap, Fastest_Lap and a split time (next to fastest lap). The demo/prototype unit has a display that measures much bigger (99mm wide viewing area). The display of that size that I can get is quite cheap ($11), but is only one line. Not sure thats too much of a problem. Might just have to rotate the info around a little.

So...can you guys handle having a box that measures about 125mm x 50mm big in your top-yoke area (ooer)?

You guys think a buzzer that goes off about 3 secs before your fastest lap is useful as a reminder? Maybe I'll make the 'Fastest Lap' LED a big bright fucker, and have that flashing 5 secs before the fastest lap...

Ummm...how will it know 3 seconds before you do your fastest lap?

Can you bring along some demos Tuesday?

The buzzer would be drowned out by engine noise methinks. And loud enough to be heard over it would be a touch scary for the first few times it went off.

Mind you, my times have got enough room for improvement, that I could put off hearing it for five laps, had I the skill of course, so a slightly mute point:bye:

Dunno if I'd get time to hit the button twice during one wheelie, it'd have to be one of those super elite Scared sheep squadron types for that.

Displays too small, won't give you time differentials etc.

You can get them with a remote switch already, but when did you last see a cheap stopwatch, and would it stand up to a rough track. Or tyre wall breaking assister for that matter.
