Idea for new MTB product. (Electronics project)

For my A-level (year before university for you americans ) Technology & Design project i am making an electronic device, which would potentially be used for Downhill mountain bike riders (or rally drivers for that matter) More likely to be of use to professionals, or extreme enthusiasts (the kind of bums who time their runs, you know who you are )

Specifically, its a device, like a pace note system, that will alert the user to upcoming major events (corners, jumps/drops, wet patches, rocks etc) It will be pre programmed, specific to whatever course needed, and will use a series of LED's each one corresponding to the event. It will be handlebar mounted, and will use a push to make switch to move the program through its sequence. (Pass a corner, hit the button and it will tell you whats next).

It will use a generic PIC (peripheral interface controller) circuit, and the program will be set on a pc (PIC logicator) and a 9v battery to power it.

Let me know of what you think about this idea, and any subsystems i could possibly implement into it to improve its usability. I know it isn't going to be 100% accurate, but hopefully give me enough marks to put me through uni!

Also totally forgot, i have a questionnaire that requires filling. You don't have to do be a DH rider, would give a nice spread to have riders from both sides really.


"1. What kind of riding do you do, and how often?



2. Have you ever raced, and if so did you learn the course before hand?



3. Would you benefit from a pace note system?



4. Have you used any similar systems in the past, if so what attracted you to use it?



5. What would be required of this system to make it efficient enough for use?



6. What would be the best interface for this system?



7. Where would you want the device to be mounted?



8. How much would you be willing to pay for this device?



Any other ideas:



Thank you so much for your time

It will be fairly feasible to implement with very little memory since you're only storing a negliable amount of information. For a high school project, your ideas are more than adaquate.

However, in the real world racing situations, riders will only foucs what's coming up, and will not take their hands off the handle bars to press a button, nor will they stare at the flashing LEDs to find out what's coming up next.... Especially in a downhill situation

Good luck

Yeah i thought about that, maybe giving audible beeps would improve the feasability, although it may be hard to hear, while trying to steer your steed as vertically as possible without getting intimate with any trees

Useless in my opinion.

Downhill courses are short and the major characteristics of which can be learned in a run or two of practice. For Rally, I could see it though.

...I don't know...for me it would take the fun away. Half the fun is the reaction or lack there of.

For sure for ralley racing

Cool idea for a project I think but commercially viable? I'd say maybe not...

This is the problem I see... double-press a button or miss a press and the system will be out-of-sync and get shut off because at speed you don't have time to divert concentration to fixing your unit.

WRC co-drivers can adapt to wrong notes, missed turns, minor accidents. An computer can't (easily, that is) What would be cool for DH racers is a video/audio link using a helmet cam. A coach could then give pace notes from a course location of his choice.

Sorry...I think this would work really well for training for sure. With video capture etc you could develop a decent system to help people find their mistakes in lines ...

who is nicky grist?

as an o-level subject, it's excellent. as a marketable product, someone out there's gonna buy into it, as a yuppie fad or something even if its not taken seriously by professional/experienced DH riders

yeah, now that Collin is out of a job, more or less... I know Citroen opted not to renew him for the season so he ended up not having a contract for this season. Kind of a shame that one of the legends of rally racing couldn't even find a team to take him on.

Why did no one take him on? I mean, was he winning, but still couldn't find any sponsors?

Sorry to push this thread further off topic.

It'd be way too hard to operate and you would need to program all the stuuff ont he trails. Plus, you could break it on a spill.

In reality most of the stuff could be automated with a combination gps / elevation map. Then have some basic object pictures variable sizing etc and you could pretty easily make it completely automated besides some very basic object placement.

The more I think about it the more it could work in train scenarios, to see where and why you do what you do.

Actualy it would be kind of useful, but not for racing or anything. Say you are taking a long trail, with lots of side routes and stuff. You ride the trail once, and hit a button every time you pass a landmark, place to turn, etc, and it records the distance (from a wheel sensor like a cyclometer). Then when you do the trail again you get a reminder when you need to turn and stuff.
