Freestyle kill switch....

D-Roc

I forgot!
i was talking to a buddies car tuner for his WRX and he is into making electronic differential control units for these cars. we talked about the proximity cordless kill switch. something that you could clip to your vest and it sends a signal every second or so to keep the motor running. once you get 10ft away it doesn't recieve the signal and shuts off, same as if the battery dies on the unit. it kills the ski. We have to go back up to his shop to pickup a wrx transmission and i will be interested to see if he made any progress on it or not. i wanted it to plug into the stock yamaha wiring and to be watertight. sounds like a good saftey product incase of a stuck throttle or whatever else could make a ski runaway.

I like that idea. really wouldn't be that hard. gona do some looking. my other idea was to use a linear actuator that would only activate after 3 or 4 second of a the pole being down. but i think your idea would be a better idea
 
I've been mulling it over for ages - tempted to look into it commercially last year (loads of uses like RIBs/power boats/ski's etc where you need to move about the boat but need the safety of a lanyard - just don't have the time anymore (new father) - be great if someone picks it up and makes a go of it!

Good post - I was thinking about this freestyle lanyard situation a while back - how hard would it be for someone to make a 'proximity lanyard'? - you could use the same technology as modern cars - i.e. with the card key in your pocket its live - move 8ft away from the boat and it cuts the ignition.. the tecnology to do this is in the automotive industry now (Renault cars use IIRC) - someone (good with electronics) just needs to apply it..

This would allow all the hood tricks/monket jumps etc with no restriction but offer all the safety of a lanyard system when the ski is 8ft away or further... I'd buy one for sure.. the peice of mind of not chewing up rocks on the bank or worse would be great.. Also imagine a situation of a jammed on throttle/ghost ride situation with a free style cable tie lanyard.. just imagine the insurance situation of bypassing a lanyard (which we all do..)

Thoughts?
Great idea,Also the cards could be coded so only the card holder could start your ski.Just a card and a receiver, exellent idea.Call the patent office.

Only one problem. your battery goes dead and your not going any where. but then again with my system if something goes wrong. wave and watch you ski run off with out you!
the only thing i'm thinking is a timer combo so that even if it does go hey wire it will shut off after a bit on its own
 
if your designing this for hood tricks i dont think the button under the handpole will work as most hood tricks are done with pole down, some people have pole springs or run tight pole bolts. but i like the idea of the remote thing

I have been trying to design a cordless kill switch for almost a year now. it is not as simple as it seems. There are many factors that come into play. i am waiting for the technogy to advance and i will have one where there will ne NO battery. Who wants their ski to die because of that battery? Those batteries wont last long anyways. and making it water tight wiht a battery is cool , but what about when you have to replace the battery?

As of now i have the means to design one with the battery. I just dont think it is economical/logical, therefore i am not waisting my time with it right now.
 
seems like i do less swimming without a lanyard. if you fall off and it dies, u have to swim in a straight line until the ski runs out of momentum. With no lanyard, you fall off and swim a few feet at most to intercept the ski circling back to you.

the company that my dad works at in order to get into the building he has to wave or hold this key near a pad, no battery on the remote key

Same technology that i am waiting for. it has to do with magnetic feilds. The problem is that they have to be within inches to work, we need somehting like 10 feet.

see thats what i mean! but HOW do you get the ski to come back! i know the old ones do but what about the newer ones? do you think a light spring would do the trick. ive been looking into use some electronics to pull a hard turn when im off the gas (a way to over come the hood tricks) and the pole is down for more then 5 seconds
 
mine seems to come back, but i have the idle pretty low and i ride in absolute flatwater, when i ride in rough water i turn the idle down enough so it stalls out.
definately would be a cool invention with tons uses if someone could develop some kind of technology.

Some of the new cars now days are using pass keys, which unlock the doors when you're close to the vehicle. They will also will adjust the mirrors positions, seats settings, steering wheel position, AC & heating controls and start the car with the push of a button. Most don't even have batteries inside the keys because they use a device called a triode coil which charges them when you're in the vehicle via radio frequency.

It would be nice to have a pass key setup for a jet-ski where the ski would come back and get you after falling off.

i originally thought a button on a keychain style that you press the button to kill the motor. there would be down sides to that as well so when they guy i talked to suggested a proximity switch it sounded better. Maybe a way to disable the prximity switch with the landyard clip??? That way one could override the proximity if the battery on the transmitter died. Its a great idea...someone needs to get it happening in a reasonable priced way.

I know we have had boats take off and try to go to Canada (probably for the better strip clubs). Both, :bigeyes:Superjets and SXR's. Don't trust that your boat will come back. It could also hit another boat, rocks, etc.

Most ski's will come back to you but once in a while it could go straight for a while .Just turn your idle down so it stalls without a rider .

This is the best way for surf riding because you don't have time when another wave is bearing down on you to look for a lanyard key and insert it into the switch .
You just get on it and hit start and go .:biggthumpup:

yea that wouldnt work for surf riding either...half the time you are doing a slash on a wave the pole is on the hood

The other problem would be when you get to the stiff pole stage (which we all do) - poles don't necessarily fall back down when you fall.

I love the idea of a proximity system though - someone make that work!! :biggthumpup:
