Kill switch / Dead man question?

[RobWales]

All of the outboard powered boats I have owned in the past came with fitted as standard on the control box a kill switch and lanyard for your wrist! Obvious reasons I guess...small boat large wave thrown overboard etc etc

A bayliner 2556 F/B I owned also had one fitted and I guess I can see the reasoning for that also...

Now I cannot recall if the Bayliner 2858 F/B I owned also had one fitted as standard but the SS Portofino 34 I owned defo did not?

I'm wondering this as I do a lot of solo mobo'ing how big is too big for a kill switch / dead man and why hasn't my recent purchase FL Sprint got one fitted? (only 21ft and easy to be launched out of)...eeek

I mean I guess a lot of people do take to the sea's solo on occasion and if no kill switch fitted if the skipper collapses while going full chat it begs the question what next?

Does the panel think they should be a standard feature? just wondering!

having a kill switch on something large(ish) is pointless imho although I do understand the solo motoring issues.

So, how about a pulse receiver with a bluetooth transmitter on the sole occupant and a BT receiver module under the dash checking if skipper is still on board and heart ticking?

V, I'm working on that one..........

If you want some help,

arduino board circa 20euro
arduino BT module 60euro (one of the most expensive bits in the arduino range!)
breadboard, cables, ties, solder, etc a few euros
box maybe another couple...

Sourcing the chest strap with BT is going to be a bit more of an issue although there are a few ebay solutions that connect to your mobile phone.

Programming the board in C, or processing or whatever you wish not so much of a problem.

The idea being that one of the board outputs is fed to a largish relay that runs the kill switch for each engine.

I seriously think it's not that difficult and may have a point on 25+ft mobos.
No help on sails though unless the relay runs an automated system to roll up the sails or whatever you call the process of

10% Please....I thank you!

Rob, unless I get a 20% deposit from at least 100 ppl for the reasonable price of 1000euros a piece(*) it's a non-starter

soooo, don't hold your breath

(*) I hope you'll agree the price is reasonable, after all the hardware costs close to 150euro, programming will be another 150 and then you typically multiply by 3 for marine and mobo, possibly X4 for sail.

Hey! That's discrimination. We raggies are all impoverished enough already.

sorry you are right,

the sailboats that do have the electric winch to roll up the sails (probably not called winch but you get the point) are most likely much more expensive than the typical mobo that could have use for this system.
Hence, I'll change the factor to 6

Skint sailors wont use the engine so not much point to them

TTL Bluetooth modules compatible with the Arduino £15 or less.

So just after you fall out of your boat and it is coming back towards you at 30 Knots, you realise that you left that bit of test code in your Arduino that just flashes the LED rather than cutting the ignition.

I guess you're an experienced hacker then

Actually, yes it could be something like that, on my two last largish hack/progr/live projects (my Fiat coupe 16vt ECU tune and my house automation system) I did have such incidents...

Once I copied some values (nly by mistake I copied a lot of zeros! ) into the injection duration on the 3D map that relates it to revs and boost iirc and the result is that under v.special conditions of said revs and particular vacum I'd loose ALL power very violently! luckily after half an hour on the code i figured the error but I was 300km from home and eprom writer so had an interesting trip home for sure...

At home even last week one of the touch displays started beeping and wouldn't bl00dy stop unless I hit a few keys. That's definitely some "oh, I wonder whassat, let's put a beeping routine here and see what happens" that's left in there for the last 3-4 years And two weeks ago the living room shutters came down without anyone doing anything (that's going to be a hell of a job to find as code is rather large built over the last 5 years and tbh cannot be arsed....)

so, yes **** could happen
but don't worry I'll make sure I consult a lawyer before I sell any (more important than debuging the code these days, isn't it?)

Just giving the autopilot a new course to steer that's dead into the wind should do nicely. I've considered doing something along these lines myself, although not with the heart monitor

From the sound of it only a novice compared to you - I don't think I would be brave enough to connect an Arduino up to the cars engine managment system. Best I have managed in the car is using one to interface a Sony wired remote to a JVC head unit (A/D to serial data).

At least the Arduino is more robsut than any windows product and is an incredibly useful bit of kit.
