With this cable output direction you intend to surf only one side?
The other cable is a leash?
What about using one cable for electric and for the leash?
Even if leash is separate, it mast be shorter than the electric cable. Isn’t there a safety issue, wouldn’t you want a longer leash?
To build round shape (and maybe flexible) battery ?
Yes, when I prone foil I don’t switch stance, but I could run the cable straight down if I wanted to. I use one of the straps to hold the cable into that position out the side. The second cable is the leash, no stretch and it is shorter than the motor wire to prevent undue stress on the faux drive cable and electronics in case of a wipe out. I’d be open to ideas on integrating motor cable and leash, but this seems the safest to me. I have been thinking through a flexible battery pack, because I think it’s a great idea, but this works and I don’t feel the stiffness of the box on my back the way it rides on the waist belt.
Yes I do. I took quite a few crashes my first go with it and didn’t have any issues. I think for bigger waves I would want the motor wires to release and use a regular leash. That’s what I initially did with an MT60 connector and it worked good, but I love the @hangloose connector. I think his connector would work great as a quick release because the connection is nice and tight without screwing the nut on. I would probably just remove the nut or figure out a modification.
I would use my new plug for the auto release. However, in a round shape.
With the new plug you don’t need a flat gasket because the gold plugs seal all around.
Here is my setup, I’m on a backpack
For me, this subject is the last I struggled with on my build when big wipeouts occur. I had to design several iterations before the good one, until when ???
I tried 3 options :
-1) Only elec cable with solid attach with a thin rope on leash plug and belt . Broke the cable several times because the shear forces on the rope attached to the cable is too high during a fall
-2) Elec cable with 2 x 15cm bungees on each end. One board side and one belt side. After the max elongation of the bungees, it’s like a solid rope and I sadly snapped a leash plug.
-3) Last idea was to combine a real leash because it’s designed for this purpose and the cable, heavier but more nimble. It’s a bit hard to take in account the max elongation of the leash to leave spare cable length on each side.
My leash is normally attached to the board + my belt, my cable is taken with the leash inside a sheath attached on the elec cable only with cable ties. It allows the extension of the leash inside the sheath.
And I added the first solution to secure the cable on both ends also.
When I fall, the leash first do it’s job and reduce the force on the cable if it tensions. And the cable is solid secured on both sides. It’s good for the moment
I’ll study the configuration with a waterproofed plug which disconnects when a fall happens. Interesting, thanks.
Nice works guys. I was thinking to move the battery off the boards too.
The connectors are awesome. Just a question, seen that my knowledge about electricity rise zero: but if after a fall the connectors unplug, there is any risk for electric shock at the battery ?
For a system in a backpack - a cable control solution fits perfectly.
It seems that controlling the ESC is as simple as an Arduino PWM signal…
Adding a pressure sensor would enable use between teeth, with a tongue, or with fingers.
I consider implementing it.
What are your thoughts?
Why not run a coiled cable and leash through the centre? That way they have a similar stretch.
Or run a coiled power cable with a retractable leash through the centre.
If you used a disconnecting phase plug you may start popping ESC’s.
Hmm good point, can’t ever imagine falling and pulling cable connect powered up though…it’s always in the surf scenario when pod is out of the water and motor unpowered. Is quick disconnect and esc damage still an issue when esc is powered but there is no throttle?
This is exactly what I am doing this days, I felt guilty to leave my backpack foil assist taking the dust because I only use m’y tow since a year and I discovered Flow Custom V2 solution so I took the train
