Any suggestions for a backup throttle for a VESC, which I could use if my remote fails out on the water? I’ll have a phone with me on the water, with vesc tool, which I could use to switch input methods. I usually travel about 1.5km off shore with my tow boogie for waves, and I prefer not to swim back if the remote fails. Commercial remotes such as maytech, erayfoil, eskate, are unreliable after a while.
I was thinking I could use an ADC input, and switch the input method with vesc tool while on the water if required.
I don’t think you can run two pwm inputs to the vesc.
My vesc only has a single uart, with Bluetooth dongle already connected for vesc tool.
The motor control feature in vesc tool doesn’t seem to work very well, and I’d rather have a button or trigger.
The uart is currently used by the Bluetooth vesc tool dongle. Can you have two remotes running simultaneously via uart and ppm? I figure I could switch the app in vesc tool from ppm and uart to ppm and adc if I have a remote failure.
Has anyone had two simultaneous control methods running with a vesc?
Soefoil, are you suggesting adc mode with your two magnetic leash position solution?
I’ve setup a reed switch window sensor via a voltage divider, set at 1.75v, into the ADC input on my VESC. I’ll mount it on the tow point, where I hold on to it when I need to tow while lying on my board (such as when rescuing a drowning swimmer). I can switch the vesc from ppm+uart to adc+uart with my phone if I have a remote failure. I can set it to a throttle level in vesc tool that allows for a slow but comfortable prone tow home.
The felix remote might be a tank, but I dropped my last erayfoil in the surf, and that could happen to any remote. The rest of my tow boogie is very reliable, it’s always been a remote issue that has caused a swim for me.
I tried that, but it wasn’t working for me when I tested the vesc tool motor control feature. Using the touch screen while in the water also isn’t practical for a 1.5km tow home. A reed switch on the tow point is much more usable.
Yes, using @jeffM solution with the pull-down 10k resistor. There must be some kind of protection above the kill switch boxes (a toggle slider + a red color code), so that in a stressful situation, one doesn’t confuse between remote and auto position.
In addition, the auto mode must be kill leash operated to stop even if used on a tow boogie.
Hi there you can just use a touch sensitive switch which is made from 316 stainless and 100% waterproof this will then run a circuit that produces a pwm signal that you can preprogram for power and time. When pushed it will run for a set time Just need 5v and wire it into the esc signal input. I make and sell a unit designed for surfboards if you want to buy one.
Works well with the window reed switch on the tow point. I have the magnet in the Velcroed on part, which I put in my thumb to hold over the reed switch while holding onto the tow point. With a ten second ramp in the vesc, and the throttle curve adjusted to allow a moderate amount of fixed throttle. I can switch from ppm+uart to adc+uart, and it gets me back to shore.
