DIY Waterproof remote


Hi Clarin,
your post is one year old, is it still your interest to find a sensor for the height of the board relative to the water surface? I have an idea how one can solve this problem very smooth and cheap! I’m a beginner with efoil building, but as an electronic engineer I plan to integrate such a sensor in my efoil and let the controller board regulate the flying height.
Best regards,


@Skysurfer I am glad to see other EE engineers around. I have been working on a auto pilot kind of controller for efoil with resistive water depth sensor from adafruit. Eventually the goal is to have a controller can do cruise type of ride mode, throttle curve and lots of other stuff. It might be possible add some control surfaces on the wings for assisted ride


I just wanted to follow up and let you know this fixed ALL the problems with the remote. I removed the ACK and speed up to 2MBPS. Its unbelievable the change. The remote is super responsive now, great modulation and NO delays. Thank you so much for the tips!!


Are these available? I would like one and furthermore we can perhaps adapt this into a paddle shaft?!


Is this tube off the shelf? Or designed your self?

I want to show you my easy waterproof remote.

It’s the circuit from a maytech remote (from Alien power) slightly modyfied to fit inside a 100% 3d printed housing (petg / tpu) covered with epoxy.
It does not use a hall-sensor. Instead the throttle is mechanically connected with strong magnets to move the poti on the inside.


Great design. Looks good


Hi, I found a waterproof remote on Aliexpress and the first impression is good! Not the case is waterproof, but the electronic components inside. Nice idea I think. Up to now I have made no tests in the water. I will try later.


suggest you make more coating on the circuit board and the battery connection before salt water test
