Since we’re all still having troubles with all that wireless remotes and there are no actually good remotes on the market that just work for long time without electrical engineers fixing them from time to time, I thought about developing a cable remote with this community.
- No battery that need to be charged
- No fancy electronics to get water damaged
- DIY so everyone can built it with simple and cheap components
- No way to lose it since its tied by cabel
So how to do that? Here are my thoughts:
Princip: HALL sensor with magnet in housing. Connected by wire to ESC. Power for HALL sensor by ESC. Nothing else!
Top level requirements:
- corrosion resistant
- pull resistant
- easy to built
- no way to accidentally apply throttle ( 2-step activation?)
Sensing: HALL sensor paired with a magnet on a spring actuated lever (pistol trigger style) (maybe don’t use a steel spring du to corrosion and integrate spring into printed part)
Housing: FDM 3D Printed ABS ( no need for water tightness as sensor and cable will be soaked into water tight stuff like “PlastiDip” )
Cable: Repurpose any 1.5 to 2.0m USB cable (4 wires and often kevlar reinforced for pulling). Cut off small connector and solder onto hall sensor.
Connection to eFoil: just a hole with watertight seal OR watertight USB socket to unplug the Remote (sense?)
Connection to ESC: For VESC you can just hook it up as analoge input, for any PWM esc you need device to convert analoge to PWM (arduino, or a special IC?)
So, what do you think?
