This is interesting, but needs some tweaking. In my understanding, it works the reverse way of what we need. It is designed for safety with big drones or RC airplanes, so you put a plug to secure the system (prevent the motor from starting accidentially). When ready to launch, you remove the plug and start the system.
I got a similar Vedder antispark for less than 30€ on esk8 forum, good quality mosfet (5 in parallel) and 100A Maxi Lama fuse, works fine but still the problem is that using it as safety switch when you fall, will kill the ESC very likely
The plate with painter tape goes glued under the battery box cover, the other on top. The movement is “driven by magnet”, very smooth and fast. There are two magnets into the red plastic, one at 12 the other at 6hours, when one get the REED, the other gets the magnet and keep the position
@MaB Have you tested the mosfet switch under load yet? I am keen to buy one of these for a safety disconnect, but wanted to see your results first. I.e can it handle switching off under full load without destroying anything?
tried with few amps, lights, no problem.
I don’t think it could be 100% safe, it doesn’t ensure a galvanic insulation, if it fails usually it become an open circuit but i see mosfet in short circuit very often… M doubt are not about that Vedder switch but the ESC which will get a huge back bomb by motor coils…
Nope. The second fuse was 90 and it never blown. But the pcb is not up to and the whole system gets soo hot to melt tin soldering. It worked well for long time but for some reason it’s no longer viable for me. Time after time you start pushing the limit further on e foil…speed is addicting and the trill quickly fades
