I just wanted to share a video of my electric SUP build made using a couple T200s. They’re some amazing little motors and I’m super impressed with how much thrust they generate for such a small package.
Thanks. Unfortunately I don’t have much more than anecdotal data. It does get a bit warm in the enclosure, but I havent had any problems yet, even under the hot Texas sun with a black enclosure.
As for the speed, well its definitely faster than your average paddleboarder. I usually cruise around at about 50% throttle. If you’re not careful and go straight to full throttle you might lose your balance and fall off. I almost did my first try.
Unfortunately I am leaving on an extended business trip today so I won’t be able to get out and ride it for a while.
There are multiple switches, buttons, LEDs, and the main throttle is a potentiometer I believe. All are exposed to water ingress. Definitely a challenge. I think it would be easiest to do what some of the diy skateboard guys are doing and take an off the shelf rc controller and stuff it in a custom 3D printed shell. Maybe some sort of silicone sealant between the halves.
Not sure what sort of sensor you would use for the throttle. Maybe a magnetic encoder wired up as a potentiometer? I know Austria Microsystems used to make an encoder that could be used like that.
For my purposes I was just sticking it inside 2 layers of Ziploc bags and trying not to fall in, haha.
Zackary, I have 32 Ah battery packs. Usually during 3-4 hour fishing trip I never spent more than 40% capacity. At 1800 PWM (3/4 power) my speed is about 6 km/h (3.7 mph).
So, I’m very interested if you can measure speed at 1/2 and 3/4 power with one and two thrusters. If the difference is significant I may add second T200.
