I’m researching BR system and have some confusion in regards to their setup vs yours, BR says you can’t use a uni-directional esc with the thruster commander must be bi- directional. But you don’t have the thruster commander just esc with potentiometer knob and a reverse switch? How’s the potentiometer wire in to the esc?
Yeah, the reverse switch just reverses the polarity of two of the wires to each motor. The potentiometer is part of the servo tester, which is what gives the ESC the signal for 0 to max throttle.
Hello, I was wondering exactly how you setup the configuration for the system, im a college student currently doing a project similar and was trying to understand how you connected everything such as the escs to the thrusters as well as any arduino code that has been used, im currently having an issue with those
Hi, sorry about the delay in replying. I didn't get any notification of your comment. I just connected the speed controls to servo testers. I didn't use anything fancy at all.
Very cool!! Do you have any idea how much extra thrust you're getting in this config? I believe each T200 is rated at ~11lb thrust normally. Also, how much faster was your kayak moving w/ this as opposed to the single thruster from the last video? Have you noticed any problems (excessive heating anywhere) using 24V as opposed to the recommended 20V max? I'm working on a DIY sea-scooter and am wondering if 2 of these powered up would do the trick.
It's difficult to say how fast you might be able to go, but what I can say is that with two thrusters on the paddle, it's difficult to hold. At the power levels I'm running them at, I would imagine that it should propel you at much higher than 2 mph but I can't say for sure.
I just ran two of these at 20V on an 8-person raft with just me on it, and it went about 2-3 mph using a GPS app on my phone. I think you would go very fast on a paddle board if it's anything like a kayak.
Im gonna project this thruster as a pool vacuum. Would you be kind enough to help me wire my project? What type of battery should i use and what type of power wire that will work underwater? Thank you for your help
I can try to help you, but there are so many factors to consider. Do they not make a device that serves that purpose already? How long do you need the vacuum to function per charge? You would probably want to run it at a lower voltage (maybe 12V) to extend the life of the thruster. Can you run it from a GFCI-protected, corded power source? That will save you the cost of batteries. If you must use batteries, what's your budget for batteries? Any wire should work under water. You could consider using waterproof wire nuts, or if you know how to solder, you can use hot glue and heat shrink tubing. The servo tester isn't waterproof, so it would need to remain dry. The speed control should remain dry as well. I recommend posting about this at endlessphere. You'll get more opinions, and possibly better advice. endless-sphere.com/forums/viewforum.php?f=39&sid=56bb39b8fbc5d09929ccb41ae4ab0a26
Just Enjoying Life they do make already make pool vacuums but its the same concept if i make my own. I need the battery to last me 2-3 hours for the day, 15mins max for 1 pool and on to the next route. I was looking at a portable battery like a motorcycle battery or even better a bottle battery if it will last the whole day. ESC and servo will be dry and out of the pool connected near the battery. Please let me know if that would work.
Just Enjoying Life i have a blue robatic esc and i want to know how do i wire it to the servo? Is there a direct plug in ? Or do i have to purchase a connector adapter ? Thank you for your help
I can't help you with the ESC because I'm not familiar with them. I think it takes the signal from the receiver of an RC system. You could try to connect it to a servo tester, but I don't know what will happen since that ESC has reverse. It could be that the middle setting of the tester would be stop but the only way to find out is to try it. For a battery, I would look at 12 or 24V lithium ion batteries. You won't really know what capacity you need until you try it out in real life. You might even consider 18-20V power tool batteries for convenience. Would you have time to charge the battery between pools? If you get multiple batteries, you can just get enough until you have enough capacity for the job. If we knew how many watts you wanted to run the thruster at, we could make a rough estimate on how big of a battery you'll need. For example, mine ran at 693 watts. I had two 36V 9Ah bottle batteries. 2 x 36 x 9 = 648 Wh. That equates to just under an hour of run time at full power. Maybe you could run some tests with a power supply to see how much power you'll need.
ive done 'tank steering' on a model with a pair of smaller T100 thrusters.. it works well just using the mixing functions on a pretty basic radio transmitter . no extra equipment required. it does mean that you cant have full thrust in a turn though.
The cost of 2 thrusters, paddle, voltage converters, speed controls, servo tester, cutting board, wire nuts, 25 foot 12 gauge extension cord, project box, switch, etc. I never added it up =)
Can you please give me all the items you used? I’m trying to build a adaptable kayak using this system. I’m in a wheelchair and unable to use a paddle. I’ll be attaching the BlueRobotics thrusters under the rear of the kayak and was wondering what batteries and other equipment you used. Thanks man
I used a servo tester similar to this one smile.amazon.com/YoungRC-Consistency-Controler-Checker-Helicopter/dp/B076GMZW73 and this speed control www.ebay.com/itm/Hobbywing-SkyWalker-60A-Brushless-ESC-Speed-Controller-with-UBEC/262433262693 I only used 36V batteries because I had several laying around from my ebike projects. If you use a 6s 18650 pack (6 cells in series for 22.2v - will probably have to be custom made), you wouldn't have to use voltage converters like I did. I chose 6s because that's what the speed control could handle. Oh, and you're probably going to want to come up with a way to make it all waterproof. Honestly though, I don't even know if using a servo tester is the best way to do this. You might want to check out the Blue Robotics forum to get ideas. There are probably others that have done what you want to do. For more battery-related info, I recommend endless-sphere.com/forums/ but I can try to answer any questions you might have.
hi dude your speed controllers should be water cooled with a two small water pumps to the speed controllers and pumps out side the of the boat dude window wiper water pumps ,,,,,will do the job ....and a ,,,,,PWM SPEED CONTROLLER ,,,,, will save power to go longer
Makes for a good whisk as well!
Why don't you throw the paddle in water instead of bucket then turn on the thruster ?

How many volts did you shed at most?
I don't recommend going over 5 cells (4.2V x 5 = 21V). I burned them out running with 6 cells.
Very cool!!

Matt Secondary me too
Im working on A sea scooter too
How much did you tested it in sea water? I wonder what is the life of T200 in sea water.
I have not tested it in seawater.
I have been researching these thruster to use on my paddle board how fast will it get you up to?
I want to do trolling around 2 mph.

would love to see a video of this in use
How did you run the servo tester knob through the box? Did you have to extend it somehow? Is it waterproof? thanks!
I just drilled a hole in the project box and the shaft was long enough to go through. It's not waterproof.

Nice bro! Love it! I'm trying to make one but how much voltage and watts could you overvolt 1 thruster without it overheating.
I haven't tried it higher than 24V. Here's when I had one thruster. ruclips.net/video/AzO50rwD9NQ/видео.html
Please put in the components in the description
Build an RC recovery ring using similar thrusters, how does the streering work? Will just a rudder between the two thrusters work?
I have no idea, sorry :) I imagine you could turn on the thrusters independently to steer it.
ive done 'tank steering' on a model with a pair of smaller T100 thrusters.. it works well just using the mixing functions on a pretty basic radio transmitter . no extra equipment required. it does mean that you cant have full thrust in a turn though.
So what’s the max speeds you reach with them.
I'm not sure. Next time I try this, I'll try to start the Strava app.
how much price
Put it on a Kayak ;)
so great video... but what did all that cost you?
The cost of 2 thrusters, paddle, voltage converters, speed controls, servo tester, cutting board, wire nuts, 25 foot 12 gauge extension cord, project box, switch, etc. I never added it up =)
I provided links to all the main components that I used in my first thruster video ruclips.net/video/AzO50rwD9NQ/видео.html
2 motors is 400 usd and all can be 1000 usd
Where did you purchase your 12awg cables

hi dude your speed controllers should be water cooled with a two small water pumps to the speed controllers and pumps out side the of the boat dude window wiper water pumps ,,,,,will do the job ....and a ,,,,,PWM SPEED CONTROLLER ,,,,, will save power to go longer
Are all brushless motor controllers PWM?
YEP BUT YOU STILL NEED YOUR ESC BLACK AND RED GO TO THE ,,PWM ,,AND THE BATTERY GO'S TO THE OTHER SIDE OV THE ,,,PWM ,,,,CONTROLLER
Hi how much did you pay for each thruster
The price has gone up $10 since I bought them. bluerobotics.com/store/thrusters/t100-t200-thrusters/t200-thruster/
Another $1000 food processor
Were buy It ??
bluerobotics.com/store/thrusters/t200-thruster/
Most of the watts are wasted as heat and turbulence.
bonjour,
c'est génial.les boites pour les batteries tu les trouve ou?
denys
Hi! I still need to find boxes for the batteries because they are still getting wet in plastic bags. I might get a Pelican case.
Two thrusters didn't make you go faster, just ability to push more weight? Probably only need one for pushing 1 person.
Each thruster provides a certain amount of thrust. Two thrusters would provide double the force, making you go about twice as fast.
