Re: Suki ROV
Hey, yes! Look at RC car escs. I also was a lot into electric skateboards and they used VESCs with are really powerful and completely programmable. It seems weird you would brake your motor. Mostly probably you would brake the esc. You should create a protection circuit with diodes and capacitors. F...

Re: Suki ROV
Hi, great Project!! I don't think you can reverse polarity in all kinds of ESCs. If you want to use this ESCs, and be able to reverse them, I would suggest you tu plug a rele to two of the output cables on the esc so that when it is active it will switch both cables, this will make the motor go on t...

If you go to my amethyst AUV thread you will see I 3D printed almost everything. the 3D printed parts costed me around 40€. Also having some...

Re: FSK modulation to transmit further
Big plus for you is that in water sound travels further. Disadvantage of this system is that you only can do half duplex and think about both the land side and rov side sending information at the same time which generates more noise. It can also be Full duplex. I use one frequency for the controlle...

Re: U-DRONE Amethyst AUV Platform
Here's a little study I made for the "wireless" control of the ROV.
Any cheap suggestions for a Hydrophone or a speaker that works also underwater?
