thanks

Just something to think about.

thanks

Some photos from mission our camera need to be improved :cry: http://s25.postimg.org/dqe735twv/3843_10203555582196041_169073294_n.jpg http://s25.postimg.org/mmoz73kj3/1924418_10203555583436072_1004176750_n.jpg http://s25.postimg.org/ksc4pcxin/1932463_10203555584636102_1983087030_n.jpg http://s25.pos...

Will you be posting more details of your design?
It would also be great to see some further underwater filming in the sea.
Well done and best wishes

Thank you very much.
I will post more details soon.
we hope to filming under water.

Thank you

@eng.hossam Suggested area to investigate further: A remaining question from a previous post by Rossrov is what type of motor are you using? Have you tried a completely different model of motor in your circuit? If your circuit is OK and your relay specification correct then I wondered whether the b...

it's 5 A and relay can handle to 60 A

rossrov wrote:OK, so what are the relay specifications? AC or DC coil, coil voltage. What voltage are you applying to the coil. Or is it the contacts that are burning?

yes,the contacts that are burning
