Homebuilt ROVs Forum

Thanks for all reply ! Ok ,sensored can be a solution for hight efficient, and can be a solution . But I'couldnt think modify one esc soft or hard for a beginner like me . I read your post ,and effectualy after test a less Kv motor can be a solution ,but big motor ,need hight voltage for run ! i see...

Hi everybodys I think will employe brushless motor on my futur rov But in my some system test before ,see couldn't run under a minimal speed rpm with any esc controler . Do it possible run from null to few rpm speed with a brushless motor like 0 to 60 rpm in my exemple ... Or does are minimum speed ...

Hi everybodys ! Newbye in this system and very interest, I would like display multi analog input on my Videoscreen , and can custom it , like have pressure in bar ,temperature, current ,speed of three motor . I have no problem to convert their physical value on µcontroler card ,but don't know if can...

Here a very simplist sheme of the modification on the attached document ... Some people can say ,learning port work too in this configuration : Yes, allright ,but in power off configuration without the 2.4Ghz module ,and no backlight (if you have one like me ), and you can break the very thin coaxia...

hi Slimsy, In first ,did no explain good ,what i'was do . I realized a direct connection from my Transmitter (turnigy ) to my own built receptor just like this circuit attached in my post , don't use any commercial receptor, cause internal bus not ppm . In your transmitter from the main board (where...

Hi Slimsy ! Think answer to this post long time after ,but listen ... I wanted control a little rov with my Turnigy 9x too ,and with a simple ic and few componant (no programing needed) You can control about 9 chanel trought a bifilar tether connected on your radio. Using trainer port work good ,but...

OUps !

Excuse me, (the alea of my translation error !)

If I think good ,you ask me if your card work ?

I do my prototype on fly wire ,and work good ,and i think yours too.

Hi Fluxno ! Actually ,I built my card with my CAO soft . I built a pcb particular ,for some test , like : -acquiring in/out signal for my logic analyser with sub d port , -powering with a LT1084 (3A capability ) -external count for test It is few little modification ,not very important in the concep...

Thanks ! Fluxno ,actually can't test this modification ;
But in 2 day can, and change their value .

I just buyed my tether cable for send video and data like helmet audio speaker cable (two monoshielded wire #22)
This week I would build this decoder and would test it .

Thanks your help !

Hi fluxno! Thanks for your reply ! I knows the precedent ppm to pwm converter using 4017 chip and tried to used it on my transmiter ,but dont work or work no good . Cause I think my transmitter use 9 channel ,but today I 'am trying to have an emitter / receptor based on this application gived on thi...
