NRF24 receiver and brushed motors
Posted: 23 Jun 2020, 12:58
With the advent of 2.4 GHz DIY systems, see viewtopic.php?f=42&t=968 , I am considering the possibilities for its use. Flying models with it will be a bit of a concern in my country, for insurance reasons.
So I will install it in one of my RC sailing dinghies for sure. But I do have a Springer Tug boat fitted with a good old Mabuchi 540/550, and I would like to convert that too.
I know I could buy a forward/reverse ESC for brushed motors and simply plug it into one of the servo output ports, but it occurred to me that it could possibly be a bit simpler than that, as the ESC logic can be integrated in the Arduino, including the conversion from the received signal into true PWM, leaving just the power fets to add. At least that is my thinking, but I need an expert to confirm this, and hopefully come up with an appropriate schematic for the H-bridge and associated components.
Like Frank (tiptipflyer) I also have an original Tamiya Wild Willy sitting on a shelf, and I am also thinking of Gigafying that. Mind you, I could use the original servo operated resistor speed controller and reversal still fitted inside.......
Cheers,
Max.
Edit: having said that, HK is selling a 15A continuous for less that 7 euros (forward, brake, reverse, 2s max.), you can't beat that! I must confess I ordered some.......
But I still need something for my Tug...
