RC Deck - Performance Power Supply With Radio Control

[FriedlS]

In order of waiting to further updates here, i created a simple version of a rc box:

 

 

Because of my BuWizz doesn’t work anymore, I decided to put some rc components inside instead of the original BuWizz components
Reciever is a Radiolink R4FGM

Battery is a small 350mAh 2s Lipo

ESC is a small 10A brushed version.

So everything is placed well and it fits very well in my cars 😊 

@NoEXIST are you still working at your rc deck?
@aFrInaTi0n have you already tested the rc decks? 
 

looking forward to some updates 😊

 

cheers, Friedl

Great entry @FriedlS, it is always great to see custom-builds like this. :D
I was afraid @NoEXIST not replying recently, especially during time when there were floods in Poland and Czech Republic - I hope you are alright.
Back to the build, I assume this custom RC board is suited mostly for smaller cars, that do not draw much current, and uses not so power-hungry motors, right? Have you tested it already? :D

[FriedlS]

@Krxlion you are right, this is only for small vehicles. I tested it with a buggy motor and a geek servo and it works very well. Of course the small battery doesn’t allow heavy models 😊

My two units are still in their boxes unfortunately @FriedlS - job and other topics are kind of overwhelming, I hope I will get more active soon again as I really miss the joy it brings.. so got a jumborc transmitter here already, just a thing of ordering a charger and some batts..

I like the direction, I have also been thinking of buying some chinese battery box (like this) and repopulating it with RC electronics inside. However, it would be great to go one step further in reducing the cabling, and to reuse some of those PF ports, charging port, and the turn on button already in the housing. Any ideas for how such things could be wired in? Unfortunately, I think in those chinese battery boxes, everything sits on a PCB that holds the motor controllers as well, that we'd like to replace..

[aFrInaTi0n]

I would think of a simple PCB holding the pins for the PF ports, a usb port and then just route it to some soldering holes for cables?! But I am not into PCB design.. so the PCB could replace the original and the cables could be soldered from the bottom to go into the free space of where the batt was / leave the housing.

Yeah, that was so far my best idea too, but I'm not into PCB design either.. Actually, I think space would be tight for cables as well, so I was wondering whether it would be possible to make it just using those needle-like thingies soldered to the PCB in the right places and then just connecting the different components (ESC and receiver) through those needles. I guess that would minimize space requirement and simplify assembly as well. Also, things like turn on button and status LED should be soldered to the PCB at the right place. But not sure if such a PCB can be made with an online PCB manufacturing service. Anybody with such experience / knowledge?

[aFrInaTi0n]

If you want to have them in the correct place and stay there, I would recommend another position to solder the cables.. otherwise it may really get nasty with the pins.. Also in a simple PCB design I think the thickness of routings in the pcb could be done narrow enough for limiting the connection point of the pins with the plugs..

Couldn't we ask @NoEXIST if he has a MK Box or so to open and design us a very simple pcb? 😅

I do have a buwizz so I can try to make a part that will help with transition between jst and PF connectors

Glad to hear people are still interested. I'm alright but I was kinda inactive with this project, I'm busy studying. 
 

However I do have some plans to try with new versions of RCDeck. Right now I'm waiting for another ESC option. Previous ones didn't fit requirements. 
 

@FriedlS Nice way to give your buwizz a new live:)
 

During this time I got some more CAD and 3D printing skills to improve quality:)

you could also use the PartsPack from Philo as he had designed the Buwizz 3 receivers - possibly then its a nobrainer to create them as regular 3d models.

You probably can try to print it right with those 3d models, however pcb designing is the whole other world where the most important would be dimensions and pin placement in general

Speaking about PCB design, I have been looking into just that recently, and I was wondering how you made the PF connection in your RC deck. I remember seeing an image somewhere in this thread about the 'pins' going from the PCB into the PF connector, but I can't find it any more. Can you show that part? Did you use some 'standard' electronic part like a pin / pin header, or was it some custom flat bent metal part?

That was very similar to a buwizz design. Standard pins were placed to touch PF connectors. I will be able to to show the part maybe tomorrow.

However I don't really think this is the best way of connection for increasing power. JST instead of PF would be all the way better:)

Sure, thanks, I'd appreciate that, standard pins sound simple enough as a start!

You mean ditching PF ports? Sure that would be the best but then standard PF motors are not compatible. For not too extreme power (up to 2 buggy motors / XL motors, and up to 4 L motors) this method should work fine though.

It has some advantages even with low power, but yeah the biggest point is that it won't be PF compatible anymore.
