Hi there, I wanted to show you my VESC NRF Hand Controller. It is based on Benjamin Vedders Nunchuk RF PCB and can be used with any VESC. In fact it is a NRF Nunchuk, put into a 3D printed case to get rid of this little thump stick and to convert it into a trigger.
All 3D data can be found here: http://www.thingiverse.com/thing:2027168
First of all a few pics to show you what I’m talking about:
Thanks go out to @chaka, who documented his Nunchuk RF build in this thread: http://www.electric-skateboard.builders/t/vesc-nunchuk-rf/588/30
So I ordered the PCBs at OshPark and assembled my NRF24 based Nunchuk RF.
This PCB is intended to be placed in a Wii Nunchuk.
On the VESC side the NRF24 transceiver can directly be connected to the VESC.
Luckily things worked from the start, there were some things that bothered me:
- connection with NRF was better than with the standard nunchuk but still not 100% reliable
- soldering required to change the NRF ID
- this fiddly thumb stick…
So I started upgrading it with an ‘Hex switch’ for the NRF ID:
A NRFL01PA ‘long range’ module for TX and RX:
And finally after a series of prototypes I put all of this into a nice case which converts the thump stick to a trigger:
