Vedder's Nunchuk RF

Post by chaka » Dec 02 2015 10:40am

We have some Nunchuck-RF PCB's in fabrication, should have them a week from now. I'll do my best to document everything during assembly and create a build guide. The Nunchuck has a 2 layer PCB and is a fairly simple build, a good project for someone new to smd with intermediate soldering skills.

The Nunchuk RF is a great piece of hardware, it provides a great platform for customizing the VESC with user programming, adding extra features to our builds.

Hardware: https://github.com/vedderb/nunchuk_rf_hw

Firmware: https://github.com/vedderb/nunchuk_mod

Don't forget to send a little support to Ben for sharing this great project! http://vedder.se/2015/08/vesc-writing-c ... /#more-916

You don't need this but this is a custom PCB for a Wii Nunchuck hack which you can use with the VESC.

is this to hack a normal wired nunchuku into wireless?
sorry if it's a stupid question.

Yes it is, I will have a little tutorial on the build here soon!

can it connect to 2 receivers? using one joystick to control 2 skates? like 1tx-2rx connection?

Im trying to build a handheld controller for my electric inline skates and I need one joystick to control both feet together.

would be possible to add this feature? :oops:

It is possible with spread spectrum transmitters/receivers but I would have to do some research to find your answer specifically as it relates to the nrf24l01.

as far as I know the nRF24L01 cannot connect to multiple receivers, but it can connect to multiple (6 i think) transmitters.

That should be possible with some minor modifications to the code.

Does this use the original Kama receiver to interface with the VESC?

No, it uses the widely available nrf24l01

Ah, cool. I guess that's app_nrf in the bldc code.

Wonder if I can fit one of these in the wired version of the Kama I bought by accident :)

Most people will/can retro fit a wired nunchuck with this PCB. Nyko Kama's and other wireless Wii Nunchucks will be sold out soon since they aren't in production as much as before.

We have a few more PCB's coming from OshPark. Will likely continue doing small runs while this is in development.

Just make sure the you use the latest firmware as it is unstable and can be unsafe, and don't have any of the 2k resistors installed to set the address to 0, then very soon I'll push a git hub update to the code that will search and set the address according to what you have set your vesc address to, this way you can have 2 ppl riding at once with out soldering resistors.

Just to clarify - are you suggesting we should or should not use the latest firmware?

as recommended by Jacob, get the latest version; I will keep you posted once I get one in my hands for testing.

Hi Chaka,

I ordered the PCB from OshPark (thanks for providing the files) and currently I'm soldering the parts on it. Have you made any progress regarding a tutorial to get started? I would appreciate any help to get the RF connected to the VESC.

Blasto has been making some headway on a tutorial over on vedders website. We'll push that info over here too. http://vedder.se/forums/viewtopic.php?f=15&t=75
