VESC FAQ | Connect The Nyko Kama wireless wii NunChuck

I’m with you on that one. so comfortable and easy. I’m Always on cruise control.

@lowGuido do you use the Z-button reverse feature? When I bench test it, if I’m holding full-throttle and tap the Z button, it instantly activates the brake and flips to reverse. In practice, does it automatically slow down the rider if that happens? Or, does, uh, just say “eff physics let’s reverse!”

My Z button is programmed for “boost” mode. I have no reverse so I cant really answer. I don’t really like the Idea of reverse.

Oh my bad @lowGuido ; I should have mentioned that I’m referring to the nunchuck\VESC paring. I’m guessing you’re using the wiiceiver? My question belongs in a VESC thread somewhere :smile:

your question is in the right spot. this is a VESC/nunchuck thread.

I use it frequently and it activates only after you came to a standstill. The VESC is not breaking unless you’re doing it yourself. It’s just going into neutral position.

It’s a useful feature for example when you want to step back a little bit when crossing a street and you are waiting for traffic to disappear. Or irritating other people. :smile:

Thx @elkick that’s exactly what I was wondering!

@joren check out the information above with regards to the nunchuck dongle. I suggest that you do something similar with your wiiceiver soldering the receiver direct to the PCB for optimal reliability.

Is anyone able to show how to wire the wii receiver to a duel VESC setup?

Not sure how useful this is, but I found this thing which I believe can connect into the receiver and expose the pinouts so that you don’t have to dismantle the receiver: https://www.sparkfun.com/products/9281

You still have the solder the connections, but it makes it more modular and if you ever need to replace the transmitter/receiver you can just plug it in instead of unsoldering and resoldering.

Even better, couldnt the VESC be redesigned to just take the receiver as a slide on connection? Do away with all the need for wiring, solder connections etc…

That thought has crossed my mind as well. Having a built in connector like the wiiceiver would be a good idea for those wanting to retain the integrity of their wireless nunchuck receivers. Couldn’t someone just modify his pcb design since it’s all open source? I wouldn’t be surprised if it’s been done already.

this is a bad idea guys. it sounds nice, but the socket will introduce a lot of dropouts and general problems. myself, and almost all of my friends have slammed because of a slide on wiiceiver socket.

solder on and save lives.

I have heard about the intermittent issues of the wiiceiver. So are those issues actually due to the wii socket itself losing connection temporarily or is it due to something in the wiiceiver pcb ?

Also does anyone have a guide to dismantle the receiver? Do you just break the plastic ?

Yes.

dismantling the dongle is easy… they literally just pull apart… no tools required.

Ah I see. I tried pulling it apart last night but I couldn’t do it. Maybe I need to pull harder.

there is a ring over the top of the plug that just slides off and the the 2 halves split apart. just apply brute force…

Yep. You just need to slip the ring off, then slide your nail into the crack and then lever them apart. Nothing more. DON’T go in deep with a knife as the contents inside are all a bit weak and flimsy and could easily be damaged.

Gently does it! Good luck!

I ended up prying it apart by using a string in the crack and then wrapping it around my hand and pulling it apart.
