Wireless Wii Nunchuck *TESTERS WANTED

I'm not sure which version of the code I've got, but it accelerates too fast for me. I'm assuming yesterday I was able to get up to speed because the board was running on fumes. The board definitely has more power which is awesome, but scary. lol. Is the newer code more incremental?
In regards to using a joystick: It's not hard to adapt to using it at all. The nunchuck was made to fit perfectly in a human hand and this is a perfect application for it. I'm very curious to try it with the throttle/brake inverted though - down for throttle/up for brake.

Mine accelerates way too fast, but I have low gearing on dual 8S ... try holding C and accelerate in cruise control? That's better for me. When things settle down I may screw with my own settings more, but for now I mostly use C + throttle. The code is designed to be tunable, you can adjust the smoothing to make it come UP to speed more slowly, but as currently designed putting the stick at 100% means you get 100% throttle; the smoothing just makes it get there a little more gently.

If you hold C it'll "auto cruise" at whatever low speed, then hold throttle up and it will increase the cruise control speed, which is a lot more gentle than just mashing the stick forward.

Inverting the stick wouldn't be that hard. If you're interested I can walk you through the very few code changes needed to do it. I *think* it's exactly one line to change, but we'd want to test it :)
 
Unless something trully awesome comes up i will probably keep this program version.. I agree this remote frees up all the available esc speed. It feels faster than my Quanum

so what updates can we look forward to....Horn on the z button?
I use my squeaky brake sound as an alarm when walking around people.. but maybe a full fledged bip bip could do it... hell if we are going to put a digital horn on it make it play la cucaracha...
 
My gearing is 1:3 on 6s, so not super fast to start with, but it certainly does use 100% of the esc! :D I'd definitely like to increase the smoothing. It sounds like that would solve the acceleration problem. And if you could instruct me how to invert the joystick that would be awesome too.

Have you guys found a need to get a grip (no play-on-words intended) for the nunchuck? I covered my quanum in orange duct tape so it never got too sweaty to hold. Also I want to add a wrist strap. It seems the Kama has one, or at least a spot for one, but I'll need to drill holes for one in the Memorex.

Definitely faster! Quanum would frustrate me sometimes because even at full throttle I felt like I was getting shorted out of more potential speed.

I like your suggestion, Beto. There's a lot of untapped fun to be had with the addition of a speaker. :D Personally, I want something similar to Star Wars vehicle sfx. The combination of the right sfx with the sound of our brushless motors could produce something awesome.
First I want to try using Z to power on/off my LEDs.
 
you guys joke ... I actually have 10 piezo speakers I was testing but the little ATmega328 has a hard time doing "beeping" and "skateboarding" at the same time. Not loud enough for a horn either. I've had some luck shouting at people.

drmacgyver: falling back to PM to go over code changes, we can circle back here when you find a setup you like.
 
LOL, I'm surprised you guys have a hard time with that. Usually, everyone moves out of the way once they hear the motors because they aren't trying to get ran over.. lol -- unless there's like no space at all due to traffic then I'm forced to kick my board up and walk or ride on the streets.
 
No no, the motor squealing works like a charm. Not a problem that needs solving, personally.
 
Hi,

I've recently received my Wiireceiver and am trying to find an explanation of the red and green LED indicators. I scanned all the posts but could not find it.

Cheers,

Peter

They're for debugging purposes. There are a few patterns that will blink during the startup sequence, then the green flashes faster with more throttle, or red faster with more brakes. Once it's installed and working you can't actually see them (since it's probably stuck inside your battery/controller compartment). If you're having a hard time with it, a video of the startup & operation with those LEDs can help me troubleshoot remotely.

Have you hooked it up yet?
 
Those who are comfortable updating: can you try
https://github.com/jaustindavid/wiiceiver/archive/master.zip

Torqueboards and I were testing and I cleared an issue with startup / ESC sync. It works for his and my ESCs, I'd love to get confirmation from a few others. Thanks!
 
Loged in another 21 kms on the hobbywing.. R3 version loved it.. awesome.
Hooked it up to the hobbyking 150... no dice..did not even sync..
Figured something was wrong with the hobbyking board setup so i connected my quanum remote/receiver and the hobbyking spun up perfectly at the first try., reconected austin-s wiimote to my hobbywing and again perfect connection the first time around... :roll: Hmmmmm...

I have not received my hobbyking program card yet so my ESC it is still set at the 8mhz speed as oposed to 16 mhz..
The motor timing is still set at medium as oposed to high which is my regular setup
it still is at the original setting of forward/brake/reverse setup, so maybe in one of those lies the culprit..

Maybe Quanum/hobbyking are afraid of austin and torque's success with the wiimote and have decided to impede their plans for global domination?

Try newer code? My ESC is also 8 MHz, but that shouldn't matter -- the wiiceiver is sending a 50Hz PPM signal to the ESC, which should be the same as your Quantum. My best guess at a culprit is the startup sequence. You can try newer code, or with your RC3: start wiiceiver, hold full brake until the LED flashes wildly, then full throttle for 1 sec, then leave it neutral for 5s. That might be enough of a sequence to get the ESC in line.
 
will try it right now
 
Beto,
If you're calibrating the HobbyKing esc, the sequence is:
-Turn on power while holding the reset button (which is next to the power switch)
-Wait for the esc light to dim
-Release reset button and full throttle until *beep*
-Full brake until *beep beep*
-Release trigger to neutral - you should then hear *beep beep beep*
-Power off and on and you should be all calibrated

I haven't had a problem with the HK/wiceiver setup, so I hope this helps! I guess my only problem is that it works too well :D
 
Thanks Dr.. will try that as soon as i get back to the office..
Thanks for the tip, cause this ESC just wont connect to my wiimote.... Im sure it is all my fault though... Electronics are always smarter than me... :roll:
 
No problemo :) It does work with the HK though, so I'm sure you'll get it figured out. I'm pretty new to electronics too. Makes my head spin sometimes. But I figure doing this kind of stuff is good hands-on exposure to help the learning process. You learn the most from doing and we're in the company of great minds. :)

I've only hooked it up to a 4.8V battery pack. I was just trying to see if it would sync to the nunchuk.
They flash alternately on power up and the led on the numchuk flashes. When I move the joystick, the nunchuk led goes out and the red and green led go solid. I should be able to hook it up to the esc and motors on the weekend.

Cheers,

Peter

With 4.8V I'd expect it to perform normally, and solid lights don't sound normal. Try re-seating the nunchuck adapter, if it does that when connected to the ESC.

I'm going to give the update a try tonight. edit: After a few failed attempts and many messages to Austin I was successful with the update. I noticed an immediate change in how fast the controller sinked up. Great work on an already amazing Controller/Receiver.
 
I have paypal but I figured I could then buy the numchuck and it arrive at same time/close together.

Paypal is preferred. We don't sell them on Amazon if that's what you were asking. We also don't currently have any in stock. I'll know by the end of today we might have about 2 or 3 plug and play's available. I should have maybe 1 or 2 but there's quite a few people who are interested in purchasing them. I'll just post once I have them ready to be shipped and we'll just do a first come first serve for them until our big batch comes in.

Within a month or so we should hopefully have about 25-50 available.
