Is this really lagless?
If so, take all my money
Lag should be at or under 8ms. Considering that most keyboards have this much lag (125Hz update rate) and I feel them to be lagless, it should be imperceptible. :)

I've gone and ordered the PCBs, initial prototype within 3 weeks :)
Yeah, it is lagfree, i did the same with my tatacon but i wired it to my arduino.
It was messy, but the main problem why i don't use it is because the sensors works really bad. I've two tatacons.
One of them was a fake one from china and the other one was the original one. The sensors were bad both of them.

better wait for the tatakon from Hori http://www.hori.jp/products/wiiu/wii_taiko/. It'll get released at 4.12 this year
Looks cool consider me interested
Bad news for impatient people - the boards arrived, but due to a datasheet error and my impatience, the nunchuck connector won't fit the PCB.

No matter however, because I've made a new version of the board and am sending it off to be manufactured tonight - it improves upon the old one by guaranteeing 1ms response times and fixing the connector. 3 weeks more waiting for China :S

Sorry for the delay, but I figured I'd keep people up to date on development :)

And a picture of the bad boards, so people know I'm not just fluffing about ;)
PCB Art <3
Hi, it's great if we can connect the tatacon without using wiimote / bluetooth, and there is problem to my bluetooth too. I can't even play it properly.
How is the development now?
I can't wait to see the finished product.
Wish you can make it soon and teach us. :3
P.S. I didn't reply but I've been checking this post everyday!!
Yeah, Christmas rush delayed me a bit :S

I've just realised I forgot to order the actual USB connector, so there's going to be a 5 business day wait until that appears...

I might end up just taking apart a USB cable and connecting that instead, but I'll keep this updated all the same :)
This showed up in the mail today so i am keen to see how good it is

It is also way bigger than i expected, the monitor in the background is a 27" for some perspective
As a fellow 27" monitor user... Holy crap that drum is big! Better speed up my development efforts, keen to see how that performs.
People with circuit making experience might understand the monumental failure I made with this board:

...That aside, with some awful fixes I now have a working prototype. Firmware is next, then software to configure what buttons the drum activates. Hopefully it'll be finished by the time the next (fingers crossed, the final) prototype arrives from the fab :)

Sorry for the lack of updates, I recently started a full time internship and have been pretty low on time to do stuff like this.

I've got the prototype working now, but there's still a 15-20ms input lag. Currently determining whether this is an issue with my controller or whether the tatacon actually has inherent lag (I hope not!).
No worries man take your time all looks pretty sweet so far, even if it might have a bit of lag it should still have better latency than Bluetooth and not having to pair the controller each time i want to play is a big bonus too.
What is the difference between this and the converter outside? But surely the circuit board art is fantastic ww
Damn your soldering is really neat :D
Nice job!
Hey there yo, just a little bump to let you know there's still interest in this project ;)
I'd be interested in this as well; just have to go pick-up another Tatacon (regrettably sold the Wii and PS2 ones I had).

A quick idea on the latency; can the converter do 1000Hz polling rate? Not sure what the device itself has to have as a requirement, but you can force polling rates on most USB devices with a custom driver/service in Windows, and possibly a program in Linux.

On a slightly different matter; how would this adapter compare to wusbmote?
How is it now?

I tried wusbmote with my Hori tatacon and it doesn't seem to work, the wusbmote is recognized as a game pad which osu! doesn't have support for in taiko mode unfortunately and also when i got to configure the wusbmote controller from the devices panel i get no button inputs from the drum. but i do get button responses from the nunchuck buttons and stick. I haven't played around with the config tool yet though so ill see how that goes

The config tool is actually a command line tool for configuring the adaptor and has only been tested in linux but apparently works in windows and OSX as well, i have only done basic arduino stuff before so this stuff is over my head and i couldn't be arsed trying to figure it out at this point and wouldn't really know where to even begin (probably at reading the full product description before i buy things).

to the OP I should also mention i am still interested in the converter just exploring different options in the meantime
GRUMBLE GRUMBLE this is the second time the forum has neglected to email me replies >:( I thought others had lost interest, and kinda forgot to check manually :(

I think the 20ms lag is in the controller itself and the way hits are registered - they seem to be capacitive switches, which are never really instant. I'm not happy with 20ms lag, so I'm somewhat stalled at the moment. I would love to be proved wrong.

As such, I've put my progress thus far on GitHub, (hopefully) ready for others to take a crack at. If you have an Arduino, you can buy a $2 nunchuck adapter from eBay (search "Arduino nunchuck") and play around - the important stuff is reading the status of the switches via i2c.

Sorry for disappearing for 2 months, I gave up and forgot people still wanted updates :(

If you want to take this further and are having issues, please PM me, I will be happy to assist where I can.
