Crazy Wiimote control ideas... anyone got info?

<< < (8/8)

JKJudgeX:
Sorry to post 3 times, but, I just wanted to say that the point of making an IR LED like that is really just for testing purposes... if someone has a good product, I say go ahead and buy it, but, it might be a good idea to get your setup in place with a homemade setup (since you guys probably have this stuff laying around), or by just using your nintendo Wii's sensor bar (just turn on the power to the Wii and bring the sensor bar over before you run glovepie, works like a charm with 2 LED sensor solutions). 


Ginsu Victim:
Alternately, you can buy IR leds, resistors, and a project box at Radio Shack, then hack a USB cable for 5v power and step it down with the resistor.
Cleaner job, and no need for batteries. (If you do want it wireless, you can pick up a cheap battery holder too and skip the USB cable)
The thing to be sure of is how much power the LEDs need.
Seach for a "resistance calculator" online to figure what resistor your IR LEDs need.

JKJudgeX:
Yes, do it GinsuVictim's way if you have time/money.  Pretty sure you could get that project done for the price of a spare USB cable + about $6-8 at radio shack and have a much nicer result...

It's actually what I would have done had I known when I went to get my wires that I'd be making a sensor bar...  I got home and hacked that together at about 10PM, far later than Radio Shack is open.

I guess the biggest advantage of either way is that you get to decide the form factor of your LED Bar, whether it's wireless, etc...  I don't want to buy a sensor bar shaped anything like what the nintendo one is, because it's waaay too wide, unnecessarily, and that severely limits how close you can get to it (the Wiimote has close to a 45 degree viewing angle with its IR camera, so, the closer you get, the more likely you are to only be seeing one of the two LEDs).

I believe that there are 2 LEDs on the default sensor bar primarily for determining the Y rotation orientation (I think it has internal gyros and such that help determine this as well, not 100% sure) and/or the distance to the WiiMote.  For *our* purposes, a single IR LED should suffice.  I've had some trouble with 2 IR setups using my sensor bar, as it can jump and wiggle if you accidentally occlude one of the LEDs.  This is why I have scripts for both 1 IR and 2 IR modes.

Some people put a piece of electrical tape over one of their IR LEDs in the sensor bar, I've read...  but, I assure you, with the information and scripts I've posted above, and your own LED Sensor bar (bought, Nintendos, or made either way described in this thread), you can get a rather surprisingly accurate mouse pointer (Suitable for shooting games outside of mame, such as the ones at WiiArcade, even)...
 
Anyway, good luck, and keep the info coming... (I'd love to see more screenshots/info of homemade IR sensor builds.  I don't have the expertise to do the USB power-cable thing and would love to see how it's done, if anyone has the motivation/skill/time to throw one together and take a few pics)  :)

just an example of the wiimote being used as a steering wheel on a system that doesn't even have the wiimote (this is N64).

I've seen a video of two people playing SNES (I think) mario kart with a wiimote as well, but was unable to find it prior to posting.

It stands to reason that with good scripting that can allow *decent* play of these games with a wiimote, that good scripting could also enable us to play some driving games.  Albeit, we may not be able to actually *beat* these driving games without a few extra tokens this way, it would still be fun, nonetheless. for those of us without arcade wheels.
