Wiimote Car Acceleration Monitoring

Categories: PC Connect, Wiimote Hack.

No need for expensive acceleration monitoring hardware when you can simply strap a Wiimote in for the ride.

“I got this idea after seeing some physics class use the wiimote in some kinda pendulum experiment.

Why not use the wiimote’s built in 3-axis accelerometers to measue g-forces, acceleration and even calculate my own 0-60mph times!

So I did. I wrote a script to dump all the g-force readings from the wiimote to a comma separated value file, then did some post processing in MS Excel, and voila, I can see every bump, every curve, my acceleration and braking, and even calculated my current speed using high school physics (v=a*t)

I even convinced my coworker to take me out in his E46 M3 to measure his SMG’s performance

I admit, it’s not super accurate since the wiimote spits out G readings rounded to two decimal places. It also provides other acceleration readings in finer granularity, but I couldn’t figure out what metric it was recording in. I used Gs since I knew it was just the acceleration of gravity (9.8 m/s/s).”

Do you have this script and Excel File for download? I’d love to try this thing.

can somebody put a easy wii-mote led mod
somebody answer

huh?… please be more specific… or make sure the words you string together make sense in that order. what do u want the mod to DO?

Check this out for a useful analysis program.
MapMaker can easily be adapted to accept input from almost any g-force or GPS based data logging system.

G is easy to calculate

We know that x and y are at 0 g’s when the wiimote is at rest as seen in the picture. Z is the axis going up and down. Z is noticeably higher number than x and y (which should be equal). x and y is 0g, and Z is +1g.

From this, we can calibrate to 0 and 1g, and by component forces, we can detect tilt of x, y, and z axes.

All we need is a definition of origin and knowledge of velocity (set to 0 to make things easy). From there, one would be able to record where you’re at from the reference position.

You’re so cool! I don’t think I have read a single thing like this before.
So wonderful to discover another person with a few
genuine thoughts on this topic. Seriously.. thank you for starting this
up. This website is something that is required on the web, someone with a little originality!

Unquestionably believe that which you stated. Your favorite reason seemed
to be on the net the easiest thing tto be aware of.
I say to you, I certainly get annoyed while people consider worries that they plainly don’t know about.
Yoou managed to hit tthe nail upon the top as well as defined out the whole thing without
having side-effects , people can take a signal.

Will likely be back to get more. Thanks

of course like your website but you need to take a loiok at
the spelling oon several of your posts. Several of them are
rife with spelling issues annd I find it very troublesome
too inform thhe truth then again I will surely come back again.
