use your wiimote to measure the powergain on your mods

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).

Here's a copy of the script that dumps everything out to output.txt
All you need is Glovepie v0.29, a Bluetooth dongle with BlueSoleil, the Human Interface Device drivers, and a standalone wii remote!
All the basic instructions on how to get your wii remote connected to your PC can be found here:

If anybody wants my excel spreadsheet with the formulas and graphs, you can find it here:
http://people.ucsc.edu/~klee/t...s.xls

//Glovepie v0.29 script

var.t=time*86400

//Writes motion data to file
OutputToFile(RemoveUnits(var.t)+","+Wiimote.gx + ", " + Wiimote.gy + ", " + Wiimote.gz)

debug = var.t+', '+wiimote.gx+', '+wiimote.gy+', '+wiimote.gz


The Wiimote, nice n snug so it doesn't jostle around:

Oh. That all?

Glovepie sounds like pr0n.

i didnt know you stalked the mkiv forums

[AcquaCow]

Yeah, just saw this today...

I wonder how accurate it would be...

If you don't have wii, use the Ross-Tech software to measure 0-60, 1/4mi and any speed in between. Anyone who owns a VW should have VAG-COM to begin with

Oh yeah, Glovepie sounds like pr0n but VAG-COM is a perfectly normal name

[orndog]

It is. ALL VW owners have VAGes.

I still don't understand why he didn't just use the accelerometers in his macbook...

It's got 3 gyros, tri-axial accelerometer, and 3 temp sensors...

You could do a lot with just the macbook alone...
