Wanna See My Speedo???

You guys are nuts. What happens when your iphone or GPS decides the vibrations are too much, and dies? Or it pops off it's mount at speed? Or you wipe the kart out?

Must be that "disposable income" I heard about...

Nahh. I have a blackberry that my dad used to have it for work. It has a case with a belt clip that you can wear around. I would just use the Speedometer app so I can see my max speed, or if I want to see my speed at any given time. Plus, it requires no data plan (it uses the gps) so essentially, my the speedo on my blackberry is free. And I think it will survive the vibrations if you are holding it, or it's clipped to you. I think the only time vibrations would be a problem is if you clipped it right to the kart it's self, without anything absorbing the vibration. So for me, I feel comfortable with my blackberry in my pocket, or clipped to me, in in it's case.

iPhones on the other hand... I have never been a fan of apple. And those things cost so much, and they have a touch screen to crack.

I admire the time and effort you have put into this speedo device toystory, to get it to that degree of accuracy is really impressive

Its one thing to stick a cellphone to your kart and get a reading, but a whole different picnic of fish to actually nut it all out and get it going from scratch

As for me the ol' eye-crometer doubles as the speedo, and most of the time is doesn't matter because im sideways , or down a bank

Yea, no doubt the bike speedo is better.

No disposable income here. Actually it has just a mode to keep your highest mph. So if I put it in it's heavy armored case and put it in my pocket it'd work perfectly

I highly doubt your GPS will be able to receive a signal from the 4 satellites it requires if its in a case in your pocket.

Thanks, Cam- I really do appreciate the props.

EDIT- A note on GPS speed readings- When I was sussing all this out and double-and-triple checking my calibrations, I did use my car GPS. I held it in my left hand, and steered with my right. Pretty freaky at 45MPH on a pothole-infested dirt/gravel road. At any rate, I did about eight full-throttle passes, each about 1/2 mile long in opposing directions, to get a fair average.

GPS units to take a little time to get a stable, accurate read.
