Woo, Xensr and tape measure - at same time!

Someone please do this and post results!

I want the one calibrated to jump higher!

lol

I dont knwo how they work, think they are awesome, but just cant get my head around how they can be accurate to within a few ms without using an estimation algorithm based on acceloration or whatever too - do fast accelerating kites (c kites) register as much as slower ones - ones that fly up slowly - or the other way around...

mythbusters comes to kiteforum...

Easy - just put pile of construction site level lasers on beach and receiver on kiter..

So, how do they do it? Integration!:)

Before they double integrate z-axis acceleration to position they (IMU units) must orient themselves by using AHRS like Madgwick algorithm..

I found the lazer tapemeasure works well.I have it connected to a custom Bluetooth transmitter that sends data to my cell phone.I put a constant on feature with an upgraded battery for extended life.Mounted to the tip of my board for a true height reading.Working on the power output,trying to see if I can up power enough to cut through kite lines or leading edges for those pesky crowded days or for kook control.

Will that construction laser measure when it's bouncing off water?

I try to aim at it all the guys mowing the lawn on foils,I aim for their tin foil hats.
