Shadow Box, where'd it go?

[WesternSkier]

Does anyone know what happened with this idea? I've been searching the interwebs looking for it and keep coming up short. Anyone have an idea if there is anything similar out there? Looking for a similar device that could potentially be attached to ski(s) for live feedback if possible? Anyone? Anything?

I have not seen anything on shadow box for several years. There was supposed to be a new rev release about 2 years ago. That was the last I heard. There is another product called "ripxx" The website is showing that they are out of stock and going to release a new rev. I have not done any home work on them at all. The concept sounds great and I would think that trickers and jumpers could get great imfo back. Could not even find price info. I want to say that the shadow box was about 550 - 600 ?????

Price at 329.00 but not in stock.

I used to talk to the engineers from ShadowBox. The company was sold and then new owner pissed off the engineers so they left.... Some started a new firm doing other bio mechanical stuff. Yes this is a loss and yes I have searched high and low for something like this...

Excellent value for money.

@Phil2360 good luck reading that raw data

[Horton]

@Phil2360 More to the point I talked to those guys and they told me I would not be able to make sense of the data. I got one anyway and they were right. You need some pretty heavy custom software to convert that data into something you can learn anything from.

 

Maybe @Than_Bogan needs a winter project that does not involve 10 sided dice and chicken sacrifice.

@horton, wouldn't mind having a look at some of you data if you could send some.

 

Think I could find some novel things to do with a toy like that.

 

25 years in IT, has me curious.

 

Cheers

@phil2360,

I was thinking the same thing. @horton, pass it this way too if you have a sample pass.

[Horton]

@Phil2360 no idea where that data is. Had Phd aerospace guy look at it.... Pretty sure it is not a matter of a bitchn xls...

[ToddL]

Per their website, there are lots of examples of nifty charts. Someone has a template in excel or some software which generated those graphs... I bet the company could pass along a contact email to their example customers and ask them to share the templates...

 

Heck, they would be smart to gather those template documents and make them available to the new customers as a starting point.

[Horton]

They were very patient with me.... We want the tool to do 1000000% more than anyone is using it for.

@horton, my background is writing code for 3d scanning, data acquisition, and optimization algorithms.

If you do ever track down the data, or take the unit for another ski, I'd love to see what data it spits out.

A few years ago we put a lot of time and money into a high end version of shadowbox (cost about 5000 bucks for the GPS unit if memory serves me) Produced some amazing data but the limitations of time, limited market and the basic inaccuracy of GPS to map it accurately to the course meant we stopped before it got too far. Only did jump at the time but the same principles apply to slalom.

 

For the nerds out there some links below to the graphs produced and also a 3D animation based directly on the data

 

 

Data is:

Map of skier path on a virtual course

Speed

Acceleration

Rate of acceleration

A made up 'Power Factor' based on angle, acceleration and location relative to the boat

For those interested the GPS unit was the SPI Pro X from GPS Sports

Found this lying around - gives a realtime view of the playback data
