Hacking gym elliptical
« on: December 17, 2019, 11:30:23 pm »
Hi,

I just picked up a discounted NordicTrack Elite 11.0 Elliptical on Ebay, I want to hack it.

I would like to extract performance data and it would be great if I could control the elliptical to increase/decrease the intensity?

I can see the elliptical has an ifit port, I think this takes an ifit module which adds wifi to the elliptical, I think this might tie me to the ifit app though which is bad, anyone hacked this or know anything about it, maybe it's a serial communications port?

Maybe I can use bluetooth (might just be for heart rate), or even USB (might just be for phone charging), where do I even start?

Ideally if I could hack something together without having to buy anything proprietary or be locked into monthly subscriptions then that would be fab, it doesn't need to be fancy.

FWIW I'm pretty handy with computers and I can solder, I also have access to an oscilloscope.

This looks interesting:

Looks like some people just remove the head unit and replace it with a SBC like RPi (and display) wired into the sensors, I probably don't want to go that far.

I could buy the ifit module, they're going for around A$250 on ebay?

The optimal result is I can get data from the elliptical, into one of these "games" where you can race up the side of a mountain.

Thanks.

Richard
