ORM running on ISE SY-1750 Magnetic Rower

[RKC48]

Hi guys!

What a wonderful labour of love you have all put into this app.

I purchased another of those cheap magnetic rower types (https://isefit.com/en/cardio-training/293-ise-fit-rower-sy-1750-manual-magnetic-braking-system-vertical-storage-3760287793169.html) last year and was never impressed with the data shown on the monitor - particularly distance, which always seemed to be undercounted by a factor of 4-5.

Early April I decided to do something about these discrepancies but of course no response from my query to ISE! Research on the magicweb brought me to ORM and after reading many of the discussions decided this would be a good excuse to purchase a RPi and try my hand at setting it up on the SY-1750. Shades of that ZX-81 I bought in '82 or '83! It's been a great learning experience so far and from this morning I seem to be generating reasonable data, except the distance seems on the low side (409 strokes in 15 minutes @ 2630.3m). I've been comparing ORM data to my Forerunner 245 metrics for a reality check. Unfortunately I forgot to take a screenshot of the web dashboard.

I modded the rower by adding a couple of magnets to the flywheel and relocating the OE reed switches to a new bracket as the readings from the original magnet on the drive wheel (the one which is rotated by the handle belt) were undercounting and missing strokes.

Here's the original location of the reed switches with the jury-rigged RPi:

And the revised location:

So far my tentative try at updating config.js looks like this and any/all comment/suggestions will be well received.

'use strict'

I've been able to access the .csv & .tcx files ok via WinFileExplorer. I apologise ahead of time if any of the attachments/file uploads are bad, this is my first time posting to Github.

Thanks again,

Cool! And your welcome.

What we typically do is compare (when possible) to the times on a Concept2 (most gyms have one).
