AeroPod, PowerPod and Newton

Do the draft/beta proposals for an ANT CdA profile include non wind speed and aero drag measurements? Are any other AeroPod relevant profiles being proposed for addition to the standard (e.g. altimeter or accelerometer)? I'm thinking about measurements like altitude, barometric pressure, slope/grade...

I respect Velocomp's right to control their IP as they see fit, and I am willing to sign an NDA. However before putting you through that trouble, I think I should get as far as I can working with what is available in the CSV files Issac currently exports. Then if my results are promising and pursuin...

While we are at it, probably should be including both pressure sensors (i.e. wind/dynamic and barometric/static).

It looks like exporting AeroPod ride data from Issac in CSV format produces 1Hz data, and that data does not include accelerometer data. I gather the IBR format files Issac downloads from AeroPod include 16Hz accelerometer data (if powerstroke is on). Is there some way to export the accelerometer da...

I am trying to do some roll down testing using a hill. I tried setting high values for Crr and CdA, and used the repair for missing cadence tool to try and get "power" while coasting. I get a few single sample spikes in the "power" and sections of the coast where the "power&...

I recently installed Isaac 5.1 on my mac laptop, and found that the recommended procedure would not work for my situation. I was only able to install the required "drivers" by using a work around that involves terminal commands and booting in recovery mode. I am posting this information he...

Could you elaborate on your "high precision laser scan" for elevation?
Are you working on a velodrome or open roads? How do you get your elevation data?

velocomp writes: "AP intentionally shows 0 wind speed if bike speed is low " I have noticed this and really don't like it. If I'm stopped for some reason and the wind is blowing in my face AP should be showing the wind speed in the garmin IQ data field. Is there any chance of this being ch...

Thanks John, Is the "better accuracy" | "best accuracy" selection profile specific or a device level choice? Is there a way to check which accuracy choice is in effect for a profile (I don't find it in the profile editor dialog)? Is the 0-100 calibration mode described someplace ...

BillOsler wrote: "... not what I would expect from a user-friendly product. ..." My experience with AeroPod and Issac so far (a week or two) is that they are not (yet?) user-friendly products. Feels much more like beta to me. I am willing to accept that, and work with it on that basis and ...

I don't thin the AP garmin IQ app/data field is in the garmin store yet. You need to grab the *.zip file (and the instruction pdf) from the first post in this thread.

1) for the bike in question I do not have a DFPM so I am using profile 1. Isn't that proper? I plan to use profile 4 with a different bike on as soon as I install the fsa powerbox crank I bought for it. 2) Is the first half of the cal ride counting up to 100 watts indicative of a known fault state t...

The garmin IQ data field for AeroPod shows gradient to 0.1 %. How is this measured? Is it a direct measure of the inclination of gravity with respect to the AeroPod? Is it derived from the velocity (from the paired wheel sensor) and changes in the barometer reading? Is it some sort of filtered combi...

does your power reading hold at 0 until you press the button? do you stop again after the light starts blinking before pressing the button? does your power reading count up to 100 during the first portion of the cal ride and then drop back to 50 for the start of the second portion? I am beginning to...

How would the result of recording an out and back ride and doing an "analyze->check cal" on that differ from the result of repairing sensors and doing the automated out and back cal ride process?

After pairing sensors to the AeroPod, does one start the out and back cal ride immediately or does one ride to where one intends to do the out and back ride and hit the AeroPod button to start the cal ride process? I think I have experienced both behaviors from my AeroPod.

I tried to / did a cal ride with my AeroPod today. When doing an out and back cal ride, I expect the power field on my garmin 820 display to count up from 0 to 50, then hold till I stop and turn around, then count up from 50 to 100. When I did the cal ride the power display counted up from 0 to 100,...

Are replacement pitot tubes available for purchase?

I am interested in perfecting the profiles and calibration I use. To that end I would like to understand some of the details of AeroPod calibration and profile content, so I have some questions. Sorry if this stuff is documented someplace that I missed. If it is please point me in the right directio...

Does the equation AeroPod uses to covert air pressure to wind speed have air density in it?
If it does, how is the air density value determined?

I think I read that the AeroPod can store about 26 hours of ride data. Starting from a full charge how many hours of data recording will the battery give? I think I read that after about 20 min of zero bike velocity AeroPod will close a ride file and go to "sleep". I think I read that it t...

Yep, one thing I've found during a career in engineering is that clear unambiguous terminology that rarely confuses can be surprisingly hard to come by. I agree that the terminology you use in the Issac software is very descriptive and clear, and I applaud your choice to stick with it.

In sailing (where wind is very important) the accepted and long standing terminology is: "apparent wind" is what an observer on a moving platform experiences. "true wind" is what a stationary observer experiences (i.e. wind with respect to the ground) So "apparent wind"...

Hey John,
Though on the one hand I appreciate your prompt action on this, on the other hand I'm a bit concerned to see your working on easter morning.
Pace yourself, and maintain good work life balance. We want you in this for the long haul.
thanks

I think it would be good to add this status light table document to the "comprehensive instructions for AeroPod" post.
Also, will this be unchanged with firmware update 7.06 or is there a status light indication for the new 5 min calibration period at start of ride when using profile 4?
