AeroPod, PowerPod and Newton

The biggest impact I see on my own calibration of a P3 is tire pressure. I have set the pressure at 60-psi and ride for a few days - over essentially the same route. Reviewing the day's ride and analyzing the calibration may gradually show the factors shifting I then pump the tires back up to the or...

The next thing John is going to want is a ride file.

The last time I checked on any available data screen app for the Garmin bike computers, on the 2X2 Aeropod data screen was available. You were waiting on a definitive set of standards from Garmin regarding the output from the Velocomp power meters and how those fit into the Garmin data stream. So up...

This appears to be model building with various forms of data. What are the number of variables in this model - and - do you know that these variables are independent? Going through the "experiments" have you built a set of orthogonally designed experiments (DOE) that provide adequate varia...

As personal experience - when I first got my PP3 I was checking the calibration at the end of almost every ride. Every so often I would save the suggested changes - even when Isaac was only estimating small changes - the result for the most part was a wandering wind scale and friction values or slop...

Do you have the latest software update for your 520 plus? https://www8.garmin.com/support/download_details.jsp?id=15149 There are a couple beta versions at the location above - I think some of the more recent updates - even in beta - have a chance of capturing sensors better or more reliably. Tom

The Garmin, with its built in GPS can estimate your tire size (circumference) - What are you using for the tire size? If you allow the Garmin to do the measuring and then add that to your PP/ISAAC profile, the two should agree pretty well. Set up the Garmin, go for a ride at least until the Garmin w...

Looking at the simplified/iconic view of the summary - the power values include normal power (Norm Power) as the third line of the values displayed.

In case you do not have the link to the Update Page for the Edge 530 Firmware: https://www8.garmin.com/support/download_details.jsp?id=14953 They are presently listing a beta version of 5.28. It looks like 5.24 was the most recent previous version. What Garmin does do conveniently is to add the prev...

Just curious - I see you also have Garmin Sensors - There are LEDs that will flash right after they wake up for a short time. If you do not see the flashing, the issue could be batteries... I have the Garmin sensors (version 2) and the speed sensor is recommended to be mounted on the front wheel, no...

Try a different USB cable. There are a number of them out there that only provide power for charging, so not all the connections are active. - FYI a common way to steal data in public places (from laptops, phone and pad devices) is to have the charging kiosks have a device inserted that can grab the...

My PP-V3 shows FW 7.09 and does not indicate an update being available.

Velocomp/John are likely to want much of the math to remain their intellectual property. Cal rides in low wind allow the aero portion to use the bike speed as much as anything to estimate the wind factor. With a high wind, the bike speed plays less of a contribution and thus I suspect harder to nail...

I would think that as the angle of attack of the orifice on the PP is not exactly the same for each bike (unless there is a lot of serendipity) that these factors would vary (wind scale and aero). The same ratio is also not really surprising if it is the same PP as the sensor inside the PP detecting...

I never received a thumb screw with my PP, but I did get the allen wrench I do tighten it down - not likely to wobble at all. just tilt it forward as I secure it and it ends up pretty much at the same angle. I also have a long extender USB able so that I can leave it on the bike while charging and r...

Garmin offers the option to not include zero power or cadence in the average repotted values of these two parameters. (Not positive it will be true older Garmin computers, but certainly more modern models.) the Garmin Connect application will report NP and that conforms to the appropriate weighting ...

While in this case it sure looks like the PP tilt is radically different )not just identified by the friction coefficient, but also the tilt value), the answer to your other question about profiles - you can extract profile data from good rides. This feature is part of Isaac. So if you did not trash...

To add to that - there are USB charge only cables available - the data pins are disabled. This is because some unscrupulous vendors have designed chargers that also can steal data. SO many use the charge only cables - especially when at airports or elsewhere when the user does not have their own com...

I am a Mac user as well as a Velocomp customer from early on. I like what Isaac provides and anything else that I would like to see I can get from other software. Is Isaac an elegant package - no - but then I also think the Microsoft Office suite of applications is not elegant. Would I like to see t...

It is possible to modify the trainer coefficients to get your power into alignment with what you see on the road - I do not think you mentioned what type of trainer you have, nor what trainer settings you are using. If you browse through the trainers and the files that can be used - there are often ...

The Isaac application has been with Velocomp for a LONG time and there have been a number of Mac Operating System upgrades during all of that - as well as many changes to Windows. This is the first time that Velocomp has asked for a payment of any kind to HELP cover the cost of a significant degree ...

I have no way of knowing if the FW for the Edge 830 is in the same state of confusion - the latest release for it is listed as 5.0 - albeit that this model is newer than the original release of the 1030. I am going to likely have to wait until Spring to know what does work reliably for the AeroPod d...

Virtual Box, Parallels or VM Fusion - any of these can be configured to run any of the Mac OX versions (High Sierra or even Mojave - even an earlier OS) that remain 32 bit compatible. Build your virtual OS, then install Isaac and the National Instruments pieces and you should be good to go. You even...

I think the problem i sthat the PP V3 does not work with the dual sensor Garmin setup. Take a look at the literature for the PP. Right on the PP details page near the bottom of all the information and reviews: NOTE: An ANT+ speed sensor is required. PowerPod may be incompatible with these speed sens...

An image of the thumb drive will not work. The drive has other information that is needed for the Mac system to recognize that it has bootable information on it. An image file has all the necessary pieces for the rest of running Mojave, bot the key bits for the system to know that the external drive...

The Security folder should have been identified in a Relocated Files Folder - which also had a few somewhat vague words about what that was all about. The issues with that is they basically left it up to you to figure out where it was relocated FROM. Unfortunately there are many older files stuffed ...

I am wondering how many think and rely on the power values that come from any power meter, not just the PowerPod-AeroPod family as a means to summarily say something along the line - I worked hard and I know I worked harder on this last ride - or took it easy. Seems to me that with just about any ca...

I would think the most reasonable calibration reduces the unknown factors as much as possible - meaning that for a MTB riding on the surface where you are going to use the bike seems most appropriate. You might be able to take the MTB profile and improve that after a few controlled rides on the righ...

How about just the wind and slope? That's for us PP users - I'd like to get the information working - even if I have to write a routine myself. One that just displays these two data fields separately _-- LIKE all Garmin data fields.

I just got a replacement 830 - the previous one had issues with the compass (possibly more than that.) I was never able to get the AeroPod Connect IQ app to work on the first 830 and have since only had one ride where this app worked on the replacement. (Wind and Slope worked) Now, I am back to dash...
