    LTM in GC 

    Huge, huge feature for GC is in the works. This is Mark Liversedge’s take on LTM (Long Term Metrics). Something that I started a few years ago and I am sure now has ZERO resemblance of whatever I hacked up back then.

    I think the screenshot speaks best for itself. Using a SQLITE DB, it crunches all your rides and stuffs them into a DB. From there, it will be possible to select a myriad of combinations of ways to see your data. Lots of new features in the works for this including:

    Show critical powers on the plot
    - Show time in zones (bottle of sand)
    - Allow user to set bin width (years, months, weeks)
    - Allow user to filter rides to plot
    - Allow user to filter top 10s etc on plot
    - Allow user to modify curve color, style, symbol
    - Allow user to select date range on plot ala intervals
    on the ride plot
    - Define some preset plots e.g. Time/Distance, CPs over time
    - Support multiplots to compare years or seasons etc
    -Show critical powers on the plot
    -Show time in zones (bottle of sand)
    -Allow user to set bin width (years, months, weeks)
    -Allow user to filter rides to plot- Allow user to filter top 10s etc on plot
    -Allow user to modify curve color, style, symbol
    -Allow user to select date range on plot ala intervals  on the ride plot
    - Define some preset plots e.g. Time/Distance, CPs over time
    -Support multiplots to compare years or seasons etc

    Nice stuff Mark.

    Golden Cheetah 1.3rc2 is out. 

    With lots and lots of bug fixes, GC 1.3 Release Candidate 2 is now out: http://goldencheetah.org/rc/

    GC’s New Aerolab 

    Big, big buzz created by this last week. I can’t believe I forgot to post it.

    Fellow Montrealer, and all around good guy Andy Froncioni has created a Virtual Wind Tunnel for all you TT and Tri Freaks.  It created quite a stir on some mailing lists. It essentially allows you to determine which bike position is more Aero and thus saving you several thousands on wind tunnel testing. It’s still in Alpha stage but it appears to be working farily well at this point.

    There is a possibility to merge what Andy has done with GE. Sparkfun makes a Package Tracker. This package tracker has all that GE has plus barometric sensor, temperature sensor. Two key ingredients for Aerolab.

    Well done Andy. Another great feature for Golden Cheetah.

      GE + Aerolab would be a cool project. I’m in! :-)

    Golden Embed Two Successful Runs 

    With some testing and lots and lots of debugging, I have been able to run two rides recording Heart Rate data and Power/Cadence data using Quarq Cinqos. All messages were logged and no errors that I can see of.

    So for now, more testing is required but I’m fairly confident it’s working correctly.

    Next goal for me is to find a bike mount for it. There are lots of options and the best ones appear to be a custom run of an enclosure.

    Now I plan on actually leaving the house and get some fresh air !

    Golden Cheetah RC Candidates 

    The first Golden Cheetah 1.3 RC are being readied.

    A release cannot be far behind.

    GE: HR, Power and import to GC 

    We made some pretty decent progress this weekend. Golden Embed is now listening on two ANT+ Channels and I am able to record  watts and heart rate at the same time.

    As well, we were able to parse that data and then create a .gc ride file that could then be imported into Golden Cheetah

    GE in GCIt’s not quite ready for production however. ;-) There’s still lots of testing involved. I was getting a few power spikes that I need to look at (38,354 watts). My sprint is not that good!

    Great progress and I am hoping now it’s something to build on. I’m hoping now people will start to contribute their own patches.

    We are also in search of a bike mount. We’ve had offers for custom CAD designs and the ability to possibly make our own bike mounts.  If we can come up with something decent and usable to mount to somewhere on the frame, I think we’ll have something ready for the spring.

    It’s great to see how GE is picking up steam.

    Golden Embed: Time Stamps and a Website 

    With a Huge Thanks to Jim Ley GE now has a website:  http://chomsky.shampoo.ca/goldenembed/

    I’ve now also coded in Time Stamps. So time stamps are now tagged to the back of the ANT+ message. More info here:

    GoldenEmbed mailing list 

    Hi,

    For those of you who want to contribute or follow along a little more closely with GoldenEmbed, I have created a mailing list here:  http://groups.google.com/group/goldenembed

    Now parsing 

    I managed to get the parser in Java up and running. Code is here: http://github.com/jknotzke/GoldenEmbedParser I’m able to fully parse the HRM data out of the dump.

    What is left to do is to add in a time stamp. The time stamp will have hour, minute and second. The end goal for this project is to be able to import into GC. GC assumes 1 second sample rates. So I don’t need to handle less then 1 second timestamps.

    The time stamp will appear after the ANT checksum. This might lead to data corruption of the timestamp but in post processing I can fake a time stamp based on a previous sample. The advantage is if a time stamp fails, I still have valid ANT+ data.

    After that is done, the next and final step (for me) will be to handle Power and then Power with HRM.

    I noticed a few people have bought the hardware and are now starting to use my creation. That’s Fab!

    GoldenEmbed now soldered up 

    Happy New Year.

    I soldered up all the parts. This gives you an idea of what it looks like ready to go. I was a little nervous about doing this as my abilities with a soldering iron are on par as conversing in Japanese. Which is to say, very low!

    But, it’s working. The two boards are connected first by velcro. This allowed me to connect and disconnect the backs while slipping the wires in. It also ensures the two PCB’s don’t create a short on each other.

    The messages stored to disk are pure ANT messages. I’ve started to convert them to meaningful data in Java. I can read the HR data out now.

    I’ll make this more robust in the near future and then actually print out XML of the data. The end goal is to have Golden Cheetah be able to read this. Then, I’ll tackle Power, which, should be very trivial to do.

    The 9V battery is just to give you some perspective on what the size of the device is. It doesn’t run off a 9v. It runs off a 3.3v LiPoly battery.
