    Send me your BALLS.... Featherweight Tracker Data that is....

    I'm going to work on compiling a KML/KMZ file for Featherweight flights from BALLS 2023. If you can send me your phone log (1Hz data) and/or the download from the tracker itself (10hz), then I can add the flights to the KML/KMZ file (image below includes 'basic' drone pic overlay onto GPS...

    The Featherweight voices in your head...

    So there was an issue on iOS 16 on how one screen was laid out so I fixed that, but in testing I found that iOS 16 has quite a few new voices that you can pick from - including many that might not "play well" at a launch... Notably "GrandMa", "GrandPa", "Good News" and "Bad News".... and other...

    Featherweight Tracker - Balloon - 90K Feet - 20 Satellites - all good...

    Here's a screen shot from a user that launched a tracker on a balloon. I'll post more info if I get permission (and hope to get phone log of flight to convert to KML) but nice to know that at 90k feet, the Featherweight still has good GPS lock and transmission back to the ground station. Note...

    Featherweight Tracker - Some iPads don't have a GPS so can't be used for tracking...

    There has been a perplexing issue where some iPads seemed to have problems with the Featherweight Tracking app. The symptom: "The arrow is basically stuck pointing in one direction, the elevation 'bubble' is stuck near zero, and distance usually says the rocket is really far away." We now...

    So if you have updated to the 'build 50' of the iFIP software for the Featherweight tracker, you should know that if your device is on iOS 10 or higher, it is recording the BLE packets - all of them received by the GS. I'm working on review / share / playback capability but just wanted you to...

    This screen shot may not mean much to you yet, but it is the start of porting FIP over to Java so it is available on Windows/MAC/Linux... and the #R and #D came from the Raven via USB/Serial to Java... One of the prior complications with the Mac WINE attempt was getting the USB/Serial to work...

    iOS/MAC/BootCamp/FIP

    OK.... so I have a Mac-Mini and have some want/need/desire to investigate better MAC/Featherweight integration... My first step is to get the 'standard' BootCamp / Windows dual boot install working. I have a Windows 7 Pro CD/license dedicated to the task. I'm going to start the process myself...
