Depending on how the 3D printed part is incorporated, it's actual strength may not matter much... My BALLS rocket was minimum diameter 75mm M that went to 26 K feet. the body/fins/nose were fiberglass but all interior components were 3D printed with simple PLA (!) including a test of 75mm...

[Ignoring the copyright issues for now] I have used ChatGPT to get specific code examples Ex: "Can you generate C code for the Python Huber Regressor...?" It does indeed give me code - but that I then have to test against the python version across some quantity of datasets. I've also asked it...

Tim - are you still getting that error? I think the iFIP install / update should still be working although I will be trying to validate and migrate to the "Featherweight UI" version for BlueRaven and Tracker...

I'm still busy with my regular day job but really pleased that Adrian has been able to find a developer with the time and skills to deliver these capabilities for both platforms! Now, I myself hope to soon have enough free time to work on some rockets that use the BlueRaven and Tracker while...

Sorry about the miss on the expire date. That was my fault and when it happened yesterday, I was on a rare 24 hour trip to Phoenix and back. I got back this AM and did the update so we are good for another 90 days. And as Adrian noted in the other thread, he is working on getting the tracking...

Tony, what does the other side look like? the other side has the radio and blue tooth chips on them... i don't know if comms are dependent on an active GPS chip, but it might be possible to still get the data... (maybe). We can also use your phone log for 1hz data if you want.

Nice to have a second generator to compare to... I now see above that I used feet instead of meters for altitude which is why my flight looks so high... :) This pic has your KML on it as well (the green)...

Patrick - I started this thread and then your thread showed up in the 'Similar Threads'. I just skimmed through your thread now and am impressed by what all you implemented!! So.... I'm still interested in people sending me their files to incorporate into a combined BALLS flight data - but...

I just saw a thread started by @Arpak back in January for a CSV->KML converter they wrote. I will have to review those features as it looks like they had good progress on KML features... :)

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...

it looks like bank 0 (which is calibration and deployment settings) is still blank. I think that is causing it to get into a loop of trying to re-read bank 0 hoping for a better answer. After I get back from vacation, I'll need to get you more information so that it should program it with the...

Could you do me a favor and do the same thing as above, but then go to the upper left of the dos window and click on the icon and then do Edit> Select all and then Edit> Copy and send me that text? I'll see if I can figure out what it is not interpreting right... Thanks! If you need to send...

ok, that means it isn't finding something in the response that it is looking for, but it is encouraging that the altimeter is responding with what looks like possibly reasonable results. I'm about to head out for vacation tomorrow but if we can't figure it out before then, then I'll take the...

Ok, first you get the "cheat codes" for getting a debug output window.... [this has never been published before... :-] Hold down the CTRL and SHIFT key when you click on FIP to start it. Windows will ask if you want to start it in Administrator mode. Continue to hold down the CTRL and SHIFT...

When FIP first connects, it wants to ask the Raven about it's configuration and flight data. It appears to be hung on that so not proceeding. Let me see if I can find what commands it is sending and see if you can reproduce those in your COM interface program.

Adrian - Good to hear the progress, Sorry to hear the troubles, And fully aware that I totally didn't have the bandwidth to have been able to contribute...! Best wishes and I'd still like an early unit to work with when you get a chance!!

That is certainly one we would keep.... !!

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...

Yes the firmware didn't change - just an app update / refresh.

No problem! I forgot, I also got these bits for the counter sink in the nose cone. https://www.mcmaster.com/catalog/2917A2
