Re: Joe Turner's 38mm Scratch-Build

AHAHAHAHA!!! The old "my aluminium tip is off axis when screwed securely" issue. This is a standard thing with those PR FWFG VK NCs. And you solution is exactly the one I use. Tape around the coupling cylinder between the metal tip and the FWFG. Don't feel bad about using tape for this sor...

GoPro HERO 5 (2018) is actually a firmware crippled HERO 5 Black

Title says it all. The 2018 model GoPro Hero camera is from a hardware perspective identical to the GoPro Hero 5 Black camera and is crippled by firmware to disable inbuilt hardware features such as GPS and 4K 30fps video recordng.

The UV-3R just arrived! Not bad considering I ordered it on Sept 3rd with free shipping.

Man this thing is small!

Re: GPS, APRS, and serial (or how I came to realise that redundancy and data are both good things)

So I've been meaning to chime in with another update, so here we go. First off, I think it wise to take a step back and look at what I'm actually trying to accomplish. Bear with me, we'll get there in the end. It's worth mentioning that there are two things that we require to receive and decode APRS...

+1. That's an amazing video which I can only assume took a ton of work. I almost don't want to ask but how difficult was it to get the speed and altitude data to mesh with the GPS track?

Re: Don't Debate This, Too

Regarding mass ratios though, an interesting point themselves - As built, at the moment this is where I am: 41.2 lbs - Rocket - measured weight as it sits right now, missing a few minor items, but call it about 99%. 19.89 lbs - Propellant - stated weight of propellant per ThrustCurve.org Propellant...

Re: Joe Turner's 38mm Scratch-Build

Question: Aside from weight, and extra effort to set up, I can't think of any issues with combining extensions.... Can anyone else? If it gets too long and there is a weakness in the middle of the extensions it may want to buckle under high thrust. You can work out your peak thrust and see if it is...

Re: Australian Rocketry shipping container pre-order announcement

Order submitted, deposit paid!

I've ordered a L265 and M840 for use in a two stage MD flight. I ordered a 75-6G hardware set for the M as well.

I've already got a M2245 and L935 that have been sitting in storage with Blake since 2016. I'm going to be busy at THUNDA. :lol:

Re: Vertical Trajectory System (with some 3D printed parts)

I gotta say OTT the above root cause analysis of your electronics fault is absolutely amazing! Well done on finding the likely candidate for the fault, I'd still be scratching my head if it were me! Good luck on the next test.

Re: GPS, APRS, and serial (or how I came to realise that redundancy and data are both good things)

So I've been meaning to provide an update to this thread. Here we go. First off, my above TeleGPS Configuration screenshot isn't correct as the APRS Interval(s) value is 0. 0 effectively means it's off. Below is the correct "working" configuration for my VX-8GR. Notice APRS Interval is at ...
