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

Would an FT2DR provide the same functions? Looks to have same features as the FT3DR. Might be a more affordable option. So what are the options for a tracker besides telegps and bigredbee? For sure, the FT2DR would work. Basically you need a radio with an inbuilt APRS TNC as well as a GPS chipset. ...

Re: Electronic flight cards

From a covid perspective, I'm sure that we could manage the risk of infection just as well through the use of hand sanitiser and gloves... +1. Realistically if the LCO has a sheet of paper on a clipboard to record the necessary details when someone comes up to hand over their flight card they don't...

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

I agree that radio is not cheap but it is a true single device solution, no cables or other software anything and all in a rugged thing you can run around paddocks and in utes etc in the bush without it getting ruined/falling apart/cables dropping out just at the critical moment etc I second this s...

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

Hey Sirbad, Sorry, I've not picked this up in quite a while. My Pixel that I was using at the time decided to brick itself December 2018 and when I moved to the 2XL I was greeted with a lack of headphone jack. I only recently picked up the Google USB-C to audio adapter, the cheap ones from Ali get r...

Re: What’s everybody up to during the lockdown?

I've been work from home since 13 March. I'm finding it good all considered and I'm very happy to still have work and be able to do it remotely. That said when I'm not working I'm finding sitting in my home office increasingly difficult to contend with outside of work hours. So as a result I've been...

Camera part 2

So after PK's thread regarding small form factor cameras it hit me that the GoPro Session lines have been OOP for some time now and there must surely be some new cameras available that are very small and adapatable to our use case. Fairly quickly I found myself on HobbyKing looking at some of the FP...

Re: Camera

You could try and find a GoPro Hero Session camera. They're roughly 38mm squared. But beyond that I don't know any off the top of my head.

Re: Model Rocket Survey

Done. FYI I put cost at $500+ because of electronics. Once you put GPS + a flight computer in a rocket you're nearly at that price point anyway.

Nice work PK!

I couldn't help but notice your fin cutting video was from early 2016. Thanks for making me feel a little bit better about the time it takes for me to get a rocket together!

Cambridge University Press just made their education textbooks available online

Subject pretty much says it all. Access is available until the end of May 2020. I've taken the liberty of narrowing their offerings in the link below to the three books tagged as Aerospace but you might find some value in the wider offerings. https://www.cambridge.org/core/what-we-publish/textbooks/...

Re: Running in the 90's - my Aeronaut Project

For altitude my guess is 150k... Because you'll be flying at Aeronaut. [emoji6] How are you going to handle your ISC? And have you considered using a M840 instead of the M2245 for your sustainer? I'd bet you'd get a similar performance apogee wise without the extremes the 2245 will put you through. ...
