L3… now what?

[Bruce R. Schaefer]

Sean, that was so cool! At least, I’d have a reason to use all those old 386’s and 486’s that I just couldn’t throw away… My next flight will probably be at Mach 1.5, and I’m thinking about some sensors to monitor the transition. That video was so cool… gotta go back and see it again. I have a book that I bought in the 60’s about making liquid fuel motors. I almost had my Dad considering it at the time. He was a combustion engineer. Had a neat garage, with my chemistry equipment and all his tanks, valves, etc. Hee, hee… 😯

I’m getting close to going for my L2 and am already feeling like I’m going to need something to keep me truly engaged in rocketry. It’ll be a while before L3, so in the mean time I’ve been thinking of other related projects. Right now, electronics is the top of my list.

That x15 recreation was awesome! And you’re right about the auto-piloted glider, it’s very do able, and with off the shelf parts. You might take a look at the Ardupilot project, and it’s parent Arduino project. Based on the ATMega328 processor (24Mips), and there’s a development environment to go along with it. Tons of possiblities, and dirt cheap processing power to run it.

I was reading about that. Check this out, number 4 & 5 down the page. 6DoF, plus I saw a 3 or 2 axis accelerometer at +/- 250 g’s. Too much, and there’s one that is +/- 16-18 g’s. The only ones I could find before were +- 3-4 g’s. Definitely too wimpy for HPR. But now they’re out there. I should move this to the electronics section. I’ll do that very soon.

Yes, there are a lot of sensors out there that people have hooked up to this device. 6 DoF accelerometers like you mention, gyros, baros, GPS, radio telemetry, servo control, horizon sensors. Other than tracking and data gathering, I was thinking maybe a stabilized camera platform could make a good branch project. It gets tiring watching all those spinning descents 😉

Self moderation – I like that.
