I got out and launched some more rockets. Although it doesn’t exactly compare apples to apples, you can see on the image to the right that things either went very wrong with my initial iPhone launch or the GPS data I’m getting is screwed up.
The black line is a flight with the red iPhone rocket [...]
I noticed I haven’t been posting too much here lately and it’s because I have been posting elsewhere. I added The 365 Days of Astronomy Podcast to my blogroll. Check it out! It’s going to be really cool and I need your help to spread the word.
We also have a few new things over at [...]
Finally, here is video of the 3 launches of my iPhone. The first one is the failed launch due to a motor failure. The 2nd is the one where I got all the data that I’ve posted. The 3rd one I got almost no data but the motor performed better as the flight seemed [...]

I’ve been meaning to put my video stuff together but have had some technical difficulties. I’ll get that finished up soon!
If anyone from Apple should stumble [...]
A further update from my previous post on my iPhone rocket launch.
This is kind of a cool plot using only the GPS data:
Here is a plot of the first few seconds of the launch from the accelerometer:
You can see that the data peaks at 3g when I was expecting 12g. The acceleration heads back up [...]
So…I’m sort of an obsessive person at times. I had two simultaneous obsessions going, iPhone development and model rocketry. I’ve posted a little bit about both of these. One late night I had an inspiration — I should launch an iPhone in a model rocket!
The reasons were obvious: the iPhone has a 3D accelerometer in [...]
Apple is the latest company to release a product without having enough supply to meet demand. If this is a marketing tactic it is the dumbest goddamn marketing tactic I have ever heard of. You still can’t buy a Wii, for example, from amazon.com. WTF, guys, do you know anything at all about business? Now [...]
