Check out the BeagleBone Black, or the STMicro discovery platforms. The latter is $12, has 9 axes of inertial/magnetic sensors built in, and probably has all the computing power you need, with a 72 MHz Arm processor. If you need…   Read more»

Thanks, Bear. Yes, I am taking a job at Moon Express in Mountain View, CA, and relocating the family out there. This is just too interesting an opportunity to pass up. But I hope to come back to Colorado in…   Read more»

I am looking for opinions on center of gravity, forward of center of pressure. From what I have learned so far is that the C.G. should be the airframe diameter, ahead of the C.P. at a minimum. My question is,…   Read more»

As for the lighting the outboard motors from the ground, that has its own potential problems, as has been demonstrated on a number of other failed or close-call big projects. When we go to smaller outboards to reduce the potential…   Read more»

Ken, I liked what you were saying about headphones but why not try my stethoscope and listen in that way as we rebuild it, then we could decide if we need headphones and headphone jacks. Maybe if necessary, depending on…   Read more»

Radar says that the North site got over an inch of rain today.

I always bring the rockets I find out there back with me. I look around but, man the prairie is big. I found 4 rockets at this MHM alone. One was Adrian’s from last year another was a Blackhawk 24,…   Read more»

I have had it both ways, benefiting from people finding rockets of mine that I otherwise would have lost, and having a frustrating multi-mile run-around,tracking my radio transmitter-equipped rocket back to the LCO table. On the whole, if someone brings…   Read more»

Now all day Friday and Saturday afternoon are showing 15-20mph winds, but Sunday is o.k. at little under 10 mph and Monday looks better yet. No chance of precipitation other than a small chance of evening thunderstorms on Friday and…   Read more»

The site, above, lets you scroll through both altitude and time. On Friday you’re looking at 60 knots (70 mph) at 18,000 feet.

Here’s a good upper level wind forecast site. The forecast for Friday is for a 150 mph jet stream to be centered over the launch site. Hopefully it will move off after that.http://aviationweather.gov/adds/winds/

The forecast has mostly improved since yesterday.Friday: 15mph SE wind all day, 30% chance of afternoon showersSaturday: clear, 10-20 mph SE windSunday: clear, then increasing clouds, just 3-6 mph windMonday: clear, 7-12 mph Westerly…[Read more]

Ooh, that’s a good name.

Sorry you couldn’t make it, and thanks for letting us know.-Adrian

Not me; I’m still L2.

You can get tungsten powder from Amazon, but it’s not all that cheap. People use it for weighting golf clubs. It’s about $15 for 1/2 lb if I recall correctly. It’s a pretty easy way to shave 1/2″ off of…   Read more»

The Russians must have been watching our MHM flight last year and decided to copy our technology//www.cnn.com/2013/07/02/world/europe/russia-rocket-explosion/index.html?hpt=hp_t2

Thanks. That seemed to work. It’s processing now.

I thought by now, Adrian would have had all the data posted.All the g force curves showing, when and what moters fired, ejection charges fired, directional g-forces on the rocket…………… and what Soda Joe was drinking at the time. I…   Read more»
