  • I know what I'm spending my freeday money on. Sparkfun read my mind!

  • Amen

  • I have a similar pair of crimpers, perhaps slightly different, that is actually too narrow for standard servo connectors like futaba or hi-tec varieties. It still works, but you have to crimp twice for both insulation and conductor.
    What you want is something like
    for servo connectors.

  • Google this, there is a lot of debate over whether or not the magnets are snake oil. I'm personally of the opinion that they wouldn't work, because they wouldn't change the inductance.

  • Anybody know if these perform better at 2.5V than 3.3V? aka, more accurate compass results?

  • You will be hard pressed to find something that keeps up with your rocket. Most consumer GPS modules have 4G limits in their filtering firmware, so your acceleration above that is considered noise, and filtered out. Additionally, your top speed may be above GPS receivers can track using a standard correlation search. Your best bet is to pick up one of the GPS RF front ends like
    SiGe GN3S Sampler v2
    and implement your own correlation software to post process your logged data.

  • The crimp pin variety of these is a pain in the behind! I think the official crimp tool costs hundreds of dollars. That being said, there is an IDC version of this connector that when used with the correct awg wire can bring cable assembly to a couple of minutes.

  • So did you also fix the orientation of the D2523 for the test as well?

  • But CEP 2.5m sounds so much better than R95 5m!
    Also, isn't a velocity of 0 m/s a valid observation for the Kalman filter? I have no hard evidence, but I would conjecture that a faster moving GPS only appears smoother and more accurate.

  • I wish. Most data sheets for receivers will say 2.5m accuracy. This is CEP, which usually means 50% probability it will be within said radius.

No public wish lists :(
