  • Kerning is the relative spacing between letters. Basically, you want the same amount of visual space around each letter.
    There’s a poster up here in Pittsburgh for the show ANTIGONE (pronounced Ant-ig-oney) that looks like it’s (ANT I GONE) because of how much space is around the I.

  • Fabulous sensor – just got it working on my bench after not playing with it for months.
    A lot more computationally intensive than http://www.sparkfun.com/commerce/product_info.php?products_id=8161

  • Oh my, that’s beautiful!

  • Anybody have a good idea on a hole size for mounting through a case?
    My first attempt at that led to some trimming of the plastic doohickey to keep it from snagging.

  • Any idea on the power requirements? Looking to battery operate it…

  • Looks like the change to surface mounted Xbee socket made it a little wider where the xbee is.
    They’ve also broken out CTS & DTR pins (from the Xbee?), which weren’t there on the last FIO I saw.

  • Anybody know the external diameter of the pole that comes with this?

  • In the next revision, it’d be really excellent to have the SS pin broken out somewhere on it, and roll/yaw shifted down two pins to free up the i2c connectors =)
    As-is, you can use the uart pins for an ss pin if you’re the spi master, but a board like this would like to be the slave so you can just poll imu data, or implement a software i2c, but no way to use the internal i2c or spi as slave.
    Anyways, I have some good working kalman-filtered roll & pitch code. My output code is not currently working, so it’s removed from this: http://pittsburgh.benpeoples.com/code/BLP6DOF.zip

  • Should perhaps also be noted that 40 miles LINE OF SIGHT is not exactly the simplest thing, due to the curvature of the earth. For connecting a 6' tall person to another antenna, you’ll need an 800 foot tower. Two 300' towers would be able to talk to each other 40 miles apart.

  • Cool! In retrospect, having the interrupt delay programmable (yeah, yeah, yeah, feature creep…) up to a few seconds would make for a super-useful for water rocketry where you don’t have an ejection charge to deploy your parachute. (Having it calculate the apogee time from the acceleration impulse would be gravy).

No public wish lists :(
