Petra

So a few weeks ago, I was doing cameras at church. Or maybe it was during the 6:33, our Tuesday men’s group. In either case, the subject was brought up in the sermon that after Jesus’ crucifiction, Peter had denied Jesus three times, and all that, he basically got really depressed, dropped his calling and went back to fishing.

The verse that really got me in this sermon though, was Mark 16:7 – “But go, tell his disciples and Peter, ‘He is going ahead of you into Galilee. There you will see him, just as he told you.'”

Phil Keaggy – Maker of the Universe

So I happen to like good “cosmic” worship songs. Hymns about space and stars and stuff just kinda get to me. Last night, my dad was talking to a guy about a Phil Keaggy song that was taken from an older hymn titled “Maker of the Universe.” Overhearing the lyrics just blew me away, so I asked him to send me the link to the full rendition also. Here it is:

AR.Drone – Infrequently Asked Questions

Just recently (like, yesterday), I received my first (and hopefully long-lasting) AR.Drone 2 from Parrot in the mail!

This thing is a four-rotor remote-controlled copter operated with an app on my Android!

So far, I can say I’m fairly happy with it, save for the stock battery which, in short, is really really sad.

However, with a bit of research on the web, especially at the Parrot, I’ve found out quite a few things about this device which isn’t covered in, say, the user manual or the quick start guide.

So I’ll cover a few of what I’ll call my “Infrequently Asked Questions,” since there are plenty of FAQ’s out there and they all say about the same things, which, for someone with at least a LITTLE programming background, should be pretty straightforward. However, there were a few things which I could not find any mention of that I found particularly interesting, or notable.

PLC and Hardware Control

Aha! Thank you, Dad for my new Arduino hardware controller (and the partially-outfitted Craftsman toolbox to make my life simpler when building stuff)! Easy easy to program, and easier to wire up!

There was a time a few years ago that we were playing with a Seimen’s PLC at my old job, and the process to program it via their development package was more confusing than anything. I’ve seen Lego Mindstorms being programmed: VERY complicated. Arduino has taken these shortcomings of other PLCs and simplified -everything- to make these things easy to understand. All you REALLY need to know is basic electronics and basic programming structure (preferrably in C) and you too can program up one of these things.
