Got my 7 segment LED and shift register in the mail today. Wired it up and it pretty much worked the way I expected. I had to change MSBFIRST to LSBFirst, I had a feeling I had it backwards. If I had soldered the pins in the other order, that would have worked as well. Also, the 7 segment LED module I got is freakin TINY, I wondered what they meant by .28" in the description.. I think that meant each segment is just over a quarter inch long.. heh..
I also had my numbers off a bit, I needed to subtract 1 from currentMode to get the correct number to display from my array (starts at 0, not 1), and one other minor change to keep the LED from displaying 6 when I'm in mode 1.. smiley-wink
I'm looking forward to Christmas being over so I can move on to my next projects.. smiley

smiley Thanks. Yeah, I've been playing with MegaSquirt ECM's, which are a DIY electronic kit in a lot of ways. Picked up much of my skills from that. The programming, I used to program in Turbo Pascal as a teenager.. Hadn't done any in about 13 years, but over the summer I worked my way through two or three "Learn Objective C" books, because I wanted to get rich writing iPhone apps.. haha, that never panned out.. But it turns out I feel pretty comfortable programming in C on the Arduino now. smiley
I'm definitely looking forward to getting my two sons into programming and building things. They're a bit young at this point, so they just tag along to see what comes out when I get done building things. smiley
As for a next blinky light project.. I was leaning more towards doing a spinning disc with a row of LED's on it. I saw one on YouTube that was displaying words "in the ether". Very neat trick using POV..
But my next couple projects are less blinky, and more useful.. Knock based doorlock controller for the sliding glass door on the front of my house. It doesn't have a keyhole, so it's always a PITA to lock the house up when I leave. Arduino would solve that nicely.
And just for fun mostly, I'd like to make my garbage can take itself to the curb each week, and put itself away after the garbage truck comes through.. hehehe.. smiley

If anyone takes a look at the source, and has any feedback, I'd welcome it. Like I said, this was my first project, and I'm just learning to program the thing, I'm open to advice and constructive criticism on my programming.. smiley

 There's video of it in action, and I updated the page linked in my first post with the completed pictures, and a link to the sketch I have running on it. I had a bug in one of the modes (patterns) in the sketch I had on the Arduino when I shot the video, that's why it freezes at one point in the video. It's all better now.
I love this Arduino! smiley

They are solid state relays, meaning no coil. No need for a flyback diode.

I don't actually get my Arduino until Monday, but I'm ready to hit the ground running the second I do. I wired up the solid state relays and the high voltage side of things today. I have a bunch of pictures here:

It's not going to be anything crazy, no dancing to music or anything. Simply the ability to have a couple different patterns.. I'll have some video by Tuesday.

This is really cool, I'd never considered using an alternator as a motor. That's a brilliant idea.

I like it alot. Very cool. Can it calculate MPG?

bld: That sounds like what I'm planning to do. I have something much like a NAS (SheevaPlug to be exact) that I plan to do the same thing with. smiley

I'm still new to this myself, but I plan to do something similar. Check out the firmata examples, that should get you pointed in the right direction.

There are several ways to connect an arduino to an iPod Touch/iPhone. The latest iPod Touch and all iPhones have camera's built in, and very capable CPU's on them. You might be able to use the iPod to do the tracking, and simply drive the arduino as a slave.

I think the file is just that, Insurance.. Generally to prevent assassination, or a decade+ visit to Cuba.. Whatever is in it must be HUGELY worse than anything out there, something almost unimaginably bad. Otherwise, it'd contradict his proclaimed values about the freedom of information.
Sadly, if the information in that file really is THAT bad, it's a shame it had to get distributed. Someday, it WILL get cracked. Encrypted files can ALWAYS be brute forced, eventually. Whether we have to wait for Quantum computers or just a couple more iterations of moore's law, one way or another, it'll crack, and it's as good as out there for the public already.
