Turret Project: 2 servos + PIR + Turret

Here is the next project, a mini turret. Just the right balance of programming and electronics is required, so I think I can handle it.
First step will be to make the mount, then I will start messing with some PIR sensors. I will probably just write a simple motion program to check out the range of motion. This will become the start up routine.
If anything, this will show me if it is going to look cool or not.
With some quick solid modeling, I got the feeling it will make a decent looking paper weight :)

EDIT: After some thought and research, I am thinking that the PIR is not the route to go, and the easier method would be to use some IR Leds instead...we'll see. The possibility of using an off-the-shelf sensor still exists :D

Uno Platform

I wanted to give the Uno a temporary home with a little more "substance" and that would also allow adding an extra plate with buttons or switches or testing.
So, I made up a quick little sheetmetal channel with standoffs and rubber feet. It will do for now.

Update!

I received my Sensor Shield so I added a photo of that. Picture quality isn't that great.

Hello Servo

I was eager to get a little hands-on experience with the UNO and see how easy it was to upload to the Atmega328.
I used the default servo example and wired up a Futaba S3003 per the code comments (I was rushing, and got lucky I didn't confuse the data wire with the ground) and it worked fine!
Now I want to move on to something a little more interesting ;)

Got it!

For the longest time, I have been wanting the time, and resources to do some of my own electronics projects. Now, with this little platform, and clean programming code, I think it is doable. I went ahead and ordered my Arduino, and it arrived!
I am running Ubuntu 10.04 and recently downloaded the Arduino22 software. It is really awesome!
It has been a while since I worked with my projects, so now I have to get some supplies together.
