So after a lot of experimentation here is the setup I have settled on for the portal turret. The breadboards are only for the prototype stage and won't be part of the final setup. The turret has a small motion sensor in the lower part of the picture that is connect to the arduino. Every time motion is detected the setup randomly plays one of 17 audio clips through the sound board(the red one). The sound module in turn is connected to a small speaker that has surprisingly good sound quality for 4 dollars. I really wanted to make sure tracks were not repeated too frequently so the system randomly shuffles the 17 tracks and then plays 1 track each time motion is detected. After all 17 tracks are played, the system reshuffles the list again. As an added bonus there will be a small button on the turret that when pressed will play the portal theme song. The system will have the ability to be powered by either the internal battery source or with the flip of a button, be plugged into the wall with an adapter so it can be left on without worry of constantly needing to change batteries. The only other piece not featured which I will post images of soon is the eyeball. The 4 LEDs on the left are part of the eye and glow bright red.

My old Sony Super Walkman. This thing was extremely small for its time, and the digitally-tuned radio was a rarity as well. On the other hand, it was rather fragile, despite its all-metal case.

A simple counting machine I designed and built for my son. Select the value with the dial in the middle, then push the green button to add it to the total or the red button to subtract it. The case is laser cut from bamboo.
VCR tape, flip phone, and portable CD players. I remember portable CD players--they did not last long. Because every time you took a step the CD would skip. CDs need to stay very flat while they are playing

This is a little clock I built playing with hobby electronics and arduino at one point. I don't think I ever got it to work completely right but I like all the little details for this photo.
This was an attempt at an image for next week's Macro Monday's theme (technology) but I think I am going to go another direction for that so posting this now.
Detached view.
All pieces in my collection work and are in excellent to mint condition. Please do not use photos without permission. If you ask I'll most likely let you use them with a link back to my site. But, please don't steal.
This was my view for much of the night while finishing up some freelance work. I didn’t have too much time to find an interesting shot.
(I didn't make it.)
You look at it and say, "Cool, a Yoshimura-inspired speaker." Yeah, that's cool, but it LIGHTS UP WITH THE MUSIC TOO! And it matches my iMac! :)
Multicolored sound-reactive origami rave speaker has to be one of the finest inventions.
This interesting sculpture sits out front of the Nepean Habitat for Humanity "ReStore" for E-Waste. It's quite the sight to see where one does not expect to see it!
You can see the top has a little bit of jitter, This appears to be a timing issue. But I can't seem to figure out why.
Code here, let me know if you make interesting modifications :D (See also the forum post)
UPDATE: I created a new thread, in English, for NTSC with updated code.
This is a Stepper Motor Driver based on the L297 / L298 chipset.
