it's tetris, in an altoids tin!
inside is an Arduino chip on a custom pcb that connects it to this LCD ($1 from sparkfun, talks over SPI) and four buttons. rotation works properly, collision detection seems to work fine, etc.
the eagle files are on randomskk.net/projects/arduino_tetris while the code is on github.com/randomskk/arduino_tetris (note that it's designed to be compiled from a makefile but you can strip out the WProgram and main() function at the end to make it compile from the arduino IDE)

Bits and bobs
Pictures taken during exercising my hobby (electronics) and building/disassembling amplifiers and/or upgrading a record player tonearm and pre-amplifier. Anyway, a text was needed, to describe this lot, and here it is (the text and the lot, enjoy the pictures :)).

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.
At long last, after way too much procrastination, I have finished setting up my home electronics workbench. I used to work on a tiny folding table in the middle of the room with about two feet by two feet of empty space, and my parts cabinets on the floor on the other side of the room. This is much better.
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

Erin, I've fully joined the dark side.
My uncle's friend is a photographer, and she lends her extra cameras to "young photographers" such as myself. xD THANKS KRIS (:
Part of my Polargraph re-build:
Had to swap out my old diecimilia, the ATMega168 wasn't big enough. I need to get a new chip for it.
The driver chips get warm but not too hot with my current motors. I was going to heat sink them, but haven't had to yet. Once I have the hardware ironed out I'll neaten up the wiring and print out a holder for the electronics that clips to the top of the drawing board.

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.
Labu sayong is a type of earthenware jar that certain Perak Malays used for the storage of drinking water. The glossy, black labu sayong is a state icon for Perak. Instantly recognisable, labu sayong takes days of handwork in forming, firing, drying and engraving. The gourd-shaped jars made of fine clay are carbonised using hot rice husk to give them that black gloss. Only river pebbles are used to polish the outer surface of the jar.
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!
