In a somewhat ironic chain of events, uTorrent alpha for Mac has been leaked on Pirate Bay. Initial reviews are positive, with some saying that it runs better than its windows counterpart. The search function seems to be broken though.

Both Canon and Nikon recently released DSLR cameras that now include a feature that most consumer level digital cameras have had for sometime: the ability to record movies. What makes movie recording especially appealing on a DSLR is the wide selection of lenses available to get the look you’re after. If you’re an owner of Canon’s 40D you may want to follow [DataGhost]’s progress on the CHDK forum as he is currently working on bringing this function to the 40D.
While [DataGhost] has a working proof of concept he notes that there are still some issues pertaining to the camera powering down while recording a video, autofocusing, and writing to the memory card. Aside from this, [DataGhost] has made considerable progress and is considering adding custom user settings via the mode dial to really give some creative control. We’re excited about this hack and can’t wait for its release to the general public.

[Perry’s] awesome AcceLED Pong project gives new life to a classic game by adding acceleration-based control. The pong paddles are moved by tilting the circuit left or right. Motion is measured by an ADXL203 dual axis accelerometer, and an ATMEGA32 microcontroller converts acceleration into ball and paddle movement. The game display is a three-color SparkFun 8×8 LED matrix with serial interface.
[Perry] also used a similar setup to make a USB LED spectrum analyzer fed by the Linux XMMS media player.
We’ve seen our fair share of home made arcade machines, some complex and some simple. This one stands head and shoulders above the rest with its ability to combine two of our deepest loves: beer and video games. There’s not a lot of information, just a few pictures. We’d love to see some build shots or action shots. We’d love to test it out actually.
Here’s an update: [Burke LaShell] is the maker of this fine project. You can see more pictures of it in this thread. Thanks, [Shawn].

[shakirfm] sent us this LED persistence of vision (POV) laser projector that can display dot matrix style text. The laser projector contains a rotating mirror assembly and 5 lasers. We’ve covered other POV projectors,but this one is a bit different. The mirror assembly rotates using two cooling fans. Controlling on/off times of the lasers along with the mirror speed, it is able to project 8×5 dot matrix ASCII text onto a surface.

[Alpay Kasal] of LitStudios as come up with an interesting way to use laser pointers as a wireless controller for games and applications. The process is currently being patented, which may explain why [Alpay]’s blog is a little slim in the details. We doubt they’re doing anything more than just using a camera to track the laser pointer; exactly like laser tagging.
If you’re just itching to get your hands on some wireless game play and can’t wait for this to go commercial you could always just get a Nintendo Wii.

Every project needs a power supply. As 3.3volt logic replaces 5volt systems, we’re reaching for the LM317 adjustable voltage regulator, rather than the classic 7805. We’ve found four different hobbyist-friendly packages for different situations.
A simple voltage divider (R1,R2) sets the LM317 output between 1.25volts and 37volts; use this handy LM317 calculator to find resistor values. The regulator does its best to maintain 1.25volts on the adjust pin (ADJ), and converts any excess voltage to heat. Not all packages are the same. Choose a part that can supply enough current for your project, but make sure the package has sufficient heat dissipation properties to burn off the difference between the input and output voltages.
