[Aaron Shephard] at mini-itx.com just finished a backup DVD burning robot based on an EPIA M10000 Mini-ITX motherboard and scavenged parts. A Perl script interacts with stepper motors, LEDs, and sensors through the parallel port on the motherboard. The robot inserts DVDs for burning, flips them for labeling, and stacks completed discs in a pile. Coasters are rejected to a ‘penalty box’ for easy disposal.
We’ve also covered some other optical disc duplicators in the past.

VideoLAN just released VLC media player 0.9.2. VLC is probably the best known open source media player, and supports most audio/video formats without additional codecs. Before VLC, we usually installed buggy codec packs to watch videos in Winamp or Windows Media Player. We’ve found the nightly builds to be pretty stable for the past month, but it’s nice to see the final version released.
Download Squad gushed over the new interface design, but omitted the real change — VideoLAN switched from wxWidgets to the Qt toolkit. Among many changes, Qt allows video effects to be applied without restarting the media.
One of our favorite new features is an adjustments and effects menu for quick picture, sound, and subtitle tweaks. The new version has better support for flash videos (FLV), and will stream from most online video sharing sites. See the full changelog at the VideoLAN wiki, and help out if that’s your thing.

Electronics parts can be a pain to choose. It’s often hard to tell from manufacturers’ datasheets if a part will fit your design. We auditioned six different tactile switches to find a cheap button to use in upcoming projects. A tactile switch, also called a momentary button or push-to-make switch, is commonly used for input and microcontroller resets. This type of button creates a temporary electrical connection when pressed.
Footprints for most of these buttons are available in the Cadsoft Eagle library switch-tac, or in the Sparkfun parts library under TAC_SWITCH. Buttons in the image above are discussed from left to right. Continue reading “Parts: Tactile Switches For Your Next Project”
