Walkman-esque Human Interface Device

October 26, 2014 by Bryan Cockfield 15 Comments

Cheap keyboards never come with extra buttons, and for [Pengu MC] this was simply unacceptable. Rather than go out and buy a nice keyboard, a microcontroller was found in the parts drawer and put to work building this USB multimedia button human interface device that has the added bonus of looking like an old-school Walkman.

The functions that [Pengu MC] wants don’t require their own drivers. All of the buttons on this device are part of the USB standard for keyboards: reverse, forward, play/pause, and volume. This simplifies the software side quite a bit, but [Pengu MC] still wrote his own HID descriptors, tied all of the buttons to the microcontroller, and put it in a custom-printed enclosure.

If you’re looking to build your own similar device, the Arduino Leonardo, Micro, or Due have this functionality built in, since the USB controller is integrated on the chip with everything else. Some of the older Arduinos can be programmed to do the same thing as well! And, with any of these projects, you can emulate any keypress that is available, not just the multimedia buttons.

The Traveling Terabyte Project – Helping Those Who Protect Us

Though some people differ on what exactly a “hacker” is, there is one thing that can be said for certain – this global community of tinkerers, experimenters, and hobbyists we belong to is one of big hearts. Through our various projects and tutorials, we lead by example – sharing knowledge and offering help whenever we can. You would be hard pressed to find something that could exemplify this more than the Traveling Terabyte Project.

Started in the summer of 2006 by [Deviant Ollam], the goal of the project was to provide informational content from DefCon 14 to those friends and acquaintances who were deployed overseas in the service of the U.S. Armed Forces and their associates. This was originally done by outfitting durable cases with large portable hard drives stuffed with movies, music, and publications in order help those stationed far from their friends and family enjoy their down time a little bit more.

The project has grown by leaps and bounds while the storage mediums have shrunk accordingly. The project has recently entered a new phase, where they are migrating over to flash drives instead of hard drives, which should help spread the distribution of media immensely.

The Traveling Terabyte Project did not approach us soliciting money or publicity in any way, so by no means should you feel obligated to support the project. Regardless of our individual political leanings and views on war, we believe that helping out people who are subject to extreme amounts of stress while stationed far away from their home, friends, and family is a noble cause.

Bluetooth Multimedia Remote

August 5, 2010 by Mike Szczys 17 Comments

[Mathieu] spent three months developing this multimedia remote control. It connects to a PC via USB or Bluetooth and communicates with Winamp to pull down track information for display on a Nokia LCD screen. It can also be used as a wireless headset via the two on-board jacks. [Mettieu] thinks it’s just a small hop away from working as a Skype client if you take the time to write a plugin for that API.

VLC Media Player 0.9.2 Released

September 16, 2008 by Ian 14 Comments

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.
