Homemade Robotic Xylophone Plays Holiday Melodies
compumike writes "Just in time to add a bit of geeky holiday cheer to your office, this video demonstrates how to build a robotic xylophone featuring handmade solenoids and aluminum bars, and shows it playing several classic holiday tunes. New songs can be programmed in with C macros, and this project could even be extended to perhaps play a melody when a new e-mail arrived or a software build has finished compiling!" -
Google Voice Controls Giant LED Display
compumike writes "What geek among us has never thought about how cool it would be if you could call your computer and have it do stuff? Josh Davis put together a quick video demo and source code of his Voice Controlled LED Marquee, powered by Google Voice speech recognition and a DIY LED Array Kit. Imagine using the same display for monitoring server uptime, or RSS feeds!" -

DIY Microprocessor Sound Level Meter Demoed At MIT
An anonymous reader writes "A Piezoelectric Sound Level Meter was demoed at MIT's Battle of the Bands last month, borrowing its display from the do-it-yourself USB LED marquee that was the subject of a previous Slashdot story. This video tutorial describes in detail both the analog electronics plus the C code that runs the system. If this is your first experience at the intersection of digital and analog systems, don't be scared!" -
Hackable Microcontroller-Powered Valentine's Card
compumike writes "If you have a significant other to impress this Valentine's Day, consider putting your programming skills to use. This video tutorial shows how to build an LED Heart Valentine's card, powered by a microcontroller running C code, with a neat randomized 'twinkling' effect in an interrupt handler. Think about it: how many ladies can say that their Valentine's card runs at 14 MHz?" -
DIY LED Array Marquee For Your PC
An anonymous reader writes "Ever wish you had one of those big LED displays to keep you up to date on e-mails, stock quotes, server uptimes, or weather? Here's a new video tutorial showing how to build your own computer-controlled LED array. You can code your own data feed, and just send it over a TCP socket. This looks like a fun weekend project for someone looking to get started with electronics by building something useful." -
DIY USB Servo-Guided Water Gun
An anonymous reader writes "What better way is there to learn something than by making your own DIY gadget? Here's a new video showing how to use a common hobby servo, in conjunction with a small water pump, to create a USB controlled water gun! You can use your keyboard to aim and fire at an unsuspecting passerby. Both fun and educational, this project looks like a great DIY weekend project for any IT guy, wanting to make sure people think twice before asking a stupid question!" -
DIY iPhone-Controlled R/C Car
An anonymous reader writes "NerdKits has an example of their latest project, an iPhone-controlled R/C car running around Boston and MIT. Technical details, build-it-yourself instructions, and a video of the car in action are all included."
