A Lot Of Love Went Into This Glowing Valentine

February 15, 2012 by Mike Szczys 12 Comments

[Will] didn’t pick up a card, rose, and bottle of wine for Valentine’s Day like most guys. Nope, he planned way ahead and built this color-selectable glowing Valentine. When we first saw it, we figured he threw some LEDs together with a microcontroller and edge-lit a piece of acrylic. While that is technically what happened, there was a lot more design and craftsmanship at play here than you might think.

First off, the controller board is a beautifully designed two-sided PCB which he etched rather than throwing a mess of wires and hot glue into an enclosure. Speaking of enclosures, he grabbed a wooden picture box from the big box store and used a piece of brass plate stock to serve as the control panel. The enclosure was finished with tinted polyurethane after having a slit added to the top for the acrylic. The message itself was milled using an engraving bit and a Dremel tool. This was done by hand and we think achieves a finished look that is comparable to the CNC milled ornaments we’ve seen in the past.

Get a good look at the device and a demonstration of its features in the clip after the jump.

Tears From Your Lonely Heart Will Activate A Comforting Tune

February 14, 2012 by Mike Szczys 7 Comments

If you’re forever alone we’d guess you’ve long since stopped crying about it. But if you’re still prone to shed a tear on a dateless Valentine’s day this project’s for you. [Mikeasaurus] spruced up this pillow to play a tune when it senses your lonely soul. It’s got a moisture sensor which triggers an audio greeting card just when your weeping really starts to get soggy.

If you look closely at the top portion of the white fabric in the picture you can see there are rows of stitching. These hold a matrix of conductive wire mesh fabric on the inside of the pillow case. There are two buses made up of alternating rows (think of the tines of two forks pointed together) which make up the probes. When the gap is bridged by moisture a transistor circuit triggers the audio bits from a greeting card to play a song. Check out the demo after the break. We’re not satisfied that [Mikeasaurs’] couldn’t even bring himself to cry real tears for the clip, but maybe years of solder fumes have clogged up those tear ducts.

Disco Icosahedron Rings In The New Year

December 31, 2011 by Brian Benchoff 2 Comments

While city engineers were setting up the multicolored ball of lights in Times Square this year, [Phil] at adafruit was busy designing the X2 Time Ball, a disco icosahedron perfect for celebrating the new year.

The ball is made of 20 acrylic triangles zip-tied together into an icosahedron. On each face, six RGB pixels light up via commands from an Arduino. The entire project is able to be controlled remotely thanks to the help of a pair of XBees. [Phil] whipped up a Processing sketch to control the LED ball any way we could possibly imagine.

Although it may be a little late to build an LED disco ball for this year’s New Year’s Eve party, that doesn’t mean we couldn’t use it the other 364 days of the year. It’s perfect for parties, weddings, and our weekly lightswitch raves. Check out the action video of the Time Ball after the break.

Doomsday Keg Of Radness Helps Ring In The New Year

December 30, 2011 by Mike Nathan 3 Comments

doomsday-keg

Lots of people buy noise makers for New Year’s eve, others opt to sing Auld Lang Syne – then there’s these guys.

The crew at Stone Brewing Company throw an annual bash at their brewery in celebration of New Years, and while [Dino’s] countdown timer is great for intimate settings, they needed something bigger to wow the crowd. A busted half barrel was all the inspiration they needed to build the “Doomsday Keg of Radness”.

[Mike Palmer], the Creative Director at Stone handed the keg off to the maintenance crew for some remodeling, and got ready to fit it with all sorts of lights and other goodies. Holes drilled in the keg were fitted with bright pulsing LEDs, while additional LED light strips were laid out around the perimeter. The bottom was cut out to accommodate a Moonflower LED module, and a 24” monitor was strapped to the side in order to display a countdown timer. An old Macbook jammed inside the keg runs the video display, while the rest of the lighting is remotely controlled with an RF transmitter.

Now mind you this all went down last year, but since the display was such a hit, they will be busting it out again for the 2011 celebration.

Check out the short demo video below to get a look at the Doomsday Keg in action.

Build Your Own Mini Ball Drop For New Year’s Eve

December 30, 2011 by Mike Nathan 6 Comments

[Dino] wanted to make this New Year’s celebration a bit more interesting, but he can’t make it to New York for the ball drop. Instead, he decided to make his own mini display in his workshop. Obviously he’s working with a slightly smaller budget than the folks at Times Square, but we think his display is pretty neat. If anything, [Dino] can at least guarantee that his New Year’s is 100% Seacrest-free.

The ball drop is made up of five ping pong balls, each backlit by a 10mm LED. The LEDs and ping pong balls were mounted on the electron gun from a broken oscilloscope, giving it a cool look. The balls are lit one at a time by an Arduino, which illuminates each one for 15 seconds while the final minute of 2011 is counted down. Once midnight hits, a flashing “2012” sign illuminates while Auld Lang Syne plays from a tiny speaker.

The musical part of this build is something that [Dino] spent a lot of time on. He thoroughly explains how he translated the song from sheet music into its digital form, a process that would be helpful for beginners to watch.

Continue reading to see how the display was built, and if you’re just antsy to see the ball drop in action, a short demo can be found at 12:13.

Keeping Christmas Present Hunters Guessing With QR Code Gift Tags

December 22, 2011 by Mike Nathan 31 Comments

qr-code-gift-tags

[Thadd Brooks] is a geeky dad of the highest degree. His kids are constantly trying to figure out what mom and dad bought them for Christmas, while he continues to think up ways to stymie their progress. He certainly could have put a few prank presents under the tree, but he opted to go a different route, confusing his smartphone-wielding kids with QR codes.

Each gift under the tree bears no name tag, rather they are adorned with a single QR code sticker which [Thadd] printed out. When scanned, the code brings his children to a page on his web server stating who the gift is for.

The catch? Well, the codes bring up a random page each time, attributing the gift to every member of the family along the way. There’s no chance that any of the kids will be able to correctly identify their gifts before Christmas Eve, when [Thadd] flips a switch on the server and reveals the actual gift recipients.

It’s certainly a clever, yet frustrating, way to keep his family on their toes, and we think it’s a pretty awesome idea.

Tannenbaum Ticker, Even Though The Markets Close For Christmas

December 22, 2011 by Brian Benchoff 6 Comments

Maybe we’re a little bitter because we held on to our pumpkin futures well into November, but we’ve got to respect [Nick]’s stock ticker ornament. It’s an Internet-connected Christmas ornament that queries stock prices and displays the change with an RGB LED.

The build uses a Propeller Platform USB and the Propeller E-Net Module to pull stock quotes down from Google. With the attached source, selecting any traded company is easy enough; all that’s needed is to select a company is changing a line in the code. The Propeller pulls the quote every 30 seconds during the trading day, and parses it into a ‘percent changed’ format. The ornament glows red if the change is more than a 4% negative change, green for within 0.2% of open, and blue if more than a 4% positive change.

[Nick] is more of a ‘set it and forget it’ investor, so this ornament is a handy, passive way to keep an eye on his investments. Check out the demo vid after the break.
