Just in time for Valentine’s Day, here’s a project out of the LVL1 hackerspace in Louisville that should warm the heart of that special someone in your life. Behold the Magic 8 of Hearts.
The metaphors are somewhat mixed here, what with the heart-shaped box, the mysterious black window of a Magic 8-ball, and the cheesy once-a-year sayings like those printed on Sweethearts candies. [JAC_101] began surgery by punching a hole in the plastic heart for an OLED display. The white on black display evokes the Magic 8-Ball look, although adding a blue filter would have nailed it. A 3-axis accelerometer detects shaking motion and an Arduino Nano selects a message to display. Some white LEDs light up the enclosure and add a little pizzazz. As a bonus, the whole thing is inductively charged – no extra holes needed in this heart.
If your true love would appreciate something a little flashier, try this animated LED Valentine heart. And if you’re successful in your romantic endeavors, you might just find yourself building these ultra-geeky wedding invitations.

Our readers are most likely familiar with the ubiquitous “fortune” program that ships with many *nix distros, offering cheeky comments and quotes with the press of a button. [Nick] thought it would be cool to build a fortune telling machine using the app, resulting in the handsome device you see above.
The laser-cut wooden case is home to a Raspberry Pi which does the heavy lifting, a coin acceptor, an LCD screen for displaying the device’s status, along with a SparkFun thermal printer. Upon feeding the machine some money, the user can press the “Advise Me” button, prompting the RaspPi to present a printed fortune from its vast database of sayings. [Nick] took some time to do some rough categorization of the fortune databases, enabling the machine to offer more substantial content as the user inputs more coins.
Check out the video below to see [Nick’s] fortune telling machine in action.
