R2D2 Collects Valentine’s Cards Like A Boss

r2d2-valentines-card-box

Think back to your school days when each student would make a box which would receive Valentine’s cards from their friends. We have fond memories of buying cards with Teenage Mutant Ninja Turtles on them. We guess this tradition is still going strong. Instead of making a receptacle out of a shoe box  [Dr Franken Storer] helped his seven-year-old build this remote control R2D2 with sounds and lights. Yeah, it’s totally cheating. But who can begrudge a hacker dad a little fun?

The bot started as a desktop trash can. It features a domed top which looks just like the droid, but also has a hinged opening where the cards can be placed. To the lid he attached a tilt switch that triggers a Radio Shack sound player to provide the sounds. These sound modules are popular in a lot of projects like this doorbell hack. The final touch (aside from the droid decor on the outside) was to add a remote control car that lets his son drive R2 around.

We asked for more details and he delivered. You’ll find his lengthy description of the project after the jump.

Hackaday Links: Valentine’s Day, 2013

It’s not too late to hack your own Valentine’s day gifts. Here’s four projects to get you headed in the right direction.

Heart-shaped box

[Ian] built what he calls the Valentine’s gift bomb. It’s a cigar box with this LED heart on the top. A servo motor latches the lid from the inside and won’t open until the thing goes off on the big day. (sorry, no link to this one as he just sent us the pictures found after the break).

A Blinky Bouquet

[Ryan] shows us how to make a felt bouquet and then light things up with some LEDs.

Pictures in a bottle

Reuse that old incandescent bulb by adding LEDs and heart-shaped pictures inside the glass enclosure.

Robot love

This cocoa container turned robot cat calls, raises its eyebrows, and blinks the LEDs eyes when she presses the button on top.

Happy Late Lit Acrylic Valentines Day

Although [Danman] was right on time with his home-hacked Valentines day gift, this article comes to you a little late. With the message on the heart changed, however, it could be a perfect “Sorry I forgot Valentines Day again” gift, so it may still be useful.

The concept isn’t that complicated, simply a strip of LED lights around a piece of acrylic. A battery holder and switch rounds out this build. It’s a neat way to light things up, but what we thought was especially interesting was the way it was engraved and cut out with a minimum of traditional tools.

Sure, [Danman] had access to a bandsaw, but as for actually engraving the outline he used a modified electric toothbrush! We’d love to see that build written up. If that wasn’t enough, the lettering was “ghetto blasted”, as he puts it, using a compressed air nozzle, a pen tube, and a styrofoam cup full of ceramic dust! Macgyver would be proud!
