Hackaday Links: February 12, 2012

This is why digital picture frames were invented

[Petros] sent in this video of his visualization of Van Gogh’s Starry Night. He did this with openFrameworks and also made a version that reacts to sound. Is anyone else reminded of that one scene in Vincent and the Doctor?

A boat’s a boat, but a mystery box can be anything

[Rick] wanted to build a lock pick training station for the Eugene Maker Space, but he needed a way to make it interesting. What could be better than a mystery box? When you pick the deadbolt, open the box up and you’ll get a prize. Just make sure you put something of yours in the box for the next person.

3D printer prints its own case

Because the 3d printer community isn’t segmented enough, [Sublime] decided to design a new one. Here’s where it gets cool: the Tantillus can print its own case, and can ‘daisy chain’ to another Tantillus so only one set of electronics are needed. Interesting ideas afoot.

A diamond says I love you, but a duct tape rose says I’ll fix that for you

Valentine’s Day is coming up, so if you haven’t already made dinner reservations, you’re probably up the creek. How about making a duct tape rose for that special person in your life. Bonus: a dozen costs $3, and they won’t die in a week.

Using keypads over serial or SPI

[Leniwiec] sent in a tutorial on connecting keypads to a microcontroller with a serial or SPI interface. If you want to build a calculator, this is your chance. We’d use this for an Apollo Guidance Computer, though.


  1. +1 if you watched the whole starry night video! That was awexome ;-)

    The mystery box is also a very clever idea. Kind of like a geocache, without the GPS part.. hackercache?

    The starry night video was amazing!

    I feel like if Van Gogh could see this, he would approve.

    Nice links. Got to try the ducktape roses.

    Ah the romance of a rose that stinks like Duck/duct tape, and a Sharpie. ;)

    Wait, so do your valentines dates usually die a week after you give them flowers?

    I watched the whole starry night video. It was pretty awesome. I think it would look pretty cool running (on a loop) in a digital picture frame on a wall. Can the cheaper ones refresh fast enough for that kind of motion?
