3D Printed GIFs For Stop Motion Memes

Lithophanes are nothing new, with examples going back to the 1800s. But they’ve become popular again thanks to the ease of which these pieces of artwork can be 3D printed. While the Internet would be more than happy to see somebody press an 3D image of their cat into a thin piece of translucent porcelain ready to have a light shone through it, that’s quite a bit harder than just firing up the Monoprice.

But since the machine is doing all the work for you, why stop at one? That’s precisely the sort of thinking that lead [The Mad Maker] to recreate animated GIFs with stop motion photography and a stack of printed lithophanes. Now all your favorite reaction memes can make the leap to the physical world…and then go right back into the computer.

The method here is pretty simple: [The Mad Maker] disassembles his favorite GIF to get the individual frame images, converts each one of those into a lithophane STL via an online tool, prints it out, photographs it, and then stitches all those photographs back into a new GIF. Given the incredibly time consuming nature of this process you’ll want to limit it to short animations, and even then, probably do only every 2nd or 3rd frame to preserve your sanity.

In the video after the break you can see the entire process, as well as check out the final result. While there weren’t really any technical hurdles to overcome in this project, we did like seeing how [The Mad Maker] experimented to find the ideal position for the backlight and camera. The wooden frame he came up with to hold everything in position should make subsequent meme conversions a lot easier, now he just needs to add a little color.

Low-Resolution Display Provides High-Nostalgia Animations

High-definition displays are the de facto standard today, and we’ve come to expect displays that show every pore, blemish, and bead of sweat on everything from phones to stadium-sized Jumbotrons. Despite this,  low-resolution displays continue to have a nostalgic charm all their own.

Take this 32 x 16 display, dubbed PixelTimes, for instance. [Dominic Buchstaller] has gone a step beyond his previous PixelTime, a minimalist weather clock and home hub built around the same P10 RGB matrix. The previous build was a little involved, though, with a nice wood frame that took some time and skill to create.

Building your own version of PixelTimes is really approachable. The case is mostly 3D-printed, and the acrylic parts [Dominic] laser cut could just as easily be cut with a saw. And that P10 board can be source for peanuts direct from Chine. The software for the project has been upgraded since the original version, supporting flicker-free animations. Everything runs on a NodeMCU, and there are even scripts to convert your favorite GIF to an animation. Oh, and it still displays the weather too.

This looks great and seems like a lot of fun, and [Dominic] kindly provides all the files you’ll need to build your own. It shouldn’t take more than an hour to build once you’ve got all the parts.

A Gif-Playing Top Hat For FRC 2018!

In gearing up to mentor a team at the 2018 FIRST Robotics Competition, redditor [dd0626] wanted to do something cool that resonated with this year’s 8-bit gaming theme. Over the course of a few days, they transformed a top hat into a thematically encapsulating marquee: a LED matrix display loaded with gifs!

The display is actually a sleeve — made from shipping foam, a pillow case, and an old t-shirt — that fits over the hat, leaving it intact and wearable for future events. A Teensy3.6 displays the gifs on four WS2812 16×16 RGB LED matrices, and while a sheer black fabric diffuses the light, it’s still best viewed from several feet away. This is decidedly not intended to be a stealthy hat display.

To mitigate current draw, [dd0626] is using a 5V 30A DC/DC converter and keeping the brightness at a minimum — otherwise, each panel can pull up to 15A! To offset any dip in performance, they’ve bundled in a massive 22,400mAh, 24V battery pack to keep the hat running for a while. Despite all the hardware, the hat weighs under two pounds — eminently wearable for a long day of competition. Continue reading “A Gif-Playing Top Hat For FRC 2018!”

Stunning Fake Polaroid Camera Performs Magic

It’s high time us Muggles got our hands on the hardware used to take Magical Photographs as seen in The Daily Prophet. The first pioneering step in that direction has been taken by [Abhishek] who built this moving picture taking polaroid-ish camera, which he’s calling the “Instagif NextStep”. It’s a camera that records a short, three second video, converts it to GIF and ejects a little cartridge which displays the animated photo.

This amazing piece of hardware has been painstakingly built, and the finished product looks great. The nice thing about building such projects, in [Abhishek]’s own words, is that “it involves a bunch of different skill sets and disciplines – hardware, software, 3D modeling, 3D printing, circuit design, mechanical/electrical engineering, design, fabrication etc that need to be integrated for it to work seamlessly.”

Animatronic Head Responds With Animated GIFs

[Abhishek] describes Peeqo as a “personal desktop robotic assistant” that looks like “the love child of an Amazon Echo and a Disney character.” We’re not sure about that last part — we’re pretty sure [Bender Bending Rodriquez] would fail a paternity suit on this one. Just look at that resemblance.

vkwnaidWhatever Peeqo’s parentage may be, it’s a pretty awesome build, and from the look of [Abhishek]’s design notes, he put a lot of thought into it, and a lot of work too. The build log reveals 3D-printed parts galore, custom-etched PC boards, and a hacked Raspberry Pi to both listen for voice commands and play responses in the form of animated GIFs on Peeqo’s ‘face’. The base has six modified RC servos to run the Gough-Stewart platform that lets Peeqo emote, and the head contains pretty much all the electronics. Beyond the hardware, a ton of programming went into giving Peeqo the ability to communicate through head gestures and GIFs that make sense for the required response.

Whether it’s bopping along to the tunes on your playlist or motivating you to lay off the social media with [Will Ferrell]’s flaming angry eyes, Peeqo looks like a ton of fun to build and use. Conveniently enough, [Abhishek] has shared all his files so you can build one too.

We haven’t seen anything like Peeqo before, but we have seen a lot of Amazon Echo hacks and even a few Stewart platform builds. But did we inadvertently feature a project starring Peeqo’s dad way back in 2009?

The Animated Gif Camera, Brought To You By A Raspberry Pi

No one watches video anymore. Cable cutters are digging into Verizon’s profits, and YouTube is a shadow of its 2005 self. What are people consuming now? Animated gifs. This is the bread and butter of the meme economy. Personally, all my investments are sunk deep into Gandolf / Balrog gifs, with each character replaced with Trump and Hillary. I expect a tidy profit on November 9th.

With animated gifs being the de facto method of sharing moving pictures, the world will belong to those who can create them. Phones are fine, but strangely video cameras, DSLRs, and other high-end photography equipment are the norm. This is idiotic, of course, because high-definition images are just a fad, and audio is useless.

Finally, there’s an answer. [Nick Brewer] created a camera that only takes animated gifs. I cannot stress this enough: this animated gif cam is a serious contender for a technical Oscar. Kubrick wept.

For the hardware, [Nick] went with a Raspberry Pi and Raspberry Pi camera. A combination of software ranging from PiCamera, GraphicsMagick, and GifCam turns this tiny bit of hardware into a machine dedicated to content creation in the hippest new medium. Other hardware includes a battery – either a normal LiPo ‘pouch’ cell, or an 18650 cell. Other hardware includes an Adafruit Powerboost 500 charge controller and a neat illuminated push button.

The 3D-printed enclosure is where this project really shines. Hearkening back to an older time, this camera includes a real viewfinder for all your gonzo giffing. The camera is charged through a completely normal USB port, and even the Pi’s SD card is accessible without disassembling the camera. There are even some paper wrappers for this camera to give it a 90s disposable camera aesthetic.

Of course, this isn’t the first camera dedicated to the creation of animated gifs. Before the C.H.I.P., Next Thing Co released OTTO, a camera designed for gifs. [Nick]’s project, though, is a camera dedicated completely to gifs. It is the greatest technical achievement of our time, for the creation of content in the greatest artistic medium.

Animated GIFs On A Graphing Calculator

The TI-84 Plus graphing calculator has a Z80 processor, 128 kilobytes of RAM, and a 96×64 resolution grayscale LCD. You might think a machine so lean would be incapable of playing video. You would be right. Animated GIFs, on the other hand, it can handle and [searx] is here to tell you how.

Before assembling his movie, [searx] first needed to grab some video and convert it to something the TI-84 could display. For this, he shot a video and used Premiere Pro to reduce the resolution to 95 by 63 pixels. These frames were saved as BMPs, converted to monochrome, renamed to pic0 through pic9, and uploaded to the calculator’s RAM.

To display the animated GIF, [searx] wrote a small program to cycle through the images one at a time. This program, like the images themselves, were uploaded to the calculator over the USB connector. Playing these animated GIFs is as simple as calling the program, telling it how fast to display the images, and standing back and watching a short flip-book animation on a calculator.
