Twisted Tea Launcher Refreshes At 104 MPH

A few weeks ago, a video went viral on social media that depicted a rather unsavory individual receiving what could be described as a “percussive reminder” of social norms courtesy of a bystander armed with a can of Twisted Tea. The video served as inspiration for many a meme, but perhaps none more technically intricate than this air cannon that launches 24 ounces of hard iced tea at better than 100 miles per hour built by [Greg Bejtlich].

It’s all fun and games until somebody brings out the weaponized bead seater.

Technically we’re looking at two different hacks here. The first is the pneumatic launcher put together using a low-cost eBay tire bead seater. These tools are designed to unleash a large volume of air into a tire so it can be properly seated onto the rim, but it doesn’t take much more than a few pieces of PVC pipe from the hardware store to turn it into an impromptu mortar. It’s even got a convenient trigger and a handle to help control the recoil. Though as you can see in the video after the break, it still ends up being a bit too energetic for [Greg] to keep a grip on.

For the projectiles, [Greg] has 3D printed a nose cone and tail fin that snap onto the 24 oz cans in hopes of making them more aerodynamically stable. The slow motion video seems to indicate they aren’t terribly effective, but they certainly look impressive. Spring-loaded control surfaces that deploy after the can leaves the muzzle could be the answer, though at some point you have to ask yourself how far you’re willing to go for an Internet meme.

It probably goes without saying that you definitely shouldn’t try firing cans of alcoholic iced tea off in your backyard. But the launcher itself might be useful for lofting antennas or hurling the occasional potato.

Hackaday Links: February 23, 2020

If you think your data rates suck, take pity on New Horizons. The space probe, which gave us lovely pictures of the hapless one-time planet Pluto after its 2015 flyby, continued to plunge and explore other, smaller objects in the Kuiper belt. In January of 2019, New Horizons zipped by Kuiper belt object Arrokoth and buffered its findings on the spacecraft’s solid-state data recorders. The probe has been dribbling data back to Earth ever since at the rate of 1 to 2 kilobits per second, and now we have enough of that data to piece together a story of how planets may have formed in the early solar system. The planetary science is fascinating, but for our money, getting a probe to narrowly miss a 35-kilometer long object at a range of 6.5 billion km all while traveling at 51,500 km/h is pretty impressive. And if as expected it takes until September to retrieve all the data from the event at a speed worse than dialup rates, it’ll be worth the wait.

Speaking of space, if you’re at all interested in big data, you might want to consider putting your skills to work in the search for extraterrestrial intelligence. The Berkeley SETI Research Center has been feeding data from the Green Bank Telescope and their Automated Planet Finder into the public archive of Breakthrough Listen, a 10-year, $100 million initiative to scan the million closest stars in our galaxy as well as the 100 nearest galaxies for signs of intelligent life. They’re asking for help to analyze the torrents of data they’re accumulating, specifically by developing software and algorithms to process the data. They’ve set up a site to walk you through the basics and get you started. If you’re handy with Python and have an interest in astronomy, you should check it out.

Staying with the space theme, what’s the best way to get kids interested in space and electronics? Why, by launching a satellite designed to meme its way across the heavens, of course. The Mission for Education and Multimedia Engagement satellite, or MEMESat-1, is being planned for a February 2021 launch. The 1U cubesat will serve as an amateur radio repeater and slow-scan TV (SSTV) beacon that will beam down memes donated to the project and stored on radiation-hardened flash storage. In all seriousness, this seems like a great way to engage the generation that elevated the meme to a modern art form in a STEM project they might otherwise show little interest in.

It looks as though Linux might be getting a big boost as the government of South Korea announced that they’re switching 3.3 million PCs from Windows to Linux. It’s tempting to blame Microsoft’s recent dropping of Windows 7 support for the defenestration, but this sounds like a plan that’s been in the works for a while. No official word on which distro will be selected for the 780 billion won ($655 million) effort, which is said to be driven by ballooning software license costs and a desire to get out from under Microsoft’s thumb.

And finally, in perhaps the ickiest auction ever held, the “Davos Collection” headed to the auction block this week in New York. The items offered were all collected from the 2018 World Economic Forum in Davos, Switzerland, where the world’s elites gather to determine the fate of the 99.999%. Every item in the collection, ranging from utensils and glassware used at the many lavish meals to “sanitary items” disposed of by the billionaires, and even hair and fluid samples swabbed from restrooms, potentially holds a genetic treasure trove in the form of the DNA it takes to be in the elite. Or at least that’s the theory. There’s a whole “Boys from Brazil” vibe here that we find disquieting, and we flatly refuse to see how an auction where a used paper cup is offered for $8,000 went, but if you’d like to virtually browse through the ostensibly valuable trash of oligarchs, check out the auction catalog.

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 a 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.

Hackaday Prize Entry: Memes

Snap, Inc., the company behind Snapchat, is branding itself as a hardware company. What hardware does Snap make? Spectacles, or a camera attached to a pair of sunglasses. Snap, Inc. has a market value of around $30 Billion USD.

For his Hackaday Prize entry, [William Glover] is building a device that’s easily worth $100 Billion. It’s called SnappCat, and it’s a machine learning, AI, augmented reality, buzzword-laden camera that adds memes to pictures of cats. Better get in on the Series A now because this is ????????????.

Here’s the use case for SnappCat. Place a small device containing a camera and some sort of WiFi chip. During the day, this device will take pictures. If the device recognizes your cat in a picture, it adds a meme (we assume this means text, probably using the Impact typeface), and sends it to your mobile device. Just imagine sitting in a meeting at work. Your phone buzzes, you look at the message, and you laugh uproariously. Yes, you can has fud Mr. Pibbles, you can has so much fud.

This is the height of technology. That’s not to say landing on the moon or building a civilization on Mars isn’t a superior technological achievement. SnappCat is simply the best technology humanity will every produce because it’s all downhill from here.

That said, this is a pretty interesting problem. A small, cheap device that does image recognition is hard, and adding memes is just the cherry on top. We can’t wait to see where this project goes, and it’s a great entry to the Best Product portion of the Hackaday Prize.

Nyan Cat

Embroidered Nyan Cat Brings A Meme To The Real World

Have you ever come across an Internet meme and just thought to yourself, “I have to bring this into the physical world!” Well [0xb3nn] and [Knit Knit] did. They decided to take the classic nyan cat meme and bring it to life.

The frame is 24″ x 36″. Many hours went into the knitting process, but the result obviously turned out very well. The stars include 24 LED sequins to add a sparkling animation effect. These were sewn onto the back of the work using conductive thread. They are bright enough to shine through to the front where needed. These connect back to an Arduino Pro Mini 5V board.

The Arduino is also connected to a capacitive touch sensor. This allows the user to simply place their hand over the nyan cat image to start the animation. No need for physical buttons or switches to take away from the visual design. An Adafruit AudioFX sound board was used to play back a saved nyan cat theme song over a couple of speakers. The source code for this project is available on github. Be sure to watch the demo video below. Continue reading “Embroidered Nyan Cat Brings A Meme To The Real World”

Meme Themed Pinball Machine – Much Flipping, Y U No Win?!

Summoning 4chans, 9gags, Reddits and other denizens of easily-digested content, Liberty Games stripped apart a dilapidated “Baby Doll” pinball arcade machine and turned it into this meme-spouting monstrosity. A complete redo of the vinyl and graphics to sport dozens of familiar internet tropes was first, then they had Shapeways create internal scenery and finally some electronics were added to spice things up.

We have seen PINMAME-based digital machines but this took a different path. Pinball machines this old pre-date common transistors so they rely on electro-mechanicals for everything. This made hacking the machine challenging so the team intercepted most of the signals and tied them into a Raspberry Pi with a Pi-face interface board. A videoscreen was added to the scoreboard, triggering all manner of memey videos and sounds according to actions performed and unlocked on the screen.

If you yearn for expired pranks of years gone by and are bad at pinball, you are in luck. Losing the game gets you Rickrolled – over and over again. On the plus side, Nyan Cat rockets away to bonuses and even the Admiral himself warns you of impending danger.

We resisted the urge to write this article as a chain of one meme to the next, you will get plenty of that from the well-documented project conversion and the following video. Someone in the comments will probably make a list of all memes.
