The Blackest Black, Now In Handy Pocket Size

If you thought “carbon nanotubes” were just some near-future unobtainium used in space elevators, don’t worry, you certainly aren’t alone. In reality, while the technology still has a way to go, carbon nanotube production has already exceeded several thousand tons per year and there are products you can buy today that are using this decidedly futuristic wonder material. Now there’s even one you can put in your pocket.

Created by [Simon], a designer in the UK, this small carbon nanotube array is described as “A simulated black hole” because the surface absorbs 99.9% of the visible light that hits it. Protected by a clear acrylic case, the sample of the material makes a circle that’s so black it gives the impression you’re looking into deep space. Unfortunately, no time-dilating gravitational forces are included at any of level of support in the ongoing Kickstarter campaign; but considering it was 100% funded in just a few hours, it seems like most people are OK with the trade-off.

[Simon] is well aware of the ongoing war between different methods of creating the “Blackest Black”, and he thinks he’s put his money (and by extension, his backer’s) money on the winner. Singularity is using a similar technology to the exclusively-licensed Vantablack, rather than a super-dark paint like “Black 3.0”. In fact he’s so confident that Singularity will appear darker than Black 3.0 that he mentions a head-to-head comparison is currently in the works.

If there’s a downside to the carbon nanotube array used in Singularity, it’s that you can’t actually touch it. [Simon] warns that while the acrylic case is only held together with magnets and can be opened for more careful inspection, actually touching the surface is absolutely not recommended. He says that even dust getting on the material is going to adversely effect its ability to absorb light, so you should really keep it buttoned up as much as possible.

While the Singularity looks like an interesting way to experience near perfect blackness, the concept itself is far from a novelty. A material that can absorb essentially all the light that hits it has important scientific, military, and of course artistic applications; so figuring out how to pull it off has become a pretty big deal.

This Is A Kickstarter For None More Black

Vantablack is the darkest pigment ever created, capable of absorbing 99.96% of visible light. If you cover something in Vantablack, it turns into a black hole. No detail is presented, and physical objects become silhouettes. Objects covered in Vantablack are outside the human experience. The mammalian mind cannot comprehend a Vantablack object.

Vantablack is cool, but it’s also expensive. It’s also exclusively licensed by [Anish Kapoor]’s studio for artistic use. Understandably, artists have rebelled, and they’re making their own Vantablack-like pigments. Now, the World’s Blackest Black is on Kickstarter. You can get a 150 ml bottle of Black 3.0, something that’s almost black as Vantablack, for £10.

Is this a photoshop? Who knows.

The pigment for Black 3.0 is called Black Magick, and yes, there was a version 2.0 The problem with the earlier version is that although the pigment was blacker than almost anything else, paint isn’t just pigment. You need binders. The new formulation uses a new acrylic polymer to hold the pigment, and ‘nano-mattifiers’ to make the paint none more matte.

What can you do with the blackest black paint you’ve ever seen? Well, taking pictures of an object covered in the blackest black is a tiny bit dumb. This is something that must be experienced in person. You could paint a car with it, which is something I really want to see. You could follow [Anish Kapoor] around in the shadows. Use it as a calibration target. Who knows what we’ll do with the almost-Vantablack when everyone has it.

FIDO2 Authentication In All The Colors

Here at Hackaday, we have a soft spot for security dongles. When a new two-factor-authentication dongle is open source, uses USB and NFC, and supports FIDO2, the newest 2FA standard, we take notice. That just happens to be exactly what [Conor Patrick] is funding on Kickstarter.

We’ve looked at [Conor]’s first generation hardware key, and the process of going from design to physical product.  With that track record, the Solo security key promises to be more than the vaporware that plagues crowdfunding services.

Another player, Yubikey, has also recently announced a new product that supports FIDO2 and NFC. While Yubikey has stepped away from their early open source policy, Solo is embracing the open source ethos. The Kickstarter promises the release of both the software and hardware design as fully open, using MIT and CC BY-SA licenses.

For more information, see the blog post detailing the project goals and initial design process.  As always, caveat emptor, but this seems to be a crowdfunding project worth taking a look at.

Hackaday Links: October 14, 2018

Here’s something of interest of 3D printing enthusiasts. How do you print lightweight 3D objects? [Tom Stanton] does a lot of stuff with 3D printing and RC airplanes, so yeah, he’s probably the guy you want to talk to. His solution is Simplify3D, printing two layers for whatever nozzle diameter you have, some skills with Fusion360, and some interesting design features that include integrated ribs.

Moog released their first polyphonic analog synth in 35 years. It’s massive, and it costs eight thousand dollars.

There’s a RISC-V contest, sponsored by Google, Antmicro, and Microchip. The goal is to encourage designers to create innovative FPGA and soft CPU implementations with the RISC-V ISA. There are four categories, the smallest implementation for SpartFusion2 or IGLOO2 boards, and the smallest implementation that fits on an iCE40 UltraPlus board. The two additional categories are the highest performance implementation for these boards. The prize is $6k.

” I heard about polarization filters and now I’m getting a hundred thousand dollars” — some moron. IRL Glasses are glasses that block screens. When you wear them, you can’t watch TV. This is great, as now all advertising is on TVs for some inexplicable reason, and gives these people an excuse to use frames from John Carpenter’s masterpiece They Live in their Kickstarter campaign. Question time: why don’t all polarized sunglasses do this. Because there’s a difference between linear and circular polarized lenses. Question: there have been linear polarized sunglasses sitting in the trash since the release of James Cameron’s Avatar. Why now? No idea.

Alexa is on the ESP32. Espressif released their Alexa SDK that supports conversations, music and audio serivces (Alexa, play Despacito), and alarms. The supported hardware is physically quite large, but it can be extended to other ESP32-based platforms that have SPI RAM.

The Tiniest Computer Vision Platform Just Got Better

The future, if you believe the ad copy, is a world filled with cameras backed by intelligence, neural nets, and computer vision. Despite the hype, this may actually turn out to be true: drones are getting intelligent cameras, self-driving cars are loaded with them, and in any event it makes a great toy.

That’s what makes this Kickstarter so exciting. It’s a camera module, yes, but there are also some smarts behind it. The OpenMV is a MicroPython-powered machine vision camera that gives your project the power of computer vision without the need to haul a laptop or GPU along for the ride.

The OpenMV actually got its start as a Hackaday Prize entry focused on one simple idea. There are cheap camera modules everywhere, so why not attach a processor to that camera that allows for on-board image processing? The first version of the OpenMV could do face detection at 25 fps, color detection at more than 30 fps, and became the basis for hundreds of different robots loaded up with computer vision.

This crowdfunding campaign is financing the latest version of the OpenMV camera, and there are a lot of changes. The camera module is now removable, meaning the OpenMV now supports global shutter and thermal vision in addition to the usual color/rolling shutter sensor. Since this camera has a faster microcontroller, this latest version can support multi-blob color tracking at 80 fps. With the addition of a FLIR Lepton sensor, this camera does thermal sensing, and thanks to a new library, the OpenMV also does number detection with the help of neural networks.

We’ve seen a lot of builds using the OpenMV camera, and it’s getting ot the point where you can’t compete in an autonomous car race without this hardware. This new version has all the bells and whistles, making it one of the best ways we’ve seen to add computer vision to any hardware project.

Join Hackaday For A Night Of Pre-Maker Faire Hacks

This weekend is the World Maker Faire in New York, and Hackaday will be there looking at the latest and greatest projects from makers around the globe. We’ll also be buying bottles of water for five dollars, but that’s another story entirely.

As always, this year’s World Maker Faire will be held at the wonderful New York Hall of Science, and the lineup is spectacular. There will be cosplay, and Adam Savage will be there with a half dozen Junior Mythbusters. There will be a twenty-six foot tall hydraulic hand trucked in from Burning Man. You’re looking at the greatest event in STEAM education since the Bay Area Maker Faire last May.

Hackaday has a fantastic New York community and we’re holding a meetup this Thursday to sync up with Maker Faire. Guess what?  You’re invited!

We’re teaming up with our friends at Kickstarter to bring you an awesome night of hardware builds, music hacks, snacks, and more. While this is an informal event, we do have a few people who will be bringing their latest hacks to show off. Nick Chelyapov, a designer turned gear head who designed an Arduino-based synthesizer and drum machine. This isn’t a toy, but it’s also not a complicated mess of patch cables and eurorack modules. The Bitty is a real instrument that’s easy enough for anyone to pick up and make bleep bloops.

Also confirmed for this meetup is Nick Yulman, an artist who works with sound and interactive media in a variety of contexts. He’s gearing up to install his robotic musical instruments in the Areté Gallery in Greenpoint, Brooklyn. But this week he’ll be showing us how musical robots helped him stop worrying and love digital music.

This isn’t an event to be missed. You can RSVP for the event over on Eventbrite, and be sure to bring whatever project you’re working on. It’s going to be an entire night of drinks and hacks, just the thing before Maker Faire really gets rolling. Once the weekend hits, find us at the Faire; several of us from the Hackaday crew will be wandering the grounds looking for awesome hardware projects. Stephen Tranovich is even giving a talk about the Hackaday Prize on Sunday at 11. See you at the Faire!

The Desktop Computer Returns As Amiga-Infused Retro Case

The desktop computer is dead. No, I don’t mean computers that are meant to sit either on or underneath a desk. I’m talking about computer cases that are placed on a desk horizontally, probably with a monitor on top. The ‘monitor stand case’ was a mainstay for most of the 80s and 90s, but died out when CRTs became too heavy.

Now, though, there’s an interesting Kickstarter project that aims to bring the desktop computer case back, and it’s doing it as an upgrade to the classic Amiga 500, Amiga 1200, and Amiga 600 computers.

The idea for this project began all the way back in the 80s, with the Checkmate A1500 computer case. This case was designed to add expansion capabilities to the low-end Amiga 500 computer, transforming it into a desktop system with extra floppies, a hard drive, and an expansion port. In effect, you could have a ‘professional’ Amiga system for half the price of Commodore’s product offerings.

Now the Checkmate is back, this time with a case upgrade that will transform an A500, A600, A1200, or even the PPC Aeon Tabor A1222 motherboard. There’s another trick this case has to offer: it’s also compatible with MicroATX and Mini-ITX motherboards, meaning yes, there is now going to be a real desktop case that you can throw a motherboard in and a monitor on top.

The death of the desktop computer is an absolutely tragic tale that has resulted in people dropping towers on a floor and propping up their LCDs on piles of books. The reason why we do this is understandable — when CRTs got too heavy for plastic enclosures, computers became towers. Now, though, we’re all using featherweight LCDs, and computers could easily return to the desktop.
