ICub Is The Robot That Is Equally Cute And Creepy

September 16, 2018 by 13 Comments

We shouldn’t say iCub — the humanoid robot from Italy — is creepy. After all, human-like robots are in their infancy and an early computer or automobile would hardly be indicative of where those industries would take us. You can see the little guy in the video below.

The effort is open source and was part of an EU project that has been adopted by 20 labs around the world. The video just shows a guy in VR gear operating the robot, but the website has a lot of technical information if you want to know more.

Hackaday Links: September 16, 2018

Apple released a phone, the most phone in the history of phones. It’s incredible.

There are four machines that are the cornerstone of electronic music. The TR-808, the TR-909, the TB-303, and the SH-101 are the machines that created techno, house, and every other genre of electronic music. This week at KnobCon Behringer, the brand famous for cheap mixers, other audio paraphernalia of questionable quality, and a clone of the Minimoog, teased their clone of the 909. Unlike the Roland reissue, this is a full-sized 909, much like Behringer’s clone of the 808. Price is said to be under $400, and the best guess on the release is, ‘sometime in the next year’

Speaking of synths, [jan] has created a ton of electronic musical instruments based around single chips. There’s one that fits inside a MIDI plug, and another that also adds a keyboard. Now he has an ‘educational kit’ on IndieGoGo. It’s surprisingly cheap at $19.

Europe, currently.

Europe is outlawing memes (I’m 12 and what is this?).

The EU parliament adopted a proposal for a Copyright Directive, the most onerous proposal being Article 13, requiring platforms to adopt copyright filters to examine everything uploaded to a platform.

The takeaway analogy is that this proposal is opposite of the DMCA’s Safe Harbor provision that protects ISPs from consequences of user’s actions; If Article 13 is adopted, an image-hosting service could be sued by copyright holders because users uploaded copyrighted images.

Needless to say, this is dumb, and a massive opportunity for you to become a startup founder. Companies like Google and Facebook already have robots and databases crawling their servers looking for copyrighted content, but smaller sites (hackaday.io included) do not have the resources to build such a service themselves. You’re looking at a massive B2B startup opportunity when these copyright directives pass.

Turn Yourself Into A Cyborg With Neural Nets

If smartwatches and tiny Bluetooth earbuds are any indications, the future is with wearable electronics. This brings up a problem: developing wearable electronics isn’t as simple as building a device that’s meant to sit on a shelf. No, wearable electronics move, they stretch, people jump, kick, punch, and sweat. If you’re prototyping wearable electronics, it might be a good idea to build a Smart Internet of Things Wearable development board. That’s exactly what [Dave] did for his Hackaday Prize entry, and it’s really, really fantastic.

[Dave]’s BodiHub is an outgrowth of his entry into last year’s Hackaday Prize. While the project might not look like much, that’s kind of the point; [Dave]’s previous projects involved shrinking thousands of dollars worth of equipment down to a tiny board that can read muscle signals. This project takes that idea a bit further by creating a board that’s wearable, has support for battery charging, and makes prototyping with wearable electronics easy.

You might be asking what you can do with a board like this. For that, [David] suggests a few projects like boxing gloves that talk to each other, or tell you how much force you’re punching something with. Alternatively, you could read body movements and synchronize a LED light show to a dance performance. It can go further than that, though, because [David] built a mesh network logistics tracking system that uses an augmented reality interface. This was actually demoed at TechCrunch Disrupt NY, and the audience was wowed. You can check out the video of that demo here.

This Nearly NIMO Clock Fakes It And Makes It

September 16, 2018 by 12 Comments

Pity the aficionado of rare vintage displays. While Nixies and VFD tubes get all the attention and benefit from a thriving market to satisfy demand, the rarer displays from the mid-20th century period are getting harder and harder to find. One copy of an especially rare display is hard enough to find. Six copies for a clock? That’s a tall order.

That doesn’t mean you can’t fudge it, though, which is how this faux-NIMO clock came to be. [Paul Bricmont] was inspired by [Fran Blanche]’s NIMO tube primer, wherein the rare, single-digit CRT display was put through its paces. We’ve got to admit, it’s an easy display to fall in love with, thanks to its eerie blue phosphor glow, high voltage supply, and general quirkiness. [Paul] was unable to lay hands on a single tube, though, so he faked it with six tiny TFT displays and some plastic lenses. The lenses mimic the curved front glass of the original NIMO, while the TFT displays provide the stencil-style images of each numeral. The phosphor glow comes from replacing the stock white TFT backlight with a Neopixel array that can produce just the right shade of blue-green. 3D-printed modules hold two digits each, and the usual Arduino components run the show. The effect is quite convincing, although we bet some software tweaks could add things like faux burn-in and perhaps soften the edges of the digits to really sell it.

What other rare displays could be replicated this way? Given the variety of displays that were tried in the pre-LED era, it may be a rich vein to mine.

This Xbox 360 Is Powered By Steam

September 16, 2018 by 43 Comments

Now that we’re far enough into the next generation of home video game consoles that we can’t really keep calling them that anymore, yard sales are sure to be full of lonely Xbox 360s and PS3s that have been put out to pasture. You’ll probably even find a Wii U or two out there that somebody accidentally purchased. This is great for hackers who like cramming new electronics into outdated consumer gear, and accordingly, we’re starting to see the fruits of that generational shift.

Case in point, this Xbox 360 which has been transformed into a “Steam Box” by [Pedro Mateus]. He figured the Xbox 360 was the proper size to fit a full PC plus PSU, while still looking contemporary enough that it won’t seem out of place in the entertainment center. Running SteamOS on Fedora 28, it even offers a traditional game console experience and user interface, despite the decidedly PC internals.

On the outside, the only thing that really gives away this particular Xbox’s new lease on life (when the purple LEDs are off, anyway) is the laser cut acrylic Steam logo on the top that serves as a grill for the internal CPU cooler. Ironically, [Pedro] did spray the Xbox white instead of just starting with a black one, but otherwise, there wasn’t much external modification necessary. Inside, of course, is a very different story.

It’s packing an AMD Ryzen 5 2400G processor with Radeon RX Vega 11GPU and 8GB of Corsair Vengeance LPX DDR4 3200MHz RAM. Power is provided by a Seasonic SS-300TFX 300W, and a Noctua NH-L9a-AM4 keeps the system cool. Even with all that gear in there, the thing is probably still quieter than the stock Xbox 360.

[Pedro] helpfully provides quite a few benchmarks for those wondering how this hacked-up Xbox fares against a more traditional gaming setup, though peak performance was obviously not the goal here. If you’ve got 45 minutes or so to spare, you should check out the video he’s put together after the break, which goes over the machine’s construction.

We’ve seen it done with the original Xbox, and now the Xbox 360. Who will be the first to send in their build that guts a current-generation Xbox and turns it into a PC for Internet fame?

[Thanks to Mike for the tip.]

DrawBot Badge Represents The CNC World In Badge Design

September 16, 2018 by 14 Comments

Badges come in all shapes and sizes, but a badge that draws on a stack of Post-It notes is definitely a new one. The design uses three of the smallest, cheapest hobby servos reasonably available and has a drawing quality that creator [Bart Dring] describes as “adorably wiggly”. It all started when he decided that the CNC and mechanical design world needed to be better represented in the grassroots demo scene that is the badge world, and a small drawing machine that could be cheaply made from readily available components seemed just the ticket.

Two arms control the position of a pen, and a third motor lifts the assembly in order to raise or lower the pen to the drawing surface. Gravity does most of the work for pen pressure, so the badge needs to be hanging on a lanyard or on a tabletop in order to work. An ESP32 using [Bart]’s own port of Grbl does the work of motion control, and a small stack of Post-It notes serves as a writing surface. Without the 3D printed parts, [Bart] says the bill of materials clocks in somewhere under $12.

We’ve seen similar designs doing things like writing out the time with a UV LED, but a compact DrawBot on a badge is definitely a new twist and the fact that it creates a physical drawing that can be peeled off the stack also sets it apart from others in the badgelife scene.
