Have you ever wanted to own a full-sized ShopBot? What if some geniuses somewhere made a tool the size of a coffee maker that had the same capabilities? Does an augmented reality, real-time feedback, interactive, handheld CNC router that can make objects ranging in size from a pillbox to an entire conference room table sound like a thing that even exists? It didn’t to me at first, but then I visited the Shaper Tools office in San Francisco and they blew my mind with their flagship tool, Shaper Origin.
It’s impossible for me not to sound like a fan boy. Using Shaper Origin was one of those experiences where you just don’t know what to say afterwards. This is what the future looks like.
I’ve used a lot of CNC tools in my life, from my first home-built CNC conversion, to 1980s monstrosities that ran off the floppy kind of floppy disks, and all the way over to brand new state-of-the-art vertical machining centers. I had to shake a lot of that knowledge off when they demoed the device to me.
Origin is a CNC router built into the form factor of a normal wood router. The router knows where it is on the work piece. You tell it where on the piece you would like to cut out a shape, drill a hole, or make a pocket. It tells you where to go, but as you move it keeps the cutting bit precisely on the path with its three axes of control.
At first glance, [Frank Howarth]’s turned bamboo Death Star seems like a straight woodworking project. No Arduino controlled lights, no Raspberry Pi for audio clips of an X-wing attack or escaping TIE fighter. In other words: where’s the hack?
It’s a freaking bamboo Death Star!
If that’s not enough for you, check out the pattern on the surface of the finished model. That’s not painted on – those are the layers of the laminated bamboo lumber used to create the rings [Frank] used to form the structure. After lots of turning, sanding and polishing, the characteristic vascular bundles of the bamboo create light and dark panels for a convincing effect of the Death Star’s surface detail. And although we like the natural finish, we can imagine a darker stain might have really made the details pop and made for an effect closer to the original.
Still not hackish enough? Then feast your eyes on [Frank]’s shop. It’s a cavernous space with high ceilings, tons of natural light, and seemingly every woodworking machine known to man. While the lathe and tablesaw do a lot of the work for this build, the drool-worthy CNC router sees important duty in the creation of the multiple jigs needed for the build, and for making the cutout for the superlaser, in what must have been a tense moment.
Bamboo is an incredible material, whether for fun builds like this or for more structural uses, like a bamboo bike. All this bamboo goodness puts us in the mood to call on [Gerrit Coetzee] for a new installment on his “Materials You Should Know” series.
For years, we have been graced with consumer electronics that run some form of Linux, have a serial port on the circuit board somewhere, and are able to be upgraded through official and unofficial means. That digital picture frame you got for Christmas in 2007 and forgot to regift in 2008? That’s a computer, and it would make a wonderful Twitter feed display. Your old Linksys WRT54G router? You can make a robotic lawnmower out of that thing. The ability to modify the firmware of consumer electronics is the cornerstone of Hackaday’s editorial prerogative. Now that right we have all enjoyed is in jeopardy, thanks to regulations from the FCC and laziness from router manufacturers. Continue reading “FCC Locks Down Router Firmware”→
Like ridiculously large electromechanical devices? [Fran] took a tour of the Wanamaker Pipe Organ in Philly, the largest fully playable pipe organ in the world. The scale is tremendous – 28,000 pipes in 463 ranks spread out over five floors of a department store.
The Nintendo Entertainment System is well over thirty years old now, and still there are only about ten or so games that require the Nintendo Zapper, the light gun so primitive you can use a light bulb to beat Duck Hunt. Now there’s a new game: Super Russian Roulette. Yes, it’s Russian Roulette with the NES Zapper. It’s actually a very advanced game for the NES, using a lot of Pulse Code Modulation (PCM) for real audio in the game. Of course it’s also Russian Roulette with a gun that doesn’t look like a revolver, making this the perfect game to introduce young children to the wonders of the Nintendo Entertainment System. Video demo.
Tektronix has a new logo! It’s not as cool as the old CRT flying spaceman globe thingy logo, but at least it’s not awash with 90s era corporate industrial design motifs.
The new logo is finally a logo and not just a serif typeface with a red slash below it. In keeping with every new corporate branding in recent memory, the new typeface is a sans-serif with a few bits cut off here and there. Is it a good logo? I’m sure it tested well in focus groups. Sometimes art is more of a science than an art. A lot of people don’t get that.
Setting up a desktop CNC brings along two additional problems that need to be resolved – noise and dust. [Nick] upgraded from a Shapeoko2 to the Shapeoko3 and decided to build a fresh dust and noise proof enclosure for his CNC , and it turned out way better than he had anticipated.
When trying to build something like this, aluminium extrusions seem like the obvious choice for the structure. Instead, he opted for low-cost steel frame shelving units. The 3mm thick steel frame results in a nice rigid structure. The top and bottom were lined with 18mm thick MDF panels. For the two sides and back, he choose 60mm noise dampening polyurethane foam lined with 6mm MDF on both sides, and held together with spray adhesive and tight friction fit in the frame.
The frame was a tad shallower and caused the spindle of the Shapeoko3 to stick out the front. To take care of this, he installed an additional aluminium frame to increase the depth of the enclosure. This also gave him a nice front surface on which to mount the 10mm thick polycarbonate doors. The doors have magnetic latches to hold them close, and an intentional gap at the top allows air to enter inside the enclosure. A 3D printed outlet port was fixed to the side wall, where he can attach the vacuum hose for dust collection. The final step was to add a pair of industrial door handles and a bank of blue LED strip lights inside the enclosure for illumination.
It’s a simple build, but well executed and something that is essential to keep the shop clean and dampen noise.
Cheap consumer WiFi devices are great for at least three reasons. First, they almost all run an embedded Linux distribution. Second, they’re cheap. If you’re going to break a couple devices in the process of breaking into the things, it’s nice to be able to do so without financial fears. And third, they’re often produced on such low margins that security is an expense that the manufacturers just can’t stomach — meaning they’re often trivially easy to get into.
The hack begins with [Benajmin] finding a telnet prompt on port 11880 and simply logging in as root, with the same password that’s used across all Zsun devices: zsun1188. It’s like they want to you get in. (If you speak Chinese, you’ll recognize the numbers as being a sound-alike for “want to get rich”. So we’ve got the company name and a cliché pun. This is basically the Chinese equivalent of “password1234”.) Along the way, [Benjamin] also notes that the device executes arbitrary code typed into its web interface. Configure it to use the ESSID “reboot”, for instance, and the device reboots. Oh my!
From here [q3k] and co. took over and ported OpenWRT to the device and documented where its serial port and GPIOs are broken out on the physical board. But that’s not all. They’ve also documented how and where to attach a wired Ethernet adapter, should you want to put this thing on a non-wireless network, or use it as a bridge, or whatever. In short, it’s a tiny WiFi router and Linux box in a package that’s about the size of a (Euro coin | US quarter) and costs less than a good dinner out. Just add USB power and you’re good to go.
The hack itself is simple. [daffy] locates unused USB data lines, adds in a 5V voltage regulator to supply USB bus power, and then connects it all to a USB sound card. Hardware side, done! And while he doesn’t cover the software side of things in this first video, we know where he’s headed.
The WRT54G router was the first commodity Linux-based router to be extensively hacked, and have open-source firmware written for it. If you’re using OpenWRT or dd-wrt on any of your devices, you owe a debt to the early rootability of the WRT54G. Anyway, it’s a good bet that [daffy] is going to find software support for his USB sound card, but we remain in suspense to see just exactly how the details pan out.
Our favorite WRT54G hack is still an oldie: turning a WRT54G into the brains for a robot. But that was eight years ago now, so surely there’s something newer and shinier. What’s the coolest device that you’ve seen a WRT router hacked into?
