    How To Make a Cute, Pint-Sized Captain America Costume

    captain america

    When Instructables user mrcrumley noticed his four-year-old son was pretending his frisbee was Captain America’s shield, he realized he needed to make him a Captain America costume for Halloween. Steve Rogers has never looked so adorable. Mrcrumley was able to hunt down many of the materials at a thrift store, and he was resourceful. He found a pair of duffle bags and stripped them to provide the buttons, snaps, straps, etc. that he needed for the costume. He made the mask from papier mache using this process:

    To make a mask pattern that would fit well, I wrapped my son’s head in plastic wrap and applied little pieces of tape (paper-mache-style) to the plastic. Then, I slipped it off his head and cut it out into pieces that would lay flat. These pieces became the patterns for the mask. Then, I sewed together the pieces into a rather fashionable mask (if I do say so myself).

    Pressing the mask’s seams was a bear (particularly the eye-holes). And in the end, I had to resort to hot-gluing the seams to the underside of the mask. This was the only way I could keep them from poking into my son’s eyes.

    Hackaday 68k: So You Want A Kit?

    68000

    It’s yet another update to the Hackaday 68k, the wire-wrapped backplane computer that will eventually be serving up our retro site.

    This is also a demo of Hackaday Projects, our new, fancy online documentation tool for all your adventures in making and tinkering. Did you know we’re having a contest on Hackaday Projects? Make something sci-fi, and you’re in the running for some really good prizes. There’s soldering stations, o-scopes, and a lot of other prizes being thrown at the winners. It’s awesome. First one to build a working Mr. Fusion wins.

    In this update, I’m going to go over the beginnings of the video board, why Hammond enclosures are awesome and terrible at the same time, and some thoughts on turning this into a kit or product of some type. Click that, ‘Read more…’ link.

     

    The Video Board

    Like I’ve said before, I’m using the Yamaha V9938 video display processor as the graphics chip on this computer. It’s the easiest way I can get an 80×24 text mode – perfect for that *NIX goodness – and should be able to pull off some cool demoscene stuff. It’s pin compatible with the V9958, so I have that option, and it’s also fairly simple to interface to the rest of the computer:

    V9938

    That’s from the V9938 Technical Data Book. Big PDF warning there. On the right side of that graphic is the DRAM interface for the video memory and the pins for video output. There are a few different configurations ranging from 16k of VRAM to 128k of VRAM. Of course I’m going with the 128k option, using a quartet of TMS4464 DRAM chips I picked up from Jameco. Here’s the schematic of the VRAM interface:

    Dram

    V99X8I don’t want to wire wrap that. It’s a lot of fiddly, short bits of wire. It’s also extremely simple and won’t be seeing any changes in its design.  The solution to my laziness is, of course, to make a PCB.

    Because the connections to the V9938 are just an 8-bit data bus and a few control signals, and the output is dead simple for composite output, this greatly minimizes the amount of wirewrapping I’ll need to do. Even if I tried wrapping a V9938, I’d run into a problem: the pin pitch isn’t 0.1″, rendering all my wirewrap adapters useless.

    If you’re wondering about the physical size of the board, it’s just a wee bit larger than an Arduino. Yes, I know what you’re thinking, but a 128kB V99X8 will not fit on a standard Arduino shield. 16kB, maybe. In any event, when I get these boards back, I’ll have a go at driving it with an Arduino. Just because.


    Mechanical Considerations

    Yeah! Fancy Video!

    Import DXFI’ve never had any luck with Hammond enclosures. The die-cast aluminum guitar pedals? I’ve ruined dozens of them drilling holes for pots, switches, and jacks. The enclosure for the 68k is no different. It’s a beautiful case, no doubt about that, but I am cursed with a mystical ability to always mess up the drilling, painting, or some random thing when it comes to Hammond enclosures.

    The original plan for this backplane + enclosure combo was to have a small extension board on the front (hence, “frontplane”) that broke out the power and reset lines so this computer would at least look the part of an early 80s homebrew computer. Also, having a power and reset switch on the outside of the case is a good idea anyway.

    PhysicalBecause of the complete failure of my ‘frontplane’ plan with the stock front panel, I’m going for something much, much cooler: a custom CNC’d aluminum panel. Right now I have holes for a power switch, a reset button, and a 5mm LED for power indication.

    The basic circuit for this frontplane is very simple: The lines on the backplane are broken out on a huge 2×32 pin header. There’s also a small three-pin header for the PS_ON and POWER_OK lines for the ATX power supply. Ground the PS_ON line with the switch, and the power… uh, turns on. The PS_ON line provides +5V when the power is on. Attach the LED to that.

    The reset circuit is the same from the CPU board: a Maxim DS1812 supervisory and reset circuit in a single TO-92 package.

    wireframe

    Creating the milled front panel and new, improved frontplane was an interesting exercise in mechanical design. First, I created the front panel as a 3D model, exported the top view as a DXF, and imported that into Eagle. Then, I took the board file for the backplane and overlaid the holes. Then it’s just a simple matter of removing the parts and traces from the backplane I don’t need – everything except the pin headers – and making a board.

    Betterfrontplane

    Apparently the Dimension layer in Eagle has a keepout. This board is far too simple for me to care about doing it properly.

    So there you go. Fun adventures in mixing mechanical design with circuit board creation. This, like just about everything else relating to the 68k project, is up on the github.

    Oh yeah, a kit

    For some reason I can’t comprehend, a lot of people have asked if I’m going to make the 68k into a product, or at the very least a kit. I don’t quite understand the demand; the fun of homebrew computers is designing and building them.

    That doesn’t mean I won’t entertain the idea. In its current form, though, a 68k kit would be absurdly expensive, take hours and hours to assemble – the RAM card alone would be three or four hours – and would have an extremely high number of unsatisfied buyers. It only takes one misplaced wire to screw the entire thing up, you know.

    So, an improved,  single-PCB kit is the only option. This is months and months in the future, but here’s what I’m thinking:

    • Uses the currently-in-production 68SEC000
    • Already assembled.
    • A MiniITX or MicroATX motherboard form factor.
    • Uses 30 or 72-pin SIMMs for the RAM.
    • Some sort of expansion port.
    • User-updatable ROM.

    That last bullet is the sticking point. I’ve been turning this around in my head for a while, and I can’t come up with a good way of doing it. The problem is I need a small amount (~64kB) of EEPROM or Flash that can be accessed on a parallel bus. That means 15 address lines, 16 data lines, and control signals. I need a way of reprogramming this, in system, with few additional parts, cheaply.

    The obvious solution is to throw a big FPGA in the system for address decoding, an SPI bus, and in-system reprogramming of the ROM. That may end up being the eventual solution to this problem, but I’m thinking there’s an even more clever and cheaper way of doing things.

    I’ve toyed around with doing the whole ‘in system ROM reprogramming’ thing in a 6502-based retrocomputer, and it is possible by using a microcontroller and a bunch of shift registers to program the ROM. This takes up a lot of board space and is extremely kludgy.

    Another solution would be something like this amazing retrocomputer that actually should be a product. It uses a 40-pin PIC microcontroller as the RAM, ROM, and ACIA. It is, without question, the most innovative project in the retrocomputing world for the past few years and presents an interesting solution to the problem of in-system ROM programming: just put the ROM on a big microcontroller.

    Are any of these ideas the right solution? I don’t know, because I’m not designing this computer as a product right now. This problem has been bothering me for a while, and I’d love to hear some more ideas. In any event, there’s plenty of space on my ROM board to prototype some in-system reprogramming. Come up with a good idea and I might put it in.


    That’s it for now. You can continue to follow the progress of the Hackaday 68k over on Hackaday Projects. Be sure to comment and give a skull to the project. Seriously, give the project a skull. I’m losing to [Mathieu]‘s Mooltipass project in the skull department. I need more skulls.

    Soft Robot Glaucus Moves Without Spine, Armature, or Hardware #3DThursday #3DPrinting

    From the description for Super-Releaser Robotics‘s recent soft robot Glaucus:

    We’ve been developing methods for creating durable, inexpensive soft body robots. Fundamentally, the technology involves designing a robot in CAD, 3d printing molds for the interior and exterior of the bot, and casting it in silicone. 

    These methods offer a few advantages over traditional subtractive fabrication. First, iteration is fast and dynamic. It is simple to design a parametric bot in CAD and simultaneously print multiple experiments and prototypes to flesh out and understand new forms.

    Second, casting is inexpensive and incredibly repeatable. Once a successful design is fleshed out, creating an army of exact duplicates of this winning robot is as simple as casting the mold multiple times. The mold can even be duplicated for mass casting. This means stress testing never risks destroying one precious irreplaceable prototype.

    Third, the designs that are developed using these methods easily translate into a manufacturing context. Printing and machining high volume production molds based on the initial CAD follows the same tool chain as any other industrial casting process. If a project calls for thousands of identical silicone robots, HTV (high temperature vulcanizing) silicones can be injected into machined molds just like any mass produced plastic part….

    Doctors Use 3D Printing To Help A Baby Breathe #3DxMedicine #3DThursday #3DPrinting

    Nicole Haley

    Doctors Use 3D Printing To Help A Baby Breathe:

    Ever since the day Garrett Peterson was born, his parents have had to watch him suddenly just stop breathing.

    “He could go from being totally fine to turning blue sometimes — not even kidding — in 30 seconds,” says Garrett’s mother, Natalie Peterson, 25, of Layton, Utah. “It was so fast. It was really scary.”

    Garrett was born with a defective windpipe. His condition, known as tracheomalacia, left his trachea so weak the littlest thing makes it collapse, cutting off his ability to breathe.

    …So the Petersons contacted Dr. Glenn Green at the University of Michigan, who specializes in conditions like Garrett’s. He teamed up with Scott Hollister, a biomedical engineer who runs the university’s 3-D Printing Lab, to create a remarkable solution to Garrett’s problem — a device that will hold open Garrett’s windpipe until it’s strong enough to work on its own.

    …3-D printers have been used to build jewelry, art and even guns. But Hollister is using the technology to create medical devices. He uses a 3-D printer that melts particles of plastic dust with a laser. He has already built a jawbone for a patient in Italy and has helped another baby with a condition similar to Garrett’s. But Garrett is a lot of sicker and his condition is a lot more complicated.

    “It’s just been issue after issue with breathing, and just trying to keep him breathing at all,” Jake Peterson, Garrett’s dad, says.

    At 16 months old, Garrett had never been able to leave the hospital. Every time he stopped breathing, it was a mad rush to save him. And the doctors weren’t sure how much longer they could keep him alive.

    “In some sense we were thrown directly into the fire,” Hollister says. “We characterized it as sort of a Hail Mary pass.” …

    3 DOF Open Source Robot Arm Is Just the Beginning

    Arm3-v1

    [Dan Royer] of Marginally Clever had a dream. A dream to build an open-source 6 DOF robot that anyone can make! To do so, he’s been learning robotics for the past two years, and has just finished the first step — he’s designed and built an open source 3 DOF palletizing robot!

    He’s based this little guy off of the commercial ABB 460 palletizing robot, which is a tried and true industrial robot. It features all laser cut parts, a few nuts and bolts, some stepper motors and an Arduino UNO for the brain. He’s released all of the design files on Thingiverse and the firmware on GitHub – yet another project we’d like to build if only we had a laser cutter!

    And don’t worry, the Arduino UNO is only being used for this first prototype — he’s already started writing code for the RUMBA (Reprap Universal Mega Board with Allegro-driver) controller for revision 2.

    Stick around to see it write its first greeting with a marker — Hello World!

    It’s an exciting project and we can’t wait to see further development! Keep up the good work [Dan]!

    Maybe we can teach it manually in the future too!

    3DKitbash created the Quin fashion doll originally for a crowdfunding project last year. Recently, designer Quincy has been creating and sharing a lot of exciting add-on printable content for the doll platform, including items they have been calling “UpKits” (like the hair and fist options here from Thingiverse) that they are posting all over the web where designers are posting 3D content for free or paid downloads. To my taste, the quality of these pieces are stronger than most of the paid 3D printables posted online so far, and speak to the potential strength of this marketplace.

    Here’s some tips, tricks, and techniques for using your Arduino in preparation for #ArduinoD14

    Adafruit industries blog 2

    Arduino Day 2014 is this Saturday and we’ll be posting our favorite tutorials, projects, and products for Arduino all this week. This tutorial from the Adafruit Learning System is useful to look over, especially for those just getting started working with Arduino. Get the most out of your Arduino! Here’s a little background on Arduino from our Arduino UNO FAQ page:

    There’s so many Arduino’s out there, it may get a little confusing. We wanted to clarify for people some of the changes in the latest version.

    But first…some history! First there was the serial Arduino (what’s the name of it?) with RS232 which was not used outside of the Arduino team & friends.

    The first popularly manufactured Arduino was called the NG (New Generation, like Star Trek, yknow?) The NG used the Atmega8 chip running at 16 MHz and an FT232 chip for the USB interface. The bootloader takes up 2KB of space and runs at 19200 baud.

    The next version was the Diecimila. The Diecimila updated the chip from the Atmega8 to the Atmega168. The great thing here is double the space and memory (16K instead of 8K). It still ran at 16MHz. The Diecimila also added two extra header pins for 3.3V (from the FTDI chip) and the reset pin which can be handy when a shield is covering up the Reset button. The bootloader takes up 2KB of space and runs at 19200 baud. Auto-resetting was also added which makes life awesomer for everyone.

    In 2009, the Duemilanove was released. This one also upgraded the chip again, to the Atmega328. Yet another doubling of space and memory! Another upgrade is now the power is automagically switched between USB and DC-jack which removed the previous jumper. This makes it easier and faster to move from programming to standalone and got rid of some confusion. The bootloader takes up 2KB of space and runs at 57600 baud.

    In 2010, we have the Uno! The Uno still uses the 328P chip and the power switcher. It has a smaller bootloader called OptiBoot (more space for users’ projects) that runs at 115K. So even though the chip is the same, you get another 1.5K of extra flash space that was previously used by the bootloader. The FTDI chip has also been replaced with a atmega8u2 which allows for different kinds of USB interfaces. Finally, there’s an extra 3.3V regulator (LP2985) for a better 3.3V supply. whew!

    3D Design Software – Marius Watz’s Modelbuilder Processing Libraries – Parametric Design for Digital Fabrication #3DThursday #3DPrinting

    Marius watz modelbuilder

    From the workshop description for “ITP 2013: Parametric Design for Digital Fabrication” where Marius Watz shared the latest version of his Modelbuilder Processing libraries:

    We will use a range of tools to produce output in industry standard formats (PDF, STL etc.) Our primary platform will be Processing, a Java-based coding tool that facilitates experimentation with coded processes without the constraints of conventional CAD software or design tools.

    To describe 2D and 3D structures in code we will rely heavily on principles from computational geometry. An understanding of mathematical concepts like vectors and trigonometry is essential, as these are the atomic units of geometry. These topics are introduced as part of the course, along with strategies to simplify the math involved through helpful workflows and existing code. The real challenge is not math, but rather the translation of spatial ideas into code. Sharing of code and other resources will be done through Dropbox and Github.

    To this end we will use libraries like Modelbuilder, Toxiclibs.org and Hemesh. These libraries extend the core functionality of Processing, providing higher-level abstractions that aid in the articulation and manipulation of geometry. From the basic task of constructing a valid 3D mesh to more advanced concepts like physical simulation and kinetic behavior, most challenges will be resolved through a combination of hands-on code and knowing when to use an existing tool.

    Other possible tools include Rhino/Grasshopper, Meshlab, Netfabb and Pepakura, as well as any CAD or Open Source software participants may find helpful in their chosen projects.

    Building a Network Controllable RGB LED Lamp from an Old Scanner

    EthernetLamp

    Being able to use one of your old projects to make a new one better can be quite satisfying. [Steve] from Hackshed did just this: he integrated an Arduino based webserver into a new network controllable RGB lamp.

    What makes this lamp unique is that the RGB LED bar comes from an old Epson scanner. Recycling leftover parts from old projects or derelict electronics is truly the hacker way. After determining the pinout and correct voltage to run the LEDs at, the fun began. With the LED bar working correctly, the next step was to integrate an Arduino based webserver. Using an SD card to host the website and an Ethernet Arduino shield, the LEDs become network controllable. Without missing a beat, [Steve] integrated a Javascript based color picker that supports multiple web browsers. This allows the interface to look quite professional. Be sure to watch the lamp in action after the break!

    The overall result is an amazing color changing lamp that works perfectly. All that is left to do is create a case for it, or integrate it into an existing lamp. This is a great way to use an LED strip that would have otherwise gone to waste. If you can’t find a scanner with a color wand like this one, you can always start with an RGB strip.

    Netflix Picks Up Award-Winning SXSW Documentary ‘Print the Legend’ #3DThursday #3DPrinting

    Printthelegendnetflix

    There have been a number of folks asking how they can see the startup desktop 3D printing documentary Print the Legend since it debuted at SXSW earlier this month. Here’s your answer: coming to the (small) screen near you!

    Netflix Picks Up SXSW Documentary ‘Print the Legend’, from The Hollywood Reporter:

    Netflix has acquired the rights to documentary Print the Legend after its award-winning debut at SXSW. 

    The film, which chronicles the rapid rise of 3D printing, will premiere exclusively on Netflix later this year and will be available to stream everywhere that Netflix is available. 
    Legend, directed by Luis Lopez and Clay Tweel, follows MakerBot Industries and Formlabs, two 3D printing startups as they compete with established industrial players Stratasys and 3D Systems.

    The film was produced by Steven Klein (Make Believe). The project was developed, produced and financed by Chad Troutwine (Freakonomics) and Audax Films. It took home the special jury prize for editing and storytelling in the documentary feature competition at the SXSW Film Awards earlier this month in Austin, Texas.

    “It’s so rare for a film to capture history in the making, and Luis Lopez and Clay Tweel have done just that in their skillful presentation of the elation and betrayals experienced by young entrepreneurs, detailing the groundbreaking technology of 3D printing,” said Lisa Nishimura, Netflix vp original documentary and comedy. “This is a compelling glimpse into a game changing technology as it nears an inflection point going from the fantasy world of a few obsessed visionaries to a must-have technology that may enter every home.”

    …Lopez, Tweel and Klein said in a joint statement: “To premiere in front of the most tech savvy and entrepreneurial festival crowd in the world and partner with the Netflix documentary team — who work brilliantly at the cutting edge of distribution — is truly a dream come true.”

    Electric Scooter MK 1 — Tundra Upgrade!

    P1140811_600

    After discovering his all-terrain snow scooter was terrible on ice — [Dane] decided he needed to do some upgrades.

    In case you don’t remember, we first shared [Dane's] project back in December, where he zipped around city streets covered in snow. The scooter used a big knobby tire and a front ski to slide around on. To make it suitable for ice, he had to redesign it a bit to handle slippery surfaces; he needed to give it skates.

    He had originally hoped to find figure skates at a thrift store (where he originally found the classic scooter), but had no luck — so he made his own. Some 1/2″ x 1/4″ steel bar later, a bit of welding, and he had a rather rugged front skate to work with!

    After he was content with his upgraded front-end, he started adding studs to the back tire. He’s using plain old 3/8″ self tapping screws, and a whole lot of epoxy to make sure they stay in.

    So does it work? Oh yeah.

    Piezos For Haptic Feedback

    Haptic

    The most common way to put some sort of haptic feedback in an interface hasn’t changed much since the plug-in rumble pack for the Nintendo 64 controller – just put a pager motor in there and set it spinning when the user needs to feel something. This method takes a relatively long time to spin up, and even the very cool Steam controller with voice coiled directional pads can’t ‘stick’, or stay high or low to notify the user of something.

    [Tim]‘s day job is working with very fancy piezoelectric actuators, and when an opportunity came up to visit the Haptics symposium, he jumped at the chance to turn these actuators into some sort of interface. He ended up creating two devices: a two-piezo cellphone-sized device, and a mouse with a left click button that raises and lowers in response to the color of the mousepad.

    The cellphone device contains two piezo actuators with a 10 gram weight epoxied on. A small microcontroller and piezo driver give this pseudo phone the smoothest vibrations functions you can imagine. The much more innovative color-sensing mouse has a single actuator glued to the left button, and a photosensor in the base. When the mouse rolls over a dark square on a piece of paper, the button raises. Rolling over a lighter area, the button lowers. It’s all very, very cool tech and something we’ll probably see from Apple, Microsoft, or Sony in a few years.

    Videos of both devices below.

    Glowing Oogie Boogie Costume

    oogie boogie

    Oogie Boogie is one of the scariest Disney villains as far as I’m concerned. He’s cruel and manipulative, but he does have a cool costume. Instructables user kristylynn84 fashioned the entire costume from burlap and because the costume is loose and lumpy, it meant she could take some liberties (she didn’t use a pattern). She took the extra awesome step of making Oogie glow in the dark. Here’s how she achieved that with glowing spray paint:

    We used about 6 cans. You may want to buy 7 or 8, just to be safe, and return the last one if you don’t use it. But remember, the suit will need numerous coats, and so will the mask.

    I took him outside and made him do some slow spins as I painted him up. It’s transparent, so you can’t see what you’ve done until you hold a black light to it, once it’s dried it will activate. Yes, the paint went through and I ended up painting my husband LOL, it made a cool effect. (The can says to not get it on your skin. But he lived.)

    I would say….10-12 coats of spray paint and between those, you need to go over it with a hand-held black light to see where you’ve missed any spots.
