    Iterative Design Strategies Behind “Brick Wall” Animation by Tigran Kostandyan #3DThursday



    Iterative Design Strategies Behind “Brick Wall” Animation by Tigran Kostandyan. From 3D-dreaming.com:

    The process of iterative design became the main element in the development of this project, the brick wall. During the sequence of design, I came to a point of realization that evaluating more than 500 iterations was essentially impossible. However, the use of animation made it possible for me to find the best 16 walls, which are presented here.

    The objective for the process was to discover happy accidents, or in other words, manifestations of repetitive endeavor. The end goal became a search for a frame in animation that was aesthetically pleasing.

    Awww Shoot! My Spool Doesn’t Fit My Holder

    spoolholder-main

    The great thing about standards is that there are so many to choose from. Filament spools certainly do not deviate far from this sarcastic saying. So what are we 3D Printer folks to do? Here are a couple completely different DIY options:

    [Mark] made a spool holder that can accept 2 different width spools. This design uses skate bearings to support the spool on two points at each end. There are 3 sets of bearing blocks to accommodate the 2 different width spools. When either size spool is installed, one of the bearing block sets goes unused.

     

    [Ben] took a different approach to the same problem. His design holds the spool on its side making the spool width have no affect on the holders’ functionality. The parts for this spool holder are recycled from an old computer CD drive. If we’d have to suggest anything, it would be to add a little resistance to the spinning turntable to prevent uncontrolled filament unraveling (we’ve all been there).

    Architect Brian Peter’s “Building Bytes” 3D printed bricks #3DxArchitecture #3DThursday #3DPrinting


    Building Bytes by Brian Peters on Vimeo

    Architect Brian Peter’s “Building Bytes” 3D printed bricks. From Dezeen:

    Architect Brian Peters has adapted a desktop 3D printer to produce ceramic bricks. “I’ve been working with desktop 3D printers for the past couple of years and wanted to transform the machine to build something on a larger, more architectural scale,” Peters told Dezeen.

    A 6-week residency at the European Ceramic Work Centre in the south of the Netherlands provided him with the opportunity to experiment with printing ceramics from a liquid earthenware recipe normally used in mould-making. The only modification required for the printer was the addition of a custom extrusion head.

    The resulting Building Bytes project predicts that 3D printers will become portable, inexpensive brick factories for large-scale construction. “You could have several of these machines working simultaneously on site using pre-made or locally manufactured material,” he says. “It doesn’t have to be necessarily ceramic – it could be concrete or cement any mixture of building materials.” …

    AVC 2014 Course Preview

    Have you ever wanted to spend six months toiling over a workbench creating a robotic masterpiece only to see it explode in a ball of flames five seconds after you turn it on the day of the race? We’ve got the perfect competition for you: the SparkFun AVC! The Autonomous Vehicle Competition lets you put your autonomous vehicle through the paces with a separate ground and aerial course. The competition happens June 21st at the Boulder Reservoir. Check out the AVC site to learn more. We returned to the battlefield this week to shoot a short video detailing the course changes for this year.

    As we’ve mentioned in previous AVC posts, the course will remain pretty much the same as it did last year, with a few minor tweaks. For ground, we’re adding a line (for line followers) to make it easier to enter the Micro/PBR class, which has size and cost restrictions. For the aerial entrants, we’re adding three red balloons of death that can be either obstacles or an opportunity for more points. For the full rundown of the rules, click here. Also, it might be a good idea to re-watch the course preview video from last year.

    alt text

    We’ve also added a bit more information regarding the obstacles you’ll encounter. We now have the paint colors for all the obstacles, as well as a link so you can purchase your very own balloons for practicing. Be sure to check out all the information provided, including GPS waypoints.

    You have until May 21st to register, so head on over to the AVC site to register, read up on the rules, or check out videos or pictures from previous competitions. For anyone already registered, you have until May 21st to send us a “proof of concept.” At the end of this month, we will send out a reminder with more details. Also, the AVC is free to come and watch. So bring the friends - we’re covering the entrance fee for the reservoir for that day. See you then!

    3D Printing and Chocolate Molds: Tempering and Pouring #3DxKitchen #3DThursday #3DPriting


    SoftSolderTempering

    Ed Nisley has been sharing a series of posts based on his experiments with 3D printing for mold making.
    Chocolate Molds: Tempering and Pouring.

    oft Solder, blog. Here are some observations about chocolate tempering
    :

    Having experimentally determined that tempering molten chocolate is not optional (i.e., chocolate doesn’t behave just like butter), I tried a cheat discussed in the comments following that helpful post. Basically, because all retail chocolate is already tempered, you can get good results by carefully heating it to the proper temperature, then pouring it into the molds… the proper crystals remain in their places, the cooled chocolate has good snap, and you avoid a huge amount of fuffing and fawing….

    Hackaday Retro Edition: Parallel Port Ethernet

    It’s time once again for a roundup of ancient hardware that has successfully loaded our retro edition. Up this time is a completely random and totally not planned roundup of parallel port to Ethernet adapters.


    First up is [Tom Moss] with his IBM 5150 – the first ‘IBM Compatible’ home computer, progenitor of the i7 boxxen warming your ankles as you read this. This machine comes standard with a 4.77 MHz 8088 CPU, 8087 FPU, 512k RAM, two 360k 5.25″ floppy drives, and a few very cool additions: an ISA to CompactFlash card adapter, giving [Tom]‘s box 4GB of storage.

    How is [Tom] connecting to the Internet? A Xircom PE3-10BT Network Adapter. This neat device turns any parallel port into an Ethernet. With a Telnet program, [Tom] was able to connect to a Unix system and use Lynx to browse over to the retro site. He’s yet to get a DOS browser working, but FTP is go, allowing him to download ancient software directly onto his huge CF card.

    The next one isn’t exactly vintage, but it does carry the spirit of antiquated hardware onto the web. [Valentin] is using a FleaFPGA and a 186 over at OpenCores. The FPGA board gives him VGA output, an SD card, A PS/2 keyboard, but no options for networking. That’s no problem for [Valentin], as he wired up a Xircom PE3 parallel port to Ethernet adapter. Yes, the same adapter as the 5150 above. [Valentin] says his parallel port hack is a bit of a mess with non-bidirectional and no dedicated IRQ hardware support. It works, though, so we can’t fault him for that.

    We’re always looking for people who have loaded our retro edition on old hardware. If you have some outdated hardware sitting in the attic, get it out, load up Hackaday Retro, and send it in.

    Pics from [Tom] and [Valentin] below.

    Cosmo Wenman’s Life-size 3D Printed Portrait Mashup #3DxArt #3DThursday #3DPrinting



    Cosmo Wenman’s Life-size 3D Printed Portrait Mashup:

    My client asked for a life-sized 3D printed portrait of a colleague. Because the portrait was to be a surprise gift, there was no opportunity to scan the subject. The piece had to be modeled from photos of him culled from the web.

    I proposed a bust, roughly from the shoulders up, with classical allusions, but I was vague about the details beyond that. The final design references the Artemision Bronze, Leighton’s An Athlete Wrestling with a Python and a few other sources.

    …This is the result….” å

    Shared on the Adafruit Forums:

    I want to share my customer feedback. I believe a company that sells its own products is only as good as its customer service/support. It’s the product/customer support after the sale that keeps the customers satisfied and helps grow your future sales. I want to tell Adafruit that I am 100% satisfied with their product design/production, quality control, sales, shipping, and service/support. Adafruit has exceeded my expectations! I have never had any problem with any part of your company. I also want to give recognition Rick in the Adafruit Service Forms for his help in my posts. Thank you Rick. Thank you again Adafruit. =) I will be an Adafruit customer for life! Thank you Adafruit and Rick.

    Kyub MIDI Keyboard Puts a Piano in Your Pocket

    [Keith Baxter] loves making electronic instruments. His latest vision has come to life as Kyub, an open-source MIDI keyboard. [Keith] has previously graced our site and cracked Popular Science with his servoelectric guitar.

    [Keith] wanted to make a completely open source instrument that’s elegant, useful, and a bit more accessible than the servoelectric guitar, so he teamed up with a hacker/electronic music expert and an industrial designer. He built the early prototypes around an Arduino Uno. The current iteration uses a Teensy 2.0 and is available in various forms through Kickstarter. [Keith] opened the Kyub up to crowd funding in an effort to obtain volume pricing on some of the parts as well as an Eagle license to make the PCB files available commercially.

    The Kyub has eleven pressure-sensitive capacitive keypads on five sides of the cube. The accelerometer can be used to vary note volume, bend the pitch, or whatever else you program it to do. Of course, you’ll need a computer with a synthesizer program, but [Keith] says it is compatible with most software synth programs, some of which are free.

    There’s a demo video of an early prototype after the break. Videos of the Kyub in its current form are available on the Kickstarter page.

    Wearable flames with fur and LED strips

    wearable-flames-with-fur-and-LED-strips

    [Finchronicity] over on Hackaday Projects has made a pretty awesome furry LED Vest to keep him warm and well lit at this year’s Burning Man. He is using a Teensy 3.0 that drives strips of 470 WS2811 LEDs.

    The vertically aligned strips run on a continuous sequence which reaches up to 31 frames per second using precompiled animations. The effects rendered in Processing or video mapped, are captured frame by frame and stored as raw color data to an SD card. Playback uses the NeoPixel library to control the strips. The high resolution LEDs, with the video mapped fire and the long pile fur, create one of the nicest flame effects we have seen on clothing.

    We’ve also seen the Teensy 3.0 and WS2811 LEDs used as a popular combination for building huge displays, a 23ft tall pyramid, and more recently in the RFID jacket at Make Fashion 2014. Have you made or seen a great Teensy/WS2811 project you would like to share with us? If so, let us know the details in the comments below.

    How to make your own Primo prototype using digital fabrication and Arduino boards

    primo doc

    Primo‘s team sent us exciting news from their HQ about their contribution to the open source community. After the successful Kickstarter campaign to launch the wooden play-set that uses shapes, colours and spacial awareness to teach programming logic through a tactile, warm and magical learning experience, they took a step further. They released all the documentation and the instructions to produce a Primo prototype,  different from the product that they make and sell.

    We just finished the first edition of the Primo play-set open documentation, that includes the design files that we used to make our first prototype and a step-by-step guide to make your own version of the Primo play set. This “maker” version of our product can be assembled using rapid prototyping techniques and common tools like Arduino boards.

    We recently published a preview of this documentation just for our Kickstarter backers, who already started to build their projects and to translate the document in their language. The FabLab in São Paulo for example already translated it in Brasilian Portuguese, while other languages like Dutch, Italian and Japanese are now in progress.

    The whole documentation is completely transparent: it’s written in Markdown using Jekyll and GitHub pages. In this way it is very easy for creators to modify, translate and use it as a starting point for their projects.

    In parallel we are developing an industrial version of our product, using manufacture-quality materials and custom Arduino-compatible electronic boards.

     

    Primo

    And if you want to read about the experience of a dad making a DIY version in 1 month and a half of work, follow this link.

    Primo is an Arduino At Heart partner. If you have a great project based on Arduino and want to join the program, read the details and then get in touch with us.

    How To Make Your Cosplay Props Look Like Metal


    prop metal texturing_header

    Making plastic or craft foam look like metal isn’t the easiest trick in the world, but it can be done. This is a great skill to learn to help you with cosplay props and weapons and also armor. DeviantArt user Risachantag came up with it. First, the plastic shuriken were coated with a base coat of chrome spray paint. To make it look more like worn and used metal, she used a dry brush first. After you dip your brush in black paint, do the following:

    “Scrub the brush on newspaper for a bit until there’s only a little bit of paint on the brush. Putting pressure on the brush until it splays out, scratch the brush around so that the paint comes off the brush unevenly to give a rough texture.”

    See the full tutorial at DeviantArt.

    Re:load Pro, an Open Source Active Load

    reload-pro

    Open source test equipment has to be one of the best gifts open source hardware has given back to the community. Nowhere is this more true than in the case of  [Nick's] Re:Load Pro over on Kickstarter. Unlike resistors or similar dummy loads, an active load will always draw the set amount of current regardless of voltage. Active loads are often used to test power supplies and batteries. Is that 2500 mAh LiPo battery overstating it’s capacity? Can the power supply you just designed handle 2.5A at 12V? Both of these are jobs where active loads would come in handy.

    The Re:Load Pro is actually the third version of the Re:Load. [Nick] designed the original Re:Load after becoming frustrated at the lack of a cheap active load for testing a power supply. Plenty of people showed interest in the Re:Load, but they wanted more features. That’s where the Re:Load Pro comes in. More than a straight analog design, the Pro has a Cypress PSOC 4 Arm Cortex M0 processor running the system.

    [Nick] and his company, Arachnid Labs, are no strangers to us here at Hackaday. When we last covered [Nick], he was asking the USB Implementers Forum about a low cost Vendor ID option for open source hardware projects. Fittingly, the Re:Load Pro is an open source project. The schematics and source code are available on Github.
