    10 Tips for Making Great Build Videos

    A cheap tripod is better than no tripod; for years I used a $15 Sunpak with no complaints. Some fancier models cantilever over your bench, or if your bench is sturdy you can use a clamp-on articulated arm, like my Manfrotto Magic Arm and Super Clamp.Before you get started making project videos to supplement your DIY adventures, snag some solid advice from an old pro.

    Developed on Hackaday: Need Card Art — Who Likes to Draw?

    Our offline password keeper project (aka Mooltipass) is quite lucky to have very active (and very competent) contributors. [Harlequin-tech] recently finished our OLED screen low level graphics library which (among others) supports RLE decompression, variable-width fonts and multiple bit depths for fonts & bitmaps. To make things easy, he also published a nice python script to automatically generate c header files from bitmap pictures and another one to export fonts.

    [Miguel] finished the AES encryption/decryption schemes (using AES in CTR mode) and wrote an awesome readme which explains how everything works and how someone may check his code using several standardized tests. We highly encourage readers to make sure that we didn’t make any mistake, as it was one of you that suggested we migrate to CTR mode (thanks [mate]!).

    On the hardware side, we launched into production the top & bottom PCBs for Olivier’s design. We’re also currently looking for someone that has many Arduino shields to make sure that they can be connected to the Mooltipass. A few days ago we successfully put the Arduino bootloader inside our microcontroller and made the official Arduino Ethernet shield work with it.

    Finally, as you may have guessed from the picture above our dear smart card re-sellers can pretty much print anything on them (these are samples). If one of you is motivated to draw something, please contact me at mathieu[at]hackaday.com!

    On a (way) more childish note, don’t hesitate to give a skull to the mooltipass on HaD projects so it may reclaim its rightful spot as “most skulled“.

    Full-Size Power Loader Costume Is Ready For Alien Battle

    full size power loader costume

    When you’re already making a life-size statue of the Alien Queen, you may as well build a Power Loader costume to go with it. That’s Instructable user alexthemoviegeek’s attitude, and I applaud his enthusiasm. He wanted the Power Loader to be made as cheaply as possible and also wanted it to be functional. He spent about $225 on materials, and it was well worth it. Though there are many steps to the build, here’s how he made the stilts:

    Two-foot tall stilts need to be very specific. I learned that first-hand. I went to my dad’s garage where he had plenty of spare wood. I made my own design out of whatever pieces I could find. I ended up having to use an air-powered nail gun to secure the pieces of wood together. I could then build up the foam board pieces around the stilts.

    The cage was also a challenge. I’d seen other Power Loader costumes that used connected pieces of PVC pipe, but the problem with that was you could tell it was just pieces of PVC pipe, instead of a single piece of welded metal. I decided to used 1″ PVC pipes and 3/4″ connectors, both with an outer diameter of 1.25″, so that they’d have a singular diameter and look like a solid piece. I had to add some small wooden dowel pieces and hot glue to help strengthen the connections.

    Yes, it’s awesome. Just look:

    Thingiverse | Customize a 3D Printed Tree

    CustomizerTree_BlogPost
    3D print a forest of unique, customized trees using Thingiverse Customizer. With about a dozen parameters, the Customizable Tree allows you to easily generate all the flora your inner arborist desires.

    We just upgraded Customizer to a more recent version of OpenSCAD (2013.06), so we created the Customizable Tree to show off some of the new features. It now supports recursion, or the process of repeating similar shapes, in modules and functions and the scaling parameter for linear extrusions which allows the tree branches to taper.

    Additionally, the tree customizer uses a new library we wrote for handling 3D vectors and a small library for converting hue-saturation-value colors to RGB. The 3D vector library comes with some helpful functions for rotating vectors toward other vectors as well as a module for visualizing vector paths.

    Now that we’ve upgraded, we can’t wait to see what kinds of recursive designs you come up with!

    Designing a WakeUp Light

    [Akhil] and his wife recently finished their WakeUp Light project. As the name suggests, this kind of morning alarm uses light to wake you up in the morning. The main constraints when starting this relationship-strengthening adventure were cost, ability to work with any table lamp, and having a simple but effective control interface, all while keeping all the design open. The created platform (put in the wooden box shown above) is built around a Stellaris Launchpad (ARM Cortex M4 based) and uses an AC dimmer circuit found in this instructable. For our readers interested in those, [Akhil] mentions two very interesting articles about their theory of operation here and here.

    An Android application has been made to set up all the alarm parameters, which uses the phone’s Bluetooth to communicate with the (well-known) HC-05 Bluetooth transceiver connected to the Launchpad. For safety, the current design also includes an LM4876 based audio amplifier connected to the microcontroller’s PWM output. The next revision will integrate a Digital to Analog Converter and an SD-Card slot for better quality and music diversity. A presentation video is embedded after the break and you can find the official repository at GitHub.

    MakerBot Retail | Eva’s Fantastical Furniture Springs to Life

    Retail Operator Header

    Upgrading the Design Process
    Industrial Designer Eva Arnason fell in love with furniture making as a student at the Massachusetts College of Art and Design. Now that Eva is the Assistant Manager at the MakerBot Retail Store in Boston, she’s taking her love of furniture design to the next level by incorporating desktop 3D printing into her creative process.

    “I had been making furniture the old-fashioned way at a small custom furniture store that specializes in desks and shelving. When I heard MakerBot was opening a store in Boston, I wanted the opportunity to get back into the digital side of design.”

    Retail Operator Blog

    Under Pressure
    For her most recent project, Eva incorporated the natural contours of a piece of wood into a table. However, she needed to ensure her abnormally shaped table could support weight from any angle. So Eva created a 3D printed prototype on a MakerBot Replicator 2 Desktop 3D Printer. She used this miniature table prototype to test the strength of her design by putting pressure on various points across the table’s surface. Now she can design the perfect base for her creation before cutting a single piece of wood.

    “I used to spend hours making small wooden prototypes by hand,” says Eva. “Now I can use 3D printing to quickly test my designs before creating them.”

    Visit Eva and the rest of the crew at the MakerBot Retail Store on 144 Newbury St, Boston, MA. And don’t forget to explore our vast collection of ready-to-print content on MakerBot Thingiverse, the 3D design community for discovering, printing, and sharing 3D models.

    Design for 3D Printing: Prepping mechanical parts for 3D printing for Shapeways #3DThursday #3DPrinting

    Pasted Image 3 27 14 1 41 PM

    Here’s an interesting resource for how to prep files for printing mechanical parts using Shapeway’s printing service. I’m highlighting the Clearance as I found the discussion pertinent to many forms of printing, with a special consideration for SLS.

    Prepping mechanical parts for 3D printing for Shapeways:

    Designing mechanical parts for 3D printing
    What you need to know.

    Through these pictures and explanations we hope to give you a better understanding on how to design mechanical parts for 3D printing.

    • maintain a wall thickness of at least 1mm,
    • accuracy is 0.1mm,
    • always keep a clearance of 0.6mm
    • and parts may have a deviation of 0.2mm.

    When designing something mechanical that has to be 3D printed or when adding a mechanical feature to your model there are several main considerations.

    Clearance

    Clearance, the distance between a door and the door frame when the door is shut. If you make a peg with a diameter of 3mm and a hole with a diameter of 3mm, the peg will not fit into the hole. There has to be some kind of clearance at play for it to work.

    The amount of clearance would depend on the functionality of the part. The higher the clearance, the more likely it is to fit. When developing complex moving mechanical parts though, the more clearance the more inefficient the part. A good balance between clearance and efficiency is crucial for your design decisions. If you have a gear, gearbox or spring I would try to go for minimum clearance. When designing any other assembly I would go for more clearance. The minimum clearance is 0.6mm at all times. Do not go below this number or your parts will fuse.

    The reason why clearance is especially important when designing things for White, Strong & Flexible(Selective Laser Sintered parts) is because the laser melts the SLS powder and then fuses it. This coupled with the shrinkage means that if you do not get clearance right your part will fuse. So not only will it not fit exactly right it will all get stuck together and will not work at all.

    Fail of the Week: Secret Agent-Style Book Hideaway

    fotw-book-hideaway-with-laser-cutter

    Ah, the movies are an inspiration for so many projects. How many times have you seen a spy movie where a cutout in the pages of a book are hiding something? This was the inspiration which led [Paul] and his crew to try using a laser cutter to remove a handgun-shaped cutout from the pages. The fail began before the project even got started. The sacrificial book they had chosen was too thick to cut directly so they tore it in thirds for the cutting process.

    The hijinks are portrayed well in the clip after the break. The infectious giggling as this first trace of the laser cuts the outline makes the video worth watching. As they try to go deeper, the success falls off rapidly. This makes for a great Fail of the Week discussion: Why can’t you cut through multiple layers of a book with a laser cutter? Is this merely a focal length issue that would be solved with a higher-end cutter or is there something else at play here. Let us know what you think by leaving a comment below.

    Bringing 3-D Pow(d)er to the People: Profile of 3D designer evangelist Duann Scott #3DThursday #3DPrinting #shapeways

    DuannScott

    Check out this NYTimes profile of Shapeway’s designer evangelist Duann Scott, and the efforts that he has undertaken to connect Shapeways with designers and vice versa to continue to evangelize the role he envisions for 3D printing in design in the future:

    The first thing Duann Scott does when he arrives at the Shapeways factory in Long Island City, Queens, is check the bins. They are yellow and stacked in an all-white room that resembles the interior of a spaceship, and they contain the latest prints to come out of the machines, which can really stack up.

    Shapeways, a 3-D printing service and online marketplace, has been described as the Amazon of 3-D printing for its on-demand model, if not its outsize volume: The machines spit out about 120,000 objects a month, a tidal flow of design that runs from the mundane to the astonishing.

    On a recent day, a quick search through the bins revealed a pair of pliable black-frame eyeglasses, a scale model of a biplane, an intricately detailed brass ring, enough plastic train cars to form a miniature railroad and a figurine of two tiny purple women on tiny purple trapezes. To what use any of these things will be put, Mr. Scott usually has not a clue. But that doesn’t diminish the Christmas-morning grin he gets while he is fishing through them….
