    I am not sure each of these articles warrants an individual write up, but they can be fun and/or useful things to build.


    The Right To Build Arms

    There are few simple and complete models for robotic arms that can be controlled by simple software.  This model uses basic servos and could be adapted for lots of uses.  Servos are easy to work with and can be controlled by your system of choice, not just the one they specify in the instructions.  I think I may add some articulation to some of my bots with this design.

    You'll Get a Charge Out of This


    Here a rechargeable battery pack for your cell phone.  Even if the single cell design is not good enough for you, it is a great resource form making a rechargable backup of a larger capacity (think 12 D cells).

    Build The Robots!


    Just for fun, some customizable and posable robot figures to print.

    Since AI is a hobby for some of us, I thought I would share this article from Engadget.

    http://www.engadget.com/2015/04/09/rat-brains-are-basically-wired-up-like-miniature-internets


    What makes this most interesting is not that it looks similar to the way an internet is designed, but more importantly is how the subnets and tasks are divided.  When laying out a multi-process model (either in software or hardware) the way tasks are prioritizes and compartmentalized make a huge difference to the speed and efficiency of the system.  I expect this information will influence FPGA designers and programmers with applications from smarter Furby's to better context recognition from voice assistants on your cell phone!

    While there is not a lot of "new" coming off of this article, it strikes me because of how much ingenuity we can tap when the need is there.


    The physics/robotics/electronics teacher at this high school rigged an SLA 3D printer using Power Point slides as the software to make this REALLY small chess set.  Check out the details at http://www.3ders.org/articles/20150409-teacher-brings-diy-3d-printing-classroom-using-a-modified-projector-powerpoint-slides.html

    It seems that all the kids learn Python programming in school these days, so I guess it makes sense that some teachers used the language as their basis for the software of this 2-Camera Structured Light Scanner.  If you want a simple, open source, and  hackable version of a structured light scanner, this looks like it has your name on it!

    3Der.org passed on an interesting article last week about building a  fairly simple 3D filament extruder for around $75 in parts.  The quality may not be as consistant as a more expensive Filabot, but the design is simple enough to be made by most people and basic enough to even be come part of an injection molding system for small parts.

    Photos are up online from the April Open House.  We had a lot of fun with all of the visitors,  and the bridge building contest.  Check ot the Photo Gallery under the News and Event's Tab!

    Do you want to make your own Small windmill or solar powered Stirling Engine?


    Would You like to do it on a 3D Printer?


    Are you willing to pay a few Dollars for the plans and instructions?


    If you answered yes to these question then you too can bait your very own delusional Spaniard (Sancho Panza not included) with information from this site: http://www.reprap-windturbine.com/

    But before you do, I recommend reading about it at 3Der.org

    The $150 Windows 8.1 Compute Stick from Intel is available from several source, accord to tech web blog Engadget.  Apparently Amazon, Newegg, and others have the device available in the Windows and/or Linux versions.  (Edit, I can't find it on Amazon, anymore)


    It you were looking for the quickest, easiest way to add Windows PC to your HDMI TV this could be for you!

    The University of Houston has a working system that allows the user to control a prosthetic without the need for a direct implant.


    "The technique, demonstrated with a 56-year-old man whose right hand had been amputated, uses non-invasive brain monitoring, capturing brain activity to determine what parts of the brain

     are involved in grasping an object. With that information, researchers created a computer program, or brain-machine interface (BMI), that harnessed the subject’s intentions and allowed him to successfully grasp objects, including a water bottle and a credit card. The subject grasped the selected objects 80 percent of the time using a high-tech bionic hand fitted to the amputee’s stump."

    "The results of the study were published March 30 in Frontiers in Neuroscience, in the Neuroprosthetics section.

    Contreras-Vidal, Hugh Roy and Lillie Cranz Cullen Distinguished Professor of electrical and computer engineering at UH, was lead author of the paper, along with graduate students Harshavardhan Ashok Agashe, Andrew Young Paek and Yuhang Zhang."

    Have you ever wanted to make your own Nerf blaster?  Ryan and Kane of Mostly Harmless Arms have put plans, instructions and files on line to help you make your own darts, blasters and even a bow and arrow style blaster.  They were also at the Midwest RepRap Fair in Goshen.



    Check out their site for some interesting ideas for building and making dart blasters of your own!
