    Yesterday,  I attended the EuroGamer Expo (EGX), 2014, at the Earls Court Exhibition Center in London, U.K. The journey up to London, by train, did not start too well, due to works being carried out on the railway tracks. This meant that we first had to go to Brighton to catch another train up to London. Hence, a journey that should have taken an hour and a half ended up taking about three hours. When we got to London Victoria Station the Circle and District underground lines were closed, which meant taking the C1 bus to Earls Court and us arriving almost an hour and a half late.

    Posted by on in Robotics Using FPGAs

    Hello and welcome to another post in the blog series on using FPGAs in Robotics. So far the series has concentrated on the construction of a 17 DOF robotic kit, which was purchased without any assembly instructions. This kit, when fully constructed, will be central to this series of blog posts and should be controlled using one of Altera's Cyclone family of FPGAs on  a development board or kit. In this blog post I will finish the construction of the lower limbs and add the waist bracket, which will eventually act as our Inertial Frame when the Denavit-Hartenberg parametric representation of articulated joints is considered.

    Hello,

     Quite recently I set myself a task to print in 3D one object, out of many, from a 3D scene in AutoCAD. How this is, or should be done, left me perplexed for a while. However, I soon realised that this objective is not too difficult a thing to do, like most objectives, once you know what you are doing, or are supposed to be doing!  Especially, where in my case, probably like with most 3D printers, the printer's  application software accepts 3D models in the .stl or Lithography format. By the way, in case you don't already know, my 3D printer is an UP! Mini 3D Printer.

    With this objective in mind, in this blog post I demonstrate how I 3D print AutoCAD models using any 3D printer in general and the UP! Mini 3D printer in particular. Hence, the method should work for any 3D printer software that supports the .stl file format.

    Hello, welcome to my blog posts about 3D printing. Last week I received my UP! Mini 3D Printer and began the installation process. However, I started relatively late on Sunday and didn't have time to complete the task during the week. Having a weeks' break wasn't so bad, as it allowed me to reflect on what has been achieved so far, which in all honesty is not very much.

    In this post I describe the trails and tribulations I have been through to print my first 3D model.

    Posted by on in First Impressions

    This blog post is about my first impressions of the GY-80, a 10 Degree-Of-Freedom (DOF), 9-Axis Accelerometer, Magnetometer, Gyroscope and Barometer Module, which I purchased and have just received two of.  This module is typically used in quadcopters, robotics and similar products where balance and stability are of interest. Indeed, I bought the GY-80 for my 17 DOF Robot that some of you have been reading about in my  FPGAs and Robotics blog category.

    3D printing is yet another new blog category being introduced on the website. Wow! I must be planning on working hard. I decided to launch this category with the arrival of my new UP! Mini 3D printer. The purpose of this category is, as its name suggests, provide an outlet for me to blog about my experiences in 3D printing.

    There are three main reason why I bought an UP! Mini 3D Printer. Firstly and chiefly I bought it because of the reduced price, which is probably due to a new version being released soon. Secondly, I bought the UP! Mini because of its cute size. I really didn't want one of those DIY printers that belong more in a workshop than in a living/work room.

    I quite found these pictures by chance, while transferring some photographs from an iPad 4 to  a Voyager Air 2 network drive. The photographs were taken with an iPad 4 at the Musee Memorial d'Omaha Beach on the Avenue de la LibĂ©ration, St Laurent Sur Mer, Normandie, France, while on holiday last year. Anybody, who is anybody and has seen the opening sequence of Saving Private Ryan, which is regarded as having the most realistic opening sequences to any film , ever, must visit one of the many museums in this area of France.

    Although aimed at tourists a lot of the memorabilia found in  the museums bring home the reality of war and given the current standoff between NATO and Russia why we cannot afford another one. In total about 3881 American soldiers were killed, wounded or reported missing on 6th June 1944 at Omaha beach alone. I took a lot of photographs of the radios of the time, as we will eventually be hosting a series on Software Defined Radio (SDR) on this website.

    In the last installment,  in this category of posts, I produced a 3D CAD drawing of a covering for the screws that protrude out from the footbase. In the blog post before that I introduced the parts of the kit and discussed the assembly of the lower part of the legs. In this installment I will discuss the parts that I have used to assemble the upper parts of the legs.

    Firstly, to confirm the CAD drawing produced previously was proceeding along the right track I printed out the CAD drawing and placed the lower assembly build next to it, as can be seen in the image on the left. The result is quite pleasing to see, as it confirms that the dimensions of the CAD model that will eventually be printed on a 3D printer are as expected. This has given me enough confidence know that the 3D model design is progressing along the right path.
