    Posted by on in Photography and Sketching

    After reading my last blog post some of the professional  photographers amongst you must have had a smug grin on your face thinking this blog category is amateur hour and will make an entertaining read. Well I definitely hope it is entertaining and although I may be an amateur toady I am resolutely determined not to be tomorrow! One day I will have a respectful grin on my face when I read a beginner's photography blog.

    Anyway, as you will see in this blog post, I'm making steady progress.

    I recently got my hands on a MicroZed Evaluation Kit from Avnet that contains a Xilinx Zynq-7010  FPGA. To use the kit one needs to install the Xilinx tools, which in this case includes the Vivado design suite.  The webPACK version of the Vivado design suite is available for download on the Xilinx website (www.xilinx.com). Navigating to the Xilinx application download page, provides download installers for Windows and LINUX platforms, but not for OS X.

    To install Vivado on a Mac or MacBook I suppose one should install the Windows version on a Windows binary emulator like WINE. Here is my experience of installing Vivado 2014.4 on LINUX, openSuse 13.1 (Bottle).

    Hello, regular readers of my En Vacances blog category know that sometimes I use a Canon EOS 550D or more recently the Canon EOS M to take blog photographs.  The Canon EOS 550D is a better camera, but I tend to use the EOS M a lot more nowadays, due to its small and compact size. Although lets face it, irrespective of which camera I use the poverty of quality in my photographs is self evident. Most of my photographs are of the snapshot variety and are generally not outstanding.

    Well this is all about to change, as I have decided to invest some time in the art of photography. I have been especially spurred on to do so, because some of my blog photographs of FPGA development boards are crap not very good, not to be too self critical. Hence, this blog post delivers the results of me knowing what the Canon EOS M's ISO setting are and how they are involved in remeding my less than flattering blog post photographs of FPGA development boards.

    I love drawing, but I've never given myself a chance to become any good at it. I love my iPad (iPad Air) too. Hence, when  I saw a device, the iSkecthNote, that happily married the two I didn't hesitate to help fund it, when it was introduced on the crowdfunding website, Kickstarter.

    However, as has been symptomatic of Kickstarter projects, this one was delivered late too, but this time I didn't mind. This was because I thought that the wait would be well worth it.

    When the engineers behind iSketchNote conceived of the idea they probably thought that it was very good one and if they turned it into a product they might be able to sell a few. They were wrong, it is an absolutely brilliant idea and it wouldn't surprise me if they end up selling them by the bucket load. This is my first impression of using the iSketchNote.

    Just after finishing this article ISKN released app version 2.1 and the Bluetooth connectivity pairing issues seem to have improved.

    UPDATE: 14/02/2015: I have now posted a follow-up review

    The Brighton Centre is situated opposite the Brighton seafront, which makes it especially nice to go to during the summer, as one can hang out along the seafront before and after a show. Although as commented previously it gets quite chilly during the winter months and a walk along the seafront is not recommended.

    It has a capacity of 4,500, which is probably its downside, as not all artists are comfortable performing in front of a maximum capacity audience of that size. 

    We are lucky every now and again though, as some major artists do come down, like earlier in the year when we had Little Mix! Next year we will be spoilt for choice with the Kaiser Chiefs and Paloma Faith performing, amongst others. We ARE spoilt for choice! Anyway, this blog entry is a continuation of the last one about Diversity at the Brighton Centre.

    Diversity are a British dance group that won a reality TV show, Britain's Got Talent,  six years ago. Ever since then they have gone on from strength to strength. We went to see them last night at the Brighton Centre, Brighton, East Sussex. It was a thoroughly enjoyable show even though it started more than an hour late, which meant that it did not end until after 11pm last night. Not good for the bambinos who had school the next day.

    I captured a small part of the show with my Canon EOS M mirrorless digital camera fitted with a Canon EF-M 18-55mm f3.5-5.6 IS STM lens. The lens was fitted with both a UV(C) multi-coat filter and a circular polarizing filter, which I forgot to take off! This blog post is my happy take of the nights event, as it unfolded.

     The Raspberry Pi camera module or more specifically the OV5647 image sensor consists of a CSI-2 image sensor interface. Quite fortunately, as the OV5647 can be found in many image sensing devices apart from the Raspberry Pi camera, like mobile phones for example, plenty of information can be garnished about this interface from the Internet. The CSI-2 is a standard interface or Camera Sensor Interface (CSI) defined by the Mobile Industry Processor Interface Alliance, usually referred to by their four letter acronym, MIPI.

    This blog post is a brain dump of the continuation of the idea of interfacing the OV5647 image interface to FPGA boards and other embedded systems like the Parallella board containing a Xilinx Zynq FPGA and the Epiphany 16-core processor. We will also like to interface this sensor to Altera FPGAs like the SocKit, consisting of the Cyclone IV FPGA and Arrows family of BeMicro evaluation kits, which contain the Cyclone V FPGA. Support should also be provided for the Beagle Bone (black) and Intel's Galileo and possibly Edison development boards.
