      A bit strange the use of an output resistor instead of the usual inductor. Could it be a power resistor with enameled wire wound around it (incorrectly marked as a resistor) to make an inductance with very low Q thanks to the low resistance?

      • Yep, someone clued me up that the inductor is indeed wound around the resistor. It’s a mistake not being on the schematic.

      Hi Dave
      Ive been using the Matrix hardware & flowcode for several years. Its very high quality and the support via the web forums is first class.
      The D connector is used because it is hard wearing and can stand the educational market.

      Flowcode lets you develop complex systems without touching C or assembler, but you can still use snippets of them in the flowchart to fine tune

      Hope to see you on the forums soon, you’ll certianly be made very welcome , we are a very friendly community.

      Hi Dave, I dabble with the Flowcode and EBlocks using them to rapid prototype various ideas. The real power of the system for me is the Flowcode software, my entire PIC program is made of building blocks of code and if I wish to add CAN or a Wireless LAN to my E-blocks project, the Flowcode software allows me to simply drop in a ‘component’ or block of code; after a few user settings, its pretty much working.
      As a non coder, its a stunningly quick method of prototyping embedded projects, I don’t need to get into the nitty gritty for every part. However the system is also very well supported and open, if I want to tweak the software component or add something completely custom I can do so. I did fear it would be a quite a limited educational toy but now understand it to be anything but. It may not be the cheapest way to start a hobby but a bargain for industrial dev and the speed of development (especially for non-programmers) is very rapid. Using low cost connectors like the D9 works for me since I make up a lot of my own custom e-blocks to tryout various chips and modules not supported in the e-block hardware. Sure I’m a Fanboy but I think you’ll find a lot more depth and longevity to this system than at first appears.
      Keep up the good work Dave.

      • Good to hear feedback someone who’s actually used it, thanks.
        I don’t see it being an affordable option for any hobbyist really, it’s target market is clearly the formal educational market.

          Hi Dave
          Ive been collecting the kit for the last 5 years or so started with a few basic boards and added the more advanced ones over time.

          There are a lot of “hobbyist users out there all over the world”

          For me whats makes them stand out apart from product quality is the level of support both hardware & software we get from MM (and its free support)

      Stay well clear of flodins.info

      I Visited the flodins.info website on 27 aug 2012 and found nothing on the 100W amp kit, in fact other than the menu there was nothing on the site.

      On the 28th I got an email from google saying I needed to reset my gmail password as they had locked my account after someone from Poland tried to hack my gmail account, flodins.info is a Polish website and the hack happened minutes after my visit, is this a coincidence?

        Don’t think he owns the site anymore, it is domain parked now.
