    Posted by on in Robotics Using FPGAs

    Hello and welcome to another one of my scientific computing journeys. This time it is into the world of Robotics and Field Programmable Gate Arrays (FPGAs). I've been toying with the idea of building a FPGA controlled robot for quite some time now, but I have not really been motivated by the four wheel chassis ones available on the market. By chance on Tuesday I came across a 17 Degrees of Freedom (DOF) Biped Robot Educational Kit, from Ali Express, for peanuts.

    Now normally I would be suspicious of a potentially good kit for the price being offered, however given the recent news about Ali Express' 100 Billion Euro stock market floatation I convinced myself that they must be doing something right, so I took the plunge and bought one.

    Posted by on in OpenCL, Altera SDK and the Parallella Post

    Hello, quite recently I received my back-ordered Parallella kit  from Adapteva, which I reviewed on this website here (review link). In its vanilla form the Parallella kit, which could be touted as one's personal supercomputer, requires a set of accessories to get it off the ground and up running.

    These accessories are either mandatory or optional. The accessories that I have acquired for use with my Parallella kit, so that it can be used in a headless HDMI configuration and a brief description of my experience in getting LINUX working is the subject of this blog post.

    Posted by on in DC Motor Controllers

    The L298N is a dual full-bridge motor driver available in a 15-lead multi-watt package that is popularly used in Arduino motor shields. The multi-watt packaging is required,  since this device can supply a DC current of up to 4A and has a total power dissipation of 25W. When run to it's limits and given the amount of heat this device is required to dissipate, it is not unsurprising during operation to see it tethered to a heat sink. This all sounded so interesting that I decided to check the device out. So an overview of this devices' characteristics and functionality forms the basis of this blog post.
