Having completed the frame, I need to design a handheld controller, suitable for controlling the trike. I’ve decided to use an Xbox style joystick as these are easily available and the Adafruit Eagle library already had them, saving me redesigning the package! I intend to make myself a dual motor controller on a single board […]
Having changed my degree title from Electronic engineering to Electrical and Electronic engineering, means that I have to take some power modules. While I don’t find mass power transfer particularly inspiring (HVDC links, the grid and power networks blah blah blah), I find small power conversions pretty interesting, the low power stuff that enables us […]
Well! Today, I didn’t feel like doing anything particularly productive so libraries were pretty much not an option. Instead, I decided to make a really simple oscilloscope which merely displays the current sample voltage and a trace of the samples on the screen using my ILI9163 and graphics libraries. The input voltage is specified from […]
As mentioned in the previous post (https://hsel.co.uk/2014/08/08/designing-a-trianglesquare-wave-vco-part-1/), the maths and somewhat lesser interesting theory will be discussed in this post! Now just as a disclaimer: I’ve just completed my first year of university and we do cover the shockley equation, we don’t however cover lambert W function and I don’t want to use an interative matlab […]
