Background to phosphor displays and analog oscilloscopes For all of you that have used analog oscilloscopes or other equipment with a phosphor display knows how beautiful the image can be from such displays. The color grading, which naturally occurs due to the persistence in the glow from the phosphor, also acts as a useful measurement on…

Computer rendering of the Earth and Moon
Modelling and rendering of computer generated imagery (CGI) have been a hobby of mine for some time. In my work as a scientist I have used this skill to model and animate devices, however I have also animated and rendered scenes just for fun and to learn new techniques. From my interest for astronomy and space-technology I…
Scanning Electron Microscopy (SEM at home)
This article is about my Scanning Electron Microscope (SEM) which I had at home for several years during the time I was doing my graduate studies. I later donated it to Ben Krasnow from California, USA, he is the person who runs the popular science/technology YouTube channel by the name Applied Science. During the years…
DIY – High Stability 10 MHz Frequency Standard
I decided to build my own Frequency Standard from a 10 MHz CFPT-126 TCVCXO (temperature-compensated and voltage-controlled oscillator) and a dsPIC microcontroller which handled an adjustable frequency division in software when enabled. This oscillator has a typical frequency stability of 0.5 ppm over the entire temperature range (-40 to 80 °C), however at a normal…
