Howto: Build a DMX Terminator

DMX512 terminators are easy to build; you need no more than a 5 pin XLR plug, a 120 ohm resistor, and a little time. Holding on to them once you’ve built them is the hard part. Get down to the local DIY store and buy a engraving tool, and engrave the fact that this plug is a terminator, and that it belongs to you clearly on it. You’ll still “lose” them, but at least after a few years you’ll be seeing your terminators around the place, and be able to grab them back!

The only outstanding question is what power the 120R resistor should be? In the photo below, the resistor shown is a quarter watt jobbie, chosen primarily because it looked nice for the photo. Human nature being what it is, the previous set of instructions said use a quarter watt resistor, cos that is what I was looking at whilst writing up the page.

HTML5 Video

Until now, there has not been a standard for showing a video/movie on a web page.

Today, most videos are shown through a plug-in (like flash). However, different browsers may have different plug-ins.

HTML5 defines a new element which specifies a standard way to embed a video/movie on a web page: the element.

Advanced Audiovisual Processing

This course is for Year 3 BSc/BMus Students studying at Goldsmiths Dept. of Computing.


This page will grow as the course progresses. Details of assignments will be posted here as and when they are set. For more specific course information, you can check the department intranet.

The course will be taught almost entirely in C++. Don’t worry about this. We will be using some bespoke tools to make this a lot easier. You should find that in the beginning some of the ideas and processes are familiar to you. We’ll be going into a lot more depth as we go forward.

We will be approaching this stuff in two ways. First, we’ll be using some ready made objects that do everything for you and allow you to muck around. Secondly, you’ll be expected to make some of your own objects based on what you’ve learned. Throughout this process, you should pick up some great skills.

We will be spending the first few weeks exploring Audio Digital Signal Pro
