Retro Space Invaders

November 17th, 2017

I think this is wonderful. Today I got to play with Gareth Bailey’s Space Invaders game – a quick hack, he claims, which he put together yesterday.

This uses an oscilloscope as an X-Y plotter to draw the graphics, harking back to the earliest days of computer displays. But historically, displays like this would usually have been driven by a mainframe, where as Gareth’s is driven by a Raspberry Pi.

And where do you get a couple of nice analog outputs from a Raspberry Pi? Why, from the left and right channels of the audio, of course….

Apologies for the quality of the video, but I thought this was worth capturing despite the challenging environment!

To create not a block, but an inline code span, use backticks: 

Here is some inline `code`.
