Caian coffee

There’s a nice post about the coffee pot webcam on the Gonville & Caius College website this morning. Thanks, Lucy!

Retro Space Invaders

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!

All you need is Lovie?

Last night we went into London because the kind people at the Lovie Awards, the European branch of the (rather better-known) Webby Awards, had been good enough to give me an award, mostly for the work that friends and I had done in creating the first webcam.

I was a bit embarrassed about this, partly because I didn’t think I deserved it, and partly because of the name, but I got over the latter, at least, when I discovered that it’s in honour of Ada Lovelace.

Anyway, the tradition is that you have to give a little speech containing the word ‘Love’. The other tradition, which nobody told me, is that the speech should be about 30 seconds, which is why I look a bit more flustered than usual here! I was trying, not very successfully, to edit my speech on the fly. But I got away with it because mine was the last award of the evening.

It was a great and responsive audience, which, sadly, you can’t hear on this video.


Sean Riley creates the Computerphile YouTube channel, which has clocked up nearly a million subscribers, and produces some great stuff, especially for the geeks among us.

I had fun talking to him about the early days of the Trojan Room Coffee Pot.
