Yes, yes, I know I’m a stuck record about this, but: you only have a couple of hours left to back Mirobot. The Kickstarter hit its last stretch goal last night, so the full package now includes the line-drawing robot, obstacle detection, line following and a speaker.
I’m delighted for Mirobot’s creator Ben Pirt, and looking forward to the production run later in the year.
Stand-up mathematician Matt Parker and a team of volunteers build a functioning calculator out of dominoes, because… er… well, because they worked out how they could.
This has been festering in my pile of ‘unfinished hobby projects’ for longer than I’d care to admit, but just before I gadded off on holiday last month Matt prodded me with a very pointy stick. I’m delighted the film is finally seeing the light of day.
The film follows the domino computer build weekend at Manchester Science Festival with all its up and downs, and while we did try to explain how it works… well, turns out that’s quite tricky with hundreds of people milling around and thousands of dominos ready to fall over at a moment’s notice. So you might also want to check out this Numberphile film in which Matt explains the circuit with a little more care:
The team have also put together some worksheets, and can provide schools’ workshops (and dominoes!): think-maths.co.uk.
Elin also has a great bunch of stills of the weekend over on Flickr. Here’s one now. Note the breaks in the circuit during building, so an accidental fall doesn’t destroy the whole thing. There was a heap of work and expertise involved in building this thing, it really was a remarkable effort.
