Biscuits.

We forgot the biscuits.

Whilst you’re all pondering how that could possibly happen – and today, being the end of maker week, I had some really good biscuits, let me tell you – here’s what we did:

Above, the Think Club crew beavering away. I have absolutely rubbish photos of the incredibly intricate soldering work being done to assemble our advanced lights for Light Play. So I won’t show you the photos, but I will tell you about the lights, since they’re works of art. We have Trinkets – which are like half an Arduino, if that means anything to you – powered off a single 1.5V cell via a step-up board that works, as far as we can tell, via unicorns. The Trinket drives a handful of Neopixel RGB LEDs, and a couple of controls allow you to set the colour, or the rate change of colour. It’s all terribly neat and self-contained, and particularly pretty. Pictures next week, promise.

Meanwhile, we assembled the pendulum frame and finally got around to hanging the pendulums. Pendula. Penduloptera. Whatever:

What really surprised us was that our frame was clearly wonky. Like: properly out-of-kilter. With trepidation we offered up a spirit level to the cross-member, and found this:

Huh. Well, that’s fine, then. I guess.

The pendulum array now looks like this:

OK, so there’s one missing from the end, and the lengths aren’t sorted, and we need to tidy lots of things up, and we haven’t got the instrumentation in place, and we have yet to even begin the essential stage which is ‘flashing light optimisation’… but you get the idea. Suddenly, the undergrads revising for exams in the quiet work area just outside Think Lab went from wholly indifferent to ‘ooh, shiny!’ and started talking to us. Which was nice, and gave us a taste of how people might respond when they see this thing in place at the Faire next weekend.

So – huge thanks to the Think Club 0 crowd for their endeavours this week, they’ve done a heap of work and have been delightful company to boot. The bulk of the work for both projects is done; next week Andrew, Joe, Sarah and myself have a bunch of finishing-up to do, then… dun-dun-duuuuurrrrrr: Maker Faire UK. Woohoo!

We also seem to have a gigantic pile of biscuits to scoff. What a disaster that is.

A quiet day today, with family commitments reducing the turn-out. Nevertheless, Joe’s particularly proud of getting the colour-changing lamps to work. My still photo above really doesn’t do them justice.

We’ve assembled the two ends of the pendulum support structure. Look at the size of that thing!

We now have a working turntable design which is slow enough to look good. It’s a bit bodged but works surprisingly well, particularly since it relies on a chopstick as a key component. I’m unreasonably delighted by that.

Meanwhile, Chris was immersed in Sonic Pi, the Scalextric was briefly up-and-running, and Andrew’s done a heap of calculations around the pendulums, working out what notes we should go for and hacking my simulation code so we’ve had a bit of a listen. It’s much less irritating than it was.

Oh, and we’ve ordered another round of electronic bits, and most importantly restocked the biscuit supplies. With exciting new varieties, no less.

So tomorrow we’ve mass-production of turntables to arrange, lights to finish assembling, colour-changing light circuits to solder up, and pendulum bracing to sort. We’re hoping the Think Clubbers come back after their day off. Otherwise, a busy day will become a hectic day.
