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.
