tuesday, 1 day til move, 3 days til deadline
lots and lots and lots of worry.
had to buy a last minute addition, a PIR sensor from Active-robots.co.uk to go with project two, the proverb machine. the buttons were just too clumsy and wanted something a little less touchy. the PIR sensor should be really quick to connect to 5V, GND & an14 so that's good.

woohoo
finally uploaded sketch for wave shield onto arduino, works and everything.
hooray!
The sketch looks for the switch, when it's pressed it plays the files on the sd card. well, it should anyway. It plays a set of stupid and pointless proverbs - reflecting the aluminium slapping fortune teller sculptures' beginnings.
had to change the switch to make sure project was completed in time, instead of twitter through ethernet shield, now just going for a simpler microlever switch, with paddle adaption so that it will be triggered by people inside the room, rather than outside in internet space.
would still really like to do the twitter thing, and have the sketch in a draft state to do it, but realistically not going to get it all finished with everything else like log book and drawings and setting up exhibition space by friday afternoon. The plan is to place the twitter machine in a gallery setting sometime in the autumn, maybe in the 'da girlz' exhib?
as for project one, the repetitive sound one, in need of a power amo as the one i have is far too weedy. On testing it out in the space on sunday it sounded weak and feeble and definately not annoying. Need it louder, louder, louder and much more oomphier.
speakers will need gaffa taping as the connectors are a bit wobbly, plinths to house speakers still not here, hoping that workshop guys will have done them so I can get on an paint. Threy prob won't be, but one can hope. Have rediscovered that I am the world's most impatient person ever.

Saturn film
This is incredible, it's a film of saturn's rotation filmed from Hubble. It looks like a cartoon, almost not quite sure if it's real.
