Maker Faire Exhibit - Weeks 3 and 4

Last week I made the raku clay bird ornament in which the device will be kept, unless I can make a better one before the faire. It was a really interesting process to follow, and Hilda, the potter who showed me it, said things sometimes randomly emerge with clay, not always what you expect. I like that idea, as opposed to 3d design where you try and go for an exact shape. Also it shrinks 10% when it's fired, and so any calculations as to size or tuning would have to be done through lots of different models and trial and error, which I don't have time for as she is now going away for a bit, and I won't have access to her kiln again until after the maker faire.

I'm not completely happy with the results of my first big process of making: it's a bit small and the "bird" only happened randomly during the slab rolling process. But still, it's functional and I put a lot of stuff in it, that I know will need to go in any subsequent thing I make as an enclosur…

Maker Faire Exhibit - Weeks 1 and 2

It's not very often you get a chance to work on such a varied project. The brief for the project in the previous post on this blog, but I thought it useful to put down some thoughts at this stage in it's preparation. Especially in case I get lost later on.
Last week I did the first parts: I wired together light sensor, piezo buzzer and an electromagnetic field detector and they are sending data back to an arduino that is now capable of "sleeping" - i.e. switching to a lower power mode.
There are lots of ways of getting it to fall asleep though, and I prefer no power to lo-power as Newcastle is not known for it's warm bright weather (for example - this week, according to the newspaper, sunset came to Newcastle at 4.40pm, and the average temperature is of about 4-5 degrees with showers half the time, leading me to think rain power may have been a better choice than solar).
To amplify all the recorded and generated sounds this device is beginning to produce, I got a …
