South Holderness Technology College came to see us today. Emma organised everything excellently and I was first man in this morning, as I then had to zoom off to Doncaster for an Exam board. I was printing my tweets again, and everything worked splendidly. (This means that I am probably due a session where everything fails in the near future…)
They were a great audience, and I promised some references:
You can find out more about the Gadgeteer here: http://www.netmf.com/gadgeteer/
If you fancy buying some hardware you can get the kits from Cool Components.
If you want to make your own 3D printer like Una you can get a kit from Ultimaker.
Charlotte told me about a competitor to my Twitter printer (or perhaps my Twitter printer is a competitor for it). The LittlePrinter puts things onto paper, and will have a mobile client that you use to configure it. However, everything is pushed from a cloud based server which is supported by the hardware supplier. When they go bust you lose everything, and it is hard to see how they can make money once they have got the profit on the hardware. That has already happened to my Chumby and my Nabaztag rabbit. My plans for my Twitter printer include a web configuration page so that the user can always control the device directly, rather than any kind of on-going requirement for support.
