You can see more details here, though you can't book tickets yet.
There will be lots of fun things to do. I'll be running two workshops - Making the Shrimp and tworse.
Making the Shrimp
You'll need a laptop with a spare USB port and version 1.0.x of the Arduino IDE installed - or you can use a Raspberry Pi!
You can read about past workshops here and here.
Link up a Raspberry Pi to An Arduino (or Shrimp), and program them to flash out Tweets in Morse Code! It's a chance to polish your Python and sketch-writing skills! You can read a bit about the tworse project here.
You'll need to bring your own Pi and Arduino, or a Pi and a Shrimp if you made one in the earlier workshop.
I'll be publishing a detailed guide to what you need for the tworse workshop in the next few days, but if you have any questions just post them in a comment below. That way we can share the answer with everyone.
