For my DT project i need 6 ideas of things to invent. The general theme is Handheld, that can be like ergonomic things and can cover a fairly wide range of stuff. I have things like a key ring and an ergonic univirsal tv remote(i can nick the electronics out a brought one), which fits your hand, also a toolbox. But i really cant think of my last idea, can anyone think of somthing not to hard to make...
Thanks for any pointers,
