SoundBulb: light bulb and a speaker

A new multi-functional device called Soundbulb, lightbulb that has an 8 ohm speaker inside. These Soundbulbs also have a Bluetooth receiver that allows for wireless streaming of audio from a computer or cellular phone.

A Map that is also a Light

This device, which is simply called The Light, is an ordinary map that, when rolled up like a kid’s pretend telescope, will become a flashlight.

How does something like this work? First, the map is not an ordinary map, but two sheets of paper. On one of these sheets is the actual printed map itself, while the other is a cover sheet with two electrodes.

Second, simply roll up the map so the two electrodes meet, and this union turns the built-in LEDs on. This device is powered by a thin battery that fits in between the two sheets.
