A new pocket-size drum machine and synth called Bitty has been launched.
The small instrument is the work of manufacturer Curious Sound Objects and comes with a speaker constructed from aluminium that promises to go a lot louder than you might expect from something of its size.
It runs on just a couple of AAA batteries and allows users to play drums and melodies either manually or using a number of pre-set patterns. The machine also allows users to change the tempo of the 12 bit sound it outputs.
In order to add different sound packs to the machine, users just have to connect it to their computers via USB and upload them.
You can find more information on the machine via the link below. It's currently at the crowdfunding stage of its production.

A long-lost '70s synthesiser called the Resynator is the subject of a forthcoming documentary which is also seeking crowdfunding.
