3D Design & Print: bits for my kitchen radio

I wanted to add a BlueTooth transmitter to KitchenPi

At last, a mini-project to exercise my [dubious] 3D design skills.

KitchenPi: an internet radio for my kitchen

We needed a radio in the kitchen to replace our Bush DAB/FM portable which has put in good service, although DAB reception in our area has never been great.

As space is at a premium, I wanted the new radio to take up as little space as possible.

So I came up with the idea of building something that would fit under the eye-level kitchen cabinets, behind the decorative molding.

The NJM2073D: an amp for the Pi

The NJM2073D is a low cost, easy to use, audio amplifier chip with a maximum power of about 2 Watts.

It can be used as a stereo amplifier for portable devices like a music player or a radio, and is available for just over £1.

I have a couple of Raspberry Pi applications that need audio, so this device looks like a good option.
