Pi Zero: adapting the USB socket

Although the Raspberry Pi Zero is about half the size of a credit card, the connectors stick out sideways, which affectively increases the boards footprint once connected.


To make matters worse, the USB socket is the micro version, so you need an adaptor if you only have a standard USB wifi dongle.


So in order to make a really small, headless Zero system, you need to do something radical.

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.

BirdBoxPiCam 2014: News from the Nest

The blue tits arrived at the beginning of March and continued to visit almost every morning for a few weeks.


However, they wasted too much time faffing around and lost their deposit. A pair of new comers arrived on Monday the 24th and took control.


This post provides an update on nesting activities and adds some technical details regarding operation and performance.
