Measuring Power Using a Current Clamp

This post shows hot to use a current clamp to measure current and power using an op-amp based rectifier, and A to D and the Raspberry Pi. This is an extract from the e-book on Interfacing the Raspberry Pi to Analogue Signals.

Connect 2 Custard Pi 3's to a Raspberry Pi and get 16 analogue inputs

The Custard Pi 3 plugs into the Raspberry Pi GPIO (A, B, B+ and 2) and provides 8 analogue inputs using the SPI bus. This post shows how you can connect 2 x Custard Pi 3 to a Raspberry Pi and get 16 inputs. (There is soldering required).

GPIO projects for the Raspberry Pi

This blog post summarises a number of sample projects for the Raspberry Pi GPIO and provides links to detailed instructions with downloadable Python code. These are great for students and those wanting to interface the Raspberry Pi to the outside world.

Custard Pi Combos for the Raspberry Pi

If a particular Custard Pi does not have all the right inputs and outputs, then it’s possible to combine more than one. This post looks at the various combinations that are possible. (It's a chapter extraction from the new book 'Raspberry Pi with Custard' which is available from Amazon.)
