The Pi Cap is here! Order yours today

You asked how to connect Electric Paint to your Raspberry Pi project and now we’ve got the answer.
The Pi Cap!

Connect your Raspberry Pi to Electric Paint and the physical world using the Pi Cap’s robust and precise capacitive sensors. Add touch, distance sensing and high quality audio to your Raspberry Pi projects. Whether you have A+, B+, Zero or later, the Pi Cap is compatible with any Raspberry Pi with a 40 pin GPIO connector.

Connect Electric Paint or anything conductive to one of the 12 electrodes to control sounds, video and more. Transforming physical inputs to digital outputs is easy with our fully featured libraries and our extensive online tutorials.

Features & Resources

We know the resources to support your projects are as important as the quality of the product itself. This is why we’ve worked hard to create all the resources you may need to get started. From tutorials, to project and code examples, to visual guides and an awesome Pi Cap features tour, you’ll have everything you need to get started with your project.

• High quality audio output
• Extensive tutorials and an easy startup experience
• Powerful Python and C++ libraries so that you can include sensors in your project
• User-programmable RGB LED and multi function button
• Prototyping area with GPIO breakout to add additional sensors or buttons
• Works with Raspberry Pi A+, B+, Zero and later (Any Raspberry Pi with a 40 pin GPIO connector)

Pi Cap Intro

The Pi Cap features tour walks you through the code examples that are supported by the Pi Cap library to give you an easy start to your project. Featured code examples include:

• Simple Touch – Get data from the Pi Cap showing which electrode has been touched or released
• Datastream-tty – Similar to simple-touch, datastream-tty continuously streams the electrode data
• Datastream-osc – Similar to datastream-tty, but streams OSC packets to a specified host over a network
• Polyphonic Touch MP3 – This example plays mp3 tracks in the tracks folder when electrodes are touched
• Text to Speech – Text files are synthesised (read out) by a computerised voice when you touch electrodes
• Button Utility – A single button press to prints Hello World! to the console, a double press reboots and a long press does a proper shutdown (avoiding corrupting your microSD card)
• LED colour spinner – Display code status, debug or start a tiny rave. Example code loops through a variety of colours – the source code shows you how to manipulate the LED colour.


We do our best to make sure we’ve ironed out any problems in the engineering and user experience of our products before they get into your hands. This is why before launching the Pi Cap we ran a workshop with members of our community to test out the functionality of the board, and to find out how people would use it in their Raspberry Pi projects.

We’re happy to say that our user testing workshop was a great success with some useful feedback and amazing project outcomes. We made sure to document the day so you can see the results yourself, and hopefully get some ideas for how you’ll use the Pi Cap in your next project.
