Smartest A4 Paper

This a prototype for a digital engagement that allowed a piece of plain paper to interact with content on a mobile device. Data was transferred from electronics embedded in the paper to the app via audio encoded message known as Chirps. This was decoded using the Chirp SDK. The circuit was designed to be only 3 mm thick and be embedded in the spine on the edge of the paper. Engineers were engaged and manufactures in China identified. Is it dead?

Hotline Pudding

Many agency's put out an eDM or microsite for the Agency to celebrate the season. We decided this year to do some thing a little digital and a little unusual. We made a singing Christmas pudding.

The pudding is running a BareCoductive development board. The code was substantially modified to play back a series of MIDI tracks. The MIDI tracks were re-encoded into a custom format to allow the main melody sequence to be played back by tapping the pudding. Using a capacitive touch sensor, a single wire connected to the pudding provided a good conductive interface.

The plinths - made up in my kitchen, housed an internal LED floodlight controlled by the MIDI sequencer gave active visual feedback and a small stereo amplifier provided a deep sound and pleasing haptic response.
