About the Designed by Aravinth PCB

Designed by Aravinth is an open source PCB design by AravinthPanch, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 220 × 150 mm, with 25 components from 23 distinct parts.

Other key parts include the DSP-MODULE_IDC_J3, MCU-MODULE, ECG-MODULE, DSP-MODULE_IDC_J4 and PROTO-MODULE. By type, the board carries 8 test points, 7 ICs, 4 connectors, 3 resistors, 2 jumpers and 1 diode.

It belongs with the audio designs in this gallery.

From the project

An interactive New Media Art system to translate the heartbeat of the visitor to an artistic form of sound and light in real-time.

araBeat is an interactive new media art developed for the artistic sonification of Electrocardiogram (ECG). It is a complete system that consists of modules of ECG, DSP, MCU & Motherboard.

araBeat captures ECG of human Interactors through two gel-less electrodes, identifies the QRS complex of ECG, calculates the time difference between the R wave peaks and using Audio DSP, it synthesizes high & low frequency sound in realtime, which is synchronized with the heartbeats of the Interactor.
