Solar Call (charge-discharge) (2021)

A solar-driven sound installation that charges electricity generated by a solar panel and produces a ‘call’ when it releases the charged electricity. It consists of multiple units, and on each of them, an electromagnet is connected to a charge-discharge circuit and rings a specially designed/tuned bell when electricity is fully charged into a capacitor.

The calls are influenced by the amount of electricity charged, which differs depending on what happens in daily weather: under strong sunlight, the intervals are short, and the calls are more frequent, under clouds or other elements that shade sunlight, the intervals are long and the calls become infrequent.

At night times, they become totally silent. The core part of this piece, the charge-discharge circuit, was made following the 2011 Fukushima Daiichi nuclear disaster and developed into several different works.

Makoto Oshiro is a Tokyo-based performer and artist. His primary medium is sound, but he also combines other elements including light, electricity and movement of objects.

In live performances, he uses self-made tools and instruments that are based on electronic devices, everyday materials, and junk.

His installation work handles sound as a physical and auditory phenomenon, and focuses on characteristics such as vibration and interference.
