Shabbos with a Bang

The popularity of Smart Sensors is on the rise. As more aspects of ordinary life are administered by electronic mechanisms, many practical questions are raised about how observant Jewish life is impacted by the new technology.

This item features a summary
of halachic opinion regarding the use of Shabbos elevators and prepaid trains
and busses. It also surveys the halachic definition of creating “fire,”
and how poskim define the use of electronic devices and appliances on
Shabbos. This package includes an index with 25 copies of original responsa.
