We hereby announce to the public that electronic devices whose use activates or increases the electrical current or digital notations, and the like, are prohibited on Shabbos.
One must beware not to rely on contrived heteirim based on sofek psik reisha or grommo which are highly questionable.
And in the merit of keeping Shabbos, may we be redeemed very swiftly.
