Rabbi Aryeh Lebowitz

In fact, I was just in Brooklyn this past Shabbos at the shul of one of the great shuls.

G-d in America today, Rav Yisrael Reisman, and in his shul, they have such a scream in the lobby.

It didn't change very much, but it did change a little bit.

You know, rotated the flyer of my presence in the shul, you know, my Shabbos in the shul, with other flyers of other things.

So the question is, is there any problem with this?

So again, leaving out the sports scores in the news, just having...

Having that.

So having a screen that flashes pictures and fires and things like that.

I once wrote an article about coffee machines running on Shabbos, meaning if you set up your coffee machine to cook your coffee on Shabbos morning and you set it all up before Shabbos, is there any problem with that?

So there are a lot of issues that are unique to coffee machines, you know, shehiya and achzara and bishel and whatever.

But part of it is just setting up a machine before Shabbos that's going to be doing malacha on Shabbos, so on the surface.

And the background is that there is a concept in Hilchah Shabbos called Shvisas Kelim, to have your utensils rest from milacha on Shabbos.

Generally, though, the halacha is that we're not concerned with Shvitsas Kehlim.

The Mishnah, in the end of the first parakh of Masech Shabbos, has a makhlokas between the Beishama and Beis Hillel, whether you're allowed to set up Kehlim before Shabbos to continue performing malacha into Shabbos.

And the Shulchan Aruch, the Simen Ration and Beis, Paschans like the Beis Hillel, obviously, who say that there is no...

that the Kli can continue to do your work into Shabbos.

And the Mishnahis give examples of setting up an irrigation system, setting up a trap for an animal.

However, the B'reis and Shabbos Tafir Chas says that yes, you're allowed to set up an irrigation system.

However, what you may not do is you may not put wheat in a water mill going into Shabbos with the intention that the mill continues to grind the wheat into Shabbos itself.

And the Gemara says, well, wait a second, isn't that just Shavissa's Kelim?
