Rabbi Aryeh Lebowitz

Havimah Chokas, are we concerned with noisy machinery on Shabbos?

And Rav Moshe has a famous, I don't know, famous, but he has a comment in Rav Moshe, that if you could hear it in the next room, then it's too noisy.

Okay, but these, so based on that Gemara, your Kelim Dumalacha for you on Shabbos, that is fine, unless it's very noisy, and obviously these photo frames are not noisy at all.

So what would be the problem?

So Rav Shechter Shelita, Morenu Rav Shechter Shelita, assumes that if a Malacha didn't start before Shabbos, if the entire Malacha is happening on Shabbos, meaning you may have set up the system by which this Malacha will happen on Shabbos, you may have set up the system on Erev Shabbos, but the Malacha didn't start on Erev Shabbos, that's where it's a problem.

And he bases it on a passage of the Rambam, which later discovered a passage of the Rambam that Rav Zevin wrote,

I actually wrote about it in Isham Vashitos, where the Rambam was me-yashav this stira by saying there's a difference between a mill and an irrigation system.

The irrigation system was already working on Erev Shabbos.

It was already doing the malach on Erev Shabbos, and it's just continuing.

The mill is grinding new wheat already.

on Shabbos.

So any time a new Malacha is happening on Shabbos, even if the system was set up before Shabbos, that would be a violation of Shvi Saskelem.

So it would follow that according to Rav Schechter, setting up a coffee machine or a digital photo frame would be Aser.

That it would be Aser.

So Rav Schechter does not like it.

He does not like these digital photo frames.

So again, in short, almost all poskim are mekil, Rav Shechter is not mekil.

Okay, question number two.

What is the halachic ruling regarding the Manhattan Erev?

I'm not an expert in Erevin at all, and I'm not an expert in the history of the Manhattan Erev, but even I know that it is a complicated history.
