# One may set an alarm clock before [[Shabbat]] even though it will make noise on [[Shabbat]]. <ref>The [[Shabbos]] Home (Rabbi Simcha Cohen, vol 2, pg 537) and Sh"t Maharshag YD 1:7(2) permit. However, Sh"t Igrot Moshe 4:70(4) only permits if it is not heard outside his personal room. See Shemirat [[Shabbat]] KeHilchata 28:29 (and 28:30 in new edition) who permits before [[Shabbat]] for mitzvah purposes setting a mechanical alarm clock that involves removing a pin (see there). </ref> See [[Making music on Shabbat]].

# It is forbidden to leave a bread machine on a delayed start timer to bake fresh bread on Shabbat because even if one does so the bread will be muktzeh.<ref>Divrei Dovid 4:21 explains that fresh bread cooked on Shabbat is muktzeh since the flour during ben hashemashot wasn't edible. He explains that it isn't considered gamru biyadey adam since 1) Since it wasn't baked before Shabbat it is considered like it was totally rejected (dachinhu byadayim). 2) It didn't start during ben hashemashot. 3) Nolad is more serious than other muktzeh.</ref>
