A really random one.
I need something to send in with DS to school that will beep at 10am on a Monday and 11am on a Tuesday. Ideally it would live in his tray in the classroom.
I can't find anything that exactly fits the bill. I think my options are give him a cheap alarm clock, where we set the time by hand, and pray that he'll remember to take it out of his bag (unlikely) or give him a vibrating watch that goes off at 10am and 11am every day of the week.
