Hi Edward, I found a timer/pillbox (round, about 3 inches in diameter) at Rite Aid drugstores. You can remove the pillbox portion. I used a hot skewer to poke a hole in the timer so that a thread could be pulled through; it can be worn as a "necklace". The timer does not have to be constantly reset. My mother wears this, and it "rings" every two hours to remind her to take her medication. It works well. If you can't find it, I will be glad to send you one. Let me know.
