I am going to give the kitchen timer in waterproof bag a try. I just hope the alarm shuts off automatically after a while!
For holder and placement, I'll see if I'll CNC mill a suitable piece of wood
The one I have does shut off after about 1 minute of really annoying beeping.
But if you can hit it with anything, the button will turn it off..
The egg timer, on the other hand, only rings once... And it looks super-cool sitting on the front beam.
