Just an idea, you can put an capacitor between the calc and the
rumble-pack. This will only let ac-currents through and will block
dc-currents. Don't know if you can use this (probably not) but you can
always try. I will think about it when i get home (i don't have internet
at home) and i'll get back to you.
