I'm not the biggest fan of shakers on most games, but this game seems to beg for one with cannon fire hitting the ship. I made my own control/power board for the shaker, and decided while I was at it to have a go at making the shaker too. I made one for a friend as well, but he decided to sell his game, so I have an extra if someone wants it ( $150 ). I know Pinbits used to make something like this, but last I checked I could only find some alternative expensive products.
I wanted to be able to tune the shaker, so I made the weights adjustable: you can adjust the amount of weight, position of the weight, and how long you want the shaker to run on activation. I think you'll get the idea from the picture.
It's a very satisfying effect when you hit the ship! Also triggers on extra ball, as it's tied to the ship flasher.
