I've had many requests from TZ fans to help them build their own Mystic Seer. Below, I've provide some detailed drawings and in progress construction pictures. I will try to add additional information as I have time. Send me a note if you have any particular questions. First, I need to say that my MS is not really operational. That is, it does not dispense the fortune slips. It does however have a working/spring loaded lever and will collect all the pennies you put into it. Also, the napkin holders are spring loaded and hold the napkins rather nicely.
I used PVC sheet material for construction. Partly because I used it for constructing many parts of my robot but also because it is so easy to work with. My Mystic Seer will not fit over a Swami Machine.If you attempt that, you may have to use sheet metal and/or adjust some of the dimensions.I noticed that my drawing does not have the center point for the key lock. I'll have to update it at some point.
