This PDF contains general information on psi wheels and my voice activated psi wheel called audio psi that can be operated via your voice.
Why would this be useful you ask? Well! Because it allows the user to gather a group of people say for a traditional psi party where they do the normal psi party stuff to start with. Then you bring out this one which is sitting on the table and have the audience move it – at a distance – using only the power of their mind. Which, unknown to them, is actually powered by your voice when speaking in the direction of the device from a distance.
No, this is not a normal psi wheel and its a lot more reactive. It’s some freaky stuff.
Originally released around 2014, but only a few people ever saw this work.
