These renderings suggest a simple construction
project using plywood, a control knob on a shaft,
and a plastic prism on the other end of the shaft,
rotating in a hole cut out of a circuit board. No need
for tiresome electrical wiring; just paste a printed
copy of the circuit onto the board, and a printed coil
under a “sensor plate” such as the lid of a lunch box.
Connect the coil to the circuit by gluing the ends of
sewing thread or string, and you’re ready to search
for eloptic radiation on the psionic waveband.
