Spirit Window – Presented at the Haunted Harvey House
Goal of the Spirit Window
This week we set out to make energy more visible than say a simple EMF meter would provide. To do this we created a dot matrix screen and added X / Y control from two antennas.
How the Spirit Window Functions:
The Spirit window works by lighting the LED’s and scanning the array of LED’s from left to right, much like how an oscilloscope works. The X antenna controls the line height the Y antenna controls line width. The Spirit Window makes changes in energy easy to see, rather than a static reading you see changes over time.
How the Ghost Adventures Spirit Window was made:
The original design of the Spirit Window used what is called a flip-dot display; however, the flip-dot display had several bad rows so the design was scrapped and re-done using LED’s.
The design was “old school,” using through-hole devices and two microprocessors for control.
This build took roughly 120 hours to design, construct, scrap, start over, rebuild, test and tune. The major components were the case, opposing mirrors, custom made circuit board for controller, and custom made LED array. The sub assembles and mirrors were laser cut and everything was safely fitted and fastened inside the hard shell case.
The final unit created spectacular full screen drawings and small pinpoint images.
