Prop Interactive Water effecet lamp


For the larp Do Androids Pray? we wanted to recreate the companys corridor scene from Blade Runner 2049 where some beautiful water light seemed to follow the persons who walked up the stairs.

I thought that it would be doable using multiple water effect light and dim them up when movement was detected.


I purchased some cheap water effect lamps of eBay and took them apart to inspect. The LED was hooked up to some mosfets, så I just removed the resistor leading to the original MCU and hotwired some leads to my own MCU.


I drilled out a small cut out for a 3 pin header an glued it into place and put a PIR module in.


The whole assembly kind of look like it’s original except an exposed PIR module.
