Hi guys
here is my last project.
I've built a tron legacy costume for a special event.
The suit is based on EL panels + my power unit with arduino micro.
the batteries are Lithium ion and give more than 4 hours of continuous power.
The suit is controlled by a switch in my hand and with the identity disc on my back.
the identity disc is based on an arduino micro + 3 axis accelerometer + sound module + vibrating motor.
the batteries are lithium ion too and the battery life is near 3h in standby ("C ring" + outer ring powered in white) and 1h in continuous effect + sound.
Disc animation FX is triggered by magnets on my suit or a switch.
here are some pictures
the SMBS smart battery gauge
unlocking and reprogramming it with my specs xD
building the sequencer
the power unit of the suit with batteries, el inverter + sequencer
testing the magnets strenght of my suit to hold the disc in place:
the disc:
the battery level from the smart battery gauge
and the final result
