Cospfail tech.

Think of portals.

Good…

Hell, yeah! Two batteries! put them wherever you want, cos voltages add no matter what.
Also, it was said to me that the person who “designed” this, was in his second engineering year. O_o

I have complained before about how cosplayers take leds and EL tech like it is something new and groundbreaking where it has 20+years of commercial aplication. Some days, after seeing this, I can’t decide if I want to make an advanced led ligting course, or if it’s just a waste of time
