Introduction: Det Box 2!
Its the det box with a timer! I give 99% credit to let_it_out_org this project (mainly because he didnt put it into one cool project box).let_it_out_org posted this https://www.instructables.com/id/quotTimed_Soundiequot_or_quot12_second_sound/ instructable on how to make a 12 second sound grenade and I thought id make a video to show people how it works.
