Hi there,
I found this site and literally couldn't stop laughing....love it..:lol
I'm the guy who designed and built these detonators for the film and must say yours look really good!
and the bloke who thought it was funny, that it was a decision maker circuit
on the detonator was right!! it was partly the reason I used it, it made me laugh due to what was going on in the scene!
cant believe you figured out most of the parts...absolute genius!
just end by saying two things (maplin electronics) (RS components) u.k..!
