content: I also see 2, 4 cell battery holders with what appears to be fibrous packaging tape on them and what also appears to be some kind of board with a card edge connector on it. Pretty snazzy. That heatsink looks like it does some serious business too! hahahahaha. I see people at Apex Electronics looking for parts to put in props all the time. They are clueless.

content: I see a relay bank used to generate the running light sequence, and a lot of junk PCB's cut and epoxied into tubes of acrylic in an acrylic case. Also a reed relay probably used to turn the power on and off. Batteries required, and the tape probably used to keep them in the holders so you would not need a retake of scenes because of poor contact.

content: QuoteOr a 78H05K like in my old pinnball machine of that era.Anyway what a dreamjob it must be to build electronic gadgets for the moviestudio.I am always stupidified when even in 2014 movies the prop time bombs use 7 segment LED displays and all ics are throughole parts like in the recent movie "non-stop"http://www.imdb.com/title/tt2024469It is as if there is a parts shop somewhere in Hollywood and they ask for a prop time bomb and they get this 80's model from the closet

Must have made a little noise when running, good thing the voices and effects were all added in post. Yes, 12V, a room with an actor, a script and a massive mixing deck to do it all........
