Egg Timer

 is a miscellaneous item in Fallout: New Vegas.

Characteristics
Egg Timers are a component of the Time bomb (Explosives 50), created when combined with duct tape, dynamite(5), and scrap electronics(2).

Egg timers can be found rarely on merchants, in containers, and on dead gang members such as the Viper Gunslingers. One of the best places to find them seems to be from Powder Gangers around the NCRCF and its surrounding Powder Ganger raid camps, which are also a good source of dynamite.
