1.    Astable Multivibrator

A multivibrator is an electronic circuit used to implement a variety of simple two-state systems such as oscillators, timers and flip-flops. It is characterized by two amplifying devices (transistors, electron tubes or other devices) cross-coupled by resistors and capacitors. There are three types of multivibrator circuit， one of them is the astable multivibrator, in which the circuit is not stable in either state—it continuously oscillates from one state to the other. Due to this, it does not require input.

2.    TATP

A new terrorist explosive, triacetone triperoxide (TATP), has recently appeared as a weapon in the Middle East. TATP has been used by suicide bombers in Israel, and was chosen as a detonator in 2001 by the thwarted "shoe bomber" Richard Reid. It can be as or more powerful than military analogs. TATP is one of the most sensitive explosives known, being extremely sensitive to impact, temperature change and friction. Another peroxide-type explosive is hexamethylene triperoxide diamine (HMTD), which is less sensitive than TATP but still dangerous. HMTD is somewhat more sensitive to impact than TCPT, but both are very sensitive explosives.
