TheHip - swinging monsterand other saltation design are popular holiday novelty or gag gift . You ’ve probably seen many of the different version at a store in the center , at the flea market or ontelevision . You activate them by doing one of three thing :
When activated , the image begins moving in time to a popular tune that come from the floor of the figure . Instead of having build - in music , some adaptation really dance to the music from your ownCDplayer orradio .
In this article , we ’ll spread out up the monster and take a tone deep down . What makes the music ? How does he move ? How do his eyes alight up ?
The Body
The terpsichore devil is an amazing example of graceful engineering science . It actually does everything using a exclusive electricmotorand somegears . In the following picture , we have absent the wear and outer plastic shell to look at the inherent framework :
When the button on the base is pressed , the song " Monster Mash " begin to play . After a second or two , the motor ( Figure 2 ) begin to reel . It spins in one counseling , then changes direction and tailspin in the other counselling in time with the euphony . The shaft of the motor is connected by a rubber bang to a larger wheel . Using a large wheel gears the midget motor down enough to match the timing of the music .
A metal shot connects the big rap - driven steering wheel ( soma 3 ) to another wheel . As the motor whirl the belt - drive bicycle back and off , the motion is channel to this second rack . It has a plastic boss ( form 4 ) that fits into a long expansion slot on the interior of the monster ’s back and works like acam . The freak ’s back and front body control board are link up together and attached to the frame by two metallic element pins ( Figure 5 ) that leave them to move back and forth on the physique . As the boss move from side to side within the one-armed bandit , this movement translates to sideways apparent motion of the entire body .
The Arms
The arms each have a perpendicular credit card tab attach just below the elbow roast . ( physique 6 ) A metal pin that is connect at a slight slant to the side of the eubstance frame goes through a hole at the top of the tab . As the behemoth ’s body moves from side to side , the pill slides up and down on the pin . This makes the forearm move up and down .
The inner bottom of the front and back body panels have molded plastic gearing tooth ( Figure 7 ) that check into similargearsat the top of each wooden leg . ( design 8) Each leg has a metal peg through the wooden leg where it enters the boot . This allows the legs to move from side to side . As the body motivate from side to side , the gears cause the leg to move in the diametrical instruction .
The Eyes and the Base
While the motor and gear are cause the fiend dance , two greenLEDsmake his eyes light up . ( Figure 9 ) The LEDs are connected to the circuit control board in the base of operations that controls everything . pulse of current are direct to the LEDs to sour them on shortly . This clear them flicker in time to the music .
The root word of the monster ( Figure 10 ) holds the circuit board . ( Figure 11 ) The circuit panel contains a tinyintegrated chip ( IC)that is the brains of the monster . This chip has the song encoded in it and synchronizes the movement of the motor to the medicine . It does this by alternating the stream of current to the electric motor so that the motor spins in one direction and then reverses and tailspin in the other direction .
Five yoke of wires run from the circuit control panel to all of the other components . They are :
This little verbaliser in the al-Qa’ida reproduces the music sent to it by the integrated potato chip .
