parts, we will quit going from left to right, top to bottom and begin to install
parts close to one another.
❒ 81. Install C1, a 10uF electrolytic capacitor. Notice this is the first
capacitor of this type. You want to pay close attention to the polarity
markings on this part. In most cases the negative (-) side is marked on the
capacitor, while the positive side (+) is marked on the parts layout. If you
fail to mount this component correctly, the part can fail as well as prevent
proper operation of your project. We will be installing many more of these
later in the project so remember this!
❒ 82. Install C4, a 10uF electrolytic capacitor. Check orientation!
❒ 83. Install C7, another 10uF electrolytic capacitor. Be sure it is oriented
correctly!
❒ 84. Install C9, another 10uF electrolytic capacitor. Again check orientation.
❒ 85. Install C16, a .0033uF ceramic capacitor (marked .0033 or 332).
❒ 86. Install C19, a .001uF ceramic capacitor (marked .001 or 102).
❒ 87. Install C15, a 10uF electrolytic capacitor (orientation!)
❒ 88. Install C20, another 10uF electrolytic capacitor. Again check its
orientation before soldering.
❒ 89. Install C29, a .1uF ceramic capacitor (marked .1 or 104).
❒ 90. Install C27, a .0033uF ceramic capacitor (marked .0033 or 332).
❒ 91. Install C22, a .001uF ceramic capacitor (marked .001 or 102).
❒ 92. Install C26, a 10uF electrolytic capacitor. Orientation!
❒ 93. Install C10, yet another 10uF electrolytic capacitor. Again orientation!
❒ 94. Install C21, even another 10uF electrolytic capacitor. Orientation.
❒ 95. Install C11, a 10uF electrolytic capacitor. (Yikes, do we have to tell
you again to check orientation? my typing fingers are gettin’ tired !)
❒ 96. Install C30, a 470uF electrolytic. This part is responsible for taking the
pulsed DC from the bridge rectifier and “smoothing” it out to a more level
DC voltage. That is one of the many reasons why you want to check
orientation before soldering.
❒ 97. Install VR1, the 7808 +8 volt regulator. This converts the raw DC from
the bridge rectifier and C30, which will still have AC ripple on it from the
pulsed DC from the rectifier, and finishes “smoothing” it out (regulation).
❒ 98. Install C25, a 10uF electrolytic capacitor. Orientation !
❒ 99. Install C23, a .01uF ceramic capacitor (marked .01, 10n or 103)
❒ 100. Install C36, a 10uF electrolytic capacitor. Again note orientation.
