Replica 1 plus Users Manual Reading and identifying capacitors: It takes less time to read the values of the capacitors than to read the values of the resistors. The key is to understand and read the numbers correctly. Larger capacitors may have the values clearly printed on them. For example: 10uF = 10 Micro Farads Smaller capacitors however, may only have 2 or 3 numbers on them. For example, the 22uF capacitors say 22J. .1uF capacitors have the value 104 on them. This is similar to the resistor codes where the first 2 numbers are actual numbers and the 3 rd number is the multiplier code. So 10 X 4 is 100,000 and the value is in pico Farads (pF).

Converting it to a proper numbering format gives us the value .1uF. To make things easier, here is a list of the values on the capacitors used and the numbers printed on them. Power LED: Figure 10: LED pin internal diagram Looking at the LED there are two connectors, the Anode is longer and has the smaller connector inside. The cathode is the negative side. It has a shorter lead and a larger part inside the LED. The cathode is the negative post. Connecting is simple on the replica 1. The LED silkscreen on the replica 1 has the positive + marked. Simply put the longer anode connector into the positive side when installing. Ready to Begin Assembly:

Now that you have inventoried all parts you are ready to begin assembly of your replica 1. Step 1: Start with the resistors. Bend the leads on each side of the resistor 90 degrees near the edge of the resistor. Insert the resistor into its proper location until it rests flush with the board. They are not polarized so that can be installed either direction. While holding the resistor with one finger, bend the pins on the bottom side away from each other so that the resistor will not fall out and will stay flush on the board. Flip the board over and solder the resistor down to the board. Cut the extra lead length off and throw away.
