Those last few parts are the power supply section of our kit, taking the raw
DC input to the kit and smoothing it out for all the circuits. Ready to move
on?
13. Install R3, 10k ohms (brown-black-orange). Resistors can be
installed in either direction but your kit will look better if you have all the
gold bands lined up the same way.
14. Install R7, the only 1k ohm resistor in this kit (brown-black-red).
Check the color code to be sure that the red stripe is really red and not
orange like the 10k's.
15. Install C8, 0.01uF ceramic disc cap (marked 103, .01, or 10nF). .
16. Install C1, 10uF electrolytic capacitor. Remember to watch the
polarity when installing.
The next part is mounted in standup fashion, meaning that one lead is placed
through the circuit board and the other lead is bent around and then placed
through the board. The part is placed upright rather than flat like the other
resistors we've installed so far.
17. Install R9, 2.2k ohms (red-red-red). The body of the part is placed in
the hole marked with a circle and the other lead is bent over to fit in the
other hole. Again, keep the lead lengths short and the part flush to the
board.
18. Install R2, 10k ohms (brown-black-orange).
19. Install R1, also 10k ohms (brown-black-orange).
20. Install C9, 0.1uF ceramic disc capacitor (marked 104).
21. Install C2, 10uF electrolytic capacitor (marked 10uF). Remember to
watch the polarity.
22. Install C10, 0.01uF ceramic disc capacitor (marked 103, .01, or
10nF).
23. Install R10, 10k ohms standup (brown-black-orange).
24. Install R8, 10k ohms (brown-black-orange). Again, mount this part
standing up.
25. Install R5, another 10k ohm resistor (brown-black-orange).
26. Install C7, 0.1uF ceramic disc capacitor (marked 104).
27. Install C5, 0.1uF ceramic disc capacitor (marked 104).
28. Install C12, the lone 4.7uF electrolytic capacitor. Again, watch the
way it's installed and make sure the positive lead goes in the positive
hole.
