 15. Install D4, 1N4148 silicon diode, above C5. Watch the polarity.

 16. Install R5, 1K ohm resistor [brown-black-red], above D4.

 17. Install D3, 1N4148 diode, right next to R5. Once again, don’t put it in

backwards just to be a rebel.

 18. Install R4, 100K resistor [brown-black-yellow], next to D3.

 19. Install R6, 470 ohm resistor [yellow-violet-brown], next to R4.

 20. Install U2, 555 timer IC under R4. Line up the notch like you did with

U1.

 21. Install C3, .1 uF ceramic disc capacitor [marked 104], just to the left of

U2.

 22. Install R10, 100 ohm resistor [brown-black-brown], to the left of C3.

 23. Install C2, 100 uF electrolytic capacitor, below C3. Follow the silk-

screen for polarity!

 24. Install R8, 1K ohm resistor [brown-black-red], below C2.

 25. Install C4, .1 uF ceramic disc capacitor [marked 104], to the left of C2.

 26. Install R7, 5K ohm potentiometer [orange top marked 502], to the left

of R10.

 27. Install C8, .1 uF ceramic disc capacitor [marked 104], above R7.

 28. Install U3, the last of the 555 timers, under R7. Line up the notch

again.

 29. Install C6, .1 uF ceramic disc capacitor [marked 104], next to C6.

 30. Install VR1, 5V low power voltage regulator, next to C6. Line up the

flat side with the flat spot on the board drawing.

 31. Solder in the 9V battery connector into pads P1 and P2. The black

wire goes into P2 and the red one goes into P1.

 32. Solder in the speaker to pads P3 and P4 using the included wire or

your own. It doesn’t matter what wire goes into which pad.

Okay, enough of all of this stuff. Time to test it out!
