List of Items:

 

  1. Strip board(PCB:printed circuit board) cut to 5 columns.
  2. 2: 100 uf 10v capacitors.
  3. 2 resistor: Green resistor: Band color brown, black, yellow. 300k
  4. Brown resistor: orange, black, brown. 10k
  5. ICI or a 555 timer.
  6. Q1:PN 2907 Q2:PNP 3905
  7. 680 pf capacitor
  8. 0.1 uf capacitor
  9. Triple A battery holder.
  10. small 8 Ohm speaker
  11. copper foil tape.
  12. thumb tack
  13. zip wire
  14. pencil
  15. 3 cut wire 6 centimeters
  16. Wire cutters
  17. Soldering Iron
  18. Box cutter

 

Setting up:  Step 1:Heat up the soldering iron to 700 degrees, make sure to have some water so you can soak the excess solder built up on iron.

 

Step 2:Take your PCB and then Put ICI timer in center of the board, with round circle facing the edge of the board.

 

Step3: Cut strips of wires and solder pieces in three places. Place components in specified slots (Follow the diagram.)

 


 

*Be aware when placing 100 uf capacitor that black strip is negative and blue side is positive so it should be positive, negative, positive, negative.

 

 

 

 

 

Terms to be aware of:

GND- ground Ground is negative terminal.

SP- is speaker.

Vcc- is positive side of battery.
