6. Transmitter • Board: • The board is the base on which all the electronic parts will be soldered on. Kapi'olani Community College – KCCSTEM

7. Transmitter • Resistors: • Install resistors R2, R3, & R4. Solder and clip leads. • Resistors are not polarized so orientation is not important. • Resistors: • R2, 2.2M Ohm (red, red, green, gold) • R3, 330k Ohm (orange, orange, yellow, gold) • R4, 18k Ohm (brown, gray, orange, gold) Kapi'olani Community College – KCCSTEM

8. Transmitter • Resistors: • Install resistors R5, & R6. Solder and clip leads. • Resistors are not polarized so orientation is not important. • Resistors: • R5, 33.2k Ohm (orange, orange, red, red, brown) • R6, variable (the other “blue-looking”) Kapi'olani Community College – KCCSTEM

9. Transmitter • Resistors: • Install resistors R7, & R8. Solder and clip leads. • Resistors are not polarized so orientation is not important. • Resistors: • R7, 33 Ohm (orange, orange, black, gold) • R8, 680 Ohm (blue, gray, brown, gold) Kapi'olani Community College – KCCSTEM

10. Transmitter • Diode: • Insert diode D2 & D3. • Diode is polarized. Install with white band oriented as shown. • Diode: • Look at the PC board to see the direction of the white band. • Solder and clip leads. Kapi'olani Community College – KCCSTEM

11. Transmitter • Capacitors: • Install capacitors C5, C6, & C7. • The capacitors are not polarized. • Orientation is not important. • Capacitors: • Solder and clip leads. • All of these capacitors are all 47 micro Farad. Kapi'olani Community College – KCCSTEM

12. Transmitter • Switch: • Install switch as shown. • IC Timer: • Solder all eight leads. • Do not clip leads. • Insert all 14 pins of the socket, notch is pointing up. • Make sure all pins on the socket & switch go through the board before soldering • Socket will snap in to place. • Do not clip wires. Kapi'olani Community College – KCCSTEM

13. Transmitter • LED: • Install red LED in D1. • The LED is polarized, the long lead wire is positive. Look at the PC board for correct alignment. • LED: • Insert flush to board. • Solder and clip leads. Kapi'olani Community College – KCCSTEM

14. Transmitter • Capacitors: • Install capacitors C1, C3, & C4. • The capacitors are polarized. The side with the white band is negative. The positive lead is longer. Look at the board for +/- signs. C1 fits inside the drawn circle. • Capacitors: • Solder and clip leads. • All of these capacitors are all 47 micro Farad. Kapi'olani Community College – KCCSTEM

15. Transmitter • Regulator: • Install the 5 volt regulator into U2. • The regulator is polarized and should be installed with the flat side facing away from the switch. • Do not push flat to the board, allow the regulator to stand up on the board. • Solder and clip leads. Kapi'olani Community College – KCCSTEM

16. Transmitter • Speaker Jack: • Install 2 pin speaker jack in J2. • Insert with longer leads on top of the PC board and solder shorter leads on bottom of board. • Speaker Jack: • Do not clip any of these leads. Kapi'olani Community College – KCCSTEM

17. Transmitter • Transmitter: • Install transmitter module in U3 with the metal can facing the outside. • Solder and clip leads. Kapi'olani Community College – KCCSTEM

18. Transmitter • Battery Clip: • Push 2” of battery clip wires down through the inner strain relief holes. • The red lead goes through the hole near the B+ hole and the black lead goes through the inner hole near the B- hole. • Battery Clip: • Push the bare ends of the wires back up and through the B+ & B- holes. • Leave small loops and solder the bare ends on top of the PC board. • Pull the wires tight to remove the loops. Kapi'olani Community College – KCCSTEM

19. Transmitter • Antenna: • Insert bare end of the antenna wire into smaller hole from under side. • Solder on top of the PC board and clip lead. • Antenna: • Push free end of the wire up through inner hole and pull tight. • Bend the wires to form 90 degrees for best results. Kapi'olani Community College – KCCSTEM

20. Transmitter • Capacitor: • Install capacitor C2 flush to the PC board. • This capacitor is not polarized, so orientation is not important. • Insert in outer holes, leaving the inner holes unused. • Solder and clip leads. C2, 0.01 micro Farad capacitor. Kapi'olani Community College – KCCSTEM

21. Transmitter • Thermistor: • Install thermistor, R1. • Solder and clip heads. • The thermistor is not polarized, orientation is not important. Kapi'olani Community College – KCCSTEM

22. Transmitter • 556 Timer Chip: • Install the 556 timer chip. • The pins are flared out, so you may need to bend them slightly inward. Make sure all pins enter properly into socket. It should sit flush.. • Make sure the notch is facing up with the notch in the socket. Kapi'olani Community College – KCCSTEM
