    Lift Loss Project 58 Build the circuit to the left. Cover the photoresistor (RP) and turn on the slide switch (S1). The motor (M1) should spin. If not, give it a push to get it started. Now uncover the photoresistor or get a flashlight and shine it on the photoresistor.

  • Page 4: Project 60

    Mind Reader Game Project 60 Build the circuit below. It uses a paper clip and a The object is for Player 2 to guess the location by switch off and on to reset the sound. 3-Snap Wire as “shorting bars”. placing one end of the paper clip on the 5-snap Player 2 then sets the 2, 3, 4 side and player 1 wire as shown, and the other end of the paper clip...

  • Page 5: Project 61

    Project 61 Don’t Make a Sound Use the circuit from Project 60, but now place a 3-snap wire and the LED (D1) as “shorting bars” under the paper sheet as shown on left. Setup: Player 1 sets the “Quiet Zone” by placing the 3-snap wire and the LED (D1) under the paper on columns 2, 3 or 4, leaving only one open.
  • Page 6 Mixed Up Music Project 63 In the circuit, the outputs from the alarm and music ICs are connected together. Build the circuit shown and then place the alarm IC (U2) directly over the music IC (U1), resting on two 1-snaps and a 2-snap. Turn on the switch (S1) and you will hear a siren and music together while the lamp (L1) varies in brightness.
  • Page 7 Project 67 Space Battle Build the circuit shown on the left. Turn on the switch (S1) and you will hear exciting sounds, as if a space battle is raging! The motor (M1) is used here as a 3-snap wire, and will not spin. Bizzare Blinker Project 68 The preceding circuit is loud and may bother people around you,...
  • Page 8 Wave & Watch Project 70 This circuit does not use the noisy speaker (SP) but instead uses a nice quiet LED (D1). Turn on the slide switch (S1), the LED flickers. Wait a few seconds, and then cover the photoresistor (RP), and the flicker stops.
  • Page 9 Project 72 Project 73 Current Splitter Light Up & Listen Turn on the switch (S1), the LED This circuit has four different (D1) and lamp (L1) are bright. types of output. Flip the switch This is an unusual circuit which (S1) several times.
  • Page 10 Little to Big Project 75 Place the fan on the motor (M1) and turn on the slide switch (S1), then compare this circuit to Project #31. Push the press switch (S2), the lamp doesn’t light now but the motor still spins. The lamp is dark because the 100W resistor (R1) limits the current through it.
  • Page 11 Project 78 Reflection Detector Build the circuit to the left. Place it where there won’t be any room light hitting the photoresistor (RP) (such as in a dark room or under a table), and then turn it on. The 2.5V lamp (L1) will be bright, but there should be no sound.
  • Page 12 Project 80 Laser Flasher When you press the press switch (S2), the integrated circuit should start sounding a very loud laser gun sound. The red LED will flash simulating a burst of laser light. You can shoot long repeating laser burst, or short zaps by tapping the press switch.
  • Page 13 Project 82 Spinning Rings Setup: Cut out the disc on page 29 that looks like the one shown here. Using Scotch tape, attach the disc with the printed side up on the top of the fan blade. Place the blade on the motor as shown to the left and below.
  • Page 14 Project 84 Race Game Modify Project 82 by adding the pointer as shown on the left. The paper should be cut from page 30 and taped high enough on the speaker so the pointer will stick over the fan with paper. Bend the pointer at a right angle as shown on the left. Setup: Cut out the grid with four (4) colors from page 30 and place it under the base as shown on the left.
  • Page 15 Project 86 Visual Volume Build the circuit shown on the left. Turn on the slide switch (S1), a police siren is heard. The loudness of the sound depends on how much light reaches the photoresistor (RP). Try partially shielding it or placing near a very bright light, and compare the sound.
  • Page 16 Project 91 Two-way Light Switch Build the circuit on the left. Note that two of the 2-snaps are left unconnected on one end because they will be used as switches in this project. If you connect the free ends of each of these 2-snaps both to the “high bar”...
  • Page 17 Project 93 This OR That Build the circuit shown. Notice that if you turn on the slide switch (S1) OR press the press switch (S2) the LED (D1) lights up. There is no partially lit state here, the diode is either totally on or totally off. While this may seem very simple and boring, it represents an important concept in electronics.
  • Page 18 Neither This NOR That Project 95 Build the circuit at left and test the combinations of the slide switch (S1) and press switch (S2). If you compare it to the OR circuit in Project 93, you can see the LED (D1) lights in the opposite combinations of that circuit.
  • Page 19 Project 97 Light Makes Light Build the circuit to the left. Cover the photoresistor, turn the switch on, and notice that the LED is on for several seconds and then goes off. Uncover the photoresistor and place the unit near a light and the LED will light. Cover the photoresistor (RP) again and the LED will turn off.

  • Page 20: Project 100-109

    Project 101 Project 100 Touch & Go Flashing Flare Build the circuit shown Wet your fingers with some on the left. The circuit water or saliva and touch them uses the Alarm and across points A and B several Space War ICs to flash times to hear some space war the LED (D1).
  • Page 21 Project 103 Fan Flash Energy Place the fan on the motor (M1). Hold down the press switch (S2) for a few seconds and then watch the LED (D1) as you release the switch. The LED flashes briefly but only after the batteries (B1) are disconnected from the circuit.
  • Page 22 Project 106 Music Alarm Combo Build the circuit shown and then place the alarm IC (U2) directly over the music IC (U1), resting on the three 1-snaps. Turn on the slide switch (S1) and you will hear a siren and music together.

  • Page 23: Project 110-119

    Project 109 Long Gone Light Push the press switch (S2). If the fan is off the motor (M1) (or flies off) then the LED (D1) will be bright. It takes a lot of current to spin the motor when the fan is on it, and the voltage drops because the batteries (B1) cannot supply enough.
  • Page 24 Project 112 The Dark Dimmer Turn on the slide switch (S1) and push the press switch (S2). If there is light on the photoresistor (RP), then the LED (D1) will stay on for a long time after you release the press switch. The energy stored in the 470mF capacitor (C5) keeps the controlling current to the NPN transistor (Q2) on even though the press switch was turned off.
  • Page 25 Project 114 Sonic Flasher Set the slide switch (S1) on, a space war sound plays and the LED (D1) flashes. Cover the photoresistor (RP) and press the press switch (S2) to change the sound. See how many sounds are programmed into the space war sound IC (U3).
  • Page 26 Project 116 Light the Motor Build the circuit and place the fan on the motor (M1). Depending on which of the switches (S1 and S2) are on, you can turn on either the lamp (L1) (Project #1), the motor (M1) (Project #2), or both together (Project #10).
  • Page 27 Morse Code Project 119 This simple circuit can be used for communication. Press the press switch (S2) in long and short bursts to make a pattern of light flashes representing the dots and dashes shown in the Morse Code table below. You can use Morse Code and this circuit to send secret messages to some friends in the room without others knowing what you’re saying.

  • Page 28: Project 120-126

    Light to Dark Project 120 Turn on the slide switch (S1), the brightness of the LED (D1) depends on how LITTLE light shines on the photoresistor (RP). The resistance drops as more light shines, diverting current away from the NPN transistor (Q2). Project 121 Power Shifter When you turn on the slide switch (S1), the LED (D1) is on...
  • Page 29 Project 122 Electricity You Can Wear Did you ever wonder why clothes cling together Snappy says: clothes when they come out of the dryer? Did you ever can cling together hear a crackling sound when you take off a because electricity is sweater? (If the room is dark you might even all around us.
  • Page 30 Project 124 Bending Water You need a comb (or plastic ruler) and a water Static electricity was faucet for this project. Run the comb through your hair several times then hold it next to a discovered more than 2,500 slow, thin stream of water from a faucet. The years ago when the Greek water will bend towards it.
  • Page 31 Project 126 Sunrise Light Cover the photoresistor (RP) and turn on the slide switch (S1). The LED (D1) is off, but if you wait a long time then it will eventually light up. Uncover the photoresistor and the LED will light up in just a few seconds.
