Educational and fun electronic kits

The discovery of a great electronics project idea, its research, and implementation into kit form has always been the standard of excellence at Elenco. Electronics can be a lot of fun if it is presented in an interesting way. A wide variety of educational kits are available, ranging from the elaborate Micro-Master Computer Theory Kit to the ever-popular Power Supply Kit. These projects are great for classroom and home learning. Additional listings are available by special order. We're proud to show off our kits - and you will too!

Space War Gun Kit

Produces realistic sight and sound effects you'd expect in a space weapon. The 'gun' can be set for stun (single-shot) or rapid-firing modes. While firing, two LEDs visually indicate impulse frequency while an 8-ohm speaker transmits the audio tone. In both modes, a potentiometer easily adjusts output pitch or firing rate. What you will learn: * Clock circuitry * 555 and 556 Timer circuits * R/C Timing circuits * VCOs (voltage controlled oscillators

Model K-10

Part No. 3K8-110


0-15 Volt Power Supply Kit

One of the most useful, inexpensive transistor regulated power supplies you can build, this 300ma Power Supply can supply voltages with the necessary current to run transistor radios, portable tape recorders, electronic games, and a host of educational kits. This is a very usable device that will serve you well for many years. What you will learn: * Rectification * Transformer action * Filtering * Voltage regulation

Model K-11

Part No. 3K8-111


Automatic Siren Kit

At last! Here is an automatic siren that definitely sounds like the real thing. When switch S1 is closed, the siren continuously cycles through the complete high-low oscillation pattern. There is no need to open a switch at the 'critical' moment to cause the sound to decay. In addition, there are no components to adjust or alter. Put the circuit together, connect a 9V battery, turn it on, and you're in business. The output is suprisingly loud and piercing. Use it with the Burglar Alarm Kit as an attention getter, or for just plain fun. This kit can also be used as a code practice oscillator by removing one jumper wire. In either case, the Automatic Siren will give you hours of excitement and satisfaction.

Model K-13

Part No. 3K8-113


Christmas Tree Kit

This unique kit is a great holiday project and provides an attractive decoration as well. Flashing eight bright LEDs at random, the project produces a "dialing effect" with a novel approach in a traditional package. Can be hung as an ornament, displayed in window, or set on end for table or mantle. An attention-getter enjoyed the entire year! What you will learn: * Clock circuits * R/C timing circuits * LEDs * Duty cycles

Model K-14

Part No. 3K8-114


Hidden Tormentor Kit

Hidden Tormentor is a fun game you can play on friends. It emits a sudden burst of high pitch oscillation (five sec every two minutes) that when hidden, is very difficult to find. Your friends will go crazy tring to find it! Works by using a low frequency oscillator in conjunction with a high frequency oscillator. Lots of fun! What you will learn: * Oscillators * Positive feedback * Charging paths * Changing resistor values

Model K-16

Part No. 3K8-116


LED Robot Blinker Kit

Flashing a pair of LEDs at a rate of about two "blinks" per second, this project is a neat toy that teaches a great deal about electronics. The circuit is basically an astable multivibrator or free-running oscillator, and as such it is one of the more popular types in use today. Educational and entertaining too! What you will learn: * Free-running oscillators * R/C timing circuits * Switching transistors * LEDs

Model K-17

Part No. 3K8-117


Digital Bird Kit

There are all kinds of birds in this world, but no bird sounds quite like this one! The Digital Bird can do imitations - everything from a 'tweeting' canary to a silly chicken - all with the turn of a few pots. A great introduction to sound synthesis, you will learn quite a bit and have lots of laughs too. What you will learn: * Oscillators * Logic circuits * Transistor amplifiers * Voltage dividers

Model K-19

Part No. 3K8-119


Burglar Alarm Kit

This is an easy-to-build dual alarm control for your car, house, room, or even closet. After the alarm is on, the only way to turn it off is to open S1. It could a key switch if you prefer. Many connection types could be used for N/O and N/C switches. Complete with a large 9V buzzer. Many different uses are possible with this Burglar Alarm Kit. What you will learn * SCR (silicon controlled rectifier) * Diode operation * Alarm devices * N/O, N/C switches

Model K-23

Part No. 3K8-123


Metal Detector Kit

Find new money and old treasure by getting started in metal detecting. Simply place the circuit near an AM radio antenna, tune the radio between stations without static, and adjust R1 until radio static occurs. Next, turn R1 slightly further until static just stops. When L1 comes near a metal object, the radio prompts with static! What you will learn: * Oscillator circuits * Radio transmitters * R/C timing circuits * Voltage Dividers

Model K-26

Part No. 3K8-126


Pocket Dice Kit

Pocket Dice is a handy little project to be used with any game of chance. Since it uses CMOS circuitry, it has the advantage of operating off a 9V battery, thus is quite portable. LEDs "blink" rapidly when switch S1 is pressed. When released, each LED set "freezes" in one of six common die patterns. Startle your friends! What you will learn: * Clock circuitry * Presettable counters * R/C timing circuits * Logic NAND and OR gates

Model K-28

Part No. 3K8-128


TV/FM Oscillator Kit

This TV/FM Oscillator is great to experiment with! It will make channels 2 through 13 go 'bananas' when adjusted right on the channel. People will wonder what's wrong with the set if you do it secretly.! With this TV/FM Oscillator, you will learn many electronics principles. What you will learn: * RC tuning circuits * Switching transistors * Voltage dividers * Radio frequency transmission
