Teach-In 2004 (1) - "How to Apply Electronics Meaningfully". Our brand new educational series is specially written to introduce beginners and students to the exciting world of electronics. Our hands-on tutorial spans ten months in total, and offers you a hands-on opportunity to get to grips with modern electronic components in a variety of practical demonstrations.

Teach-In 2004 adopts the "systems approach" which is ideal for teaching younger students and electronics novices alike. This encourages you to make a practical start to using electronics devices in a "black box" system design rather than concentrating on the complex mathematics or physics associated with the parts. If you're new to electronics and want to learn more, Teach-In 2004 will be the ideal way to get started! Will also use microcontroller-based circuitry, preprogrammed for simplicity.

Be sure not to miss this electronics tutorial series, specially written for students, hobbyists and anyone wanting to learn how to use electronic components!

PIC Random LED Flasher - Enjoy the fun of an interesting and attractive pattern display! Our PIC-powered mini circuit drives yellow, red, blue and green light-emitting diodes to provide a dazzling flashing display. Perfect for novelties, decorations, toys, jewellery and more. The small circuit can even be worn as a badge or necklace.

Our fully detailed constructional article walks you through the source code creation, and of course all practical constructional details are provided to enable you to assemble the project with every hope of first-time success.

Anyone At Home? - This burglar deterrent device is battery operated and causes a mains-operated lamp (e.g. a table light) to switch on and off randomly, to give the impression that the building is occupied. All parts are p.c.b. mounted for ease and safety of construction.

Two circuit boards carry the small 4000 logic circuit and mains p.c.b. relay.

Cardboard Clock - An intriguing and novel way in which you can watch time passing by! The article describes the evolution of electronic clock circuits, including the Kienzle single transistor clock circuit.

Full constructional and assembly details are supplied, including all drawings and diagrams to enable you to build the Cardboard Clock from scratch. An interesting project for hobbyists everywhere.

PLEASE TAKE NOTE In the December 2003 issue, we said, Use normal thin card for the clock wheels as thick (art supplies) card may be too heavy and stop it. Use a rectangular file to make the grooves that support the wheels axles. Depth is correct when a screw laid in the groove is half buried. Point "D" is the 15mm horizontal section of suspension hook W2. Cement end B of the pendulum post (A1) to the backboard. For the pendulum rod start with a 1 metre length of 24 s.w.g. wire, and draw (stretch) it slightly, to straighten it. Before bending it, mark the bend points with a pencil. The letter p shows on which side to position the pliers, when making bends Q and R. When readjusting the coil table rely on the rubber band, and not on the bolt through hole E.

Practical Radio Circuits (6). Single-sideband and direct conversion. Our expert radio writer describes another superb receiving system for the set builder and experimenter. A 7 MHz (40m) FET amateur band receiver is included along with all practical constructional detail needed. Another excellent and challenging project for the EPE radio enthusiast!
