ANIMATED figures attached to the front of your bicycle will attract a lot of attention. Three types are illustrated, as well as a machine-gun noise maker.
As soon as the breeze strikes its tail, the goose flattens out and stretches its neck as though heading for new feeding grounds. The tail is connected to the neck by means of a wire link.
Small curved vanes of tin or aluminum turn the wheels. Scroll-saw the wheels and figure from thin plywood. The wheels have brass tube bearings to reduce friction.
This is an easy scroll-saw job, and should be mounted on a metal strip with some spring to it, to hold the feet lightly against the front tire.
The clapper should be made of lightweight wood. Wedge the clapper back when riding silently. Use the noise maker only on special occasions; to keep it working all the time will spoil its effectiveness and quickly wear it out.


FANS who would like to install a radio-on their bicycles so they can enjoy their favorite programs while riding around town or on short trips will find the inexpensive set described on these pages just,what they have been looking for. Fitting in a basket mounted on the handlebars, the battery-operated, four-tube receiver contains its own loudspeaker. It gives excellent results on local broadcast stations, and if iron-core coils instead of the air-space type specified are used this range will be increased.
Owing to the directional properties of a loop antenna, a 4' metal rod was chosen instead. The metal rod is connected directly to the grid cap of the radio-frequency tube. Both of the set's coils are tuned by a midget two-gang tuning condenser, which is mounted on the sloping panel by means of two right-angle brackets.
The antenna rod is insulated from the metal cabinet by a ceramic standoff insulator. The tops of these insulators are usually threaded, and the best method of attaching the aluminum rod is to thread it to fit, and screw it into the insulator. For greater signal strength, the set will have to be grounded.
