Universal Cable Adapter
By Art Trauffer
Built into a typewriter ribbon case, this adapter permits over 50 combinations of cable connections.
WHEN the writer finished making this adapter he started to count the different combinations of connections that can be made with it, but when he reached 50 he gave up. Certainly, 50 is not the limit for this versatile and easily-made adapter. If you build one of these you will save much time and trouble when joining together various types of connectors in radio and electronics experimental and test work.

Edited by A. NEELY HALL
BIRDS ought to appreciate this latest design in apartment houses, built to resemble a Zeppelin. To make it, secure nine pieces of one-inch white pine and saw them into 10-sided partitions as shown in the drawing below, the middle partition being 12-1/2 inches in diameter and the others tapering down to 6 inches.
THIS lively game will give you all the thrills of knocking the daylights out of an enemy city with well-placed “demolition bombs” without the least danger to the bombardier, although the area below is bristling with antiaircraft guns.
The bomber (Figs. 3 and 4) slides on a revolving arm supported by a central post (Fig. 2) and is moved by hand until it is over target selected. By looking through the bombsight with its cross-wires the airman can get a direct line on target and release marble “bomb” by a hand lever.
Fun with an Old Spark Coil
By RAYMOND B. WAlLES
ALTHOUGH producing a spark only about three-eighths of an inch in length, an auto (Ford) spark coil can be made to produce a brilliant stream of sparks, about two inches in length, by interposing small flakes of graphite throughout the gap. This is easily accomplished by dusting flake graphite on a tacky varnish card through which are fitted two machine bolts or binding posts for contact with the secondary terminals.
Mechanical Flying GOOSE Decorates Radiator Cap
For novelty in radiator ornaments, you’ll have to go a long way to beat this mechanical flying goose. As you speed along in your car, an ingenious arrangement of mechanism in the bird causes it to straighten out and flap its wings to simulate a real live goose in flight.
WHILE your car is standing still this wild goose isn’t so wild. He perches sedately upon the radiator cap surveying the world with a glassy eye. But as soon as you start up and shift into high he flattens out his tail, stretches his neck forward and begins to flap his wings as if he were going somewhere, and going there in a hurry.

A BOY’S DREAM COME TRUE
Give a boy a tree house and he can have all the adventures of a safari in his own backyard.
For adventurous little boys, a tree house offers many delights. It is a hideaway, a place to store secret treasures, a camping-out spot. From it one can see without being seen. It can be reached by ladder only and it is relatively inaccessible to adults.
