WIRELESS ON THE FINGER.

CANADIAN BOY’S INGENUITY

EDMONDTON (Alberta)

A boy of 18, named Cecil Henzell, of Edmonton, claims to .have built the smallest wireless receiving set yet heard of. It is built on a finger ring which fits the lad’s little finger, and was carved by him out of a solid piece of walnut.

The mount is in two pieces, the surface measuring about half an inch square. The contacts for securing to wave lengths are formed of tiny pins, with a small brasß lever. A tiny speck of galena forms the crystal cup, and a minute gold wire the “cat’s whisker.” The aerial is in the form of a body belt wrapped rounl the waist, and a ground wire is worn down the trouser leg, which is perfectly satisfactory so long as the operator stands on damp ground. Otherwise the usual type of ground wire is used, but the boy inventor is at work on a plan to enable him to übo his concealed ground wire at all times, thus making the set absolutely self-contained. Five people at once heard quite clearly a concert broadcast recently by the Edmonton ‘Journal,” though the boy’s home is five miles from the broadcasting station. Young Henzell, who is a jeweller’s apprentice by trade, first of all made a receiving set that fitted the case of an ordinary sized watch. Realising that he. could secure equally good results with an even smaller set, he decided upon the ring and this tiny set receives i shortdistance messages with the utmost clarity. \
