Junior Scientists Electrical Questionnaire for Home Made Kits
A DIY guide for youths to build an electrical questionnaire using printed quiz columns from newspapers. It details materials, board construction, nail-and-card strips, eyelets, and a four circuit setup with a buzzer or lamp, plus testing and assembly steps. The piece promotes hands on learning and clever wiring to avoid memorization.
Electrical questionnaire puzzle with eyelets and buzzer
A vintage instructional piece describes wiring No 20 to 28 B and S gauge eyelets from mag nets of an electric bell to form a quiz key card. Test probes and a buzzer identify correct eyelets, then secure with an eyelet tool and create interchangeable question and answer sheets for educational entertainment.
