A simple build-it-yourself alarm kit.
Children of a certain age often have plans about being warned when their diary, door, or jewellery box is opened. A simple but functional alarm can be built from the transistors, resistors, buzzer and electronic baseboard provided, with a neat introduction to electronics along the way.
Please note: A 9 Volt 'D' battery required, not included. Also needed: a small pair of pliers (either with built in wire cutter, or a separate wire cutter, or an old pair of scissors will do for this if need be).
Recommended for tinkerers and builders ages 12 years and up.
Made in Germany.
