DIY Alarm making electronics kit

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.
