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 alar m 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. Show more
