Archi.TECH Smart house
Age: 10 - 12, priced around £29.95
This kit is a great way to experiment with being an architect and building a house.
It contains 20 electronic experiments and shows you how to make each one work. Use the modular building system to design a house, then install ten different electrical gadgets including flashing LEDs, a speaker, motor and light sensor.
Several different designs can be created, such as a castle with a drawbridge and moat, a treehouse with a pulley-operated trap door, or even a house-to-house tramway with a motion sensor and doorbell!
The kit comes with an activity book, giving step by step instructions on how to develop the designs, so you can experiment all Christmas Day!
