Build a radio, doorbell, and burglar alarm – all with no soldering!
There are actually 300 projects you can build with this, and it comes with a high quality instruction booklet that teaches electrical principles while providing simple step-by-step instructions. The directions are in full color and the projects are in logical order of increasing difficulty.
The electronics include resistors, capacitors, and special units like photo sensors, speakers, motors, microphones, etc.
I had a similar kit as a kid, but it looks like they have improved this model to make the parts easier to connect and the directions easier to follow. This is a perfect gift for a child or teenager who likes taking things apart to see how they work, or who has expressed an interest in electronics.
