The first new patent pending BrainyWires Crystal Radio detector and amplifier kit is now available. Electronic components snap into place on chrome steel balls through strong neodymium iron boron magnet disks placed at ends of clear plastic rods and the corners of clear plastic panels. Use the clear novel design as a work area amusement piece. Kids ages 5+ can learn electronics while having fun connecting resistors, capacitors, diodes, inductors, and transistors in three dimensions.

The visual triangular variable capacitor is uniquely designed with the magnetic field of a nib magnet traversing and gently pressing two aluminum plates into a top steel plate.
