Circuit Blox 395 Projects (66 pcs)

395 Electronic Projects a Glowing LED FM Radio

These colorful building blocks have electrical components inside them that, when assembled properly, create circuits that illuminate lights, create sounds and spin a motor and fan! Conduct 395 experiments, including a real working FM radio. Features resistors, capacitors, transistors heart & star LEDs and more!

All parts are compatible with your existing building bricks and the other E-Blox product lines including Power Blox. Requires 3AA batteries (not included). For ages 8+.

How do Circuit Blox Work?

These blocks have a copper pin inside the top stud and socket underneath. When you stack up one block on top of another, the pin on the bottom block plugs into the socket of the top block allowing the electrical current to flow from one block to the other. Circuit Blox blocks the need to be connected to a circuit (which begins at the positive terminal of the battery block and ends at the negative terminal). When the circuit is complete, electric current flows from the 3 AA batteries through the component blocks, causing them to either light, make sounds or spin a fan then continues its journey to the negative battery terminal.
