Gakken EX-System

Picked up this 70’s educational electronics kit from the market. It’s a Gakken EX-System that used electronic blocks (denshi blocks) to create circuits. Each block contains a component (or wire for signal routing) that join together to create the circuit.

There are some blocks and parts missing, but after throwing in some AA’s and a quick load of the first circuit (illuminating a lamp!) it worked!
