This is a superb recreation of the electronics kit that Gakken produced back in the 1970's with electronic blocks (denshi blocks) so you could carry out experiments safely at home. Gakken started reissuing the kits in the early 2000's and now here is the Gakken Ex-System Electronic Blocks EX-150. The transistor board kit teaches you how electricity works and creative engineers will be able to customize and adapt it to all kinds of cool things.
The set includes an antenna, microphone and earphone, as well as the 46 electronic blocks containing transistors and resistors, and which can be combined to make 150 different experiments. Make an electronic alarm, noise buzzer, lie detector, wireless microphone, and many more gadgets. No special tools are required, just the spark of scientific curiosity.
The Gakken Ex-System Electronic Blocks EX-150 features:
- Electronic blocks: 46
- Includes blocks, circuit, antenna, microphone, earphone, test batteries
