Snap Circuits Jr — 100-Project Electronics Starter Kit

Build 100 working electronic circuits without soldering — radio, alarm, LED flasher, fan. Real electronics, zero frustration.

Every circuit in this kit obeys the same laws as the circuits inside every device you own. Ohm's law, Kirchhoff's laws, capacitor charging curves, transistor switching — these snap together the same way your phone's PCB does, just at a scale you can see and modify. The difference between a child's electronics kit and a professional engineer's work is not the physics — it's the scale and manufacturing precision. The physics is identical.

100 different projects: AM radio, burglar alarm, doorbell, motion-triggered light, audio amplifier. Each one teachable as a physics concept: resistance, capacitance, inductance, amplification.

Includes: 30+ snap-together modules · Project guide with 100 experiments · Theory card for each project explaining the underlying physics

Ages 8+. No tools required. Ships within 7–14 business days.
