Description
Build your own sound recorder by engineering a frame from plastic grid boards and pieces. Next wire the voice module and speaker to the battery box and securely attach the parts to the frame. Wire the main switch into your circuit and secure the wires per the instructions.
Young people learn how sound waves work and how a voice recorder uses a hard magnetic material as a carrier and uses the remanent magnetic properties of the magnetic material to record the sound signal on the carrier.
The main parts in this STEM project combines a mixture of:
- Speaker
- Voice Module Chip
- Battery Box
- Screws
- Plastic Grid Parts
- Wiring
Difficulty Level 7/10
