Description
Grow piezoelectric crystals from kitchen ingredients (cream of tartar + baking soda). Rochelle salt has one of the strongest piezoelectric effects known!
This adds a "made from scratch" dimension to the crystal radio project - demonstrating that the piezoelectric property comes from the crystal structure itself, not manufacturing.
Refer to piezoelectric-circuits-guide.md crystal growing section.
Acceptance Criteria
- #1 Acquire cream of tartar (200g) and baking soda
- #2 Make saturated Rochelle salt solution
- #3 Grow seed crystals (3-7 days)
- #4 Grow main crystal from seed (1-4 weeks)
- #5 Apply electrodes (conductive paint or foil)
- #6 Test piezoelectric response with LED/multimeter
- #7 Compare to commercial ceramic piezo
