Magnets for Melon Halves
8x magnets are used to join the top and bottom parts together. This allows the top to be removed to allow access to the circuit.
The two parts feature four 1/4in diameter cavities for fitting the magnets.
- 8x Magnets 1/4in diameter - 1/8in thick
Use a drop of super glue to permanently secure the magnets to the top and bottom parts.
Take note of the polarities of each magnet. Use a marker to label the north/south poles for reference.
