| + | [* black] The toaster has been deconstructed! |
|---|---|
| + | [* black] Included here are some notes on the device's functioning: |
| + | [* black] The spring loaded "toasting lever" used to start the toaster closes two circuits: the loop with the heating elements, and the timing circuit |
| + | [* black] The timing circuit is a physical latch built into a circuit switch, an induction coil (visible in first figure), and a potentiometer. |
| + | [* black] When the physical latch is closed, it prevents the toaster lever from going back while closing the circuit to the induction coil |
| + | [* black] The latch/switch is made of (ferromagnetic) steel, meaning that once this circuit is completed, the coil will exert a pulling force on the latch, urging it towards its open position |
| + | [* black] Eventually, the magnetic force will overcome that keeping the latch closed, and the toast lever and toast will pop up, and the circuits within the toaster will be broken |
| + | [* black] The potentiometer is controlled by the cook-time adjustment lever, which accomplishes that purpose by altering the current going into the induction coil, and as such, the force the magnet exerts on the latch |
