Pancake machine (6/7) – homing the pan

Hendrik-Jan is a student who just started his bachelor studies in electronics September 2019. Hendrik-Jan made us a pancake machine.

Hendrik-Jan made a special PCB for the control panel. The control panel is used to home the pan, see video below.

For the homing of the pan a sensor was used. Hendrik-Jan used an optical switch with a RC propeller to block the light. Although this worked reasonably well, the optical switch appeared vulnerable. Throughout the process of making the machine 4 sensors were broken. It was not clear why this happened. There are a number of other options. Like using a hall-effect sensor with a magnet for example, or he could have gone with a simple micro-switch.

This is the penultimate blog post highlighting the pancake machine.
