The design was very much influenced by the early thoughts on the topic of <i>capacitive touch</i>. I would have installed all the technical components in a [https://www.instructables.com/Dead-Bug-Prototyping-and-Freeform-Electronics/ dead bug] fashion, disappearing into the flush socket of the wall, if it hadn't been for the idea of realising the entire backend as a PCB in the front. However, when the idea of touch input gestures was dropped (because this contrasted with highlighting mechanical devices), all that was left were components that logically belong to the backend. Yet, having everything fit tightly into the cover of the switch makes debugging very easy. By removing it, all the connections are accessible. So the transfer from breadboard to a PCB was the only logical consequence. | The design was very much influenced by the early thoughts on the topic of <i>capacitive touch</i>.

Before going into detail about the actual layout or so-called floor planning, I would like to add a few sentences about the look. The new subject shifted the focus slightly to more technical/constructional aspects, which is why I felt the need to pay extra attention to the graphical appearance. Since the ESP module rises above the other components, it was clear that it would have to be given appropriate treatment. Thus, it will be duly honoured by the Wifi Prayer ( | Before going into detail about the actual layout or so-called floor planning, I would like to add a few sentences about the look.

Since the ESP module rises above the other components, it was clear that it would have to be given appropriate treatment. Thus, it will be duly honoured by the <i>Wifi Prayer</i> (see sketch below) on the final design. (Well, it won't fit entirely on the plain, but its praising hands.) | ||

The prototypes shown in the picture above are only some of those I did. To be honest, I ordered another six PCBs right after receiving the first batch because in the meantime I already improved my design slightly. Also, I actually wanted to have a black solder mask, which is not available at aisler and that is why I ordered a third batch (again with some minor improvements) at [https://jlcpcb.com J@LC]. Luckily I realised the design as one layer only | The prototypes shown in the picture above are only some of those I did.

Luckily I realised the design as one layer only because there has been a special offer of aluminum PCBs and those do not support multi-layer designs. | ||
