Finishing off an indicator panel

Tuesday, July 30th, 2024 at 08:53pm

Five months I had an idea for an indicator of my dishwasher status, earlier this month I designed and ordered my first custom PCB, last week a bunch of custom PCBs arrived and today I have a final design (for now at least…) mounted to my kitchen wall.

The assembled PCB:

The green terminal block ended up being too tall for what I wanted, so that was removed. The three nylon spacers are what will be glued to the back of the faceplate.

It is not visible, but I found low profile pin headers, these keep the D1 mini as close to the PCB as possible, but without directly soldering it in place in case I need to swap it out.

This is all still too thick for a single faceplate so a spacer block is still needed, but as I now have a 3d printer I am not limited to the spacer blocks you can buy, I was able to design and print a simple spacer that also includes a channel for the power wire to pass through:

Final result:

I now need to refine the automation rules in home assistant. I’m thinking seomthing like red for power has been turned on, blue for dishwasher is using power then green for when the dishwasher has stopped using power and is ready to empty.

I will probably also set up another panel for my washing machine.
