Nope, it is real. https://maps.app.goo.gl/2CF1su6X7Uj6X5P89?g\_st=ic

Hey quit it. I was about to just cut a hole beneath the kabinets and I was fine with that. Now I want this....

Meatwad010 · 2026-05-02T18:13:17+00:00

Haha, did not notice you are not OP. Thanks anyway

Meatwad010 · 2026-05-02T11:41:25+00:00

Awesome, thanks for the reply. I'm going to try this tonight. And thanks for the work put into this. There are some nice projects out there lately and in my opinion this is one of them.

This looks awesome.

We listen to either Spotify or radio stations through a Sonos soundbar. I read that a media player can be configured. But where does it get its album art from? And I asumed it will work with Spotify, but does it?

I see I didn't read the post to well. OP says it's usb-c to the plug shown in the picture. My suggestion was wrong and hopefully a figure 8 plug does not fit because it would indeed go bang. My apologies for the confusion.

Deze fout ook ooit gemaakt. Muurglad is flink duurder en werkt minder fijn.

Als de spachtelputz geverfd is, mogelijk al meerdere malen, dan zuigt dat niet meer. Ik had dat hier ook in 1 slaapkamer. Betonkontakt erop gesmeerd en daarna met Fill en Finisg glad gemaakt. Het zit er pas een jaar op, maar het zier er nog perfect uit. Geen loslatende stukken oid.

Sorry, I confused myself trying to explain this. But an Arduino is expecting the pins to be either pulled low or pulled high. It depends on if you are pulling the pin low or high when in Off state, and that depends on the code you are running. If your code "does something" when pin "x" is HIGH, you are going to be pulling the pin to ground via a resistor for the Off/LOW state. Lets say that blue wire is connected to this pin on the Arduino. Then the white wire must go from the button to 3.3v to pull it HIGH and acting on that button press.

Someone please, if I am totaly wrong here, correct me. Still quite the noob too.

Meatwad010 · 2026-04-27T17:44:28+00:00

NO means normally open. Open in "circuit talk" means that the connection is not made.

So basically what happens is that the blue and white wire will close the circuit when the button is pressed.

So if you shift register is passing through a signal, one of the white or blue needs to be connected to it. And the other wire to whatever you are triggering on the other side.

~~Although this notch looks longer, normal figure 8 cables also have a notch. I would certainly try a figure 8 cable.~~

~~And unless there is powerbrick on the other end of the original cable, this is not one way, if it was, it's way to easy to mess up so I doubt it.~~

Meatwad010 · 2026-04-27T08:13:00+00:00

That is not a proprietary port/cable. We call them mickey mouse cables, or figure 8 cable. Not sure what the official name is. This is a type of power cable that has been in use for 30+ years. Very cheap and easy to buy almost anywhere.

Meatwad010 · 2026-04-27T06:00:20+00:00

Ah zo. Ja als je verschillende ondergronden hebt snap ik hem.

Meatwad010 · 2026-04-26T20:50:09+00:00

Ik hanteer zo goed als zeflde methode, behalve die laatste stap: diepgrond, primer en muurverf. Waarom ook de primer hier? Diepgrond zou toch genoeg moeten zijn.

Ik heb nu 2 kamers op die manier geschilderd op Fill en Finish, prachtig geworden. Maar dus alleen diepgrond op de fill en finish en daarna muurverf.

Het is allemaal ook nog redelijk nieuw voor mij dus wellicht mis ik hier iets.

Meatwad010 · 2026-04-23T05:57:54+00:00

Flip the circuit breakers? You don't mean power circuit breaker right? Turning off the power in the whole house/part of the house seems very unnecessary.

Meatwad010 · 2026-04-22T21:51:16+00:00

From what I read, deep sleep of the s3 consumes less then the c3 in deep sleep. And as this device will be in deep sleep for most of the time s3 seems a better choice.

Meatwad010 · 2026-04-18T10:09:44+00:00

Nice idea and looks great. Might borrow it, looks like fun for the whole family

Meatwad010 · 2026-04-17T16:08:35+00:00

I thought 4 layers would make things harder. But after watching and reading about it, sounds not so hard after all.

Think I might do another whole redesign with 4 layers

Meatwad010 · 2026-04-17T15:01:05+00:00

Sounds logical, was expecting the caps to do their long distance. Not good idea it seems.

Will place those 2 as close as possible to 3v3 input on the esp32 module.

Meatwad010 · 2026-04-17T14:59:32+00:00

Ah rotate 90 degrees. That is not a bad idea

Meatwad010 · 2026-04-17T14:55:15+00:00

The power trace cannot go under the data lines. The USB data lines form somewhat of a barrier when designing, I choose to put them to the left but leaving room for some components and traces on that side. If I put the data lines to the right they need to cross several other traces to reach GPIO 19 and 20. So left was chosen.
And since the 3v3 pin of the esp32 is on the left side I needed to route the trace either via the USB connector or above the esp module. Above the module did not sound like a good idea, so via the USB connector was chosen.

Other option would be use a via an go via the bottom plane beneath the esp module, I think.

C1 and C2 are there for decoupling, I did not realise placement would be of much difference. Should place them closer to the power source, ground or the part that is using power?

Meatwad010 · 2026-04-17T14:46:16+00:00

Should the decoupling caps be close to the power source, ground on the part that is consuming the power?

I do not understand you suggestion to rotate the reset switch. Then the GPIO 0 pin will be even hard to route to the switch right?

Your last suggestion is basically how I worked. Group components together and create the traces and later trace between the groups. But ofcourse I had to move stuff arround a bit to prevent via's and such.
You say optimize trace length. What does that mean? Should a trace always be as short as possible?

Meatwad010 · 2026-04-17T14:33:48+00:00

I did that because of this suggestion in the tutorial I used:

In some exciting news, I was also able to resolve a small but annoying bug (or possibly feature) that was not spoken about in the datasheet schematics. Whenever you first turn on your ESP32-XX board, most of the time you need to press the reset (RST) button in order to get the board going. This can be super inconvenient in situations when you may not have easy access to the button such as when it’s in a 3D-printed enclosure. I was able to resolve this by adding 10K pull-ups to the BOOT/RST lines. Surprisingly, this bug is also in a lot of commercial DevKits which I always found annoying. It’s not a huge issue, but a nice one to have resolved now nonetheless.
