You need to find the IP address of this device. There are many ways to do that. Once you have it and you are connected on the same network, just the the ip address in the browser.
There is an option after you flash the device that is "visit device". It's the best one to me

Yay! Congrats. I would prefer the power supply. You can overload you usbc port. It's risk, especially when displaying light images, that uses more LEDs.

The green circle is just a female barrel jack adapter, like this one below. It's just to make the connection easy. The power supply is a common one, it's necessary because the led matrix consumes more power than the esp32 can provide.

Sorry, it took more time than expected to get back to you.

```
5V/3A Power Supply (you need one)
+5V ----+----> ESP32 VIN
|
+----> DISPLAY VCC

GND ----+----> ESP32 GND
|
+----> DISPLAY GND
```

Looks great. Let me send you a schema, it's good that you requested this, I realized I don't have a schema for that

Cool. Let me know if you need help

It's not much different from raspberry, except it's in c++ and you have less resources like memory. Creating a new clockface, you will have basic info like date/time and you need to implement the API request to the weather, the wifi connection will be available, just use it.

Hi there! Since it is a connected device, yes it is possible. Consume a weather api isn't that hard as well as implementing a mqtt client to receive notifications. I didn't developed those clockfaces yet. Let me know if can contribute

Billions dumped into this. Billions wasted.

Meanwhile the cost of living crisis makes people's lives a living hell.

This stuff makes me so mad.

Just tested the CrowPi 3—Elecrow’s new Raspberry Pi 5-based STEM kit. It integrates 30+ modules, a touchscreen, and supports microcontrollers like Arduino Nano, micro:bit, and Raspberry Pi Pico. Read my full review and watch the video: https://app.txplo.re/crowpi3

💾 Flashing the Firmware do-it-yourself, full-featured and smart wall clock device - jnthas/clockwise

Hello! Did he follow the instructions here? github.com/jnthas/clock...

What was the error?

Garanti a minha

Oh no. That's it, S3 is not directly supported by the web flashing tool. You need to upload manually, following that guide you sent yesterday

Awesome! Let me know if you succeeded as well haha

Ok, is it possible to detach the ESP32 from the display? if this is a power issue, removing the display should work.

9 months ago 1 0 1 0

Nice! I don't know if this will work, but you can change the firmware they suggested to use by one of the clockwise.

This one is Mario Clock:

Hey. That's a cool project! I have a question before. Do you know if it's based on ESP32?
