Lately I've been working on various PCB projects and I'd like to introduce a few of them here.

i2c_slider_75

With this PCB I want to reduce the wiring effort of WinDIY somewhat. The final electronics structure (from WinDIY) consisted of a main board which was connected to the sensors and actuators via individual cables. Among other things, also with the 75mm long linear potentiometer. This meant that a lot of cables had to be connected to the main board.

In order to reduce this effort somewhat, I want to connect the individual sensors and actuators via the i2C bus.

For a first test I developed the circuit board below. The following components are installed on it.

ADS1115 4x ADC
MCP9808 temperature sensor
34 WS2812 2020 LEDs

The 34 LEDs can be used, for example, to display the current position of the potentiometer. Of course, this is not necessary for the actual task.

That's why I separated the strips on which the LEDs are soldered from the main part of the board with a cutout. They are only connected to the main part of the board via narrow bars. If desired, you can easily separate the strips and only use the middle part of the board.

This was my first time ordering boards from PCBWay.com I also used cutouts. As you can see in the photos, this worked really well. 🙂

mini floor lamp PCB

The circuit board shown here will be the heart of a small mini floor lamp that I'm currently working on. The following components are installed on the PCB.

ESP32 as processor
a 3W RGBW LED
BME280 temperature, humidity and air pressure sensor
MPR121 sensor for evaluating capacitive electrodes
LM2596 StepDown converter
TSL2591 Brightness sensor
VL53L0X laser distance sensor
APDS9960 gesture sensor
MCP9808 temperature sensor
WS2812 RGB LEDs on the bottom

The circuit board should later be inserted into the lampshade of the mini floor lamp. If possible, I want to use ESPEasy as firmware.

This board was also made by PCBWay.com manufactured.

nanoPxl V1.3

This board is actually just a further development of the nanoPxl V1.1 board. (More on this here: https://nerdiy.de/howto-elektronik-nanopxl-v1-1-smd-komponenten-verloeten/)

Version 1.3 has the same functions as version 1.1 but is only 17x17mm in size. Version 1.1, on the other hand, was still 20x25mm in size.

Since the board is so small and I needed a lot of them, I included the board PCBWay.com have it manufactured as a panel. This makes assembly later much easier. 🙂

hubCtrlr

With the help of this board I want to reduce and simplify the WinDIY pitch actuator. To do this, I want to move all of the electronics that are necessary to adjust the wing angle of attack into the WinDIY hub.

The following components are installed on the circuit board.
