Lets learn something new

 The ESP32 integrates four SPI peripherals. SPI0 and SPI1 are used to access the ESP32’s attached flash memory and thus are currently not open to users to be used . They share one signal bus via an arbiter. SPI2 and SPI3 are general purpose SPI controllers, sometimes referred to as HSPI and VSPI, respectively. They are open for use. SPI2 and SPI3 have independent signal buses with the same respective names. Each bus has three CS lines to drive up to three SPI slaves.  

The post explains 2 simple universal current controller circuits which can be used for safely operating any desired high watt LED. The universal high watt LED current limiter circuit explained here can be integrated with any crude DC supply source for getting an outstanding over current protection for the connected high watt LEDs.  Why Current Limiting is Crucial for LEDs We know that LEDs are highly efficient devices which are able to produce dazzling illuminations at relatively lower consumption, however these devices are highly vulnerable especially to heat and current which are complementary parameters and affect an LED performance. Especially with high watt LEds which tend to generate considerable heat, the above parameters become crucial issues. If an LED is driven with higher current it will tend to get hot beyond tolerance and get destroyed, while conversely if the heat dissipation is not controlled the LED will start drawing more current until it gets destroyed. In this

 This tutorial is about properly setting up WSL2 X11 forwarding on Windows and Linux distro Add the following to your ~/.bashrc :  export DISPLAY=$(awk '/nameserver / {print $2; exit}' /etc/resolv.conf 2>/dev/null):0 export LIBGL_ALWAYS_INDIRECT=1 Enable Public Access on your X11 server for Windows.* Add a separate inbound rule for TCP port 6000 to the windows firewall in order to allow WSL access to the X server, as described by the wsl-windows-toolbar-launcher people. On the Ubuntu Wiki page about WSL you can already find a configuration adapted for WSL2 under Running Graphical Applications . A similar configuration is also suggested by the above mentioned Reddit User, who also contributes another part of the solution: Enable Public Access on the X11 server under Windows.

On Windows 10, it is possible to upgrade the Windows Subsystem for Linux platform to version 2, this included the already installed Distributions, and in this article are the steps required to convert to WSL2. The Windows Subsystem for Linux 2 (WSL2) is an updated version of the implementation that uses a very light virtual machine instead of a direct translation between both operating systems, allowing for noticeable improvements in performance and complete call compatibility support. In this article are the steps to upgrade WSL to WSL2 and convert Linux distros to version 2 on Windows 10.   Download this WSL2 kernel update (required  Install the downloaded file   Open Start. Run PowerShell in Administrative Option  Type the following command to set Windows Subsystem for Linux 2 your default architecture for new distros you’ll install and press Enter : wsl --set-default-version 2    Type the following command to get a list of all the distros installed on your device and press Enter:
