About bloody time

17.07.2023 by Andrew

  • Prep: Hot Splash
  • Pre-shave: Phoenix Shaving – Ice CUBE 2.0
  • Razor: Rockwell 6C (4)
  • Blade: Rockwell Razor Blade
  • Brush: Yaqi – Lucky Dice
  • Lather: Ariana & Evans – Vanille de Tabac
  • Post-shave: Ariana & Evans – Vanille de Tabac

Shaving has been very low on the agenda of life for me lately. I’m sure that you have noticed with my lack of Shave of the Day posts here on the blog. I think I may have had one other shave that I have not posted.

I’m actually wondering whether I continue posting these type of posts here. I don’t really post much else *shrug* 🤷

A reluctant shave

31.05.2023 by Andrew

  • Prep: Hot Splash
  • Pre-shave: Phoenix Shaving – Ice CUBE 2.0
  • Razor: Rockwell 6C (4)
  • Blade: Feather Hi Stainless
  • Brush: Yaqi – Lucky Dice
  • Lather: Ariana & Evans – NYC
  • Post-shave: Ariana & Evans – NYC

The desire for a shave has been extremely low the last couple of weeks. The last two shaves have been reluctant shaves after a minimum two weeks of growth, and the dreaded itch starting up.

This morning’s shave was another one of those reluctant shaves.

Install Driver for TP-Link TL-WN823N on Raspberry Pi OS

22.05.2023 by Andrew

I’m looking to create a WiFi hotspot for when we travel. My current idea is to create a WiFi router using a Raspberry Pi as a bridge between our devices (Laptops, Phones, iPads, etc.) and the accomodation’s WiFi (especially where they have captive portals with number of device limitations).

I have a spare Raspberry Pi 2 V1.1 lying around at home, and looking to utilise that going forward. Clearly the RPi 2 does not have onboard WiFi, so a pair of USB dongles is required. However the number of dongles is broad and varied, and driver compatibility can be somewhat limited, finding suitable devices can be a challenge. Hence my search for a suitable dongle.

I have downloaded the latest version of Raspberry Pi OS, and updated with the following:

sudo apt update
sudo apt upgrade 

At the time of writing this article, RPi OS was reporting it was using version 6.1.24-v7+ of the Linux kernel.

The WiFi dongle that I purchased is a TP-Link TL-WN823N wireless USB adapter. I purchased it from Officeworks here in Australia.

The TL-WN823N wireless adapter is based on the RealTek rtl8192eu drivers. These are not present within the Linux kernel at present to my knowledge, and I had to compile them to get the dongle recognised by the operating system.

My first port of call was Google. There are clearly numerous sources, however they all point back to one main source of knowledge, a blog post from Junaid’s Blog.

My first attempt at the following the steps from Junaid’s Blog resulted in an install that was recognised, but I could not get a working connection. Junaid’s Blog points to a rtl8192eu linux driver that allegedly works with the kernel up to version 4.9.35. Clearly I am beyond that running version 6.1.24.

I thought I was shit out of luck at that point. However I did some further digging on a number of forums and found something a little more recent.

My searching directed me towards a Github repository containing a more recent rtl8192eu driver that works with the Linux Kernel up to version 6.4.

Now I followed the following steps to get the driver up and running, and actually working.

sudo apt install linux-headers-generic build-essential dkms git
cd ~
mkdir drivers && cd drivers
git clone https://github.com/clnhub/rtl8192eu-linux.git 
cd rtl8192eu-linux

Inside this folder is the file Makefile, we need to edit the contents of this for Raspberry Pi. We need to find the following line:

CONFIG_PLATFORM_I386_PC = y

and change it to

CONFIG_PLATFORM_I386_PC = n

Then find this line

CONFIG_PLATFORM_ARM_RPI = n

and change it to

CONFIG_PLATFORM_ARM_RPI = y

Now the easiest option from here is to run the included shell script file which does all the hard work for us. Run the following command:

./install-wifi.sh

Let the Raspberry Pi do its thing for a few minutes, and Hey Presto! you now have a working TL-WN823N USB dongle that can connect to any IEEE 802.11b/g/n network.

I am yet to test whether I can run a WiFi hotspot from it, and I am yet to install Pi-Hole as a local Domain Name Server to maintain some control over the kids and their devices, but they are the next steps in putting together a WiFi router for when we are travelling.

What should I write?

16.05.2023 by Andrew

Well I thought about trying to add some content to this blog that is something more than just my Shave of the Day posts. I know I have previously written something about these kind of thoughts in the past.

I’m still not sure that I can commit to writing something regularly to build a following of some sort. But I still have this idea of writing something. The fact that it comes up every now and then means that maybe I should do something about it and at least try, even if it only lasts a few weeks.
