As I was getting RSI in my finger, a problem commonly known as computer mouse finger, I thought I would investigate. Specifically when I click with my index finger, I feel a pins and needles feeling.
The more I click with my finger, the more it hurts and the worse the effect is.
So I decided to do something about it.
I developed a device which I call Click RSI which is a device that turns a metal surface into a left mouse button. Because the Click RSI uses capacitive touch, you no longer need to click anything. A simple tap on the metal item will click the mouse for you.
Here's a picture of the "Click RSI" prototype..
You can buy one or make your own.

I had a problem with my left click finger.
It started getting pins and needles and feeling numbe when clicking my mouse at work. That was bad, so I thought about assigning a key to left click.
Then I remembered I had a Trinket M0 - so I made a capacitive touch left mouse button.
You can make your own or buy one pre made from me, but it consists of.
1. USB Cable
2. Trinket M0
3. Crocodile clip - to attach D3 to any metal object which can act as a mouse button (touch)
4. This code...

How to set everything up.
a. Connect the trinket to your computer using the usb cable
b. Load the code onto the trinket.
c. Connect crocodile clip to D3 - terminal 3 on trinket
d. Connect other end of crocodile clip to object you want to touch as mouse.
I use a tape measure.

This is the simplest way to backup your pi.

Backing up your raspberry pi is fairly straightforward. Here's my quick and easy guide. Script by Mark at projektor.co.uk
Raspberry pi
USB drive for backup
Assuming you have no other drives connected to your pi.
Insert a USB pen drive into your raspberry pi.
Issue the following command:
wget -c https://raw.githubusercontent.com/markcity/pibackup/a2fd2b9697a61a6e3f8c8b60546ac7a54abe8041/makeimage.sh;bash ./makeimage.sh
When completed you will have an image of your pi on the USB stick.
You can safely remove the USB stick.
Use Win32DiskImager - download link https://sourceforge.net/projects/win32diskimager/
#create a variable today using the current date in the format Year-Month-Date
today=$(date +"%Y-%m-%d")
#set up a folder to map to the usb drive
sudo mkdir /media/usb
#make the new folder owned / writeable by the user
sudo chown -R pi:pi /media/usb
#map / mount the usb stick at the folder /media/usb
sudo mount /dev/sda1 /media/usb -o uid=pi,gid=pi
#just in case, give the raspberry pi ability to write to NTFS file format
sudo apt-get install ntfs-3g
#use dd command to backup the 'mmc' - SD card to a file
sudo dd if=/dev/mmcblk0 of=/media/usb/pi_img_${today}.img bs=1M
#unmount the USB card so it can be
sudo umount /dev/sda1I recently tried to update the wordpress installation on useful.website and got the following message.
I use a dvd-rw to store the latest image of windows 10.
In the recent update the size of the iso file was too big to fit on a single layer disk and the recommendation was to write to dual layer.
However dual layer dvd-rw doesn't exist and I don't want to create more waste.
So here's the method I used ...
Rufus download method...
https://pureinfotech.com/download-older-iso-windows-10/
I used the option to download via browser.
Direct download link analysis:
July 2020 build (4.9GB - may just fit!)
October 2020 build windows 10 International English
Verdict: too large for DVD-R/W
It would be great to say "one simple pill" would be a cure. It is not. However there is a significant factor. Here I present recent information I received that is backed up by observation of data and a way to eliminate one factor.
Here's the TLDR ( too long didn't read ) summary.
All detail is provided below.
1. The information
Firstly the information relating specifically to this disease was published in nature website recently. It relates to the Autumn 2020 surge and a main contributing factor.
2. The observation
There is a direct correlation between a drop in amount of UVB exposure and this happens when the sun is low in the sky.
3. The conclusion
When the UVB exposure drops below a certain level, we are at a significant increased risk of getting Covid. Why? Because UVB exposure allows our bodies to create vitamin D but only at certain times of the year. Unless you live around the equator.
