RSI Clicker - click free mouse clicking for RSI Support

 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..

How to prevent RSI in finger with mouse click? [solved]

 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.

Backing up your raspberry pi is fairly straightforward. Here's my quick and easy guide. Script by Mark at projektor.co.uk

Requirements

Raspberry pi

USB drive for backup

Instructions

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.

Want to restore the image?

Use Win32DiskImager - download link https://sourceforge.net/projects/win32diskimager/

 

For reference, the script contains the following lines.

#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/sda1
