At some point, I want to wall mount a tablet to provide access to Home Assistant.  Here is some information on wall mounting tablets.

Here is one just about the dashboard for fun

I'm *finally* happy with my HA dashboard!

The easiest way to do this is open up a Cygwin terminal (as an administrator) and type the command:

chere -i -t mintty -s bash

If the icon doesn't show, you can use the following (Windows 10) from within a cygwin window:

regtool -w -s set /HKCU/Software/Classes/Drive/Shell/cygwin64_bash/Icon 'C:\cygwin64\Cygwin-Terminal.ico'
regtool -w -s set /HKCU/Software/Classes/Drive/Background/Shell/cygwin64_bash/Icon 'C:\cygwin64\Cygwin-Terminal.ico'
regtool -w -s set /HKCU/Software/Classes/Directory/Shell/cygwin64_bash/Icon 'C:\cygwin64\Cygwin-Terminal.ico'
regtool -w -s set /HKCU/Software/Classes/Directory/Background/Shell/cygwin64_bash/Icon 'C:\cygwin64\Cygwin-Terminal.ico'

And to remove the icon:

regtool -w unset /HKCU/Software/Classes/Directory/Shell/cygwin64_bash/Icon
regtool -w unset /HKCU/Software/Classes/Directory/Background/Shell/cygwin64_bash/Icon
regtool -w unset /HKCU/Software/Classes/Drive/Shell/cygwin64_bash/Icon
regtool -w unset /HKCU/Software/Classes/Drive/Background/Shell/cygwin64_bash/Icon

If you don't have admin privileges, you can do the following:

Go to your "Send To" folder

C:\Users\<your_user_name>\AppData\Roaming\Microsoft\Windows\SendTo

Create a shortcut "Bash Here" with this target:

C:\cygwin\bin\mintty.exe -i /Cygwin-Terminal.ico C:\cygwin\bin\bash.exe -l -c "cd \"$0\" ; exec bash"

Suddenly all my OpenVPN connections stopped working.  Turns out that the signing certificate expired (took some doing to figure this out).  Here are some links dealing with OpenVPN certificates (and certificates in general)

For PEM, use the following:

openssl x509 -text -in cert.pem

For PKCS#12, use this:

openssl pkcs12 -info -in cert.pfx

To dump a CSR (Certificate Signing Request), use this:

openssl req -text -in request.csr

To dump/check a private key:

openssl rsa -text -noout -in key.pem

I added a backup camera to the truck and to do so, I needed to hook into the reverse switch to make it automatically switch to the camera when put in reverse.  Here are a couple links to wiring diagrams that helped out.
