Can Powershell put counter values in the system tray? - windows

Question

I am trying to monitor my Wifi adapter's throughput numerically on the system tray; like so.
I figured out the static Powershell query
((Get-Counter '\\mullick1\network interface(intel[r] centrino[r] advanced-n 6205)\bytes total/sec').countersamples).cookedvalue*8/102400000*100
But how can I get the continuous feed and how do I put it on the system tray ?
I found an alternate solution in the Diskled software. But it doesn't show the actual value.

This is the script to render(update) a text at a notify icon.
Customize the "Get-NotifyIconText" function as you like.
#Requires -Version 3.0
function Get-NotifyIconText {
[DateTime]::Now.Second.ToString()
# ((Get-Counter '\\mypc\network interface(Intel[R] 82579V Gigabit Network Connection)\bytes total/sec').countersamples).cookedvalue*8/102400000*100
}
