<p>A stay-on-top (borderless window) countdown timer, with a percentage-based color progress bar as well as sizeable font ... as well as audio file and voice alarms.</p>

<pre><code class="language-powershell">function Start-BootsTimer {

#.Syntax

# Creates a stay-on-top countdown timer

#.Description

# A WPF borderless count-down timer, with audio/voice alarms and visual countdown + colored progress indication

#.Parameter EndMessage

# The message to be spoken by a voice when the time is up...

#.Parameter StartMessage

# A message to be spoken at start up (just to let you know, audibly, what's up).

#.Parameter Minutes

# Some minutes to add to the timer

#.Parameter Seconds

# Some seconds to add to the timer

#.Parameter Hours

# Some hours to add to the timer

#.Parameter SoundFile

# A .wav file to play as the alarm

#.Parameter FontSize

# The size of the timer text

#.Parameter SingleAlarm

# Only sound the alarm once

#.Example

# Start-BootsTimer 180 "The three minute egg is ready!"

# Starts a three minute timer with the specified voice alert at the end

#.Example

# Start-BootsTimer -End "The three minute egg is ready!" -Minute 3

# Starts a three minute timer with the specified voice alert at the end

#.Example

# Start-BootsTimer "Your turn is over!" -Minutes 10 -Single -FontSize 18

# Starts a 10 minute timer that only plays the alert once at the end, and has a small font, which would fit over the task bar or a window title bar...

Remove-BootsWindow $this

} -Async -Popup -Passthru -Background Transparent -ShowInTaskbar $False -Tag $TimerStuff

## Now we need to call that scriptblock on a timer. That's easy, but it

## must be done on the window's thread, so we use Invoke-BootsWindow.

## Notice the first argument is the window we want to run the script in

Invoke-BootsWindow $BootsTimer {

## We'll create a timer

$BootsTimer.Tag["Timer"] = new-object System.Windows.Threading.DispatcherTimer

$BootsTimer.Tag["Timer"].Interval = [TimeSpan]"0:0:0.05"

## And will invoke the $updateBlock

write-host $($_.Exception.StackTrace | Out-String) -fore Red

}

$remain, $BootsTimer.Content.Text = & $BootsTimer.Tag["NowFunction"]

$BootsTimer.Content.Foreground.GradientStops[1].Offset = [Math]::Max(0.0, $remain - 0.05)

## When we get to the end ... make a few changes

if($remain -le 0) {

## The first time we hit the end, we want to add a mouse click handler...

if($this.Interval.Seconds -eq 0) {

## Which will now only fire every few seconds

## So it's easier to close the window ;)

$this.Interval = [TimeSpan]"0:0:2"

## If you click on the finished window, it just goes away

$BootsTimer.Add_MouseDown( { $BootsTimer.Close() } )

## But if they chose -SingleAlarm, they don't neeto bother

if($BootsTimer.Tag["SingleAlarm"]) { $BootsTimer.Close() }

}

& $BootsTimer.Tag["AlarmFunction"]

}

} )

## Now start the timer running

$BootsTimer.Tag["Timer"].Start()
