<#
.SYNOPSIS
High Performance Powershell Module Installation
.DESCRIPTION
This is a proof of concept for using the Powershell Gallery OData API and HTTPClient to parallel install packages
It is also a demonstration of using async tasks in powershell appropriately. Who says powershell can't be fast?
This drastically reduces the bandwidth/load against Powershell Gallery by only requesting the required data
It also handles dependencies (via Nuget), checks for existing packages, and caches already downloaded packages

        .DESCRIPTION
        This command blocks, reading a file until a line appears that matches a pattern. If the 
        line matches the pattern, the entire line is written to the output stream.

Relay circuit design & spec for domestic electrical heating 
============================================ 

I have multiple Tado Smart Thermostats, model RU01, and multiple rooms with electrical underfloor heating. I require a power-switching circuit for the heating.

The heating in the largest room has a resistance of ~14 ohms and should run at 230VAC (I'm in the UK). All other rooms have higher resistance. This is a purely resistive load. 

Tado do not provide great datasheets, but they have three pins for simple NO/NC/COM. I found a downloadable user guide at http://www.free-instruction-manuals.com/pdf/pa_1184164.pdf which states:
    - Relay: max. 240V AC 6(4)A / max. 36V DC 6(4)A

    When you are roughing out a C# type in powershell, and you don't want to fire up
    Visual Studio, it can get tiresome having to constantly reload your script editor.

    This increments the class name each time you compile it.
