On discovering the Fritzing freeware circuit prototyping application on the network at work this week.

I have drafted new versions of my home network sensor circuits using the application and uploaded them to my sensors page.

The three circuits are for a Reed Switch, PIR Module and Pressure Mat connected to a Raspberry Pi computer. For example here is the Reed Switch Schematic and Breadboard Prototype.

The breadboard diagram details the wiring between the Raspberry Pi, Breadboard and Reed Switch.

I have created a FM Music Transmitter using a miniature USB FM Transmitter and a Raspberry Pi.

Some simple bash scripts are written to select a random tract from a playlist and play it through the FM Transmitter. I also output details of the tract to the connected LED Matrix displays.

I have added another page to the Stock Price project detailing a horse race between discs and memory within MySQL.

I used a logging script to capture the resource usage for every second and used a timestamp table to record the progress of the SQL scripts.

The results were loaded in to Excel and a pivot chart was generated.

This week I added the URL of my work from 2013 to the internet archive

I recommend this as often potential employers wish to see a portfolio of prior work.

Given that this work maybe removed from the public internet after the project completes. I believe it wise to have a copy archived on the way back machine so that it will out live the actual website.

Here is the way back machine copy of my prior work

I have detailed my work with a Windows Server 2012 virtual machine on NeCTAR. It has 920GByte of RAM and 64 cores.

MySQL was installed on the system and used to generate results for the Stock Price project.
