        I have updated FEDEVEL’s Directory structure by the following way:

        <ul class="content-list">
            <li class="content-list-item"><span class="content-text">Design Files directory – the files used during development. Regularly backed up and versioned.</span></li>
            <li class="content-list-item"><span class="content-text">Released Files directory – the files which were sent to production. Regularly backed up and versioned.</span></li>
            <li class="content-list-item"><span class="content-text">Work directory – the files which can be downloaded from Internet.</span></li>
        </ul>

        <h2 class="blog-content-heading">For standard projects I use Google Drive. How?</h2>
        I have a server, where I run <a href="https://www.google.com/intl/en_US/drive/download/">Google Drive application</a>. This application does <b>backup and versioning</b> of everything located in Google Drive Directory – <b>automatically</b>. In this special Google Drive directory, I created Design Files directory and Released Files directory. These two directories are Shared & Mapped on company network (under R: and S: letter) and accessible from all FEDEVEL’s computers.<br><br>

        So, the design and released files are automatically backed up, versioned, accessible and located out of company in case of unpredicted disaster (lighting, flood, …). It’s simple to set up, very useful, requires no maintenance and costs only $3 a month. For special clients who requires confidentiality, I use my own backup server.<br><br>

        <i>Note: Each directory contains Read Me.txt file to explain what kind of files should be located there. It helps to keep your standards on same level for each project / person and make your documentation clear.</i><br><br>

        If you like the structure, you can use it for your new project too. Simply copy the directory from this template and rename it.<br><br>

HW Development Directory Structure and File Backup Setup

<div class="entry-content">

        I highly recommend these tests. If there are any weak points in your design, these tests will find them. No errors yesterday. <br><br>

        I use the chamber to run boards in different temperatures (usually -40°C to +85°C). Most common errors are caused by failing crystals (crystal doesn’t start oscillating and the board doesn’t boot up in low temperatures) , failing memories (if there is a problem in your design, memory may start failing at certain temperature) or board is crashing in too high temperatures (some components go too hot and fail).
    </div>

    <div class="blog-content-text">
        <b>Tip: Always run the setup at your bench for couple of days first – just be sure there are no errors. Otherwise, you will not be sure if possible errors were caused by temperature change or your setup.</b><br><br>

        <i><u>About the picture:</u> Board is not visible (hidden in the right side of the chamber). You can see <a href="http://www.passmark.com/products/usb2loopback.htm">Passmark USB loopbacks</a> going out of the hole from the chamber + SSD hard drives + ATX power supply. VGA output from board is connected to the monitor. My laptop on the right – connected to the board via Ethernet.</i>
