<p> Hope you are doing good. A brief introduction, I am an Electronics engineer </p>
<p>working with UCL (University college London). We have a Clean room facility at London Center for NANO Tech.</p>
<p>Incidentally I was directed to this mailing list by my manager Steve Etienne as we were also exploring option for </p>
<p>card access for clean room equipment.</p>
<p><br>
</p>
<p>We had also developed a custom solution for cleanroom equipment control. The hardware prototypes have been developed by me</p>
<p>and has been under trial for a few months with few simple equipment we have. So far the hardware seems to be working </p>
<p>reasonably well. The system is based on wired ethernet or WiFi (there have been two separate version of the hardware).</p>
<p>The current firmware supports usage logging only as I didn't have the requisite support/expertise for developing the PC side</p>
<p>application/middle ware which would accept UDP/TCP requests from multiple control units and run verification requests </p>
<p>with the data base and send back confirmation UDP/TCP packets to the hardware units to unlock equipment.</p>
<p><br>
</p>
<p><span style="font-size:12pt">Here is a youtube link for the system demo: <a href="https://www.youtube.com/watch?v=S9hz3KTrfno&t=30s" class="OWAAutoLink" id="LPlnk152770" previewremoved="true">https://www.youtube.com/watch?v=S9hz3KTrfno&t=30s</a></span></p>

<br>
</div>
If this seems interesting we could discuss possibility of developing the system further and share designs for mutual benefit.
<p></p>
<p><br>
</p>
<p>Also, I am attaching the system overview block diagram for the same. <span style="font-size:12pt"> </span><br>

<span lang="EN-US" style="color:windowtext">I enjoyed reading Mike Young’s response, since we’re also working on improved interlocks using the Raspberry Pi. We have a working prototype (read: kludge) for a single tool. The eventual goal will be to polish it
to product level quality. What’s nice about the Raspberry Pi is that it has the potential to enable us to collect data from sensors, or create a small embedded systems controller for tools. While prototyping, I’ve successfully programmed a Raspberry Pi to
read an ID number from my government badge. I’d be interested in continuing a conversation about this off-list if anyone is interested in collaborating on Raspberry Pi interlocks.</span></p>

<p><span lang="EN-US">Hi Tom. We use Coral, along with a mix of internet-based interlocks. We also use RFID cleanroom badges. I have made a first-cut implementation of this for one of our resist spinners, using a Raspberry Pi and an RFID reader. It's a bit
of a kludge, I think I can do better, but it is functional. I'd extend the implementation to other tools also, if the darn readers weren't so expensive (~$100 each)!</span><span lang="EN-US" style="font-size:12.0pt"></span></p>
<p><span lang="EN-US">What I have not addressed, is how to do this for equipment which collects run data at disable. I suppose if coral could download the run data from the tool at disable, via SECS or some other interface... That's how the Big Boys do it...</span></p>
