[labnetwork] Card Readers for equipment interlocks

[Mike Young]

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)!

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...

Good luck, and contact me offline if you'd like more of the gory details.
