 ====== NFC-enabled Tool Lockers ====== ====== NFC-enabled Tool Lockers ======
  
-See also [[https://roundup.ehlab.uk/issues/issue76]]+This project is complete! We have a unit of eight tool lockers in the workshop that stores our Makita cordless tools, and Proxxon rotary tool. 
 + 
 +You can view the contents of the lockers, current status, and who is currently using/last used the tools here: [[https://lockerstatus.ehlab.uk/|lockerstatus.ehlab.uk]] 
 + 
 + 
 +===== Development history ===== 
  
 We have portable tools that require training before use, or which are valuable and at risk of being borrowed or stolen. The proposed solution is to create individual lockable compartments operated by our existing NFC tokens. We have portable tools that require training before use, or which are valuable and at risk of being borrowed or stolen.

 +
 +===== Status ======
 +
 +Wiring the individual locks and sensors is time consuming so only two compartments have been completed. A new PCB has been created to make this easier and we are waiting for it to arrive.
