Monitoring laser usage

We have had a good few spendy problems with our laser cutter over the past few months and it’s one of our most heavily used tools. We need to build up a bit of a kitty to make sure we can replace laser tubes (like this) and power supplies (like we had to recently) as well as mirrors and other consumables.

Step up Andrew Jacobs who built a PIC based monitoring solution, it monitors a pull up on the laser cutter PCB which pulls 8ve when the laser is firing. Andrews design monitors this and keeps a log in the eprom whilst displaying the session usage and overall usage so that members know how much to put in the pot after using the machine.

Simon Green designed and made the case which looks particularly good :)

The next stage will be to tie the system up to our member RFID cards so we can manage the tabs!
