NERP - Not Exclusively Raspberry Pi Message Board › NERP tonight! It's simple: It's not really simple.
NERP is not exclusively raspberry pi, the small computer interest group at
Pumping Station:One in Chicago.
This past January Raspberry Pi sales reached 1-million units. That's a lot of single-board computers. I'm guessing that a significant number of them have never been booted. Why? It's simple: It's not really simple. Getting a new Pi up and running isn't always plug-and-play. From many peoples' perspective there's a lot of overhead between receiving the Pi and playing with media apps or programming. Part of the fun of doing a new setup is that it seldom goes right the first time. Finding and fixing problems/mistakes is as much a part of the process as anything else, and it's where you really get to know what you're working with. At NERP tonight, we'll step back from the assumption that everyone in the room has a functional Raspberry Pi. We'll start from zero and and get a fresh system up and running and have a look at what kind of stuff the Pi can do out of the box.
Access control on a machine tool
Several of the large tools in the shop will get a Raspberry Pi based experimental retrofit of their power circuits. To limit operation of the tools to persons who have been certified to use them, we will add NFC/RFID readers to check a user's RFID/NFC fob or card against a database. If the user comes up clear, the Pi will turn on power to the tool. As of now our new metal lathe is more or less ready to receive the control circuit input from the Pi. The project is still in the concept/planning stage and suggestions on different Pi-based approaches are very welcome.
