Computers!

Doorpi

Presumably handles auth for the door RFID system

• IP: 10.20.30.143

Arcade machine

No network connection. For hardware info, see ArcadeMachine

Embedded systems

Twitter marquee thing

Watches for anything mentioning @hackpgh on twitter and repeats it out. It appears to be a Pro-Lite TruColor, which apparently takes commands over a 9600 baud serial connection.

Resource on making the thing work:

• http://www.instructables.com/id/Communicating-with-a-Pro-Lite-LED-Display-Cable-C/?ALLSTEPS
• http://wls.wwco.com/ledsigns/prolite/ProliteProtocol.html

Network stuff

• Fileshare
• PittMesh node

Web server

The hackpittsburgh.org web server is run off of a VM hosted by Dreamhost.

RFID tool logs

Want to design an RFID log-in system for our tools so we don't need to keep paper logs.

Design goals:

• You turn the power switch on, then beep in
• It checks against your tool training auth and adds use logs to a database with timestamps
• You stay logged in until you power it off
• It automatically tracks tool use time and displays notifications when it needs maintenance
• Powered by the same power as the tool
• Displays useful errors when the network/database is unreachable
• Cheap enough and simple enough to stick on every power tool
• Tool log database run locally
• Connects over wifi
• Display cool stuff on screen
• A face plate that can be laser cut or engraved with cool stuff
• GRAPHS!!!
