Computers!

Tomato

Router

Currently disconnected and sitting on top of the electronics shelf. It's a WRT-54G running Tomato, which is fine but massively outdated by now.

It *was* connected up to the marquee sign watching for twitter mentions of us, but that's disconnected for now. You *could* connect it up behind the new router (after turning off the wifi and getting the right network settings put together) and have it keep doing that, but I'd heavily recommend just putting the twitter-watching script on a different machine (diskpi perhaps?) and just ditching this one. We're short of electrical sockets for random doodads and computers.

Gargoyle

New router, as of Sep 2016. A Netgear WNR2000 running OpenWRT 15.whatever, sitting on top of the electronics shelf next to the ceiling cat. Username and password to log in are on a post-it note stuck to it.

Need to go through its DHCP leases and set up static IP's for the various things we want to have static IP's.

  • IP: 10.20.30.1

Diskpi

Fileshare Printer machine. A raspberry pi 2, velcro'ed to the left bookshelf. Owned by John Lewis.

Printers is shared over ipp and Samba. If you are joined to HackPGH you can find the printer and searching for a network printer. HP LaserJet P2035 is has toner right now. You have to use the drivers on your own system. It is confirmed to work with Windows Linux and Mac. If you have an issue with the printer, send a message to the mailing list. Please don't leave printers unpluged.

There is a 250GB Disk with 100GB dedicated for sharing files over smb and sftp. You can connect to to sftp by using the "anonymous" account with no password to connect. You can connect via Samba by browsing to the share through your Operating System's Network Sharing Center. If there is an issue with seeing the files please make sure the hard drive is seated properly and all of the cables are plugged in. Restarting the storage or the Server may be necessary to make read write errors go away.

Diskpi has installers for the Windows and OS X versions of Hedgewars 0.9.22 and The Battle for Wesnoth 1.12. Linux users can check their repositories.

  • IP: 10.20.30.10, 10.20.30.113

Prespi

Displays cool stuff on the monitor above the Raspberry Pi station whenever the door is opened. Raspberry pi 2, with no case velcro'ed to bookshelf. Owned by John Lewis. It it is running osmc with kodi as the display and VideoScreensaver running the slideshow http://kodi.wiki/view/Add-on:VideoScreensaver.

  • IP: 10.20.30.104

There is a web site at port 80.

The computer is configured to put the TV to sleep after two hours of inactivity. Research is being done to have a switch or a web event cause activity. Until then just turn the TV on before events.

Doorpi

Presumably handles auth for the door RFID system

  • IP: 10.20.30.143

Hangtop

A mini desktop machine intended for Google Hangouts. Sitting on top of the sound amp next to the front whiteboard. Set up to be a VNC server hooked up to the projector. For credentials, ask Simon or John.

  • CPU: Intel Core 2 Duo, 2.3 GHz
  • RAM: 2 GB
  • Graphics: Integrated
  • Disk: 40 GB SSD
  • OS: Debian 8
  • IP: 10.20.30.147

To play music at the shop or watch videos/presentations on projector:

  • Download Ultra Vnc Viewer http://www.uvnc.com/downloads.html on Windows or install Remmina Remote Desktop from your software repository on Linux.
  • Put in the hostame or the IP address above if you are running Windows.
  • Put in username and password (the one you received during training by John Lewis or Simon Heath)
  • Connect
  • You are now in control of the computer which is on the shelf near the whiteboard (the one on top of the audio amplifier). This computer runs Linux. Its already connected to the projector and the amplifier and the microphone is connected also.
  • Run various Linux applications and you will be able to see them on the projector and hear them on the HackPGH speakers, such as Youtube, Audacity, VLC Media player, and etc.
  • Its that Simple!
  • No long annoying cables to run from your computer to the projector and audio amp.

If it won't turn on, check to see if it is plugged in.

Tips

  • To get the system to echo back what you say in the mic through the speakers, go to PulseAudio Volume Control. Go to input devices and set mic to 99%.
  • To record with audacity, set mic to 48% to suppress buzzy background sound.

Arcade machine

No network connection. For hardware info, see ArcadeMachine

Embedded systems

Christmas light display on window

Controlled by an arduino. See https://github.com/genekern/DetroitMaikerFaireBox or https://github.com/GregoryLand/G35FrameBuffer for source; the pins might have to be altered a little dependin gon how the thing is wired.

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.
