Plex Media Server – 404 Not Found Issue [RESOLVED]

If you have recently installed a new Plex Media Server and when you load the manage URL you see a big 404 Not Found.  Fear not, this is a simple fix thanks to this forum entry.

Plex Media Server is dependent on rsync but is not installed automatically like it should be. Run:

sudo apt-get install rsync
service plexmediaserver stop
service plexmediaserver start

Then try again!

iShutter: Two Arduino’s Controlling A Video Projector

I finally completed my first “major” Arduino project which I’m dubbing iShutter.  Here’s the scenario:

Willow Creek South Barrington - Summit Day 2 Rehearsal
Willow Creek Community Church

The problem is that at Willow Creek Community Church, a large church with a theater-like stage, often uses a center rear-projection screen for graphical elements during the services. However, this screen is on a motorized batten so that during portions of the service where the screen is not needed, it is flown/raised out of sight, and lowered back in when needed.

However, the projectors sit on the ground at the rear of the stage.  The problem here is that when the screen is raised, if the projectors are not disabled/shuttered, the projection image will be projecting into everyone’s eyes…a quite undesirable scenario.  This shuttering of the projectors has been done manually up till now, but alas, Arduino to the rescue.

iShutter - Transmitter and Receiver Modules (Open large to see descriptions of each elements)
iShutter - TX & RX Modules

Introducing iShutter.  This consists of 2 Arduino Unoscommunicating to each other using the XBee chip.  In a nutshell, the transmit module attaches to the side of the projection screen and uses the PING Ultrasonic sensor aimed towards the ground to detect when the screen is at it’s lower limit.  Once this threshold has been passed, the transmit module then tells the receiver module to communicate via RS232 to the projector whether to open or close it’s shutter.  A button on the transmit box allows users to set the threshold limit.

So, screen lowers in, projector turns on. Screen raises out, projector turns off.

Features:

  • Wireless Transmission between two Arduino Uno control boards
  • 9v Powered Screen/Transmit Module
  • Audio Module to confirm threshold set (plays C chord on Transmit module, followed by a D chord on the receiver module to confirm communication)
  • LED Status Indicator (On TX and RX): Blue (Shutter Closed), Green (Shutter Open), Red (Threshold Not Set)
  • RS232 to Projector – Projector Specific RS232 code to talk directly to device
  • Relay Output of Status – Via Cat5, cabling travels 300ft form receiver module to Video Director to indicate tally of whether projector shutter is open/closed

Learnings:

  • To help increase battery life on the transmitter module, I added the sleepPin logic to put the XBee to sleep when not in use, and only fire it up when a transmission is needed to be sent.
  • Had to dumb down the sensitivity of the PING ultrasonic sensor as it is extremely sensitive!
  • Needed to get a converter chip for RS232 to transmit the proper RS232 voltage so that the projector would see correct RS232!
  • Aluminum enclosures, while sexy looking, seriously decreases the wireless transmission distance! Sad – had to leave the covers off of the enclosures so that the wireless transmission would be solid.

Lakewood Condominiums Association Rules And Regulations, Schaumburg, IL

Lakewood Condominiums in Schaumburg, IL refuses to digitize their Rules and Regulations documentation that they require all of their residents to follow, even going as far as to charge people for the paper copy.  How about this…here’s the digitally scanned copy for those looking.  Enjoy.

Destination Indianapolis: For Real This Time!

As many of you who have followed Jamie and I know, we have never felt settled in our current home and ever since we have been married we have been waiting to move on to a place that we can call home. Throughout the past several years, we’ve looked several times at the housing market to see if we could practically sell our house and not take a significant hit. Every time we have become more and more discouraged. We’ve put great effort into paying down mortgages, saving, being patient, and keeping an eye to the future. We have always seen Indianapolis as an end destination as that is where Jamie’s family is all located…though we have flirted with other stops along the way…but ultimately been sitting in Schaumburg anxiously awaiting. Well, the next step in the plan is in action!
