FIXED: Windows update standalone "the update is not applicable"

I was running into an Windows 8.1 error. The error was related to a Windows update that I had previously installed. I proceeded to uninstall the Windows update (that was previously installed) and then tried to redownload the update directly from Microsoft.

When I tried to to install the downloaded update, I received the error message: Windows update standalone "the update is not applicable"

Turns out the problem was due to the wrong architecture. I should have downloaded the 64 bit update instead of the 32 bit update.

Solution: Download the right update for the architecture on your operating system. If you have a 64 bit system, make sure you download the 64 bit updates. If you have a 32 bit system, make sure you download the 32 bit updates.

To check what architecture you have:
Go to control panel
System Type: 64 or 32 will be displayed

PARTIAL FIXED: USB 3.0 External SSD not showing up in Disk Management XHCI

Symptom: Connecting an external USB 3.0 drive, in Windows, does not display in Disk Management. The only thing you see is the device is displayed in connected USB devices.

This happened to me with an Asus Zenbook UX series laptop. Attempts to connect a Samsung T3 drive failed. The drive would not show up in Disk Management, nor in the BIOS. Disabling XHCI in the BIOS allowed the drive to show in Windows 8.1, but this would revert the drive to USB 2.0 which is not what we want.

Re-enabling XHCI in the BIOS allowed for USB 3.0, but again, the Samsung T3 drive was still not displaying.

Solution: The Windows XHCI driver needs to be updated. Go to Device Manager, USB Controllers, then right click the Intel USB 3 XHCI device and select Update Driver Software.

NOTE: Not all External USB 3.0 drives will be compatible with the Windows driver and same goes with the Intel driver. The Samsung T3 works fine with the Windows driver, but another external drive randomly disconnects after copying files.

The driver will update with a Microsoft XHCI driver, and you should be able to see your drive in My Computer as well as Disk Management.

SOLVED: Java 32bit error on 64bit CentOS ::

Attempts to run 32bit Java on a 64bit system, the following errors would display:

/XXXXXXX/runtime/LNX86/bin/java: /lib/ bad ELF interpreter: No such file or directory

Exception in thread "main" java.lang.UnsatisfiedLinkError: /XXXXXXXX/runtime/LNX86/lib/i386/xawt/ cannot open shared object file: No such file or directory

To fix, install the following (tested on CentOS7):

sudo yum install glibc.i686
sudo yum install libXext.i686
sudo yum install  libXrender.i686
sudo yum install  libXtst.i686

Now you should be able to run the Java application.

My laptop BSOD'd a few weeks ago, and I've been limping by in Safe Mode until today. I put my laptop to sleep, and upon wake, the laptop BSOD, and continued to do so every time I booted up. The only message displayed with SYSTEM_SERVICE_EXCEPTION, and viewing the crash dump with BlueScreenView netted no results.

Another symptom: BSOD displayed CRITICAL_SERVICE_FAILED when trying to run a Chkdsk.

2 128GB RAID 0

Problem & Solution
Turns out the problem was a corrupted pagefile.sys file. When the laptop went to sleep, the pagefile.sys became corrupted, and every bootup after that, Windows would try to access the corrupted pagefile.sys and BSOD with SYSTEM_SERVICE_EXCEPTION.

I disabled the pagefile, and the computer now boots up normally. I used the following tutorial on technet:

DIY Reclaimed Wood Mini Pallet Bike Rack

DIY Recycled Mini Pallet Bike Rack
All wood reclaimed from a wood pallet
Measure the distance from the bike top tube and the bike seat. Confirm that you will have enough clearance to the ceiling after hanging the bike to the rack. Then calculate the minimum amount of distance from the wall to the hanging point. Cut wood to size.
Nail the frame. Then attach top and bottom pieces of wood using nails.
Attach to wall using L bracket and 70 pound drywall anchors. Note: my measurements were off and the seat post is just barely hitting the ceiling. 
Use section of pallet with HT stamp to complete the original "pallet look"

Originally built July 24, 2014. Still hanging on strong.

Syma X11 / Hubsan FC & MMW Fast motors Quadcopter Mod

The Syma X11 is one of my favorite quad's to fly. I enjoy flying the geared motor setup for its stability and efficiency. The stock setup gets about 12 minutes of flight on a 380mAh battery. However, the low yaw rates leaves a bit more to be desired. 

After watching Jordy RC on Youtube, his setup provided the best of both worlds. A Hubsan flight controller and upgraded motors from MMW. The Hubsan FC provides better yaw rates, and the option to turn on/off the LEDs during flight. 

Sidenote, if you're using a Deviation w/module transmitter, you'll get Telemetry data for the battery status--mine is set at 3.2V.

Hubsan Transmitter

  1. Disassemble Syma X11
  2. Remove motors and Syma FC
  3. Screw in Hubsan X4 FC. The Hubsan FC will not be a perfect fit, and you'll only be able to get one screw into the board. You can try some foam to reinforce the back of the board if you like.
  4. Transfer the gear pinion from the Syma motors to the MMW motors (or reuse the original Syma X11 motors if you don't want to upgrade to MMW)
  5. Insert motors into the frame
  6. Cut off the MMW connectors. Be sure to leave enough wire length to reach the Hubsan X4 board.
  7. Solder wires to the board (see photo below for wiring. Red and White are Positive +. Black and Blue are Negative -) Motor position are swapped. The wiring does not need to have reverse polarity, only positions swapped.
  8. Transfer LEDs over from the Syma FC to the Hubsan FC
  9. Reassemble the unit
  10. Swap the prop position from left to right
  11. Insert battery and test flight
