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.
Laptop:
i7
8GB RAM
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 |
 |
| Complete |
 |
| 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.
Materials:
Hubsan Transmitter
Steps:
- Disassemble Syma X11
- Remove motors and Syma FC
- 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.
- 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)
- Insert motors into the frame
- Cut off the MMW connectors. Be sure to leave enough wire length to reach the Hubsan X4 board.
- 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.
- Transfer LEDs over from the Syma FC to the Hubsan FC
- Reassemble the unit
- Swap the prop position from left to right
- Insert battery and test flight
