Miata NA (1991) Valve Gasket Replacement


Fairly straight forward procedure on my 91 Miata.

Couple of my observations

 I did not have to mess with any electrical connections. By removing the two 12mm bolts, one on either side of the spark plug wire bracket, I was able to slide the cover out.

Be careful tightening the 3 inside bolts along the center line. I snapped the center bolt. After removing the valve cover I was able to easily back out the bottom 1/3 of the bolt. Initially I thought I might have to use a bolt extractor. Bolt was available at home depot (flange bolt M6 x 1.0mm x 40mm.

Bought a Sears craftsman "clicker style" in-lb torque wrench (on sale for $50) to eliminate guess work for tightening bolts to 43 - 78 INCH-lbs the second time around. Unfortunately it did not "click" no matter what torque setting. Reading the reviews (after I bought it of course) appears I was not the only one.
Bought gasket from O'Reilly's auto store. Fit fine. Gasket sealant does not come with despite what the salesman told me so another trip back to the store. Only later to realize I already had some.

Telnet into VSTARCAM T6835WIP PnP IP Network Camera


Given Mirai malware was interested in my vulnerability and found the password on a russian web site (thanks google translate).  If I can figure it out then the "bad guys" already have it.  Therefore I feel comfortable sharing so folks can actually do something about it (i.e. change the password)

login: root
password: 2011vsta

on a windows 10 machine, used Putty

Host name: 192.168.0.192
Connection type: Telnet
Port: 23



typing in busbox at the # lists available functions
use chpasswd to change password

# chpasswd (enter chpasswd at #)
root:newpassword (on blank line enter root:'newpassword'

should get response
Password for 'root' changed

hit enter and ignore the message
chpasswd: missing new password

Scorpion Bay Surf Trip - Oct 2016

Preparations
- Read Baja Surf Guide or at least visit http://www.thesurfersguides.com. Lots of good advice.
- I bought a DSURF travel bag. 10' and holds 2 boards.  Bag got trashed by the airline on the return flight so something to consider if thinking about renting a bag.  Do not recommend the bag as need a sturdier canvas outer shell.
- No ATM's in San Juanico.  Several in Loreto

Getting there from Loreto Airport (as of Oct 2016)
-  3:15 minutes via highway 1 south, then west, then north.
-  Google maps/Garmin no good once you are north of  Ciudad Insurgentes.  Looks like it has been several years since last google earth/maps update.
- Watch out for two unmarked speed bumps as you drive through a small town 10 miles north of Ciudad Insurgentes.
- Take Las Barrancas exit (25.9939 N,-112.1162 W) about 55 miles/88km from Ciudad Insurgentes .  Follow signs to San Juanico.  About 45 minutes to town of San Juanico


Driving/Roads
- Roads were in good shape, mostly.  Paved all the way except for spots when when they were not.
- Roads are narrow and drop off with very little shoulder.  If you need to bail right to make room for an on coming truck, careful you don't get a tire over the edge.
-  Take it easy heading south from Loreto as lots of hills and winding roads.  Only policia I saw was 10 minutes south of  the airport.
- You can make good time once you turn west and then north as roads were straight and in good shape, mostly
-  Roads were washed out in several places so road conditions can go from perfect asphalt to 2 foot drop off without warning.

Surf
- mostly surfed 2nd point.  occasional waist high.  a bit crowded as more folks (~10 - 12) waiting at the point than waves in a set.  mostly friendly with better surfers somehow not managing to wait in the line up

Scorpion Bay Hotel
- Good news A/C and Wifi
- Bad news they shut the power off at 11 pm most nights so obviously no A/C or Wifi
- rooms were nice and staff friendly
- Wifi was a shared connection so limited bandwidth.  no streaming.

Remote Desktop Connection Black Screen Raspberry Pi [solved]

Readers Digest version:  Change resolution in the /boot/config,txt file

Long version

Replaced motherboard on my desktop to include installing new graphics drivers.

Tried to RDC into the Pi and got the black screen.  Connection was OK as I could SSH in.

sudo nano /boot/config.txt

had to change both the overscan (top,bottom, left, and right) as well as hdmi_group and _mode.

Porsche Cayman headliner replacement

2008 headliner started sagging last week.  Lots of google searches later here is my story.

I only did the remove/replace headliner and had an upholstery shop replace the liner for $150.  As you need to replace the liner anyway, made sense for me to have someone else mess with preparing the surface (remove old foam), applying the glue, and getting the contours fitted properly.


Looking back, it was not that difficult and I would do it again.

 two helpful you tube videos.

https://youtu.be/iZHIeiUFXJg

https://youtu.be/HZVlMKG3UKo  (before you complain about the video quality, try taking video yourself while performing this procedure)

Hardest part by far was separating the A and C pillars.  everything else was easy.



 
looking towards the back,

looking down
I started with the C pillar first. I did not remove the whole thing, just unclipped the section closest to the A pillar.  step 1 was removing the trim from around the seat belt feed behind the seat.  there are 4 tabs and 2 slots.  I started with the tab closet to the outside of the car.  insert a plastic trim tool in the gap and rotate.  this technique worked for the 4 tabs.  pried up for the 2 slots in the back. remove one star bolt. i used 7/64 hex.
















 
this was the hardest part.  separating the 3 tabs connecting the A and C pillars.  Although I took out the light, I did not need to as there is enough play in the wire.  circle 4 is the one fastener I did unhook to prove enough play to allow a pillar trim to slide past c pillar trim.  it looked a little tight in the video where they did not remove it.









this is a view of the 3 fasteners on the A pillar trim piece that connects with the C pillar trim piece.  bottom of the picture is also bottom of the trim piece. looking at inside of drivers side piece.









once C pillar trim piece was loose, pulled the A pillar trim away from the car at each slot starting with the one closest to the back of the car.  careful with position 5.  need to pull away from the car but also, once loose pull trim piece towards the back of the car so as not to damage the tab on the end.

 5 slots where the A pillar fasteners line up




drivers side A pillar trim with location of fasteners.  on both sides, the fastener in position 5 stayed on the frame.  used needle nosed pliers to extract and fit back onto trim piece.  nothing broken.

after A pillars, removed sun visors, light, and garage door remote.






for sun visor, remove plastic cover then unscrew.


on the clip. pull down the plastic cover to reveal screw.







for the light, two tabs at the front.  you do not need to disconnect the wires as assembly fits through the opening


tabs for the garage remote are on each side.  no need to remove wires as assembly fits through the opening








removal/replacement.  pushed both the light and garage door opener through the headliner and was able to slide out the passenger side door.
would have been easier with  a helper during replacement.

pip install motioneye

5. Prepare the configuration directory

mkdir -p /etc/motioneye

cp /usr/local/share/motioneye/extra/motioneye.conf.sample /etc/motioneye/motioneye.conf

6. Prepare the media directory:


mkdir -p /var/lib/motioneye

7. Add an init script, configure it to run at startup and start the motionEye server:

cp /usr/local/share/motioneye/extra/motioneye.systemd-unit-local /etc/systemd/system/motioneye.service

systemctl daemon-reload

systemctl enable motioneye

systemctl start motioneye

8. To upgrade to the newest version of motionEye :


pip install motioneye --upgrade

systemctl restart motioneye

9. open motioneye

from web browser enter "http://[your raspberry pi ip address]:8765"

10. add camera

[recommend you test out the connection to your IP camera [i used yawcam and iSpy64] from your laptop/desktop first so you know it is working.  i needed to enter my user name and password in the url only, not the user name and password blocks.  if i just entered in the user name and password blocks I got a "camera not supported error]

camera type = network camera

url = http://[ip camera address]:port/videostream.cgi?user=[username]&pwd=[password]"

'example http://192.168.0.199:81/videostream.cgi?user=USERNAME&pwd=PASSWORD"
