Yeah! Resurected Audio!!!!

It all started at 5:00AM this morning when the mail server at work died.  One of our few single-power supply systems still in use (we have a nice 4 SAS dual-power RAID 10 system to replace it scheduled for deployment Aug 21).   At any rate, the CRAPPY Ablecom SP302-1S power supply gave up (2nd one in 6 months, and it looks like a 3rd one just started to show signs of dying an hour ago) and one of our most critical systems was down!

After getting one of my engineers in route, I knew I’d have some time to look at the ripped up car in my garage.  With time on my hands, I flipped through some axillary tools sets, locating a pair of flat radio removal tools (designed for Alpine head units).  Pondering the possibilities of possibly manufacturing my old keys, I set about cutting up the metal. At least it was something to keep me busy.

It took a few attempts to find the right angles, but I did finally managed to get he head unit (aka Command Unit) removed!!

And, as I suspected, there it was yet ANOTHER fuse.   I’d recalled this morning from projects past, that most of the head units in MBZ had a fuse on the back of them.   And so does this one:

I always have an ample supply of fuses (from careers past).  With hope alive in my heart, and my cell phone by my side waiting to hear from my team, what the prognosis was for our mail server..   I re-attached the mass of plugs (3 analog, one fiber optic CAN, and the antenna);

CODE!  I have the code prompt.  Expensive disaster averted!   Being the fastidious keeper of information that I am, I had the code at hand, and within a few seconds….  was rewarded with the sounds of my favorite local FM station.

TUNZ!
TUNZ!

At least the day did not start out as a TOTAL loss!

My guys called me back shortly after this, and let me know that the server was dead, totally dead, no power.  I instructed them to pull the system from our rack and bring it home for recovery.  I hastely re-assembled my car, got dressed, stopped by Krispy-Kreme to buy them coffee and doughnuts, then rocketed into the office to direct the recovery effort (which is still underway).

At least I could listen to the music for a little while. 🙂

To the Stealer! I need special tools to remove ‘Command Unit’

After a couple hours of net searching, it’s off to the dealer to buy the special tools for removing the stock head unit.   $8.00 for a thin piece of metal.  Porsche is the only manufacture ahead of Mercedes for the requirement of ‘special tools’ to do anything of measure on these cars.     I’ll be sure to post photos of these amazing tools once I get them.  Assuming they have them in stock, the local MBZ dealer in Fife is a real loser.

UPDATED:  As I suspected, the dealer did not have tools in stock.  I’ll be waiting a week for them to arrive.  I don’t know why they don’t have them.  These tools are not very big (small stamped steel keys) they are not very expensive ($9.65 with tax).    They are also used for many model years audio units.   I should have driven to Seattle where they likely gave them away on the counter as nicknacks!

Boooooooo BOSE dies in my car… :(

Arg.  Instead of plowing into the tail-end of the jerk that cut me off yesterday, I am rewarded with the stereo system in my car, dying.

Why and what happened?  I’m still trying to sort that out.  But I do know that whatever DID happen to my car’s audio system, it happened when I had to get deep into the brakes to avoid a rather ‘rude’ driver.  Right then the radio cut.  I thought maybe a bad commercial break or something.   Looked down at the radio a few seconds later and… NOBODY HOME.

I finished my errands yesterday, with only the sound of the 24 valve 4.3L V8 to serenade me.  Now..  there is nothing wrong with the nice sound of a powerful V8 engine (OK.. 285 HP powerful… not too bad for a motor that 262 CID motor that idles like glass at 400 RPM, try that with your S***block Chevy! hahaha) .   At any rate.. BOSE dead.

I parked it in the garage this morning and took the ML to work.  It needed some gas (it ALWAYS needs some gas, powered by the same V8 engine, but pushing AWD and a brick of a body, it’s pretty harsh on the Premium fuel), but I didn’t want to spend the 1 hour commute to work listening to hushed sounds of wind and the expansion joints of the highway.

Upon returning home, I enlisted the assistance of my helper (aka son) and we took the rear end of the car’s interior apart.  The majority of the audio system is located back there so it seemed a good place to start.

Sadly, after checking both fuse blocks, and the fuse on the main audio amp (all good), I’m out of ideas for the quick-fix on the system.  Looks like I’ll have to get the special tools to remove the factory head unit and see if maybe the plug on the back of that came loose during braking.   I hope so…  sad if it happend, happy for me if I can fix it without spending $2500 for all new audio.  These factory systems are all CAN-BUS fiber optic networked.  Can’t just ‘toss in’ a new head unit.

Installing throttle on KZ400

A little more work done on the KZ400 today!

cafe_2209

Yesterday while test fitting parts, I discovered that the powder coated Clubman bars are too thick and interfere with operation of the trottle.

At first, I tried to sand it all off.  I sanded and sanded.  All that provided was a scratched up, equally thick version of what I started with.

Then the lightbulb went off!  I probably still had the paint stripper I used to removed the powder coating on the wheels of my VFR (that project came out looking sweet!!!).  I did not use much of the stripper, and I seldom disposed of chemicals that are pefectly good, so off into the depths of my ‘chemical warehouse’ to locate the stripper.

A few minutes later I wheeled the bike out to the garage door (proper ventelation you know), donned some gloves and started working on the bars.    After the 2nd application it still looked like this!   I have to hand it to the manufacture of these bars, they REALLY used some tough paint!

In the end, I had to use a file to finish off removal of the paint.   BUT, remove it I did, and viola.. I was able to install the throttle and grip (sorry, no photo yet) and it worked like a charm!

A major hurdle out of the way.    Next post..   picking some paint to trail…..   I have….  an  *angle*…   🙂

XBOX 360 – Red Ring of Death (how I fixed my XBOX)

Arg…  just a matter of time before my XBOX died, it would seem.   While I was out having a fun vacation, the XBOX 360 was left on by the kids.  At some point it overheated and started to display the Red Ring of Death:

I tried most of the common external efforts to reset a faulted piece of hardware.  Power cycled, removed power, performed a series of power cycles, left it unplugged for days,  everything I could think of that would help with a typical computer failure.

DID NOT WORK.

Interwebs to the rescue!   After a short Google for articles on the problem, I found a number of YouTube videos showing various ways to fix this annoying problem.  Watching them, they seem to fall into three categories:

Over heat with towels method

Penny method

Heat sink / X-Clamp fixes

Following reviews of various methods above (and I’m sure there are others) I decided I would first try a variation of the ‘Penny method‘ mentioned above.

Others have already documented this process, so I’m not going do it here.  What I will say is that my hybrid penny fix worked, at least for now.   The only change I made to the described Penny Process was that I used 2-penny stacks instead of three.  Another video I watched showed a successful fix with only 2-pennys, and that also allowed easy re-assembly of the C-clamp screws with the shorter penny stack.

There was a trick that I had to watch 4 videos to find.  That is how the proper sequence for removing the outter plastic shell.  I made the mistake of starting on the front (after removing the front panel, which you need to do first, BTW).  After removal of the little grey side panels (snap-crackly-pop, they will come out with careful prying) I tried to go for the ‘easy’ snaps on the front of the enclosure.

It tuns out you should unsnap the REAR of the enclosure first.  The little ‘slots’ across the back are access to a series of snapping clasts across the rear.  Use a small flat-blade screwdriver that will fit IN the slots to push in on them, until you hear a good snap.  Sounds like something breaking, but.. nothing did.  It’s just the way it work.  Once the 8 or so snaps are released, pull the rear apart.  It’s sort of tight, but it does come apart.   Once the rear is seperated, the front is of course very easy to unclasp.  Watch the little DVD/CD drive door button, you’ll need to futz with that a bit.

Once 1/2 of the plastic over is removed, you’ll next need to remove the long silver (6 of those)  T-10 (that’s torx size 10, very small, for those playing at home).   Once those six are out the other side of the cover comes off, and you have something that looks like this:

Now, one last photo.  I can’t say this with any certainty, but it was posted by others that the main issue is those crappy ‘band-aid’ heat transfer spounges on tops of the RAM chips.  There are 4 of those things.  The various penny fixes involved shoving tape wrapped pennies between the metal case and the chips to provide a more conductive material interface.  I used stacks of 2 pennys on each chip, tape wrapped then, reusing the bandades by peeling off the other side of the double-stick ‘band-aids’ fastened the penny stacks to the chips, re-assembled the case and tested.

rrod_2207

Following the ‘post-fix-overheat-to-reset-and-re-melt-heat-transfer-grease’ method, I fired up the box with the fans unplugged until I saw the TWO flashing red ring segments.  This indicates a full-overheating of the chips.   I let the machine cool down, plugged back in the fans, re-installed the fan duct (not seen in any of my photos) and….  VOILA:

XBOX 360 LIVES!
XBOX 360 LIVES!

Sure beats having to sign up for Windoze Live to start an ‘authorized’ repair request.  Microsoft can just ……………….     (you fill in the blank).

So, for litteraly 9 cents (8 pennys and less than 1 cent of electrical tape) I was able to fix the machine.  Of course they could have just put a proper heat sink on those chips for.. hm.. I’m sure less than 8 cents, but no..  just like Microsoft software, they only do an 85% job, and end-user repairs are generally required.

Cafe racing – test fitting some new parts

This week, I have been working with my son on the little Kawi.

While I was vacationing in The Gorge, this past week, a pile of parts arrived for the Kawi.  Along with starting some bodywork on the gas tank, I also performed the first test fitting of a number of new parts:

  • rear turn signals
  • aftermarket rubber grips
  • new stainless headlamp bucket mounting hardware
  • new stainless handlebar mounting hardware
  • bar end mirrors
  • clubman drop-bars (powders coated black, which is turning out to be a problem)

Here are 4 photos of where I left it last night, when it was bedtime for my helper.
