The dishwasher is still under warranty but LG customer service are more interested in annoying their customers than helping them. They refused to honour the warranty so I guess it’s up to me to fix it myself.

After checking for obvious things like blocked nozzles on the spray arms or clogged filters, I tried an experiment. I pointed the top and bottom spray-arms straight ahead then ran the dishwasher. The bottom arm was still in exactly the same position after the wash. So no water was getting to the bottom sprayer which suggests a problem with the diverter valve which distributes water between the top and bottom sprayers. The cause could have been lots of things including:

• Blocked jets or pipes
• Wiring problem
• Faulty sensor
• Controller board or software problem
• Mechanical jam of the valve

Next I put an AC voltmeter across the valve motor. This proved that power was going to it at the right times, it just wasn’t turning. So it must be either a mechanical jam or a faulty motor. I disassembled the valve itself and it didn’t seem jammed so I guess it’s the motor.

A replacement motor costs $54 from LG but Statewide Appliances in Adelaide have exactly the same part for $18. You have to be a bit of a contortionist to reach under the dishwasher and get to the motor but after a bit of swearing, scrapes and bruises I got it out and swapped in the new one.

Three days and about 7 loads of dishes later and it’s running fine. I call that fixed.

There must be some bad technology vibes about this year, or maybe it’s some kind of karmic message that I own too much stuff.

First install the tool:

sudo apt-get install subtitleripper

Then use ffmpeg to see how long the first part of the movie is:

ffmpeg -i movie.part1.avi

Look for the line which tells you the length of the movie. It will be something like 00:45:15.56. Whip out your calculator and work out the length in seconds, in this case it will be 2715 seconds.

Finally use srttool to displace the timing in the second subtitle file and append it to the first one:

srttool -d 2715 < movie.part2.srt >> movie.part1.srt

movie.part1.srt will now contain complete subtitles for your movie.

So I climbed in through the back seat and attempted to open it from the inside. Trying to force the catch with a screwdriver didn’t work so before I broke anything by trying too hard, I yanked off the inside trim and had a look. Turns out there is a short cable running from the door handle to the lock and this had broken.

Now that the trim was off, I could yank the lock mechanism by hand and get the tailgate open.

Of course this had to happen on a long weekend so I had to wait until Tuesday before I could call Subaru and try to get a replacement cable.

How much would you expect to pay for a very ordinary-looking cable about 20cm long? $5? Maybe even $15? – Not Subaru. They charge $90 and it’ll take a month to get it!

“Sod that” I thought (or words to that effect). I went to a bicycle shop and bought a gear cable and sheath for $4. I got a gear cable rather than a brake cable because they are thinner and less likely to stretch. Now to fit it.

The first problem was that the gear cable was much larger – both longer and thicker than the Subaru cable and did not have the same kind of connector at the end, cutting it is no problem but I can’t fit it inside the original sheath because it’s too fat. I had a go at cutting the bicycle cable’s sheath down to size but I had some difficulty fabricating an end cap that would fit the car – so in the end I just unwound a few strands from the cable so it was thinner and could fit inside the original sheath.


The next problem was the custom Subaru hook-things on the end of the cable. I just ripped them out and searched my parts box. I found a couple of small bolts with spring washers, the washers have teeth which should grip the cable pretty well. This arrangement also allows me to adjust the tension on the cable. It was a bit of a struggle tightening the bolts because of the position of the lock mechanism, there was no chance of getting a screwdriver down there so I had to use two pairs of pliers, one in each hand to hold the nut and tighten the bolt.

So here’s my finished job. It works pretty well although the action was a bit stiff which I don’t mind but it caused a problem that the return spring was not strong enough to pull the cable back which prevented the central locking from working. Even though I thinned down the cable it was still slightly thicker than the original so I just dumped a load of oil and WD-40 down it and hopefully I won’t have any further issues with it.

Overall, I’m pleased with the result.

For some time I have noticed two puzzling symptoms with this car:

1. The car sometimes lurches forwards or backwards, especially on the highway
2. Sometimes, but not always, the engine revs go up to 2000 rpm or more when stopped at traffic lights

I thought the first one must be mechanical, a worn bearing, excessive play in the 4WD system or something like that. The second fault had to be electronic since the idle speed is electronically controlled.

After doing a lot of reading of Subaru forums, car repair guides and whatnot, I realised that both these problems may be related and caused by a faulty Throttle Position Sensor. The high idle speed is because the engine computer thinks I’m pressing the accelerator when I’m really not, and the lurch happens as I lightly press the accelerator on the highway and the engine computer misinterprets it as me stomping on it – I went for a test drive to confirm this, the lurch even happens when I’m using cruise control.

So I had a look around some spare parts sites and eBay of course for a new Throttle Position Sensor. Now if I was driving a Ford, a new TPS would cost me $25. But a Subaru TPS? How about $400!

Not wanting to spend that plus another $100 to get a mechanic to put it in for me, I thought it might be worth just cleaning the thing. The TPS is essentially a potentiometer and being an electronics guy I know all about those and how they can behave erratically when they get a little bit of dirt or corrosion in them. Or it could even be the connector, dirt in there would certainly mess up the signal.

So the first thing to try is simply cleaning the connector. Before I did that, I had to locate the TPS. It sits on the throttle body on the opposite side from the throttle cable, it just looks like a small black box with some wires connected to it.

To remove the connector, squeeze the release catch while pulling.

I sprayed some contact cleaner in it and blew it out with some compressed air (not having a compressor, that means just blowing into it really hard and having the contact cleaner spray back into my face).

I reconnected the plug and went for a test drive. The car was much smoother. Problem solved in five minutes (if you don’t count the hours of research to figure out what to fix).

I’d call that a win!

Looks like a good job. It’s sure to work better than before!

Does this label imply that all other drink bottles contain leaded plastic?! What will we have next – Cyanide-free Weet Bix?

Yep, for those people who want a tyre swing for their kiddies but are unable to tie a piece of rope onto an old car tyre, you can now buy them pre-assembled at Bunnings!

import math

def cycle(centre, range):
        theta = 4.71
        speed = 0.1
        for i in range(0,80):
                theta = theta + speed
                value = centre + (range * math.sin(theta))
                print value

I got the following error which confused the hell out of me:

Traceback (most recent call last):
  File "cycle2.py", line 11, in 
    cycle(0.0,10.0)
  File "cycle2.py", line 6, in cycle
    for i in range(0,80):
TypeError: 'float' object is not callable

Can you see it? It took me a while. I’d assigned a variable called range and then tried to call the range() function. I’d overloaded a built-in function. Duh!

I just had to rename my variable and it was good.

I want to create a month-by-month summary of these figures. Here is the (rather complex) formula to make that happen:

=SUMPRODUCT(A1:A5>=DATEVALUE("01 Jul 2009");A1:A5<DATEVALUE("01 Aug 2009");B1:B5)

That formula will give the total of all amounts for July. By repeating this for each month, you can get monthly summaries for the whole year.

I’m still doing some contract work here and there but am spending most of my time looking after the kids and doing housework. To be perfectly honest, I’m enjoying it. Its really nice to take a break from full-time work, the first time I have not been working flat-out in about twelve years.

So where to from here? While kids and housework keep me reasonably busy, I’m not the kind of guy who can just sit around. So I’m planning to create some products for sale. I’ve set up a new site called siliconsparrow.com where I will base my professional operations. I am excited about the possibilities.

Unfortunately it means this blog will become a bit neglected. I’ll only be posting personal and hobby stuff here, and perhaps more housewife-related stuff like recipies!

Now you can get the same level of simplicity using inpout32.dll and Python. Go here to download the DLL and you can access it from Python just as easily as it used to be under DOS. The following example writes the number 5 to the parallel port:

import ctypes

ctypes.windll.inpout32.Out32(0x378, 5)

=if(A1<=6000;0;if(a1<=35000;.15*(a1-6000);if(a1<=80000;4350+(.3*(a1-35000));if(a1<=180000;17850+(.38*(a1-80000));55850+(.45*(a1-180000))))))

One of the little rules in our house is that kids are not allowed to watch TV before school in the morning.

But these two are so addicted to the glow of a screen, they watch my screen saver and pretend it is a movie!

Sometimes they are quite amusing to watch, they come up with things like “Oooh, watch out little blob, that big blob is going to get you” or “That’s two cows dancing!”.

My screen saver is Electric Sheep by the way.
