Tools of the Trade

TOTT

You may have really good eyesight that allows you to see small things up close, in which case you won’t need the glasses.

I use ALL of these tools for TCs. Strangely I seem to have missed off my
multimeter; very necessary when checking the PSU. So now you know... :-)

Multimeter DL92

Do-it-yourself

My dictionary says that this is an adjective and
‘Done or to be done by an amateur at home’.
Well, I have been asked by a few hardy souls how to remove bits from errant TCs that can then be sent packing - literally, via whatever postal system exists out there, BUT WITHOUT RISKING the internal hard-drive and all the precious data.

Look at the very bottom of this page and you shall find that which you seek!

I have also been asked more than once, where to get the various components to fix the PSUs...

Try this list... (or buy the Capacitors from me! The ‘COM’ option)

I hope it helps?

Eutechnics

My dictionary lists ‘Eutechnics’ as being a well arranged system of work. That’ll do for me!

La Pastenague

When my Time Capsule died, it was a real shock that something 'Apple' should do this, after all "Apple's just work".  
Having trawled the web for immediate help (probably as you have done) and been advised by Apple that it was” out of warranty", I decided to do something about it on my own.  
I was guided, as so many have been and so many more will be, by the 'La Pastenague' website, into rolling up my sleeves and doing it myself.  

25 years of engineering inactivity fell away and my skills from years ago became re-established again.  
My ability as a design engineer and circuit builder was not really being tested here, as Time Capsule design is mostly excellent. (But with added ‘flaws’ for extra excitement!)

However, seeing what the problem was and putting myself back a number of years, I could imagine how the 'problem' occurred; it is not too hard to 'fix the omissions'.  
The internal fan has no air input, is pointing the wrong way and does not turn on. Some experimentation resulted and I passed my thoughts, with pictures to Ray Haverfield in Australia.  
The man is so wonderfully practical and unflustered that his reply and response to my first faltering steps still reads well months later.  Ray advised putting an external power supply in place and even recommended the type.  
He was then and is now very generous.

Through him I have contacted Dale in the USA, Murdoch in the UK and Meherally in the UAE, all of whom I would regard as good friends, albeit via the Internet.  We may meet one day.

However, Ray may well have been lucky and just “in the right place at the right time”, but he gets my grateful thanks that I am very happy to make public. I know I am not alone in this thanks. Ray, you are one of a kind! :-)

His site contains some of my work.  In the spirit of friendship and cooperation I link to his site from here:

I suspect you may have heard of this website;

The Apple Time Capsule Memorial Register


A tale of 2 TCs.

On the left is a DELTA supply unit with a 'green' 1TB drive in a Eutechnics ’modified’ case with the fan turned round.

On the right is a unit with a Flextronic PSU unit with a 500GB drive.

The two units were allowed to warm up for 2 hours, both are merely ticking over and no disc access is being made.

The PSU areas of each show the greatest heat generation, with a 10 to 11 degree C difference.
(The table top is at 20 degrees C.)

This picture really says it all I suppose.
Tests will continue showing internal temperatures.

I hope you find these interesting?

A Little something to help while away about 4 minutes of you life...

This is the piece of music I use when blasting hot air from my nice new air-gun, before removing the rubber base mat. Before my air-gun I used Fiona’s spare hair dryer, which is nowhere near as hot as the air-gun CAN GET. So it was very necessary to apply a lot of heat to the base of the TC. Heat is the quantity of accumulated energy that will soften the super-claggy (special technical word) glue that sticks the rubber base on. You MUST BE PATIENT and with a hair dryer apply heat for between 3.5 and 4 minutes. Honesty, this is the BEST way to remove the rubber mat without tearing it. The TC will (and should) become uncomfortably hot. Take your time pulling the rubber mat away - allow about 1 minute to do this. That glue needs time to loosen its grip.

If you use this tune as the time necessary to do the job, and go to-and-fro with the rhythm, it will soon be hot enough to behave itself... enjoy!

The tune is called ‘Suddenly’ and is by my Writer/Musician/Film-making son, whose Copyright it is. ‘The Fatt Mackrell’.
