iPhone Bluetooth Headset meets washing machine

Posted by Jon Evans 26/03/2008 at 00h07

Well the inevitable has eventually happened, my Apple Bluetooth Headset has been put through a full 40°C cycle in the washing machine. Not only that, my iPhone stereo headset was in the other pocket.

The headset microphone seemed to be broken so I tried to pry it open to dry it out. I just managed to break the clips. After warming it up on my external USB drive all day it has dried out to the point where it might be working OK again, so I'm going to try a bit of superglue to fix the cover back on. In the meantime here is a photo.

Inside the iPhone headset microphone

My bluetooth headset is still in a bad way. It sort of charges up, but the indicator flashes orange. If you hold the button to turn it on, it does the usual four rising tones but it is very scratchy and crackly. It's also pretty beat up, as it came out of the pocket and rattled round the washing machine drum.

Here's some pictures.

The 'miracle' of vinegar

Posted by Jon Evans 13/12/2007 at 11h55

There are many web pages making grand claims for the number of problems which can supposedly be solved by using vinegar. One that I've read quite often is that you can prevent your car windows from icing up. For example, here's a quote from "Chef Noah":

Prevent ice from forming on a car windshield overnight.
Coat the window with a solution of three parts white or vinegar to one part water.

I decided to try it last night. I mixed white vinegar and water in the designated proportions, put it in a misting bottle, and sprayed it all over my windscreen and rear screen. Then I went to bed safe in the knowledge that I'd be leaping happily into my car in the morning and driving off while all my neighbours stared enviously at my frost-free car.

Well, I'm not very happy to report that this morning there was absolutely no change in the amount of ice on my screen. Furthermore, I don't even think it was a particularly cold night last night - it was only about -1°C when I went out to the car in the morning. Don't these sites test their tips before posting them? So I got cold hands as usual. Bah.

Rails-like 'flash' in Spring

Posted by Jon Evans 13/12/2007 at 01h56

I’m going to document this because it took me ages to work out, but in the end it turned out to be quite easy.

In Rails there is a useful thing called ‘flash’. Flash is a component which is automatically available in every view. Controller classes can insert a message into the flash object, and when it renders the view it can display the message. The great thing is that by default the message exists in the flash for two requests. This is so that the current request can be terminated with a browser redirect, and when the browser follows the redirect the flash message will be there waiting for it.

Read on for more details.

Adventures in plumbing

Posted by Jon Evans 17/11/2007 at 23h03

I fixed the cistern in our toilet this evening. For the last few months it has been making a noise like a tuba every time it fills up. Turns out the valve just needed dismantling and cleaning. While I was in there I found an alternative valve insert which the manufacturers had provided in case you have low water pressure. Well, our water pressure is really high, but I thought I’d give it a try anyway. I connected of all up and flushed, and it was an amazing spectacle. It filled the cistern with a deluge of water in about 20 seconds. I decided that the valve probably couldn’t cope with that long term, so I put the old one back. At least I silenced the toilet tuba.

I bought an iPhone last Friday. I arrived at the O2 store in Banbury at about 18:10. There was quite a party atmosphere with about 15 members of staff available, but there were only about 2 customers there apart from me. Nobody else bought anything while I was there, although I passed someone on the way to the shop posing for a photograph, beaming broadly and holding his "Got One!" bag for the camera to see.
