1996 Audi A4 (B5) 1.8

Today I sold my car. It was a 1996 Audi A4 1.8 (the naturally aspirated one). It was a great car that I am going to miss tremendously. Even though I’ve only driven it very rarely in the last year, every time I did I would remember why I loved it. It was voted SA Car of the year in 1996 and for good reason. Even though it’s 19 years old, the car still goes well, has many features, and in my opinion is still a good car by current day standards.

beach_audiThe car used to belong to my grandfather who looked after it with impeccable care. When he passed away my parents bought the car for me, and I’ve had it for the past 7 years. I received it at around 140,000km, and have put an extra 70,000km onto it since then. During this time it has only failed me once, and that was when the fuel pump packed in late at night on the way home from a show in Cape Town. Besides that I’ve only had to perform standard wear and tear replacements.

party_audiThe 1.8l engine put out 96kw when it was new, and has retained majority of that grunt. Although not over the top, it allows for comfortable cruising, and dropping a gear gives you all you need for overtaking or maintaining speed up a hill. The front-wheel drive, 5 speed manual car under-steered predictably, and minor tyre squeal from the 15″ tyres on stock mags would always let you know how close to the limit you were. Lean on hard-cornering was quite noticeable, but understandable. The car was absent of any ESP or traction control, but did have all-round disc brakes with ABS.

road_trip_audiThe radio was a standard cassette/radio, a CD shuttle in the boot was a later option which my car lacked. The radio only gave me hassles when the battery died and I didn’t know what the code was. I later also installed an RF transmitter into the dashboard to allow for some more modern audio input. The car originally unlocked with an IR remote. This had stopped working by the time I got the car, but the central working still functioned. I thus installed a garage remote receiver in the boot and hooked it up to the central locking system, thus returning remote locking to the car.

scenic_audiThe car is spacious with a large boot and even a full-sized spare wheel. The car had one airbag in the steering wheel for the driver, and other models came with a second for the passenger. 3 point seat belts for 2 of the 3 seats in the back, with a waist belt for the 3rd. The climate control still worked perfectly along with the rest of the electronics I haven’t already specified. In its latter years the catalytic converter was removed which gave the Audi a bit of a raspy warble.

nowhere_audiIt’s a great car, and can be picked up relatively cheap at current rates. Condition of the vehicle will vary a fair amount, and if proper maintenance hasn’t been seen to, you could be in for costly repairs. At 200,000km the clutch and gearbox still worked perfectly, and the engine wasn’t burning or leaking any oil.

New backwards compatible USB cable

Why hasn’t there been a USB cable developed that is reversible like Apple’s lightning connector? This is something that has bothered me for a while. There are a lot of jokes around the USB connector, my favourite being this one from SMBC.

But why can’t we have a reversible one. So I did a speed run through the 56 MB of documentation on USB 2.0, and can’t see any specific reason that this can’t be done. The only reason I’ve come up with is that there is a risk of shorting, especially if someone doesn’t conform to the standard. I also read on StackExchange, one person’s answer relating to USB specifications that the USB logo must be displayed on the top of the connector, something I feel can be easily overcome.

I have seen a prototype demonstrated before, and while nice, I don’t think it’s the simplest solution to the problem. I believe this solution makes use of a similar mechanism. Also I really feel a plug shouldn’t have moving parts.

So that leaves us with this:

I decided to test out Sketchup, having being spoilt with student version’s of Autodesk software throughout university, it was something new to try out. So excuse the poor animation and model.

In any case, I took an old USB cable and shaved off the casing to test out the feasibility of this option. And my initial thought played true. If you have contacts on both sides of the plug, on the side not connecting to the USB port, the contacts short with the springs in the port housing, which in practice would result in an overload warning from your computer, and the USB port shutting down.

2015-05-02 17.15.22

So, I can see why no one has done this yet, but I still think there’s a better solution than what we currently have. And I’m not convinced that my method, with some minor adjustments, can’t work.

Some funny things I found in the standards document include maximum insertion and extraction forces, of 35 N at 12.5mm/min and 10 N at 12.5mm/min respectively. Also a cable pull-out specification, because who is going to try grip a plug, when you can just tug on the wire :)

Logitech K750 – Solar Keyboard

For the past few years, ever since I got a laptop, I’ve used a laptop stand with a built in keyboard, and although a bit limiting as far as manoeuvrability is concerned, it’s worked quite nicely. It allows my screen to be lifted up, and puts it a bit further away from me, while also giving me a full size keyboard to work on.

It’s not an amazing keyboard but it’s done me quite well, until earlier this year when I upended a cup of coffee onto it. To it’s credit, after I stripped it, drained it, and cleaned off as much of the sticky stuff as I could, it continued to work. But the stickiness is still there, impeding my typing. And so I was looking around for keyboards, but couldn’t find one I liked.

I knew which keyboard I wanted, it was this one (Logitech K750). The solar powered one :) but it was R1,000. And I wasn’t going to pay that much for a keyboard. Ideally I was looking for a wireless ‘island’ key layout, much like my laptop’s keyboard. But I couldn’t find one in I wanted to buy..

And so I resigned myself to sticking to my sticky keyboard. Until Takealot had a daily deal and I picked the same keyboard up for halfprice, much to my delight. In typical Takealot fashion, they completely over-packed the box, but the keyboard itself comes in a slim box, with only the essentials. The keyboard itself is very thin, but with a surprising weight to it. It has some flex to it, and two spindly legs to raise it, but it all seems sturdy enough.

The keyboard has a nice gloss finish (it even comes with a cloth), with the two ‘large’ solar panels taking up space along the top of the keyboard. The keyboard makes use of Logitech’s unifying remote, and even comes with a small extension for plugging in the back of a desktop PC.

The letters on the keys are in the middle or slightly below the centre of the button, which makes it look odd, but obviously has minimal impact. One thing I am missing straight off the bat, is the lack of wrist rest. My laptop obviously has one, and my laptop stand also had a rather sizeable one. But I’m sure the lack of this will be forgotten in time.

A keyboard, below a keyboard, below a keyboard

A keyboard, below a keyboard, below a keyboard

The keyboard has an on/off switch, assumedly to spare a bit of battery and a ‘light testing’ button, which when pressed illuminates a green or red LED depending on how much light the panels are receiving at the time. The keyboard is also designed to never have its battery replaced. Only time will tell, but that’s obviously why we have the solar panels.

Overall a very nice keyboard that I’m happy with. The layout is ever so slightly larger than my old keyboard, so my fingers feel slightly stretched, but I don’t know if that’s actually true or if it’s just the lack of wrist rest that makes me think that. Now I just need to build a new laptop stand for myself.

Hypothetical what?

I like writing; it’s one of the main reasons I keep this blog going. And I’ve thought I’d like to write a book. But a book about what? I think it’d be amazing to put together a fictional book. But I struggle with this. To me it seems like one big hypothetical situation. And I don’t do well with hypothetical situations.

I’m currently taking German lessons, and often I find it frustrating, because I can make myself understood fairly well in English and Afrikaans, but when I get to German I run out of words quite quickly. That being said, when I talk with my teacher about what I’ve been doing, I can get through the conversations. But often to encourage dialogue she’ll ask me something like: “Imagine you’re wanting to sign up for a gym, what kind of questions would you ask?”. This is difficult for me, not because it’s German, but because I’ve never thought about this situation previously, now all of a sudden my mind is throwing 90% of its focus into trying to think about what’s important when joining a gym, (facilities, costs, opening hours, were the conclusions I came to), and only another 10% in actually trying to speak German.

This makes it sound like I have no imagination or creativity though. Which isn’t necessarily true. I just output these in different ways. But I’m on the verge of convincing myself that I wouldn’t be able write a fiction book. Which to me is a bit sad, because I grew up on a lot of fiction. I read a ton when I was young, during primary and high school. Dropping the ball a bit during varsity but picking it up again more recently. And fiction is awesome. It’s never ending; except for me in that I need someone else to make it up first.

The alternative, non-fiction, isn’t necessarily bad, but then I still have to figure out a topic. Most of what I write here is short stories about small events in my life, and I don’t quite see me getting to the point any time soon where I have an experience, or string of experiences worthy of a book. My girlfriend’s gran recently published an autobiography (From Kitchen to Cockpit by Yvonne van den Dool), a series of stories from her time as a female pilot during South Africa’s relatively conservative 1950s. I’d love to write an autobiography, but I don’t want to wait 50 years to have content to write one.

Then there are non-fiction books covering a specialist topic, but ignoring my masters, I’ve always considered myself much more of a ‘Jack of all trades, master of none’ type of person. I like knowing lots of little bits of information. Maybe I can figure out something from that. Hmmm…

So again I’m met with what I assume is most author’s perpetual problem, what should I write about?

xkcd: The Sake of Argument

I love discussing things, having disagreement for the sake of the conversation. I wouldn’t say this is necessarily making things up, but it’s interpreting situations and facts in a way that is most favourable for you, thus the above cartoon from xkcd . Maybe I can write one long argument.
