Lesser-known uses of the Apple Watch

Camera Remote on an Apple Watch

I was doing some electrical work on the lights in our guest bedroom this morning, and wanted to turn the power off at the fuse box before I did so.

However, we have a lot of circuit breakers, and, though I have most of them carefully labelled, the three controlling the upstairs lights were not among them. So I was expecting to do a fair bit of running up and down stairs to see whether the one I had switched off did in fact control that particular light.

“There must be a technological solution to make this less energetic!”, I thought… and then remembered that my Apple Watch has the ‘Camera Remote’ app, which can give you a remote viewfinder for your phone’s camera. So I put the phone on the bed pointing up at the light, trotted downstairs, and flipped switches until my watch showed that the light had switched off. Perfect!

(I was feeling very pleased with myself for this solution, and only rather later did I remember that, since all the lights in the house are under the control of my Home Automation system anyway, I could simply have looked at that to see when the light had gone offline! But perhaps that wouldn’t have happened quite so instantly.)

Making ‘social’ social again?

Back in about 1996, I was attending a conference in San Francisco. As we walked into the Moscone centre to register, we were all given not only the usual branded bag and bits of paper, but something much more exciting: a box containing what was to become my first true pocket-sized mobile device, the recently-released Palm Pilot.

Palmpilot professional cradle.

I don’t know whose idea it was to give these to everybody attending the conference, or how the finances worked, but it was a brilliant move. Not only was it an exciting surprise, but we immediately had an application for it: the conference proceedings were available on it, and you could slip it into your back pocket; something you certainly couldn’t do with the paper equivalent. And there was something more important, which I’ll come back to in a moment.

But for those less ancient than me, I should perhaps explain that what was brilliant about the Palm Pilot was the things it didn’t try to do. It had been preceeded a couple of years before by the Apple Newton, for example, which was a lovely device, but just tried to do too much and was thus expensive, large and heavy on power. The Palm guys realised that what people really wanted was just a cache, in their pocket, of the stuff they had on their PC. (Laptops were heavy, and expensive, with a short battery life, and you had to wait for Windows to boot up before you could check someone’s address. You might have one in your hotel room, but you probably wouldn’t carry it around.)

With the Palm devices, though, you would create and manage most of the content on your computer, which had a proper keyboard and screen. When you got back to your desk, you’d plug the device into its cradle, press the sync button, and any changes would zip to and fro, after which you could unplug it and put it back in your pocket. If you had migrated away from paper diaries and address books to keeping data on your PC, this allowed you to have that information back in your pocket again.

But you did have to plug it in to its cradle periodically, where it could talk to the PC using an RS-232 serial port. This was before 802.11 (the standard which, several years later, would become known as ‘WiFi’) and the Palm Pilot had no other networking. Well, almost none.

And that was, I think, really important.

You see, the lack of WiFi meant that it couldn’t distract you all the time with incoming messages. You could read email on it, but only the email that had been received on your PC when you last plugged the two together. So you would actually listen to what was being said at the conference: something almost unheard of these days!

But the device did have one further trick up its sleeve: it had infrared capabilites. It could exchange information with other Palm Pilots (and later with some other devices), using the same kind of line-of-sight connection that TV remotes used. That meant that for me to get your address and you to get mine, we needed actually to have met and collaborated in the exchange. I could send you my contact details across a conference table or while having a drink at a bar, in much the same way I could give you a business card, but it was so much more convenient because there was no need to transcribe the information afterwards if you wanted it in digital form.

This did require both of us to have Palm Pilots, of course, so what better way to kick this off than to make sure that, at a few key tech conferences, almost everybody you bumped into, for several days, would have one in their pocket?

Back in the early days of LinkedIn, there was a similar culture of only linking to people you actually knew; in fact, not only knew, but endorsed. I joined the beta release back in early 2004, and to this day I normally only link to people I’ve at least actually met, though in more recent years I’ve extended that to include ‘met on a video call’ or ‘had really quite a long phone call with’.

Nowadays, I do sometimes wonder why I’m still on LinkedIn, since it’s the source of more spam in my inbox than anything else. I’m not really out hunting for jobs. I’ve always joked — and it’s almost true — that I’ve never got any job I applied for and I’ve never applied for any job I got. And I’m not recruiting people either at present. LinkedIn is very much a work-related system, but having dropped in to the website just now for the first time in ages, I must confess that there was more interesting content on there than I expected, perhaps because it is linked to people I actually know in real life.

(Increasingly, social networks are things I visit in the same way I might visit parties; drop in for a while, see what the atmosphere is like, leave if it doesn’t appeal, but maybe visit again a few weeks later. I’ve just deleted the Twitter app from all my devices because I realised I could still drop in there using the web if wanted, but I didn’t need its content, or its notifications, delivered to my pocket.)

Anyway, I was thinking about all of this as I read Ev Williams’ article, Making “Social” Social Again, in which he announces the launch of Mozi. This is meant to be a social network to help you with your actual social life (and not a ‘social media’ platform). It’s about getting and maintaining up-to-date contact information for your friends, and knowing about their travels so you could meet up with them.

I don’t know whether it’ll succeed. There’s always the problem of bootstrapping a network when you can’t, say, give several hundred people a sexy new device that they’ll all be carrying around in their pockets for a few days. But it would be good to have something that is primarily about contacts rather than content, and yet isn’t primarily about work.

And he reminded me about Plaxo:

As I was making my birthday list, another, more practical, thing struck me: I had no go-to source for knowing who I knew. No online social network reflected my real-life relationships. The closest thing, by far, was the contacts app on my phone.

And, boy, was that a mess. I’m guessing, yours is too.

Why?

Twenty years ago, there was an internet company called Plaxo. There have been others like it, but Plaxo was the first big online address book. I remember thinking it was one of those simple but profound twists on an old product that was now possible because of the internet, i.e.: Why do I have to keep details up to date for hundreds of people in my address book? Now that we have the internet, you can update your address in my address book, and I only have to keep mine updated.

It was an obvious idea. And here we are, 20+ years later, with address books full of partial, duplicate, and outdated information.

Anyone encountering the same problem while writing Christmas cards?

The problem with Plaxo was that it required you to upload your address book to their servers, and I always felt uncomfortable with that. When someone gives you their details, their is an element of trust involved. They might not want you to broadcast their home address to the world, and they’re kind of assuming you won’t.

But nowadays, most people do this anyway, they just often don’t know that they’re doing it. It’s one of the reasons that, for a long time, I didn’t want to have anything to do with WhatsApp, Facebook and Instagram. But I abandoned my principles last year when I realised that all those friends I was trying to protect were already using those services and so all of their contact information was there anyway. And, because of them, so was mine. GDPR, eat your heart out!

Signal, in contrast, has a much better system which allows them to discover whether your contacts are on Signal without actually uploading your address book. In a world where we have these kind of techniques, and end-to-end encryption, and protocols for sending contact information, why is it that I can’t give you the permission to update your entry in my address book without my address book being stored on someone else’s servers?

I don’t know if Mozi will enable that. If they do, then I’ll believe we’ve made some progress from last millennium, when I could send you my current information with a couple of clicks and a beam of infrared.

The FreshWash Clip – Every home should have one!

This afternoon I went into our little utility room, made some measurements, and created this beautiful work of art on my iPad:

Rough sketch of clip

I then went upstairs and opened up my CAD program, where I was able to turn it into this:

Flat sketch of clip

And extrude it into three dimensions, so it looked like this:

whence I could 3D-print it, to get this:

Now, as most of you stand amazed, there may yet be some readers for whom its use isn’t immediately obvious, so I should explain.

If, like us, you don’t have kids, and therefore don’t need your washing machine to be running 24×7, the seals and the inside of the drum stay fresher and nicer if you can prop the door open and let them dry between washes.

And so I created the FreshWash Clip™️.

It works perfectly, and I get a deep, if childish, satisfaction from it. The hole on the top makes a bit of a handle so it’s easier to clip on and off, and can also be used to hang it on a hook on the wall.

This particular model is sized precisely for our elderly and out-of-production model of John Lewis washing machine, so I doubt I’ll be producing it en masse, but no doubt Chinese entrepreneurs will seize the opportunity to prove a whole range of different sizes and colours, and on Etsy you’ll soon find artisanal variants lovingly crafted from bamboo.

And as FreshWash Clip mania takes hold, and no home can be considered complete without one, please remember that you saw it here first!

Five years before the iPhone

Trying to organise some of my old video footage recently, I came across a little demo I recorded of the AT&T Broadband Phone, a project we started in 1999 but which, sadly, died, along with the research lab that had created it, in 2002.

Looking back at it now, I notice how slow-paced it is compared to the typical YouTube video of today! So if you watch it, you might need a little patience! Nonetheless, it’s quite fun to see some of the ideas we were considering back then, five or six years before the launch of the iPhone… things like the suggestion that streamed music “might be a service offered by a record company, where you pay a small amount for each track”, for example…

(P.S. I had an idea I had written about this here before… and indeed discovered that I had… but not since 2008, about eighteen months after the iPhone was launched.)

Well, I finally folded…

I’ve wanted an e-bike for ages, ever since I first tried one many, many years ago, but most of my normal cycling destinations are close enough that I didn’t really feel I had an excuse to buy one.

But then we started to think that folding bikes would also be useful when campervanning, and so the idea started to grow of getting folding e-bikes… and we are now the proud owners of two Eovolt “Afternoon”s.

Interestingly, we just rode these and found we liked them slightly more than the others we tried, but when we got them home and started looking for reviews, accessories, etc found they seemed to have comparatively little presence online (at least, in the English-speaking world). I certainly hadn’t come across them on YouTube, for example, when researching possible brands. So here’s my modest attempt at rectifying that!

A greener buzz?

When I was young, electric toothbrushes were something we laughed at. Imagine being too lazy even to wiggle a toothbrush up and down without powered assistance! But as an adult, I discovered that most dentists now thought they were rather good, and recommended them.

Electric toothbrushes did a better job of cleaning in general, they said, and the smaller head would get into places that manual toothbrushes wouldn’t reach. Perhaps, I thought, gadget enthusiasts like me shouldn’t feel embarrassed about actually trying one. I wouldn’t have to admit it to anyone..

“There’s a huge range”, I remember my dentist telling me. “Don’t go for the ones with silly prices and dozens of bells and whistles. 40 quid or so is probably about right.”

So, for a while, that’s the kind of thing I used. They’re probably about 50 or 60 quid now. They have a rechargeable battery, sit on a base that charges it inductively, and have a simple timer to help you spend the right amount of time brushing. You know the kind of thing.

But one thing about them always bugged me: the batteries were rubbish.

Long before the motor or the casing gave up the ghost, the built-in, non-replaceable battery would die, or stop holding enough charge even for one brush, and the whole thing would have to go in the bin. Then I’d buy a new one, which came with its own charging base, so the previous base, and cable, and plug – they all went in the bin too.

This was not very good for my wallet, and a great deal worse for the environment.

So I expect you will laugh, gentle reader, when I tell you that what changed my purchasing habits was brushing my dog’s teeth. Yes, our spaniel gets her teeth brushed every night, and she enjoys her chicken-flavoured toothpaste, but won’t tolerate brushing for very long, so we got her an electric brush, too, to make maximum use of the time available!

We weren’t going to buy her any big 60-quid devices, though, so we looked online for ones designed for children, and Tilly now has a children’s Oral-B toothbrush. It’s pink and blue and I think it has fairies or princesses or unicorns on it, but she doesn’t seem to mind.

And as we used this, a few things struck me:

  • The motor mechanism looked as if it was just the same as my own expensive one.
  • It took the same brush heads.
  • It used replaceable AA batteries. I had plenty of rechargeable Eneloop AAs. (Take a look at my post from about 10 years ago to see why I like those. I’m still using much the same system now, and most of the batteries I had back then are still in use.)
  • This also meant I didn’t need to have charging bases and cables in the bathroom.
  • It didn’t have a timer. But I could count elephants.
  • It cost about one quarter of the price.

And so I now have, and can recommend, a very basic Oral-B battery-powered toothbrush. Currently £14.99 on Amazon. It has lasted longer than my previous expensive ones, and the two AA batteries hold their charge way longer than the built-in ones ever did. Occasionally, I take them out to charge and swap in some fully-charged ones from my drawer — that’s why I love Eneloops and similar rechargables: they stay fully-charged in the drawer — and freshly-charged batteries seem to last for weeks.

Since I got this, some years back, nothing has gone in the bin except the occasional elderly brush head, and when it does eventually die, it’ll be far less wasteful than something that takes its batteries and charging base to the grave with it.

Oh, and best of all? Mine doesn’t have any princesses or unicorns on it. Tilly is still bitter about that.

Dumb switches and smart lights?

Almost all of our lights are now ‘smart’: controllable by software, timers, motion sensors etc as well as switches.

If you’ve done this, though, you’ll know there’s a problem: how do you stop people turning things off at the wall, at which point your smart lights become remarkably dumb?

Here’s how I do it:

With great power…

Back in the early days of USB, my friend Andy Fisher and I were bemoaning some of its design flaws as a communication system.  “But”, he pointed out, “USB is the first universal power standard”.   I laughed, and agreed. People didn’t really think of USB as a power source very much then, so this was an interesting observation.  

Andy and I were doing a lot of flying to places with different mains power standards, and we had phones from people like Nokia and Motorola, so we had to carry lots of chargers with a wide range of connectors and adaptors everywhere we went.  The idea of a predictable socket giving you predictable power was very appealing, even if it was only 5V at 1A. (Though I later realised there was perhaps one earlier holder of the ‘universal power standard’ title: the car cigarette-lighter socket.)

Screenshot 2023 09 21 at 09 38 18This week the news is full of the fact that Apple are switching the iPhone to use USB-C.  This is assumed to be largely the result of EU directives compelling them to do so, but my latest iPad and laptop from them are already USB-C, so it was probably inevitable anyway.  Personally, the ‘Lightning’ cable has always worked very well for me; I’ve never had one fail and on the rare occasions when I plug it in my phone and it doesn’t charge, the solution is invariably to remove the pocket-fluff in the socket (which, by the way, is best done with a wooden cocktail stick).  So for many people, whether you approve of the change probably depends on whether you have bought lots of Lightning-based accessories in the past, and how that balances for you against not having to do so in the future!

USB-C, on the higher-end phones, will give much faster transfer rates, which is important for those copying substantial video clips to their laptops, but probably irrelevant for most other people.  And USB cables can be highly confusing, because you can run other protocols over them alongside the USB communications; DisplayPort being a key example, but also including things like Thunderbolt and PCI Express.  When you plug a cable between two USB-C sockets, therefore, it can be hard to know what you’ll actually achieve: the projector in this meeting room has a USB-C socket, but will that allow me to display my presentation or just charge the remote control?  Might it even recharge my laptop for me?  Make sure you try it in advance, because you can’t tell from the sockets, and it may also depend on the quality of cable you use to connect them.  Plugging things together will almost certainly be a safe operation, but it may be a disappointing one.

Sometimes, though, you can get a pleasant surprise.  I remember when I wanted to connect a small stick-type computer to my monitor, and plugged in a USB-C cable to provide the DisplayPort video connection, only to find the computer booting up because the monitor was also able to power it, through that same single cable.

And while I still regularly complain about USB in general — I have two or three hubs on my desk to connect all my peripherals, from reputable manufacturers, yet I regularly get messages about some external drive being improperly disconnected, or find some camera needs unplugging and replugging before it appears in Zoom —  I do have to admit that USB-C, at least from the ‘universal power standard’ viewpoint, does seem to work rather well, so I’m in favour of this change for technical reasons, as well as environmental ones.

If you want to know more about USB-C power, what it can do and how it does it, I recommend this Hackaday article by Arya Voronova.  He points out that there are still some issues — if you plug your battery power pack into your laptop, for example, do you expect the laptop to charge the battery, or the other way around? — but overall, it does seem like progress.

The shelf behind me in my study has three large boxes labelled ‘Power Supplies < 12V’, ‘Power Supplies 12V’ and ‘Power Supplies >12v’, because I always hated throwing them away.  In the past, power supplies generally died more regularly than the things they were powering, and it was very satisfying to be able to reach into one of these boxes and give a computer, drive enclosure or ethernet switch a new lease of life.

But I think it may be time for a clear-out.

PSU boxes

I now have a reasonable number of adaptors to connect USB-A to USB-C sockets and vice versa, and this should work in most simple cases. But you’ll get the lowest common denominator of the two standards, which may not be enough. Just last week, I was installing a new phone mount in my campervan; one that would hold my phone in place magnetically and charge it wirelessly. The Magsafe wireless charger came with a USB-C cable and I just plugged it, via an adaptor into to the USB socket on my dashboard. But… Nada. It turns out that the wireless charger needs more power than a standard USB-A socket can provide. I did actually need to plug it into USB-C.

Fortunately, that was easy to solve. Because my dashboard is also fitted with the original universal power standard. A cigarette lighter socket.

Watching the clock

I’ve written several times about my enthusiasm for the Apple Watch, but even eight years after getting my first one, I’m still discovering uses for it.

We’ve spent the last few nights in our campervan on a delightful small campsite in Devon.

Picture of campervan in a bucolic setting

There are loo and shower facilities in a nearby building but, unusually these days, you do need to insert a pound coin if you want to use the shower. It’s a fine shower, and I didn’t mind paying, but since the meter is outside in the corridor, you don’t get any warning before the water shuts off suddenly after six minutes, possibly leaving you rather soapy…

So even in this low-tech environment, where we treat an electricity supply as something of a luxury, there’s great benefit to be derived from a waterproof watch which can be instructed, with a couple of clicks or a spoken command, to warn you shortly before your shower is going to finish!

Zappi Days

When I installed my home solar system, I also replaced my perfectly-functional car charger with a new one: a Myenergi Zappi. Why?

The Zappi is a popular charger, designed in the UK, and rapidly finding favour in other parts of the world. Here, I talk about what it can do, things you might need to take into account if connecting to a car like the Tesla, and a little bit of magic geekery I set up to make it fit my needs even better.

You are my sunshine…

We’ve just had a solar/battery system installed, and because I’ve spent a lot of time planning and thinking about this over the last year and a half, and because it has some slightly unusual aspects, I decided to create a video about it.

This starts off as a pretty basic introduction of solar power, and ends up going into some detail about why mine is arranged the way it is. This means that it’s longish… but I hope it might be of interest to anyone considering installing, or expanding, a similar system.
