I’ve been experimenting with a Sony ZV-1. This is a compact yet very capable camera, and if I wanted to purchase something explicitly for vlogging, this might well be it. Assuming I wanted to spend 700 quid in the process, of course.
Yesterday, I took it with me while walking the dog, and was really quite impressed. In the process, I produced a video which talks too much about a particular bit of Cambridgeshire for those who are interested in cameras, and too much about cameras for those primarily interested in walks in Cambridgeshire.
I fear the overlapping set in this Venn diagram may be rather small, but it was for my own interest more than anyone else’s; I’ll just put it here just in case there should turn out to be anyone else in that small and exclusive club of South Cambs Vlogging Dog Walkers…
Yesterday I realised I was looking particularly suave and debonair, so decided it would be the right time to point a camera at myself. Mmm…
If you want to try using a decent digital camera for videoconferencing, you normally either need:
something which will capture an HDMI output signal from your camera and feed it into your computer over USB, like the Elgato Cam Link,
or you need some software which can capture the live preview output and make it available to your operating system as if it were a locally-connected camera. On the Mac, I do this with a combination of Camera Live – which makes it avaliable as a ‘Syphon’ server – and CamTwist, which can take a variety of inputs, including Syphon, and blend them into a ‘virtual camera’ output. There are various tutorials online on how to do this. OBS is a similar popular app, but doesn’t yet support virtual camera output on the Mac.
Finally, for some versions of some Mac apps, you may need to remove the app’s signature (which identifies it with a certain set of permissions), to enable it to see virtual cameras as well as physical ones. At the time of writing, Zoom needs:
In October 1999, I was interviewed by Leo Laporte on ZDTV’s ‘Call for Help’ programme. Yes, this is just another interview about the Trojan Room Coffee Pot, but it’s interesting to me for several reasons.
Firstly because, even though it’s nearly 20 years ago, I’ve only just seen it! They kindly sent me a VHS tape of the episode at the time, but (no doubt with good intentions) they encoded it with a rather unusual 50Hz variety of NTSC, and I’ve never been able to play it. It was only last week that, before throwing it out, I went to the trouble of tracking down somebody who was able to tell me that, yes, indeed, there was actually something on the tape…
Secondly, it was quite a challenge to do the recording. They sent me a camera in advance, and I had a slightly older PC which didn’t have the brand new USB ports that were just starting to appear, so I had to dismantle it, install an ISA card, and then repartition my hard disk and install Windows 95, because neither the Linux nor the Windows NT operating systems I had on there were supported by 3Com’s software.
But chiefly, it’s a nice nostalgic snapshot of tech life not too long ago. The rest of the episode provides helpful hints like: you’re probably used to installing hardware in your machine before inserting the CDROM or floppy with the drivers, but with USB it’s a good idea to install the drivers first. Files you download over your modem may be compressed and you’ll need a thing called WinZip to see what’s inside them. And Chris Breen (later an editor at MacWorld), comes on to explain that if you’re trying to play DVDs on your computer and they keep skipping, it may be because you’re connected to a network that does something called DHCP. The PC can’t do that and play back smoothly at the same time, so it may be worth disabling DHCP before you start watching. Oh, and there’s also a section about how, if you have a laptop, you may find it a pain to be tethered to your modem, but there are some wireless networking options becoming available, and the one that looks most promising for the future is this thing called 802.11…
The clip I’ve uploaded shows the interview from the studio in California, with me in Cambridge, and we’re joined by Don Lekei from Canada a bit later. It’s hard now to remember just how rare it was at the time to see people on TV live from remote locations. That normally needed satellite linkups, or very costly kit attached to extremely expensive international ISDN calls. For Don and I to talk casually from the comfort of our own homes on opposite sides of the world was enough to get the hosts of a tech show pretty excited. You’ll note that we both use telephones as well, though, because there wasn’t any suitable audio channel…
Anyway, Leo is now the head of the substantial TWiT netcasting network, so I guess networked video worked out well for him too 🙂
Just before Christmas, Tilly (my spaniel) and I went to the Dordogne and back in our campervan. I made a video about it, which, while it may be of interest only to travel vlog and ‘van life’ enthusiasts, does have a bit of novelty value, because I filmed it on a spherical (360-degree) camera.
This means that after you’ve watched it, you can go back and watch it again from a completely different angle and see what was happening behind you!
I’ll put the link here, rather than embedding it, because this is something you want to watch on the YouTube site. Or, better still, in the YouTube app on your tablet, or phone, or VR headset…
Here’s a little video selfie of me breathing. Pretty exciting stuff, eh? The reason I look so strange is that it’s taken with a thermal camera: the white and yellow areas are warm, the blue and black ones colder. I haven’t decided whether or not it’s an improvement on my normal appearance.
One reason for our interest in this at the Lab is that you can clearly see my nostrils getting cooler as I breathe in, and warmer as I breathe out. So a thermal camera is a pretty straightforward way for a computer to measure my breathing rate.
But I had some fun playing with the camera at home, too. Pointing it at my hall floor showed glowing tracks where the hot pipes run under the tiles, allowing me to see how the radiators in different rooms are connected up.
When I was looking around upstairs, I noticed some light patches on the floor and wondered what they were. It took me a moment to realise that Tilly had trotted up behind me to see what I was doing, and had silently departed, leaving only warm paw-prints behind her as evidence.

Last night we went into London because the kind people at the Lovie Awards, the European branch of the (rather better-known) Webby Awards, had been good enough to give me an award, mostly for the work that friends and I had done in creating the first webcam.
I was a bit embarrassed about this, partly because I didn’t think I deserved it, and partly because of the name, but I got over the latter, at least, when I discovered that it’s in honour of Ada Lovelace.
Anyway, the tradition is that you have to give a little speech containing the word ‘Love’. The other tradition, which nobody told me, is that the speech should be about 30 seconds, which is why I look a bit more flustered than usual here! I was trying, not very successfully, to edit my speech on the fly. But I got away with it because mine was the last award of the evening.
It was a great and responsive audience, which, sadly, you can’t hear on this video.
