What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.

VERY IMPORTANT. These links go to the product, but Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the going rate for a real item against the price of a fake one that won't work.

As an example of the extent of the problem of fake goods online...In a recent survey by Apple - 90% of the 'Apple' chargers sold by Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

'Seiko' Executive Talking Egg

Whilst searching for a watch a while ago using the term 'Vintage Seiko' - I stumbled across the Seiko Executive Talking Egg. Unable to determine any more information about the product I picked it up to see exactly what it did and how it worked. You can find out in the video below. 

In the video I mentioned that this product doesn't have the usual Seiko quality that I'd expect. It seems it was branded by Seiko US but manufactured by another company. The base has the word Sekisui printed on it, which likely refers to the Japanese company Sekisui Plastics, a manufacturer that has been around since 1959 and could have produced the outer casing. 

A number of people have suggested it might not be an official Seiko device, but there's no evidence to back up this supposition whereas the box and instructions (copy below) refer to Seiko. It's all academic, it's a rare 35+ year old device you can't buy any more and whether it was made by Seiko or Techmoan Electronics Corp doesn't make a jot of difference to the fact that it is still an unusual product that was very much of its time.

Laserdiscs aren't back - but their sleeves are

No one wants physical copies any more, people don't like packaging cluttering up their house...we've all gone streaming now, you don't really own anything, it's in a cloud somewhere....controlled by someone else. At least that's what people like to tell me. 

Well call me old fashioned (because I am), but I like packaging, I like holding the things I've bought and when I do pass on, I want someone to be extremely inconvenienced by all the detritus I've accumulated during my existence.

One of the things they'll have to figure out what to do with, is an ancient silver disc called a blu-ray...but it's not just a normal blu-ray film in a flimsy plastic box with broken catches and a thing that no longer grips the centre of the disc properly because a couple of the teeth got snapped off in the it's in a big cardboard square the size of a vinyl LP. Watch the video below to find out more. 

I really hope this laserdisc style packaging idea becomes a trend, and while I'm 99.98% sure it wont, I applaud Disney for having the guts to give it a try. Purchasing links below.

Star Wars the Force Awakens
Finding Dory

UPDATE: A few people have advised me that there are a number of Spanish releases of blu-ray titles in Laserdisc sized sleeves - click here to take a look

Music to watch Oscilloscopes by

Sometimes my videos form a bridge between the mainstream and the obscure. People often suggest video topics to me, and then that video in turn introduces a whole new audience to the subject. I suspect oscilloscope music will be one of those things. 
During the years I spent searching for a HiFi component with a scope output, I watched a number of blurry handheld videos of various devices on youtube. One one occasion I saw a Marantz receiver displaying a revolving cube on the scope display. At the time I presumed that someone had altered the circuitry, but I now know that they were playing an oscilloscope demo.
Oscilloscope demos have been around for a while, but until recently I wasn’t aware of them, and I spend at lot of my time looking at tech. Of course using oscilloscopes unconventionally is nothing new, the 'first video game' Tennis for Two used one as the display in 1958.
I suppose things like this are inevitable whenever you combine intelligent people with time on their hands and a room full of scientific equipment. Nowadays you can even play Quake on an oscilloscope
Displaying images on an oscilloscope is as ‘simple’ as playing sounds into it. The left and right audio channels create shapes plotted on x/y co-ordinates. 
I don’t truly comprehend exactly how it works, it just looks like magic and when you add in the additional complication of having those sounds form tunes, all I can do is sit back and admire the show. 
Watch the video below to see this in action. If you want to skip the introduction and repair section and just watch the scope, jump to the 5 minute mark.

HP-01 In 1977 HP invented The Best Watch Ever*

I’m a middle aged man. At least I am if I live to be in my 90s. I do middle aged man things, like go on cruises for my holidays. In truth, it's the only way I can get abroad since I’m no longer able to use air travel (health, not terrorism related). There’s a weird aura that permeates cruise ships, it’s a presumption that the passengers are wealthy. There’s always a high end jewellers shop on board selling watches that cost thousands of pounds, the ships dock in towns where every other shop sells luxury jewellery and watches to accommodate these deep pocketed visitors.  I’ve never understood why things are this way, it all seems like theater to boost the ego rather than an accurate reflection of reality as the average cruise ship passenger is anything but wealthy. When you work out the cost per day including meals, a cruise is often as cheap if not cheaper than going to a mid range hotel in Mallorca. 
Anyway I digress, the reason I mention this is that years of looking in the windows of expensive jewellers (often just to kill time) has programmed into me a desire to own a quality watch. I’ve been obsessed by timepieces all my life, however when I do kick the bucket, there’s no Rolex to bequeath in a will, but there’s plenty of Casios for someone to put in the bin. 
I recently decided that I owe it to myself to own one quality timepiece in my life. However I soon realised that none of the watches I could afford appealed to me. If I’m spending serious money then it has to be something that I would really cherish. 
So after looking at watches that cost thousands of pounds but didn’t excite me, I ended up buying a watch that cost a few hundred pounds, but one that means a lot more to me than just the money. The Hewlett Packard HP-01 is a unique and fascinating piece of history. Watch the video below to learn more about this amazing timepiece.

*it is as far as I’m concerned. As someone who likes 1970s LED watches, calculator watches, and values technical achievement.... this for me is the BEST WATCH EVER. If you prefer watches that have a waving Mickey Mouse on will probably have your own choice of 'Best Watch Ever'.

LaMetric Time - WiFi App Enabled Smart Clock

The number of internet connected household devices keeps increasing and many of these these devices communicate through notifications sent to a smartphone. For example a security camera will send an alert if the motion sensor has been triggered. 
There are many people who walk around head-down constantly looking at their phone like a Star Trek away-team crewman scanning a planet for anomalies. I'm not one one those, my phone might be on the table, in a pocket or most likely - on charge, so if a connected device sends a ‘notification’ to my phone, I have to make an effort to get the phone to read it.
The sci-fi visions of the future I remember enjoying as a child always involved information being presented to a person wherever they were. A mirror in a bathroom would remind the protagonist to pick up cat food after work, the television wall in the lounge would show when there was a caller at the front door. In none of these scenarios would the person just hear a beep and then have to go and pick up a small device, then press a button on it in order to see what that initial beep indicated, only to discover it was just another email.
The LaMetric Time is more like the future I wanted, glanceable information visible across a room. The video below explains a bit more about what this device can and can’t do and there are links below the video that you might find useful. 
The LaMetric time can be purchased from Amazon UK or Amazon US  as well as directly from the manufacturer (where it ships from Hong Kong). I must stress how important it is to look through the apps currently available to see if any suit your needs. I also have no idea how much ongoing support this will have, and like all internet connect devices that's really a vitally important component.

Behind the scenes - how to make a 5 second channel ident

I made a behind the scenes video for the Patreon contributors as a thank-you for their continued support. I'm also posting it here, however it's not going public on youtube as I don't feel everyone could cope with the fly-on-the-wall nature of the production. 


Dashcam Review: Viofo A119 - Simple Capable Capacitor Camera

The A119 does everything that many people need a dashcam to do. It records high quality video at resolutions including 1440p30 and 1080p60. It has great low light performance, uses a capacitor rather than a battery (more suited for hot countries) GPS is optional and the camera can be neatly mounted at the top of a windscreen.
