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.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however 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 price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

Retro-tech - The RCA CED Videodisc

Due to popular demand, I've made a video all about the RCA Videodisc system.

This was intended to be a quick and simple look at an obsolete technology, but somewhere during the course of the four problem-filled months that it took to put this video together, it went off the rails and ended up as a half hour video documenting man's struggle against machine(s).

It's like the youtube gadget-review version of Fitzcarraldo.

Some useful links:

CED Magic - The Website for everything about CED. Includes a full catalogue of every disc released.

The Full Electron microscope video on the Applied Science Channel can be seen here on youtube.

If you are interested in buying a CED player or discs on ebay - here are links for the US and the UK.

If you buy an old Hitachi player you'll need to replace those two rubber belts shown in the video. These can be purchased in the UK from CPC Farnell - here's the link

The old technology is always fascinating. After all we are talking about the pre history of home video.Thanks for another fabulous lesson of video gadgets history.

Really interesting. I only ever saw one of these discs in the wild. Great that you sat through the Muppet Movie in the interests of science - I'm going to try that one!

But surely there must be some way to clean them, or maybe replace the stylus with a laser to read them optically? ;)

When I worked int he consumer electronic field most of this technology was seen as too unreliable and destined to fail.
My engineer hated it. Remember we had already seen the Betamax system loosing out to VHS which was in reality inferior technology.
Customers used to ask us which was the best system to invest in and you could not give them an honest answer as they were all destined to fail.
Pioneer brought out the first proper digital video disks which was obviously better but could you recommend it to your customers when you saw Betamax fail.
The consumers were already becoming aware of the competition between competing manufacturers offering differing technology and wanted to know what was the best new system that would not be obsolete in a couple of years and the answer was nothing is forever. It is a long time since we saw Phillips and Sony get together to create a definitive standard that would go on for a long time. OK Sony decided to produce a recordable system called mini disk which would fail because it was not accepted as a standard in the consumer electronics world.
Perhaps this its the issue surrounding new high resolution digital audio formats.
Do you go for FLAC or WAV 24 bit or 32 bit etc etc.
It's tough life for consumers wanting to start a collection of anything and as you say it's all coming down to streaming and no physical copied at all.
I love your videos and I did ask do you accept pay pal for one off contributions ?

I'm fine - just keep enjoying the free content. If you feel like you must contribute in some way, if you do ever decide to buy anything on ebay or Amazon, use one of my links and then I'll get a bit of commission.

Another great review of a device I had never heard of before even I'm born in the 70's :) It's really nice to see these old machines getting repaired and working again after probably decades.

What an interesting video! Good job, Mat :)

Hi Matt, I've a possible small addition to power the core of your time machine. In the 60's, before Clive Sinclair ran over both feet with his C5 he used to churn out electronic kits, sold through the electronics hobby magazines. Some of them hifi orientated & above all cheap, which was my dad's main language.

One of these was the Sinclair Super IC12, High Fidelity Monolithic Integrated Circuit 6 watt Amplifier, a very early integrated circuit. My dad bought 2 of them, one of which is untouched in the original box. He made one of them up, but either didn't think much of it, or more likely fried the chip with a soldering iron that was too big.

What you got in the kit was an IC amplifier with bonded-on heatsink, the printed circuit board, and 4 pages of instructions. The normal circuit also needed a dozen resistors & capacitors rounding up oneself. As you're pretty good on your soldering any interest in taking it on?

The holy grail of unmade-up Sinclair kits would be the Micromatic radio, a 6 transistor job that was slightly smaller than a matchbox. I made one up & the audio volume was only slightly greater than the matchbox would have been.

There's actually yet another failed video disk format and that's CED. It actually recorded discs mechanically... and not just by moving the groove sideways, but changing the depth of the groove. Essentially it had kind of a slay shaped needle which would distribute the force evenly on a large surface while only reacting to the last height. Of course it only had 12 minutes (or so) per side and the disks would wear out. The quality was what you'd expect from your typical colour under system.

Thank you for the offer but unfortunately I'm can't find enough time to solder anything nowadays. I've turned down a couple of the newer projects from Spikenzielabs as I don't think that enough people would have enjoyed the finished product .

Thanks for the offer but changing the depth of the groove
