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%!

Answering a few Tefifon Questions

No one asked for here it is, another video about the Tefifon - that obscure vintage piece of German HiFi from the 1950s.

OK, in truth I've a couple of new items to show, some things I want to elaborate on and you'll also get to hear a sample of Tefi music recorded directly (over a cable) from the Tefifon.

If you want your own Tefi ringtone you can download my MP3s here - CHIMES   HORNS

What a strange but fasinating piece of kit.
Never seen anything like this before.
A four hour tape?! When records of the period lasted a few minutes?
It must have seemed like ground breaking stuff at the time.
Sounds quite good too, considering its age

Thanks for sharing it

Love the Tefifon videos. One thing that has baffled me is how they could mass produce the Tefis. After a quich Google, I found this

The process is as amazing as the playback machine.

Fascinating ! Thanks for another great video !

I have found someone selling more Tefi tapes on the supplied Ebay link, if this is of any interest to you?

May 9, 2015 | Unregistered CommenterNick Morton-Grant

Thanks for the link, but I think I've got enough Tefi Carts for the moment. All the things I've shown came from eBay, there's always plenty of items on offer when I do a search for "Tefi" and choose European or International.

Thank you very much for your video. It was very interesting.

I tried to download the WAV samples, but I can't open the files in any of my audio programs.

Could it be because I'm on Windows?

May 9, 2015 | Unregistered CommenterSamuel

Perhaps try the MP3s pretty much every device on the planet can play an MP3

May 9, 2015 | Registered CommenterTechmoan

I did download the mp3s, and they work fine, but I also wanted to listen to the lossless ones

Are you able to open the files from the archive?

Thank you anyway, if it's just my problem don't bother doing anything... I'll find a way.

The WAVs are just the MP3s converted to WAV. The original files were stripped from a MP4 video file to M4As then converted to MP3s. They were only uploaded to be used as ringtones.

May 9, 2015 | Registered CommenterTechmoan

Ah, ok. Nevermind then.
