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: Audio Timers

Audio timers were used in the 70s and 80s to automatically activate a tape recorder at a pre-determined time. Nowadays taping off the radio has fallen out of fashion but these timers can still be put to good use as a retro alarm clock or a way to automate electrical devices around the home. Watch the video below to see a new-old-stock late 1970s Pioneer JT-215A Digital audio timer in action.

just a note - this is why "logic decks" had the timer rec-off-play sliders. (look at 8m38s) in your clip.
thanks for yet another great video.

Not trying to be an arse, but since 1994 I could record to my computer an audio stream at any given time. The hard part was dealing with the payload of data. I had server grade backup tape machines. Later CD-R. Could never justify a standalone timer device connected to a recorder.

Whilst I didn't own this model I did have a number of timers. Panasonic and Technics made rack mounted versions so you could use the timer record setting on your tape deck.
The flick mechanism was used extensively in clock radios of the time. I used to see the Sony versions.
I needed a timer to turn on a transformer connected to a loud bell in the morning to wake me up, and many other people in the flats where I lived.
The flick mechanisms had a habit of becoming noisy after a few years as the motors and mechanisms wore so I was glad when the electronic versions came out.
Now shall I climb in my loft to see what happened to the two I owned.
Thanks for the review Matt.
