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%!

'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.

Great video, Mat. It does beggar the question -Why? Why would Seiko put their name to this? Why would any 'executive' buy it? Why would ANYONE?

I came here to see if you have any reviews of the recent SJCAM offerings. They seem to have released a bunch of new cameras lately. I'd be particularly interested in seeing a review of the M20 and forthcoming SJ6 Legend and SJ360 cameras. - I'm especially eager to find out how well the new wireless remote works (as I currently don't like having to tie my iPhone up tethered to the SJ4000s Wifi connection in order to just hit the record button remotely) - I am often needing to use my iPhone for other functions at the same time, such as using the metronome app or to play music, whilst I am recording. - I currently use the SJ4000 to record myself practicing drums, but I hate having to keep climbing from behind my drum set over to the camera every time I stop/start a take. It can really interrupt my flow, and is also a hassle because I have to climb up to the ceiling where my camera is mounted, to start/stop or operate the camera's controls in order to retrieve the footage. It would good to know how well the external mic function works too, as I'd like to feed a stereo input to the camera from my audio interface, as I have a bunch of pro-audio mics already set up on my kit, so if I can feed a stereo drum mix into the camera - it saves me loads of time afterwards having to splice separate audio and video feeds together in Final Cut Pro.

I really doubt it was made by Seiko Instruments. Its lack of quality shows this probably was made in China.

being a retro tech amateur historian myself i found this exciting in that the disc shaped magnetic sheet was probably a bad batch of floppy disc material that wasnt good enough for data . and the question occurs to me why didnt anyone try to make an audio format with floppies. yes i know it would have "flopped" but so many have been tried and failed in the past. i mean data was recorded on square vinyl like what was in the old magazines and then used to transfer to cassette to run a computer. why not .I guess ive witnessed too much tech go by

Seiko Talking Egg! Funny and quite charming. A reminder of an era that didn't always take itself too seriously!
