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%!

Cassettes: Filler video

The problem with working on ten things at once is that sometimes I find that none of them are ready. The last time I went a week without putting out a video someone kindly told the subscribers I was dead. so to avoid dying again - I've assembled a short video featuring three things connected around the theme of cassettes.

Normal service will be resumed as soon as possible. Techmoan apologises for this delay and any inconvenience caused.

great deck! surprised that it plays it - would have expected it to stop (spools not turning, thinks it end of tape)
also nice to see classic hiphop albums brought out on tape new (a (C)2016 on a cassette is cool)

i see DAT in the background of your hobbyroom, wonder if you ever did a clip on that?

as always, thanks for making the clips and the great fun you give me watching it.

I remember some sort of endless cassette system was used in the first early Panasonic answering machines.
They were dual cassette tape based systems and the endless tape was for the out gong message and second cassette tape was for recording the incoming record message.
I think they had some system, perhaps a piece of foil to stop the cassette and reset the outgoing message.
It was a long time ago so excuse me if I am wrong.

I enjoyd it non the less, mister moan.

here's another filler-suggestion: could you tell something about the flexidisc?

(I found out some stuff that dissapointed me; once I was sort-of ready to have my own made I found out the company had closed just three months before.. hence I tought: "that might be nice info to share with more tech geeks" but due to having a kid and having another coming up I never got to the making-tubevids-myself-plan that I had brewing for sometime.

here's some oil for the machine:

but maybe you'd found out about that one already...

anyway: loads of props and 1.000.000 thanx for doing your thing, mister moan! much apprecietion from the netherlands
