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%!

The Giant ready-made LED Music Visualiser 

I like to bag a bargain as much as the next person....but occasionally I'll discover something I like that is only available from one place and seems likely to be discontinued at any moment. At times like this, there is really only one choice, pay up, or miss out. 

On this occasion after months of deliberating about the considerable cost, I decided I had to pay up...and acquired what I believe to be the largest ready made LED music visualiser currently available. 
Once it arrived, I wasn't sure what to do with it...but after a few weeks I decided it would be employed as an interesting object to have in the background whenever I was doing sections to the camera. 
After it appeared in two videos I received a lot of enthusiastic enquiries about the visualiser, most people asking me to make a video about it and show where it can be purchased. It has certainly caught people's attention, however I suspect that the positive comments are going to stop abruptly once people have seen
the video below. 
Now if you are in the market for a giant ready-made LED visualiser, and are prepared to pay for it....the only place I've seen this for sale is on here for the details. Expect to pay import duties on top of the final price. 
If you want to see the video about the smaller cheaper LED panel that I reviewed a couple of years here. It is important to remember that this smaller display doesn't have a microphone gets the sound via a 3.5mm stereo mini-jack input and also has a 3.5mm output, so it can be inserted between a source and the speaker. The small display can be purchased here.

Hi Mat, great video review - love the LED visualiser, love your humour as well.

Pricey - indeed, looks great fun though.

As always thanks for listening.

Thanks, the design certainly looks a bit like a homebrew system which you said and which it's probably are....
I was really stuck on LED's in the late 70's, I build some displays with EPROM patterns etc but they were expensive, had low output and a display like this would have drawn around 100W I'm sure.

I have noticed thie display in some of your prevoius videos, so I thought it may pop up soon!

Also love your "average reader" skit! :))))))

Also noticed you put a Phase Linear device under it, can't make it out though....

I went straight from here to googling a Raspberry Pi version to display on my TV. Imagine this on a 50" plasma. mmm. Couldn't find anything.

That's a bit disappointing, I was expecting there would be quite a few options...I'd like to try something similar myself. If anyone has any details of Raspberry Pi visualisers, please post them below.

How long have you been wanting to put a "spit take" in one of your videos?

Looks great. Inspired by your earlier graphic EQ review I purchased an L3D cube - it has a microphone and one of the 4 programs it comes with is a graphic music visualizer - because there is a depth of 8 levels to the cube you see how the music is changing through time which adds something great to the whole effect.
