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%!

Reverberation fails to resonate

In the second of two videos where I'm auditioning components for my HiFi I try out a Reverberation Amplifier. 

Always a niche HiFi component, the reverb box has intrigued me for a while. Why would people choose to spend money on a device that added reverb to pre-recorded music. This was something that I would have to try for myself to see if it earned a place in my audio system. Find out how I got on in the video below.

You can find HiFi reverb boxes on ebay

Actually that seems to be one of the simplest variants of such effects. Essentially it has a "digital loop of tape" inside and you can adjust the speed of it running and maybe it feeds back the output to the input. That gives you a rather crude echo-type reverb.

More advanced reverbs are now found on AV receivers. For example some Yamaha receivers will use them in their "Cinema DSP" modes. In "Mono Movie"-mode they will, for example, put your sound to the centre speaker, while putting a bit of reverb on the other channels.

You should be able to have the reverb unit display the color psyco effect by connecting for
example REC OUT from your amplifier to the LINE IN on the reverb unit
(or possible REC INPUT) eg just 2 RCA cables.
Then the colors should flash even though you are not listening through the unit. Eg just eye candy.... ;)

Two older devices that will actually enhance your listening and are a blast to play with are an Eventide Ultra Harmonizer and a Behringer DSP 9024. Perhaps give them a try in the future.

If you want to keep the blinking thing in your living room, I would guess that the mechanism to turn it on and off is fairly simple. There is probably a wire that goes to the reverberation on off switch which also lights up the display when it is on. So you could probably just find and connect that to a similar voltage power source inside the device and it will be on whenever the device is powered up.
