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%! 


Harman Kardon Aura Airplay Speaker

I bought a refurbished Airplay speaker I'm very happy with. Here's my video about it.

I bought it from the Harman Kardon Outlet Store where they sell refurbished models. It's much like the Apple Refurb store where the items look brand new...but even better as these products come in standard packaging.

For people elsewhere in the world - you could always try your luck on ebay.



A great small Dashcam (with a screen) - Vantrue N1

Small dashcams with an LCD screen are few and far between. The Mini-08 range is one of the most common, but suffers from reliability issues. So much so, that I refuse to review any more due to the high failure rates.

So it's refreshing to see a new mini camera that works well. It isn't overloaded with features like GPS or Lane Departure Warning, it's just a good solid sensible little camera that comes with an 18 month warranty.

Of course only time will tell how reliable the N1 proves to be, but I have a lot more confidence in this camera than I would with yet another Mini 080*.

FIRMWARE 14th May 2016

Here is the firmware (I take no responsibility if you brick your camera with this). 
Only use this if the Time and date Stamp is not appearing on your videos and your existing firmware is OLDER than 14th May 2016. There is no need to install it if your camera is already working perfectly.

The file is here -
1) Copy bin file to memory card
2) Put card in camera
4) Turn camera off
5) Take card out of camera
6) Delete Bin File (empty the Trash on your computer to make sure it's gone)
7) Put card back in camera
8) Check the firmware number in the menu to confirm that it has updated to the 14th May 2016 Firmware.





Retro Tech: The 3M Cantata 700 Background Music Machine

Another delve into unusual audio technology from the past. In this video I take a look at the 3M Cantata 700, a format that boasts the largest music cartridge ever made.

If you think 8-track tapes were a bit bulky, wait until you see this. 

If you want, you can CLICK HERE to download a 1hr MP3 of Music recorded from one of the Cantata tapes (I forget which one). This is all I am able to capture at the moment as the machine has now taken to chewing up tapes and making horrible rattling noises.


You can power a Dashcam via your OBD port - But perhaps you shouldn't


Watch the short video below to see this demonstrated.

Make sure you read the youtube comments as a number of people there explain why powering something from the OBD port is a bad idea...and then a few more people say that it should be fine, there's no problem.

It's really your decision as I just don't know enough about auto electrics to categorically confirm either camp is correct. 

You can obtain OBD to USB power leads from the links below:


Gramovox Vertical Record Player Review

The Floating Record Vertical Turntable was a successful Kickstarter campaign.The idea behind it was to make a quality turntable that takes up less shelf space, looks great and sounds good. Did they deliver - watch the video below to find out.

VCD vs UHD and what's the big deal with UHD anyway

First a (ludricrous) 'competition' between the oldest and the newest video formats on which you can buy current releases. It's VCD vs UHD Blu-ray

Secondly if you think the new UHD Blu-ray format and UHD TV's are all about the resolution....think again.


VCDs were purchased from YesAsia 




Retro-tech. That time when HD came on VHS

Perhaps it's a good thing that D-Theater never made it to the UK, the spelling of the name would have been an insurmountable issue. 

This might be the first retro-tech product I've featured in a video where I can remember seeing one in action back when it was new. Whenever a TV manufacturer wanted to show off their new HDTVs at an AV show, they needed HD Video to show on them. Before Blu-ray or HD-DVD came to market if you peered around the back of a TV at a show in the UK you could usually either spot a PC or occasionally an imported D-Theater machine providing the HD signal.

Getting a working D-Theater machine delivered to the UK has taken a lot more time (and money) than I anticipated when I set out to make this video last year. I'm really glad, and quite relieved, that I can finally present it to you here today.

The supplimentary video showing NYC in 1993 in HD has really blown-up on the internet in the last couple of days.. and it keeps getting re-posted. A shame that I couldn't monitise it, but after all it is not my video and the soundtrack is copyright. The real star is the unknown cameraman who captured such great shots with the early HD video equipment back in 1993.

For those wondering what HD video camera tech existed in 1993 -  there are a few options, but it's likely that this footage was shot with a HDVS camera- perhaps a Sony SONY HDC-500 attached to a HDV-10 portable recorder which recorded on UniHi 3/4" tape. 




Here's another tip about wires

In 2011 when I was installing my AV Receiver, I picked up a camera and made a quick video showing how UK speaker connections have a cap that can be removed to allow the insertion of banana plugs.

That video still receives regular comments of thanks from people who found it useful.

So recently when I found myself needing to install a long Component wire to my 4K LG TV (for an upcoming retro-tech video player review) I discovered that a four pole headphone extension cable can be used as a quick and easily substitute to a chunky component cable.

Its a bit more niche than the first video, but people with old game consoles and new TVs might find this tip useful too.


The New 2016 Square Nixie Watch

Back in 2010 I bought a Nixie watch from Cathode Corner. This was something that I had wanted to own for a couple of years, but it was also a considerable amount of money for me to spend, and really far more than I could sensibly afford at the time. 

In hindsight though, buying that watch turned out to be one of the best investments I've made. The (amateurish) video I made about it has now been seen by well over a million people and has helped to introduce many new subscribers to the channel.

The idea I could buy something that I couldn't really afford to feature in a video and hope to pay for it over time using the ad revenue has shaped the way the channel has been run ever since. My slightly rash decision to buy that watch late one night has by now paid dividends, and also created a connection between myself and the watch creator, David from Cathode Corner. 

So when the time came for David to present his new square Nixie Watch to the world, he turned to me to make a new video, and you can see this below. As six years have elapsed between the two videos I'd like to think that this one is considerably less amateurish (and it's now in 4K).

It is moments like this that really make all the effort worthwhile.

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 


Time to Equalize Some Graphics

I'll be making an upgrade to my HiFi setup in a few weeks which involves shifting quite a few things around. Before this happens I wanted to audition a couple of new (old) components to see if they deserve a place in the new setup.

In this video I look at a sophisticated and surprisingly useful graphic equalizer, the Akai EA-A7.

I realised after finishing the video, I didn't show the rear panel, so here it is.

If you want your own Graphic Equalizer, here are a few ebay options (click to perform a search).

Akai EA-A7 (good luck finding one)  Technics   PilePro    Rockville

Oh, by the way I've deliberately used the American spelling of Equalizer because this is how it it written on the device itself. Akai never made a Graphic Equaliser.
