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%! 


Yi Dash-Cam Review

Over the last year, Xiaoyi's Yi action camera has turned out to be a very popular model due to its keen price and excellent image quality. So when the company announced their first dashcam, I instantly put in my order. That was back on New Year's day...there have been some delays with shipping, but it finally arrived a couple of weeks ago and I can demonstrate it to you now.

In the video below you can find out whether the Xiaoyi Car Camera can live up to the familiy name.

If you click your country below you can find the sellers of this camera on ebay. You may need to activate International Search in the left hand panel.

UPDATE: Now available with English language menus.

There is now a black model that is more discreet, as well as multiple menu language options.

Teac AI-501DA-S - Amp/DAC 

I try to make videos that don't date quickly - and that's why I rarely mention the price of the object being shown. This video is an exception, the Teac AI-501DA is a discountined product with the remaining stock currently being sold off at half price on Amazon. I can't see it being around for more than a few weeks at that price. I've put this video together quickly so you don't miss out on the opportunity to pick up one at a good discount.

In the brief time I had it available to test - it felt like a very well built and capable machine. If I was putting together a compact HiFi system then it would certainly be on my shortlist, for its looks alone if nothing else.

Video demonstration below.





Retro HiFi Two-in-One video

This video features two devices, The first is the Realistic APM-200 - an external add-on VU meter sold in the 1970s & 1980s through Radioshack and Tandy. The main subject of the video though is the Onkyo U30 - an RCA Switchbox/Pre-amp. 

I really don't see why an enterprising manufacturer couldn't bring back either one or both of these types of devices. If they were to go a step further and add in a DAC, then we'd really have an handy all-in-one HiFi component. Perhaps I've just given someone the idea for a Kickstarter.


Techmoan is now on Patreon

Techmoan can now be supported through donations on Patreon. If you are unsure as to what Patreon is, it's a way of paying for something that you can also get for free. It's akin to throwing a coin into a busker's hat, you don't have to do it, there's no obligation, it's merely a way of showing gratitude and providing financial support.

There's no hard sell here. My youtube videos and this site will remain free to all, however if you want to pay a visit to my Patreon page - it's here:


I'm tired of suckers talking smack about my K7s

Or in plain English - I'm fed up with cassettes getting a bad rap. Yes the technology has been superseded, but that's no reason to be dissing (there I go again) the best-selling pre-recorded music format of the 80s & 90s. To me it's akin to slagging off your her funeral. 

I made the video below to put the record (tape) straight. The cassette may have come and gone, but few people ever heard it at it's best. Before I made this video, I was one of those people. However rather than make up stories about how bad it was in an attempt to be hip and popular, I've made an effort to find out the truth about tapes. Watch the video below to see how I get on.

So saying cassettes were rubbish is the same as driving a Trabant and then saying cars are rubbish. Listening to cheap tapes on a dodgy stack system, or a Saisho/Matsui 'Walkman' was how most people remember them, but that's doing cassettes a massive disservice. 

I've got a few links below if you want to give cassettes a second chance. 

You can find all sorts of machines on ebay
If you are looking to buy the same model of machine I bought - the model is the Sony TC-S1 - this link will search for it on eBay UK 
However the TC-S1 is part of the Sony Scala system and some people list it under this - so this link will look for the Sony Scala on eBay UK 
Whatever eBay search you are doing - it's advisable to expand it to include the rest of Europe - the prices and condition are often better if you source a machine from Germany, Austria, the Netherlands etc.  
Don't just search for Dolby S - as often this spec is not mentioned in the title of an auction.
I buy blank Metal Tapes from Tapeline in the UK 

Here's a link to the video I mention at the end, about the Last Audio Cassette Factory

If my video was too basic for you - don't complain, just head over to TAPEHEADS.NET where you can get really technical about whatever tape related topic you want.

*Regarding the K7 in the article title - it's a slang abbreviation of Cassette used in a number of countries around the world - just pronounce the letter and number in French and you'll understand why. 


Yaqin SD-CD3 Tube Processor - add valves to any Hi-Fi

We're back in the world of audio today with one of the strange devices you can usually find in the back of a HiFi magazine. Alongside the adverts for isolation feet, electricity conditioners and oxygen free cable I spotted a device that promised to bring the 'richness of tubes' to any HiFi. However I didn't buy that device (the IFi Micro itube stage buffer), and I'd still love to test it out, but it did plant a seed in my head which ultimately resulted in me buying the Yaqin SD-CD3 that you can see tested below.

The Yaqin SD-CD3, can be found on Amazon US and UK


The fully-loaded Gitup Git2 Pro Camera - what more do you need?

I've reviewed many action cameras with each new model (usually) improving upon the last. However pretty much every camera I've tested has had an achilles heel, whether it was the lack of a mic input, poor exposure control, or general operational issues, it's often a case of 'close, but no cigar'.

Well I think the Git2 deserves that cigar, because I'm really struggling to find anything that it doesn't do. As far as these kinds of cameras go, it seems to tick the box for every feature you need and then throw in a few more besides.

If you are looking for a matchbox sized camera and the Git2 falls within your budget, I really can't think of anything that should prevent you from buying it. I suppose you might prefer to pay more for a camera with less features but labelled up with a brand name you are more familiar with...and if so then that's your prerogative, however I know which camera I'd buy.

Watch the video below to see the full review.

If you want to buy a Gitup Git2 Pro, I found the best deals are on ebay, so click your country below to see the current price that is available to you.

Here's something old - The Playtape

Before compact cassette, before 8-track...there was Playtape.

I like nothing better than trying out a piece of obscure technology for the first time. Opening up a BNIB (brand new in box) gadget from the past really can feel like taking a trip back in time.

Almost fifty years ago, a teenager somewhere in America will have opened up a box, taken out their Playtape machine and played their first tape. That teenager will be a pensioner now, and their tapes and machine long since gone. However the Playtape machine that they didn't buy, the one that got left in the store in 1967, stuck in a warehouse for almost half a century, frozen in time, sealed in styrofoam, finally gets it's chance to entertain... in the video below. 


The playtape format is largely forgotten and doesn't have a great online presence, however there are a few places you can find out more, including the always excellent Museum of Obsolete Media and Baja's Playtape page which also includes a comprehensive tapeography.

Playtapes can usually be bought from ebay and you can still find unopened tapes on there, some for over $100.

Recording inside and outside the car - with the Transcend DrivePro 520 Dashcam

Over the last few years I've been searching for a suitable camera for taxi drivers. They regularly get in touch asking me to recommend a camera that's able to record both the road and their passengers, day and night. I finally have an answer, and it's the Transcend DrivePro 520. Full video review below.

A 360º Appraisal of the Ricoh Theta S Camera

Since the introduction of the original 360º Theta Camera in 2013, the Ricoh engineers have continued to develop their two-lens spherical camera technology and now their latest model, the Theta S, is available in the UK.

You can see my full review below.


In the video I voice some disatisfaction with the apps and software that accompany the camera. I know that in many ways this is uncharted territory, however Ricoh have had over two years practice and to me the image management experience still feels very beta. The ecosystem surrounding the 360º Bublcam seemed a lot more user friendly. 

For example, the fact that Ricoh don't allow me to post full quality video clips over 11 seconds or batch-upload images seem like rookie errors....and the lack of a delayed shutter on a camera where you often need time to get out-of-shot is puzzling. The Bublcam has a delay shutter as standard. 


China Town - Spherical Image - RICOH THETA


However software and firmware can always be updated - if the actual technology that creates the 360º images didn't work well then things would be a lot more serious, but it does work, and it works flawlessly.

The next time I go on holiday, in addition to my main camera I will definitely be taking the Theta S along as well, and that's really the biggest accolade that I can give to any camera.

What a 10 Hour Music playlist looked like in 1992

In some ways 1992 doesn't feel all that long ago to me, but then in others it's a lifetime away. This is aptly demonstrated by the subject of this video. The Sony TC-C521 still feels like a cool piece of tech, interesting to watch, it looks smart and sounds great. The much maligned tape cassettes, to me still sound as good as I need my music to sound. I'm just as happy listening to a cassette as I am a lossless recording - for me it's the quality of the arrangement that counts rather than the medium it's on.

Where the march of progress is most notable though, is how we now take for granted the ease at which we can gather together individual music tracks and move them between different playback devices. As I mentioned in the video, I recently copied 15 hours of my favourite music onto my smartwatch, just for the heck of it. It would have taken me just a few more seconds to copy the same tracks to my smartphone or a portable music player. The most difficult and time consuming part of making a digital music playlist is selecting the tracks, things were a lot different in the analogue days as can be seen in the video below.


When putting this video together I came to the realisation that the art of playlist creation may soon become a thing of the past. The move from locally stored MP3s to streamed music means that the curation is now being done by someone else. Ready-made playlists of music that you should like are now offered up and are just a finger tap away.

Time marches on and inevitably hard drives full of MP3s will soon look as passé as a carousel of cassette tapes.

If you are interested in Cassette changers here's some other models I've found.The 1990 Pioneer 6 cassette changers, CT-M5R & CT-M6R, the 1980s Sony 10 cassette MTL-10, the 1970s 20 Cassette Panasonic RS296 and Philips N2401 6 cassette player.  Information on these and others can be found here.
