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 Gakken WorldEye

This unusual device intrigued me so much, I just had to buy one and try it out for myself.  Watch the video below to learn more about what it does, then read the paragraphs below for a bit of behind the scenes info.

While I was putting this video together it began to occur to me that it probably wouldn’t be of interest to most of my subscribers.  I therefore kept the video brief, uploaded it youtube and moved onto making the next one. However when I released the video early on Patreon, the response was a lot more positive than I expected. A few people wanted to know more about some of the features I’d skirted over and Anders from offered to try to create some new videos for it. 

After he sent me over his new videos and they worked perfectly I returned to my video review, took it down and re-edited it to include an extra five minutes of demonstrations. In an unusual turn of events, the act of reviewing something has actually increased it’s ‘usefulness’.   So now if you do import a Worldeye you’ll have something else to play on it other than the original Japanese clips. 


You’ll be importing from Japan - so turn on international search in abay and you may also end up paying duties.

Prices vary choose a seller carefully as they are all offering the same device. 

New Videos For the Worldeye

The newly created videos for the Worldeye can be downloaded from here. These were all created by Anders Enger Jensen - who is also the talented musician behind the Retro cassette seen in a couple of recent videos. His website can be found here. 

I'd ask that you kindly only download the videos if you own a Worldeye as they don't display properly on a traditional screen.

I went to a female doctor for the first time yesterday. The first thing she said was "You must stop masturbating immediately!". I asked why. She said "Because I'm trying to examine you!"

It looks like the stand is flimsy enough that you could probably get away with rotating the device 90 degrees to pull it out and adjust it, rather than having to disconnect everything.

In the 1980s the MIT Media Lab experimented with a telepresence system that used plastic "faces" that they would project a video image of the remote person. They called it "Talking Heads." From what I understand it was a pretty convincing demo in that most people thought it was pretty creepy. I wonder if this thing could be adapted for that purpose?

May 17, 2017 | Unregistered CommenterReadyKilowatt

Fascinating, as always Mat!
I recently took some photos using an 8mm fisheye lens that has a 180 degree view - I wonder what they'd look like projected into the Worldeye? I can't decide whether they'd look relatively normal or doubly distorted.
Here's a Dropbox link in case you're tempted to try!

Greetings, I enjoyed the video and was very interested in this product. I promptly ordered one. I downloaded the files your friend made as well. Very cool gadget. I was wondering could you ask him to make a rotating deathstar loop?

Many thanks

Just received mine today and the remote doesn't work. I tried 3 new batteries and nothing. It only takes one right?

June 1, 2017 | Unregistered CommenterRobert israel

Yes it just takes the one battery. I've never figured out where you have to point the remote at - I think the receiver is somewhere inside the screen. All I can suggest is to try it in a different location in case something in the room is throwing out a load of IR...but that's very unlikely. Sorry I can't help any more.

- Good and interesting vid.
- It's a device waiting for a good use.
- Needs someone to make some good content that makes the best of it.
- I have seen the "Talking Heads" thing mentioned above it was at a historical visitor atraction somewhere - as you approached a display a blank head suddenly came alive and welcomed you and told you all about the scene - it was very good - can see how some would find it creepy.
- seeing the worldeye reminded me of the "Talking Heads" thing.

Anyone able to advise on PSU for this. Looking at buying one and seller says "Power plug is for Japan use. AC 100V 800W 50/60Hz for Japan The voltage for this electronic device is 100V and made for Japan usage ONLY. In order for you to use this device outside Japan where the voltage is higher than 100V such as 200V-240V. You are required to use a transformer to adjust the voltage to your local country. "

I'd rather just have a new UK PSU so anyone know the voltage.current and plug details please?

June 8, 2017 | Unregistered CommenterJames

My adaptor is multi-voltage, if I were you I'd wait until it arrives before you do anything.
