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.

UK & US LINKS & PRICES BELOW

RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)

 

U3 CARD (For 4K cameras)

 

 

SPECIAL DASHCAM CARDS

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 dashcams...here'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%!

1986 in your pocket

Here’s a quick video about a forgotten gadget from the eighties. It’s a personal stereo with a built-in television. The idea of being able to carry this in a pocket was pretty cool back in 1986…but as you can see in the video, it did come with a few compromises.

I don't think there is anything wrong with your video sender's audio. This pocket tv set just happens not to be an UK model, thus using some other tv system than I.

If your video senders vision/sound carrier separation could be tuned, you should get audio. While system I had sound subcarrier at +5.9996 MHz, most West European countries had audio on +5.5 MHz (systems B and G) and East European countries on +6.5 MHz (systems D and K).

French had their own system L, where both vision and audio modulation are totally incompatible with rest of the Europe.

Some of the older DVB set top boxes had rf modulators that could be configured for a different tv standards. Perhaps re-purposing such an old set top box as video sender could be easier than re-tuning the video sender's audio subcarrier.

I had a mirror viewed Casio black and white pocket lcd television in the mid 1980's. It was quite useless, though. Resolution of the lcd screen was too low for subtitling to be readable. It was a real battery hog, too. But sure it still was a nice novelty item back then.

Based on that the UHF band starts at channel 14 and not 21, this set is likely for North American market. In that case the sound carrier of the video sender should be tuned to +4.5 MHz from vision carrier.

It's amazing that something so obviously flawed was put into production and onto the market. I wonder who the target market was - middle-aged gadget nerds or people who actually wanted to watch tv?

This is a great video post, it's so nice to reminisce at how technology has developed. Using a video blog to do it shows just how far digital technology has come recently and how much more accessible and simpler it is to use, as well as it's increasing popularity. A real embracing of trends!

I had my grandfather's Sinclair Microvision - hailed as the smallest TV IN THE WORLD!!!
If was quite cool, and multi-channel - See http://www.hampshirepictures.co.uk/retrokit/sinclair/images/mtv1-2.jpg

I had it hooked up to a ZX81, in a caravan, and it was the ONLY time I met the Minotaur in the maze game I was playing!
Finally sold it on eBay a number of years ago, with the imminent demise of the analogue TV signal.

My grandfather bought it to watch the cricket (BBC2) while on the Bench (He was a high court judge...)
Cricket on the BBC - yes this was a while ago!
