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.

CLASS 10 UHS-1 CARDS (For HD 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%!

Retro-tech - The RCA CED Videodisc

Due to popular demand, I've made a video all about the RCA Videodisc system.

This was intended to be a quick and simple look at an obsolete technology, but somewhere during the course of the four problem-filled months that it took to put this video together, it went off the rails and ended up as a half hour video documenting man's struggle against machine(s).

It's like the youtube gadget-review version of Fitzcarraldo.

Some useful links:

CED Magic - The Website for everything about CED. Includes a full catalogue of every disc released.

The Full Electron microscope video on the Applied Science Channel can be seen here on youtube.

If you are interested in buying a CED player or discs on ebay - here are links for the US and the UK.

If you buy an old Hitachi player you'll need to replace those two rubber belts shown in the video. These can be purchased in the UK from CPC Farnell - here's the link

I remember seeing one of these being demonstrated in the local Hi-Fi shop back in the early 80's. I remember liking the look of the disk caddies Years later I found a tatty looking machine and a stack of disks at a radio rally. I would have given it a punt but the seller wanted a lot of money! Having seen your video I'm sort of glad I didn't. These machines look like they can be very troublesome! Great video and as always, very informative. Grat to see some working examples!
