Review: MECO ELEVERDE High-Pressure Electric Air Duster Blower

This was sent in for review and it intrigued me enough to give it a good test. I should say that I've always struggled just a little with the idea of blowing air around to clean things up, as opposed to using a decent handheld vacuum cleaner to suck dust. After all, surely blowing dust from something just distributes it around the room? I'll illustrate this with one of the promotional photos from this very product, showing the cleaning of a dust-filled PC fan: Now, I don't doubt for a second that blasting high pressure air at this gunked up PC fan would blow the dust right away. The problem is that the very same dust is then all over the inside of the PC and, probably, the room! It's common sense that, where possible, suction should be used, to neatly collect dust in one place, where it can be safely emptied.  However. Suction alone can't get everywhere . The typical use for a tradition compressed air can would be to blast out crumbs from a computer keyboard or with

How to fix Blink XT2 Camera 'Thumbnail failed' error!

Update - Jan 2023: Amazon/Blink just changed the interface in their app - so things may have moved slightly in the UI! The Blink XT2 cameras are great - a trivial way to keep an eye on a loved one (in my case an aged parent) without wires or complex DIY hassle. Just set a camera or two up on your Wifi and you can keep an eye on them from across the world.  And all is fine, generally, I tap to take a photo or video if my dad isn't answering the phone, to check where he is and whether he's OK. Yes, there's motion detection available, but I usually have this off as when he's well he'll move around and keep triggering images and videos, which then drain the batteries too quickly. (I do have motion detection on my own house's security cameras, outdoors) But recently I had the strangest error: 'Thumbnail failed' on one of the cameras and it persisted for days.  Now, I live 150 miles away and so Blink's suggestion of 'take the batteries out and put them

Review: Zecti LED Ring Light

(Disclaimer: this was sent in for review by Choetech, which I presume is related to the Zecti brand) I have to confess that I'm not the target market for this ring light, for two reasons: I wear glasses, so you get horrible reflections of the LED in the lenses! (see frame grab below!) I don't use the internal phone holder - partly because of reason '1', and partly because it's not terribly rigid and is easy to knock slightly out of position, ruining framing. My use case is when filming myself with the rear camera of a phone, for video podcasting. On a gloomy day, even by a window, a little extra light from the shadow side of my face is most welcome. So why not give this a try? In reality the frame is very, very plastic (fair enough, as it is plastic), made worse by the sickly pink colour. The idea is clearly for 20 year old females to shoot selfie videos or pics - so perhaps I shouldn't mark the product down for this! (Backing up my theory, the product comes wi
