The low-cost mini satellites bringing mobile to the world

Sky and Space Global's nano-satellites 

Large chunks of the planet are still of out of reach of mobile phone signals - billions are still without access to digital communications. But this could change thanks to shrinking satellite sizes and costs.
Lower-cost, space-based mobile phone services will soon be a reality thanks to one firm's fleet of nano-satellites that will bounce your voice or text signal from one spacecraft to the next and finally down to the person you're calling.
"People were thinking of using nano-satellites for Earth imagery but nobody had thought of using them for voice or text communications," says Israeli former fighter pilot Meir Moalem, the chief executive of Sky and Space Global (SAS).
"We were the first."

His firm is aiming to offer customers mobile phone connections via a constellation of 200 shoebox-sized satellites weighing just 10kg (22lb) each.

Dragon Touch Vision 3 4K WiFi Action Camera Review

Image
I ordered this camera for general filming, I wanted a small but capable camera like the GoPro that could be used for lots of purposes - without having to worry about shock or water damage. This camera was a much cheaper alternative to the GoPro. The camera comes with the standard range of mounts and accessories, but some notable ones were that it came with a carrying case (many don't), a spare battery and a remote for photos/videos. I liked that there was a spare battery as when recording at 1080p these Action Cameras only typically last for about 1.5 hours of video, so many cameras don't come with a second battery when I think it's a must-have I was a bit disappointed that at 4K 30fps some frames were dropped, although this may be because I was using an older 4GB card that wasn't fast enough, I'll have to retry 4K video later on with a faster card.  What I found much better was 1080p 60fps recording, this was crystal clear and so smooth! For action shots, you wa...

Samsung Q65Q8FN Review

Image
The QLED series from Samsung builds on the Premium UHD series by adding a wider color gamut via Quantum Dot film and Quantum Dot color. It has excellent black levels and contrast and will capture the intended increased brightness and color of HDR content. This years model focuses more on an anti-reflective screen combined with better contrast through the new Q Contrast Plus technology. Has 240 motion rate. Differences between the Q7 and Q8 QLED TVs One of the key differences between the two series is the inclusion of the high end Ultra Black Panel in the Q8. Ultra Black Elite Panel:  Samsung is marketing this panel feature which is included only in the Q8 and Q9 QLEDs for those of us that do not adjust room light conditions when watching TV. This technology built in the Ultra Black panel increases brightness while decreasing glare by using micro dots on the surface of the panel to help redirect light from surroundings that would otherwise cause glare on the screen. The ot...

Alien Skin Exposure X3 review

Image
This review is based on use of Exposure X3 and a beta version of Exposure X3 Complete Workflow Update for Mac. Introduction We’ve reached the point with image editing software that most basic features are covered. Correcting for exposure, saturation, and other settings are the expected baseline, which means applications need something more to differentiate themselves. Some, like Skylum’s Luminar or Serif’s Affinity Photo (see Review: Affinity Photo 1.5.2 for desktop), are competing on price, along with the fact that they don’t require subscription plans. Add to the mix Alien Skin Software’s Exposure X3. It’s competitive on price—$149 on its own, or $199 for a bundle that includes a couple of the company’s utilities, with no subscription—but it also includes several unique features that demonstrate the company is willing to tailor the software experience to how its customers use the product. Differentiation in organizing Like Adobe’s Lightroom family of products, Expo...
