Graphene semiconductors mark new start
Life, James Hein, Published on 17/01/2024
» We have just started 2024 and there are already exciting announcements. The clever people at Georgia Tech in Atlanta have built the first scalable semiconductor using a graphene base. Graphene, a wonder product, is not a scalable semiconductor on its own, so they bonded silicon carbide, or what we call carborundum, to a layer of graphene creating the necessary bandgap to have a working switch. A switch means binary and from there they can make wafers like those currently used in the chip manufacturing process to make CPUs and other devices.

Will fold-out phones start a new revolution?
Life, James Hein, Published on 27/02/2019
» Lower cost Google phones will be arriving this year. There will be mid-range offerings somewhere in the 4,700-22,000 baht range and another below that as a low-range product. The target is emerging markets that are fairly well saturated with other brands, both Korean and Chinese. The Google Pixel is the high-end product and is supposed to have the best camera, for now, but they are not cheap. The new range will round out the lower end of the market.

The WiGig revolution slowly gains traction
Life, James Hein, Published on 24/02/2016
» Some time back I wrote that we would soon be seeing 100Gbps on our wireless data connections. The Japanese have claimed this speed using a new transmitter operating in the 275-305GHz range. This is close to standard fibre speeds using Wi-Fi and uses a multichannel technology to achieve it. Current Wi-Fi technology operates around the 5GHz band and at 60GHz for the so-called WiGig system. The higher the operating frequency the faster the data transmission and the expectation here is for terabits per second, or to put it another way, very fast. To do this they will need to extend the technology to an even higher frequency range.

New 'bendy' phones rock (literally)
Life, James Hein, Published on 19/02/2014
» I’ve mentioned this before, “bendy” phones do not sit well in a front pocket or in dashboard stands and while they might curve nicely in one’s back pocket, this also means they are easy to forget and potentially sit on. Yes, the so called “bendy” phones, which are really just fixed curved phones, are starting to appear with the LG G-Flex the first to hit the public’s pockets — and it rocks. Yes, literally. If you put it on its back, it rocks up and down if you give it a little push. On a more serious note, it’s quite a good phone with a decent screen, great battery life and power under the hood.

3D Doctor Who a literal headache
Life, James Hein, Published on 04/12/2013
» It is interesting how much we take modern technology for granted these days. We read stories of people who believe their in-car GPS units over common sense and have ended up on dead- end streets, in rivers, lakes and the sides of house _ in one case up a tree. The younger generation believe Google and Wikipedia over Grandpa, who was actually there. People create fantasy words in which they spend hours, but real-life meetings are sometimes avoided.

Can tablets, 3D move beyond niche markets?
Database, James Hein, Published on 28/07/2010
» Forget the iPad for a moment and consider that the tablet revolution started a decade or so ago and never went anywhere. Today tablet machines occupy a fairly small niche market. People just don't want to interface with a machine using only their fingers on a touch screen. Once the novelty wears off it is back to the notebook or PC computers.

Of 3D, iPads and other fads
