Moore’s law states that the number of transistors doubles every two years. Rachel Courtland from IEEE Spectrum explained the sharp turn of Moore’s law in 2021.
Chip manufactures will switch to another way of boosting the density in the chip by having multilayer chips using vertical geometry, and we’ve already seen the 3D concept in silicon chips like 3D NAND Flash. According to 2015 roadmap released by International Technology Roadmap for Semiconductors (ITRS), by 2021, shrinking the dimensions of transistors in microprocessors will not be desired economically by chip makers, although the report of 2014 predicted that the physical dimensions would continue to shrink until at least 2028.
According to the article, the spirit of Moore’s Law could still there, where some changes in the technologies will still lead to pack more transistors in a given area.
Rachel also mentioned that first international Rebooting Computing conference will be held in October this year 2016. It’s “Other ITRS participants are expected to continue on with a new roadmapping effort under a new name” Rachel said.
This project is a solution to power up most of devices or projects requiring dual (+/-) adjustable power supply. The circuit is based on LM317 positive and LM337 negative voltage regulators. LM3X7 series of adjustable 3 terminal regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V DC output range. On board TO220 Package with heat sink can handle maximum load current. Board provided with two on board preset to adjust the voltage.

A.Qadry @ Intelligent Minds tipped us with their latest project, a PCB prototyping machine. They are going to crowdfund the project soon so if you are find it cool you can follow them on their facebook page.
There are mainly two ways in talking about manufacturing, if you are going for a mass production by sure you will use photo-resist dry-films or you can use CNC engraving, Ink- transfer or even 3-D printing during prototyping but in this very first phase you need a fast & easy to use method to produce your prototypes and test your idea without expensive equipment, so that’s why we introduce this affordable machine to the market.
The creative idea we applied in Projecta is we cover the PCB board with any available metallic marker and the machine engraves the ink layer to produce a very high resolution image as resulted in photo-resist dry-films. We are going to a crowdfunding campaign for the mass production and wait your support!
Outfitted with a 2-A, 28-V power switch, the LT8335 2-MHz step-up DC/DC converter from Linear Technology operates from an input of 3 V to 25 V, suitable for applications with input sources ranging from a single-cell lithium-ion battery to automotive inputs.
The LT®8335 is a current mode DC/DC converter capable of generating either positive or negative output voltages using a single feedback pin. It can be configured as a boost, SEPIC or inverting converter consuming as low as 6μA of quiescent current. Low ripple Burst Mode operation maintains high efficiency down to very low output currents while keeping the output ripple below 15mV in a typical application. The internally compensated current mode architecture results in stable operation over a wide range of input and output voltages. Integrated soft-start and frequency foldback functions are included to control inductor current during start-up. The 2MHz operation combined with the small 8-lead DFN package, enables low cost, area efficient solutions.

A team of scientists at the Kavli Institute of Nanoscience at Delft University has achieved what may represent a limit in information storage density by creating a memory in which a single bit is represented by a single atom. By Graham Prophet @ edn-europe.com:
Specifically, the team created a 1 kByte memory array where each bit is represented by the (physical) position of one single chlorine atom. This equates to 500 Terabits per square inch (Tbpsi), 500 times better than the best commercial hard disk currently available. The team, led by the Institute’s Sander Otte, reported their work in Nature Nanotechnology on Monday July 18, 2016.
