The Internet of Things (IoT) with ESP8266 - Part 1

The embedded designs have been gaining rapid acceptance in  smart homes . The world is a connected place now a days .
 The physical data is plugged to net via The Internet of Things (IoT) .

Physical data access embedded with electronics, software, sensors, and connectivity enabling data exchang The trend is , a little networked board is attached to a thing,or a item that has  special data . The  thing can be  lightbulbs, toasters, refrigerators, flower pots, watches, fans, planes, trains, automobiles, or anything else around you .


 So to get you the data on your nice HD screen of mobile we need a brain and a connection . So most IOT devices have these and associated memory and IO pins .
 Usually they are designed to fill a gap in the device i.e.control the thing according to USER and monitor . That can be a home based system and a office system or traffic related .
 The IOT is limitless  and most seeked after device domain among developers .

 Today we look at a  very powerful yet low cost IO  based on th ESP8266 (presently ESP8266EX) which  is a chip with which manufacturers ,make module . Specs are as follows ::

 It 32-bit processor controller core and runs at 80 MHz (or overclocked to 160 MHz).
 It has a 64 KB boot ROM, 64 KB instruction RAM and 96 KB data RAM.

 IO interface with general-purpose input/output (16 GPIO), Inter-Integrated Circuit (I²C),
analog-to-digital conversion (10-bit ADC),
Serial Peripheral Interface (SPI),
 I²S interfaces with DMA (sharing pins with GPIO),
UART (on dedicated pins, plus a transmit-only UART can be enabled on GPIO2), and pulse-width modulation (PWM).

 This is a most needed spec , and in Rs 500 with shipping its is catching embedded developers
 The core resource site is :

The flex OLEDS :: 
As the availability of consumer OLED-display products continues to expand, so have research efforts in future trends of the low-power, light-weight, and superior-viewing-enabled OLED technology. Bendable, rugged, and eventu-ally roll-out flexible OLED (FOLED) displays are actively being developed by numerous university and industry groups, taking advantage of the demonstrated flexibility of both small moleculel and polymer2 OLEDs. The key chal-lenges to be overcome for the realization of flexible active-matrix OLED (AMOLED) displays can be classified into three main categories: substrate/backplane development, OLED development, and OLED display lifetime. Substrate and backplane development are interrelated in that the backplane technology chosen will depend on the limitations (thermal, chemical, etc.) of the flexible substrate. …

8 unbelievable things you never knew about Thinnest TV ever

Every one wants a thin TV , so tvs getting thinner . 
Can it be bodyless , just a paper sticker yet perform very well . 
 Not the LG guys gone insane 4K in just 2.5MM . Whooah . 
 makes me think it can be as sensitive as a flex glass .

SpaceX ElonMask , is building up inter-globe-travel : Newyork to Mumbai in 30Minutes

Elon Musk predicts rockets will one day have the capacity to fly individuals from New York to Shanghai in only 39 minutes.

Musk's organization, SpaceX, is building up a colossal shuttle to colonize Mars. It could likewise be utilized substantially nearer to home.

Talking at a space meeting in Australia on Friday, Musk said the organization had investigated applying the innovation to zooming individuals to better places on Earth in madly quick circumstances.


"The outcomes are very intriguing," he said as a video demonstrated a recreation of individuals boarding a rocket in New York that launched into space and afterward returned to arrive in Shanghai.

"The  most interesting thing about going to space is there's no contact, so once you're out of the air ... it'll be smooth as silk, there's no climate," Musk said.

Most voyages between focuses on this planet will take under 30 min…
