the future unwraps on your hand !

Cell phones are many the  screen is one constraint that has not been addressed . The flip phones has  dual screen but all hated the begels . 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 substra

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. Related: Elon Musk is expecting to arrive spaceships on Mars in 2022 "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 tak

Home for everyone ! DIY enclosure for circuits

We at SELABs yet at proto stage , some protos have  been finalized but leaving the circuit naked and casing are two things .  The casing is 30% extra task .  Remember projects without box gets damaged or lost .  You are an Engineer not a craftman so dont go buying all tools , dremels needed but cost Rs 4000 to 8000. For starters they are not a must .  To make the DIY enclosure for circuits you will need Fasteners : 3 sizes 3mm//4mm length screw and nut pars : Buy a lot  Drill and file and hecksaw : these are tools of trade . drill are there in tolexo dot com for 600Rs Round and flat file needed too .   A cheapo soldering to melt away plastic, A nail file to heat and cut plastic   Acrylic cutters : in case making from acrylic , I recommend a acrylic cutter 100RS or so in amazon    Needed knobs and sockets to be bought in aliexpress , it is the  better way    dc sockets : 20Nos    plugs : 20    audio sockets and jack 20pair    Knobs 50   3pdt _ for guitar pa

Mobile towers impact on human body

- In 1994  , two cell towers were  installed on a five story apartment building in London. Residents complained of many health problems in the following years. Un expectedly Seven of them were diagnosed with cancer.This is marked as " cellphone tower of doom "

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 power

Battery-less Mobile Technology..the future of cellphone

Here is  a cellphone that  harvests the  ambient energy . What is the Ambient energy? We have a blanket of RF energy surrounded by so many cell towers Harvesting energy from the environment,is the way to go for future cellphones  But the cell phones cant be created just by an antenna and signals from it , researchers at University of Washington have their own way to  do that digital communication . “We’ve built what we believe is the first functioning cellphone that consumes almost zero power,” said co-author  Shyam Gollakota Converting analog signals that to have corresponding  data that a phone can understand consumes so much energy that it’s been impossible to design a phone that can rely on ambient power sources. They have developed a special way that   takes advantage of tiny vibrations in a phone’s microphone or speaker that occur when a person is talking into a phone. To transmit speech, the phone uses vibrations from the device’s microphone to encode speech

BULBMAN , no kerosene

    Our country is amazing  , one way moon mission , smart phones   on the other side there are billions are using  age old kerosene lamps .   Have you ever thought why  ? The Chinese lights have not  been able to replace the traditional lamp .The vendors taking china lamp are eating poor people's money . Considering to the fact that engineers only want to work in big companies no one tries to reach the poor the main problem a usable light .There are solar light but no one is reliable , of lower cost . #makeinAssam #diy #gaming #electronics There are main problems in making a nice chargeable lamp .The lead battery lasts just 150 cycle and the case is another big cost incurred by the poor .   We at SELABS have developed the bulb that takes USB or small solar and has a life of 4 years    On top cost is too low . Syska etc are seiing such bulb in 600Rs(GST RATE included)  , they charge via mains and use      cheapo battery .  We have a quali

Why suddenly two cameras ?  Smartphone cameras are improving  slowly nowadays, I will say not as fast as the marketing pic shown   however they are bound to follow  hard physical limits .
