Many  features of note8 that pushes IPHONE 8 tobe a failure. In india the iphone8 sales and bookings registered too low, they blame it on iphone x. But reality is lack of innovation . The basic nerve of all new  smartphone buyers rests on innovation . The  cell markets are flooded with better players in android  arena. The samsung note 8 is a stunning example . Following are some new innovations that note8 has come up with which makes apple device a thing of the past :  Infinite display : as they promised a stunning looking screen innocation .  camera innovation : 12MP cameras on the back that both feature Optical Image Stabilisation.  Additionally, the two sensors also feature Samsung’s Dual Pixel technology and Phase Detection Autofocus. App innovation : pair of apps can be launched together,This feature opens both the apps in split screen mode, allowing you to do two tasks faster than ever before. The deXdock : The dock caters full sc...

An inverter is a daily used household device ..to create an un-interrupted on 220V AC or 110V AC (the AC voltage depends upon the line voltage of the specific nation) supply to the gadget associated as alternate power to main  socket.The inverter gives consistent AC voltage at its peak hours with auto turning on when the AC mains control supply isn't accessible. The modern inverters work very silently and there are very few indications .  The SUKAM , luminous ,Microtek etc companies have dominated this segment .  Every year crore profit is taken out from ASSAM just because we do not have engineers who will join hands to create a makeINaxom inverter prduct line . 

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.

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 vi...

    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 .

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 . We all are aware of style conscious customers they will not go for thick phone . Modern cells have  constraints of  camera area a device that’s 7mm thick, and phone companies are looking for alternative means to keep improving.  Approx in june 2016, LG and Huawei have led the new dual camera technology  new Android flagships , may be apple was buzy perfecting .  === দুটা কেমেৰা কিয় ?    কাৰন ফনৰ ৭মিমি জেগাত হাই প্ৰফাইল লেনচ চিচতেম , better sensor দিব নোৱাৰি    ।তাৰ বাবেই দুৱেল কেমেৰাৰে বহুগুন   উন্নত ইমাজ দিব পাৰিছে ।   এই দুইকেমেৰাই দিয়া ইমেজক Hardware processingত একলগ কৰি...

So, I think you could use a zener-transistor circuit like this for your purpose.Adapting to 5v solar panel is  super easy .

 Here we are starting  innovation revolution  in assam !   Innovation always relates to small small know how that add up to impact milllion times .   Can we make a solar security system, that runs forever ?   yes we can , but most systems need a 'battery replacement'   and  we always have to change battery after 200cycle   also many systems need wiring ! who wants to wire up house with 6 pairs of wire for 6sensors  So most viable item for a lifetime charge discharge is super capacitor . As name suuggested the supercaps are huge capacity capacitors like 1000times more but have same size as normal caps .   The circuit   Circuit ::   Its a current limited SOLAr circuit ? the 15ohm 1watter is a limiter like 180mA current   other wise circuit make dead short if the supercap is there  , that way the solar panel do not  burn out .   A ...
