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 :

you said Joule Thief?

you said Joule Thief? you said Joule Thief? 

It’s a little wisp of a circuit that allows you to drive aPOWER  LED from a low voltage. Normally, if you want to light up a blue or white LED you need to provide it with 3 – 3.5 V, like from a 3 V lithium coin cell.

But the magic of JT is  a 1.5 V battery like a AA cell simply will work. 
Easy make  Joule Thief,  works like a charm. Not only does it work with a brand new battery, but it works until the battery is nearly dead– down to 0.3 V. 

That’s well below the point where your other toys will tell you the battery is dead, so it can steal every last joule of energy from the battery (hence the name).

how about a cellphone charger , yes it is doable , we are here to give you  a usable tested diagram .

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 padels 10Nox or 20 in Pack
