My journey from that Musical bell to embedded , audiosystems and SELABS

Okey ! No more long long posts i will convey this as  bullet points

 Me  At school :

 A science explorer , as mother was serving as lecturer in physics  she brought that curiosity to my mind  to experiment and so mind is formulated

while in class 7 we were on a trip  in rajasthan and my pocket video game fell down .. the loved toy of the schoolboy and the  world of circuits have welcomed me . Initially I was deeply moved by sunibarmans book

Engineering and beyond

  1.  projects , audio deck , others projects i used to do 
  2. critical ideas tested  LASER IO system and Powerline data transmitter .. felt myself capabble .. The power line unit used 22khz , a emergency light ferrite xforemr to inject  data as modulated frequency and PLL to detect .  Well it used to print junk char every 3 words or so and was fun built 
  3. made a Auto of casste deck : play songs , the deck cuts off 220V when cassate is over fun and fun 
The steps to EFY articles and Embedded days
in 2002 i have shifted to DELHI where my  EFY (electronics for you ) articles were accepted . became author , slowly i jumped to IT career and started reseaching AUDIO systems

The career path took me to banglore worked with INTEL , NETAPP , STmicroelectronics
On my spare time I was  making good audio DIY parallely indian audio forum hifivision i was a regular DIY guy .

in 2014 december met with accident and i was on bed and "sohoj electronics" started realizing life is short and we have to do remarkable work atleast on some field .

Now daily spare time i am devoting to full fill a dream of ELECTROINICS INDUSTRY IN ASSAM
!SELABS is the start of a big change ... i am sure we few can lead the way and billlions will follow.

2017 i have created first ASSAMSE circuits and tech   channel on youtube .
you can search it with "SOHOJE"  on youtube .

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
