Vivo V7 phone Ya kasra !

Vivo V7 
Vivo Electronics Corp. is a phone brand based in Dongguan, Guangdong, China. It was founded in 2009. The company is another Chinese smartphone maker but this one spends more on dealer commission and IPL 

To make the markets flooded with choices , they sale too many models . 
Do you know vivo and OPPO are same cell companies . 
Avid indian buyer  gets confused . 

Vivo  tries to copy flagship product samsung/xiaomi  but it fails there are lots of segments 



But to market the  vivo guys have many many  online comparision of OPPO Vs VIVO 


1. Snapdragon 635 which heat phone very fast
2. Still screen resolution is low
3. Ram is low
4. No direct video call
5. Battery capacity low for that price 
6. Camera focal lens is poor
7. Camera pics are over processed in software , look unnatural

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
