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


  1. Fasteners : 3 sizes 3mm//4mm length screw and nut pars : Buy a lot 
  2. 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 . 
  3.  A cheapo soldering to melt away plastic, A nail file to heat and cut plastic 
  4.  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 

Tips to get the  perfect drills :


Use a paper ,  lay on the final pcb  ,mark the posotions . 
 Stick with favicol to case , it is much easier This way.

  Its a physical labour intense task . The common cases DIY guys choose


  •  Tin cans _ very easy in so many online shops they are sold .
  •  Plastic switch boards cases - everywhere in INDIA can be procured
  • the die cast aluminium case :  they last lifetime , rugged , looks cool the aliexpress store is my favorite https://www.aliexpress.com/w/wholesale-effects-pedal-case.html

     You can see the case that is pre drilled just 900Rs , takes 20days to deliver, due to india customs .







Here are SE_LABS Guitar padel in making . It is a distortion with better opAMP .


Without getting too technical, it’s basically a “dual switch ” distortion that allows you to toggle between 2 different gain settings in one pedal—pretty useful if you want to dial in a crunchy lead sound then punch up the gain for a heavier metal play back . All told, I’ve been having a ton of fun with this one proto padel  and recommend checking it out. well not of a player I am but  for my masochistic exhaustiveness, I’m going to build a similar project by the fine fellas at runoffgroove.com called the Double D (both use the same chip for a similar dual channel idea…)  and run tests .

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 .

Why know about bitcoin ?
The digital money trade is steadily heading towards immersion in the North American and European markets. One of the significant drivers of the market has been opportunity from keeping money wallet from hidden taxes and easy to open and keep up a financial balance that is fast raising . The immature managing an account framework in Asia and African market, conversely, fundamentally higher development chances to digital money exchanging stages. While a considerable measure of digital money trade organizations done recent quarter on more immersed Western market, the push to promote bitcoins in Asia and Africa obviously after that wannacry event .
