HOW TO MAKE A VARIABLE POWER SUPPLY
In this video I have made a variable power supply using an adjustable voltage regulator LM 317 and a power transistor to increase its output current . I have tried to make this video as easy as it could be and used common components. I Hope it would be helpful
1- 1X LM 317
2- 1X D1047 TRANSISTOR
3- 1X BD139 TRANSISTOR
4- 1X 5 K OHM VERIABLE RESISTOR
5- 1X 10 K OHM VERIABLE RESISTOR
6- 1X 4.7 K OHM RESISTOR
7- 1X 4.7 OHM 10 WATT RESISTOR
8- 1X 220 OHM RESISTORS
9- 1X LED
10- 2X2 PIN TERMINAL BLOCKS
11- HEAT SINKS
12- 1X VERO BOARD
13- SOME WIRES
+Kiyani's Lab Thanks a lot sir. Here I am trying to design a symmetric power supply circuit. Please correct whether something is wrong or not, sir. This is the link : https://drive.google.com/open?id=1U3PRHgx3GmdnEVA-pJavQCIMN8iPwr72
Brother, Maine ye circuit battery charging ke liye banaya hai.circuit think kaam kar raha hai per current output battery lagane ke baad kewal 200ma Max hi as raha hai. Jabaki have 300ma per battery ko charge karana hai. Kya Karen? Meri battery 11.5 v Tak discharge hai. Maine input smps 24 v 3A see Diya hai .Please help.
I made this circuit it was well running but d1047 transistor got heated up very soon
Today I used my micro motor and it got burned with fumes
Please help me what to do Bhai
And how will I check my transformer amp
Trading stocks typically have the lowest fees on eToro, which is one reason why I recommend you stick to this market when starting out.
All trades charge both a spread and daily rollover fees.
It really comes down to individual trading strategies and preference. But to give you an idea, I tend to hold on to stocks for a minimum of 6 months and all other trades tend to have an average duration of about two-three weeks.
A final word on over-trading.
This is a point that I want to expand on a little more, specifically in relation to copying other traders. Below is a screenshot of my equity chart over six months. The red line shows the number of people copying me.

The same holds true for the stock market in general.
