It looks like you have blobs of solder on the input capacitor to the regulator shorting the input and output of the regulator to ground. There is also a very large blob of solder on one wire shorting the regulator output to ground . The output capacitor also looks like it is inserted with reversed polarity. It would help if you posted the schematic with components numbered so we could say for example C1+ instead of input capacitor. Your soldering is so bad around the rectifier diodes that I can't see the tracks.

thank you sir

 

@ferdz Do you have a schematic rather than just the PCB layout. I see your PCB isn't the one in the document; you've left off the 10 leds and driver transistors. Did you make it yourself?

 

In posts #1 and #21 you have only posted a printed circuit layout which is NOT a schematic.

@ferdz

This below is a printed circuit layout…



Below is a schematic. Note this schematic is for most of the circuit implemented on the attached printed circuit layout above.



These are just examples. They were both used in a project of mine.

 

Spot the obvious mistakes.... (and I don't mean the numerous probable shorts)

LH side is rear of board mirrored to match front....

sir what is the correct position of that diode In4001 and the cap?

 

Why will you not answer questions asked by members ? (You have been asked a number of times for the schematic and you have not responded.
Irving's post #25 shows the positive (Red) and negative (black) paths to the regulator. Compare that with the output of the bridge rectifier.

Your big cap is OK, your small cap is reversed. Your diodes need to be swapped over left to right & vice versa. It's quite likely your 7805 is damaged but you won't know until you rectify the faults. All the other chips may be damaged; again you won't know until you sort it out.

Your copper tracks appear badly discoloured or are they coated with something? When you solder to them you must ensure they are shiny copper and tin them with some flux and solder so they are shiny metallic before trying to solder a component to them.

It is always good practice, especially for a beginner, to assemble just the power supply element and check that's working and producing the correct voltages at the right locations before physically assembling the remaining parts.
