Delta Pulse Problem

Hi Everyone,

I have constructed the DP1 and its not working.. The issue that I have is I am not getting any sound from it... I have made my own PCB using the sonsor.lay file which was posted here.

I have found that the BC546 transistor has been inversed on this PCB and correctly soldered the components.... does anyone had the similar problem and found the solution???? If yes please help me...

Hi KT315,

You should write what you are modified, checking separete components is not easy,
btw i don't recomand you to use sprint layot for drawing PCB, it's wery poor cad software,
i used it and now i am not satisfied with it.
Try to use diptrace its wery good software easy to use and much bether than sprint layot.
I recomand it to all...

Recommends everybody else. :-)
I observed the developments. The Iranian kid's modifications and it they were over here I assured an opportunity that the frequency, the dumping resistors on the motherboard on his basis can be made change in let him be allowed to be. I modified the trussings. A-A, B-B I was looking for a road on the motherboard for the electrons.

Maybe anybody has did a schematic in OrCAD or P-CAD? would be greatly appreciated if you share it.

all the best

noticed there is free section of D10 (U10 in my schematic attached). IMO it may be used for auto-reset on turn-on.

Good idea, KT315

Hello Apocalypto
It's hard to help from here.
I can only say that the TL062 is not power device. Its power consumption is very low so not to take temperature.
Check the PCB and compare with the scheme, it is likely that there is any short circuit between the tracks, use a magnifying glass. Check the value and the correct installation of the nearby component.
Replace the TL062, may be damaged.

Hi KT315
maybe a silly question, but have you made a fully 100% working delta pulse ?
