Can any one please do me a favor by converting this schematic into PCB design Answered

As i don't know how to make a PCB design. So please help me out.? and the the software i used to make the schematic didn't had a photocell symbol so used an LED symbol and also the relay i used is the simple 12V relay. I would be glad if someone really help me out on this one. and if one does please send its layout to my email: abdullahazam.747@gmail.com


i made a pcb design it looks like this can u tell if its ok?


i made this circuit on breadboard, i want 100 pieces of it for which PCB is required. whereas i used EXPRESSPCB but i'm unable to make it on it. i made this on EXPRESSSCH its easy to use but the other one i feel hard to use the PCB one........

(Moving this to top level)

Printed circuits are great for mass manufacturing but they aren't always the best answer for homebrew. For a one-off you may want to skip the PCB, and just use perfboard and point-to-point wiring.

Wire-wrap construction can help speed that up, slit-and-wrap especially so but even manually stripped wirewrap can be faster than soldering individual components. You do have to think a bit more about routing the wires to keep it from becoming unmaintainable spaghetti, admittedly; using a hot glue gun to tack down some of the longer runs can be helpful.

On simpler circuits, even dead-bug construction may be worth considering. (Turn the DIP upside down and just connect other components directly to its pins and to each other using their leads and a minimum of additional wire., with everything hanging in mid-air and being kept from shorting out mostly by luck and hope rather than being held safely in place by the perfboard.) Very ugly, unmaintainable, but sometimes Good Enough for something that's essentially a throw-away..

If you're making more than a few, sure, invest in laying out a PCB. If you want it pretty, invest in laying out a PCB. If you're working with surface-mount components, or if there are places where the spacing is critical to control crosstalk, go with the PCB. But if you're only making one, using DIPS and other non-surface-mount parts, and it isn't running at radio frequencies, the PCB may be a non-productive distraction.

(In fact -- if you enter "wire wrap circuit" or "breadboard circuit" or "perfboard circuit" in the Instructables search box, you'll find some descriptions of these alternatives.)

I found a free program called EXPRESSPCB.com that is "easy" to use that will allow you to draw a schematic, then draw the PCB, then click to send it to the company and they will make 3 boards for about 60 dollars. I tried several other software programs such as EAGLE and could not figure out how to use them. You might give EXPRESS PCB software a try.

You should know there are those of us who make our living doing PCB layouts.

You will need to know what relay and PCM pin locations to the millimeter including width and length ??
How is the motor wire attached ( solder, screws etc ) what diameter hole ??
What is the spacing of the photo cell leads ??
Do you want to put a resistor in series with the photocell ??
Is the battery 9V and clip on to PCB do you want a power switch ??
What is the value of the and style of C ??
Are you going to use an 8 pin socket or solder the 555 in ??
Is the speaker on the PCB ??
How many watts are the 100 ohm resistors 1 and 2 ??
Single side PCB .060 thick isO.K. ??
I presume the batt Plus is connected to the wiper on the relay ??
And ground goes to IC-C-batt-speaker-relay and motor ??
You are not using the diischarge pin 7 of the 555 ???
CV pin 5 could use a .01uF to ground ??
What are your desired PCB dimensions ?? ( This affects Rupees )
I don't plan to layout for you, but weather you do it or someone else
these questions need to be addressed.


It's a bit much asking someone to lay out a board for you.  If someone does take you up on the offer, they would need more info on the relays and a few other parts whos PCB footprints are not obvious from the schematic alone.

Here is a tool for laying out small boards of moderate to low complexity:


It's free and very intuitive to use.  If you get into it, you can use your creation to order boards from them.  You can also generate outputs that can be used with toner transfer and UV exposure methods by exporting their results to a bit map a printing them out.
