Help with EasyEDA ground pour

[neiltheseal]

Hi everyone.

I'm trying my hand ad making my own pcb in EasyEDA but seem to have encountered a problem.

I have made a couple previously following a video tutorial (not printed as yet) and these allowed me to turn off GND nets and just do a copper pour.

On this green ringer I am putting together it seems that GND isn't turning up at all so I can't do this. In fact it seems to be the case that 9v and GND are connected somehow on the scematic.

Have I done something wrong here or is this just a quirk of the green ringer?

When I update the schematic to pcb i am given the option to check nets, but no issues were found here.

I suppose if I can't do a ground pour I can just manually connect ground together.

I am very green at this and have yet to order a pcb to be printed myself. I have put together 3 gerbers for pcbs and not encountered the issue above. I made a big muff, blues breaker and one knob fuzz and these all seem to have worked. Although as shipping is about $26 I'm trying to send a bunch of pcbs to be printed at once rather than pay that much shipping for each.

It looks like your 9v and gnd are connected? I'm not sure where, but I'd double check for that.

That’s where your 9V and GND are connected.

Also shouldn’t D2 be the same type of diode as D1?

This is your issue. The 9v and the ground are supposed to be connected to the resistors, not the diodes. The diodes connect to the next transistor stage.

I drew it a little differently to make it make more sense. I hate the way the schematics for the green ringer are usually drawn. There is a voltage divider biasing the output on each side of that transistor before it his the diodes going into the output buffer.

Thanks for this. That does make more sense. I’ll try this.

Thanks. Good to know I’m not going crazy.

Thanks so much for this.

Yes it is. Just a typo but thanks for picking it up.

I tried it this way and it worked straight away. Thanks again.
