Help with EAGLE CMoy design, please =)

Out pin is the virtual gnd. Com goes to V- In goes to V+. The center pin of the TLE should be connected to V- not gnd.

Layout is starting to look better. The side of the board by the output jack is significantly better than your last layout. I like how you've got all the resistor s lined up so the vgnd trace runs in a line. See if you can sort out the resistors on the other side. Sometimes just rotating a part or maybe swapping two left to right will help a lot.

The autorouter isn't helping things. Look at the path from R2R to capR. Try ripping up a few traces and routing them by hand. You can also have Eagle auto a single net.

Keep at it. You are getting better.

Jashatdot, you're doing wonderfully.

Have'nt checked this thread for a while, then I checked your last diagram and board design, and that looks promising.
Question is why you chose to use only one power cap, when it looks like you have plenty of space? It needed to be at least 25V rating when you use two 9V batteries. And I think almost all OPamp, even faster ones, may not have problem with this amp design. Even if there is a problem, a couple ceramic cap usually can take care of it. Any specific reason for limiting sort of OPamps?

Keep up with good work.

Here are my Project & Library Files

ExpressPCB offers their Standard service with Double-sided boards, Tin/Lead plating, Perimeter routed to shape. I calculated for 10 boards to be about $80 USD + shipping, and 20 boards to be $104 USD.

I fixed my TLE library & CMoy design. I got the traces are 16 mill now (I would like 24 or 32 mill, but I'll need to edit it ALOT for that to work)


EDIT:

I just saw that this is my 1000th post!!! W00T!

 

[AndrewFischer]

Olixmex is going to be around $45 but you will get as many boards as they will fit in 6.3"x3.9". Edit-- I don't think Olimex won't route your odd shaped board.

Check out batchPCB for the prototype.

And congrats on post 1000.

 

[mr-awesome]

here is my design from the files you provided, i moved some stuff a lil bit, to make the lines a little neater.

i tried putting attachments on , but i cant ill make a megaupload file for them in a min.

here is a link to the file
here
just type in the code, and hit enter, it will download to a zip folder named new folder
here are the pics

the traces are .024 one step up from the starter one
the schematic is the same as the one josh provided

 

[Joshatdot]

I hope this will be final layout..heh

Now with 32mill Traces!
and Smaller Board!

Board is 1.30in x 1.70in

 

[mr-awesome]

nice, looks neater than mine. im looking to order like 3-4 boards, any suggestions on what company could do an order for like 30$.

I doubt you'll find any PCB maker to be under $50 USD. AndrewFisher said that Olixmex will do as many that will fit on a 6.3"x3.9" board for ~$45. I am going to check them out.

 

[mr-awesome]

im gonna spend some time on google looking for something, if i find something that does small orders ill post.

check the bottom of this page, they have a big list of pcb manufacturers

here

this one looks like it would work for what i want, http://www.pcbex.com/

josh can i get your new updated files so i can see if they will work with this website.

If you do use Olimex be sure to check your drill sizes. Olimex will charge you $1.30 for every drill that isn't 0.7 mm, 0.9 mm, 1.0 mm, 1.1 mm , 1.3 mm, 1.5 mm, 2.1 mm, 3.3 mm. You also have to make sure the silk screen is at least 10mils wide or they will charge you to fix it.

Layout keeps getting better.

There is something wrong with the switch on your pot... notice how Eagle wants to put a trace between the pins? Either a schematic problem or a problem with the part in the library.

Also, as far as Olimex goes, there is a ulp file available on cadsoft that fixes these. I of course did not run this before I sent my boards out to them and paid around $12 in extra charges for drill sizes.

I also took a fairly quick stab at this... used a ground plane on top with 3 traces routed on top with vias. These would be easy even for home etching... pop a reistor lead in each of the vias and solder both sides. The only things I didn't deal with were the ground pins on the pot and jacks, which would require something similar if home etched.

OMG I didn't even notice that! and now Fixed

I dont know how to make the top GND only, AND make sure the other routes work on my board with out it even more messed up.

I just noticed that in EAGLE's ERC tool I got LOTS of warnings

......I tried to manually route the traces...there's something wrong witbh the POT SWITCH...its effing up the routes.
