hello! I meant that I will send a PM to all who have responded here and/or sent me a PM just to confirm totals. but as always I will order some extra in case...

PCB has couple little things to fix but pretty much ready to go!

I have tallied up your names and made a list of qty. so get ready.

now to bed but tomorrow, I start sending for confirmation.

so here's a look at where it's at- pretty dense Smile

I have taken to standing some parts up vertically as I tweak to make space, starting to think I should go 4.2"x3" [will still fit between Euro/frac rails as well as behind a Buchla sized panel.] instead of the 4"x3" i was shooting for.. would make for some more comfortable spacing esp around the corners where its REALLY tight

any objections to this? I can't really see any downside myself really. it would be the same size as a TWF board.

yeah, I think it will work for everyone. for those making Serge like panels, it's not exact, but I imagine they have to be very resourceful to squeeze all those DIY boards behind them anyways [except Ken's]

More room is better, but do what you have to do...I'll be putting it behind a 5U panel anyway.

ok, done in 4.2" x 3". and it's STILL tight!! wow. this is the densest board I have done to be sure. can't wait till the 'smd revolution' in diy Wink

anyways- there are SOME smd. just bypass caps on the bottom of the board, 4-5 if I can squeeze them in, 0805 size. they really are easy to install I promise..

also- I was not able to line all the ins/outs up into neat little rows- you have a few stray pads here and there. but the wiring will be 20X easier than wiring 2 of the previous boards together.

more later/ PS if anyone wants to go in on protoboards with me, PM me please [this means you can build yours right away and let me know how it goes Wink

] if we do 5 pcs, they'll come out to around $25-$30 ea. with the shipping..

OK well we're very close to ordering time now!! Smile

Great news, and the layout looks great! I just started doing layouts, and so far haven't used my own schematics yet, just done some redesigns of others floating around. I haven't done anything that dense yet. I've been trying to get better at my routings though to get sizes down like that. Nice!

thanks! yes I used to be scared to mash components togther too tight, but Ive learned to do it working in euro stuff Smile

oh also it helps to have them profeesionally made, over home etching in that regard Smile

Hi Topp, did you see my post in the other thread? Just thought you may have missed it since you replied here after I posted there.

Hello
I'd like to know more about shipping overseas:
is it 7$ per board?
or is it 7$ for any number of boards?

Thanks!!!
