cool reverb apart from switch spdt 'pop' issue

@quad:  not yet, awaiting pcb.

@quad:  not yet, awaiting pcb.

...which I will work on tonight

[Oatmeal]

What size enclosure do you think this will fit in? I think I'm gonna order a brick and try it.

[R O Tiree]

Just drilling to go, Rob, and trim the board to size. I might take a sickie tomorrow (feeling like poo) so I might be able to get it in the post in the afternoon. If not, Saturday morning.

[deadastronaut]

@mike: excellente' news.....i'll finish up my 1590b  etch design then..

stop skiving...

[R O Tiree]

OK, I skived... feeling pretty man-flu-ey, really. Ever noticed that significant others don't feel much sympathy for us when we're feeling icky? "I've got to go into town... you coming, or are you just going to waste the day?" etc, etc.

Anyway, the board's drilled and milled, so I'll pop it in the post Sat am.

Is there anything you need from my stash? 0.2" x 0.3" 1µF box cap with 0.2" lead-spacing, for example?

[R O Tiree]

PCB is now subject to the tender mercies of HM Royal Mail, 1st Class (not that that actually means it'll get there any quicker...)

I breadboarded this and thought it's design is a bit over my head.  I think it sounds really great.  Thanks for offering it up to the masses.  If you get a PCB Layout, please let me know.  I would love to etch it single side even if it's as big as a toaster

Will the whole thing fit into a 1590B?

[deadastronaut]

@mike:  nice one man, will probably get it monday morning then...brilliant!.

@gold/quad..

1590b hopefully..

[R O Tiree]

The PCB is 2.0" x 1.7" (5.08cm x 4.32cm) but the brick hangs off the side, adding another 1" or so, making it about 2.0" x 2.7" (5.08cm x 6.86cm).

Rob and I have tried to design it to fit into a 1590B (he doesn't do batteries - only 9VDC adaptors on his board).

If Rob's happy, I'm happy to put my PCB art out there - be aware that I used isolation routing, so we're talking traces of 15thou and 12thou clearance from the traces and pads to the GND plane.

[deadastronaut]

i'm very happy indeed!.....

nice one mike!.


@goldstache:  i have also done a diylc layout. i'll check it over and if its ok i'll post up the pdf's ok.

might be smaller than a toaster though... 

[deadastronaut]

ok, here ya go,here's my version,  i checked over the pdf's, (not as tidy as i would've liked ) , but i check the schematic against the layout and seems to checkout ok.

unverified, but looks ok to my eyes...

Here are the files for anyone who wishes to have a go at this little monkey...

Wooo Hooooo!  Thanks Everyone!  Can't wait to not have to hall out my reverb tank! 
Really Thankful. 
Your skills astound me! 

[deadastronaut]

ok, got the pcb from mike this morning, (very nice pro looking board it is too) populated it..




all works fine...

just a couple of notes;

brick was backwards, and feedback/damp pots, (i'm used to 3 2 1 from the back of a pot) ...but hey thats no issue at all really (just a heads up)..

works great, and bright switch works fine too....brilliant.

i just need to trim up the ribbon wire and brick pins then fit the brick to the board..done..

cheers mike!!!!... ...i'll etch up my box later and get this puppy boxed  


i made a 9 led vu meter...very tempted to fit this in now too....see how it goes..

[quad]

Thanks a lot for the schematic and the PCB R O Tiree & deadastronaut. Looking great! Can't wait to see the final result. I'm about to order a brick. Haven't yet made up my mind on which timing to get. Short, medium or long... 

[R O Tiree]

Oh... poo schoolboy error, sorry. I'm re-designing the board, then.

[R O Tiree]

OK, here are the new v1.3 files (I just knew I should have waited for a bug report from Rob...). If you downloaded the previous ones, you might as well delete them - they're wrong!

[deadastronaut]

no worries mike, its all working fine anyway..that was a dream to solder that pcb...quality job you did there man..  

anything you need doing just ask ok!

wow that was quick adjustment of the pcb too.


@quad: this layout is for the BTDR-2H....not sure if it would behave the same with the med/small....but hey it might.

...depends on your taste/style i guess.....or build 2
