This is my Klon Buffer that I built.
I designed the PCB and had it fabricated by dorkbot (FTW).
I got a real geeky rush when my first boards arrived in the post; it was like being a kid at christmas or something ha ha!
This buffer circuit seems to have become the standard beginners project for people doing their own PCB layouts here at Madbean.
Its built in a heavy duty enclosure (pre powdercoated grey) with no swithces or anything as its always on.
I have also uploaded a pic of my SHO layout that I have built up; it sounds good so I will be boxing it up soon.

They both look great! I really wanna get into doing this..what's your recommendation?
Magic, you should star with a Muff of course!
It seems like everyone's into it now. Dorkbot is revolutionizing the DIY Pedal thing.

I totally agree with this Magic... You really have a great, marketable design with that shrine fuzz. I know I really want one. On the side I can help you get a layout together if you have a schematic.
Great job Raul, I really like that gray powder coat, looks so Pete Cornish 8)
Yep dorkbot was certainly a revellation to me.
I personally do not have the time/inclination to start etching!
I have already ordered three more boards (Catalinbread Formula No.5, Soulsonic Folkdriver and ROG Omega Boost) with dorkbot and have a few more designs ready to go (MS20 Filter with LFO etc.).
bigmuffwizz; go look on gaussmarkov's diy site at all his eagle tutorials. Follow each one in order and you should be on your way.
It really is addictive doing layouts though so beware!
A lot of my PCB questions have been answered on this forum too so don't hesitate to ask. :)
Thanks for the compliments Paul (I posted before I read your reply)!
Magic: I would be happy to have a go at a Layout for this Fuzz design of yours too if you have a schematic.
Really great job :)
I have read through that tutorial, it really helped me with getting going. My first attempt was a Timmy which didn't really go all too well. The schematic part is easy but when I got to the board layout it was just too overwhelming. I'm kinda bummed that Gauss Markov doesn't cover that part at all except ground pour. He does say laying out is an art which could very well be my explanation! I should probably start with something easy like the rest of you, even though a Muff is my obvious goal.
It's just the basic muff schem, but modified in a few ways to my liking and apparently others also. You all are encouraging me greatly to try again. And it's great to know if I can't get it done, I got some folks to hold my hand :)
Plus out of respect for Brian, I'm gonna have to stop using Gruntboxes even though I like the layout soo much!
I learned by copying. Madbean projects are good to copy actually.
Starting with a fuzz or buffer or boost is a good idea too. Those are super easy to learn with.
Now I'm up to Delays with modulation and tap tempo...

I would start again with a simple circuit (like the klon buffer and SHO ;) ) and see how it goes.
One tip I have picked up is to set the bottom layer as your ground plane before you start routing any components. This erradicates a lot of air wires which can make things look more daunting than it really is.
There aren't really any layout rules or methods as far as Im aware though.
Once you have one layout under your belt then it is just a case of working your way up in complexity I guess.
The good thing about dorkbot is that your paying for two layers which makes things a bit easier in terms of layout(rather than etching with single layer).
I agree. Two layers is quite good as far as layouts go. However, I would recommend that anyone getting into doing layouts learn how to do things on one layer for a while. The reason is that layouts are more challenging that way, and you need to be much more creative in how you route things and lay things out. I've learnt a lot of my tricks and habits from doing one layer layouts, and they've certainly been very helpful as I've expanded to doing two layers. Ground plane is also very helpful.

I agreed with everything said here. I try to complete everything I do in one layer first, then move to double. It's more challenging and usually ends up neater and more compact in double layer. I also have a layout to share with all of the etchers :)
Tidy work man, that pcb looks awesome! :)
Cheers Dude!
I really enjoyed putting these together.
I can't wait till my next boards arrive.
Plus I have loads of Madbean to build as well; so many projects so little time :)

I'm intrigued Jim! Wonder what it could be...

:) I said that in response as to why I start making my layouts single layer only first go around. Although I do have a couple of layouts I am working on :) Another thing I did when I started with layouts is download all of the gaussmarkov files, he includes all of his eagle files with his projects. It is much easier to try and manipulate something that is already layed out then start fresh, it will get you in the groove :)
This is really impressive! Well done man, super tidy too.
Cheers Pete,
When I have built my next batch of boards (Fo No 5, Omega Boost and FolkDriver) and have confirmed they all work I will upload the PCB layouts on the forum for everyone to use.
The next lot are mainly single layer so they should be good for etching.

Definetly looking forward to seeing them, you've really sprung mine and other's alike's interest in eagle.
For that i thank you - i've got the schematic side down, just need to do some PCB layout learning. I'd love to do a small series of PCB mountable boost and 1 knob effects - something you could just chuck into any effect enclosure easly on a spare drilled hole.
Cheers sc,
There is LOADS of information/layouts on this forum to do with eagle.
Madbean even posted an OSP Tubescreamer Project which you can load up and play around with.
There is also an Eagle FAQ thread somewhere here with a lot of usefull tips (pad sizes, clearances etc).
Boosts are very suitable for small boards; the SHO I have done is less than an inch square so will easily fit on the back of a pot.
Let us all know how you get on :)
