[deadastronaut]

How many did your order? Are they the same board on the upper left hand corner?

[deadastronaut]

hi armando, yep the same.. i ordered up 10, but you get 11, result.

i'll populate one to verify as soon as i get time...should be cool though.

pukka quality, and nice traditional green

Finally got mine finished. The "L" modules were unavailable, so I used an "M". It sounds great, thanks for a superb design.

How do you post photos?

Rob,

This project was a lot of fun and I'm glad you're happy with the boards.  Thanks for letting me in on the fun!

Well, I'm not the best photographer, but this is a little tease of how the boards look populated.

This is my first etched enclosure and I still need to work out the kinks, but I wasn't going to trash the enclosure because of a few pits.  Gives it character, right?

Anyway, this is how she looks.

Cheers,
George

How do you post photos?

You need a photo host website to store your photos (photobucket and many others). Once you upload your photos, copy the direct URLs for them. Hit the photo icon above the posting window here in the forum and paste each URL between the image commands. It's easier than it sounds.   Your post should look something like this, except with square brackets [ ].

You can see an example by going to any post that has a photo and clicking "Quote".

This really looks great George. It looks like a fantastic layout.
BTW, Steve at Small Bear has the long reverb modules back
In stock.

hi george, man that looks lovely and neat inside...no more spaghetti yay!..  

the etch is fine man, you should've seen my first attempts..they either got painted and turned into other projects , or i flipped the box over and re tried it...

either way i used them..

i'll pop a board as soon as i get a chance...

i got my bricks from musikding in germany btw they were the cheapest i could find for UK/europe post etc..


@cozy: i got your message man about a 1590a    but cant see pics...  try dropbox.

Wow, that looks a lot nicer than my pcb

[Cozybuilder]

Thank you Jdansti for the photo instructions. Here is proof of my lunacy


Main board



Main & daughter boards



Jacks, switch, LED, regulator, daughterboard and plug installed



Complete gut shot- its all there



With apologies for my clearly underwhelming artistic abilities.

you nutter..i'm always amazed at the lengths you micro 1590a'ers   go to

[samhay]

Cozybuilder - that is astonishing, especially seeing as you used perf! I like the use of the Millennium bypass daughter board and the header pins.
Any chance you could share the layout?

Rob / George - nice boards.

[Cozybuilder]

Here is the pencil drawing of the layout that I worked from. Both sides of the board are used in fitting components and wiring. C1 is 100μF

Amazing!

Now... take my money and make me one 

[Jdansti]

@Cozy- that's simply amazing!!!

How are you crazy people fitting this into a 1590a!
I need a hell of a lot of room, hence I used an old pie tin. You know one of those grim chicken and mushroom ones in the blue tin. After eating the contents (an unpleasant task) I sanded it down and due to the shape I couldn't help but make a homage to Robs whole space theme. I say homage, but I've actually just done a bit of a rip off of his design for the flying saucer reverb. I've also added colour changing LEDs (probably a bad decision as a get a little background noise buzz as they change, but its only faint so I've decided to stick with style over substance)
So here it is




Anyway enough about pretty lights and pie tins. This pedal also sounds awesome! I've built a few different pedals before and each time have had to do loads of fault finding after, so to make things a little harder for myself I thought I would try and etch my own pcb for the first time. I used 1:1:1 mix of Hydrochloric acid (32%), hydrogen peroxide (40%) and water and just drew the design on the copper with a permanent marker. a few seconds and it was done! and to my utter surprise after populating the PCB it worked first time!!! and it sounds great. Thanks for sharing this Rob. I'd been looking for a worth while DIY reverb and this really is worth the while!

[deadastronaut]

Brilliant, absolutely love the abduction graphic...very cool. Cheers . Rob. 

[therealfindo]

I'm serious @Cozybuilder - this reverb sits on my small board always on, so a 1590A version would be suh-weet!

[Jdansti]

Nice one 9aul, and you hit on some of Rob's favorite themes- space, aliens, and LEDs!  Maybe even grim chicken and mushrooms!
