Be careful, very long post ahead.......
When I recently decided to take stock of what I had laying around, pcb-wise, I had a bit of a freak-out: a stack of bare pcb's almost 4 inches high, and too much half finished ones to mention...... So I decided to start a ridiculous project to actually turn some of these in working, usable pedals. The past 2 weeks have been about finishing up some pedals that were near completion (JMK's Vibe and Standard Fuzz, RAH/Thunderpuss combo, and some more in the works), but bigger measures are in order, so here it is:
Project "I"....... For "Insanity"!
Project "I" will contain the following basics:
- 14 pcb's (maybe 15...)
- 4 enclosure
- 10 3PDT stomps
- 6 toggles
- 34 knobs
- 12 LED's
- 10 ¼" jacks and 4 9V jacks
It's going to be a four-part stash buster, and I'm going to use this thread to keep you all posted on how I'm doing. I'm suspecting some issues along the road as well, so there might be the occasional cry for help......
Here's the breakdown:
Part 1: AquaTwins
(http://imageshack.com/a/img89/508/r07c.png)
An Aquaboy Deluxe and an Aquaboy 2012 in one enclosure. This will use up my entire stash of MN3005's, and after this I won't buy any more. This box will give me a lot of different analogue delay options, from short slapback to longer, modulated delays. And a lot more....... I'm expecting some pretty serious (clock)noise issues with this, so there's going to be loads of shielded wire and maybe a grounded, metal separator between the two pcb's. But just imagine running one into the other! Maybe I should add a switch to change the order?
Part 2: Űberplex
(http://imageshack.com/a/img202/7104/s1zh.png)
More delay madness: Multiplex with switchable modulation on both delay lines, and external Ramp and Release controls. I love my standard Multiplex, and now I want more!! I'm not expecting too much problems with this one, but it's the only one in the bunch that needs all pcb's populated.... Fun!!!
Part 3: JamBox
(http://imageshack.com/a/img841/8612/y03v.png)
Been planning something like this for ages, but never got around to it: what do you bring to jam sessions when your playing through someone else's amp and want to travel light? In my case, it would be a box with a booster, an overdrive, a distortion and some sort of modulation. So this is going to have a Thunderpuss, an Egghead, a Dist+ and a Smoothie. To make my own life just a bit easier, the Thunderpuss will be switchable between being first or last in the chain, Egghead and Dist+ will get switchable diodes and there's going to be a loop to insert some more Fx. Any tips on where in the order I should place the loop are very much appreciated....
Part 4: GrindBox

This is going to be a gift for one of my best friends, the bass player from my band. First a Faultline, running on 18V via a Roadrage. After that, a 1776 Suckerpunch built to Bass Fuzz specs with a Schoontoon clean blend board added to it. I bet he's going to run it flat out , though...... All the caps are socketed on this, so if he doesn't like it, I can swap 'm and use this monster myself!
As you can see above, the first step was to model all of these in 3D to make sure it would all fit. Here's a family portret of the insides.

Next up is going to be ordering the remaining parts and enclosures, that's going to happen this weekend. I plan to post my progress regularly here, with some nice pics to go with it. Thanks for reading this, it was quite a stretch!!
Paul
Wow! This is insanity at its best! Can't wait to see the finished products. I have been meaning to build a travel pedal as well. Your inspiring me to get in it!
BTW how did you generate the 3D models? Brilliant!
The 3D models are created with Autocad 2013. It's not the best or easiest program for this kind of work, but it's what I know and have. Normally I do my layouts flat, tape'm to the box and drill, but I've been wanting to do this for some time, and this seemed like the right project to start ;D
Paul
Wow. This is completely insane (in a great way!). Great job on the 3D modeling, that is just plain awesome. It is great that you are finishing up half-built projects as well, I certainly need to do that myself.
I love the idea of all of the pedals but the "grab n' go" box for jam sessions really got my attention. I think the only thing extra that would make it super awesome would be putting a delay/reverb at the end of the chain that can be switched inline with the rest or switched to act with seperate 1/4" in/out jacks for an amp's FX loop.
Yikes, you've got some work ahead of you!
Sounds EPIC!!!
Josh
You HAVE to do a demo of the dual analog delay. Or you could demo all the pedals at once !!
This is something I want to see :)
Stoked to see those 2 delay projects, serious badassery ahead. 8)
Kickass! I built a travel pedal for a friend, and now I have one in the works for myself. It's really a neat idea, and I'm stoked about your delays.
Thanks for the encouragement guys! My wife suggested putting a time limit on this to challenge myself, but I don't think that's a very smart thing to do..... ;) I'll keep you all posted, and when the whole thing is done, demo's will be made. I'm in the process of getting some stuff I borrowed set up to make some better demo's, and that will be done waaaaaaaay before any of these are finished ;D
Paul
What a monumental project! I envy your dual Aquaboys, very cool idea.
Quick update: drilling templates are done, parts are ordered and should be in before the weekend, as I ordered through a Dutch supplier: http://www.newtone-online.nl/catalog/index.php (http://www.newtone-online.nl/catalog/index.php)
Just after I finished payment, I realised I forgot to include the knobs >:( but that gives me the opportunity to re-think the color/knob choices over the holidays. Still plenty to do before I'm ready for them anyway.....
Paul
Came back from my Xmas escape yesterday, and started some long overdue stuff: drilling!!!
Here's the templates:

The JamBox didn't get drilled today, as both batteries of my DeWalt are dead.... Tomorrow is another day, thanks for watching!
Paul
Been quite busy the last couple of days, it's nice to have some time off of work and be able to build a lot!! The JamBox enclosure is now drilled as well, all the pcb's for the Űberplex are populated, both Aquaboy pcb's have the last components added and I started mocking up the Űberplex and AquaTwins, to make sure everything fits and lines out nicely.
Űberplex:

While working on it yesterday, I realised I had to reset the jumpers on the ABDX, as I first thought I was going to build it with some 3205's/3208's. That turned out to be a big PITA! I also have my doubts about the location of the toggle switch now it's mounted on the box, I think it is quite vulerable where it is now :(
Last, a question for all of you: I was planning on measuring current draw on both AB's, to see if I could run them from one Roadrage. I have enough space between the 3PDT's to fit 2 RR's (and some more RR boards/chargepumps/regulators in my stash), would this be preferable, noise-wise?
Thanks for checking this out again, have a good 2014!!!
Paul
Great to see you'll be ready to start with 'my' pcb's when I get the build docs done, now that all this will soon be out of the way ;) it'll be a joy working on something small and simple after this.
Seriously: great stuff, insane indeed.

You could put on a little protective cover/shield.
Impressive AutoCAD skills there! I like how you put the size of the hole in the area to be cut out so you know what size to drill.
I suppose you could do the graphics in AutoCAD as well or just import the DXF into inkscape and you have an instant template to make the decal/faceplate/etc.
Inspiring!

Paul,
This looks like it might get rough.
That is a LOT of LFOs and Clocks running under the same hood. You are likely to run into some heterodyning issues.
Just try to keep the Road Rage(s) as far away from the other PCBs as possible and short runs for your grounds and power feeds. Possibly use some double sided tape and plant them on the enclosure wall and behind the 3PDTs. And definitely use the LT1054 for your pump. Even then... you might run into current draw issues.
I know Scruffie just went through a build that used 1054s and was facing current draw limitations. Might want to bounce some ideas off of him!
Good Luck ;)

Thanks! I was expecting loads of (clock)noise issues with this one, so we'll see how it works out. Shielded wire for sure, and probably some shielding between all those PCB's. I'll keep you all posted!
Paul
Looks great Paul. Looking forward to watching the progress on this one.
Looking good! Can't wait to hear these in action!
So I just went into town and returned with supplies to update my testing rig. I'll be putting some proper aligator clips on it, and combine it with an audioprobe. Also bought me a new DMM that does capacitance, frequency, hFe and has a larger range for resistance then my old one. Why? Because this weekend, I'm gonna do the most difficult thing of this massive undertaking: biasing not one but two analogue delays :o
The last two weeks have been spent testing circuits, designing graphics (learned to use Inkscape in the process) and some wiring (mainly pots and 3PDT's, in preparation for the final boxing-up). Also on the agenda for today/tomorrow: ordering knobs and waterslide paper, that's going to be a first!
Paul
Hey Paul.
loved the Grindbox idea!
maaaan this is already the build of the new year! Geee!
great work with the 3D. im still learning how to design in 2...ehhehe
Cheers mate!
This is pure madness. I love it!
Well, as you probably guessed, last week my sunday went a bit different then I had imagined: I completely forgot I promised my wife we'd be doing something together, so no delays were being biased.... Testing rig was finished, so maybe this weekend?
Paul
