check this out, the "pipe" phaser

[digi2t]

nice....no vero this time!!??? lol

can't wait to hear it!!

Vero? Not unless I take a vow of chastity, become a monk, and retreat to some monestary high atop a rocky outcrop somewhere in the Greek interior. 

[DougH]

That thing sounds pretty f'n amazing... Worth the $50 for the pcb? I think so.

[pinkjimiphoton]

definitely worth the 50 bux!!

just like the concept of vero wherever possible..it's neat to make stuff by hand.

dino's done some masterpieces...but this would be HUGE!!!

Enjoy!!!

I would say this is NOT such a hard build just in terms of the PCB components...it is an incredibly legible layout...there's some repetition and lots of soldering...the only "hangups" to be aware of, like I said are:
- 4PDT switching if you do stereo outputs and want this as a floor unit
- noise proof your wiring
- calibration (but even that's not too hard, honestly)

If you *do* use Ring Stringer, or commercial pedals such as Moogerfoogers that have CV/Gate connectivity for "modular" interaction, I highly recommend doing the full panel buildout with LFO CV output and cutoff frequency CV inputs. Then you can create a little network of weirdness between your pedals...

I have been adding CV inputs to everything..so the other day I was sweeping the pulse width of my Escobedo PWM pedal with the LFO from my Tau. Crazy!

Strategy

OK...

After careful listening, serious consideration, inquiring as to PCB and parts availability, and promising to cut down on my Tim Horton's addiction (OUCH!), I've taken the plunge.

PCB, components, and enclosure, have been ordered. I'm going to use the same type enclosure as my Ring Stinger clone.

Ludwig will have to wait... a tad longer. But not to worry, I ordered an extra enclosure of it as well .

Strategy..... IT'S ALL YOUR FAULT!!!! DAMN YOU!!!!

i have to say , thats the best demo clip i ever heard !

That's kickass! I missed that before, somehow. The bass sounds so badass.

Thanks for the kind word bro. I find that a vero that's got more than 50 cuts and/or 25 jumpers, starts to get a bit unruly, not to mention large. When you get into 1590DD enclosure territory, I find that costs start to increase almost geometrically as well. I've had the Gretsch Expanda-Fuzz in my sights for a while, and I've been trying desperately to keep it as true to the original as possible. But alas, five uA748 IC's just don't allow for an elegantly small footprint vero-wise. In the end, if I insist on staying true to original, the clone will end up being as big as the original.

At some point, you just have to know when to cut bait  . Unless someone REALLY wants one, in a 19" rackmount vero size. That would cost them a bunch of doughnuts though! 

I also ordered the component kit along with the PCB. I figured that it would be best, considering that they know what works, and it would save me from the hassle of shopping from several suppliers.

[pinkjimiphoton]

i'm too cheap at the moment to buy the board and kit, tho that may change....i'm still re-building all the boxes of my mis-spent youth!!

i hear ya tho...there comes a point where it just doesn't make sense to vero some things. this would be too epic!

Hi guys, I have watched this forum for a while but just had to join after reading this thread.  It seems like a big hassle at first, but I have built a perfboard tau, and it's not sooo bad.  The circuit has a lot of repetition and the besides the all pass ladder the main circuit is not too huge.  The whole thing (minus the power supply) fit on a 4" by 4 1/2" piece of rat shack perfboard.  I like to keep board size down by putting components on the bottom side as well, not something everyone would want to do, but it works well for me.  It's maybe hard to tell from the pictures but i laid it out so that the audio and control circuits each have their own power rail, starred back to the power supply.

It is a wildly intense phaser and totally worth building, there are some very nice subtle sounds to be had from it as well, nice chorus/vibrato type sounds with the resonance turned down.  I also added a second LFO which is switchable between triangle, slewed square and sample and hold, another of Jurgen's ideas i took from his flanger project.

I second Strategys suggestions, use shielded wire for all the audio runs and try to keep audio wires away from the LFO frequency pot wires, I know mine looks pretty crazy, but it works great and was also reeeeeal cheep.  (if i managed to actually get the pictures to show up)

Cheers,

jordan


:edit: tried to get the pictures to show up correctly, i seem to be doing something wrong, the pictures of the tau are 1 through 4 in the FX folder

Holy crap I absolutely loath photobucket... what a crapass site, IMO. Imageshack is a bit less of a pain.

Anyways, for the 3 seconds that it actually shows the picture before it redirects to a full-page blank ad, it looks pretty nice!

i got the pics, bro, nice!!!

man...any chance you could label the components on that puppy? cuz it definitely looks do-able...would be a hell of a project, but it looks great!!!

i wish i were evolved enough to be able to figure it out just from the pics!!

peace

Hmmm, I'll try to figure out a better photo system when i have a minute, probably should have done that first but i was excited by all the tau talk and wanted to jump on board.

Jimi, I just laid it out as i went, from one end of the schematic to the other.  It would take way more time to label it all than it would to just build one.  I'm used to building seat of my pants style, but I can try to help if anyone else is thinking of doing it perf style.  I breadboard absolutely everything first, and if you do that for a while a perfboard layout kind of presents itself naturally, with IC's all in a row with the power rails running down the middle, R's a C's on the sides connected directly to the IC pins whenever possible, with a ground rail on either side of the IC's.  Done that way you don't need to make too many connections with resistor clippings, as much stuff as possible goes right where it needs to be.

[pinkjimiphoton]

i'd need a bigger breadboard, i think.

did you ever try diylayout creator?

http://code.google.com/p/diy-layout-creator/

you can lay out pretty much anything on vero, perf, or pcb, and it's free if ya get crazy.

i like the way you populated the perfboard...using both sides of it i'd imagine saved a lot of real estate on the top of the board..

really nice.

i'm always spooky about trying to do something like this on perf...never seemed to have much luck with it.

anyways, some better photos would be ace, but no worries jordan. thanks mate!

peace!

[digi2t]

Yup, no matter how much I don't care for perf, I must give to Caesar what rightfully belongs to Caesar. Perf would make for a smaller board, especially since it's easier to cut across diagonally, whereas vero needs to zig-zag up/down to stay neat. Placing components on the underside saves space as well. Well done Jordan! 

[garcho]

Awesome, thanks for posting this stuff dudes! Might not start this tomorrow, but definitely on the list. Rad demo!

Finally got a good look at that... very nice, Jordan! I had to catch the pic with a right click "View Image" before it went to the blank page.

Great build!!

Whoops, that pic is actually a mutron biphase + stereo panner from a while ago, the tau pictures are the first four pictures in the FX folder, sorry about that.

Jimi, i did try to get into the layout creator but I think I'm a pen and paper guy at heart, great program though.

cheers,
