Interested in Tau Pipe Phaser / Flanger boards ?

Is there a simple way to hook a 2-wire bi-color LED up to the two LED outputs? I'm using the Bridechamber front panel which is set up for only one LED. I'd like to use the MOTM standard Lumex LED's, but I don't see a 3-wire version of their bi-color, just the 2-wire. Thoughts?

thanks
eric

thank you very much.

(i'm so excited Cool

)

Al least, I finally decided to leave off the two outputs potentiometers as I don't really understand their usefulness.

two sources, one output, you need a pot for varying blend (as for a Dry/Wet pot)

but, with two sources (main, aux), two outputs, mixing and panning would be made in the main mixing desk...

As you found earlier, Juergen, the Pipe's ability to bend pitch makes for a nice chorusy sound. Multiple all-pass filters are fun Smile

Apparently my 20-pole "Tau" phaser project http://www.jhaible.heim.at/tau/jh_tau.html has created more demand than I had expected.
The PCBs were sold out soon, and I've started to keep a waiting list, to see if another manufacturing run would be justified at some point.

I have now reached this point, not least due to a big order of Tau PCBs from Scott Deyo of Bridechamber. Smile

If you want to have one or more Tau boards as well, please let me know as soon as possible.
Pricing is "as usual": EUR 27.00 per board, plus EUR 4.00 shipping flatrate.
(Ask for a discount if you want 5 boards or more, and expect higher shipping
costs if you want them sent by registered mail.)

You probably know about my infamous order forms by now. Smile

I really need the orders in that form, because of my clumsy means of
book-keeping.
Dont forget to use the required email subject line (that's the text that is
visible without opening the email. Smile

)

Please send an email in this form, if interested:
(my email adress can be found at the bottom of my homepage, http://home.debitel.net/user/jhaible/hj.html . No Forum PMs, please.)

=============================================================
Subject Line of your email:
"Tau Reissue Order [n] PCBs" (where [n] is the number of boards you want to order)
=============================================================
Email Text:
"I'm ordering [n] Tau Reissue boards (fill in number of boards again)
for EUR 27.00 each
plus EUR 4.00 shipping flat rate

I know that I'm only buying a printed circuit board, not kit, and have no
guarantee to build a working Phaser from this. As a buyer, I'm responsible for all aspects of safety for the device I'm building with this PCB; no such responsibility may be assigned to the seller and designer of the PCB. The descriptions how to build a Phaser, given by the silkscreening on the PCB, on the internet and elsewhere, are just to be considered helpful hints, and do imply any responsibility of the seller / designer for damage and danger that may arise from what the buyer is building with the PCB.
By ordering one or more PCBs, I expressly agree to these terms.

Looking forward to hear from you!

PS.:
As my waiting list contains a pottpurri of actual pre-orders and just signs
of showing interest, I'm sending this mail out to all on the waiting list directly, too. Regardless of what you've mailed me before, please send the
order described above, if you're still interested.

Hi, I was wondering... The strength of the design is the large number of allpass filters...I wonder what it would sound like if you tapped the output of half the total number. Just musing aloud. Thanks again for the project; I'm glad that so many are finding one of my favorites to be as useful and unique as I've found it to be.

Hi Peake!

I haven't even built my Tau yet due to other projects, but since you're musing aloud, I've always got time for that. Very Happy

Tapping off different phaser stages intrigues me too, and here's and experiment I've been planning: a stereo configuration tapping odd stages for the left output and even stages for the right output. I'm figuring they could just be passively mixed. I've bounced this idea around with Scott Stites a while back, and IIRC, he tried it with his 32-stage Multi-Phaser with good-sounding results. Anyway, just thought I'd add some more food for thought. . . .

Regards,
Joe

Note: At this point, the Tau Pipe Phaser/Flanger thread spawned a topic so intriguing that it deserves its own thread (The Dimension T thread). The subject has been split off to here:

On the topic of SMD parts, this is how I see it:

As long as you select the SMD parts at a sensible size (ie. 0805 resistors, regular eg. S08 ICs with a pin spacing of 1.27 mm, the occasional 0603 part) & you have a half-decent soldering iron & some good tweezers the whole process is really no more difficult than building a regular board. We might as well face up to it sooner or later !!

Where I get frustrated is when some of the nice modern parts, eg matched pair transistors, are only available in stupid small, 0.5mm pin spaced outlines! Now although these can be done by hand, you'll soon get a headache!!

So guys, don't be afraid, it really isn't half as bad as you might think! Make sure that you have some proper solder with lead in it too, none of this lead free stuff (OK its a very good idea to make all the disposable white goods with this stuff - but yet another pain for the home constructor).

Pete.

Hi,

can anyone easily add another cv linear input ?

adding an 2k7 resistor between R56 and R55 ? or at U5A -IN (pin 2) ?

BTW, the SMOOTH function (which only consists of a cap tied to ground ?) is great.

Just finished my Tau Pipe with a Bridechamber front panel. I decided to leave off the output trims. It looks like this:

Tau Re-issue boards arrived some days ago - prototype from this run built and tested.

I'll be sending invoices this week - don't send money befoire you get an invoice.

First shipment will go to Bridechamber, who helped to make the new run possible.

Juergen is there many pcbs left?
I would love one but cant do much for another month or so
Will it be safe to wait another month or should i do something like sell my parents Wink

Everyone who has pre-ordered boards from my re-run of 20-Stage "Tau" Phaser
boards should have received an invoice by now.
I've shipped them today to all who have paid already.
Next batch will not go out before 12. April, because I'm on a business trip
next week.

Hi Jurgen, I just got my Tau Pipe Phaser(re-run) PCBs. Thank you.

A couple of issues I need your help.

1. I have seen in the “Deluxe Version” of the “Tau” connections that on the output there is provision for a 10μF non polarized Electrolytic and a 100k resistor that do not exist on the “Basic Version”.
I have read the relative messages and have understood the issue.

Is this also applicable to the Solina-Triple Chorus output connections?

2. I have problem in finding a Tempco resistor. I have looked at Reichelt/Banzai/Das Musikding, but have not seen any code for Tempco resistors. I may have missed it. I will appreciate some supplier suggestion and/or an order code number for a 1k one.

Many thanks and Best Regards

Stavros
