Sadly I have not either. I've got a few projects going right now that I need to finish up first
After seeing your struggles with the enclosure, and not really having much luck finding a bigger enclosure, I was thinking of mounting everything on a metal panel too and building a wood box to house it. I have a handicapped parking sign that might be cool to use for that
I'm very interested in a board if you decide to do another run. I've been planning on making a full sized Biphase for over a year now but I haven't bit the bullet. I ran the price on doing it and the minimum price I calculated was $150, and it would probably end up being closer to $200 knowing me. Doing one on your board would be far cheaper and much smaller. Do you include the expression pedal to control the sweep? I think that is probably the single most important feature of the effect. I want to use that to create the ultimate version of the Korg Mr. Multi.
I kinda never really got round to finishing this, it's still on my bench.
I had it sorta working but it was noisy and ran a bit hot.
I started to V2 board recently but I'm still working on it.
It has full functionality, with outputs for the expression pedals. A lot of the info out there is a bit wrong with relation to the expression pedal, I found the original schematics and have the correct connections sorted out.
Hey Phil. I still have the PCBs sitting since I haven't had time to build it. Should I not even work on it? Btw, you get my email a few weeks ago?
No man i didn't get an email, i woulda got straight back to you.
Er, as for the BiPhase, i think it'll work. I got it working but I had a bit of trouble boxing it and then kinda ran out of steam. I didn't ever get to test out the expression pedals (i couldn't afford one at the time) and i didn't at the time have any info on how to calibrate it, so it sits on my bench staring at me and makes me feel sad.
Once i got this lovetone ring modulator and the schumann stuff out of the way i'll revisit it. I'll probably make two larger boards and stack them with board mounted controls.
You wanna resend that email, i'll defo get back to you if it appears.
Eh, when i get a chance i might go for them biphase then, or if need be I'll chip in for the V2 board when its ready. I figured you didn't get it for some reason. You know what I'll send it to you on Facebook. This way I know you'll get it. Lol
I want a Korg Mr. Multi, but the problem with it that I see is that it's a mediocre wah and a mediocre phaser, but together they sound great. I want to try it with more intense pieces. I have a Crybaby and together with the Biphase I'm dreaming it will sound amazing. If the Crybaby isn't good enough, I might build a Tychobrahe Parapedal or some formant producing one. But that's all in addition to the Biphase being a wonderful phaser on it's own.
Also, in the mega compilation that I posted earlier, there are some very clear images of the schematics redone by one of the French gentlemen who have done clones, but I did notice a few values seem to be in error compared to the hard to read original schematics. There are also slight differences in the traces between the ones provided by Patroche and the ones provided by Boris. Most notably, on the Controls trace, Boris shows 4 pads on the top middle right with some links, while Patroche only shows 3. I went through the schematics and Boris' seems correct, but Patroche has actually built his and he seems happy with it.
It appears they are available there. That project misses the most important part though: the expression pedal. To me, that's what truly makes the Biphase special. Very few other phasers do the expression pedal sweep.
The pedal PCB design misses out all of the wave shaping as well, it's not faithful to the original.
I have a new design for it but sadly Dino has been taken ill and the design is with him for checking. Hopefully it won't be too long before he's back on his feet
I'm very glad to hear that you're still working on it. Is there any way that the waveshape could be set by a pot to adjust between the sine wave and square wave instead of just one or the other? I know the 4ms/commonsound Phaseur Fleur/Moire has a waveshape mod that uses a pot instead of a switch.
I'm not sure about the waveshaping, there's quite a bit of circuitry envolved, which I think is missing from the pedalpcb design. I'm reasonably sure that is just two mutron phasers in a box, the biphase is a little more complex than that. I might be wrong though, I haven't seen the pedalpcb schematic.
Until Dino is better this project is going nowhere, and that might be some time.
The Duo-Phase has LFO sync and phase inversion. The only thing missing in terms of waveshape is the square wave modulation.
With that said, it is not intended to be a 100% feature-accurate clone of the original but it ticks all the most popular boxes.... Switchable 6 / 12 stage operation, synchronized or independent LFOs, mono or stereo operation, fits into a smaller 4S6500 (1590XX) enclosure, and it runs off a standard 9VDC power supply.
At some point I will likely add square wave and expression control, but at the moment that isn't a priority.
Those who insist on meticulous authenticity are going to want your PCB instead. Hell I'll probably have to grab one myself at some point. =)
