Tap Tempo Trem-O-Phase, because doing hassle free projects is not permitted..... now laughing of it... ...but Faawwwkk that i wanted to throw it by the window couple time.. hahaha!
So this is David's TwinPeak Tremolo into his Liquid Mercury Phasor, in theory and practice the idea seemed to be fairly easy, i might have overlooked this one a bit i did couple newbie mistakes (always good to remind you, that) and other stuff that where just out of my knowledge that i had to fry them in the name of science to know if it would work or not.
Picstory accompained with all the problems i went through :D

At this stage i had drilled the enclosure and thought i had took good measurements for everything... but NO! the jacks on the side that where suppose to be the main in and out even if at the lowest they can in the enclosure so they sit flat, i had'nt thought of the sandwiched pcb design these are... so it was sticking too high out of the enclosure so i can put the lid on, so i used the jacks that where meant to be the switching loop between the effects.
I also had to dremel out the center top screw standoff so i could fit the jack, that was part of the plan tho... what would be a build without a lovely dremelin' session.

I grabbed the TwinPeak fully populated and tested PCB from Jubal81 wich is per his habit populated and assembled using quality components and great craftmanship, no problems would occur with this part... ...i had thought... ::)
(https://scontent-ord.xx.fbcdn.net/hphotos-xaf1/v/t1.0-9/11053274_823464237728868_5696386501044636674_n.jpg?oh=c7229da88551e833041d2e13eae4b7b3&oe=55B95C98)
Dropped the primary Phaser pcb in there and decided to plug the power just to see if my tempo LED was working, it was, unplugged and continued... and that's where it turned ape shit! haha
After i added the second pcb of the Phaser, i went to try the effect, tapping the tempo was just affecting the phaser, the trem was sounding wonky... not responding accurately to the settings and was'nt able to get any of the modes to work right all together, when i fixed one, another would start bugging...
I then spent more time looking at the schem and realised that one of the tap tempo input receives 5V but i had connected both tempo together on the same switch, so i was in fact driving a bit under 10V to the TAPFLO tempo input pin... for some mysterious reasons, it only fried the Trem MCU, phaser was all good.
But then i had a problem, i wanted a remote out or external Tempo In using a Tip/Sleeve Jack... so if i wanted to do that i had to sync both MCU together, so i hooked a wire to the Clock output of the phaser Taplfo so i can then send it to the Trem. Luckily i had an extra flashed MCU courtersy of Cody (selfdestroyer), so that was a no brainer now. Once that wire was hooked i took some reading of the clock output, i hoped that it was only sending the source clock signal through it... ... but No! It's outputing whatever the setting you have dialed in... so my 2 effects would'nt be independant anymore as all i wanted was to have the source tempo to be sync'd...
Plan B:
I'd had to use a DPDT for the Tap but i had only drilled one hole for the Tempo LED and it would only show the behavior of one of the 2 effects... blurgh blurgh blurgh blurgh... a fattie later... as i now really needed to calm down... this kind of stuff irritates me... lol. I thought.. YES! i'll use a bicolor LED! Nooooo.. they are common positive and i need common negative for this as the blinky blinking comes as V+...meh... So i waded through the stash of LED remembering that i had once ordered wrong Tri-Color LED that had a common negative...... FOUND 'EM!
By that time, the Trem was now out as i tried bunch of things on it before i found that i had fried the tapflo, took out the TS jack for remote, replaced with a TRS isolated... will now need a TRS cable but it's ok, that flexibility i wanted is now there.

Final Gut Shot! ....well.. maybe not, i still have an issue with some DC coming out of the Trem output in the BlackFace mode and the Treble only being wonky....
I brought a mod from my past Mutron PhasorII clones into this one aswell, added a 4PDT toggle to switch between Phaser and Univibe modes and made the 4-6-8 stages switch external as it gives a good load of different filter voicings when the Vibe mode is engaged. I used Tayda LDR as i had used them successfully in my PhasorII builts and that i did'nt had any VTL5C3/2 laying around, those will be swapped as i have some on their way courtesy of Jason :)
And too go along my multi-crowded pedalboard concept i used a bit of dremelage for the enclosure finish...

Now that it's almost done... just needing couple fixes and fine tune the whole thing, it's very satsifying and will do exactly what i wanted. Props to David for putting together these circuits, they are awesome and very easy to put together despite their complexity if you do everything by the rules, thanks to Cody for the TAPFLO, legend like DMM measurements on his TwinPeak to help me out and Jason for the flawless TwinPeak setup that i ruined! Ha Ha....
Rej
Wow. Daaaamn that's a nice looking build!
Wow, that's quite a build, Rej.
This makes me giggle. So many knobs!
Great build! I always love a good debug story!
Niiiiice!
I finally thought of what your build enclosures look exactly like Rej......
Rhino skin! 8)
Epic offering by the way... :o
You lost me about 10 percent into your story but awesome work indeed. I bet it sounds excellent.
Much thanks guys!

Blammm. Nice job as usual Rej!

EPIC! :o
Quite an ordeal to make it happen, too. Can't wait to hear what it does.
Tap, tap, tap-a-roooo!
Thats a super build Rej. Multis are always a pain in the ass, def harder to squeeze everything happily in there than they look.
Kind of short on knobs isn't it?
Wow!
Chuck
I'm so glad you stuck with this build Rej. This is cool. This one really deserves a VIDEO!!
This is so over the top! So if I understand correctly, you have a single tap tempo stomp to get both effects in synch? But you can also use the rate knobs to get them going at different speeds? So do you have TAPFLO chips in each build? I only see one in the Twin Peaks.
Rej this looks FANTASTIC!!!. I'm a bit curious as to what LDRs you used for the Liquid Mercury. I noticed it isn't the VTL5C3/2. How and what did you use there...
Most impressive :-)
Nice one. The most frustrating builds are often the most rewarding ones when you you get them to work properly.
Man you must have stayed up hella late last night to get this done! Great job Rej, this was a fun one to watch you defeat. This game me the push to get mine boxed up this week. Also, glad I was able to help you in anyway... it was fun.
Cody
Killing it as usual, Rej!
Thanks for the comments guys, after all the adventures i got with this built, it's much appreciated! :D

Thanks man, i've used the regular 5mm LDR that Tayda sells, been using those successfully in so many circuits, they have proven to be the ONE good thing in the Tayda stable. lulz

I think that the expression: Bitches always get paid back, took all this sense with this one on my case... i gave so much trouble to people with the STM800... i had to get my fair amount of problem. ;)

Yep, there's a TAPFLO in each circuit, so they either can be sync'd or have totally different speed using their respective rate knobs. The Phaser MCU is located on the pot PCB, why you can't see it from those pics.

I'll sure make a clip of it once i have fixed the remaining little issues with the Trem :)
The idea for me was to be able to recreate that sound, but add in flexibility and have both circuits TapTempo..
In that clip i'm using an Empress Trem and PhasorII built on Brian's Nutrons layout.
Hey Rej, do you read minds? Something like this is what came to my mind when drolo released the phaser, and your video was the trigger!.
It looks awesome, and the phaser mods have to be killer. One could spend days tweaking sounds with this box.
Kudos. I'm sure it has been hard work, but the result looks awesome.
Looking forward to the new video :)

Whooo! Awesome

Thanks Adan... at some point for what a phaser is... this might be a bit of extravagenza excessiveness... but yes! It got it's load of possible sounds and useable sounds that is!
For those interested in doing the Vibe mode, here are the values and locations:
C9: 15nF
C10: 220nF
C11: 470pf
C12: 4n7
C12 is really close to the 6n8 per stock values, one could also use a 3PDT and acheive similar results.
Those LDRs, is that 2 legs in 1 hole on 3 of the 6?
far out... that is epic in build and in sound! what a great idea & execution!
Great flaming globes of sigmund!!! That's sweet.
Beautiful work and demo Rej! I'm glad all the hard work paid off in the end. :)
