Step 2:


The Diodes:

Solder the polarized diode D1and the small signal diodes D3 and D4, pay attention to their orientation since they're polarized components. D2 don’t exist.


Step 3:

The Resistors:

At first, put R1: 1M 1% (Brown, black, black, yellow, brown) and  the 2 x 10K resistors (Brown, black, black, red, brown) And R5: 22K 5% (Red, red, red, gold). R4 don’t exist

Step 4:

The capacitors:

Non polarized caps:

C1: 22nF (labelled 223) 

C2: Don’t exist

C3: 100nF (labelled 104) 

C4: 15nF (labelled 153)  : C4

C5: 1uF polarized (The big black with grey stripe)





























Step 6, the 3.5mm jacks:

At first bend two small legs and solder as the pictures on the pads labelled Audio Out and CV Out. Mount the two jacks. Pay attention to they’re orientation!!!  Insert and solder the small leg on the jack lug to connect the PCB’s outputs to the jack’s tip (Audio Out and CV Out). No need to solder the pad labelled «GND» to the jack ground, because the jacks with nuts provide a good electrical contact.
















































Step 7, the big deal: Soldering the IC!!!

From time to time, a Youtube is more efficiency than a long speak:


Final Step: 

The Eurorack power connector or 9V  Power cable:

When the pin headers are soldered, immediately verify the solder quality & if you didn't forget any pin.

Step 1: 
How to soldering Trough Holes components as Surface mount components:

Only one rule for soldering CMS: Apply solder  on the first pad only, solder the first leg of the component, and then directly solder the rest.

Troubleshooting:

-No CV Out: Check the D4 diodes polarity or the CV jack out pins.

-No sound, no CV:

  1. 1)Check if the rinbbon’s Red Stripe corresponding to the PCB silkscreen.

  2. 2) Check the polarity of the 2x 1N4007 Diodes (big black diodes)

  3. 3)Check the Op-amp polarity, especially the pin N8 (See youtube démo)

  4. 4)Check R1 solder



Credits:

Few years ago, I’ve made my first electronic build. That was a venerable Crackle Box clone, it was a schematic from Michel Waisvisz discovered on the excellent sonelec.com website.

  1. -I want to thanks Michel Waisvisz to his nice creation that inspired Unknown Pleasures. It’s a back to source for me.

  2. -Remi Maillard for the enthusiasm to initiate in electronics many Diyers, what I tried to do myself with Razmasynth.

  3. -I want especially thank also my friend Wilfried «Ikkini» from synthe-modulaire.com. He initiate me in modular synthesis and spend lot of time to test my prototypes and and it is due his kindness and rigorous Alpha & Beta testing that Razmasynth can offer nice, powerfull and noisy modules for DIYers. What? You don’t know the «Wilfried’s Test»?????

  4. -The Resonate 2016 module is purposefully designed Tactile Noise Generator which uses finger contact to produce sounds from Low Frequency to High Frequency Noise. In addition, sound oscillations are converted to tension and provide a CV Output from 0V to 4V, which can be used for control of other modules, synthesizers or DIY guitar pedals.

This module is designed as a Modular Synth DIY and can use any Eurorack compatible power supply or by a single 9V battery or adapter.
