Zlob Modular - Attenumixer (Panel PCB)
sold out at the moment
This is the panel PCB version of this kit.The Attenumixer is a 4 HP 3 channel passive attenuator and mixer module.Each channel is normalled to the sum(VI) so it can be used as a 2 channel mixer and 1 channel attenuator, or a 3 channel mixer, or as 3 separate attenuators. Normalization to the sum is broken by inserting a jack into the outs of channels I-III. The Attenumixer works well with both cv and audio, although the potentiometers have a linear response. Since the module is passive there will be signal loss at the sum out.DIY-Kit-Type:Panel/PCB Kit. This is a do-it-yourself panel/PCB kit, no parts are supplied, you will need to source them yourself.

Zlob Modular - Entropy (Panel PCB)
only 2 left
This is the panel PCB version of this kit.Analog random voltage and noise generator in 3HP. It features sample/track and hold normalled to white noise with a toggle switch for selecting sample (switch right position) or track (switch left position) and hold function. There is also a PCB trimmer(at the top of the motherboard) to adjust the spread(gain) of random voltages out from “scalar” (low gain, counter clock wise) to large interval jumping (high gain, clock wise). All analog white, pink, and brown (red) noise 10vpp~ (dependent on lower PCB trim). Smooth (infra red) random cv out at 10vpp with 2 range settings from wiggly with (more events, switch in left position) to almost random rise and fall envelope behavior (less events, switch in right position). White noise pcb trimmer sets the amplitude of the noise which in turn influences the rate of the infra out. LED solder mask windows indicate positive(red) and negative(blue) voltage crossings.DIY-Kit-Type:Panel/PCB Kit.

Zlob Modular - Entropy Expander (Panel PCB)
available
This is the panel PCB version of this kit.Analog random voltage and noise generator that expands upon the features of the Entropy Euroack Module in 3 HP.The Entropy+Expander packs together some of the most random voltage options in 6 HP. It provides a controllable “Glide” (slew) out for the S/T\H, a comparator with a controllable rate (“Thrsh”) of random gates (“Rand Gate”) out with an input to compare other waveforms (Comp In, inserting a cable into here breaks the white noise normalization), and high pass filtered white noise resulting in approximate “Blue noise” (+3db/octave) and “Violet noise” (+6db/octave) outs.The unique part of the circuit is a voltage controlled A/B switch thats normalled to the “Rand Gate” out that’s switching between the S/T\H out (left Blue led window) and Infra out (right Red led window), the Glide control also effects the S/T\H coming out of the switch so you can get really random results from the “Entropy Out.” Inserting a cable into “Switch CV In” breaks the random gate normalization and lets you toggle between A/B (left S/T\H out and right Infra out, indicated by the led windows) with your own gate or trigger.There is a jumper on the pcb to select if you want glide on the S/T\H at, Entropy out, or un-slewed operation. There is also a trimmer for setting the amplitude of the incoming signal at “Comp In” which sets the frequency range of random gates. This may have to be adjusted depending on your Entropy version. The random gate range can also be set up more as a noise oscillator by turning the pcb trim (clockwise) up or it can be set so random gates are extremely slow (trim counter clockwise) with minutes between random gates.DIY-Kit-Type:Panel/PCB Kit.

Zlob Modular - Push VCA (Panel PCB)
available
This is the panel PCB version of this kit.The Push VCA is a 2 Channel DC Coupled Mute Eurorack Module in 2 HP. It features 2 independent unity gain DC coupled VCAs with led push button mutes. A mix of both channels is available at the sum, but all outputs are available simultaneously. The newest version has normalizations to +5v, so with nothing plugged into the ins voltage can be toggled on and off at the outputs and up to 10 volts can be output at the sum. The buttons are latching, not momentary push buttons. LED button color may vary, but it will always be two of the same color.DIY-Kit-Type:Panel/PCB Kit.

Zlob Modular - Skew Fade LFO (Panel PCB)
only 1 left
This is the panel PCB version of this kit.Analog skew-able xfade-able LFO Eurorack Module capable of a plethora of waveforms in 3HPIt has three rate settings ranging from 3 minutes and 30 seconds a cycle up to audio range at 20 hz. Triangle waves can be skewed between ramps and saws, and square waves pulse width can be adjusted from inverted triggers to triggers. The LFO’s unique feature is voltage controlled cross fading through the (“Fade CV” in) between square/shark tooth/sine waveforms provided at the “Fade Out”. All outs are also influenced by the skew knob resulting in many complicated and asymmetrical possibilities at the “Fade Out.” It can even be self patched(ie triangle or square into fade cv) for an extended pallet of waveforms. The “Fade CV” in expects a bipolar voltage 10vpp to fade from square to sine with the fade pot at noon position. Bicolor led provides constant display of positive and negative voltage crossings.DIY-Kit-Type:Panel/PCB Kit.

Zlob Modular - VC F3DB (Panel PCB)
only 1 left
This is the panel PCB version of this kit.VC F3DB stands for Voltage Controlled Fixed Filter Feedback Distortion Bank. The simplest description is it’s an analog 16hp six band voltage controlled fixed filter bank. But with the additions of so much gain, clipping, feedback, and self-oscillation it becomes a very flexible and unique gestural sound sculpting tool capable of; graphic equalization over 6 octaves, multi-band distortion, spectral processing, crude vocoding, multi-frequency envelope following, self-modulation, and even as an instrument on its own. With no input it can be used as a pseudo chaotic “harmonic” feedback oscillator.The filter frequencies were specifically chosen to emphasize more ambiguous and dissonant intervals. Although the frequency bands are spread out over many octaves I purposely tried to leave out “3rds” besides a major 10th at the top frequencies to even out all the dissonance below. But the frequencies aren’t exactly equal tempered, so it’s relative. The bands roughly equate to F2, B3, F#5, C6, F7, A8.The design is based on the Moog 914 filterbank, which it borrows the frequency bands from. But this circuit uses active filters with opamps inspired by YU Synth opposed to passive cells using inductors on the original. The 88hz is a low pass -24db/oct and 7k is a high pass -24db/oct, the rest are -12db/oct band pass filters all with a Q around 4.The hard and soft clipping circuit on the input is fairly standard which appears in many different iterations of classic guitar pedals. But it has a lot of gain and can even boost line level signals. What makes it a bit unique is the feedback on the clipping circuit which needs to be turned on by the GFB(gain feedback) switch and the amount can be controlled by the Gain FB pot which can add some fuzz/bite to the signal depending on which clipping switch is engaged or at the extremes it will self oscillate from audio rate to LFO sort of clicking range. All the clipping stages in the module are using silicon diodes.Consult the Signal Flow Chart to the left for a rough visual breakdown of the controls,in/outs,normalizations, and optional settings for the module.Each band can also be muted by the top toggle switches or clipped (at the VCA) by the top slide switch which makes this design a bit different than other filter banks. As well as the overall feedback section(bottom middle) takes the sum/all bands out through a VCA (controlled by the feedback pot and FB CV) back to the input gain/clip circuit. and you can also tap into this using different sends/bands to the FB In jack to break the normalization. With this extra feedback “resonance” you can get more whistley and howly filter sounds kinda like the Serge res eq, which can also go into self oscillation.All CV ins are expecting +5v to open the VCAs (they wont respond to negative voltage), once you get closer to +8v or so it can clip the VCA regardless of the gain settings or clip switches. Output amplitude in high gain settings will exceed 10vpp and can get up to 20vpp. The envelope followers tend to stay around 0-5v out, but with clip switch active they can go up to 10v.Since this is a high gain module there can be bleed between the bands in certain configurations and situations. Also in high gain modes with higher frequencies the 2.8k and 7k bands can bleed a little with the VCAs closed.This is a highly involved DIY all through hole project. It is a long build with 5 different pcbs to solder and assemble.DIY-Kit-Type:Panel/PCB Kit. This is a do-it-yourself panel/PCB kit, no parts are supplied, you will need to source them yourself.
