The Rakit GO! is a USB Eurorack power supply designed for portable modular systems. Now you’ll be able to take your Eurorack everywhere! The GO! has a slew of protection features built in, protecting both the module itself and supply/powerbank as well as greatly reducing the chance of damage to modules through user error. The power supply has a robust and reversible USB C connector for the best possible USB connection. Rakit GO! has been engineered from the ground up, making full use of 5V powerbanks/supplies that are widely available on the market. At only 2HP wide and 27mm deep, it’s ready to fit in any case.

We have taken the guesswork out of getting a good USB C cable, one is provided!

To start using your GO! power supply you will need a passive bus board and your choice of 5V powerbank or USB AC adapter. The passive ‘Sticky’ bus board (available to add above) is a perfect option for your typical lunchbox setup and as the name implies.. its sticky!

Protection Features

Supply/Powerbank protection – reverse voltage, overcurrent (fast eFuse)

GO! Input protection – reverse voltage, overvoltage, undervoltage, overcurrent (fast eFuse)

Module protection – all rails current limited and overvoltage protected

+12V & -12V LEDs indicate bus health (very dim below +-11.75V)

What’s included?

• GO! Module
• 18W High Quality USB C Cable
• 16 way ribbon cable
• 2 x M3 Screws
• Manual

Specifications

• 2hp wide x 27mm deep

Max Current Ratings:

• +12V @ 500mA
• -12V @ 300mA
• +5V dependant on overall system current use (5V can optionally be disconnected via a rear jumper)

These ratings are achievable with a 5V/2.4A supply/powerbank.

Powerbank recommendation & run-time

Rakit have been using Anker powerbanks extensively throughout testing. In particular, the Anker Powercore 20100 works with GO! flawlessly and retails at around £40. This bank has been tested with a small rig for over 8 hours. At full load a 20000mAh powerbank should last around 5 hours (given a powerbank efficiency of 90%).

How many HP will it power?

We think between 48hp and 84hp is a reasonable target, but it’s possible to get more (or less) modules depending on how power hungry they are. Some of the most recent mutable instruments modules, for example, are very power friendly (50mA for a 12hp plaits)

ARPIE is a compact, highly-functional, MIDI arpeggiator that comes as a DIY kit.

If you are looking at this, it is likely you already know what an arpeggiator is, but if not here is a quick description… An arpeggiator is a device which takes chords (maybe played on a keyboard) and converts them into rapid sequences of notes, which can then be played through a MIDI-compatible synthesizer (either hardware or software). Arpeggiation is a very common technique in electronica and chiptune music and is an excellent creative technique. You should note that ARPIE does not make any sound by itself, but rather outputs MIDI note information which can play a synth, sampler, software synth or other compatible sound module.

ARPIE’s Hardware and firmware are open source, and the firmware is based on Arduino, making it easily hackable.

User Guide | Build Guide | BOM & Schematics

Features

• Arpeggiate Up/Down/Up-Down/Randomised/Manual or play all notes in polyphonic gated chord mode
• Mutate and extend the arpeggio with inserted notes: None/Lowest note/Highest note/meander 3 steps forward 1 step back/4 steps forward 2 steps back
• Force arpeggiated notes to a musical scale: 7 musical modes/11 root notes/selectable out-of-scale note handling
• Extend input chord over 1-4 octaves

• Three standard 5-pin DIN sockets for MIDI IN, MIDI OUT, SYNC IN
• Receive, Transmit, Beat Clock and Chord Hold LEDs on control surface, firmware diagnostic/power LEDs on main board, reset button.
• Integral 9V PP3 battery holder and 9V DC socket (2.1mm barrel) which works with either polarity plug.
• Small size (98mm x 87mm x 35mm approx dimensions) and light weight (approx 125g without battery)

Soldering is required to complete this kit. Surface-mounts will be pre-soldered so you will only need to fit the through-hole components.

CV TAB

The CV Tab is an add-on for the ARPIE kit that plugs into the “hack header” expansion socket on the ARPIE main board. It comes fully assembled and tested and adds the following functions to your ARPIE…

• A 1V/octave pitch control voltage (CV) output with 0-8V range and pitch glide between “tied” notes
• A note gate/trigger output at ~10V
• A clock output at ~10V, switchable between 16th note and 8th note steps. Optionally use the output as an accent trigger instead.
• 8kB of EEPROM, enough to store 16 “snapshots” of ARPIE state (even when powered off) for instant patch recall
• LED indicators that blink with gate and clock signals

The 10V clock/gate pulses are generated by an on-board charge pump circuit, even when running ARPIE from a 9V battery or 9V DC supply. 10V is the voltage level output by equipment such as Beatstep Pro and SQ-1 and can be used with Eurorack modular gear or vintage synths.

The Delptronics Module Construction Set is designed to make building DIY Eurorack modules easier! With the Construction Set, a module consists of two circuit boards connected together by male and female headers. No more flying wires to connect panel parts to your protoboard, and no L-brackets needed.

The Module Construction Set is not a kit. It is for DIY module builders who can read a schematic and build a circuit on a breadboard or protoboard. The circuit boards used by the Module Construction Set are laid out the same as a breadboard.

There is even a Panel Maker web app for making panels out of PCBs – with no circuit board design experience needed!

Each PCB set comes bundles with male and female headers for connecting the control board and component boards together. A 2×5 Eurorack power header is also supplied.

Control Board

• A flexible grid layout that can accommodate up to eight controls
• Room for two additional pushbuttons, and two LEDs
• Up to eight jacks
• Available in 4 HP, 8HP or 10HP

Component Board

• A familiar layout similar to a protoboard or solderless breadboard
• A Eurorack power header – prewired to the power rails
• Reverse power protection diodes
• Power supply filtering capacitors.
• Space for a voltage regulator (if your circuit needs 5V or 3.3V)
• Mounting holes for securing the board to the control board with an 11mm spacer

Note that the 10 and 8 HP control boards are connected parallel to their corresponding component board, while the 4 HP control board is connected perpendicular to a 10 or 8 HP component board.

8HP vs 10 HP

The control boards have spaces for the same number and type of parts, just spread out more. The main difference between the 8 HP and 10 HP component boards is that the 10 HP is easier to work with. The 10 HP design emerged from comments from students using the MCS in classes. Some students found the 8 HP boards a bit cramped.

The 8 HP component board has the V+ and V- power rails running down the center. That makes it a bit harder to connect power to chips and other parts. The 10 HP component board has the power rails along the edges for easier wiring. That also creates an extra pad for each column in the center of the board. You can even shift a chip to the right or left one column if it has more connections on one side.

Another difference is that the 10 HP component board has two pads for each component connection. That can often make laying out a circuit easier.

Compatible Control Panel Parts

Switches: Standard sub-mini toggle switches, with 2.54mm / 0.1″ pin spacing
Buttons: Standard 6x6mm tactile switches, 14 mm or higher
Pots: Alpha style potentiometers, must be raised style (10mm high)
Jacks: PJ398SM, PJ366ST / Thonkiconn or clones

The Majella MCVC is a four-channel, expandable MIDI to Control Voltage (CV) converter. This is a DIY kit which requires soldering and basic (Voltmeter, at least 3 decimals) measurements.

The MCVC is a straightforward interface between the Eurorack synthesizer systems and devices that communicate using the MIDI protocol. The MIDI-CV Converter bridges the gap between MIDI and Eurorack systems, because it converts MIDI messages to control voltages, which correspond to Eurorack synthesizer signal standards.

You can use the MCVC to output 4 mono channels (MIDI channel 1-4). In “mono” mode the MCVC uses “last note priority”. You can also use the MCVC poly mode to play 4 voice polyphony (MIDI channel 1).

You can expand the Majella MCVC with four voices at a time and expand up to 20 voices using the Majella MCVC Expansion module!

Please note this module uses the 5V rail (16 pin Eurorack connector).

These blank panels are made of printed circuit board material and are 1.6mm thick. Perfect for filling in those gaps in your case. One side is patterned while the reverse is pure black (the pure black sides can have slight imperfections because of the manufacturing process). Note, the 2hp blank is not black on the reverse graphic side.

The 2hp and 4hp designs are based on a Turkish carpet motif representing ram horns (boynuz): a symbol of power.

The 3hp and 6hp blanks are designed using the hilbert curve fractal.

Unlike almost every other piezo pickup design, this 3D printed enclosure allows you to twist off the lid if/when you need to repair the solder connections. That’s right, this thing has threads!

We suggest using tape to attach these onto the thing you want to pick up the signal from. The 1/8” jack on the side means that you’re going to have way too much fun plugging this thing into your eurorack modules, or really whatever can accept an 1/8” jack.

Dimensions:

• Enclosure – 48mm x 17mm
• Piezo size – 35mm

The concept behind this module is to Merge the guitar pedals and the modular synths together. “The idea stemmed from the fact that we wanted to use our pedals in conjunction with our ever growing eurorack rigs.” Merge allows users to utilize different parts of your signal than just the sound. It extracts amplitude information and generates control voltages that can be used in conjunction with other modules and eurorack level equipment. With an instrument input, FX loop (each with their own independent level control), and an envelope follower this module opens the stargate to new and unexplored sonic territory.

Build Document – Assembly Guide

Controls

• IN – Signal Inputs. The two IN jacks are tied together so you can use either a ¼” or ⅛” cables. (Unbalanced)
• LVL – Amplifier gain control
• GAIN OUT – Amplified signal output
• GAIN SEND – The same signal that is present at “GAIN OUT” is also present at “GAIN SEND”. “GAIN SEND” is normalled to “RECTRCV”, meaning, if nothing is plugged into “GAIN SEND” or “RECTRCV”, then the jacks are connected together. If you plug a cable into either jack then the connection between them is broken. This allows you to send the amplified signal to other modules for processing and then back into the next section of Merge. Alternatively this also allows you to use the different sections of Merge independently on different signals.
• RECTRCV (Rectified Receive) – Normalled to the signal present at “GAIN SEND”. Serves as the input to the envelope follower section of Merge.
• RECTOUT (Rectified Output) – outputs a fullwave rectified version of the input signal. Fullwave rectification essentially means to take the negative portion of a signal and flip it to be positive. (waveform offset for visual clarity only).
• FRICTION – works in conjunction with “INERTIA” to fine tune the response time/envelope smoothness.
• SCALE – controls the output level of the envelope signal.
• ENVELOPE SIGNAL OUTPUT – Outputs an envelope signal from 0V to some positive value set by the scale.
• INVERTED ENVELOPE SIGNAL OUTPUT – Outputs an inverted envelope signal from 0V to some positive value set by the scale.
• ENVSEND – passes a copy of the positive envelope to the next section of Merge and is normalled to “LOGIC” the same way that “GAIN SEND” and “RECTRCV” are normalled together.
• LOGIC – Normalled to the signal present at “ENVSEND”. Serves as the input to the logic section of Merge.
• GATE – sets the threshold level to turn the gate output on. The gate signal will stay high as long as the input signal is above the threshold.
• GATE OUTPUT – outputs the gate signal based on the envelope information
• TRIG – sets the threshold level to output a trigger signal. When the input signal goes above the threshold, a trigger signal will go logic high, then almost immediately go logic low again. The trigger generator is reset when the input signaldrops back below the threshold level.
• TRIG OUTPUT – outputs the trigger signal based on the envelope information and the “TRIG” knob
• SND SECTION IN – eurorack signal input to effects loop
• SNDLVL (Send Level) – gain contrl for the input of the effects loop
• MIDDLE 1/4” JACK – output intended for, but not limited to, sending signals to pedals
• RTN SECTION OUT – eurorack signal output from effects loop
• RTNLVL (Return Level) – gain control for output of the effects loop
• RIGHT 1/4” JACK – input intended for, but not limited to, returning signals from pedals

Product is a full featured modular synth voice in 26HP which can be used without any patching or as the heart of a modular system. Each component part is fully modular, but also features pre-patched normalised signal paths for fast set up of new and exciting sounds.

Product features a motherboard on which all pots, switches and sockets are mounted, this is also where the pre-patched normalising happens. So the onboard LFO is available for both FM and PWM of the VCO. The three VCO waveforms are available at the three VCF signal inputs. 1V/oct input, LFO and ADSR are available at the three VCF signal inputs. By some cunning switching, the VCA can be operated by either ADSR or gate input, alternatively it can be set to drone position. Also available are signal outputs from the LFO and noise generator. All pre-patched connections can be broken simply by inserting a jack into the relevant socket.

Product is a combination of three individual Frequency Central modules:

• XVCO TWO (based on the Roland System 100M)
• Raging Bull 3.0 VCF/VCA (based on the Moog Taurus Mk I VCF and VCA)
• System X Envelope (Based on the Roland System 100M)
  …plus…
• Onboard LFO for PWM and FM
• Onboard noise source

To simplify the building process, there are three daughterboards that plug into the Product motherboard: the VCO daughterboards, the VCF/VCA daughterboard, and the ADSR/noise daughterboard. First you can build and calibrate the VCO, plug it into the Product motherboard, get it running and have some fun with it. Then build the VCF/VCA daughterboard, and add it to your expanding modular synthesiser. Finally you can build the ADSR/noise daughterboard, and your synth is complete.

XVCO TWO

Roland 100M VCO adapted to Euro. The hard-to-find/easy-to fake ua726 diff pair has been replaced with a UL1111.

• A six position rotary switch for octaves gives plenty of range. The PITCH pot is fine tune.
• Individual outputs for ramp, square and triangle – an improvement on the original.
• built in chip heater to keep you nice and stable in this topsy turvy World!
• Onboard LFO! Yes that’s right, an onboard LFO (thanks MC202) for introducing FM and/or PWM. Super!

RAGING BULL 3.0

Based on the legendary Moog Taurus Mk I VCF and VCA. It has a lovely, thick Moog-like quality, which is further enhanced by the drive you can get out of its VCA at higher settings. A big part of the sound of the Taurus was the way in which the VCF interfaced with the VCA, so on Raging Bull the VCA is always in the audio path. A toggle switch allows you to select ‘always open’ or CV control of the VCA
