The Synth Pointer style will be very familiar to fans of Synth Tech, Pittsburgh Modular, Rebel Tech and L-1 modules. They have a 6.4mm / 0.25″ shaft with setscrew and the same sturdy brass insert as the 1900h clones.
The ‘small’ knob was previously referred to as the ‘SynthTech’ style knob.
These are direct drop in replacements for the common Alpha 9mm vertical trimmers and metal shafted potentiometers. They are also directly compatible with many other 9mm pot footprints from Bourns, Panasonic and others, see the datasheet for footprint details.
These pots are more ergonomic due to the longer shaft and they are easier to read than the competitive offerings due to the white marker line. These pots also have a 15,000 cycle lifespan compared to the Alpha 9mm pot 10,000 cycle lifespan.
You may recognise these pots from recent Intellijel and WMD Euro modules and the Bugbrand WorkshopCrusher.
This B50K Linear pot is suitable for the ‘Scale’ pot on the Turing Machine.

Thonkiconn Eagle v6 Library Part – thonkiconn.lbr
Thonkiconn Eagle v5.7+ Library Part – thonkiconn_eagle_v5.lbr
Thonkiconn (PJ301M-12) is a new vertical mount 3.5mm switching mono phone jack. It is supplied with a hex nut (knurled nuts will be available next year).
The mechanism is identical to the ‘Erthenvar’ jack type (PJ301BM), it’s primary purpose is as a direct replacement of the popular Kobiconn 3.5mm jack but with a 100% vertically integrated footprint, i.e. no perpendicular ground pin. This jack is used in the newer Make Noise modules (Maths 2 etc.)
A really great bonus of these parts is they fit neatly into breadboard/stripboard/veroboard.
All materials used are RoHS compliant.
You can purchase extra bags of nuts and washers here.
NOTE: Please refer to the notes about the PCB HOLE in the Thonkiconn Jack Datasheet.
It is advisable to drill a 3mm hole in the PCB directly under the jack barrel centre or avoid routing traces or ground plane in that area.
Click Image below for more detailed Datasheet with PCB footprint and material spec.
You can fit 5 Thonkiconn jacks in the same space as 4.5 Erthenvar jacks.
Comparison with Kobiconn part.
We are now offering a PCB/Panel set and Enclosure for this project. These items are all manufactured with the blessing and support of Mutable Instruments. For the PCBs we use same PCB manufacturer as Mutable Instruments, to the same specifications and finish.
Full information on the this unit is here.
NOTE: neither Thonk or Mutable Instruments provide formal build or part sourcing support for this project. This is NOT a beginners project. There is a thread on Muffwiggler for community support here, and on the Mutable Instruments community forum here.
Please read the important information below about the display lens and BOM considerations
DISPLAY LENS INFORMATION: If you have an existing tester build you will most likely need to
remove the display Lens in the Aluminium panel first. In order to fit the display behind the lens you must use a display which does not protrude further than XX mm from the surface of the PCB, these are readily available on eBay. The display part number recommended in the official Mutable BOM will not fit behind the lens as you won’t have enough thread on the PJ301BM jacks, in this case you need to remove the lens before fitting your completed tester PCB into the case. We also recommend that you solder the PJ301BM minijacks LAST when using the lens. Solder everything other than the jacks, put the jacks into place but DO NOT SOLDER yet, attach the panel and fit the nuts to the jacks. Make sure the jacks are aligned and then solder. They will be lifting up from the surface of the PCB slightly but they do work.
ENCODER INFORMATION: The part specced in the official Mutable BOM has a shaft length that 
extends 20 mm from the PCB surface, when using the Aluminium panel with the Lens the shaft extends 5mm from the panel, this is just about workable but Ideally an encoder which extends 25mm from the PCB surface would be better.
The example below is of the original Mutable enclosure with Acrylic front panel. We have maintained exactly the same design but added an Aluminium front panel.
Several problems werefaced during the development of the Mutable Instruments Eurorack modules, the module tester solves these.

Known commonly as ‘Flight of Harmony’ or ‘Erthenvar’ jacks, this popular component is a vertical mount 3.5mm switching phone jack with a threaded metal bushing.
This is the latest version of the part, redeveloped by the manufacturer in November 2012 to provide very reliable switch contacting.
Material:PBT housing, beryllium copper spring, brass curve piece.
The PJ302M is a horizontal or right angled mount 3.5mm switching mono phone jack.
It can simply be converted to a non switching jack as shown below. Various euro modules use these jacks, including the 4ms RCD and SCM modules.
All materials used are RoHS compliant.

These transistor pairs are matched using the well-respected Ian Fritz Method.
They are Vbe matched to be within 2mV or less of each other.
These transistors are suitable for the TTSH project, which states:
It’s a good idea to match all the transistor pairs before starting with everything else. You’ll need 9 pairs of matched 2n3904. And 5 pairs of 2n3906.

The C3 is the ‘standard’ Vactrol to use in a Buchla LPG, the C4 is a really nice contrast with a longer tail and often more saturated sound due to the longer sustain.
Excelitas Vactrol analogue optoisolators have an LED as the input element and a photoconductive cell as the output element, the coupled pair acts as an electrically variable potentiometer. These are the parts previously known under the brand name VACTEC, as manufactured by Perkin Elmer.
These standard 16mm pots have solder lugs for easy panel wiring.
Shaft Diameter – 6.35mm (0.25″)
Shaft Length – 15mm (0.59″)
These PT range knobs are made in the USA by Rogan, they are not official Mutable Instruments or Make Noise products, but are the same style from the same factory.
Refer to the Rogan data sheet Rogan to check dimensions and other information.
Please NOTE: You remove existing knobs from your modules at your own risk, don’t force them! Also please check what shaft types you need first BEFORE ordering. Module manufacturers do not always consistently use a certain shaft type, they may change between D or T18 for example.

Taking Knob DIY to the next level!
These are the same brass inserts with M3 setscrew that you find inside our high quality Davies 1900h clone knobs. They are designed for a 6.4mm pot shaft.
You can use these to make one-off or small runs of knobs out of any material you like. Wood, Sugru, 3D Printed… it’s up to you.
You could also just use them as small knobs if you like how they look. Note the screw does extend outside the body of the insert when fully tightened on a pot shaft.

The Black (D) part has been specially manufactured to fit correctly on new style Make Noise modules. The Rogan knobs on Make Noise modules have a round hole for around 7mm of the knob shaft before it turns to a D shaft. This means that other manufacturers D shaft 1900h clones will sit no closer than 7mm off the surface of a Make Noise panel. Note the pointer orientation on these means they are not suitable for all D-Shaft pots, see diagram below, the pointer is on the curved side of the D.
The Synth Pointer style will be very familiar to fans of Synth Tech, Pittsburgh Modular, Rebel Tech and L-1 modules. They have a 6.4mm / 0.25″ shaft with setscrew and the same sturdy brass insert as the 1900h clones.
The ‘small’ knob was previously referred to as the ‘SynthTech’ style knob.
All PCB sets include the Micro SD Card slot component FREE
This is not a full kit, if you want a full kit go here.
This is the only hard to find component required for Radio Music. Note you still need to purchase an MicroSD card! The very cheap $1 type cards are not worth the trouble they will cause you, we highly recommend SanDisk MicroSD cards. Easily available from any camera or computer stores, eBay or Amazon etc.
Full project details and documentation here – http://github.com/TomWhitwell/RadioMusic/
NOTE – you need to purchase a MicroSD card and a Micro-B USB Cable elsewhere to set up this module. The Micro-B cables are the smallest type shipped with Kindles and many Android phones. You also need a card reader to write files to the SD card, many laptops and desktops already have them built in now. – Read the setup and build documentation here.

These are the exact knobs used on recent Intellijel modules. (Shapeshifter, Metropolis, Atlantis, SpringRay etc.)
They are manufactured by Sifam (in the US distributed by Selco).
Both sizes of knobs are available in 6mm D-Shaft and 6mm T18 shaft types.
The Cap comes separate from the pot body so the orientation of the pointer to the D-shaft can be set at any angle (e.g. you can choose either zero degrees or 180 degrees, which are both typical). The body and cap colours are an identical match to Intellijel colours.
These knobs are not an Intellijel product and are not sourced via Intellijel.
The panel shown below is the Cwejman RES-4 alternative panel from Grayscale.
A single KRL 1% C-2AQ Tempco resistor.
1K, 2K and 1.87K available.
1.87K is a replacement part for classic ARP synths including the 2600, four of these tempcos are used in the TTSH project.
One for each oscillator and one for the filter.

Shaft Length – 15mm (0.59″)
These are the pots that are included with 95% of all Thonk produced kits and specced by many manufacturers. These pots work great with all the 6.35mm round shaft knobs we sell.
These pots are perfect for Music Thing Modular, Synthrotek, RYO, Manhattan Analog, Fonitronik, Frequency Central (FCUK) & HexInverter projects where 9mm pots are specced… but do double check as there are a few exceptions. They are not the first choice for panel-wiring… but we do have Pot Chicklets coming soon to redress that balance!
We love these pots, they feel smooth and precise and have got a strong following for a good reason. One thing that always annoyed us was that annoying little anti-rotation tag that you have to cut or break off, so unlike other distributors we got them manufactured without that tag. Also removing the nut and washer on each pot to build something like a 64 pot sequencer panel can get REALLY tedious, so again unlike other distributors we include the nut and washer bagged separately. It only save 20 seconds per pot maybe, but it adds up!
