• Tweak five potentiometers to set up another voltage output from the Turing Machine. This can be a different melodic sequence, related to but different from the main output.• This is a simple, low-parts count, low-current expander for the Turing Machine Random Sequencer in 4HP. It connects around the back with a 16-way ribbon cable and works with any Turing Machine (Mk2, or Mk1 with the backpack).• It acts like a variable 5-bit digital-to-analog converter, taking 5 bits from the Turing Machine GATES expansion port, running them through five potentiometers and giving one summed voltage output.• Multiple Volts expanders can be daisychained from one Turing sequencer to give melodically different outputs that are all related to (and change with) the main Turing sequence.• You can try out a fully operational Turing Machine + Pulses + Volts in the free VCV Rack software.• Volts is a shrunken version of the original Voltages expander, and was designed in one day while on holiday in Cornwall.• Volts is a very straightforward through-hole DIY build, that would be a good first DIY project. If you get stuck, the Volts Github Issue List or the main Turing Machine issue list are probably the best places to start, although very few people have ever had difficulty with this module.• Multiple VOLTS modules can be daisy-chained on a single Turing Machine to give a ‘polyphonic’ CV output.DIY-Kit-Type:THT-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. Only trough-hole parts to solder. Make sure to check the build guide before you buy.

Workshop Computer is a programmable Eurorack music computer from Music Thing Modular, designed to transform instantly through hot-swappable program cards. Inspired by early computer music studios such as EMS and Bell Labs, it brings algorithmic sequencing, audio effects, MIDI utilities and experimental sound generation into a compact 8HP module.The module ships with Reverb+, Turing Machine and Simple MIDI program cards, plus four blank cards ready to load with new programs from the growing open-source community library. Program cards can be swapped to completely change the module’s function, turning Workshop Computer into a stereo reverb, random looping sequencer, USB MIDI interface, utility processor or something entirely new.Workshop Computer features dedicated Audio/CV, pulse and precision CV inputs and outputs, three hands-on controls, a 3-way ON/OFF/MOMENTARY switch and six LEDs for clear visual feedback. The DIY build is approachable, with all surface-mount components pre-soldered; builders only need to install the pots, switches, sockets and LEDs.Powered by the RP2040 microcontroller, the same chip used in Raspberry Pi Pico, Workshop Computer is also open to coders and developers. Custom programs can be written in C/C++, Arduino Pico, CircuitPython, Lua and other RP2040-compatible environments, then loaded or updated via USB drag-and-drop. Compact, flexible and deeply expandable, Workshop Computer is a creative platform for effects, sequencing, MIDI, modulation and experimental Eurorack programming.Features• Programmable Eurorack music computer in 8HP.• Hot-swappable program cards for instant function changes.• Includes Reverb+, Turing Machine, Simple MIDI and 4 blank cards.• Growing free library of community-made program cards.• Audio/CV, pulse and precision CV inputs and outputs.• Three knobs, 3-way switch and six LED indicators.• RP2040-based platform compatible with C/C++, Arduino Pico, CircuitPython and Lua.• USB drag-and-drop program card updates.• Full DIY kit with SMD components pre-soldered.• 25mm depth and 175mA power consumption.DIY-Kit-Type:SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. All SMD parts are pre-soldered, only trough-hole parts to solder.

The Workshop System is a complete modular synthesizer and audio computer – small enough to fit in a book-sized case, but packed with sound-shaping tools and educational potential. Designed for musicians, makers and tinkerers, it’s a fully modular playground for learning, composing, experimenting, and hacking.The system includes 14 analog and digital modules, ranging from vintage-style oscillators and filters to a programmable digital Computer module with swappable program cards. It works standalone inside its custom case or can be mounted in a Eurorack system (42 HP).You can use the system for crafting pure tones, exploring feedback loops, integrating guitar pedals, or writing your own firmware – the Workshop System invites hands-on discovery and creative exploration.Features:• Complete modular synth in a compact, case-mounted 42HP format• Includes 14 modules: oscillators, filters, mixer, ring mod, stompbox loop, envelope generators, and more• Powerful Computer module with RP2040 brain and reprogrammable program cards• Runs on USB-C (Power Delivery!) power (15 V) or standard Eurorack barrel input (15-25 V DC)• Works with audio sources, guitar pedals, microphones, and external MIDI/CV gear• Designed for experimentation, hacking, education – and serious music making The kit does not include:• Eurorack patch cables – we figure that many users of modular synths already have patch cables lying around – but if you’re just starting out and would like a set of short patch cables then we have a cable set available HERE• A power cable – The Workshop System has two power options: The easiest way is via USB-C PD power, but you can also use a regular 15-25 V DC barrel connection like THIS. The system will happily run from battery powerbanks and laptop adaptors. We feel that there are already enough USB-C cables in the world.DIY-Kit-Type:SMD-Kit-1.
