Any Sub (dual self-powered sub oscillator)
This is a dual sub-oscillator unit (producing –1 octave and –2 octave signals × two). It can be used as a handheld device or as an 8 HP Eurorack module—in the latter format, you get a total of four sub-oscillators. Notably, these modules are self-powered by the waveform you feed into them, needing no conventional power supply. They utilize CMOS circuitry for their function.
I’d like volunteers to test this module in their setup before I release the schematic, production files, and BOM (Bill of Materials). I describe this as an EDI (Equitable DIY Initiative) module—it’s intended to be free, but I ask you to donate to Women’s Audio Mission and/or The Trevor Project if you build one. Commercial use requires donations proportionate to the number of modules sold. More details will be provided when the production files become available.
Feature List
- Dual sub-oscillator: output at –1 octave and –2 octaves, times two
- Configurable as handheld device or 8 HP Eurorack module (yielding four sub-oscillators in Eurorack)
- Self-powered—requires only the audio waveform as input, no external power needed
- Based on CMOS logic components (“CMOS magic”)
- Free to build, with donation-based ethical usage policy (EDI module)
Pricing
The page does not list any pricing or indicate that it’s sold commercially. It appears to be intended for DIY use, with no fixed price — instead, the creator requests donations to charitable organizations if you build one, and donations tied to commercial use if selling any modules.
Therefore, exact pricing in AUD, USD, EUR, or GBP is not provided, since this is not a product being sold but rather a DIY design with a donation-based ethos.
Release Date
The page does not provide a publication or release date for the Any Sub module. It appears to be a work-in-progress release, only offering a proof-of-concept video and images for initial testing, with schematics yet to come. No specific dates are mentioned.
