Blue Lantern Modules is a Phoenix, Arizona-based manufacturer of handmade modular synthesizer modules, founded by Flavio Mireles. What began as an electronics hobby in 2002 evolved into a full-fledged business producing Eurorack modules starting in 2009. All modules are assembled and distributed entirely in the United States.

The company offers a wide range of Eurorack modules spanning oscillators, filters, envelope generators, percussion modules, LFOs, MIDI conversion, and utility modules. Blue Lantern is well known for its analog filters, including the versatile Asteroid Operator and the compact Steiner 10 6hp VCF diode filter, as well as distinctive designs like the Phobos Lunar PLL LFO, the Subharmonics Generator, and the Lunar Modulation Center — a VCO station with Buchla-inspired elements. Other popular modules include the Macro VCO, CMOS Party 4hp Logic module, Simple ADSR, and the Ergot Organic Synthesizer (EOS).

Blue Lantern has built a reputation in the modular synth community for offering competitively priced, unique modules with a DIY spirit. The company has expanded beyond Eurorack into the 5U/MU format, offering modules like the Yarns MIDI-to-CV converter and an eight-waveform analog VCO. Their modules are carried by retailers including Perfect Circuit and are available through their own online store and Reverb shop.
