Erica Synths Extends its DIY Lineup with EDU DIY BBD
New DIY module reverse engineers the architecture of a classic bucket brigade delay
Riga, Latvia, October 17, 2024 — Erica Synths announces the latest module in its mki x es.EDU series: the EDU DIY BBD. The new DIY module, available now and priced at €70, offers simple circuit design with classic BBD effects, and includes a thorough step-by-step walkthrough of the entire circuit design process.
Before digital advancements simplified sound processing, engineers tackled delays using bulky tape echo machines or natural echoes from reflective surfaces. In the late 1960s, engineers Sangster and Teer innovated with the bucket brigade delay (BBD), a system that splits audio into samples passed through a transistor-capacitor chain.
This method mimics how sound travels, delaying the output signal relative to the input. Over the course of building this module, DIYers will reverse engineer the architecture of a classic bucket brigade delay, recreating a bare bones version on the breadboard - and then use a proper BBD chip to implement a simple audio delay effect.
Erica Synths and Moritz Klein developed the mki x es EDU series of educational DIY kits with one specific goal in mind: to teach people with little-to-no prior experience how to design analog synthesizer circuits from scratch. Rather than just soldering and racking, these kits were mean to take users through the entire circuit design process step by step, explaining the rationale behind every circuit design choice and and how it impacts the finished module.
Each mki x es.EDU kit is simple and is comes with extensive user manuals which can be downloaded separately — this is in lieu of customer support in case your DIY build fails to function or similar.
The mki x es.EDU BBD is available now in the Erica Synths Shop and priced €65. For more information, please visit the Erica Synths site.
