Green modular, part 5: Behind the scenes

In this final part to the green modular series I'll talk about environmental and related issues associated with the modular business, going beyond the manufacturing of the modules themselves. We began this series with RoHS and there may be a temp…

Green modular, part 4: Wood, and toxic waste

In this part of the Green Modular series, I'd like to talk about wood, and toxic waste. Part 1 focused mostly on saving energy; in parts 2 and 3 I wrote about metals, and some of the environmental issues related to metals are caused by their toxi…

Green modular, part 3: More metal

The RoHS "big three" metals I talked about last time occupy a lot of attention of synthesizer manufacturers because we have specific legal obligations we must meet regarding those metals; but many other metals are also used in building synths, a…

Green modular, part 2: the big three metals of RoHS

In this second part of the series on modular and the environment, I'm going to look at metals. Modular synthesizers are made of many different materials including wood, plastic, and glass, but a significant part of the mass of a synth (or any ele…

Exponential converters and how they work

Exponential converters are basic building blocks used in many synth circuits, but for many of us, they are incomprehensible black boxes.  The basic concept of how an exponential converter works is very simple; but the simplest possible circuit f…

Level up on circuit simplification

In my last entry I talked about the rules for simplifying series and parallel circuits. Two resistors in series can be replaced by one with a value equivalent to the pair of them; two in parallel can similarly be replaced; there are other rules in…

Combining components for new values

When I started breadboarding the Coiler VCF (see my new videos about it...), I ran into a problem: the design called for a couple of 6800pF (also known as 6.8nF) capacitors, and I didn't have any of those on hand. I didn't want to rush out and bu…
