Honest / interesting review of 15 years of building a business.

About the best code samples I've seen: simple, to the point, and beginning to wrap my head around the architecture of these things.

Tom Wiltshire on various classic oscillator designs based around the Curtis 3340.

Good writeup on the LM386, and the fact the basic application note is garbage. (This solves many noise issues I had years ago).

James is keeping weeknotes on designing a product based around an EFM32 microcontroller – I enjoyed this first installment; it's nice to see how other people think about projects.

"In time I wasn’t plugging in my newly arrived modules so quickly. I was spending more time looking at them, admiring their structures, noting aspects unique to various individual companies. Some modules have lovely design flourishes, bits of fantastic line art right there on the circuit board, so enticing it threatens to give “cyberpunk” a good name all over again. Others have funny little phrases, puns on functionality, like where the power supply goes, or little axioms that both gently mock and encourage the beholder—Barbara Kruger by way of circuitry. This is what I now first look for when I unpack a new module." Really nice Marc Weidenbaum piece on the aesthetics and semantics of circuit-board design.

ATmega / DAC based envelope generator. Filed for reference.

A better normalize-text ULP.

A really nice exploration of what live piano + electronics could be like. I'm not quite sure how I feel about the actual filming: there's a lot of modular on display, which is very analogue and visible, with all its sequencers… but there's also at least one midi controller visible and if it's talking to a computer… is it disingenuous to hide a laptop? Hmn.

Well this looks very good.
