uh... yeah, what he said...
first, welcome to all, make yourselves at home. glad to be yr 'umble
servant here, and thrilled to have an opportunity to support the
community in some way.
um... liminal... i read a great levi strauss essay on that...
something about lentils and lintels and beans and doorways... i'm a
big fan of beans. i probably still have the book up in the attic...
speaking of which, yes: multiplicity & focus. first order of bidness
here was to address some concerns about code written for the PSIM...
GPL licenses, open source, blah blah blah. the files section is set
up for you to post your own code to... feel free to share your
creation, and please respect the individual author's wishes (whatever
they may be) if you use or modify their code. discussion of
programs "in process" is on-topic, for sure.
next on the agenda, a home for the development and programming of a
diy "next generation" module along the lines of the PSIM... immediate
goal is an open-source hardware design (schematic, layout, gerbers,
panels). there's already been some discussion on SDIY, and a
tentative consensus (i think) to stay in the CV rather than Audio
range and aim for some backward-compatibility with existing PSIM
code. that will continue to unfold in the next few weeks, i'm
thinkin'...
and then. more is better. audio modules, single-purpose modules,
modules with basil/peanut pesto... yum. the possibilities are indeed
endless. from my perspective, i think there's value in a series of
projects which actually get completed... as compared to endless
iterations of plans, each one grander than the last, none of which
get off the drawing board. and for once i'm speaking from experience
on this. but striking that balance between dreaming & doing is up to
you.
again, welcome
