Here are some Machine Project events for May that may be of interest
to Dorkbot SoCal members...

DIY Digital Sampler Design: The Good, The Bad, and the Crusty

Sunday, May 3rd, 2009 1pm

LECTURE DESCRIPTION: Circuitbenders and audiophiles alike have
dedicated buckets of time, sweat, and solder to the characterization
and creation of whatever it is they believe makes digitally stored
music sound “good”. This has led to some extremely focused work,
however, it has also led to weird fetishistic device-worship (see: the
Casio SK-1 or the world of tube DACs). In order to get back to the
fundamentals, Todd decided to design a sampler which intentionally
incorporated many of the audio imperfections which give samplers some
of their more noteworthy characteristics. The project started out as a
pedagogical tool for a talk he gave at the Bent Festival in 2008 — he
used it to demonstrate some principles of digital sampling (bit depth,
sample rate, dac architectures, memory types, etc) and drew parallels
between his little sampler and the likes of commercial products like
the SK-1, DL4, or MPC2000. It was, in part, also an invitation to the
audience to explore their own new design paths rather than keep
re-working old toys.


Basic Electronics Class

Instructor: Lewis Keller
Schedule: Saturdays May 2nd, 9th, 16th, and 23rd, 2-5pm

Course Description: Electronics is fun, useful, and fun. Electronics
for Artists covers both the theory and primarily techniques of working
with electronics. Students will be exposed to basic tools and
components for building robust, practical circuitry into their art
works. No attempt will be made to provide encyclopedic coverage of
electronics due to the sprawling nature of the topic — rather students
will be encouraged to become comfortable with experimentation and
hands on hacking.


The Command-line Ecosystem… hidden on your Mac

Sunday, May 10th, 2009 2pm-4pm
Taught by Gregory Whitescarver

Description:  A hands-on introduction to the command line,
specifically the Bash shell, which is present on all Macs (OSX only)
and tons of web servers. Gain comfort with basic tasks like navigating
directories, viewing and editing files, and logging into remote
servers. Users will create a small script that emails them the weather
forecast every day.
