Message-ID: Hey all, Where do you think would be the cheapest way for me to get some time in a rapid-prototyping facility with a 3d printer? It's for a small job, probably fewer than 10 pieces (each one about 2 cubic inches of material). I figure I might be better off finding something local; even if the parts themselves cost more, it'll be cheaper without shipping costs. Personal anecdotes regarding the quality and reliability of any printers you know would be super keen.

It's a custom-shaped part for a Rubik's Revenge. Precision isn't too necessary and I know from past experience that the extruded plastic is strong enough for the job. 2009/4/7 john arclight > What material do you want?

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. http://machineproject.com/events/2009/05/03/diy-digital-sampler-design/ 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. http://machineproject.com/classworkshop/2009/05/02/basic-electronics-may09/ 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. http://machineproject.com/classworkshop/2009/04/11/command-line/ From arclight at gmail.com Thu Apr 30 15:11:22 2009 From: arclight at gmail.com (john arclight) Date: Thu Apr 30 15:11:36 2009 Subject: [dorkbotsocal-blabber] Machine Project events for May In-Reply-To: <2fd1fa350904291544q9d8f03bk600badcef6f6a2bb@mail.gmail.com> References: <2fd1fa350904291544q9d8f03bk600badcef6f6a2bb@mail.gmail.com> Message-ID: <769756f50904301211k78e98149h4580ca4f8433a5df@mail.gmail.com> Speaking of events, the LayerOne hacker conference is coming up soon. When: May 23-24 2009 Where: Anaheim Marriott (near D-Land) Link: http://layerone.info Also, there's going to be an after party at the 23b Shop on Sunday. So everyone, feel free to bring your projects and show up! http://hackerspaces.org/wiki/23b_Shop Arclight On Wed, Apr 29, 2009 at 3:44 PM, Thomas Edwards wrote: > 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?.
