CNC Build Club: Shapeoko 2 Demo

Shapeoko

 

At the next CNC Build Club, on Thursday 10/24/2013 at 7:00pm, we are going to have a demo of the, soon to be released, Shapeoko 2 CNC router.  The ShapeOko was designed by local inventor, and PS:One friend, Edward Ford.  The original version was extremely popular.  The new version adds many new features.

  • Larger work area.
  • Easier to expand
  • Open front and rear for feeding stock through
  • Dual motor Y axis is now standard
  • More ridged
  • Belts lay flat and are easier to install

NERP: Implementing MIL-STD-1553 with 3 Beagles

Tonight Trefor Delve will present a distributed simulation development making use of three Beagle Bone Blacks as part of the network. The simulation is used as a proof of concept for a general purpose, configurable simulation platform making using of public domain software.

The presentation will introduce the principles of the MIL Standard 1553 data bus, show a simulation with simulated hardware and demonstrate the same software running on distributed Beagle computers making use of the Beagle’s ADC, PWM and SPI interfaces.

The presentation will also demonstrate the use of the QT widget set to allow remote virtual hardware to interact with the Beagle simulation.

The presentation will demonstrate the setup of the ADC, PWM and SPI interfaces using the system capabilities.

Frank Hammer Genetics & Epigenetics talk tonight!

Frank Hammer, a retired scientist from Monsanto, will be giving a talk tonight on Genetics and Epigenetics. The session is divided into two parts:

1st Discussion

1. General genetics, which would include the structure of DNA,
2. How the four bases or nucleotides, adenine, thymine, guanine and cytosine are paired,
3. What is a gene,
4. What is messenger RNA (mRNA)
5. How mRNA codes for proteins,
6. What is a codon,
7. How proteins are manufactured in the ribosome,
8. Answering questions.

2nd Discussion

1. The polymerase chain reaction (PCR), which is how we multiply DNA millions of times so it can be forensically and biologically analyzed,
2. Epigenetics, its causes and effects,
3. Answering questions.

Frank’s Bio

Frank has been involved in the life sciences for about sixty years. Has written two book chapters, many reports, including one about antisense which was published by Frost & Sullivan. Frank has eight patents, in the fields of food technology and diagnostic biochemistry. His avocations are reading and writing poetry.

And that’s all Frank wants to say about himself… Find out more at the meeting :)

See you all soon!

CNC Build Club – Gonzo Build with Moto!

Make With Moto

We have a very special event planned for the next CNC Build Club meeting on Thursday, July  18th.  We are going to do a Gonzo Build with the Make With Moto crew.  Make With Moto is a Velcro covered Sprinter van filled with making equipment that is touring the country.  In addition to the making equipment they have a bunch of unlocked and hacked Android smartphones.  They have been doing hack-a-thons around the country.

BL9LF5vCQAIlv6F

We thought it would be awesome to do something that combines our CNC hacking skills with their  phone hacking skills.  We would temporarily remove the “a-thon” and do a one night Gonzo build.

The plan is to do a digitally controlled camera slider.  The phone would replace the camera and control the motion.  We are still seeing what is feasible on the phone control options, but ideally you could control the phone from a second phone and view live video or snap shots from the slider phone.

It will probably look similar to this camera slider that was done in the past, but it will have a mount for a camera and have all the drivers on the slider.

Inventables will be supplying all the CNC materials.  As the details get more firmed up, I will edit this post so check back later.  If you have any other ideas, let me (Bart) know.  We may be able to get materials for multiple versions.

Programming in Erlang -plus- Making an Xbox Media Center on the Raspberry Pi

Tonight at NERP, we’ll have two presentations.

Brian Chamberlan will tell us about using Erlang to program/control the RaspberryPI/BeagleBone. Erlang is a functional, general-purpose concurrent, programming language and runtime system. Erlang provides language-level features for creating and managing processes with the aim of simplifying concurrent programming. Processes communicate using message passing instead of shared variables, which removes the need for locks. [paraphrased from wikipedia]

Michael Beck will show us how to set up Xbox Media Center, XBMC on the Raspberry Pi. Pretty much every possible mode of interacting with a digital media stream is supported by XBMC. The Raspberry Pi’s excellent (but proprietary) video rendering hardware makes it an ideal platform for building a home media center.

CNC Build Club – Gonzo Build #2

One Axis Drawing Machine

This week the CNC Build Club is going to attempt Gonzo Build #2.  A gonzo build is where we try to knock out a complete CNC project in one night.  Gonzo build #1 was the Quantum Delta 3D printer.

This week we are going to build a one axis 2D drawing machine.  This uses two independently controlled carriages on the same axis to get 2D motion at the ends of the linkages.  The purpose is only to have a little fun and to cut our teeth on a simple inverse kinematics machine before moving onto a much more complex 6 axis machine.

If you want to help, please join us.  The meeting is open to non members.  Please RSVP via meetup.

ABS Smoothing – CNC Build Club

ABS Smoothing

Last night’s meeting was great.

  • A huge turn out of about 25-30 people
  • About 8 people certified on the laser by Colin
  • About 4 people certified on the vinyl cutter by me.  I started adding tips to the wiki page for the vinyl cutter because there was a little struggling to get good results.  I think it was due to not setting the orientation of the plot (worked for me)
  • I saw some certification on the LulzBot.  We need the linux computer for that fixed or replaced!
  • Ryan and Liz Certified on the CNC router and they cut a complete project on their own (cool little circle/star thing)
  • Acetone Smoothing….So it appears to make good prints look great and bad prints to worse.  You can’t polish a turd.
  • The Quantum Delta was slowly cranking out angry ducks and squirrels all night.

ABS Smoothing

ABS Smoothing

We did some experimenting with ABS Smoothing.  Donald J brought in most of the equipment which consisted of a heating pad, glass cookie jar and a little stand to put the parts on.   We put a small amount of acetone in the jar, then put 3D printed ABS parts on the stand.  When the acetone heats up it forms a cloud in the bottom of the jar, enveloping the ABS part.  Most of the acetone condenses back near the top of the jar.

It worked pretty well on finely layered parts.  It made some parts actually look little worse by highlighting flaws.   It took quite a while to heat up and could be optimized.  Donald is looking for volunteer ABS parts to practice with.

We have a temperature controller for it we can wire up.  It can only drive about 3amp @ 110V.  Does anyone have an SSR?  The mechanical relay probably won’t last long in this application.  The heater is probably 5-7 amps (guess)
