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.

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.

NERP is not exclusively raspberry pi, the small computer interest group atPumping Station:One in Chicago.

Find NERP and Pumping Station:One
at http://www.meetup.com/NERP-Not-Exclusively-Raspberry-Pi/

NERP meets at 7pm 6-17-13 at Pumping Station:One, 3519 N. Elston Ave. in Chicago.
Doors open at 6:30pm. NERP is free and open to the public.

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)

Conductive Paint Workshop: Wednesday @ 7pm

Good news! Instructables have started sponsoring monthly build nights. And the more tutorials we make, the more supplies and equipment they’ll send us.

This month, we received a whole bunch of Bare Conductive Paint Pens. Tomorrow night at 7pm, we’ll spend a few hours playing around with them. Come experiment with the wonders and dangers of paper circuitry!

CNC Build Club – ShapeOko Night

shapeoko

This Thursday at 7:00pm  Edward Ford will be hosting a ShapeOko night.  Edward can help you build, complete, setup and use the ShapeOko router.

He will also give a quick overview of the web based MakerCAM program.  MakerCAM can be used to create toolpaths for CNC routers.  Edward and Inventables are working to develop this program into a full featured CAM program.

MakerCAM

For those without ShapeOkos, we can talk about your CNC project or work with some of the digital fabrication equipment at PS:One like the laser cutter, CNC router or 3D printers.

Please RSVP via Meetup.com.

Bitbeam Presentation – CNC Build Club

Bitbeam

This week we have a presentation by Jason Huggins (@hugs) on Bitbeam and the Tapster robot he built with it.

jason-huggins-with-tapster

When:

Thursday, May 9th @ 7:00pm, upstairs in the electronics area

Topic:

Jason will give an overview of Tapster, his open source, 3D printable, mobile app testing robot. In addition to explaining why creating a mobile testing robot is not the worst idea you’ve ever heard of, Jason will give an overview of Bitbeam, the open source building toy that he developed, which Tapster’s made out of. He’ll cover his making journey as he’s experimented with laser cutters, CNC mills, and 3D printers to make Bitbeam. For fun, the talk will also include live demos of Tapster playing Angry Birds.

About Jason:

Jason Huggins is CTO and co-founder of Sauce Labs, a software test infrastructure company, and is the original creator of Selenium, a popular open source web testing tool. In 2011, for an art project he was working on, Jason created Bitbeam – a 3D printable LEGO-Technic-compatible construction toy. Jason lives in Oak Park, Illinois.

CNC Stuff

Following the presentation we will break away to work on various CNC projects. The ongoing group project continues to be the mid-sized CNC Router. The machine is now fully functional under Mach3 control. We can talk about the Mach3 setup and cut a few things.
