CNC Router

After a long period without a CNC router (the very generous loan of our old one came to an end), we finally have one again! After a lot of toing and froing have opted for a OX CNC machine from Ooznest who did us an amazing deal. Although the main motivation was that it is solid build based on a open design, with a reasonably large working area. The capabilities are detailed below.

  • Working area, 1320 x 1275 x 65mm
  • Spindle, Dewalt 26200
  • Spindle speed, 16000 to 27000
  • Material, MDF, PLY, Timber, Plastic and non ferrous metals.

As always we couldn’t leave it as it came. We have already built a custom stand, which is really a necessity for a machine of this size and 3D printed a dust collection shoe. Future improvements will include

  • Limit Switches
  • Emergency stop
  • Connecting the dust shoe to the shop vac.

Once these are completed we will be making the machine available to the members upon them completing a training coarse.

Artemis 1 – Getting a Closer Look at Totality

Some fellow hackers and makers (and former PS:One members) shared an exciting project with us and we’d like to help them get the word out.

The Artemis 1 is on a mission to send a high altitude balloon into near-space on August, 21st, 2017 to film the total solar eclipse.  It’s a collaboration between the South Side Hacker Space and Chicago’s Remote Astronaut Crew.

 

 

The team is one of many participating in this NASA sponsored program, where launches all across the country will simultaneously capture video and still images of the eclipse from altitudes of 100,000 feet and more.  You can learn more about the program here:

http://eclipse.montana.edu

Artemis 1, like many before, is looking toward the sky for opportunities to teach, learn, and grow.  Leading by example through hands-on experimentation with measurable results is the best way to instill a passion for learning and a drive to reach higher.

 

Artemis 1 seeks your vital support on this campaign and the fundraising page can be found here:

Burlington Hacker Book Club!

We're excited to add a new event to the Lab's roster: the BTV Hacker Book Club! The group will be meeting monthly to discuss a book drawn from a list built by Lab members, with members voting on which book from the list to read each month. While Lab members pick the books, all who have read the book are welcome to the discussions, and attendees are welcome to bring munchies and beverages to share.

Our first pick is A Hacker Manifesto by media theorist McKenzie Wark, and we'll be gathering for the discussion on Thursday, 8/17 at 6pm in the Couch Room. For more details and updates, RSVP to the Facebook event.

We'll be discussing setting a recurring monthly date at the August meeting, and Lab members are presently voting on the September book pick. Cyberpunk classic Neuromancer by William Gibson currently holds a narrow lead, but there are a few more days for members to weigh in...

Shine on You Crazy KiCAD — and Other Tales from Chris Gammell

Chris GammellOn Monday July 17th, NERP will host Chris Gammell. Chris is an analog electrical engineer and product manager. He may be known to some of you as co-host of The Amp Hour, and as the charter member of Contextual Electronics. CE offers subscription based electronics courses with different levels of project-oriented learning and personal interaction with an instructor. The Amp Hour is a non-scripted off-the-cuff format show that usually airs every Thursday evening US time. It is the worlds largest and most respected electronics oriented radio show. Discussions range from hobbyist electronics to the state of the electronics industry, components, circuit design, and general on and off-topic rants.

At the NERP on Monday, Chris will present a free rendition of  the Contextual Electronics course titled Shine On You Crazy KiCad. NERP has talked about the open source electronic design program called KiCAD before, but this presentation is different. It’s designed for simplicity and fast execution to give a quick win for new users who follow along on their own laptops. The course is designed as an end-to-end art-to-part experience using KiCAD.  amphour logoWhen I say quick, I mean just 20 minutes start to finish to draw an electronic schematic and then translate the schematic into a printed circuit board PCB layout. (It’s possible to spend lots of days working on a complex circuit board design…) After that, the last step in the process will be for everybody who’s following along to pack up their KiCAD PCB layout files and send them off to OSH Park to actually be made into atoms and snail-mailed back to you. Chris’s demo board is a small, but useful add-on for a Raspberry Pi. The PCB is about 1″ square, so the cost at OSH Park is very small.

made with kicadEven if you don’t plan on actually making the circuit, go ahead and load up a copy of KiCAD  http://kicad-pcb.org/download/ so you can at least have a look and ask questions. It’s open source and free. Win, Mac, & Linux. Kicad is a pretty piece of software in my opinion, and I have a few good reasons for preferring it to Eagle (KiCAD’s freemium competitor).

Chris tells me there’s one thing that NERP might be able to help him with. Contextual Electronics is getting a new course for “absolute beginners” in electronics. This would be along the lines of “what do you need to know about electronics before even thinking of a course like CE”. When you first encounter a subject as broad and deep as electronics, it’s very hard to sort out the signal from the noise. You can spend a lot of effort on something that doesn’t matter while at the same time missing some small Rosetta stone or simple concept that’s perhaps in easy reach. conceptual electronics logoAfter we move past those first trembling steps, we can forget what it was like just building a knowledge framework. To make the best connections with absolute beginners, Chris wants to hear about your conceptual roadblocks or things you wish you’d known from long (or not so long) ago, and how they resolved (or didn’t resolve) themselves. I’m sure he’ll be happy to talk about it at NERP, but consider signing up for CE and visit the Building an absolute beginner course page and add your thoughts.

NERP is not exclusively Raspberry Pi, the small computer and embedded systems interest group at Pumping Station:One in Chicago. NERP meets every other Monday at 7pm at Pumping Station:One, 3519 N. Elston Ave. in Chicago. Find NERP and Pumping Station:One at

Sonder-OpenChaos am Samstag, 21. Mai: Revision Nachlese

Wie seit Jahren üblich traf sich die Demoszene zu Ostern wieder auf der Revision um sich in verschiedenen Wettbewerbskategorien zu messen. Wieder gibt es die besten Werke beim Sonder-OpenChaos zu sehen.

TOG Mid-Summer Open Social

Our June Open Social evening takes place on Saturday 17th May from 7PM. That’s about as close to the longest day of the year that we can manage! Dublin Maker is approaching fast too. Our members are starting to get a bit edgy. Drop in, poke them a bit, and ask them if they have their projects all ready to go 🙂

If you’ve never been to our Social, you’ll find it a great alternative Saturday evening in town. Come in and look around. If you’ve never been in before, we’ll give you the grand tour of the space. Talk to members and visitors about projects or things you’d like to do. If you like what you see, ask about joining as a full member. Hopefully there’ll be caint, ceol agus craic as usual. The space stays open until the last member is left……usually the small hours of Sunday morning.

Our Open Socials are always free to attend for both members and visitors alike. No need to book…. just turn up. You can drop in for 10 minutes, or stay the whole night. We have parking available. Bring beer, food, gadgets! Our doors are open from 7PM. Hope to see you there.

Milwaukee Vice!

This is our Post Vice at the Makerspace. It is a specialized type of vice used by blacksmiths. Designed to handle the abuse of clamping something very hot and heavy and allowing to to beat on it with a hammer. These are not really mass produced anymore, so when you outfit a forge you typically end up buying a used vice. Since these were so well built they basically last forever. Ours is somewhere around 100 to 150 years old.

Most of the dents you see were there when I bought the vice 4 years ago. However, the slices running near the top, left face are new damage, and go considerably deeper than the surrounding dents. I was concerned about the concentration of stress at those points and the potential for cracking the jaws. It was time for refurbishment and repair.

In this photo, 2 recent dents that were caused by someone missing with a heavy hammer. And you can see where the jaws of the vice have cracked away. The vice is constructed using some kind of iron, but due to the age, we’re not exactly sure what. The jaws style of construction indicates that they were forged, not cast. This is a good thing, it suggests they could be either steel (exact carbon content would be unknown) or wrought iron. It means it should be possible to weld new steel onto them! This is what we’re going to try to do.

We don’t know exactly what alloying elements are mixed into the iron, so it could weld smooth, or it could blow bubbles and burn up under the torch! No way to tell until you try, which is nerve wracking when the object in question is an antique. There are things you can do to tilt the odds in your favor. When welding, cleanliness is next to godliness. Much time was spent with a file and dremal to grind out every dent and crack, to clean and shiny metal. 

This is a shot after I finished welding up the slices. This is about the best result we could hope for. The welds are strong and clean, with only a few spots of porosity towards the face of the jaws. The way to fix the jaws is to deliberately weld on excess material and then grind them smooth again. They will be good as new.

After I finished welding almost all the spots, this is a shot of me filling in the missing corner of the front jaw. In this photo you can see that this is not the first time this vice has been repaired. Someone welded a new plate to the face of the back jaw, but the welds around the edges were quite corroded, so I ground them out to be filled in.

The front jaw is finished and ground, now all the welding is done on the back jaw.

And here are both jaws clean and ground. 

Such straight and sharp corners! Just waiting to get a new set of “beauty marks” in the service of our forge!
