  • Saturday, from 02:00PM Triangle Embedded Computing Hack Afternoon (TriEmbed):

    Triangle Embedded Computing Interest Group (TriEmbed)

    It’s time again for another Hack Afternoon at SplatSpace!

    What is an Arduino? What is a Raspberry Pi?  See these links for more info:
    </a><a href=”http://arduino.cc/” target=”_blank”>http://arduino.cc/
    http://raspberrypi.org/

    No prior experience is required to attend hack afternoon and you don’t even need to own an Arduino. There are plenty of members who will be glad to let you look over their shoulder and ask questions. Some will even hand you some parts and let you tinker. If you have your own parts, definitely bring them. We have lots of space and everyone should have room to work on a reasonably sized project.

    You don’t need to be a member of SplatSpace in order to attend, but please do ask about the membership options while you’re there. It’s a great group of folks and, if you’re into embedded computing there’s a good chance that you’ll share interests with other attendees.

    Go here for directions to SplatSpace: http://splatspace.org/location/

    If anyone has projects they’d like to collaborate on, feel free to start a conversation on the http://mail.triembed.org/mailman/listinfo/triembed_triembed.org mailing list. This announcement has also been cross-posted to that list.

    We hope to see you there!

  • Sunday, from 06:00PM Craft Project Night:

Meetup to WordPress Poster

September 12th, 2014   

If you follow our blog a lot, you may have noticed that for the last few months the weekly schedule post has a) been more reliably on time and b) been pretty regularly formatted.

Creating the weekly schedule post used to be a very manual task, requiring someone to go through the meetup listings and write the entire post by hand. This was error-prone, time consuming, and on more than one occasion resulted in late or no schedule being posted. That really sucked for people who were interested in events that occurred early in the week.

There’s no good reason for this. Meetup has a well developed API, and our blog runs on wordpress which has a great API too.

To that end we automated it: for the last couple months the schedule has been posted with mwp, a meetup-to-wordpress crossposter designed to post the coming week’s schedule to a wordpress blog.

We figure there’s a chance other people might have the same use case, so we invite you to give it a try, file issues against it, and contribute code to it. Happy hacking.

Member Project – Building Guitar Humbuckers

September 6th, 2014   

Over the past couple of months, member Jeffrey Crews has been slowly refurbishing an old Gibson Epiphone guitar that showed up at the Space.

“It was missing the pickups, nut, mounting plate for the output jack, all wiring, and rear electronics cover.

However, the body was in ok condition and the neck was straight. Since I had rebuilt a Fender-style electric guitar in the (distant) past, and recently rebuilt an electric bass, I decided to fix up this one, only this time with a minimum of purchased parts.

I had to purchase the bridge and tailpiece (to which the strings attach) from Ebay for $20 because my machining skills are nowhere near up to that challenge. I designed and printed the electronics cover, nut, knobs, and jack mounting plate.

I also decided to take the plunge and build a set of 2 “Humbucker” pickups instead of buying them.

A little background: a guitar pickup uses a coil of thousands of windings of very fine wire on a plastic “bobbin,” on which are also mounted strong magnets. The steel strings, which are also in the circuit, vibrate when plucked, and this vibration causes a fluctuation in what would otherwise be a stable magnetic field. The coil turns this fluctuating magnetic field into an electrical signal.

The coil might also pick up the 60Hz signal that all of our electrical systems are continuously broadcasting; a “Humbucker” pickup uses two paired coils that are wound oppositely to each other so that the two 60 Hz signals will be out of phase and cancel each other out. The magnets on the two coils are also reversed in polarity, so that the actual “string” signals from the two bobbins are NOT out of phase.

The above is a very, very simplified and fudged explanation; pickups are something of a Dark Art and there’s way more information on the Internet that you’d ever want to read about them.

Splatspace has a 3D printer and also some large coils of fine (~45 ga) enameled wire, so I designed and printed 4 bobbins and a jig to hold the bobbins in an electric drill. I used a small clamp to precisely adjust the drill’s speed so that I didn’t snap the wire.

First I re-wound small spools of wire from the giant 10 pound reel

then wound each bobbin.

Gif of winding bobbin with power drill

I didn’t count the windings; some of the original Gibson technicians said that they used “as many as it would hold,” so I didn’t sweat it. Pickups have to be “potted”- infiltrated with wax or plastic so that the coil windings themselves don’t vibrate or move around. Since I printed these bobbins in ABS, I just trickled ABS glue (ABS dissolved in acetone) into the windings until they felt hard.

Humbucker #1 uses common rare earth magnets I bought from Banggood.

The 6 “slugs” which penetrate through the bobbin are just pieces of steel bolts.

Humbucker #2 will use strong ceramic magnets. Hopefully these two completed Humbuckers will have somewhat different characteristics so that the usual pickup-selector switch can select for different sounds.

Here’s the first completed bobbin.

Since then I have completed the second bobbin, and assembled and tested the first completed Humbucker. It works!

Up next: printing out the casing which will hold the completed Humbucker and allow for spring-mounting inside the body. I might also print out a thin pickup cover for each pickup since they’re kind of ugly. This style of guitar didn’t originally have a pickguard, but I might cut one out of brass sheet and electrolytically etch it. More on that later.”

DIY Laptop Stickers

September 3rd, 2014   

We recently got a new vinyl cutter at Splatspace, which has let members start making their own vinyl decals. One of our members is a huge comics fan, and used our vinyl cutter to make a new sticker from art for a not-yet released comic:

This was an easy image to turn into a decal at Splatspace. As the member explain’s:

Using Inkcut, a plugin for Inkscape, another member at Splatspace helped me create the sticker and cut it out of white vinyl. It was a pretty good sample project, because the design is super simple and blocky.

The cutter, a Roland Vinyl Cutter, actually functions as a printer; you process an image in Inkscape to reduce it to just the lines you want, and then use Inkcut to send it as a print file to the cutter. It’s a really simple process.

And here’s the final product:

Non Compliant

Interested in making your own stickers for your computer, or other decals? Come to a meeting, and learn about using the vinyl cutter!

    PLEASE NOTE THE DATE CHANGE


    Following the TriLUG seminar on the BASH shell on Sept. 6, let’s gather and spend some time practicing what we learned!

    This “bash bashing” is happening at Splat*Space in Durham, Sat. Aug 30 at 1pm – 4pm.

    All persons are welcome to attend, and wired & wireless networking and power available.  Plenty of mentors will be around, and some small demonstrations will be presented of the material gone over at the meeting, an FAQ session will be presented, and other questions answered.  Please bring your device with bash installed — including MS-Windows boxes with cygwin installed.


    Splat*Space is located at 331 W. Main Street in Downtown Durham — there is a front and back entrance. We recommend you go onto Ramseur St. and enter through the back, using the parking in the back.  Signs will be posted in the glass door of the red-brick building with cement horizontal strips and window sills (the historic Snow Building).  Splat*Space is in the basement — call for someone to let you in.


    Feel free to inquire about Splat*Space and other activities there, but please be respectful of the materials and personal property in the ‘space.

    Looking forward to seeing you there.

  • Sunday, from 06:00PM Software Project Night:

    Come to Software Project Night with a project that you want to show off, you want to ask others for help with, or that you just want to work on.

    Come to Software Project Night with a software topic you want to talk about because you think it’s cool, or you want to understand it better.

    Come to Software Project Night if you’re a beginner or an expert programmer: sharing your unique perspective on software is what makes Software Project Night work!

We hope to see you out!
