DMS Python Class 2

“This was a triumph…”

The second Python class had a large turnout today. We repeated our feat of packing the classroom.

Kudos to Daniel  Hosterman for a well orchestrated presentation.

The group is picking up momentum. Activities included defining strings in fancy ways, manipulating those strings with native Python functionality, and defining/throwing around new functions.

The group has a diverse mix of experience with people new to Python and coding in general, all the way to people who use Python daily in their career. The first hour of the class is lecture from Daniel, followed by individuals working / collaborating on their own projects.

Sundays at 3:00pm – All are welcome to join.

Guitar Stuff at Hive

031713150944

Last year, I purchased a 1970 Telecaster copy for $120 from Elderly Instruments. The frets were no good and much of the hardware was corroded, so it seemed like a good instrument to hone my repair skills on.

The first thing I did was take it to Hive and bounced ideas around with some folks. One thing I really love is that no matter what kind of project or idea you’ve got, there’s at least one or two people at an open house who have some expertise to share.

My cigar box slide guitar would’ve been cooler with frets.

So I decided to give all the hardware a good cleaning and replace the bridge saddles – they were pretty sharp and very uncomfortable to rest my right hand on while playing.  I also chose, somewhat foolishly, to refret the guitar when in fact a fret dress job was all that was needed. But if this was to be a learning project, I thought I should learn what I could. It also seemed like a big step towards building more of my own stringed instruments, which up until now have not had frets (such as my cigar box slide guitar).

I purchased some new saddles from the nice folks down the street at Bluebond Guitars and installed them right away.  After doing some research on the refretting process, I learned that just about every luthier has their own method. I assembled my own procedure by printing out this guide and annotating it with notes from this series of videos and this forum post. Along the way I found that the general consensus on refret jobs is that it’s past the “DIY” border and well into the realm of  “just get a professional to do it”. But whatever.

Hammering in new frets.

I ordered some fretwire, end nibbers and sanding supplies from StewMac, and used a piece of aluminum channel left over from Such and Such as my levelling tool. I tried to get really econo and skimp on a fretwire bending tool ($90), opting instead for this technique ($0). It took a few attempts to start producing nicely curved fretwire. Unfortunately, this resulted in a pretty wide range of fret quality.

As I worked, the fretboard acquired all sorts of scrapes, marks, burns and excess glue which really ought to help produce those vintage tones. The uneven curvature I was initially producing in the fretwire caused many of the upper frets to sit higher than those at the end of the neck. Sanding and levelling couldn’t quite alleviate this, so I’m now relying on a slight forward neck bow under string tension as a remedy. Real professional stuff.

With a fresh set of heavy strings, there is still some fret buzz. But not enough to drive me completely insane. While I might’ve been better off sending it to a professional guitar tech, it’s still quite a playable instrument – possibly even more so than before. And as intended, this job was a great learning experience.

It’s more comfortable than it looks.

Another guitar project from the past month – this time a one-nighter -  was adding a tremolo arm to the old Sears guitar that’s been floating around the space. It was already equipped with a tremolo bridge, it just required an arm to get those bends and squeals so key to our late-night, burned-out-on-my-project jam sessions.

An old piece of aluminum tubing cut to length, pressed flat at one end and drilled out to accommodate a 1/4″ bolt and fender washer did the trick nicely. I wish I’d come up with something a little more inventive, but this’ll do for now.

Come by the space on Thursday April 25 for our DIY Music Night as part of Philly Tech Week. You’ll be able to see and play with all of the music gadgets built at Hive, including guitars, synthesizers, amps, pedals, speakers, noise makers, plus a really cool karaoke machine.

Floppy Jukebox

De komende tijd zullen we een aantal (oude) projecten laten zien om indruk te krijgen van de projecten die we doen bij TkkrLab.

Als eerste onze onze Floppy Jukebox, een 4 tal oude Floppy drives die dmv een Arduino worden aangestuurd om muziek te maken.

Voor meer technische informatie zie onze wiki pagina.

 

 

Gismo: Labor 23 eV.

12 Jahre nach dem Chaosring Franken eV. gibt es in Würzburg und Umgebung wieder einen Chaos nahen, konsolidierten Vereinszustand. Entsprechend dem Jahrzehnt mit dem Hintergrund der globalen Hackersapcebewegung gegründet, ist der Labor 23 eV. in der Winterhaeuserstr. 23r, Wuerzburg zu finden.

Large Hackerspace Convention IV (#LHC4)

Hackerspaces of the world.
Get ready for another collision at the

Large Hackerspace Convention IV (#LHC4)

in the RaumZeitLabor Mannheim Germany on the

13th and 14th of April 2013

Join us for another meet-up about our world, the world of hackerspaces,
including our problems, our solutions, our projects, our structures, our
chaos, our members, our publicity and everything in and around the
hackerspaces movement.

This time, we return the LHC to its birth place in Mannheim.
We invite all hackerspaces to come to Mannheim and have a great time
with us, debating the status quo as well as the future of hackerspaces.
During the two days, we plan to have a barcamp-esque lecture program, to
be defined by the attendees.

If you already know that you would like to talk about a topic, please
send in your idea to info (ät) raumzeitlabor.de

The topics we want to put a focus on this year are:

*Laser cutters*
lots of hackerspace have acquired or built a laser cutter by now.
We want to share best practises, lessons learned, ideas,
differences between models, HOWTOs to prepare designs for cutting, etc.

*3D printing*
Even longer than the laser cutter trend, the plastic extrusion 3D
printers have invaded hackerspaces and help up make Bits tangible.
We want to share best practises, lessons learned, ideas, differences
between models, HOWTOs to prepare designs for printing, other methods
than hot extrusion, etc.

*Textile design*
RaumZeitLabor is not the only hackerspace that took a deep dive in
T-shirt and textile design and printing.
We want to explore techniques (foil, silk screen …), design ideas and
best practises. We will make our new cutting plotter available to you
for your own designs (can also cut vinyl foil for laptop stickers!)

*Organisation*
The ususal. A hackerspace needs to organise its chaos a bit in order to
really work. Or does it?
We want to share rule sets, lessons learned and general opinions about
this topic. What works, what doesn’t in your space?

*Can haz Moneyz pls?*
Financing the niceties that make a hackerspace comfy, starting with the
space itself, is the biggest task of a hackerspace to stay sustainable.
We want to share concepts for funding, sponsoring pro/contra, membership
fees, food and drink prices/revenues, etc.

The event – as most hackerspace events – is highly self-organized and
dependent on volunteers. Please consider showing up on Friday and giving
us a hand, setting everything up. And please consider giving a lecture
or workshop for any of the focus topic or any other topic you think the
community will find interesting.

All infos will be gathered at

http://lhc.raumzeitlabor.de

(and yes that’s a wiki page so feel free to contribute)
We’d love to see you in April in Mannheim!

[please forward this invitation to other hackerspaces]
