Electromagnetic Wave 2013

I found some pictures on my camera, so here’s a bit of a belated look at the Northackton trip to Electromagnetic Wave.

The ship

The Motorschiff Stubnitz…

...which Adrian couldn't resist hacking

Set-up of stage alpha seemed to be a little running behind as the speakers started

A good time was had by all, although set-up of stage alpha seemed to be a little running behind…

Laser cutter

Last month we had a proper hack evening and finally installed the laser cutter!

We had a bit of a bash with it on the 19th, but we’re going to have a proper session next meeting, tomorrow. Bring ideas!

First cut

As we couldn’t resist having a proper go, we tried a keyfob from Nottinghack’s laser cutter manual. Came out lovely.

There’s lots more detail on training, safety, usage and materials on the Laser Cutter static page. And I’ve posted some more laser cutter experiments from when the cutter was in my garage on http://lasiverse.wordpress.com/.

Happy Birthday, and variations thereupon

Northackton is 3 years old this month.  The exact week can be derived from reading the first few posts in the archives, and/or by looking at flickr, but I won’t spoil it for you.  To celebrate, Andy had suggested an informal competition to produce devices that play the Happy Birthday tune.

A number of entries were made, and here they are for your enjoyment:
Andy’s recreation of our first attempt to play music bottles with servos.  He authentically captured our discovery that servos aren’t very good at this
 
Andy’s second entry was an Arduino piezoplayer:
  
Adrian made a xylophone using old pinball chime solenoids.  It only had three notes, but it played them really well!
 
Mine was another Arduino player, but with a mini speaker in a little box.  I don’t have any video of it yet, it’ll have to go up in a second post.
However the show was stolen by newcomers Mike and James who came for help making their ring modulator work.  Happily they’d got it almost entirely right, and some slight tweaking and a lot of soldering produced a very special song.
