Peaceful tuning, Pacifica 112

Hello again!
It's been over a year since my last post (Pure Drumming). I started Electric Penguinland as a series of notes-to-self, to write up things that were difficult to discover online. I'm glad people have found the odd thing I've posted useful, so I'm picking up with the article that I was planning to start last year with: replacing the tuners on a Yamaha Pacifica.

Pure drumming

All too often I find ways to distract myself when I've intended to do some guitar practice. Recently I thought it would be nice to create some drum tracks to play with. "No problem!" You say, "Use Hydrogen." This is a start, but what if you don't know much about drumming and find clicking beats on a track comes out a bit flat? The first thing to come to mind was to try some MIDI pads, but that seemed like overkill, especially when something with buttons on it was much closer to hand—my Xbox 360 controller.

MathJax posts

My posts on the string bend calculator used MathJax to display the equations used. But I ended up struggling a while to get them to work on mobile devices. The problem is this: typically MathJax loading needs to go into the document head, but that means editing your blog template.

If you play guitar then you need to tune it from time to time, unless you're deeply in to experimental music.

Bending with Dojo part 3: Slight return

This is the last of three posts about building the string bend calculator and maybe the most interesting to anyone other than me. Part 1 dealt with the basic physics and Part 2 with building the Javascript app. All that's left is to wonder what it all means.

Bending with Dojo part 2: Stretching in the Dojo

Following on from Part 1, I wanted to make an interactive way to explore the mechanics of string bending. A spreadsheet is the simplest way to do that, but it needs users to download a file and open it up with the right program. A web-app only needs a browser and internet access to use, but takes a bit more assembly. To cut down the amount of DIY needed it's common to use a framework. JQuery is probably the most commonly used, but without built-in support for plots, so I went for the slight more complex Dojo.
I tried to make the maths background in Part 1 understandable for a general audience, but this Dojo section is going to have to assume you know a few programming terms. If that doesn't sound like your thing, then maybe you're just looking for the string bend calculator.
