Successfully Reading a Midi File

In my previous post I covered the Arduino-based circuit I built to strike the chimes. I’ve also, with a little effort, gotten the Sparkfun MicroSD shield to work with the Arduino Mega 2560, so I’m now in the thick of writing the software to read music files for the Robotic Glockenspiel.

Not happy with the Arduino Midi libraries I’ve seen (they don’t seem very file-oriented), I’ve written the bones of what will become a Midi file-reading library. This library will enable an Arduino Sketch to read events from a Midi file, one by one, so that it can play the notes with the proper timing.

A Little Info on Using SSL in Your Web Site

I recently made a rash Tweet saying that if you don’t have SSL (Secure SocketsLayer; what HTTPS uses) your WordPress site will be hacked. That’s an overstatement. I’ve known people who’ve run WP sites without SSL with no problems.

So here’s a little web SSL orientation for people who have better things to do than learn the details of computer security.

Cutting and Tuning Robotic Glockenspiel Chimes

After a few weeks of experimentation, I think I can now write sensible notes on how to cut and tune the chimes for a glockenspiel (metal xylophone) out of metal conduit. This is the first step of my Robotic Glockenspiel project, which I hope to end with a network-connected, Arduino-controlled set of chimes that can play Christmas carols.
