Calculator Music with Houston Tracker

Not too long ago I read about how some genius called ‘irrlicht project’ had hacked old Texas Instruments graphing calculators so they could be used to make 1-bit music. Naturally, I had to have a bash at this myself. There’s something particularly special and rewarding about being able to compose whole tracks on devices that were never intended to work that way.

The models that support the ‘Houston Tracker‘ software are seemingly everywhere in the US, as they were apparently a mandatory purchase for many schools. That means they can usually be picked up fairly cheap second hand over there. However, as it turns out, these weren’t all that prevalent in the UK, so they are still fairly pricey – coming in at around £30 on eBay.

I finally got an okay deal though, and got to work getting Houston Tracker onto the device. It’s not all that straightforward, as you need a specific kind of cable – which costs almost the same as the damn calculator. Importing one from America worked out to be the most cost effective route in the end. Installation wise, there’s a lot of fiddling about to get the dependencies right on OSX, unless you use MacPorts – which saved the day. Once it was all up and running though, it was pretty good fun to use – with a whole host of features that I didn’t expect.
