Boing Boing pal and maker superhero Mitch Altman, creator of the amazing TV-B-Gone, spent several years designing a simple-yet-powerful DIY music synthesizer that he could use to teach creative electronics and also digital signal processing to kids and adults. The result is the ArduTouch Music Synthesizer! And it's only $30! Demo videos below. Mitch wrote about the method behind his maker madness in IEEE Spectrum. From his essay:
As a kid with a lust for music, I was rocked by the Moog synthesizer sounds of 1968’s Switched-On Bach. I needed to learn how to make those sounds! Thus began a lifetime of learning and synthesizer making while I made my way in the tech industry, where I ultimately created the TV-B-Gone, a gadget that lets you turn off almost any model of remote-controlled television. Since the popular success of the TV-B-Gone, I’ve created many fun, open-source, hackable hardware kits for the maker workshops I give around the world. In these workshops, newbies learn to solder, tinkering their way into electronics and microcontrollers. Remembering my own youth, I wanted to provide them with a kit that was simple to assemble [PDF] and use but still a fully fledged music synthesizer.
The result was the US $30 ArduTouch. This project incorporates, on a single board, a touch keyboard, an ATMega328P (the same processor used in the Arduino Uno), and an audio amp with a speaker. It also has a software library that can serve as an entry point into the world of digital signal processing.

One genre of 19th Cen illustrated pamphlet was the "Cries of London" (previously), which celebrated the market traders' characteristic sales patter, which were catalogued as a kind of urban birdsong.
Last year while I was on tour in Australia with my novel Walkaway, I sat down for an interview with legal scholar Rebecca Giblin (previously), whose Authors' Interest project studies how we would craft copyright (and other policies) if we wanted to benefit creators, rather than enriching corporations; we talked about the power and limits […]
Use a single password for every website, and you’re compromising your security. Use a different one each time, and you’re bound to lose track of them. The solution? RoboForm Everywhere, a catch-all tool that will not only manage the passwords on every site you visit but generate better ones. As a simple password database, it’s […]
Just a reminder: Print isn’t dead. And now that printers are becoming as portable as cell phones, it might be around for quite some time. Enter the MEMOBIRD Mobile Thermal Printer, a mini-printer that is versatile, portable – and most importantly, never needs a refill on ink or toner. Measuring just a few inches around, […]
What do Facebook, Twitter, YouTube and Google all have in common? Somewhere in their framework, they all use MySQL, that most versatile (and free!) of database management systems. And they’re not alone. If your company or the one you’d like to work for wrangles data (and who doesn’t?), they’re going to need someone with a […]
