FrankenKorg; or, The Modern Remote Keyboard

Posted on by

On a dreary night in November, [Smecher] collected the instruments of electronic life around him to infuse a musical spark into FrankenKorg — a resurrected keytar.

This hack is a “re-braining” of a RK-100 Korg Keytar, replacing the original circuits with an ATMega32 — the original functionality and appearance are preserved allowing any restored version of the original boards to be seamlessly re-integrated. In light of that, the original boards were ditched after a brief investigation, and a haphazard building process on a protoboard began. Three LS138 3-8 demuxers that accompany the ATMega handle scanning the keys since there weren’t …read more

MIDISWAY Promises to Step Up Your Live Show

Posted on by

If you like to read with gentle music playing, do yourself a favor and start the video while you’re reading about [Hugo Swift]’s MIDISWAY. The song is Promises, also by [SWIFT], which has piano phrases modulated during the actual playing, not in post-production.

The MIDISWAY is a stage-worthy looking box to sit atop your keys and pulse a happy little LED. The pulsing corresponds to the amount of pitch bending being sent to your instrument over a MIDI DIN connector. This modulation is generated by an Arduino and meant to recreate the effect of analog recording devices like an …read more

Push Buttons, Create Music With A MIDI Fighter

Posted on by

Musicians have an array of electronic tools at their disposal to help make music these days. Some of these are instruments in and of themselves, and [Wai Lun] — inspired by the likes of Choke and Shawn Wasabi — built himself a midi fighter

Midi fighters are programmable instruments where each button can be either a note, sound byte, effect, or anything else which can be triggered by a button. [Lun]’s is controlled by an ATmega32u4 running Arduino libraries — flashed to be recognized as a Leonardo — and is compatible with a number of music production programs. He opted …read more

Tough Pi-ano can Take a Punch

Posted on by

There will be no delicate solos for [24 Hour Engineer’s] Tough Pi-ano. It was built to soak punishment from aggressive youngsters in musical therapy, specifically those on the autism spectrum and those with Down’s syndrome. The Tough Pi-ano will be bolted to a wall with heavy-duty shelf brackets so it can’t fall on anyone. The keyboard is covered in plastic and it doesn’t have any exposed metal so there will be no splinters.

[24 Hour Engineer] made a short video demonstration and if you listen closely, he has a pun in all but one sentence. We love that kind of …read more

Acoustic Accordion Becomes MIDI; Oh the Complexity!

Posted on by

Everyone knows accordions are cool — they look fly, make neat noises, and get your romantic interests all hot and bothered. What isn’t cool is being relegated to acoustics only. How are you going to play a packed stadium or lay down a crystal clear track like that? You could go out and buy an electric accordion, but even low-end models carry a hefty price tag. But, this is Hackaday, and you know we’re going to be telling you about someone who found a better way.

That better way, shown in a build by [Brendan Vavra], was to take an …read more

Smartphone Bench Instrument Apps: Disappointment or Delight?

Posted on by

If you are interested in electronics or engineering, you’ll have noticed a host of useful-sounding apps to help you in your design and build work. There are calculators, design aids, and somewhat intriguingly, apps that claim to offer an entire instrument on your phone. A few of them are produced to support external third-party USB instrument peripherals, but most of them claim to offer the functionality using just the hardware within the phone. Why buy an expensive oscilloscope, spectrum analyzer, or signal generator, when you can simply download one for free?

Characterizing A Cheap 500MHz Counter Module

Posted on by

An exciting development over the last few years has been the arrival of extremely cheap instrumentation modules easily bought online and usually shipped from China. Some of them have extremely impressive paper specifications for their price, and it was one of these that caught the eye of [Carol Milazzo, KP4MD]. A frequency counter for under $14 on your favourite online retailer, and with a claimed range of 500 MHz. That could be a useful instrument in its own right, and with a range that significantly exceeds the capabilities of much more expensive bench test equipment from not so long ago. …read more

Musical Proximity Detection Pet Bowls

Posted on by

An essential skill for a maker is the ability to improvise or re-purpose existing materials into new parts. Sometimes, one needn’t make many modifications to create something new, as is the case with [Robin Sterling] and his musical pet bowl.

Originally, it was a sealed pet bowl that opened when the proximity sensors detected an approaching pet. Having helped design the bowl, [Sterling] had a bit of an advantage when he decided to convert it into a theremin/light harp-esque instrument for the company BBQ. He routed the PWM outputs from each of the three proximity sensors (in each of the …read more
