Gecho Pocket Synth Looper

Posted on by

[Mario] wrote us with his synthesizer project that’s currently up on Kickstarter. It looks like a good amount of fun to play with, as you can see in the video on the Kickstarter page. But it’s also built to be easily hackable.

On the hardware front, it’s a tiny four-layer board that’s crammed with parts. At the core is an STM32F4 microcontroller and a DAC. Indeed, the build was inspired by other folks’ work on the STM32F4 Discovery dev kit that has been used to make some pretty interesting synthesizer devices. [Mario]’s version adds two stereo headphone outputs, two microphone …read more

Sporty Cars Making Fake Engine Noise

Posted on by

Following the monumental emissions-cheating scandal at VW, further horrible revelations demonstrate just how corrupt the modern automotive industry has become: many cars make fake engine noise. And we’re not just talking about those darn sneaky Priuses.

Ford, BMWs, Porsche, and yes, Volkswagen are all doing it, to different degrees. Some of the systems, like the one in the BMW M5, play engine sounds at low volumes through the stereo system. As you’d expect from a BMW, it’s an overly-technological solution: they have built essentially a BMW engine-sound synthesizer that responds to the tachometer and gas pedal data from the car’s …read more

The Most Flexible Synthesizer is DIY, Raspberry Pi

Posted on by

[Ivan Franco] sent us this great synthesizer project that he’s working on. Or maybe it’s more like a synthesizer meta-project: a synthesizer construction set. You see, what Pryth has is a Raspberry Pi inside that’s running a custom distribution that includes SuperCollider to generate the sound, OSC for the communication layer, and a Teensy with up to 80 (!) multiplexed analog inputs that you’ll connect up to whatever hardware you desire.

With the computer inside the box — the Raspberry Pi in question — you can easily make this system into a standalone musical instrument, without tethering it to your …read more

Not Just Another Alarm Clock

Posted on by

Even though [Stefan] sent in this link with the heading “Another Sunrise Alarm Clock“, it’s anything but plain. Sure, from the outside it looks like a simple and refined design, but the story of getting there is hardly straightforward.

Take that nice-looking luminous dial. [Stefan] made it himself, using the same techniques that he’s used for making his own watch faces. (Amazingly, he prints them out on a color ink-jet.) This is a sunrise wake-up clock, but if the bright LEDs don’t wake him up, there’s also a vintage DIY synthesizer project stuffed in the box in place of a …read more

The Music of a Sunset

Posted on by

What would you do if you suddenly went blind and could never again see the sun set? How would you again experience this often breathtaking phenomenon? One answer is music, orchestrated by the sun and the Weather Warlock.

Built by the musician [Quintron] (builder and inventor of insane electronic instruments), the Weather Warlock is an analog synthesizer controlled by — you guessed it — the weather. It translates temperature, moisture, wind and sunlight into tones and harmonics with an E major root chord. UV, light, moisture, and temperature sensors combined with an anemometer set up outside feed the weather data …read more

Modular Drum Machine Creates Random Rhythms

Posted on by

Don’t worry, the rhythms themselves aren’t random! That would hardly make for a useful drum machine. [kbob]’s creation does have the ability to randomly generate functional rhythms, though, and it’s all done on a breadboard.

The core of this tiny drum machine is two Teensy dev boards. One is an FM synth tuned to sound like drums, and the other is a random rhythm generator with several controls. The algorithms are from Mutable Instruments’ open source Eurorack modules. The entire thing fits on a breadboard with JIGMOD modules for the user interface. The machine runs on lithium batteries in the …read more

Autonomous Musical Soundscapes from 42 Fans and 7 Lasers

Posted on by

[dmitry] writes in to let us know about a new project that combines lasers with fans and turns the resulting modulation of the light beams into an autonomous soundscape. The piece is called “divider” and is a large, wall-mounted set of rails upon which seven red lasers are mounted on one end with seven matching light sensors mounted on the other end. Interrupting the lasers’ paths are forty-two brushless fans. Four Arduino Megas control the unit.

Laser beams shining into light sensors don’t do much of anything on their own, but when spinning fan blades interrupt each laser beam it modulates the solid beams and turns the readings …read more

Hackaday Prize Entry: A Cute Synthesizer

Posted on by

For electronics aficionados, there are few devices cooler than music synthesizers. The first synths were baroque confabulations of opamps and ladder filters. In the 70s and 80s, synths began their inexorable march toward digitization. There were wavetable synths that stored samples on 27-series EPROMs. Synths on a chip, like the MOS 6581 “SID chip”, are still venerated today. For his Hackaday Prize entry, [Tim] is building his own synthesizer from scratch. It isn’t a copy of an old synth, instead it’s a completely modern synthesizer with a classic sound.

[Tim] is a former game developer and has already released a …read more

Curiously Delightful Things Done with Lasers and Projectors

Posted on by

Seb Lee-Delisle has built a career around large installations that use powerful lasers and high-end projects to make people happy. It’s a dream job that came to fruition through his multi-discipline skill set, his charismatic energy, and a mindset that drives him to see how he can push the boundaries of what is possible through live interaction.

His talk at the Hackaday | Belgrade conference is about his Laser Light Synth project, but we’re glad he also takes a detour into some of the other installations he’s built. The synth itself involves some very interesting iterative design to end up …read more
