Hack a Day
We’ve seen a lot of builds using electroluminescent wire, usually in the realm of costumes and props. Unfortunately, most electrical engineers don’t deal with blinking and dimming EL wire and panels and any tinkerer trying to control electroluminescence doesn’t have a lot of resources on how to control EL stuff. [ch00f] wanted to fill this knowledge gap, [...]

[Neoxy] always wanted surround sound for his computer, and one day he managed to get a hold of a dead 5.1 system. Why buy one when you can repair someone’s rubbish, right? That turned out to be easier said than done, but after several false-starts he managed to resurrect the audio system by replacing the microcontroller. We [...]

Chaos Communication Congress 27th (27C3) 2010 Abstract: At least if you have used all the features of a synthesizer, you probably ask the questions: "How can I modify it? How can I build a synthesizer myself? What features do I personally need?" This talk covers this topic from a theoretical and technical point of view. Since commercial synthesizers have been built, the interest in modifying existing synthesizers and building own synthesizers has increased. Nowadays there is a much bigger DIY (Do-It-Yourself) community, and the idea of building own synthesizers and modules has been even merged with the idea of open-source and creative-commons hardware. This gives a wide range of new possibilities. Another part of the talk will be a quick introduction of less or more known DIY-synthesizer projects and the demonstration of a DIY synthesizer based on MOS 6581-like synthesis (The Commodore SID), which can be built from quite cheap electronic components and give a wide range of possibilities for sound generation and a reasonable sound. This talk will briefly describe the basics of sound synthesis and what makes it so interesting. A little bit of basic knowledge is recommended, but not necessary.

A group of students at the University of Dundee have created this interesting prototype called Sound Sculpted. The goal was to sculpt clay using sound files drive the sculpting arms.

[Entropia] decided to try his hand at rolling is own sound card. He picked out a DAC chip, started his prototyping by studying the reference design from the datasheet, then went through several iterations to arrive at this working model. He chose to base the board around the PCM2706. It’s a digital to analog converter [...]

Believe it or not, the local Children’s Museum staff was happy that [Bill Porter] left this mess of wires and equipment in one of their offices.

Kanye West evidently got his own retro redesign by the original creator and the [...]

The echo box performs exactly as its name implies. If you tap out a rhythm on the lid, it will tap the same thing back to you. Except it isn’t tapping to make the sound, but vibrating. The concept is similar to the Knock Block. In that hack, a piezo element detected a rapping on [...]

Looks like [Dino] is getting the band back together. After a junkyard tube amp and a DIY tremolo stompbox, he’s back again, this time doing a bit of sound treatment in his studio. Most rooms naturally have a bit of flutter echo. You’ll notice this when you move into an apartment or new house – [...]

“I can’t hear myself in the mix,” “yeah, man, I’ll be there at 8,” and “dude, we need like four more mics.” Each and every one of these words is documented in actuarial tables and doesn’t bode well for your sound tech’s risk of a stroke. Luckily, there’s an even better way to kill your [...]

For his A-level electronic course work, [Andrew] decided to build a digital sound recorder that doesn’t use a microcontroller. [Andrew]‘s build captures audio from an on board microphone at 8000 samples/second. The audio is digitized into 8-bit sound data and sent to an SRAM. The recording and playback functions are controlled entirely by 4000-series logic chips. He [...]

As devices get smaller and smaller, it becomes a bigger challenge for engineers to squeeze a product’s components into an ever shrinking footprint.

He builds a simple dead [...]

High speed video is everywhere these days, but the cameras and necessary equipment is a bit out of reach for a hobbyist.

After reading about a Super Mario Brothers themed bathroom, [Jonathan] decided that it would be pretty cool to have his toilet play the “warp pipe” sound whenever anyone flushed.

Sound localization is very popular in law enforcement circles due to its accuracy and ability to quickly separate gunshots from other similar noises.

Open Sound Control (OSC) is a communications protocol that can be seen as a modern alternative to MIDI. It’s specifically designed to play nicely with network communication systems. The problem with using it along with Arduino-based gadgets is that you then need to use something like an Ethernet shield to provide the network connection. [Liam [...]
