Friday Hack Chat: Air Hacking

Posted on by

The field of soft robotics sure seems a lot less mature than your standard servo motor and metal framed robot arms. Maybe that’s because building a robot to flex is harder, and maybe it’s because the best methods of constructing soft robotics have only been around for a decade or so. Maybe, though, it’s because it’s hard to control air.

For this week’s Hack Chat, we’re going to be discussing Air Hacking with [Amitabh Shrivastava]. [Amitabh] is a grad student at ITP, NYU studying creative technology, where he makes interactive art, tools for research, and experiments with various materials. Lately …read more

Racing the Beam and Dropping Some Beats

Posted on by

The heart of the Atari 2600 wasn’t the 6502 (or the 6507 for the pedants), it was the TIA chip. This is the chip responsible for drawing graphics on the display, racing the beam, and extremely limited support for sound generation. We haven’t seen many attempts of using the Atari 2600 for chiptunes, but that doesn’t mean it can’t be done. [John Sutley]’s Syndrum, a take on an Atari 2600 drum machine is nearly a work of art. It’s a custom cartridge for the wood-paneled Atari, and an impressive input device that turns this classic console into a beat machine …read more

The Spirit Of The 80s Lives On In A MIDI Harmonica

Posted on by

In the 1980s, there was a synthesizer that you could play like a harmonica. This device was called the Millioniser 2000. It utilized HIP (Harmonica In Principle) technology. The Millioniser 2000 was a breath controller wrapped in chrome-colored plastic embossed with its logo in an odd, pre-vaporwave aesthetic, and connected to a gray and green sheet metal enclosure loaded up with DIN jacks. The Millioniser 2000 is absolutely the pinnacle of late 70s, early 80s design philosophy. If it were painted brown, the Universe would implode.

Because of the rarity and downright weirdness of a harmonica synthesizer from the 80s, …read more

Putting a Motor Inside a Speed Controller

Posted on by

One of the more interesting hacks we’ve seen this year is [Carl]’s experimentations with making motors out of PCBs. Honestly, it’s surprising no one has done this before — a brushless motor is just some coils of wire and a few magnets; anyone can turn some coils into traces and make a 3D print that will hold a few magnets. This latest advancement is something else entirely. It’s a motor and an electronic speed controller all in one.

This project is a continuation of [Carl]’s PCB motor project, which started with him routing coils for a brushless motor as traces …read more

The Incredible Judges Of The Hackaday Prize

Posted on by

The time to enter The Hackaday Prize has ended, but that doesn’t mean we’re done with the world’s greatest hardware competition just yet. Over the past few months, we’ve gotten a sneak peek at over a thousand amazing projects, from Open Hardware to Human Computer Interfaces. This is a contest, though, and to decide the winner, we’re tapping some of the greats in the hardware world to judge these astonishing projects.

Below are just a preview of the judges in this year’s Hackaday Prize. We’re sending the judging sheets out to them, tallying the results, and in less than two …read more

Hackaday Links: October 21, 2018

Posted on by

A few weeks ago, we got word [Fran] was being kicked out of her workshop. You might remember [Fran] from her exploits in reverse engineering the launch computer for the Saturn V, her work on replicating the DSKY from an AGC, her visit to the Air & Space Museum annex (so jealous), and her other musical adventures. Why is she getting kicked out? Philly’s getting gentrified, ya jabroinis. Now, there’s a GoFundMe for a new Fran Lab. Go on and ring that bell.

Everyone needs a Sharpie sitting around, so how about one that weighs a pound or so? [MakingStuff] …read more

Turning The Deep Note Into A Game

Posted on by

One of the most famous pieces of computer-generated music is the Deep Note, the audio trademark for THX. It begins with a dozen or so voices, randomly tuned between 200 and 400 Hz, then glissandos to a frequency spread of three octaves. Put that through a few thousand watts of a speaker system, play it before Jedi, and the audience will be listening.

The original THX Deep Note was created on hundreds of thousands of dollars worth of hardware running 20,000 lines of code, but that was in 1983. Now we have cheap microcontrollers, so of course, you can …read more

Finally, An Open Source MIDI Foot Controller

Posted on by

MIDI has been around for longer than most of the readers of Hackaday, and you can get off my lawn. In spite of this, MIDI is still commonly used in nearly every single aspect of musical performance, and there are a host of tools and applications to give MIDI control to a live performance. That said, if you want a MIDI foot controller, your best bet is probably something used from the late 90s, although Behringer makes an acceptable foot controller that doesn’t have a whole bunch of features. There is obviously a need for a feature packed, Open Source …read more

Can You Build An Open Source Pocket Operator?

Posted on by

Toys are now musical instruments. Or we’ll just say musical instruments are now toys. You can probably ascribe this recent phenomenon to Frooty Loops or whatever software the kids are using these days, but the truth is that it’s never been easier to lay down a beat. Just press the buttons on a pocket-sized computer.

One of the best examples of the playification of musical instruments is Pocket Operators from Teenage Engineering. They’re remarkable pieces of hardware, and really just a custom segment LCD and a few buttons. They also sound great and you can play real music with them. …read more

Hacking Nature’s Musicians

Posted on by

We just wrapped up the Musical Instrument Challenge in the Hackaday Prize, and for most projects that meant replicating sounds made by humans, or otherwise making musicians for humans. There’s more to music than just what can be made in a DAW, though; the world is surrounded by a soundscape, and you only need to take a walk in the country to hear it.

For her Hackaday Prize entry, [Kelly] is hacking nature’s musicians. She’s replicating the sounds of the rural countryside in transistors and PCBs. It’s an astonishing work of analog electronics, and it sounds awesome, too.

The most …read more
