The Solution To DJs Playing Their MacBooks

Posted on by

The greatest invention relating to music in the 20th century was multi-track recording, for which we have Les Paul to thank. The second greatest? Non-linear editing and Pro Tools. For some bizarre reason, we have Ricky Martin to thank for that because Livin’ La Vida Loca was the first #1 single to be recorded and mixed entirely in Pro Tools.

The third greatest invention in recording since Edison is the plugin. If you’ve already got a computer sitting in front of you, you’ve got every instrument ever made. All you need is a plugin. [Jan] was working on his …read more

An Open Source Toy Synth

Posted on by

If you thought the future of electronic musical instruments was massive Emerson-class modular synths, giant MPCs with pads the size of Dance Dance Revolution machines, or hilariously expensive polysynths, you couldn’t be more wrong. The future is, effectively, toys. Those tiny little Korgs you can stuff in your pocket are selling like hot cakes, and Pocket Operators are king of the hill. One of the more interesting musical toys is the Organelle, an aluminum enclosure with maple buttons laid out in a keyboard configuration. It’s a synth, it’s a sound engine, and it does produce some interesting noises. All the …read more

MIDI Controlled Neon

Posted on by

The people who make neon signs are a vibrant community with glass bending and high voltage electronics. There is a need, though, to sequence these neon signs, and it seems like MIDI is the way to do it. That’s what [david] is doing for his entry to the Hackaday Prize, and the results already look great.

The idea for this project is to transmit MIDI data to a controller that activates neon tubes accordingly. As for why [david] chose MIDI over DMX512 or some other protocol, the object here is to sync with music, and if you already have …read more

I Ate a Robot Hamburger Before the Restaurant Went Out of Business

Posted on by

The future is upon us and the robots will soon take over. Automated cars will put Uber drivers and cabbies alike out of work. Low-wage workers, like the people working behind the counter at McDonalds, will be replaced by burger-flipping robots. The entire operation of Spacely Space Sprockets, Inc. is run by a single man, pressing a single button, for four hours a day. This cartoon future is so fully automated that most people are unemployed, and all productive work is done by robots.

The first jobs to be replaced will be the first jobs teenagers get. These are low …read more

The 3D Printed Guitar

Posted on by

We just wrapped up the Musical Instrument Challenge in the Hackaday Prize, and that means we’re sorting through a ton of inventive electronic musical instruments. For whatever reason we can’t seem to find many non-electronic instruments. Yes, MPCs are cool, but so are strings and vibrating columns of air. That’s what makes this entry special: it’s a 3D printed physical guitar. But it’s also got a hexaphonic pickup, there are lights in the fretboard, and it talks to a computer for PureData processing.

First, the construction of this guitar. It’s mostly 3D printed, with the ‘frame’ of the body made …read more

Friday Hack Chat: FPGA Bootcamp

Posted on by

For this week’s Hack Chat, we’re going to be talking all about FPGAs, with our own resident FPGA expert.

This summer, Hackaday.io launched FPGA bootcamps, simple, easy-to-follow tutorials that will get you up and running with Verilog. These were all done by Al Williams, Hackaday’s resident FPGA hacker. Al’s an electrical engineer, author of over thirty books, countless magazine articles, and thousands of blog posts. He’s been an amateur radio operator for 41 years, and his first computer used an 1802 chip.

Now Al is putting a little bit of his wisdom over on Hackaday.io. He’s written up a bunch …read more

A Better Charger For Your Coin Cell Batteries

Posted on by

Rechargeable coin cell batteries are great for all your small projects. They look exactly like regular coin-cell batteries, but in a shocking turn of events you can recharge these little guys. They can put out a reasonable amount of current, and they’re small. Just what you need for your Arduino smart watch, or whatever else the kids are doing these days.

But if these batteries are rechargeable, you need a charger. That’s where [Jon]’s entry for the Hackaday Prize comes in handy. It’s a small, cheap charger for LIR2032 and other rechargeable batteries comes in. It’s barely larger than …read more

The Incredible Judges Of The Hackaday Prize

Posted on by

The last challenge of The Hackaday Prize has just ended. 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. In the next few weeks, we’ll be sending the judging sheets out to them, tallying the results, and in just under a month we’ll be announcing the winners of …read more

New Part Day: The RISC-V Chip With Built-In Neural Networks

Posted on by

After exploring a few random online shops one day, [David] (thanks for sending this in, by the way) ran across a very interesting chip. It’s a dual-core, RISC-V chip running at 400MHz. There’s 6 MB of SRAM on the CPU, and there’s 2MB for convolutional neural network acceleration. There is, apparently, WiFi on some versions. There are already SDKs available on GitHub, and a bare chip costs a dollar or two. Interested? Log in to Taobao, realize Taobao does pre-orders, and all this can be yours.

This is a preorder — because apparently you can do that as a seller …read more

Hackaday Links: October 7, 2018

Posted on by

Ah, crap. We lost a good one, people. [Samm Sheperd] passed away last month. We’ve seen his stuff before, from a plane with a squirrel cage fan, to completely owning a bunch of engineering students by auditing a class. The obit is available as a Google Doc, and there’s a Samm Sheperd Memorial Fund for the Big Lake Youth Camp in Gladstone, Oregon.

FranLab is closing down! Fran is one of the hardware greats, and she’s being evicted. If you’ve got 2000sqft of workshop space in Philly you’d like to spare, you know who to talk to. There will, probably, …read more
