Music From Outer Space

If you want to dip your toes into the deep, deep water of synth DIY but don’t know where to start, [Atarity] has just the resource for you. He’s compiled a list of 70 wonderful DIY synth and noise-making projects and put them all in one place. And as connoisseurs of the bleepy-bloopy ourselves, we can vouch for his choices here.

The collection runs the gamut from [Ray Wilson]’s “Music From Outer Space” analog oddities, through faithful recreations like Adafruit’s XOXBOX, and on to more modern synths powered by simple microcontrollers or even entire embedded Linux devices. Alongside the links to the original projects, there is also an estimate of the difficulty level, and a handy demo video for every example we tried out.

Our only self-serving complaint is that it’s a little bit light on the Logic Noise / CMOS-abuse side of synth hacking, but there are tons of other non-traditional noisemakers, sound manglers, and a good dose of musically useful devices here. Pick one, and get to work!

The current Mac Pro is a masterpiece of design that looks like a trash can. We’ve been waiting for someone to take one of these computers and stuff a MiniITX board in there, but seeing as how the Mac Pro costs $3000, that probably won’t happen anytime soon. Here’s the solution. It’s a trash can computer case that is also too expensive for what it is. Now all we need is someone to put a big fan inside one and turn this computer into a wacky waving inflatable arm flailing tube man.

[Mike Harrison] recently got his hands on a $20,000 SPARC CPU module. This is an enormously thick board that must be dozens of layers thick. How many layers was an open question until he put the board in a CNC milling machine. The setup is pretty much what you would expect with a few lines of g-code repeated over and over. The real trick comes from using one of the outputs for lubricant to trigger the shutter release on a camera. How many layers were in the CPU module? About 30, or something like that.

Almost a year ago, we saw the latest advances in perfboard. It was a perfboard with each hole connected to rows and columns on a selectively solderable orthogonal busses. Something like that. Actually, we still can’t wrap our head around it. Now, it’s a crowdfunding campaign with a few new and useful features. There’s also a layout tool that will show you where to place your components and where to make solder bridges.

[Ray Wilson] started Music From Outer Space, the place to learn about DIY analog synthesizers. Ray now has cancer, and as you can imagine, being a self-employed engineer specializing in analog synthesizers doesn’t provide great health coverage. [Ray]’s family set up a GoFundMe page to pay for the medical expenses.

We haven’t seen much in the land of 3D scanners, and we’re betting most of that is because they’re so expensive. The guys from CowTech have a kickstarter up for a 3D scanner that’s just $99. It’s based on the Ciclop scanner but designed around a custom Arduino shield and remains fully open source.

Remember the screen printed electroluminescent displays that were printed directly onto t-shirts from a few months ago? Now that company is working on a much cooler design: the Hackaday Jolly Wrencher. It works, but there are still a few problems: they’re setting the shirt on fire a little. Don’t worry, if these are ever reasonably safe and somewhat affordable, an EL Jolly Wrencher shirt will be in the Hackaday Store.

Need a rechargeable multimeter? It’s actually pretty easy. With an 18650 Lithium Ion cell and a 9V boost converter, this circuit will fit in most devices that need a 9V battery. To do this right, you’ll also need a USB charging port, to be used once every couple of years when the battery needs charging.
