Adafruit And The Arduinos At Maker Faire

May 18, 2015 by Elliot Williams 67 Comments

The apparent lull on the Arduino front the last few weeks was just the calm before the storm that is the Bay Area Maker Faire (BAMF). Both companies claiming the Arduino name were there over the weekend, with news and new products in tow. Ironically, you could see from one booth straight over to the other. Small world.

Perhaps the biggest news from Arduino LLC is that hacker-friendly Adafruit is now going to be making officially-licensed boards in the US. Competing with this news, Arduino SRL brought its new boards, including the Yun Mini and ARM-powered Arduino M0. And [Massimo Banzi] and Arduino LLC seem to be taking an end-run around the Arduino SRL trademark by announcing the “Genuino” brand for European production. For all the details, read on!

Arduino IDE Becomes More Open, Less Snarky

May 13, 2015 by Elliot Williams 56 Comments

Version 1.6.4 of the Arduino IDE has been out for a little while now, and it has a couple of notable changes. To our eyes, the most interesting change makes adding support for non-standard boards and their configurations within the Arduino IDE a lot simpler. We’ll get into details below.

But before that, it’s time to bid farewell to the cheeky little popup window that would deliver a warning message when using a board bearing the USB IDs of their former-partner-turned-competitor. We absolutely agree with [Massimo] that the issues between Arduino SRL / Smart Projects and Arduino LLC are well-enough known in the community, and that it’s time for the popup to fade away.

Now on to the meat of this post. The new “Board Manager” functionality makes it significantly easier for other non-Arduino products to be programmed within the Arduino IDE. Adafruit has a tutorial on using the Board Manager functionality with their products, and it basically boils down to “enter the right URL, click on the boards you want, download, restart Arduino, bam!”

The list of unofficially supported third-party boards is still a bit short, but it includes some stellar entries. For instance, Adafruit has provided the files needed for the ESP8266, which recently received the Arduino treatment. This means that you can simply point your IDE at Adafruit’s URL, and it’ll set you up with everything needed to develop for the ESP8266 from within the comfy Arduino IDE.

Logic Noise: Taming The Wild Shift Register

May 4, 2015 by Elliot Williams 22 Comments

One of the best things about DIY synth building is that you can create devices that just don’t exist in the commercial marketplace. In this session, we’ll build a looper / sequencer the likes of which you may have never seen. And it’s groovy. Today we’ll also get back a little closer to the soul of the series. In this session, nothing is analog — this is pure Logic Noise.

The shift register is the centerpiece chip this session, and a great device in its own right. We’ve got a lot of ground to cover, so watch the teaser video and then let’s get going.

Vintage Computer Festival Europa 16.0: The Hackaday Report

May 2, 2015 by Elliot Williams 7 Comments

The 16th annual Vintage Computer Festival Europa (VCFe) is still ongoing this weekend in Munich, and of course Hackaday had to swing by. If you’re anywhere in Germany, you’ve still got until Sunday at 16:30 to check it out.

The theme for this year’s festival is “The East is ~~Red~~ Colorful” and that means vintage computers from the other side of the Iron Curtain. Here in (West) Germany, that naturally means a good representation of computers from the former Democratic Republic of Germany (DDR), but Czechoslovakia, Yugoslavia, and of course Russia were also in the house. There was far too much going on to cover it all, but here’s a few of the projects and computers that caught our eye.

Slick Six-Voice Synth For AVRs

April 27, 2015 by Elliot Williams 26 Comments

He started off making an AVR synthesized guitar, but [Erix] ended up with much more: a complete six-voice AVR wavetable synthesis song machine that’ll run on an ATMega328 — for instance, on an Arduino Uno.

If you’re an AVR coder, or interested in direct-digital synthesis or PWM audio output, you should have a look at his code (zip file). If you’d just like to use the chip to make some tunes, have a gander at the video below the break.

Lego Flip-dot Display

April 25, 2015 by Elliot Williams 10 Comments

We don’t need to mention that flip-dot displays are awesome. They use no power except in transitions, are visible on even the brightest of days, and have a bit of that old-school charm. So then it stands to reason that the flip-dot display that [AncientJames] made out of LEGO is awesome-plus. Heck, it even spells out “awesome”.

Logic Noise: Sequencing In Silicon

April 24, 2015 by Elliot Williams 12 Comments

In this session of Logic Noise, we’ll combine a bunch of the modules we’ve made so far into an autonomous machine noise box. OK, at least we’ll start to sequence some of these sounds.

A sequencer is at the heart of any drum box and the centerpiece of any “serious” modular synthesizer. Why? Because you just can’t tweak all those knobs and play notes and dance around at the same time. Or at least we can’t. So you gotta automate. Previously we did it with switches. This time we do it with logic pulses.
