Vintage Electronics Magazines Predicted Our Current Future

July 13, 2015 by 57 Comments

Do you remember the magazine Popular Electronics? What about Radio Electronics? These magazines were often the first exposure we had to the world of hacking. In December we learned that Americanradiohistory.com has gone to the trouble of scanning nearly every copy of both, and continues to add many many others — posting them online for us to enjoy once more. Since then we’ve been pouring through the archive pulling out some of the best in terms of nostalgia, entertainment, and fascinating engineering.

Yes much of this material is very dated; CB Radios, all-mighty computers, phasors, stun guns, levitating machines, overly complex circuits for simple tasks, and aviator eyeglasses. But found among all of this, many innovative mixed-signal circuits and other interesting ideas that have been developed into our tech-centric world. Many of those modern inventions you’ve welcomed into your life actually started long-long ago in the forward-thinking hacks shown off in these publications. The Google Glass precursor seen above is but one example. Keep reading to see the early roots of the tech we tend to think of as “new”.

Hackaday’s Interview With Arduino CEO [Massimo Banzi]

July 7, 2015 by 25 Comments

I caught up with [Massimo Banzi] at the Shenzhen Maker Faire to talk about manufacturing in China, the current and future of Arduino, and how recent events may shape the Open Hardware landscape.

The big news from Arduino at SZMF is a new partnership with Seeed Studio to manufacture theGenuino. This is an official Arduino board manufactured in China for the Chinese market. Knowing that the board is official and connected to the founders is key point to get makers to adopt this hardware. [Massimo] makes a good point about the ideal of “Proudly Made in China” which I could see as a selling point for the burgeoning maker market there. This may be a growing principle in China, but in an ocean of clone boards it sounds like a tough path forward. On the other hand, their booth was mobbed with people putting in new orders.

[Massimo] belives the current Arduino strife has actually served to move the project forward. He cites the schism between arduino.cc and arduino.org for catalyzing manufacturing partnerships with both Adafruit Industries and Seeed Studios. This has resulted in official Arduino hardware that is not made only in Italy, but made in the region the hardware will be used; NYC for US orders, Shenzhen for China orders.

Our discussion wraps up with a plea from [Massimo] for the Hackaday community to be a little less fickle about projects using Arduino. That one makes me chuckle a bit!

Stenography (Yes, With Arduinos)

July 6, 2015 by 40 Comments

What’s the fastest keyboard? Few subjects are as divisive in the geek community. Clicky or squishy? QWERTY or Dvorak? Old-school IBM or Microsoft Natural? The answer: none of the above.

danger-court-reporter-tyingThe fastest normal-keyboard typists (Dvorak or Qwerty) can get around 220 words per minute (wpm) in bursts. That sounds fast, and it’s a lot faster than we type, but that’s still below the minimum speed allowable for certified court reporters or closed captioners. The fastest court reporters clock in around 350 to 375 wpm for testimony. But they do this by cheating — using a stenotype machine. We’ll talk more about stenography in a minute, but first a hack.

The Hack

[Kevin Nygaard] bought a used Stentura 200 stenotype machine off Ebay and it wasn’t working right, so naturally he opened it up to see if he could fix it. A normal stenotype operates stand-alone and prints out on paper tape, but many can also be connected to an external computer. [Kevin]’s machine had a serial output board installed, but it wasn’t outputting serial, so naturally he opened it up to see if he could fix it. In the end, he bypassed the serial output by soldering on an Arduino and writing a few lines of code.

shot0001The serial interface board in [Kevin]’s machine was basically a set of switches that made contact with the keys as they get pressed, and a few shift registers to read the state of these switches out over a serial connection. [Kevin] tapped into this line, read the switch state out into his Arduino, and then transmitted the correct characters to his computer via the Arduino’s serial over USB. (Video demo) As hardware types like to say, the rest is a simple matter of software.

A Perfect San Francisco For Hackaday Prize Worldwide

July 6, 2015 by 3 Comments

Whew, that was a perfect day. Seriously. A few weeks back, on Saturday June 13th PCH International opened their doors for the Hackaday Zero to Product workshop. I don’t live in California, so having two huge glass garage doors making up one entire wall of your office is odd to me. But on a perfect day like this one it was something miraculous.

The Workshop Begins

We opened the Workshop at 9:30am and those lucky enough to get a free ticket before the event was full streamed in. The topic at hand was a transfer of knowledge on professional level PCB design and once again [Matt Berggren] didn’t disappoint. A former Altium veteran, experienced hardware start-up-er-er, and all around circuit design guru, [Matt] has a natural and satisfying way of working with the many questions that arise while also following his epic talk framework. There must be around a hundred slides in his presentation that covers the bases from component selection, to signal routing, to material selection (substrate, copper density, solder mask material) and a lot more.

The day ran in segments…. sign-in followed by coffee and bakery goods and a talk on Open Hardware from [Ryan Vinyard]. He is the Engineering Lead at Highway1, the well-known hardware startup accelerator which provided a space for the event in the PCH Innovation Hub building. From there we dropped into the first segment of Zero to Product and started riffing on all things PCB design.

A break for salad and pizza three hours later lead into the final two sessions that are broken up by a social pause. Thanks to our Hackaday Prize Sponsors (Atmel, Freescale, Microchip, Mouser, and Texas Instruments) we had plenty of time to discuss the builds each person is planning and to connect them with sponsor-supplied dev boards to help with the prototyping.

We have an album up so that you can check out all the pictures from this event. We’ve held the Zero to Product workshop in Los Angeles, and Shenzhen as well in the recent weeks. Keep watching Hackaday to learn of future opportunities to take part in events in your area!

Maker Faire Kansas City: That’s A Wrap

July 5, 2015 by 1 Comment

The 5th annual Kansas City Maker Faire was as fun as ever, but it definitely felt different from previous years. There seemed to be an unofficial emphasis on crafts this year, and I mean this in the broadest sense of the word. There was more exposure for the event in the local media, and this attracted a wider variety of faire-goers. But the exposure also brought more corporate sponsorship. This wasn’t an exclusively bad thing, though. For instance, several people from Kansas City-based construction firm JE Dunn were guiding mini makers through a birdhouse build.

Many of the this year’s booths were focused on a particular handicraft.  A local music shop that makes custom brass and woodwind instruments had material from various stages of the building process on display. Several tables away, a man sat making chainmaille bags. At one booth, a girl was teaching people how to fold origami cranes. Several makers had various geek culture accessories for sale, like a shoulder bag made from a vintage Voltron sweatshirt. The guys from SeeMeCNC made the 12-hour drive with the Part Daddy, their 17-foot tall delta printer. They printed up a cool one-piece chair on Saturday, then made a child-sized version of it on Sunday.

The entire lower level of the venue was devoted to a series of exhibits related to the film and television industry. Collectively, they covered the entire production process from the casting call to the red carpet. Several local prop and costume makers were showing off their fantastic creations, including [Steven] of SKS Props. He started making video game props for fun a few years ago. These days, his work adorns the offices of some of those same game companies.

Of course, there was plenty to see and do outside, too. All the kids playing human foosball were having a blast. LARPers larped next to lowriders and food trucks, power wheels raced, and a good time was had by all.
