Intel’s Vision For Single Board Computers Is To Have Better Vision

May 26, 2017 by Mike Szczys 33 Comments

At the Bay Area Maker Faire last weekend, Intel was showing off a couple of sexy newcomers in the Single Board Computer (SBC) market. It’s easy to get trapped into thinking that SBCs are all about simple boards with a double-digit price tag like the Raspberry Pi. How can you compete with a $35 computer that has a huge market share and a gigantic community? You compete by appealing to a crowd not satisfied with these entry-level SBCs, and for that Intel appears to be targeting a much higher-end audience that needs computer vision along with the speed and horsepower to do something meaningful with it.

I caught up with Intel’s “Maker Czar”, Jay Melican, at Maker Faire Bay Area last weekend. A year ago, it was a Nintendo Power Glove controlled quadcopter that caught my eye. This year I only had eyes for the two new computing modules on offer, the Joule and the Euclid. They both focus on connecting powerful processors to high-resolution cameras and using a full-blown Linux operating system for the image processing. But it feels like the Joule is meant more for your average hardware hacker, and the Euclid for software engineers who are pointing their skills at robots but don’t want to get bogged down in first-principles of hardware. Before you rage about this in the comments, let me explain.

Hackaday’s BAMF Meetup Spills Into The Streets Of San Mateo

May 24, 2017 by Mike Szczys 11 Comments

Saturday night marked the fourth annual Hackaday BAMF meetup. The night when weary exhibitors close up their booths at Bay Area Maker Faire and head over to O’Neil’s Irish Pub where the real fun starts. There are many drawbacks to having a booth; you’re on your feet all day repeating the same small snippet to everyone passing by, and usually you don’t get much of a chance to mingle with friends old and new.

Walking into the meetup, it was striking to watch aching bodies slow with weariness perk up to the energy and excitement of the Hackaday Community incarnate. Join me after the break for a peek into the fun of the evening.

Need For New Hobby Leads To Stone Marbles

May 18, 2017 by Mike Szczys 14 Comments

[Tom Lange] said he was looking for a new hobby when he saw a marble made out of stone and wondered what goes into making one for himself. Fast forward three years and he set up shop at the Madison Mini Maker Faire to show off the tools he built and the fascinating glossy orbs he’s produced. Read on to see the awesome process he uses to turn a hunk of stone into a perfect marble.

A Very Large VU Meter Indeed

May 16, 2017 by Jenny List 18 Comments

It used to be a must-have on any hi-fi, a pair of moving coil meters or LED bar graphs, the VU meter. Your 1980s boombox would have had them, for example. VU, for “Volume Units”, is a measure of audio level, and the fashion for its visual measure in consumer audio equipment seems now to have largely passed.

The LED bar graph VU meters were invariably driven by the LM3915, a chip that contains a resistor ladder and a stack of comparators which can drive LEDs directly. [Juvar] has taken an LM3915, and used it to drive a set of opto-isolated triacs which in turn drive a stack of appropriately coloured mains LED bulbs concealed within an Ikea Vidja lamp. The result is a huge and very bright VU meter that is as much a lighting effect as it is a measure of sound level.

He’s posted a video of the lights in action, and we’ve placed it below the break. There is a cameo appearance from his cat, and one can’t escape the feeling that it is wasted on a small room and would be at its best before a dance floor. Still, it’s a neat lighting effect and a new use for a classic integrated circuit.

It’s Back! Hackaday Meetup At Bay Area Maker Faire

May 15, 2017 by Mike Szczys No comments

If you’re in the Bay Area this weekend, the only place to be on Saturday night is O’Neill’s Irish Pub in San Mateo. Hackaday is once again hosting a meetup after Maker Faire closes for the evening, and you don’t want to miss it. Please RSVP now.

This is the fourth year of our BAMF meetup and we’re continually amazed at the turnout — we pack ’em in and it’s not just because the first round of drinks is on us. This is the mixer for everyone who is passionate about hardware. You’ll find your Internet heroes on hand (think YouTube and electronics podcasts), those going through the grinder of startups exhibiting at the faire, engineers for the giant silicon valley firms, plus all of the hackers who spend their time in basements, garages, and taking over the kitchen table to break something open and make it their own. And of course the Hackaday crew will be on hand, you’ll find [Mike], [Jasmine], [Shulie], [Rich], [Jordan], and [Gerrit] losing our voices as the conversation carries on late into the evening.

The photo at the top of the page is from the 2016 Meetup. This photo is from the 2015 Meetup. Now’s your chance to be the face of the party in next year’s announcement!

Our profoundly awesome sister site, Tindie, is also putting out the call to all hardware artisans (they call themselves Tindarians) to turn out for the meetup. If you’ve never heard of Tindie you’re missing out. And if you’ve never sold your creations there, this meetup is a perfect chance to meet some of the people who do. They’re not just purveyors of bleeding edge hardware, they’re the ones who dream it up and make it happen. You should join their ranks!

We love hackers from all walks of life. But unfortunately, because of the venue for this event, we must limit this to those who are 21 years of age and older. If you can’t get into this event, come find us at the Hackaday/Tindie booth at the Faire.

Other than that, we love to see smiling faces, blinking or moving hardware, and the coolest T-shirt you have in your dresser. Come hang out with Hackaday. You’ll have a most excellent evening if you do. See you Saturday!

Hackaday Links: May 14, 2017

Maker Faire Bay Area is next weekend, and you know what that means: we’re having a meetup on Saturday night. If you’re in the area, it’s highly recommended you attend. It’s a blinky bring-a-hack with booze. You can’t beat it. I heard the OPShark is showing up. All hail the OPShark. You’re gonna want to RSVP if you’re going k thx.

It only took twelve years, but [ladyada] finally got herself on the cover of Make.

Nvidia has the Jetson, an extremely powerful single board computer + GPU meant for machine learning, imagifying, and robotics applications. If you want to do fancy ML stuff with low power devices, I’d highly recommend you check the Jetson out. Of course, the Jetson is only the brains of any Machine Learning robot; you also need some muscle. To that end, Nvidia released the Isaac robotic simulator. It’s a simulator for standard bits of hardware like quadcopters, hovercrafts (?), robotic arms, and yes, selfie drones. What does this mean? Standardized hardware means someone is going to produce 3rd party hardware, and that’s awesome.

This is just an observation, but fidget spinners are just now hitting the mainstream. We didn’t know what they were for a year ago, and we don’t know now.

A Hebocon is a shitty robot battle. DorkbotPDX just had their first Hebocon and the results were… just about as shitty as you would expect. Since this is a shitty robot battle, a MakerBot made an appearance. This robot, SpitterBot, was designed to blow extruded filament all over its opponent. Did the MakerBot win? Yes, SpitterBot won the ‘Poorest Quality’ award.

Supplyframe, Hackaday’s parent company, hosts monthly-ish electronic get-togethers in the San Fransisco office. The focus of these meetups is to find someone cool who built something awesome and get them to talk about it. The March meetup featured [Pete Bevelacqua] who built a Vector Network Analyzer from scratch. The video is worth a watch.

Designing For Fab: A Heads-Up Before Designing PCBs For Professional Assembly

May 10, 2017 by Sonya Vasquez 55 Comments

Designing pcbs for assembly is easy, right? We just squirt all the footprints onto a board layout, connect all the traces, send out the gerbers and position files, and we’re done–right?

Whoa, hold the phone, there, young rogue! Just like we can hack together some working source code with variables named after our best friends, we can also design our PCBs in ways that make it fairly difficult to assemble.

However, by following the agreed-upon design specs, we’ll put ourselves on track for success with automated assembly. If we want another party to put components on our boards, we need to clearly communicate the needed steps to get there. The best way to do so is by following the standards.

Proper Footprint Orientation

Now, for a moment, let’s imagine ourselves as the tip of a vacuum pickup tool on a pick-and-place machine. These tools are designed to pick up components on the reel from their centroid and plunk them on their corresponding land pattern. Seems pretty straightforward, right? It is, provided that we design our footprints knowing that they’ll one day come face-to-face with the pick-and-place machine.

To get from the reel to the board, we, the designers, need two bits of information from out part’s datasheet: the part centroid and the reel orientation.

The part centroid is an X-Y location that calls out the center-of-mass of the part. It basically tells the machine: “pick me up from here!” As designers, it’s our responsibility to design all of our footprints such that the footprint origin is set at the part’s centroid. If we forget to do so, the pick-and-place will try to suck up our parts from a location that may not stick very well to the package, such as: the corner.
