Hackaday’s Open Hardware Summit Experience

Last week was the Open Hardware Summit in Denver Colorado. This yearly gathering brings together the people and businesses that hold Open Hardware as an ideal to encourage, grow, and live by. There was a night-before party, the summit itself which is a day full of talks, and this year a tour of a couple very familiar open hardware companies in the area.

I thought this year’s conference was quite delightful and am happy to share with you some of the highlights.

Building The Hackaday Superconference Badge

The best hardware conference is just a few weeks away. This is the Hackaday Superconference, and it’s two days of talks, an extra day of festivities, soldering irons, and an epic hardware badge. We’ve been working on this badge for a while now, and it’s finally time to share some early details. This is an awesome badge and a great example of how to manufacture electronics on an extremely compressed timetable. This is badgelife, the hardware demoscene of electronic conference badges.

So, what does this badge do? It’s a camera. It has games, and it’s designed by [Mike Harrison] of Mike’s Electric Stuff. He designed and prototyped this badge in a single weekend. On board is a PIC32 microcontroller, an OV9650 camera module, and a bright, crisp 128×128 resolution color OLED display. Tie everything together with a few buttons, and you have a badge that’s really incredible.

So, how do you get one? You’ve got to come to the Hackaday Superconference. This year we’re doing things a bit differently and opening the doors a day early to get the hacker village started with badge hacking topped off by a party that evening and everyone coming to Supercon is invited! This is a badge full of games, puzzles, and video capture and isn’t something to miss. We have less than 30 tickets left so grab your ticket now and read on.

Open Hardware Summit This Thursday

This Thursday, Hackaday and Tindie are going to be rolling into Denver to attend the 2017 Open Hardware Summit.

What’s the big draw for the Open Hardware Summit? The attendees, of course. These are the people who make all the cool bits and bobs in Open Hardware. [Prusa] will be there, Seeed will be there, OSH Park and OSH Stencils will be there (yeah, they’re different companies), BeagleBoard will be there, and Great Scott Gadgets will be there. This is the place you want to be if you want to meet the heroes of Open Hardware.

Of special interest at the Open Hardware Summit this year will be the state of certification talk. Last year, a certification process for Open Hardware was started. If you’re not aware, this is a nearly intractable problem. Copyright covers design files, not implementation, and design patents only cover ornamental fluff on the stuff that actually makes things go. Creating a certification for Open Hardware is exponentially harder than arguing over an Open Source license, and we’re excited to see how the first year of the Open Hardware Certification went.

If you’re going and hanging around in Denver until Friday, there’s a road trip being planned by Sparkfun to visit the awesome companies along the Front Range. The itinerary includes a trip to Sparkfun, lunch at a brewery, and a trip to Lulzbot. Basically, Sparkfun rented a bus. The deadline to RSVP passed long ago, but I’m renting a van for the Hackaday and Tindie crew, and I’m sure there’s going to be some overflow. After the event on Thursday, there will be a Women Who Hack Dinner and Drinks. Hackaday’s evil overlords are graciously providing the drinks and appetizer there.

Teaching Electronics With A Breadboard Badge

Over the last year, the production of homebrew electronic badges for conferences has exploded. This is badgelife — the creation of custom hardware, a trial by fire of manufacturing, and a mountain of blinky LEDs rendered in electronic conference badges. It’s the demoscene for hardware, and all the cool kids are getting into it.

At this year’s World Maker Faire in New York, there was a brand new badge given out by the folks at Consumer Reports. This badge goes far beyond simple swag, and if you take a really good look at it, you’ll see magic rendered in breadboards and wire.

The Consumer Reports breadboard badge is simple and apparently designed to introduce kids to the world of electronics like the old Radio Shack, ‘100-in-1 Electronics Projects’ kits. Unlike most of the ‘beginner badges’ we’ve seen, this isn’t a badge where you only solder a few LEDs and a battery holder to a PCB. This is a breadboard badge. This is hacking with 74-series logic. This is an impressive piece of engineering given away by Consumer Reports. No one saw this one coming. I don’t think anyone at Maker Faire realized there’s now a viable way to create breadboard badges.

Get Hands-On at Supercon: Workshop Tickets Now Available

Build something cool and pick up new skills from the workshops at the Hackaday Superconference. Last week we announced all of the talks you’ll find at Supercon, and starting today you can reserve your spot at one of the workshops.

You must have a Superconference ticket in order to purchase a workshop ticket; buy one right now if you haven’t already. You can get mechanical with Haptics and Animatronics, take your product design from schematic to PCB and enclosure, brush up your embedded development on several choices of platform, make cell towers do your bidding, or dump way too many volts into a block of wood.

Space in these workshops is limited so make sure to sign up before all the seats are taken. The base price for workshops is $10 (basically a “skin in the game” price to encourage those who register to show up). Any tickets priced above that base is meant to cover the material expense of the workshop. Here’s what we have planned:

Embedded Programming with Black Magic and the Lights On

Piotr Esden-Tempski

Sunday Afternoon

Embedded systems programming has earned a bad reputation of being difficult to master. Especially in the open-source world, most people associate it with cut and pasted code that is difficult to debug. The usual tools we have to debug embedded systems are a blinking LED and, if we are lucky, printf statements through a serial port. In this self guided workshop we will show you how easy it can be to have full insight into your microcontroller using fully open source tools that are on par with expensive proprietary closed-source solutions.

Fun with High Voltage

Will Caruana

Sunday Morning

This workshop is about making Lichtenberg figures. A Lichtenberg figure is a piece of art though the multiplication of a few thousands of volts to burn wood. We will cover the science behind this art form as well as the safety and lastly we will be getting hands on experience in being able to using high voltage transformers to make these burnings into wood and make coasters you can take home.

Designing Electronic Textures

Noah Feehan

Sunday Afternoon

Participants will learn the physics behind electrovibration, and then get to play/design for it using a new open-source board called WEFT. After the workshop, you’ll know how to deploy electrovibration in your projects, and understand the feeling of different waveforms.

End to End Product Design with Eagle and Fusion 360

Matt Berggren

Saturday Morning

In this session, we’ll take you end to end, from building a new schematic, simulating a circuit using EAGLE’s built-in SPICE simulator, laying out a PCB, generating mfg files and include some tips & tricks for milling boards and making stencils. We’ll also take you thru the link between electronics and mechanics using Fusion360. Alongside EAGLE we’ll build an enclosure and generate the mfg outputs for your mechanical design (CAM, 3D prints, etc). We’ll look at library management across electronics and mechanics and bidirectional synchronization between both of these domains. This is more than an intro, as Matt’s always good for some essential, oft-missed background and tips with EAGLE you might never have known otherwise.

AVR® MCU Effortless Design Workshop: Prototyping with Sensors and BLE

Bob Martin, Senior Staff Engineer

Sunday Morning

This hands-on training session will walk you through how to develop an embedded sensor node prototype with Bluetooth® Low Energy (BLE) connectivity. You will speed through configuration of the AVR microcontroller, sensor interface and communications interface setup by using Atmel Start, a graphical programming interface. This tool will generate libraries with simple APIs so you can spend time working on your solution instead of messing with registers or communication protocols.

Rapid Prototyping and Linux Kernel Development with the PocketBeagle® Platform

Robert Nelson

Saturday Afternoon

The newly introduced PocketBeagle® is an ultra-tiny-yet-complete Linux-enabled, community-supported, open-source USB-key-fob computer. By leveraging the Octavo SIP, the PocketBeagle offers complete BeagleBoard functionality and includes 512MB DDR3 RAM, 1-GHz ARM Cortex-A8 CPU, 2x 200-MHz PRUs, ARM Cortex-M3, 3D accelerator, power/battery management and EEPROM. The board offers lots of GPIOs, on board peripherals and various expansion capabilities via multiple headers and the Mikroelektronika click board interface. During this course you will learn about pin configuration, how to create a Linux distribution, reconfiguring io on the fly and how to leverage expansion modules. Attendees will leave with their very own PocketBeagle and a couple other surprises as well.

Cellular Connectivity for Your Next Hardware Project

Ben Strahan and Chris Gammell

Saturday Afternoon

Your project shouldn’t be constrained by the range of a WiFi signal. This workshop will show you how to connect to cellular towers via a serial link, get connected into the cloud and reliably start transmitting data. This workshop is suitable for people just getting started in the firmware ecosystem up through advanced firmware engineers. Advanced members of the workshop will have the opportunity to hack their conference badge to connect to cell towers. Sign up for this workshop to add another connection method to your hardware development toolbox.

An Introduction to Animatronics with Laser Cut Tentacle Mechanisms

Joshua Vasquez

Saturday Morning

Animatronics are way cool, but the hacker community rarely ventures farther than a few hobby servos and “dem-blinkin’ LEDs.” In this workshop, I’ll get you cozy with tentacle mechanisms that you can build with just a laser cutter and a few hand tools. There are three big takeaways from this workshop. We’ll build up a two-stage controller reusable in other projects, muscle up our vocabulary of off-the-shelf parts for cable mechanisms, and discover a few laser-cut design techniques.

Superconference workshops tend to sell out extremely quickly. Don’t wait to get your ticket.

All the Speakers Plus We’re Heating It Up a Day Early

Things are getting real now. Check the list below for the last round of confirmed speakers to the 2017 Hackaday Superconference. This brings our slate of speakers to 32, but we’re not done yet.

Hackaday is adding an extra day to the Superconference by starting the festivities on Friday. Again this year we have an excellent custom hardware badge in development. It’s hard to pull yourself away during the Supercon for badge hacking so this year you can check in on Friday and let the hacking begin. Since you’ll be in town early, we’re also throwing a party at Supplyframe office (minutes walk from the main venue) for all Supercon speakers and attendees.

But we’re still not done. 32 talks, an epic hardware badge, and an extra day of festivities, what else could there be you ask? Two things: workshops and the Hackaday Prize party. Supercon will play host to eight hardware workshops this year. We’ll announce workshop presenters and topics next week but I can tell you they’re superb this year!

Laser Smoothies At Maker Faire

This year at Maker Faire, laser cutters were all the rage. Dremel announced a 40W laser cutter, but it won’t be available for purchase until this time next year, there is no price yet, and therefore doesn’t deserve further mention. Glowforge was out in full force, but the most interesting aspect of the Glowforge — a compact filter system that sits right underneath the laser — was not to be found. It looks like lasers are the next 3D printer.

Of course, those in the know have already been using laser cutters for years, and there are options for desktop CO2 laser cutters that cost less than a kilobuck. I speak, of course, of the ubiquitous K40 laser, a machine you can get off of eBay or AliExpress for the price of a generic, off-brand 3D printer. There is a downside to the K40, though: the control electronics and software are notoriously terrible. Fix that, though, and you have something really spectacular.

The Cohesion3D Mini

This year at Maker Faire, [Ray Kholodovsky] of Cohesion3D brought out his Smoothie-derived control boards for CNC machines and laser cutters. Of note is his K40 upgrade that turns the eBay special laser cutter into a 32-bit professional machine. This is the cheapest way to start lasing in your workshop.

We saw [Ray] at the Faire last year when he was demoing his Smoothie-derived boards for 3D printers and CNC machines. These are tiny, relatively low-cost boards that use Smoothieware, an Open Source, 32-bit CNC control system that is extremely extensible and very powerful. Basically, if you’re building a normal, ordinary DIY 3D printer, a RAMPS or RAMBO will do. If you’re doing something weird, like a 3D printer with strange kinematics, a 5-axis milling machine, or you’d like awesome engraving on a laser cutter, Smoothie is the way to go.

The stock board found in a K40 (left) and the Cohesion3D Mini (right). The Cohesion3D Mini is a drop-in replacement for the stock K40 board.

The Cohesion3D board is a direct, drop-in replacement for the control board found in the K40 laser. Since all of the K40 laser cutters are the same, and they’re really only a power supply and a CNC gantry, this is the one-stop-shop of K40 upgrades. The terrible electronics are gone, you don’t have to use Corel, and for a hundred bucks, you have something resembling a professional laser cutter.

The K40 laser has been around for several years now, but only recently have a few very interesting hacks and mods come out that push this blue light special laser cutter into semi-professional territory for people willing to get their hands dirty. A few months ago [Scorch] published K40 Whisperer, a piece of software that makes the stock electronics tolerable and able to accept normal SVGs and DXFs. The K40 has also been modified for a larger bed, and LaserWeb has been handling the software side of things for about two years now. Things are looking great for the K40 hacking scene, and Hackaday already has a, ‘I just bought a K40, now what?’ series in the works. Things are looking up for cheap laser cutters, and a Smoothie upgrade is just the cherry on top.
