Apple 1 Emulator Is A Perfect Fit For Supercon Badge

November 13, 2018 by 9 Comments

Supercon badge hackers had to be ready to present their show-and-tell by 6 pm Sunday evening. This ruthless unmoving deadline meant every badge hack on stage represents an accomplishment in time management, and some luck, in addition to their own technical merits. But that deadline also meant a few fantastic projects lost their race against the clock. We were rooting for [Jac Goudsmit] to build an Apple I emulator as his badge expansion, but he wasn’t quite done when our badge hack ceremony began. After Supercon he went home, finished the project, and documented everything in a detailed writeup.

Our 2018 Supercon badge is built on a retro-computing theme, and the default firmware came with a BASIC interpreter as well as a Z80 emulator running CP/M. So an Apple 1 emulator should feel right home with its contemporaries. Mechanically speaking, all the parts were a tight fit on the badge expansion board given out to every attendee at Supercon. So tightly that [Jac] had to file down the two main chips in order to fit them side by side. The breadboard-like pattern of connected holes on the expansion board, intended to help ease in beginners for their badge hack soldering, proved to be an inconvenience in tightly packed arrangements such as this.

With all the work [Jac] had invested, it was heartbreaking to know he was only five minutes of soldering and 30 minutes of coding away when time ran out. Time pressure was part of the challenge faced by every Supercon badge hacker, and while we’re sad [Jac] missed the deadline for stage time we’re happy to see him finish and write it all up. We hope every badge hacker would write up their stories of frantic weekend projects. Those who do so on hackaday.io are encouraged to tag their project with “Supercon” and get them added to our list of badge hacks for everyone to admire.

Supercon Badge Hackers Racing The Clock

November 6, 2018 by 8 Comments

At the end of Hackaday Superconference weekend, we hold a badge hacking ceremony on the main stage where anyone who has done anything with their badge is invited to come on stage and show off their work. Yes, even if it’s just a blinking LED! It was a tremendous pleasure to see not only people taking us at our word and presented blinking LEDs, but that the community in the room welcomed these inductees to hardware hacking with cheers. Before the ceremony, though, there was a lot of frantic work by badge hackers armed with soldering irons and fueled by caffeine. It’s always amazing how much people can accomplish in a single focused weekend.

Green LED Means GO For Supercon Badge Hacking

November 4, 2018 by 1 Comment

In addition to great speakers and enlightening workshops at Supercon, we have an area set aside for attendees to hack on their conference badges. There is no prerequisite beyond having a badge and a willingness to get hands-on. From hardware beginners to professional embedded system developers, we welcome all skill levels!

The image above is a free-form LED light sculpture by [4C1dBurn], who had just learned to solder and this is how a new skill was put into practice. In the background is the badge hacking arena: 7 tables set up in a row with 6 seats per table. The doors opened at 9AM and almost all the seats were filled by 9:30AM. There’s a constant flow as people leave to attend a talk or workshop, and others arrive to fill the vacancy.

In our hardware hacking overview, we shared an example of an LED array controlled by badge using shift registers. Several badge hackers built on top of this idea. [X] is making a version for surface mount LEDs, and [macegr]’s variant incorporated an USB-to-serial adapter on board to reduce wire clutter. He calls it a “quality of life improvement” and we think it’s brilliant.

Any reduction in wire clutter can only help with the many glorious explosions of wires scattered about. This particular example is a work-in-progress by [carfucar] turning a badge into wireless remote for a large array of WS2812B LED strips.

Heeding our call to action in the hardware hacking overview, there are at least two efforts underway to add wireless communication capability to the badge. [Preston] is making good progress teaching a badge to talk to an AVR-IoT module. [morgan] and [Ben] are building a mesh network using ESP32s. If it gets up and running, they’ve brought a bunch of ESP32s to add more nodes to their network.

For the talks currently on stage, go to the Supercon event page and click “Livestream” in the upper right corner for the official live stream. Badge hacking will continue all through Supercon, parts of which will be visible through unofficial livestream of badge hacking from attendees like [X]’s robot [Sharon].

Vinduino Water-Smart Farming – Now With LoRa!

October 25, 2018 by 9 Comments

Our five rounds of Hackaday Prize 2018 challenges have just wrapped up, and we’re looking forward to see where the chips fall in the final ranking. While we’re waiting for the winners to be announced at Hackaday Superconference, it’s fun to take a look back at one of our past winners. Watch [Reinier van der Lee] give the latest updates on his Vinduino project (video also embedded after the break) to a Hackaday Los Angeles meetup earlier this year.

Vinduino started with [Reinier]’s desire to better understand what happens to irrigation water under the surface, measuring soil moisture at different depths. This knowledge informs more efficient use of irrigation water, as we’ve previously covered in more detail. What [Reinier] has been focused on is improving usability of the system by networking the sensors wirelessly versus having to walk up and physically attach a reader unit.

His thought started the same as ours – put them on WiFi! But adding WiFi coverage across his entire vineyard was not going to be cost-effective. After experimenting with various communication schemes, he has settled on LoRa. Designed to trade raw bandwidth for long range with low power requirements, it is a perfect match for a network of soil moisture sensors.

In the video [Reinier] gives an overview of LoRa for those who might be unfamiliar. Followed by results of his experiments integrating LoRa functionality into Vinduino, and ending with a call to action for hackers to help grow the LoRa network. It sounds like he’s become quite the champion for the cause! He’s even giving a hands-on workshop at Supercon where you can build your own LoRa connected sensor. (Get tickets here.)

We’re always happy to see open-source hardware projects like Vinduino succeed, transitioning to a product that solve real world problems. We know there are even more promising ideas out there, which is why Hackaday’s sister company Tindie is funding a Project to Product program to help this year’s winners follow in Vinduino’s footsteps. We look forward to sharing more success stories yet to come.

Mike Harrison At The Superconference: Flying LCD Pixels

December 11, 2017 by 18 Comments

Mike Harrison, perhaps better known to us as the titular Mike of YouTube channel mikeselectricstuff, is a hardware hacking genius. He’s the man behind this year’s Superconference badge, and his hacks and teardowns have graced our pages many times. The best thing about Mike is that his day job is designing implausibly cool one-off hardware for large-scale art installations. His customers are largely artists, which means that they just don’t care about the tech as long as it works. So when he gets together with a bunch of like-minded hacker types, he’s got a lot of pent-up technical details that he just has to get out. Our gain.

He’s been doing a number of LCD installations lately. And he’s not using the standard LCD calculator displays that we all know and love, although the tech is exactly the same, but is instead using roughly 4″ square single pixels. His Superconference talk dives deep into the behind-the-scenes cleverness that made possible a work of art that required hundreds of these, suspended by thin wires in mid-air, working together to simulate a flock of birds. You really want to watch this talk.

The Hacker Village Of Supercon

November 16, 2017 by 9 Comments

I’m utterly exhausted and still in a state of awe. The Hackaday Superconference has grown in so many ways, but one thing remains the same: the spirit of the Hacker Village — an intangible feeling that grows up around all who attend — is bliss to take part in.

There’s really no substitute for having been there in person. I’ll go into detail below and try to share the experience as best I can. But the gist of the atmosphere is this: everyone at Supercon is the type of person you’d want to be stuck in a rowboat with, or partnered with on an engineering project, or to have next to you while trying to save the world. There are no looky-loos at Supercon. It turns out we are all stuck in a rowboat together, we are all working on engineering projects, and we are all trying to save the world. And when we all get together it feels like a drug our pragmatic minds never knew existed. This is the recharge for that sense of urgency that keeps you going all year long.

So yes, you really missed it. But start now. Become friends with all of these people over the next year. Begin building your Supercon community now and it’ll feel like a reunion when it rolls around again next November.

Huge Names Confirm Their Supercon Appearances

September 20, 2017 by 16 Comments

We’re excited to announce the next batch of speakers for the 2017 Hackaday Superconference.

We are especially pleased to welcome Michael Ossmann as a speaker. He presented an RF design workshop at the 2014 Superconference which was sold out, standing room only, and still turned away dozens of people before becoming a hit on the Internet. This year he takes the stage with colleague Dominic Spill as they focus on infrared communications and the uses and abuses of such.

Dr. Christal Gordon threw down an incredible talk on biologically inspired sensors last year and we suspect she will outdo herself this year. Her talk will cover the fanciest of cutting-edge sensors and the trade-offs of selecting the new hotness for your designs. Coming out of this you will know when to go with a suite of tried and true components and when to make the leap to new tech.

Several of this year’s Hackaday Prize Judges will be on hand and presenting talks. In addition to Christal Gordon and Danielle Applestone (announced as a speaker last week), we’re thrilled to have Anouk Wipprecht — internationally known for her work in fashion and engineering, pushing the boundaries of how technology can interface with humans — as a speaker. Nadya Peek from the Center for Bits and Atoms who spoke at Supercon in 2016 with a harrowing tale of an impromptu engineering challenge in Shenzhen has confirmed that she will speak this year.

The ever-popular Sprite_TM will be at Supercon. He has a reputation for bringing the house down with fantastic presentations, be it the Tamagochi Matrix or the Tiniest Game Boy. And we are proud to present the Art Director for Hackaday — Joe Kim will be speaking about the curious connection between art and technology and how developments in one push the other forward.

Ever wonder about the air you’re breathing in the house or at work. So does Natalia Mykhaylova whose work begins to monitor and catalog that information. She will discuss the state of our HVAC systems and what it looks like to bring them into the information age.

Below you’ll find the confirmed speakers we’re announcing today. We’ll have more, as well as a list of confirmed talks next week. Get your ticket now, they will sell out.
