World Create Day Is The Hackaday Event In Your Neighborhood

February 26, 2018 by Mike Szczys 10 Comments

Hackaday World Create Day is on March 17th and it’s happening near you. Get together with hackers in your area and create something. Sign up now to host a World Create Day gathering! These are really easy to organize, but we can only do it with your help.

The Hackaday community from around the world will meetup and spend time building together on Saturday, March 17th. Pick one of those projects you’ve been meaning to dive into and get together with some old and new friends to hack on your projects together.

You should make this day your own. As with any hands-on hacking events it’s a good idea to block out a bit of time at the end for lightning talks to show off the builds everyone has been working on. Make the memories live on past a single day by taking pictures and posting the story of your World Create Day meetup. We enjoyed getting a great look at many of last year’s meetups this way and want to expand the builds we feature on the front page this year.

Meetup Organizers Wanted

Fill out this form to let us know you want to host a meetup.

Every year we have World Create Day meetups all over the world which are set up by local organizers. Many of those will happen again this year, but we also need you to organize an event in your area. We’ll help you get things set up and put your event up on the big map so others in your area will plan to join in. Do it now, if we get your shipping info early we’ll send you stickers and other swag to hand out at your gathering.

Build Something that Matters

The core of World Create Day is to stop making excuses and just build something. Great builds start with a plan. The Hackaday Prize will begin soon, and since you’re already getting together with other people, form a team and dream up your entry.

This is your take on building something that matters to the world. Come up with a plan that solves a problem facing humanity and publish your work on Hackaday.io. You may be surprised by the support you get for your idea, but you’ll never know until you put an idea out there. Join in Hackaday’s World Create Day on March 17th and let’s show the world the kind of hope that blossoms when we decide to build something that matters.

Rapidly Prototyping Prosthetics, Braille, And Wheelchairs

February 23, 2018 by Anool Mahidharia 4 Comments

We live in an amazing time where the availability of rapid prototyping tools and expertise to use them has expanded faster than at any other time in human history. We now have an amazing ability to quickly bring together creative solutions — perfect examples of this are the designs for specialized arm prosthetics, Braille printing, and custom wheelchair builds that came together last week.

Earlier this month we published details about the S.T.E.A.M. Fabrikarium program taking place at Maker’s Asylum in Mumbai. The five-day event was designed to match up groups of makers with mentors to build assistive devices which help improve the condition of differently-abled people.

The participants were split into eight teams and they came up with some amazing results at the end of the five-day program.

Hands-On: Prosthetic Designs That Go Beyond

Three teams worked on projects based on Bionico – a myoelectric prosthesis

DIY Prosthetic Socket – a Human Machine Interface : [Mahendra Pitav aka Mahen] lost his left arm during the series of train bomb blasts in Mumbai in 2006, which killed 200 and injured over 700 commuters. He uses a prosthetic arm which is essentially a three-pronged claw that is cable activated using his other good arm. While it is useful, the limited functionality restricted him from doing many simple things. The DIY Prosthetic socket team worked with [Mahen] and [Nico Huchet] from MyHumanKit (who lost his right arm in an accident 16 years back), and fabricated a prosthetic forearm for [Mahen] with a modular, 3D printed accessory socket. Embedded within the arm is a rechargeable power source that provides 5V USB output at the socket end to power the devices that are plugged in. It also provides a second port to help recharge mobile phones. Also embedded in the arm was an IR reflective sensor that can be used to sense muscle movements and help trigger specific functions of add-on circuits, for example servos.

Hackaday Dublin Unconference: Grab Your Tickets!

February 18, 2018 by Mike Szczys 20 Comments

Hackaday comes together in Ireland on April 7th and we want you to be there. Get your free ticket right now for the Hackaday Dublin Unconference!

An Unconference is the best way to put your finger on the pulse of what is happening in the hardware world right now. Everyone who attends should be ready to stand and deliver a seven-minute talk on something that excites them right now — this means you. The easiest thing to do is grab your latest hack off the shelf and talk about that.

Talks may be about a prototype, project, or product currently in progress at your home, work, or university. It could also be an idea, concept, or skill that you’re now exploring. The point is to channel your excitement and pass it on to others in a friendly presentation environment where everyone will cheer as your story unfolds.

Hackaday hosted an excellent Unconference in London back in September to a packed house for dozens of amazing presentations on a huge range of topics. We heard about bicycle turn signals, laser enhancing NES zappers, telepresence robots with IKEA origin stories, tiny-pitch LED matrix design, driving flip-dot displays, not trusting hardware 2-factor, and much more.

All the tickets for that event were scooped up in a few hours, and a huge waitlist followed. Don’t wait to grab your ticket!

We’re so happy to partner with DesignSpark, the exclusive sponsor of the Hackaday Dublin Unconference. DesignSpark is the innovation arm of RS Components and will have some staff on hand at the Unconference. They share our excitement in bringing together the Hackaday community throughout Europe. It is with their support that we are able to book an incredible venue and offer admission at no cost to all attendees. Hackaday events fill to capacity quickly, so get your ticket now before they are gone.

This Unconference is being held at Project Arts Centre, right at the heart of the Temple Bar area in central Dublin. The performing arts space has comfortable seating and is perfect for our presentation format. We’ll get started at 13:00. Tea, coffee, and snacks will be served throughout the afternoon and we’ll provide dinner as well. Anyone who is still standing when we close the doors at 21:00 is invited to join us at the pub afterward (we’ll get the first round).

As always, Hackaday’s success is based on the community of hackers, designers, and engineers that make it up. Please share the link to tickets on your social media and pester your friends to attend. Most importantly, don’t shy away from this speaking opportunity. We want to hear your story and this is the place to tell it. See you in Dublin in just a few short weeks!

Great Beginnings For Vintage Computing In Seattle; VCF PNW

February 17, 2018 by Dan Maloney 27 Comments

The pitch to my wife was simple: “Feel like spending the weekend in Seattle?” That’s how I ended up at the inaugural Vintage Computer Festival Pacific Northwest last weekend, and I’m glad we made the five-hour drive into The Big City to check it out. Hackaday is a VCF sponsor, after all, so it seemed like a great excuse to make the trip. That it ended up being two consecutive days of great Seattle weather was only icing on the cake of being able to spend time with fellow retro computer aficionados and their dearest bits of old hardware, in a great museum dedicated to keeping computer history alive and accessible.

The fact that Seattle, home of Microsoft, Amazon, and dozens of other tech companies, has until now been left out of the loop in favor of VCF East in New Jersey and VCF West in Mountain View seems strange, but judging by the reception, VCF PNW is here to stay and poised to grow. There were 20 exhibitors for this go around, showing off everything from reanimated PDP-11 and Altair 8800 control panels to TRS-80s from Model 1 through to the CoCo. Almost every class of reasonably transportable retro hardware was represented, as well as some that pushed the portability envelope, like a working PDP-8 and a huge Symbolics 3640 LISP workstation.

Early Bird Tickets For Hackaday Belgrade

February 12, 2018 by Mike Szczys 11 Comments

Early Bird tickets for Hackaday Belgrade have just gone on sale, but they will not last long. This is Hackaday’s premier European hardware conference with talks, workshops, great food and drink, entertainment, and a hardware badge for hacking and demos. Festivities will go all day on 26 May and carry long into the night. The last time we did this was two years ago and it was completely sold out — now’s the time to get in on the fun.

Who’s speaking, what are the workshops all about, what does the hardware badge do, and what music do you have lined up? Trust your gut — we’ll have more details soon enough but you know this conference will be epic and it’s worth your time and treasure to be there. To reward your enthusiasm, Early Bird tickets are a much better deal than general admission.

Our Call for Proposals is now open. We seek talks and workshops exploring the most interesting uses of technology and the culture that goes along with it.

The Circle of Friends You May Not Have Met

You know those people just outside of the Hackaday orbit who are tired of hearing about the stuff you build and the coding tricks you discover? Those people won’t be there. Everywhere you turn at Hackaday Belgrade, fascinating conversations await. You’ll want it to last a week but it’s just one day… plus a little more.

Plan to arrive in Belgrade on Friday. There will be an unofficial meetup at a bar (last time we took over most of the place). The weather in Springtime is amazing and having pivo on the porch until far too late in the evening was a blast.

Hackaday Belgrade Badge prototype. Voja Antonic, creator of the Galaksija computer — now in museums around the world — just Tweeted this teaser image of the conference badge design.

Things get started, not too early, on Saturday around 10 AM, and we’ll have coffee and treats to kick off the day. The baristas in 2016 were incredible, and the food — lunch and dinner — were as well. These amenities ring the socializing area of the conference in the lobby of the main hall. Talks and workshops will go all day but at 7 PM it’s all about hacking while our crew lay down a live IDM set. At 11 PM the badge hacking demos begin and the live DJ steps up at midnight.

See the Sights

Don’t let things end there. I vaguely remember a 3 or 4 AM ćevapi run after the last Hackaday Belgrade conference, and there were multiple groups planning museum trips the next day. Belgrade has a wonderful Museum of Science and Technology (I made it to that one), a Nikola Tesla Museum (I’m planning to get there this time), and a multitude of interesting attractions. I’ll save you from having to see my gallery of food photos, but the city is fun, inexpensive, and has really delicious cuisine.

This is a weekend you’ll remember forever. Make your plans now!

You Can Learn A Lot From A Blinkenrocket

February 2, 2018 by Elliot Williams 8 Comments

At this year’s Chaos Communication Congress, we caught up with [muzy] and [overflo], who were there with a badge and soldering project they designed to teach young folks how to solder and program. Blinkenrocket is a basically a 64-LED matrix display and just enough support hardware to store and display animations, and judging by the number of blinking rockets we saw around the necks of attendees, it was a success.

Their talk at 34C3 mostly concerns the production details, design refinements, and the pitfalls of producing thousands of a thing. If you’re thinking of building a hardware kit or badge on this scale, you should really check it out and crib some of their production optimization tricks.

For instance, instead of labelling the parts “C2” or “R: 220 Ohms”, they used a simple color-coding scheme. This not only makes it easier for kids to assemble, but it also means that they didn’t have to stick 1,000 part labels on every component. Coupled with [overflo]’s Zerhacker, SMD parts in strips were cut to the right length and color-coded in one step, done by machine.

The coolest feature of the Blinkenrocket itself is the audio programming interface. It’s like in the bad old days of software stored on cassette tapes, but it’s a phenomenal interface for getting a simple animation out of a web app and straight into a piece of minimal hardware — just plug it into a laptop or cell phone’s audio out and press “play” in the browser. The original design tried to encode the data in the pulse-length of square waves, but this turned out to be very hardware dependent. The final design used frequency-shift keying. What’s old is new again.

Everything you could want to know about the design, its code, and even the website itself are up on the project’s GitHub page, so go check it out. If you’d like to arrange a Blinkenrocket workshop yourself, shoot [muzy] or [overflo] an e-mail. Full disclosure: [overflo] gave us a kit, the “hard-mode” SMD one with ~~0805~~ 1206 parts, and it was fun to assemble and program.
