World Create Day Is The Hackaday Event In Your Neighborhood

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.

Retrotechtacular: The Best Jeep Commercial Ever

How often do we find ourselves thankful for advertising? When it comes to Hackaday’s Retrotechtacular column it’s actually quite often since it snapshots a moment in culture and technology. Today’s offering is a shining example, where we get a great look into vehicular utility of the day that is rarely seen in our modern lives.

The origin story of the Jeep is of course its prominence in World War II when more than half a million were produced. GIs who drove the vehicles constantly during the war greatly appreciated the reliability and versatility and wanted one for their own when returning home and a market rose up to satisfy that need. The modern equivalent would be the Hummer fad that started in the 1990’s. Humvee, the early ancestor of the Hummer, replaced the Jeep in the US military in the 1980’s and a version called Hummer entered the consumer market in ’92. But that was more of a comfort-meets-icon proposition, where the Jeep of the 1950’s (seen in the commercial below) delivered — even over delivered — on a promise of utility.

In this ad, the case is made for Jeep as farm implement, acting as plow, mower, even post hole digger. As a firefighting implement the announcer boasts that “One man with a Jeep can do the work of 100 men with shovels” by cutting fire breaks into the soil. It’s sold as the workhorse of cemeteries, ranches, county service crews, and anything else their marketing gurus could write into copy. We think the metrics are dubious but certainly the inexpensive build, versatile nature, and need for power equipment across the countryside brought these Jeeps into widespread rural and industrial service in myriad roles.

Power take off driving shaft to power circular saw. You can also see the hydraulics that lift and lower the saw.

What makes most of this possible is the existence of a power take-off (PTO). This is a mechanical connection from the engine of the vehicle to external components that can be switched out. Once connected, the speed of the engine can be controlled to adjust the power take-off operation. In conjunction with a hydraulic system that can lift and lower the implement, it becomes a remarkably versatile system. We begin to wonder the American vernacular includes the saying “it’s like the Swiss Army knife of…” rather than calling everything that’s insanely useful a Jeep.

Connect a pump to the PTO and you have a fire-fighting Jeep. Connect a generator and you can drive electric tools like the chainsaw used to cut down a tree in the video and to power an arc welder. There’s a gnarly-looking circular saw blade, and you’re going to spill your coffee when you get to the “Jeep-a-trench”. That’s right, a trenching attachment gives the vehicle’s suspension a rough workout. It boasts the ability to dig down six feet and complete the footings for an ordinary house in just three hours.

Willy’s MB, the company behind the Jeep must have employed a crew of hackers. What a blast it would have been to be in the research and development sessions to come up with 1,001 more uses for the equipment. The company has a bit of Jeep history you can peruse, but we’d really love to hear about the addon equipment ideas that didn’t make the cut. Are there any readers who have some stories along these lines? Let us know in the comments below.

Hackaday Dublin Unconference: Grab Your Tickets!

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!

The Most Utilitarian 3D Print Has The Widest Reach

3D Printing is often heralded as a completely new fabrication method, creating things that simply cannot be manufactured in other ways. While this is true, the widest reaching usefulness of 3D printers isn’t for pushing the limits of fabrication. The real power is in pushing the limits of manufacturing for individuals who need one-off parts.

The proof point is in the story shown above. A missing key on a keyboard could have meant an otherwise fine piece of hardware headed for recycling, but was saved by a single part printed on a desktop 3D printer. Multiply this by the increasing number of people who have access to these printers and you can see how using 3D printing for repairs will have a huge impact on keeping our gear in service longer.

We want to see how you’ve saved things from the rubbish pile. Show them off in Hackaday’s Repairs You Can Print contest. The best Student entry and the best Organization entry (think Hackerspace) will each win a high-end 3D Printer. But anyone can enter, with the top twenty entries receiving $100 credit for Tindie.

If you’re like us though, these prizes are just icing on the cake. The real reward is showing what some think is mundane but the Hackaday crowd believes is worth celebrating. Check out all the entries so far and join us below for a few highlights.

Early Bird Tickets For Hackaday Belgrade

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!

Membership Ring Of The Electronic Illuminati

When the cabal of electronic design gurus that pull the invisible strings of the hardware world get together, we imagine they have to show this ring to prove their identity. This is the work of [Zach Fredin], and you’re going to be shocked by the construction and execution of what he calls Cyborg Ring.

The most obvious feature of the Cyborg Ring is the collection of addressable LEDs that occupy the area where gems would be found on a ring. What might not be so obvious is that this is constructed completely of electronic components, and doesn’t use any traditional mechanical parts like standoffs. Quite literally, the surface mount devices are structural in this ring.

They are also electrical. Here you can see a detail of how [Zach] pulled this off. We are looking at the underside of the ring, the part that goes below your knuckle. One of the two PCBs that are sized to fit your finger has been placed in a Stick Vise while the QFN processor is soldered on end, and the pairs of SMD resistors are put in place.

The precise measurements of each part make it possible to choose components that will perfectly span the gap between the two boards. In the background of the image you can see SMD resistors on their long ends — a technique he used to allow the LEDs themselves to span between one resistor on each of the two PDBs to complete the circuit. Incredible, right?

But it gets better. [Zach] ended up with a working prototype, but has continued to forge ahead with new design iterations. These updates are a delight to read! Make sure you follow his project and check in regularly; if you’ve already looked at this now’s the time to go back and see the new work. The gold pads for the minuscule coin cells which power the ring are being reselected as the batteries didn’t fit well on the original. Some layout problems are being tweaked. And the new spin of boards should be back from fab in a week or so.

Don’t miss the demo video found below. We really like seeing projects that build within the wearble ring form factor. It’s an impressive constraint which [Zach] seems to have mastered. Another favorite of ours is [Kevin’s] Arduboy ring.

Making The Case For Open Source Medical Devices

Engineering for medical, automotive, and aerospace is highly regulated. It’s not difficult to see why: lives are often at stake when devices in these fields fail. The cost of certifying and working within established regulations is not insignificant and this is likely the main reason we don’t see a lot of work on Open Hardware in these areas.

Ashwin K. Whitchurch wants to change this and see the introduction of simple but important Open Source medical devices for those who will benefit the most from them. His talk at the Hackaday Superconference explores the possible benefits of Open Medical devices and the challenges that need to be solved for success.
