Retrotechtacular: Junior Missile Men Of The 1960s

November 22, 2021 by Dan Maloney 30 Comments

Just like the imaginative kids depicted in “Junior Missile Men in Action,” you’ll have to employ a fair bit of your own imagination to figure out what was going on in the original film, which seems to have suffered a bit — OK, a lot — from multiple rounds of digitization and format conversion. [GarageManCave] tells us he found the film on a newsgroup back in the 1990s, but only recently uploaded it to YouTube. It’s hard to watch, but worth it for anyone who spent hours building an Estes model rocket and had that gut-check moment when sliding it onto the guide rail and getting it ready for launch. Would it go? Would it survive the trip? Or would it end up hanging from a tree branch, or lost in the high grass that always seemed to be ready to eat model rockets, planes, Frisbees, or pretty much anything that was fun?

Model rocketry was most definitely good, clean fun, even with the rotten egg stink of the propellant and the risk of failure. To mitigate those risks, the West Covina Model Rocket Society, the group the film focuses on, was formed in the 1960s. The boys and girls pictured had the distinct advantage of living in an area where many of their parents were employed by the aerospace industry, and the influence of trained engineers shows — weekly build sessions, well-organized range days, and even theodolites to track the rockets and calculate their altitude. They even test-fired rockets from miniature silos, and mimicked a Polaris missile launch by firing a model from a bucket of water. It was far more intensive and organized than the early rocketry exposure most of us got, and has the look and feel of a FIRST robotics group today.

Given the membership numbers the WCMRS boasted of in its heyday, and the fact that model rocketry was often the “gateway drug” into the hacking lifestyle, there’s a good chance that someone in the Hackaday community got their start out in that park in West Covina, or perhaps was even in the film. If you’re out there, let us know in the comments — we’d love to hear a first-hand report on what the club was like, and how it helped you get started.

Space Age Road Rage: Right Of Way Above The Karman Line

October 13, 2021 by Ryan Flowers 35 Comments

On a dark night in 2006 I was bicycle commuting to my office, oblivious to the countless man made objects orbiting in the sky above me at thousands of miles per hour. My attention was instead focused on a northbound car speeding through a freeway underpass at dozens of miles per hour, oblivious to my southbound headlamp. The car swerved into the left turn lane to get to the freeway on-ramp. The problem? I was only a few feet from crossing the entrance to that very on-ramp! As the car rushed through their left turn I was presented with a split second decision: slow, and possibly stop in the middle of the on-ramp, or just go for it and hope for the best.

A graphic depicting a dawdling bicycle rider about to be in the way of a speeding car driver — In Blue: Terrified cyclist. In Red: A speeding car careening around a corner without slowing down.

By law I had the right of way. But this was no time to start discussing right of way with the driver of the vehicle that threatened to turn me into a dark spot on the road. I followed my gut instinct, and my legs burned in compliance as I sped across that on-ramp entrance with all my might. The oncoming car missed my rear wheel by mere feet! What could have ended in disaster and possibly even death had resulted in a near miss.

Terrestrial vehicles generally have laws and regulations that specify and enforce proper behavior. I had every right to expect the oncoming car be observant of their surroundings or to at least slow to a normal speed before making that turn. In contrast, traffic control in Earth orbit conjures up thoughts of bargain-crazed shoppers packed into a big box store on Black Friday.

So is spacecraft traffic in orbit really a free-for-all? If there were stringent rules, how can they be enforced? Before we explore the answers to those questions, let’s examine the problem we’re here to discuss: stuff in space running into other stuff in space.

Hackaday Links: April 19, 2020

April 19, 2020 by Dan Maloney 29 Comments

While the COVID-19 pandemic at least seems to be on a downward track, the dystopian aspects of the response to the disease appear to be on the rise. As if there weren’t enough busybodies and bluenoses shaming their neighbors for real or imagined quarantine violations on social media, now we have the rise of social-distancing enforcement drones. These have been in use in hot zones around the world, of course, but have only recently arrived in the US. From New Jersey to Florida, drones are buzzing about in search of people not cowering in fear in their homes and blaring messages about how they face fines and arrest for seeking a little fresh air and sunshine. We’re all in favor of minimizing contact with potentially infected people, but it seems like these methods might be taking things a bit too far.

If you somehow find yourself with some spare time and want to increase your knowledge, or at least expand your virtual library, Springer Publishing has some exciting news for you. The journal and textbook publisher has made over 400 ebook titles available for free download. We had a quick scan over the list, and while the books run the gamut from social sciences to astrophysics, there are plenty of titles that are right in the wheelhouse of most Hackaday readers. There are books on power electronics, semiconductor physics, and artificial intelligence, as well as tons more. They all seem to be recent titles, so the information isn’t likely to be too dated. Give the list a once-over and happy downloading.

Out of all the people on this planet, the three with the least chance of being infected with SARS-CoV-2 blasted off from Kazakhstan this week on Soyuz MS-16 to meet up with the ISS. The long-quarantined crew of Anatoly Ivanishin, Ivan Vagner, and Chris Cassidy swapped places with the Expedition 62 crew, who returned to Earth safely in the Soyuz MS-15 vehicle. It’s a strange new world they return to, and we wish them and their ISS colleagues all the best. What struck us most about this mission, though, was some apparently surreptitiously obtained footage of the launch from a remarkably dangerous position. We saw some analysis of the footage, and based on the sound delay the camera was perhaps as close as 150 meters to the launchpad. It’s hard to say if the astronauts or the camera operator was braver.

And finally, because neatness counts, we got this great tip on making your breadboard jumpers perfectly straight. There’s something satisfying about breadboard circuits where the jumpers are straight and exactly the length the need to be, and John Martin’s method is so simple you can’t help but use it. He just rolls the stripped jumpers between his bench and something flat; he uses a Post-it note pad but just about anything will do. The result is satisfyingly straight jumpers, ready to be bent and inserted. We bet this method could be modified to work with the stiffer wire normally used in circuit sculptures like those of Mohit Bhoite; he went into some depth about his methods during his Supercon talk last year, and it’s worth watching if you haven’t seen it yet.

2017 Hackaday Prize Begins Right Now

March 20, 2017 by Mike Szczys 75 Comments

Today the 2017 Hackaday Prize begins!

This is Hackaday’s global engineering initiative that encourages people to direct their skill and energy to make the world a better place. We call it the Hackaday Prize, but it’s far more than that. Join a community of talented people who enrich their own lives by seeking out new challenges and new technologies, then pioneers a way to combine them to Build Something that Matters. Show us your build by starting a Hackaday.io project page and enter today!

You Have Every Reason to Get Involved

The Hackaday Prize truly has something for everyone. Making the world a better place doesn’t end with a grand prize for a single build. Just by talking about your ideas and sharing your excitement you become the inspiration for this and every successive generation of problem solvers. But yes, there are prizes — a lot of prizes — and they’re spectacular.

We have over $250,000 in cash going out to hundreds of entries this year. The Grand Prize of $50,000 is joined once again this year by the Best Product Prize of $30,000. Four other entries will place second through fifth and receive $20k, $15k, $10k, and $5k respectively.

But the breadth of entries is too great to stop at that. We’ll select 120 projects as finalists and award each $1000. You can even get in on Seed Funding starting right away. We’re saving those details for the end of this announcement.

How Do I Build Something that Matters?

Whoa, all this talk of prizes, but you want to know what kind of hardware will be a hit for the Hackaday Prize? Here’s what you need to know: you can enter your project at any time from now until October 16th. But the exact time that you enter matters.

Your best bet is to get started right away. The first challenge of the Hackaday Prize is: Design Your Concept. Every great build starts with a plan and this is the time to show us what you got. The key is to consider if the project benefits society in some way. Show us how, document your build plan, and you can be one of the first twenty finalists to receive $1k cash and move on to compete for the big prizes.

We’ll have four more challenges that focus on different types of entries. You only need to enter one challenge, but you may choose to enter (and win) as many of the five challenges as you wish. We’ll be looking for ~~connected devices that don’t suck~~ Internet of Useful Things during the IuT ! IoT challenge. After that, it’s on to all things mobile with the Wheels, Wings, and Walkers challenge. Assistive Technology challenges you to make the world a better place for the physically or mentally challenged and aging or sick people of the world. And finally, a Hackaday favorite closes the challenge rounds with Anything Goes — as long as it clearly benefits society. Each of these five challenges will yield twenty finalists who receive $1000. That’s $100k!

The Return of Best Product

Two years ago we tried something new by adding the Best Product Prize to the mix and it was an enormous hit. We’re happy to be able to bring it back again this year.

There is a difficult path from a working prototype to a product ready for its audience. As hardware development is unlocked for an ever wider engineering community, we want to see the path made wider so that the journey becomes easier. Best Product is designed to do just that.

Any Hackaday Prize entry may also choose to compete and be named the Best Product (receiving much deserved recognition as well as the addition $30k prize). You need to submit your entry no later than July 24th, which includes full documentation of the project as well as a bill of materials used in the build. We’ll select twenty finalists (sending $1k to each) who will then need to deliver three working beta test units for the final judging round of the Best Product.

How Can We Pick the Top Entries?

One amazing part of the Hackaday Prize family are the world-renowned experts who donate their time and talent as Judges. They are just as eager as everyone else to see all of this creative energy focused on solving the problems facing our civilization.

Learn more about all of these amazing people on the Hackaday Prize page.

One Last Thing: Seed Funding

When realized to their full potential, design concepts should knock the socks off of anyone who reads through them. Because of this we have one more thing in store for you during the first challenge which starts right now.

Entries with the most likes at the end of the first round will split $4,000. Each time someone on Hackaday.io “likes” your project it will move a bit higher on the leaderboard found on the Hackaday Prize page. The top projects will receive $1 for each like, with a max of $200 per entry so that at least twenty will win (but likely many more).

This seed funding is a little push to help offset the cost of building prototypes. But it really comes down to your decision to make the time and to make a difference. Enter your project in the Hackaday Prize now.

Inside The Supplyframe Design Lab On Opening Night

June 28, 2016 by Mike Szczys 13 Comments

Last week the Supplyframe Design Lab in Pasadena opened it’s doors, welcoming in the community to explore the newly rebuilt interior which is now filled with high-end prototyping and fabrication tools and bristling with work areas to suit any need. I had a chance to pull a few people aside during the opening night party to talk about how the Design Lab came about and what we can expect coming out of the space in the near future.

Opening night was heavily attended. I recognized many faces, but the majority of those exploring the building were new acquaintances for me. This is likely due to a strong connection the Design Lab is building with the students, faculty, and graduates of the ArtCenter College of Design. Located just down the road, it is one of the top design schools in the world.

Retrotechtacular: The First Atlas Launch

September 30, 2014 by Kristina Panos 31 Comments

As the Cold War conflict expanded in the 1950s, the Soviet Union dry-tested a hydrogen bomb and defense tactics became a top priority for the United States. Seeking to create a long-range nuclear missile option, the Air Force contracted Convair Astronautics to deliver SM-65 Atlas, the first in series of ICBMs. In the spotlight this week is a sort of video progress report which shows the first launch from Cape Canaveral’s LC-14 on June 11, 1957.

After the angle of attack probe is unsheathed, everyone moves out of the way. The launch is being monitored by base central control, but the swingin’ spot to spectate is the blockhouse. They have a periscope and everything. As the countdown continues, liquid oxygen pipelines whistle and wail into the idyllic Florida afternoon with the urgency of a thousand teakettles. Cameras and tracking equipment are readied, and the blockhouse’s blast door is sealed up tight.

The Hackaday Store Lives Again!

September 10, 2014 by Mike Szczys 58 Comments

Once upon a time there was a store where you could find the most amazing Hackaday shirts and other swag. If you managed to get one of the rare Jolly Wrencher adorned shirts back then, it’s probably about worn out by now. Prepare to rejoice, Hackaday has a completely new store packed with T-shirts, tools, and stuff to help you fill up those waking hours with hardware hacking goodness.

We’ve had a little fun over the last couple of days with posts that hint (maybe a bit too subtly?) that this was coming. We always try to have a little bit of fun for those of you who are really paying attention. Now we’re wondering who will be the first to implement the one-time pad as a dedicated piece of hardware… project ideas need to come from somewhere, right?

Take a look around the general store and you’ll see this time we have more than just stuff you wear. Hackers need tools and we’ve selected a small but inspiring group of must-have’s. The kits and toys we’ve selected are surely a rabbit hole of personal challenges and evolving hacks for you. And the best part is that these choices are one more way for us to promote the virtue of Open Design (it is the way). The only question now is what other open hardware do you want to see added to those ranks?
