Flashing Light Prize 2018: This Time with Neon

The Flashing Light Prize is back this year with a noble twist. And judging from the small set of entries thus far, this is going to be an interesting challenge.

Last year’s Flashing Light Prize was an informal contest with a simple goal: flash an incandescent lamp in the most interesting way possible. This year’s rules are essentially the same as last year, specifying mainly that the bulb itself has to light up — no mechanical shutters — and that it has to flash at 1 Hz with a 50% duty cycle for at least five minutes. But where last year’s contest specified incandescent lamps, this year you’ve got to find a way to flash something with neon in it. It could be an off-the-shelf neon pilot light, a recycled neon sign, or even the beloved Nixie tube. But we suspect that points will be awarded for extreme creativity, so it pays to push the envelope. Last year’s winner used a Wimhurst machine to supply the secondary of an ignition coil and flash a pair of bulbs connected across the primary, so the more Rube Goldberg-esque, the better your chances.

There are only a handful of entries right now, with our favorite being [Ben Krasnow]’s mashup of electricity, mechanics, chemistry, and physics. You’ve got until March 15th to post your flashing neon creation, and there are two categories this year, each with a £200 prize. Get your flash on and win this one for Hackaday.

Win Big Prizes With Repairs You Can Print

Another month, another contest, and this time we’re looking for the best 3D printed repairs you’ve built.

The Repairs You Can Print Contest on Hackaday.io is a challenge to show off the real reason you bought a 3D printer. We want to see replacement parts, improved functionality, or a tool or jig that made a tough repair a snap. Think of this as the opposite of printing low poly Pokemon or Fallout armor. This is a contest to demonstrate the most utilitarian uses of a 3D printer. Whether you fixed your refrigerator, luggage, jet engine, vacuum cleaner, bike headlight, or anything else, we want to see how you did it!

The top twenty projects in the Repairs You Can Print contest will be rewarded with $100 in Tindie credit. That’s a Benjamin to spend on parts, upgrades, and components to take your next project to the next level!

Students and Organizations Can Win Big

The Best Student and Best Organization will win a Prusa i3 MK3!

This contest is open to everyone, but we’re also looking for the best projects to come from students and hackerspaces. We’ll be giving away two amazing 3D printers to the best Student entry and best Organization entry. These two top projects will be awarded an Original Prusa i3 MK3 with the Quad Material upgrade kit. This is one of the finest 3D printers you can buy right now, and we’re giving these away to the best student, hackerspaces, robotics club, or tool lending library.

If you have a project in mind, head on over to Hackaday.io and create a project demonstrating your 3D printed repair!

What is This Contest All About?

This contest is all about Repairs You Can Print, but what does that actually mean? Instead of printing Pokemon or plastic baubles on your desktop CNC machine, we’re looking for replacement parts. We’re looking for commercial, off the shelf items that were broken, but repaired with the help of a 3D printer. Is your repair good enough to show off as part of the contest? Yes! That’s the point, we want to see the clever repair jobs that people often don’t spend much time talking about because they just work.

Need some examples? Sure thing.

A while back, [Elliot Williams], one of the fantastic Hackaday Editors, had a broken vacuum cleaner. The wheels were crap, but luckily they were designed as a single part that snaps into a swivel socket. Over six or so years, the original wheels in this vacuum gave out, but a replacement part was quickly printed and stuffed into the socket. The new wheels have been going strong for a year now. That’s an entire year of use for a vacuum for five cents worth of plastic and an hour’s worth of printing time.

Need another example? My suitcase was apparently dragged behind a luggage cart for miles at either ORD or PHL. When it arrived on the baggage carousel, one wheel was shredded, and the wheel mount was ground down to almost the axle. The rest of the bag was still good, and I just removed the old wheel, salvaged the bearings, and printed a new wheel out of PLA. This suitcase has now traveled 60,000 miles with a 3D printed wheel, and it’s only now looking worse for wear.

How To Get In On The Action

We’re looking for the best repairs, jigs, and tools you’ve ever printed. To get started, head on over to Hackaday.io, create a new project, and document your repair. The Repairs You Can Print contest will run from Tuesday, January 16th, 2018 through 12 PM PST Tuesday, February 20th, 2018. Here’s a handy count down timer for ‘ya.

Coin Cell Challenge: Use Coin Cell, Win Prizes

Today, we’re calling all hackers to do the most with a single coin cell. It’s the Coin Cell Challenge, and we’re looking for everything from the most low-power electronics to a supernova in a button cell battery.

Electronics are sucking down fewer and fewer amps every year. Low power is the future, and we’re wondering how far we can push the capabilities of those tiny discs full of power. The Coin Cell Challenge is your chance to plumb the depths of what can be done with the humble coin cell.

This is a contest, and as with the tradition of the Open 7400 Logic Competition and the recent Flashing Light Prize, we want to see what the community can come up with. The idea is simple: do something cool with a single coin cell and you’ll secure your fifteen minutes of fame and win a prize.

Three Challenges

To kick this contest off, we’re opening up three challenges to all contenders to the world heavyweight champion of button cell exploits. The first, the Lifetime Award, will go to whoever can run something interesting the longest amount of time on a coin cell. The Supernova Award is the opposite – what is the most exciting thing you can do with a button cell battery, lifetime be damned? The Heavy Lifting Award will go to the project that is the most unbelievable. If you think you can’t do that with a coin cell battery — lifting a piano or starting a car, for example — odds are you probably can. We want to see it.

Prizes and Rules

All Hackaday hardware hacking challenges need prizes, and for this one, we’re rolling out the red carpet. We’re offering up cash prizes for the top coin cell hacks. There are three $500 USD cash prizes, one for each winner of the Lifetime, Supernova, and Heavy Lifting awards. We’re not stopping there, because the top twenty builds overall will each receive $100 in Tindie credit, where the winners can cash in on some artisanal electronics sold by the people who design them.

What do you have to do to get in on this action? First, you need to build something. This something must be powered by nothing more than a single coin cell battery and must include some type of electronics. We also want this to be Open Source, and you’ll need to start a project on hackaday.io. The full rules are available over here, but don’t wait — the deadline for entry is January 8th, 2018.

We’re excited to see what the community comes up with, and who will find a production coin cell that’s the size of a dinner plate. This is going to be a great contest with overheating coin cells and tiny bits of metal flying across the room. This is going to be a contest filled with blinkies and wireless devices that run for far, far too long. Someone is going to misread the rules and tape together a meter tall pile of coin cells. It’s going to be awesome, so start your project now.

Hackaday Links: December 25th, 2016

You should be watching the Doctor Who Christmas special right now. Does anyone know when the Resturant at the End of the Universe spinoff is airing?

We have a contest going on right now. It’s the 1 kB Challenge, a contest that challenges you to do the most with a kilobyte of machine code. The deadline is January 5th, so get cracking.

A few years ago, [Kwabena] created the OpenMV, a Python-powered machine vision module that doesn’t require a separate computer. It’s awesome, and we’re going to have his talk from the Hackaday SuperConference up shortly. Now the OpenMV is getting an upgrade. The upgrades include an ARM Cortex M7, more RAM, more heap for less money. Here’s a link to preorder.

There ain’t no demoscene party like an Amtrak demoscene party because an Amtrak demoscene party lasts ten hours.

E-paper displays are fancy, cool, and low-power. Putting them in a project, however, is difficult. You need to acquire these display modules, and this has usually been a pain. Now Eink has a web shop where you can peruse and purchase epaper display modules and drivers.

[Kris] built a pair of STM32L4 dev boards that are easily programmed in the Arduino IDE. Now he’s putting these boards up on Kickstarter. The prices are reasonable – $15 for the smaller of the pair, and $25 for the bigger one. Remember, kids: ARM is the future, at least until RISC-V takes over.

This is how you do holiday greeting cards.

Didn’t get what you want for Christmas?  Don’t worry, Amazon still has A Million Random Digits with 100,000 Normal Deviates in stock. It’s also available on audible dot com. Sometimes we don’t have time to sit down and read a million random digits but with audible dot com, you can listen to a million random digits in audio book format. That’s audible dot com please give us money.

northkoreaThis is the last Hackaday Links post of the year, which means it’s time for one of our most cherished traditions: reviewing our readership in North Korea.

It’s been a banner year for Hackaday in the Democratic People’s Republic of North Korea. The readership has exploded in 2016, with a gain of nearly 300%. To put that in perspective, in 2015 we had thirty-six views from North Korea across every page on Hackaday. In 2016, that number increased to one hundred and forty.

That’s a phenomenal increase and a yearly growth that is unheard of in the publishing industry. We’d like to tip our hat to all our North Korean reader, and we’re looking forward to serving you in 2017.

The Square Inch Project

For the last few years, Hackaday has been putting together some amazing contests. We gave away a trip to space, but the winner took the money instead. We gave away another trip to space, but those winners took the money instead. But we had a ton of fun along the way and are glad to see some others are getting in on the action. In September, a contest appeared out of the blue on hackaday.io. It is the Square Inch Project, a contest with the goal of stuffing the most electronics on a square inch of printed circuit board.

This wasn’t a contest designed, planned, or organized by anyone in charge here; this is a completely organic competition arranged and implemented by the hackaday.io community. A few months ago, a few notable hackaday.io people just decided to have a contest. Awesome.

OSHPark was kind enough to give out credits for PCBs as prizes, a we added in a few gift certificates to the Hackaday Store. Apparently that’s all you need to get a lot of people making a lot of cool stuff.

There are a lot of really great entries – far too many to cover in a single post – but you’ll find a few great ones below.

Caption CERN Contest — Prize Upgrade this Week

Week 13 of the Caption CERN Contest might be gone, but our intrepid scientist is still rocking his caffeine rush. Thanks for the captions! We’re still trying to figure out if the faces in on the wall are anyone famous – and who exactly are in the cartoon postcards toward the top of the wall. A few readers picked up on what looks to be a compressed air hose in the background. Every office has their coffee station, but we’re betting this particular CERN lab had some seriously frothy milk!

The Funnies:

  • “Schroedinger’s fist-bump” – [Jarrett]
  • “Even though the other scientists had rejected John’s idea to control the accelerator with a six speed manual transmission, he would often close his eyes and imagine shifting through the gears of a machine with a few trillion electron volts under the hood.”- [MechaTweak]
  • “At CERN the coffee doesn’t have a lot of kick, but it does have some punch..” – [THX1082]

The winner for this week is [Matt] with ‘”this is going to make one gooood coffee rush selfie. All my friends are doing it. We post them on the wall.” – CERN staff really were ahead of their time.’ [Matt] won a sweet Robot Head T-Shirt From The Hackaday Store!

Week 14: Prize Upgrade!

cern-14-smWe’ve seen a lot of strange equipment here at Hackaday, but Week 14’s image left us at a loss for words, at least for a few minutes. What the heck is this thing? Pressure vessel? RF chamber? Looking at this image and another one depicting a strange device in CERN’s labs, we haven’t the foggiest idea. We do know it’s large, and these two CERN scientists are working hard to get it ready for… something. It also has fins. Fins make everything cooler. Beyond that – we’re leaving this one in the capable hands of our caption team on Hackaday.io.

buspirate2We’re sweetening the pot a bit this week. Up until now, our weekly prize has been a T-shirt. While clothing is important, we know that hackers love hacking tools, so this week’s prize will be a Bus Pirate from The Hackaday store. We’ll try to change it up each week with a different device.

Add your humorous caption as a comment to this project log. Make sure you’re commenting on the contest log, not on the contest itself. As always, if you actually have information about the image or the people in it, let CERN know on the original image discussion page.

Good Luck!

Caption CERN Contest Week 13

Week 12 of the Caption CERN Contest and the strange stringed scientific instrument it brought along are both history. As always, thank you for your captions! They provided quite a few chuckles in the busy week gearing up for our Hackathon. We’re still not sure exactly what is being built here – Our best guess is it’s some sort of detector for emissions. But what sort of emissions? Was CERN looking for electric fields, magnetic fields, or something else entirely? It’s interesting to note that just as the photographer’s flash reflected in all 5 layers of wire, an RF signal would bounce off the rear reflector and strike the wires.

The Funnies:

  • “Ooh, it’s so beautiful, is this a harp?”
    “Close, it is for HAARP” – [Federico Churca-Torrusio]
  • “Bones was right this thing will scatter your molecules across space.”- [scott galvin]
  • “Eight years of schooling and two post doctoral fellowships just so I can make quilts. I should have been a dentist.” – [Narfnezzle Nickerbots]

The winner for this week is [THX1082] with “CERN’s early attempts at developing “String theory”. They’re doing it wrong. [THX1082] will be at his next hackerspace meeting wearing a CRT Android T-Shirt From The Hackaday Store!

Week 13: Coffee time at CERN!

cern-13-smEvery week we get at least one caption explaining that the strange piece of equipment included in that week’s image is a coffee maker. I thought it would only be right to include this shot of CERN’s real coffee nook, and a scientist about to enjoy a fresh cup of liquid “get ‘er done”. I have to thank CERN’s photographer for grabbing this slice of life shot!

It’s worth taking the time to check out the high res JPEG direct from CERN, as you can really zoom in on the post cards and photographs in the background. One even says “Tout va tres bien” – which Google translates to “Everything is going very well”. Some jokes never get old!

Add your humorous caption as a comment to this project log. Make sure you’re commenting on the contest log, not on the contest itself.

As always, if you actually have information about the image or the people in it, let CERN know on the original image discussion page.

Good Luck!
