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!

Caption CERN Contest Week 12

Week 11 of the Caption CERN Contest has flown by faster than the mullet or hammer pants. Thank you for all the wonderful captions. Some of our astute readers noticed that this week’s photo actually worked as cross view 3D image. This was unintentional, but a pretty cool bonus. The telephone in the background moved just enough to give the image some depth. We probably will never know what exactly these scientists were working on, and why they needed a PDP 11 with some custom hardware to run calculations. They definitely provided us with some entertaining captions though!

The Funnies:

  • “I know this PDP was expensive, but do we all REALLY need to take a photo with it? I have like serious science to do!” – [Matthew Hoskins]
  • “They all laughed at Jane when she said she was going to mine bitcoin with her 168 E. Now they fear the click of her Prada boots and Versace wardrobe. “- [mathew.stevens]
  • “Linda! We didn’t get a PDP-11 to play Zork!” – [el.Cannibal]

The winner for this week is [XLT_Frank] with “These ladies were essential to proper operation at CERN because unlike the men, they read the manuals”. As a reward for his efforts, [XLT_Frank] wins a CRT Android T-Shirt From The Hackaday Store!

On to week 12!

cern-12-smOne of the best parts of running the Caption CERN Contest is checking out the new images on CERN’s servers each week. Every week I find new images to zoom in on. I trace wires, look at equipment ID cards, and generally try to figure out what exactly is going on.

This image is no exception. At first glance, one would think the CERN photographer was trying out some multiple exposure techniques. Zooming in on the high res JPG available at the original CERN page shows that the strange phenomenon in the center of the image are actually layers of fine wire strung between the two sides of the curve. Between that and the 80’s clean room outfits, this must have been a very important piece of scientific equipment!

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!

Make Awesome, Win Smoothieboard

If you haven’t looked around the RepRap project in a while, you probably haven’t heard about the Smoothieboard. It’s an extremely unique electronics board for 3D printers, laser cutters, and CNC machines that is trying to get away from Atmel and AVR microcontrollers and towards more powerful ARM micros. On the Smoothieboard, you’ll find enough five motor drivers, six big ‘ol MOSFETs for hot ends, fans, and beds, enough thermistor inputs for just about anything, and an Ethernet jack, because all 3D printers should be able to run headless.

The team behind the Smoothieboard has decided there’s not enough awesome included in the Smoothieboard already. To fix this, they’re opening up a contest where coders, documentarians, graphic artists, and creatives of all types can contribute to the Smoothieboard project. What’s the prize? A Smoothieboard, duh.

The Smoothieboard team is looking for a few good coders, builders, or anyone else to contribute to the Smoothieboard project. If you have an idea that would work with the Smoothieboard – a web interface like Octoprint running on the Smoothieboard, better documentation, graphics, or just want to build a five-axis CNC mill, this is where you sign up. The prize is a Smoothieboard 5XC, the top of the line board with five motor drivers.

Of course you’re always welcome to not contribute to open source projects, and for those consummate consumers, we have the Smoothieboard 5XC available in the Hackaday Store.

You have until February 15th to come up with a great project idea for a Smoothieboard. The best 30 project ideas will be chosen, and those projects will get a Smoothieboard. Actually building a project in a month isn’t a condition of the contest; the best idea wins.

Wireless Bullduino belt buckle sets the stage for romance, schtick


As the Red Bull Creation Contest gets underway, we’re seeing a ton of great entries, including this one put together by [Team Instructables]. While we are pretty partial to our own spectacular Red Bull Cannon, it’s hard to deny that there is some stiff competition out there.

Instructables’ “Romance Pants” are a creation that would undoubtedly fit perfectly as a prop piece for any of the Naked Gun movies. The basic premise behind the pants is that when unzipped, the Bullduino belt buckle wirelessly signals the lights in the room to dim, the music to turn up, and candles to light – setting the mood for romance.

Some might argue that anyone wearing a Red Bull-themed Arduino as a belt buckle would have a snowball’s chance in hell of encountering a potential mate – We can’t really argue with you there. That said, their concept is pretty amusing.

Stick around to see the Romance Pants in action, as well as a behind the scenes look at how they work.

[Thanks, Bill!]
