Caption CERN Contest – Not your father’s POV Display

Accidents happen – but the awesome quotes you all sent in for Week 15 of the Caption CERN Contest were no accident. A huge thank you for our biggest week yet! The scientists in this week’s image are definitely cleaning up after some type of nasty accident. At first blush it looks like an electrical problem in the coils of what appears to be part of a beam line. With all that soot and radiation dangers to boot, only the photographer and the people in the image know for sure!

The Funnies:

  • “This is the second server these idiots have fried! What the hell’s a Hulu, and why are they trying to watch Gilligan’s Island with it?” Thanks to some unplanned quantum tunneling, Berners-Lee was even further ahead of his time than he thought” – [The Green Gentleman] (Two weeks in a row!)
  • “I found the bug. Who gets to tell Joe he’s sterile?”- [jonsmirl]
  • “‘I told the Captain that she couldn’t take any more’ – Scotty” – [md_reeves]

The winner for this week is [Mr. mmWave] himself, [Tony Long] with “Hardware Accelerator moto – Fail Fast, Fail Often. Also applies to Accelerator Hardware.” [Tony] will be debugging his next microwave mm band ham radio with a Logic Pirate From The Hackaday Store! Congratulations [Tony]!

Week 16: This is not your father’s POV Display!

cern-16-smScientists at CERN have come up with some amazing science advancements. They’ve also needed ways to display the data they collect. This image may depict some incredible new way to display data collected from a high power physics experiment – or it could be a scientist’s project for the CERN science fair. We may never know.

The album is titled CHAMBRE A ETINCELLES DANS EXPO TECHNOL, which roughly translates to “Sparks in the technology expo room”. The lines traveling between the three horizontal display devices definitely appear to be aligned. Are they sparks of electricity? You tell us!

buspirate2Last week’s prize was a Logic Pirate. This week we’re giving away a Bus Pirate from The Hackaday Store.

CAPTION CERN CONTEST – Accidents Happen

Week 14’s image may have had us at a loss for words, but it definitely didn’t slow down the intrepid caption contest entrants on Hackaday.io! Thanks to everyone who entered. We still have no idea what that device is, though we are sure that we wouldn’t want to be standing under it. Just look at those 4×4 sections of lumber holding everything up. What’s the French translation for “sketchy as hell”? The device definitely includes a pressure or vacuum vessel of some sort. Beyond that, your guess is as good as ours. We’ll keep an eye on CERN’s image discussion page in case an answer does pop up.

The Funnies:

  • “Damn it Athol, stop harping about protocol and hand me the duck tape. This is nuclear physics, not rocket science!” – [The Green Gentleman]
  • “This will mix a mean Margarita for the party tomorrow, I promise you!.”- [Mats L]
  • “To long have we tried to smash particles, now we will blend them.” – [paul]

The winner for this week is [LongHairedHacker] with: “After weeks of complicated assembly the team finally found out that the IKEA Årc, was in fact not a fusion reactor. It did make a hell of an espresso though.”

As promised, [LongHairedHacker] will be taking home a Bus Pirate From The Hackaday Store!Congratulations!

Week 15

cern-15-smAccidents happen! When you’re working on the bleeding edge of science and technology, things don’t always go as planned. In this image, we’re looking at what appears to be the result of some sort of failure. We’re not sure what the piece of equipment was, but “was” is the proper term – as it’s now charred to a crisp.

The two scientists investigating the damage don’t seem to be worried about the radiation warning posted on the end of the machine’s aperture. Hopefully they know what they’re doing! 

Last week’s prize was a Bus Pirate. This week we’re giving away another Dangerous Prototypes design, a Logic Pirate from The Hackaday Store.

SNES Controller Modified to be Completely Wireless

[Pat] was looking for a way to wirelessly control his Fire TV unit. He could have just went with one of many possible consumer products, but he decided to take it a step further. He modified a unit to fit inside of an original SNES controller. All of the buttons are functional, and the controller even features a wireless charger.

[Pat] started out with a Bluetooth video game controller marketed more playing video games on tablets. The original controller looked sort of like an XBox controller in shape. [Pat] tore this controller open and managed to stuff the guts into an original SNES controller. He didn’t even have to remove the original SNES PCB. [Pat] mentions that it was rather tedious to rewire all of the buttons from the original controller, but in the end it wasn’t too difficult. The only externally visible modification to the original controller is a small hole that was made for a power button.

In order to make this unit completely wireless, [Pat] also installed a Qi wireless charging module. Now, placing the controller on a charging pad will charge up the small LiPo battery in just about 45 minutes. This controller would be the perfect addition to a RetroPi or other similar project. If you’re not into Bluetooth, you can try using a Logitech receiver instead. Continue reading “SNES Controller Modified to be Completely Wireless”

Amazon Fire TV Update Bricks Hacked Devices

The Amazon Fire TV is Amazon’s answer to all of the other streaming media devices on the market today. Amazon is reportedly selling these devices at cost, making very little off of the hardware sales. Instead, they are relying on the fact that most users will rent or purchase digital content on these boxes, and they can make more money in the long run this way. In fact, the device does not allow users to download content directly from the Google Play store, or even play media via USB disk. This makes it more likely that you will purchase content though Amazon’s own channels.

We’re hackers. We like to make things do what they were never intended to do. We like to add functionality. We want to customize, upgrade, and break our devices. It’s fun for us. It’s no surprise that hackers have been jail breaking these devices to see what else they are capable of. A side effect of these hacks is that content can be downloaded directly from Google Play. USB playback can also be enabled. This makes the device more useful to the consumer, but obviously is not in line with Amazon’s business strategy.

Amazon’s response to these hacks was to release a firmware update that will brick the device if it discovers that it has been rooted. It also will not allow a hacker to downgrade the firmware to an older version, since this would of course remove the root detection features.

This probably doesn’t come as a surprise to most of us. We’ve seen this type of thing for years with mobile phones. The iPhone has been locked to the Apple Store since the first generation, but the first iPhone was jailbroken just days after its initial release. Then there was the PlayStation 3 “downgrade” fiasco that resulted in hacks to restore the functionality. It seems that hackers and corporations are forever destined to disagree on who actually owns the hardware and what ownership really means. We’re locked in an epic game of cat and mouse, but usually the hackers seem to triumph in the end.

This Message will Self Destruct… as You Read It?

A group of Harvard chemists have come up with a novel use for fire. Through experimentation, they have been able to build what they call an InfoFuse. As the name implies, it’s essentially a burning fuse that can “transmit” information.

The fuse is made from flash paper, which is paper made from nitrocellulose. Flash paper burns at a relatively constant speed and leaves no smoke or ash, making it ideal for this type of project. The chemists developed a method of conveying information by changing the color of the flame on the paper. You might remember from high school chemistry class that you can change the color of fire by burning different metal salts. For example, burning copper can result in a blue flame. This is the key to the system.

The researchers dotted the flash paper with small bits of metal salts. As the flame reaches these spots, it briefly changes colors. They had to invent an algorithm to convert different color patterns to letters and numbers. It’s sort of like an ASCII table for fire. Their system uses only three colors. The three colors represent eight possible combinations of color at any given time. Just two quick pulses allow the researchers to convey all 26 letters of the English alphabet as well as ten digits and four symbols. In one test, the researchers were able to transmit a 20 character message in less than 4 seconds.

[Ben Krasnow] found the Harvard project and just had to try it out for himself. Rather than use colors to convey information, he took a more simple approach. He started with a basic strip of flash paper, but left large tabs periodically along its length. As the paper burns from end to end, it periodically hits one of these tabs and the flame gets bigger momentarily.

[Ben] uses an optical sensor and an oscilloscope to detect the quantity of light. The scope clearly shows the timing of each pulse of light, making it possible to very slowly convey information via fire. Ben goes further to speculate that it might be possible to build a “fire computer” using a similar method. Perhaps using multiple strips of paper, one can do some basic computational functions and represent the result in fire pulses. He’s looking for ideas, so if you have any be sure to send them his way! Also, be sure to check out Ben’s demonstration video below. Continue reading “This Message will Self Destruct… as You Read It?”

Add CNC to your…Propane Tank??!?

It’s starting to be that time of year again; the Halloween-themed hacks are rolling in.

[John Lauer] needed a propane-powered flame effect for his backyard ICBM “crash site”. Rather than pony up for an expensive, electronically-controlled propane
valve, he made a custom bracket to connect a stepper motor to the propane burner’s existing valve.

With the stepper motor connected up, a TinyG stepper motor controller and [John’s] own graphical interface, ChiliPeppr, take care of the rest.

The hack is almost certainly a case of “everything looks like a nail when you have a hammer” but you have to admit that it works well and probably didn’t take [John] all that much time to whip up. Maybe everyone should have a couple spare stepper motors with driver circuitry just lying around ready to go? You know, just in case.

All the details of the build are in the video. If you’re done watching the flames, skip to around 2:50 where we see the adapter in action and then [John] steps us through its construction.

You may have seen coverage of the TinyG motor controller here before.

Additional thanks to [Alden Hart] for the tip.

Hacklet #9 Bugs and Fire

9 This week on the Hacklet, we’re spending some time looking at bugs and fire! honeybeeFirst up we have [Noel] who is saving the bees with Bee-O-Neo-Tweet-O. Bees are incredibly important, both to Earth’s ecosystem and the food chain we humans need to survive. Unfortunately bees are also sensitive to some of the chemicals humans dump into the atmosphere. Sometimes it results in colored honey, but more often than not it’s detrimental to the bees.

Neonicotinoids are a class of insecticide that has been causing problems to hives near where they are used. [Noel] is banking on sensors created with bismuth electrodes to detect the chemical near the entrance to hives. The data can be collected by beekeepers all over the world and sent to a central server. He’s using an Arduino Yun as a WiFi connected base station. Each individual hive has an Adafriut Trinket and a 433MHz radio link to send data to the base. [Noel] is even hoping to detect individual bees by the sound of their wings beating.

hivemonitor

[Ken] is keeping his own bees, and wants to monitor more than just chemicals. His honeybee hive monitoring system keeps track of the temperature and weight (and thus the honey produced) by his hives. Rather than buy an expensive load cell setup, [Ken] modified a standard digital bathroom scale to suit his needs. The insects connect to the IOB (Internet of Bees) with a bit of help from the Apitronics platform and a BeagleBone Black. Ken even added a solar-powered weather station with the Apitronics system.

bug-killa[Mike] is taking a slightly different approach. He doesn’t want to save the bugs, he wants to kill the ones that bug him! [Mike] doesn’t want to get his hands dirty, so he’s created Lazy Killer 9000 for easy bug killing. Lazy Killer uses the business end of an electrified fly swatter to do its work. This project wouldn’t be complete without an Arduino, so [Mike] is adding one, as well as a WiFi shield. The entire system will have a friendly interface to turn the juice on. One of the best features of Lazy Killer is the internet connected kill count. [Mike] knows that there aren’t any bugs in the vacuum of space, so he’s entered Lazy Killer in The Hackaday Prize.

fire-charger

From bugs, we move on to Fire! [mr.jb.swe] needed a reliable portable power source. He found it in LiFePO4 batteries, but still needed a way to charge them. Toward that end he’s created The Multicharger, a watt meter and charger which can be powered from solar, wind, or thermometric power. A Powerpot X provides the fire and the power to charge the batteries. [mr.jb.swe’s] charger converts that into the standard constant current->constant voltage charging system needed by lithium chemistry batteries. The Multicharger isn’t a complete battery management system yet, but it’s well on its way.

Unitycandle candles have become a staple at wedding ceremonies.[Quinn] has taken things to the next level and beyond with this take on the classic unity candle. This candle throws fireballs 30 feet into the sky! We covered the candle back in June, but [Quinn] has been busy since then. With over 20 updates, [Quinn] has created one of the most well documented projects on Hackaday.io. Of course, being that this project is dealing with propane and monstrous fires, [Quinn] mentions you shouldn’t try unless you really know what you’re doing. Don’t set any brides on fire! That’s it for this week’s Hacklet! Tune in next week, same hack time, same hack channel, for more of the best of Hackaday.io!
