CAPTION CERN CONTEST – Accidents Happen

May 14, 2015 by Adam Fabio 29 Comments

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

Accidents 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.

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!

Direction Projection Is A Beacon In The Night

May 13, 2015 by Adam Fabio 35 Comments

Navigating with your phone can be a hassle: the phone displays a tiny map that you’re never supposed to look at while driving, but of course you do. [Mikeasaurus] has the ultimate solution: Direction Projection! Mike has created an augmented reality system with no glass heads-up display, and no goggles ala Microsoft Hololens. The road ahead is his canvas. A standard projector mounted atop his car displays maps and turn indicators, all from his phone. Linking the phone and projection system would normally involve HDMI or analog video cables strung through the roof. [Mikeasaurus] simplifies that by using a Chromecast, which allows him to stream his phone’s screen over WiFi.

The projector itself is the HD25-LV, a 3500 Lumen model from Optima. the HD25-LV is capable of 1080p, though in this situation, brightness is much more important than resolution. [Mikeasaurus] mounted the projector along with a gel cell battery and 900 watt DC to AC inverter to power it. A mobile WiFi hotspot fills out the rooftop kit. Leaving an expensive setup like that on top of a car is a recipe for disaster – be it from rain, rocks, or theft. [Mikeasaurus] thought ahead and strapped his setup down inside a roof mounted cargo box. A plastic covered hole in the front of the box allows the projector to shoot down on the road while protecting its lens. We’d want to add a vent and fan to ensure that projector gets a bit of airflow as well.

On the road, the system actually works. Understandably, it’s not going to work very well during the day, but at night the system really shines! Just don’t tailgate – you wouldn’t want the driver in front of you to know exactly where you’re going, would you?

Field Trip! Hackaday Visits Adafruit Industries

May 8, 2015 by Adam Fabio 49 Comments

While still weary from our TechCrunch Disrupt Hackathon, The Hackaday crew had a chance we couldn’t pass up: A tour of Adafruit Industries. Adafruit isn’t open to the public, so an opportunity to see the inner workings of one of the largest companies in the hacker/maker industry was really something special.

Coming in off the hustle and bustle of lower Manhattan streets, we found ourselves in a nondescript white marble lobby. The contrast and colors made me think of a scene out of THX1138. A short elevator ride opens to a second lobby area with a large door. We weren’t alone though – a security camera stands silent witness. Any thoughts of Big Brother were quelled when the door was thrown open by none other than [Phil Torrone], welcoming us to Adafruit.

If you’ve seen any of the photos or videos of Adafruit’s offices, you know what to expect – a large, open space broken by the columns keeping the building’s 10 stories upright. It’s the perfect blank canvas upon which to build a company. Since we were there late on a Sunday afternoon, things were relatively quiet. Only a handful of the 80 Adafruit employees were at their stations. Those on hand were packing and scanning in orders, in preparation for what would be a busy Monday. It’s a bit hard to be standing in Adafruit, knowing that you’re within arm’s reach of every part, module, or device you’ve ever wanted, and not want to jump right in on a project. With 10 of us there that may have made a bit of a dent in Adafruit’s bottom line, though.

[Phil] shows off Adafruit’s Fona module

The Circuit Playground characters

The tour started at [Phil’s] desk. Tucked in among a copy of Dune, a very respectable graphic novel collection, and the two most recent editions of The Art of Electronics was United States Export Controls, 7th Edition. Considering the amount of shipping to far-flung countries the company has to do each day, one must stay on top of little things like ITAR and other export laws.

Throughout the tour, [Phil] made it clear that he views his job as a simple one: Do everything possible to allow [Limor] to crank out designs. [Phil] keeps the business running so she can keep on engineering open source hardware. [Phil’s] touches shine through though, in the product logos, and the characters which appear in Adafriut’s Circuit Playground. If those videos strike you as kid stuff, that’s exactly what they are designed to be. During his tenure at Make, [Phil] was one of four people who ran the first Makerfaire in 2006. He still gets e-mails from people who attended it as kids and were inspired to enter the fields of engineering or computer science. Both [Phil] and [Limor] have their sights set on inspiring the next generation of hackers.

Next up on our tour was the wearables department, domain of the one and only Becky Stern. We were all struck by how incredibly neat and organized the area was. There was a well-labelled place for everything, and everything was in its place. On display was a grey hoodie with a bandolier of ninjaflex 3D printed bullets, all lit by RGB LEDs.

Click past the break for the rest of Hackaday’s Tour of Adafruit Industries!

Hacklet 46 – ODROID Projects

May 8, 2015 by Adam Fabio 11 Comments

It seems you can’t mention the Raspberry Pi these days without someone bringing up the Odroid. Named after the combination of Open and Android, the current Odroid brand covers several boards – the U3, the UX3 with its 2 Ghz Samsung quad-core processor, and the C1, which is directly aimed at our favorite fruit pie computer. With all this popularity, one would expect a few awesome projects based around the Odroid machines, and you’d be right! This week’s Hacklet is all about projects using the Odroid on Hackaday.io!

We start with [herrkami] and CRONUS. Cronus started life as a Robbie Junior, Radio Shack’s re-branded version of Takara Tomy’s Omnibot Jr. [herrkami] has upgraded Cronus’ brain with an Odroid U3. Cronus can now reliably respond to voice commands thanks to a little help from Google’s speech recognition engine and the accompanying Python API. Cronus is rather conversational as well, all due to the AIML framework. [herrkami] hopes to cut the cord (or WiFi link) once he gets CMU sphinx up and running. Some of [herrkami’s] best work is in his cardboard templates to create a mechanism for turning Cronus’ head. These are some pretty sweet updates for a 1986 vintage robot!

Next up is [tlankford01] with Linux Tutorial: Odroid U3 Server w/ Seafile Cloud. [tlankford01] walks us through setting up a file server using the Odroid, a 16 Gigabyte EMMC card, and a hard drive to hold the files. As one might expect, this tutorial covers a LAMP (Linux, Apache, MySQL, PHP) server stack. The 9 project logs take us from a bare microSD card to a full server. The Odroid’s 2 Gigabytes of ram are put to good use running the open source Seafile cloud server package. Tutorials like this deserve lots of love from the Hackaday.io community. Sometimes you just need to get a solid file server up and running. When that happens, this type of project is often just what the doctor ordered! So don’t be a lurker, head over to [tlankford01]’s page and give him a skull!

[Victor] gets us one step closer to an Odroid tablet with the HDMI touchscreen. HDMI touchscreen is a project to connect a 7″ 1024 x 600 LCD with a capacitive touchscreen to HDMI based computers. The heart of the project is Texas Instrument’s TFP401 panelbus DVI receiver chip. This chip makes interfacing LCD screens to HDMI or DVI video cards (almost) painless. There still is a bit of X configuration to do to get things running. [Victor] even got his Odroid running in Android with his custom screen setup. Those of us who have spent time in display an input configuration file limbo know that this is no small feat!

Finally we have [darth_llamah] with Odroid-U3 HTPC. [Darth] raided his junkbox and parts drawers to build a solid home theater PC using the Odroid-U2. The U2 is a bit older than the current U3 models, but all [Darth’s] work should apply to any of the Odroid series. An old Itona case provided the frame for this hack, but it took a lot of custom work with plastic and epoxy to make everything fit. [Darth’s] software stack is the popular OpenELEC Linux build. [Darth] even setup a real “soft” power button using an ATtiny85 connected to USB and s Adafruit’s TrinketHidCombo library.

If you want to see all the Odroid projects in one place, check out our new Odroid projects list!

That’s it for this Hacklet, As always, see you next week. Same hack time, same hack channel, bringing you the best of Hackaday.io!

Caption CERN Contest — Prize Upgrade This Week

May 8, 2015 by Adam Fabio 8 Comments

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!

We’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.

We’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!

Hacklet 45 – Reverse Engineering Projects

May 1, 2015 by Adam Fabio 18 Comments

Sooner or later, all of us end up putting on our reverse engineering hats and digging in to a device. It might be that you’re trying to keep an old piece of equipment running – the manufacturer is long defunct, and parts are no longer available. It might be that sweet new router with locked down firmware. Or, it might just be that you’re curious. Whatever the reason, reverse engineering is a rewarding endeavor. Some of our favorite reverse engineering projects read like spy novels. Instead of cloak and dagger, it’s encryption and soldering iron. This week’s Hacklet focuses on some of the best reverse engineering projects on Hackday.io!

We start with [Henryk Plötz] and Reverse-Engineering a low-cost USB CO₂ monitor. Carbon monoxide detection and measurement devices are household safety items these days, and have become rather cheap. Carbon dioxide measuring devices are less common, and as expected, more expensive. [Henryk] found a device for around 80€ which did what he needed. The included USB connector was supposedly just for power, but when plugging it in, the device enumerated on his Linux box. The accompanying windows software displayed live data from the detector, but there wasn’t much information on the protocol. Time to bust out Ida pro, and go to town on that software! [Henryk] did battle with his CO₂ monitor”s software and was justly rewarded.

Next up is [Bob Blake] and Reverse Engineering the Maverick ET-732. [Bob] loves barbecue, but hates to babysit his smoker. Thankfully there are wireless temperature sensors out there built just for that purpose, but they have limited range and you can’t have multiple receivers around the house. [Bob] aimed to fix all of that by sending his Maverick wireless thermometer data to the web, so he could check in on his cooking from anywhere. First he had to reverse engineer the protocol used by the sensor. A spectrum analyzer told [Bob] that the sensor transmit frequency was 433.92 MHz, which is common for low-cost transmitters like this. [Bob] actually had some compatible receivers at his office, so he was quickly able to capture some data with his Saleae logic analyzer. The real fun came in figuring out exactly how the data was organized!

A chance Ebay sale netted [Technics] a sweet head mounted magnifier, but no way to control it. Reverse engineering a Life Optics M5 documents [Technics] efforts to get his new headgear working. The Life Optics M5 is actually a re-branded version of the Leica HM500 head mounted zoom microscope. These devices were originally designed for medical use. They provide a stereo view to the surgeon or dentist using them, as well as sending a video feed to be displayed for the rest of the team to use or record. Cracking open the M5’s head-mounted box revealed several modules, but no obvious means of controlling zoom or focus. Scoping out a few of the mystery wires did reveal what looks to be a 9600 baud serial data stream though. This is a brand new project, and we’re waiting for [Technics] next update to see if he gets to do some soldering with his new toy!

BIOS password protection – it’s the bane of any used laptop buyer’s existence. Sometimes removing these passwords are as easy as popping out the CMOS battery, other times, not so much. [q3k] found themselves in the latter situation with a bundle of Toshiba R100 laptops. and no way to start them up. [q3k] didn’t give up though – they broke out the soldering iron and started Reverse engineering Toshiba R100 BIOS. The R100 is a Pentium M era machine – old but still usable for many hacking purposes. Dumping the ROM BIOS of the laptop didn’t yield the information [q3k] needed, so they moved on to the TLCS-870 controller, and built a really nice board with a Xilinx Spartan6 FPGA to help with the effort. It turns out that the 870 is just used for power management. – [q3k] has now turned their attention to a Renesas microcontroller which might be just the droid they are looking for!

We think that reverse engineering projects are pretty darn cool, so we’ve created a Reverse Engineering List to keep them all organized.

That’s it for this Hacklet, As always, see you next week. Same hack time, same hack channel, bringing you the best of Hackaday.io!

Caption CERN Contest Week 13

April 30, 2015 by Adam Fabio 9 Comments

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!

Every 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!
