Diamond Thermal Paste: Update
Mike Szczys
[ "Misc Hacks" ]
[ "arctic silver", "ceramique", "diamonds", "dow", "heat sink", "thermal paste" ]
The need to conduct laboratory-style experiments runs deep in some people. [Freddyman] built an apparatus to test out several commercial and homemade thermal pastes , including the DIY diamond thermal grease we reported on last month . He setup each experiment in the middle of an air conditioned room, ran the heat sink fan for 30 minutes to equalize the temperature, then turned on the DIY heat generator that the paste and heat sink were connected to. He’s got a lot of data from tests he ran with the eight thermal conductors; air (using no paste), Arctic Silver 5 , Ceramique , Dow thermal fluid , pure silicone oil, silicone and diamond slurry, Dow fluid with diamonds, and the Inventgeek.com remake. One of the big problems with DIY paste is the air bubbles that are introduced into the slurry as you mix in the diamonds. All of the homemade pastes except one were put in a vacuum chamber in an attempt to remove tiny bubbles. The one that wasn’t put in the vacuum performed the worst of all the thermal conductors. In all cases, the commercially available products performed quite well while the DIY solutions delivered mixed results.

I know of only one truly scientific study that used the appropriate scientific equipment to determine actual results. Overclockers.com conclusively showed the power of diamond based cooling a year before the InventGeek article. InventGeek even reference it. The article has been ironically removed but is available on the way back machine. So before you go throwing the first stone remember your testing methods are equally flawed though well thought out. In the words of the original article by oc.com, “a specially designed and built calorimeter was used. This is a precise instrument that cost about $75,000 to build.”. Secondly I would never test with or use in construction for test equipment wood. It is a tremendous insulator and with each test you change the thermal characteristics of the material with repeated attaching and seating of your heat sink and smearing of thermal compounds absorbed by the wood. Finally you didn’t even test and compare the actual test they did using arctic silver, so you’re testing is far from conclusive.

DIY Coffee Table Scale
Jake W
[ "Misc Hacks" ]
[ "balance", "coffee table", "Guus", "scale", "weight" ]
[Guus] screwed together this coffee table which doubles as a scale . No welding was required to put it together – just some bolts, pulleys, miscellaneous fittings, and an original design. The weight is indicated through the (unlabeled) position of the counterweight arm. Currently it is limited to measuring 10kg (22 pounds), but can easily be boosted by adding a heavier counterweight. It looks pretty robust, maintenance-free, and fitting for any living room workshop’s weighing needs. [Guus] is also the proud inventor of the rock radio , and he is working on creating Man-Y-Man : a modular play system allowing children to create up to 1520 unique creatures.

Here’s a clue: the first thing you will need to do, whether you find it aesthetic or not, is print “not legal for trade” in some place where it is prominently visible when you are reading the “display.”You don’t get to not do this. It is very illegal almost everywhere to build a scale, much less to market it, without placing a prominent notice that it has not undergone the usual testing and calibration procedures.There is long-standing reason for this; it’s always been more profitable to build a cheating scale than to supply product at better cost. So modern industrial countries get a bit picky about the tech. The ancient egyptians deified scales (in person of the goddess ma’at) because of their role as revealer of hidden truths, but they can also be the teller of hard to reveal lies if misused.I won’t even get into all the things that would be wrong with this design if it were meant to perform more than a decorative function; the bearings in casters are not up to the job of substituting for pivots and bearings, nor are the rolling surfaces of casters dimensionally stable enough to be trusted in this function.Scales are very subtle; if they’re properly working they don’t move much and things can easily go wrong with them that aren’t immediately obvious, but cause their readings to become totally whacked.

Farewell, Hack A Day
Eliot
[ "News" ]
[ "@sweetums", "anniversary", "eliot", "eliot phillips", "robotskirts" ]
Now, on the eve of Hack a Day’s fifth anniversary, seems like an appropriate time to announce my resignation. Site founder [ Phillip Torrone ] published the first post, a red box , on September 5th, 2004. On May 7th, 2005 I took over editorial duties at Hack a Day by publishing one of my favorite projects: [Jonathan Westhues]’ proximity card spoofer . Since then, I’ve run Hack a Day with a number of great contributors over the last four years: [ Fabienne Serriere ], [ Will O’Brien ], [ Ian Lesnet ], and current senior editor [ Caleb Kraft ] just to name a few. I’ve enjoyed watching the site grow, powered by the constant stream of tips from readers . Whether we were turning hard drives into molten goo or putting our hardware designs into production, it’s been a lot of fun. With all the new talent we’ve brought on recently, I have confidence that Hack a Day will continue to be a great resource in the future. You’ll be able to find me online running my personal blog RobotSkirts.com and on Twitter as @sweetums . In real life, I’ll still be attending hacker conferences, like the upcoming ToorCon in San Diego , and local Los Angeles tech events like Mindshare and the weekly Hacker Drinkup . In closing, I’d like to thank you, the readers, for all the support you’ve given us over the years. If it weren’t for all the tips, personal projects, and ideas you’ve sent us, we’d never have made it this far. Thank you. [photo: Viss ]

Hard Core Nintendo DSI Hacking
Caleb Kraft
[ "Nintendo DS Hacks", "Nintendo Hacks" ]
[ "dsi", "microscope", "nintendo", "solder" ]
So, you hacked your DSI did you? Let me guess, you ran a flash cart . No? You probably added some LEDs then right? No? You must be pretty hard core, did you add a NES controler ? No? Well what did you do? We still have no idea what this guy is doing. But he is doing it very meticulously. We found [Micah Dowty]’s photo stream on flicker and we were instantly pulled in. He has done some extensive modifications to his DSI. He has spread its innards for all to see and begun hacking. It appears as though most of this is for memory dumps and direct access to the RAM in the unit, but frankly we just want to stare at these pictures.

How A Storage Company Builds Their Own
Mike Szczys
[ "Linux Hacks" ]
[ "debian", "hard drive", "hdd", "jfs", "raid", "storage" ]
Want 67 Terabytes of local storage? That’ll be $7,867 but only if you build it yourself. Blackblaze sells online storage, but when setting up their company they found the only economical way was to build their own storage pods. Lucky for us they followed the lead of other companies and decided to share how they built their own storage farm using some custom, some consumer, and some open source components. Each pod is a standalone HTTPS-connected storage unit with 45 hard drives in it. Nine SATA port expanders connect to 4 SATA controller cards on the mainboard. The system boots from a 46th hard drive into 64-bit debian . Drives are running RAID 6 and using the Journaled File System (JFS) . Our first thought when reading this was about the heat generated by those drives. A custom case houses all of this hardware and includes 6 big fans to take care of the cooling. [Thanks Dave]

The redundancy isn’t in the hardware (each red box is essentially designed to be throw away as I understand the solution). The beauty of this solution is in the software (which no one has access to, and they don’t really want to talk about – naturally, because that is their business edge) and how that software doesn’t require huge, complex redundant hardware systems.When you can build the hardware for next to nothing compared to commercial hardware storage solutions, who cares if you lose an entire rack of these boxes, because they were so cheap to build, they have 6 other copies of the data (made up number) in other racks and data centers. I’ve read some comments trashing speed, but when you realize that most people don’t have a fat enough pipe to strain these servers, that’s not an issue either.My assumption is that these boxes are seen as expensive 67TB hard drives in themselves.

Now, there are also solutions here (unlike a lot of comments here). Please, in the truest sense of research and commentary, provide feedback. If I’m chasing this down the wrong path, please let me know.So each of these nodes consist of 46 disks. One for the core operating system, and 45 disks provisioned in three 15 disk RAID 6 arrays. One obvious failure is the operating system disk, this would be very unlikely to lead to total data loss so we can rule that out.Additionally, lets analyze the problems in the perspective of a single 15 disk RAID 6 array. A failure in one does not mean anything is more likely to cause a failure in the other two, so let’s start there.They’re using 1.5 TB drives in their arrays, thus providing approx 19.5TB in each RAID 6 array. Important metrics to note:* These disks have a MTBF of 750,000 hours. (With 15 disks in the array, thats 15 disk hours for every geological hour)* The MTBF is for average use, not greater than average activityThe note about increased activity is important. When a drive fails, you will need to interleave reads across every single disk in order to recover parity information to rebuild the failed drive. Doing this while the drive is in use causes extra seeks across the head leading to an even higher than “normal” amount of activity, increasing chance of failure.More insidious is the chance for bit error issues.On a SATA disk, the error rate in bits is 1 in 10^14. Problem is, a single 1.5 TB disk provides 1.31941395 × 10^14 bits. If there is a problem with one of the disks, we will need to read 13 disks in order to produce the replacement data. This means, given the formula:Percentage_of_Loss = ( (Recovery_Disks * Disk_Capacity) / Error_Rate ) * 100And the values:Recovery Disks = 13Disk Capacity = 1.32 * 10^14 bitsError Rate = 10^14 bitsWe achieve a 1700% chance of inability to read a block of data. This means a guaranteed loss of data even at one tenth the probability.So, where to go from here? Well, first, we need a better filesystem. Filesystem Copy-on-write with checksumming alleviates these problems. On FreeBSD or Solaris, that would be ZFS. On Linux we’re looking at BTRFS or NILFS.A hardware RAID controller will do little to take care of this problem. While it can do checksumming of the disk and periodic health checks, it doesn’t change the fact that due to the size of disks now, ther WILL be errors. We need to move to a method of compensating for this by design.", "parent_id": null, "depth": 1, "replies": [] }, { "comment_id": "91872", "author": "redbeard", "timestamp": "2009-09-04T20:57:49", "content": "Apparently, it won’t let me post my bibliography, lets try it with broken links:Bibliography:hxtp://db.usenix.org/events/fast07/tech/schroeder/schroeder_html/index.htmlhxtp://research.google.com/archive/disk_failures.pdfhxtp://permabit.wordpress.com/2008/08/20/are-fibre-channel-and-scsi-drives-more-reliablehxtp://www.eweek.com/c/a/Data-Storage/Hard-Disk-MTBF-Flap-or-Farcehxtp://blog.econtech.selfip.org/2008/09/56-chance-your-hard-drive-is-not-fully-readable-a-lawsuit-in-the-making", "parent_id": null, "depth": 1, "replies": [] }, { "comment_id": "91887", "author": "M4CGYV3R", "timestamp": "2009-09-04T21:21:37", "content": "I’m totally making one.

Hackit: Why We Don’t Need Phone Numbers

[digg=http://digg.com/software/Why_we_don_t_need_phone_numbers]We’re starting to think that phone numbers are deprecated; it may be time to integrate how we connect telephones with the new digital millennium. To get a firm grasp on this topic it is important to take a look at the reason we started using phone numbers, why we still use them, and the why’s and how’s of transitioning to a new system. History of phone numbers Telephone numbers started out as a way of physically addressing a telephone extension. Whether connected by an operator at a switchboard or through a magnetic exchange, each number corresponded to the hardware switch that connected the handset you were trying to ring. This originally started with named exchanges such as Pennsylvania-6-5000. The geographic location of the extension was  shown in the name and this system gradually transitioned over to area codes and prefixes. Continued usage The proliferation of cell phones means that numbers are no longer tied to a physical location but are routed to the nearest tower to which each wireless phone is currently connected. So why have we continued to use telephone numbers? Backwards compatibility is paramount. Cell phones overtook land lines years ago but there are still millions of people connected to the telephone companies’ wired networks. Most of the phones used on these land lines rely on the touch tone system to function. Even the advent of Voice over Internet Protocol implements the same system of connecting calls by dialing a number. What works better than phone numbers? How many different phone numbers does your family have? Many households have a home phone, a cell phone for each family member, and a work phone for each adult. What if all of these numbers were addressed similarly to how the Domain Name System works for internet addresses? Something like this: phone://famiy.johndoe2155.voice/john_at_home phone://family.johndoe2155.voice/jane_at_home phone://www.your_company’s_domain.com/customer_service This can be accomplished in the near future. All cell phones and many land line phones already have the ability to store numbers so that you only have to enter them once. Cell phones can already input web-style addresses and a firmware upgrade would allow for a new system of addressing and storing voice connection information. Service providers like Comcast and Charter are already providing phone service that utilizes VOIP, paving the way for dialing from your computer. For legacy hardware an inexpensive interface box similar to the digital cable converter boxes could be implemented. The new box would have a keyboard and character LCD and be rolled out in the same way that caller ID boxes were. Conclusion No one wants to change their telephone number and be in the position of trying to inform everyone who might ever call them. This is why laws were enacted to allow you to keep your telephone number if you change carriers. If each family owned their “voice domain”, changing carriers, cities, or even countries would be as simple as editing the domain registration. Transitioning to a new system of dynamically addressed telephone extensions is the next logical step in voice communications. Although it would be a change for billions of people, it is possible and worth taking a look at. [photo credit Projekt Runeberg ]

Variable Range Sprinkler

[vimeo http://vimeo.com/6409575 w=470&h=352] [ Pete ], a musician , and the guy behind SparkFun’s pogobeds and locking footprints has a sprinkler hack. He wanted to keep his dog, Choppy, happy with a green lawn while also keeping his sidewalk water free. To solve this problem, he hacked his sprinkler and hose to adjust the sprinkler’s range. He uses an Arduino to read a potentiometer signifying the direction that the sprinkler is facing and a servo to adjust a hose valve that controls the sprinkler’s water flow. Be sure to check out the video above to see it in action.

[luis] added to the collection of MAME projects we’ve covered with his mini MAME cabinet build. This is his 5th mini cabinet and features a 5″ PlayStation LCD screen, a joystick, four control buttons, player 1 and 2 start buttons, speakers, and a lighted marquee. The controls are interfaced through an I-PAC and the system running the whole thing is a mini-ITX board with an Atom processor and two gigs of RAM. The build log is in Spanish and takes us all the way from a cardboard prototype to the finished particle board cabinet full of high quality artwork. Gameplay starts about 5:30 into the video.

[ "Misc Hacks" ]
[ "metronome", "PIC 16F", "tap" ]
[Adam] and his buddy [Matthew] sent in their tap-controlled metronome, or as they prefer, “ metronome with an attitude .” Using the piezo speaker you can tap patterns and rhythm into the memory and it will repeat it back to you in loop. The two buttons allow you to speed up or slow down the beat which is indicated by an led array. As per their request, we mention its entirely on a PIC 16F, not an Arduino. Perhaps the most interesting part we found that’s definitely worth checking out was their amazingly detailed build process . Check out a quick video of the metronome in action after the break.

Toyaanisqatsi: Time Lapse Control Using LEGO Parts

[youtube=http://www.youtube.com/watch?v=Fm1fFQfGc9M&feature=player_embedded] A simple panning motion can add impact to the already-dramatic effect of time lapse photography . To accomplish this, frugal cinematographers sometimes build [Rube Goldberg] contraptions from clock motors, VCR parts or telescope tracking mounts. Hack a Day reader [Stephan Martin] has assembled a clever bargain-basement system using an Arduino-driven stepper motor and a reduction gear system built up from LEGO Technic parts, along with some Processing code on a host PC to direct the show. While the photography is a bit crude (using just a webcam), [Stephan’s] underlying motion control setup might interest budding filmmakers with [Ron Fricke] aspirations but Top Ramen budgets. What’s more, unlike rigid clock motor approaches, software control of the camera mount has the potential for some interesting non-linear, fluid movements.

Take Command Of Your BASH Prompt
Mike Szczys
[ "Linux Hacks" ]
[ "bash", "linux", "prompt", "shell" ]
[Joshua] has put together a list of BASH prompt customizations . The command prompt is used in a command-line interface to show that the system is ready for the next command. Often times this is nothing more than a user name, host name, and working directory: mike@krusty:~$ [Joshua’s] customization examples can be used to color code the information in your prompt, change what information is displayed, and make the prompt respond differently when an invalid command is typed. A BASH prompt reference is helpful in deciphering what each of these commands do. The easiest simplification is to understand that non-printing characters (such as color codes) are surrounded in escaped square brackets. For example, line 1 is the sequence for Red, line 2 is the sequence for Dark Grey, and line 3 sets a simple prompt to display in Red and all text after that to be in Dark Grey: \[\e[0;31m\] \[\e[1;33m\] PS1="\[\e[0;31m\]\u@\h:\w\$ \[\e[1;30m\]" Above you will notice an added notification that we typed an invalid command. This prompt is produced with the following code: PS1="\`if [ \$? != 0 ]; then echo \[\e[33m\]---=== \[\e[31m\]Oh noes, bad command \[\e[33m\]===---; fi\`\n\[\e[1;30m\]XX \[\e[0;32m\]Hack a Day \[\e[1;30m\]XX\n\[\e[0;37m\][\[\e[1;31m\]\@\[\e[0;37m\]] \[\e[0;32m\]\u@\h \[\e[0;37m\][\[\e[1;34m\]\w\[\e[0;37m\]] \[\e[0;32m\]\$ \[\e[0m\] " We use the shell a lot and this transforms the prompt from something we mostly ignore into a useful tool. Typing a command in the shell will change the prompt for the current session only. If you want a more permanent change, add the line to the bottom of your ~/.bashrc file. [via Digg ]

Harry Potter Marauders Map Realized

[ "08m", "gps", "harry potter", "map", "marauders map", "PICAXE", "python", "swarm robotics", "wireless" ]
After reading about cheap wireless for microcontrollers , [Leigh] left a comment about his Marauders map . Much like the Harry Potter version, whoever holds the ‘map’ is able to see the location of the ‘marauders’ within certain bounds. Unlike the magical version however, each person being tracked needs to hold a PICAXE 08M, GPS, and 433.92MHz transmitter: while the map needs a computer running his Python script and a receiver of the same frequency. It has the potential for locating people, but we feel it might be better off in a swarm robotics setup.

Programmable Spring Actuator Legs
Caleb Kraft
[ "Robots Hacks" ]
[ "leash", "relex", "robot" ]
[youtube=http://www.youtube.com/watch?v=_g79mOSvSsE] This proof of concept shows an interesting way of making robotic legs. They are using programmable spring actuators to make these legs function as though they had a “reflex”.  The builder pulls the robot along on a leash. As the leg reaches its limit of backward motion, a signal is sent from the shoulder down to the knee that lifts it, causing it to return to the forward position. A signal is also sent to the opposing shoulder to suppress the lift reflex, keeping them from both stepping at the same time. The resulting motion is very organic feeling. We’re curious how this could be implemented in a robot which moves under its own power. [via makezine ]

Arduino Email Alert
Zach Banks
[ "Arduino Hacks", "Peripherals Hacks" ]
[ "alert", "arduino", "email", "ethernet", "notify", "pop", "pop3" ]
The Arduino makes a great platform for alert systems because it doesn’t need additional parts, other than an LED or motor . [Torchris] made email notifier , and used an Ethernet shield to make it standalone. The Arduino polls your POP server seeing if there are unread emails. POP is an incredibly simple protocol, even simpler than HTTP; this made it easy to communicate with, even with little processing power. He hopes to add a servo or serial display to present the data better, but his current system seems to work well. Video of it in action after the break.

Multi-screen Video With Ipod
Mike Szczys
[ "iphone hacks", "ipod hacks", "Video Hacks" ]
[ "iphone", "ipod touch", "MultiVid", "osc", "playback", "sync" ]
[ Marco Tempest] has developed some software called MultiVid that allows synchronized video across multiple iPhone or iPod Touch devices. For this to work, all of the devices must be connected to the same WiFi network. Playback can be controlled from any one of the iPhones/iPod Touches or from the Mac running the controller software. There is of course the option of connecting to larger monitors through a video output cable. The app also supports OSC. We’ve embedded the example video as well as a video detailing the software setup after the break. The client software is available at the apps store and controller software can be downloaded from [Marco’s] website . Both are free which is our favorite price point. [vimeo http://vimeo.com/6288279%5D Example video of MultiVid in action [vimeo http://vimeo.com/6315983%5D How to setup and use MultiVid [Thanks tommEE ] Update 9/6/09: We contacted Marco because this app was MIA from the App Store. He responded promptly to let us know that his app is “still in approval limbo”. He’s going to contact us when it is approved and we’ll be sure to pass on the update to you.

Mozilla Fennec Alpha 3 For Windows Mobile Released
Brett Haddock
[ "Cellphone Hacks", "downloads hacks", "News" ]
[ "browser", "fennec", "mozilla", "windows mobile" ]
Mozilla released the latest alpha version of their new mobile browser Fennec for Windows Mobile. It brings many new features and fixes , such as improved startup time and a caching system to help scrolling on a page. They have also added support for a wider range of screen resolutions, and for those of us running an HTC Touch Pro support for zoom via the directional pad has been included in this release. Being an alpha release, it’s still a bit on the buggy side, but is very a promising browser for mobile phones. The final release should give other browsers a run for their money.

80 Gig Drive Inside A Game Boy

https://hackaday.com/wp-…ddrive.jpg?w=470
[_n3o_] put together a nice external storage mod by fitting a 2.5″ drive into a broken Game Boy . This mod fooled quite a few people because it appears that the device still plays games with the drive stuffed inside of it. Sadly, this is not the case. The reflective backing has been removed from the screen and replaced by a piece of paper with a graphic printed on it. The LED from the hard drive was moved to the battery indicator for the Game Boy for added realism. There is no build log for this project but [_n3o_] did give a short explanation of it in a forum post . You can see two more pictures of the project after the break. Update: Take a look inside too!

NES On ZipIt

[youtube=http://www.youtube.com/watch?v=uwxGQhtf4uU] Going even further back in time than 4th gen, [Kevin] tipped us off to this project by [Hunter Davis]. It is a collection of software mods for Zipit’s Z2 instant messenging device. Some of them include allowing it to run (ports of) the Fluxbox window manager , FCE Ultra NES emulator , and (most impresively) the Java framework. The next leap in development, a SNES emulator optimized for the Zipit, is in the works. The Z2 runs Linux out of the box. This means you no longer have to reflash the device to add software, such as DOSbox (also introduced to the Zipit by [Hunter Davis]). Be sure to check out the video demo of FCE Ultra on the Z2 above.

Arduino Muon Detector
Zach Banks
[ "Arduino Hacks" ]
[ "arduino", "detector", "diy", "electronics", "geiger counter", "maxmsp", "muon", "radiation" ]
[ Sebastian Tomczak] was borrowing a homeade muon detector from his friend, and managed to hook it up to his computer through an Arduino. The detector itself uses 3 fluorescent tubes to detect radiation. Three separate tubes are used in order to filter out terrestrial radiation; cosmic radiation will fall in-line with the tubes and pass through at least two of them, whereas terrestrial radiation will only hit one. There is some basic circuitry to amplify the signal and then perform the OR operation. [Tomczak]  used an Arduino to take the raw data and feed it into his computer. He then used Max/MSP to analyze the data and filter out background noise, leaving only the cosmic ray data. He didn’t mention what he was going to use the data for, though. Maybe he’ll hook it up to a synthesizer . Related: Digital Geiger counter [via @ littlebirdceo ]

700 Lumen LED Bike Lamp
Mike Szczys
[ "LED Hacks", "Transportation Hacks" ]
[ "bike", "lamp", "led", "light" ]
We’ve seen bright bike lamps before. This one caught our eye because it needs a heat sink while in operation. [700lumenLED] built a super bright light for his bike that features an aluminum enclosure and heat sinks to protect the LEDs against overheating.  Some nice work was done incorporating the 12v battery into a bike bottle with the power switch and a dimming potentiometer attached to the bottle cap.

Simple Pop-up Notifications
Mike Szczys
[ "Linux Hacks" ]
[ "libnotify", "linux", "notify-send", "popup" ]
[Kristofer] shares a tip on a simple way to add pop-up notifications to Linux scripts . The package libnotify allows you to use the command “notify-send” to pop up a message when you need it. The syntax is simple enough, just place your message in quotes after the command like so: notify-send "Go read hackaday.com" There are a lot of other options that go along with this command such as adding an icon and setting how long the message will be displayed. This would be great for projects that interface through scripts, displaying messages as events happen. For Ubuntu, installing this package was as simple as “sudo apt-get install libnotify-bin”.

Well, there’s an app for that. Check out our suggestions after the break. Here at Hack A Day, we are strong believers in frugality. We think most hackers are. With that in mind, lets start off with our recommendations of free applications to get the job done. These are in no particular order. The iPhone camera: Not only is this free, its already on your iPhone. yeah, we know its not a great camera, but it is indispensable. Taking apart a project? Snap some pics along the way so you can refer back to them when you reassemble. Project ready for testing? Document it quickly and easy with pictures. Project burst into flames on the tarmac? Snap a pic for posterity. We love the camera. Electrical toolkit : Even the most experienced hackers need a little help  sometimes. Need to find the SCR Firing angles this app can help with that. Electronics toolkit : Another app meant to help us find the missing pieces to a circuit. This one has some different circuits than the Electrical toolkit above. iResist : Maybe you never committed the resistor codes to memory, or maybe you’re a beginner just learning. Either way, this appears to be a pretty useful application. Simply select the appropriate colors and it will tell you the value of your resistor. ResistorCode : Another resistor code application. This one has the ability to do up to 6 band resistors. We listed both because some people really have a preference between the text selection or color selection. We like the more robust feature set of this one. LED resist : Who hasn’t been left scratching their head when wiring LEDs? This handy little app will help you figure out what resistance value is needed to keep those LEDs functioning optimally. Runkeeper free : Runners have been raving about this one for a while now. It will track your time, distance, GPS location, and speed. You can view your path on a google map. We’re not exactly sure what project would merit this, but it just seems perfect for tracking rovers or measuring experimental vehicle performance. Though we do love the free applications, sometimes things just merit a little payment. We really only found 2 apps that we thought could be useful enough to pay for when it comes to hacking. Formula Pro : We don’t care how l337 of a hacker you are. You simply can’t know everything. This application is a compendium of the most common formulas needed for Engineering, Optics, Thermodynamics, Electronics and much more. There are over 680 formulas out of the box, with features like the ability to modify and save formulas or even add your own. At 1.99, this is a steal. Accelleration 3d detector : This feature rich acceleration detector will log and chart in 3d your acceleration information. You can even download the results to your computer for inspection. Though we have concerns about the destruction of our iPhone, this just seems like it would be a great tool in a pinch for finding out some acceleration data. Lastly, we understand that no project goes perfectly. Sometimes you are so frustrated and your brain is so fried, you just can’t function. It is times like these that Bubble Snap comes to the rescue. There are no rules, just the soothing pleasure of popping bubble wrap. Careful though, your kids or significant others might get addicted to this one and steal your phone. Well, those are our favorites. What do you use? Did we miss any? The iPhone is supposed support accessories with the latest iteration, are there any must have accessories for the hacker?

Look At Your Gerber Files With Gerbv
Devlin Thyne
[ "hardware", "Linux Hacks" ]
[ "gerber", "gerbv", "pcbs" ]
Tired of making kindergarten macaroni art PCBs? Check your Gerber files before you send them off to a fab house with a Gerber file viewer. Viewplot , GerbTool’s Viewer , and FAB 3000 Free DFM are all free versions of for-pay software to view your Gerber files. If you use Windows and demo software, these are nice options. If not, you can use gerbv . Allied with gEDA , Gerbv is free, open source software that you can use to view all of your RS-274X Gerber files and Excellon-type drill files. Still being worked on with an active development group, gerbv does not have all the bells and whistles, it does have the ability to delete objects. Check it out after the break. “You should always check before shipping or you could wind up with holes in the wrong spots. While you’re at it, a little-known feature is that you can also delete stuff!” -[ zach banks ] To start, make sure you have gerbv version 2.1.0 or later installed with cairo . Copy and paste the following lines into a text document and save it however you like: * %FSLAX24Y24*% %MOIN*% %ADD10C,0.250*% D10* X00000Y00000D02* X10000Y00000D01* X10000Y10000D01* X00000Y10000D01* X00000Y00000D01* X05000Y05000D03* M02* You will now have a simple Gerber file you can view and play with.  Open it in gerbv either through the command line or by starting gerbv and then choosing “Open Layer(s)…” You should now see a rounded rectangle with a dot inside on the right side of the screen. If it is not already highlighted, click on the arrow button at the top of the screen to enter object selection mode. Click around, you should be able to select the various Gerber objects present. You should also be able to draw a selection window to select groups of objects. Pick an object, in this picture it shows the center flash (the dot) selected.  Hit the delete key, and you should get a window that pops up asking if you really want to delete that object. Go ahead and delete that object, that is why you have been provided the little Gerber file. You should now see the flash gone. If not, you should check to make sure you are in the correct layer. You can now save the revised Gerber file. Of course, this is just a sample of what you can do with deleting objects in gerbv.  Hack away!

Ubuntu 9.04 On Kindle 2

[ "handhelds hacks", "Linux Hacks" ]
[ "amazon", "kindle", "linux", "ubuntu" ]
[digg=http://digg.com/linux_unix/Ubuntu_Jaunty_on_Amazon_s_Kindle_2]Having read books on a Palm device for years we were excited when Amazon came up with the Kindle. Our problem is that if you’re going to carry around a portable device it should do a whole lot more than just display text from a few books. [Jesse Vincent] managed to get Ubuntu 9.04 Jaunty Jackalope running on the Kindle 2 . This opens up endless possibilities to run whatever you want on this hardware. The new functionality was presented in a talk at OSCON 2009 . Be warned, [Jesse] has a very high geeky-hacker level. Make sure you have a tech dictionary and Google at the ready when you watch the video embedded after the break. His talk starts at about two minutes in and runs for five minutes total.

Guitar Hero Strum Bar As Guitar Kill Switch
Mike Szczys

[ "guitar", "gutar hero", "kill switch", "playstation" ]
[Ray] had a Guitar Hero controller for PlayStation 2 sitting around. Because he moved on to playing the game on Xbox 360, he decided to cannibalize the older controller for its parts. He removed the strum bar and fit it inside of a mid-1980’s Peavy Patriot electric guitar. Once wired up, it works as a kill switch; it stops all sound from making it to the amp whenever the strum bar switch is actuated. Don’t miss hearing this effect in the video after the break and keep sending in those Guitar Hero mods . [youtube=http://www.youtube.com/watch?v=A6VsLi84WnE] [Thanks Sebastian]

Single Tube Nixie Clock
Caleb Kraft
[ "home hacks" ]
[ "clock", "nixie", "pic", "tube" ]
[youtube=http://www.youtube.com/watch?v=a-7QAWshEXo] This single tube nixie clock cought our eye today. After receiving an IN-8 tube from a friend, [Trax] wanted to find some project to show it off.  He decided on an art piece that doubles as a clock. Tastefully mounted in a simple wooden box with a pretty inlay, the tube is lit from below with a green LED that pulses every second. A single button, located on the back, out of view is pressed to request the time. You can see the time being displayed on the video above. To see the guts and read about how he’s using the PIC16F84’s built in clock to keep track of time, check out his site. Even though this is a Nixie, it reminds us of the Decatron kitchen timer we saw recently. [via Hacked Gadgets ]

Neo-Geo Case Mod
Jake W
[ "home entertainment hacks" ]
[ "Case mod", "genesis", "neo geo", "sega" ]
What do you get when you cross a Neo-Geo and a Sega Genesis? A pretty vintage case mod . [Brett] used a variation of the 16-bit console (known as the Mega Drive II) as the base of his project . With an original Neo-Geo motherboard and a few other components (such as a power indicating LED), the ‘Geosis’ was born. [Brett] removed a few of the unnecessary parts from the mobo , like the power-amp, and set it up to work with a regular 5V DC wall adapter. The PCB also had to be clipped so it would fit into the Mega Drive chassis. Though it may not be the case, some Neo-Geo motherboards in circulation have been salvaged from arcade machines. An enclosure would be essential for protecting them during standalone use – something [Brett] plans to do a lot.

Build An Analog TV Station

With the transition to digital TV , the FCC has abandoned the old analog format. Luckily, you can take advantage of this and set up your own analog TV station . The FCC has a tool on their site to see what channels are open in your area to broadcast in. To broadcast, you need a TV transmitter, but cheap short-range models can be found on eBay or made at hom e [pdf] . Once you have a transmitter, you can pump in a video source, either your own content or videos from youtube. One group, OMGimontv is showcasing popular youtube clips on channel 14 in New York. On their site, users can vote for what clips they want to see. Although this isn’t as simple as making a radio station , it still has a lot of potential. [via BoingBoing ]

Direct-to-PCB Inkjet Printing
Phil Burgess
[ "Tool Hacks" ]
[ "direct", "diy", "inkjet", "pcb", "print" ]
Full Spectrum Engineering has offered up a tutorial for their inkjet direct PCB kits that repurpose direct-to-CD capable inkjet printers (such as the Epson R280) to print etch-resistant ink straight onto copper clad board. This is easier and less error prone than some iron-on methods, especially for two-sided boards. Just print (no need to reverse the design), dry on a hot plate or in a toaster oven for a couple minutes, and your board’s ready for etching ! Homebrew methods exist for all of this, but for those who would rather move ahead with their design than spend time scrounging for the required bits, the kits offer a pretty good value. They can also meet you halfway…say if you’re only lacking access to a laser cutter and just want the CD stencil…all of the parts are available individually or as a complete set: the resist ink cartridge, the stainless steel board-holding stencil, and a supply of double-sided copper clad boards precisely sized for the stencil (3.5 by 2.5 inches). The small board size is well within the limits of the freeware Eagle Light Edition software. Concerned about gunking up your nice inkjet with non-OEM ink? You can dedicate hardware to the job without breaking the bank. Many of the compatible printers are of the “free printer after rebate” bundle variety that can now be found inexpensively on Craigslist or eBay.

Repurpose An Unused Portable CD Player
Mike Szczys
[ "digital audio hacks" ]
[ "art", "cd", "portable" ]
[Ariel] liked the look of the Muji wall mounted CD player . He set out to build his own, posting a how-to that documents his project . The custom paperboard case contains a portable CD player, two portable speakers with amplifier, and a pull-string switch to turn it on and off. With mp3 players sending portable CD players the way of the dodo, and with the proliferation of powered mini-speakers this is a thrift-store build waiting to happen. [via Boing Boing Gadgets ]

Gmail Without The Cloud: Tips For Next Time

[ "google hacks" ]
[ "Gmail", "imap", "labs", "outage", "pop" ]
Yesterday’s Gmail service outage is a hot topic on just about every news site right now. For so many of us that have always taken the reliability of Gmail for granted it was a real shock to lose all of the functionality of the web based system. Now that we’ve learned our lesson, here’s a couple of tips to help you out the next time there’s an outage. Setup POP and IMAP access now Your Gmail can be sent and retrieved via IMAP or POP. These protocols were still working through the outage yesterday but unfortunately you need to use the web interface to enable them. Even if you are not going to use a separate email client regularly, now is the time to set this up so it works for you during the next outage . Use Offline Gmail Yesterday’s outage prevented most users from even logging into the Gmail interface and when they could, the compose message feature was not functioning properly. Offline Gmail, a feature of Google labs , allows you to access the Gmail interface offline. This doesn’t mean that you will be able to send and receive during an outage because this feature still uses the web interface for that. What it does mean is you will be able to read emails that you have cached locally and compose messages to be sent as soon as Gmail is back online. Take a look at what Offline Gmail is all about and see if it will get you through next time.

Simple Automatic LED Lamps

[ "Arduino Hacks", "home hacks" ]
[ "arduino", "AVR", "hall effect", "led", "lighting" ]
[woody1189] put together some automatic lighting for his closet. Nine LEDs are grouped into three lamps and controlled by a hall effect sensor . He prototyped this on an Arduino and then migrated over to an ATtiny85. Although the current implementation could be accomplished without a microcontroller, we’d love to see some firmware improvements such as an auto shutoff for when you forget to close the closet door. The hall effect sensor seems to pop up in a lot of projects so make sure you get a few of them with your next parts order. Video of this in action after the break.

Artist [ Ariel Schlesinger ] has managed to replace an air horn ‘s compressed air tank with butane fuel. This hack manages to change the pitch of the horn slightly, as well as making one very noisy flamethrower. While not as impressive as other flamethrowers , this would probably take the cake for most achievable. Currently the site containing the how-to is down, but we would have to recommend not doing this at home anyway. Video after the jump.

We’ve already brought you a homemade Twitter-enabled washing machine , and toilet , but now a new innovation is being brought to the table by a bigger player. IBM is working on a tweeting television remote, which would allow the user to inform the world what they are watching. Although unfiltered reporting could create awkward situations, the combination of America’s love for television and Twitter is sure to yield interesting results. They also mentioned that it could be configured to report to other sites, such as Facebook or joost . Any ideas why IBM would have in such a patent are welcome in the comments.

Real Time Searching
Caleb Kraft
[ "google hacks" ]
[ "bing", "google", "search engine", "wave" ]
With the fresh competition of Bing, we are reminded that search engines haven’t changed much since Google came along. Bing has made some nice advancements, like video previews, but still has a way to go to be truly different than Google. [Long]put together this prototype of a real time search system based off of Bings API . He was inspired by Google Wave which we hope to see soon. Wave is primarily for communication, redefining how email and messaging would work. We can’t help but think that Google probably has some cool stuff in the secret vaults for searching too.  [Long]’s project seems like a decent start, but like the goodtimes.searchengine , we think it needs some work. What happened to the cool video previews? More importantly, why can’t we turn off the parental filter?

Happy Birthday Internet: 5 History Videos
Mike Szczys
[ "News", "Video Hacks" ]
[ "arpanet", "birthday", "imp", "internet" ]
National Geographic has pegged September 2, 2009 as the 40th anniversary of the Internet. They do not cite their source and our source doesn’t make the same claim . But, August 30, 1969 is the date the first Interface Message Processor was delivered to the Arpanet . The IMP is what allowed different computer networks to talk to each other and so it follows that September 2 is probably an acceptable date to celebrate. To commemorate this glorious day we’re sharing some of our favorite History of the Internet videos. Start with the National Geographic video and then take in the geeky, the new, the old, and the simple. The Geeky: [youtube=http://www.youtube.com/watch?v=V2QdEj8UjBc] [Ethan Zuckerman] walks us through the history as only a geek could. This video starts off with a picture of the guys who invented the IMP which is what facilitated the first information transfer between networks (the Internet). “The Internet as we know it came into being in 1969”. The New: [youtube=http://www.youtube.com/watch?v=9hIQjrMHTv4] A fairly brilliant video presentation of how the Internet developed from several smaller networking projects. Accessible to experts and novices alike. The Old: [youtube=http://www.youtube.com/watch?v=LwQYyUoOA7w] A CBC news report on “The growing phenomenon of: Internet” made in the pre-broadband days. It’s interesting that “the” is missing when they refer to “The Internet”. At 3:25 you can see a lengthy description of what those new-fangled emoticons are all about. The Simple: [youtube=http://www.youtube.com/watch?v=qv0XCaUkfNk] A short animated video that explains IP addresses and how a computer connects to the internet through a service provider.

BrewTroller Brewing Control System
Mike Szczys
[ "Arduino Hacks", "home hacks" ]
[ "arduino", "beer", "beertroller", "brewing", "extreme brewing", "Sanguino" ]
BrewTroller is an open source brewing control system based on the Sanguino . Targeting home beer brewers, this project gathers some of the best features from other DIY brewing controllers and packages them into a hardware and software setup so it’s accessible to those without the skills to design their own. It can interface with 4 heat controllers, 32 pumps/valves, 6 temperature sensors, 3 volume sensors, and 1 steam pressure sensor. The system displays information through a 4 line LCD. It can be used to monitor and maintain temperature during mashing , boiling, and chilling. If you have a more advanced setup that involves automatic valves, it can control those for you with almost limitless reconfigurability through every step of the brewing process. We thought it was pretty hard core that at least some of the kits shipped with hand made PCBs . At the very least, it shows that it is possible to make this board yourself with the provided PCB layout . [Thanks Julius]

[ "led", "life", "peggy" ]
For some, a peggy 2.0 is pretty cool, but simply not impressive enough. [MonsieurBon] felt this way and simply built a larger LED rig for his peggy2.0 .  It still uses the brains of the peggy, but the LED array is a custom built cabinet, using ping pong balls as diffusers. Another interesting modification is that they added a midi port to the setup to generate music based on what LEDs are lit. They say it creates some nice background generative music during the game of life. You can see a video of the system in action after the break. It looks like they weren’t the only ones with this idea. The u:moon project is very similar, meant to be hung from a balloon. There seems to be an issue with the gallery on his page though, so you might want to go to his picasa gallery . [youtube=http://www.youtube.com/watch?v=Zu5ORo3Im1g] [via EMSL ]

[ "blackberry", "browser", "download", "limit" ]
https://hackaday.com/wp-…sqmk4k.jpg?w=450
On the standard Blackberry Web Browser, there is a fixed file download limit of 2.3MB. Many users avoid this by installing a 3rd party browser (such as Opera Mini , for example), but there is still that bitter taste for having an extra web browser around just to download decently sized files. This limit seems to be imposed by a certain WAP port that the Blackberry is set to use by default, which blocks any file greater than this. Fortunately, [0mie] has found a way to reconfigure the default Blackberry Browser to use a different port without this restriction. Step by step walk through, links to the file required, and screen shots of large file downloads are provided. [0mie] claims that this hack works on a number of different phones and OS versions, and we are sure he would appreciate a wider audience to test this with. [Note: This hack seems to use a Chinese provider as a proxy, so there may be privacy issues, etc. As always, hack at your own risk.] [digg=http://digg.com/mods/How_to_Remove_the_Blackberry_download_limit_Hack_a_Day]

Lubuntu 9.10 Alpha Image Available
Mike Szczys
[ "Linux Hacks", "Netbook Hacks" ]
[ "linux", "lubuntu", "lxde", "netbook", "ubuntu", "xfce" ]
The alpha version of Lubuntu 9.10 Karmic Koala is now publicly availabile. The project brings together Ubuntu and LXDE, the Lightweight X11 Desktop Environment . This combination makes for a lighter version of the most popular Linux distribution. Both Xubuntu (which utilizes the Xfce desktop ) and Lubuntu are meant to run well on lower resource computers such as netbooks. With the ISO smaller than 400mb and using quite a bit less system resources Lubuntu looks promising. Right now it looks like the original backup ISO link is down .  If you can’t wait, try this torrent . [via Softpedia ]

[ "avbrand", "carputer", "google maps", "traffic cams" ]
Though not from scratch, [ Avbrand ] integrated a powerful set of tools into his Subaru station wagon. The system was compiled from off the shelf electronics, such as a Compaq notebook, 3G USB modem , touch screen, and an assortment of other peripherals. It is based around Windows XP, though most of the carputer -specific applications, such as backup camera integration, Google Maps – based car tracking , and automatic volume control had to be custom coded by [Avbrand] himself. Perhaps the single most impressive and useful feature of the system is synchronization with highway traffic cameras . The system streams video of segments of the highway before [Avbrand] gets to them, allowing him to make more informed navigational choices. He documents it pretty well on his website .

Zelo, The Improbable Wooden Trike

https://hackaday.com/wp-…/trike.jpg?w=470
The earliest bicycles were made from wood. Nearly two centuries later, some garage tinkerers still turn to this most traditional of materials for their own creations, since welding one requires experience and tools beyond the reach of many. Resembling Gilligan’s Island props, the resulting bikes are both artistic and great fun, but not very practical for real use; often heavy, ill-fitting or lacking durability. [Boris Beaulant’s] birch laminate Zelo , on the other hand, has cleaner lines than anything you’d see in an IKEA showroom. Not content with an ordinary two-wheeler, he’s tackled a three-wheeled recumbent trike, which requires even finer tolerances. Two months and over 1,300 miles later, the trike is still rolling strong through the French countryside, proving its mettle as legitimate transportation and not just a garage novelty. [Beaulant’s] build log (Google translation here ) offers some insights into the development of this masterpiece, starting with prior woodworking projects (furniture, rolling toys and a children’s bike) and finding clever solutions to problems such as creating a mold of his own back for a custom-contoured seat.

Firefox Master Password Recovery Tool

[ "brute force", "cracking", "firefox", "firemaster", "master password", "password" ]
It’s great in this day and age that browsers can remember our passwords for us, allowing us cross-site security without the hassle of memorizing a million different random passwords. It’s great, that is, until we forget our master password. Fret not, though; there is a solution. The folks over at Lifehacker show us how to use FireMaster to recover forgotten or misplaced Firefox master passwords. Perhaps a better solution is to just store those tricky passwords where nobody will find them .

[youtube=http://www.youtube.com/watch?v=T8UzSVFUIc0] [ Moldover ] decided to change up the way CDs are packaged for his album release. Yes, you still get a CD with some pretty sweet music , but the case can also play sounds. He custom printed a circuit board containing some LEDs, buttons, photoresistors, and what looks to be a piezo transducer which all combine to produce a strange whine like noise. But with the included headphone jack, he shows it can be used to produce some very interesting music – reminds us of circuit bending . [Thanks Ferdinand]

You would be hard pressed to find a hacker who doesn’t have in some form a rats nest of wires and cables behind their computer desk. [Antoine] decided to tackle the problem and came up with his custom built cable management system . There is little info, but he does say his setup uses Ikea Antonius coat hangers and some hollow tube. Its quick and wont leave a residue like some cable solutions, so long as you don’t mind a screw hole or two. We especially like how if you need to change your setup you wont have to re-zip tie everything.

I-Swarm Robot Update

[ "autonomous", "i-swarm", "piezo", "piezoelectric", "robots", "solar", "swarm" ]
Back in October we reported on the I-Swarm robotics project . [Travis] sent us some more information. These tiny robots are programmed optically and are able to respond to programming commands via an infrared signal. Locomotion is facilitated with piezoelectric actuators and the power to the units provided through a solar cell. It is not clear that this project is still ongoing as the I-Swarm web page lists a project termination date of 6/31/2008. That being said, the video embedded after the break was posted two days ago showing swarm movement and detailing the programming, testing, and hardware specifics.

Internet Enabled Furby
Mike Szczys
[ "Arduino Hacks", "Robots Hacks" ]
[ "arduino", "ethernet", "furby", "xport" ]
[edwindertien] sent us his project to connect a Furby to the internet . The original Furby controller was replaced with an Arduino which in turn was given ethernet connectivity via a LANTRONIX XPort serial ethernet module. This assigns the Furby an IP address which can then be accessed through a script or via a web interface. Now we want to see someone combine this idea with the arduino that sings “Daisy Bell” to make the ultimate in creepy new email notifiers.

[youtube=http://www.youtube.com/watch?v=lQdqudTzyBs] [Joey] sent us a link to the newest version of his Gameboy foot controller . In the video above, you can see how he uses it to control the loops in the background while he plays his guitar through an 8-bit filter. That is an old video, using the previous version. He tells us that several gameboys were used in the construction. At one point, he had to replace the guts because the music was so loud it knocked his equipment over and destroyed it. We can’t help but feel just a tiny bit of excitement as memories of renting a NES cartridge for the weekend fill our heads when we hear these riffs. His music isn’t too bad either. There is a growing crowd of people that support “chip music”. You can see what looks like a decent sized gathering enjoying a show with a little bit of a history lesson after the break.

Cheap Wireless For Microcontrollers

[ "arduino", "bluetooth", "microcontroller", "reciever", "transmitter", "wireless", "xbee" ]
Everybody loves microcontrollers, including the Arduino , allowing you to create whatever you imagine. That is unless you want to hack together something wireless. Originally you had to rely on the expensive XBee protocol or other wireless options, but no longer. Hobby Robotics found an extremely cheap transmitter and receiver and wrote a quick guide for wiring them up to an Arduino . Now your wireless projects can come to life, as long as you are within 500 feet and don’t mind 2400bps; minor trade offs compared to the gains of wireless freedom. Final note: You aren’t limited to Arduino, we would love to see someone modify this to work with a PIC or other microcontroller.

The Linux4nano project has been working to port the Linux kernel onto the iPod Nano along with other iPods in general. Although the iPodLinux project has had luck with some older iPods, newer models protect firmware updates with encryption. One of the ways they plan on running code on the device is through a vulnerability in the notes program; it causes the processor to jump to a specific instruction and execute arbitrary code. To take advantage of this, they first need to figure out where their injected code ends up in the memory. Currently, they are testing every memory location by painstakingly loading in a bogus note and recording its effect. Each note takes about a minute to test and they have tens of thousands of addresses to check over several devices. Although they’ve cracked the 2G Nano, they still have a lot of work ahead of them. To make it easier, they’re working on automating it with button-pressing Lego Mindstorms-based robots. Dubbed Nanotron 3000 , this line of robots can press the 3 buttons needed to test the iPod. Ideally, these robots should be able to go through over 23,000 addresses a day, which is much more efficient than doing it by hand. With luck, they’ll crack it soon.

[ "midi", "rock band", "xbox 360" ]
[Peter Kirn] over at Create Digital Music takes an in depth look at the process of adding your own music to Rock Band 2 . This involves using REAPER audio production software , uploading your work via the XNA Creators’ Club , and then playing the fresh track on an Xbox 360. Both REAPER and the XNA Club cost money, and the total price comes out somewhere between $100-$160. The process is now in closed beta but a wider beta is expected in September followed by a full release in October.

Snow Leopard Ditches Real Math For Fake
Mike Szczys
[ "Mac Hacks", "News" ]
[ "binary", "math", "OsX", "snow leopard", "storage" ]
We’ve always felt that hard drive manufacturers were dirty crooks because of their use of fake math to make drives sound bigger than they actually are. Here’s a quick refresher for those who need it: Because digital information consists of 1’s and 0’s (two possible settings), digital architecture revolves around powers of 2. Long ago, when nomenclature was setup for measuring data the term kilobyte was adopted to represent 2 to the 10th power bytes (base 2, aka real math). The problem here is that 2^10= 1024 and when laymen hear the root “kilo” they think 1000 which is 24 byes less (base 10, aka fake math). So, if you have a 500,000,000 byte drive, base 10 math would call that a 500GB drive, but base 2 math would call that 476.8GB. We understand why hard drive manufacturers use the base 10 system; larger sounding drives sell better. Now we find out that OSX 10.6 Snow Leopard is using base 10 math to calculate storage space . While base 2 math is the standard storage measurement for operating systems it may at first be difficult to understand why Apple would change to a base 10 system. But think about it once more, doesn’t Apple have a lot to gain if all the storage-containing-hardware they sell sounds bigger than it actually is?

The Metric prefixes are base-10 prefixes. Period. Computer Science used these prefixes because they were close enough, when we first started using them. Error didn’t accumulate that fast when you were talking about 80 meg hard drives. However, the gigabyte/terabyte/petabyte age is here, and those discrepencies are HUGE. Metric prefixes just don’t work to approximate these higher powers of 2.However, saying that 1 kilobyte = 1024 bytes is, in point of fact, incorrect. The metric prefix “mega” means 1000. The correct term is kibibyte – KiB. 1 KiB = 1024 bytes. The fault here is not on Apple – they’re simply calculating a kilobyte as it SHOULD be calculated. The fault lies with the computer science folks for using metric prefixes incorrectly for so long.As for the argument that the meaning of the prefixes has changed and we should keep the status quo – what if ever field did that? What if you had to remember that 1 kilogram was really 1001 grams or 1 micromole was really .000000101? Start using metric prefixes incorrectly and you set a dangerous precedent. Why should a computer be special? Why should 1 kilobyte be 1024 bytes, but one kilo-anything-else be 1000?So good for Apple – call things what they ARE. Use standards (and that’s exactly what they are) correctly. Use KB for 1000 bytes, and KiB for 1024. (you can control-click to get file info if you REALLY want to, just like a Windows box that tells “space on disk”)Now, are they doing this to sell “larger capacity hard drives?” Nope. Go to ANY website that sells hard drives and look at the calculation for GB. Go ahead, I’ll wait. See where it says “1 GB = 1000000 bytes”? Hard drive manufacturers have been doing this for a LONG time now. This is SOP in hard-drive land. All this update in Snow Leopard means is that when you buy a 500 gig drive, it’ll show up in Finder as 500 gigs (OK, a little less because of formatting, but you get the picture). This in no way affects ONLY Apple HDDs – ANY hard drive will be counted in base 10. How is that a competitive advantage to their hardware sales? The only think that will happen is the “actual formatted capacity may vary” footnote will refer to the fact that the disk formatting takes some space, not the fact that disks are sold in base 10 sizes then treated in the computer as base 2.Also, what’s up with this “Real Math” crap? What is that, other than FUD? Yes, computers operate in base 2. So? That doesn’t mean all other bases are incorrect. I guess, since base 2 is the REAL math, I’ll have to go tell all the mathematicians in the world that their work is irrelevant.To sum up:“the term kilobyte was adopted to represent 2 to the 10th power bytes”This was a bad move, ignored what “kilo” meant, and should never have been done.“doesn’t Apple have a lot to gain if all the storage-containing-hardware they sell sounds bigger than it actually is?”HDD manufacturers already do this, as stated earlier in the summary.

Arduino PH Meter
Mike Szczys
[ "Arduino Hacks" ]
[ "adc", "arduino", "glas electrode", "pH" ]
[Carlos] sent us his project that uses an Arduino as a pH meter . In order to sense the acidity or alkalinity of a solution, a glass electrode is connected to the ADC of the Arduino through a fairly complicated calibration, amplification, and filtering circuit . Admittedly, it may not be cheaper or as accurate as some commercial models, but it is an open project and can be interfaced with a computer via USB.

Arduino + Hang Man = Hangmanduino

[ "Arduino Hacks" ]
[ "game", "gaming", "hangman" ]
[youtube=http://www.youtube.com/watch?v=hCa8F8fbHLQ] We saw this nifty little toy today and thought you guys might get a kick out of it.  Its called the Hangmanduino, and as you can probably tell from the name, it plays hang man . This was an exercise in simplicity, you’ll notice there is only a single control for the entire game. We thought that the design was pretty cool, especially the single control. We weren’t surprised to see that this is actually the very same control we featured previously . You can download the code yourself from his website, if you want to make one of your own.

Tiny GSM Alarm System

[youtube=http://www.youtube.com/watch?v=W746qoZsrEs] We’ve covered this sort of thing before, but there is something to be said for the simplicity of this tiny GSM alarm system by [trax]. The alarm system is designed to send the owner a text message when a sensor is triggered. This alarm only works with Siemens phones, but it shouldn’t be too hard to find one .  The alarm is configured via a dip switch on the board and can also be armed and disarmed by text. The brains of this system is a PIC16F84A. The code and schematics are included at the bottom of the page. [Thanks Dario]

Asterisk allows you to be your own private branch exchange ; think of it as your own telephone company. You can setup extensions in your home or office, configure an intercom system, implement a hold system with music, manage voice mail, and integrate Voice over Internet Protocol. Starfish PBX , available in alpha release today, aims to make Asterisk available to a wider user base by simplifying the interface used to setup and maintain the system. [via Digg ]

Update: Foundation PC Cooling
James Munns
[ "computer hacks", "home hacks" ]
[ "follow up", "foundation", "overclocking", "pc", "water cooling", "WaterCooling" ]
[gigs], whose foundation-based PC cooling project we covered earlier, has posted his initial test results . There was a large debate going back and forth in the comments as to whether or not this would work, and hopefully this should clear most of it up. He used a 150W fish tank heater to simulated his system’s heat output, and used a quiet fish tank pump to keep the water flowing. Over 8 hours, he was able to maintain a constant temperature 16° C (61° F). While not quite frigid, this would definitely provide ample cooling for normal operation with some headroom for overclocking. Chart of results after the jump. [thanks to gigs for getting back with real data so soon]

Hacking DMM Tweezers
Caleb Kraft
[ "Tool Hacks" ]
[ "DMM Tweezers" ]
These Tweezers are pretty cool tools for anyone doing SMD components. We tried them out and found them very pleasant well made. They are able to identify components and take readings easily with one hand. One thing they are missing, however, is the ability to measure voltage. The people over at Openschemes decided to see if there was a way around that. As it turns out, the chip used in the unit already has the capability to measure voltage. They take us through the process of modding the unit to be able to take advantage of this un utilized feature . From the outside, the only difference is a new switch to set the mode to voltage. Great job guys. [via Hacked Gadgets ]

Jakob Griffith
[ "Misc Hacks" ]
[ "barcode", "Bokeh", "Bokode", "MIT Camera Culture Group" ]
The MIT Camera Culture Group utilized Bokeh , an effect where the lens is purposely placed out of focus, in order to vastly improve current 2D barcode technology. Dubbed Bokode , the team claims that an off the shelf camera can read data 2.5 microns from a distance of over 4 meters, compared to today’s average barcode reader’s maximum distance of only a foot or so. What looks most interesting is the ability to produce a smoother and more accurate distance and angle calculations (relative to the camera): allowing for a better augmented reality . It also seems to be more secure than traditional 2D barcodes , that is of course until the hacker community gets a hold of it. [Thanks Talin]

Root Labs wrote about ICU64, a Commodore 64 emulator with a couple unusual features. The most special of these is the ability to show the entire working RAM of the system. Each RAM address lights up when accessed. The user can also zoom in or change the values at each address if they want. This sounds complicated, but the demo videos demonstrate the power of these abilities. This would also serve as a great primer on lower-level code’s memory management . Unfortunately [ mathfigure ], the author of ICU64, hasn’t released this out to the public yet, but should be released soon. ICU64 has been released!

Center Brake Light LED Retrofit
Mike Szczys
[ "Transportation Hacks" ]
[ "brake light", "car", "led" ]
[Matt] wanted to increase the intensity of the center brake light on his car. The factory installed light uses a 20w incandescent bulb and although aftermarket LED replacements are available, he decided to take the retrofit on himself. Using the Fresnel lens from the light assembly as protoboard, he mounted a row of 10mm LEDs along with their current limiting resistors. He then broke the glass from the original bulb, removed the filament, and soldered directly to the two electrodes. This way the bulb socket can still be used to connect to the car’s electrical system.

Ms. Pac-Man IPod Charging Cover

[ "charging dock", "ipod", "pac-man" ]
iPod chargers definitely are a unique entity on anyone’s desk. Allowing you to stand your iPod upright, charge, and maybe play a video at the same time, but they aren’t exactly beautiful. [russm313] got the brilliant idea of disguising his iPod (and charger) as a miniature Ms. Pac-Man arcade cabinet. Unlike some other small cabinets we’ve seen, it is just cover and can’t actually be played. But the idea is still original and the process is so simply we’re surprised it hasn’t been done before; just cardboard, glue, and some other small items are needed and you have a work of art. All that is left is figuring out how to adapt it for the iPhone. Check out his iPod playing a video of game play for a more authentic look, after the break.

Beef Up Your UPS

[Surferdude] was unhappy with the decreasing life of his aging uninterruptible power supply . He decided to beef it up using marine batteries . He extended the battery connections outside of the UPS case using #10 wire and swapped the two 12 volt gel cells with the heavy duty lead-acid batteries. Doing so upgraded the device from 20 amp-hours to 84 amp-hours at a cost of about $160. If you’re thinking about taking this on yourself, pay attention to the countinuous output rating of your UPS to prevent a fire risk .

The components (the power transistors and such) are selected to keep cost down and there is usually little spare capacity. Translation? Run them too long and they will burn up, overheat, and possibly cause damage.What about charging the batteries? Almost every single APC UPS I’ve seen has overcharged and cooked the batteries inside (go ahead- open any old APC and the batteries will be distended from excess gas produced while overcharging). That may not be important with a $20 SLA battery from Home Depot- but you probably don’t want to do that with a high end telco battery.Also, when the batteries are discharged, the charging current required to charge them is very high. (Charing rate/current is controlled by voltage- if the charge controller can’t drop low enough the current will be too high). That’s especially true with deep cycle batteries that are heavily discharged. These batteries end up looking like a dead short to the charging circuitry. If the charger is smart (no ups I’ve worked with has ever had decent charge circuitry) then it will carefully control the charge profile to keep things safe (assuming it knows what type of battery it is charging- it probably doesn’t). Instead- the average UPS is going to put out too much current and burn itself, or the battery, up. It may not happen the first time, but it will happen. The odds of it happening go up significantly the more drained the battery is. For those of you doing this- don’t let the battery run down or you can run into problems.If you insist on doing this- make sure you use an extended run UPS, extra large wires (the small size wire used inside a UPS is only for the short runs they have- do not use anything that small to connect external batteries), and for the love of god- keep it outside the house (or at the very least on a concrete floor in a basement).Some day I will document my extended run UPS.

[Matthias] from Intuity Media Lab put together a nice bit on controlling office lights with XMPP from his Android phone. In the article, he explains the components involved in the project, why he chose XMPP, and lists everything you need to replicate it. The project makes use of a wide variety of tools and libraries, weaving together code from multiple languages to achieve its goal. Overall, his project is a welcome change in a world full of Twitter – based solutions .

Wireless Electricity
Mike Szczys
[ "green hacks", "Video Hacks", "Wireless Hacks" ]
[ "batteries", "electricity", "tesla", "witricity" ]
[ted id=619] [Eric Giler] has a talk available over at TED that discusses and demos delivering electricity without wires. Called WiTricity , these methods were developed by a team at MIT a few years ago who were working off of the concepts of Nicolai Tesla . The facts shared about our current energy delivery system are a bit shocking; we’ve spent over $1 trillion in infrastructure and produce more than 40 billion disposable batteries each year. The demonstration in the video starts about 6:30 into it. At first we see a flat panel television powered wirelessly from about 6 feet away, then the T-Mobile G1 powered from the same distance. The thought of new TVs coming with WiFi and WiTricity standard would mean just hanging it on the wall with no cords to run. We can also image cellphones that have a battery only for backup purposes when you were not near a transmitter. The power transfer occurs between two coils that resonate at the same frequency and only that frequency. This remind us a bit of Orson Scott Card’s fantasy communications device from the Ender’s Saga .

That’s why several techniques have to be used. First, have the two coils have the same resonant frequency. Much more energy is transmitted this way. This is the basis of most of Tesla’s work. Second, try to get as much flux to couple between the two coils, and for this you must use collinear coil arrangements like shown in the picture. This makes it difficult to apply to mobile applications, where wireless power is the most needed.Eric Giler lies a little in the video probably to lower the fears of the public.

If it was used now, lots of long range radio communications would be non existent due to the interference.As for efficiency, for wireless power transfer, I suggest using a directional RF method instead of magnetic. This would allow a higher coefficient of transfer due to more energy being received on the device end. This extreme directionality cannot be achieved with magnetics. Using a magnetic system, you will always have alternating field lines, and they will weaken as they go outwards.Yes, this system does use resonance, however, it is still a mutual inductance, open-air transformer.

[Alex] continues to delight us with his projects . His third-generation tiny Braitenberg vehicle , a light seeking robot, is a big improvement over its predecessor, the mini Braitenberg vehicle . He’s moved from an Arduino based design to using the AVR ATtiny25v, replaced the breadboard with a PCB, and reduced the parts count. We think it was a great idea to use shrink tubing to shield the back of the photo-resistors from ambient light. Don’t miss the video of these little guys chasing a flashlight beam after the break.

In November, we covered installing Boxee on AppleTV using atv-usb-creator. [Danny] has written a tutorial on installing Boxee, XBMC, NitoTV, SSH access, and external USB hard drive support . His method installs most of the software via the USB patch stick, then uses the SSH support to enable the external drive and install NitoTV . The tutorial lists a Mac running OSX 10.4 or newer as a prerequisite but there is now a Windows version of atv-usb-creator. According to their Google Code page Linux support for this package is on the way. [via AppleTV Hacks ]

[youtube=http://www.youtube.com/watch?v=3l5DOGn_rFw&hl=en&fs=1&] [denha] has assembled a noise box he calls the XR-NOISE using an XR-2206 multi-waveform function generator . The output has an impressive number of controllable settings, and uses a set of LEDs to indicate sound level and rate. The XR-NOISE uses 1/4″ jacks for both in and out, and can also be controlled by the tap-sensitive mic located on the front of the box. Unfortunately, there doesn’t seem to be any further documentation or schematics to provide context, but it seems that this function generator chip has also been used for other audio hack projects as well, including a scratch-synth using resistive pressure sensors.

Tradewars 2002 Lives

https://hackaday.com/wp-…rs2002.gif?w=470
Are you growing tired of playing all those high-framerate first person shooters? Perhaps you long for the days of blocky graphics and text-based play. You’re in luck because Tradewars 2002 is still around. Many of you will remember this 1980’s BBS based game, playing a limited number of turns per day in an effort to rule the galaxy. The game may be around, but the way you play it has changed drastically. The advent of custom scripts that interface directly with the game system makes this more of a who can write a better script rather than who is better at the game. A hacker’s challenge if you will. Using programs like TWX Proxy or Swath , scripts can be written and executed to perform just about any task you wish. Mapping out the galaxy , automatically trading for profit (cashing), automatically colonizing planets , and much more can all be done automatically. The most advanced script writers have produced advanced team scripts that several people run at once to coordinate team based strategy and hunting scripts that try to anticipate where enemies will end up so they can be ambushed. There are plenty of resources for learning to play the game , the basics of the scripting languages used, and finding servers to play on . Dust off your coding skills and get down to some ASCII graphic goodness.

Arduino + Augmented Reality

[youtube=http://www.youtube.com/watch?v=sxr8oaRUq6k] In this video you can see the marriage of Arduino data collecting units and Augmented reality systems. Set up by the people at pachube.com , a site for sharing sensor information from your location, this is an interesting idea. We can see that each unit has its own pattern, so it can have the data it is collecting superimposed on it in 3d. While this is really cool looking, we’re still trying to figure out what the use of this is? Who is going to be wandering around their office with a camera hooked to a computer? Maybe this is meant more for phones, so you can get quick readings off of the units without having to go access their logs. Since we know how much you guys absolutely love the Arduino, we though you might also be interested in this larger than life portrait we saw floating around. [via littlebirdceo ]

[Jose Torres] sent in his latest attempt at creating a custom Gameboy game cartridge. We’ve featured his projects before, and he’s come a lot closer over the last 2 years. He’s aiming to create an easy interface for homebrewers that doesn’t require any other special equipment. In this revision, he’s using a PIC and a memory controller to interface between an SD card and the Gameboy. The cart also has USB support for uploading files to the SD card and reprogramming the PIC. Because it’s just USB mass storage, it will work on almost any modern OS. He’s currently testing the device, but hopes to be selling them soon for $40.

Ubuntu Repository Crash-course
Mike Szczys
[ "Linux Hacks", "Misc Hacks" ]
[ "linux", "repositories", "ubuntu" ]
[blip.tv ?posts_id=2542951&dest=-1] [Alan] has just posted an Ubuntu screencast that will take you through a crash course in the Ubuntu repositories . If you are new to Ubuntu this will give you a much better grasp on how software repositories are handled. The different types of updates are discussed: Security updates fix bugs that cause a system vulnerability. Updates (generic) are for bug fixes that aren’t a security threat. Proposed updates are for testing before an update hits the ‘updates’ section. Finally, backports are updates from a newer version that have been ‘ backported ‘ so systems running older versions of Ubuntu can have the benefit of newer features and fixed bugs. He also provides some tips on selecting package sources (main, universe, restricted, and multiverse), and choosing the fastest mirror to reduce download times. This screencast is just part one and we hope to see 3rd party repositories , personal package archives , and repository caching covered in future installments.

(CFS), founded by Bill Bartmann, to its demise. However, although Bill Bartmann had lost his company, he had not lost his faith. As Wall Street panicked, lawsuits and allegations rained down on Bartmann, the man who Inc. magazine once said had “remade one of the ugliest industries” and who Fortune magazine said had put a “seedy and inefficient industry on the road to respectability.” In December 2003, after eight weeks of testimony from 53 prosecution witnesses, Bartmann was acquitted of the 57-count indictment brought against him in the post-Enron era by former U.S. Attorney General John Ashcroft. There was no evidence of wrongdoing found.CFS had made its name on its ability to buy delinquent credit card accounts for pennies on the dollar, and then produce nickels, dimes and quarters—an ability the firm eventually took to Wall Street. The accolades and praise for the company never seemed to end: BusinessWeek named it “One of the Top Ten Family Oriented Businesses in the U.S.” while Working Woman said it was one of the “100 Best Companies for Working Mothers.” Inc. magazine called it one of the “500 Fastest Growing Companies in America” for four straight years and the Better Business Bureau gave it the Torch Award for Ethics in the Marketplace.Besides amassing a personal fortune, estimated by Inc. to be as high as $3.5 billion, Bartmann was named as one of Forbes’ “400 Wealthiest People in America,” and the National Entrepreneur of the Year by NASDAQ. He was also awarded a permanent place in the Smithsonian Institute’s Museum of American History, for “Visionary Use of Information Technology” that produces positive social, economic and educational change.Ironically, 17 months after Bartmann’s acquittal and six-and-a-half years after his company was liquidated, the federal bankruptcy trustee (appointed by the U.S. Bankruptcy Court to liquidate the company, forcing Bartmann into personal bankruptcy) issued a report that publicly acknowledged for the first time that, “CFS was not a fraud.” Four independent expert witnesses hired by the trustee in the civil proceedings later confirmed this report.Today, Bartmann just shrugs off the experience that would have embittered most people, and instead is thrilled to have a second opportunity to buy bad debt. This time, however, he is also teaching others what he learned from turning CFS into an empire. (CFS was the first firm of its kind and, to date, remains the most successful debt-collection agency on record).As Bartmann says, “I have seen this movie before and I know how to write the ending. Not only was it incredibly profitable, but we changed the way debt was collected in this country. Compassion was never a part of the equation before. While the process of debt collection is obviously more complicated than simply being nice to those suffering, the business model can be extremely lucrative for those who know how to buy the debt.”He adds, “The market was terribly inefficient then and it still is now, and there’s a giant spread to be made.” History has documented that he was correct: CFS typically collected more than three times what it paid for a bad loan, pocketing an average of 35¢ on every dollar of debt. Those numbers had never been hit before in the history of the industry—nor have they since.Now Bartmann is prepared to do it again, teaching others along the way.For more information and a seminar schedule, go tohttp://www.billbartmann.comAbout Bill Bartmann:Bill Bartmann is the “Billionaire Business Coach.” He is the only self-made billionaire who has devoted his life exclusively to teaching others, and is the leading authority on entrepreneurship in America. He has created seven successful businesses in seven different industries, including a $3.5-billion, 3,900-employee international company that he started from his kitchen table with a $13,000 loan. He has been named National Entrepreneur of the Year by NASDAQ, USA Today, Merrill Lynch and the Kauffman Foundation. One of his companies was named in Inc. magazine’s “500 Fastest-Growing Companies in America” for four years in a row. He has been awarded a permanent place in the Smithsonian Institute’s Museum of American History and has also been awarded the American Academy of Achievement’s Golden Plate Award for being one of the

[ "LED Hacks" ]
[ "burning man", "led" ]
[blip.tv ?posts_id=2542286&dest=-1] These wearable LED toys called Bliplace are freshly made and headed to Burning Man . They’re pretty much just a sound reactive toy, but [Tanjent] decided to go pretty in depth in the design. They are 1″ wide octagons with 3 super bright LEDs and a microphone. The microphone is sampled at 4400 hz by the ATTiny25v and the signal is split into high and low frequency streams. The center LED is low frequency, the sides are the high. They can run a full week on a battery. He’ll be handing out 350 of them at Burning Man, then releasing the source code, boards, and kits after that.

RepRap Wedge

[ "3d printer", "mendel", "prototype", "rapid", "rapid prototyping", "reprap" ]
Generation 2.0 of RepRap, the self replicating 3d printer , is approaching realization. Code named “Mendel” , the new design will be wedge shaped rather than a box which offers a few benefits. The overall design is smaller than the original RepRap but the printable area is larger. This means more functionality with less building material. With each new generation of this project the assembly gets easier and total parts price drops making the RepRap available to a much wider audience. The RepRap blog has put forth some design specs , a picture of the assembled prototype , and has links for general assembly information (ZIP) . We won’t see a finished version of this released for a few months but so far it looks like a big leap forward.

[gigs] was so dedicated to this, he decided to lay 6 meters of copper pipe to use as a radiator in his new house’s foundation. As of now, the foundation is laid (copper pipes and all), and the forum posts come complete with finished slab pics, though there is no house to speak of yet. [via Slashdot ]

All of these items have been dealt with in detail through this thread if you care to take the time to read it but to recap.1. Concrete as an insulatorand will not dissipate heat for the application that I want. Please refer to this:http://www.engineeringtoolbox.com/th…ity-d_429.htmlThermal Conductivity – k – (W/mK)Concrete, light 0.42Water 0.58From here you can see that the thermal characteristics of water and concrete are very similar. Real world tests will answer this one very soon.2. PEX vs CopperAgreed PEX will last a lot longer in concrete than copper. PEX does not have the Thermal characteristics that I want ie it will not work as well as copper to transfer heat into the concrete. This is why I have not used it. I am not interested in this copper lasting decades. I am only after about ~5 years of service.3. Corrosion of raw copper in concretePlease take the time to read the information here:http://www.copper.org/applications/p…_concrete.htmlAbsolute worst case scenario. The copper may get corroded after 5-10 years and expose the coolant to the concrete. SO WHAT do you think I will care by then. Who knows what cooling solutions will be available for computers by then. I will just cut the copper off flush with the floor and move on.4. Concrete slab cracking due to thermal expansionHot water pumped through copper imbedded in concrete and Heating concrete floors hydraulically isn’t a new technology. In the 1930s, architect Frank Lloyd Wright piped hot water through the concrete floors of many of his buildings. No reports of concrete cracking only the copper pipe eventually failing after many decades. These days wires are laid out in the concrete and shorted to heat a slab. On average it takes 6kw + to heat a house slab just a few degrees. Ask anyone that has slab heating and most of the time they turn it off because it costs so much money to run. I am trying to absorb just 150 watts of heat into 2-3 meters of concrete, do the math guys. The water coming off the cpu block will be at the most 25deg. Concrete is elastic and expands and contracts with heat mitigating wear on the copper.Maybe wait for me to get a few tests done before saying how much this is epic fail? If it doesn’t work I’m going to look like an right dick to the 70,000+ people that have visited this thread already.

That much copper pipe, even when insulated, will act like a heat sink any way and will dissipate plenty of heat away from the affected system. Warm water works fine for water cooling; the water coming back through the inlet on the computer case will be warm, at hottest, simply by the length and amount of metal the hot water would have to traverse.This project, having been done before by other people, has shown that it will work fine as a water cooler system at dissipating heat.Retrospectively I think that people concerned over the “thermodynamics” of the situation might just be mixing their units up; Fahrenheit vs Celcius; big differences.Anyway… I still find the concerns over “heat dissipation” laughable, especially given the evidence of similar systems working just fine.", "parent_id": null, "depth": 1, "replies": [] }, { "comment_id": "90052", "author": "eljonco", "timestamp": "2009-08-28T05:04:07", "content": "If you think concrete isolates very well and you need 40 KW to heat your house with floorheating, something is very wrong, or you have to do your math.Proper insulation (‘passive house’) needs 10W/sqm (15KWh/sqm.yr) max cooling OR heating.

We had a pretty quick list of improvements we would like to see, such as the category changes not popping up in new windows, or the new windows appearing on top for that matter. Or most importantly, a way to transition from the fancy preview window to a new tab or window. We are curious to hear your thoughts on this. What would make it better? Is it even needed? Is he building a tool to fix a problem that isn’t there? With Bing showing some nice new features over google, would something like this be of more use ?

PS3 Slim Teardown
Zach Banks
[ "home entertainment hacks", "News" ]
[ "ifixit", "ps3", "ps3 slim", "teardown" ]
The new PS3 Slim has just been released, and ifixit has already posted a teardown . First, they easily removed the included 120GB hard drive, suggesting that upgrading it  shouldn’t be too hard. In order to get inside the cover, however, they needed to use a security Torx screwdriver. In the end, the Blu-ray drive turned out to be the bulkiest component, followed by some surprisingly gigantic fans. Hopefully this means that Sony won’t have to deal with overheating issues .

Push Potentiometer From Spares
Caleb Kraft
[ "Tool Hacks" ]
[ "button", "potentiometer" ]
In an effort to simplify his interface, [danwagoner] cobbled together this push potentiometer . It utilizes a potentiometer mounted directly above a push button with a spring mounted around it. This way the user has only one item to deal with. They can twist the knob and press down on it to push the button.  We love seeing people come up with ways of creating their own items instead of buying something. This was fairly inventive and reminds us of the LED buttons we saw back in January. Great job [danwagoner].

Energy Efficient Fridge Hack
James Munns
[ "green hacks", "home hacks", "News" ]
[ "efficient", "energy efficiency", "fridge", "green", "solar" ]
We’ve already covered a pipe bomb mini-fridge this week, but inventor [Tom Chalko] provides us with today’s fridge hack. He noticed that chest-style (laying down, see above) freezers were more energy efficient when compared to normal stand up refrigerators at the same size, despite the colder temperatures involved. This is largely due to the fact that these chest-style freezers keep cold air in like water in a bowl, even if the lid is open. He has written a very thorough report on his findings (pdf), as well as a detailed walk through of the manageable task of converting a chest-style freezer into a chest-style fridge. In the end, his fridge only used 103 Wh of electricity on the first day to reach and maintain between 4° and 7° C (39° to 45° F), and he noted that 30% of that was just getting it up to temperature. After that, the fridge only turned on for roughly 90 seconds an hour, making it a very quiet fridge as well.

Vonage On IPhone

[ "Cellphone Hacks", "iphone hacks", "News" ]
[ "iphone", "iphone apps", "voip", "vonage" ]
Vonage has promised to release an official iPhone app to compete with other providers such as Skype , and it is currently working its way through Apple’s well documented approval process. Unfortunately, this app would most likely come with an initial cost and/or subscription fee, though a way has been figured out to retrieve Vonage’s SIP authentication information, which would allow use of the Vonage network over other iPhone SIP Clients such as Fring . This solution does still contain the Wi-Fi only clause, but we have ways of making you talk , iPhone. This could also possibly be used on other platforms with SIP clients such as Android or WinMo.

Simple, Low-tech Attack On Credit Unions
Brett Haddock
[ "News", "Security Hacks" ]
[ "banks", "low-tech hack", "malware", "NCUA", "social engineering" ]
The National Credit Union Administration is warning all Credit Unions about malicious hackers and a low tech attack by mailing branches CDs with malware on them. Using a somewhat dated but still effective Social Engineering attack, a package designed to look as though it was mailed by the NCUA is sent to the branch. The package contains CDs with the attacker’s malware on it, and an accompanying letter (PDF) which informs the branches, ironically, about phishing scams. The letter directs the personnel to review the “training material” on the enclosed CD. Once branch employees proceed as directed, the malware is executed and gives the attackers access to the branch computer systems. Credit Unions seem to be targeted because they tend to be smaller local associations rather then larger banks with higher budgets for computer security. When people think computer security, they usually envision high tech systems comprising of long passwords, expensive hardware, and updating software with the latest security patches. However, as famed social engineer and hacker Kevin Mitnick once said, “There is no patch for stupidity”. [via threat post ]

After checking out their site, it turns out that the two are connected in some way, we’re not sure how, maybe just inspiration. The Phasma gives us a little more insight into the construction of the bot. The photos are highly detailed so you can see how the drive works, using the sliding cables to extend the “feet”. It seems quite agile in the video. The drive system, working off of a single cam seems like it would be easy to convert to steam . We would love to see that. [via the pink tentacle ]

Among the courses at this year’s SIGGRAPH (an annual technical conference and showcase of the latest in computer graphics research) was an introduction to 3D scanning that covers all the bases: mathematical foundations, two different build-your-own hardware approaches, and how to process and render the resulting datasets. The presenters have assembled all the course materials on a top-notch web site featuring slide shows, complete source code, and an extensive round-up with links to both commercial and homebrew 3D scanning gear. The simplest of these methods requires nothing more than a webcam, halogen light source, and a stick! SIGGRAPH and 3D scanning have been highlighted many times on Hack a Day, but we’re swelling with pride now seeing an academic venue give a favorable nod to the DIY hacking community (on their links page). Okay, so Hack a Day isn’t called out by name, but just wait’ll next year!

Interfacing A Digital Rotary Switch
Mike Szczys
[ "Misc Hacks", "Peripherals Hacks" ]
[ "electronics", "optical encoder", "pic", "rotary", "rotary switch" ]
[hw640] has put together a well written and detail packed explanation of how to interface with a digital rotary switch . These digital opto encoders have just two outputs with four possible logic levels (00, 10, 11, 01). The relative position of the switch is insignificant but the direction of rotation is what matters. The short and dirty: Each of the switch’s 2 output pins is attached to a pin change interrupt on the microcontroller. Every time the switch moves it generates either a rising edge or a falling edge on one of the two pins; both edges cause an interrupt. By checking which pin caused the interrupt, then comparing the logic levels of the two pins after that interrupt, we can determine the direction the switch was rotated. Although this explanation uses a PIC and code written in PicBasic Pro the concepts are discussed in the abstract and would easily be adapted to an AVR or another microcontroller of your choice.

HTPC Inside A Cellular Phone
Mike Szczys
[ "Cellphone Hacks", "home entertainment hacks", "Video Hacks" ]
[ "Case mod", "htpc", "xbmc" ]
Reader [Jani] always wanted to throw a PC into an old school cell phone . He based this around the extremely small Commell LS-371 motherboard which measures just 146×101 mm (~5.9×4 in). He found room behind an existing access door for a DVI connector and audio in/out.  He even incorporated an OLED screen, secondary sound card for “speakerphone”, and a WiFi connector into the handset. Things start to get interesting when he decided the SSD was too large and needed to be removed from its case. The one thing that seems to be missing here is an IR receiver for a remote but since he plans on running XBMC, he may already be setup to use another option such as an iPhone to act as a remote interface .

What looks like a potential WMD, requires a huge power supply, and has several fans and wires dangling off the sides? Why a mini fridge of course! Your cubical buddy at work may have a Perfect Coffee Mug , or a USB powered fridge but it wont be as large of a caliber as [CaptPikel’s]. Little information about it is out thus far, but an Instructable is promised. We do however know that it uses 3 peltier coolers (assumed to be 60watt each) and can cool down to 46F while being underpowered! If only it held just a few more cans .

Arduino Based Synthesizer

[ "Arduino Hacks", "digital audio hacks" ]
[ "arduino", "dac", "synthesizer" ]
[Jacob] is working on his final project for the Copenhagen Institute of Interaction Design .  Based around Arduino, the quality and quantity of his build notes make this a fascinating read and there are several examples to listen to . The project features a brilliant idea for input:  He uses a 1/8″ TRS connector (mini-jack) whose tip is the input to the DAC of the Arduino. There are conductive pads in the shape of a keyboard that you touch the tip of the connector to in order to complete the circuit. Alternatively, the other two conductors on the connector deliver power and ground for easy interface with external controllers. He built an example controller that uses an LED and photoresistor to alter the signal returning to the Arduino. Put your hand in front of the light and the sound changes. [via Arduino: blog ]

BlackBerry Storm 2 Teardown

[ "blackberry", "cellphone", "leaked", "mobile", "photos", "piezoelectric", "storm 2", "teardown" ]
Photos of the BlackBerry Storm 2, both inside and out, have been leaked. Engadget provides us with the specifics , going into detail about the four large piezoelectric pressure sensors that sit underneath the screen. It looks as though the screen will still function as a button, just without the physical movement of the previous model that received mixed reviews. For a better explanation of the technology behind the phone’s innovative screen, here’s a video describing it in more detail and a writeup over at the CrackBerry forums .

Google Maps Adds Arterial Traffic Monitoring
Matt Schulz
[ "Cellphone Hacks", "google hacks", "gps hacks" ]
[ "google", "google maps", "mobile maps", "mobile phone", "traffic", "traffic monitoring" ]
Traffic monitoring has been available on Google Maps for some time, but has been limited to highways and major roads. According to the Google LatLong blog , traffic tracking support is now available for smaller surface roads in select cities . The data is gathered through mobile phones running My Location. Anybody wishing to help out can sign up their phone and opt into My Location to participate in the anonymous data collection. Now you won’t have to gamble on whether or not your back road alternative route is congested when there’s construction on the freeway. Dash tried something similar with their two-way traffic reporting, but we’re guessing that Google’s version will have even better performance thanks to a rapidly increasing install base.

As an added bonus, zooming will be a much better experience (no “blurry” map showing until the high res tiles are loaded – you simply get more information arriving and polygons getting more detailed.). It would also have the other big advantage you wouldn’t need “zoom levels” anymore, and you could adjust the text size and detail level. You could also easily turn on and off data layers like contors.The barrier to implementing this at the moment I suspect is IE’s lack of decent vector graphics support, and the lack of optimisation in all browsers for displaying frequently changing very complex documents without significant delays – it’s more effort to render a svg vector image than a png image, because the png image is cached as a bitmap when it gets downloaded, whereas in most cases this isn’t practical for svg.", "parent_id": null, "depth": 1, "replies": [] }, { "comment_id": "89498", "author": "cptfalcon", "timestamp": "2009-08-26T01:01:08", "content": "I see no reason not to support scalable graphics, it can always fall back on the previous raster version in cases of incompatibility.

[ "arduino", "design", "pcb", "schematic", "software" ]
Fritzing is an open source project designed to help you move from a prototype to a finished project. Aimed at those basing their projects around Arduino, you start by building your physical prototype, then recreate it with Fritzing software’s graphical editor. From there you can generate a schematic, PCB artwork, and PCB production files. [thanks CH]

Propeller Platform
James Munns
[ "Arduino Hacks", "Misc Hacks", "Tool Hacks" ]
[ "arduino", "microcontroller", "propeller", "prototype board" ]
[nmcclana] has posted an assembly walkthrough for an Arduino-style prototyping board for the 80 MHz, eight core Parallax Propeller Microcontroller . While not board compatible with Arduino shields like the ARM-based Maple board we covered , it does have that familiar layout, and provides access to all 32 I/O pins, and the 3.8″ x 2.5″ footprint was kept in mind to allow easy creation of shields modules that can be designed using ExpressPCB’s miniboard service. The Platform Kit also has the advantage over other Propeller kits such as SchmartBoard’s offerings , which require soldering of surface mount parts. Kits are available at Gadget Gangster , and ready for your next design that needs a little more sauce than the Arduino can offer.

[Guus] sent in his project where he put a radio inside of a rock . He started with a 1970’s car stereo and encapsulated it in cement by wrapping it in duct tape, building a wooden form around it, and pouring in the wet cement. Three ports are included on the back for power, antennae, and speaker. He included an outline of how he did this but we’d love to hear some tips on how he made it look like a rock and not just a brick of concrete .

WiFi Mapping With A Smartphone
Brett Haddock
[ "Cellphone Hacks", "iphone hacks", "Wireless Hacks" ]
[ "apple iphone", "gps", "iphone", "mapping", "smartphone", "wifi" ]
Not so long ago, mapping WiFi required a laptop, GPS, a big antenna and Kismet/NetStumbler. Today’s smartphones have replaced even this task. For those of us running a GPS and WiFi equipped Windows Mobile phone, WiFiFoFum is an excellent and simple solution, as well as a great companion for installing an AP. Start up WiFiFoFum, put your phone on the dash and let it collect the locations of the APs you find while driving around. You can then save the file in several formats: XML, txt, Wi-scan, POI Database, MemoryMap, Netstumbler, and even as a KML File for Google Earth/Google Maps. We have also found it to be a really handy tool for setting up WiFi in a large area, to help find the best home for the router which provides the best coverage. WiFiFoFum is also available for the iPhone via the App Store.

Twitter As A Botnet Command Center
Matt Schulz
[ "News", "Security Hacks" ]
[ "botnet", "command center", "infostealer", "jaiku", "malicious", "malware", "tumblr", "twitter" ]
The folks over at Arbor Networks were browsing Twitter and discovered something very strange: a Twitter account seemingly posting gibberish. At least, that’s how it appeared at first. Upon closer investigation, they discovered that the profile was posting base64 encoded links to PKZIP archives. When they extracted the contents and unpacked the contained DLL and EXE files, they discovered that the account was posing links to malware that would post user information back to certain URLs. The article was also updated to show that the scheme wasn’t limited to Twitter, but also affected users on Jaiku and Tumblr. It’s a bit scary to see that all malware isn’t as blatantly obvious as we usually would think it to be.

Open-Frame Digital Clock
Caleb Kraft
[ "home hacks" ]
[ "clock", "tube" ]
Here’s an interesting project from several years ago. The clock design itself isn’t too noteworthy, but the construction is definitely inspired. You’ll notice that there is no breadboard or PCB, the frame actually is the circuit . The tubes he’s using are Numitron tubes,  which aren’t as high voltage as Nixies or even VFD s.  This means that there is only 12V maximum going through the exposed rails. He discusses some possible future upgrades such as LED or Nixie or VFD, but since this project is a few years old, who knows if he is still working with it. [thanks Agent420]

SpiderBot Emulates Spider-man

[youtube=http://www.youtube.com/watch?v=uBikHgnt16E] Spiderbot moves with four magnetic grapplers that it can launch, detach, and aim according to it’s path planning algorithm. While the robot is definitely not a final product and is quite a bit away from moving with the same grace and speed as our friendly neighborhood Spider-Man, it is definitely one of the more interesting locomotion experiments out there. The video has some nice slow motion footage of the main mechanisms as well as screen captures of the path planning. [Via BotJunkie ]
