HackIt: New Uses For Old CRT Monitors
|
Will O'Brien

[
"HackIt"
] |
[] |
[atrain] wants to know if we’ve got any thoughts on things to do with old CRT displays instead of giving them away or recycling them. We’ve seen
pic programmers
and
oscilloscope projects
, but even I’m curious to see what you guys have to say.
So, got a better idea? Let’s hear it.

"content": "I have a cool idea, but don’t know if it works, a X-ray machine :)CRTs are shielded, but produce some x-rays.Accordings to wikipedia, they are allowed to produce up to 0.5 mR/h at a distance of 5cm. A disagnostic x-ray requires about 1.4 mGy, which is about 100mR. So about 200 hours. Of course its not thatsimple: e.g. x-rays from CRTs are softer, modern CRT usually produce far less radiation than the limit, maybe its not enough to distinguish it from background radiation ….But maybe its enough to show the existence of the x-rays to expose a film (for many hours) sticked to the CRT (with some cardboard to shield the light).If that works: try to reproduce simple pattern cut out of lead foil, or paint patterns with the right input AV-input or oszi-input, and finally try to x-ray some small (thin?) stuff. :)))Older color CRT should work better, higher acceleration voltage is better (but DONT tweak it to produce more radiation).",

"content": "While in college I would go to thrift stores and purchase old green screen monitors. Apple Monitor iii (yes that’s 3) and even an early Mac. I’d then open them up, cut the wires leading to the deflection coils, and then wire them into either series or parallel (different monitors/axes worked better with one or the other) with the speakers to my stereo.So basically I made a very inaccurate oscilloscope.This produced analogue visualizations way before winamp or iTunes did the same. In fact, I wrote an iTunes pluggin a few years ago to simmulate the effect.I had a Led Zeppelin bootleg that at one point would actually draw a pretty clear guitar on the screen. Unfortunately the instrument being played at that moment was a harmonica, but it was cool.For those that are less adventurous, if you have an old monitor/tv with a composite (RCA) input you can simply plug in a speaker wire and you’ll get a banding pattern that throbs with the music.I had two monitors mounted about 12 feet high in my dorm room in college, one throbbing and one doing the oscilloscope thing. People would bring CDs buy to see what they looked like. Ben Harper was always impressive, as was Dark Side of the Moon.",

"content": "alex,Note: the following is potentially dangerous. crt screens can hold a big charge for a long time after being unplugged and can serious mess you up or even kill you. what follows does not contain any safety information so if you don’t know what you’re doing then don’t mess with this stuff.Steve’s description is pretty similar to what I used to do. While I did use the vertical scan signal at times to produce a more traditional waveform, I found that using one speaker to drive the horizontal and one to drive the vertical made more interesting patterns. basically I’d find the wires that go to the two coils at the back of the tube. If they could be unplugged I’d unplug them but sometimes I’d just cut them. I did this on probably 5 different montiors for various people and it was always a bit different.Anyhow, after cutting the two wires leading to a coil I’d then take a wire leading from my stereo to my speaker ($200 sharp all in one from a big box store, nothing nice) and wire the coil either in series or parallel with the speaker. Sometimes series would work better, sometimes parallel would. Then I’d do the same with the other speaker and the other coil. Again, each coil was different so I might do parallel on one and series on the other. Whatever produced the most deflection without going off the screen. I’d be playing music through it the whole time and turn it on occasionally to test.So in the end I’d have the left speaker doing vertical deflection and the right speaker doing horizontal. When sound was coming out of both speakers I’d get crazy spirograph type patterns. When sound was mostly out of one side or the other the patterns would be mostly horizontal or vertical. pink floyd would have lots of transitions from one to the other.The patterns were always very reactive to the music, unlike many visualizers in itunes or whatnot. more volume made for bigger patterns. bass made for big loops, higher tones for tighter loops.I should note that one monitor I did this to started smoking almost immediately. I assume this is because the power that should have been going from the sawtooth waveform generators to the coils for h and v scan was now not going anywhere. if I had been more sophisticated I’d have measured the resistance of the coils and put resistors on the wires coming out of the board to replace the coils.Again old Apple ][ and c=64 monitors always worked. I sent a friend a Mac classic modded to plug into his stereo for his birthday and he still has it and it still runs 10 years later.I am in the process of putting together a website that will host my software projects. I’ll include the iTunes pluggin that mimics the green screen effect and the winamp pluggin that I wrote if I can find it.Given that my current project combines wiimote head tracking with laser pointer detection for a fps game (I’ve got it all working but need to add polish like explosions) I’m thinking that you might be interested in posting a link to the site when it goes live in a few weeks.",

So you could reflect the image off a mirror, of course, and still have it legible. Why would you want to do that? Well, perhaps to make a teleprompter, or to make a video chat display that puts the camera right behind the apparent screen so that the communicating parties can look directly at the screen and at the camera at the same time.",

I’m sure they can hear that sound perfectly clear, so you could train them to do stuff based on when they hear the sound. You could wire the AC into a solid state relay (or just hook it up to a DPMS screen saver) to make a computer turn the sound on and off (if say you want your dog to come back inside every night at 7pm)",

D200 Hotshoe GPS Redux (el Cheapo Version)

It’s been a
while
since we talked about putting a GPS on top of a D200. [Rick] sent in his
latest
version. He used a nice 20 channel sirf III gps from spark-fun, a cheap D200 remote cable and a few parts to send the NMEA sentences down the wire. The biggest improvements include taking the $100 Nikon cable out of the mix and swiping power from the camera for the GPS board. All the info is there, but I had to seriously stare at his wiring instructions for a while despite the low parts count. I like to see actual circuit diagrams!

Binary POV Watch

[
"Misc Hacks"

[] |
I probably won’t be replacing my giant G-shock watch just yet, but
this
binary POV watch is pretty sweet. Sure, the POV clock is old hat by now, but it’s also a nice example of adding a Li-ionbattery to an embedded project. It uses a MAX1555 li-ion charger and throws caution to the wind and doesn’t bother with any external capacitors. Battery life is several days or several hours if the watch is put into flashlight mode.

I stumbled on
this
simple, but effective and cheap diy guitar pickup in my rounds for interesting hacks. Piezo elements haven’t failed to amaze me. They’re usable for electronic
drum kit
, underwater microphones,
running shoes
and musical greeting cards.
(I’ve only found an old, out of print book on hydrophones, so if you’ve got a good reference,
send it in
.)

HackIt: Better Project Documentation

"HackIt"

[] |
Today’s hackit is devoted to everyone who enjoys a good project write-up. I’m on the verge of upgrading my photo gear (Digital Rebel XTi) with some new lighting and a better lens to improve my work and found myself wondering what the community likes to see in a good how-to. What can be done to make them better for the community. Decent photography? Better parts lists? I prefer good photos and reproducible work.
So, got a better idea? Lets hear it.

"content": "Clearly, something has to be said about Instructables. As awesome as the site is (I’ve been a member since only a few months after it started), one thing that bothers me is the manner in which picking pictures for your projects is carried out. I think pictures are a really important part of documentation.As I see it, you document a project for two reasons only: to learn from your mistakes and to reproduce your successes. You need to write and speak clearly, and explain what you have done or are doing fully. Think about how you figured out how to do this, and how you can help someone else do the same.Pictures are really helpful in this regard, especially since writing about putting pieces together is almost impossible. These needn’t be high quality poster shots, but they should be in focus. In fact, a smaller picture is often better as people really don’t want to wait for a download. Thumbnails or preview images are key.I have given many lectures to middle school students, and I find that thinking about explaining something to them can be the best way to explain it to anyone. You’ve probably seen some of my projects before, but if you’re interested in seeing how I personally document check out my projects page:http://mustardhamsters.com/?cat=4Although it isn’t finished yet, you may also want to keep up with my modular room control project. This is a two year long effort that is just now being polished, and many of my current projects are actually modules or pieces of this larger effort:http://mustardhamsters.com/?page_id=194Documentation is hard, but you need to do it not only to share your work with other people, but to see how to improve your current projects and see potential for new ones.",

"content": "Most of the important points are already taken but to take it a step further and talk about _WEB_ documentation specifically I think there are two very important aspects to consider1. keep everything on a single page that can be viewed by a browser and indexed by a search engine. If you MUST break it up across multiple pages then ensure that the title, current step, and keywords associated with the project appear on all pages. It’s also preferable that you host it somewhere it can stay for the forseeable future.Attention college students: that uni provided hosting wont last past graduation, and neither will your project’s legacy if you don’t host it elsewhere.3. All files should be in a platform independent format. If you’ve got an Eagle PCB schematic, great, zip that up for people, but also provide them with a .jpg, .gif, or .pdf so they can view it right in their browser. you have source code? great, throw that in a .txt outside of the zip as well so people can view that too. Everyone viewing your documentation via the web will have a web browser, so it’s a good idea to ensure that all of your documentation can be viewed by a web browser… it’s pretty simple really.3. Google use the alt text in html image tags to label images for their search, be sure to put the project name and useful information about the project in there if you want those pictures to get indexed.4. If you took some pics with your digital camera at it’s full resolution and left them that size and with the generic naming… that can be great for detail but do us all a favor and instead of hyper linking to 100+ generically named images, size them down physically and dimensionally and display them on the page with links to the full size photo.5. Not realy web specific, but good and more specifically consistant formatting is important. Some rules to follow for formattinga. tell them what you’re going to tell them, tell them, and then tell them what you told them. title the project appropriately like “how to build a dohicky” or “modify your widget for bluetooth”, provide a brief description about the goals of the project, what topics the project will cover and what it wont cover. Tell them the kind of tools, materials, and prior knowledge they’ll need to accomplish the task (if a tutorial), then go through all the steps, then wrap it up by explaining what it all means and what the results should be like.b.keep the steps or sections to a manageable size, have the breakup of steps make sense, and keep them small enough that someone could read a section and retain all of it for 5-10 minutes while they try to do it without having to keep going back to the step. Don’t make them so small however that you insult the intelligence if your reader.c.use strong visual cues to break up the steps, with a consistent numbering and formatting scheme throughout. If someone needs to glance back at the page to read something they don’t want to have to scan through buckets of text to find their place again (this comment is exempt because I don’t have control over the formatting :p ).d.understand the knowledge level of your reader and write to that, don’t over explain the basics if you’re writing about an expert topic, and don’t make ANY assumptions about what a beginner should already know. Also use appropriate vocabulary for the intended audience and never use slang, an acronym, or an abbreviation without explaining it at least once in the documentation (preferable the first time you mention the term).Thats all I can think of for now.",

Pictures are useful for the “oh gee, a scratch, was that there before?” as well as the simple explanation of what the part looks like outside and on the inside. Since digital cameras makes imaging so easy, and we have memory cards that hold thousands upon thousands of pictures, there’s no reason not to take a lot of pictures.That being said, it’s also important to fully explain the details of what you’re making.

With nearly 25 years in electronics engineering I don’t need anyone to hold my hand; just please take a paragraph or two (links are fine) to provide background and explain why I should care what you’re doing. Hackaday is good for this; the linked sites are sometimes much less so.As I’ve learned time and again from my own mistakes, try to anticipate the redundant time consuming stuff for your readers. 5 minutes of my time is NOT worth more than many accumulated hours of my readers’ time. Include clear photos and diagrams, simple explanations, complete parts list with suppliers and estimated costs, list of tools, required and suggested utilities.As with any prose, try to emulate those authors (and hackers) who make docs that are not just precise and instructive but are fun. And, add links to similar solutions if available, especially if they’re commercial solutions (to rub it in).",

[Ed] sent in his
latest
iPod modding effort. Previously he did this on a
4th gen
, and now he’s following that up with a 5th gen version. He found an even smaller bluetooth module for the mod, but it requires replacing the hard drive with a compact flash card to make room inside the case if you want to keep the original back cover.

If you haven’t gotten a chance yet, do
watch the video
of this attack. It’s does a good job explaining the problem. Full drive encryption stores the key in RAM while the computer is powered on. The RAM’s stored data doesn’t immediately disappear when powered off, but fades over time. To recover the keys, they powered off the computer and booted from a USB disk that created an image of the RAM. You can read more about the attack
here
.
How can you reduce this threat? You can turn off USB booting and then put a password on the BIOS to prevent the specific activity shown in the video. Also, you can encrypt your rarely used data in a folder on the disk. They could still decrypt the disk, but they won’t get everything. I don’t think this problem will truly be fixed unless there is a fundamental change in hardware design to erase the RAM and even then it would probably only help computers that are powered off, not suspended.
The potential for this attack has always been talked about and I’m glad to see someone pull it off. I’m hoping to see future research into dumping RAM data using a USB/ExpressCard with DMA access.

OS code would have to be written to send electrical shorts to the RAM in sleep modes (there goes your desktop)or the power off switch and mobo would have to have a circuit that shorts the ram…probably not good for the RAM…there is nothing that shows this would be effective. RAM is a charge coupled device, And even if the BIOS zeroed anything that would take time on computer shutdown, even if a computer was left on you can still yank the ram out in a powered state.",

"content": "Step 1:Modify/Create encryption software so that it can detect when the OS has been locked either via the user or automatically. Then after 10/15 seconds (depending on user settings), have the encryption software isolate/protect itself in a small area of memory (if not done already), while re-encrypting the rest of the RAM with the original key. Then overwrite (with random data) the area of memory in the isolated section that stores the key.This should be able to be done via the software in a few seconds. The only way to restore the session would be for the user to enter their encryption password, which would return them to the OS’s lockout screen, whereby they would have to enter their user account password within 10/15 seconds or it would again re-lock/encrypt.While this method isn’t perfect, it does offer increased security. The only way of getting the data/key then, would be to shut off all power to the machine quickly before any OS lockout occurs, then boot the machine to your device or remove the RAM and place in another machine to boot to your device. See next step for increased security.Step 2:The software could modify the BIOS to force a full RAM test (RAM fill) every time the computer is booted (force it to occur before any booting can take place). This will fill the RAM with random/null data as part of the test, thereby wiping any retained memory before anyone can boot into any device to make a copy of the memory.This eliminates someone quickly shutting off power to the machine and then quickly booting into their device to copy the memory. But it does not stop them powering off the machine, spraying the RAM to cool it, removing the RAM and inserting into another machine that will boot to their device. So again, it is increased security but it is far from perfect.Step 3:Implement specialist hardware to solve the remaining vulnerabilities, for example:RAM that loses all of it’s memory upon power loss within 5 seconds at room temperatureA machine case that requires a key to open, so nobody can access the internal hardware without damaging the caseAn internal mechanism that can tell when the machine case is being tampered with (unauthorized access) and upon detection will wipe the RAMAlternative Option:Create/Modify encryption software to store the entered key onto a hardware key e.g. a USB drive, rather than in the RAM. If the USB is removed the encryption software (in RAM) will either lockout the user, shut down the machine, or wipe what is in RAM (except itself) before then shutting down. This will eliminate anyone getting the key from the RAM, but does not protect the unencrypted data still residing in RAM. Also the additional problem is introduced of the USB drive becoming the vulnerability; perhaps have a special purpose USB drive that uses a type of fast fading RAM rather than flash. So if it is taken the memory will fade quickly, and if the drive has a secure housing, it would be difficult to obtain any residual memory as they would not be able to get to the chip quick enough to cool it or copy data.Conclusion:All these ideas need refinement, but a combination of the above methods would make it exceptionally difficult to obtain the user’s key or data. Some of the options are cheap and easy to implement, others are not. It all depends on how much the user is willing to spend. Spend enough, using most of these options and nothing will get your data except an extremely well planned attack, or a vulnerability presented due to user error (e.g. easy to guess pass key / user not watching who is watching them / user leaving a machine with extremely sensitive data unattended…. etc).",

Tin Hat Bonus: Jetlag Got Me.

Update: Sorry guys. I hadn’t seen it before, but apparently this dell keylogger junk is a rather delicious
hoax
. To keep from confusing the RSS readers, I’m leaving a post stub up. If I wasn’t travel-beaten I would have paid attention to the fact that the supposed keylogger wasn’t on a flexible flat cable. I pulled the image since it was originally stolen.
It’s
probably
totally BS, but supposedly
this guy
found what seems to be a keylogger inside his new dell 600m laptop. He submitted a FOIA request to the DHS, only to have his request denied. It’s a bit tin-hat, but the idea that a three letter agency might be adding extra hardware to your laptop is very disturbing indeed. I guess it’s time to start auditing any new hardware purchased for bonus parts. [

[nickjohnson] sent in what might just be the most incredibly
evil
alarm clock ever. It’s a fairly simple pic project with a PIC, LCD and input buttons. When the alarm goes off, you have to solve math problems before it will shut off. If you answer correctly, you make it stop. In my case, I’d probably add a mute button that can be held down while you do the math. Source, schematics and pcb layout are provided.

I caught up with [Larry] from
pauldotcom.com
and got a quick walk-through of his Shmooball gun. After several less successful attempts, this one worked pretty damn well and featured a distinctive sound that caused a notable glimmer of fear in the eyes of the speakers.
*cough*[renderman]*cough*.
Read on for the secrets of the Shmooball gun.
The gun is pneumatic, so pressure was supplied from a 7-800psi CO2 paintball gun through this quick disconnect. [Larry] needed an adapter to connect to the 1/4″ regulator input. He made the small chamber, with each connection, and found that it acted as a helpful expansion chamber for the gas supply.
The lower pressure storage chamber is fed about 100psi from the regulator. To release the pressure to the firing chamber, he used this electric water sprinkler solenoid. These take around 12VDC and slightly slow the pressure expansion into the firing chamber
The trigger was built using a simple safety mechanism – two momentary push buttons have to be depressed to fire the sprinkler solenoid.
The get a good seal on the Shmooball, he cut down a beer cozy to act as reusable wadding.
The wadding fits quite well around the 2.75″ Shmooball. The twine keeps the wadding from going the way of the Shmooball.
A velcro mounted laser pointer provides quick aim for chasing tricky speakers.
Thanks to [Larry] for giving us the tour!

"content": "I’ve made quite a few Pneumatic Air cannons… the absolute *best* trigger mechanism is a custom “diaphragm valve”. I can’t really find any good links on the subject (I don’t think many people actually build these) but basically you have the barrel and then a substantially larger dia but shorter piece of pipe that goes around it to form the air chamber. the back ends are matched up with the large tube getting sealed around the outside of the barrel on the firing end. Looking at the back end it would be like a circle inside a circle with the barrel in the center and the air chamber around it. A sheet of rubber is placed flat against both of them and glued as well as nailed to the larger diameter pipe so that the center of the rubber just rests on barrel.A pinhole is put in the rubber to allow air to trickle into the chamber created by the larger tube and the outside air then an end cap is placed over the whole end creating a small pocket of air on the outside of the rubber. A 1/4″ or larger valve is placed directly on the end cap, this is used both for filling the cannon as well as firing. this valve can be hand operator or an electric sprinkler valve, it wont matter.As you fill it air builds up in the small end cap chamber and once the pressure is high enough it will seep through the pinhole and fill the larger tube chamber around the barrel as well.Once it’s filled when you release the valve all of the air rushes out of the end cap chamber and creates a vacuum causing the rubber to get sucked back into the end cap and breaking the seal against the barrel allowing all of the air in the larger tube to rush directly into the barrel all at once.This works exceptionally well for larger applications with 2″ or larger barrels since you can use a 4″ or 6″ air chamber and the value goes from completely closed to completely open an order of magnitude faster than a sprinkler valve.We also made a version that used a piston as opposed to the end cap chamber so the release was completely mechanical. this worked just as well but required some precision machining to size and seal the piston properly.",

I have a golf ball cannon that was built around a 4″ piston that i built myself by hand (i.e. with a belt sander and some files, i wish i had a lathe!)pistons have the advantage of huge airflow; a diaphragm is limited by how far it can flex, whereas a piston just moves out of the way entirely. if you can build a piston that can open fast enough, you can realize some pretty wicked pneumatic power. they work in a similar fashion to the diaphragms.my golf ball cannon with the 4″ piston had a sprinkler valve pilot, which was itself modified for pneumatic actuation, so the sprinkler valve would open very quickly, which dumped the pilot volume behind the piston very quickly. the result? golf balls moving at 500 feet per second.theres a nice little app somewhere on the web that will calculate the muzzle velocity of pneumatic cannons. i think its called gas gun design tool, but its been several years since i’ve used it. its worth a look if you can find it.",

"content": "Twisttedsymphony’s right about the diaphram valve cannons, but a much simpler improvement would be topot up the exhaust hole for the solenoid, attach a hose to the valves upper chamber with a brass fitting, and attach the other end to an airgun (like the type you’d attach to a compressor)its not as fast as a piston or diaphragm valve, but you’ll be amazed at how much better it performs than with the solenoid (plus you won’t need batteries)Lastly, I should note that if you need to maintain the electronic triggering (ie, for remote control or something) another simple modification is to seal the hole just past the threads on the output side of the valve, then drill a 3-4mm hole in the internal vent line (this is usually on the side, just beneath the surface directly above the aforementioned hole) basically, the valve normally vents the upper diaphragm into the output to intentionally slow opening times and reduce water hammering. By venting the upper diaphragm straight to the atmosphere, the pressure above the diaphragm can drop more quickly, which will noticeably increase the speed of the valve.(In case you haven’t guessed, air cannons have been one of my biggest hobbies)Anyway, good luck.",

ShmooCon 2008: Hard Drive Highlights

Today wrapped up with a talk on recovering data from solid state hard drives by [Scott Moulton]. The talk focused on the differences in data storage between SSD and platter technology. I did come away with a few interesting bits of knowledge. In an effort to extend device life, flash based drives store changed data to a new location, leaving the old data intact until a garbage removal subroutine gets around to clearing it out. Probably the best way to recover data from them will be altering or replacing the controller chip so you can access old data.
Yesterday I caught an interesting talk on recovering passwords from drive images by [David Smith]. He found that he could take a system image, strip out all the strings that were stored by various programs and use them to build a dictionary of possible passwords. By limiting string lengths and matching for known password policies, he was able to further filter his dictionary for likely passwords.

[Nathan] sent in
his
toaster oven reflow controller. He’s using a Triac to drive the heating elements, a thermocouple to monitor temperature and a PIC controller to run the show. I’m giving him extra points for style on the control pad. Hopefully he’ll have time to put out a complete write up when he’s got it finished. You can check out the project photos

I played with the articulation one, but not the 2nd–because I’m not convinced they’re needed at all. I had a lot of success with a $20, 2 burner, no convection small oven by just turning it on max, waiting for the joints to reflow, counting to 15 and then opening the door all the way.If you look at recommended temperature profiles from paste / component manufacturers, they have guidelines for the various zones (pre-heat, soak, reflow, cool down) of a typical reflow process that include things like max. temperature rise, etc. Typical numbers are 3 deg. C / sec ramp up and 6 deg. C / sec cool down.In my testing, the toaster ovens couldn’t come close to the heating limit, and opening the door wide open at the end didn’t violate the cool down rate, either. Temperature was measured with thermocouples in air and also cemented directly to the PCB.So, from the toasters I’ve played with, there’s no need to throttle the toaster with a controller since full power “on” is about as close as you’re going to get to the recommended profiles as possible. Not to mention that a toaster oven is not a very controllable system in the first place–the controller isn’t going to be able to cool it down automatically without some mechanism to open the door and blow air inside.My first oven was a larger, 4 burner convection GE (1440Watts) didn’t work at all, whereas the smaller $20 (1000 Watts) one worked great, probably because there was less volume to heat. From what I’ve read and experienced, you want something that can go from 0-200 deg C in about 5 min.All that being said, I’m sure there are situations where a controller is helpful. For instance, if you have big connectors (plastic or metal) or other large components, or BGAs, and the profile is somewhat critical to achieve reflow on all the parts without burning or melting others. This applies more-so to lead-free. While I doubt the controllers can achieve a particular profile on the first pass, through trial and error you could arrive at something workable, and then have it re-played without personal involvement. It’s nice to easily record the profile, too.Anyone have a case where they actually needed a controller?The cool button on this guy’s controller might outweigh all these arguments.Here’s an expanded writeup of my toaster oven experience, with a summary of common reflow profile regions and requirements:http://www.curiousinventor.com/guides/Surface_Mount_Soldering/Solder_Paste_and_Toaster_OvenThe relevant parts of industry reflow specifications are in this pdf:http://www.intersil.com/data/tb/TB389.pdf",

ShmooCon 2008: Unauthorized Phishing Awareness Exercise
|
Will O'Brien
|
[
"cons"
] |
[] |
[Syn Phishus] presented a pretty interesting talk. At $former_company he prepared and executed a rogue internal exercise designed to heighten awareness of phishing scams. (That is, attempts to gather personal information from users with trickery.) After noting a certain lack of effort on the part of security policy implementation, he put together an official looking email, set up a simple phishing site that
didn’t
actually store any collected information and set loose the dogs of war. OK, he actually sent it to a select group within the company without warning
anyone else
ahead of time. He purposely didn’t store any of the results to protect the foolish, but he estimates that maybe 10% of the recipients fell for it.

ShmooCon 2008: Intercepting GSM Traffic

Back in August, [h1kari] presented an
analysis of the A5 crypto spec
used in GSM systems. Almost all GSM conversations in the US and Europe are encrypted using this standard. At the time they were still in the planning stages of building their rainbow table of shift register states. Today we heard an update on the progress. The whole space is 2^58 in size and would take a standard PC 33,235 years to calculate. Not being patient people they built a box containing 68
express card based FPGAs
. Each one is capable of doing 72 billion operations per second. So far they’re one month into the 3 month process. Once the table is completed any person can crack a GSM conversation in 30 minutes using 1 FPGA and the 2TB table. They do have plans for building an optimal system that would be based on solid state drives and 16 FPGAs that should do the crack in just 30 seconds.

"Wireless Hacks"

This
project got some blog love last year, but it slipped past my radar. [jhecker] built a parallel port interfaced device based on a Cypress 2.4ghz transceiver module. The module is pretty complete, so as long as you can wield a soldering iron, you can pull this one off. The module is pretty cheap, so it could be just the thing for building your own signal detector.

Shmoocon’s Coming

"cons"

Just prepping up a bit before this spring’s
Shmoocon
. Things will definitely be colder this round, so bring your cold weather gear if don’t want to arrive in the form of a human popsicle. I’m a fan of Shmoo’s
organization tactics
. Running several single session talks keeps me from missing one
great talk
to attend another. [h1kari]’s GSM talk promises to be interesting. Not to mention VOIP penetration testing and solid state hard drive recovery. [Eliot] and I will see you there. Don’t worry, we’ll be reporting back for the guys that have to miss out this year

[Micheal] developed
this
board to be the heart of an
even bigger
sensor interface project. I think the design might come in handy for someone looking for more flexibility than even an Arduino or similar projects offer. The SAK2 uses a 40Mhz PIC 18F452, step down power regulation, RF transceiver and plenty of I/O ports. Firmware, schematics and BOM are all provided.

Scrying EM Fields
|
Will O'Brien

[
"Misc Hacks"

[] |
I’m still trying to wrap my head around
this
one. The idea behind
scrying
is to reveal hidden data – i.e. electromagnetic fields within a structure. (Like those created by a metal building/computers/etc) It does have other uses besides artistic – it can be used to analyse the 2.4ghz spectrum among other things. It looks like an interesting project, despite the odd description. (Lets just say that it’s an eccentric bit of reading)

Window Unit Turned PC Water Cooler

I almost passed
this
one up because it was shotgunned across a few blogs, but it would be a shame to pass up on a good hack. [Mike] decided to use a standard window AC unit to cool the CPU in his rig. The A/C unit was modified to place the evaporation coil inside a fish tank filled with glycol/water antifreeze coolant. To cool the CPU, he used a normal water block, but insulated the coolant lines between the cooling unit and the machine. That should give you the idea. For more details, have fun deciphering his
project in pictures

Bonus: [Johnny] sent in the NASA workmenship guide. It’s pretty interesting to see what the space boys require for their electronics work.

As far a metering device sizing using capillary tube it’s just some really simple math (even easier when you use a thermal expansion valve or a pressure expansion valve for tuning). I used R290 and a 1/4hp compressor, slapped one together in an afternoon, and running in a vac on low side i get idle temps of around -40 centigrade on my dual core opteron.",

EeePC Inverse Video Scaling

[Tracker] sent in
this
handy software hack for the eeePC. The idea is to scale higher resolutions like 1024×768 down to the native 800×480 screen resolution. His post tells you how (but requires windows) and helpfully provides the required downloadable driver. I wonder if he’s seen
this
video showing up 1600×900?
(update: fixed the missing video link.)

Cheap 360 Degree Head Tracking

[Joel] sent in
his
efforts to build an inexpensive 360 degree head tracking display. He’s using a Playstation six axis controller as the key to his helmet tracking system. The demo is short and to the point. He’s using the usual
Glovepie
driver to provide the software interface and what looks like off the shelf hardware on the helmet.
What really grabs my attention is the low cost of getting into VR now. Assuming that you own a computer, you can build your own VR setup for the cost of a Playstation controller and a cheap heads up display. (Remember
these
?)

Yaw (rotation) is calculated with the gyroscope and is easily calibrated if you understand how to program in glovepie.3. the HMD that i used it technically off the shelf, the casing is from an old VFX1 VR helm that was gutted and retrofitted with a (very) cheap evertek HMDi’ll be making another video soon, and i’ll post it my website eventually.-joel",

Personal (IR) Radar

Will O'Brien

[
"Misc Hacks"

[chris] sent in
this
inexpensive personal radar project. It uses a servo mounted IR range finder to locate and display the distance to an object. (Lake a parked car as shown in the demo video) The project is destined for some robotics projects – and who doesn’t love LED display proximity sensors. It makes me think of the direction finders in every other 80’s action movie. It’s gotten some attention on Digg, but I like it for the inexpensive build and the excellent use of a PIC 18F452.

nice how-to on gutting the 2.5″ LCD from a $20 mini dvd player. After removing the player hardware, he shows where you’ll need to tap the circuit to feed it composite video. Looks like just the thing for those portable console projects.

DMX Light Control For Home Automation
|
Will O'Brien
|
[
"home hacks"
] |
[] |
Generally, the only time I’ve ever seen DMX in use is for stage productions. [Dan] sent in
his
home light control project – he used a RS-232 to DMX interface and a bunch of commercial DMX dimmers. His light switches were replaced with potentiometers connected to the system via CAT5 cabling. The POTs send 0-10v up the line to the dimmers, and the manual control can override the automated(DMX) settings. The system is simple, robust and responsive – avoiding the delay pitfalls usually incurred by systems like X10.

Also, there would only be 1 line going to the control unit, not both the pot and the light itself.Still awesome though.",

The goal of using both DMX and the 10volt signal was to allow in room control as well as automated.in a normal household dimmer, the pot controls pulses to determine ‘on time’ (maby its off time, I dont *exactly* remember).In order for the automated server to take over, an override switch would need to be added to the dimmer module, in order to route the automated signal to the triac and bypass the pulse signal from the module’s internal logic. This would involve complete dissasembly of the module and likely some extensive mods (at the very least, cutting wires/traces and adding a few components.)Ultimately, it would be cumbersome, as the home user would almost always leave the switch in ‘room control mode’ for practical daily living.a completely custom made dimmer module might be a better solution, but at the very least requires bi-directional talk (dimmer to server: “someone is turning my knob. dont dim me out.”) and would be an expensive, ‘per knob’ solution.All in all, a pasive remote as done here is the *best* solution (tried and tested in thousands of performance spaces around the world.)",

To switch the light back to auto you push the button and the backlight tuns off.This would let you have a software ‘admin’ app which could toggle the manual/auto state.

"Misc Hacks"
] |
[] |
Look ma, it’s my retina. Here’s a short collection of hacks to make yours happy.
[Brian] sent in
this
odd collection of information he calls the open source biohack kit. The info is interesting, but everything is inside a giant zip file. I think it could benefit from a better online presentation.
[insomartin] sent in a simple design to create a
USB piezo drum pad controller
. The parts count is pretty low and the drum pads are created using the usual DIY piezo speaker sensor.
[Emilio] sent in
his
Nokia phone turned SMS remote control project.
[Ian] over at diylife
put together
a handy USB analog gauge interface.
[Jock] sent in
something similar
, but this time the project uses gauges from a car for driving games.
In order to continue mocking Boston, [doug] sent in his
moononite
project.

The best part about the procedure is it doesn’t require dilation and you have a backup of the data. Otherwise the doctor has to make notes and diagrams (not very accurate) of what is going on. This you can compare side by side. But wait there’s more….doctors often email Bill, the author of the best books on retinas, about any image and he gets back with them to help provide better care. It’s a great test, but many MD’s don’t like it because they think people will use that to avoid a dialated exam. I work in an opthalmology practice, I hear both sides all day long.",

this
electric ball valve he built for his bio-diesel reactor. If you haven’t checked, the commercial versions are pretty expensive. His solution was to mate a salvaged saturn wiper motor (sans control board) with a polypropylene bolted ball valve.
Oh, and happy birthday to me.

Pressure builds up behind the valve and the valve suddenly fails to operate to relieve the pressure. Reactor vessel breaches, spews bio-diesel as both liquid and gas. Then they meet a method of combustion, and voila, you don’t have a house anymore.But, low pressure system, it’s not likely to happen, so whatever floats your boat.Mac",

For my processor a poly valve is perfect, in other cases a brass or stainless valve may be a better choice just like anything else choose what fits the job best.

Luckily, the hacker knows what he’s doing and won’t be doing anything crazy with it.I’m sure the ball valve is a wonderful piece of engineering, -the problem is that it is being controlled by a salvaged piece of equipment-.“Should” is not a word that is used in process control. “Should” costs millions of dollars in damages and could kill people. “Should” causes disasters like the Texas City Refinary incident, the Tacoma Narrows brigde collapse, and the Columbia Space Shuttle disaster.I really need to stop coming back to this thread.Mac",

Cellular Data Controlled Robot

[Jatinderjit] sent along
the latest
in LEGO robotics. The cell phone controlled robot. It’s based on a LEGO Excavator kit with a few spare parts via ebay. The controller is a Nokia phone running a small webserver. A PIC 24F microcontroller runs the show as it receives commands via the phones IR interface. The phone uploads images from the on-board camera as fast as it can update it. Think of it as a poor mans
mars
earth rover.
FYI, This puppy made engadget while I was working it over, so the site might get a bit overloaded in the near future.

this
voice controlled video game project. The idea is simple and honorable: make gaming accessible to the physically limited. [Cyberpyrot] used a voice recognition kit and interfaced it with a bog standard XBox 360 controller. Looks like a fairly easy project if you’re familiar with the pointy end of a soldering iron.

(compared to when driving). also, the brake, accelerator, clutch all seem to be quite different when parked or when driving.i think what i’m trying to say (i know nothing about car mechanics…) is that all of the available “controls” in the car are linked mechanically, hydraulically, pneumatically (or however) to other pieces.of course, I have no experience with car mechanics, so i could be totally wrong, but i think that even if steering/accelerator/etc did output an electrical signal based on their state, they are still linked mechanically to their respective… stuff…that said, it would be quite neat to see, and i think i saw in popular science a while back some japanese concept car that allowed an in-built driving simulation to interface with the car’s controls.",

Tengu Clone Redux

"Misc Hacks"

[] |
Remember the
open source Tengo clone
? [jfmateos2] sent in his version, with a custom candles game designed for birthday giving. It’s a nice piece of work, and I love it when we inspire new projects! He sent in a nice write-up of the features he added, so I decided to post it in its entirety:
[Hello, my nick is jfmateos2 and this video
http://www.youtube.com/watch?v
=MnFP4FNVE-I
is a brief presentation about my last project devoted to PIC microcontrollers.
The video is in Spanish but subtitled in english. When I first saw the cloned Tengu developed by Alex featured in Hackaday blog, I thought it was a proper project for learning the use of PIC microcontrollers´ specific functions like A/D converters, interrupts and timers. After studying the features of the original Tengu developed by Crispin Jones, I started to specify the requirements of my own clone. I decided to include a basic game intended to transform it into a personalized birthday gift; my sister´s birthday was near.
Its usage is very easy. After connecting PIC-Tengu to a USB port, it will switch on in a sleep state. Blowing on its face he will wake up. Then PIC-Tengu yawns and, if and only if it is the first time we use it, it will start the candles game. The aim of this game is to blow out the candles one by one, so it can become quite boring if the person being honoured is over a certain age, although less painful than pulling his/her ears. Fortunately, my sister is only 25 years old. A personalized scrolling message appears when the game is over. Next, PIC-Tengu starts to imitate every noise it hears. There are four sets of faces available: aquiline-nose, snub-nose, no-nose and Luciano. The active set of faces changes blowing or with a strong noise. Pic-Tengu´s Auditive acuteness is configurable through the back potentiometer. Pressing this button toggles between the imitate mode and the scrolling message mode. If we keep the button pressed more than 2 seconds, PIC-Tengu will reset, recovering the same state as if it had never been used before; this implies that the candle games will appear again after awakening it.
Last, if there is no activity in the imitate mode for more than 5 minutes, PIC-Tengu will fall slept. The brain of this project is a PIC18F2455, whose pins directly activate the LEDs matrix´s rows. There is only one LED column active at any given instant, also determined by the PIC18F2455´s pins, but this time using an intermediary ULN2803. The signal captured by the microphone is amplified using an LM358 before reaching an analog input in the PIC.
The firmware is written in CCS C, and the PIC has been burned using the parallel port version of GTP Lite and WinPIC800.
Electronic schematic, PCB artwork, source code and compiled firmware are available for download in

Hackit: A Better Homebrew Control Interface?
|
Will O'Brien

[
"cnc hacks",
"HackIt"
] |
[] |
I’ve built
a few
CNC controllers, and I’ve been a bit disappointed by the state of the control interfaces. Most diy systems rely on a parallel port interface, while a few use a serial connection.
Just one
that I’ve seen has an actual USB interface, but it’s limited to use with the fab@home software for now.
So what’s the hackit of the day? I think that the hardware hacking, home fabrication community could really benefit from a standardized I/O interface for driving CNC machines, robotics or anything else along those lines. For CNC work, it’ll need a serial or parallel port emulation scheme to allow existing software to take advantage of it. For quicker home development, some simple API’s for controlling the device would be excellent. Imagine using perl to develop robot logic with just a few easy function calls…
Hackit is really your show, so
lets hear your ideas

When configured right, you can use a relatively small and simple circuit, run it off USB (with serial port emulation or full-speed), and even use a boot-loader to program it (no more needing that programmer after you get it going). There have been people experimenting with the boot-loader in non-windows environments, I know, but I haven’t really explored these.This is what I’ve been using to run most of my projects lately — especially with their samples program, it’s a fairly cheap option. Plenty of I/O ports, libraries for PWM, a decent amount of memory, wide operating voltage and the student version of their C18 compiler (with MPLab IDE integration) is fairly full-featured (completely full-featured for the first 90 days, if I recall correctly, then there are certain limitations). I’m actually already looking at using it for a CNC interface — I’ll tell you how it goes.",

This is good since my experience is that, given complicated protocols, many manufacturers will screw them up or (worse yet) roll their own.I also like serial because I can use hyperterminal (or z-term or kermit) to talk to the device when I need to test something. No (invariably broken) special tools that won’t install under my OS, no (usually insufficient and/or brain-damaged) APIs written in Visual Ada.NET.I use a laptop that has no serial port, but the usb-to-serial adapters work really well. If you insist on USB, the USB Bit Wacker seems to have things basically right. It presents itself to the computer as a standard modem device which you then talk to with normal serial using normal serial tools. Works on my mac, works on my pc. Folks running Linux seem to be able to use it fine.9600 8,N,1 please. No flow control. If you’re doing something that 9600 baud won’t keep up with then by all means, go faster. If not, please don’t. If you’re doing something that 115k won’t keep up with, then there is a really good case to use USB along with all of its associated nasty issues.Okay, I feel better now. Thanks for listening.",

Bootable USB RAM Capture
|
Will O'Brien

[
"computer hacks"
] |
[] |
Inspired by some research done at
princeton
(looks like the original site is down), [Wesley] sent in
his
version of a bootable RAM dumping USB drive, complete with a how-to on rolling your own. He put together a utility that runs under
syslinux
to capture the data, installed it to a USB thumb drive and managed to create a device that will boot on a machine and copy the contents of the RAM before it’s overwritten by another utility.

Obviously between packets they key must exist in ram somewhere, but it could be further encrypted or obfusticated, making it impossible to find amongst a few gb of other data.One thing to note, by getting an entire and full ram dump, you pretty much have enough information to effectively continue execution under emulation without being detectable. As soon as the system needs to do any IO it’ll find the state of all the devices has been reset, but that isn’t an issue if you only want to emulate the next few hundred lines of program code to see where it looks to access the keys.",

[nophead] put
this
creation down to its final resting place, but it still deserves some attention. A Motorola MC6809 ran the show while a stepper driven robotic arm tipped with a suction cup fetched the selected disc. [nophead] has an interesting
blog
covering his work on building a 3d prototyping machine. The goal is to use it to produce a reprap, but he does a nice job of covering design problems and his attempts to solve them.

(at the same time, you’d have to find a liquid polymer that quickly solidifies under visible laser light).it’s important that the polymer (‘glue’) be liquid and flow quite well until it’s exposed to a focused beam of laser light. since you kinda build the 3d object in a tank of polymer one layer at a time, and progressively decrease a platform down into the polymer such that the top of your 3d object is just below the top of the tank, you need the polymer to flow very easily around the hardened sections, and to rinse off them pretty easily when the printing is complete.",

9V Battery As A Project Case

Will O'Brien

[
"Misc Hacks"

[] |
I stumbled on [Carlos]’ blog while I was hunting for Arduino ideas.
This
simple IR detector caught my eye – not for the project, but for the project case. He stuffed his IR detector inside an old 9V battery case. The TSA probably won’t like it, but it’s a fantastic idea for those smaller projects.

Urban Sound Experience

[Christiane] sent in
a project
prepared at the University of Applied Sciences in Würzburg/Germany. The idea is to experience urban sounds at various heights in a variety of cities. As feet are detected on a step, the experience changes to simulate an increase in altitude. A pair of surround sound headphones, some proximity sensors, an Arduino and instantaudio make everything work.

Add On-board Light Metering To Your Nikon D40
|
Will O'Brien

[
"digital cameras hacks"

[] |
Nikon didn’t build a light metering chip into the D40. That’s fine if you’re using one of their auto lenses with the on-board chip. [Matt] decided to
add a sensor
to his camera and try it out with his manual lenses. His writeup is a bit challenging to get through, but if you’re really into Nikons, you’ll make it. He had to tap into the ribbon cable inside the body, mount the extra hardware, and add an additional switch outside the body to allow the chip to be turned on and off. The extra sensor adds a bit of a step to taking the shot, but it’s the sort of thing that’ll become second nature pretty quickly.

I’ve used it with a 135mm 2.8, a 50mm 1.8 and a 35mm 2.5 my dad used to own, all with good results. Canon do exceptionally well in this regard – an EOS + adapter can be used in Av with one of these lenses, while on a Nikon body (even something like a D300) it can only be used in manual.Nikon started off with everything in the body when they went AF. Canon moved focussing to the lens, but kept everything else body-side. Now, Nikon are moving across to everything-in-the-lens mode. Not sure why. Canon seem to have it at about the right level of body-lens co-operation. Things like IS can’t be done very successfully in body, while metering clearly can be.",

The adapter also allows you to use a shit-ton of lenses, every Nikon lens I’ve put on it has worked great. Lenses from the 70’s ’til now work fine.

This means the lens will work, but the body cannot meter properly.The more modern af lenses communicate with the body electronically and the more expensive bodies often include the mechanical bits needed to work with the old lenses.The Nikon system has a lot of backwards compatibility built in, even though functionality might degrade a bit as the lens and camera become more mismatched. This means that all Nikon lenses made since 1959 will work on my ultra-cheap and hitech D40, except they won’t do autofocus (of course) or meter.Compare that with Canon, where nothing made before 1987 will work at all on a modern body.The hack itself is still pretty awsome of course :)",

D40 menus have an override for that. All we really need is a “meter anyways” override in the software.Maybe there is a simpler hack, involving covering or shorting some pins on the lens/camera interface…",

SMD Component Strip Cutter

[ErikH] sent in this sweet little device that he and a studymate put together from some spare parts to measure and cut strips of SMD resistors for one of their
student organizations
. The stepper motor and LCD were salvaged from a printer, an ATMega8 drives it, and a servo drives the cutting mechanism. The video’s not very exciting, but it shows a decent demo of the device.

[Jock] sent in
this
photo gallery showing a Lego Mindstorm automated microscope. I dug up
the paper
that was published about this hack to find out just what the idea was. It’s a proof of concept showing off automated data collection – the Mindstorms are used to allow the intel QX3 microscope to take data over a grid area. It’s an interesting idea for collecting time series data. The computer interface is a bit overly complex, but the Lego’s make this sort of project accessible to the amateur roboticist.

After reading the latest hackit post, [Ben] sent in
this
older, but simple logic analyzer. The software was written in windows, but the circuit is simple enough, and most hackers I know have more computers than immediate family members. The circuit uses a HC245 octal bus transceiver to feed the 8 data lines on the parallel port. (You can use a variety of chips for this application, most CMOS buffers will probably be fine.)

I’ve found in my designs on the 14bit pics, that I have to update the PWM when my ” 1 byte cycle counter” wraps to zero rather than immediately. You are clocking at a higher clock rate (I use 4-8mhz internal clocks with up to 10 PWM channels), so your design may not be so sensitive.Recently, i’ve given up on the PIC and it’s goofy architecture and moved to the Cypress PSOC parts. They are really neat with dedicated digital and analog blocks. You can set up up to 16 PWM (actually I use pseudo random bit sequences, which have less flicker) outputs, and the C compiler is really reliable vs the buggy stuff i’ve experienced w/ the pic (though the PSOC compiler generates crap code). The PSOC has it’s own shortcomings, such as a really inefficient CPU, but the digital and analog blocks more than make up for it b/c stuff is done in HW vs SW. PSOC is really fun, esp when u wrap your head around it’s way of doing things.",

"HackIt"
] |
[] |
By popular request, I’ve added a hackit category. Today’s hackit is one of my coffee shop creations. Considering the quality of work we’ve seen, I can’t help but wonder… If the Hack-A-Day community were to come together and produce a joint collaborative hardware project, what could it build? A modular robotics platform? A digital I/O platform for other projects? If you could harness the power of thousands of hardware hacking geeks, what would you ask them to do?
Got a better idea? Let’s hear it.

Money comes and money goes… but the amount of time invested to become a hacker is both large and irreplaceable.I’d like to see a single, unified document that serves as an introduction to hardware hacking. Assuming a knowledge of math up to functions, there’s no reason a sufficiently dedicated person couldn’t be introduced to hardware hacking within their spare time over a few months, and for under 200$.Dev platforms are also great. I’m happy to see someone got the AtMega microcontrollers to talk to flash memory cards. Maybe we could make an Atmel development board that lets you load programs for the Atmel to compactflash instead of using the STK500 or equivalent? If it could also write to the compactflash in a sane way, and have free pins and analog to digital converters, then we will have successfully reduced the complexity to entering the microcontroller world (yes, I know atmel has some usb flashdrive/microcontroller products, but we can do better). Graduate students around the world would also have a universal datalogger which can be programmed to produce output already in a .csv file, which would be damn cool for us SAS or R users.",

It pluged in where the 16 channel inputs were on the l.a.Finally the third was a speed doubler for the l.a. (80mhz l.a. but cut channel count to 8 (4 out, 4 in? or was it 8 any way you want?). again, it pluged into the input/expansion connector of the original unit)The whole set was pretty impressive, and not terribly expensive. I think the main unit would have set you back about $50 to $80 at the time. Kudos to james barbarello for all the hard work!So, not to burst a bubble, but its been done (and very well I might add).However, I would like to suggest reviewing this series and then comming up with a vastly updated (esp USB and software) model based on this design (with the same goals.. I.E. speed, channel count and a wide enough voltage range so as to avoid blowing the device if you hook it to the wrong end of your circuit.",

Hey- Our Scope could, with a little effort, address external memory to make it a persistence oscilloscope. Imagine the possibilities if we throw in a module for flash memory extensions, USB connectivity or Signal generation!",

Replace Your LCD Power Supply

[Computer Guru]’s LCD power supply went out, making it a useless pile of plastic. He used an old computer PSU to
replace
the defective one. After he identified the outputs on the built-in supply (The one’s I’ve pulled apart were labelled) he stripped down the replacement PSU to provide the necessary voltages.

It’s a fairly simple matter of changing the voltage divider on the sense input to the regulator IC. Unfortunately you can only change the voltage on one line; the other lines will all move up or down in voltage in proportion. The ratios of the voltages to one another are determined by the windings in the power supply’s transformer, and only one output is actually regulated; the rest just follow it.",

RGB PIC Color Changer
|
Will O'Brien
|
[
"Misc Hacks"
] |
[] |
[Ian] put up his RGB LED color changer project over at
diylife
. It’s a pretty simple project, but well designed and flexible for combining with other projects. He used a PIC18F2550 to drive everything, and some FETs to drive the LEDs. When you connect a USB cable, the color cycling project stops and the PIC responds to simple hex based color commands.

I’ve found in my designs on the 14bit pics, that I have to update the PWM when my ” 1 byte cycle counter” wraps to zero rather than immediately. You are clocking at a higher clock rate (I use 4-8mhz internal clocks with up to 10 PWM channels), so your design may not be so sensitive.Recently, i’ve given up on the PIC and it’s goofy architecture and moved to the Cypress PSOC parts. They are really neat with dedicated digital and analog blocks. You can set up up to 16 PWM (actually I use pseudo random bit sequences, which have less flicker) outputs, and the C compiler is really reliable vs the buggy stuff i’ve experienced w/ the pic (though the PSOC compiler generates crap code). The PSOC has it’s own shortcomings, such as a really inefficient CPU, but the digital and analog blocks more than make up for it b/c stuff is done in HW vs SW. PSOC is really fun, esp when u wrap your head around it’s way of doing things.",

Cesar: Geek Out Your Powerwheels

"Robots Hacks"
] |
[] |
[Zack Anderson] built
this
computer controlled autonomous robot (back in 2003) out of an old, ugly powerwheels Jeep. It’s got a full onboard computer with wifi, video camera, SONAR sensors, a robotic arm and it can self-navigate. He’s provided server and client code (I haven’t tried it yet), and The project shouldn’t be a surprise, since he’s been working on
entries
for the DARPA challenge for a while.

Modding Old Organ Bits Into A Guitar Amps
|
Will O'Brien

[
"Misc Hacks"
] |
[] |
[Forrest] sent in his Hammonator Organ that
he resurrected
into a guitar amp. He re-used several of the original parts, and designed the amplifier around them. Tubes were chosen to fit the sockets, and the original transformer was adapted to run on the 120V usually found today.

Wine Cellar Monitoring
|
Will O'Brien
|
[
"Uncategorized"
] |
[] |
I’ve been getting back into wine, and ran across
this
handy one wire wine cellar monitor. Aside from the usual iButton air temp sensor, they built a simple immersed
18S20
sensor to monitor liquid temperature as well. (I’d toss some sulfites in the water to prevent mold) To keep an eye on air conditions, they used a
TAI8540A
humidity probe. Looks like just the thing for the geek wine cellar.

Bowling, Industrial Robot Style

Will O'Brien

[
"Robots Hacks"
] |
[] |
If you like things like coil gun armed robosapiens, then you’ll thank [Aaron] for sharing his teams quest for the
ultimate in stupid robot tricks
. They hauled a 2800 pound industrial robot to the desert and used it to toss bowling balls… at an innocent RV. To top things off, they even lit one on fire. He even had to call the manufacturer up and sweet talk them into telling him how to speed up the robot so they could throw the balls even harder. The fire I can understand, but I’ve got no explanation for the roman gladiator or the bunny suit. Videos embedded after the break.

Bluetooth Headset For PSP/PS2

[Shane] put together
this
funky bluetooth headset hack so he could use his headset with both his PSP and his PS/2. It starts with a Cardo Bluetooth adapter. He added both a PSP headset style connector and a standard 2.5mm plug to a custom pigtail. Then he can use it with either a PSP headset remote or a modified USB PS/2 headset adapter.

UV Light Table

"Misc Hacks"

[Jared]’s
back in action
over at Inventgeek. Now he’s got an odd use for an old LCD: creating an ultraviolet light polarizing table. He gutted the LCD and swapped out the CCFL lams for some UV versions. The result isn’t much more than an interesting conversation piece, but it’s nice to see a use for screens that would otherwise end up in the recycle bin.

Looking at the panel won’t direct UV light into your eyes. Under ideal circumstances, you won’t be able to see any UV at all, and will just see the fluorescing objects on top of it. And if you do have a wider viewing angle panel – just check Wikipedia to clear up misinformation.While “black lights” do produce light in the UV range, their spectrum is confined to the longwave UVA region. UVA is considered the safest of the three spectrums of UV light. Unlike UVB and UVC which are responsible for the DNA damage that leads to skin cancer, black light is limited to lower energy, longer waves and does not cause sunburn. UVA is capable of causing damage to collagen fibers, so it does have the potential to accelerate skin aging, cause wrinkles and potentially destroy vitamin A in your skin.Source:http://en.wikipedia.org/wiki/UltravioletProvided you don’t stand over it for hours on end, all is well.",

[Dave] sent in
his
retro Mac project. Putting new guts into an old mac isn’t really unheard of, but I liked his solution to use the original Mac 512k keyboard and mouse. He used an Atmel AT90USB162 to create his own standard USB HID device. The keyboard and mouse appear as a standard USB device, so the mac (or any modern USB PC) can identify use the keyboard and mouse without any additional software.

this
nice little hack. The instructable says to get a USB keyboard (it looks like a Dell USB keyboard to me), gut it and label the flexible membranes inside after you join them together. If you’ve got a supply of this style of keyboard, it could be a cheap source… or better yet, maybe you can use the guts to produce high quality custom keybads.

HALO
, a nice diy high altitude recon project. Taking a page from the Kite Arial Photography guys, they mounted the camera on a servo tilt mechanism, had radio modem control and SMS gps position updates. I’m waiting for someone to put together a similar package that glides back to home base after the balloon is released.
By the way, if you’ve got a newer CRT RPTV, you might be interested how I
fixed mine

Embedding Apps In Wifi Finders

[Matt] sent in
this
excellent wifi finder reverse engineering project. The goal is to enable custom embedded apps that take advantage of the independent operating mode of the wireless adapter. One of the chips lacked any useful manufacturer markings, so he got some guys at a lab to etch the top of the chip off and get a partial chip id. So far he’s got boot-loader access, so now it’s just a matter of some development.

this
instructable showing how to make your own back-lighting for LCD displays. It’s a simple process, but I thought it deserved some attention given the cost difference for back-lit LCDs. It’s also a good exercise if you’re building your own projector and considering removing the polarizing film.

This isn’t quite a traditional Hackit, but I think you guys will dig it. Here’s the challenge: Given a budget of $600, put together the best hacking workbench you can. Don’t include computers or the actual bench in your budget. Oh, and you have to spend it all.
By the way, the best five submissions will get a chance to win a secret prize that I’ll be announcing around the end of next month.

My submission is the following:LCR/Multimeter, Ebay; 60$ shipped.(Mastech MS8222H recomended)The base of any electronics project, the ability to measure inductors and caps is priceless in any troubleshooting situation. the temp sensor and transistor checker is a bonus in the suggested model.________________________Oscilloscope, ~200$ used, Ebay.This is one of the hardest items to get whithin the given budget, but one of the most usefull. used for ANYTHING involving analog circuity._________________________Computer ATX Power supply conversion, 35$.Newegg P/N N82E16817103428120mm Fan, 11$ shipped.Newegg Item#:N82E16811998121By converting this standard computer switching power supply you get a relieable, cheap power supply which will give you a decent amount of power at 12v, 3.3v, and 5v. the extra 5 dollars tacked onto the price is to buy a few bannana posts, a switch, and a 10w resistor to make the conversion.the 120mm fan is to dissipate solder fumes. lead kills brains cells, ladies and gents._____________________Hand tools, soldering, etc:57-Piece Master Electronics Tool Kit 131$Jameco P/N 218245I took the lazy route. this kit seems pretty complete with all the pliers, screwdrivers, hex bits, and even comes with a hammer, for when you need to add a bit of manual ajustment.___________________________________security bit set, 12$Jameco#: 223829with these bits you can get into anything. service panels, elevators, vending machines, and others. these are like the lock picks of the appliance world._________________________Breadboard, 28$Jameco P/N \t20791jumper wire kit, 17$Jameco P/N \t19290a must for prototyping anything.also a jumper wire kit.___________________________5x 100′ rolls of solid wire, various gauges 33$It’s up to the user to pick what gauges they will need, what colors, etc._____________________________“Third hand” w/ magnifying glass. 9$Jameco P/N \t681002comes with a soldering iron holder, it’s the poor man’s version of the panavise, or for those who really don’t need to hold entire circuit boards that often._______________________________STATIC ELECTRICTY WRIST STRAP; 7$(can’t find the jameco p/n, all they have is disposables)probably the most important piece of equipment on the bench. hook this to ground, and you won’t static-kill any valuable ICs. be carefull while doing high power stuff though.__________________________Assorted Resistors, Caps, Inductors, ICs;1/4 watt resistor kit: Jameco P/N 10664, 25$1 bag 100 (x3) asorted mylar, ceramic, electrolytic caps, 18$.Jameco P/N 17857Jameco P/N 17881Jameco: p/N 17911never know when you might need something. this is just to get you started._____________________________________Additional hand tool:hacksaw+ blades 14$. usefull in many situations. I recommend the mini kind that have the blade sticking out. (ace.com Item no: 25898)Some people might say I ‘cheated’ by using ebay to get a decent price for the first two items.

(Most are combination scopes, too)Solder station-You never want to use a conventional soldering iron again after getting a high-power (>100W) temperature-regulated iron. Instant-on is wonderful. I paid 90$ for my Pace.A nice power supply-There’s several chinese outfits that sell 15V 10A, 30V 5A, 50V 3A, or 120V 1A adjustable power supplies at all roughly the same price (~$100). A voltage and current limited power supply is fantastic for doing any power systems work.JTAG programmer-You can build it for yourself pretty cheap, but it’s invaluable when you can find the JTAG test pads.A CPLD/FPGA devkit would be awesome too, although also likely the full $600 itself.",

"content": "I find a jewellers eye glass can be very helpful. Surgeons use them too. Basically a wareable magnifying glass.A simple cutting mat will help protect your desk.I also like to have some gloves for soldering. Aside from saving you from burns, they allow you to keep a finger on components while you solder them (normally they get too hot and burn you). Thus, you can keep them pinned to the PCB rather than having to try and work your way from the shortest components to the tallest, balancing the PCB etc.As for multimeters, ones with a clamp for measuring current are quite handy. Apart from just knowing how much power things are using, you can check that batteries are charging properly and that sort of thing.An RS232 to TTL level converter is always handy if you are using microcontrollers, and very cheap to make. You can go further by making your own “demo board” with LCD, LEDs and in-circuit programmer, for connection to breadboard.An FTD245RL board runs to about £5/$10, and gives you 8 programmable IO pins via USB. Better protected than the parallel port and handy if your PC doesn’t have one.An old PDA can be picked up almost for free (I paid £3 for an old Palm III with dock) and makes a handy terminal.A good lamp is essential too. Use bulbs that put out full spectrum white light, such as most energy saving bulbs or “daylight” bulbs (which are normally blue).You can get keychain digital cameras on eBay for £5, 1.3 megapixel and a reasonably good image. Perfect for documenting your project and keeping your main camera out of harms way.Finally, a clock with on-the-hour chimes to remind you to take regular breaks.",

While that’s a quick way to reach $600, it lacks the innovation that would make it a worthy hack.Instead, I focused on more obscure tools, and included a few that most hackers will not have, and may not even know that they want. A fun assortment of small hand tools and a couple larger tools.Here is my $580 plus tax:– Velleman VTBT11 100-PC Screwdriver Bit Set $9.95– Black & Decker LI3000 Cordless Screwdriver $40Security bits and a nice cordless driver to use them in, to open anything and everything.– Techni-Tool Tweezer Kit 758TW546 $95.25– Techni-Tool 00D Tweezers 758TW450 $26.71Excellent quality tweezers for precision work. Makes surface-mounting a lot easier, and no poor-quality tweezers can compare.– Xcelite Precision Driver 7pc 272SC019 $22.99Jeweler’s Screwdriver assortment by Techni-Tool.– Hemostats, half dozen assorted sizes, about $5 each, $30– Dental Picks (decent quality stainless) about $10 for the setGenerally useful implements for electronics. Hemostats, both straight and curved, are exceptionally useful for soldering through-hole components. Dental picks have a million and three uses.– 10x Watchmaker’s Loupe (Bausch & Lomb) with headband, $21Good magnification is essential. While this is no substitute for a $400 binocular microscope, it does help.– 5-Piece (approx) Stainless Steel Precision Pliers (needlenose, cutter, etc), about $20– Nibbler Tool $20– Tapered Reamer (2 sizes, $5 each) $10Various useful hand tools for holding things, cutting slots, and enlarging holes.– Small Bench Drill Press, $50– 29-pc HSS drill bit/index set, $25A hand drill just cannot compare to even a cheap drill press. Great for drilling panel holes, making starting holes for the nibbler tool, etc.– PanaVise Multi-Purpose Work Center, Model 350, $75Everyone needs a little vise in their life.– Harbor Freight 1 Ton Arbor Press, $32Good for all sorts of crimping and squashing and pressing. Also the cheap way to attach IDC ribbon connectors.– 24×36″ self-healing mat, $50– Xacto Standard Knife Set, $28The mat makes a great work surface, and it protects your bench while using the knives.– Quality Stainless Vernier Caliper, $15When accuracy counts, no ruler can compare to even a relatively inexpensive caliper.",

Jameco has a digital benchtop model that looks pretty good, it’s $166.total- $347Halfway there. Now, you’d probably need a power supply, so let’s check on those. There’s a fairly small but adequate digital power supply for $190.total- $535Sixty-five dollars to go.

In a pinch, it could be pulled from an old circuit board. Older model VCRs have lots of reusable through hole components.Bent up paperclips for improvised probes and jumpers.Power supply from a junked PC (found four last week at the curb).Breadboard. The $8 Radio Shack model mentioned earlier is fine.Spool of solid, four conductor phone wire purchased from surplus ($10 or less). Provides red, green, black, and red wires perfect for the breadboard.Baking soda and a piece of emory cloth for cleaning up all the corroded battery terminals found on junked electronics.Harbor Freight carries lots of handy, cheap tools, such as a soldering iron, screw driver set, security bits, and a $2 DMM. $20 goes a long way here.The most expensive piece of equipment I use regularly is the Atmel STK-500 ($79, but I think Arrow is having a promotion for $40). I could wire up a parallel port programmer and mount the AVR on a breadboard, but this is easier and I got it for free.Metcal makes really nice soldering irons, but I use a $5 no name model for nearly everything.Solder flux. I have an ancient container with a 59 cent price tag. It’s about the size of an Altoids tin and will probably be a lifetime supply. It’s a life saver when solder just won’t stick.The one tool I wish I had is a logic analyzer. Good for capturing serial data in addition to the traditional address/data bus.

"content": "@#20 – heat kills components. Ive found that being afraid of burns means you are burning more than yourself.On the rare occasion that I need to pin down a component with my fingers, that extra feedback tells me when hot is too hot. I wouldnt want to insulate myself from that.A better strategy is bending the leads on the solder side of the board. on ic chips, tack the 4 corners then work around in a spiral from outer pins to inner pins.worried about heat still? use a clip. but seriously… gloves are silly (its the “be a man and suck it up” moment of the post ;)Everyone mentions pan-vices and second hands and whatever. I have never needed anything like that. there are always strategies to hold a board. (I suppose I could claim a bit of manual dexterity as well…)As for the task at hand:$600 is a lot of cash for simple but useful tech bench. a bare minimum budget of a small breadboard (how often have you completely filled that massive 3 tier board?), a good iron set (iron, solder, desolder braid, a desolder pump is also usefull), and a selection of basic parts will get you where ever you want to go. Remember that the only bench that matters is in your head: Out there, away from your tools and your components and your O-scopes… what can you make happen?I’d add that most components are useless till you find a project for them, so generally it is better to buy as you need and scavange the rest. You’ll learn more that way anyhow.The only high dollar items I would recomend are a good multimeter (perhaps two, analog and digital. both have advantages and disadvantages and often complement each other). If possible, a scope is nice, but you might not turn it on much (depends on the type of projects you do).Id spend that cash on knowledge base: books, classes, etc.So, here’s my list (no values, you have all posted them several times)1 – soldering iron kit (30w)2 – breadboard small (strip your own wire from old cables esp cat5 plenum)3 – basic assortment of resistors, caps, pots, and switches4 – multimeter5 – brain training.. A good reference bookshelf is worth more than any piece of equipment ever will be.6 – take a class. Various manufactures of hardware/software offer (often free) classes. For example: National Instruments. This is especially true of automation hardware manufacturers. Also, check out demo software of usefull applications. Give Mathlab a spin. Try out Electronics Workbench. Play with Eagle. Download all of the free versions of MS Dev studio (if you work on that flavor of o.s.). Enjoy the free-ness of linux and the latest round of electronics software.7 – (the most important) Spend the bulk of your cash starting a group in your area or contributing to an existing one in the area, such a Robotics group, a maker group, or a PC hacker group.I dont see the sense in blowing a wad of cash then staring at your bench with all its new toys and parts and asking yourself “well… what the f$!k do I do now?”",

I picked up a Weller WESD51 for around $140, and it’s worth it.My Weller iron heats up quickly, maintains a regulated temperature, and the tip doesn’t get eaten by solder. My Radio Shack iron heated up slowly, but then got too hot. I had to replace the tips fairly frequently because they were eaten away by rosin fumes.I still have the old Radio Shack iron, but I mostly use it for burning holes in stuff that I don’t want to get on my good iron.",

"content": "I am going to have to agree with comments 42 AND 43.Newer kit based oscopes are way better than a $250 used 100mhz tektronix. – that is unless you are a mindless MHZ junkie. (when are you going to look at crap over 20mhz let alone 200mhz?) Get a pc based scope – recording the wave IMO is much more useful than looking at it.Another opinion I have is that a high quality soldering iron is *CRITICAL* to good soldering – I am an old 2M tech from the navy and we had crap irons and good ones so I have done my time with both. Good soldering irons heat up almost instantly (-5secs for my ebay PACE), they don’t erode in front of your eyes, they have a huge assortment of tips, and most important – you can get tweezer irons and hot air pencils for most good quality iron bases. Hot tweezers will pay for themselves in one component harvesting session as will the hot air pencil. I prefer PACE irons over Weller, but this treads near a holy argument (and I’ll leave it at that).So here’s my list:PC Based Oscilloscope, Velleman Kit K8031 $150.00Probes: Ebay Seller: MDFLY or others $20.00/pair10-30x stereo microscope:Ebay Seller: Precision_world or Microscope_Universe200.00 with boom arm, light and USB camera.temperature controlled soldering iron:Pace SODRTEK – once in a while you get non ROHS compliant (just missing the lead free label) TW50 Irons, with PS90 pencils on ebay for less than $100 but in general you are probably going to spend about 100 for a TW50 base and another 50 on a pencil, 50 on a tweezer set and $10/tip (they last MUCH longer than radio shack 1.99 specials).This is close to 600. If you get some more cash,I would also invest in healing mats, various dremel tools, good solder/flux, TSOP readers and various programmers (PIC etc), some of those organizer bins from walmart or tackle boxes and a healthy amount of beer.",

"content": "First post was error filled and probably blocked due to reference URLs… so here goes number 2.Well, I suppose the key word here is “hacking” workbench. Which means we’re coming at it from the hacker mentality.Hackers are champions of the bizarre, and their goal is always originality through ingenuity. A workbench that supports this goal would no doubt embrace this fundamental ideal.As such I submit to you, my view of the “hacker’s workbench”.$3.48 – Duct TapeDuct Tape represents a bare essential that must be available to everyone from house wives to wiley eyed hackers. It’s uses infinite and it’s contributions to society legendary.$25.18 – Bottle of Everclear190proof liquor. This is an important medical aid in the event you injure yourself. Capable of acting both as an anesthetic as well as a sterilizing agent. In the event you accidentally stab yourself in the leg with a live soldering iron, you’ll be glad to have this on hand to treat your leg as well as yourself. Has many additional uses.$5.49 – Hack SawIt has hack in the name. And it’s purposes are many. From cutting pvc for building out your vegetable projectile arsenal to getting the cuffs off after a particularly awe inspiring hack… this little hardware charmer represents the heart and soul of hacking and is thusly named.$16.23 – Klein Tools 10 in 1 Screw DriverKlein is a well known brand of tools favored heavily by angry local 103 journeymen and home depot addicts. Their 10 in 1 screw driver represents the single most ambidextorous screw driver in existence. It also is a great chew toy for mans best friend. I’d also like to recommend the Klein tools beer bottle opener… for when you just need that extra bit of liquid courage before you close that loop.$5.99 – Rubber MalletThe almost mystical capabilities of the electronic diviners mallet is a matter of folklore often passed by word of mouth down through the generations from master to apprentice. Many a friends friend has solved the impossible problem through the application of this tool. The rubber mallet, first in self defense and last in ditch efforts to fix the unfixable. This tool is the Global Thermonuclear War of hacking. Would you like to play a game?$7.39 – Box CutterThis weapon of mass destruction is responsible for the deaths of nearly 3000 innocent people on Sept 11 2001. While we may remember this incident as a tragedy it will stand as a testament to the capacity for destruction that this tool can achieve when handled improperly. When attempting to use this tool on something other than boxes, please exercise EXTREME CAUTION.$2.15 – Spray BottleThe spray bottle. It’s not what’s inside that counts… it’s what you spray it on. From acids to bases this bottle can store your chemicals and distribute them in a spread pattern allowing for an even application of fine mist. Additionally great for cleaning the ole workbench off after you’ve dipped into the everclear one too many times.$33.39 – Vice ClampFor those of us lacking in a hefty oompa loompa population willing to imperil their hands… a vice clamp is a true ally. Because lets be honest… you certainly wouldn’t want to be holding your project with what you are about to do to it.$49.35 – Cheapish Solder StationYes, a true hacker could solder using a coat hanger and an open flame… but let’s be honest… a true hacker has used all of their wire coat hangers already on other projects and break in attempts. And bumming solder/wick is a social don’t.$79.97 – Spool of Cat 5e (Yellow)Category 5e Ethernet Cable. This is the defining copper wire for any hacker…. it’s uses are limiteless. From networking your pcs at near gigabit… to holding your pants up… to jumping your solderless breadboard… this wire knows no failure. I wouldn’t try bungie jumping with it though… you put kinks in it.$40.73 – Multipurpose RespiratorAside from generally looking awesome, these guys will protect your lungs from a lot of the nasty stuff that you put into projects (or pull out of them… as the case may be). There’s also the added benefit of using the left over money from your rodney king beating settlement after the police beat you within an inch of your life for bringing one on the train with you.$13.95 – Polymer Lithium Ion BatteryAll engineers, hackers, and do gooders alike share one common principal. Never be without a power source. The current battery of choice for the hack minded are the 2000mah polymer lithium ions and others of that family. No work bench should be without a reserve supply. And no hacker should ever be caught without a power source.$14.65 – Toaster OvenFood yes, SMD soldering Hell yes. Sure your muffins might taste like mercury but the buzz is killer.$5.00 – MultimeterIt will tell you what the voltage, and current are. Then you will be able to figure the rest out on your own. Also makes a great paper weight.$30.35 – Hair DryerSure it warms your hair up. Dries your hands off. It also will dry your projects up, and melt some polymers. Additional points if you can incorporate it into a project.$13.79 – Fire ExtinguisherFire, mans greatest conquest, and a threat to your porn collection should a work bench project ever go drastically wrong and result in combustion. It would be wise to have a fire suppressent available to you in the unlikely event of an open flame appearing where unexpected and unwelcomed.$10.95 – Stylish Safety GogglesIt’s hard to hack when you are blind. And while eye patches help on talk like a pirate day, a lack of depth perception could be the difference between you and a you with a soldering iron stuck in you. Wear the goggles, be able to enjoy your porn for just that much longer.$21.00 – Mechanix GlovesSometimes you have to crack open an unfriendly device. Razor sharp casing, Shredded metal edges, Hot components. Protect your hands. Don’t leave fingerprints. And the hair folical the police are showing you is probably fake.$129.95 – Variable Voltage Power SupplyDevelopement is considerably less awkward when you aren’t redesigning the power supply on your board every time you upgrade the functionality of your toaster.$69.99 – USB O-ScopeWhile most hackers use ancient o-scopes they found at auction or swap meets, or simply plucked from a grumman du,mpster… Some folks go retail and buy themselves a nice cheap USB / serial software oscope. The oscope is the quinessential reverse engineering tool…. anyone who has seen sneakers knows the awesome power of a blind person, an oscope, and an answering machine that decrypts telnet.$22.02 – Pry BarSometimes hacking means, actually hacking. The thing is… most manufacturers don’t want you disecting their product… be it for harvesting black market components or simply to add it to your artoo unit. Prybars when coupled with your rubber mallet can make short work of even the most obstinant of materials. It also makes a great self defense weapon when that junk yard guard dog gets the drop on you.",

The wiring job looks excellent – very clean and well done. The only thing missing is a touchscreen.

USB Transferer (AKA USB Gameboy Card Interface)
|
Will O'Brien
|
[
"Nintendo Game Boy Hacks",
"Nintendo Hacks"
] |
[] |
[Jose] sent in his efforts to build his
USB Transferer
. I’m pretty sure it’s a gameboy flash cartridge interface based on the Atmel AT90USB647 AVR microcontroller. Once the prototype board came in, he soldered the controller, gutted an old gameboy for the cartridge connector and had the device showing up on his PC by the end of the day. Oddly, the card he’s interfacing with is a USB device on it’s own. Until a few more details are published, I’d assume that the interface would be useful for connecting to more than just that particular card.

It’s the same principle as the taser gun; a lot of tension but very very few current passing through the body resulting in a stun/paralyse state instead of death. Current kills, voltage sort of paralyse (to be simpler because on a medical term I don’t think it’s imsple as that).I’d really like to see proof that this thing actually kill.",

Great Intro To Surface Mount Soldering

[Scott] sent in his video how-to on
surface mount soldering
. The macro video quality is excellent, and the demo is great even if you’re already into SMD work. Everything can be done with fine solder, a decent soldering station, tweezers, a 10x loupe and a good selection of flux. I’ve managed quite a bit of SMD work without external flux, but this sort of demo shows just how effective it is.

this
video (scroll down) showing how to make a vacuum tube by hand. The page and captions are in french, but it’s pretty interesting to watch. A small spot welder, some fairly basic glass working tools and a vacuum generator are required, but the technology is definitely within reach for the dedicated hardware hacker.

"content": "This is some seriously beautiful work.I second the notion to create Nixie tubes using this!As someone who was actually PLANNING to build a giantNixie by hand myself, I wonder if he used any mercury in these (didn’t see any). In Nixies, a very small amount of mercury was often used along with argon/neon inside, and varying the noble gas along with the amount of mercury changed the intensity of the orange. Look up Penning mixtures on wikipedia.What metals did he use? I’ve been planning my Uber Nixie to use tantalum wire for ultimate cathode & annode life, but that is a bit overkill…Lastly, I’d be curious to see the working life for his tubes. The hardest thing to control making a vacuum tube is the metal to glass seal- depending on the type of glass and ESPECIALLY your choice of metal, a good seal can be hard to achieve. Many Nixies have gone bad due to their seal. He’s annealing the glass, I think, in that cannister between steps to reduce strain in the glass (tempering it), and to alieviate compression stress from the heated metal shrinking at a different rate than the glass. Understand, if you just melt glass around a metal wire, it will not make a perfect seal unless you anneal the glass (otherwise it will crack)This guy makes it look EASY- there is a LOT of small bits you have to know about both glassblowing, metalurgy, and glass-to-metal contraction properties to do something like this properly (researched forever for my Nixie). He has the right equipment and serious skills.FOR OTHERS wanting to try this- if you get good with glassblowing, you can try this yourself, provided you have a vacuum pump and, for Nixies, a glass cylinder of a noble gas (less than 100$)- just do some research here:http://www.pmillett.com/tecnical_books_online.htmThis guy has a lot of books on tubes- many are quite good, and they are all FREE. I learned everything I have from reading all of these, some of which are original company manuals for production!Hope this helps. REMEMBER- most of the basic fab is not too difficult with a lot of glassblowing experience, it’s the GLASS TO METAL SEALS you need to worry about.",

Basically, you just get a power supply capable of putting out some amps, and hook up a thick enough wire to it (you could probably pilfer it from a toaster — I think we used piano wire). Wrap the wire around the glass (making sure not to have the two ends touch, which would short circuit your short circuit!) and hit the power. The glass cracks due to thermal expansion. If needed, you can squirt some liquid (like alcohol) around the joint, which will cool off the glass quickly, causing it to break.",

I’ve been trying to find an excuse to pick up one of the HD Aiptek cams for a while now. [windowlikker]
posted
his simple pre-amp + external audio input mod for his Aiptek AHD videocam. Unfortunately, the mod is limited to mono input unless there’s an un-used stereo input on the encoder board.

Nixie Counter Clock

[lerneaen hydra] sent in
his version
of the ubiquitous nixie clock. Rather than gut his counter for the tubes, he used an Atmel Mega88 to pulse the clock to display the time. Additionally, the LED matrix on the case outputs the time in binary. His past projects are worth checking out. He milled the case on his converted
CNC mill
, retrofitted an old
CNC lathe
and seems to enjoy putting supercaps in
everything
(including his clock).

Drew Endy

Programming DNA
talk was by far the most interesting talk we saw at
Chaos Communication Congress
. No, DNA doesn’t have much to do with computers, but he points out that hacking principles can be applied just the same. Right now engineers are reversing genetic code and compiling building blocks for creating completely arbitrary organisms. This talk was designed to bootstrap the hacking community so that we can start using and contributing standard biological parts to an open source collection of genetic functions.
You should definitely
watch the video
to get a good idea of where biohacking is at today. You can find a higher quality version of the video
in the archives

Secondly we as a species have already done this with things like the introduction of antibiotics, their widespread use is theorized as the reason for new AB resistant bacterial strains.My biggest reason for not being worried is because of the people who already do this sort of research. There’s a professor(I believe of some type of bio science[it’s been a while since I read this article]) at UT@Austin, who is a proponent of wiping out the human race to restore the earth to a “natural” state.

SDI Mod Your DVD Player
|
Will O'Brien

[
"home entertainment hacks"

[] |
I’m not usually into products, but I like this one. Remember
this
diy SDI DVD video out mod which lets you send high quality digital video over coax? Thanks to
Pixel Magic
, you can mod
a variety
of DVD players to add SDI thanks to the kit they’re offering. At a glance, bt.656 and bt.601 appear pretty similar, but the eval kit from the original only claims to be compatible with bt.601 while the Pixel Magic version is for bt.656.

PSP Internal Hard Drive Mod

[
"Playstation Hacks",
"Portable Video Hacks"

[] |
[Robin] over at acidmods sent in
this
interesting PSP mod. [PvP] added an internal hard drive (with the exception of a mini-usb cable sticking out the top) to his PSP. The advantage? Laptop hard drives are dirt cheap while sony memory sticks are still pretty pricy. More details should be along soon, but [Robin] assures me that this means up to 200GB of storage is possible for the PSP.

That’s supposedly not possible without USB OTG.Either he’s using Wifi to browse a PC running usbhoststfs and pretending it’s actually an ‘internal HDD’, or I’m misunderstanding the claim being made.That said, the Datel 4Gb drive supposedly uses a special CF>MSDUO adaptor board and a CF microdrive. Since IDE and CF are pin-compatible, why can’t we just hook up a similar adaptor (IDE > CF > MSDUO) and supply an external power pack for the drive?Would there be file system limitations?Hmm, you can pick those things up for about £40 now.

I have tried connecting my 160GB WD Passport drive (it is powered through USB) and guess what…nothing happens. The PSP can use the USB as an expansion port for peripherals, but it can’t (to the best of my knowledge) put out the power the run my pocket sized wd passport.Unless this guy is powering his drive, and i don’t think it would matter if it was SSD or HDD, then it should drain the power on the PSP in about 20 minutes(or something).Why it won’t work…the picture…come on’The power…it would eat the 2600mh battery alivethe software…its simply not capablethe psp itself…even if you gutted the UMD drive and a few other components, it would still be like the to stuff Oprah into Anne Heche.i keep coming back to this page to see if it has been demystified…but until someone puts out i am sticking to my first response that this is garbage.",

The same chip used by car stereos to read USB pen drives could be used with the PSP by modifying the software that lets you use data from a PC (USBHostFS? IRShell?) to communicate with this chip instead. Official peripherals that plug into the USB port on top are not USB, they communicate via serial, so using that port makes sense now.",

None the less this is a great and probably the most practical mod. (all casings and housings must be removed from both the female usb and all attachments such as the flash stick.)",

You can’t just take a Ipod HDD (or similar) And wire it up to the USB port of the PSP.The PSP does not interface through it’s USB port the way some are thinking, It use’s 2 Type’s (A and B) A for USB Mass storage which your PC reads, and B to send data in to the PC and out of the PSP.The PSP Does not Support USB-HOST as you guys think (and as some have already explained)IRShell only reads USBHostFs if it’s being run on a PC, Unless you made an advanced micro controller to run the USBHostFS like a PC and wired the Ipod HDD to that micro controller (let alone actually having it read as a usb mass storage device) You’d also have to wire the PSP to the microcontroller.That’s the only way possible, and to top that all off. You couldn’t use the hardware anyways as the PSP by default use’s Type-A in USB mode to read data so you couldn’t even read the info thats on the HDD let alone transfer it?It’s a hoax. The PSP’s Firmware can only do so much, Especially when it comes to adding on hardware.",

Got Spam? Let Us Know

I’ve been getting a few sporadic reports of SPAM that’s supposedly from hackaday.com on it. It’s a bit surprising, considering that the only email we send out automatically consists of comment confirmation requests to prevent comment SPAM.
So do me a favor… if you’ve gotten any, send it along with the email headers so I can track down the source and
destroy
er make it stop.

Inexpensive MPG Modding

[basjoos]
modded
[
via
] the body of his ’92 Honda Civic – and managed to improve his fuel efficiency from 50-60MPG up to 95MPG for about $400. Even more interesting is the
SuperMID
(
Translated
) that he added to the car to monitor his fuel efficiency. It’s based on an ATMega8 that reads the CAN bus and displays realtime MPG information an a character LCD. The SuperMID is popular for Prius modders because the on-board display maxes out at a paultry 99MPG. If micro-controller’s aren’t your thing, [Atilla] put together
his own
CAN bus decoder and ported his code to a Zaurus SL-C700. He even added voice feedback notification for certain data events.

But as long as his measurement methods are consistent, it’s still a 53% improvement no matter what the actual numbers are.2-3 mpg for the headlights suggests the headlight load is around 2% of his engine output. That sounds high; he’d have to be cruising on only 5 horsepower or so. Later I think I’ll run the numbers and see if I can approximate how much horsepower he’s actually consuming…",

We know that the air resistance can be accurately approximated as:AR = -A*v^bwhere A and b are related to the car geometry (fixed)and air viscosity (also fixed)Then his MPG should decrease greatly as speed increases and continue to reduce more and more as speed increases, so his numbers a baloney.You also do not want a tear drop shaped rear end, you want a VERY steep drop on the back, straight down would be ideal as this will decrease the drag due to the air moving along the increased surface of the car since you are tripping into turbulent flow at the back end. This is the same reasoning that caused mythbusters to show that you are better off leaving your tailgate up, not down, as you’ll have less resistance.There is also no mention of the added weight of all of this paneling, which is not weight free. He may as well left the whole thing alone and spent money regearing the transmission to some ridiculously high gearing, concentrate on covering/eliminating any holes in the front of the car (bumper/gaps around any lights), and finally make the back of the car more sheer than long and drawn out like that.. . . and it’s really ugly",

People with money who buy cars don’t really care about mileage as apposed to style or image. Also this car has 92 HP stock with 97 fp of torque which is the highest power of the top ten gas mileage cars of all time so it moves. Weight to power ratio is great in this car stock.",

The addition of at most 150 lbs is not going to decrease fuel efficiency by much, however if that 150 lbs goes towards lowering drag coefficient from something like .30 to .15 you are going to see some serious improvements in efficiency.This kind of modding is not new, but as pointed out by some of the other less mature commenters it can mess with the aesthetics of the car, so you don’t see many production vehicles incorporating these elements. I agree that much of his work looks far less than professional, but from what I gather from the forum topic it’s a work in progress and most of the fairings etc are just prototypes to test performance.To see what you get if you design a car around aerodynamics check out the Aptera Type-1. A production level hybrid car offered by Aptera that gets 300 mpg, costs 30,000 (they started taking deposits in September)",

Most cars have a Cd of around .3 or so. Reducing this to .15-.18 with mods is relatively simple. Cars designed around reducing Cd can reach as low as around .07. It’s nothing new.To the people suggesting mods to the electrical systems/alternator yes that can help some, but you won’t see nearly the increase in efficiency as you would from aero-mods, low rolling resistance tires, and supermiling driving techniques.

Rotomolding
is used to create hollow forms by slowing rotating a mold while the material covers and hardens to the shape of the mold. [ds] built
this
version using a stepper motor to drive the assembly and a belt drive link An extreme version is used to form whitewater kayaks and other plastics.
This
thread over at cnczone has a rotisserie oven version that looks ideal for small plastic or wax molding.

24C3 Mifare Crypto1 RFID Completely Broken

Another highlight for us at CCC was [Karsten Nohl] and [Henryk Plötz] presenting how they reversed Philips crypto-1 “classic” Mifare RFID chips which are used in car keys, among other things. They analyzed both the silicon and the actual handshaking over RF. Looking at the silicon they found about 10K gates. Analyzing with Matlab turned up 70 unique functions. Then they started looking “crypto-like” parts: long strings of flip-flops used for registers, XORs, things near the edge that were heavily interconnected. Only 10% of the gates ended up being crypto. They now know the crypto algorithm based on this analysis and will be releasing later in the year.
The random number generator ended up being only 16-bit. It generates this number based on how long since the card has been powered up. They controlled the reader (an
OpenPCD
) which lets them generate the same “random” seed number over and over again. This was actually happening on accident before they discovered the flaw.
One more broken security-through-obscurity system to add to the list. For more fun,
watch the video
of the presentation.

So neither will work in the future. This is not economical for hackers to do (nor is it for the owner of the original card). So, as always in security systems, you have to look at the entire system for a proper security assessment. In transport it makes much more (economical) sense to place most of the security in the back office and only use cheap cards with relatively little security on them in the field. Otherwise we would all be paying more for each subway ride, and who wants that? :-)",

"content": "@Karsten: The legal side of your case is starting to intrigue me. In your presentation you clearly stated that your findings on the Mifare Classic chip mean that the Philips car key chips are not secure any longer and that people should start migrating. This is a wrong statement. (It does not matter whether those car key chips are weak too or not.) Now, should Philips find that the sales of their car key chips are declining in the wake of the current media attention – something that is not unlikely to happen – then they will come back to you and sue you for compensation. Given that this is a multi-million dollar business for them, they are likely to sue you for many millions of dollars. And since you have named your University as affiliation in your presentation, it can be sued as well now, and that would be the US, where big money can be sued for. All this may take many years, but I am afraid that Philips will win. This is a clear-cut case. You gave them all the arguments they need on a silver plate. So you should consider your next steps rather carefully. Well, you have my sympathy.",

There are many applications where you donât need such a high level of accuracy. Of course, for banking cards or for the new smart passports these ten years old chips are not applicable and youâll have to spend more money to buy some of the latest generation smart cards – security has its price.I donât underestimate the work presented here. I just say that breaking such an old chip it is not a big breakthrough and the effort is not paid back.

Goodbye 1167627600 –
1199167140
1199163540.
[Justin] is having fun telling everyone that
an exploit
has been found for the Archos 605 media player. The hack gets you remote root access on the player… need I say more?
[Gene] sent in his
polar coordinate based
LEGO 3d printer. He’s still working on the driver end, but it’s an interesting project.
[Kyle] sent in
the gutting
of his flip video camera.
Need some new storage? [forrest] sent in his price/GB
price comparison script
. It scrapes New Egg and graphs out the results.
Despite the link on our
old post
being dead, [Txoof] built
his own
CCFL macro light from a dead laptop LCD.
[Dan] sent in his
LED cube matrix
. The LEDs are wired in a matrix, so he can actually address them individually.

Frostbot: CNC Cookie Frosting
|
Will O'Brien
|
[
"cnc hacks",
"Misc Hacks",
"Tool Hacks"
] |
[] |
[Brian Schmalz] sent in his
Frostbot
. It’s a fun CNC bot project that he built to frost cookies for his latest holiday party. He (wussed out a bit) and started with a
kit based
CNC machine, but he made up for it by driving it with his own control hardware (that
sparkfun
happens to have for sale). His USB
bit wacker
interface certainly looks interesting – I might consider adding it in front of the stepper
controllers
on my
cnc mill
. Especially interesting is the HPGL interpreter software that converts graphics to stepper commands via the bit whacker interface.

24C3 Toying With Barcodes
|
Eliot
|
[
"Laser Hacks"
] |
[
"24c3",
"barcode",
"ccc",
"scanner"
] |
[FX] from
Phenoelit
gave an entertaining talk about barcode security. He covered both how the systems are implemented and how they’ve been exploited. The first example was a parking garage in Dresden that issues non unique barcodes for the unlimited passes that hotels give out. Anyone code print out an image of that particular code and park for free. German grocery stores have automated machines that refund you for your empty beer bottles. The barcode generated just states the refund amount (5 digits) that you’ll get at the register. Just stick the barcode under something like a six pack and it’ll scan even without the cashier seeing it.
Check out the video
to find out more silliness involving DVD rentals, boarding passes, asset management, and SQL injection via the scanner. You can even find higher res versions in the
24C3 media archives
.

If you were going for individual item detection, they’d have to use something with a form of rf or magnetic data storage- either way you’d either be bombarded with rf from every item while in the store or have to pass through a bigass cardreader (which opens up a whooole new slew of security issues).

[Motoma] sent in
his take
on the
virtual RAID 5 post
. He didn’t like the layered system requirements, so he put together a proof of concept that only requires a Linux box. For his proof, he used a NFS share, a SMB share and did everything from the command line. He didn’t cover FTP, but the Gentoo wiki has a nice
cheat sheet
for mounting FTP and folders over SSH if you want some alternatives. He uses some very interesting partition tricks to make things happen. If you need some help to get things rolling, the Ubuntu forums
software raid how-to
is a good place to start.

If you really wanted to put a partition on the raid, do so on the MD device, not on the individual files.A word of caution, loop devices will not be aware if the underlying file becomes unavailable. Loop will not tell the raid that a device has disappeared, so be prepared to have to resync often and possibly lose all of the data contained.",

DIY Wakeboarding Winch

[exhaltingidiotz] is just
one
of the guys who’s built his own wakeboard winch. These things are pretty low tech, but using a winch to wakeboard has to be one of the most original ideas that I’ve seen in a while. Winches have some interesting advantages over boats: less fuel, no licensing and shallow water that no boat or jet ski would ever work in suddenly becomes usable. Here’s a
basic
design that’s typical and a simple demo
video
. The forums are a bit annoying to search for info, so here’s a
fantastic
winch build writeup.

"content": "Sailplane pilots use huge versions of these to snatch gliders into the air. This is especially common in Europe where fuel is expensive. The basic principle is much like running with a kite. With a few thousand feet of open space to pull the cable out over, they can get altitudes of over 1000 feet. It’s quite an experience; the ground roll is maybe a hundred feet, and most of the climb is done at about a 45 degree angle! This photo will give you a bit of an idea what it looks like; the winch is out of sight over the rise in the background.http://www.gull.us/photos/misc/winchlaunch.jpgGlider winches are sometimes based off of truck drivetrains — basically a big engine, transmission (generally set up to stay in 2nd gear for the whole run, to avoid any jolts from shifting), and differential, with the winch drums replacing the wheels. A similar conversion based on a moped might make a good wakeboard winch, with a lot less fabbing involved than building the whole thing from scratch.",

Probably the most significant platform for promoting winching is the rail jam. In the past wakeboarding events had to get people to the event on a lake; now rail jams bring the event to the people. Rail jams are being setup in bar parking lots, and other general locations outside of the lake areas. Last summer the Texas INT had a 6 stop Rail Jam Tour that attracted some big wakeboarding names, and was sponsored by Nissan of North America; thats right, corporate Nissan not some local dealership. Who’s going to push winching? corporate america. Winching is a big marketing platform that will catch on in the corporate marketing world. Hell, wakeboarding was the fastest growing sport in America in 2006. Any pro rider that is limiting themselves to just boat comps will be missing out on the big purses that rail jams will bring. Why? because there are more eyes to watch at a rail jam than at a wakeboard event on a lake. Eventually rail jams will be the preferred pro rider event.[img]http://www.bulletlines.com/images/newwinches1.jpg%5B/img]Thanks,Ken LandBullet Lines",

[Dane]
built
this excellent home theater pre-amplifier. He used [Mark Hennesy]’s
pre-amp design
to start with, and added selectable XLR, RCA, SPDIF and even USB audio inputs. Discrete inputs from his DVD player provide surround input, and an analog matrix creates 7.1 surround from the 5.1 input. The design is very elegant, and even uses a VFD display that appears blue with some filters. I usually just buy my HT gear, but projects like this make me seriously consider re-building my entire HT from scratch.

The 24th annual
Chaos Communications Congress
in Berlin is already off to a great start. The first talk we attended was [Antoine Drouin] and [Martin Müller] presenting
Paparazzi – The Free Autopilot
. Paparazzi is an open source hardware and software project for building autonomous unmanned aerial vehicles. The main hardware board has an ARM processor and GPS. It uses inertial and infrared sensors to determine orientation and altitude. The four infrared thermopiles measure the air temperature. The ground is warmer than the sky and if you compare the temperature in the direction of each wing tip your can tell what angle the airplane is at. It’s really that simple.
They did a pretty amazing live demo. Using the network connection they controlled a UAV flying in France and another in Germany. Both planes were streaming live video from belly mounted cameras. One relaying through a home DSL connection and the other through a UMTS cellphone. They were able to change way-points on the fly and issue flight pattern commands. There is a ground crew at each location with a security pilot that will switch the controls to manual if things get out of hand.

The arduino is really starting to become prevalent for hardware hacking. [Nash] used one to take control of his Gaggia espresso machine. (They’re really decent little machines) He popped in a LCD display, some solid state relays to control the pump and the heating element, and an
AD595
to interface a K type
thermocouple
. It looks like an excellent hack, but for the love of god man – get a better grinder!
He describes the original mod
here
, and added a small gallery of internal shots
here
. From the latest comments, it looks like the guys are
RepRap project
are even interested in the thermocouple PID control that [Nash] implemented.

Holiday Hackit: Automated Hard Drive Destruction

One of our
recent
posts took an interesting tangent: physical hard drive destruction. First, [wolf] wanted to use a 20ga shotgun shell on his hard drive. [brk] suggests an electromagnet applied to the drive while it’s still spinning. Everyone thought
thermite
might be interesting… Finally, [wolf] noted
this
commercial auto destruction drive that floods itself with an acid mist. I’ll suggest a few ideas and let you guys take it from there.
I’d suggest pneumatic injection of two part epoxy into the drive mechanism. Remove the top of the casing using the
diy clean room
method, add a port for the epoxy and use a cheap CO2 bike injector to force the liquid into the drive on demand.
So, got a better idea? Let’s hear it.

But not enough to burn through the rest of the drive and case.Once nice thing about thermite is its cheap and commonly available.http://cgi.ebay.com/Thermite-100-grams-Fe2O3_W0QQitemZ230206230007QQihZ013QQcategoryZ1267QQssPageNameZWDVWQQrdZ1QQcmdZViewItemYou could light it either with a magnesium powder starter, or by mixing it with potasium permanganate (definitely misspelled) then adding glycerin, which will react with the potassium permanganate and spontaneously combust at high temperature, setting off the thermite.If I have some time once my college apps are done, I may put together a video testing this out.Also, about frying the drive with a battery, all that would be fried is the controller hardware, so the data could be recovered by replacing the controller or moving the platters to a new drive.",

You may be able to use one of the ‘covered’ vent holes (the ones that say ‘removal voids warranty’)3. Usually a good physical impact of the drive (flat side) against a hard floor (ie. concrete) will provide enough force to render the drive un-readable (by conventional means). I’ve even heard of some drive platters shattering under this type of impact. (could probably build a machine to do this)4. Place desired drive to be ‘destructed’ into a fire.. (outdoors and/or well ventilated) eventually the Al should melt (if hot enough) and the platters de-magnetize..5. (this one’s not so simple, but it would be awesome) Perfom specialized high-impact projectile testing and record high-speed images. (why?

After a quick check it seems commercial variants that are NSA / DoD approved so they must be relatively effective against modern recovery techniques. The most effective version of this would be one where the coil had a letterbox shaped slot in the centre for the hard drive.If hard drive companies wanted to introduce ‘self destructing’ hard drives they could simply design a physical kill switch on the controller board. When this is set to ‘destroy’ and power is applied, it automatically starts writing random data over the platters. The distinguishing feature of this process could be that the power applied to the coil on the heads would be much greater than usual – as much as they could dissipate continuously.It is unlikely epoxy would be an effective deterrant – most epoxy resins can be softened / dissolved.",

Burning or melting is a lot harder to reverse.Something else you could do is get a thin metal beam with teeth, then lower it ont the platter so it shreds it. As long as your data wasn’t *too* valuable, that’d deter everyone except the NSA.",

For CD and DVD I use a shredder designed to handle optical media.A pleasant surprise was that it is rarely necessary to cut all the way through the drive, or even half way. When setting the blade to cut slightly off center of the axis the platters usually shatter and only a cut of about an inch is needed.So, for less than $300 one can get all the hardware needed for media ‘sanitizing’.",

Red Wine audio offers the
iMod
– a service that modifies the DAC in 4th, 5th and 5.5th generation iPods. Despite requiring some fine work, the mod isn’t that difficult. [joneeboi] sent in his DIY DAC mod how-to, and even better, it’s suitable for 3rd gen and 1st gen Nanos. The audio signal is tapped directly after the DAC, and the SMD capacitors in the iPod are replaced with high end Black Gate capacitors. This is just the mod feed the best possible signal to your headphone amp

Power conditioners are very nice, expecially in areas where the current is rather irregular (*cough* lights dimming because the sub amp is drawing so many amps) or outlying areas like camps where the power lines may be old or overdrawn.For anyone that has listened to an ipod beside a good DAC know that there is a very large room for improvement. The first time I got my nano I had to get used to the “harshness” of the signal, which gets progressively worst above the 70% mark in the volume control. Some of that is probably do to the preamp not getting enough juice and outputting “square waves” which are incredibly harsh (on the ear and speaker) due to the added harmonics.",

"content": "From all the pin-outs I have seen there doesn’t appear to be an SPDIF output on the iPod.Apple seems very keen to stop you using the iPod as a means for you to transfer music to your mates. Putting an SPDIF output on would mean your mate could sample the audio and get a perfect copy from your iPod. I reckon if you dig lightly you will find some legal artist protection clause Apple has relating to this. Sure, you could record the iPods analogue output but that’s not a perfect copy and thus satisfies the legal bit.Hence you need to physically (and without Apples authorisation I may add) modify the iPod to get any kind of SPDIF output (as Wadia do- read on).regarding the DAC itself it’s (likely) to be a MP3 to dual channel analogue converter- I would think it highly unlikely that Apple would use two chips; one to convert from the raw data taken from the Hard Disk to SPDIF then another to convert SPIDF to analogue when they could get a DSP to do the whole thing.i.e. economy of scale- as they make millions of iPods there’s probably a custom IC they had made which goes in all iPods and though cost millions to develop works out cheaper in the long run They may even use the same chip to do the audio and video. Why not- if it can do a couple of MHz for video then audio’s just slower. Best of all its cheap and as we know it sounds crap anyway!Indeed in the future there will probably just be one large ASIC that handles everything from HD control to the LCD, backlight LED’s and cap-sense wheel. Oh and that would blow all your chances of tapping into a SPDIF signal out of the water in one shot- I know that’s what I’d do!There is a company called Wadia, but from what I see they actually modify (I’d rather not use the word hack if you don’t mind thank you very much) the code on the iPod to output the SPDIF signal. The SPDIF is then probably routed to an unused pin on the IPod connector such as 14 or 17 providing they are connected to an IC pin that can support this. They would also need a small 1:1 isolation transformer to output the SPDIF signal to spec’ I believe but I am no expert on this.Even the quality of this depends on how their code interprets the supposed virtual analogue signals decoded by the MP3 decoder. i.e., if the MP3 decoder says the output voltage should go 153mV-164mV-178mV then their code will simply convert these values to what it thinks the equivalent SPDIF output should be. This would however remove any non linearity’s, clipping or noise caused by the iPods analogue stages, leaving you to decode the signal on something decent outside the case of the pod.I admit iPods are terrible, I have a 160G Pod and a 16G 3GiPhone (16G needed for my losless fettish), the pod sounds like a Tandy tape recorder that’s been left in the sink and the iPhone slightly better. Okay for jogging and use in the car but not really home listening. I have the Alpine link box thing too and was going to probe this to hunt for an SPDIF signal but I don’t think I’ll bother now.Best thing you can do to get decent sound from your iTunes library is use the computer you have your iTunes on. Buy a cheap USB to SPDIF converter for £15 (no, it won’t make any difference how much you spend, it’s digital to digital- a 1 is 1 and a 0 is 0, you don’t get 1/2s in binary thank you- it will either work or not and that’s it) Next get a DAC- I use a Cambridge Audio Dacmagic 2 Mk2. The converter does appear to output 48KHz so there’s probably some odd aliasing going on in the conversion from 44.1KHz but it sounds pretty good all the same.The thing about replacing your mains lead is utter crap. I agree completely with “fartface” on this.Just do the simple ohms law and you’ll see you’d have to replace all the wiring in your house back to the fuse box (or really the power station) to make any difference.If your IEC mains cable conductor resistance is 0.05 Ohm that’s 0.05V dropped per amp. Your HiFi won’t be draining more than at the very most three amps, thats 0.15V dropped if your HiFi pulls three amps. If the caps in your HiFi can’t smooth this out then it’s been designed by idiots. Plus the current will settle down after the initial turn on inrush.PS: please don’t call your HiFi mains cable a kettle lead. It is NOT in any way specified to be a Kettle lead and therefore it’s dangerous to use it as one!In comparison the wiring to your fuse box will be maybe 0.5 Ohms? That’s 0.5V dropped per amp from your wall socket to your fuse box! Still, any decently designed kit should handle that kind of transient. Then consider all the drops and interference your supply goes through to the power station via all the transformers, even remote storms, static in the air etc?I’d have said the best thing you could do to clean up your mains was run it through a very clean UPS that removes spikes and brown outs. Or you could plug your HiFi into a ring (or spur if your in the US) that you DON’T have other high current appliances on. If you do have a problem with spikes from other devices in your home you could get a specific ring (or spur) from your fuse box to your HiFi that’s used purely for this. You could also try moving your HiFi away from such noisy appliances.Man, glad to get that rant off my chest!Monty",

All iPods have Arm microprocessors as the main CPU and actually run an os. all of them. it outputs a non-standard digital audio signal and then a secodary dac chip takes care of the rest. This is Primarily the reason for the lack of spdif out, the signal is there, but it does not meet the format standards in order to actually talk to any comercial dac.Also, the so called high end solution u speak of, this dock. It cannot, by any concievable means short of an act of god, produce spdif audio that actually matches the file. The neccisary pins simply Are not there, and there is no way to reprogram an iPod to output extra data on those unused pins without replacing the os.It is simply doing a very good jobthe newer iPods all have encrypted firmware, so even if you thought you could change something: not gonna happen.Want proof? Grab an occilloscope. Compare the “spdif” from that dock and that from a computer with the same file. No matchy matchy",

This prototype serves to demonstrate that the thumb can easily reach any of six TrackPoints in an instant without looking. considering also that each could easily operate an 8- directional piemenu, that is 42 commands that are a single movement away. the thumb has two degrees of movement so it is perfect for operating piemenus. current interfaces ( mice and keyboards ) are crazy – two thumbs for one space bar?!!?!to be honest I just stuck them with the intention of mapping them later – gotta start somewhere. overkill? Yes massively – unfortunately I am stuck with this prototype until I get more thermoplastic, and TrackPoint units. my next prototype will only have one or two TrackPoints, together with some push buttons under the fingers.

Virtual Raid 5 Internet Storage

[wonder] sent in an
interesting
proof of concept how-to on setting up a virtual raid 5 drive that uses free ftp servers to store data. The technique is a bit round-about, but he says it works pretty decently. The shares are mounted under windows with netdrive, then raided by FreeNAS under VMware. I haven’t tried it myself, but I’d probably try to do the same thing, but use
LUFS
and do everything under one operating system.

"content": "But why?In order for a RAID 5 array to work properly at least n-1 disks need to be available. FTP servers that you don’t own/control may not always be available and online. If you violate some part of a TOS (too much data transfer, etc) your account could be suspended or removed. If that happens to 2 of your accounts, ALL of your data is effectively lost.RAID 5 is often used so that you can combine a bunch of similarly sized disks into 1 big disk, and/or for the benefits on the data-reading side where multiple disks are all simultaneously fetching parts of a file.This seems to negate the read benefits, because the ftp servers are going to be too slow to have any real benefit, and the amount of space you get with any ftp account is so trivial compared to the cost of hard drives, combining 4 50GB ftp accounts into a virtual 150GB drive doesn’t seem to have much value.One use for this that could be HIGHLY valuable though, is in storing various bits of illegal data. If you are saving the data in a true RAID 5 striped fashion, then any 1 account would probably not have enough data to extract incriminating evidence. Multiple accounts would all need to be seized and re-combined into the RAID array in order for “The Authorities” to get any useful data.",

Still interesting, just not a hack in my book.That said, I could see it being used, as another poster mentioned, in a security context rather than one which takes advantage of the other usual reasons to implement RAID-5, however to do so reliably it would need many more “spindles” as well as many, many extra parity disks per stripe. The alternative would be to do something akin to CD encoding where a massive number of bad bytes can be corrected. This all assumes of course that several of your ftp servers are down for whatever reason at the same time.Finally, regarding the self-destructing hdd, I’d think that a simple mechanical pucture device would suffice so long as it shattered the platter.

So you have locally 3 (or more) Drives wich can be used für the RAID. an THEN you have 1 Drive wich could be encrypted or could be used for Backup or whatever. Use your Imagination :-)",

If you thought [Johnny Lee] was done making us all buy Wiimotes, you were wrong. Now
he’s back
showing off a simple, but incredibly effective VR head tracker. He swapped out the LED’s on a pair of LED light safety glasses with a set of IR LEDs and used his PC/Wiimote combo to do the work. The demo is just fantastic. As usual, you can download the software from his
project page

What is the frame rate of the Wii remote camera?3.) Assuming the ir targets opperate in a steady state, how can the remote differentiate between targets?4.) Assume POV target #1 is flashing at 10pps, #2 is flashing at 20pps, and the pens are at 30 and 40 pps. Then you could also have one pen as a “left click” and the other as a “right click”.YMMV.",

A wiimote tracks 4 points. 1 person’s head needs 2 LED’s that leaves 2 other LED’s. So theoretically could have a person split screen.Also, since a different wiimote would have to be used to capture infrared on the screen, you could have a two person split screen and 4 mouse cursors.I also think, instead of using the infrared as a touch screen, it should be the mouse cursor. Then combine it with a mouse to get a left and right click. So moving the infrared source moves the cursor but other buttons would actually make it click.

Talcum Powder Print Bot

Will O'Brien

[
"Robots Hacks"

[] |
It’s been
a while
since we’ve seen a new print bot idea. [Kyle] sent in
his groups
final project at Georgia Tech. An ever so handy iRobot chassis, a dot matrix printer carriage and motorized drill bit in a funnel strategically dispenses talcum powder to print messages or images on the floor. Just think, one robot can write all over the floor and the other one can clean up afterward. How long until some sports geeks build a bigger one to deface a football before a big game?

Silent X10 Mod (cheap SSR)
|
Will O'Brien

[
"home hacks",
"Misc Hacks"
] |
[] |
I’m feeling a bit retro for the holidays, so here’s another classic: If you’ve got a non-dimming X10 switch, you’ve experienced the incredibly loud, obnoxious sound that it makes when you switch it on or off. (Mine’s in my stairwell) There’s a simple mod to silence the thing: remove the
triac
relay and
replace it
with a solid state relay. SSRs are a bit expensive, running at least $10 each last time I checked. [Willis Dair] realized that he could
build his own
, inexpensive SSR with an optoisolator and an
alternistor
(AKA Triac). The resulting circuit runs about $3 in parts.

He’s also using a zero-crossing-detecting optoisolator, i.e. what he’s built is _identical_ to a commercial SSR — just not potted in lots of epoxy.Furthermore, unlike conventional relays, SSRs won’t fail after N switchings (due to mechanical wear and that it arcs inside the relay every single time you switch with a load).

PID Controlled Popcorn Popper Coffee Roaster

Will O'Brien

[
"Uncategorized"

[] |
In honor of my espresso machine being fully plumbed in (water supply and drain line!) it’s time for another coffee hack. When I wrote my basic
coffee roaster how-to
, I seriously thought that I’d never see anyone do this, but [] installed a programmable PID controller on his popper coffee roaster setup. This particular PID can be programmed to ramp the temperature over time to create an actual roasting profile, rather than manually adjusting the set points. The original page was
here
, but I had to pull it out of the
internet archive
.

Nightvision Car Heads Up Display

[
"Transportation Hacks"

[alti] wants
night vision
for his car, so he picked up a nightmax night vision camera that has a built in LCD. The plan is to mount the display so that it will reflect off the windshield of his car to create a simple HUD. Unfortunately the image gets reflected from the inside and outside of the windshield. The discussion in the forum is getting pretty lengthy, but it’s an interesting project.

So the projected image is only visible to the driver. You could try to put a polarizer behind the suggested piece of Plexi.Installing the camera inside the car won’t give good results. The main problem you have mit modern cars is their infrared blocking windshield. They are designed to reflect or absorb the infrared portion (or a part of it) of the sunlight. Maybe you can compensate it by increasing amplification. But this increases the problem of scattered light. You have to enclose the room between camera and windscreen.",

DIY LED Multi-touch Panel
|
Will O'Brien

[
"Peripherals Hacks"
] |
[] |
We
mentioned
the
original
IR LED multitouch array a while back, but I ran across
this
DIY version built by [Thomas Pototschnig]. It features an ARM7 controller with USB 2.0 with a 25hz+ capture rate. He’s promised to put up code and schematics when he builds the next version.

I had assumed (like with the LEDs creating current in response to a light incident) LEDs would only be able to detect in the frequency they emitted and that the frequency was fixed:red, green, yellow, blue, purple, IR, … you would think that a red LED would only respond to i.e.680nm – that 400nm UV would be invisible to a red, yellow, green detector. This IR doide, then(and widget) is mapping the current level I suppose(you’re only really seeing a single IR ‘color’)…Oh. OK. I get it?",

DDR Pacman (AKA DDR Pad Rewiring)
|
Will O'Brien
|
[
"home entertainment hacks"
] |
[] |
[Jason] sent in
his
low-tech, but interesting hack to allow the use of a DDR pad with his Gameboy advance to play PacMan. He took a $15 DDR pad, gutted it and wired directly to each of the foil pads that he wanted to use as buttons. For his project, he simply wired each pad directly to the DPad buttons on his Gameboy. It’s really a pre-manufactured version of [fbz] zone switches that she built for her
backpack strap wifi detector
.
By the way, [matt] over at Instructables wanted me to let you guys know that they’re
giving away
a $15k Versalaser.

IPhone GPS Module
|
Will O'Brien
|
[
"Cellphone Hacks",
"iphone hacks",
"ipod hacks"
] |
[] |
The boys over at
engadget
put this up while I was working it over, but I’m still gonna hit it. [Curt] sent in the
iPhone GPS
he put together. He’s using a micro-controller to send the ground toggle handshake we mentioned in the iPhone serial tutorial, along with a small NMEA serial GPS module. After the handshake is completed, the controller hands over the serial port to the GPS output. (Since the handshake only needs the ground toggle, I’d guess that the module is connected to the TX/RX lines all the time.) By the way, the GPS looks like this SiRF II board sold by
spark fun electronics
.

IPod Transmitter Radio Modem
|
Will O'Brien
|
[
"computer hacks",
"Peripherals Hacks"
] |
[] |
[Eric] sent in his
iPod transmitter radio modem hack
(
Internet Archive
). Given the short range of these FM modulators (and FCC rules) I’d call this an academic exercise. Combined with a few mods, it could be useful for bursting data from a micro-controller. (Think APRS)
Asus EeePC Bonus:About a week ago, [johnx]
added
(
Internet Archive
) a 16GB flash drive and a bluetooth adapter to his. Yesterday, [ta2cba] showed off how he
squeezed
(
Internet Archive
) a four port hub inside his – allowing a pair of devices to live in the extra min-ipcie bay and leave two ports to spare for later add-ons.

Autonomous Foosball! (plus)
|
Will O'Brien
|
[
"Misc Hacks"
] |
[] |
[Shane ] sent in GATech’s
senior design final projects
, but his
Autonomous single player foosball table
is awesome. A Java app tracks player and ball via webcam. Then it acts as the opposite player by controlling servo actuated paddles. He’s copied his project to his
personal server
, just in case the class files get pulled next semester.
The course page is pretty ugly, but the project pages aren’t. It’s worth some time to check out the rest of the projects. The 2d
iRobot based mapping system
looks interesting, but lets be honest, the
hand washing detector
should be mandatory federal equipment at every fast food restaurant.

IPhone Serial Access Tutorial
|
Will O'Brien
|
[
"Cellphone Hacks",
"iphone hacks"
] |
[] |
[TheRain] sent in
his tutorial
on using the iPhone’s serial port. Apparently there’s a hardware trick required to enable two way communication. Whatever device is attached to the iPhone needs a secret handshake to get things talking both ways. Once the serial ground has been strobed high to low in the proper order, things will work like normal.

Hack-upgrade Your Magellan GPS

[
"gps hacks",

[
"gps",
"Magellan GPS"

[dgoeken] sent in his
Magellan 3100 hack
. The device runs Windows CE 5.0, and mounts as a standard flash drive. Since everything is easily accessible, it’s just a matter of replacing and modifying the appropriate files. According to the GpsPassion
message board
, some are finding his guide useful for other models of
Magellan GPS
. So far he’s added a file manager, media player and upgraded the Points of Interest file. The site is slightly bandwidth challenged, so I’ve mirrored his hack process
here
.

Adding BananaPC and other apps makes it almost unusable with the ViaMichelin software. If only I could get the SirfStar to respond to other applications I’d use some other gps package on it.",

[Johnny Lee]’s back again with his Wiimote interactive whiteboard. Commercial versions of these things are expensive and heavy. His technique doesn’t even need a projector, just a computer, a Wiimote and a simple IR emitting pen. The pen is just a stylus with an infrared LED in the tip. Hit the video after the break, and you can grab the software from his site

"content": "dan (#34),I’m going to be presenting on the thing at PyCon and opening up the source at that point. For now I’ll give you the quick and dirty explanation.I worked out the math for doing an accurate four point calibration but before I implemented that I decided to implement a very naive version that wasn’t nearly as complex. As it turned out the simple version was accurate enough for my purposes, especially given the fact that the camera is well aligned with the projector so I don’t get much keystoning with either device.What I do is put a red dot in a corner until the camera “sees” it and then proceed to the next corner.Then I define a bounding box within the camera view. I do this very simply by taking the topmost Y value as the top of the box (it could have come from either the upper left or upper right) the leftmost x value as the left of my box and so on. So within the camera’s 640×480 view I have a smaller area that is mapped to the screen. It might be from (80,100) to (500,389) or something like that.If my game surface is 800,600 then I need to translate a point from that box to the 800,600 surface. Let’s say that I find the red dot at (400,220) in the camera’s coordinate system. First I subtract (80,100) to get (320,220). Then I divide by the width of the box (480,289) and multiply by (800,600) to finish the translation. In this case the result is (533,456).If I had a lot of keystoning then I’d need to do use a more accurate transform but the quick and dirty one was always within a few pixels.",

If you need more space to house the battery pick a pen/marker with a wider body for the project. I would think that some of the kid’s Crayola markers would work well with a AAAA or N sized cell.

But still, you managed to get it working…how?I tried my IR-pen by simply using it when I’m in Wii’s sensor bar calibration menu; wiimote sees my pen perfectly when its pointing wiimote. When I begin to rotate my pen, it dissappears when angle becomes greater than ~30 degrees, just like IR-specifications says.Any ideas how to solve this problem?Thanks in advance!",

I downloaded Tux Paint (Open source painting program for kids) and hooked my laptop into TV. Boy oh boy do they LOVE IT! Thanks for the author for this worderful hack!",
