[Aaron] has been working at iweb hosting for about 5 years. When he started, the number of servers was small enough that managing them was fairly painless and could be done by just manually verifying that everything was operational. As the number of servers grew, this task became more and more difficult. They employed various methods of tracking problems, but found them all lacking in one way or another. They got an idea to
build a Defcon status page
based on all of the information collected about their server status. The page was built and all rejoiced. As with most projects, they just couldn’t leave it alone. Next, they built an android app to be able to see the defcon status from their phones. As cool as that was, they felt they needed to have yet another way to keep track. They What you see above is the prototype for the office defcon status display. It is extremely simple, using an Arduino (yes, we know, massive overkill) to receive status updates to change the display number. [Aaron] says that right now it is a mess, and you have to shield it from the light with your hands to see it, but it works. What should the next step be? A giant Alpha Numeric LED indicator? A nixie tube?

There’s a current limiting resistor on the anode; this may not actually be enough, perhaps I do need them on each pin? It was a case of “it worked, it’ll do”.The 4511 is nice, but really parallel ports are a rare find nowadays. I also like the fact that the Arduino shows up as a class compliant serial port. It saves using parapin and having to run as root. Perhaps a bare AVR with a USB library would be a bit ‘thinner’ than an Arduino, but this was just a two-lunch-time proof of concept.@swharden – that was pretty much the first thing that we tagged as a possible for the ‘real thing’.",

[Jared Bouck] over at InventGeek writes about
his experience making his own thermal paste
. Diamonds can be up to five times as thermally conductive as silver, the primary ingredient in most popular thermal compounds. He combines 60,000 mesh diamond dust he ordered off eBay with non-conductive silicon grease using a special mixer he constructed to keep down the dust. After some experimentation he achieved a max load temperature of 38 degrees Celsius versus a leading silver paste’s temperature of 57c on the same system.

The idea is that by spreading it, you’re creating an uneven surface; one which could potentially trap air and make bubbles, impeding heat transfer. I believe that the preferable method is to place a single dab or line right in the center (over the core of the processor), and let the heatsink force it outwards uniformly so that the expanding layer of paste displaces any air and ensures the best possible connection.I wonder if this impacted his test results in any way.",

With
DEFCON
and
Black Hat
going on, a lot of security issues are being made public. This year, cellphones have been a larger target than before. More and more people are carrying complex smartphones that have more ways to go wrong. Even worse, since phones are tied to a billed account, it is possible for malicious software to charge phones discreetly. However,
Flexilis
promises to keep your phone safe. It’s a free mobile anti-virus that works on most smartphones and PDAs with more clients in the works. It also provides easy backup and recovery options, as well as the ability to wipe the phone if it’s lost. The phone makers really need to fix the probelms, but in the meantime Flexilis can provide a quick response.

With Apple keeping a tight control on the apps that run on the iPhone (not the jail-broken ones obviously), they are basically unable to get viruses of any sort.

Defcon
is upon us once again, and that can only mean one thing: new badge designs. Our friends over at Wired posted the picture above along with a description of
this year’s new badge
. Since our
last post
, there has been little new information released regarding the components used for the new badge. However, we now know that it utilizes a microphone and a full color LED along with the Freescale mc56f8006, an advanced digital signal processing microcontroller. [Grand], the badge designer, told Wired that while this year’s design is a bit simplified compared to
last year’s design
, it is not nearly as easy to hack. Just like last year, the functionality of the badge hasn’t been announced yet. We’re hoping for some kind of communicator. Be sure to check out
Wired’s article
if you want to see the high res pictures.

The RGB LED is PWM dimmed alternating R, G, then B on a cycle. The microphone does an FFT on the sound input and determines if it’s over a ‘sleep’ level. It will begin transmitting if this threshold is passed. It also scans for constant extremely high-level noise and when found goes into ‘dance mode’ which is clearly designed for clubbing, where the LED goes wild. I’ll let you know if I find anything more interesting. I’d love to see someone try to make a voice-stress analyzer from one of these.",

[RagingComputer] built this
1-wire attic cooling
fan. He’s using an Ubuntu server loaded with
OWFS
to control everything. The
1-wire
temperature sensor is interfaced using USB while a serial x10 module sends out commands to be received by another x10 module near the fan. Back in the day we had covered a
linux home automation
project. We also covered HVAC hacks such as the
smart attic fan
and a
1-Wire HVAC monitoring system
.

It could have different settings depending on time of day or expected outside temperature within the next few hours. It could cool down the attic in cold summer nights, to help with air conditioning the next day…Would it be more efficient to take advantage of cold air at night for a more efficient cooling, or would it be cheaper to let it get up to maximum temperature and only run the fan when needed?",

The Music visualizer
is actually a second build based on an earlier design[Thanks Roger]. The build was influenced by Zyra’s
How to make an oscilloscope out of a television
. The hack is quite simple, patch the output of an amplifier into the vertical deflection coils of the CRT. This is a good use for that old TV you may have laying around but don’t want to recycle it just yet. While on the subject we had covered the
Mac SE/30 audio visualizer
in 2006. For those looking for something a little more hard core, here is a bit about
Homemade cathode ray tubes

This interesting little sculpture caught our eye. Called the
Perpetual Ball Roller
, it simply rolls a ball on a track. It has both manual and automatic modes with variations in the automatic mode to keep it amusing. This is very elegant, and would be fun to have sitting around to play with. The only problem is the noise. The servo that he is using is quite loud. What could he do to make it function silently?

Mount one or more inductors under the track, normal to the ball’s magnetic field, to create a perpendicular force that will push it around the track. No moving parts, except the ball.I need to do the math though. Since friction in the system is pretty low (metal on metal), the current, hence force, needed to push the ball around shouldn’t be too large. Pretty cool to make it powered with a solar cell. It could be made to appear as a perpetual motion machine (but only with the lights on ;-).",

As for the rail noise, perhaps replace the wires used with insulated plastic wire, or heat shrink tubing around them.

I have actually coded a mode now that uses loops to make very small changes. It is practically silent. I will upload a video of it since it seems to be an area that people first think about.To people bothered about “perpetual” in the title should note two definitions:2. lasting an indefinitely long time: perpetual snow.3.continuing or continued without intermission or interruption; ceaseless: a perpetual stream of visitors all day.Which I think suits this piece quite well as it captures the fact it does go round and round and round.To the comment “sounds like robot sex” that made me laugh.A stepper motor may also work, not sure having never really used one before. Electromagnetics would take this piece away from being a very simple project which means I personally wouldn’t use them. They would give nice silent operation though.As for making it “smart”, that was the original plan. The track wire is insulated so it would be pretty easy and there are plenty more inputs. The thing is it’s not needed at all. The ball just gets into the motion on it’s own. It may take a few seconds but it falls into place. I could use the potentiometer to vary speed but the Picaxe I am using doesn’t have the memory for all the code and I like the “random” motion. I could use a bigger Picaxe but its costs less than £2 which is cool.As for the Arduino, I am aware of them but have never used them. I believe, living in the UK, Picaxe are quite a bit cheaper. I may be wrong so if anyone wishes to correct me, please feel free to do so.",

Make the inner ring move eccentrically in a circular motion (keeping inner ring in same horizontal plane as the outer ring, and not actually rotating the inner ring).It is easy to ensure it is *impossible* for the ball to “fall through” if the maximum gap is smaller than the ball diameter.The “gap” moves around/forward at rate x, and so long as the ball moves around/forward at rate x then all is good. Easiest to imaging ball placed half way between minimum gap and maximum gap.Alternatives could be:a) tilt the inner ring in a rotational manner i.e. connect center of inner ring to a ball joint, make front of inner ring go up/down in sine wave, and the left of the inner right go up and down in cosine wave.b) rotate either the inner or outer ring (keeping the other ring static), and the ball will move at approx half the rate of the tangential velocity of the ring.ridefst: I suggest you should always assume someone has a clue, think about why you could be wrong in your first assumptions, and try not to jump to conclusions so quickly.",

IntoGrafix: Portable TurboGrafix

[Bacteria] tipped us off to his latest
portable system mod called IntoGrafix
. The
TurboGrafix-16
was awesome when it was released. the graphics were, compared to Nintendo, astonishing. Its games were these little cards, like a thick credit card. [Bacteria] wanted to revive his old one in a more portable fashion. He designed a custom case to fit the whole thing into, which is pretty impressive itself. The screen is the trusty old PSone screen. The last time we saw a TurboGrafix, it was in a
mini Arcade cabinet
.

Rotary DECT Phone

"phone"
] |
[Al] sent us over to his
Rotary DECT phone project
, and we think its pretty cool. He’s attending
Hacking At Random
, and as usual, there will be a
DECT network
there. Rather than having a normal DECT handset like everyone else, [Al] wanted something a little homier. He chose to combine the guts of the DECT handset into an old rotary phone. He had to use an Arduino to convert the rotary output to someting the DECT handset could use. There’s plenty more information as well as some source code on the project page.

Making A Tilt-shift Lens

"digital cameras hacks"

"lens",
"tilt-shift",
"time-lapse"
] |
[Bhautik] is on
version 2 of his tilt-shift lens
, and wrote in to share what he has learned. Some aspects of the design on version 1 made it a bit quirky to use. You had to hold the lens in place, manually adjusting the focus. This meant that no two shots were the same. Since [Bhautik] wanted to do time lapse with it, he needed to re design it. He kept it simple and cheap, around $22 total. Version two takes a lot longer to setup for the shot, but the result is reproducible. This means he can make
his tilt-shift time lapse videos
.

It is quite obvious to those of us who are familiar with tilt shift lenses what the strengths and weaknesses are with this hack.This guy wanted to recreate a specific effect without spending tons of dollars. Mission accomplished. He documented it so that people like me, who enjoy both photography and “sticking it to the man” by building cheap alternatives to commercial products.Very much win. I’m definitely going to build one of these. I remembered reading about using a plunger for this ages ago, but i immediately recognized the problems: Manual focus AND you’ve gotta hold the lens in place. Meh. Also, i was worried that lenses for 35mm would not have a wide enough angle of coverage, particularly the cheap DX lenses. The author overcomes this beautifully by using an old Medium Format lens, which will have a 6x6cm or so square of usable image.Quit hatin.",

We’ve printed [John Keppel]’s winning t-shirt design. They’ll be available for purchase in the vendor area at Defcon. If you’re at the con, pick one up because we don’t have any plans yet to distribute them online. We will have a small number of women’s tank tops as well. See you there!

Sewer Clog Alert System

[miketysklar] noticed that a local business was having trouble with their sewage lines. People kept flushing tampons down toilets and it ended up clogging the pump. They had already installed a set of lights and horns to go off when it clogged, but they were hoping for SMS capability so they would know wherever they were.
The new system
piggybacks off the flashing lights by
powering an XBee
when they are activated. The signal it sends is recieved by another XBee attached to a computer running a
python script
. The script then sends a SMS via email to the poor fellow who has to fix it.

This is an interesting little toy. A tiny board that can
display text on an oscilloscope
. The components, or rather just component, is a PIC16F628A. Aside from a power supply, that’s it. It can display 10 characters at a time and, as you can see above, scroll them as well. We don’t really know of a practical use for this, but it would make a nice practical joke tool. If you want some more complicated oscilloscope effects, check out
Tennis for Two

For day two of Black Hat, we sat in on on [Joe Grand], [Jacob Appelbaum], and [Chris Tarnovsky]’s study of the electronic parking meter industry. They decided to study parking meters because they are available everywhere, but rarely considered from a security perspective.
They focused on the San Francisco’s MTA implementation of electronic smart card meters. To start they purchased several meters on eBay just to see the different styles. SF MTA lets you purchase disposable payment cards with values of $20 or $50. They decided to sniff the interaction between the meter and the smartcard using a shim. With that first capture they were able to easily replay the transaction. This didn’t require a smartcard reader, just an oscilloscope. They then took the attack a little further.
[Joe] built a smartcard emulator using a PIC16F648A. They used it to capture multiple transactions and then decoded the interactions by hand. Luckily, the card was using the
IEC 7816
standard so they had some insight into the protocol. They found that the card has a stored maximum value and only writes how many times the value has been decremented. As a proof of concept, they change the maximum value, which you can see on the meter above. They could also have just changed the acknowledgement so that the card never writes any deductions.
The PIC16F648A was a good choice because it’s available in a smart card format called a ‘silver card’. You can find the emulator code and slides from the talk
on [Joe]’s site about the project

"content": "barrel locks are a bit strange. I doubt you could crack it with nothing more than a bic pen, any more than you can crack a typical lock with nothing more than a key sized plastic tab.There are usually either 6 or 9 pins. you still need them all to line up properly (each one has to be pushed down to a different depth, and possibly not at all), and you need to get it to grab the inner shaft and rotate the lock when you turn it.They are easy to hack though If you can get your hands on any two broken keys. Each barrel lock has 9 potential key sets, but only one works in the lock. However there is a ‘programmer’ key that you use to set which of the 9 keys will work. If you can get any one of the keys (even one that is not functional in the lock, due to being the wrong key number) you can easily make a programmer key by cutting the tabs off the inside and outside of the barrel.broken keys are easy to get if management is slightly stupid. A lot of times, these keys have bent outer tabs. the lock is supposed to capture the key when the lock is unlocked. if the key is damaged, it will open the lock but not capture the key. if the op pulls the key out, it usually wont go back in, unless the tab is totally missing. the lock is trashed and has to be changed, since you cant insert a key to turn it back. the key should be destroyed, but usually just gets tossed by less intelligent management.If you can snag the broken key, you can piss people off a number of ways.1 – cut the outer tab off only. it will work only in locks set to that key number. Just as the employee trashed the lock, you can do the same to as many as you want before someone gets wise to you.2 – cut both the outer and inner tab off. its now a programmer key. it wont open anything, but you can set random locks to random key numbers. usually people only carry the working keys, and will find that none of their keys will open the lock. Many sites only buy a few key numbers rather than all 9. (worse is that chain stores often only register one unique pin set, and give each store a different key number. get one store’s key and you can mess them all up) The only way THEY can get into the lock is to either drill it or dig out the programmer key. It sounds simple to solve, but usually the programmer key is locked away in a safe somewhere, and only a few people have access to it.I cant tell you how many times I came to work after a long holiday to find several drilled out locks sitting on my desk.",

The ball bearings are all the same size, and the bumps on the keys are all the same size. When you turn the key it pushes the bearings outward allowing you to turn the key all the way around. When you jam the bic pen in there all the bearings are pushed outward which allows you to turn the bic pen fully. Some barrel locks are a bit stronger and can’t be opened simply with a bic pen, but most are very crappy ($2 to $25) and can be opened with ease. Though u-locks for bikes which have barrel locks are even easier, you can hit it a couple times with a hammer and it’s toast. This is from my own personal experience. When I come across something like this I try it instead of knocking it first.",

They’re made from die cast steel which is very weak. Most bike locks can be broken easily by simply grabbing the lock mechanism and bending it back and forth. Combination bike locks are the easiest, break off just one of those plastic dials and you can slide the rest, the actual dial itself is marked and when you slide the rest you can just turn the dials to the right combination. The only safe way to lock up your bike (still not 100% secure) is to buy a 4 foot length of chain and a strong hardened steel lock that takes keys, and not a Master Lock, Master Locks quite often take the same key, and you can often open Master Locks with other Master Lock keys which are similar but not the same as another one. I had a job once where we needed to use a lot of locks, the owner had bought about 50 Master Locks and half the keys worked on one lock though all of the keys were different.",

I spent alot of time on car-lot’s as a young kid kid (family was in the business) and they had this mike and ike machine. I would take one of their key rings they used (a standard thin-wire key ring, they had boxes full fo them) and spread it out just a hair to the size of a quarter, wrap a few wraps of scotch tape around it, and feed it through the machine. Free mike and ike’s!I showed the salespeople at the dealership how to do it one lazy afternoon, and heard when the candy-guy came by to reload the machine he had a machine full of key rings instead of quarters.A trick I learned after that, you can completely drain a mike-and-ike machine with one standard quarter. Simply put the quarter in and begin turning the crank SLOWLY. Wait until you get the first mike-and-ike or two to drop out into the grab-slot, then twist the crank back counter-clockwise as far as you can (it’ll move about half a centimeter). Now rock it back and forth that half-centimeter or so and if you’ve hit the sweet spot you’ll just keep on pouring them, it takes about 10 minutes to totally empty a machine.",

[Don] had some Serial RFID readers that he needed to
work and be powered by USB
. He went out and purchased a simple serial to USB converter, but was left with the problem of the operating voltage. He supplies the schematics on his site for his solution. Basically he gutted the converter and integrated it all with the appropriate voltage broken out. The final project is nice, using the serial to USB convert as the project box and even including a nice LED to show when an RFID tag has been read.

Ishikawa Komuro Laboratories
are doing some amazing stuff with robots right now. The video above starts out looking like a clumsy and somewhat failed attempt at dribbling a ping pong ball. Once it goes into slow motion however, we see the true action. This robot is dribbling that ball amazingly. Utilizing 1000 FPS cameras, it readjusts and hits the ball on every bounce. As the ball drifts out of the reach of the bot, suddenly we are struck with the lifelike motion.
Personification
can be a fleeting thing, appearing so strongly as the little bot tries in vain to reach for that ball, then disappearing again an instant later. If you really want to see some personification worthy of the
crab fu challenge
, check out their
tool manipulation by a multi fingered hand video
.

Black Hat 2009: Breaking SSL With Null Characters

Update:
The video of [Moxie]’s presentation
is now online
.
[Moxie Marlinspike] appeared on our radar back in February when he showed
sslstrip at Black Hat DC
. It was an amazing piece of software that could hijack and rewrite all SSL connections. The differences between a legitimate site and the hijacked ones were very hard to notice. He recently stumbled across something thing that makes the attack even more effective.
If you apply for a certificate, the certificate authority looks at the common name on the form and contacts the domain owner. The CA ignores the subdomain. The trick is to drop in a null character in the subdomain. If you register,
http://www.paypal.com[null
character].thoughtcrime.org, the CA will contact the owner of thoughtcrime.org and issue the cert. When clients like Firefox use NSS to verify the cert, the null character causes them to think the certficate is valid for
http://www.paypal.com
because they stop at the null character. Even if the person examines the cert in their browser, it will show
http://www.paypal.com
.
Wildcards work as well. You could get a certificate for *[null character].thoughtcrime.org and appear as any site you want. [Moxie] has worked out ways to prevent certificate revocation and browser updates too. This new code will be part of
sslsniff
0.6.
[Apologies for the odd notation. WordPress apparently strips null characters…]

The 2009 edition of the Black Hat security conference in Las Vegas has just begun. The first interesting talk we saw was [Andrea Barisani] and [Daniele Bianco]’s
Sniff Keystrokes With Lasers/Voltmeters
. They presented two methods for Tempest style eavesdropping of keyboards.
The first attack was against PS/2 keyboards. Inside the PS/2 cord, the data line isn’t shielded very well from the ground line, so all data could end up being transmitted back to the building’s electrical ground. The clock signal is also very slow compared to other signals generated by the computer. At about 10-16.7kHz, it should be easy to sample and filter out of the ground noise. They decided to monitor the ground line in an outlet 20meters from the keyboard in question. They used a ~150ohm resistor between the electrical ground and their reference ground. The reference ground was the building’s plumbing and is used to determine what’s actually noise in the electrical ground. They measured the voltage drop across the resistor and used finite impulse response to act as a bandpass filter for 1-20kHz. They were easily able to pick up the keyboard’s signal. It worked so well that they built a remote monitoring board that uses an AVR ATxmega128A1 to do the sampling and send the data over ethernet. In closing, they noted that USB uses differential signaling which should negate any leakage but the processor is more intensive and may end up being easy to pick up. They also stated that many ATMs are probably using PS/2 style keypads that leak this information.
For the second part of their talk, they covered using lasers to collect keystrokes. They pointed a laser at the back of a laptop lid and recorded the resulting vibrations just like a normal laser mic (closer to the hinge provided a cleaner signal). One of the first things they noticed was that the spacebar, being physically larger, created a very distinct signal that was much larger than all others. They used this information to determine where word breaks were. By comparing the captured waveforms to each other using dynamic time warping, they could determine the letter patterns. They then used these sequences with a dictionary to figure out what words had the same pattern and made sense in the same order. It worked quite well and they said it would go much faster if you can guess the context. They mentioned that logos on laptop lids were very reflective and worked well even in daylight and through glass.
You can find
whitepapers and example code on their site

The 1
-Wire HVAC monitoring system
is for residential Geothermal HVAC systems. This project utilizes the so called
1-wire temperature sensor
. A single board computer handles the brunt of the work including
web accessible trend data
. With access to the underling temperatures, the over all system performance may be gauged. Earlier this year we covered a
HVAC web enabled monitor
that adds an element of control. As the industry adopts modern control architectures, we hope to see more HVAC hacks around.

Scanner Sensor Multi Touch

[vimeo= http://vimeo.com/5765795]
[Kyle McDonald] had a Visioneer XP 100 portable scanner laying around, so he started trying to come up with alternative uses for it. In the video above, we can see a
multitouch setup
rigged together using
Openframeworks
in Ubuntu. As you can see in the video, there’s some considerable lag. That is due to the 250-500 ms of buffering built into the scanner. It does have nice resolution; 10k pixels wide at 60 fps, so it has to be useful for something (aside from scanning). Anyone got any ideas?
He says
if the field of view was wider, he’d use it on a river bed to watch fish.

I’ll take a stab at that :)@googfan: The FOV is fine, the DOF is the issue.@devlin: Surprisingly, the scanner doesn’t seem to be bottlenecked by any of its hardware as far as data rate goes. Color or grayscale (or line art/1 bit) didn’t seem to make a difference. I actually got more lines per second from the higer DPI (60 fps vs 30 fps) probably due to physical limitations/assumptions about the characteristics of the stepper motor (or maybe the hardware is always doing full-res scans, then binning). I’m pretty sure the narrow slit wouldn’t work unless you want massive blurring across the sensor. You’d have to actually use a pinhole. Since the sensor is very sensitive, this might work given daylight conditions. Also, measurement applications are great; this could be ideal (if a bit expensive) when trying to determine absolute linear position along a single axis over a fairly limited range.",

[Megatronix] wrote in to show us this pretty crazy guitar mod. He has re wired the pickups to make the guitar a “
Stereo Guitar
“. Generally, the two pickup locations on a guitar are there to provide tonal variation. You can adjust the influence of each to get the sound you want. [Megatronix] decided to re wire the setup so that one is the left channel and one is the right. Thus providing actual stereo sound from his guitar. This will limit his tonal variation considerably, but should at least serve as a proof of concept. We really want to hear a recording of it in action though.

I use an octave box on the bass strings and echo on the treble strings but you can use any configuration you like. As well as the 2 pick-ups for stereo it still keeps the normal Strat input through the 5-way switch for the neck and bridge pick-ups which can be a 3rd amp if you so wish. There is no other guitar that you can buy with 3 jack inputs. It also has a reversing switch for the stereo inputs meaning you can have treble strings coming out one side of the stage and bass strings out the other and quickly reverse them with a quick slide of the switch. This has mind-boggling effects(for me anyway). Email me atsupercopy2002@hotmail.com.Martin(D28).",

The
silicon hacker
behind the
Chumby
, [bunnie huang], was browsing through the
Mobile Phone Megamarket
in Shenzhen, China and stumbled upon an unusual repair book. It turns out the book had the
schematics to hundreds of Nokia phones
. It’s hard to tell if they are legitimate, but the amount of information makes them seem so. [bunnie] claims that the book is a learning experience because it shows how some sub-circuits are implemented. Also, it can be a good reference for sourcing parts. Since Nokia buys millions of each component, the supply of parts they use are stable. There are also editions for other brands, such as Motorola and Samsung.

We’ve seen some crazy speaker builds in the past (
massive folded horns
for example). [DiscoJones] wanted to build a set of speakers that could reach very low frequencies and be very efficient. Instead of constructing a large box, he built a
baffle that could be placed in a doorway
and use the blocked off room as an enclosure. It has eight 12inch subwoofers, eight midrange drivers, and four tweeters. The speakers are fairly cheap and he built a simple crossover to help them work a little better together. The goal was always deep bass though, so don’t expect very high fidelity from a setup like this.

[Extra Ketchup] has a couple Neoware thin clients and thought they would
make a good robotics platform
. It’s a Geode based board that came with Windows CE. He built a small Gentoo system to fit on the 130MB solid state drive. He likes the idea of using it as a platform because the board has serial, parallel, and USB support. The best part is shown above; it can run off of just 4 AA’s.

I’m expecting an upgrade to a small sealed lead acid for longer life for that, plus for driving the motors.You could only expect a Geode to perform XP embedded or Windows CE roles, or light linux builds. Nowt more.You could put XP on if the binaries are compatible, but it’ll run like a dog, and forget Vista!",

The computers are too slow for useful desktop computing, but for projects like a robotics platform, remote sensor monitoring station (using a solar panel), etc., these are a great option. Best of all, they are FREE to me!Regarding 4 AA batteries – this is what I had to test my theory that the board could run off of 4 1.2 volt NiMH batteries (of which I only have AA cells at the moment). This board draws about 1 amp at 4.8 V, not the almost 5 amps suggested. That said, it is definitely my plan to replace with D cells or multiple AA cells in parallel, with separate batteries for the motors (to keep noise off the computer PS).Anyway, what’s pictured is a “It can be done!” experiment, not the final product :-)",

Defcon
, the world’s largest hacker convention, is this coming weekend in Las Vegas. While the convention generally focuses on breaking new technology, digital archivist [Jason Scott] has an interesting surprise for attendees this year. With some help from
VintageTech
, he’ll be assembling a
massive den of retro computing machinery
. They’ll have fully functional systems like the
PDP-11/70
for people to play with. It sure to be one of the more unique things to see at the con.

[Vince Briel] has created an embedded device based on the
Parallax Propeller chip
that acts as a serial terminal. It takes input from a standard PS/2 keyboard and outputs color VGA. It also has a second serial port to connect to a PC for debugging or programming. He is selling kits and has the schematics available. The board has a lot of hacking potential and it could easily be made into a video game or a
Wikipedia browser
.

Suction is incredibly powerful and can be put to use in
several
different
ways
. [Jem Stansfield] built a set of vacuum gloves for a BBC TV series to show how powerful suction really is. He climbed up the side of a 100 foot building, yet had to rely on his safety line near the top. The video of his daring ascension after the jump.

Flex sensors, like the ones used in the
Nintendo Power Glove
, are generally expensive and hard to find. However, [jiovine] demonstrates that they are easy enough to
make from spare parts
. He sandwiched a strip of plastic from ESD bags between pieces of copper foil, and wrapped the whole thing in heat shrink tubing. The sensor is able to detect bends in either direction, unlike the original power glove sensors. His version had a nominal resistance of about 20k ohms, but by choosing a different resistive layer you could create sensors that are more or less resistive.

Sometimes, pets need to be
trained to stay away
from certain things. Over at sump.org, his cats needed to be kept out of his room. He used their natural fear of water by
creating the waterwall
, a motion-sensing device that sprays water. The project is incredibly simple and uses very few components. It is based around an IR intrusion detector and a windshield washer pump. Although that worked well enough, he also hooked it up to his computer via the parallel port so that
he could take pictures
as the cats (or people) are sprayed. Although the project is old, it shows how few components are really needed to achieve this kind of behavior.

[Seth King] sent in his latest hack where he used an Arduino to
regulate various aspects of a greenhouse
. He has sensors for soil and air temperature as well as light and moisture. He
built a custom circuit
that uses relays to power fans, lights, and heaters. Using timers and the sensor data, the devices can be triggered to create the perfect environment for sprouts. He hopes to make the whole thing wireless by integrating XBees, but for now he ran a USB cord to his computer.

The best you can hope for is optical isolation on a communication standard that doesn’t have a direct ground path (hint: RS-485). B&B Electronics sells isolation modules for this purpose . You could build your own easily enough.Don’t forget to use a shield. Enclose your electronics and have a strong shield path.Again, if you get a direct hit, you are done for.",

[Miltron] dropped us a tip about his
NES workbench
. Knowing that when you get frustrated with whatever project you are beating your head against, you need an outlet, [Miltron] decided to build some relaxing NES fun into his workbench. He’s using a NES on a chip though any multi game-in-a-controller setup should work. He has gutted a PSone LCD and mounted it all together nicely so he can game at any moment. You might recall one of [Miltron]’s earlier projects,
Das Uber Airsoft Turret
. How long will it be before we see integrated LCDs into our toolbox lids or workbenches from the factory?

Adding RDS Decoding To A Vintage Radio

"radio data",
"rds"

[Edo] wrote in to show us how he
added RDS decoding to a radio made in 1957
. RDS or
Radio Data System
is a protocol for data transmission. This allows date, time, artist info, and more to be broadcast along with the music. Its a nice feature that many new cars come with from the factory. [Edo] wanted to add it to his old radio though. He kept the radio stock looking, choosing to use an external LCD to display the data. He has posted the information on where to splice in to add this unit to pretty much any FM radio as well as
posting the schematics and source code
for the unit itself. Look at the very bottom of the page for the download link, its a bit hidden with the advertisements.

Bus Pirate Preorder 2 Update
|

[
"News",
"Tool Hacks"

[
"bus pirate",
"microchip",
"preorder",
"preorder updates",
"tools"
] |
A few weeks ago we
held a preorder
for
the Bus Pirate universal serial interface tool
. We split the preorder into two parts due to a shortage of
PIC 24FJ64GA002-I/SO
chips. The first preorder is
arriving worldwide now
, the second preorder
has a longer lead time
. Here’s everything we currently know about preorder 2, it’s subject to change, but we wanted to keep you up to date.
Preorder 2 contains orders for 563 Bus Pirates.
Seeed Studio
noticed an error in our quality control testing routine that misclassified about 50 preorder 1 Bus Pirates as defective. We
updated the test
and passing units will ship immediately to preorder 2 participants on a first come, first serve basis. Another 500 PICs are scheduled to arrive after August 1, which should take care of most remaining orders.
A special thanks to the fantastic engineers at
Microchip
who took the time to peruse the Bus Pirate code, and immediately gave the correct solution to our quality control problem. Great job Microchip, thank you!
We released
an updated version
of the Bus Pirate firmware package. The firmware is exactly the same, we just changed a speed setting in the P24qp.exe quick programmer utility for MS Windows. During development we increased the baud rate of the quick programmer to make development faster, and we forgot to change it back to a safe speed for normal use.

They all came individually packaged and sealed in their own anti-static bag with sticker on! What bright spark decided to take them all out of the reel in which they originally came and put them into a bag?? Bear in mind that these IC’s are less than 5mm*5mm and were put in a bag about the size of your hand. A length of the tape with all 50 in would have sufficed quite nicely!",

[Gary Honis] has been modifying his Canon Digital Rebel XSi in order to do astrophotography. He previously
removed the IR filter
and replaced it with a
Baader UV-IR cut filter
that lets most infrared light through. However, in order to reduce noise in the pictures, he had to
cool the camera down
. He based the project on a peltier cooler that he salvaged from a powered beverage cooler. He made a small aluminum box and insulated it with styrofoam to hold the camera body. The peltier cooler was then attached on the side. It takes just over an hour to cool the camera down to 40 degrees, but the shots come out a lot clearer.

Astro imaging isn’t just point and click, You need the actual images themselves (known as lights or subs) then dark frames, flat frames, bias frames, etc.@ _matt, There is every way that that man with a dslr can take pictures of that quality :) They do it regularly too. check outhttp://stargazerslounge.com/imaging-deep-sky/You might have to go back a couple of months as its not really the best time of year in the UK for astronomy.I have a similar setup to Gary’s (- peltier) and have taken my own long exposure astro shots with some degree of success. There is a technique used called ‘Stacking’ where you take a set of raw equal length long exposures (sub frames or subs) of your target, you then run the subs through software (Deep sky stacker or maxim dl) which ‘stacks’ the images on top of each other, doing this increases (in theory) the SNR and also has the bonus of removing artifacts like satelite/plane trails from your final image, the resulting image after post processing (levels and curves in PS) also has far more detail than any single sub on its own.I’ve been into astronomy for just over a year, its a fantastic hobby all round involving physics, robotics, electronics, computers and imaging and hacking. On a personal level I have built an eletronic focuser (555 timer based) and a Dew heater controller (555 based again) and have a few arduino based mods that I’d like to build too (current one is an automatic dew heater controller that keeps my scopes at a constant temperature using some LM35Z sensors).sorry for the length of this post, I’m passionate about the subject, I’ve been visiting hackaday for yeats but it was astronomy that finally made me pick up a soldering iron and start with electronics :)",

After seeing what I’ve seen, I can believe that those pictures were home-made. There’s a reason why the impact detected on Jupiter yesterday was found by a hobbyist before NASA/ESA/etc. Some of these guys are INCREDIBLY dedicated and down-right brilliant. They’re willing to (like this guy) modify expensive digital cameras, buy/build the highest quality private telescopes, set up extremely long shutter rates, and implement some of the most complex atmospheric distortion compensating algorithms in order to produce the pictures you see. I rank amateur astronomers up there with a select number of hobby communities like Amateur Radio operators and Amateur rocketry enthusiasts where the top tier of the craft have shown themselves to be capable of accomplishing things that even most geeks wouldn’t think possible outside a corporation or government agency. If anything, I think the amateur astronomers even have a leg up on the other two hobbies as, at the very least, they don’t have to worry about, nearly, as much government regulation of their chosen hobby. One last thought, if you check out the caption besides a number of the pictures, it suggests that he is, also, going to special locations (with, I’m assuming, much lower light pollution) in order to take his pictures).As for this project, I’m impressed by his results. Of course, as an armchair quarterback, I have to chime in with suggestions for how he might be able to improve the efficiency:* A larger heat sink on either (or both) side may help.* More importantly, he may want to replace the Styrofoam with some of the pink Dow-Corning rigid foam insulation you can pick up, extremely cheaply, from any Lowes/Home Depot store. The stuff he’s using right now looks like it might be the cheap stuff I got from Home Depot when I needed to block off the space to the right and left of my window air conditioner. I only went with it because I was feeling cheap that day and I wasn’t too worried about paying for a few extra kWh of electricity. For as sensitive a job as what he’s doing, I would think that he’d want every edge he could get. It comes in multiple different thicknesses and even the same thickness as the present styrofoam should provide much higher insulation values due to the fact that it’s specially designed for that purpose.* Also, it looks like some of the edges of the aluminum box are showing through the styrofoam. He, probably, should make sure that the foam overlaps it’s self at the edges and that any other visible aluminum gets covered as any visible parts of the aluminum can be a bad source of heat gain. He may even want to go that extra step and look into using a small piece of foam pipe insulation (which can, also, be picked up extremely cheaply from Lowes/Home Depot) to wrap the first few inches of the telescope eyepiece where it connects to the camera box.* He could, probably, further cut the time it takes to cool by removing the extra components he doesn’t need from the camera (the casing, the flash, mount the camera battery remotely, etc.). In the case of re-locating/rewiring the battery, this could be especially important as a battery being drawn from represents a significant heat source even closer to the image sensor than the Peltier system. An added bonus might be longer battery life as most batteries don’t work well in cold environments. Of course, if the removes the casing, then he’d have to be more careful about the potential for condensation on the electronic components. This might be avoided though the use of cheap silica desiccant like the stuff you find in the bottom of new shoes. Even if he didn’t want to crack open the camera’s case, he should still be able to wire up a battery mock up that allows a wire out to an externally mounted battery.* While it may not improve cooling, he may want to consider trying to put a piece of fine wire mesh (like bug screening, but being careful to make sure it’s made of metal) between the inside fan and the camera. That fan on the cold side of the peltier set-up is very close to the camera and those kinds of simple motors are notorious for producing lots of electromagnetic interference. He may be introducing a new source of noise for the image sensor while trying to eliminate the noise caused by excess heat (though, obviously, the work he’s done has, definitely, produced a net positive).* An obvious solution would be to buy a second cooler, construct another peltier unit, and mount if on the opposite side of the camera but, I’m sure, that’d add a lot more weight.Like I said, I’m just armchair quarterbacking here but if any of these ideas help him, or anyone else, refine his technique even further (assuming he’s even reading these comments) then I more than happy to throw them out there.",

"content": "The webcam hacks are a very simple and cheap way to get into astrophotography, IR filter removal is the simplest of all to do (and necessary), just remove the lens, the IR filter is usually attached to the back of the lens, the more interesting mods are long exposure mod and amp off. anyone that is interested should look for toucam long exposure mods on google, the one I modded for long exposure was a philips spc900nc, I believe there is some work being done on i2c control of these devices….The IR filter is replaced in Gary’s camera with a Baader filter which does still filter IR but at narrower bands so that the juicy stuff (Ha, Hydrogen Alpha) still gets through and the grotty stuff gets blocked. So removal would be useful in IR photography, replacement useful for astrophotogrpahy + it also makes the cameras autofocus work correctly for ‘normal’ photography.Whilst Gary does visit special places to take some of his images it is entirely possible to capture incredibly good images in light polluted skies through the use of LP filters or narrow band filters, the decent ones don’t come cheap, a hutech (borg) LPS IDAS filter will run you around £160, with narrowband filters being a similar price and most narrow band imagers will want 3 (Ha, OII/III, S2) so they can do the ‘hubble pallette’ images :)@ colecomanm, the significance of the filter replacement is probably more than the peltier cooling, it increases the cameras sensitivity to Ha by 5x, this means 1/5th of the exposure time is needed to capture the same amount of data, this has many benefits, less noise in the image, less heat build up, less sky glow noise etc.As for the guys worrying about the cost of a DSLR camera should take a look at the price of ‘amateur’ astro imaging CCD cameras, for a sensor the size of the canon it is ridiculous amounts of money.I would say that 75% of amateur astro imagers haven’t got the funds (or justification with their partner) for a full on astro cam, so they get a DSLR as it has the added bonus of being good at normal photography, + when funds allow at a later date the filter replacement can be done either DIY for the brave or £200 from guys like astronomiser.co.uk",

I guess you could use one that spins at like 500RPM or something to slowly circulate air without getting too hot itself like a mini-ceiling fan.Perhaps if the box was much larger than the camera it might have made more sense though.Also I’d look into adding some copper into the mix, it’s much more efficient than aluminium and might help to avoid having one side much cooler than the other, a few strips of copper to aid the aluminium.",

sends in the logic analyzer he’s been working on
. The logic analyzer boasts an impressive array of features, it can sample 32 channels at 100MHz, 16 channels at 200MHz, SPI, UART, I2C and more. The analyzer’s maximum sample size is 4K for now, and it supports RLE to reduce the memory consumed. The analyzer connects to a java client on a standard PC via USB. The
open source hardware based on a Xilinix FPGA
can be
purchased pre-assembled for $100
which makes it a direct competitor for the
Salea logic analyzer we reviewed
earlier this year.

"content": "Hello, this is Jack Gassett from Gadget Factory. I just want to clear up any questions about this project.This IS the “Sump” Logic Analyzer that has been modified to run on the Butterfly Light hardware. A lot of credit goes to Michael Poppitz for writing the VHDL and the Java client. What is unique about this project is that the hardware is an Open Source design. You can download the Eagle board and schematic files and build this yourself if you are comfortable with surface mount soldering.Linux, this should be very easy to get running on Linux. Urjtag, which is a linux tool, is used to program the Xilinx chip and the client is in Java. I will work on getting this working under Linux and record some screencasts, look for some progress next week.Speed, since this is based on FPGA technology this is very fast. It is surprising how well it works. I’ve used the “Sump” Logic Analyzer for years with great results.If your livelihood depends on a Logic Analyzer then this is probably not for you. But if you are looking to add something extremely useful to your workbench then this is a great addition. What you get is an extremely functional Logic Analyzer right now. But you are also buying an FPGA dev kit that allows you to become involved with other interesting FPGA projects. Planned projects include an AVR compatible processor, Flash Programmer, and Oscope to name a few. Dev kits normally provide a couple examples, once you work through the examples you are on your own. The goal of Gadget Factory is to build a community where more advanced and interesting projects are pursued. Or use the hardware to develop your own project, once you have developed the next greatest thing you can start selling it with the Butterfly Platform hardware. The Creative Commons license allows derivative works to be released under the license of your choosing. Thats the difference from an FPGA dev kit. If you get something running on a dev kit you are stuck because it is not practical to sell a dev kit. But if you get something running on the Butterfly Platform it works just like the Arduino, as long as you provide attribution you can do whatever you like with it.Hope this post is helpful.Jack.",

So I’ve built (together with bushing and johnk) cheapla (http://code.google.com/p/cheapla/), which runs on off-the-shelf spartan 3a / 3e starter kits, can be ported easily to other platforms. It ultimately uses DDR-SDRAM to store the samples, but uses blockram as buffers. This results in a pretty high peak capture speed (120 MHz x 40bit for Spartan-3A, for example, could be tweaked to 240 MHz x 20 bit etc.), and can capture up to 32MB of data (i.e. 4 Megasamples – limited by the on-board ram, so a XUP-V2P could store up to a 1GB of samples, possibly at a lot higher speed). The catch is that the memory rate is limited at about 250 MB/s (S3-A Starter, other boards differ), so the averaged speed (after FIFO) cannot exceed this limit. In the usual jobs, for example sniffing I2C or SPI traffic, this is more than enough. Of course it uses “sample compression” by just storing when signals change, and adding a timestamp.Cheapla doesn’t yet has a software frontend. Instead, it uses a microblaze to provide a HTTP frontend, which gives access to the basic functionality (start, stop, set trigger, set state mask …) and download of the sampled data via ethernet. This makes remote sampling possible. Sample decoding scripts are provided for I2C.I developed cheapla basically to have a “data sink”. It doesn’t replace your scope, but once you found the pins you want to capture, cheapla usually does a great job in capturing. I’ve used it successfully to capture PCI-like busses, long and complex SPI protocol transactions (firmware download, Cell/CBE core configuration)Cheapla isn’t probably what you’re looking for if you plan to replace a benchtop analyzer. But it’s great for everybody who ever wanted to capture a lot of data after knowing exactly what to look for.Oh, and it’s cheap. A Spartan-3A Starter kit costs like $150. You won’t get any useful logic analyzer for less than a few k$. I have a Tek TLA 604 which I hate. I once had a GoLogic U72-2M which was pretty cool, but that thing is (still) $5k.",

[Husstech] wrote in to share his
Snake Bot
with us. Initially inspired by this post about
SickSack, a snake bot
, he set out to build his own version. While the concept and even the design aren’t particularly new or groundbreaking, he is very thorough in his documentation. Since this was a project for school, the
PDF of his project
includes research, schematics, cost breakdowns, and results. We really like the camera and head design, it looks very insect like. You can see a video of the final version being shown off after the break, or you can
see an earlier version
that is decidedly more phallic.

[Jani] directed us to his
tutorial on making a laptop touchpad work with an Arduino
. After seeing the recent post on
touch pad and VFD hacking
, he couldn’t resist finding one of these to play with. He shows us how to connect it all up and offers two methods of using the data from it. The first method is to determine the direction of finger travel and the second, shown above, is to use it more like the volume control on an iPod. Source code for both is available on his site.

The
RepRap project
has been working on bringing 3D printing to the masses by creating a extrusion printer that can also make the majority of its own parts. For the most part, these print ABS or HDPE plastics which are strong and recyclable. In order to create these replicating printers, similar machines called RepStraps are built out of either laser-cut parts or machined elements. They are functionally equivalent to RepRap printers, but are not made of printed parts. [nophead] documented his RepStrap,
HydraRaptor
, that is based off a milling machine. He had already printed a set of RepRap parts, and he
documented printing a second set
. The machine worked for about 100 hours over the course of 2 weeks, printing about 1.5 kg of parts. He made a few adjustments, such as replacing ABS bearings with HDPE to reduce friction. The parts are for
Factor e Farm
so they can get started with 3D printing.

With those three tools in combination you can duplicate each of the three precisely if given a skilled operator, raw material, and consumables.Just because a machine can make a few parts, that when finished with several other tools and pieces of equipment, might be usable for a fractional percentage of the parts to assemble another one, does not make for self-replicating.

I am already getting prints near the quality of the Makerbot that I used to build it, and the quality is improving rapidly. I am sure that within a month, I will be able to print another Kossel kit.While it is true that many of the parts cannot be printed, the difference when comapring a RepRap to another printer is obvious. The aforementioned Makerbot cost roughly $2100, compared to the $700 I spent on parts — and if I had done things more intelligently, that could have been $600. That’s three and a half RepRaps for the price of a single Makerbot, and the RepRaps are faster, have a bigger build volume, and are about $70 away from having dual extruders.Yes, the RepRap project works.

What is good about this thing is the different way of thinking. There are plenty of machines out there that you could make replacement parts with. The real problem is that everything designed today is designed to be thrown away. And also designed to be a big secret. Lack of caring is the real problem, but very few care to change that as long as they can still use a rake to collect their earnings into a tidy pile.Also, I’m not sure how healthcare reform has failed when it has never even happened in the U.S. I can see, however, how all those single-payer systems have failed in all those countries that have them, but have equal or higher levels of care and equal or better average standards of living.",

"content": "@randomguy said:>I’m not sure how healthcare reform has failed when>it has never even happened in the U.S.Newsflash: As it turns out, there *are* other countries in the world, and to their detriment, they have experimented with socialized medicine.If you source your information from someplace other than the usurper-in-chief’s web site or the Obama-news-networks (MSNBC) (CNN) you discover that while all socialized medicine systems look great on paper, they ultimately fail in practice, because they always boil down to rationing. This means suffering and premature death for people the government deems “ineligible” for whatever procedure/treatment is necessary.Case in point: A 22-year-old man just died in the UK from lack of treatment for a bad liver because he drank too much. Now, before you get huffy and argue that he deserved to die… well, so do *you*. You “deserve” to die from lung cancer if you smoke. You “deserve” to die from heart failure if you enjoy steak and hamburger. You “deserve” to die from head injuries if you ride a bike or motorcycle. You “deserve” to die from skin cancer if you spend time outdoors. You “deserve” to die from diabetes because you’re too fat from spending too much time in front of computer reading hackaday posts…etc etc etc. Catch my drift?Ultimately, socialized medicine is most ideal and most attractive to young people who, because of their phase in life, are disinclined to have to make use of the system anyway. Unfortunately, demographics indicate that the population of the U.S. is aging, and that the mean age has been rising for years. Socialized medicine is the *last* thing need.Fiscally, no socialized medicine system is sustainable for more than 10-15 years, after which it goes bankrupt. Talk to some doctors in Canada. I *have*.Finally, there is a *reason* why anyone who lives in a country with socialized medicine, who has the means, will preferentially seek treatment in the U.S. Since I’m not Obama, and therefore not interested in doing all of your thinking for you, I’ll leave it to you to figure out why.",

Meanwhile, people who do have them and are using them look on in mild amusement.Repraps are already being used to fix things as diverse as cars, blenders, and shelving units. They are appearing in Makerspaces where they are used to create parts for a number of DIY projects. There is one in Poland being used to print artificial bone scaffolds – and this is just the V1.0 proof-of-concept design.It is now just over a year since the first machine made a set of parts for a child machine. In a couple more months we’ll be releasing a V2.0Are we improving the quality? No. Are we making it faster? Not really. It’s designed to be easier for people to build, and have wider availability.Why is this? Why not make it more accurate and faster? Because it is accurate enough to replicate, and if you want speed just build another one to double your output rate. Accuracy is now largely a function of software, and being Open Source that will evolve in parallel.What the new design will drive is the evolution.

We noticed
this article on BotJunkie about Archie the helper bot
. Archie is supposed to help out around the house with cooking, cleaning, and other mundane tasks. [Evan] makes a very good point though. Why do people insist on putting creepy heads on their robots. They aren’t making them any more endearing, it’s just creepy. While that is a very astute observation, we would like to add some more. Watch the video above, and study the image after the break. Archie doesn’t seem to be a functional bot. He never moves in the video under his own power. The scene where they “walk” him along is comedy gold. His head keeps falling backwards,or possibly off. And what use is a helper bot that doesn’t have actuated hands? The video is in German, so maybe we’re missing something. Maybe Archie is a mock up or a joke and we just needed translation.

"content": "Hi Guys,I am the young guy (Ahmad Byagowi) in the video who worked on Archie as my PhD work. Long story short description. You may argue, why the robot is not walking on its power. First of all, The project was meant to be done by at least 10 students from several fields. I was the only one from Electrical Engineering. After a short while, Prof. Kopacek was forced to get retired. So, he lost the funding and the institute. So, no further students. I was alone with a robot and getting the minimum requirements in order to receive my PhD. I worked alone and kept faith. After a short while they sent me to Canada to work with Professor Jacky Baltes. I had so many difficulties in Canada, since I had no funding there, and I had to use my 679Euro from Austria in Canada. Nevertheless, I got Archie moving somehow before I brought is to Austria.http://www.youtube.com/watch?v=NACCA-agc1sFor the transportation, I was asked to break down the whole robot in parts to fit in three suitcases (just imagine). Then, when I arrived, I had to demonstrate the robot as there was nothing else in the institute for demonstration. After that I kept working for around 8 months and I received my PhD on March. You may question what is the novelty in Archie. Well, the whole robot is controlled using a central controller which consists from an FPGA running Linux. There is not PC interacting with control of the system. In a hierarchical structure the 33 joints of the robot are controlled using individual micro controller which are communicating with the main controller (the FPGA). The embedded design and FPGA implementation of control system for the robot is really valuable from Electrical Engineering. Because, it can brings up low power consumption and reliability. Besides, the designs can lead the structure to go for commercialization. With all these advantages, I left this field for my post-doc and now I am working on bio-medical engineering. If you like to learn more about Archie, use my PhD thesis.http://www.ub.tuwien.ac.at/diss/AC07806908.pdfDo not compare Archie with other Humanoid robots like Asimo and etc. because, the main goal for this project was designing an affordable robot. Currently, the robot needs more software development, whereas the hardware is almost completed. Also about the creepy head, I agree, but just to let you know, the robot use to be headless (as you can see in this linkhttp://static.startblatt.at/files/blogentry/image/100893/resize400/TU_Wien__Archie.jpg), and mu Prof placed the under development head on the robot before the press conference, just to make it look more like a humanoid. This is the whole story. If you have any further concern, please do not hesitate to contact me.Thank you for you time",

Ceiling Fan POV

We know some of you are getting sick of POV projects,
but this one was just so cool
, we couldn’t resist. [UncleBone] thought POVs were pretty cool, and wondered if he could use one on his ceiling fan. It would have been a breeze just to toss something like the
RGBike POV
on there and call it finished, but he designed his own. Opting to blow away the norm of using a single row of LEDs, he chose to do 5 different rows of LEDs, one for each blade. The whole thing is controlled by an Arduino, with a spreadsheet for image manipulating. Unfortunately, we don’t see any source files for the project available. Maybe he’ll put them on there if we ask really nicely. If he could get it playing animations, we would just chill and watch it for hours.

[onezerothrice] has been working hard on creating
ARtisan
, a flash library for bringing augmented reality to the browser. His goal in creating the library was to make
AR projects
quicker and easier to develop. The library can provide the location, size, and rotation of multiple markers on screen with little work from the developer. It is licensed under the GPL and comes bundled with
Papervision3D
, another flash library for manipulating objects in 3 dimensions. He has posted several demos with source and accompanying video.

Gentle Safe Cracker

"safe cracking"

[Carlito] found a safe in his garage with mystery contents. It shows signs of attempted entry and makes interesting noises when shaken. What is the best solution to find out what is inside? Hack it open? Smash it? Blow it up? No, the best solution is to
build a robot to try brute force cracking
. The robot, housed in an old power supply case, is little more than a servo and a servo controller, communicating with his PC via USB. It seems like a good idea though. Unfortunately, he found it to be seriously lacking in torque, so he’s waiting now to upgrade. The contents of the safe are still a mystery.

Basically, the number of operations needed to brute-force the combination could be reduced from approximately 50^3 (125000) to 2*50*3 (300). If I recall correctly, it had something to do with feeling the amount of backlash for different combinations.I think it would be a whole lot more difficult to automate, because the algorithm would be a lot more complicated, and you would need some kind of sensor to measure the backlash or torque, but it would also find the combination much faster, if it would work, ofcourse.I recall that many of these locks have so much backlash that you could be 1 digit off, and it would still open. In that case, a regular brute force would “only” take some 7813 combinations on average for a 3-cam lock.",

The only problem I see with that is if you have to turn more than 1 turn but that could be solved with 2-3 times more teeth on the rack than the pinion.",

"content": "After reading the comments I’m surprised that only one other individual suggested a manual means of opening it. Don’t attack the lock the way the lock designer intended: be inventive and you could have this open in a couple of hours, if that.Locks are notoriously vulnerable. One safe I opened, only had a spring holding the bolt into the door jam of the safe, so if you could slip a sliver of plastic into the jam it would pop open with literally no effort – and no guessing of the combination. Every lock has flaws. Exploit them!Chances are you’re looking at a 4 number lock with an anti-forcing mechanism inside. The mechanism will give away clues as to what numbers are likely to be part of the combination but you’ll have to use your *hands* and your *ears* – not a servo – to find out what they are. Once you’ve narrowed the range of numbers and thrown out all of the numbers that are too close together to be valid, your chances improve significantly. Finally, you can literally throw out the 4th number because most of these locks will automatically stop the dial when the correct combination is entered. Essentially, you don’t even have to try turning the handle to know that you’ve gotten it right.Read a book on safe cracking. I don’t mean to be a wet blanket, but this isn’t really a good electronics project. Your own senses and a bit of knowledge will have it open much faster than a computer could do the same.",

"content": "looks like a pretty old safe. i’d say try manipulation, but i get this feeling the mechanism sucks enough at this point that it’ll be difficult to do that, especially given that he says he needs no torque–you usually need almost nothing to turn these guys. Also, it’s not clear exactly how you dial in the number.Actually, if you’re going for this, you REALLY need to figure out the correct method of dialing in the number. Let’s just say I’ve gotten screwed over by this. In case you haven’t realized yet, dialing in a master combo lock isn’t the same as dialing in a safe lock at all.Also, you don’t need anything to push open the door. The way safe locks work, turning the combo lock will actuate the bolt once you get the right combo. If anything, you need some means of sensing that the wheel won’t turn anymore (wheel gets stuck after actuation in one direction)Drilling is probably a lot easier. The locksmith had to use one of these guys on an atm machine probably because ATM machines use significantly more secure locks and are probably class I manipulation proof locks.The best way to drill this guy is to probably pick the drill point on one of the four sides of the lock. Unfortunately I’ve got no clue which direction the assembly is mounted, but if you’re lucky you’ll be able to read off the combo from the discs. If not, you’ll probably at least get to drill out the fairly soft bolt/actuator and get the thing open.Another hint (VERY IMPORTANT)–if you’re not going for the drill point, don’t go through the front. It’s a total trap and waste of time. Trust me, I’ve been there.",

It’s certainly not designed into the lock – most have anti-manipulation features which pretty much avoid this.Listening for the clicks rarely works. What you need to do is feel for the “contact points”, and from this you can infer certain information about the wheels. It’s not nearly as simple as just feeling the points and saying that is the combination.The problem is that only mid-range locks are susceptible to manipulation, especially by unskilled hands. The really low end locks mask the contact points with grinding. High end locks have mechanical features to mitigate the attack, as well as being made to tighter tolerances.This paper explains it more thoroughly:http://www.crypto.com/papers/safelocks.pdf",

4D Systems micro drive
provides both raw and FAT level access to microSD cards. The module contains a dedicated host controller that transforms what may be an otherwise intimidating card spec into a group of simple serial commands. With a wide supply range of 3.6-5.5 and .1″ lead spacing, this should be cake walk to tinker with. The device doesn’t support FAT32 yet. According to the
GOLDELOX-DOS command set
page 9, “FAT32 is currently not supported, if you mount a FAT32 formatted disk, you will not be able to access it at all, both FAT and RAW commands will fail”. At the moment the device seems limited at 2GB FAT16 partitions. This sure does seem like cheating after implementing SPI and Nibble mode SD card protocols.

People were finding it cheaper to buy an iPod Nano and crack it open for the Microdrive than to buy the Microdrives OEM. (The only instance in which I can point out that Apple actually was able to provide something equivalent for LESS.)Microdrives are capable of roughly 4 to 8MB/sec in data transfers, so no, they’re not blazingly fast… but work. There are Compact Flash cards (Sandisk Ultra III series, for example) that are capable of UDMA modes and higher speeds. Microdrive just was preferable because it was cheaper per MB before and provided near infinite rewites compared to flash… in which both ways, Flash has since exceeded Microdrives for all intents and purposes.But it’s all besides the point as the picture clearly shows that it’s a MicroSD flash card in a socket.And yes, those are fast enough for MP3 players, too.",

Defcon 17: Early Badge Details

Every year, the Defcon badge takes a technological step forward. The
details are starting to emerge
for this years hardware lineup.
Last years badge
, pictured above, had LED status indicators and an IR transceiver. There’s no telling what this years badge will do, but we do know it has a new processor. They have chosen the Freescale MC56F8006 to build everything around this year. We think it would be cool to see some RFID, maybe a heat map of the traffic in the facility. Maybe some distributed computing would be cool. What could we do with an embedded camera? We eagerly await more details.

[HyPe] over at the Natural User Interface Group developed this concept as part of his Master’s Degree in Industrial Design. This
suitcase sized projector and computer
allows people to have a 60″ multitouch screen available wherever there is a large enough surface. The current software is designed for ad-hoc meetings about large-scale construction plans. The rolling case includes a short-throw projector and webcam. Just set it on top of your work surface, lift the lid, and it’s ready to go.

However I intended the use of wireless pens to transfer accurate notes and drawings – budget and time-wise this was not available for me at the time.Furthermore deadline for the graduation date was too close to refine this more.If you don’t touch the surface, the camera system will not detect your hand, since nothing reflects the laser light. Because of occlusion in the camera system, putting your elbow on the table does not matter much.If you flip the suitcase, and put it against the wall, you have a wall projection, which is also touch enabled -tried it, but a normal white wall is much more icky to touch than the smooth meeting tables.",

For months we’ve used our
Bus Pirate universal serial interface tool
to demonstrate
electronics parts
, so it’s only appropriate that the Bus Pirate get it’s own parts post. We recently had a
Bus Pirate preorder
, and today we received the pre-production Bus Pirate prototype from
Seeed Studio
. This prototype was mailed just a few days before
preorder 1 started to ship
, so those packages should start arriving any day.
Follow along as we unbox the prototype Bus Pirate, and connect it to a debugger to determine the
PIC24FJ64GA002-I/SO
revision that shipped with this board. Use this post to share your own Bus Pirate unboxing experience. Pictures and discussion after the break.
Most Bus Pirates will ship
in a padded envelope
(JPG), but ours came in a box with some PCBs for future projects and an AVR programmer.
Inside the box, the Bus Pirate is protected by a
static dissipative
bag. The Bus Pirate pin headers are stuck in foam to protect the packaging.
We ran a battery of functionality tests that covered USB, the user terminal, protocol libraries, power supplies, and pullup resistors. Everything passed our tests.
Next, we used a Microchip ICD2 debugger/programmer to make a backup of the firmware prior to doing a test upgrade/downgrade with the bootloader.
Connecting to MPLAB ICD 2
…Connected
Setting Vdd source to target
Target Device PIC24FJ64GA002 found,
revision = Rev 0x3042
…Reading ICD Product ID
Running ICD Self Test
…Passed
MPLAB ICD 2 ready for next operation
All of our previous Bus Pirate version were built using Rev 0x3003 (A3) of the PIC 24FJ64GA002. Version A3 has a few issues, known as
errata
(PDF), one of which is a
flaky hardware I2C module
. These chips aren’t ‘defective’, they just have a few quirks like any complicated integrated circuit. The Bus Pirate firmware works around these issues using software techniques. Most desktop computer processors go through a similar stepping process.
Our Bus Pirate appears to have a B4 revision PIC (0x3042) that corrects some, but not all, of the errata from A3. This is no guarantee that every Bus Pirate will have a B4 PIC, preorder 1 and 2 are both sourced from multiple international vendors. Additionally, there’s no immediate benefit from having a B4 chip, someone will have to write software that takes advantage of the hardware. The next firmware update will print the PIC revision in the user terminal, check the
nightly compiles
if you’re anxious.
There is a revision B5 mentioned in the PIC errata. Some of these might find their way into preorder 2 boards.
Now that you’ve got your Bus Pirate, what do you do with it? We’ve got a bunch of
part demonstrations
to get you started.
Please leave a comment about your unboxing experience, and the devices you plan to interface.

Volver is a 3.75 inch square LED matrix
that will display over 1600 unique patterns. Designed by members of Image Node and Disorient, it is a fundraiser for burning man 2009. While it is certainly less colorful than its
older sibling the Nodeblinky
, it features 8 more LEDs and a bit smoother and faster graphics. Volver can be picked up as a kit, or fully assembled from their site. Just like last time, you don’t have to buy from them. They freely offer the
source code and schematics
.

[Agent420] brought up this
touchpad and VFD
hack in the comments on our
capicitive sensor guide post
. He had broken dell laptop from which he harvested the touchpad and an HP laserjet that contributed the VFD. Though the touchpad communicates using standard PS2 protocol, he wanted to use it with his Atmel 8535 AVR which required him to write some custom code. In the picture above, you can see the VFD displaying the coordinates of his finger. You can download his code as well as the spec sheets for the different pieces on the project thread.

We’ve seen tons of stuff hooked up to send updates to twitter when something happens. That’s what we expected when we first read this tip from [Matt]. We were pleasantly surprised to see he’s actually doing the opposite. He has rigged several items to an IoBridge module and he can
control them by sending tweets
to his account. In the video you can see him sound a buzzer and change a display on an LCD. Its nice to see twitter being used as part of the control as opposed to
updating us every time someone flushes
.

And not the fact that your paying 100 dollars for something that can only do 4 different things at a time without reconfiguring it,t though that can be expanded with PIC’s or AVR’s, its the fact that you are adding another point of failure to your system.Anytime you make a net enabled system, you automatically have 2 points of failure, your home, if the power goes out, or your net connection dies. And however your accessing it. Your pretty much not going to get around that.With this, instead of interfacing directly to your computer, you go through a third party.If they were to go out of business, your SOL, if their dataserver goes down, your SOL.Also, your letting a third party have complete access to your system. Granted, its a company, so it most likely wont be abused.But I would much rather put together an old p2 or p3 box, load up linux, run it as a server, and issue commands and whatnot directly to it.

No proprietary I/O interface card necessary, full automation of whatever, via twitter.Side note, you can configure twitter accounts to be not visible to the public, anbd if you tell noone about this account you can well use it for your own automation steering purposes. You could even implement a password check when fetching tweets via twitterAPI so each tweet would need to include this authentication before it could effect something. Just my 2 cents..",

[Don] was having issues with dust when working with MDF. He had a shop vac overheat and die because of it. When looking for solutions, he saw several systems that used
cyclonic dust seperation
. Not wanting to buy something he could make for cheaper, he left the store and started scrounging parts. You can see
his home made system
in the video above. This seems like an absolute must have item for any workshop. Great job [Don].

Since a cyclone is rotating, the coriolis effect may play a part. But you are correct that it doesn’t have anything to do with whether you are in the northern or southern hemisphere. The earth rotates so slow that this only makes a difference for extremely large things like oceans. Likewise, the centripital force due to Earth’s rotation is not very significant (or is that centrifugal force? I can never remember).There is a nice video on youtube showing the coriolis effect when some kids are tossing a ball around on a merry-go-round. When you are standing on the ground, the ball goes in a straight line, but when you are spinning with the merry-go-round the ball’s path appears to be a circle.",

in conjunction with an Arduino. The available Arduino code wasn’t that great so he rewrote it to be easier to understand. The AD7746 is an I2C device that can be continuously read, but this doesn’t mesh well with the Wiring libraries. Additionally, the calibration routine from the data sheet is difficult to understand. He’s included all of the code he used plus a Processing sketch to help visualize the input which will hopefully make your experience with the chip much more smooth.

Solving the age old problem of… wait, what problem are they solving? These students at UC Berkeley have built a
toilet paper dispenser prototype
. Not only does it meter out an exact amount for you, it will fold it and cut it as well. They mention this being the perfect accessory for a high tech bathroom, and we can agree. To be serious though, in public places, metering out limited amounts of toilet paper at a time could possibly result in major cost savings. We think the next prototype should have different preference settings such as; wadded, folded, or wrapped around your hand. Anyone else’s mind suddenly filled with unpleasant imagery?

That way, you could have an icon-based touch screen which lets you punch in a length or you could pre-program some commonly used amounts, like for example: Pressing the burrito icon gives me just 2 feet, but pressing the chips and hot salsa button provides me with the full 10 feet required for the job.Version 2 of this app would offer voice recognition and it would allow you to just describe the consistency of the stool.

Build A Wireless Keylogger

Hardware Keylogger solutions has
released the plans and files
for their wireless logger. It has a range of about 50 yard between the transmitting dongle and the receiver. It is based around an Atmel AT91SAM7S64 and the PCB is pretty tiny. In case you hadn’t noticed yet, they sell them as well. The cool thing about this is that key data is transmitted in real time, allowing you to see it as it happens instead of
having to go retreive the log physically like you used to
.

I’d only do it for USB as I rarely see PS/2 used anymore.The reason I wouldn’t bother with this is because of the cost and it’s still too bulky. ps/2 isn’t too popular anymore either. people who are a real threat with this stuff would make a bus tap solution with my idea and have it inside the keyboard.",

Both use interrupts though a single IC/map controller.They must have good resources because I priced the project around $40 which is what their non-soldered kit costs.I’ve seen custom ones that where used in industrial espionage. They where a super small PCB with just a asic and 4 passive surface mount components bus tapped in the keyboard casing with a trace style antenna. the chip basically retransmitted the USB data and sent what was in the buffer out on bluetooth. what’s interesting is it was bus power.",

The other two types are bluetooth and infrared.That board it just a thrown together circuit proving an algorithm. people are going to buy it though and realize how useless it is without redesign shortly after.one thing worth noting is a keylogger is for the most part useless without a good bootkit and/or economical feasible design; expect it to be found. Using it for the mentioned “legit” applications is silly considering they are 3x the cost of existing solutions in most cases.There are high level of abstraction application processors out there that could by themselves make a wireless PS/2 USB hybrid keylogger with the addition of a few passive components for a fraction of the cost of all others.",

Dating back to September of 2007, this certainly isn’t new news, but its new to us. This is
Little dog
, the miniature version of the
ever so creepy
Big Dog
. We aren’t sure if the lack of Big dogs signature jogging in place makes this little guy seem more lifelike or less. Little dog was designed to be a research platform into study automated navigation of natural terrain. We wouldn’t mind having one of these around the office, though we would have to add some kind of a head or face to give it some character.

They “race” across the different terrains by pre-computing paths through them, optimizing them for the robots available movements, and then use some interesting control algorithms to get actual movement close to the planned path. They don’t know the terrain until the competition, so compute time is part of the race. I think the most interesting aspect of the competition is that it is not done with team hardware, the algorithms are sent off and used in a controlled setting for testing without the teams even being present!If you are interested in controls I would highly recommend you look into this a little further.",

Here is a nice video to wind down the day. It’s [neorazz]’s micRo
playing the theme from Tetris
. The
micRo
is a simple CNC kit sold by the team at Lumenlabs. For more servo music, peruse our
CNC category
.

adafruit industries’ latest product is an
adjustable breadboard power supply kit
. We’ve seen breadboard supplies before, but like most of adafruit’s kits, this is the best design you’re going to encounter. It uses an MIC2941 voltage regulator instead of the more commonplace LM317. It has a very low dropout which means your output voltage can be much closer to the input voltage. Their example is using 3AAA or a Li-Ion battery for an output of 3.3V. Input can be through a barrel jack or terminal blocks. There is a selection switch for 3.3, 5, and adjustable voltage. Using the adjustment pot you can select an output voltage anywhere from 1.3V to within .5V of the 20V maximum input. The adjusted output voltage will remain the same even if you increase the input voltage. Like all of their kits, you can find
schematics
,
assembly
and
usage
instructions, on their
project site
.

Therefore, the current threshold that triggers the protection is most likely high; probably high enough to incinerate something flimsy like a prototyping or a bread board into nothingness. Anyone using an ATX supply should attach a current limiter to the output.",

$15 HDR Camera

"photography",
"viliv"

[Steve] was planning a 15 mile hiking trip when he came up with this idea. He wanted to get some good HDR photography, but didnt’ want to lug around his 5D MKII. He managed to pick up a couple of cheap Polaroid X530s. These have decent optics and record in RAW format, which is pretty impressive for something he got for 99cents plus shipping. He had all of the buttons
wired for external control via a Viliv umpc
. As you can see on his site, his results are quite nice. Of course, you
don’t actually have to hack your camera
to make HDR images.

A few weeks ago we held a
pre-order
for
the Bus Pirate V2go
, the first official Hack a Day hardware. We had initially hoped for a group purchase of 20 or 40 Bus Pirates, maybe 200 if it was extremely popular. In total, nearly a thousand Bus Pirates will be made.
The first 350 Bus Pirates (pre-order 1) have already been manufactured and tested.
Seeed Studio
has done a great job handling the orders, pre-order 1 should start shipping more than a week early. How long will it take to get to your mail box? It will vary for everyone, but our packages usually arrive from Seeed in 7 days.
Seeed sent us pictures of the Bus Pirate depaneling, programming, and quality control process. Check them out after the break.
A panel of Bus Pirates.
Depaneling
, also known as cutting a big sheet into individual circuit boards.
Visual inspection of each Bus Pirate.
Programming the
unified bootloader/V0g firmware
via the ICSP header.
Testing the bootloader and terminal interface after programming the firmware.
Completed Bus Pirates are stored on anti-static foam, we like the shiny quality control stickers.
Individual Bus Pirates are cut out for packaging.
Finished Bus Pirate packaged in an anti-static bag.
A box of Bus Pirates ready for handling.
One Bus Pirate, ready to ship. This might be be yours.

Apparently, it came without any firmware loaded, and I needed to “just know” to go upload firmware to my device. What exactly the “QA passed” sticker on the bottom means… I’m not sure.Anyway, anyone else who got a preorder 2, you need to go to buspirate.com (Didn’t know that existed until now) and there is other info at dangerousprototypes.com.-Jonathan",

We have often commented that we’re a bit tired of hearing random notes when someone sends us a musical project. We love home made instruments, circuit bending, and creative sound, we just like some intentional direction to the noise. This just might be an exception to the rule.
This typewriter plays random notes as you type
. While it might annoy your cohabitants into a violent rage, it seems oddly cathartic. We have heard people talk about the pleasure of hearing the keys clack as they type. It just seems like you would get used to this and find it just as pleasurable. Maybe we’re crazy. Unfortunately, they don’t divulge any technical details, but we can imagine a simple way of wiring directly into a cheap keyboard to get the same effect.

Lunar Lander Remade

For those that are lucky enough to remember it, Lunar Lander was a fantastic game. Though it had simple vector graphics and highly repetitive game play, it kept us captivated. We probably lost entire weeks of our lives competing with friends to be the best. Well, now we can relive that experience with a
physical version of the game
. [Lain] built this fantastic arcade style game to replicate Lunar Lander’s game play exactly. The style of the project is fantastic with giant analog meters and dials giving real time feedback. You even get a prize if you complete all 3 levels. You can get plenty of build details by going through
his blog
. Maybe he should hook up with the folks that built the
Apollo landing computer replica
to build the ultimate simulator.
[thanks Mike]

Embedded above is a neat
augmented reality business card
by ActionScript developer [James Alliban]. After seeing “
the most impressive business card you will ever see
“, he was inspired to update his own business card. His new card has a fiduciary marker on the backside and directs you to his site. A flash app on the site displays a video where he tells you more about himself. The 3D grid of planes in the video varies in depth based on the brightness of the section. He has a few more
AR and tracking demos on Vimeo
.
Updated:
While we’re talking augmented reality, it’s worth checking out the tech behind
ESPN’s baseball tracker that uses doppler radar
.

Professional cameramen use steadicams to make their shots look smooth and clean. However, their prices are generally way too high for an indie’s budget.
Previous attempts
have tried adding a counterweight and moving the camera away from the hands. [YB2Normal]
took a different method
and used a bob and gimbal to hold the camera upright. The gimbal is free to rotate along 3 axes, so the camera can stay in place. The whole thing cost less than $15. The first video he made with he mount is after the break.

All it does is make the camera 10 times heavier at the bottom and give you another spot to hold it midway. This Gimbal version actually does a nice job at stabilization without adding a horribly disproportionate amount of weight… and does more at stabilizing the image other than making it too heavy for you to “shake.”",

We found this
Arduino AVR ISP programmer
particularly interesting. AVR microcontrollers can utilize an interface called In-System-Programming. ISP allows the chip to be programmed or reprogrammed while in an actual circuit via a pin header. Atmel’s solution is the
AVR ISP MKII programing tool
. The MKII can also be reprogrammed just as an AVR. The difference here is that most people are not likely to modify the MKII to be used as anything but a programmer. On the other hand if you already have the Arduino,
fetch the avr.isp.03 firmware
and AVRdude. Then program a device, for example an
ATtiny13
using the Ardunio as the programmer. All the project information is provided under the CC BY-NC-SA 3.0 license. On a related note we covered a
Microcontroller cheat sheet
which covers AVR devices and ISP pinouts.

"content": "ReKlipz,Consider that you may modify the firmware to do batch programming without a PC. Could also add an SD card and LCD screen. Contain hundreds of builds on a single board. This would work well for small distributed hardware that requires updated firmware. Sure there are plenty of other projects that do the same thing and support gang programming.The Arduino in general opens up the doors for the hobbyist who may otherwise have no place to turn. Some are very likely to broaden their horizons and move on.The last i checked the MKII was ~$30. About the same price as the Arduino. Get a .1″ protoboard from radio shack (assuming they still carry em) to bring the ISP signals out. Worst case is we have to bit-bang(slow)program the Arduino with the firmware. Then move on to the higher speed serial programming.Now a few disclaimers. Being old school i understand and agree with most of the complaints about Arduino based projects. When i see a Microcontroller used to blink an LED, i gripe and moan pointing out a thousand other ways it *should* have been done using cheaper, smaller, less power consuming methods.

And then – the absolute kicker for me – I CANNOT SOLDER EVEN 1/10th inch center boards any more because I’ve got “intention tremor”. I’m great at large movements, but the finer the control I attempt to exert, the more my hand(s) shake. Kind of makes SMD useless, I fear. I must agree with the person who asked “Why do this at all?” I suppose it has to do with an obsessive “DIY” ethic or something. Personally, I’d LOVE to buy such a device (pre-programmed) at a decent price, but I simply am not capable of building one. Poor little me, eh? Oh… I _can_ buy one of several choices over the Web?

Integrated Steering Wheel Radio Controls

[Graham] bought a new stereo for his Peugeot 406. Unfortunately, the built in radio controls in his steering wheel didn’t interface directly with the head unit, but rather with the vehicle itself. His solution was to
build a device to decode the button presses
and send them to the head unit in the appropriate fashion. All source code and schematics are available on his site. He states that this should work on any PSA/Renault vehicle with a 125Kb VAN bus. We’re curious how similar some of the American systems are. We have seen something similar where someone wanted to
control their Zune
from the steering wheel.

We’ve all seen those little toy helicopters appearing everywhere. They’re getting cheaper and cheaper with some models getting down to roughly $30. The JRL team wanted to be able to control them with a PC, and figured the best way to do it was to
build somewhat of a universal remote
for them. The HeliControl module currently has several different types of copters programmed in, and they plan on adding more. Its not surprising to see the rise in popularity of these mini choppers, we’ve even seen some pretty extensive mods to the bodies and even mechanicals. Click around
this forum
to see what some people are doing to them.

[Steven] was inspired by the
BlinkM
and
Shiftbrite
modules, but really wanted something that could be controlled via RS232. He decided to
build his own RGB LED module capable of PWM
that fit his needs. He’s using a PIC16F628 microcontroller as the base. Each module has 4 individually addressable LEDs with multiple intensities for each color. The units can be daisy chained as well. The schematics and PCB files are available on his site for download.

, or a simple two-wire protocol. The protocol type is set by resistors on the back of the display, so it’s not particularly easy to change without a
hot-air rework station
. Today we’ll demonstrate a serially-interfaced VFD using the Bus Pirate.

We used our
Bus Pirate universal serial interface
to demonstrate the Futaba VFD, but the interface operations will be the same for any microcontroller implementation. The connections we made between the VFD and the Bus Pirate are shown in the table above.
We setup the Bus Pirate for raw2wire mode (menu M, 7) with
open drain outputs
(HiZ). The open drain outputs let us interface the 5volt VFD from the 3.3volt Bus Pirate using the on-board pull-up resistors (menu P, 2). Finally, we enabled the on-board power supply (capital ‘W’).
The VFD’s strobe pin is connected to the Bus Pirate CS pin. The auxiliary pin doesn’t have it’s own pull-up resistor but CS does. CS is otherwise unused in raw2wire mode, so we reassigned the auxiliary commands to the CS pin (menu C,2).
Interfacing
The two-wire interface uses a straight-forward 16bit (2byte) protocol (datasheet page 20). The LCD control bits (R/W, RS) go in the first byte, and eight data bits go in the second. All transactions start with strobe low and end with strobe high. Read operations are similar to writes, except the R/W bit is set and the second byte is read.
The Futaba VFD accepts all the standard HD44780 LCD commands (datasheet page 27), see
these tables
for a detailed description of each command. After a reset (power-up), the VFD expects the first command to be the function set command.
RAW2WIRE>@
<–start with strobe high
AUX HIGH IMP, READ: 1
<– aux pin (CS) is now input, pull-up resistor holds strobe high
RAW2WIRE>a 0b11111000 0b00111000 @
<–command
AUX LOW
<–strobe low
WRITE: 0xF8
<–start byte (R/W=0, RS=0)
WRITE: 0x38
<–instruction byte (function set)
AUX HIGH IMP, READ: 1
<–strobe high
RAW2WIRE>
Function set configures the data interface length (bit 4), display lines (bit 3), and brightness/luminescence (bits 1,0). Before we start we set the strobe pin high (@) in case it’s currently low. Then, we start the transaction by taking the strobe pin low (a), and send the first byte with the R/W and register select (RS) settings.
The second byte is the command. We set the data interface length to 8bits (bit 4 = 1), but in serial mode this is probably ignored. Our display has multiple lines (bit 3 = 1), and we set brightness to full (bits 1,0 = 0). The sequence concludes when the strobe pin returns high (@).
RAW2WIRE>a 0b11111000 0b00001111 @
AUX LOW
<–strobe low
WRITE: 0xF8
<–start byte (R/W=0, RS=0)
WRITE: 0x0F
<–instruction byte (display on/off control)
AUX HIGH IMP, READ: 1
<–strobe high
RAW2WIRE>
The display ON/OFF command enables the display (bit 3), toggles the cursor (bit 1), and blinks the cursor (bit 0). We enabled the display (bit 3 = 1) with a blinking cursor (bit 1,0 = 1) so it’s obvious that the display is working.
RAW2WIRE>a 0b11111000 0b10000000 @
AUX LOW
<–strobe low
WRITE: 0xF8
<–start byte (R/W=0, RS=0)
WRITE: 0x80
<–instruction byte (DDRAM address set)
AUX HIGH IMP, READ: 1
<–strobe high
RAW2WIRE>
Before writing characters to the display we need to position the cursor by sending the DDRAM address set command (0b10000000) summed with the desired cursor position. We set the cursor to the first character on line 1.
The second character on line 1 is located at 0x01. To set this address we’d send 0b10000001 (0b10000000 +0b00000001).
Character display memory isn’t linear, the first line starts at 0x00, the second line starts on position 0x40, the third at 0x14, and the last line begins with position 0x54. Most displays have a similar configuration, here’s some
tables for determining the layout of different character displays
.
RAW2WIRE>a 0b11111010 0x48 0x61 0x63 0x6b 0x20 0x61 0x20 0x44 0x61 0x79 @
AUX LOW
<–strobe low
WRITE: 0xFA
<–start byte (R/W=0, RS=1)
WRITE: 0x48
<–ASCII letter ‘H’
…
WRITE: 0x79
<–ASCII letter ‘y’
AUX HIGH IMP, READ: 1
<–strobe high
RAW2WIRE>
Finally, we can enter some characters at the position set with the previous command. Characters are entered as their
ASCII equivalent values
. We displayed “Hack a Day” with proper capitalization.
Multiple characters can be entered at once, but because the memory space isn’t contiguous it’s necessary to manually position the cursor at the beginning of each new line. After writing the last position of line 1, the cursor will advance to the first character of line 3. Use another position command, 0b10010100, to set the cursor to the beginning of line 2 (0b10000000 + 0x14 = 0b10010100).

This is an
interesting instrument
. Part laser harp, part guitar, the Prism seems to have some potential. [Jeff-o] put some major time and effort into refinishing a guitar, building the circuit and putting it all together. He did a great job, the instrument looks fantastic and appears to work. We do have a request though; please post a video of it being played as an instrument. So many of these electronic instrument projects just spit out random noises. While we understand that some people are into that, we would love to hear some control. How about intentionally changing notes to make a melody? Based on the description, it should have control for pitch, and even speed of the oscillation. So let’s hear some music. We don’t care if you’re any good, just please play some music with it. If you would like to build your own, he has the schematics and PCB layout available for download.

The green laser damaged the pigment layer of the retina, although it did not cause a measurable decrease in the visual function of the patient’s eye. Dr. Robertson believes that longer exposures could harm vision, however. He also warns about potential damage from higher-powered green laser pointers. “With the use of laser pointers that are more powerful than five milliwatts, there would likely be damage to the actual vision,” he says. “Functional damage could occur within seconds.”",

"content": "jeff-o,You cannot assess the damage laser is doing to your eye by assessing if it is dazzling your eye or not. People who work with really powerful lasers can get a hole in their retina in a split second of focusing their eye to the laser beam (even when it is reflected, if the reflection surface is highly reflected and the beam is strong enough) This is painless and you wouldn’t know that you’ve damaged your eye until you realize that there is a spot in your vision that doesn’t go away. Granted a 10mW laser cannot cause this type of damage, but prolonged exposure would cause damage to your retina. This project is using 10mW laser which is way stronger than it needs to be (5mw would’ve been enough). Also even thought it is not as cool, red laser would’ve been much much safer.More importantly, when you focus to a bright spot with your eye, even if it is reflected, you are collecting all those beams of light and focusing it on a tiny space on your retina, that is intensifying the power of the laser, and you are doing it in a short distance of 2 feet. Even worse for the kid in the video as he is several inches away from it, and he doesn’t know that he shouldn’t look at a green laser for a prolonged period of time.",

So, I may as well use red lasers instead even through they’re not as cool.In the meantime, only adults are allowed to play the Prism, and my kid will get a different instrument to play. A sequencer, maybe? I have to decide!",

[Eric] sent in this very informative writup on
how to use Photo interrupters
. These things can be used for many things, he lists pellet dispensing and limit switches. He found one in his junk box and realized he knew very little about it. After some exploring and research, he’s here to educate the rest of us. There’s a good breakdown of the circuit itself which is pretty simple as well as a test circuit and some sample code.

I just picked up some OPB460s (http://www.farnell.com/datasheets/89728.pdf).

We’ve covered weed whacker bicycles before
and you can even buy 66cc conversion kits now. [geoff390] posted a few videos over on YouTube about another motor option. In the first video embedded below, he
goes over the basic parts of his bike
. The chainsaw motor is mounted to the side of the back tire and a metal drive wheel extending from the chainsaw shaft makes contact with it. The motor assembly is mounted on a hinge and the friction between the drive wheel and the back tire is adjusted with a turnbuckle. He posted a
more detailed second video
in which he goes over some of the finer details of the bike and some of the issues he’s had.

"content": "My impression was that this was Hackaday, not Innovationaday. Maybe this is not new technology or technique, but it’s certainly a hack. I don’t get what people are complaining about.The fabrication is all custom. Some of it it pretty smart – like using brake cable for the accelerator since most frames have cable bosses incorporated into the frames. And it seems that all the complainers about friction drive overlook the fact that his design was a quick, easy way to motorize the bike and keep use of the pedals, a good idea if the rig breaks or he runs out of fuel.I’m glad some of you can buy a kit for $200, but how is that a hack? This rig could probably be built for about $40 in yard sale finds, or for free if you have a well-stocked yard shed. Yes, it will wear through tires quickly but this looks like a budget/fun project, and around here, you can get free tires from the local dump all day long.I dunno when the posters on this site got all negative, but it’s a bummer. If you don’t like a hack, you could be a heck of a lot more constructive in your criticism, or move on to the next article. I didn’t read a single complaint on this page that couldn’t have been phrased constructively. How about supporting the hack community instead of putting people down?Kudos to Geoff390, I think this was a pretty interesting project.",

A door hinge and turnbuckle is a very solid design.His throttle control was pretty spiffy as well.Also, for a lot of chainsaws a spindle would actually be a very decent way to power it considering that modern chainsaws run at about 12-13000 RPM. So, say his bike has a 16 inch tire and the spindle is 1.5 inch in diameter that gives him a 10.67:1 ratio and a theoretical speed of 53.6 mph@12000rpm although losses included he probably can get up to 30mph.

[Michael Davis] sent in
his homemade laptop tray
. He does a lot of traveling in his Toyota Tacoma and was looking for a good way to mount his laptop inside. Unfortunately, [Michael] soon discovered that commercial laptop trays can be very expensive and difficult to install. He saw an opportunity in the empty cup holder in his car. Fifteen dollars worth of PVC pipe fittings and a piece of plywood later he had a laptop tray.

It’s original intent might be for the overworked traveler, but it’s sure to attract the overeager multi-tasker. While someone who needs to be in constant contact with coworkers (like hospital personnel) might just use it intermittently while stopped and taking breaks, others might use it whilst driving and loose concentration on what’s really important; the road. Yes, there are people everywhere that manage to put on makeup, check a navigation system, or flip through some CDs for music, but when a computer comes into play, we all know that its bright display and many buttons are simply irresistible.

Honestly $80 is cheap money for a device that is designed to protect an expensive laptop.I’m all for hacking things to improve on an existing product, or making something for your own entertainment/experimentation… but I really hate hacks that are for the sake of saving a buck especially when they end up unintentionally dangerous.",

Maybe even a fender washer with some foam rubber on it and a single screw in the bottom would prevent a possible tear-out of the cupholder.An ounce of prevention is worth a pound of cure.The basic design is not at fault, quite ingenious and elegant actually, you just have to rely on your cupholder being strong enough; which is sadly not the case on many vehicles.",

Strobit looks like it could be a project to
keep an eye on
. The entire project is open source, including the hardware. The aim is to build a low cost, low power, wireless enable arduino powered widget. This seems like it could really cut down on the development time of many projects we’ve seen here. Development is still ongoing but it looks like they’ve already implemented some mesh networking similar to the
zigbee systems
.

As with most electronic musical instruments, we saw this in the tip box and expected the usual random noises to show off the instruments range. Consider us pleasantly surprised. They cut strait to it and
showed us what la Guitare à crayon really is
. It is an instrument of both audio and visual art. You draw while you play. The guitar appears to have a wacom attached to the front where you would normally strum. different areas of the wacom seem to effect the music much like a string being plucked. In one of the videos we see some fret board action as well. Watching the screen, we can see that she is drawing a picture, and we are in fact hearing that picture being drawn. The site has a section for source code, but states that it will only posted if there are requests. We are officially requesting it, we want one. May we suggest some improvements? Get some color variation, possibly opacity too. Gimp can do it with the wacom. We can’t wait to see how this project matures. How about another video? Watch it after the break.

Last month, in preparation for
Defcon 17
, the qualifiers were held for
capture the flag
, one of Defcon’s most well known events. One participant, [mongii], did a
writeup on how to solve problem B300
. The challenge was to find the decryption key used by a program that had several twists that hindered debugging. After grappling with self-modifying code and junk instructions, the team was finally able to find the answer. This win helped Sapheads place in the top 10. Over at
xchng.info
, they are collecting solutions to the other problems. Sadly, they’re not all in comic form.

Why not do the entire reversing work “offline”, on some sort of a _model_ CPU ?Call it a VM if you want, or call it an emulator, whatever. In my profession, it’s called a simulator; and it seems to me that it would make reversing so much easier. I’m positive that a cycle-accurate hardware model of the basic x86 architecture already exists, so it would suffice to write a “PE Loader” testbench for use in the freeware version of some simulator, to have a step-by-step timeline of what is actually going on in an executable.",

Excited about google Chrome? Can’t wait? Why not play with google’s other OS, Android.
You can now run Android from a live cd on any X86 computer
. Just pop it in and go without any damage to your existing data. They’ve already gotten it working on the EEE_701, let’s see one with touch screen installed.

With digital cameras getting cheaper and higher quality, we find ourselves more capable of using them to make videos.
A Snorricam
can be a very useful tool if you like the effect it produces. This specific design allows for adjustment of the height and angle of the camera allowing for even more possibillities. As you can see in the video after the break, it seems to work pretty well. It might be nice to add some kind of vibration absorbtion though. Anyone got any ideas on that?

There are no microcontrollers in this project. In fact you wont find a single transistor. This
classic regenerative tube radio
, modeled after an early 20th century homebrew is complete with schematic and additional photos. For those who are not familiar with tube designs and for simplicity, the regeneration circuit can be thought of as feedback though this relation may be argued. Read the rest after the break which includes a crash course in tube operation.
A basic vacuum tube generally consists of a heater, grid, and plate. A current is passed through the heater which as the name suggest, creates heat. This allows electrons to “boil off” under proper conditions. That is the hot heater emits electrons when the grid and plate are positive potential. Opposite charges attract so the electron is attracted towards the grid and plate. The grid has holes very much like a screen door does. Some of the electrons pass through these holes missing the grid and strike the plate. The greater the electrical potential the greater the attractive force in the grid and plate. When an electron is permitted to move from one potential to another an electrical circuit is created. This circuit forms the basics behind vacuum tube operation.
With that said, the project uses a heater powered from two D size batteries. There doesn’t seem to mention of the plate source, though we suspect a few 9 volt batteries wired in series does the trick. Some of the newer
commercialized radios
(World War II era) operated from considerably higher heater and plate voltage potentials, rendering the common shock hazards associated with tube designs. Tuning is accomplished with an air cap and
home made variocoupler
. We covered a
VFD based regenerative reciever
earlier this year.

If you use two batteries for filament you need to put a silicon diode in series to drop the voltage a bit, because it’s designed for 2V and 3V will eventually burn it out.

Etching a printed circuit board generally takes a bit of time and uses a lot of etchant. [TechShopJim] posted
a method that uses a sponge
to reduce the amount of etchant used while speeding up the entire process. First, a resist is applied using either a sharpie or the
toner transfer method
. Using gloves to handle everything, he soaked a sponge in ferric chloride and continually wiped a copper-clad board until all the exposed copper was removed. This technique moves the etchant around more, keeping “fresh” etchant closer to the copper. If you can’t procure ferric chloride, you can also use
our method
that uses 2 household chemicals: hydrogen peroxide and hydrochloric acid.

"content": "I’ve been working with FeCl for about 25 years now (I started when I was around 10 yrs old). The stuff is safe, though it stains bad. It wont hurt or burn if get it on you but the stain will last 1-3 weeks and look strange to others. Stains on cement or floors can be permanent after it dries. Ingestion? I dont know, very small amounts probably ok, but take a good gulp and it could lead to iron poisoning.FeCl fumes are not so much toxic as just an irritant. However, keep metal appliances and stuff nearby away, fumes could condense on them and ruin the finish. (I’ve seen it firsthand.)I’ve been using this guys system for a few boards:http://www.pulsarprofx.com/pcbfx/main_site/pages/much better than regular tonor transfer. After the tonor transfer you treat it with some green leaf and then the resist pattern is *very* tough to get off…as in, sandpaper has a tough time.I then use the sponge to etch and it is definately faster and more effecient than constant agitation. It’s all about getting the used FeCl away from the copper surface to let the fresh FeCl do its work. The sponge is also cleaner, just trust me on this. You use much less of the resist and your not adjitating it and dripping it everywhere.Today I am trying a new ferric chloride mix with citric acid (Edinborough mix) that is supposed to facilitate the evacuation of the used FeCl from the copper surface to let fresh FeCl at the copper. I’ll post the results.",

The official Arduino Nano design has been
updated to version 3.0
. Like other new Arduino designs, it’s using the ATmega328 instead of the ATmega168. It’s also a slightly more reasonable $35. The small board is designed to be plugged directly into a breadboard and accessed via mini USB cable. This new design is also two layers instead of four making it easier to produce and modify. The new Nanos will ship at the end of the month.

At its simplest you can borrow a friend’s programmer if avaliable, load a bootloader on it (also easy, just look it up) and then from then on you can load code via serial. It’s really not hard to start programming AVRs on the cheap. Also check out Sparkfun.com, they have some good tutorials.-Taylor",

This project provides an opportunity to conduct near space experiments. The flight computer,
BalloonSat Extreme
, is controlled by a BASIC Stamp 2pe. The complete BOM with PCB artwork is provided. There is enough hardware to control cameras, servos, a Gps, and five digital I/O. The computer is also equipped with a 12 bit ADC to log experiment results. The device seems limited to 30KB of storage. Though the author suggests this memory limitation is more than adequate, we are wondering if an implementation of the Nyquist sampling theorem is in use at all. For further reading the author has provided information regarding
Amateur Radio High Altitude Ballooning
.

[Mangonha] has put together this interesting project involving
aluminium can recycling
(
translated
, sortof). They’re using an arduino to tally up how much aluminium they have accumulated. That information is then passed on and displayed on a google map. There are families that go around collecting the cans as a means of income, and this system could be very helpful to them. They state that their goal is to eventually have restaraunts and more families included. We’re a bit curious about how helpful this really is. How is that information actually changing the actions of the collectors? Would a simple flag on your door or window signalling enough cans to pick up or not be just as effective?

Robots Learning Facial Expressions

Researchers at UC San Diego have been working on a
robot that learns facial expressions
. Starting with a bunch of random movements of the face “muscles”, the robot is rewarded each time it generates something that is close to an existing expression. It has slowly developed several recognizeable expressions itteratively. We have a few questions. First, are we the only ones who see a crazy woman with a mustache in the picture above?
Why is that
? What makes [Einstein] look so effiminate in that picture? Secondly, what reward do you give a robot? You can actually see this guy in action in a video after the break.

Neural nets can implement fuzzy logic, reasoning, decisions, etc, so it’s fair to say it’s using fairly complex AI technology.

Maxim’s
iButtons
, which are small ICs in button-sized disks, are starting to show up in more and more places. They have a range of uses, from temperature loggers to identification, and all use the 1-wire protocol to communicate. Over a
furrtek
, they hacked an iButton used for buying things from vending machines and created an infinite money cheat. They built a small rig based on the ATmega8 to read and write data to the chip. The data was encrypted, so it wasn’t feasible to put an arbitrary amount on the card. Instead, they used a similar technique to the
Boston subway hack
and restored a previous state to the iButton after something was bought. They also created a hand-held device to backup and restore the contents of a button for portable hacking.
[Thanks furrtek]

Using an
MSA-T MIDI Decoder
from Highly Liquid, [Rob Darman] was able to take the MIDI output of his Roland V-Drums and use that output to control fire shooting cannons, forming a setup that he calls fire drums. As seen in the video above, the response time between the V-Drums and the fire drums is pretty impressive. While this is by far one of the coolest things that we’ve seen controlled by MIDI, we’re naturally thinking about taking this to the next level; MIDI-controlled fireworks, anyone?
You may remember the MSA decoder devices from people wiring up
MIDI drums to Rock Band

It seems that our french friends over at BlogEEE.net have gotten their hands on a prototype of the Asus EEE Keyboard all-in-one keyboard computer. After plugging it in and messing around it a little bit,
they decided to take it apart
. Although BlogEEE.net is in French, we were able to learn several things about this prototype. According to the site, the PCB in their EEE keyboard is marked as Revision 1, meaning that it is very possible that this could be the finalized version of the PCB that will be seen in retail units. Also, they mention the presence of a Silicon Image sil1392cnu, a chip responsible for sending HD graphics via the EEE’s onboard HDMI port, supporting resolutions anywhere from 480i to 1080p. Perhaps one of the most impressing details uncovered was that when weighed the EEE keyboard clocked in at an impressive 2.1 pounds, lighter than most keyboards that don’t have an onboard CPU or display. While we’ve learned a lot about the Asus EEE Keyboard so far, there is still no information available regarding its release date.

It runs PalmOS for applications, and really it functions as a typewriter for students. Obviously not nearly as advanced by this, as it came out in 2002 and has being barely upgraded since, but its good for what it does, and the 24-hour battery life, SD card, and USB ports are nice.Anyways, this that’s what it reminded me of, but this is different. As somebody above mentioned, the screen on the side is pretty much useless. Put it on top where you can easily see it, and it would be good for taking notes and things like that, but where it is you can really only use it like an uber-sized extremely awkward PDA. Neat, but I think it needs work.",

Those that have keyswitch modules use them as the mounting point while those keyboards using the normal rubber dome + membrane technology use them as stiffening. They’re still widely used today – the last compact keyboard I bought (£45) had one.Also, there’s cheap and there’s cheap. Genius, trust and other makes you get at a supermarket are going to fall apart but you shouldn’t have to spend much to get a reliable keyboard. My Microsoft Internet Keyboard lasted eight years and was still going strong when I swapped it out for a mechanical keyboard (the best mass produced keyboard ever, the Dell AT102W) but I don’t know what microsoft’s current keyboards are like. If you’re in Europe then Cherry’s Cymotion Expert is certainly popular in some corners and should last some time. I know cherry aren’t that popular in America though, but Aparently newegg does a 45USD deal on the ABS M1 from time to time which is a mechanical keyboard complete with metal plate that should last you a good few years (specifically it’s uses Strongman-type Simplified Alps keyswitches). Or you could always grab a Dell AT101/AT101W from ebay as you should be able to find new boxed ones fairly cheaply (which uses the original, and some feel better, Alps design keyswitches), they also have a steel plate.A model M eeeboard would be interesting, if you used the guts of an M mini inside a full sized M case then you might be able to get away with no work except wiring the screen into the numpad hole. M minis are expensive though, unless you can bag one with missing keys and cannibalise the full size M.And yeah, while most keyboards might not weight more than this there are a lot that do, and 900g is pretty impressive considering my eee 701 weights slightly more and contains almost the same components.",

For those who watched the Tour de France, you may have been pleasantly surprised to see some cool tech. Nike was using a robot to paint pictures on the street in chalk dot matrix style. It was accepted by the general public as new and innovative, as well as generally cool. In the hacker community though, a bit of trouble began to brew. The
Chalkbot bears more than a passing resemblance to a project called GraffitiWriter
. GraffitiWriter was a bot
initially designed
to protest the militarization of robotics. As it turns out, one of the early developers of the GraffitiWriter is behind the Chalkbot in a legitimate contract. The trouble doesn’t seem to be one of intellectual property legalities. People are mad at the corporatization of public work. They want kids watching to know that this system was designed by regular people in their spare time at their homes, not by a team of researches in a secret underground Nike laboratory.
The article takes a bit of a turn and talks some about the possibility of projects being taken and used for corporate advertisement. The specific item they are talking about is the
Image Fulgurator
which secretly projects images on objects in your photographs. You’ll have to go check that one out to see how it works.

Of course.Personally, I think it’s unfortunate that someone creative sold out to a corporation, and it’s especially ironic that someone protesting the militarization of robots is okay with using them to promote a company that has a history of using sweatshops and still contracts with factories that utilize questionable labor practices.",

Some companies insist on using proprietary pieces. It can be really frustrating when there is no apparent reason other than consumer lock in. It irritates us to feel like we’re being forced to buy their pieces. This is one of the more popular reasons listed when you ask a hacker or modder what got them started. This project takes us through
making a normal power supply work with the compaq proprietary 14 pin plug
found in some smaller desktop PCs.
Aside from the plug itself being different, the motherboards require a 3.3v standby voltage. A normal power supply usually only has a 5v. Though there are even simpler ways of bypassing the issue, he chose to put an inline voltage regulator. Schematics are available on the site.

The majority of people I’d be selling to if I were compaq would probably throw away their computers and get a new one if the power supply (or anything, for that matter) broke. The only people it’d target are maybe the 1% non-corporate, technically competent people who happen to buy one of these computers, and it’s not worth it to screw them over if unless there’s some greater advantage (cost).Now that I read it again, I’d imagine having 3.3V standby has something to do with making solution size slightly smaller for the smaller desktop towers. It almost certainly wouldn’t be very significant (just one less 3.3V regulator onboard somewhere), but that plus the decreased cost makes it a no-brainer.",

This ancient by internet standards, circa 2002, but its a great read.
[Eddie], frustrated by the high cost of ink cartridges set out to build a continuous inking system
. This would mean that the cartridges would be filled from larger, cheaper reservoirs of ink continually. Along the way he transitioned from simple tubes with some putty to more complicated systems. Eventually he had to
hack the chips that told the printers the cartridge was in need of replacement
. While the systems he’s using may be difficult to find now, the execution should work on other models. Completely unrelated to the project itself, is that [Billy Mays] as the site favicon? We suspect it is [Eddie] himself.

Contrast that with the 35 milliliters they ship with and you can see that you can go through a lot of printheads.When we switched to HP we also regularly ran 2-3 liters of ink before degradation began to set in.The best thing for cleaning a dirty printhead I ever used was Simple Green.

I tried all sorts of things from dunking it in hot water, to the same with isopropyl alcohol, 50/50 alcohol/water, running printhead cleaner (the FixYourOwnPrinter “epson printhead cleaner” which fixed it the first time) through it, and finally pumping low-pressure air through it (which killed the head completely).I eventually scrapped the C86 for parts.

These 15 ton robotic arms can reach 16 meters. Not content to control them by a simple joystick,
the team hacked together WiiMote controls for them
. Ok, we get it. Everybody loves the Wii. What is different about using the WiiMote in this scenario? You can see that they are only using the pitch, yaw, and roll. They’re not utilizing the tracking aspects at all. The only difference between the WiiMote and their joystick in this scenario is that the WiiMote connects via bluetooth. Frankly, we just like the fact that people are playing with the robotic arms, WiiMote or not.

When [Tom] got tired of the large size of his Microsoft Comfort Curve 2000 keyboard, he decided to hack a recently acquired Apple Adjustable Keyboard for use with Windows. After removing the ancient ADB based control board from the Apple keyboard, he was able to map the keys and transplant the Microsoft keyboard’s USB control board into the Apple keyboard. After soldering the control board into the keyboard with old IDE cables, all that was left was to add some diodes to prevent ghost key presses, and
the keyboard hack
was complete. [Tom] offers a spreadsheet of the results of his key mapping on his site, and while you’re there be sure to check out his other projects, like his
DIY Proton Pack
that he made for Halloween last year.

Every year [Len Bales] designs and builds a new clock. His 2006
clock runs on the classic Intel 8008 microprocessor
. The design is definitely not for the faint of heart, but he includes all code, diagrams and a good description on his site. The project is an interesting look into the not-so-distant past of computing. While the function of the project is a clock, it is actually a fully programmable 8008 computer running at 500khz with 16k of memory space and 4io ports. [Len] also links a lot of useful 8008 resources for anyone wanting to tackle a project of their own.

Over at SpriteMods, [sprite_tm] realized that a
microcontroller could be used as a boost converter to power itself
. A boost converter steps up voltage from a battery by switching the output of a coil. First, it is tied to ground so a magnetic field can build up in the coil. It is then released as a higher voltage than the input. Normally dedicated chips do this at an incredibly high frequency, but the PWM signal from an AVR works well enough. This can be used in low-power situations
where space is an issue
.

Here is a classic project used to increase wireless signal strength. Cantennas focus using a waveguide very much like a magnifying glass focuses light. [Robert] made a
Natural Light beer cantenna
, pictured in the upper left. His approach used three beer cans, a paper towel holder, and a shower curtain rod. On the
tipline
, he noted a signal boost from 11Mbps to 54Mbps. This is certainly something we can hack together if our room lacks adequate signal. Read about parabolic and seeking versions after the break.
The lower right image is an example of a
parabolic soup cantenna
constructed using an old satellite dish. No figures seem to be cited, though the construction is worth noting. We’ve had success with
old satellite dishes
in the past. The upper right and lower left pictures are scanning Cantennas. They use servos to seek out stronger connections by moving and checking the signal strength. Below is an in line video of the lower left
cantenna while scanning
. Maybe you want to know
How to build a tin can waveguide WiFi Antenna
. All the instructions are provided complete with a rough cost break down, and the site has a calculator to determine cut off frequencies given a can’s diameter.

The dishes that dish network and directv use don’t actually see the signal coming in directly at the face but from 5 degree’s (might be less or more, just woke up and heads fuzzy still)above. For instance the standard dish that Echostar uses to say pick up signal from 110E would have an elevation of 30 but the signal comes down at an elevation of into the face of the dish at 35 degree’s. Knowing the elevation of your source transmitter will help but you will run into a problem with the elevation settings on the dish assembly not having ticks any lower than say 25 so you will have make your own markings to go lower. Once you have that done and the elevation set to 5 degree’s below that actual elevation of the source you just need to face the dish in the direction of the source and fine tune, the nice thing about these dishes is they have allot of slop built into them to get signal from sats and as such should work well.",

Tiny Medical Bot

This
tiny bot wants to go inside your body
. That’s right, it was designed to travel through veins. The little bot has no on board propulsion system. It is controlled by a magnet outside the body. See those little spines? Those straighten out to keep the bot in place when it isn’t supposed to move. Creepy right? In all the articles we’ve seen on this bot, there aren’t any details about what actually is on board. They mention adding a camera in the near future, but why are they calling it a robot? Surely there’s something cool in that little body. This is a quite practical application of a
project we covered recently
. Commenters weren’t impressed with the external control system, likening it to the old vibrating football player game. Well, here’s where it could be usefull.

We would like you to
meet PR2
. Made by Willow Garage, PR2 is a platform for research into robotic programming. The bot itself is simple compared to some of the humanoid bots we see, but its behavior is quite complex. In the video above, you see PR2 completing milestone 2 of its development. This includes navigating an office with closed doors and plugging itself into a standard wall outlet for a charge. We’re especially fond of the “wiggle”. You can hear some of the developers talk more about PR2 and its completion of milestone 2 in the video after the break.

Giving us a chance to break out the
TLAs
, [Blair] sent in his latest hack where he
embedded an RGB LED into his EeePC
to display twitter, pidgin, and email notifications. It is based around the ATtiny45, and requires very few additional parts. He based the project on a
foundation of work
laid by [Dennis Schulze] on notifications and the
work of [Dave Hillier
] that used
V-USB
, a library for implementing USB on AVRs. The entire circuit was done freehand and crammed inside the netbook. He says that it is a lot easier to see notifications, even when the laptop is shut.

Even designed a PCB with all smd parts to make it fit inside my eeePC (which has less space than blairs 901, mind you).Have I done something bad to hackaday without realizing it, or why am I ignored, my work denied?pheeeee……http://eeegadgets.blogspot.com/2009/07/usb-mail-notifier-final-revision.htmlhttp://forum.eeeuser.com/viewtopic.php?id=69849&p=5http://sourceforge.net/projects/dbirdnotifier/files/Can anyone tell me,WHAT A HECK AM I PUBLiSHING OPEN SOURCE IF NOONE RECKONS MY AMOUNT OF WORK I PUT INTO IT; may it even be as small as a short “made possible through some software written by dennis” or sumthing..But why publish open source at all if I get no credit?",

[Maarten] told us about a
C64 USB keyboard
that was modified to be used as a standard input device. An interesting aspect of the project is the
use of V-USB
(formerly known as AVR-USB). V-USB is a software only approach to slow speed USB HID. In essence this is a two fold mod, The C64 keyboard is patched to a PC, and an off the shelf AVR is software-hacked to bit bang the USB communications. The author notes an initial problem with multiple key presses that was later corrected in the application. For the other side of the spectrum, we had covered the
C64 twittering client
, and a
commodore 64 laptop
.
