We haven’t made a regular habit of watching BoingBoing TV, but lately they’ve been covering topics we’ve been interested in… not the dolphin pr0n. In
yesterday’s episode
they talked to Jacob Appelbaum and members of the EFF about the
cold boot encryption attack
. The attack involves dumping the contents of memory to a storage device by power cycling the system. Cooling the memory chip with compressed air helps preserve the integrity of the data. The attacker can then search the data to find encryption keys protecting the contents of the hard drive. A fool proof solution to mitigate this attack hasn’t been developed yet. You can
read more about cold boot attacks
at the Center for Information Technology Policy. The BoingBoing TV episode, bizarre editing and all, can be
downloaded directly here

It also continually rewrites the crypto keys, xoring them each time, so they don’t build up a charge that can be recovered even after they’ve been wiped, and the chip itself is designed with its interface to the board practically unavailable by putting the data pins inside a perimeter of sense pins in a BGA.Other companies have similar things — and this is stuff being sold on the open market.

"content": "There are simple ways to defeat this, and although not 100% reliable they are pretty effective.You have to consider what sort of situation this attack is likely to be used in. The attacker would have to get to the machine while it is powered on, but be unable to access it due to software security (passwords etc). So, they reboot the system and try to recover the encryption keys from RAM.Why would you need to freeze the RAM if you could just hit the reset button? Well, the reset button might be disconnected, or the BIOS might be set up to do a full memory check which would overwrite every byte in RAM. The only way to be sure to avoid the BIOS wiping RAM would be to power the machine off, reset the BIOS and power it back on. Note that in laptops, even resetting the BIOS (which is typically very difficult as it involved opening the laptop up) often does not clear the power-on password.So, the attacker wants to freeze the RAM and put it into their own machine for reading. It’s going to be hard to freeze it, transport it to the new machine and install it without data loss, but for arguments sake let’s say it’s possible.Most machines have a case open switch, which could be used to trigger a memory wiping program. Assuming the program was intelligent things like encryption keys could be erased in nanoseconds, and the entire RAM in a few seconds. The attacker would have to power off before opening the case, increasing the time before they can freeze the RAM and thus increasing data loss.Really, this kind of attack, assuming you are reasonably well prepared for it, is not particularly effective. For anyone worried about law enforcement, setting the BIOS to do a full memory test and setting a BIOS password is enough to prevent it in most cases. An improvement would be to make sure your BIOS does a full memory test by default (i.e. after being reset). Some mobos do that, if yours doesn’t a BIOS editor might fix that.",

[PKM] decided to
breathe new life
into a Psion 5mx handheld. He slapped
linux
on it, added a wikipedia dump to a CD card, and voila: pocket wikipedia. It’s the closest thing to an actual hitchhikers Guide to the Galaxy I’ve ever seen. So long and thanks for all the fish!

Charter Communications
seems to be
pulling some sort of crap with their DNS servers
. While working on a new project our friend Billy Hoffman, discovered that Charter was reporting absolutely every domain as resolving. They do offer a solution by
providing an opt-out cookie
, which isn’t useful at all if you’re not using a web browser… and I’m guessing most of Charter’s subscribers aren’t looking for a bastardized version of the net. We’ve seen recently that messing with DNS like this can actually
open up new security holes
.

Totally unfriendly in reality when you try to do anything out of the ordinary-Its actually a Windows VPN client oddity – ISP DNS lookups are still performed whilst connected to the VPN (to Microsoft ISA server at least), arguably normal behaviour.So its important for ISP DNSs to fail unresolvable lookups normally, so that they are instead failed thru to the VPN provided DNS (our internal DNS servers). That way, staff can resolve addresses internal to our network (not exposed on the internet).Either way, without this oddity, it just wouldn’t be an issue. Typical MS really.",

XBMC
(formerly Xbox Media Center) has always been a popular choice for
retiring an original Xbox
. Maybe people install it for lack of something better to do or maybe it’s the pride in having better media support than the 360. The XBMC team has found another device that has a pretty weak television experience, the Mac.
Lifehacker took the latest XBMC for OSX beta build for a run
now that it supports remote controls. It seems like a much more functional than Apple’s built in Front Row. There are a few things that don’t quite work yet, which you can
find in the FAQ
. We’re definitely going to try this on our old Mac mini… once we upgrade it to Leopard, which is an unfortunate caveat that might prevent people from running XBMC on legacy hardware. There is no Apple TV support planned because of limited horsepower and the hacking hurdles that might be required. If you’re interested in repurposing your old Xbox with XBMC, check out
Lifehacker’s install guide

Smart Car Sensing With RF
|

[

[] |
In order to tell his home automation system that he’s home, [Jim]
mounted
a RF transmitter in each of his cars. When the car is on, the transmitter is powered up. The house picks up the transmitter signal when the car arrives or departs. With that information, he was able to set up some stateful rules that can be activated when people arrive or depart. Some people prefer to use
APRS
and read vehicle location from the transmitted GPS coordinates, but this is a bit cheaper and doesn’t transmit your position to the entire world all the time. The useful range is about 100 feet, so this can work even if you have to park in the street.

Human Sync Optical Tachometer

[Jared] sent in
this
optical tachometer by [Mike Freeman]. The write-up and code requires a free registration, but if you’ve got a use for it, it’s probably worth the hassle. The zip archive includes a nice writeup in PDF format, and the code needed for the pic controller. The tach was built specifically for model helicopters. The user looks through the viewfinder and adjusts the pot on the side until the spinning helicopter blade visually stops turning.

Yes, even we were getting tired of that Indiana Jones marathon on TV. So, we ventured online to find something entirely too geeky for a Sunday afternoon.
The Future of the Internet and How to Stop It
is a presentation Harvard Law School professor Jonathan Zittrain gave at Princeton near the end of March.
He begins by covering early 20th century “sterile” technology like tabulation machines that were rented by the census bureau. The machines didn’t encourage any sort of innovation. Next he talks about “generative” technology like the internet and modern OSes where anyone can build whatever they want. The final step is the more recent move to what he calls “tethered” technology. These are the systems with upgradeable firmware where devices can ship with unfinished features and remove features after the consumer has already purchased the device. He uses the iPhone as an example of this walled garden that could hurt innovation. Watch the video for his thoughts on this new world and how he thinks it could be fixed.

This week’s How-To comes from our newest contributor: Logan Williams.
This simple guide will show you how to build a digital synthesizer that generates and manipulates square waves. Your synthesizer will have one oscillator, which produces a variable pitch controlled by a potentiometer, as well as an LFO which modulates that pitch at a variable frequency. The part count for this project is quite low, and it can be built for under $20.
Finding the Parts
The first step in building this digital synthesizer is to
procure the parts
that you will need. Most of these can be bought at
RadioShack
, but RadioShack’s prices are often much more expensive than ordering online. All of the parts for this project can be purchased at
Jameco
,
Digi-Key
, or
Mouser
. We’ve provided Jameco part numbers below. If you don’t mind waiting, this is the best way to order parts.

Note
: The potentiometers and audio jack must be either taped or soldered to 22 AWG solid core wire.
Soldering
is highly recommended, as it produces a more secure connection.
Creating an oscillator
Before we can begin with the digital synthesizer, we must generate the correct voltage. Most of you will be familiar with using a 7805 5V voltage regulator. It is very simple; connect the +9V from the battery to the left hand pin, ground the middle pin, and the right hand is +5V.
The most basic circuit in any synthesizer is the oscillator. A square wave oscillator constantly alternates between two voltages, in this case +5V and 0V. We have a logic inverter to create this, which operates quite simply; if it is given +5V in (a logic 1), it give
s 0V out
(a logic 0) and if it is given a logic 0, it gives a logic 1 as output. When the input and output are connected together, it will oscillate rapidly between those two values: a 0 goes in, comes out as a 1, goes in, comes out as a 0, and so on.
The problem is that it oscillates much too fast. A resistor capacitor (RC) delay circuit can be added to slow it down. This forces the output current to charge the capacitor before it can pass through to the input. The resulting brief delay slows the oscillations to audible frequencies.
To build the oscillator, assemble the schematic below on a breadboard.
When done, the oscillator should look something like this:
Connect one side of the audio jack to 0V and the other side to the output, and it will sound like this:
Controlling the oscillator
We can make things more interesting by allowing the user to change the frequency. We replace the constant resistor R1 with a potentiometer, such as the 100K R2. This is a simple change to do, and is reflected in this altered schematic.
Now the oscillator sounds like this:
Much more interesting. Try playing an actual song, if you dare.
Duty cycle adjustment
We can add some basic timbre control to make the oscillator more interesting. The duty cycle of a square wave is how long it spends at logic 1 vs. at logic 0. For example, a wave that spends 1 ms at +5V and 1ms at 0V per cycle would have a 50% duty cycle. 1.5 ms at +5V and 0.5 ms at 0V would be a 75% duty cycle. To adjust the wave’s duty cycle, we can add another potentiometer and diode to the circuit. When the input is high and the output is low, current will be able to flow through both potentiometers, decreasing the amount of time it takes to charge the capacitor, and increasing the duty cycle.
It should sound like this when completed:
Creating an LFO
A low-frequency oscillator (LFO) is an oscillator that oscillates very slowly, from 1 to 100 cycles per second. We will use an LFO to alternate the pitch of our oscillator between two different frequencies. This can be used for siren like sound effects, timbre control, or musical sequences.
The circuit to control the LFO is slightly more complex than the ones we have used before. Because it uses a capacitor with 10x the capacitance, and a potentiometer with 10x the resistance, the oscillations are 100x slower than our first oscillator. The LFO connects to the gate of the IRF 510 MOSFET transistor. When the output of the LFO is +5V, the transistor connects its source and drain pins. With these pins connected, current can flow through the second potentiometer, increasing the pitch. When the LFO returns to 0V, the potentiometer is disconnected, and the pitch drops back to its original level.
There are quite a number of sounds that can be produced with the LFO, such as this:
and this:
Conclusion
You have now made your own simple digital synthesizer. Keep experimenting with different control methods. The frequency is adjusted with just resistance, so almost anything can be used for an input. Try a
photocell
, or a
flex sensor
. Try combining the LFO and the duty cycle adjustment. Try using it to actually make music! We’d love to see what you come up with.

At what point do you measure the temperature and how fast does it react to an ambient change? All things you can deal with but count on many spins and a lot of ‘burn and learn’ code.2. Failure mode. This is the big one. It would sure suck to come home and find your temperature set to 120. You can imagine a lot of possibilities here.I know this because a few years ago I thought “I’m going to build a power stealing programmable communicating thermostat” and I did. After a TON of work, it worked almost acceptably, but I scrapped the project when I realized it could burn down my house.",

[Ryan] sent in [Bill]’s
project
to build his own JAMMA arcade game console. It’s actually a take off from one of [Ben Heck]’s
how-tos
, but I thought it might interest people who think that they can’t pull off any of the projects we feature on their own. We definitely like to show off some original, complex hacks, but success stories can be just as inspiring.

[Yuri] spent some time building a computer controlled, arduino interfaced beer brewing rig. A cooler serves as a mash tun, while the arduino controls a steam source that’s used to raise the temperature of the mash as desired. A java app talks to the arduino to set the temperature parameters and monitor the steam boiler. You can catch a nice
video walkthrough
of the setup, see some
screen shots
of his java interface.

Your “mashing-in” the grains to have enzymatic activity that converts the starches to sugars. Alpha- and Beta-amylase each have their own preferred temps and they produce a certain amount of ferementable sugars.But, too much heat/water(rise in ph) causes tannin extraction resulting in bitterness. Hence why Yuri’s automation is so neat! It controls both with precision.Now if any nerd can’t appreciate the chemistry behind the beer making and the neatness of Yuri’s automation, then I just feel sorry and would love to offer a homebrew to change your mind.",

, it’s like getting a Christmas present and a night off. He put together a whiteboard, x/y stepper system, serial interfaced microcontroller and added a webcam with perspective correction for the online view. Me? I’m tempted to build one of these for leaving notes for the wife when I’m out.

This one’s
In honor of my
new project bike
. [wildwestsyndey] converted his Suzuki DR 350 from the stock carbs to EFI using the
megasquirt
EFI controller and a custom machined throttle body. You can find a few pictures of the conversion
here
. To handle the ever annoying need for a high pressure fuel pump, he adapted an in-tank scooter pump with a machined mini-reservoir to fit in-line with the original tank. For more motorcycle builds, check out the megasquirt
success stories forum.

Certain OS installers cough*osx*cough don’t like the on-board displays on some machines. [Ziddan]
posted
a paperclip based work around for them on the eeeuser forums (originally posted by [mugan] on insanelymac). Apparently by shorting the pins, the video card will report that there is an unknown external display attached.

Friend of Hack-A-Day, [Dan Kaminsky], started off last weekend right by putting Rick Astley everywhere on the internet. ISPs routinely hijack mistyped URLs and [Dan] showed that an attacker could
inject code into any unresolved subdomain
, essentially taking over every site the ISP’s customer tried to reach. I doubt many companies would be happy to know their websites were being misrepresented.
The week wasn’t going so well for another friend of ours as he found himself back in court for allegedly
inventing the entire satellite piracy industry
.
BoingBoing TV
featured the Graffiti Research Lab
this week as they prepare for the
New York premier
of GRL: The Complete First Season. GRL encourages you to
pick up your copy today
… before they’ve even started selling it.
While you’re over at The Pirate Bay you might as well ask them where to get the
leaked copy of Grand Theft Auto IV
… or you could just wait a few days and buy it like a normal person. We do recommend you bide your time by checking out the
GTA 4 leaked gameplay videos
,
GTA 4 walkthrough
, and
GTA 4 cheats
.
Don Hodges has been carefully analyzing an patching old arcade games to fix their
kill screens
. His latest fix was
Ms. Pac Man
, but he’s fixed
Pac Man
and
Donkey Kong
previously. [via
Waxy
]
We know most people prefer Rock Band to Guitar Hero, but has it really gotten so bad that only robots play it now? Just this week alone we saw both
AutoGuitarHero
and
Slashbot
[via
Hacked Gadgets
]. Of course, doing that one useful thing makes them completely ineligible for Japan’s
Annual Stupid Robot Contest
[via
Neatorama
].
Finally, for all of you that have trouble interacting with other organisms, here’s An Engineer’s Guide to Cats.

That sort of thing only belongs in certain contexts, most of which are in the back of a volkswagen bus parked in the middle of nowhere….etc. Out of context, it’s just a bit awkward.i feel somewhat the same way about posting that torrent link on this site. a site i like very much is torrentfreak.com. that link would belong on that site and it would fit very nicely at the bottom of a nice informative article about the leak.totse.com is where i would go if i ever needed rob/ murder/ rape someone and wanted very bad advice on doing those things. discussions of drug-use and (come to think about it) pretty much anything law-breaking-related would be relevant and expected on that site.i’ve never been pressed to find out really, but i’m sure there’s plenty of sites out there that revolve around graffiti or “street art”. grl comes to mind because that’s often linked to on makezine, and i think they are completely legal and high-brow in their actions (not sure?), but even a discussion about more shady graffiti practices could take place there because it’s relevant somewhat. (slightly off-topic, but I think it’s strange that a lot of the same hippies who build things out of bamboo to be “ecologically friendly” tape up batteries, leds, and magnets and throw them all over the place…*cough* makezine *cough*)hackaday.com is about hacking (choose your favorite definition). if some major software is leaked before its release and mentioned on hackaday, i want a discussion about how this was done, how it could be prevented, or a link to an article elsewhere with that discussion. just linking right to the illegal part gives a bit of a bad image.I love this site, and I’ve been reading it from the beginning. i am sure elliot didn’t mean anything bad when he posted that link, but if an outsider read that part, it would be far too easy for them to take for granted that we’re all a bunch of game-stealing kids. i am sure it’s very hard to find great links, write great articles, and please everyone in the world (in your free time), and i hope this comes across as not-unfriendly feedback from an avid reader and fan.",

We saw a lot of interesting gear at Maker Faire last weekend and thought we’d highlight some of those projects this week. [Josh Boughey]’s
Stribe
was originally inspired by the
monome 40h
. It features of 16 columns of 64 LEDs for a total of 1024 individually addressable lights. Even with all those LEDs, PWM control means it can run off of USB power. 8 spectrasymbol
softpots
are used between the columns for user input. It’s really quite an amazing feat for being [josh]’s first board design. All of the circuit designs and firmware are available. Check out Flickr for
more photos from this weekend

I was starting to wonder when [Bruce] would send in
this years final projects
from the Electrical and Computer Engineering students at Cornell University. The
first project
looks like a great one for the green geek – a controllable power usage monitoring power outlet. The music geeks should dig
midi trumpet interface
, but the car geeks might have problems keeping away from the soldering iron after they see the
CAN bus SD card data acquisition system
. There are plenty more, so go check
em out

A while back, [Phil]
got ticked off
and started working on linux support for the Logitech Harmony remotes for quite a while. Having owned one of these sweet remotes, I can honestly say that yes, they rock, and yes, the driver software can be pretty freakin’ annoying. If you’ve got a Harmony remote and would like an alternative to the usual fare, check out
[Phil]’s project

Even better is I was able to setup macros to do do things like dive into the projectors menu to change the aspect ratio and color profile so now I can run different configurations per device, something that was just far too time consuming to be practical in my previous setup.Even better is my fiancee is comfortable using it without my help and I’m comfortable with her using it through the remote.I only have 2 real gripes, 1 is that it’s IR and occasionally someone will walk in front of the remote and it will get out of sync, but this is my own fault for not buying an RF model. My other gripe is that the programing software will not allow you to set the order of certain devices.If this hack fixes my #2 gripe I might be include to dual boot Linux just to use it (I’ve been debating setting up a Linux install anyway)",

I’ve never owned a piece of equipment that doesn’t already have all the IR codes pre-programmed, and I’ve had only one device where the original IR codes were crappily recorded.A bigger bonus is that I don’t have to set up the screens. Creating tedious little boxes here and there, deciding which buttons are “universal” and which ones I could do without, deciding what to stick on “screen 2” or “screen 3”, all that is gone with the Harmony. Sure, I could go back and change all the buttons, but I don’t have to. I’m paying for the convenience of the remote, I want the convenient setup to come along with it.My only complaint, though, is not with the Harmony I bought to make my father-in-law’s life easier, but with his new Samsung television. Selecting input on the Samsung is beyond ridiculous. If you’re not in antenna mode, it won’t let you switch to the tuner by pushing the tuner button — it gives you a freakin’ error screen like some lame windows program! It lets you switch away from antenna mode, but not back to it. That does not make programming a Harmony easy.",

Add Bluetooth Audio To Your GPS/etc

[sudija] wrote up a nice
instructable
on adding bluetooth audio output to a tomtom gps unit. It’s not too technically advanced, but you’ll have to add an audio jack if your gps lacks one. This looks like a great way to turn a cheaper unit into something suitable for a motorcycle rig.

Hackit: Ironman/movie Inspirations?
|
Will O'Brien

[
"HackIt"
] |
[] |
I got a chance to see the new Ironman movie last night, and it’s exactly the kind of film that kick-starts my brain into considering new projects. I’m opening up today’s hackit in a few directions:
1) Get any project ideas from Ironman?
2) Got any projects that were inspired by movie/tv/comic tech?
3) What’s your favorite source of inspiration?

I love mechanical simplicity, so relying heavily on computers just feels unreliable to me.I’ve also been dreaming up designs for simple strength enhancement exoskeletons for the arms. Similar to the arm he is working on in the movie, but so far I’ve only tackled movement in one axis. I”m studying engineering, so its good exercises to just come up with these solutions, even though I’ll probably never build them unless I learn more about circuits.",

If you try to bend/flex your arm f.ex., you push against a sensor and the “suit” takes the corresponding action. The force the suit applies (and the speed, of there is little or no resistance) depends on the amount of pressure you apply to the sensor.

Solar Lamp To LED Projector

Despite the resemblance to an alien robot that might rebuild your house from scratch,
this
is actually the first mod for a solar yard lamp that I’ve seen. By adding a brighter LED, a couple of tubes, a laser printed transparency and a lens, you end with with a relatively inexpensive image projector that can project custom graphics from odd locations. [

There’s nothing quite like a nice, simple hack.
This
serial servo controller uses a PIC12C671 and a pair of resistors. Leaving out the power supply, that’s the lowest part count I’ve ever seen.

When I built
my
LumenLab projector, I used a thermal switch to run the fan.
This
simple control circuit looks like a nice alternative. The circuit is a simple adjustable temperature triggered Fet. If you know the resistance needed, you can replace the potentiometer with a cheap resistor. (You’ll want to use a DC fan)

[Janne] does freelance animation and wanted something with
a bit more CPU
to get his rendering jobs done. He picked up an Ikea ‘Helmer’ cabinet and refitted it to hold six Intel quad cores, six Gigabyte motherboards with 8GB of ram each and six 400 watt power supplies. He seems happy with it – I think it just needs some custom power wiring and an integrated Gig-E switch to achieve perfection. What? I’m not jealous at all.

[everett] sent in
his
final project for his mechanisms class. In an attempt to create his own bolt on X gene, he built a wrist mounted hand activated flame thrower: The Pyro System. The wrist mount has an igniter and a nozzle for dispersing fuel. When he flexes his hand back, a switch actuates a servo on the fuel and fires the igniter. Quick disclaimer: Don’t try replicating this one! If you want to skip the movie clip, skip 33 seconds into the video.

The method of extinguishing the flame is counter-intuitive. There’s no shielding between flame and hand. The positioning of the flame, while cool, in echoing that of Pyro, shields it from the user’s line of sight.As to jealousy ?

The second ToorCon Seattle got off to a quick start last Friday with a round of
Lightning Talks
at the Public Nerd Area. Each talk was limited to 5 minutes and covered a broad range of topics. Some talks were just supplying a chunk of information while others were a call to action for personal projects. Here are a few of the talks that we found interesting.
[I)ruid] opened with an explanation of his handle, since he catches a lot of flak for it being l33tsp34k (that’s supposed to be a capital ‘I’). The name has actually proven to be quite fun since it has broken a few systems that aren’t sanitizing input properly. Registering at Black Hat 2006 caused a database error. At the ShmooCon hacker arcade, he entered his player name and was dropped directly to a root shell. It’s also rather hellish on many webapps. His point was: why not choose a l33t name and have the fun of fuzzing all the time and breaking stuff even when you aren’t trying?
[nous] gave a quick plug for Ninja Network’s phreaking contest. Last year at Defcon was the first event they held. The first task was to use a
butt set
on a 25 pair block to find usable line. Once the random line was found they were dropped into a voice mail system to explore. The backend for the contest is
Asterisk
plus some custom Perl scripts. You can catch a preview version of
this contest next month at LayerOne
.
[jrandom] talked about how scratch-off cards can be gamed. Using a bright light or a resurfacing pen can help you with games that require a certain scratch order. Other cards can be identified by telltale signs they pick up during their production. Winners and losers are usually produced in two separate batches. Cards from each group will have the same cut quality, alignment flaws, printing color, and even the font could change. Sometimes the cards even have coding on them to indicate the winners (could be a simple as a W and L). All this is great, but the manufacturer might be doing this intentionally just to get attention.
[Travis Goodspeed] gave a brief introduction to reversing the
Econolite ASC/3 traffic light controller
for compatibility. It’s a PowerPC box running VxWorks 5.x and has snmp and FTP support. The FTP provides simple anonymous access. All of the control values are stored in the ASC3.DB binary file that’s checksummed. [Travis] built a way to
describe a binary file structure as XML
and generate libraries for reading the binaries natively in multiple languages.
We also thought [Dean Pierce]’s
network pentesting visualization framework
was interesting. [Joel Voss] was attempting to write a softphone for the IAX2 protocol and ended up DOSing Asterisk. 30kB from the attacker could cause a massive amount of packets from Asterisk. He now has a
framework for testing all aspects of the protocol
.

[CyberPyrot] and [l0rdnic0] released their
spitfire mod
on acidmods for XBox 360 controllers. It involves some fine wiring, but a relatively low parts count. The heart of the mod is a PIC16F84A, a crystal for the clock and a few passive parts. It took me a little while to find it, but the code for the pic hiding under the parts list. For a lengthy demo of the mod in action, you can check out this
video

The old controllers did NOT use a typical common ground setup but rather this weird pulsed matrix system (presumably to reduce the internal pin count).

[
Gabriel
] put together an impressive writeup of his autonomous catamaran,
Atlantis(PDF)
. It was certainly done as an academic project, but there’s a thorough explanation of the math logic behind the control systems. The heart of the boat was a waterproofed Pentium laptop with a CAN bus parallel interface used to talk to everything on-board. Sensors included GPS, wind, hull speed and rudder angle. In case the site can’t handle the load, I’ve mirrored the 1.4MB PDF
here

[Nick] sent in this sweet midi pedal organ. [Seffan] modded an old set of organ pedals with the cheapest midi keyboard he could find. Each pedal was equipped with a switch mechanism, so it was just a matter of patience and wiring. To come up with enough wire for the job, he sacrificed some IDE cables. If you’ve ever played with some organ pedals, you know that these things can really add another dimension to music – especially with the newly added MIDI interface.

Sony XEL-1 OLED Teardown

[bunnie] just happened to be at the Embedded Systems Conference in San Jose on exactly the right day to witness the live teardown of a Sony XEL-1 OLED TV. The XEL-1 is Sony’s flagship OLED panel that’s only 3mm thick… and $2500 for just an 11-inch screen. [bunnie] was able to take
quite a few shots of the components
as they were passed around. He pointed out a few interesting bits about the construction. There seems to be quite a bit of thermal material on the display to prevent “avalanche thermal failures” (which I’m guessing doesn’t look as cool as it sounds). OLED displays are completely transparent and their legendary contrast ratio is just a result of the dark backing material. The mainboard seems to be a bit of overkill for this TV and [bunnie] concludes that it’s just the standard image engine architecture from Sony’s Bravia line put into a smaller package.

But more work needs to be done on creating thinner circuits for the drivers.If SONY just left off the *shell game* of “Look at how thin it is!” from their promo hype (hence inflated price driven purely by marketing) the world would be a slightly better place. It is an insulting marketing ploy. How thin would LCDs be if you moved all of it’s electronics to a huge base station? My laptop screen is pretty darn thin, too.I predict the XEL-1 will flop because most people just aren’t that stupid. Hopefully OLED TV technology survives it, though.",

Got a bit of a pest problem? [Chad] built a
better squirrel/rabbit/thing trap
using a soekris box, a laser pointer, serial controlled relay and a small motor. When the laser beam is broken, the Soekris activates the relay, pulling the door pins. Then it take a picture with a webcam and send him a page.

Joe
] sent along
this
sweet little instructable on making an electric skateboard. I like this one especially for the how-to nature of the build. [Vurp] used an off the shelf mountain board with a brake addition, a 300w scooter motor/controller and a pair of 12v SLA batteries. Now that I’m
back on campus
, I might just be tempted to build something along these lines. Just in time for this electric vehicle post, [Darin] sent in the

I just got back from the shell eco-marathon in California, and we had a solar car that kicked some major ass at the competition. their weird EV conversion factor put us at 2861 mpg, but the actual useful numbers was the fact that we pushed a 158 lb car with a 120 lb driver at around 15-16 mph, using around 170 watts. This was also with 20 mph crosswinds and headwinds, and gusting to around 50 mph. It was powered off of 3 small lead acid batteries (couldn’t get the li-ion pack working right), so basically a 36v system with 7.2 amp hours.Now that the long-winded explanation is over… As long as you have good starting torque, the power consumption isn’t a problem really. regen would be easily doable, and a quick charger could probably get it charged in under an hour of plug-in time. We had about 3 m^2 of solar cells (only 20% efficient, though), and it was just getting enough to get us into the positive power range. So for the solar case, adding a few cells won’t run anything save for some control circuitry. a charging station is a much better idea.",

I may hit my limit on DIY laptops soon, but [Ben Heck] has been extra quiet for a while. Now we know why. Just after the release of his
PS3 laptop
comes his
Apple IIGS laptop
. Thanks to [Ed] for the tip. It features original Apple hardware and even uses the original keyboard PC board. A CF drive adapter replaces the hard drive and a 15 inch screen shows off the true power of 8 bit computing.

Remember the voltage detector that I mentioned a while back? [Tim] hasn’t put up quite enough info to make me happy, but definitely enough to make me jealous. He
updated
his NES controlled Silvia to become a Wii nunchuck controlled (via Arduino) Silvia. That said, his last couple of blog posts have me questioning just how much espresso he’s been drinking. Theoretically, he could actually program the Silvia to refuse shots to people who are too jittery.

I was considering a laser cross-hair for my mill and found this video of some great setup hacks that [Greolt] put on his mill. The video is pretty short, but I’ll fill you in just in case you don’t want to play/load it. A laser cross-hair is mounted at a known offset to align the X and Y axis. A PC board is wired to a sensor to zero in the Z axis. When the bit makes contact, the machine knows that it’s at 0 + the PCB thickness. A shuttle pro controller adds jog controls and a macro takes care of moving the bit to the zero that was measured with the laser cross-hair. You can find more details on his zero touch setup

Dual Core… Arduino?
|
Will O'Brien

"Misc Hacks"

[] |
[John Ryan] posted his dual core Arduino rig on the
Arduino forums
. These two ATMega168 chips share the same 16Mhz resonator and I2C bus – allowing them to run in semi-parallel. The uC’s don’t actually communicate with each other, but they run rather nicely as concurrent circuits. It’s a pretty interesting method of adding I/O pins to a project for a minimal cost.

"content": "He wired the chips in parallel – this doesn’t seem to be a good idea. Resonators are usually driven by a not gate – one pin is an input, the other is an output. It’s wired so that the two outputs are driving each other — bad practice! This will waste energy and stress the parts. It’ll also create a lot of electrical noise as the power supply is repeatedly asked to supply the short circuit current every oscillation.The better solution is a master/slave setup. One device will control the oscillator (connect XTAL1 and XTAL2 as usual) – this is the master. The other device is set up in “external oscillator” mode, with its input driven from the first. I looked at the spec sheet quickly, and it looks like XTAL2 is the output and XTAL1 is the input – this means you should connect XTAL2 of the master to XTAL1 of the slave. (you can verify this with an oscilliscope – the output waveform should be the squarer one)—On another note, I’ve thought it would be fun to take a 10 x 10 array of these tiny 100 MHz processors and make a 10GHz-equivalent computer on a 4×4″ pc board:http://www.silabs.com/public/documents/tpub_doc/dshort/microcontrollers/small_form_factor/en/c8051f365_short.pdfbut, with limited communication, it could only run certain apps well.",

The Software serial library also took another year of developing before it became a viable alternative. This hardware solution is still by far the best and cheapest solution for increasing the number of USART’s for your (hobby) electronics project.Dual USART is accomplished using a switch between both processors allowing either chip to be selected for programming. The two chips then communicate using the wire library, and the board I designed and manufactured has the i2c lines etched in with two inline 1.8k resistors. A sketch can be designed to run on one processor which utilizes both USART’s, or two sketches can be run that share USART device data.@morcheebaI had several dCore boards running for over a year (on and off, 7 days was initial constant trial period) and no problems with parts failing. Others that received boards reported no issues either, the processors remain syncronized and didn’t over-heat, cook, fry, cry, or burnout.I also tested two RBBB’s and the power consumption was more or less the same as the single dCore.So “if” your info is correct, then none of the characteristics you described presented themselves and that’s probably because the scale of the characteristics you described are inconsequential.@LupinIf it were as easy as joining two bulbs then I wouldn’t still be getting requests to this day from people asking for a copy of the sch and brd files. But it’s nice to minimize other people’s accomplishments, especially ones that are so conceptually simple that your kicking yourself for not having thought of it first.Now I have a 328 version in production. That board will be shield compatible. The boards are for “my own use” as were the 168’s, and if someone has an issue with the concept then I suggest you invent your own better solution.",

an interesting looking gaming gun for FPS games. He wrote up his build and how to use a webcam to provide gun tracking for games like Half Life 2. He gutted a keyboard to provide the button interface, and infrared LEDs on the gun body are tracked by the cam. Surprisingly, no USB game pads were sacrificed in the build, just a USB keyboard and mouse.

[Ben]’s been at it again. This time he’s whipped up a PS3 laptop. He built this one just for
engadget
… and there will be how-to’s on it, oh yes, there will. For now, you can wet your appetite for console modding with
the picture gallery
. It’s pretty big, but It’s actually thinner than the original console.

It’s true, as much as [Will] and I like being a scrappy two person shop with a ‘never say die’ attitude, and penchant for fist pounding after successful compiles, we need more people (MOAR even). We’re looking for a few more contributors to help out with the daily posting, digging up the extra obscure, and especially the how-tos we’ve started to get back into.
This is a paid, freelancing position that requires professionalism, consistency, and reliability. We want to hear from people that are passionate about software/hardware hacking and growing Hack-A-Day. To apply, send the following to jobs@hackaday.com
A short bio about yourself
3 example daily posts written in the style of Hack-A-Day
3 how-to ideas you could personally execute. For examples of work we’ve done in the past, look
here
,
here
,
here
, and
here
.
A couple sentences on how you would improve the site either through features or content
Any additional reasons why you would make a good fit for Hack-A-Day
Please do not send any attachments, especially not pictures of your sweet ride. An aversion to capital letters is not required, but definitely encouraged.

I only wish I tinkered more so I could feel justified in applying. so sad.Piping in and dropping my 2 cents even though no one cares:Colors and Site Design — I miss Kermit, so green and black strike me as fine. OK, so I don’t really miss Kermit as much as having a soft spot for green and black. Between Opera being able to load style sheets and the above grease monkey script, it’s a moot point though. Anyhow, green and black is built into hacker/cracker/phreaker/etc history.Newbie section — For 98% of the stuff here, the only really basic topic needed is getting the parts and putting them together. You have an article on getting parts and soldering already. Past that anything people consider “basic” is going to be too basic for some and still too advanced for others. Instead of an entire newbie section, I’d think that a single article guiding beginners to appropriate beginner level resources would be far more useful. Making it a live article and occasionally updating it with a quick mention in the day’s post wouldn’t be that difficult either. Plus, if the site is recommending books, retailers, and what not I doubt many would mind at all if you got referral credit for sales and what not (For those retailers that offer suck things).Other random ideas for people to steal when they apply (or to knock the easy ones out of the way to make them think harder :D)— Other DIY sites (toolmonger.com and strobist.blogspot.com spring to mind) maintain a flicker pool for readers to upload their projects and what-not to. Doing similar here would allow the reader base a chance to interact with each other as well as share works in progress that they are working on without having to do up entire articles. Interesting projects can easily be called out in the Short articles with a handful of links (which i miss)— To touch back on the newbie discussion, articles focusing more on work area set up than the projects themselves might work well within the context of the site and fit in when it’s a slow day for projects to link/write up. I know that there was the Hack-it Challenge, but more might be interesting.— Extending the Hack-it Challenges, low cost of entry contests might be fun. Thinking of the challenge itself might be difficult though. Only instead of the Hack-it, brainstorming format, this would actually require both conception and completion of the actual project. Low entry cost should make it easier for all to enter while letting those who want to spend more do so.It seems silly to suggest ideas in the comments since I’m not currently applying. Perhaps these will just get ignored, but, like i said, I wanted to pick off the low lying fruit.Good luck to those who do apply.",

Trying to figure out the best way to do that was a brief en devour of mine. Sadly real life concerns got in the way and I never wrote down specifications and have forgotten most of the ideas.However, “where advanced users can share ideas and help each other out with problems” matches what goes on the team hack-a-day forums. They formed around an unofficial folding team, but that is not all that goes on there, nor is joining the folding team a requirement. Scroll past the first block of sub-forums, and you get to things like computers and technology, and even CNC machine subforum.",

[3ricj] wrote up how to build your own
low temperature test chamber
to verify that electronics will function at the edge of the atmosphere/outerspace. He needs this for the
edge of space project
he’s working on. A large cooler serves as the test chamber. It’s cooled down to about
0c
-42C with dry ice, then a supply of liquid nitrogen is fed into a copper heat exchanging coil to bring the chamber down to -70C.

Chumby Hacking By Bunnie

[bunnie] is one of the main people behind the Chumby, and even he can’t resist modding the things. He decided to outfit one with a
larger LCD
– using a stereo microscope to do the really fine pitch work – and a laser cutter to create a custom bezel for the finished piece. The new LCD is still a touchscreen and allows the Chumby to display 640×480 resolution over the stock 320×240. The mod requires a few parts, but the ultimate difficulty is caused by the surface mount connectors. If you’d rather have some software fun, you might want to check out [bunnie]’s Chumby
wifi sniffer

Nate Graham
] gave a presentation on what he considers ‘new media art’, the convergence of art and technology. He covered quite a few great examples of what new media art is from many categories: a mower that
creates pixel art
, Cory Arcangel’s famous
Super Mario Clouds
hack, a whale hunt whose photo capture rate depended on
the participant’s heart rate
, the
bike based SMS printer
for protests.
Non-places are areas that lack any history or monuments: a McDonald’s looks essentially the same no matter where it is. Like a hotel, supermarket, or airport it no one expects it to have any sort of historical significance to the local population. He had examples of how some of these spaces are being humanized. The project
We Tell Stories
uses a Google Maps hack to give a fictional story locational awareness.
GRL’s lasertagging
work turns single purpose items like bridges and buildings into giant canvases. There are even location based gaming like
Plundr
which gives purpose to spaces that are generally ignored.
The video above is Nate’s personal project ‘
Invisible Narrative
‘, adding a hidden story to a nondescript elevator car. An audience member asked if GRL giving away their techniques might increase the amount of annoying ‘guerilla’ ad campaigns. His response was that releasing any type of technology could result in people implementing it in a bad way, but it’s important to get free technology into the hands of people who will use it for good.

version from 2004. His team used a combination of MatLab, an Altera FPGA and sixteen pumps to produce real-time sound spectrum output.

[
Pete Edwards
] and [
Fred Owsley
] openly admitted that the title was the most thinly veiled audience-bait ever constructed. Nevertheless, they poured through a great talk covering the basics of
circuit bending
and some of the pieces they had built over the years. Fred said that what attracts him to circuit bending is the hands on approach to something very scientific i.e. he can figure out how to construct an interesting circuit by rubbing his finger along the back of the board. As far as where to start: always a battery powered device and use the toy store as a last resort. You’re going to tear the thing apart so why pay for it? Dumpster diving, garage sales, swap meets, and flea markets are all places to look. Parts don’t need to be anything better than grab bag either. They suggested an easy first step is dropping the operating voltage of your device and seeing how it reacts. Pete and Fred had several examples of devices they’ve modified:
Speak & Spells
,
Casio SA keyboards
,
Barbi karaoke machines
, and the
voice changing gas mask
pictured above.
The
Bent Festival
for circuit bending is coming up soon if you’d like to see more. You can also check out these links for more information on circuit bending.

I found this while looking for a teardown of a Wii Nunchuck remote since they’re cheap and include a
3 axis accelerometer
. I mentioned an interface board
the other day
, but the responsiveness of the interface in this video grabbed my attention. If you like it, you should check out
this
[
via
] Nunchuck Arduino RF controlled robot. You can find details on that bot
here
. The accelerometer itself only runs
about
$10, but it’s a pretty small SMD part.

[Mark Doner] presented on how the
WISP
he works for near Toledo is set up. His most important point was that 802.11 is garbage when it comes to the type of installations WISPs do. 802.11 expects the clients to adjust based on the traffic from other clients, but when all your clients are directional they won’t see each other. Mark uses
Motorola’s Canopy
equipment, but he also mentioned
Trango
and
Redline
as other vendors. The radios operate in the 5.7GHz band which doesn’t have any power restrictions so they can use refurbished Dish Network dishes when they’re doing long shots. For customers that are nearly at the edge of service, they have 900MHz equipment as well. Heavy fog and freezing rain have proven to be the only weather that really affects the service. For back-haul between their towers they use
Dragonwave
equipment. Each of the radios costs ~$350 and features GPS to determine distance and maintain sync with the AP. It was interesting to see how a good WISP operates as opposed to the flakey ones we’ve had to deal with in the past.

[algormor] gave one of the more controversial talks at
Notacon
. After receiving a few too many inspection slips and destroyed baggage he decided to find out what was going on behind the scenes. First, he purchased a cheap bag from Walmart with a zipable liner. To record the video, he purchased a
SwannGUARD MicroDVR
. It’s a palm-sized device that records 128×128 15fps video. It comes with a plastic cover that he mounted to the inside of the bag. A hole was cut for the video camera right above the badge holder. Since the camera is motion triggered, he could slide the badge up, covering the hole, to deactivate the camera. He’s taken the bag on at least four trips. So… what did the footage show?
Well, lots of conveyor belts, conveyor belts, and conveyor belts. Nothing really damning. It did show the the bag spend an uncomfortable amount of time in public after being checked and before security. It also spent time traveling through certain segments multiple times, being pulled off the belt for random periods of time, and then getting put back on. Audience members were concerned that he might run afoul of federal law because he was recording audio without people knowing. Surprisingly the bag has yet to be searched.

For the last month, I have set off 4 explosives sensors, and had my bag swabbed every time. I had no clue why my bag was triggering the sensors, and assumed it was some residue left on my bag after something I have done. Just this weekend I was coming home on a united flight, and carrying my T61, some cables and a box of business cards, and a terribly long roll of cat5 wrapped around the business cards (I know; terrible idea, but It was 4 in the morning when I rushed to the airport) It tripped the explosives sensor for the 5th time, and the box of business cards with 50ft of cat5 wrapped around it looked mighty suspicious to them. They ran the bag through the x-ray again and swabbed it. It passed, without even a search of the bag. While walking to the gate, my hand went to my shirt pocket instinctively which was covered by my backpack strap [which had a cellphone pocket on it]. The mystery of the explosives sensor was solved. I had 6 bottle rockets in the pocket. About a month ago this back pack was used to carry a but-load of fireworks, obviously spilling loads of gunpowder, and other explosives into the bag. I promptly tossed the bottle rockets in the next trash can.WTF, there was a legitimate reason I was setting off the explosives sensor. I never even had the bag searched. And its been through x-rays every time, what did the think long tubes [minus the stick somehow I broke them off and stuck them in the cell phone pocket] with fuses sticking out of them were?And even after my box of cards with wires wrapped around thema aroused suspicion they still let me go. I think the TSA’s strategy is not to sort out any dangerous people/devices, its more to intimidate you, with needless searches, and “ultra sensitive” machines, and numerous personnel. Now I’m not bashing the TSA, I am sure it prevents allot of “issues” that would happen on planes if we let everything imaginable on the plane, but it just seems that there technique is not methodical and straightforward, it is meant to intimidate. Something that just does not work, emotions can be overcome, There method needs to be methodical, so that we can actually remove what we are looking for.",

Notice the next time you go through that the only person looking at the X-Ray readout is one person. All the other TSA and security guards are looking at the faces of who are coming through. There is no way to be cool, calm and collected and be able to get through that place if you are trying to hide something. It’s the human condition.As for those that say there is no rhyme or reason to how and what they search: would you rather everyone know how they search and why they search certain luggage?

I know what ipods, batteries, adapters, books look like and I don’t need to search your bag. For some reaosn a lot of people think their electric toothbrush is the reason we’re searching the bag, it isn’t. Putting your bags through the xray doesn’t set off any explosive alarms, it’s just an xray and we’re looking at images. Gun powder doesn’t set off an alarm either, btw, otherwise all the firearms we inspect would be alarming everytime. What’s funny is that golf bags tend to set of the alarm because of the fertilizer used on the golf courses, hehe. So clean your golf clubs!Many servicemen as well as crew members get selected for extra screening. It has nothing to do with the TSA it’s just a weird thing that happens with the computer setup when they print your ticket. However, if you’re a serviceman on orders and in uniform, the additional screening is waived.Oh and none of us have any kind of “radiation alarm” and nails aren’t considered a weapon.",

The first talk we went to at Notacon was [
Sam Harmon
]’s great introduction to
circuit bending
, the process of modifying sound generating electronics to create new musical instruments.
Reed Ghazala
is considered the father of circuit bending for his pioneering work starting in 1966. Sam pointed out that a “
prepared piano
” could be considered the non-electric precursor to circuit bending. It involves the musician placing different types of material on the piano’s components. Sam presented many different examples of where to start with circuit bending: the
Casio PT-10
,
PAiA Theremax
,
Atari Punk Console
. He also mentioned a couple AVR projects:
AVRSYN
and
todbot’s Arduino work
.
The session ended with [Thom Robertson] showing off the
Weird Sound Generator
he built and his
GHX software
for playing real music with a Guitar Hero controller.

FRS Foxhunting For Model Rockets

"Misc Hacks"

Since we had a
FRS radio hackit
a while back, [Weirdguy] sent
this
in. [Scott] gutted a frs radio and added it to his rocket chassis. It’s powered on for the flight, and he can listen to the rockets progress. To locate the rocket once it’s on the ground, he built a 462Mhz
Yagi antenna
to use with a Radio Shack hand held scanner. This is old hat for most Ham Radio guys – they do ‘
Fox Hunts
‘ for hidden transmitters just for fun.

As one side of this FRS communication didn’t involve a person the FCC smacked the guy with a fine.The other FCC rules basically ban you from doing internal mods to an FRS radio, or boosting it’s output power / antenna gain.

[Matt] built
this
OLED display based clock for his electronics class. He used an ARM7 processor, designed a nice custom board for it and got busy. The clock face is actually a picture of the watch, and the hands are drawn on top as the time changes. Here’s to the first OLED project on Hack-A-Day.

Custom Mounting Manual Minolta/Sony Lenses

"digital cameras hacks"

We usually get
Canon mods
, but [polossatik] sent in
some
interesting Sony/Minolta lens modding work by [Shaocaholica], who’s been really been taking lens modding to a new level of quality. He picked up several old Rokkor F1.2 lenses and swapped parts around to make four decent lenses. Then he had [Pete Ganz]
turn down
some new mounts on his lathe. Finally, a quick round of epoxy to add a lens id chip activates the on board image stablization and focus confirmation. Be sure to check out the photo build log
here

The mod is also very easy to do, took me about 45 minutes initially, most of the time after that (can be hours) is spent adjusting the infinity focus position to desired accuracy (personally I wanted it good enough for astrophotography, which took more effort than most people need).As for the lens itself, the 58mm f/1.2 is a superb lens, perhaps the best bokeh of any I’ve seen. Not the sharpest, though, but for just sharpness there are so many others. Anyone commenting above about the advantages of “expensive glass” is missing the point entirely (plus that lens WAS expensive glass when new).",

This
is one of the most original April fools gags I’ve seen. [Garrett] sent in his USB caps locker. It’s built from an ATTiny45 and puts out an intermittent signal to set the caps lock key. Considering what day it is, it appears to be legit. After you’re done screwing with your co-worker for the day, you might be even more interested in the
easylogger project
that it’s based on.

We’re headed to Cleveland at the end of the week (we’ve heard rumors it rocks) and thought it would be good to list the events we’re planning on hitting in the next five months.
Notacon
/
Blockparty
April 4-6 Cleveland, OH – This will be a first for us, but we’re definitely excited, especially for the
demoscene
madness at Blockparty (like
Trixter’s MONOTONE
PC speaker tracker).
ToorCon Seattle
April 18-20 Seattle, WA – In its second year, this small gathering is sure to be a blast
just like last year
.
The Last HOPE
July 18-20 New York, NY – Our first HOPE and the last one ever.. since the hotel is being torn down.
Black Hat US
August 2-7 Las Vegas, NV – If anything gets released this year, it’ll be here.
DefCon
August 8-10 Las Vegas, NV – The first con we ever went to. It’s not the best con, but it’s always interesting.
SIGGRAPH
August 11-15 Los Angeles, CA – SIGGRAPH is where you need to be if you want to see cutting edge graphics and interaction projects. It’s a favorite of ours and a nice break from computer security.
Anything we’re missing?
UPDATE:
Maker Faire
May 3-4 San Mateo, CA – Can’t believe we forgot it. Thanks [pt]!

[Jared] sent in
his
experiment in building his own heated vest for motorcycle riding. He used some of the ever so common enamel coated wire and some surplus teflon tape in place of Teflon coated wire. So far he’s been testing things out with a bench power supply, but it seems to be working. Despite my love of building my own stuff, I’d probably just pony up for a commercial product. His site is hosted on his DSL, so I’ve put up a mirror
here
. (with some tweaks to the thumbnails to make them load faster.)

I’ve spent about 18 of the last 24 hours working on milling a PC board for my upcoming how-to. So far I’ve murdered several copper clad boards, built a hold down table, redesigned the board in eagle at least five times and snapped off a $15 half round engraving bit.
If you’re wondering, my new board milling table is a piece of MDF that I laser etched a .25″ grid onto, then added some aluminum strips to act as hold-downs. On the side of the strip opposite the board, I put thin slices of PC board to level out the hold downs. As usual, I’m building the board in
eagle
. To turn the board into something the mill can handle, I’m using
pcb-gcode
, a nice little g-code generation tool for eagle. I may switch methods later, but if I can get the settings tweaked, it’ll make my design to board milling process very fast.
[Scott] sent in the beginning of his attempt to build a frequency detector. He’s
started out
with just simple LCD matrix. Nothing intensely interesting just yet, but I like it when people send in stuff they’re working on.
If you haven’t checked out the
Arduino
yet, do it. It’s the easiest micro controller dev platform I’ve seen. If you’ve got one, now you can hook up a
Wii-Nunchuck to it
. If you like smaller and cheaper, check out [ladyada]’s
boarduino
.
[eliot] wanted me to mention
this
video on hacking drive through speakers. It’s a bit cheesy – and all I could think of was
Thunder Run
– where the geek character swapped the crystals in the CB radios. (Warning, The FCC might have some expensive words for you if you get caught.) Update:
this
is what you get if you don’t watch the entire video and catch the joke about taking apart toasters.
Tomorrow I should be picking out some winners for my laser etched laptop (or whatever) offer. You can still win some free etching time! Just send in a
tip
! The winners are selected from the ones that get published on Hack-A-Day.

Also, why are the leads of the crystal in the toaster so huge? Would the filters in the CB work at all in that frequency range?There seem to be a lot of problems with this, but I’m really hoping it’s true.",

[Bryan] sent in
this
old but excellent guitar cable hack. [J. Donald Tillman] managed to fit a fet based pre-amp inside the 1/4″ connector of a guitar cable. It’s phantom powered – so it’ll leach power from the sound board/mixer. I’m just impressed that he fit the thing inside there.
On a side note,
This
is the kind of crap that gives hackers a bad name. I hope the jerks behind it end up as Soylent Green.

with the
Novint Falcon
haptic controller. He’s put together a ‘brain dump’ of everything he know about the device – and some notes on his efforts to put together his own software library for the thing. I’m definitely interested in the parallel robotics platform that it appears to be based on.

[Daniel] sent in
his
Nixie tube VU meter. It uses 14 Russian IN-13 Nixie bar-graph tubes. He built a custom circuit to amplify, filter, smooth and feed a voltage divider to assign signal levels to segments and finally some high voltage transistors to drive the tubes. The circuit looks pretty big, but it’s repeated for each tube – so he worked hard to keep the cost down as much as possible. Now this just needs to live on the front of a massive tube amplifier.

(More on gas tubes here –http://ozvalveamps.elands.com/vrtubes.htm)Having noticed a lot of graphic equalisers going cheap in second-hand stores I have been thinking of doing something similar employing the ready-built filters (gyrators) and metalwork, replacing the slider controls with LED strip displays.I intend to use a LM3915 log LED bargraph driver chip for each band, and these would very considerably simplify this particular circuit after the filters. They can also be cascaded to provide 20 steps if desired.These can be run in bar, dot, or (with a bit more complexity) bar-with-peak-dot modes like the iPod display.As a soundie I consider graphic eq’s to be an instrument of the devil, and since they are generally too light to serve as a doorstop or boat anchor, conversion to a graphic analyser is their most fitting destiny. :)",

Adding
PoE
(Power over Ethernet) just
wasn’t good enough
for [steve]. Not only does he have power running over his Cat-5, he shared the ground wire and used the remaining pair to add a serial console to his rooftop mounted wireless router. Nice.

"content": "The motivation for getting the device as close to the antenna as possible is signal loss in the cable. At 2.4 GHz coax cable is *very* lossy. For example, good RG-58 cable has a loss of 18.3 dB per 100 feet at those frequencies. In only a 16 foot run you’ll lose 3 dB, which is half your signal. It’s even worse for thinner types of coax, like RG-174.This isn’t a problem you can solve with more shielding; it has to do with the foam dielectric between the inner core and the outer shield, which becomes lossier with higher frequencies. The only way around this, besides using very short cable runs, is to use waveguides, which are very unwieldy — hooking them up is more like plumbing than wiring.When constructing an outdoor enclosure you need to think about condensation as well as water intrusion from rain. In commercial enclosures the usual practice is to either include a small “breather” hole on the underside and include a heat source to drive out moisture, or place a packet of silica gel inside the enclosure before sealing it to dry the atmosphere inside.",

At 100 feet, the cable should have a resistance of 5.16 ohms per conductor, so 10.32 ohms per V+/Gnd and TX/RX. If, on power, the router is pulling 1amp, you are dropping 10v, so only 2v would get to the router. I’m assuming its .5a or .25a, so dropping 5.16 or 2.58v, so you get 7v or 9.5v at the router. For the serial port, what power/logic levels is it running at? 5v? I doubt it’s 12v. How much current is the router sinking for data?Grab another 100 foot cable, add a 14ohm resistor to one end, and then 12v to the other end. It should pull .5 amps and measure 7 volts at the resistor. Adjust accordingly.",

It’s affordable for less than a dollar a foot. Connectors are $20 a piece though. This runs to a high gain vertical, and I can reach out even further using my commercial equipment I have on the tower.The best thing to do though is get yourself an amateur radio license, then you can get into the good equipment that you can put some power behind.(The technician license should be a no brainer for anyone reading this site.)",

If you’re at all interested in using PoE, go google for 802.3af where a really quite standard has been laid out. Then, go purchase some magnetic modular RJ45 jacks for a very small cost and swap them into whatever device you need to PoE enable. The 802.3af standard has numerous failsafes designed into it, when you look at them it really is a no brainer. The various jacks have centre-tapped transformers with series and shunt chokes to filter common mode interference. It’s perhaps a few bucks of gear and a lot less work.I would also recommend injecting at 48V and using something like DC-DC convertors or even just a potential divide to get the voltage levels you require at the other end. For more than a few meters of cat5 it’s just common sense to do so. When running 48V you can get the full potential of 15W out of your 4 ‘spare ‘lines (there are also draft standards for about 56W but you’re looking at phantom power techniques here)Good luck.",

[Tuckie] sent in his
wireless fireworks controller
. The electronic parts are off the shelf – a 12 channel relay board and remote provide the guts. He used a rock tumbler to mill the black powder needed to make the detonators. A combination of the fine ground black powder, nichrome wire and ping pong balls makes up the business end of each detonator. When a channel is selected with the remote, the relay is activated, current is sent to the detonator which is taped to the firework fuse.

Doesn’t sound like a good idea to me, you already have to go through a lot of trouble to make a wired solution “safe”…there is really no reason to take the risk of going wireless if you don’t have a professional multi-thousand-effects firework distributed over a big place.Combined with the homemade e-matches this can go very-very-very wrong. Looks nice though ;-)ps: Milling blackpowder??????WTF?????DON’T DO THAT!!!! I hope the article means the components…If you really want to make these matches just use some normal crackers, they are fairly safe to open and provide enough to make lots and lots of these, you don’t need much blackpowder anyway…selfmade most of the time isn’t worth the effort (and the danger), you have to build a ball mill, get the ingredients and spend hours to get it right. Wasted time/money if all you need are some gramms………..Oh, and safety Sam says:* Wear goggles so you can enjoy your eyes if something lights accidently and burning chunks of blackpowder go airborne.* When messing with dissolver do it outside or with the windows wide open. The evaporation aren’t healthy and might be flamable if the concentration is high enough.* Beware the carpet, static e is your enemy.* Blackpowder might ignite due to friction, be aware of that. If you ever get to the idea you have to compress bp DON’T rub it around.* Last but definetly not least: Check the legal situation in your country before messing with fireworks…@my place (germany) creating this e-fuses would be illegal. Hell, even opening the cracker is a violation of explosives law. The certified (legal) e-fuses/fuses are quite expensive but at least they are guaranteed to stand a certain current for a certain time so they won’t light due to static electricity, induction or something else Murphy might think about. When it comes down to paying some bucks extra or (maybe) hurting somebody while messing with selfmade stuff………….anyway, just have respect when handling with explosives and highly flamable stuff. Thousand times nothing happens and then somebody gets hurt because you thought you had to save some $.Anyway. If you are adequately carefull when messing with them fireworks are great fun ;-)",

Our own [Eliot] dug this one up from the grave. While
the recipe
has been online for a while, do you know many 10 year olds who made their own
Aerogel
, that wonderful insulator that’s essentially gelled air? [William]
made some
(
cache
) for his science project in 2002. He started with Silbond H5, a combination of ethyl alcohol and ethyl polysilicate. You can get the MSDS after a painless email registration on the
Silbond website
. After the gel is formed you have to soak it in an alcohol bath to make sure all water has been removed from the structure. Then the gel is placed in a drying chamber. Liquid CO2 is forced into the chamber to displace all the alcohol in the chamber and the structure. Once the the alcohol is gone the supercritical drying phase begins. The temperature is raised to 90degF and the pressure is regulated to 1050psi. At this point the liquid CO2 in the gel structure takes on gas properties (looses surface tension) and leaves the silica structure. All that remains in the chamber is your new Aerogel which is 99% empty space and 1000 times less dense than glass.
Of course, if you’re lazy, you can buy some

"content": "The year before, William spent hundreds of hours reading around 100 web sites about aerogel, emailing universities and corporations about the stuff, receiving a handful of samples, including a 4″ disk, touring the plazas in Bakersfield to interview citizens, and preparing his report. For this project, I, his “big brother” conceived the idea of making aerogel at home. I consulted with him about how to design the mechanicals. I had to request the Silbond, because the company would not send it to a minor. I drove him around to the metal surplus yards where they advised him on schedule 80 pipe, fittings, valves, and gauges. Many of these were donated. He acquired the ammonium hydroxide and pure ethyl alcohol from Cal State Bakersfield, though I had to sign for it.He made the raw gels and the alcohol baths. I tightened the larger fittings because even with a 30″ pipe wrench pair he was not strong enough to seal them. He did the work of temperature control with both ice in the first stage and hot water in the second. Ice had to be applied a few times each hour, and hot water every few minutes to keep the temperatures first below then later above the required levels. William did all the work at every stage. I, however, also had to loosen the large pipe fittings after the process was completed. Then William had fun spraying the remaining CO2 all over the yard, freezing weeds, and having fun.I am not a college graduate, William’s guardian is now 85 years old and lives in a hodgepodge of an old house.In conclusion, while we collaborated on the design of the project, and I did the things not allowed for a minor, or that were physically beyond his strength, William did this project. He had technical assistance from the University of Virginia, Aspen Aerogels, U Cal Berkeley, and NASA employees.",

It is very brittle, if dropped from even a small height it will shatter. Would make a terrible bike frame.Aerogel is no more toxic than glass, you should avoid inhaling glass dust and eating it although it probably wouldn’t kill you.Normal aerogel is hyrophillic and gets destroyed when contacted with water, however it can be made hydrophobic with post-processing or with a different precursor chemicalAspen Aerogels add in some plastic or something to make it bendy, and have some cool names for it like Pyrogel!Aerogel is not a closed structure as it has open pores through which gas can diffuse. I think it takes ~1ms for gas to diffuse through 1mm of aerogel.I don’t think the child was achieving anything that NASA could not, as this was the first way in which aerogels were created.

Semi-duplicate Post Extra

"Misc Hacks"
] |
[] |
[bgugi] was the first to notice that yesterday’s post had been seen before, tucked away in an extra last year. (I do check for these things, but it slipped through.) I honor of my little lapse, here’s a fully loaded extra.
[Matt] scored some
interesting hardware
next to one of the local dumpsters. He also just put up part one of
his coil gun
based on ten $1 disposable cameras.
[Darren] sent in
this
USB webcam that was mounted in a Canon FX SLR body. Now the cam can be fitted with old (inexpensive) lenses for better performance.
[Brandon]
really
likes his XBox live – enough to set up access via Sprint EVDO and install everything in his Mini Cooper with a set of VR glasses and controller in the glovebox for instant access.
These were all over the place this week, but I wanted to put them out there. [Pablos]
showed BoingBoing
how completely lame RFID enabled credit cards are. And it’s way to much fun to watch this dog play with his own
robotic ball tosser
.
[Jason] sent in his
altoid tin guitar
– he slapped a piezo inside the tin to get signal out of it.
[David] sent in his older, but still awesome
Segbot
. It’s a balance bot that’s controlled via wireless modem with camera feedback.
Last and definitely not least, [Basil] sent in his
Midistrip
guitar mod. He added a capacitive touch strip to the body of a guitar and uses it to create midi output. Check out the demo vids
here
,
here
and
here

[Nuri] sent in
his
rather interesting gaming feedback device. The TrakonyaMutatorUSB is a USB based armband that’s designed to shock you when you get shot or killed in your game. I can’t comment on the safety of this thing, but I guess it could be a good gift for your enemy gamer.
Update: Just to clarify a bit, This is built by [Nuri]. He offers them for sale (via paypal I see), but it is his work. It would be nice to see the design, but I can see some reasons why he might not want to release it to the public.

[Shadow] sent in
this
handy idea. For many, it’s sort of a captain obvious hack, but I’m hoping that this might keep a few of these things out of the trash. He needed to send video around the house from a media PC, and happened to have an old XBox RF modulator sitting around. He popped it apart and located the audio and composite video inputs. To get the signal to the rest of the house, he plans on installing a distribution amplifier that’ll amplify and split the signal to each TV set.

The device works perfectly with a normal composite input, although it only creates sound for the right speaker, so the left speaker is always dead.. I’m planning to get it conencted to the antenna connector under my desk. The cool thing about it is, that our neighbours and we use the same antenna, so if I feed in a signal my friend in the house next door should eb able to see the stream as well. I also found an amplifier with two outputs. It’s so strong that if you connect a normal telescope antenna to it and one to your TV-set, that is about a meter away, you get a perfect image on the tv. As we don’t have cable it shouldn’t be a problem to feed the video signal to the antenna cables in our house. The only problem might be that the antenna on the roof *could* send the signal to other houses, too. But… who cares :D",

We made a point to stop by [garrett]’s booth at Maker Faire to to see what he had been working on. You may remember him from his
random caps locker
shenanigans. He’s just recently released the
ShiftBright RGB LED module
which makes it easy to implement a string of individually addressable LEDs. The module is based on the Allegro A6281 3-Channel Constant Current LED Driver. The driver chip is capable of displaying a billion colors using an RGB LED. The 3x3mm package is mounted to the backside of the board while a bright common-anode RGB is mounted to the front. The modules are designed to be daisy chained together and are individually addressed using a serial interface. You can find
Arduino example code
on the site and more info on
how the item was developed
. Read on for close up images.

[Romado12187] just posted a walkthrough of his
mechanical dry erase board
project on Instructables. It was on display in the Microsoft booth last weekend at Maker Faire. Unlike [sprite_tm]’s version
we covered earlier
, this one is built more like a traditional pin plotter. The construction was done entirely in [Romado12187]’s dorm room and uses plywood and PVC pipes for the majority of the frame. The mechanical components were purchased from
SDP/SI
and the controller hardware are
Phidgets
. He included a joystick, but it also has a C# command line program for control. [Romado12187]’s write up also has a lot of improvements to help make your first attempt better than his; buying a premounted board and being very exact in calculating motor power are recommended. Catch a video of the plotter in action after the jump.

is better than the average lead acid trunk fest. The pack was built from three prius NiMH packs picked up from salvage yards. These batteries can’t simply be bolted together, but with some research and effort you can save some nickel from the junk yards and cut your fuel bill.

The only way a extra battery can give the hybrid system more power is through the over charge protocol, which is what all plug in conversion kit uses. By pushing voltage above 340V computer will read over charge and force the hybrid system to quickly get rid of the extra voltage by using more assist before the hybrid battery burns up due to over charge. Down side to this setup is unable to regen the extra capacity of the add on battery and possible over charge and damage of the original battery. After a month of testing the improvements to the mpg minimum at best. Not worth the money and time used to build the circuit boards and connection to make this setup work.But my other project Honda first gen Hybrid system found in the 00-06 Insight and civic hybrid is hackable to accept a bigger battery and give you 100% control over the assist and regen function of the hybrid system. Was able to obtain 150 mpg avg over 38 miles (which is the max calculable mpg on the Honda, so might have been over 150) with this setup in a 00 Insight.",

Builder [Justin Gray] brought a pair of electric motorcycles to Maker Faire last weekend. Pictured above is the
R84
, which has 28 LiFePo cells and an 84v AC induction drive providing 54HP. All of that is stuffed in a 2000 Yamaha R1 frame. You can buy it now for $14,000.
The second bike is dubbed the
R144
. It’s a144v DC system with 48cell lithium power supply driving a 60kw series motor.
[Justin]’s other passion is building fire robots like
Libby
pictured below.

UPDATE:
Skype has
withdrawn their appeal
and accepted the original judgment.
Tomorrow the High District Court of Munich will hear
Skype argue against the validity of the GPL
. Last June, the court
issued an injunction against Skype
for selling the
SMC WSKP 100
, a Linux-based WiFi VoIP phone. After the initial GPL violation, a flier with the URL for the source was added to the package. The GPL wasn’t provided and the court found this insufficient for fulfilling the
requirements of the GPL
.
Skype
is appealing and claims that
the GPL as a whole violates anti-trust regulation
. The case against Skype was brought by
OpenMoko
‘s original system architect,
Harald Welte
, as part of his work for
gpl-violations.org
.

It’s not like there’s some “universal default license” that’s more restrictive than GPL that applies to all software if no (legal) license is specified.I like the idea of having a boilerplate standard “copyleft” license that you can just drop in if you want your code to be free. But I don’t like the idea that in order to sell a product that uses any of that code, you not only have to include the source of the GPL’d code you used (which is an unnecessary burden when your consumer is quite likely to have Internet access), but AFAIK you’re also pretty much required to GPL your own code, whether you want to or not.In short, I agree with #2: it’s “too viral”, and I think that quality is going to do more to hold Linux back than a thousand MS marketing campaigns.",

I think it extraordinarily unlikely to succeed, but I think I actually can see their argument, and I can’t swear it won’t.

What baf refers to as “viral” is the pejorative way to discuss how the GPL preserve user’s software freedom (the freedoms to run, inspect, share, and modify at any time). A more fair way to understand why and how these freedoms are defended in the GPL is to understand the concept of “copyleft” (seehttp://www.gnu.org/copyleft/).If anyone doesn’t care for the GPL they can write their own code and copyright law gives them the power to license it as they wish (the act of licensing is a power, not a freedom, because licensing means setting rules that affect others more profoundly than oneself). Free software hackers have no obligation to aid proprietors. It should be obvious that proprietors have operated on a similar philosophy, but what makes them worse is that their programs deny users the aforementioned freedoms and in so doing deny users independence and community of people who can share with each other.So having software freedom (which all free software licenses respect) is great, but defending software freedom (which only the strong copyleft licenses such as the GNU GPL do) is better.If we don’t talk about the value of freedom we’re much more likely to lose it. The values the GNU Project stands for should be understood as valuable in their own right, as good unto themselves.",

The code isn’t public domain code, you used it in a way that the GPL grants with certain responsibilities in mind, and you failed to meet those responsibilities.As contract law, it’s a pretty clear issue.",

If I want the source code I will have to download it seperately.Regarding rereleases to the community, I think this is only fair for smaller contributers. It protects open source projects from companies who intentionally take code from an open source project and “extend” it with their own proprietry extensions, effectively killing off the initial effords. Check out Microsofts embrace extend strategy.There are licenses which exclude the rerelease clausel (BSD, double licensed) but while it is certainly subjectiv from my point of view, I have the feeling that many of them are less frequented and often lack documentation compared to gpled projects.",

The
nitty gritty details
are a little bit hidden, but [Sylvain]’s work is awesome enough that I just don’t care. He’s been doing research on robot learning with some
tasty results
. After all, who doesn’t want a robot to make breakfast for em? He’s taken the time to publish some
source code
, so robot made breakfast isn’t that far out of reach. mmmm.

is a large scale kinetic art project. The electrically powered spheres move by shifting the batteries around the center axle. By tilting the central ring, th orb can steer as well. The SWARM members are currently radio controlled, but the plan is for them to eventually receive commands from a mother node. More information about the orbs’ design is available on the
project wiki
. A video of the wobbly buggers in motion is embedded after the break.

[Tim], builder of that sweet
NES pad controlled Silvia
espresso machine put up an
interesting idea
for
voltage
current
monitoring – at least, for AC circuits. In a nutshell, he created a mini transformer by wrapping some wire around the outside of one wire of an insulated AC power cord. Espresso machines use 120/220VAC actuated solenoids, so that’s why he’s so interested. I love the idea, since the detection circuit is just a piece of wire.

Underwater GPS (sorta)

"gps hacks"

Since water blocks the radio frequency used for GPS triangulation, GPS is considered pretty useless for SCUBA divers. Apparenlty some of them are
finding it useful
to waterproof off the shelf units for tracking the beginning and end of dives. (Dives in open water often involve currents that can really move you along.) To avoid any wiring, a floating case is used. When the diver wants to grab a waypoint, he/she lets the gps surface for a short while to acquire a fix. Then the diver can pull it back down and mark the waypoint or record the coordinates.

Two, no way am I dealing with 200′ of line at 100′ with a current. The 15′ on my Mares is enough to deal with. Three, God invented compasses for open water dives.

Recently I’ve been towing a dive flag that has the ability to deploy and recover the gps unit…it’s just like pulling a flag…no more complex. One advantage of the methods I use is that the diver works with a small diameter line, not a data cable / floating antenna. My goal is to keep the equipment from dominating the dive. Also…many divers will not “get” the need for gps because they do not dive frequently enough to make it worthwhile. This is intended for researchers, public safety divers, law enforcement teams, and the more avid divers that live near frequently visited sites. Aside from marking points, a constant awareness of the anchor position is maintained.",

So you have a problem you are in a forgein country and like it has happened so times the don’t do an accurate dive count and you and your buddy surface, no boat. Well rescue is going to monitor all radio channels and go to the last place the boat was. So know you can send out emergency radio calls stay in the area the boat was and comminucate with rescue boats and aircraft. The radio options allow you to communicate and track others also presetup, that helps solve some of the issues of missing divers if they have made it to the surface or close to the surface. I would imagine soon they would put in a ping, user activated to help again rescue find you. Yeah bad idea, but I will spend 1,000.00 on something to save my life.",

"Laser Hacks"
] |
[] |
After months of waiting, emailing and waiting some more, I took the afternoon off to stay home and wait for this special delivery. (I had to wait an extra day due to a shipping issue!) I received three huge boxes in my workshop. Not only did I receive this (not so mini) Epilog mini 24, I put together a stand and unpacked a monster air filter.
Read on for the obligatory Hack-A-Day logo and my first impressions of this sweet piece of kit.
First off I had to unpack and put things together. Assembling the stand was pretty easy – but my electric screwdriver made everything much easier. The laser has an I/O board with a test socket, USB interface and a network interface. Once I connected it to my network, I decided to be lazy and look up the dhcp address on my server – and failed. Surprisingly, the system doesn’t support DHCP. This isn’t a deal killer, but it meant that I had to wade through the setup instructions to manually set the interface. (Epilog just leaves it setup for the usual private lan: 192.168.x.x.)
I took a quick look inside the box – and was surprised by just how small the servo motors are. They’re about the same size as a 1/10 scale model car, plus encoder. The X/Y assembly only moves a small aiming mirror, air gun and auto focus tool, so it doesn’t need to be very large.
Once I got a feel for using the print driver, I grabbed some scrap pine and got to work. I loaded up some Hack-A-Day logo vector art, filled in the areas with some color and sent the job off to the machine. The laser doesn’t do anything until you’ve pushed the go button on the device, so you can send a few jobs to it at once if you like. (The buffer holds 64, I believe.)
On the whole, I’m pretty impressed with the machine. It’s built like a tank, uses servo motors to actuate the X/Y axis, and allows you to use a Mac or windows PC to drive it. If you’re doing multiple runs, you simply select the job, line things up and hit go.
I haven’t picked a winner for
the Hackit
just yet, so keep on sending up ideas if you’ve got em. We’ll be offering more chances at getting your gear etched as time goes by, so stay tuned!

I just spent a little time dropping in some

become a non-impact punch down tool

Hackit: Laser Cutters – With A Prize!

"HackIt"

[] |
I’m going to have a special guest in my workshop for a while: an
Epilog Mini 24
45 watt laser cutter. This is entirely thanks to
Epilog Laser
down in Golden Colorado. Here’s today’s hackit: If you had access to your own 45 watt laser cutter – with a 12″ x 24″ work surface, what would you make with it?
Oh, and there’s a prize on this one. Whoever comes up with the best idea will get a free laptop engraving session. (You can always just ship me the display cover.) You can have your own art put on, or we can always tattoo your machine with the Hack-A-Day logo.
(Pictured is Ladyada’s laser cutter. Mine’s coming tomorrow!)

If you thought there wasn’t anything else to shove on the end of your iPod, [Alex] is here to set you straight. He used the DC power that’s available on the iPod’s dock to drive a cheap laser pointer. It’s pretty easy to do – just get a dock connector (
sparkfun
has em) and add a laser pointer module. If you’d rather access everything else, check out the
super dock
I put together a while back. Hit the
read link
if you’d rather see the picture in color.

this
interesting
laptop
modding project. He started with a Spectrum ZX and a Toshiba Libretto 110. The libretto kept its brains, but the lower case and keyboard was replaced with the ZX hardware. Since both machines use matrix style keyboards (but different matrix layouts) he was able to create a passive adapter circuit to match things up.

[Andrew] sent in
his
low voltage coil gun. He used some control hardware that most hardware hackers probably don’t have on their shelf, bit it’s still a good proof of concept. Each coil is driven by a dedicated relay, and a PC power supply feeds the system juice, while a programmable logic controller does the work. Since it’s just a matter of triggering the coils in order, the PLC could be easily replaced by a micro controller.

Since the coils are handwound anyway making room for a LED/photodetector pair would have been trivial. In fact, with that approach you could do with no controller at all.It’s the current pulse, not heating, that damages relays, and the high voltage kickback from inductive loads. However, if he’s using industrial relays rated for 10A they will probably last quite awhile since he isn’t cycling the thing every half second. The clampdown time might affect his timing, though; I think I’d have tried a simple bipolar transistor like a 2N3055 with a diode reversed across it to absorb the inductive kickback voltage. It’s not like you need an H-bridge or PWM to do this.",

As far as photo detectors go they probably wouldn’t be the right approach here as they would require an even faster response time and, using scr’s triggered by the photo diodes only works with capacitors since you would need additional control circuitry to terminate the pulse.This particular logic controller is also relay based but they were rated at 2A so I used larger ones to protect the expensive controller. This addition did cause the clamp down to become a limiting factor (I doubt I would be able to get it going any faster)Its also not ment to be a finished project just something I came up with on a rainy weekend so I used what I has and what I could get locally.~Andrew",

It seemed that even tiny differences in the starting position, power supply, friction etc. got amplified through the three coils to the extent that sometimes by the thrid coil the timing was so far out it would backfire yet other times it would work great.My conclusion was you really need some sensors to combine with the timing. One after each coil would probably suffice and the rest of the timing can be done in a pic. My ideas for sensors were light gates (ir led and detector pairs) or metal brushes that connect with a metal projectile. Timing accuracy is probably only important to ~500 µS, so pretty much any kind of sensor would work. I ran out of time so all those improvements never got done.One thing that seemed to limit it was the de-energisation time of the coils – effectively we couldn’t switch them fast enough due to arcing in the relays.Watch out having sensors near the coils, because the magnetic fields from the coils could induce currents in the sensor wires and fry your sensor or controller.",

"content": "This comment is directed at anyone looking for super-fast switching (not just Andrew) or looking to spend more than a weekend on a coil gun. Great hack, Andrew!Using relays for switching can introduce large mechanical delays, so using a solid state approach is much faster if you can get it implemented correctly. Using BJTs, like the 2n3055 that localroger suggested, could probably work but if significant amps are required then it will not be able to source all of that current. Plus, BJTs are current-controlled current sources, and when used as a switch, their amplification is very small (approx 40 perhaps), compared to > 1000 when used as an amplifier.The best option IMHO is to use a low-voltage MOSFET. The diode for suppressing inductive voltage spikes is built into the FET, plus since the FET can only block say 35-ish volts, you can get some SUPER FAST switching, like in very small microseconds. These are the devices used in high-frequency switching power supplies, like the CPU power supplies on the motherboard that switch in the 100’s of kHz.Also it’s important to know that during the inductive voltage “kick,” current is still free-wheeling through the diode and coil, so the coil is not yet turned off. Maybe that was said above but I missed it. You’ll probably want to shut the coil off before the projectile hits the middle of the coil or you may end up slowing down the projectile. That is, of course, assuming the switches/FETs/etc can be controlled accurately enough to do so.These are by no means the only way of doing this, just my overeducated thoughts on the subject.Again, Andrew, this is a really cool hack and I echo strider_mt2k’s thoughts on your work!",

Want to get your laptop custom etched… for free? During the next couple of months, I’ll be giving away some free etching sessions. How do you get one? Just submit a fresh new hack via the
tips line
. If it makes the cut and gets published, you’ve got a chance to get your laptop or gadget etched in this 45 watt epilog laser cutter. Here are a few guidelines to help you win:
Make sure it’s fresh. Use google for 10 seconds to make sure it hasn’t been published on a major blog already.
Make sure it’s got a picture – everybody likes a good visual aid.

Plumb In Your Espresso Machine (cheap)

A while back, I wrote up
a how-to
on some mods I made to my ECM Giotto espresso machine. After giving it some break-in time, I finally wrote up my cheap plumbed in espresso trick. Plumbing kits use a $50 solenoid that requires special plumbing.
My version
uses a $12 fridge solenoid, easily adds on to my previous mods, and only requires some tubing size adaptation.

gutted
some li-ion laptop batteries to replace his roomba’s battery pack. He had to pick up a li-ion charger and add a protection circuit to deal with the li-ion cells, but ended up with a new lighter pack for his roomba. If you head this way, the protection circuit is a vital component to prevent fires/explisions/etc. Looks like a great resource for robot power or even R/C projects.

It now runs 2hrs+ :-) As long as you keep the battery safety/balancing circuit, you’re safe, it checks that no over/under voltage situations happens. My roomba charges with 1,3 Amps max, which is below that of the HP laptop would do, so the cells is cool to the touch, nothing to worry wbout. The voltages fits nice too, a fully charged NiMH pack is 12×1,4 volts = 16.8 volts, and the LiIon pack is 4×4.2 volts = 16.8 volts, so it’s a perfect match for the charger circuit!. My roomba even senses when the batteries are getting low, homing for the charging cradle again without the power dying on the way – problems other LiIon-adpoters have, since theyre safety electronics in the cells work differently. Just a single word of advice if you’re going this way – do NO at any single moment, disconnect the cells from the controller on the battery pack when re-orienting them – the smart battery controller will blow a chemical fuse on the controller, making the battery useless, unless replaced (done that, got the t-shirt etc.) Happy hacking folks.",

I have two NiMH 4000 series packs that are several years old but were barely used, and one brand new one that was never used, and all won’t charge. Two different Roomba chargers give me the flashing red light on the robot, which after a time goes green, but all three packs make the robot play the same dead battery tune a second or so after turning it on. Very disappointing, and very bad battery economy IMO, so for that reason I’m considering going liIon. I’m confused by your word of advice, however. What do you mean by “do not disconnect the cells from the controller on the battery pack when reorienting them”? I assume you’re referring to the charge controller on the LiIon pack, but what does “reorienting them” mean? If a typical 4S1P pack with a charge controller is used, would not the controller come pre-attached to the cells? If not, what cell/controller combo would you recommend I purchase?

I chose a 3300mahr 35C 4s1p Lipo pack and the DROK® 14.4V/14.8V/16.8V 4-series Lithium Battery Pack Overcharge/Over-discharge/Overcurrent/Short-circuit Protection Circuit Board for battery management. Both are working perfectly. The 3300 pack barely fits in the case lengthwise if you grind off one screw mount with a Dremel and place the DROK board alongside the battery where it won’t touch either the battery or the case wall. I also removed the over-temp sensor from the old pack and slid it inside the sleeve of the Lipo pack just to be safe. If you use the DROK board be sure to place a jumper or zero ohm resistor on the Automatic Activation Function pads and be careful with the solder as the SMT pads are damn near microscopic (see location in the Amazon ad). These boards do not come with this jumper preinstalled for some reason. My ten year old but barely used Roomba 4130 (barely used due to a failed wheel sensor and constantly failing NiMH packs) is now working quite happily on its new Lipo pack (and repairs to both wheel sensors). She’s lighter and peppier than before and finishes a whole room without draining the battery. She also parks herself normally and the flashing red light even goes green when the charge is finished. These tasks were always difficult before and Roomba refused to repair it after the warranty expired. All-in-all, I couldn’t have hoped for a better fix.PS: You can make your own triangle screw driver by taking a six-point star-bit from one of those cheap Chinese 30-piece tool kits and grinding off three points with a Dremel grinding wheel.",

M3 Headphone Amp
|
Will O'Brien

"Laser Hacks"

[] |
If you’re serious about your headphone amps, you probably already know about the
M3 headphone amplifier
. Instead of going for the extra tiny, they’re going the ‘screw the size, it’s all about the sound’ route. Thsi thing needs a 24v .5amp power supply. Boards are available, and the discussion has gotten so long on headwize that they exceeded the
maximum thread length
.
I got busy with the laser last night and came up with
something new
: a custom etched track pad. It still works, with a bit of added texture where I introduced it to the warm glow of the laser. Hit the link for pics and a walk through.

Desktop Soldering Press

[kruser495] put up
this
interesting instructable on making a desktop soldering press out of a sewing machine pedal. It uses a big chunk of carbon to create a diy high power cold-heat style soldering surface. It doesn’t work until the top is pressed down to complete the circuit. Looks like it’s only useful for wire joins, but still pretty interesting.

This is an older set of hacks, but I’m surprised we haven’t covered them before. The playstation controller is an interesting alternative to normal robotic controls.
This
PS1 controller to serial interface is based on a Motorola HC68 series micro-controller. This even
simpler version
only needs some diodes to interface with a parallel port. Probably more interesting is
this
how-to on using a wireless PS2 controller with a basic stamp II.

FIRST Robotics Regional – KC – 2008
|
Will O'Brien

"News"

When you’re issued safety glasses at the door, you know it’s going to be interesting. As promised, I’m checking out the FIRST robotics regional in Kansas City today. The competition is pretty fierce – not quite flame throwing battle bot action, but the kids have put together some pretty serious robots.
Read on for more pics from the competition.
Most of the bots share the same basic design features – mainly because each team is issued a kit of stock parts to start out with. I spent most of my time visiting the teams in the pits – checking out their designs and asking them what the favorite part of their bot was.
[Team 2385] – Wright Christian Academy was one of my first visits. They built their own high torque steering system (and winch drive) using some power door motors from a van. They look about the same as older windshield wiper motors. They added a linear potentiometer to the linkage to create their own super servo. I’ll probably re-create this on one of my future projects.
[Team 1996] came up with this interesting gripper for their bot. The arms lever up and down, but the gripper has a static chain drive to keep it level the entire time.
[Team 1108] built one of the most entertaining bots to watch compete. The arm is a catapult, but it’s tipped with a trash can lid with a hand sewn rubber seal. Just underneath is a fan assembly from a shop vac – but the AC electric motor was replaced with a DC unit. It did a fantastic job of picking up the giant ball – and launching it with the arm.
A while later I caught them tuning the catapult. It just launched the ball, just about nailing the guy standing directly in the path.
[Team 1775] put together this sweet control board for their bot. The controls are standard fare, but most of the teams settle for mounting them on a piece of wood.
[Team 1981] had to scrap their pneumatic arm at the last minute, so they settled for making their bot short and solid. Last time I checked, they managed to score pretty decently by just pushing the ball with their bot and making around the track as fast as they could.
For the autonomous round, one team needed a bit more range for their IR remote. Commands 1-3 tell the bot which slot is needed for the target ball. Sending a 4 kills everything. (off, not all humans.)
[Team 2164] built this aluminum hand shaped gripper. It looks fantastic, but I haven’t seen it in action yet, but it looks awesome.
I liked this little construction trick. The frame is built by pop-riveting aluminum plates to join the structure. I’m not sure how durable it will be, but it looks like a nice way to speed up construction.
I didn’t get a chance to talk to every team I wanted to – they’ve all been working pretty hard. When they’re trying to solve a problem or get the bot ready to roll, you can’t miss the activity. If you get a chance to check out a FIRST competition, take advantage of it.

I was doing some project window shopping today, and FPGA’s came up on my list. [John Kent] put together a pretty impressive
documentation set
. He’s written up some of his own projects, some how-to’s and linked plenty of good information for the budding FPGA programmer.

"content": "I agree that FPGA’s rock and I am happy they are getting a bit more attention due to the awesome power they have.However – I find that this FPGA page really talks more about implementing a CPU within an FPGA and writing C or ASM for that CPU. While this may be one thing you can do, it by no means actually exploits the inherent power within the FPGA. You are still writing sequential code to be executed within the FPGA instead of just buying the cheaper hardened silicon.VHDL has inherent parallelism based on concurrent processes, but the biggest turn off is the strict typing of the language (If VHDL is too strict, you can try Verilog, but when it comes to building hardware, you may prefer to be as strict as possible). Once you’ve passed this obstacle and have a good understanding that what you implement goes into registers and look-up tables, it’s all very easy going.I recommend searching for the “VHDL Cookbook” for a great primer on VHDL.Lastly, it should be realized that there are two flavors of VHDL that you can target – VHDL for Synthesis (programming for FPGA’s and other programmable logic devices), and VHDL for Simulation (testing cases, assert statements, floating-point calculations, etc). Some things which are nice for simulation (time delays, large for loops that can’t be parallelized, etc) are NOT synthesizable constructs.@giskard: VHDL has the same programming structure as Ada. If anyone has ever programmed in Ada, then writing VHDL is a natural extension.",

Bad-ass Modular Snake Robot
|
Will O'Brien

[
"Robots Hacks"
] |
[] |
[Andrew] sent in this sweet snake robot video. The
snake bots
are all about 36 inches long and built from lots of hitech servos and 6061 aluminum. The guys/gals at Carnegie Mellon have built quite a few of these, and I’d say that their work is paying off. They haven’t published much in the way of details, but it appears that the snakes are being computer controlled for faster behavioral development than an on-board mictrocontroller would allow. When I saw the snake motion I was reminded of the winner of the latest
Tresser robotics contest
–
Phoenix
. It’s a spider like bot based on servos, but with some very impressive motion programming that was designed with an excel spreadsheet.

Just a quick heads-up. I’ll be checking out the
FIRST robotics competition
in Kansas City this friday. It’s a robotics comp between teams of high school students – and the prizes include quite a few scholarships. I know we’ve got some readers who are in the competition. If you see a guy with a Hack-A-Day sweatshirt/T-shirt on, say hi and I might hook you up with some stickers. My day job will be providing
real-time video streaming
of the event, so feel free to check that out.

Here’s a good rule of thumb: “Don’t update your firmware five minutes before you’re going to fly an autonomous robot ten feet away from a former Vice President of the United States.”
That was one of
the afterthoughts
of [Chris Anderson] after presenting his Arduino controlled blimp at TED. (I might have to squeeze TED into my con schedule next year.) The project itself is somewhat documented here, with some hi-res photos, parts list, and some firmware. Apparently the blimp was overcome by the A/C in the auditorium, but I still dig it.

Given the position of the arduino on the microcontroller food-chain, isn’t that like saying everything is awesome-er in Java?I was so happy to read in the comments of one post that my fellow geeks felt the same way. Yes, Arduino is great if you absolutely can’t be bothered to spend a day learning to program a real micro, but doesn’t that nullify any past or future-potential geek credentials??This is in no way a rant against this project, or hackaday for posting it.

built
his own micro mill out of Lego NXT parts. The construction details are a bit light, but it looks like a great way to try things out without all the actual machine work.

CNC Mini-lathe
|
Will O'Brien
|
[

"Misc Hacks"

[] |
Given my obsession of CNC projects, I’m surprised that we haven’t mentioned
this
project before. [Dave] put together an excellent site about his CNC converted mini-lathe. (The same on that
I’ve got
) He built a pretty simple stepper controller to drive it. Since the lathe only needed two axis motors, he drove the steppers with some mosfets that he triggered from a parallel port. The site has been around for a while, but I thought you guys would enjoy a classic hack like this one.
