High Speed Photography

[Shakir] sent us this fairly easy way to do
high speed photography
. The idea is to use a microphone to detect a sharp sound on a surface and trigger the flash. The camera is set up with a long exposure to capture the action. Assuming your room is dark enough, you shouldn’t get much ghosting in your exposure. The circuit is a two stage amplifier that engages the flash using a
silicon controlled rectifier
. Be sure to check out the photos, some are pretty stunning.

Even with modern DSLRs, the fastest shutter speed is often maybe 1/4,000th of a second — far too long if you’re trying to capture a bullet in motion.With electronic shutters, it’s probable possible to have incredibly fast shutter speeds, but then you need huge amounts of light — it’s still far easier to make a blinding flash of light than to make a continuously blinding light. :-)",

[Garrett] took 30 of his ShiftBrite modules and
mounted them to his front fence
for Christmas. The
ShiftBrite
is a serially addressable high output RGB LED. The individual modules are quite adept at applications like this where you’re stringing multiple lights together. They have identical buses on either side, specifically for daisychaining. The installation above looks great.

The New York Times has published their
8th annual Year in Ideas
. It’s a collection of interesting research and policy changes that have happened in the last year. They cover several projects that we’ve found noteworthy in the past. Pictured above is [Max Donelan]’s
power generating knee brace
. It generates power as you perform mundane daily activities. Another pick was the
Brickley Engine
. It has a unique piston layout to reduce friction for increased efficiency. We were particularly interested in the research that discovered drone pilots become exhausted
far quicker than pilots in real aircraft
. It’s doubtful that this problem of “sensory isolation” will go away and we wonder what other fields it might appear in. They even mention [Josh Klein]’s
crow vending machine
. You’ll find something to pique your interest in the Year of Ideas, even if it’s
DNA forensics for dog poop
.

Sony Vaio UX 64GB Solid State Upgrade

"storage"

This Sony Vaio UX50 came with a 30GB hard drive from the factory. This hacker wanted to do an upgrade and move to solid state, so he started hacking away. He ended up with a total of
64GB of solid state storage crammed into the computer
. The hard drive was replaced with a 4GB compact flash drive and the rest is spread through out the device. Apparently any crevice or crack in the Sony UX50 can have memory shoved into it. He managed to somehow get 60GB of storage in there through various USB extensions and adapters. Notice the sticker on the inside of the case. Is this the latest fad? Decorating the inside of the unit where only you know it exists?

(not sure how vista handles that, sorry.)My question is if the system itself is taxed in any way by having all those USB flash memory devices plugged in all the time?I’d like to see some benchmarks.I’m sure it works great, but I wouldn’t want the management hassles of all those drives either.I have a netbook that I’ve installed a 16gb USB flash drive inside of as well, but I hesitate to install a hub or additional devices because of concerns over system resources.Looks like it all came together pretty well though.

iPhone dev team
is at it again. They claim to have finally
hacked the iPhone 3G
. Originally codenamed “yellowsn0w”, it is targeted to be released on December 31st. This should free you from your locked in carrier as long as you have version 2.11.07 or earlier.

If you updated to 2.2 using pwnage tool, and you selected not to update the baseband (as the instructions with that release said), you’re good to go.",

[nothans] felt that there were enough people curious about his toaster’s status that he
built a system to update the world via twitter
. Using the
ioBridge
module and a switch on the toaster, the world can now know when [Hans] is making toast. We recently saw someone use the same unit to
feed their dog remotely
.

Who hasn’t fantasized about
riding on a hexapod robot
? With these detailed instructions, you very well could be living out your fantasy very soon. As you can see in the video, they opted for connected legs instead of 6 independent ones, so your dreams of riding the
dancing Lou Bega bot
may have to wait for another day.

[Eric] was charged with the task of
setting up the train to welcome people on the porch
. The train had been in the family for a long time, so he didn’t want to modify the train itself. Luckily, it has an IR port. He recorded the IR signal from the remote and used a home made pressure sensor to signal the train to start.

As much as we love crazy prototype style hacks, we really enjoy seeing things that get used after their creation. [Marcus] sent us the information about his
automatic yarn winder
. Noticing that his friends who knit had to go through the monotonous process of winding a ball of yarn each time they started the process, he sprung into action. After finding only a few commercial solutions, which were out of his price range, he decided to build his own. He found a hand cranked version and gutted it to add a motor. Now, they simply need to get it started and walk away. Great job [Marcus].

I’m 70 years old and have done my share of rolling balls on winders, because when the yarn comes out of the center it does not twist while knitting. Also you don’t have to stop and pull on the ball to unwind it or pull out of a store bought skein. Also it gives the yarn a chance to relax before you start your project and the tension on the yarn is more smoothly knitted.I’m a double amputee and can’t get to my knitting machines upstairs and not sure if I can still get the carriage to go across the bed. Also I don’t have the flexibility in my fingerd nymore. So it seems like hand knitting may just be out of the question here soon. I can still crochet. Or do what I’m doing now surfing on the net.So if you are just in your 20’s, 30’s and just plain jealous because you couldn’t figure out how to make the modifications that this young (?) guy has done. Then I think you better just shut your mouth until you have something better to contribute to this site.In fact it seems to me alot of you are chewing on sour grapes. AT least he has used his BRAIN to help a friend.

The
Orbita mouse seems to be finally coming to production
. After watching that video, it seems that the mouse could be quite nice actually. We’ve seen several people
build jog wheels
for their computer and others try to
make scrolling more ergonomic
, and this product seems to add both decently. Well, it could probably be more ergonomic, but it is a start. At less than $100 it isn’t cost prohibitive either. The question is, have any of you built an alternative? Using a puck shaped device seems like it could get bothersome on the hand, how would you improve the design?

The main problem would be letting go of the ball and it rolls off the table, your mouse moves and then it clicks somewhere on your screen when it bounces on the floor. :)",

[rdagger] sent us this really well done
multitouch MAME cabinet build
. He ha penned to find a used, and fairly worn cocktail cabinet. The monitor was damaged, keys lost, and internals had been home to mice for some time. He promptly tore out the old guts, replaced the smelly mouse damaged base and began building the projection system. For touch sensing, he’s using a web cam with the IR filter removed to detect disturbances in some IR laser beams. We’re not completely clear on how he mounted the lasers, he skips over that part. There’s nothing groundbreaking in the technology here, we’ve done multitouch many times before. This project stands out in its execution. [rdagger] has done a fantastic job, the construction looks fantastic. Check out a video of it working after the break.

Adding another point creates orientation and distance.

Likewise, the scroll-wheel and the 5-button mice.@everyone else.What are the lasers for? are they part of the multitouch scheme or are they just there to look cool?",

"content": "generally for the mutlitouch, you need some way to track the location of your inputs(fingertips). some systems use scattering and discontinuity, by edge lighting a surface and having it deform with pressure, and some use reflectance with IR lights (what I think he’s doing here), and some others use IR light sources (all the wiimote white board versions).Basically, your finger is pretty much invisible to the camera until it disturbs the laser beam. At that point it is reflecting the IR light and the camera can pick it up. I’m not sure how he has this one set up, but we’ve seen similar styles in the past.Here is a good example:http://nuigroup.com/forums/viewthread/2109/",

The Maxim
DS2431 1K EEPROM
is
1-Wire
device that adds storage to a project using a single microcontroller pin. We previously interfaced a
1-wire thermometer
, but this EEPROM is slightly different because it draws power directly from the 1-Wire bus. Grab the
datasheet
(PDF) and follow along while we read and write this simple 1-Wire memory.
DS2431
1-Wire 1K EEPROM (Digikey #
DS2431+-ND
, $1.67)
We used our
Bus Pirate universal serial interface
to demonstrate the DS2431 EEPROM, we covered the proper connections and configuration options in
our previous 1-wire post
. The DS2431 requires just two connections: ground (pin 1) and 1-Wire/power (pin 2). Pin 3 remains unconnected. Like last time, we used a 2K pull-up resistor with the 1-Wire bus.
First, we use the Bus Pirate’s SEARCH ROM command to identify connected 1-Wire devices.

Found 0x03 devices.
The first 10 device IDs are available by MACRO, see (0).
1-WIRE>
The SEARCH ROM command reveals that there are 3 EEPROMs connected to the 1-Wire bus. The Bus Pirate stores the 64bit 1-wire addresses in macros so we don’t have to type it every time. We’ll work with the first device, identified by macro (1).
Writing to the DS2431 takes three steps:
Write data to DS2431’s 8byte ‘scratch pad’ EEPROM buffer
Verify the scratch pad contents and get the write access key
Copy data from the scratch pad to the EEPROM for permanent storage.
Command 0x0f writes to the scratch pad. The scratch pad is an 8byte buffer that holds data prior to saving it permanently in the EEPROM.

The MATCH ROM macro, (85), isolates the the first device, (1). 0x0f is the command to write to the scratch pad, followed by the start address, 0 0. Finally, we send eight bytes of data to save in the scratch pad. The scratch pad is eight bytes long, and all eight bytes will be copied from the scratch pad to the EEPROM at once.

To copy data from the scratch pad to the EEPROM, we must first retrieve a three byte access code from the scratch pad with the command 0xaa. The first three bytes are the access code (0x00 0x00 0x07), followed by the data contained in the scratch pad.

Command 0xf0 followed by a two byte memory address (0x00 0x00) begins the data read process. The first eight bytes (r:8) are the values we wrote earlier. Reads don’t involve the scratch pad and don’t have an 8byte limit, so further reads continue to the end of the memory.

[Matt] found, like many people, his Guitar Hero: World Tour cymbals left much to be desired. They were only detecting hits intermittently and starting to crack and fall apart as well. While he was waiting for his warranty replacements to arrive, he just couldn’t help by try to
make his own improved version
. Using about $25 worth of parts, mainly consisting of plastic plates and some neoprene material, he managed to make some pretty fantastic replacements. A video of them working might be a nice addition, but the writeup was pretty detailed otherwise.

The sensitivity is total crap – you have to WAIL on them to get anything above ‘minimum’ velocity, and lots of sporadic misses. This set is much like the xbox360 set, which *in my opinion* sucks more balls than imaginable.I can 5* most songs on expert, so I think I have the right to judge which sets are decent.I want to build some of these plate-cymbals just for look-see :D",

Geekware.ca has some ideas for
geeky tree ornaments
. This is a great way to add some personality to your holidays as well as recycle some of that electronic junk you have laying around. From RAM stars to floppy disk ornaments there are certainly some quirky ideas here. They would make great last minute gifts for someone who can appreciate your nerdiness.
GeekAlerts
also has a couple interesting ideas too.

Christmas has come early for us. This is our 3,000th post since launching Fall of 2004 doing just one post a day. The outstanding stat though is the 50,000 comments in the system. The team at Hack a Day would like to thank you, the readers, for bringing in all of our best
tips
and being part of this great community.

As the video above shows, [Zach Hoeken] is
continuing to improve on his
peristaltic pump design
. The moving parts in peristaltic pumps never contact the fluid being moved. Instead, they interact with the outside of the tubing that’s carrying the liquid. In [Zach]’s design, multiple skate bearings roll across the outside of the silicon tubing, squeezing the liquid through. You can get a better idea of how this works by
watching the first video
. The newer version appears to be pumping much better. We’re not sure if that’s because of faster motors or from switching to two bearings instead of three. This definitely looks like a good choice if you’re planning on building your own
cocktail robot
. You can find the plans on
Thingiverse
.

Capture the Flag (
CTF
) is a long running tradition at hacker conventions. It pits teams of security researchers against each other on the same network. Every team gets an identical virtual machine image. The VM has a set of custom written services that are known to be vulnerable. The teams work to secure their image while simultaneously exploiting services on the machines of other teams. A scoring server monitors the match as it progresses and awards points to teams for keeping their services up and also for stealing data from their competitors.
The Chaos Communication Congress in Berlin December 27-30, 2008 will
host a CTF competition
. Most CTF matches are done head to head in the same room. While 25C3 will have local teams, it will also be wide open for international teams to compete remotely. Remote teams will host their own images on a VPN with the other competitors. Now is a good time to register and familiarize yourself with the scoring system. It will certainly be interesting to see how this competition plays out now that teams that can’t make the trip can still compete.

How-to: Programmable Logic Devices (CPLD)

Complex programmable logic devices
(CPLDs) contain the building blocks for hundreds of
7400-serries logic ICs
. Complete circuits can be designed on a PC and then uploaded to a CPLD for instant implementation. A microcontroller connected to a CPLD is like a microcontroller paired with a reprogrammable circuit board and a fully stocked electronics store.
At first we weren’t sure of the wide appeal and application of CPLDs in hobbyist projects, but we’ve been convinced. A custom logic device can eliminate days of reading datasheets, finding the
ideal logic IC combination
, and then waiting for chips to arrive. Circuit boards are simpler with CPLDs because a single chip with programmable pin placement can replace
100s of individual logic ICs
. Circuit mistakes can be corrected by uploading a new design, rather than etching and stuffing a new circuit board. CPLDs are fast, with reaction times starting at 100MHz. Despite their extreme versatility, CPLDs are a mature technology with chips starting at $1.
We’ve got a home-etchable, self programming development board to get you started. Don’t worry, this board has a serial port interface for working with the CPLD, and doesn’t require a separate (usually parallel port) JTAG programmer.
Intro to CPLDs
When to use a CPLD
Consider using a CPLD when a design calls for more than one 7400 series logic ICs. A CPLD will be cheaper, faster, and can be programmed with your ideal pin-out configuration for simpler PCBs.
Use a CPLD in tricky designs that might require several iterations. It’s easier to design a new circuit in software and upload it to the CPLD than it is to design, etch, and stuff a new circuit board.
For maximum speed and instant response, choose a CPLD. The difference in speed is amazing; CPLDs start at a 100MHz, while microcontrollers respond to interrupts at a few MHz. CPLD designs form circuits that react to external stimulus, reactions occur almost instantaneously. A microcontroller executes code to react to events, even interrupt routines have comparatively high latency.
CPLD vs FPGA
FPGA
s are better known than CPLDs, but they share many characteristics. This analogy isn’t perfect, but we like it: where FPGAs are a reprogrammable processor core, a CPLD is a reprogrammable circuit board or breadboard. FPGAs replace microcontrollers, memory, and other components. CPLDs absorb logic ICs, and work well with a microcontroller.
Manufacturers
Altera
and
Xilinx
, the biggest CPLD manufacturers, are better known for their FPGAs.
Lattice Semiconductor
is another large CPLD manufacturer with less community following.
Atmel
makes
pin-compatible versions
of old industry-standard CPLDs.
If you plan to work at 5volts, your options are limited. Xilinx XC9500 CPLDs are still available as new old stock, but cost four times more than newer 3.3volt equivalents. Atmel’s
ATF1502 series
works at 5volts, but they don’t offer a free development environment.
At 3.3volts there’s more options, but new CPLDs increasingly have a core that runs at 2.5volts, 1.8volts, or lower. The Altera
MAXII
and the Xilinx
XC9500XL
series are probably the most popular 3.3volt CPLDs. Xilinx also makes the
CoolrunnerII
CPLD, but it only comes in a TQFP package and requires a separate 1.8volt supply for the core.
Packages
Most manufacturers offer one or two CPLDs in a hobbyist friendly
PLCC 44 package
, though this is starting to disappear. PLCC is an SOIC-sized surface mount chip with pins on all four sides. PLCC44 sockets are commonly available in through-hole and SMD versions. Unfortunately, newer CPLD families are starting to eliminate the PLCC package and offer only 44 pin and larger TQFP chips, such as Xilinx’s CoolrunnerII.
Development environments
Most manufacturers offer a free development environment that supports design entry using simple schematics, as well as
Verilog
or
VHDL
. Many won’t support the latest FPGAs in the free version, but we only need the CPLD parts anyway. Altera has
Quartus
, Xilinx has
ISE
, and Lattice has
ispLever
. Atmel has
ProChip Designer
for the ATF15xx series, but they only offer a 6month trial license — which they wouldn’t actually give us.
Programmers
The development board we present doesn’t need a separate JTAG programmer because the PIC microcontroller already programs the CPLD. If you want an external programmer, the cheapest are the parallel port programmers:
Parallel Cable III for Xilinx
and
BytleBlaster for Altera
. Inexpensive clones, and schematics, are available at SparkFun. The
OpenOCD
is a generic USB JTAG programmer that will work with many CPLDs, FPGAs, and ARMs.
Our choice
We eventually settled on the Xilinx XC9500XL series because it had a cheap development kit we could use to
test our JTAG programmer
prior to implementing an entire design.
The
DO-CPLD-DK
from
Digilent
includes a XC9572XL, a CoolrunnerII, and parallel port programmer. Nu Horizons has some
old non-ROHS models for $40
, but due to sloppy variable type handling in their credit card processing scripts, we couldn’t complete an order online. We tried to do it over the phone but they refused to take such a small order on the phone, even during a website malfunction. In the end, it was cheaper to pay full price at Digikey (#
122-1512-ND
) after including New Horizon’s exorbitant shipping charges. We wouldn’t normally mention this, but with only two places to buy the board it’s probably worth noting our experience.
CPLD development board
Click here for a full size schematic image
(PNG). The circuit and PCB are designed using the freeware version of
Cadsoft Eagle
. All the files for this project are included in the project archive linked at the end of the article.
Circuit
A PIC
24FJ64GA002
microcontroller (IC1) provides the user and programming interface to the CPLD. We use this $4 PIC in a lot of projects because the peripheral pin select feature makes board routing really easy. Check out our
introduction to the PIC24F
for more details. The PIC needs to communicate with a PC serial port, so we added an inexpensive MAX3232 RS232 transceiver. The serial interface should work with a USB->serial adapter.
Our choice of CPLD (IC3), a Xilinx
XC9572XL
(PDF), is connected between the PIC and several other components. We can create an endless variety of circuitry between the PIC and other chips using the reprogrammable logic inside the CPLD.
The PIC will program the CPLD with code sent from a PC serial port, but we still brought the JTAG pins to a header for easy external debugging.
A
DS1085 digital programmable oscillator
(IC4) generates clock frequencies between 8KHz and 133MHz, at 10KHz increments. This is very similar to the
DS1077 we covered earlier,
but it has even steps between all frequencies. The DS1085 requires a 5volt supply (VR2). The I2C interface also runs at 5volts, so we connected it to 5volt tolerant PIC pins. It’s possible to use the 3.3volt 66MHz 1085L instead, and remove the 5volt supply.
We used a cheap 3.3volt SOT223 voltage regulator (VR1) to power most of the circuit. The 5volt supply (VR2) can be excluded if you use a slower 1085L 3.3volt oscillator.
CPLDs are commonly used as a memory controller, so we included 32K of SRAM (IC5) on the development board. A 3.3volt latch with 5volt tolerant inputs interface the memory inputs to a wide range of external voltages (IC6). The latch inputs are held low with a 1Mohm resistor network (RN1). We’ll discuss this section extensively in an upcoming article.
PCB
The board is a quasi one-sided design. We made several compromises so we could prototype this highly experimental PCB ourselves. We present the board ‘as is’ for other die-hards that might want to etch this board at home. If you send the PCB to a board house, try to correct these issues prior to producing a ‘real’ double-sided board.
One power pin of the CPLD is missing a decoupling capacitor entirely; there was no way to put a capacitor in that area. One CPLD decoupling capacitor, and the SRAM decoupling capacitor, are through-hole parts. Using these through-hole parts eliminated a few jumper wires.
The jumper wires on the back of the board are optimized for single-sided production, rather than good design practices. We faked a double-sided board by soldering the power bus on the back. A real double-sided board design should route the power bus to avoid crossing signal paths, and include the missing decoupling capacitors.
We used an surface mount PLCC chip socket, but a through-hole version is definitely a better idea. We though the SMD version would be easy to solder, but it turned out to be a nightmare. We really wanted the CPLD to be on the front of the board for the coolest possible presentation. A proper two-sided board with plated through-holes can have a through-hole socket on the front, but this wasn’t possible with our 1-sided prototype board.

Firmware
The firmware is written in C using the free demonstration version of the
PIC C30 compiler
. Learn all about working with this PIC in our
introduction to the PIC 24F series
. The firmware is included in the project archive at the end of the article.
We wanted a super easy way to interact with the hardware on the board without endless compile-program-test cycles. We made a custom version of the
Bus Pirate firmware
that provides a simple ASCII terminal interface to the DS1085 clock chip (I2C), the CPLD programing interface (JTAG), and a 3 wire (SPI) interface to the CPLD. Check out the Bus Pirate tutorial for background on the simple syntax used with the firmware.
The original Bus Pirate firmware handles several protocols that share the same pins. For the CPLD version, we changed the pin assignments to fit the connections on the development board. We also removed unused modules and options.
CPLD blinky LED examples
We prepared several designs in Xilinx’s ISE development environment. The schematics, pin placement files, and compiled designs (XSVF) are included in the project archive linked at the end of the article. A full explanation of ISE is beyond the scope of this article; we found the help files sufficiently useful to make these examples.
The first design simply lights the LED connected to pin 8 of the CPLD.
Prepare the XSVF file
XSVF is a compressed JTAG programming format, as described by Xilinx in
this application note
(PDF). XSVF isn’t limited to programming Xilinx devices, and can be prepared for any chip that provides a common
BSDL
JTAG definition file.
Open the iMPACT programming tool from the ISE Design Suite project panel under
Configure target device->iMPACT
.
Choose the option to
create a boundary scan file
, and set the type to XSVF.
Give the XSVF output a file name and then add a compiled CPLD image (ex1.jed) when prompted to add a device.
You should see a JTAG chain that contains a single device.
Click on the device and choose program; iMPACT will record the programming sequences to an XSVF file.
With XSVF file in hand, it’s time to open up a terminal and program the CPLD. We like
Tera Term
and
Hercules
on Windows. You
must
enable XON/XOFF flow control in the client to use the JTAG interface. The default PC side setting for the development board terminal is 115200bps, 8N1.

In the terminal we enter the mode menu (m), and choose JTAG (3). Macro 2 probes the JTAG chain, in our case this is just the CPLD. The chain report tells us that the chip is connected and responding.
Read more about the JTAG interface
.
Now we can run the XSVF programmer, macro (3), and upload the XSVF file from the terminal
in binary mode
. The first example just lights the LED on pin 8. If the LED lights, we can verify that programming was successful. If your LED doesn’t light, don’t despair; sometimes the JTAG programmer sticks and a reset macro (1) will get the chip going.

74LS32/4071 OR gate, blink at half rate (/2)
A major component of the CPLD development board is the 1085(L) frequency synthesizer connected to pin 7 of the CPLD. The next example uses a
logic OR gate
, like a
74LS32 or 4071
IC, to blink the LED whenever the clock signal is high. At even the slowest clock rate the blinking will be too fast to see, but we should get a nice PWM dimming effect compared to the first example.

The DS1085 is almost exactly like the
DS1077 we covered earlier
, but has a DAC controlled oscillator for even steps between all frequencies. We programmed the clock to the slowest frequency using the commands shown above. The LED is dimmed by the pulse-width modulation effect of the clock signal.
LED at half brightness.
74F269 16bit synchronous counter, blink slowly (/
65535
)
We just programmed the CPLD with a logic OR gate similar to a 74LS32. Now, we’re going to reprogram the chip with a 16bit counter like two cascaded
74F269s
. At $1.15 each, two 74F269 Ics are more expensive than the XC9572XL CPLD. A 16bit counter rolls over once per 65535 ticks, so a LED attached to the last bit will toggle once every 65535/2 ticks.
Now we can see the cool part of CPLDs. The CPLD is like a programmable breadboard; we just popped out the 74LS32 and put in a 74F269, without buying parts, reading datasheets, etching, wiring, etc. A microcontroller connected to a CPLD can reconfigure its own circuit board to fix errors, add features, or re-purpose it for entirely different applications.
We upload the new design as before, but now the clock is divided by 65535 and the LED toggles about once per second.

Taking it further
Next time we’ll look at discrete 7400-series logic chips, and implement a ton of them in the CPLD to make a high-speed bus sniffer and logic analyzer.

The ones on my shelf are _Verilog Quickstart_ by James Lee (an old ham radio buddy) and _FPGA Design with Verilog_ by Ken Coffman.Don’t forget to check the manufacturer’s website for their docs as well. They have excellent tutorials and lists of the tips and tricks you need to know when working with each part (how to configure outputs, master clear, global clocks and all that stuff).Start off with something simple, like a state machine to control some LEDs and move on from there. I found the hardest thing to get my head around was writing code that looked like C, but had much different rules for how it executed — all at once! It helps to think of the code blocks you write not as code, but as physical blocks in a circuit, which is what they will become.Don’t overlook the built in simulator!

Xbox 360 Jasper In The Wild

[Ben Heck] has written up what he calls a “super unboxing” of the new
jasper Xbox 360
. The “jasper” refers to a
new graphics processor
that is supposed to be smaller and more reliable. They have been hard to find, but [Ben] shows us how to spot them. Simply look at the sticker on the back of the unit that shows voltage/current. If it uses 12.1 Amps instead of 14.2, it has the jasper.

I got it because my friend replaced his dead original 360 (which is now mine) with a Falcon Arcade model but kept his original power brick, having only the new brick and an RRoD console I didn’t want to invest money in a new brick, so hacking the newer one worked fine.",

This

because, well, why not? Part dog, part motorcycle it walks/drives and breathes fire. Constructed from all salvaged parts, this thing is a testament to recycling. Either that or it is the harbinger of the robot apocalypse. Regardless of the possibility of it enslaving all mankind, we want one. Be sure to

The Hemp-Mote

"wii",

We’re sure that almost every one of our readers has been wondering why they can’t have a hemp covered Wiimote. Well, [Dhreck] got tired of waiting and
made one himself
. This isn’t just as simple as covering a Wiimote with hemp chord. Major modifications had to be made to keep it from getting too bulky. [Dhreck] whittled down most of the shell, then re formed it with modeling putty. After sanding that nice and smooth and applying a nice black paint job, he started the painstaking process of wrapping it in hemp. It still works perfectly fine, but can fray if you are too hard on it. So, if you get your hands on some hemp, take it easy on your Wii.

Cold Heat soldering irons are pretty cool. They heat up in seconds and cool down just as quickly. [photozz] shows us how we can
make one from stuff we probably have sitting around
right now.
Cold Heat soldering irons
work off of resistance, the tip material heats very quickly when electricity is passed through the two halves. Upon assessing what he had lying around, [photozz] realized that graphite would work much the same way. He modified a regular soldering iron with a new two piece graphite tip, and powered it with an old pc power supply. The end result is quite nice, though it still needs some kind of temperature control. You may recall seeing other electrical uses for graphite, such as
making quick and dirty light
.

There are special spot-welders that deliver high temperatures to a very small point that are intended for this.It seems like the cold heat iron might also be able to do the same thing by heating the terminal very quickly, limiting the time that the heat has to conduct through metal pieces to the plastic parts.Any thoughts?

"content": "I have a coldheat, and I have found that it is a lot better with nimh batteries. The instructions specifically say not to use them, and they will probably damage the tip or some internal circuitry, but it is worth it. Nimh batteries can supply extra current, so the tip heats up faster and gets hotter, making it easier to get a good joint. Eventually the tip will start to glow red and the plastic that holds it will start to melt. You should stop before that happens. Also, since the tip gets hotter with nimh batteries, it will not cool down as fast, so be careful not to burn youself.To comment on the lead light, I found a way to get much brighter, whiter light. I used a PSU at either 5V or 12V (I can’t remember). I connected the ground wire to a penny, then connected a positive wire to a short piece of lead using an alligator clip to hold the lead. The lead should be abut 1/2″ to 1″ long for the most light. To use it, gently press the tip of the lead against the penny. Most of the light will be made near the tip, so as the graphite burns away you can feed the lead towards the penny and get consistent light. It works kind of like an arc welder or maybe an arc lamp (but I don’t think there was actually that much arcing). The penny acts as a reflector so you don’ blind yourself and it helps to concentrate the light. It would be really cool if there was some way to autofeed the graphite and make a usable lamp.",

Here’s an update on our
earlier post about genetic programming
. Altered Qualia has
posted a new implementation
of [Ron Alsing]’s idea. It starts with 50 polygons and then randomly changes one parameter with each optimization step. If the the change results in fewer differences from the target image, it’s kept as the new best DNA. This search method is similar to
simulated annealing
. The image above is the result of 1500 good mutations out of 35900 possible. The implementation lets you choose any image, but smaller means the fitness calculation is faster. It’s written in JavaScript using the
<canvas>
environment. You’ll definitely get better performance using
newer browser builds
.

If you keep randomly changing points of the polygon eventually you will end up with something similar. How do you decide the coloring or is that random too? Why doesn’t the program learn and evolve leaving out any interaction other than the input of an image? Then spit out the final best fit. The term genetic programming is used quite loosely here. What is the environment that the program is in? How does it evolve? This is basically randomizing polygons until you get a best fit image by eye.",

Differences are summed and a smaller total is better. A mutation is a random change to either one pixel or the color of a single polygon. As to whether it’s GP or not, you’re entitled to your own opinion. The author says: “I will claim that this is a GP due to the fact that the application clones and mutates an executable Abstract Syntax Tree (AST). Even if the population is small, there is still competition between the parent and the child, the best fit of the two will survive.”",

WordPress 2.7
has
just been released
and features a complete interface overhaul. Hack a Day runs on
WordPress MU
hosted by
WordPress.com
, so we got this update last week. We run standard WordPress.org on all of our personal blogs though. We recommend it because it’s free, has a massive userbase, and if you host it yourself, you can do whatever you want with it.
To make the upgrade process as simple as possible (and for the
sheer rush of ‘rm -rf’
), we use a one line command.
$ curl
http://wordpress.org/latest.zip
-o "wp.zip" && unzip wp.zip && rm -rf ./wordpress/wp-content/ && cp -r ./wordpress/* ~/www/
curl
downloads the latest version from wordpress. unzip unpacks all of the files into a directory called ‘wordpress’. rm -rf removes everything in the ‘wp-content’ directory. Otherwise, you will overwrite your images, themes, and plugins. cp -r copies everything to your http document root, overwriting the previous install.
Naturally, you should
back up your current install and database
beforehand. We tend to use the one-liner with reckless abandon. If you’re wondering about the terseness, it was designed to
fit inside the 140 character limit of Twitter
.
[Thanks,
Chris Finke

[PuffMag1cDrag0n] shows us how to make a
fairly simple projected LED display
. The projector is made from a 13×7 LED matrix and a couple
fresnel lenses
. The layout and construction is similar to the
Lumenlab projector setup
, only replacing all the lighting and LCD with an LED array. It communicates via serial port and is powered by a pic micro 16f648. We would love to see an RGB version of this. The directions are a bit rushed, but you should be able to get the gist. Just remember that you need some pretty powerful LEDs to throw a big image.

We couldn’t make Roboexotica in Vienna, Austria this year (check out
last year’s coverage
), so we asked
[Bre Pettis
] to act as our liaison.
Last night was the opening party of
Roboexotica
, the worldwide gathering of cocktail robots. It was a blast! Pictured above is
Robovox
, a 40 foot high robot that you can text message to and it will say what you text to it!
I was running my robot arms as a competition,
armatron
style, to get cherries into a shot glass.
The Reprap that Marius, Philipp, and the gang over at
Metalab
made last year that failed was
revived
and cranked out shot glasses all night!
Here are
my photos
.
More photos tagged Roboexotica
are coming in all the time, stay tuned!

[Ben Heck] posted an interesting one-off project he built many months ago. Video game developer
Infinity Ward
approached him to build a large display that indicated
what buttons on a controller were being pressed
. They were planning on using it during player testing by recording the board and the monitor at the same time. They could then compare the two to see if there was any disconnect between the players input and the onscreen action. Infinity Ward is the developer behind games like
Call of Duty 4
.
[Ben] piggy-backed the switch connections and added an external port. He used a pair of octal buffer ICs to replicate the signals and activate the LEDs. The whole board is powered by the same 3.3V line that’s used by accessories like the chat pad. The triggers have three LEDs each and are lit using a
resistor ladder
. [Ben] comments that since this is a newer Xbox 360 controller, the active-low button scheme makes it fairly easy to work with. There is a video of the board embedded below.

[Stephen Myers] has been toying around with some beta ioBridge hardware. He decided to build a
remote control dog treat dispenser
.
ioBridge
‘s hardware is built specifically to make web enabling projects easy. The main controller board has four I/O channels that speak to addon modules. It has an ethernet port on the main board and an easy to configure website.
[Stephen] used a servo addon board for his project. The dispenser is built from a scrap CD spindle attached to a servo. He can issue commands from his iPhone, which shows live video of the kennel. He’ll be building several other automation projects based on this system.

We really aren’t sure what the statement is here. This is one of the
displays at the MuTate London Exhibition
. There is tons of stuff to see there, from interactive displays to giant art-piece vehicles. This specific display seems to have garnered the most attention though. we can understand the megaphone headed flailing DJ, but what is with the CCTV camera heads?

Approved doors for the building were expensive, so the landlord put a notice on everyone’s door that read something like this. “If you see someone propping the door open, report them. If you do not know their apartment number, follow them and get it. There may even be a reward if we can find out who keeps propping the door open!”. I’m sure people tried to find out who it was. I wasn’t a smoker, but with that type of thing going on, I couldn’t help but feel like everyone I ran into in the hall might be reporting my actions. Maybe it means that everyone is a tool, or at least could be. Maybe the people who made it felt “watched” even when they are kicking back at the ol’ strip join?",

[mikamika] has put together a great tutorial on
how to build this musical shirt
. The whole process is covered, from taking apart the toy keyboard to laying out the circuit and creating the fabric switches. He used the same method as [plusea] for the
fabric buttons
and conductive thread for most of the connections. It seems as though he has actually taken [plusea]’s
wearable shirt project
and added some polish. His looks good enough, he might even be able to
make it through an airport
.

SparkFun’s latest tutorial shows you
how to work with relays
. A relay is an electrically operated switch. In this case, they’re using it to switch a 120V AC outlet. The article carries the standard warnings about how not to kill yourself with AC (plus some non sequitor linking throughout). As an extra precaution, they chose a GFI outlet. You probably know how a relay works, but it’s worth seeing how they implemented it. They use a transistor to prevent overloading the microcontroller’s GPIO pin. The control pin is pulled to ground to keep the relay off. A diode is placed across the relay coil to manage the power flow when it discharges. An indicator LED is included to show when the relay closes. This is a great foundation for an automation project, or maybe you just want to
terrorize your cat

"content": "Relays and other ‘electromagnetic’ things require some way to deal with the back-emf (‘flyback’) that results when the forward current is turned off.This is the reason for the diode when forward current is switched by a transistor.This is the reason for the capacitor in ‘points type’ automotive ignition systems. The capacitor delays (slows-down) the ‘flyback’, to give the ‘points’ time to open. Without the capacitor, the inductive energy will be dissipated at the points as ‘arcing’, not the spark-plug. The separate capacitor lowers the resonate frequency of the coil (and stray capacitance). [A low value resistor in series with the external capacitor is a good idea that will prevent momentary over-current as the coil is energized.]The higher the flyback voltage is allowed to go, the sooner the ‘flyback’ energy will dissipate. The volts X amps product (the flyback energy) is fixed (and equal to the forward energy used to ‘charge’ the inductor).External components can limit the flyback voltage (e.g., diode, Zener), or delay its voltage rise (e.g., capacitor), however will reduce the total energy.A single (Si) diode limits to 0.7 volts or so, and assures a relatively slow discharge of energy. Faster, is to let the reverse voltage go as high as possible (with due regard to the voltage rating of the switch, transistor, etc.).A capacitor will ‘slow-down’ the flyback and reduce its peak voltage, but will ‘absorb’ no energy, so the combination will ‘ring’ until the energy is dissipated in the resistance of the circuit.As regards relays for load control in systems such as you describe…Such systems require the ‘computer’ be on at all times the relay is to be energized. In addition, power to energize the relay must be available when needed. This seems less than optimal…Since controlling a light and many other loads, requires just one ‘bit’ of memory, why not use a relay that is a ‘one-bit’ (mechanical) memory in addition to its switching function?For this purpose I suggest either an ‘alternate-action’ or a ‘mechanically latching’ relay.Each time the single coil of an ‘alternate action’ relay is energized and released, the contact ‘state’ is changed.Each time a ‘latching’ relay, is energized and released, the contact ‘state’ will be determined by which coil was energized (of two).The more versatile of these relays will actually change their contact(s) position when the coil is de-energized.Such relays can be controlled by a computer pulse or by manual switches (of type SP3position, center-off). If an auxiliary SPDT contact set is provided, the relay can be energized to a ‘guaranteed’ turn-on (if it is off), and vice-versa, with such a switch. Since this is ‘normally open control’, as many switches (and computers) as needed can be wired in parallel.A person can determine if the relay needs to be ‘toggled’ by observing the load. A computer cannot do this without aid, so some means is needed to permit the computer to sense the ‘state’ of the load. Simplest is to use ‘auxiliary contacts’. ‘Auxiliary contact’ are less than optimal because they report the relay ‘command’, not what the load is actually doing.Better is to sense both the voltage across, and the current through, the load. With this information the computer can actually ‘know’ what the loaf is doing.When using ‘alternate action’ or ‘latching’ relays, the computer and/or power source can be shut-down (or fail) without affecting the ‘state’ of the relay (and load). In addition, manual control of the relay is possible with or without the ‘consciousness’ of the computer, however a power source to ‘pulse’ the relay is needed.If a means of controlling the load when no relay energization power is available is a requirement, a SPDT relay power contact can be used with a manual SPDT switch (this is the usual ‘two-way’ light switch hookup in residential wiring).If a second manual control switch is needed, a DPDT switch wired as a ‘reversing switch’ is needed. As many of these ‘reversing switches’ can be added as needed. This is the usual ‘three-way’ (or more than three ways) light switch hookup in residential wiring.)The load voltage and current sense (if provided) should always measure what is actually seen by the load, particularly when the load can be controlled separately from the computer.Relays provide one other feature than makes them particularly suited to many applications, This is the ‘galvanic isolation’ between the coil and each ‘set’ of contacts.AC and DC current sensing with ‘galvanic isolation’ is easily provided by using magnetics and the Hall-effect.Voltage sensing with galvanic isolation is more difficult, but routinely done in industrial controls.AC Voltage sensing can be done with a small ‘potential’ transformer.DC voltage sensing can also be done with a transformer — if the DC voltage is ‘converted’ to AC by use of ‘switches’ (actually transistors). The transistors are ‘driven’ with second transformer. If MOS transistors are used, the AC voltage output can be ‘synchronously rectified’, and will accurately ‘track’ the input DC-voltage over a wide range. (Due regard must be paid to the ‘switching time’ of the transistors and transformer!)(Long comment — sorry)",

"content": "At first glance this item seems trivial, and I wouldn’t bother to comment except that a number of statements are misleading, wrong, or significantly incomplete.“Inside the relay are two paddles made of metal. One paddle is made of a ferrous material like steel and is free to move. The other paddle is made of copper and stationary.”The moving “paddle” is actually called the armature (as it is in motors) and carries the moving relay contacts.These contacts can be made of many different materials depending on the intended service of the relay – plain copper, silver, gold flashed, silver-cadmium-oxide (“Silcadox”), mercury wetted, etc. Using the wrong contact material can result in very short contact life (e.g. gold flashed on high current), or failure to conduct when closed (e.g. Silcadox power relays on low voltage).The relay stator, or bobbin core, is also a ferrous material, *not* copper. There are relays that are intended for AC coil operation and these have a split pole which has a copper “shading” ring around one of the split poles (producing a phase lag and thus a net magnetic attraction).“The paddles are capable of carrying very large currents. Both AC or DC – the paddles don’t care.”They do actually. Relay contacts typically have two ratings, AC and DC, and the DC rating is typically only one-fifth to one-tenth of the AC rating. As mentioned above, contacts switching DC often need additional treatment to reduce contact arcing and resulting damage.“If you need 10A@120VAC, don’t use a relay rated for 10A@120VAC, instead use a bigger one …”A relay rated for 10 amp AC operation will give its rated switching life (e.g. 100,000 operations) switching that current. A key point is that the current rating is for a purely *resistive* load and the contacts must be significantly de-rated for reactive (typically inductive) loads.Don’t forget that lamp loads may be resistive but they also suffer from cold inrush currents from five to twenty times rated current that may cause relay contacts to weld and stick.Note also that solid-state relays and triacs are also prone to “stick on” when used with reactive loads and may require load-side power-factor correction to operate correctly.“The 1N4148 diode is connected in a odd fashion for a reason. This is placed between power and ground in a reverse fashion.”Actually it is placed across the relay *coil*, and should be as close as possible to the relay to avoid EMI to surrounding circuits.“the 1N4148 will forward bias causing the current stored in the coil to flow happily back to the 5V rail protecting the power supply and the near-by parts.”Now things start to get tricky. The object of this “catch” diode is to prevent damage to the driving transistor by shorting the coil back-emf. While just about any diode will serve this function there is a gotcha in that all diodes have a turn on time, and during this time the voltage may still spike to several kilovolts.This won’t kill the transistor because the duration is very short and may require a 100+MHz CRO to see, but it can still cause connected logic systems to malfunction/crash. The classic is the 555+relay that won’t time out, being retriggered by this spike. Adding a snubber of say 0.1uF in series with 47 ohms across the relay coil and diode will fix it.It should also be noted that anything that suppresses this spike will also extend the relay release time by a factor of ten or more.“Note: A two-wire extension cord will not work correctly. Notice we are using thick, three-wire circular extension cord. This extra wire is the ground return and allows the GFCI to operate correctly.”This is a typical misunderstanding of how an earth leakage breaker (GFCI aka ELB/core-balance relay/Safety Switch) works – an earth is *not* required on the load side, but is *vital* on the supply side.Note well that if you happen to be insulated from local earth by your shoes, stool, or mat, and happen to touch both active and neutral an earth leakage breaker *will not* save you – you are just part of the load.An earth leakage breaker is your *last* line of defence, not your first – *always* *unplug* before tinkering lest you log out forever.“The goal here is to ‘tin’ the three wires.”Wires intended for clamp connection should *not* be tinned as solder cold-flows under pressure and reduces the clamped pressure over time, worse with thermal cycling. Lead/tin solder also causes copper to embrittle, leading to fracturing where the tinning ends – significant where the assembly is subject to vibration.“Removing CTRL from the 5V rail (called floating because the CTRL line is neither connected to 5V or GND), …”This is emphatically not “floating” as the control signal is referenced to the relay coil supply. To be truly floating something like an opto-isolator is required.Relays may be old hat but they are still perfectly valid components in the right application, and like any component they require some understanding of their characteristics to avoid problems.",

The 25C3 team has a post
highlighting some of the hardware workshops
that will be happening at Chaos Communication Congress this year. Our own [Jimmie Rodgers] will be in the
microcontroller workshop
area building kits with many others. The folks from mignon will be
bringing several of their game kits
for another workshop. We saw quite a few
quadcopters at CCCamp
and the team from Mikrokopter will be back to help you
construct your own drone
. They say it only takes five hours for the full build, but space is limited.

You’ve probably seen
musical Tesla coils
already. People have wired them up to computers and keyboards to make them serve as dangerous and awesome speakers. This video popped up of someone
playing his guitar through one
. It is rough, and not very good at
polyphony
, but still cool. We would like to see several coils, split by different filters to be able to hear more of the guitar chords. If only someone had rigged these up for Queen when
Flash Gordan
was made.

PS2 Controller Thermometer

Finding themselves in need of a thermometer that could communicate with the computer, The Cheap Vegetable Gardener resorted to a bit of hacking. They created this
PS2 controller thermometer
by attaching some thermistors to the analog stick inputs. Each PS2 controller could collect data from up to four thermistors. There is an auto shutoff feature built into the controller that shuts off the analog signal after a period of non use. To overcome this, they simply taped the L2 button down.

Given some decent soldering and wire you should be able to get a good 50-100 feet though would definitely recommend the shorter the better.",

Those usually digitize the buttons since windows doesn’t support them. However, if you went with an XBox pad, which is basically the same but natively USB, a custom driver (Google “redcl0ud” or “libusb win32”) could retrieve any/all analog inputs.",

OpenSound Control
protocol is an emerging standard for communication between musical programs. It’s meant to replace MIDI. The DSMI, DS Music Interface, team has just added support for OSC. You can now use your DS as
generic OSC music controller over WiFi
. OSC has TCP/IP support built in, so there is no need to run a host sever to talk to DSMI like you did when they only supported MIDI. We’ve seen OSC used in other projects like the
monome
. It’s also the basis for the multitouch communication protocol
TUIO
.

Our recent
netbook post
got a huge response. They are almost unanimously loved. A few
dissenting
opinions
were present though. A few people mentioned that until this generation arrived, they were buying used subnotebooks for exactly the same reasons.
If you’re in the market for a new machine,
Obsessable’s netbook comparator
has all of the current models broken down by feature.

Transmeta crusoe, 6″ xga lcd, 1gb ram, 1.8″ pata hdd and usb 1.1. its about two thirds the size of this acer one. It cost about $1400.Things are getting better, but they are not even close to perfect yet.If HP could get the aesthetic/build quality of the mini note, with the atom + discrete gpu combo on some next gen chipset for $500, that would be nice.I don’t know if the market would bear it though.I’d never pay $400 for this machine but I will admit it has a place.

It also had a non-backlit mono display, and a text-only interface, using a special modified DOS. It also used standard AA batteries, which could power it for over 2 weeks! There was no “internet” in those days, but it could connect to a BBS (google it!) with its primitive modem which, if I recall correctly, used sounds from the speaker to dial and connect using a regular telephone handset. (I tried, but was never able to get it to connect over my old Motorola “brick phone”.) It was pretty cool in its day, but alas, I lost mine when I put it on top of my car and drove off, and never saw it again….I just bought an MSI Wind U100 to replace my Acer Aspire One that was stolen after I had it only 3 months. Both are great machines, serve their purpose well, and are inexpensive, even compared to the “original netbook” eeePC. Sadly, the concept of the netbook has been co-opted to being just a inexpensive mini-laptop, and not really true to the original concept. The original concept was, (at least as it appeared to me to be) a SMALL, CHEAP, DURABLE device that cold be used to surf the internet, create and edit office docs, and maybe play some media files. There are some new ones coming soon, such as the HiVision $98 netbook, which very much resembles the original eeePC. While I am enjoying my new MSI Wind, I will probably get one of these also.",

[Garrett] from macetech has been prototyping shields for the Arduino development platform. Arduino’s have an inexplicable nonstandard spacing between two of the banks of output pins. This means that you can’t use regular perfboard with them. To make the design process quicker, [Garrett] has
put together an Eagle file
that just includes the male header pins. The file also has a line indicating the tall lower board components so you can avoid creating shorts.

Track The Sun For Home Lighting.

Have a room in your house that really could benefit from some sunlight? Build a
Suntrack
to reflect light in as long as possible. The two axis motor set up is built from a couple of satellite dish positioning motors with the control electronics removed. The whole thing is controlled with a PIC 18f2520. Once calibrated, it will reflect the sun into your room, updating every twenty seconds. While this may not be the most efficient way of lighting a room, it is a cool way to do it if you absolutely must have sunlight. We can’t help but wonder if there would be a way of using a solar powered system to do this to save energy. Could this possibly be done using
BEAM
“
head
” circuit?

The whole thing could be powered from a local battery charged by a tap off one of the PV panels. We only built one degree of freedom into the mounting system, since it was destined for arctic latitudes where inclination wasn’t as much of an issue. It would track the sun from sunrise to sunset, then reset to its start position when both cells went dark.

22″ Binocular Telescope

This is the
worlds largest known visual binocular
. Why binocular and not just a regular telescope? Well, it all has to do with clarity. Apparently when you can use both eyes, you can see much more detail and pick up light better. The author states in
one story
that he was able to see a spiral galaxy clearly with a binocular telescope, but couldn’t see it at all with a monocular telescope of the same power.
There is information on several models on the site. Look in the right hand column as well for useful links to parts distributors.

But the acuity is just as great if the resulting light beam is split and fed equally to both eyes by a beam splitter than if two separate mirrors are fed to your eyes. Yes, there is a 50% (actually slightly more, due to losses) decrease in light intensity, but that’s only a difference of about 0.75 magnitude. You could gain that back by building a 30″ telescope instead of a 22″ scope, and you’d get better resolving power and a simpler optical path as a result.Binocular telescopes, while cool, are kind of a stunt.",

A binocular telescope is better at removing this distortion because it uses two separate parallel sources of light. Computer algorithms adjust the shapes of the mirrors and use the images produced by both to obtain a clearer image (with less distortion).Obviously, the Hubble space telescope was designed to avoid the problem altogether – it does not have Earth’s atmosphere to contend with.One can only assume that the producer of the telescope pictured in this article gains some of the benefits of the reduction of atmospheric distortion that these kinds of telescopes provide.

[Ron Alsing] wanted to try out some genetic programming, so he created a simple test problem: Could you
render the Mona Lisa using just 50 semitransparent polygons
? The program starts with a random DNA sequence. It then mutates and compares itself to the original image. If the mutation is closer, it becomes the new sequence. The final image he shows looks pretty good after 904,314 iterations.
[prunesquallor]
pointed out
a genetic algorithm project of his own. It’s a flash program to
evolve a car
. The car tries to get as far as possible on a set terrain without the passenger circles hitting the ground. The wheel size and positions can change along with the spring length, constant, and damping. A graph tracks the best performance along with the mean. He’s planning on building a version that lets you change the parameters.

This is to show how the organisms that survive are the best suited to their environment and that they get to pass down their genes (their DNA). Nothing more. The whole point about it taking so long to get to the solution is a talking point on its own. It takes a bloody long time for an organism to evolve to perfectly suit its environment!

They might, in fact, carry the necessary codes to reach Mona Lisa perfection.Another interesting twist would be to set up a mating system where a child can have not two parents, but three. I would think this would offer the potential advantage of faster evolution, but also the potential disadvantage of wider feature excursions. (The latter exposes the offspring to the risk of extinction.)",

They’re good when you can’t easily get a derivative of the value of a given solution, and have more than a couple continuous parameters to vary.

What if at frame 300,000 the circumstances changed and required the final picture to be The Starry Night? And wouldn’t you say that the evolution of the human body would be more like the complexity involved in a work on the magnitude of the Sistine Chapel? Here’s my point, climatology shows that the Earth occasionally undergoes dramatic (sometimes abrupt) changes in environment. If the Genetic Programming model is representative of evolution, how long would it take the program to adjust to the change?I guess my points are two-fold:1. The program presented here suggests there be a final design goal. The cross connection is that life on Earth is evolving towards an increasing level of complexity with a final goal in sight. The problem with that theory is that given time and left to their own devices, don’t systems move from ordered to less ordered?2. The program presented here lacks the complexity needed to represent the systems working together to result in life on Earth. If you were to take into account variables like climate, natural laws (organisms developing to thrive in our atmosphere, with our level of gravity, with our level of solar radiation, etc), species interaction, the program would be much more complex. It would be more like 10 or 20 different programs evolving separately and in conjunction with each other to result in something like the complete architecture of Rome.",

[kap4001] built what has to be the
simplest laser scanner possible
. It’s two servos strapped together with zip ties plus a 5V laser module. They’re connected to a
Pololu serial servo controller
. The laser is pulsed by switching the DTR line. You could use it to draw images like the one above… except that’s an
85 second exposure
.

You can modulate cheep laser diodes at 10khz no problem (the expensive ones go into the tens of ghz) which is more than enough for simple work like this.Also, you can greatly simplify your work by starting with the print head out of a laser printer (although it would be a good idea to swap the diode out for something a little more visible, the ones out of a dvd-r are fast bright and singlemode), which has the rotating mirror and will give you a sync signal to keep everything aligned. Then you only need to rotate a long first surface mirror (that was probably in the laser printer print head, but you could probably find a lighter one in a scanner) to do the y scanning. You could probably get away with using a servo for that axis (as long as it is a fast one), but a piece of polished hexagonal rod on a stepper motor would be a heck of a lot better.With that you should be able to create a screen that can scan about million pixles/second, maybe 10 million if you are good with analog design.

My DPSS using crappy TTL modulation can do over 40kpps. You are going to hit the limit of the scanners and/or microcontroller long before blanking becomes an issue. I have an arduino driving my scanner right now and the biggest bottleneck lies within timing issues.Ruby lasers are so early 70’s.Real men and women actually use argon/ion lasers with PCAOM’s. This is changing as DPSS lasers are becoming increasingly powerful at far lower costs. An entire RGB DPSS setup with over 1 watt output is half the cost of even a crappy PCAOM and can do far more colors, much faster.The comment on stepper motors reaching a scan limit is true, but nowhere near in the speeds of this application. Symbol handheld barcode scanners use(d) steppers with no issue. Actually there is a guy on ebay who sells salvaged ones exactly for this purpose. Operate them unipolar and use the other windings as a damper and you get very close to what actual galvos are. Granted don’t expect them to be cambridges or anything but on a budget using an audio amp and the most basic of DAC’s you can do some nice beam shows with them.",

Google has new program to sell Android phones directly to developers. The
Android Dev Phone 1
is both SIM-unlocked and hardware-unlocked. SIM-unlocked means you can use it on any GSM carrier you want. Hardware-unlocked means you can run
any system you want
on the phone, not just officially signed ones. No more need to worry about security patches
taking away your root access
.
The device is $399. You will need to purchase it through the
Android Market
as a registered developer (a $25 fee). We wonder how long before the unsigned bootloader starts getting flashed to
T-Mobile phones
.
Two new Android phones have surfaced recently which may prove just as friendly: the
Kogan Agora Pro
and the
QiGi i6
.
UPDATE:
While shipping is free in US, it is
incredibly expensive
everywhere else. Yes, we bought one.

Controlling a robot simply by looking at your desired location
is pretty freaking awesome. A web camera pointed at your face, analyzes your movements and pupil direction to send the bot signals. Look at a location and the bot goes, change your expression to send other commands to the bot. This easily surpasses the
laser guided assistance droid
for ease of use.

The
Nintendo keyless entry system
will vigilantly guard your door from intruders. Enter the right code and you get access, enter the wrong code and it will deny you and take your picture. [action_owl] did a fantastic job on this lock, using mainly recycled parts like an old CDRom and an
Arduino
. It works both with or without the computer. If you choose not to use the computer, you don’t get pictures of the people who entered the code wrong.
We like this project, but we feel it needs to be pointed out that this lock is pretty useless. Everyone already knows the code to get in is
UP, UP, DOWN, DOWN, LEFT, RIGHT, LEFT, RIGHT, B, A
.

If you can get through the cell phone text speak, you’ll probably enjoy this cool tutorial on how to
build a cell phone controlled robot
. This bot decodes the key tones, similar to the automated phone systems we’ve all experienced. It uses a chip called a MT8870
DTMF
decoder to translate the signal for the Atmega 16 controller. The circuit diagram is pretty hard to read, maybe we missed a downloadable one somewhere. The source code is available.
It would be nice to get some feedback from the robot, so you aren’t driving it completely blind. This is similar to the
Lego cell phone rover
that we showed you before. Next, he should make it recognize voice commands.

Dallas/Maxim’s
1-Wire
protocol is the most requested addition to the
Bus Pirate
. We finally got some 1-Wire parts, and today we’ll demonstrate the
DS1822 1-Wire digital thermometer
. Grab the
datasheet
(PDF) and follow along.
This post is accompanied by release v.0d of the Bus Pirate firmware for hardware version 0. This includes the new 1-Wire protocol library, more configuration options, and other improvements.
DS1822
Economy Digital Thermometer (Digikey #
DS1822+-ND
, $3.87)
We found a footprint in the 1-wire library for
Eagle
on the
Cadsoft download page
.
The 1-Wire protocol uses a single wire for data transfer, and sometimes power. Data is transferred in
time-sensitive ‘slots’
because there isn’t a separate clock to delineate bit periods.
Bus Pirate
DS1822
SDA
DQ
+5volts
Vdd
Ground
GND
The DS1822 connections are shown in the table. We used the Bus Pirate’s 5volt supply to power the DS1822, but it also works at 3.3volts. A resistor (R1, ~5K) holds the bus high.
All 1-Wire commands start with a reset procedure, followed by one of five ROM commands.
Command
Description
0x33
READ ROM. Read single device address.
0x55
MATCH ROM. Match device address, followed by 64bit address.
0xCC
SKIP ROM. Address all devices together.
0xEC
ALARM SEARCH. Search for alarm condition.
0xF0
SEARCH ROM. Part of address enumeration procedure.
ROM commands are described on page 10 of the datasheet. All ROM commands are available as macros in the Bus Pirate 1-Wire library, see (0) for a menu. ROM command macros
include the 1-Wire bus reset procedure
.
Single device
All 1-Wire devices have a unique 64bit (8 byte) address, and some 1-Wire devices are used exclusively to give electronics a unique tracking number. When a single device is connected to a 1-Wire bus, the READ ROM command will extract its address.
1-WIRE>{ 0x33 r:8
<–command
xxx 1WIRE BUS RESET OK
xxx 1WIRE WRITE: 0x33
<–READ ROM
xxx 1WIRE BULK READ, 0x08 BYTES:
0x22 0x47 0x45 0x22 0x00 0x00 0x00 0x29
<–ID#
1-WIRE>
The command sends a bus reset ({), the READ ROM command (0x33), and reads the 64bit address (r:8, 8 bytes *8bits/byte=64bits).
The first byte (0x22) identifies this as a DS1822 thermometer. The next 6 bytes are unique to this device, and the final byte is a
CRC
of the previous 7 bytes.
Now we can address the device with the MATCH ROM command and send it further instructions.
1-WIRE>{ 0x55 0x22 0x47 0x45 0x22 0x00 0x00 0x00 0x29 0x44
xxx 1WIRE BUS RESET OK

xxx 1WIRE WRITE: 0x00
xxx 1WIRE WRITE: 0x00
xxx 1WIRE WRITE: 0x29
xxx 1WIRE WRITE: 0x44
<–start conversion
1-WIRE>
First, we send the MATCH ROM command (0x55) and the device address (8 bytes). Next is the CONVERT T command (0x44, datasheet page 11) that starts the temperature conversion.
A second command sequence retrieves the temperature reading from the DS1822.
1-WIRE>{ 0x55 0x22 0x47 0x45 0x22 0x00 0x00 0x00 0x29 0xbe r:9
xxx 1WIRE BUS RESET OK
xxx 1WIRE WRITE: 0x55
xxx 1WIRE WRITE: 0x22
…long 1-Wire address…
xxx 1WIRE WRITE: 0x29
xxx 1WIRE WRITE: 0xBE
<–read scratchpad command
xxx 1WIRE BULK READ, 0x09 BYTES:
0x71 0x01 0xFF 0x00 0x7F 0xFF 0x0F 0x10 0xF8
1-WIRE>
The READ SCRATCHPAD command (0xBE, datasheet page 11) returns 9 bytes. We only care about the first two bytes, the rest can be decoded according the the table on page 7 of the datasheet. Temperature is calculated according to page 4 of the datasheet: 0x0171 HEX=369 DEC, 369*0.0625=23C (74F).
Multiple devices
When multiple 1-Wire devices share a bus it’s more difficult to determine all the addresses. The fastest way to find attached devices is with the SEARCH ROM command (0xF0) and a binary branching procedure. The Bus Pirate automates this with macro (240).
1-WIRE>(240)
<–macro 240
xxx 1WIRE ROM COMMAND: SEARCH (0xF0)
Found devices at:
Macro 1-WIRE address

*DS1822 Econ Dig Therm
Found 0x03 devices.
The first 10 device IDs are available by MACRO, see (0).
1-WIRE>
The SEARCH ROM command shows the devices it found, and the type according to the family code.
We think typing 8 byte 1-Wire addresses is really tedious, so the first 10 device addresses are stored in memory and can be accessed with the macros (1)…(10). A buffer for up to 50 device addresses can be defined in the 1-Wire library at compile time. Ideally, this data will be stored in a global scratch buffer shared by all modules in a future firmware update.

The macro menu (0) will also include the device addresses stored in the roster. Now we can just address devices by macro, rather than typing the whole 64bit address every time.

<–start conversion

0x81 0x01 0x4B 0x46 0x7F 0xFF 0x0F 0x10 0x71
1-WIRE>
(85) is a shortcut for a bus reset and MATCH ROM command. (1) is the device address macro, and 0x44 is the command to begin a temperature conversion. Retrieving the reading involves the same macros, but substitutes the command to read the device (0xBE) and grabs 9 bytes (r:9). The temperature is 0x0181, or 24C next to the PC fan.
Taking it further
We used the Bus Pirate to give a visual demonstration of the 1-Wire protocol, but the real challenge is integrating it into your own design. Maxim provides
example code
, Microchip has an
app note
(PDF), and you can check out the
example code
we used.

In manufacturing engineering, which I’ve many years experience with, several methods come to mind immediately and the problem is more of which to select for efficiency rather than if it can be done well enough to bother, even with a PIC. As for my single prototype two separate programs were created. One obtains the romid that is then hardcoded into the other program by hand. Debugging additonal code for discovery of just 16 devices would not have been efficient. There is enough space for it though. Oh yes.. I’m running the network in parasitic power mode, hence the need for the 1500 ohms. Powered would do fine with the 4700 ohm.",

Got 30 minutes for a holiday project and don’t want to get wrangled into some sort of decoupage disaster? Evil Mad Scientist Laboratories can show you just how easy it is to do
edge lighting effects
. Pictured above are three holiday cards constructed using scored plastic. You can use many different types of clear plastic for this, not just acrylic. The lighting is just an LED on a coincell. Black tape is used to prevent light leaking from the edges. The red and green version above is two stacked layers. This looks like something fun to scale up for a larger project or just to kill some time.

[Ewout] sent us some info on this
Automated Gigapixel Panorama Acquisition system
. The system automates the process of taking the large amounts of images required to do gigapixel panoramics. You tell it key information, like what lens, and what percent overlap you want and the system will calculate how many images it will take, as well as the gigapixel count. The results are quite stunning, no visible seams with fantastic detail. Interestingly, this was created for a class in embedded system design (ECE4180) at Georgia Institute of Technology and so was our post earlier today on
Digitally Assisted Billiards
. Is Hack a Day part of the class curriculum? It should be.

That isn’t necessary for rows looking close to straight up or straight down.Next step for my camera is to make it a digital slit scan… I’m not quite sure how to deal with all of the data that I would generate.

[Justin] sent in his
Digitally Assisted Billiards project
. Using a
web cam
, a
computer
and a projector, these guys have set up a system that shows you the trajectories of your current shot. It detects the angle of the cue and displays a glowing blue line showing where each ball would go and where the collisions would be. It is a bit slow right now, and made somewhat less accurate by a low resolution web camera. This could be a fantastic teaching tool if it were to get some more polish. The source code is available on the site, so you could try this one out at home.

Because yes that is why you can’t predict english on the ball. Maybe with a dotted ball and a really good algorithm for spotting revolutions. I can see a laser pointer cue also being used to assist in showing the exact location where the strike will land.With a high speed camera you could technically predict velocity by gaining the size of the pool stick and tracking it’s motion across a known length of the table frame by frame before impact. Of course you are introducing massive framerates into the equations then and slowing the entire thing down even more unless you sample every few frames or so.",

How hard you hit the ball (which you can’t predict) partially determines how much follow it picks up. And topspin changes the behavior of any impact that the ball has, *including* the impact angle.So even a straight shot won’t be simple. I still think the best way would be to have a “weak, medium, and strong” predictions colored with, say, green, yellow, red. Then you have to take into account spin and friction, and you’d be able to make a decent guess.I doubt the problem with the accuracy is the webcam – if you look at the video, you’ll note that the most accurate ones are the shallow-angle shots, which are the ones which depend least on spin.",

Sometimes describing how a lock actually works can be the hardest part of teaching someone about lockpicking. [Mike Gee] has
designed an acrylic lock
that may just be the ticket for these situations. All of the pieces are cut from clear acrylic. As you insert the key, you can see it raise the four pins up to the shear line. He says that it will definitely take some tweaking as you assemble it to get it to function smoothly. Embedded below is a video of the lock in use. You can find
plans on Thingiverse
.

If you leave for the night and your door is locked by a cheap lock, returning in the morning to see it still locked is not a guarantee that someone wasn’t there anyway.Surreptitious (also sometimes called “non destructive”) entry is a whole different category of security risk that some people seek to avoid.Using a heavy lock on a properly-installed solid-core door means that if someone wants to get in to your property (regardless of whether they’re a thief or an agent of the state attempting to search your home) they will have to BREAK in… shattering a window, etc.If you return home after a night away you may indeed find that someone has been there in your absence… but you will KNOW for sure that this is the case and then have the immediate opportunity to take whatever steps are then appropriate.",

I would have to disgree with the guy who said he could fix his kicked in door in 20 min., even the basic US suburb door that can be easily kicked open is not cheap to repair. Even if you do it yourself and use cheap components its NOT a 20 minute process. My house is probably lacking in the security department mainly because I have old windows that would easily be compromised. Someone tried to break into my house before I lived there and the broken door was still in the garage. 1930’s hardwood frame decorative door with a window. The door’s wood cracked at the deadbolt and the door split in half. I’m not sure if this was the owner’s doing or if someone actually tried to break in but at least I know my door frames are good becasue there was no sign of any damage there.As someone who knows lock-picking in an amateur sence I would say if you want to get a new basic lock for your house and are limited in budget to what you can afford from the home depot or whatever take a look at the keys that come with the locks and find the one with the largest end profile and smallest center, this wont stop someone from kicking down the door but will give any inexperienced lock picker a hard time. Also consider installing a steel kickplate around the lock on cheap lightweight doors, this will diperse a kick through a larger portion of the door than just the 1/4″ of wood beside the deadbolt.If someone wants to get in they will, not much you can do about it, but a security system will either make them leave before they steal stuff or possibly get the police there before they do leave. We have had a couple people caught breaking into where I work. The security system makes no noise it just calls the police, the intruders were quite surprised.",

This is an interesting twist on multi touch input. [s9lucas] is using a simple multitouch system as
an instrument that uses solenoids and pinballs to make music
. He has taken the
basic multitouch tutorial
and combined it with an
Arduino bell tower
. The end result is possibly more fun to watch than it is to listen to, but that’s fine.

[Frits] sent us the
SwiitBoard
, an improvised version of the
Wii balance board
. He wanted to be able to do something a little higher impact than he could on the Wii balance board, and required more space to do it in too. Using two different kinds of foam and a piece of plywood, he put together the SwiitBoard. We’re not completely clear on how he is handling direction control. He states that it is derived from gforce.x. Can anyone clarify? Stay tuned after the break for a video of his demo software.

[sixerdoodle] sent us this nice
firefly project that serves as an intro to charlieplexing
. We’ve mentioned
charlieplexing
before, in our
LED Life
post and the
Breath Controlled LED candles
post. This project is quite simple and focues mainly on how to make a charlieplexed circuit work.
The goal was to create a tiny firefly bottle with SMD LEDs and as few wires as possible. In the video, after the break, it is hard to tell just how small this thing is until we see the battery. There are clear directions and fantastic pictures detailing exactly how to set up a charlieplexed circuit with 6 LEDs.

Great job [sixerdoodle], thanks for sending it in.

Firefox Addon Makes Pirating Music Easier

The Amazon MP3 Store may have the lowest prices on DRM free music, but for some people 79 cents for a song is just too much, especially when [john] and the folks at pirates-of-the-amazon.com can help you get that song for free.
Pirates of the Amazon
is a slick Firefox addon that inserts a “download 4 free” button next to the “add to cart” button in the Amazon MP3 Store. After clicking on the button, the addon refers users to a
thepiratebay.org
search page with bittorrent download links for the song or album. While there is no question that this makes getting your music easier, by using this addon you do run the risk of violating copyright laws, depending on which country you live in.
There isn’t much here that hasn’t been thrown into
Greasemonkey
scripts in the past and we wonder if they’re marketing this to anyone at all. People who absolutely love using Amazon but hate buying stuff perhaps? They cite a couple interesting projects in their about section:
Amazon Noir
robotically abused the “Search Inside” feature to reconstruct entire books.
OU Library
searches your local library to see if it has the Amazon book you’re looking for.

A month ago, we reported that Nintendo’s new
DSi
portable
didn’t work with any of the current crop
of flash cartridges. Things didn’t look good for homebrew. Here we are a month later and looking at the release of the
Acekard 2i
. It’s the first DSi compatible flash cartridge. The features appear to be identical to previous versions and we expect other manufactures will be updating their product lines in short order. You can find a video of the Acekard 2i after the break.
These carts may exist because of pirates, but we happily use them for homebrew. There are a lot of great programs out there; here’s a list of
24 apps that are dedicated to music creation
. You can
run Linux on it
too. It’s as easy as copying a file to a flash drive. If you have a
DS
and aren’t using homebrew, you’re wasting it. We’ll be picking up a DSi as soon as they’re in the US (they’re region locked).

And yes Nintendo might release an update that will block the Acekard…which the posibillities are extremely high by the way, but that wont happen unless you stupidly connect your DSi to the internet, come on people really, why use the DSi internet when you have a perfectly good computer that can do that? don’t be lazy wow….and on a side note, Acekard team is not retarded, they monitor Nintendo’s DSi updates so if Acekard gets blocked the Acekard Team will start working on a way to bypass the new security or firmware with their own firmware so eat them apples, not that I will ever update my DSi’s firmware but you get the point, the firmware that my DSi came with since the unboxing is the firmware I’m gonna stick with, besides I don’t do multiplayer with my DSi I have a Super PC for that…and I certainly will not buy anything in the DSi shop because for me that would be called, “wasted money.” And considering….I don’t have WiFi so I can’t even enter into its internet lol, I do go to Starbucks alot but I have no worries because I turned WiFi off on my DSi so yeah…I feel like a winner, thank you….please submit what you guys thought of my rant…laters",

The
Evolution Control Committee
has been doing live mashup performances for many years and recently upgraded their hardware. Inspired by [Johnny Lee]’s
Wiimote whiteboard
, they built a rear projection display they could use during performances. It displays a dense collection of samples in
Ableton Live
. On each of the performer’s hands is an IR LED mounted to a thimble. By touching the thumb to the forefinger, the LED turns on. Two Wiimotes watch for these IR flashes to trigger mouse clicks. [TradeMark G] found the Ableton display too complex to navigate quickly and accurately with a mouse; this new display make things much easier and enjoyable.

The
Ripsaw MS1
is an unmanned ground vehicle built by two brothers in Maine. The tracked vehicle can go 0-60 in 3.5 seconds with an 80mph top speed. In its current form, it has a 2000 pound capacity, which opens the possibility for many different types of weapon systems. Control is provided by two people: one driver and one gunner. They work in independent remote stations. The Ripsaw could potentially be used in any application normally reserved for a tank. It could lead a charge without putting soldiers at risk.
We’ve been watching this project mature since 2005 when it was being marketed as a
Grand Challenge
competitor. This week it’s being demoed at the Army Science Conference. Check out footage of it in motion below.

When you’re prototyping a new project, sometimes all you need is a switch. The folks at oomlout were tired of constantly having to rewire things, so they built a
universal switch box for the Arduino
. It has five potentiometers plus three switches. They’ve put together a software package that monitors the switches and can show you a live view of the knob positions. Have a look at the video below for a demo.
The writeup actually hints at what we can only assume is the next kit they’re releasing:
a robot arm
.

The GO Sequencer

[
"Go",
"maxmsp",
"sequencer"
] |
[Guy John] sent in this
cool sequencer project
. He’s using the game
Go
as the input. A web camera pics up the location of the pieces on the grid and plots them in his sequencing software. You can see that it is still very much in progress, but it is coming along nicely. He openly admits that it may never be completely practical. There is still so much to be improved to get it even comfortably usable, such as motion detection to remove his hand from the mix when re locating the Go pieces. This project is very similar to the
Skittles interface
that we posted back in July. It would be kind of interesting, though probably repetitive, to actually play a game of go and listen to the variations in the music while you play.

Winboni, A Window Cleaning Robot

The
Winboni
is the first place winner in the International Student Design Competition of the American Society of Mechanical Engineers. Winboni is a small robot that cleans windows. That alone doesn’t set the robot apart. The fact that it is held on by suction is what distinguishes it. Running off AA batteries, this robot clings to the window as it cleans it with felt pads. It is hard to believe that this isn’t already a commercial product. Actually, we thought
we had even seen
it before, but we can’t find it now.

Python 3000
has
officially been released
. The final bug,
Issue2306
, “Update What’s new in 3.0” has been closed. Python 3000, py3k, Python 3.0, is a major release for the community. [
Jeremy Hylton
] pegs the
earliest mention
of the beast to January 2000. The new release has grown from
PEP 3000
, opened April 2006.
Py3k breaks backwards compatibility with previous releases in order to reduce feature duplication and promote one obvious way of getting things done. The first major change is that
print
is now a builtin function and not a statement.
int
and
long
have been unified, and integer division now returns a float. Py3k uses concepts of “text” and “data” instead of “Unicode strings” and “8-bit strings”. You can read about many of the changes in
What’s New In Python 3.0
. Some new features have been backported to Python 2.6 so you can start implementing them in your current code to ease the transition. 2.6 also has the
-3
command line switch to warn you about features that are being removed or changed. Finally, the tool 2to3 is a source-to-source translator that should automate a lot of the changes.
Documentation for the new release
is online.
Source packages
and binaries are available now.

Of course, Microsoft is compelled to keep it compatible to some extent so that we don’t cry and swtich to Linux or Mac – enough of our programs break for a new version of Windows as it is!Python can break compatibility between releases because it is MORE AWESOME than Windows (and not an operating system)2) I’m glad that it’s finally here!! Not that I write python (debug/hack/monkey patch maybe, actually write no) but it’s always seemed like a step forward and it’s great that they completed it!",

Like everybody, we sometimes get a little frustrated with our cellphones. Probably one of the most annoying things is when we drop our phones once and they stop working. At Nokia’s hardware damage labs in San Diego, they physically test their phones for extreme uses. They test things like flip tension, water resistance, and even UV resistance. Recently, the folks over at MobileCrunch were given a tour of these labs and were nice enough to post
an in-depth article
about what they saw. In addition to the impact testing video above, there are many more videos posted that demonstrate the tests they perform.

"content": "I live in New Zealand. In 2006 I purchased a Nokia 6234 from Vodafone. This cost me six or seven hundred. It plays movies and music. It can record videos of any length, and can format and use MicroSD. It has bluetooth, infra red, a shiny metallic case, a pop port, a very big screen…. Yes, I can play full length movies on it if I put them on a memory card.I noticed a small defect in the phone and I called Vodafone to report it. It wasn’t major, just a tiny annoyance which I didn’t really want fixed.. I just wanted to place some feedback. The voicemail icon was just aboutr always on, it wasn’t updating properly. Also, if I tried to play an entire movie in full-screen mode it would crash and reset the phone. So, I had to keep track of my voicemail manually, and wait 500 or 1000 milliseconds to go to full screen after starting a video (no, pause doesn’t help).These faults would catch me every time and make me swear, but maybe not worth getting the phone repaired over. Regardless, the charming individual on the other end of the phone insisted that I send it back for warranty repair. I said “OK, sure”. He told me to take it to a Vodafone store. I pointed out that there were no Vodafone stores within 3 hours of here (so total six hours of driving to get my phone fixed…. This could quickly approach the cost of a new phone). Disbelieving, he had to look it up. “OHHHH” he says, and sends me a courier bag to ship away the phone.Amazingly, the address on the bag doesn’t say who I’m actually sending the phone to.So, I wind up with a loan phone. It has no bluetooth, doesn’t take memory cards, doesn’t hnave a colour screen, and is inferior in every way to my real phone. I mean this thing must cost a hundred bucks or so, a real low budget phone.A couple of months later, my phone comes back to me. I’m overjoyed, it’s been so long!It won’t turn on.If it switches on, it takes half an hour to start and drains the battery in ninety minutes. Completely useless, it’s bricked.I send it back, they decide the phone can’t be started and replace it. Eventually they get around to sending me a faulty replacement phone.Anyway a few iterations of this, a year goes by and I have a cellphone which can make videos but can’t take photos. This is what the repair shop sent me.The repair shop is called MOBILE FONE REPAIRS and obviously is useless ;-)… My advice to anyone buying cellphones in New Zealand is IMPORT THEM. It’s cheaper. Don’t worry about the warranty, it’s a waste of money because they will always send you back a broken phone under warranty. Every single time.If you send your phone back under warranty, be prepared to lose it. Don’t make my mistkae, don’t believe in a mobile phone warranty, it’s a myth.",

Since we last reported about
The Great Internet Migratory Box of Electronic Junk
, several of these boxes have begun circulating in different areas of the world. Team Hack-a-Day
launched three
themselves.
Robots.net
decided that there was a need for a specialized box just for those who hack robots, and have launched their own.
The box contains lots of things that will appeal to roboticists, such as servos, various sized motors, RC car parts, and even a small microcontroller board. Plus hackable items like old CD drives, a trackball, and miscellaneous electronic and hardware parts. Everything fits in a standard sized shipping box, but it is
full
. A
complete list
can be found on the robots.net site, and they also have
pictures
of the contents.
Those who wish to track the box can follow it under the name
robots.net-box1
on the TGIMBOEJ
wiki
. There is also a place to get your name added to the list of potential recipients. The wiki contains information about the whole process, including how to start a new box.

Sound Activated Christmas Lights

"christmas lights",
"sound activated"
] |
Christmas is coming up pretty quickly. [tinkernut] shows us how to do a
quick and dirty music activated Christmas light
setup. Simply crack open a pair of old computer speakers and wire the speaker leads to a relay. Use that to power an outlet and you have music controlled lights. The section at the beginning of the video is a bit misleading as that kind of choreography would be rather difficult with this setup. This may look familiar as
we mentioned an almost identical project back in 2006
.

Stop Wasting Your Air Freshener
|

"classic hacks",

"air freshener",
"airwick"
] |
Airwick air fresheners come with an amazing feature. They spray air freshener every once in a while no matter what. It is extremely wasteful and obviously a marketing plan to force you to buy more. There is a solution though. You can
hack them, to turn them back in to a manual release
like they used to be. Two cuts and two soldered wires is all that is necessary.
yes, we know you could just buy an aerosol, but many of us just come home and find them in our bathrooms since someone else in the house bought it. If you’ve already got it, why not hack it? This is also a great project for teaching beginners how to improve hardware.
[thanks Asmor]

(I have yet to test anything besides the 36 minutes setting, and faster is too much IMHO) Using a simple voltage divider across one of the batteries makes this mod simple and easy, hardest part is mounting the sensor somewhere that makes sense.

Simply tag something with a laser and
El-E will go get it for you
. We know this is for the disabled, but we can’t help but think of how nice it would be to have around the house. The system is programmed to recognize the illumination from a green laser and is constructed to be able to reach things from the floor as well as tables and shelves. I wonder if they have programmed El-E to go get the laser for you if you leave it somewhere, kind of like when you leave the TV remote across the room.

Turn Your Car Into A Hybrid

Thanks to a Danish Engineer, you can
turn pretty much any car into a hybrid
. The addition is made in the form of a bolt on motor. As you can see in the picture, there is a motor that attaches to the rear wheels adding an additional 7 Hp. The batteries are stored in the trunk. Kits start at $3,500 and go up to $4,500 depending on battery selection. At least, that’s what they will be when they finally go on sale.

"content": "RE: no free lunch. You guys are thinking of old generators that put out more volts at higher engine RPM. Alternators these days do not require more engine power to run more electronics. The engine does not have to work hard to turn the alternator. One can put too much of a load on the alternator to the detriment of the vehicle battery and the charging system. If the electrical load from these wheel-engines is within the specs of the alternator then there will NOT be any extra load on the engine. If the load and the car’s OEM electrics are more than the alternator is rated for the engine will still NOT be working any harder. It will just run down your battery and/or burn out your alternator because it cannot keep up with the load. If the alternator is rated for 12-14 volts, it will output that amount regardless of 800 rpm or 600 rpm.",

The motors are NOT powered by the alternator – they are powered by the battery pack. According to the site itself – it is not possible to power the system with the alternator.No internal combustion engine will ever have its efficiency raised by running a motor off the existing electrical system. The increased load of the electric motor WILL cause the rotational resistance of the alternator to rise – requiring more power from the combustion engine to accomplish this. Because of the inefficiencies of converting between different kinds of power – it will actually be less efficient than straight up combustion.While I don’t doubt this will raise the fuel economy of whatever it operates on, wether it is enough to justify 8 large will have to be seen. I’m guessing not but we shall see when some results come in.",

"content": "If some of you had bothered to read the information on the site, you’d know that it is not a “free energy” solution. It uses batteries, plugs in and provides regenerative braking. Here is a quote from their FAQ:“Many people are asking ‘Why not charge the batteries from the alternator while on the road?’ Since your vehicle’s alternator is powered by an ICE (gas engine), this would defeat the purpose of a hybrid system.”Think of the system as a power assist on a bicycle – you don’t rely on it to get you all the way to your destination, it merely helps you through the tough parts by supplying some torque so you can conserve your strength.For those of you that are irritated that the electricity is merely “polluting elsewhere” consider this: most of the energy that comes from your gasoline is actually going out of the tail pipe of the car. Cars do not burn all of the gasoline put into them and a hell of a lot of energy is lost to waste heat. Less than 1% of the energy used by a vehicle’s engine is used to move the driver.In a coal burning plant they strive for efficiency – it makes them more money for less fuel. They ensure that most of what goes in is burned. This means you are polluting less, saving money on a gas bill, and reducing our dependance on foreign oil.The only thing that I might take issue with is the price – it should not be that hard to figure out how long it will take for the device to pay for itself…. once there’s empirical evidence from customers, that is.",

If you slam the brakes you get nothing (it doesn’t interfere with the primary function of braking).To store this power you’ll now need some big heavy batteries.“Lets consider your basic 8 horse power engine. With it, you can push around 3 or 4 hundred pounds, but not really all the quickly. With this system, you’re going to add at least that much weight to the vehicle.”This is nonsense. The reason we put cars on wheels is because it offsets some of the force normally required to move something that’s very heavy – the force is transferred to friction on the wheels. It’s much easier to drive wheels than to exert a linear force directly – otherwise we’d have no need for shopping carts, everyone could easily carry all of the groceries around.The counter to this would be if one lived in a very hilly area, though regenerative braking used correctly should still improve efficiency.Nobody is suggesting a violation of the laws of thermodynamics – just a more efficient use of the energy that is already there. If roughly 80% of the energy from the burning of gasoline is being lost to heat that means there is tons of room for improvement. Work is being done to improve how much gasoline is actually burned in the piston and thermoelectric recovery is being tested on the tailpipe. I saw both on Wired, I think, but cannot find it now.Oh, and the motors are installed on both of the rear wheels pictured.",

Half the price and potentially fits a lot of models? Bring it on.And for those griping about the cost, think about this. Most folks building DIY pure-electric vehicles are doing DC-based systems with lead-acid batteries, and getting 40 miles total range, but no regeneration. AC systems give you regeneration, but are $20-$30K. To me, $5K to turn my paid-for PT Cruiser into anything resembling a plug-in hybrid is a bargain. Mark me up as an “early adopter”.

Embedded above is a review/demo of [Ben Heck]’s
Access Controller
. The controller is designed for one handed use and has reconfigurable/hackable modules. The reviewer is [BawNeY] a one-handed Major League Gamer. When using a standard controller, he cradles it on his lap, steering with one hand, and hitting the trigger with his elbow. The new controller looks a lot easier to use.

Ponoko is an on-demand manufacturing service. You submit your design and they’ll cut it out of one of their many
materials
. The site is built so you can sell your products or designs directly. They recently took a major step with the
introduction of Designmake Prime
. It’s a monthly subscription based service with
many benefits
. It lets you submit DXFs for evaluation instead of their standard EPS or SVG. You can request any material you want and they’ll provide direct support. You also get priority in manufacturing queues. While they’ve always offered an à la carte service, this new move puts Ponoko directly in the role of a traditional manufacturer. Offering manufacturing as a service shows their intention of former a relationship with their customers, but at the an individual level, which most manufacturers can’t approach because of scale.
Ponoko first came to our attention when RepRap published an
acrylic version of their machine
.

We were surprised last month when we saw augmented reality being
done completely in flash
. It hasn’t taken too long to go mainstream though. MINI has incorporated it into a recent German language magazine ad campaign. The
fiduciary marks
actually work quite well with MINI’s established ad format. Visit the ad’s URL and
hold the magazine up to the webcam
and a 3D model of the MINI Cabrio will appear. They have a
PDF of the ad
that you can print and use if you don’t have the original. Unfortunately, it doesn’t seem to have cross-platform support.

Cordless Drill Overhaul
|
Caleb Kraft

[
"classic hacks",

"cordless",
"drill"

[Alexander.m] shows us how to do a
major overhaul on a cordless drill
, replacing pretty much everything but the case. He needed some more power, but found the price tag of the bigger drills to be prohibitive. He opted for a more hacked together approach and used a 24 volt 1.4 hp hobby motor as a drive. He had to make a custom enclosure for the batteries too. The final result may not be the prettiest thing in the world, with that giant battery pack on the bottom, but it probably gets the job done pretty well and cost less than half of what a new one would have.

This is about learning engineering with a hands-on approach and getting exactly what you want at the price you want to pay.Face the fact that the exact features or format you need is probably not available (if you are as picky as me), and modifying is probably the best option.All this guy needs to do is move up to Li-Ion power (I suggest using commercially available battery packs though) and use epoxy and fiberglass for the external mod, then it will look great and weigh less. (I am not saying the bearings and gears will last, but for $30 you can get spares from a new drill when they do go.)This seems relevant:http://video.google.com/videoplay?docid=2294060756803022552Maybe Hackaday could contact Tim Hunkin and get an interview?

[Sprite_tm] sent us his latest project. He has found a way to
display custom messages on a laserjet printer without a computer
. He’s using an ATTiny2313 to send signals through a parallel port. This project is so cheap and quick to install it could be disposable. Just program your message before hand, pop it on and walk away.

Disposable cameras are quite cheap, and include circuitry that produces very high voltages. Because of this, they have been harvested for many projects. We’ve seen them used for
coil guns
and large
high voltage power supplies
, even for
fixing rechargeable batteries that won’t charge
. The latest in the long list of uses is to create
nixie tube drivers
. [the_don125] shows us how to use a single disposable camera to power 2 to 3 medium sized Nixie tubes. Be careful, as we said before, this project deals with high voltage.

It should be straightforward to look at the Nixie specs or just measure the current draw and put a resistor in to drop the voltage to 150V, and the flash stepup is designed to be shorted across a huge electrolytic capacitor so it won’t have any problem with a Nixie’s modest draw.",

[Corey Menscher] built the
Kickbee
while attending ITP this Fall. It monitors his pregnant wife’s belly and
updates Twitter
, a microblogging service, every time the baby kicks. The device makes everyone aware of the baby’s movement, not just the expectant mother. It can also log the baby’s activity to monitor development. The sensors are piezos held in place with an elastic band. They’re connected to an
Arduino Mini
which connects to a host computer using a
BlueSMIRF
bluetooth module. The host Mac does the logging and twittering.
This is one of the many projects on display at the
ITP Winter Show
.

The
Dallas Personal Robotics Group
held their semi-annual Roborama contest on Saturday November 22nd in Garland, TX. The DPRG had a table at the recent
Austin Makers Faire
. Each spring and fall, they hold the Roborama contests for autonomous robots. The spring event has contests for outdoor self-navigating robots. The 2008b contests were designed to test the abilities of indoor robots. Normally held at the Science Place, this year they elected to have the contests at the DPRG warehouse in Garland.
There were a wide variety of robots represented: lots of built-from-scratch projects, some lego-bots, and a few off-the-shelf models. Computing power ranged from nothing up to an on-board PC with WiFi. The
Polulu 3pi
‘s were heavily represented. The builders themselves were anything from high school students to veteran club members.
Winners had their choice of prizes in order of placement in each contest (first place got to pick first, etc). Prizes included a
STM32circle
, a pair of servos, or gift certificates to a local
electronics store
. Other entrants got a mini-cylon LED display to make their robot a little more menacing. You can view full
results here
.
The simplest event was the Quick-trip contest. This competition had the robots move from the starting area straight to a second area, and back again. The area is enclosed by walls and marked off with black tape, and the robot must completely cross the tape to be considered in an area. While it sounds very simple, not all robots were able to complete the course. The winners were determined by who successfully finished the course in the least time. This years winner of the Quick-trip contest was a lego-bot named Gort built by student Nathan Harlan.
The second event is a little more complex, called T-Time. This one has three areas, and tests the accuracy of turning. There are 3 areas, the robot starts in one, must visit the other two and return to the start area. The course is a ‘T’ shape, so the robot must make a couple of turns. It was won by David Martineau with BoxyRoxy Mk IV.
The third event was a line-following competition. Robots must follow a white stripe on black background, with lots of sharp curves. The course itself was only about a yard square, so smaller bots fit more easily. This year the line following was all about the Polulu 3pi’s. At least 4 entered, and all of them used the unmodified hardware: the only difference was the programming. One contestant used a genetic algorithm to evolve a neural-net. Another contestant programmed his on the day of the contest. The winner was PI R Squared, owned by Steve Rainwater.
The next Roborama will be sometime in the spring of 2009. DPRG holds montly club meetings. They also have the Robot Builders Night Out, which is a chance for roboticists to meet at the Garland warehouse and work on thier robots. It is open to anyone, not just club members.

Upgrade An Electric Lock Keypad

[OldGrover] bought a Weiser electronic lock. Only 6 months after installing it, the keypad stopped working. Instead of just accepting this, [OldGrover]
built a better button pad for his lock
. He decided to go with big push buttons instead of a similar to stock membrane system. After tracing out where the original buttons connected, he attached his new buttons and enclosure. Pretty simple really but it fixed the problem and kept the lock out of the landfill. Now, he has a unique looking keypad on his front door.

[Ben Heck] posted his
PS360 controller
. This is the case of an Xbox360 controller with the guts of the Dual Shock 3 from the PS3. They Dpad is from a ps2. We guess that if you can build them any way you want, you might as well make it exactly how you want it. Wasn’t there a time when
everyone laughed
at the bulky Xbox controllers? Yes, we know, they’re smaller now but that comic pops into mind anyway.

[aris] is continuing work on his
harmonic table keyboard midi controller
. Instead of the traditional linear keyboard layout, keys are laid out in a hexagonal pattern. This is the same idea as the C-Thru AXiS, which you can find a
video demo of here
. Along the left edge is a row of buttons to transpose the layout up or down. Switches for octave up and down along with a generic slider are also included. The final controller will include a 16×2 LCD character display. The core of the controller is
MIDIBox
, and he’s using the SDK to write the custom C code. Embedded below is the first test with just four buttons wired.

Here are a couple small programs to help you make the most of your Playstation 3 Sixaxis controllers. [netkas] heard that quite a few people were having trouble using the Sixaxis controller in Windows Vista. He solved it for himself and
uploaded an exe for you
to use. He then did essentially the
same thing for OSX
. This should make your PC gaming feel at least a little more familiar.

Gameboy Color On An LED Matrix

Here is a video of a
GameBoy Color being played on an LED matrix
. He has built it up to 140×140 LEDs so far and it seems to be going well. He needs to add the final 20 LEDs to get the 160×140 resolution of the GameBoy. He notes in the comments that he had some problems with dead LEDs in the boards he got from eBay. Trying to remove the dead LED with a hot air rework station resulted in massive damage to the board. At one point he says that the power consumption is 1KW when showing all white. Wow, that’s a drain.
[Kevtris] gave us some more info in the comments with a link to the build pictures in
his blog
.

On standard ultra bright red die run at 25mA for 2V, whih is 50mW (for 150mW for white RGB light).Also, the leds are certainly muliplexed. If they are pulse and get 100 time more current during 1/100 of the time, they will look really less bright than if they’d get normal current during the whole time. So I really don’t think that it will blind you.",

[marcan42] wanted to
use a plain old GambeCube controller to play Super Smash Brothers Brawl
and some other titles. Apparently you can just use a WaveBird wireless controller but according to [marcan42] they are
hard to find
. You may recall a similar project for building a
wireless Snes controller
for your Wii.

Real Life Gears Of War Lancer For Zombie Fighting

[SOC] posted this crazy
real life Lancer
, like those found in
Gears of War
, on the AR15.com forums. You are seeing it right, that is a chainsaw bayonet attached to his assault rifle. We thought
these were pretty cool
, but this thing actually works. It can be seen on an AR15, pictured above, as well as a giant shotgun. We think the shotgun one would be better fitting for zombie hordes. Barney Fife seems strangely fitting for this picture. Check out a video of it in action after the break.

That’s not the most graceful or efficient method of opening a door, but it gets the job done.

Great call on that weight info BTW, it looked so light in the pictures.Too bad he won’t be able to sell this to DARPA or anything now.

In [
Bre Pettis
]’s latest “things” video, he talks with [Adam Mayer] about his
geared business cards
. [Adam] has designed several versions of these cards that have functional gear systems in them. There appears to be a simple two gear one and a more complicated planetary gear set up. The designs have been uploaded to
Thingiverse
, so you can download and build your own.

Bus Pirate Firmware Update (v.0c), JTAG And More

A few weeks ago we wrote about our
Bus Pirate universal serial interface tool
. We used the recent holiday to add some new features, like a JTAG programmer, macros, frequency measurement, and more. A major code reorganization makes everything easier to read and update.
Check out the a demonstration of the new features below. We’re compiling a roadmap and wish list, so share your ideas in the comments. You can also see how we used the Bus Pirate to
read a smart card
and
test-drive an I2C crystal oscillator
.
New protocols
I2C>m
<–setup mode
1. HiZ
<– high impedance pins (safe mode)
2. 1-WIRE
<– not ready for this release
3. UART
4. I2C
5. SPI
6. JTAG
<– interface and programmer
7. RAW2WIRE
8. RAW3WIRE
MODE>1
900 MODE SET
HiZ>
This firmware release lists three new protocols.
Hi-Z makes all pins
high impedance
/input, a safe state that won’t damage an attached circuit. To be safe, the Bus Pirate now starts in this mode.
1-Wire is listed, but we couldn’t include it in this release because we still don’t have any parts to test with our library. This is just a placeholder for now, but it will be added as soon as we get a 1-Wire part to test.
We wrote a simplified JTAG interface that includes a XSVF player for programming JTAG device chains.
**We included a hardware I2C library, but according to the device errata
there’s a bug in the 24FJ64GA002 rev3 I2C module
. This will work with a different chip (e.g. a 28pin dsPIC33).

JTAG
JTAG
is a debugging and programming interface for all kinds of electronics. The raw hardware interface can be accessed with the Bus Pirate’s raw 3 wire library, but we added a few features to make it much easier.
JTAG has different modes where data entry does different things. Modes are navigated with the JTAG TMS signal; there are a
bunch of JTAG modes
, called states.The Bus Pirate’s JTAG library is just the raw 3 wire library, enhanced to help with JTAG state changes.
We only implemented the JTAG states we need to get data in and out of a JTAG device chain: reset, idle, data register, and instruction register. Macro (1) issues a JTAG chain reset, and initializes the chain to the idle state. { puts the JTAG chain in data register mode. [ puts the chain in instruction register mode. ] or } return the chain to the idle state. The Bus Pirate has an internal state machine tracker that is smart enough to manage the chain without explicitly returning the chain to idle; in other words, you don’t have to close your tags. The state machine tracker reports every state change to help debug problems.
JTAG>[0xfe {rrrr}
<– same as [0xfe]{rrrr}
xxx JTAGSM: ALREADY IDLE
xxx JTAGSM: IDLE->Instruction Register (DELAYED ONE BIT FOR TMS)
610 JTAG READY TO WRITE IR
<– JTAG chain instruction register
620 JTAG WRITE: 0xFE
<– request ID
xxx JTAGSM: (WROTE DELAYED BIT) IR->IDLE
<–back to IDLE
xxx JTAGSM: IDLE->Data Register

630 JTAG READ: 0x60
630 JTAG READ: 0x59
xxx JTAGSM: DR->IDLE
<–back to idle
640 JTAG IDLE
JTAG>
Here is a short interaction with a
Xilinx XC9572 CPLD
. We go to the instruction register ( [ ), and send the device ID request command (0xfe). Then, we go the the data register( { ), read four bytes (rrrr, or r:4 shorthand), and return to idle ( } ).
What are delayed bit writes?
JTAG requires that the last data bit written to the instruction register be entered at the same time as the state change. Since the Bus Pirate has no way of predicting when we’ll actually change states, it delays the last bit of each byte write until one of three things happens:
Exit the instruction register with a }, ], or { command
Write another byte value
A read command
Pending bits are not cleared by bitwise operations (like ! or ^). Do these before writing your last byte, or change the code. We haven’t implemented pending writes to the data register, but it’s probably needed. You might need to implement this if you’re writing the data register, rather just reading, like we did.

JTAG>
Macro 3 is an XSVF player/programmer using code from Xilinx. XSVF is byte format
SVF
,
as described by Xilinx
(pdf). XSVF files can be compiled for any chain with the correct
generic JTAG definition files
, even non-Xilinx devices. We successfully used the
binary
transfer features in
Hercules
and
Tera Term
to send XSVF files to the programmer.
JTAG sometimes pauses longer than it takes the PC to transfer a byte of data, so we implemented
XON/XOFF software flow control
for the XSVF player. Your terminal must be in XON/XOFF flow control mode before you upload the XSVF file, or the programmer will fail. Even with software flow control, a modern PC has already send several bytes through the layers of operating system before it receives the flow control signals. We deal with this by catching these bytes before moving on, this is reported as the maximum number of bytes “dribbled”.
If there’s an error in the upload, the PC will probably continue to spit bytes at the Bus Pirate. To keep error messages visible, and prevent garbage in the terminal, the XSVF player waits for five lower case z’s before it returns to the prompt. We chose this sequence because it will never occur in an XSVF file.
*Note that the XSVF player does not respect the JTAG Hi-Z pin setting. Went it does, it fails. Be careful mixing voltages without a buffer.
Better code structure
The biggest difference between the version 0b and 0c firmware is a massive improvement in code structure. The Bus Pirate existed in many incarnations before we packaged it for the initial article. v.0c harmonizes the code libraries and makes it easier to add new protocols.
How to add a custom protocol
The Bus Pirate code handles the user interface, and passes two variables to the active protocol library. The first variable is a command, such as CMD_READ, CMD_READBULK, or CMD_WRITE. The entire command set is defined in base.h. The second variable is an optional value. A simple CMD_READ command passes no value, a bulk read command passes the number of bytes to read, a write command passes the value to write to the bus, etc. At minimum, a custom protocol needs a function to receive these variables and translate them to bus actions.
We used three different techniques to link commands to bus actions. Simple code can go directly in a giant switch statement, like SPI.c. External libraries use an single linking function, like I2C.c, and m_i2c_1.c. More complicated protocols use the switch statement to call functions included in the library (raw2wire.c, raw3wire.c, jtag.c UART.c). Helpful functions for terminal IO are included in base.h/c.
Due to massive code improvements, it’s now only mildly confusing to register a new protocol with the Bus Pirate:
base.h
– Create a definition for the protocol. The last entry is currently “#define RAW3WIRE 7”, so the next entry could be “#define MYCUSTOMWIRE 8”.
busPirate.c
– Include a header file with that gives access to the processing function. Add a menu entry in the
char* mode[] =
variable list. The menu entry
must
be in the same position on the list as the number assigned in the base.h define. If MYCUSTOMWIRE is number 8, it must be the eight entry in the mode variable. Finally, add an additional switch to the bpProcess() function that calls the custom library processing routine when the mode is set to “MYCUSTOMWIRE”.
Taking it further: a Hack a Day wish list
We compiled the feedback we’ve gotten into three wish lists: protocols, features, and macros.
Protocols
1-Wire
, with enumeration (*ready as soon as we have parts to test it)
OBD-II
(thanks [
Shadyman
])
CAN
MIDI
(
Wikipedia
)
DMX512-A
IRDA
,
RC5x
, etc.
Some protocols will require an external transceiver.
Features
Pulse-width modulator, frequency generator
“Wait until interrupt” command
Convert frequency measurement to input capture peripheral
Allow frequency measurement on any pin
Show a report of the current configuration settings and pin states.
Integer repeat values for bulk read, clock ticks, delays, etc.
A CRC generator
Macros
Transparent UART bridge
SD card initialization, meta data extract, and dump
EEPROM program/dump (I2C/SPI)
Nokia 6100 LCD initialization, control
NMEA GPS data decoder
Do you have anything to add to the list?

[Matthew] sent us this
Nintendo 64 stuffed into an NES
. He did a great job really, everything looks nice and tidy. the presentation is decent with only the game ports visible on the front to tell you its not stock. The accent lighting on the side vents is not overpowering. Overall this was a really well done mod. Just like the
Nintendo 64 in a Wii
mod, this only plays Nintendo 64 games. OK guys, lets get some mods going that don’t involve cramming one
Nintendo
product into another Nintendo product.

Using VFDs As Amplifiers

"vacuum fluorescent display",
"vfd"
] |
[HP Friedrichs] sent us this cool writeup on how to use scrapped
Vacuum Fluorescent Display tubes as amplifiers
. For those unfamiliar, a VFD is a display device common to electronics. Many have been replaced by LCD, but you can still find them in modern products. [Friedrichs] points out that his 2008 ford has a VFD for the multimedia display.
Since these units are basically tubes, he figured that you should be able to use them as a tube amp. After some testing, he found it to be quite adequate. The project includes tons of background information on how tubes work, how VFDs work and how to utilize it for amplification. In the picture above, you can see him using one (middle) to amplify a home made radio (right).

Gadget blogs have been a fluster the last day about
TechCrunch
stating that netbooks “
just aren’t good enough
“. Writing a response post hasn’t proven very hard given the number of factual errors in the original.
Boing Boing Gadgets
points out that the low-end of the spectrum that TC post seems to cover are almost impossible to purchase because they’re so outdated.
Liliputing
rightly states that comparing the browsing experience to the
iPhone
isn’t worthwhile since it’s entirely a software problem.
Laptop
goes so far as to recommend the
HP Mini 1000
and
Samsung NC10
specifically for their keyboard. TechCrunch isn’t alone in their opinion; this week Intel stated that using the ultra portable devices was “
fine for an hour
“. TechCrunch is designing a web tablet right now using the
collective wisdom of blog commenters
. Looks like they’re just reboxing a netbook
for the prototype
.
We cover the netbook market for different reasons than most: Their low low price makes people much more willing to hack on the device. For the price of a smartphone, you’re getting a fully capable
laptop
. The low performance doesn’t matter as much since we’re running
different flavors of Linux
that are much lighter than Windows. People
running OSX86
are doing it to address a market that Apple doesn’t.
What’s your experience with netbooks? Do you have one that you adore or are you annoyed by their shortcomings? Models we’ve covered in the past include the
Acer Aspire One
,
Asus Eee PC
,
Dell Mini 9
, and
MSI Wind
.

However, I miss having a very portable PC for some mid-level gaming (Quake 3, Starcraft, Worms, etc) since I have neither my Eee or my HP, so I am looking at the Asus n10j or possibly an n20 (if you can call it a netbook). I also considered putting one on my car with an external laptop hard drive and using Winamp for easy-to-use car audio selection, but I never followed through with the project.

I wouldn’t be too bullish about predicting future sales (re: all previous bubbles that have burst in the last 8 years) but the existing sales figures don’t lie. There might be a debate about how big netbooks will get, but they’ve already gone from nonexistent to selling quite well. The question isn’t whether they’re popular – the question is how big they’ll get. Techcrunch seems to think we’re just waiting for a slightly larger iTouch to spring from Job’s noble brow, so we can ditch all our wee little keyboards, but the fun of netbooks is as eliot said above – they’re cheap enough to hack, and since you’re hopefully running linux, you’re going to learn a few new things along the way if you’ve never run it before. If you’re not in it for the tinkering, you have a 2-3 pound computer. Win-win.And the keyboards aren’t much better than a Blackberry’s? What does TechCrunch wake up and smoke? Focus on a device that only runs a browser? I’m sorry, but the most fun I have with my EEE is either messing around with the OS or with the programs I can put on it, now that I have Ubuntu eee installed. I’m in school for computer science with an interest in network security, so I’ve been messing around on my home network with software like Wireshark and the Aircrack suite. My eee is great for this, and as my first Linux box (got a 701 4G about 10 months ago) it’s been very good practice getting familiar with Unix.And right now I’ve got the eee hooked up to a giant keyboard, mouse, and a 19 inch Dell monitor. Not a bad faux desktop, really. I can’t run any games, but for most of my needs, it works just fine.At least the big TC linked to someone critical of them. Too bad they don’t have a link here for the amalgamation, or to BoingBoing for the sass.",

"content": "I had to give up reading at “You have to use the keyboard or trackpad to scroll down, and it means taking your eyes off the screen,” as I can’t laugh without waking someone. The idiocy of not being able to find the trackpad or the arrow keys without looking is just too humorous. A very hit-seeking troll post.I’ve had two ultra-portables (not netbooks as the price when new was well over $1000) a Libretto 100CT and P1120, which were both under powered for 2007 (when I got them cheaply used). Both had there uses.I got the Asus EEE PC 701 shortly after it came out, as I had killed the P1120 at that point. The small res and size of the screen was the main issue I had, particularly going from a 8.9″ 1024×600 screen on the P1120. Still decently OK at surfing the net at lunch. I sold it to my roommate during finals last year, as he was borrowing it so much anyway.Next I got the EEE PC 900, going back to 8.9″ 1024×600 was a huge help with webbrowsing. I’ve actually used the 900 and P1120 as my primary machine for a week or more using the in-built display, but had to seek out an external display to use with the 701 to use it for more than a couple of hours. The extra storage is nice too.(For pics of all four, click my name)Right now, I’m waiting for Netbooks based around the GMA 500 –more-capable, less power-hungry– Atom chipset, before considering getting a replacement for my 900. If I was looking to buy now, the Dell Mini 9 looks awesome (passive cooled is a huge boon for in-bed or other non-flat surface use).",

"content": "TLDR version: I am sick of these slow little plastic excuses for innovation and the mundane “hacks” that anyone armed with a soldering iron and the schematic of a mag-lite can pull off.Let me preface this post with my personal position on the subject of hardware hacking. I have endless interest in and respect for the pioneers who look at things from the outside and evoke true ingenuity. Multi-touch table folks, Jail breakers, Benders, Phreaks in the day and people who push the security envelope, rock on. What I’m about to post isn’t an affront to the foundation of the hack scene or hackaday at all.I feel that the original post has too much implied consensus. The real questions that land on the desks of the computer manufacturers are not about how a nano-faction of consumers like to void warranties and solder run of the mill usb devices onto motherboards.The original poster refers to the Netbooks as “fully capable laptops”. Fully capable of what exactly? I wouldn’t even enjoy using one to blog about the mods I did to one. Most of them are so anemic in the media abilities that they can’t even playback video proper at the native res of the panel. That in my book = horse shit.No matter how light a distro of Linux can be installed on these things, you will never find one with negative weight.Netbooks are marketed to people who don’t need even marginal computing. If you own a single other computer and use it at all for what you do, than you really are outside of the scope. Not that they mind the sale of course. If you don’t own another computer besides your netbook, I feel for ya @_@If the modifications were really what sold these things, not just why certain prolific internet show and tellers want them, the design and marketing would be more accommodating of such modification.And that’s the crux of the issue. For example, when small solid state storage became mainstream, the manufacturers noticed the demand and designed the Netbooks to contain one or several readers onboard. I am seriously not impressed when someone pops a different flash ssd into a mini-pcie slot and calls it a hack. For fucks sake, not a hack. Kudos.Hit us up when you ball a better processor and reflow it in a toaster.Bringing OSX86 into the mix is really really reaching also. If the only people working on the osx86 project were netbook owners, it would not exist. Mostly because of the pathetic processors. *cough*Wake us up when something awesome happens.P.S. Where is the hack again?Xoxo",

"content": "I love how lots of kiddies disown the netbooks because they cant play fallout 3 or watch HD video on it. they declare it “useless”.yet I’ve been using netbooks for real business for over a year now. They work great. I recently upgraded all the eee’s here to the Acer aspire one because for the same price we get a giant HDD, faster proc, and they happily go up to 2gig in ram. we do on site programming of crestron and Vantage systems with these and they work GREAT. Hell I run dreamweaver and flash 8 on mine for my playing around. and when I boot out of XP and into linux I can do some serious programming on it wherever I want.Buy just a netbook? that’s silly. Get one to suppliment your laptop. but that netbook is killer for whipping out a patch to an app when you are sitting in the bleachers at half time or in traffic in the carpool. Then as college students discover these they never want to take a full laptop to class again. My wife loves her aspire one running ubuntu. she can do everything in class she needs, she can even use it easily to record the class for later referral and I’m happy because it’s virus and spyware proof.I do agree netbooks like the early eee’s and others that had only flash ram are really only neato hacking toys.. but the current ones with a decent hard drive and atom processor kick it hard. the LED backlight of my aspire one is brighter on it’s lowest setting than most new laptops are on their highest setting.If you are some poor kid that thinks $350.00 is a lot of money, no you will not like a netbook. If you are a professional that likes to get stuff done or a student that needs more desk space.. you’ll love them.",

It’s not a blazing fast machine and media on it is pretty poor but that’s all with the std linpus install. I’m planning to upgrade to Ubuntu and I expect things to be even more functional.I think the reason these get a bad reuptation (if there is indeed one) is because people don’t knwo what they’re buying. They think it’s a cheap little laptop and assume it will be as fast as any other laptop. These things are not fast and are not confortable with windows. Linux is cool but takes some getting used to. Open Office is awesome.I have absolutely no complaints. The only thing that is slow is video and I’m sure that with a RAM upgrade to 1g along with Ubuntu it should be fine.Worth noting, I also have a Samsung Blackjack with internet. My Acer is so much better than the phone in so many ways it’s silly to suggest that anyone would prefer to use the phone IMO.",

This thing should be cheap enough so that I don’t have to be worried about it on the job. Other uses I can think of is a serial terminal for connecting to the console of routers and switches.

Embedded above is [egyokeo]’s solution for using MIDI drums with Guitar Hero. He’s playing a
DrumKAT
MIDI kit. It connects to a PC running his
MIDI Hero
software, which handles timing and multinote combinations. The PC uses a USB
ToolStick
microcontroller to send commands to the console
using an FPS adapter
or soldered into the instrument. It’s a fairly good solution if you’re building a generic controller and need to modify the signaling.
When Rock Band was first released, modders sought to adapt their MIDI drum kits for use with the game. The easiest solution they found was Highly Liquid’s
MSA-P
. It’s a photorelay based MIDI decoder. You need to solder directly to the brain in the Rock Band drums. If you’re planning on modding any instrument, check the
compatibility matrix
first. Hopefully you’ll end up with something that can be used across multiple games.

Nice update on the work, anyways. :PJust a note — it’s my understanding that the drum kit for Guitar Hero WT’s midi port on the back *can* accept an input (I saw it in an interview), as well as be used for an output. I don’t have the hardware to confirm this, but this could be used as a bridge for the drum aspect of the project (the kit works in RB as well, I believe), though it wouldn’t allow drums to play as guitars (as the featured project shows). Just throwing it out there, I haven’t honestly seen much experimentation in the area.–matt",

Embedded above is a demo video of an
iPhone running a Linux 2.6 kernel
. The iphone-dev team has created a new bootloader called OpeniBoot. The bootloader lets you boot into a Linux console, which you can talk to over a USB serial device. They’ve got busybox working, but there is no touchscreen support yet. The instructions are not that difficult and include how to back up your settings. It works on first and second gen iPhones and first gen iPod Touch. This is a very early port, but the future is wide open… Android iPhone?

tbeta
is a new tool developed by the NUI Group Community. tbeta acts as an image processing layer to take in image data and output tracking data for multitouch applications. Whether
FTIR
or
DI
, scratch built multitouch systems generate IR video streams that need to be processed to find fingertips. tbeta can take this or any arbitrary video stream and run it through a series of filters to generate the touch data. This data is sent as OSC
TUIO
, a standard protocol for touch events. Along with the camera and input switcher, tbeta also aids in system calibration. I works on Windows, OSX, and Linux. Have a look at the
getting started guide
for a better idea of how it works.

Also, tbeta is much more efficient then touchlib, so the first poster must have been away from the touchlib scene for a while and not tested this new tbeta software. In tbeta, DSP is around 2-6 which means tracking speed between 166-500fps which is much higher than touchlib. 500ms wasted? Who said tbeta only supports flash? Not to mention, flash supports binary sockets, so this issue is null, if this integrated (which I believe it will be). There’s also many improvements in calibration and filters. If you’re judging latency by the video, it’s clear that tbeta isn’t the culprit of latency, but the webcam must be using lower fps (20-30). Any other tracker, touche, bbTouch, or “homebrew” will have the same results when using a low fps camera. If “zero latency”, which is something that is impossible, is more important than accuracy, then I’m scarred lol. I’d rather my touches touch the right parts of the screen and pick up my blobs than be fast and press wrong things on the screen and not pick up my fingers. Of course there’s flaws, but for a version 1, it’s much less flawed than other trackers I’ve seen.",

[skeezix] has got his hands on one of the
first Pandora dev kits
to make it out the door and took a few photos. This is 1 of the 20 MK2 devboards that were produced. Although, not final it certainly is close to the version they’ll be shipping.
Pandora
is a
Linux
based portable game console. The main chip in the clamshell device is a
TI OMAP3530
. It has OpenGL hardware acceleration and an 800×480 touchscreen. A QWERTY keyboard is included along with analog and digital game controls.
WiFi
,
bluetooth
, USB host, TV-out, and dual SDHC card slots round out the package. The team has already presold 4000 devices.

The Xbox 360 has a brand new motherboard. Dubbed the Jasper, it presumably has a new 65nm process GPU. The new box has a 150W power supply instead of the former’s 175W brick. They’ve changed the plug design to prevent usage with old consoles. The most notable change is the onboard flash memory upgrade. Earlier consoles only had 16MB; new ones have 256MB. The majority of this storage will be used for the new dashboard, the
NXE
. The remaining space can be used for game saves. With the new storage, Arcade units are no longer including memory cards. You can see more images of the boards on
Xbox-Scene
.

[mixadj] needed to run some video cable from one part of his house to another. He was lacking the proper amount of video cable, but had a bunch of cat5 laying around. so he built a converter to run his
composite signal through the cat5
. He states that he wouldn’t run it more than 70 feet without amplifying the audio somehow. Aside from that, the performance is supposedly decent. This just adds to the multitude of other uses for that Ethernet cable. We’ve seen voice, data, composite video,
VGA
, and power. What else have you seen run over cat5?

You can get converters (as opposed to adapters, which are passive) to send almost anything over UTP (CAT5, 6, whatever): video of almost any flavour (HDMI, VGA, composite, component, DVI); KVM controls; CCTV (as mentioned before, using active baluns); and all manner of other control signals. Without any circuitry, you can send VGA, USB, telephone (PSTN), audio, power, composite video, PS2 (keyboard/mouse), and the list goes on. I have used CAT5 for doorbells, intercoms, burglar alarms, CCTV systems, telephones (digital and analogue), HVAC signals, thermostats, paging systems, distributed audio, home automation- I could probably go on forever! I’ve used it for every level of voltage and frequency it’s rated for in my jurisdiction, and probably some it’s not!Seriously, though, the only thing I don’t think I have run over CAT5 is my car. Christopher gets modded +5 for Awesome.PS: Only somewhat related, but you can run USB over PS2 extender cables. I have successfully run keyboards and mice over a single 50-foot PS2 extension cable with PS2-USB adapters on each end. Total cost is something like $8, and there’s no electronics involved. Get a keyboard with a USB hub in it- that helps! You can’t run a webcam (too much power loss), but I have put powered hubs at the end and used it that way.",

No matter what holiday you choose to acknowledge, you probably enjoy the thought of getting to put lights up everywhere. We know we do. Here are some instructions on how to
