[Epoch] Sent in this
simple head tracking project using Lego pieces
. He’s made a custom mount to hold 3 Lego light sensors on a baseball cap. Then, after modifying his webcam for IR with some floppy disk scraps, he loads up the
free-track
software and can control his games. For convenience, he has programmed the Lego Nxt to only turn on the lights while he’s holding a contact sensor. You can see it in action after the break. This appears to be very similar to
[Johnny Lee’s] head tracking
. Judging by the video, it’s not as smooth though.

With some careful programming and probably tedious testing, [Tim] was able to get his
CNC router to play [Jonathan Coulton’s] “Still Alive”
. He didn’t just tell the motors to spin at the correct speeds directly though. He computed the 3d vectors necessary to produce the notes. The router thinks it is just doing its job. We would love to see those vectors rendered out in 3d space. Imagine having a physical sculpture of “Still Alive” as seen by a CNC machine. This reminds us of the
Obsolete Technology Band
.

RF Modem + 250mW Amplifier

] |
[Trax] sent in his writeup on this
RF modem with built in 250mW amplifier
. The original power of the RF transceiver was around 10mW, his final results after testing were nearly 250mW. He was able to to easily transmit data over 1000 meters using his test setup. He states that he was actually able to achieve this without an antenna on the receiving side. That’s pretty impressive performance. It’s also worth noting that he soldered all of the components in place using a home clothing iron and some soldering paste. That must have been fairly tedious.

I haven’t looked at it yet, but I’m fairly certain that implementation he uses does not employ frequency hopping (though the CC1100 is definitely capable of it)",

Almost exactly a year ago, we posted the
random USB capslocker
. [Garrett] has revisited the idea to build a smaller, neater version. He has
posted the build process
to give us an idea how he goes about building things. The overall build is quite nice, but part if its neatness can be attributed to the fact that he had access to an Epilog laser cutter. If you think you might be using one in the near future, this is a great writeup for you.

[Killerdark] has built a
simple remote for his toddler to control videos
on a PC. He gutted a USB number pad, built a new enclosure with the necessary buttons clearly labeled, and mapped the buttons in software. He could have possibly done better with larger color coded buttons, but really, it seems to work well as is. This reminds us of the
giant iPod remote
from back in 2006. Good job [Killerdark]

[Eschlaep] put together this
beautiful kitchen timer
using a
dekatron
.
We
see
all
kinds
of
tube
projects
, but dekatron projects are fairly rare. The over all aesthetic is quite nice, though we’d be tempted to find a way to protect that high voltage circuit.

If you feel the same way that we do about robotics, you probably wish that you had more experience with them when you were a kid. [Don] felt that way too, and he decided to do something about it. So [Don] and his partner started the Chicago based organization
Bots 4 Tots
, with the mission of introducing inner city kids to robotics. [Don] told us that his organization plans on starting the kids with snap together projects like OWI’s
Jungle Robot
. After a few snap together projects, they plan to introduce the kids to soldering and hope to eventually move on to a larger collaborative project that all the kids can work on. Of course, doing all of these things requires money. Thats where we, as the DIY community, come in. So feel free to hit up the Bots 4 Tots site and
make a donation
to support their worthwhile cause, we know we will.

Simple, Elegant, Lemon Battery

Caleb Kraft

[
"LED Hacks"

[
"epilog",
"flower",
"led",
"lemon juice",
"light"
] |
[Madaeon] pointed us toward
this entry
for the
Instructables Epilog challenge
. While this may not be extremely complex, or have as many wires as our typical post, it is a fantastic example of thinking outside the box. How many lemon batteries have we seen? A lot. This one stands out as being more elegantly displayed and functional at the same time. In its final form, you sprinkle lemon juice on it’s petals and it lights up. If you ever find yourself in the position of teaching someone about electronics, remember this project. Sometimes aesthetics can make a dull simple project take on a life of its own.

Speech Controlled Garbage Can

[
"pic",
"Speech controlled garbage can",
"voice control"
] |
[youtube=http://www.youtube.com/watch?v=–BIlxKVCYk]
This
speech controlled garbage can
was sent in via the
tip line
by [Amnon]. The garbage can will come to you following a black line and stopping when it sees a cross in the line, then waits for another voice command. It can then return to where it belongs or go outside following the line. The system is based on a microchip PIC 18F4431 and uses three 18 volts cordless drill motors and their batteries as the power source. “In the near future the line sensors will be replaced with UV line sensors and the black line will be replaced with clear UV color.”
When you call the system “Pach Zevel ” (garbage can in Hebrew) the system go to standby and the LED’s light up. After the previous stage if you say “ELAY” (to me in Hebrew) it will drive on the black line till the first crossing.
This adds new meaning to taking the trash out.

S-video From An Atari 2600

[Ben Heck] posted this writeup about
getting S-Video/composite out of an Atari 2600
. This is actually the hack of [Longhorn Engineer], who showed it to [Ben] at a recent event. If any of you have tried to play these classics on a modern TV you may have found it to be quite difficult. If you manage to get it physically connected, through adapters and such, you may still have video issues. This alleviates that issue completely. After you solder this in, your Atari has native composite/S-video. As you can see in the video after the break, it seems to work pretty well.

I’m from Argentina and i’ve learned english without a teacher, just by my self, so i’m not the best spelling :PI didn’t wanted to criticize your work, just saying that is possible by other ways to get something like that, with some less quality.@jeremiah:I didn’t remember very well how the nes worked, but i do remember that i’ve made an stereo sound mod to the famicom (nes clone). If it had Y/V/C lines it might be possible i think…",

The
Phoenix
is a very impressive hexapod robot platform. It has 18 servos which gives each leg 3 degrees of freedom and a BasicAtom Pro 28 for the brains. Interestingly, the design started as a personal project of a forum member on the Lynxmotion forums. It turned out so well, it has become an actual product. We’ve seen videos of these before and they always have some pretty fluid and organic seeming motion. They seem almost alive in this configuration. The only thing that might make them scarier would be to add
Lou Vega’s decapitated head
, well maybe that plus some
really nice face tracking
. In the video above, you can see where someone
paired one up with a Wiimote
for a pretty intuitive control scheme. Yeah, we realize the video is nearly a year old, how did we miss this one? You can see a video of it walking around after the break, and another controlled by a ps2 controller.

The following one seems a bit quicker on it’s feet.

[Eddie], who made the
Mac Logo LCD Mod
, had posted a
step by step tutorial on how to do it yourself
. He basically just fully disassembled his MacBook, popped out the logo, put one from an iBook or Powerbook, then mounted a small LCD back there and routed it into a USB port internally. He says the extra electronics cause a tiny bulge in the monitor casing. We wonder if this couldn’t lead to stress damage on the main LCD in the long run.

[Tempt One] is a graffiti artist who has Lou Gehrig’s disease. He can no longer physically produce art, since his disease has taken his ability to control his arms. His friends, won’t let that be the end of it though. They’re
building a visual tracking system
to let him
work by moving his eye
. It seems like it would be very difficult to get any kind of a smooth curve out of eye movement, but the short demonstration video, which you can see after the break, does a decent job, at least for something this early in development. The source code isn’t released yet, but they do plan to do so. If you wanted to make your own, you could
find some info in a past post of ours
. We’re guessing they intend to use it with something along the lines of the
laser tagging system
.

This would allow your friend to literally look at where they want the effect to happen (through the prism) rather then estimating by using the other eye. You might have problems with resolving the eye or light levels though I guess. Just a thoughtI meants one of these:http://en.wikipedia.org/wiki/Beam_splitter",

Perhaps a momentary switch to the LED as well, hold in only when using the capability?Last, my idea uses eye tracking to control servos- how could this be implemented? Do you need a laptop to make use of this, or could a program running from something like a gumstick computer do the trick?Finally- idea- why not, instead of using IR, put on a custom contact lens with a calibration ring on it in bright white- have the camera lock on and calibrate to that, or a grid pattern. That way, no IR needed! Could that work?Excuse me if the questions are stupid- I can make anything, but programing is beyond me so far.",

However, IR can still damage our eyes. An important question would be, how much can we reduce the power but still be able to pick up the signal using cheap hardware (e.g., webcams).Your idea about only flashing the LED occasionally is a good one. IIRC, LEDs have 2-4ms response times. It should be possible to use pulse-width modulation to reduce power output but still have a signal that is visible to a webcam operating at 30hz.Eye tracking could probably be accomplished using embedded hardware (like a gumstix computer) that could then interface a server.But one issue that hasn’t really been mentioned much is calibration. I’m pretty sure that you would need to do some calibration each time you moved your head relative to the IR emitter and webcam (i.e., every time you adjusted the glasses or put the glasses on). To do that, you would probably need to have the user look at points on a fixed surface.Another issue I just thought of is that the shape of the eye effects the relationship between how it moves and what it’s focused on.Would colored or shiny contact lenses help out? Sure but contact lenses can move around on the eye, they don’t always stay fixed.",

You can also dim LEDs using a constant current power source (and lowering thew output to dim it), and LED driver chips usually work off that principle.Also a general note to people: Cheap webcams work great for seeing IR but you need to disassemble them and remove the little glass filter over the lens. They will usually see some IR without doing that but its *much* much better if you remove the filter.I’ve used a cheap microsoft camera i got at frys for $20 and it works great without the filter.Also remember that the eye is exposed to loads of IR light from the sun normally, though the pupils dilate in that situation so this may be worse, not sure.-Taylor",

In the case of the gentleman here, my idea to use a momentary to control the IR could be with a simple mouth switch- a pressure pad he can bite down on since his arms no longer work. With an underclocked IR LED, this would also save his eyes from unnecessary damage.@ werd- thanks for that link. It’s nice to see it’s been done, but that setup seems far too complex for what I need. My main concern is how the servos would actually be linked with openeyes software- as far as I understood, the original stuff that came up didn’t support servo controls in any way. I’m trying to figure out how the eyetracking software could be linked to a servo control interface- my guess is it’s a software issue beyond me. I need to make friends with some CMU students near me, maybe someone there could help. Software & even simple arduino programing is something beyond me!@ Andrew- yes, I see now the contact lens grid idea wouldn’t work, since the shape of the eye and movement of the lens would negate calibration.Final question I’ll throw out- can a laser point directed by a pointer be homed in by another laser mounted to a servo? ie: I point with a laser pointer, and a servo mounted laser with a camera facing out (a reverse eye tracker?) centers it’s laser on that laser point? I’m designing something for targeting an airsoft gun.Maybe I’m nuts? I’ve seen programs that track the brightest point on a screen, and thought it could be narrowed to only track a green laser point.",

Dear Hack a Day,
Websites keep publishing poorly executed jokes today; how can I fix this?
We’ve been getting a lot of questions on the
tip line
like the one above, so we put together this one-step illustrated how-to. If you’re not the physical labor type, you can use [Steve Lambert]’s
SelfControl
.

The massive hacker camp
Hacking at Random 2009
has
extended their early bird ticket sales until April 14th
. At EUR150, they’ve already managed to sell 1000 tickets. Every two years the european hacker community gathers together to hold a multiday camp that covers topics from hacking to art and politics. 2007’s
CCCamp
was largely the inspiration for this year’s
ToorCamp
. HAR2009 is looking for people to submit presentations, workshops, and lectures as well. They’re looking for entries that are very technology focused. The call for papers deadline is May 1st. The team is hosting a field day April 18th to tour the grounds with the various hacker villages that will be setting up. The main even is August 13-16 near Vierhouten, Netherlands.

We touched on harmonic table MIDI controllers when [aris]
was building one
. [Ken Rushton] has one of C-Thru’s commercial keypads, the
AXiS-49
, and
disassembled the device to show how it works
. A
PIC18F2450
microcontroller provides the USB interface and is connected to a
dsPIC33FJ128GP310
digital signal controller which decodes the keypresses. The membrane buttons are made with two concentric graphite disks that touch gold contacts. The microcontroller measures the time between the two points contacting to determine the button velocity.
monome button clones
also use circular contact pads, but cannot calculate velocity because they only have one element.

The Dream Tablet

[Matthew] has completed this
Dreamcast tablet modification
. That’s right, you’re looking at a Dreamcast laid out in tablet format. We’re not really sure what advantages the tablet layout has, since it’s not touch screen and you probably need to put it down to play anyway. The
laptop
or clam shell might have been a smart choice simply for screen protection. Putting that aside, this is really cool. He had to do some extensive re working of the motherboard in the Dreamcast to get it to fit. Interestingly, he hacked together a custom disk drive for it too. You can see detailed pictures of the entire process, including the construction of the case, on his site. Great job [Matthew].

Through-hole Bus Pirate Kit From Fundamental Logic

Fundamental Logic is selling a
Bus Pirate kit
and
bare PCB
based on our universal serial interface tool. They started with our serial port-based
v1a hardware
, and modified it to use all through-hole parts. 8pin DIP
LP2951ACN
/
-3.3
switchable voltage regulators replace the surface mount
TPS79650
/
33
that we used. The PIC is pre-programmed with our latest
firmware
, version 0f, which includes a bootloader for easy firmware updates through the serial port. Documentation includes illustrated
assembly instructions
.
Speaking of Bus Pirate goodness, we’re busy working on
hardware V2
. As astute readers may have
already noticed
, the final version of the Bus Pirate incorporates an FTDI USB->serial chip, and draws its power from the USB port. We also tackled the software-controlled pull-up resistor feature, and reduced the overall part count and cost. Best of all, we’re working to make assembled PCBs available with world-wide shipping. The how-to should be ready in a few weeks.

The Narcisystem is part of an art display where
[Eric] strapped himself to as many biometric sensors as he could
. The core of the system was a
Funnel IO
which includes an Arduino, Xbee plug, and LiPo charging circuit. It was collecting data from a heart rate monitor, an EEG, a
breathalyzer
, compass, and an accelerometer. This data was sent to a
laptop
and then sent to different displays. You can see the setup functioning in a video after the break. The red flashes are his heart beat, the blue light is the direction he’s facing. What you can’t see is the high power bass thud every time he takes a step. The EEG data was supposed to effect the tempo of the music, but it failed and was dropped, as was the fog machine based on his blood alcohol level. He notes that he
wanted to do more, but was lacking the hardware

Macro Photography With CHDK
|

[
"classic hacks",

[
"chdk",
"macro photography"
] |
[Tim] photographs insects for bugguide.net. As you can imagine, macro photography is a must. He was very frustrated with his camera’s stock ability to capture the insects. You can see in the example on his site that the image is blurry and has some color issues. He did some research and
hacked together a method of getting fantastic macro images for relatively cheap
. He used the
reversed lens method
to get his macro lens set up. He then modded his camera with
CHDK
for more control. He found that his focal distance was too small to get the entire bug in focus, so he took 15 images at different distances and combined them to make the final image. We’re curious how the
pringles can macro lens
would compare to this. Thanks for the submission [sp’ange]. Lets see some more
tips

I played around with reversing the lenses on my 35mm camera 30 years ago, back when I could barely afford film and paper, and “discovered” it was a good way to get macro shots, (my 55mm filter thread happened to slip nicely over my Pentax mount.) I’m also sure I didn’t discover it first, and that it’s been going on a lot longer.These days you can purchase pre-made “reverser rings” that specifically provide a threaded mount for your lens, or you can just hold it in place. It’s certainly not a “hack” to reverse a prime focus lens. You just have to be careful to stay within the limits of your setup, and not expect perfection out to the corners of the frame, for example.Anyway, I applaud him for his nice combination of good ideas: low cost equipment, plus software to achieve his goal. I’m going to try using his CHDK script and stack a bunch of frames to see if I can get some decent macro shots, too.",

It is odd that he didn’t pick up a cheap old fast prime with manual aperture; there are no shortage of them on ebay let alone in any local camera shops.I’ll also say his price comparison was a bit disingenuous. I shoot with an old nikon flash and a sigma macro lens (combined price: £75) for outstanding results… mount it on an old DSLR body (cos you need precisely zero bells and whistles) and the final price is waaaay shoty of $2000.

"content": "To those suggesting a DSLR for this, they sure don’t know much about photography and digital cameras. That’s for damn sure. Due to the larger sensor the DOF in all macro images in a DSLR is much much shallower than that in a P&S camera. A P&S camera is the ideal choice for all macro photography due to its inherent deeper DOF. Hand-held macro photography in available light at full aperture is easy with a P&S camera. With a DSLR you require using flash to use the smaller apertures for enough DOF, and have to put your rig on a tripod. Not only is this cumbersome but the flash destroys the quality of the subject. I will use no other type of camera than a smaller sensored P&S for exceptional macro photography these days. Add in the high-speed burst focus-bracketing that CHDK offers, adjustable to any step-size your heart desires, as many frames as you want, at the highest burst rate your camera can shoot, and there’s no better combo of cameras and operating systems on the planet for this task. For those looking for inexpensive adapters to use their old SLR glass, in reverse, as macro lenses on their P&S cameras, just type the words “macro coupling” (without quotes) into the search box at Adorama. They’re only $8, one size costing $14. That minor cost is worth all the trouble of trying to create your own from old filter rings. And for you DSLR-pushing idiots, get a clue and some experience with real cameras before you offer such lame advice again.",

Reader [Joshua] sent in his latest project. using a sonar rangefinder, an Arduino, and some clever programming,
he’s made is computer react to his distance from it
. As you can see in the video after the jump, he has programmed it to change text size and background color depending on his distance from the screen. While he admits that his implementation doesn’t seem immediately useful, there’s lots of potential there. We can actually think of several uses. What would you use it for?

Add one more servo to give you a controlled Y axis to move the beam up and you could do a 3D plot of your envelopment. Kind of spiral scan.

We’ve
posted a plethora
of Guitar Hero style hardware hacks, but this one is completely different than the others. Behold, the
Banjo hero
. This unique controller was constructed from an old banjo and a guitar hero controller. Custom software was then built with custom songs for game play. We really wish we could see it in action. There are a couple videos available for download, but they are just pictures of the build process.

The
Arduino MEGA is official
and even more expansive than we
originally thought
. It has 54 digital i/o pins. 14 of those can be PWM outputs. Along with 16 analog inputs and 4 UARTs. It is even compatable with most shields for the Arduino Duemilanove or Diecimila.

If you have infinite time, sure go buy the parts, it is open source you can do that. If you start to look at the cost difference between the parts and the assembled final product and compare that to the number of hours it would take you to assemble the thing, you’re essentially paying yourself to make the board. Would you guarantee perfect assembly of one of these boards if I gave you $40 and a box of parts?

"content": "@yourmom,Before you start diving into insults here, you might bother to check your own name, first. The people that the arduino is targeted at, has been targeted at, and will continue to be targeted at are not the people who will buy a cpu, place it in a bread board, pull their icsp out and burn some hand coded assembly code into the device, and then design their own circuit to do just what they need. Those people have the hardware already, and have the know-how.Lets compare real prices, shall we? The arduino mega costs 65$ and a quick froogle serach finds a usb jtag programmer alone costs 50$. Now, since we’re talking about introducing a complete non-specialist to programming, they probably won’t have a serial port on their computer, so they’ll need to get one of those. They’ll need a bread board, a small collection of resistors and caps, some crystals, a separate usb/serial chip for the breadboard, a power regulator, a few transistors, and some leds. Now, for the price of the jtag and the cpu alone, they can buy the arduino mega and have the other cash for sensors or the rest of their project.if you were just hating on the arduino, then you need a lesson in trolling. you are factually correct given the audience here at hack-a-day. You are just missing the broader audience in the world outside.",

"content": "@quin: Whoever mentioned JTAG? All the stuff I’ve mentioned has an onboard RS-232 bootloader. Connect a UART to a PC and you’re set. Yes, you supply your own USB->RS-232 if you need it, but it seems silly to have one on every board anyway. What people seem to be missing here is that, on the hardware side, Arduino is just glue. It’s an AVR, regulator, USB->RS-232 chip, a couple passives and some headers. The only real value-add is preloading the AVR with the bootloader. I think what people are objecting to is that a simple CPU swap and adding a few headers more than doubles the price – that’s not in line with the current product.I don’t know who’s talking about complete newbies here, but it isn’t me. I’m overjoyed that Arduino exists to make simple digital control more accessible to more people – exposing artists to completely new forms is fantastic and leads to some really neat stuff. It’s great that something like this exists for schools, and anyone else interested in fooling around with electronics. The barrier to entry is lower, and the learning curve less steep, and any time that happens is a good time – but there is a price. For the target market it’s the right choice and the price isn’t objectionable if it suits their needs – and I’m glad the Arduino team has been so successful – their efforts deserve reward.For those of us that know a little C and understand a bit of the internals (which I would hope is a lot of hAd’s audience) – and are liekly to have at least one RS-232 port on hand – there are other options that are more powerful and more cost effective. They just require a bit more skill to use because nobody’s put the work into making them accessible to the layman. The ARM development tools are quite good, there’s a ton of code out there, and like AVR, there’s a GCC branch. You don’t need a JTAG or ISP just like you don’t need one with Arduino – use the on-chip RS-232 bootloader that pretty much every ARM selling today ships with. You don’t need assembly – use C. Never deal with 8-bit overflow again!But yes, you will need to read some datasheets and understand them to use anything more than basic IO. If you’ve mastered Arduino and want more, maybe look at switching architectures for more powerful tools.@cgmark:STM32F103 does do hardware PWM, it’s just not listed on Futurlec’s featuresheet. Each of the 6 PWM-capable timers can have 4 output compares, so 24 PWM lines are possible. Check out their other stuff though, they have some breadboard-style development boards as well, or head over to Olimex instead (who have a lot more selection). There are some boards that are very Arduino-like with more capable processors, and some other cool more app-specific stuff (relays, LCDs etc.)",

You don’t get a fancy IDE though. You can then set up Eclipse to help you manage your projects, and ST has a free tool for uploading code to the device via the serial port.

[adafruit] wrote in to let us know that the
Tweet-a-Watt is now available in kit form
. While the
plans have been available
for a while, a kit is a welcomed addition. The kit doesn’t include the Kill-a-Watt monitor, but rather the XBee adapters and parts necessary to make it talk to your Arduino or computer. The kit is $90, while the Kill-a-Watt can be found for roughly $20.

Combine that with an X10-like wire transmitter and a $1.50 Atmega and you can have nearly the same functionality for $30 or so (less if you have junk to raid for parts), not $110. Not to mention that you can probably attach multiple ammeters, or just one on your house shunt. (in fact, if you could design one to safely clamp around your bus-bar you would only need one.) You could use a portable device to measure your devices’ draw and then when your usage increments by that amount, the device is active.(somebody please show me a $20 Kill-a-watt, all I can find is ebay [dodgy] and Newegg, $25+ after tax and shipping.)",

Especially given it may not be more than an equivalent clamp-on ammeter. killawatt was $8.50 from the library (they used to rent them out) while a used 75A clamp-on ammeter that wasn’t routinely overwhelmed by RF noise was $17.Granted you can build a functional current-shunt meter or hall-effect meter for less.",

I mean, wow.. you managed to log your desk-lamp power usage to the internet.The real use of these devices is to go around your house with one and collect data on EVERYTHING. Then come back, sit with all of it on paper and figure out where you can cut your bill. (wow, that 40 watt bulb in the halway is really sucking the current down, maby I can change that for a 20?) constantly monitoring only one appliance is sort of like missing the point. Knowing that your washer is a power hog doesn’t change the fact that you still need to wash your clothes.as pointed out by several people, some way to watch your entire house power usage would be nice… ohh.. wait.. the electric company installed one of those fancy meters with the spinning wheel on it right there on the side of your house.So, here is my published hack:parts needed – pencil, paper (ruled), eyeglasses (Depends on your eyesight), house, gumption (that attribute that determines your willingness to get off your ass for 5 minutes a month, rather than relying on a fancy plug in module to wirelessly deliver all its data to your lazyboy while you watch the big game)optional – ruler (to draw straight lines)Step 1 – using pencil (and optional ruler) divide paper into 4 vertical columns. Mark the top of each column with the following headings: date, previous reading, this reading, monthly usageStep 2 – go to your meter on the side of your house. Apply eyeglasses (if necessary). Read meter. Enter this information in the “this reading” column. Also not today’s date in the date column.Step 3 – collect underpants, make profit, wait one month.Step 4 – (30 days later) go to meter. Re-apply eyeglasses (if necessary). Read meter. Note this information in “this reading” column. Also note the date.Step 5 – carry the data from the previous month’s reading in “this reading” down to today’s entry under the “last reading” columnStep 6 0 subtract last reading from this reading. Enter the result under “monthly usage”Hack completeVariation – use PC and spreadsheet software in place of paper. You can also slightly automate the process.Tip: publish your data on twitter to track your progress and allow others to learn how much you depend on the air conditioner.I suppose if you wanted to make one of these devices really useful, wire it into your air conditioner, or behind your fridge, or your washer/dryer combo.at any rate, logging it to a spreadsheet sounds useful. But could the designers spell out for me why the heck you’d want to put it on twitter? I dislike all the twitterhype. Ive never bothered to look at twitter, so I don’t know what all the buzz is about. please… justify the reason for twitter. I just don’t get it.",

The only flaw with the this meter is that its only use-full to monitor a single circuit. It’s more use-full to audit your per-device consumption but to get a better understanding or view of your energy consumption you have to monitor your total consumption. For most people the energy wasted is not caused by a single appliance, though outdated/rusted water heater will add a nice chunck to your monthly bill (as I learned).

[oomlout] has released this
Opensource robotic arm
. It is 5 axis, using cheap hobby servos. The total cost, including
having it cut at thingaiverse.com
is roughly $150. The plans include all the pieces, down to the servo controller. This means that you’ll have to supply your own microcontroller and programming. They do state “We can guarantee it is loads of fun to play with, and we think potentially very useful for more serious pursuits.” and we would like to test that guarantee. We’ve been keeping an eye out for this ever since the
servo switch assemblies
.

I’m going to use it in a light automation role at my company (gphirrigation.com) for an intermediate step in assembly. The problem is, the parts aren’t welded yet.

With
all the noise
about
Conficker
turning your computer into liquid hot magma on April 1st, there’s actually some positive news. Researchers from the
HoneyNet Project
have been following the worm since infections started in late 2008. They recently discovered an easy way to identify infected systems remotely. Conficker attempts to patch the MS08-067 vulnerability during infection. A flaw in the patch causes the machine to respond differently than both an unpatched system and an officially patched system. Using this knowledge, the team developed a proof of concept network scanner in python to find infected machines. You can find it in
[Rich Mogull]’s initial post
. [Dan Kaminisky] has
packaged it as an EXE
and has instructions for how to build the SVN version of
Nmap
, which includes the new signature. Other network scanner vendors are adding the code as well.
In conjunction with this detection code, the team has also released the whitepaper
Know Your Enemy: Containing Conficker
. It discusses ways to detect, contain, and remove Conficker. They’ve combined this with a
tool release
that covers Conficker’s dynamic domain generation among other things.

Even if not userland stuff can still be just as dangerous, 64bit users aren’t protected either, you can get pass driver signing on SP2C x64 XP even from the shell, and you can still DDK a 64bit driver that hooks and moves around low level abstractions from device interrupts up to kernel tables.The perfect malware would be kernel or user mode, either one+ a good threaded mutating packer+ a shellcode dropper using multiple++ vulnerabilities in native services such as tcip.sys server table checks(would allow infection even on dead ports SYN or whatever), and a lot low level file system and kernel table hooking.The fast spreaders all use SMTP or shellcode droppers.

I can alsoadd that most of consumers running Linuxhave higher level of expertise that averagebilly joe running windows. To make this evenless unprofitable, there are not enoughconsumer Linux boxens out there to justifythis claim.So yes, we are perfectly secure running aLinux box. But lets not all remember tostart using Linux at the same time or maybeI’ll have to start closing ports andtaking paranoid precautions on my computersin near future.@cornelius<>Yes, you are right.Although default security provided by mostof GNU/Linux distros is *GOOD*, after youstarting using your brand new system you’llhave to take care of it. It’s not likeinstall and forget.My home server is bruteforced a lot on thesshd service. Sometimes I look at thelogged IPs to see who is it.Most of attackers are proxied by a hackedLinux box. From a few deep investigationsI did, I can tell that breakin the causewas weak root (admin) password.So my point is:It’s *not* just because you are runningLinux that you will be the securityoverlord. You have to secure it with goodpasswords, close any unneeded serviceto the public, be careful on whatinformation you (admin) expose to thepublic, update regularly, inspect log filesoften, use a hardened Linux.A hardened Linux box will certainly comewith most of apps running in a chrootedenvironment (to limit damage in a breakin).They will be running selinux (if properly configured, it will make near impossibleto hack the computer).They will come with very secure configurationdefaults.So yes, given all of that I can for sure say:– GNU/Linux is way more secure than Windows.If you guys don’t believe it, just googlefor selinux and try to explain me whatwould be the equivalent on a windows server.",

Most companies use it on backbones for this reason.”Indeed.I don’t think “linux is for everyone” (TM)either.I love linux because it oversimplifies(as in methodology) software research.I could tell you a lot of jokes aboutcolleagues of mine spending a lot of timedoing things on windows that would be donein a matter of seconds using a few bash lineson linux, like copy pasting unformatted datato excel one-by-one at hand : \\It was nice to talk with you all,thanks for your time.",

Simple shellcode payloads are defeated by it, but allocators have been around since the nineties and continue to be defeated through trampoline techniques and such. there have been a lot of xor allocators defeated through trampolining of native processes and tables both on linux and windows.I guess technically it is protection, but I didn’t give that credit to windows either, windows just has better randomization and obscurity.The software emulation of nx bit on both platforms are also allocators that just flag frames.You might know something I don’t. I don’t monitor the innovations that much. I just know it’s not effecting my work and I have 9x and nt installs over and almost a decade old now. reformatting is like buying a new car when a battery needs replaced.I’ve been a fan of openbsd for a long time and use it exclusively on servers and some laptops. I have about the same level of security on my nt machines as I do my thinkpad with an anally retentive configured openbsd 4.4 install on it.

[Avi] sent in his
PSP as a status monitor hack
(zip). He’s using Lua on the PSP, so you have to install LuaPlayer. The computer side is written in python, so it should be cross platform.
Last time we saw a psp as an extra monitor
, it had more capabilities, but it was limited to Windows. You’ll find the Lua script as well as the python in the zip file. It’s a nice use for an extra psp.

Parts: Programmable Gain Amplifier (MCP6S26)

Microchip’s
MCP6S21/2/6/8
are programmable gain amplifiers that multiply an input voltage by a factor of 1, 2, 4, 5, 8, 10, 16, and 32. The MCP6S22/6/8 also have selectable input channels for working with different signal sources. The multiplication factor and input channel are configured through an
SPI
interface. This chip is useful for multiplying a small input signal, and selecting among several analog input sources. We demonstrate the six channel MCP6S26 below.
MCP6S26
programmable gain amplifier (
Mouser search
,
Octopart search
, $2.56)
Datasheet
(PDF).
We tested the chip in the circuit shown above with a 3.3volt power supply. A resistor voltage divider (R1-4) outputs a fraction of the supply on channels 0, 2, and 4. We used 5K resistors, but the value isn’t critical. The divider outputs 2.4volts on channel 0, 1.6volts on channel 2, and 0.8volts on channel 4.

We used our
Bus Pirate universal serial interface
to demonstrate this chip, but the transaction sequence will be the same for any microcontroller implementation. We connected the Bus Pirate to the MCP6S26 as shown in the table above. We setup the Bus Pirate for raw3wire mode (M, 8) with normal outputs, and enabled the on-board power supply (capital ‘W’).
RAW3WIRE>[0b01000001 0] d
CS ENABLED
<–begin SPI transaction
WRITE: 0x41
<–change input channel command
WRITE: 0x00
<–change to channel 0
CS DISABLED
<–end SPI transaction
VOLTAGE PROBE: 2.4VOLTS
<–Vout voltage measurement
RAW3WIRE>
Writing 0b01000001 (0x41) followed by a channel number changes the active MCP6S26 input. ‘[‘ lowers the chip select line to start an SPI transaction. We send the change channel command (0x41) followed by 0 to select input 0. ‘]’ raises the chip select line to end the SPI transaction. ‘d’ takes a voltage measurement and shows that input 0 with 0 gain is 2.4volts.
We can’t amplify the input voltage beyond the power supply (2.4volts * 2 = 4.8, 4.8volts > 3.3volts), so we need to change to a lower channel to play with the gain features.
RAW3WIRE>[0b01000001 4] d
CS ENABLED
WRITE: 0x41
<–change input channel command
WRITE: 0x04
<–change to channel 4
CS DISABLED
VOLTAGE PROBE: 0.8VOLTS
<–Vout voltage measurement
RAW3WIRE>
A measurement on channel 4 shows an output of just 0.8volts, plenty of room to test the gain features of the chip.
RAW3WIRE>[0b01000000 0b00000001] d
CS ENABLED
WRITE: 0x40
<–change gain command
WRITE: 0x01
<–gain setting (x2)
CS DISABLED
VOLTAGE PROBE: 1.6VOLTS
<–Vout is now 0.8volts * 2
RAW3WIRE>
A two-byte sequence sets the amount of gain. The command 0b01000000 (0x40) addresses the gain register, the second byte sets the multiplication factor (0x01= gain of 2). Setting the gain to 2 multiplies the output voltage by 2, 0.8volts * 2 = 1.6volts.
RAW3WIRE>[0b01000000 0b00000010] d
CS ENABLED
WRITE: 0x40
<–change gain command
WRITE: 0x02
<–gain setting (x4)
CS DISABLED
VOLTAGE PROBE: 3.2VOLTS
<–Vout is now 0.8volts * 4
RAW3WIRE>
This time we set a gain of 4, 0.8volts * 4 = 3.2volts.
RAW3WIRE>[0b01000000 0b00000011] d
CS ENABLED
WRITE: 0x40
<–change gain command
WRITE: 0x03
<–gain setting (x5)
CS DISABLED
VOLTAGE PROBE: 3.3VOLTS
<–not enough headroom to reach 0.8volts * 5
RAW3WIRE>
The maximum output voltage is the chip’s power supply voltage. If we set the gain to 5, the output voltage can’t exceed the power supply of 3.3volts (0.8volts * 5 = 4volts, 4volts > 3.3volts).
RAW3WIRE>[0b00100000 0] d
CS ENABLED
WRITE: 0x20
<–sleep command
WRITE: 0x00
<–don’t care byte
CS DISABLED
VOLTAGE PROBE: 0.0VOLTS
<–output is disabled
RAW3WIRE>
The MCP6S26 has a power-saving sleep mode. Shutdown the chip with the command 0x20, followed by any byte value. Leave sleep by sending any valid command.

You might be better off using a digital potentiometer for volume. This chip could be combined with that though so that you can have the capability of selecting multiple inputs, as well as having the benefits of a preamp.One interesting use for the multiple inputs is that a series of filters can be created and the inputs can be chosen to switch various filters in and out of the circuit.

Arduino + Wii Nunchuck + Servos

[Yezzer] has posted a video of a cool little project he’s working on. He has
interfaced the Arduino and the Wii Nunchuck
to control some servos. He mounted a standard
USB
webcam
on it for good measure. There isn’t a whole lot of information, but he does include a few links to code he modified for the project. The movement is quite natural looking and seems like it would be a cheap way to get some good animatronic controls started. This might actually be a great way to control a robot for the
Crabfu challenge
, if they ever have another one.
Update: As [dokument] points out in the comments below, it looks like we’ve seen a
set up that could be almost identical
in the past.

We’ve been watching and waiting intently as
ToorCamp
comes together. It’s a four day hacker conference that will be held in a Washington state missile silo July 2nd-5th. While we’re excited about this debut event, its success depends entirely on those presenting. The
call for papers
is currently open and they’ve got a number of formats available: 20 and 50 minute talks and 1 and 2 day workshops. They’re also looking for people to
organize campsites
and are offering discounts for groups. We’re encouraging you to submit your talk since we’d love to see more hardware talks. You can follow
@ToorCamp announcements on Twitter

A team of three PhD students constructed this ‘
multi-mallet automatic drumming instrument (Madi)
‘. Their
Expressive Machines Musical Instruments
site is dedicated to building instruments like this and they recently showed their work at the first annual
Guthman Musical Instrument Competition
. A ‘low-stakes X Prize’ for musical instruments. 25 applicants were chosen to show their unique musical instruments for $10K in prizes. We like the team’s Madi because it’s adapting a traditional instrument and then pushing it to the limit. It reminds us of the
Crazy J mechatronic guitar
from 2005. You can see a video of the Madi playing below.

[Jeremy] picked up a Vexplorer pretty cheap, and wanted to make it better. He decided that
Arduino controls would probably be a nice upgrade
. He patched into the controller and installed a nice looking plug to interface with the
Arduino
. He says the software was custom made as he couldn’t find suitable examples on the net. His software is available for download. We covered a
picaxe controlled one
in January, but it looks like that site is currently down.

None of them have a formal education as electrical engineers. (IT, art-school, etc)Really, I’m confused as to why this social process is happening within a community of such creative people.A (supposed) low quality of the posted articles can not be an excuse for the increase in put-down, nay-sayer, initiative-squashing type of comments.If the articles are of mediocre or low quality, why not post a better one instead ? Or, just ignore the article if it’s crappy.So, rather then focussing on the ‘fail’ -as someone put it recently- why not acknowledge the the effort some random person on the internet (and whos background you do not know), and suggest e.g. improvents, or at least learn hownotto do something.Maybe half of the negative comments are ment ironic or otherwise non-literal, but don’t forget that those subleties are mostly lost in printed text and across cultary boundaries.Keep up the good work !",

I modded one of the servos from the original Vex kit so that I had two continuous rotation for the wheels, and one for the shoulder. I used a regular Vex servo for the gripper. After a few hours of playing around with it under remote control, I hooked it all up to an Arduino while more batteries were recharging. Vex servos are just regular servos in a different package, so you don’t have to do anything fancy to make them work with an Arduino.From there pretty much anything is possible.I added sonar and a couple of contact sensors to the base and gripper. I messed around with the IR motion sensor from Radio Shack a little bit. The program would have the robot seek out a corner using sonar, turn around to face into the room, and wait for someone to enter to run at with the gripper flexing. That was pretty fun.The last thing I did with it was to add a cheap airsoft machine gun on top of the shoulder. I interfaced it with the Arduino with a relay wired parallel to the trigger switch. I modded my hide and wait program so that it would find a corner to wait in and come out shooting while weaving back and forth. My wife did not like this. Not at all.Really this is a pretty fun platform to play with.",

could be very useful. Photographing them can be quite difficult at times, they throw off the standard settings on your camera pretty easily. EMSL takes us through all the settings for best results. While you’re brushing up on your photography skills, you might want to consider making a
flash ring
, or
some
kind
of macro lens. Now go take some awesome pictures and
submit your projects

This year’s
Google summer of code
has been kicked off with a fairly substantial amount of participants. You can still submit an application until April 3rd, to join the roughly 2,500 “graduates”. For those who don’t know what it is, the Google summer of code pairs developing programmers with open source projects and funding. It’s a great program, resulting in advances in some programs that we follow. We’ve talked about several of the groups that will be participating this year, such as
the NUI group
, rockbox, openstreetmap, and
videoLan
.

We’re putting a bounty on two high-priority
Bus Pirate
features. You can get a free PCB for the upcoming Bus Pirate V2 by writing a bit of code. Hack a Day has a varied and talented group of readers, and we know someone out there has the experience to make these changes with minimal difficulty.
The latest code integrates the PIC24F bootloader for easy updates without a programmer. We’d like to add a protocol snooper, but that requires interrupts. With the bootloader, however, interrupts are relocated and we’ve yet to fully grasp how that works. We’ll send a PCB and PIC 24F to the first person who modifies the code to demonstrate UART, SPI, or change notification interrupts with the boot loader. Microchip’s 24F bootloader app note is available
here
.
Complete
.
The current frequency measurement feature is a hack that uses a counter and a timer. Be the first to implement the input capture peripheral instead, and get a free PCB. See the function
bpFreq(void)
in
base.c
.
Complete.
The latest Bus Pirate code and compiled firmware can be checked-out from
Google Code SVN
. Submit your code via the comments below or
buspirate@hackaday.com
.
UPDATE: Both issues were resolved. Thanks for your suggestions.

"content": "Sadly I don’t have a bus pirate yet and also I have no PIC prototyping board, so I can’t give any code. I’m bootstrapping a programmer right now.Regarding the interrupts:Reading the app note, the process is pretty straightforward. The Idea is that the interrupt vector table is in the same block as the reset vector. Because the bootloader needs the reset vector in place at any time, any safe operation would exclude writing to the first block of program memory (and also the bootloader code blocks, of course).To allow the user applications to use interrupts, the first memory block containing the vector table will be programmed once. The reset vector will get a jump to the bootloader and the interrupt vectors will get jumps to their own offsets in the NEXT block of memory, essentially “relocating” the interrupt vector table to the second block of memory. This block will be safe to overwrite by the bootloader’s operations, since the reset vector is not in danger.The interrupt vector table is usually populated by the linker, which puts jumps to the interrupt service routines at the right “magic” locations according to the code the user wrote. This can easily be modified by changing the linker’s script, i.e. tell the linker to put the jumps into the second block of memory, at the same offsets as before. An example linker script is included with the app note’s download.So let’s say that interrupt 1 happens, whose vector would be located at 0x04 in the memory (0x00 being the reset vector). Let’s also assume a block size of 0x10. The linker is told that he should place the jump to the interrupt service routine at (0x10 + 0x04). This is exactly where the bootloader’s “protective interrupt vector table” points to. So the PIC jumps to 0x04 when the first interrupt happens and from there gets the instruction to jump to (0x10 + 0x04). There the linker put the instruction to jump to whereever the actual interrupt service routine is located.Hope my writeup helps. I’d happily provide code, but as I said, I’m in the process of bootstrapping my PIC working environment. I first thought about porting the bus pirate to AVR (atmega32 or something the like), but then I thought it would be wiser to first build the supported platform and begin porting later, when I can test new code written for the PIC on the real device fist. So, getting an original PIC-based bus pirate would eventually speed things up a bit =DHope my writing helps. Feel free to ask if anything is unclear!",

For those wanting to do some hacking or kernel debugging on their G1, [macpoddotnet] shows how to make a
serial to USB cable
. He gathered enough information on the
Android platform google group
to be able to piece something together. He’s using a USB 2.8V serial TTL level converter, and lists several available that should work. Looks like a pretty easy build.

[Mike] sent in this project. It’s a robot, designed to print on wooden coins while people watch. It was built to be in the iHobby Expo 08 in Chicago. The main movement is controlled by a BASIC Stamp2, while the ink jet system is run off of a Propeller. The entire system has 4 servos, 3 stepper motors, a DC motor, a hacked breast pump, an ink jet head, and 5 IR sensors. in case you missed that, it has a breast pump. We’re assuming that’s the part that picks up the wooden nickels with suction. He states that the project was meant to be entertaining, so there are lots of superfluous and inefficient actions as you can see in the video after the break. Great job [Mike].

External Keyboard With An IPhone

Using an IR keyboard is now possible with a non jailbroken iPhone
. The folks at perceptive development have developed a custom interface that connects through the headphone jack. They had already developed the
serial modem
, so this was just another step at connecting peripherals. With some smart and small packaging, this could be a nice attachment to keep around. You can see a video of it in action after the break.

Carrying around a keyboard to access the Iphone kind of defeats the purpose of having such a portable device. One might as well get a UMPC (though I cannot recommend anything OQO makes – their batteries – a proprietary design – are total garbage and the chargers tend to fail, destroying the unit).All that said, it’s an ingenious hack and certainly deserves a spot on Hackaday. Nobody said the hacks had to be practical or useful. I settle for “interesting.”",

We did it to show how to plug a device into the audio port and do something useful with it.4. Yes, It supports music while typing5. The 3.0 SDK is certainly interesting, and a big part of the reason we aren’t taking this mainstream. However, there is, as far as we can tell, no HID support for Bluetooth, so A2DP and iPhone to iPhone communication only.

A team at UNC Charlotte has been
working on an autonomous vehicle
to drag a cart that has sensing equipment. Starting with a stock Honda ATV, different systems were added to give a
Renesas processor
control of the ATV. A model airplane receiver was attached to the Renesas to give remote control for Phase 1 of the project. Basically they’ve turned the ATV into a giant remote controlled car.
Later revisions will incorporate LIDAR, cameras, and multiple GPS units so the ATV can autonomously traverse most terrain with a high level of accuracy. Path planning will become a large part of the project at that point.

Hacked Instruments Compete

The
first annual Guthman Musical Instrument Competition
proved to be a very interesting place to be as hacked musical instruments competed for $10,000 in prizes. 60 people applied and 25 were chosen to show off their hacked together, strange, and whimsical instruments. There were all kinds of creations, from keyboard controlled motor cycle engines to tongue controlled synthesizers. We can’t imagine trying to pick some kind of a winner from the bunch this diverse.

Bios Level Malware

“Reformat it”. That’s pretty much our default answer when someone calls us complaining of malware and viruses. Though many can be removed, it can sometimes be quicker and less frustrating just to reformat it. Some of us even have specific ways that we organize all of our files just to make the quarterly reformat go smoother. Unfortunately, reformatting may no longer be the absolute cure.
Researchers have developed a piece of malware that infects the BIOS
. It is un affected by reformating or flashing. This means that it is also OS independent. They tested it on Windows and OpenBSD as well as a machine running VMware Player. This is a grim sign for the future.

Every motherboard handles BIOS flashing differently. Call this a virus or trojan: I modify HP’s firmware file to have the correct header but garbage elsewhere. I package this into a self-extracting and self-running archive. It flashes upon extraction without question. User has no idea as the computer has not restarted and it was all done silently. All the while, the installer for the software the user was looking for runs and the user thinks everything is fine.To make it more fancy, have a script or app check the manufacturer of the motherboard or manufacturer of the PC and have each flasher ready and compressed well into the archive (RK or 7-zip would work good).Even though Vista has UAC, many ‘power users’ disable it and others have no idea and just click Continue and/or type in their password not knowing. On XP and lesser, there’s virtually no control after the program is launched. The computer will be bricked in probably less than 30 seconds.I guess antivirus scanners should check for ‘BIOS modification code’ too now. Lucky for me, I use Linux.",

I am sure it would have no issues with linux.BSD and Linux and all other Unix-like OS’s are secure as in, you need root privileges to do anything directly with the kernel or special groups, runlevels, etc. By default, you are not given root privileges, unlike Windows (even Vista). I’d have to be dumb enough to want to run some random binary as root in order for any scheme like this to work. Beyond that, how many BIOS flashers use Linux? Personally I have found none and many are still using DOS, with the manufacturers asking their users to make DOS-bootable flash drives or FreeDOS live CD or something similar. HP and others have Windows-based flashers only.BIOS and how it works is pretty proprietary between manufacturers, especially when you compare Intel vs others. Foxconn is a good example. Some of their motherboards were found to have a hard time booting Linux because the ACPI implementation is proprietary.",

"content": "At least with Intel machines, the flash part will be locked and can only be unlocked in SMM. In some cases, the first 64K will remain write protected even after this and you can enter a recovery mode to reflash the rest of the chip. Backup BIOS banks are another system I have seen employed too.I’m not sure how much stock to put into the SMM ataacks as there are a few caveots with them, so they may not be enough to get through to flash the chip. But even if they did, assembly BIOS is not terrbly easy to patch because of it’s single linked nature. A little change here or there could potentally leave it nonfunctional.UEFI solutions may be a bit more vulnerable as it is more like modern software, but there are provisions for code signing, delivery of limited updated to the firmware (that must also be signed), TPM flash verification, and other security that should help to protect systems.But this particular hack does NOT use the mainboard BIOS. IT soulds like they are using PCI expansion ROMs.The question I have is if the card is still functional after the flash? Not all PCI cards have expansion ROMs, and not all those that do have writeable flash. So what card are they using? How are hey getting their code invoked? They say it’s 32 bit code but the option ROMs that run in POST are 16 bit. Is this instead a combination of an OS driver and the compromised PCI card? In this case, does the driver invoke the code on the PCI card?There has been a fair amount of “OMG, the BIOS is vulnerable” hyperbole lately. Yes, there is a lot of potental power there, but the way the code is put together now makes it difficult to attack. The new stuff is well aware that there are people who have been trying to attack BIOS for a while and new firmware may be vulnerable, but that this is also an opportunity to build security down at that level.",

Reader [Will R] sent in a
thermostat mod for his brew fridge
. His friends had found a perfectly fine bar refrigerator and wanted to repurpose it for brewing beer. A previous batch of microbrew had been mangled by the Australian heat so they wanted something that could maintain the perfect temperature. The fridge’s built-in thermostat wouldn’t rise above 5 degrees so they had to build their own. [Will] used a 10K NTC thermistor to measure the temperature. It’s connected to an ATtiny25 microcontroller that does the comparison and determines whether to turn on the compressor. He referenced SparkFun’s
relay tutorial
for the switching side. Although he didn’t etch a board for this project, the design file is included along with all the code on the project site.

One controls the high set point one controls the low. The inputs are reversed so that the one goes high when the temp is >= the high threshold and the other goes high when the temp is <= the low threshold.These inputs are put into an SR latch built from some NAND gates. This tells the compressor to turn on or off and also has LEDs to indicates the state, Blue for too cold, red for too hot, green for just right. An wall wort is powering a standard 7805 setup to run the whole thing.I plan on improving the entire circuit so that you can adjust the freezer to kegerator serving temp or fermenting temps. Also working on adjusting the whole thing with one large pot instead of two onboard ones.I was thinking of going with the ATiny micro but my EE friend convinced me analog was the way to go.Nice project though.

From what it does I’d say a µc and opamp solution are on par here, even costwise.For the 7805 in general you should use 100nF capacitors on the input and output, they will keep the IC from oscillating, which can happen if you don’t use them. See the datasheet for this, it’s strongly recommended. If you can’t make sure the outputvoltage is always lower than the inputvoltage you should use a diode from the output to the input (1n400x will do), or the ic might die from current flowing backwards into it.",

From the same person who brought you the
NES toaster
comes the
Super Nintoaster
. It looks like the most difficult part of the construction was extending the cartridge connector. The slider button works as the power button. The toast control now changes the brightness of the glowing red LEDs. Video introduction embedded below.

The creator of the
pac man modded roomba
is at it again. This time, [Ron Tajima] is going in a completely different direction. He has made a
baby cradle attachment for his roomba
. We don’t know what safety concerns there might be, but the baby seems OK with, so far. We’ve seen
robot baby cribs before
, but they cost much much more and don’t clean your house.

[derektroywest] has posted a detailed
step by step breakdown of making a Daft Punk costume
. They’ve done a great job, the overall look is very convincing. They include links to where to get each part as well as information on how they pulled it off. The helmets were inspired by the
timelapse Daft Punk helmet build
. As you can see in the video, they don’t have the entire visor made into a display, but the effect is quite nice, especially because it is multi color.

[Alex] put together this
lovely minimal LED project
. The square pixel matrix is soldered directly to the microcontroller in the same style as
EMSL’s Micro-Readerboard
. During the prototyping phase he used resistors to limit the current from the programming board. The final product doesn’t use resistors and manages the current draw by only turning on a single pixel line at a time. The
illustrated assembly guide
is very thorough and should help your create an equally compact device. Check out a video of it in motion below.

Researchers from Inverse Path showed a couple interesting techniques for
sniffing keystrokes at CanSecWest
. For their first experiments they used a laser pointed at the shiny back of a laptop. The keystrokes would cause the laptop to vibrate which they could detect just like they would with any laser listening device. They’ve done it successfully from anywhere between 50 to 100 feet away. They used techniques similar to those in speech recognition to determine what sentences were being typed.
In a different attack, they sniffed characters from a PS/2 keyboard by monitoring the ground line in an outlet 50 feet away. They haven’t yet been able to collect more than just single strokes, but expect to get full words and sentences soon. This leakage via power line is discussed in the
1972 Tempest document
we posted about earlier. The team said it wasn’t possible with USB or laptop keyboards.

[Barrett] sent in this
hack he did to an airsoft pistol
. He was using “tracer rounds” or glowing airsoft pellets and found that there was no commercially available way of charging them up with uv light before they are shot. He cracked open his pistol, removed the safety mechanism, and placed a UV led in it’s place. Now, when he turns it on, it charges up the pellets so they’re nice and bright. If he’s playing airsoft at night, won’t that bright purple light give away his position? yeah, we know he was probably just using that pistol to show the mod off.

That’s why they make them!Tokyo Marui has made a full auto tracer flash unit for years- and last year they came out with a new model I have. Works great. Tip- the big boys don’t use UV leds for lighting them up. The tracer units (shaped like a silencer with a red laser detection trigger for bbs inside) are always instantaneous high-powered strobe bursts. My full auto tracer unit was about 95$, but it lights up bbs at full auto speed from my Mac 10 Vietnam custom, at at least 15-20 shots a sec.Basically, each single bb gets a full tube of intense strobe flash- they light up like they’ve been painted with luminova or something. Works amazingly well. Granted, they take 4 AAAs, and you can burn them out in a long night, but it works great. I even made a custom mod and hid my tracer unit inside the massive Vietnam custom kit silencer you get. A single press, and fully silenced lightning pours out of my gun.UV will work, I’m sure, but professional gear uses HID strobes confined inside silencer type metal housings, with laser trip switches. If anyone seriously wanted one, I could call in Japanese and order you one. I can’t believe no one knows about standard Tokyo Marui equipment here!",

Making A Rail Gun

[Rp181] has documented his entire
rail gun build
. He takes us through collecting the materials and assembling the system. It required 18 400V 3900uf capacitors to get the 5600 joules he wanted. It looks pretty impressive, though a video of it wreaking havoc on something might have been nice. We’ve seen rail guns before, from
tiny ones for a robosapien
to
larger projects
very similar to this one. In his instructable, he touts this as a “green” system. The capacitors are aluminum and no gun powder is required to move the projectile. Anyone want to do the math to figure out if it really is any better? Maybe if he’s collecting his energy via a giant solar panel.

Hackit: Xbox 360 Hardware Failures On The Rise?

Joystiq has been tracking the new starlet of
Xbox 360
failures:
the E74 error
. It appears as the lower right light on the console turning red and an on-screen message telling the user to contact support with the error E74. The number of reported E74 errors seems to have risen since August 2008 and people are wondering if the more recent increase in errors are related to the release of the New Xbox Experience (NXE) Dashboard update. Did Microsoft reclass Red Ring of Death (RROD) failures as E74 to avoid warranty replacements?
From day one, the Xbox 360 has been plagued by hardware failures. So many failures that Microsoft ended up pushing the 90 day warranty
up to a full year
. Less than a year later they acknowledge the systemic RROD problem and extended replacement for affected consoles
to three years
. The RROD is named because of the
three red lights
displayed when the console failed. The culprit appears to be poor cooling of the console’s components. Components like the GPU would
overheat causing solder joints to fail
. People were able to repair their own consoles by
reflowing with a heatgun
. Microsoft has never officially disclosed why these systems fail. Our console
purchased on launch day
RROD’d, but [bunnie]’s
solder joint inspection
of it proved inconclusive. Every
Xbox
owner on Joystiq’s staff has had an RROD.
The E74 error is apparently not new. While Microsoft officially calls it a “
general hardware failure
“, users have been calling it a general video error since launch. It can occur when you have a bad video cable attached to the console. Users are
blaming the HANA video scaler chip
for the latest issues. There have been
five different motherboard versions
of the Xbox 360 so far. Each version upgraded the cooling and/or the size of the GPU and CPU. The HANA chip was introduced when the consoles started supporting HDMI. The original ANA video scaler on the Xenon board was a
quad-in-line style SMD package
with pins around the perimeter. The HANA chip on newer board designs is a ball grid array (BGA) package, which means it can fail the same way the GPU does for an RROD.
Did Microsoft change the error reporting on the Xbox 360 so they’d replace fewer consoles? No, we don’t think so. Is this a similar hardware failure? Most certainly. Unfortunately, E74 errors are only covered under a one year warranty instead of the RROD’s three year despite it being the same failure mode. Why are so many E74s happening now? There aren’t any hard numbers on how many failures there have been or how it compares to the RROD. We think that it’s just a result of more people having Xbox 360s with HDMI support now. A large portion of the Xenon 360s have been replaced with more reliable HDMI consoles, but that just means a larger install base of E74 prone consoles. More consoles means more possible failures.

But As people want more powerful compact electronic devices your going to see more and more. Any number of problems occur when using bga’s they are easily broken when torque is applied to the board. You can have air bubbles in the paste, microfractures in the solder joints and ROHS solder is useless. Rohs is effected by temp change much more then leaded solder pastes. Not to mention poor IC quailty could cause the exact same problem.Not to mention why is the 360 getting bashed so bad for RROD when sony’s PS2 had a 70% recall. I’m still using an Xenon box…. Meh",

I’ve seen quite a few with the infamous “no screen/lines” problem caused by failed balls on the graphics chip BGA, and fixing with a heat gun works for a while but never lasts long.There’s also a similar fault that affects the RAM on some Sony netbook clones (the little 10.1″ screen variety) where the BGA soldered RAM is flexed by the screen hinge and fails. In fact if you have a laptop which no longer boots it is well worth attempting to disable the onboard soldered RAM by asserting the /CS line connected to all the chips and installing a new SODIMM in the spare socket, have done this and it works.email mandoline at the cable and wireless guernsey isp dot net-A",

"content": "Um no. The 3RLOD/E74 is controlled by hardware. No update that Microsoft could have done could have made more RROD errors come off as E74 errors. And I strongly doubt that the NXE has anything to do with it. If you know anything about the RROD/E74 error, it is because of one of the BGA solder connections between the GPU and the motherboard breaking because of various forces on the chip and because of the expansion and contraction of heat, and heat is very poorly managed in the Xbox 360. When the system turns on, I believe it is the Southbridge IIRC that does a small hardware test of the system, if it sees that there is something wrong with the GPU, (or any other component for that matter) It’ll put out an error message. Depending on where the solder break occurs on the GPU, that is what error is put out. RROD (error code 0102 for those who are know what I am talking about) is the most common error, followed by E74, and then no video. If you turn on your console, and it does the green lights and you can hear the console booting up on your speakers but see nothing on screen, that means one of the solder balls broke connecting the GPU to the video out of the system, but the Southbridge has no way to test these connections so it thinks the system is good, but you end up not seeing anything on screen.There would be no way through a software update that Microsoft could change the console’s decision making to make it display E74 instead of 3RLOD so as to not have to doll out another free repair. They could only do that with a hardware update, the new Jasper consoles which have a new Southbridge MIGHT have been modified to do this, but I don’t see Microsoft going that low. And the Jasper consoles have the new 65nm GPUs which produce less heat which SHOULD reduce the number of failing consoles, but I don’t know how much good it is going to do because of the X clamps that hold the heatsinks on the chips which cause the uneven pressure that works with the heat to warp the motherboard and break the solder connections.So in conclusion, it is luck of the draw if you get E74 or the RROD. Microsoft can’t magically make your console e74 instead of RROD. Unless they were to mess with the core architecture of the system which might cost more money (hardware updates cost a lot of money) then just repairing the RROD consoles for free. And besides, new Jasper consoles shouldn’t RROD as much. In any case I am incredibly dissapointed at Microsoft’s attempt to fix the RROD situation once and for all. At the beginning of the life of the 360, sure it was excuesable, but now it still happens? Unexcuseable.",

"content": "John and brownsy67 are right. E74 is caused by a GPU solder ball fracturing. Heat isn’t so much the issue as the constant changing in temperature because the ROHS compliant solder (which is already poor) becomes weaker as the 360 heats, cools, and heats again…Like brownsy67 said, the whole problem could be solved with a redesign of the case and x-clamp brackets that hold the heat syncs in place. I would also add heat spreaders to the chips and clamp down the heat syncs on them tighter.The heat spreader would be important for distributing pressure evenly across the whole chip. In the case of my Elite, I solved E74 by placing plastic pieces around the edges of the chip to put pressure on those solder balls because when the die in the middle is pushed down, the sides tend to receive little pressure. This worked for a while, but the error came back as the plastic compressed under the pressure and heat. Thus, a metal heat spreader should do the trick…",

"content": "I have to agree with bob on the issue of whether or not software can effect hardware failures. We’re talking about, potentially, a heat issue here and how hard the software pushes the hardware can make the difference and push the systems that are borderline over the edge. Also, it would be interesting to know how long the people getting these errors have had their systems (on the average). As time goes on, it’s natural for the rate of product failures to increase as the number of systems in the wild increases and those systems have more time to fail due to fatigue.As for the BGAs, I’ve heard a number of things about that. What I heard, in relation to the 360 in particular, was that the manufacturer didn’t have a lot of experience with using BGAs and ROHS solder together. This lead to them not using the ideal temperatures for the process and lead to crappy solder joints. Not sure how true it is, but it’s one more possible way things went wrong.",

[Furan] wanted a way to let people know his status at the office. Maybe he didn’t want to be bothered, or wanted to let them know he was on break. His solution is to set up an
OLED display outside his office to display his status
. He’s using a 4d systems OLED display. He has a windows application that updates the status, with plans of making it synchronize with his messenger status. Its a fairly cool idea, but just watching the video, we have no idea what some of the icons are supposed to mean. We would possibly choose something a little more obvious and generic, like text stating our status. What would you use?

It sounds unbelievable, but it is true. You can harvest most of what you need for a simple
solar cell from powdered donuts and tea
. Powdered donuts have nanoparticles of
titanium dioxide
which is a “high band gap semi conductor”. This means that it can be used to make solar cells. The tea is simply used to dye the material so it can pick up the visible spectrum. The process is a bit too involved to be something you would just toss together in the field, but it’s cute nonetheless.

[Robert] sent in this tutorial on how to set up
USB sniffing in linux
. Useful for seeing exactly what is being communicated to and from your USB devices, this ability is built into linux. [Bert], the author, shows us the steps involved and how to filter it to get the data we desire. You can specify exactly which device to capture data from. His example, shown above, is a session with an Arduino.

[kero905] sent in this project he’s working on. It is an
open source hardware converter to connect Wii controllers via USB
. It uses an
Arduino
for its brains. It is still in development, the only controllers that work are the nunchuck and the classic. He notes that there are enough extra pins left to adapt to an arcade controller fairly easily. The code is available on the site, as well as a rough parts list.

No. People can just splice connectors as well. Theres lots of places to save money. The expensive hardware I am using is for prototyping ease. You only need an Atmega168, crystal, some diodes, resistors and capacitors.From mouser: Atmega8 = $3.66, atmega168 = $4.08, not much of a difference. If you try, you can get the code under 8k (its slighty over 8k atm) to put on a ATmega88 which is slightly cheaper.",

This is a simple hack that could come in handy one day. [Mooner] wanted to use a Kensington universal power supply with his Macbook Pro, but found the adapters and peripherals involved “hideous”. His solution was to
wire directly to the Kensington power supply
. It’s pretty simple really, only a couple resistors are needed. It’s nice to have someone else do the research for you sometimes. While his final picture does look neat and tidy, we just don’t know how much of an improvement he’s made to the aesthetics. What do you think?

"content": "Hi All-Thanks for the comments — both positive an negative…1: Why is this a “hack”?? Well, you could just go buy Apple’s MagSafe AC adapter and Apple’s in-flight MagSafe cord — but you still wouldn’t have a solution that allows in-flight battery charging. You also cannot use the Apple in-flight cord to charge/use your MacBook in a CAR. So, not everyone will need this “hack”, but some will find it very useful. I consider this to be a “hack” because the pinouts/resistor combinations are not published specifications. Requires some reverse engineering to figure out how to implement this… Just trying to save y’all some time and frustration.2: Why not just buy the “Mike Gyver” cable — uh, well, frankly, I think his shit is uglier than mine. There are way too many “moving pieces” in his implementation. AC adapter + Kensington cable + Kensington plug adapter + Mike Gyver cable — does that sound elegant to anyone?? Plus the whole point was to hack/make something, not buy it… Oh, plus my solution has a slightly higher output voltage — means your battery will charge faster on MacBook Pro models…3: Permanently attach the MagSafe cable to the wart?? Ok Diddle — you’re stupid. Just kidding. There are actually 2 good reasons I can think of… First: The whole point of a “universal” AC adapter is that you can carry the bag full of cables/adapters to power anything in a pinch. So, you pull my cord out, plug in a standard Kensington cable and you can power your other **insert brand here** laptop, iPod, phone or whatever you want… Second: Both connectors are proprietary — you can’t find either just the Kensington or Apple connector anywhere (at least not easily) — so, it is not like you can attach a virgin connectors to a clean cord and do away with the shrink tubing.4: Sloppy — wow, Albert, you’re an asshole ;). But yup, my soldering sucks. It gets better with each project, but it definitely sucks. Never learned how to do this in a professional setting, so it is all from trial and lots of error. And if you think MY shit is ugly, check out that ThinkPad “MagSafe” hack…-mooner",

[emuboy] sent in this neat hack where he
converted a GPS dock to bluetooth
(
google translated
). He has an ipaq rz1710 and a Kirrio GPS cradle. Apparently there were annoying problems when inserting the ipaq into the cradle. He decided that he would much rather just connect via
Bluetooth
. After tearing apart the cradle, he found the documentation for the
GPS
chip online. He ordered a
bluesmirf bluetooth modem
and got to work. The end result is something that could be concealed in his car and just connected to when he gets close enough.

In middle of all the
adding features that should have been available day-one
, Apple announced something really interesting for the hardware hacking community. The new
iPhone 3.0
OS will support application communication over bluetooth or through the dock connector using standard or custom protocols. From
Engadget’s coverage
:
10:19AM “They talk over the dock, and wirelessly over Bluetooth. Things like playing and pausing music, getting artwork — or you can build your own custom protocols.”
10:19AM “Now here’s a class that we think will be really interesting — medical devices.” Scott’s showing off a blood pressure reader that interfaces with the iPhone — wild.
10:18AM “Here’s an example — an FM transmitter. With 3.0, the dev can build a custom app that pairs up with it, and automatically finds the right station and tunes it in.”
10:18AM “With 3.0, we’re going to enable accessory developers to build custom apps that talk directly to that hardware.”
No solid connection specification has been published yet. We’re excited about the prospect of developing our own accessory hardware, but we wonder what sort of hoops you’ll have to jump through. Apple doesn’t have the best track record when it comes to approvals. Just this week they
denied MSA Remote client App Store entry
; it’s a multitouch client that uses the standard
TUIO protocol
. Prepare for similar roadblocks in the future.

Some pins even do serial TX and RX.If it’s just for the blood pressure and hartrate, the Arduino is HW enough, you don’t need no strongARM for that.",

Amiga Joystick Camera Cable Release
|
Caleb Kraft

[
"classic hacks",
"digital cameras hacks"

[] |
[betaj] shares this cool mod with us. They used an
Amiga joystick to create the shutter release
for their camera. The circuit is pretty simple, consisting of a battery and a switch. It interfaces with the camera via a USB type A connector. Its fairly simple, but will definitely get some comments from onlookers when it is used. Still, the best mod we’ve seen for a camera by far is the
chdk software
for Canon digital cameras. I’ll bet we see an NES controller version soon, despite the ergonomic nonsense of it.

Evil Mad Scientist Laboratories
spotted one of the
first images of the Arduino MEGA
. The board is based on the
ATmega1280
microcontroller, which has 128KB of flash,
4KB of RAM
, and 4KB of EEPROM. We haven’t seen any official specs yet, but the silkscreen shows 12 PWM connections, 36 Digital I/O, and 16 analog inputs. The post mentions 4 hardware UARTs and an I2C bus as well. No release date yet, but we can assume it’s soon since the hardware was already demoed at ETech.
Related: We added an
Arduino
category.

With Arduino, you just begin using the class Serial and write and read from it. It hides all the inner details of the MCU.The language syntax is similar… but Arduino is a level higher in abstraction.I guess 90% of Arduino users know almost nothing about basic electronics.

When compiling it randomly fails to give the size of the binary. The UI is just not very good. They would have done much better to use a premade editor widget (e.g. scintilla) with Qt.Secondly, it’s pretty badly documented. Most of the tutorials/examples only give you the code – no circuit diagrams. An example: The stepper constructor takes four ints as parameters – the pins which the stepper motor is connected to. But it doesn’t tell you which is which! You have to guess:http://arduino.cc/en/Reference/StepperConstructorEven worse, some of the library functions are buggy. The delay() function does weird random stuff when combined with PWM outputs in version 12, but not 11. It will also fail if the counter rolls over 0.Finally the hardware: It doesn’t seem like they’ll ever fix the gap in the sockets, and why they stick with giant USB is anyone’s guess. It’s the only thing I own that uses it. This isn’t too much of a problem as there are lots of good alternatives to the official arduinos.On the plus side, it is pretty cheap and easy to use (when it works)!

Adding ESATA To An Acer Aspire 1

In another installment of her ongoing efforts to mod the Acer Aspire 1, [tnkgrl] has
added eSATA capabilities
. During the
hard drive upgrade
she did, she used the spare PATA connection, leaving an SATA connection free. This time she has gone in and extended it to be accessible outside the case. To do that, she scavenged an eSATA connector from a desktop and simply wired it into the connections on the motherboard. She then mounted it flush as seen in the picture above. In the past she’s covered adding RAM,
internal Bluetooth
and the hard drive upgrade.

We’ve been
eagerly anticipating
this, [Larry] has published the
entire build of the Shmooball gun for 2009
. This design is more compact and elegant than the one for
2008
and has a slightly more Ghost Buster’s aesthetic about it. The pictures are great and there’s lots of good tips along the way. We can’t wait to see what they make next year. How about a
gattling
version?

Cockeyed.com
is a peculiar site. It is spattered with links in an almost unintelligible manner, but if you dig hard enough, or just click randomly, you can find some pretty fun stuff. One nice writeup they’ve done is how to
replace the lens in their point and shoot camera
. This one happens to be a Canon Powershot sd750, but it will give you an idea about how difficult it can be for any point and shoot. The lens assembly couldn’t be replaced until almost every single piece had been disassembled. There are tons of pictures showing the process and the final result. Though the install was a success, his replacement lens was already beat up pretty bad. Looks like he’ll have to go through it all again.

I’ve accidentally set it off on 2 rebuilds. The first just died, the camera wouldnt work at all. The second one actually shocked me, causing me to tear the ribbon cable I was holding. Make sure you don’t touch the terminals with your skin or a screwdriver.That said, replacing misc parts inside isnt all that hard. Most Canons are more or less the same idea inside, once you’ve taken one apart they’re all pretty similar.",

In a time when marketing is all around us, companies often have to come up with new and creative ways to get us excited. Some go the viral route, others hire famous spokes people.
Samsung did well with this idea
. Let some computer geeks build something awesome and have fun with it. They chained 24 drives together to create a whopping 6Terrabyte array. They run various speed tests and even test the drive integrity by bouncing on a trampoline while dangling them from their chords. Yeah, they make the computer geeks a little geekier than they need to be, but who didn’t get excited to see those transfer speeds?

We covered SparkFun’s new
RGB button pad controller
a few weeks ago. This is a full-color clone of the
monome
interface; a 4×4 grid of buttons with tri-color LEDs underneath. Each LED has
24bits of color control
, for more than 16million color combinations. Up to 10 panels can be chained together to create huge button grids, like
SparkFun’s Tetris table
. We previously used a smaller version in our
RGB combination lock
.
We asked SparkFun to send us the SPI version of the button controller to test. This is a new product developed in-house at SparkFun, with open source hardware and software. Read about our experience interfacing this board below.
4×4 RGB button pad controller SPI (SparkFun #
WIG-09022
, $39.95)
The button pad controller is a bare PCB, we also received a button pad cover (SparkFun #
COM-07835
, $9.95), and two of each bezel (SparkFun #
COM-08747
, #
COM-08746
, $3.95). The SPI version we’re working with can be driven directly by a microcontroller, or by a USB ‘master’. The USB controller version has an additional microcontroller and FTDI USB->serial converter for PC connectivity.
When the button pad arrived, we immediately sat down with the datasheet and tried to interface the board with our
Bus Pirate universal serial interface
. The protocol described in version 1 of the datasheet didn’t work, at all.
SparkFun open sourced this project, so we determined the correct interface protocol from the source code for the
button pad SPI
(ZIP) and the
button pad USB controller
(ZIP). We figured out most of the protocol from the source, but it still took help from SparkFun’s engineers to uncover some of the undocumented, finer points of interfacing the board. Version 2 of the
datasheet
(PDF) accurately depicts the interface protocol.

The button pad’s SPI signals are described as they relate to the on-board microcontroller, which is opposite the usual notation. The MOSI (master out, slave in) signal is actually the board’s data output, and MISO (master in, slave out) is the data input.
We tested the button pad with the Bus Pirate, but the same basic principals apply to any custom microcontroller code. The board runs at 5volts, so we powered it from the Bus Pirate’s on-board 5volt power supply. The SPI interface operates at 5volt logic levels, so we connected the Bus Pirate’s
pull-up resistors
to the 5volt power supply and enabled them on all signal lines.
We interfaced the button board using the Bus Pirate’s raw3wire library. Raw3wire is a software SPI library with bit-wise operations. The hardware SPI library only allows full byte operations which aren’t granular enough to interface the board. We put the Bus Pirate in raw3wire mode (menu option M), and chose the HiZ pin option because the pull-up resistors will hold the bus at 5volts.
RAW3WIRE>l
<–configure bit order
1. MSB first
2. LSB first
MODE>2
<–least significant bit first
LSB SET: LEAST SIG BIT FIRST
RAW3WIRE>W
<–enable power supply
VOLTAGE SUPPLIES ON
RAW3WIRE>
The button pad communicates least significant bit first, so we also configured the library to communicate LSB first. Finally, we hit capital ‘W’ to enable the Bus Pirate’s power supplies. The button board will flash each color momentarily as part of its power-on self-test.
Single/multiple button board setup
Each board needs to be configured for single or multi-board use. Boards come pre-programmed for single-board operation, but it might be a good idea to set the configuration anyways. The board configuration is permanently stored in EEPROM, so it only has to be done once.
RAW3WIRE>[\_
<–take all signals low
CS ENABLED
<–CS enabled is 0volts
CLOCK, 0
DATA OUTPUT, 0
RAW3WIRE>
A special sequence places the board in configuration mode. Begin with all signal lines low (]\_).
RAW3WIRE>-^ 1 1
<–set single board operation
DATA OUTPUT, 1
<–data high
0x01 CLOCK TICKS
<–one clock tick
WRITE: 0x01
<–config option 1, number of boards
WRITE: 0x01
<–set the number of boards
RAW3WIRE>w
<–small ‘w’, power off
VOLTAGE SUPPLIES OFF
RAW3WIRE>W
<–capital ‘W’, power on
VOLTAGE SUPPLIES ON
RAW3WIRE>
To enter configuration mode, take the data line high (-) and send one clock pulse (^), but
leave chip select low
. The board is now ready to accept configuration settings.
The first byte sent after entering configuration mode tells the board which setting to modify. Currently, only the number of boards can be configured (0x01). Next, send the number of connected boards, between 1 and 10. we sent 1 because we’re interfacing a single board. Reset the board and it will light a LED corresponding to the programmed number of boards.
Set colors and read button status
Now we’re ready to send color data to the board and read the button status. First, note that the CS (chip select) signal is opposite normal conventions. Usually CS activates a chip when the signal is low (0volts), and idles it when the signal is high (5volts); this is usually denoted by /CS, #CS, or !CS. Instead, the button controller is active when CS is high.
A 64byte transaction sets the LED colors and retrieves the button status. The first 16bytes program the red level for each LED, followed by 16bytes of green, and 16bytes of blue. Finish by reading 16bytes from the board to get the status of each button. Buttons data is sent as 0x00 if pressed, and 0xff if not pressed. The datasheet recommends a 400us delay between writing the color frames and reading the button data, but the Bus Pirate is slow enough that we won’t worry about that.
The protocol is simple enough, but there’s one
major
catch. The clock line
must
be high before raising CS, or the bytestream will be off by 1 bit. For this reason, many hardware SPI modules won’t work with the board. This isn’t a problem if your microcontroller lets you twiddle pins that are controlled by a hardware module, but the micros we’ve worked with
don’t
allow this.

RAW3WIRE>
This command sets every color of each LED to full, and reads back the 16 button status bytes.
We first set clock high (/), and only then can we raise CS to 5volts (]) and begin the data transaction. 255:16 is a repeated command that sends the value 255 sixteen times. As each color channel has 8bits of intensity control, 255 is 100% on. We send 255 a total of 48 times, once for each color of each LED. Finally, we retrieve one 16byte frame of button data (r:16) and lower CS to end the transaction ([). The button values are all 0xff, indicating that no buttons are pressed.

Here, we set the blue level of every LED to 50% (128) and turn off all other colors. The button output now shows that button 0 is pressed.

This example shows how to address single LEDs. This time we actually write out all 16 bytes of the red color frame. Buttons 0-3 and 8-15 have a red value of 0 (red off), buttons 4-7 are set to 100% red (255). All green and blue LEDs are off (0, 0%).
Conclusion
It was really frustrating to get this board working because the first version of the datasheet had so many errors. SparkFun’s engineers and support were really helpful, and posted a corrected datasheet within days. As long as you have the updated datasheet, this is an easy board to work with.
We’d like to see a firmware update that eliminates the need to keep the clock signal high before raising CS. This quirk makes the board incompatible with many hardware SPI modules, leaving slow bit-bang routines as the only interface option. Fortunately, the source code is open and available to anyone who wants to make this change.
The button pad controller is a really neat board, and we look forward to using it in a future project.
Hack a Day review disclosure
: We asked for a free board and SparkFun sent it to us. We had a terrible time getting it to work with the instructions in the first version of the datasheet, we documented that experience here.

We love our pets, but sometimes we just can’t keep up with them all the time. Sometimes, we need some automated playmates for our furry pals. [Kateham] has built a
motion detecting cat toy
to keep their cat content and active. Their price list was roughly $5 for the whole project, but they did obtain things like microcontrollers from family members. Some places they did manage to cut costs were to harvest various parts from a VHS deck. Its great to see kids not only hacking, but recycling as well. Great job [Kateham]. This project is like a simpler version of the
laser pup
.

Serious rocket hobbyists aren’t content with merely launching their rockets into the air. [wwgd] wants to have an on board computer to control his flights and log the data. He doesn’t quite know how to do it all yet, so he’s starting with the basics. He has
built the basic GPS data logger
using an accelerometer, a GPS unit, and a BS2P microcontroller. The overall weight is 62 grams and it can record for the whole 5 minute flight. At roughly $200 though, we’d be thinking twice before launching it into the stratosphere.

BatchPCB is a low-cost PCB manufacturing service run by retailer SparkFun in cooperation with Gold Phoenix. Using them, you can get your design prototyped for as little as $2.50 a sqin. We used the service in our “
How-to: Prepare your Eagle designs for manufacture
“. The service collects orders until they have enough to manufacture an entire panel. It may take time to get the boards back, but they’re high quality. BatchPCB just
added a brand new feature
: Now anyone can list their verfied design files on the ‘
products
‘ page for other hobbyists to order runs of. Yes, people could always upload free designs themselves, but this makes it much easier to order a board even if the designer has no plans of making a kit of it.

[Gabe] sent in this
project summary from his rocketry club’s yearly project
(pdf). The goal was to build a rocket that would go up to about 800 meters and eject a robot that would pilot itself to a destination on the ground for re use. There’s tons of great information from what hardware is in the robot to hardware design for the ejection mechanism. There are great pictures of the final build, not so many of the construction itself. The project seemed to go well until
EMI
problems caused everything to fail during flight. If you’re interested in seeing more from the club, check out
their site

AndroidAndMe is running a
bounty program for Android applications
. Users can request a specific application and pledge money to be awarded to the developer who delivers the functional app. [Alec Holmes] just fulfilled the first request by creating Torrent Droid. You can use the app to
scan media barcodes and then download the related torrent
. It uses the phone’s camera to capture the product’s UPC barcode (similar to
Compare Everywhere
‘s price lookup) and then searches major torrent sites like The Pirate Bay to find a copy that can be downloaded. After getting the .torrent file, the app can submit it to
uTorrent
‘s web interface for remote downloading. The app will be released later this month and you can see a
screenshot tour
of it on Alec’s blog. It’s doubtful that an application like this would ever clear Apple’s App Store approval process.

Arduino Mouse Trap

"arduino",
"mouse trap",
"tupperware"
] |
[scott] had a need to capture a mouse and wanted to learn about how to program an arduino, so he built an
Arduino controlled mousetrap
. It is made from things he had laying around the house, like some
Tupperware containers
and wooden rods. The program is pretty simple, when a trip wire is touched, the servo jerks the wooden rod out of the way, closing the container. You can see it working after the break. The trip wire seems like a big failure point. he states that it is just a wire, slightly above a tin foil strip. That seems like it would only be a tiny area that the mouse would need to touch to trigger it. What better switch could he design as cheap and quick as possible?

Now… doing capacative sensing or adding a delay without using a micro would be a much cooler (though still not too difficult display of hackery.And for the person who remarked about not understanding capacative sensing… I’m sure there are tutorials out there… basicly you build an RC oscillator, where the mouse( or your finger) could come into contact with the capacitor part, and you time the circuit’s oscillations. When someone touches the capacitor, it takes longer to charge as now there’s more capacitance in the system. The delay indicates a sensor event.",

IPod Touch 2G Jailbreak Released

The iPod Touch 2G jailbreak was
first shown in January
. It had to be applied every time the iPod was booted. The iphone-dev team just released the
24kpwn LLB patch
to allow for a persistent jailbreak. The team had been hanging on to this patch because there was the possibility the exploit could be used on future iPhone versions. Unfortunately, a group started selling the code, so the team was forced to release it for free. iPod owners are certainly happy though. There is a tutorial available for
updating a factory reset iPod
(
backup link
). The team will include the patch in future official tools.
UPDATE:
[cptfalcon] pointed out a post that covers the
technical details of the exploit
.

There’s a lot of great apps that have been banned from the app store, because either they replicate an itunes function, or for some reason or another apple doesn’t want people having that function. Docs (reads word/excel/pdf files), Cycorder (use the camera as a video recorder), Podcast programs, they have all been rejected from the official app store, but you can still get them if you jailbreak the touch.Also, with installous, you can pirate almost anything in the app store.",

I never lug my laptop around and wont use a new music player for a long while.Itunes is awesome as well, it is easy to find what i want when i want. Although i would rather have the physical CD It is very convienent to hop on itunes buy what i want and have it instantly. DRM is a nessacary evil, it hinders pirating slightly. It stops me from buying a CD and giving it to my freind to copy, which means he might buy it.So please dont be so ignorant of a very good thing.

[Jerry] lost his finger in an accident and has since added a
prosthetic USB flash drive
in its place. It’s making the best of a bad situation; there’s nothing wrong with a little voluntary cyborgization. At least it’s not as invasive as some of the implants
we’ve seen before
.
UPDATE:
Here’s the entry on [Jerry]’s personal blog

I’m trying to keep this G-rated!)3) When I use a jump drive, I insert it in the USB jack and then leave it there until I’m done. The described “solution” requires the guy to tie up one of his hands for the entire duration of use of his drive… unless he removes his finger and leaves the USB gizmo in the jack. If that’s the case, then how is this any better than having the drive on a key chain or a lanyard?I really enjoy reading about the interesting things that people build, modify, and hack.

[Pattie Maes] from MIT’s Media Lab showed a really interesting augmented reality demo at TED this year. It’s a
wearable projector that lets you interact with any surface
. A camera tracks the gestures your fingertips make and performs related actions. She shows several uses: projecting a dial pad on your hand, displaying additional info on a product you’re holding, and taking a picture when you form a frame with your hands. The current equipment cost is $350, but that would be reduced in a dedicated device.

RFID Controlled Phone Dialing

In an attempt to create an easier to use interface for the elderly, [Stephen] has put together this
phone prototype which uses RFID tags to dial
. It is common for our motor skills and eyesight to deteriorate as we get older. There are special phones out there, but generally the only changes they make are enlarged buttons and louder speakers. [Stephen] had the idea to make a system where an elderly person would hold up a picture of the person to the phone and it would dial. He picked up an RFID card reader and an Arduino. The code for the RFID reader was already available, and with minor modifications to prevent multiple swipes from hand tremors or slow movements, he was able to get it working pretty fast. The Arduino then sends the data to an ioBridge to make the call.He’s using
Google voice
to physically place the call, so you could probably adapt this to other services as well. You can see a video of it in action after the break.
[youtube=http://www.youtube.com/watch?v=B-NNGHiohzE]
[Stephen] points out that even though he’s using an iPhone in the video, this project should really work with any two phones.

If one of their friends moves or dies, you can keep them from making embarrassing mistakes and reduce the potential aggravation that they may have (which would limit their willingness to use the system).Like mentioned above, retraining them to not pick up until the phone rings and to be patient for the ring after might be the hardest part of the entire thing. If you could rig up a phone to anounce “dialing” when ever Google Voice calls and automatically turn on a speakerphone instead, that might be a good step to improving usability.That said, this is a really great idea.",

While playing with an ATmega168, [Jeff] programmed the
RSTDISBL fuse bit
. This pretty much makes the chip useless in most cases. [Jeff] didn’t want to give up on it though, so
he built a system to program it using the rarely used high voltage parallel programming mode
. He used an Arduino, a few lines of code and a few spare parts to make it. After sharing the idea with some fellow programmers, he decided to make an Arduino shield specifically for this purpose. You can use this to reset almost any fuse to rescue a chip. If you are a die hard AVR person and never started using Arduino instead, the
STK500
actually has this built in.

You should all know the drill by now. New electronics hit the market and someone has to post pictures of it spread open bit by bit. The
new shuffle is no different
as iFixit shows us. There are some very nice pictures of the entire process. As you can see, most of the space is taken up by the battery. The thing that is probably most striking here is the main problem that many people have with it; there aren’t any buttons.

MacMod member [EdsJunk] has modified the Apple logo on his MacBook to
act as a second video display
(
cache
). There’s a video embedded below showing it playing Quicktime videos and the iTunes visualizer. Unfortunately there aren’t any details of the hardware used. From the display settings, it looks to have a resolution of at least 640×480. We hope to see more details soon.

Laser Etched Kindle 2
|

"kindle",
"ladyada",
"laser etch",
"xkcd"
] |
After seeing the
xkcd comic where they call the Kindle2 the hitchhiker’s guide
, [Ladyada] couldn’t help but
laser etch the Kindle 2
with “Don’t Panic”. We think it looks pretty good, if a bit bubbly. You can see the video of the entire process after the break. Now that xkcd has infiltrated our interwebs, hearts, and minds, maybe he can put just a tiny bit of effort into learning to draw. If you don’t have access to a laser etcher, you could always
make your own
. Just be careful you don’t accidentally go full out and cut your kindle to shreds.
[youtube=http://www.youtube.com/watch?v=N2TGO-Q2F9g]
The kindle isn’t the strangest thing we’ve seen etched by far. We’ve seen
Pizza cut by laser
and even
laser tattoos
.

[Chris] sent in the
Thermosmart
. It is an Arduino controlled thermostat. It has a web interface which allows him to see the current temperature and make adjustments from remote locations. He can set heating or cooling to on, off, or auto and adjust the ranges as well.
We’ve seen similar done with an Arduino before
, even
one with a nice LCD interface
. This could possibly be useful for
remote plant monitoring
as well.

With the recent announcement that the only controls for the Ipod shuffle will be on the headphones, many were let down. [James] has come to the rescue, showing that you
can just solder new ear buds on the end of the wires
. Though this may not be the perfect solution, especially if your cable gets damaged, at least you can get a little better sound. This is a great example of something to show kids. It’s not too difficult and teaches them that if we’re not happy with something, we can hack it.

Sure there’s a “duh” aspect to the modding of headphones, but I get A LOT of emails thanking me for clearly explaining how it’s done.

The
CupCake CNC Kit
is the flagship product of MakerBot industries, a joint venture between [Bre Pettis] and [Zach Hoeken]. At $750, it comes with all the motors, belts, body pieces, bearings, belts, and other pieces to assemble it. You could be printing your own 3d objects in a matter of hours with this. 3D printers with only slightly larger capacities can run thousands of dollars. The only advantage to some of the commercial products might be resolution. They don’t give much as far as technical data as the unit isn’t available yet. They should start Shipping before April 15th, so they can’t be far off. This could possibly be a competitor for the
RepRap
. Since RepRap doesn’t offer a complete kit, we’ll have to speculate. We’ve seen estimates from $500 to $1000 to build one.

A commercial casting house will use a lost-wax investment casting de-waxer that operates between 1800F – 3000F.. This is more than enough to properly degrade ABS ( ie burn it from the inside of the mould) , so you can just send the cast object to a comercial caster, and they will be able to cast it just like it was wax.Option 2 – Room temperature at home – ABS plastic is soluble at room temperature with esters, ketones, acteone and ethylene dichloride, so you can take a plaster cast of the ABS object with water-based plaster, and soak the resulting plaster in the solvent of your choice to remove the ABS. ( I have not tried this) Dry the plaster mould thoroughly at below the vapor-point of your chosen solvent before casting , as the solvents are flamable.",

When traveling with a laptop, we often find that the list of peripherals that we have to attach can get pretty long. Especially if it is an older laptop without wireless built in. [Dawning] has
taken steps to consolidate some of his peripherals
(registration required)by cramming a USB hub and a wireless card into his mouse.
He started by dismantling a USB hub. After placing the board in the mouse to see how it fit, he realized that he was going to have to reduce the size. To do this, he removed the USB slots themselves. This forces him to wire things directly to the board, but saves a ton of space. Next, he took the guts from a USB wireless adapter and wired them up. The decorative LED in the mouse was then moved to the wireless card. This way he could see light flicker with his network traffic. At this point, that’s all he’s added, though there’s still plenty of space for other items. He notes that he’ll probably add some storage or a CF reader. The only problem he has encountered is that his mouse tends to get warm during use. What peripherals would you put in there?
Update: [Dawning] let us know that he didn’t actually remove the LED from its original location. He connected a wire from the wireless adapter that causes the LED to short when traffic is going through. Also, there’s a video which you can now see after the break.

Which isn’t surprising.The Hub I used does have a port for an external power supply. I suppose if one wanted to, they could remake the USB cable coming in to the mouse case to also include a cord to a power source for the hub. This could look fairly clean using some shrink-wrap to make a new cable. However, personally I wouldn’t like that as the connector would then have two things coming out and the power adapter would have to include an big transformer (AC adapter) if it was to go right to the wall.People hacking netbooks might be able to tap some additional power source inside their netbooks, though I’d be worried to pull anything out. USB tends to only provide juice on a new connection for a brief time if no device brains are actually detected. Or so I’m led to believe.",

Dallas/Maxim’s
DS1801
is an audio volume
potentiometer
with a simple
SPI
interface. This chip has two channels of volume control that might be useful in a DIY audio project. We previously looked at the
DS1807
, a similar part with an I2C interface. This week we’ll show you how to use the SPI version.
DS1801
SPI digital audio volume potentiometer (
Digikey search
,
Octopart search
, $6.50).

We connected the DS1801 to our
Bus Pirate universal serial interface tool
as shown in the table. We used the Bus Pirate to demonstrate this chip, but the same basic procedures apply to any microcontroller. The DS1801 power requirements are flexible, it works at either 3.3volts or 5volts, we used a 3.3volt supply.
The DS1801 has an SPI interface. The data output pin can be used to cascade multiple DS1801s. We used the Bus Pirate’s SPI mode with default options to interface this chip.
The DS1801 SPI protocol is described in figure (a) on page 4 of the datasheet (shown above). Note that the SPI enable signal, called RST on the DS1801, is actually opposite standard notation. Data input is active when RST is high, and inactive when it’s low.
Each DS1801 has two audio potentiometers with 64 steps of volume control. 0 is full volume, 63 is the lowest volume, position 64 is mute. Setting the volume is really simple; just raise the RST signal, clock in the volume level for each potentiometer, and lower RST to enact the new settings.
SPI>A 64 64 a
AUX HIGH
<–RST pin high
WRITE: 0x40
<–mute setting channel 0
WRITE: 0x40
<–mute setting channel 1
AUX LOW
<–RST pin low
SPI>
Here, we set both potentiometers to mute (64). First, raise the RST pin to 3.3volts (capital ‘A’,
silly CSS
). Next, write the mute setting for each (64 64). Finally, lower the RST pin to enact the new settings (small ‘a’).
SPI>A 0 0 a
AUX HIGH
WRITE: 0x00
WRITE: 0x00
AUX LOW
SPI>
Now we change both potentiometers to full volume by writing a 0 to each. The sets a resistance level of 0, or 100% of the input volume.
SPI>A 0 64 a
AUX HIGH
WRITE: 0x00
WRITE: 0x40
AUX LOW
SPI>
Finally, we set a different volume levels on each potentiometer. Pot 0 is at full volume (0), pot 1 is muted (64).

[Travis Goodspeed] posted a preview of what he’s working on for this Summer’s conferences. Last weekend he gave a quick demo of
sniffing AES128 keys on Zigbee hardware
at
SOURCE Boston
. The CC2420 radio module is used in many Zigbee/802.15.4 sensor networks and the keys have to be transferred over an SPI bus to the module. [Travis] used
two syringe probes
to monitor the clock line and the data on a TelosB mote, which uses the CC2420. Now that he has the capture, he’s planning on creating a script to automate finding the key.

Former Hack a Day contributor [Will] has been using a
Eye-Fi
SD card to
automate his photo transfers
. Unfortunately this requires using Eye-Fi’s software and talking to their servers. He used [Jeff Tchang]’s
replacement server written in Python
to recieve the images from the card. [Will] manages his own online photo gallery using
Gallery 2
. To get the images uploaded, he added a call to
GUP
. Now all of his photos are transfered just as easily as with the standard Eye-Fi but without all of the middleman.

[Sleepydog] just sent in this
cool video
of a patch cable he made with a built in
EL wire
. He’s using a Power over Ethernet router to control which ports have power. He states that this would allow easy identification of specific cables in the mess. While the proof of concept seems completely functional, and the idea is nice, we have to wonder if the cost to put in all the extra hardware would be worth it. Each cable would have to have its own inverter, not only driving up cost, but possibly adding interference. That does not mean we don’t want this desperately, we do. But we want it just because it looks cool. He needs to choreograph this to some music now and make his entire server room into a fancy display.

Tethering The Kindle 2

"Misc Hacks"

[
"kindle",
"tethered",
"usb"
] |
This is not an article on how to use your Kindle’s internet connection with your computer. We’ll let [Jesse] explain why:
This is not a tutorial about how to use the Kindle 2’s Sprint connection from your computer. I don’t know that it’s possible to do so without making changes to the Linux installation on the Kindle. I do know that abusing the Kindle’s Sprint modem like that would upset Amazon a great deal. Bear in mind also that Amazon know where you live. They know your Kindle’s serial number and thanks to the built in GPS, they know where you are right now.
What this is, however, is a
nice tutorial on how to connect your Kindle to your computer
so that it can use your computer’s internet connection. The instructions assume you are using a Mac, so you may have to adapt it if you aren’t. Basically you put the Kindle in Debug mode and tell it to use the USB tether for it’s network connection. This should allow not only a faster connection, but possibly a chance to see what exactly they are transferring back and forth.

Here’s a quick prototype from [Travis Goodspeed]. It’s a
smart card built around an MSP430 microcontroller
. We’ve used the MSP430
in the past
because of its low power demands. He says this business card currently supports 1.8V to 3.3V, but a future design will have 5V as well. Technologies like
Java Card
exist for running applets on smart cards, but a familiar microcontroller like the MSP430 could certainly make development much faster. Knowing [Travis], there’s a reader somewhere about to go through some serious
fuzzing
.

From that point, you could then apply the password to your actual smart card and do what you wish with it, within certain limits.",

So I dont want to see some 19 yr old kid do this hack, and publish on a site a guide like “I send 0x3F and it returned 0x9C”, and have a sat co ruin his future via a lawsuit he cannot defend himself against. what i just described Rather, I want to see him do it, but I want him to be aware that he needs to do so more carefully than if he posts the same info about the smartcard at the laudromat. In short, if getting into some hot water at the laundromat is like a garter snake, I’m trying to say the sat co’s are the black mamba.

We’ve heard about the idea of using browsers as distributed computing nodes for a couple years now. It’s only recently, with the race towards faster JavaScript engines in browsers like
Chrome
that this idea seems useful. [Antimatter15] did a
proof of concept JavaScript implementation
for reversing hashes.
Plura Processing
uses a Java applet to do distributed processing. Today, [Ilya Grigorik] posted an
example using MapReduce
in JavaScript. Google’s
MapReduce
is designed to support large dataset processing across computing clusters. It’s well suited for situations where computing nodes could go offline randomly (i.e. a browser navigates away from your site). He included a JavaScript snippet and a job server in Ruby. It will be interesting to see if someone comes up with a good use for this; you still need to convince people to keep your page open in the browser though. We’re just saying: try to act surprised when you realize Hack a Day is inexplicably making your processor spike…

"content": "while this might be an interesting conceptual demonstration, java is generally very slow when compared to other high-level languages like c/c++ — and certainly when executed in the confines of a browser. it doesn’t look like they have any performance benchmarks in their article, but my guess is that the java running in a browser is probably anywhere from 10 to 1000x slower than similar code written in C and executed in a shell. (it’s been a while since I’ve compared java/c speeds, so maybe this has increased a little in the last few years, but i’d imagine the gap is still quite large).this would essentially mean that you’d have to have anywhere between 10 to 1000 machines running a java client to do the work of a single machine written using a high-performance computing language and libraries. that being said, i’m certain there are ways you could get more performance out of java — maybe by implementing a special set of libraries that do certain computations particularly efficiently and natively on a machine — but it’s still likely a very large source of inefficiency in the current model.still, a neat idea! i especially like the whole ‘let me compute a tiny bit for you using idle cycles in a very controlled way instead of showing me tons of ads’ idea a commenter above just suggested. i suppose in any case, even if the efficiency was only 1%, that’s potentially a lot of cycles that were otherwise unused.",

While it is probably still slower than C++ the latest generation of browsers are including new javascript engines that take the javascript and compile it into a binary object. While this slows down the initial load, after that it goes light years faster.And the benefit here is that rather than having people download a client, all they need to do now is navigate to a website to join the computing cloud.Also, just thinking about it a completely useless but interesting sidenote is that this will run on anything that can run javascript, which is far more devices than can run any other distributed computing tool.",

"content": "Yes, modern javascript engines compile to native code and are fast. But for something computationally intensive I think there’d still be a significant slowdown compared to C.The main reason I think this is that Javascript is a dynamically-typed language, which means that the interpreter has to do lots of checking at runtime to know what type of an object it’s dealing with, or do sophisticated analysis at load-time to predict the type. (Contrast with C in which you tell the compiler the types of your variables).I don’t know the extent to which modern browsers can do this analysis. I’m guessing that the speed difference between Javascript and C is significant enough to make this system unable to compete effectively with other distributed computing platforms.I also think a conventional application which runs in the background and starts automatically is likely to contribute a lot more CPU time than a web page which the user has to deliberately load and leave open.",

The issue that most distributed computing projects face is a lack of computers actually computing. This approach would trade off some serious power behind each user, however it could theoretically increase the number of users exponentially.Imagine if for example, someplace like Facebook or Addicting Games implemented something like this behind the scenes. (Disregard any legal issues/ToS issues/ etc for now.) While none of the users would actually contribute enough to notice a slowdown of the site, each and every user would provide some small amount of processing power. This by itself would not be much, but now compare the demographic of users on that site to the demographic of users running any major distributed computing client. I think you will find an exponentially higher number of users behind the website.This is definitely an interesting idea, and I can see it taking off it it is approached in the right way.",

[Tobe] shares living accomodations with a few other people, so he
built this tool to help them all communicate
. using a Samsung SPF-83v wifi enabled picture frame, he’s made a central location for things like shopping lists and messages. He uses PHP for the database accessing and writes it all to an image using
gd
. Every 15 minutes a cron job runs that pushes the updated image to the picture frame.

[Peter] sent in this writeup on how to
build a remotely accessible thermometer
. The hardware side is pretty easy on this one, all you need is an Arduino, a resistor and an thermistor. The software is where the main focus is. You can check the temperature via command line, but also via email. It can also tell you the temperature using the host computers sound hardware. You can see a video of it in action after the break. We have to wonder
why
he
didn’t

it twitter.

"content": "I love these kinds of projects. While the hardware aspect of this one is ridiculously light (a resistor and thermistor…), the follow-through on code is nice. I plan on using the arduino platform for a full redo of my home’s heating system.Any thoughts folks?:– Nokia N810: wall mount this tiny computer– Web server: install a small web server on the N810– Temperature sensors + XBee: sense temperatures with some regularity (minute by minute? 5 minutes?)– Arduino: concentrate the serial signal from the XBees, located throughout the house– Relays: I need to better understand how the relays in my hot-water radiative heating system work, but I’m pretty sure all I need to do is close a zone’s circuit to turn it on, and open a zone’s circuit to turn it off.– Code: this will be the long pole in the tent. While I’m a pretty good coder, it’s been ages since I’ve written anything but net code (php, js, java, mysql). Gotta make an interface with arduino to read data and display it on the (private) web.This will allow better charting of my temperatures throughout the house, allow me to segregate zones, better understand their interplay, etc.Anyone wanna play?",

Also the ease of wiring up an additional 1-wire sensor once you finished that tiny circuit, is astonishing :) having it hooked up to munin (using digitemp), two DS18S20 are now steadily producing graphs each and every five minutes (the resulting image is published at my blog).",

(It’s 100 years old and huge, so while my focus has been replacing energy-inefficient windows, adding insulation (what’s that?!), I’d like to add some monitoring to the equation.)The only reasons for the Nokia are that I have one and it’s touch screen. There’s no necessity for it to really run the web server or any of the hardware. I have plenty of other machines that run 24/7 that could perform this task.My desire for the N810 is to serve as an interface: it’s small, runs web apps fine, and could easily be wall mounted. I’ve thought about the netbook route, but then I’d have to hack it, rotate screen and add touch capability.I think I’ll pick up some hardware in the next couple of weeks.",

Then just use your favorite serial port capable program on the computer to post the information as often as you like.Now, if you wanted to eliminate the intermediary computer altogether you could use an arduino (or whatever processor) with something like an xport and just make posts to a server.And of course, wiring this to twitter is easy…I recommend “Making Things Talk” by Tom Igoe, he covers a lot of what I wrote…",

For those only now getting into microcontroller projects, the arduino offered a cheaper route than a 70$ or more pic board. Sure, you could build a serial ICP for cheap, if you have a serial port. You could build a USB programmer, if you can program the chip to build it.Once you know what you are doing, you just pull out a digikey/mouser catalog and get a hand full of chips for $20 (or as a sample, even better). 4$ even for a surface mount atmega 168 (aka arduino’s cpu) from . . . can’t tell if this is last year’s digikey catalog or an even older one.",

PIC has cumbersome assembly, no open-source C development tools, generally weaker peripherals, and on and one.

So I did some comparison I openedhttp://www.avrfreaks.net/index.php?module=Freaks%20Devices&func=viewDevandhttp://www.microchipdirect.com/NewProductTree.aspx?mid=14&Catalog=BuyMicrochip&Category=16bitanddsctree&TreeID=8and start comparing one by one similar devises, after I get confused and start wondering why people saying that avr so superior to pics, looking on both websites I saw there is no point to compare atmegas to 16Fxxx family but when you look on 18fxxx family thing getting equal and when you look on 24fxx, dsPIC33 and dsPIC33 there is no point to compare them to atmegas because they clearly win by memory price and speed. So I don’t understand this phenomenon how avrs better if simple comparison show different answer, or you guys compare all avr to 16f84? well 16f84 is not only product microchip make actually microchip deserve respect only for continue producing this ancient chip.Yes there is no free good c compiler for 16fxxx family but there is reason for that how much c code you can fit into 1-4k of memory ? not much useful program.Also I notice in powerful category that there is more pics available in DIP package and only couple atmegas have DIP package and this is serious issue for hobby person.And the last one is Atmel attitude to their product, I remember couple month ago they was selling themselves so do they really care about their chips? Or if something else like flash memory will be more profitable atmell will stop making microchips and start doing flashSo please someone give me good answer, should I consider to swith to avr, point on advantage.Im serious I don’t want war, I want to chose once and improve skills concentrating on one and specific device, just like I chose C++ over java couple years ago after trying both for 2 yearsor all this hassle around Atmel made by funboys? just like around apple.",

RFID
seems to have invaded every part of our lives. Sure, the technology has been primarily used in government and industry, but that doesn’t mean that it doesn’t have consumer applications. Recently, we posted about [max’s]
RFID dorm room lock
, that he built to provide a safe, convenient way to access his room. A while back, we talked about an
RFID spatially aware address book
that used a combination of rfid tags and post-it notes to control the
NFC
enabled Nokia 3220 cell phone. Both of these projects highlight unique applications where RFID is used. We bash on RFID from time to time, mostly due to its security (
or lack there of
). That said, there is an interesting consumer solution out there for people who want to voluntarily use RFID called
Touchatag
(formerly known as Tikitag). The cool thing about Touchatag is that it uses a combination of RFID and QR (2-D barcode) tags to trigger applications on the Touchatag website. The starter kit, which includes 10 tags and a USB RFID reader, goes for about $40; a decent price considering the hacking potential for the RFID reader. In addition to using the reader, you can also use any NFC enabled phone to read the tags. While NFC enabled phones are currently few and far between, the technology will likely be implemented in many of the new phones released in the coming year.
We’re curious, what do you think is next for consumer RFID? What kind of innovative project ideas do you have?

Breath Controlled Guitar Hero Kick Pedal

[Ben Heck] the uber modder has posted a new project. He has made a
breath controlled kick pedal
for all of the Guitar Hero style games. Though the tutorial focuses on Guitar Hero World Tour, he does explain how it could be done for Rock Band at the end. This is intended for someone in a wheelchair who couldn’t actually use the kick pedal and needed their hands free to play the rest of the drums. He took apart the kick pedal that came with it to get the piezoelectric switch out of it. Then, he made a little chamber and placed the switch on a diaphragm at one end. When you blow, the diaphragm moves and triggers the switch. Pretty simple really.
There is a video available
of [Ben] trying it out as well.

The
AVR STK500
has been Atmel’s standard AVR development platform for many years. Recently though, hobbyists have embraced the
Arduino
. [Alessandro] has decided to bring the two together so that you can
use the Arduino environment with the STK500
. Unlike the Arduino, it comes with 8 LEDs, 8 switches, a variable power supply, and variable analog reference. It’s a great way to get hardware you might already have back into service.

[Tom] wrote in to tell us about his JavaScript project for motion detection. It ties together two ideas we’ve talked about recently. The first is doing image processing in-browser using Canvas(), which we’ve seen
employed in captcha breaking
. The second is offloading heavy processing to browsers, which we saw recently in the
MapReduce implementation
. [Tom] is using JavaScript to compare consecutive images to determine if there’s any motion. He did this as part of
MJPG-Streamer
, a program for streaming images from webcams. It can run on very limited hardware, but image processing can be very intensive. Doing the image processing in-browser makes up for this limitation and means that a custom client program doesn’t have to be written. You can
find the code here
and a
PDF about the proof of concept
.

Tools: Saleae Logic, Logic Analyzer

A logic analyzer records bus communications between two chips. If you’ve ever had a problem getting two chips to talk, or wanted to reverse engineer a protocol, a logic analyzer is the tool you need to spy on the bus.
The Logic
is a USB logic analyzer with eight channels and sampling rates up to 24MHz. Among hobby-level logic analyzers, the Logic has a good mix of features and decent sampling rates. We’ve been following Joe Garrison’s work on the Logic for a long time. If you’ve ever considered bringing a product to market, you can learn a lot from
Joe’s blog
that documents his development process.
When it debuted, the Logic was so popular that it was hard to buy one. It’s now widely available, and Saleae gave us one to try. Read our review below.
Logic Analyzers vs. Oscilloscopes
Most modern electronics projects will benefit more from a logic analyzer than an oscilloscope. An oscilloscope displays a graph of an analog voltage as it varies over time, such as the curve of a sine wave. A logic analyzer only detects high and low digital states, but it records many signals simultaneously. Logic analyzers dump data to a computer for analysis, very few oscilloscopes have this feature.
What you get
The Logic comes packaged in an external hard drive case. The analyzer is a small, anodized aluminum puck with laser etched signal markers. It’s much smaller than we expected, slightly smaller than a compact flash storage card. A mini-B USB cable is included.
A heavy-gauge cable and nine
E-Z-Hooks
(5 shown) connect the Logic to a circuit. The hooks are a really nice touch; press the back of the hook to expose a pair of tweezers, grab onto a signal wire, and retract to hold it in place. The retractable tweezers prevent accidental shorts on cramped test circuits.
Software isn’t included, instead you get instructions to
download
the latest version from the Saleae web site. We always download the latest software, so we appreciate that there’s one less CD headed to the landfill.
Right now, only Windows XP/Vista software is available, but Mac and Linux software
should be ready soon
. Warning: the Windows version requires .NET 3.5, download the
redistributable off-line installer
if you don’t want to give internet access to Microsoft’s online installer.
Using it
Using the Logic is simple. Connect the gray ground wire to the ground of the test circuit, then hook into the signal lines you want to record. We connected it to the
32K SPI SRAM
that we demonstrated earlier this week.
SPI
has four important signals; enable, data in, data out, and clock. The E-Z-Hooks make it dead simple to tap into the signals without accidental shorts.
Be mindful of wire orientation. We associate a black wire with ground, but the Logic cable uses gray.
Comments
on SparkFun’s product page suggest that reversing the connections will damage the Logic.
The software analyzes and displays signal captures. The primary configuration options are the sampling rate (200KHz-24MHz) and number of samples (millions to billions). We were able to sample at 24MHz, but the top speed depends on how much other stuff is using the USB bus. A 24MHz sampling rate can capture signals up to 12MHz, we found this suitable for all the protocols we use. The total number of samples is limited only by the available PC RAM.
There’s a four level trigger that watches the signals, and waits for a specific combination before it starts recording samples. Since we’re analyzing SPI, the most logical place to start capturing is when the SPI enable signal drops at the beginning of a bus transaction. We set the Logic trigger to start sampling when SPI enable is 0 by changing its trigger to ‘0’.
We really like the profiles that decode most common serial protocols; 1-Wire, I2C, SPI, and asynchronous serial. CAN and other protocols
will be added eventually
.
Profiles suggest names for each signal, and convert squiggly lines into readable byte values. This is a really awesome feature. Without it, you’d have to count clock pulses to identify byte boundaries, and then manually decode the values.
This transaction shows the host issue the read configuration register command (0x05), and the SRAM response (0x41).
We also tried the 1-Wire decoder with a
DS2431 EEPROM
. The software identified the 1-Wire reset command, and the 1-Wire ‘search rom’ command (0xf0).
A look inside
The Logic is based on the Cypress Semiconductor
CY7C68013A-56PVXC
, an Intel 8052 microcontroller with a USB peripheral. The
8052
is an enhanced version of the well-known
8051
. We can also identify a 24MHz crystal, which is probably multiplied to 48 or 96MHz by an internal
phase-locked loop
.
Conclusion
Logic analyzers take the guess work out of debugging inter-chip communication. If you can’t see what’s going on, the best you can do is guess about the problem. When a project won’t work, 99% of the time we can solve the problem immediately by looking at the signals with a logic analyzer. Without it, there’s no easy way to know what’s happening.
The Logic records 8 channels at 24MHz. The Windows software has useful features, and there’s an SDK if you want to write your own apps. Linux and Mac versions are under development. We really like this logic analyzer, and plan to use it to illustrate future articles.
The Logic is $149 at the
Saleae website
and
SparkFun
, and Joe is working on EU distribution. If you’re interested in the Logic, but aren’t ready to buy, you can
download the software
and try it in demo mode.

"content": "I just got my first logic analyzer from a family member for Christmas (as merely a hobbiest, I couldn’t afford dropping money on one for myself… I just don’t have quite enough need) this past year. I wasn’t involved in the decision-making process (thus the disadvantage of *not* buying for oneself), but the got me a USBee SX series — it’s very similar in form factor to this little baby, and I suspect is approximately similar in specifications. Works pretty well to help debug my PIC projects.http://www.usbee.com/sx.htmlis the one I got, retails at $139 and has very similar looking software. It can also serve as a signal/pulse generator. The software’s honestly a bit buggy, but in fairness I’m running an older version of it in a Windows 7 VM (VMWare Fusion on a Macbook Pro). My old dev machine (*very* old Windows Server 2k3 laptop which gave up the ghost a couple weeks into January) seemed to support higher sample rates (up to the maximum), but 4 million per second is fast enough for what I need, without a doubt.In writing this post, I noticed the fact that I’m running an old version… from the looks of it, the newest version has been well tested in Windows 7, and has more features (like easier-to-read decodes of communications protocols), will have to download the latest to see if I get better performance.But yeah, just an alternative. This looks like the build quality may be a little better, though I don’t see a +voltage output… I use the one on the usbee as a lazy-man’s capture trigger — set the software to watch for a leading edge to trigger a 4 second sample at 4msps, and then just touch a wire to the trigger line and the +5v line — I could just press the mouse, but that’s not always near my circuit.",

Pretty much identical price, but I got small but insanely useful +5 and +3.3V power supplies and a separate trigger and clock pin to boot.The devices are damned near identical, and their software as well. The SPI/I2C capture really is crap though, I can’t use the SPI/I2C clock (I instead have to “poll” the bus, although for I2C I guess it’s more or less a must), and the trigger options are pure shit. I can’t say “trigger on SPI sequence 0xaa 0xbb 0xcc” for instance.The device doesn’t work all that great in a virtualized environment, either, although I suspect that is not the fault of the device. I have asked the Usbee folks for the technical specs so I could write my own linux driver, and I received a very warm response and hopefully will have the data any day now. I want a CLI util that I can use as a function block in my data analysis. :-)Now if I could only find a decent USB 2.0 oscilloscope. I think though, that that’s one realm where I still need a real device, perhaps with a decent USB transfer and control interface. 250MS/sec+, 2+ channels, 600V+ and decent triggering options (say an external trigger that I provide with the logic analyzer?)Anyway. These are very good little devices for hobbyiest or professional use, and I have no problem recommending either of ’em.",

There’s about a zillion products in this price range out there these days.@rasz – you’re close. The 8051 in the cypress part is just a traffic cop. It is not directly involved in anything that limits sample rate. It’s a bit like a DMA transfer. Start it up and get out of the way. As far as the 48mhz clock factor, it isn’t that they have to sample at 2x to get a 24MHz sample rate. It’s that there is enough software overhead both at the pc-side driver level and in their GUI that it’s not possible to get a sustained rate higher than 24mhz. This is quite typical of USB high-speed interface applications. Rarely does any product approach USB 2.0’s advertised 480mbps transfer rate for sustained periods (at least not those using these cypress parts).@ericwertz – if you need to look at 50mhz digital data, then 100Mhz sampling is not nearly enough. Nyquist theory is meaningful for analog analysis, and is a limitation that applies directly to the highest frequency pure sine wave component of the signal – exclusive of phase. Digital analysis is very different. You could barely represent a square wave sampling at Nyquist, and thus would get virtually no timing information from the resulting waveforms. You’ll need to sample 4-10 times your bus rate to get meaningful timing information.@clint – actually their mistake is in *not* having a channel 0. Most logic analyzers do start with channel 0 (or D0), partly because the LSB in digital logic often represents 2 raised to the zero power (e.g. data and address buses). To call the first channel 1 and then use black for it seems incongruent.@andrew – you sound like a real expert. very professional post (in case you are slow, that was sarcasm).",

New Battery For An HP50G

"hp calculator",

] |
According to the author, the HP 50G is an awesome calculator. But as awesome as it is, it is powered off of not-so-awesome AAA batteries. These little batteries don’t last long under the load of the calculators awesomeness, so a
mod needed to be done
. The battery chosen for installation was a replacement battery for a Sony PSP. He was able to find one, including the external charge regulator board for $10. Dropping it into the case and wiring it to charge off of the existing mini USB port looks fairly simple, very few actual modifications are necessary to the body. Unfortunately, they did end up with an LED protruding from the bottom that makes it wobble a bit, but they’re guessing that they get about 2x the battery life now.

Automatic Blind Opener

[Contraptionmaker] ran into a problem when putting plastic insulation over his windows during the winter. When you cover the windows from the inside to prevent drafts, your access to the stick that opens the blinds is cut off. His solution was to build an
automatic blind opener
from a cordless drill. He started with some motors he had around the house, but none of them were strong enough. The final solution was a $10 Black & Decker drill. After removing the handle and trigger to extend it, he made a simple wall mount for it. You may notice him soldering some batteries into it, in his directions. Those are just for backup, in case the power goes out. You can see a video of it in action after the break. If you want something
triggered by an alarm
, or for a
different type of blind
, we may be able to help you out.

"content": "Hi all! My name is ContraptionMaker and I built the blind opener. Thank you all for the comments but I have a couple responses.To qoncept:You could always build a box around it or cover it with a curtain, but this isn’t in my formal living room anyway.To Todd Grigsby:Ya, I could of bought pre-made ones too, but who wants to spend all that money on blinds? Besides that where’s the fun, the mental challange of doing your self? If you read my post athttp://www.instructables.com/id/Automatic_Blind_Opener/you will see I encourage anyone to improve on the idea.To Max:Then why bother with the plastic?To Roamer Iron Lion:I have built two of these and they are both on their second year with no problems at all! My wife does run them to far some times and all they do is make a clicking sound, she stops. they still work just fine.To no one:I agreeTo polymath, DanS, andres, Andy:Thanks!!!",

Can’t say I’ve ever worked with gears other than small plastic toys and bicycles.I think it’d be easy though. Attach a large wheel to the bottom of the stick, and have a belt around that and the motor. I’d have some kind of collar around the stick and make sure everything was mounted sturdily.I’ve been thinking about this one for a while! It would be great to have it on a time so no one can see in your house at night, but it lets light in for the daytime.",
