A couple of readers weren’t too thrilled when
the winners
were announced a while back for the Nokia N900 competition. And to be honest, we even wondered on some ideas (like what does skateboarding have to do with hacking?) However, The teams have been hard at work and a
picture
video is starting to form for each. Check after the break for some video recaps.
[Thanks Matt]
[
Solderin
Skaters
] are up first, they’ve even started
reflowing some test boards

And in a strange twist of events, it seems the N900 will no longer go into orbit. Rather, this piece of hardware will be

360 Degree Video For Next-to-nothing

[Luis], a regular Hackaday reader, sent in some info about his 360 degree video experiments. He wanted a cheap device to use with a video camera, producing video that can be displayed using a free Flash software library.
The hardware consists of a mirrored light bulb, a square of glass, and some threaded rod. The camera lens attaches to the glass with the rod right in the middle. The lens will capture a donut image reflected in the mirror of the bulb. [Luis] then processes the result and uses
Ryubin’s Flash Panorama
to handle playback. He’s posted two clips as examples, the first of an “
Existentialist Suburb Walker
” and the second is
some test footage
while setting up for a shot. You can click-and-rotate the video while it’s playing to look around the area.
This could produce some great driving videos, without
the need for multiple cameras
. [Luis] does point out some problems with oscillation as the mirror on the end of a rod will amplify the effect of movement on the image.

Qube, Not An Arduino Clone

What allows the everyday user to tinker with microcontrollers, IO, interrupts, serial communication, and even analog readings? How about individual modules that add the ability to communicate over bluetooth or add LCD support? If you were thinking Arduino, you would be wrong. It’s actually
[Nilok’s] Qube
, which at first seems like another Arduino clone however the Qube is based on PIC – not AVR. Another difference is the
sweet black anodized case
the Qube is planned to be put in.

seems amazing at first, there is of course a catch – it looks like the first models are pre-order only for staunching price of $70! Sorry, but Arduino wins at
half the cost
.
Regardless, [Nilok] has documented the entire process and it’s amazing to read through; he even includes some guides on
solder paste
and
bootloading USB
. And who knows, maybe he’ll release open source. His site seems a little slow, we recommend the
Google Cache
.

They have a PIC18F4455 and 2 ULN driver chips for 500mA outputs.The theory is that the case should never have to be opened, this is not intended to make it into your final product like the Arduinos have a tendency of doing, this is a development platform to make USB, analog, bluetooth, LCD, PWM, etc SIMPLE. $70 with a slick case is a good price to pay for that IMO.",

[Alexander]
built an RFID emulator
. It uses a wire coil (not pictured here) and an ATmega8 to represent any tag that is EM4001 compliant. This iteration requires connection to a computer to send the tag ID information to the microcontroller. In the video after the break it looks like he’s using a DIY RFID reader to test this. If the two were combined, cutting out the need for a computer, he would have an
RFID spoofer
on his hands.

[over9k] used his Arduino to set up
a laser trip wire
. The laser is mounted along side the Arduino, reflects off of a mirror, and shines on a photoresistor that interfaces via a voltage divider. The signal from the voltage divider is monitored for a change when the laser beam is broken. [over9k] set things up so that a webcam snaps a picture of the intruder and Twitters the event for easy notification. Video after the break walks through each of these steps.
This build is a bit rough around the edges but unlike
other laser trip wires
this keeps all the electronics in one place. The laser interface could be a bit more eloquent, and we’re wondering just how much current it is pulling off of the Arduino pins. But if you’re bored and have this stuff on hand it will be fun to play around with it.

In a recent
blog post
, [Massimo] stated that there will be some stabilizing changes coming for the Arduino platform. The API, IDE, and even the website are targets for the Arduino team’s New Year’s resolutions to bring Arduino to 1.0. This platform is often seen at the core of projects we cover and many that we do not or should not cover. It has come to wide use because it has a better price point to other starter development boards, easy to use with a large user base for support, extensive hardware options with much of the coding already in libraries, and a cross-platform, open source tool-chain that can run just about anywhere. Many people that hate the Arduino, hate it because it is so easy to use. Anyone can get an LED to blink with an Arduino even though there are far more (and far less) elegant solutions. Love it or hate it, Arduino has made a significant impact and the coming changes should help keep it be around for quite some time. Let us look back, how has Arduino affected you?

Just stick some jumper wires in the female headers, hook them up to your breadboard and you’re done. The female headers are the only thing that really annoy me as well though.

At least from my own experience as a beginner. Many of the projects are just testing and experimenting; I don’t want to solder all blinking LED projects and sine wave sound generators.One can just store the sketches in Fritzing or similar to keep a database of projects. In the future I may have something _worth_ building separately and will order specific parts for it. But for learning and experiments you really only need one Arduino and it is cheap in fun.",

It’s like you post the garbage JUST because it uses an Adruino, and that’s just lame.”Or perhaps, just maybe, HAD simply posts all the interesting projects that come across its virtual desk and more and more of those lately just happen to involve the Arduino.Me, I’m thankful for the Arduino. For years, I’ve had great ideas for electronics projects, but could never realize them because wiring and programming microcontrollers was too complicated for me to jump into. References were too obscure and spoke only to those who already knew what they were doing, while the experts were too elitist to bother explaining the basics.With the Arduino, I was able to jump in and accomplish some projects right off the bat. From there, I was able to make sense of things and very quickly learned how to wire my own PIC, how different electronic components work together, how to create proper schematics in Eagle and how to etch my own boards. It would have taken me years of frustration to learn all this if I had been forced to take what the elitists would consider the “proper” route.",

"content": "Well as to the original question “How has Arduino affected you?”…I got a basic stamp a few years back. It was easy enough and I cut my teeth in a beginner way. Last year I wanted to get back into it, but discovered that they went up so much in price that it didn’t make sense at all anymore, so quest for alternatives.Arduino popped up to the top of the list in a hurry.I was an absolute newbie. Arduino is perfect for guys like me. Cheap, easy, expandable and (THE BIG DEAL) very popular. So popular that there are just tons of examples and knowledge pool to pull from. For learning this stuff, there just hasn’t been anything comparable before.Fairly quickly I evolved upward and I now like to use AVR Studio with whatever chip suits the job and just use a breadboard. I still fall back onto the Arduino now & then though, especially if I’m just modifying an existing project. I DO lean toward liking AVR for my own reasons.Guys who know their chit from shinola can pick apart chips and argue one over the other, but usually they get way over my head in a hurry. My opinion: I could care less. For me Arduino was an easy way to get the job done, and I didn’t have to spend 2 years learning every little peripheral factoid in general electronics to pull off a project. I start with Arduino (or maybe some other AVR chip & breadboard) and learn the needed factoids as I go along to so I can get something working.Here’s the deal:Arduino has pulled a mass of people into the field who would have otherwise lost interest. This mass of people helps each other to learn micros and what they can do with them.It’s too easy? Great! Now I have time to learn about electronics AND build things that work, all at the same time. I’ve learned a ton over the past year or two. No way I would have gone so far if I had to make my own transistors from mining pebbles I find in the yard first. I’m working my way up to “real” hacker. In the meantime, I don’t understand why anyone feels the need to beat us newbies down before we reach that point, if I ever do. (well I DO understand why, but getting ahead only by tearing others down isn’t exactly something I subscribe to).It seems simple to me. Arduino is very popular, so HAD likely runs across tons of folks putting ideas to use with them as the core. It’s not like the seek out Arduino projects just to annoy the audience. I can see how veterans can get tired of seeing what they perceive as “the same old thing” re-hashed. I know there is a lot of stuff I thought I’d like forever when I was young, only to find that I’m sick of most of it now in middle age. I suspect that if there was no Arduino, the veteran hackers would still find the published subject matter to be a little more familiar than they would like. It’s just the way of things. I hope there is still enough of non-Arduino stuff here for them to enjoy.As for me, I really enjoy about 80% of it. That’s pretty dang good.",

There is too much hardware that you read the datasheet twice, then implement, and it doesn’t quite work (most recently an I2C display with a weak pulldown capability, and the Sparkfun HMC breakout that needs you to add a capacitor, and in the case of mine, reflow). I can verify everything and get it working using a sketch in the environment, then move to a makefile using the libraries, and descend to pure embedded.The wonderful if you do say so yourself captive C-in-IDE that only works in Windows (I have Mac and Linux and only boot windows to update things every few months) means I will NOT use the product.I stopped doing hardware for a while (the 68HC11 was the last thing I used because I could find similar boards to the Arduino – inexpensive, bootloadable, but they disappeared). I got a Make magazine device, but never really used it – it did have GCC, but the ICP pin wasn’t brought out to a connector.The arduino doesn’t have such limitations (With one annoyance with the Mega that some ICP pins aren’t connected, so my pulserial has only 2 channels). Like the PC, it is open enough so you can make of it whatever you want. It is inexpensive, so I can get 5 boards for $100 and blow one up without declaring bankruptcy. And they have all the flavors – lilypad, mega, pro…I now have an AVR Dragon (mainy for HVSP/dW for ATtinys), but the arduino is just so easy to use.",

The reason it is an oxymoron to assign preppy names (although it is prepatory) is because if it was better than it wouldn’t be regarded as beginner.Is it possible to begin on a platform that will offer you more and allow you to grow? Is it possible that spending money on a beginner kit with limited capabilities means that you could have got more value if you bought something that has been around for a while and is more middle of the road?I’m sure that a lot of microcontrollers do the same thing and I don’t have anything bad to say about any of the microcontrollers.

My own problem is with all these PIC’s applied to really trivial functions (e.g. using an Arduino where a 555 would be the better choice).There is an obvious imbalance between fancy software driving braindead hardware. Trying to do “electronics” entirely in software is like trying to swim without getting wet.

With more experience the problem is first examined to see what the best approach might be. With maturity you stop looking for things to do with your favorite, and start considering the best *overall* way to control the washing machine, Jumbo flight controls, or whatever.Sure experience often looks like eliteism or snobbery to the newby, but who is the real snob, someone who sees their favorite as all things to all men, or someone who sees it as just one of a very rich selection of possibilities?",

I think learning and so education will happen in more dimensions and the linear form of learning from basic to expertknowledge will change. I am often amazed to see how young people try to manage tasks in computer programming. They often have never heard from an ALU OSI layer etc. but solve problems in a really good way. When I talk with them a few years ago , and they are still in programming they know all these things and more.

Did you make sure that during the process, you actually gained some insight into what’s happening, so you can break out of the ‘lazy-mans’ way of doing it and apply those things you learned to something new.Cheers.",

[Jerry] retrofitted a
Supermax Mill
that he purchased from a friend. The main problem consisted of the original controller failing so he used some Pixie boards and a PC to get the system
back up and running
.
But thats not all. [Jerry] also retrofitted his
Monarch lathe
(yes, not a CNC, but are you really going to complain) by replacing the original
Ward-Leanard
motor generator with a 2 kW brushless AC servo.
The Harford HackerSpace group claims
their CNC
can kick any other CNC’s butt! Currently it lifts up to 65 pounds, but is still accurate enough to make ninja throwing stars. The only problem left is naming their CNC, any suggestions?
[Ciric] has finished up the hardware side of
his CNC project
. However the software is still being worked on, but because it is his own stepper control board it might take a while. The good news is the controller and software are planned to be released free.

Lightning Rod: Keeps You Safe From Dirty Flashers

A new
open source package called Lightning Rod
will help to close security exploits in Adobe’s dirty Flash code. A presentation made at the
26th Chaos Communication Congress
showed that the package does its job by reviewing incoming code before the browser executes it.
Heise Online is reporting
that this method can block over 20 different known attacks and can even be used to filter out
malicious JPG
attacks. As more vulnerabilities are discovered they can be added to Lightning Rod to close the breach. This amounts to a virus scanner for Flash code. It’s great to have this type of protection but why can’t Adobe handle its security problems?

FPGA Keyboard Synthesizer

This synthesizer
relies solely on an FPGA for key detection and sound synthesis. [Chris] and [Joe] built it for their final project at Cornell. The hardware implementation includes velocity sensing for the keys. While at rest, each key contacts a strip of copper foil. A matching strip of foil contacts the key when it is depressed. The velocity data is extrapolated by detecting when a key leaves the rest state and arrives at the depressed state. Sound synthesis is handled in hardware using the
Karplus-Strong string synthesis
method. If you want to hear what it sounds like, they’ve
posted a video
(MP4) that shows off the creation. It sounds like an electric piano to us, so mission accomplished.

[Swake] tipped us off about
a collection of old equipment
. The site is packed full of various hardware that was used for electrical and chemical testing, metering, and experimentation. You could use this to identify the dinosaurs found in backrooms of college science departments, or draw inspiration from it. The next time you’re laying out a panel, or working on a steampunk-ish project go to the source to achieve that vintage look. Some of these remind us of the control panel on
[Steve Roberts’] bicycle
.

It’s all fine and dandy to have a turntable that sounds great, but [Mike] wanted one that looks great too.
He build the transparent record player
above and loved it for a little while. When his interest in it waned he built another, then several more. They all have some element of transparency to them, and each is a work of art. Makes us wonder how often he needs to dust his house to keep them looking so good.
Is turntable technology too advanced for your tastes? You can stick with your
Edison cylinder
, we won’t make fun.
[Thanks John]

[Rp181] is at it again with version 2 of his
rail gun project
(link dead, try
Internet Archive
).
The original
did have some power with 18 400V 3900uf capacitors, but he’s ramped it up to now using 40! Reaching more than double the amount of joules of energy, 12kJ vs. the 5.6kJ! Some other changes include a new injector solenoid setup and revision 3 of his
breakwire chronograph
. Sadly, he doesn’t mention if this is as green as his first rail gun. Check out a video of just the injector firing and an animation explaining some new updates after the jump.

. The Nspire thread linked above discusses the DMCA concerns just a bit but it seems obvious to us that running your own code falls under the umbrella of the act. The exploit package hasn’t yet been posted, but if you want it make sure you check back regularly before the take-down order comes in from TI.

Trailer Side Indicator Lights

[Imsolidstate] is working to
add side turn signals to a trailer
. These orange clearance lights are illuminated when the vehicle’s headlights are on to increase a long trailer’s visibility. They also blink along with the turn signals on the back of the trailer. A standard 6-pin lighting harness doesn’t support this functionality so the trick is to add them without altering the towing vehicle in any way. He’s using an ATtiny24 microprocessor to interpret the logic from the vehicle and then translate the turn signal and tail light data into a signal for the additional side indicators.

So when you are driving down the road both of your turn signals come on when you put on the brakes. And big rigs have dedicated turns signals that are independent of the brake signals.

The necessary logic could be done with just an AND circuit wired to the brake/turn bulb wires. If both bulbs are on, the output goes high and energizes a relay coil. Then you just wire the side indicators through the normally-closed contacts, so they’re inhibited from lighting up whenever the relay energizes.I kind of feel like people who got into electronics after the debut of microcontrollers go straight there because they don’t know any other way to do it.",

Yet when safety is the *first* priority, it is advisable to also be cognicant of reliability issues.

In other words, eliminate as many potential points of failure as possible.I cringe when I see a micro in an application like this, and not just because it’s perhaps overkill. Take this from someone who *must* always consider liability issues, i.e. Elec.

Not to mention on/off brake activity while the signal is flashing makes the side signal flash erratically. That’s why micros are better, I only need one chip to do this and I can reprogram it whenever I want to make changes. Do that with logic gates.JDN: it’s a prototype. Calm down.BCK: read my article.

Meat Smoker From 55gal Drums

[Joel] wanted to use his newly acquired welding skills to make something useful. With tasty flesh in mind he put together this
meat smoker
. What resulted is incredible, but the fact that he then gave it away as a gift is just amazing.
A curved joint between two pipes is known as a ‘fish mouth’. They can be a hassle, as with
the pirate wheel
project, but [Joel] used his noggin to make things easier. He first modeled two 55 gallon drums in CAD. The intersecting curve was then generated by the software, printed out on paper, and stenciled on the drum to be cut out with a jigsaw.
[Joel’s] writeup is greatly detailed and shares many pictures. He makes every part of this smoker, including the wood handles and the stainless steel grates. The guy really knows how to build stuff, but we should have known that after seeing the
Crushtoberfest
.

Add wireless and you free yourself from sitting and watching the beast – as anyone familiar with home smoking knows about. Could probly get away with thermistors up top (polder probes for the meat) but would want type k thermocouples below where the real heat is.Makes me want to go fire up the Big Green Egg!",

You know it’s getting a bit ridiculous when hardware that hasn’t hit the streets is being rooted. That’s exactly what has happened, root access can now be achieved on the Nexus One. [Paul]
found an exploit and packaged it
nicely so that anyone can do it. We do wish he had shared the details of the exploit but we’re not complaining.
If you’re not in the know, the Nexus One is the fabled Google Phone now come to life. It’s slated for release in 2010 and
some think
that will be officially unveiled at a January 5th press conference. That’s right,
unveiled
. The device has been cracked yet it doesn’t officially exist. What it does do is join a
growing number
of
rooted android
phones.

Practically speaking, rooting can enable things like 3G tethering; and more ostensibly, editing files in the phone’s root filesystem.The real-world uses for a rooted phone are pretty few for the average user, but some people want full control over their handset.

When we introduced you to the
Twitter Christmas tree ornaments
, sadly we had very little information about the project. Luckily [Rob] made contact and clued us in on the inner workings. It even turns out we were wrong about the usage of Arduinos! We invite you to check out all the juicy inner workings after the break.
Lets jump right into the explanation,
So the controller uses a single Arduino connected to 3 74HCT595 shift registers. The ‘595 takes a clock bit and a data bit, and each leading edge (0-1 transition) of the clock bit shifts in a data bit. Then there’s an 8-bot latch, and the leading edge of another line captures the state of the shift register to the outputs. Each ‘595 stores 8 bits, can be chained, and there are three of them. This lets it control 24 lights with only 3 I/O lines. Each output is connected to a TIP31 transistor, in standard NPN configuration. The TIP31 can switch up to 3A, so they handle the 1A 6V lamps with no problem. This is pretty close to the schematic we’re using, except only 24 outputs:
Here’s the sketch I used to control the shift registers:
long count;
unsigned long val;
void setup()
{
Serial.begin(9600);
pinMode(10, OUTPUT);
pinMode(11, OUTPUT);
pinMode(12, OUTPUT);
pinMode(13, OUTPUT);
digitalWrite(10, HIGH);
digitalWrite(11, LOW);
digitalWrite(12, LOW);
digitalWrite(13, LOW);
count = 0x00;
val = 0;
}
void loop()
{
unsigned long i;
if (Serial.available())
{
char c = Serial.read();
if (c >= '0' && c <= '9') {
val = val * 10 + (c - '0');
Serial.print(c);
} else if (c == '\n')
{
Serial.print("setting count to ");
Serial.println(val);
count = val;
val = 0;
}
}
unsigned long bv;
digitalWrite(10, LOW);
for (i=0, bv=1; i < 24; ++i, bv <<= 1)
{
byte bitval = LOW;
if (count & bv)
bitval = HIGH;
//Serial.print("i ");
//Serial.print(i);
//Serial.print(" bit ");
//Serial.println((int)bitval);
digitalWrite(11, bitval);
digitalWrite(13, HIGH);
delayMicroseconds(50);
digitalWrite(13, LOW);
delayMicroseconds(50);
}
digitalWrite(10, HIGH);
delay(10);
//++count;
//count &= 0x3ff;
}
I bit-banged the SPI protocol, since I was having trouble using the hardware SPI, and figured it was easier than fiddling with registers. I since discovered the breadboard was a bit flaky, and lowering the bit rate would have probably worked too, but that’s for V2.0 :-) It listens for a number on the serial port, and shifts that number into the 74595’s. Lather, rinse, repeat.
The other side is an old netbook, running a Processing sketch – since I didn’t write it, and forgot to ask for permission, I can’t attach it, but the essence is a loop that screen-scrapes Twitter’s search API, and sets the bits of a long corresponding to the words that it finds. I’m now updating it to blink faster or slower based on the frequency that a word occurs, since words like Christmas seem to appear frequently this time of year, who knew?

There you have it. For those wondering, the schematic is actually for an upcoming light control shield [Rob] is working on. You can expect to get your own around April. For those that just can’t get enough
Alpha One Labs
goodness, be sure to join us for
their regular UStream
this evening at 7pm EST.

that walk through the progress. In addition to seeing the intricate ramps, traps, and controllers she outlines her build techniques. These include reproducing parts based on old pinball machines and bending acrylic with
a custom tool
or a
toaster oven
.
The driver she’s planning to use is an Altera FPGA with a bunch of FETs to control the heavy-load components. There’s not a ton of info on the actual electronics but we had a heck of a fun time looking at the creative field components. Our favorite by far is the
television from Day 7
. The screen is translucent with a rear projected image. When the ramp in front of it is raised the pinball can be jumped right through the screen!
We couldn’t find a project page for this but we’ve embedded [Jeri’s] videos after the break.

CoffeeScript: Like Aspirin For JavaScript

CoffeeScript
is a language that compiles down into JavaScript. “But why? JavaScript is so simple?” Bullcorn.
If you don’t use JavaScript everyday the language is wonky and frustrating. When you need quick snippet of Javascript to build into a page you may know how to do it with three or four different languages but struggle with the touchy syntax that has long given developers headaches.
Give CoffeeScript a
try
, you’ll like it. If you do,
give them a hand with development
too.

Having to load an entirely new stylesheet dynamically is a tad irritating.As for JQuery, I know a tad and have actually been looking into learning more recently. I love how versatile JQuery is when it comes to finding the right part of a page you want to change. With JavaScript, finding a particular part of a page can be done easily with .split() and such, but once you’ve used methods like split, you can no longer change its value dynamically. JQuery remedies these flaws quite nicely. Visual effects like fadeout are nice too. :D",

[Kyle McDonald] has kept himself busy working on 3D scanning in realtime. He’s posted a writeup that takes us through the concepts, tools, and assembly of a
DIY 3d scanning camera
. You should remember
a preview of this method
posted earlier this month, but now it’s time to build your own. You’ll need a camera, a projector, and
some open source
software to process the image data. Using these simple tools, [Kyle] turned out much better video than
before
. Take a look after the break to see his results from scanning at 60 fps using a PS3 Eye. The trick to this setup is getting the correct synchronization between the projector and the camera, something that could be improved with a bit of extra hacking.
Does [Kyle’s] name sound familiar? It should, he’s got a long history of quality hacks that we’ve featured over the years. If you’re looking to use a
scanner as a multitouch
, add some
music to tea time
, or
play with your skittles
his work will give you a shove in the right direction.

RFID Meets Open Sound Control

Have you been working on a MIDI controller that uses RFID to identify and control different instruments? No? Neither have we but now we’re going to have to look into it. That’s because [Martin.K] has done a lot of the work for us. His
nfOSC package
links an RFID reader to the
Open Sound Control library
.
In the video after the break we see [Martin] placing RFID tags onto a
Touchatag
reader. With each addition, his software triggers a tag add event that OSC picks up and translates to a midi event; in this case it adds a new instrument to the mix. Can this be used to relieve musicians from staring at computer screens during performances? What if there was a small shelf in front of you? As you happily play your
electric Didgeridoo
, small items with RFID tags on them can be added or removed from that shelf to change the samples that are triggered when toiling away on that sonic weapon. This should be fun!

After getting some fun new toys for Christmas, [IceColdFreezie]
set up this kill counter
for
Team Fortress 2
. At first glance, we weren’t that impressed. It’s an Arduino and a few LEDs. Then we saw that it was counting the kills in binary. We’re not sure if it gets much geekier than that. You can download the source code and try it out yourself. Just don’t make more than 31 kills.

This is sent to the Arduino every time it changes, and is converted to binary and displayed on the LEDs (I don’t have a 7 segment display)As I said in the video description, its nothing too spectacular or useful.Also, @poot: Could you explain how that would work?

[Brett] posted about
his most useless machine
build. His project gives us a chance to massacre the language in the title because it uses the lowest parts count we’ve see with
these machines
. The logic is controlled by our friend, the 555 timer. Add to that just one servo motor, two switches, three resistors, two caps, a diode, and a battery pack and you’re in business. The hardest part to find locally is the servo but check at a hobby/RC store. If you don’t have to put in a parts order this can be your next impulse project.

My main goal however was to have the machine REALLY turn itself off.The machine in THIS instructable accomplishes that!” –http://www.instructables.com/id/The-Most-Useless-Machine/So there is a difference….just…not much of one.This is neat though, I’ve been thinking of building one to sit on my desk but it would distract me from work quite a lot.:P",

I’m not sure your schematic makes that clear.Gearboxes though are a pain to source if you want a new one, its best to rip up an old RC toy but then you usually end up with a gearbox of arbitrary ratio.Its so difficult to source the perfect gearbox without making your own gears and shafts on both a CNC mill and lathe, or something. And if you do find one, its for industry, and costs a small fortune.And therein lies some advantages of a servo and microcontroller because you can control the speeds yourself!Great little project, the wooden box helps a lot because if you hadn’t seen one before, like I hadn’t, its all that more amusing! :-)I’m seriously thinking of adding that one to my list of stuff to make, but it would get very boring very quickly unfortunately.",

An unemployed electrical engineer can be a very dangerous thing. [Cybrown] has turned his skills toward darker, more awesome applications by
building an armed unmanned aerial vehicle
. This is a remote control airplane that has a movable camera mounted in the cockpit. Video and GPS data are sent back to the pilot who views the picture via a
wearable display
. We’re betting this doesn’t have the range that the
100km UAV
did, but that’s good because this one brings doom from the skies. Check the wings in the picture above, this RC is fireworks-enable. We’ve embedded flight footage and attack video after the break.
Update:
Here is
a forum post
covering this nugget of awesome. There are just
a few details
but the entire thread is interesting. Someone pointed this out in the comments but they don’t get credit because they didn’t leave a link.

My (then young) grandfather worked on such projects during the all-too-brief period that the official goals of our governments did not align so perfectly.Luckily, we no longer have to argue about such differences. And we were so similar in our natures, wasting time arguing about trivial issues such as religion and foreign policy!They used UHF(!) television cameras on pulse-jet flying machines, guiding them by remote control. It did not work very well, and did not have good range, but it did work. How far we have come!Only a few were made and tested, and then… quite suddenly, the party was over. The V2 got all the attention, even though it was much more expensive to make in terms of cost per kilo per kilometer. This is a lucky thing, because these men made it possible for us to punch holes in things that used to be too far away to really bother with, like the moon and caves in the khyber pass.I do not understand why @Twerpling asks about banning, such items are already banned; it is just that the laws are not very well known or publicized yet.My father gave me a replica flying wing glider kit from brazil, which I suppose could be used like this very easily. I haven’t put it together yet, mostly because I have been playing with Klaus’s WII every night since Christmas.",

discusses their work and provides
slides

Location Tracking Using IR Throwies
|

[
"LED Hacks"
] |

"augmented reality",
"infrared",
"ir",
"ping-pong. Styrofoam",
"throwies"
] |
[Joe] and his team hacked together some
location tracking using IR throwies
for their final project. The challenge they undertook was to find a way to track the orientation of
a sculpture
in the form of a rotating metal cube. The end result dips its toe into the augmented reality pool but the methods are what interest us.
They wanted this to work day or night so contrast would be a major issue if working completely with image manipulation. Having a simple way to pick out the corners of the monotone block would make this process a breeze. They ended up using magnetic
throwies
that have an infrared LED which can easily be picked up by a webcam no matter what the ambient light issues happen to be.
After the break you can see these guys out in the wild testing the system. We’d like to note the diffusers used in the project. We’re used to seeing
ping-pong balls as diffusers
but this is the first time we’ve noticed Styrofoam balls being used.

PS3 Wireless Visual Interface

[Technott’s] at it again, this time
extending the Playstation 3 with a wireless interface
. This handheld isn’t actually a PS3. It provides a wireless connection to your PS3 to receive audio and video, as well as to manage controller data. Think of it as a wirelessly tethered handheld that allows you to play Playstation when your wife is watching the Real Housewives. This is similar in size to
his Xbox 360 WVI
but the case shape and appearance are a big step up (not that we disliked that one). We’ve embedded a video tour of the device after the break.

Panoramic Scanner Camera

[Photodesaster] put together a
panoramic digital camera using a scanner
and some miscellaneous parts. You may remember
seeing something like this
about six months ago and
originally
about five years back. The
parts used here
work together nicely. The sensor board from the scanner is mounted to a metal plate along with a 50mm lens. The plate is mounted to a hard drive platter that is turned via belts connected to the original scanner motor. This way, when you tell the computer to scan an image, the lens is rotated to capture the panorama. The use of an 18V tool battery is a nice portability hack for the scanner circuitry.
Judging from this
71MP image
he has achieved some remarkable results.
[Thanks Stefan]

I don’t perform a per-pixel white calibration as a normal scanner does, but I have a few ideas how to reduce the effect by post-processing.There are two darker bands visible in nearly all images, I think that I damaged the sensor during my first experiments by rotating the lens towards the sun without IR filter.There are lots of reasons for loss of details. Apart from the things you mentioned, there is the less-than-perfect IR-cut filter, vibrations in the mechanics (partially excited by the stepper motor), the three color components for each pixel being captured sequentially (different lens position and time) and the sensor’s active area being less than 40mm high.I could not find a datasheet for my sensor, but other 1200 DPI sensors have odd and even pixels for one color in different lines. This could also be a problem.Can you post a link to a quality scanned full resolution picture taken by a 6×9 of 6×17 camera for comparison?I was already happy to see dark pixels next to bright pixels at full resolution. I didn’t really expect this.And always keep in mind: this is just for fun, it didn’t cost me anything and is IMHO no serious alternative to a large format camera or a panorama rig creating stitched pictures.Nevertheless it’s tempting to get hold of an old 3200 DPI scanner, some medium format lens and to try it again in the Gigapixel range…",

Ikea Dioder Hack

"LED Hacks"

"ambilight",
"ikea",
"led"
] |
[Joseph] wrote in to tell us about his
Ikea Dioder hack
. The
Dioder
is a lighting system with a silly name from Ikea. It is basically 4 RGB LED bars that are connected to a controller that will cycle their colors in different manners. They aren’t individually addressable, and at $50 aren’t really that great of a deal for people who could build their own. [Joseph] thought that maybe, if the features could be extended, it could be a decent lighting system. He bought it and began searching. Disappointed by the lack of hacks available, he cracked it open and began brainstorming. Ultimately, he decided to interface it with his computer. He can now control it with software, so making an
ambilight clone
shouldn’t be too difficult.
He does mention that he thought of making 4 independent drivers so that each light bar could be a different color. We agree that this would be the next logical step, possibly even rewiring for individual access to each LED.

Composite Video Output From Chumby

"composite"
] |
[bunnie] posted this pretty slick way of
getting composite video out of a Chumby
. The
Chumby
is an open source connectivity device that has
already seen some decent hacking
. This modification, done by [xobs] isn’t too difficult. It only requires patching into some pads on the motherboard and loading a custom kernel to support the external output.

We asked for CNC projects, and wow did you guys deliver!
First up is [J-J Shortcut’s]
MDF based CNC
. He’s made three thus far, with the most recent costing about 180 euro and taking 2 months to build.
[Qwindelzorf] has also constructed a multitude of CNC machines including this
industrial size router
and this
smaller miller
.
Finally, [Mick’s]
large steel CNC
which just made its first cut only a week ago!
Keep up the great work guys, CNC machines are not easy to build and your accomplishments are ones for the record books.

Hackaday is going to the
2010 Consumer Electronics Show
in Las Vegas. This year’s show runs January 7-10 and we’re going to use every minute to scout out hacking’s past and future. We’re looking for hacks from the past that have made it into new,
commercially available electronics
. We also want to get a look at the products that we’ll all be cracking open at some point in the future.
Do you know of something being exhibited that we shouldn’t miss? Tell us what to look out for in the comments.

This art installation
uses buttons made of light. A projector fills up the walls and ceiling of a room while a webcam monitors the pattern for changes. When the luminosity of a given area changes due to a shadow, a midi event is triggered. The software that controls the system is written in C# and uses the
Emgu CV library
to handle the image processing. In the video after the break you can see that creating shadows with your hands prompts changes in the image as well as the sound.

[Lee] wanted an electric Melodeon to use with his band. A Melodeon is a chromatic accordion and there are people who already make electric versions but they are a little too expensive for him. Instead, he bought a toy accordion and
added electronics to it
.
After being thwarted by forgotten PIC skills of yore, he went with an Arduino as the controller. Two pressure sensors are used to detect the squeezing and pulling of the instrument’s bellows. His did some solid work. The video above uses 8-bit sounds
like we’re used to from video games
and the one after the break sources more traditional accordion sounds.

[Infernoz]
built a POV display
to help ring in the new year. There is a low component count; an ATtiny26, DIP switch, power switch, CR2032 battery and holder, pin header, 8 LEDs, and a pull-up resistor. The board is single sided without any jumpers that we can see. He’s moving the display by swinging it on a rope but the PCB is the perfect shape to
attach to a fan
. We love these
blinky displays
and if you’ve got some parts this makes a great party favor for New Year’s Eve. Check out the video after the break.

Lightdrawing Robot

Long exposure “light drawing” photography has become pretty popular lately. We see images pop up all the time that look pretty cool. [Nils] wasn’t feeling particularly artistic himself, so he
made a robot to do the hard work for him
. he can program patterns in, and it will replay them by changing the color of the light on top while it drives around. Though it may lack a little of the fluidity of the hand made images, it can probably make up for it with complexity. This isn’t the first time we’ve seen this
style of photography mixed with robotics
, though this one seems fairly more flexible. Tune in after the break to see a video of it in action.

Industrial CNC Controller Retrofit

[Jerry] had a beefy CNC lathe whose controller wouldn’t respond. He cracked open the case and found a large scorch mark surrounding one of the servo controllers. Rather than just replace the IC and still be stuck with a 23-year-old controller he decided to
retrofit the machine with modern controls
.
The journey from a brick of steel to an incredible machine is fascinating. Using a combination of commercially available boards like the
ModIO controller
and custom-built circuits, he cleaned up control signals and give life to the lights on the original faceplate. The machine is now
working beautifully
with a new monitor, automatic oiling, and wireless connectivity.

You can try to be unimpressed. You can attempt to feign disinterest. But even the most casual Star Trek fan will get giddy watching this
model submarine in action
. Apparently there is a group that builds under water R/C vehicles from static models.
It’s not Star Trek exclusively either
, we saw some anime vehicles as well as a modern-day shuttle replica.

Five Updates For The Steadicam

[YB2Normal] has
updated his steadicam 5 times
! For those that remember
the original
, it allowed indie film makers to create smooth and steady video.
Version 2
implemented a new gimbal based on a throttle linkage in cars.
Version 3
allowed the user to easily adjust angles and weights to prevent accidentally knocking the assembly. Version 4 seems to have disappeared. And finally,
version 5
updates the gimbal again using a Traxxas U-joint and redistributes the weight. What should come next? We think a handle, holding onto a threaded bolt can’t be good for your hands.
[Thanks Update]

XeXLoader Reminds Us Of Xbox Glory Days
|

[
"Xbox Hacks"

[
"xbox",
"xbox360",
"xexloader"
] |
The
newest version of XeXLoader
boasts a pretty slick GUI. This is a homebrew loader for the Xbox 360. Don’t get your hopes up, it requires an older kernel and
you’re not getting on Xbox Live
if you do this hack.
But think back to when the original
Xbox was first hacked
. Watching the XeXLoader (after the break) sends us back to the days of
EvolutionX
. Sure there wasn’t much that could be done in those early days (other than pirate games), but that slowly changed with the hard work of a lot of developers.
XBMC
came out of those first steps and became the
greatest media software ever
to grace your television. The GUI work here may be more beginning steps in another great community-driven legacy.

ATmega8 Spectrum Analyzer

"charcter display",
"hd44780",
"lm324",
"op-amp",
"spectrum analyser"
] |
[Manekinen] built a very responsive
spectrum analyzer
. The components at the party are what you’d expect, an ATmega8 does the hard work interpreting data from the LM324 op-amp. This build stands out because it is fast and configurable. In fact, the explanation of the calibration process is where this project shines.
Instead of
using water
, an HD44780 module displays the spectrum data. The device currently supports several different character displays including 16×2, 20×2, 24×2, and 20×2. We’ve embedded a video of a 20×4 VFD in action after the break. As the video progresses, watch for the Polish words that pop up. This corresponds to the brightness and sensitivity being adjusted with the 5-button keyboard.

If you didn’t get the geeky watch you wanted for Christmas you should consider building yourself a
MakerBotWatch
. The watch is an Arduino, using an ATmega328 microcontroller running the bootloader. The watch has two concentric circles of LEDs for minutes and hours. A vertical row of four LEDs adds in the additional resolution needed to get 60 minutes on the watch face.
The schematic and board layout are available from an
SVN repository
so you can make your own board. The device will go into production as a kit but currently the laser-cut bezel will not be part of it.

One, because I already know C and its a lot easier for me to think in that way, and two, because i heard there are problems with the arduino libs and interrupts.My plan to make it more viable as a wristwatch is to use a 32.768khz crystal, and go to sleep in the in-between time.All of a sudden, this becomes a hackable, hacked platform wristwatch.

Now you can have a Zilog computer in the form factor of a matchbox.
The RamBlade
is a tiny PCB that uses a Parallax Propeller IC to implement the
CP/M language
. The OS is stored on a microSD card, with a four-pin serial interface (3V3, GND, SO, SI) that allows operation via a terminal program.
Smaller and more resilient than
building your own from ancient logic chips
, we see this a way to get a whole new set of people interested in this old technology.

[Jared] had a bunch of lasers left over from a previous project that he put to use by
producing this laser harp
. The look of it reminds us of a very small
Koto
or perhaps an
Autoharp
(although the chords can’t be changed on this model).
We’re so glad that [Jared] spent the time to produce such a fine looking body for the instrument. The strings that would traditionally produce the sound on a harp have been replaced with laser diodes shining at Cadmium Sulfide photo resistors. When a beam of light is broken, an Arduino detects the change via the CdS cell and plays a sound through an Altec Lansing speaker inside of the case.
Unfortunately there’s no video available but we’re pretty sure it makes a “pew-pew” sound. There is a link to download the source code but it points to the overview page instead of downloadable code. From the
fritzing
diagram the CdS cells are part of a voltage divider which provides digital logic to the Arduino. That should be pretty easy to replicate even without seeing [Jared’s] code and we’re sure you can source other Arduino instrument projects for tips on
wave shield
or
midi functionality
.

Thanks to [Josh, Kyle, and Mike], it is now possible to wage (Nerf) war with an Arduino.
The turret designed
around it is capable of shooting
6 foam projectiles
in close succession, between reloads. The faux weapon interfaces with a computer through the Arduino’s
onboard serial link
(via USB). Software on the PC sends commands to the Arduino, which then executes functions, such as panning, tilting, firing, and rotating the cylinder. The power for the firing itself comes from a 5 gal, 80 psi air compressor.
The Java
software on the host PC also does smarter things, like show streaming video from the turret’s webcam and even performs basic object tracking (with mixed success). All the code for building the brute is available on [Josh’s] website.

…well not quite, but Victorian-styled nonetheless.
In the same vein as
his previous creation
, [Jake] decided to steampunk his new monitor. However,
this time around
, he managed to squeeze a full pc into the retro case. A custom aluminum chassis had to be designed and safely house the disk drives and motherboard behind the monitor. Since the 350W PSU was a bit too clunky to mount behind the screen, [Jake] rebuilt the base of the unit around it. The P4, 250GB SATA hard drive, and gold painted cooling fan allow the machine to run
Kubuntu “Gusty Gibbon”
smoothly. Coupled
with a typewriter-inspired keyboard

wasn’t satisfied
with
current methods
for duplicating
Philips Ambilight
. He wanted a completely plug and play solution without soldering so he could expand upon it in the future. This meant Arduino, ShiftBright, and (it pains us to say this) pre-made cables. Some of you are cringing at the thought of no real ‘work’ being necessary, but remember, now this is much easier for your “I can’t change the VCRs clock” aunt to set up and enjoy. Plus it’s quick, easy, and most importantly – clean, something a lot of hackers
have a problem with

But i really would like to use it with XBMC (http://www.xbmc.org), sadly there is no good solution which can interface with atmolight. The creator of boblightd started a branch couple of months ago, in which he implemented it into XBMC. Sadly the last changes to the code were 3-4 months ago and it’s still not public, but a video on his youtube channel looked promisinghttp://www.youtube.com/watch?v=_ZfodqE6daw).When it will be supported in XBMC i think i will switch to boblightd, which can drive much more channels and the arduino code i quickly changed.",

We’ve seen the Arduino board in charge of some pretty unique tasks in the past. Harvesting locally grown soybeans was not one of them.
[Lance]
rigged this beast up
in order to automate the monotonous task of driving up and down the vast soybean fields of Iowa. The 15 ton farm combine’s hydraulic steering pump is at the mercy of a team of gadgets, including a GPS,
Windows 7 PC
, and the omnipresent Duemilanove (which acts as the output card, connecting the PC to the pump). So far, it is reported to be doing a great job, straying only about an inch and a half from its desired, GPS-programmed, path. Even if the Arduino decides to go totally berserk and drive the combine off course, speeding around at 5mph makes it pretty avoidable. A supervisor is also in the cabin at all times, looking out for errors. [Lance] eventually hopes to offload all steering-related calculations to
the ATmega328P onboard
.
Commenters are welcome to share heavier-duty uses for the Arduino (if they exist).

Might not sound like a lot, but when you have 5 miles of crop to harvest one pass at a time, that smaller overlap can save you a lot of trips.",

Given that towns are normally 10-20 miles apart, I am close enough to be able to choose between 3-4 RTK base stations per field. All I do is input a code, which I’ve never had to pay for because the base stations are either owned by the local John Deere stores who many do business with, or friends that put up base stations themselves.And, there are enormous benefits to using precision farming techniques like this, although I agree auto-steer doesn’t do much other than free up hands. One example is that you can plot and save yield maps and compare these yield maps to the variety of crop planted in the spring and the type of fertilizer used, etc.",

[Willem] has been using an
Arduino to monitor temperatures and electricity usage
. For the temperature monitoring he picked up some 1-wire temperature sensors similar to those we’ve
featured in the past
. To pick up on electricity usage he’s not using an
amp sensors
, but because he’s in the UK he does have a flashing LED on his power meter. There’s a
known trick
to pick up these flashes with a photo cell to calculate energy usage based on meter readings. Finally, the data from the three sensors (indoor temp, outdoor temp, and energy usage) is piped over the Internet via an Ethernet shield so that it can be collected and graphed.
[Willem] has had the system running for a year. If you’re nosy you can look at the
temperature graph
generated from his collected data.

Nook Rooted Without Being Opened

If you’ve got a nook, and wanted to get root privileges, but really didn’t want to open up your fancy new toy. We have good news. The people over at
nookdevs
have found that the nook looks for updates from the external microSD slot at boot time. Simply
download the patch
, load it and boot. Though it was previously possible to get root privileges before, you had to
physically open the device
. While we would have opened it anyway, we understand that there may be people who prefer not to.

[Lucas] is
at it again
this year. Not satisfied by the computerized systems available on the market, [Lucas]
decided to build
on last year’s project. To save a bit of cash, he built the setup around Parallax’s low-cost
SX28 proto board
. The system is capable of controlling 102 channels, with 8-bit dimming. 6 boards control 7 channels each and are communicated to through a serial protocol (reducing the whole setup to only 36 feet of wiring).
More importantly, he’s teamed up with 3 other neighbors who also share a passion for outdoor Christmas lighting and they’ve put together the
Christmas Tour of Lights
. Money raised from all donations goes directly to the
St. Jude Children’s Reasearch Hospital
in Memphis, Tennessee.

Or do you just want to tell others what they should do in order to live in ‘your perfect society’?If you want to change the world to your liking, your time might be better spent joining Greenpeace protesting oil rigs on a rickety boat leaking diesel into the ocean. Or maybe hugging a tree in the upper northwest or Amazon rain forest. But by all means, get a life and an education, and develop some common sense and critical thinking skill, ’cause, damn…",

Kindle DRM Cracked

Ding-dong, the DRM is gone. But not in the way we really want. The copy protection scheme that is used for most Kindle books
has been cracked
. We’d much prefer it hadn’t been there in the first place but then there’d be no challenge for security hackers.
Giving credit for the advancement gets a little messy. Apparently two folks figured this out at approximately the same time. [Labba]
posted about his discoveries
while [I (heart) Cabbages] wrote about his exploits
in a blog entry
. Either way, you can now strip the protection and use your legally-purchased books on any device you choose by using this
Python script
.
This means that both Kindle and
Nook have had their DRM broken
. Are these companies really trying to prevent copying (fair use) or do they just want to be able to tell the publishers that there are copy protections while turning a blind eye to what happens in the privacy of your personal computer?

They want to say to publishers that their platform is secure.That said, if the product sells to the intended demographic (as opposed to just geeks), the vast majority of buyers will never even really know that they can hack it. So the gadget stays secure for the part of the market they care about and people will still be paying for books.I liken it to the iPod. What percentage has installed RockBox? What percentage has used an alternative to iTunes? I’ll bet both figures are pretty small.",

[Jeff] and his team completed this
iPhone controlled rocket launcher
as part of their final project at Georgia Tech. Two servos provide the rotation referenced by an onboard electronic compass, and elevation control for launch. These are interfaced with an
eBox 2300
using a few
Phidgets
boards.
Check out the launch video below. It’s too bad that they went with a commercial solution for servo control rather than building it themselves (especially considering it is an embedded systems class). But it is a nice build none the less. Now they need to
add some imaging equipment to the rockets
and they’ll be in business.

The folks
over at [Soup]
, a British marketing agency, thought up
this cool project
. It’s a set of handbells hooked up to an Arduino, actuated by central locking motors found in car doors. By the look of some pictures, there was also
a Lego version
. Songs written by users (through the online interface) are placed in the que of a server. Once it’s time for the song to be played, serproxy sends the Arduino an appropriate set of commands for ringing the bells in sequence. All of this happens in the [Soup] office while it is streaming live through a webcam.
We think that this is definitely a great way to use surplus auto parts. After all, not everyone
can build helicopters
.
It seems as though the bells are down for the moment, or the employees got a bit annoyed at hearing them constantly ring.

Yet
another
netbook
can now run OS X
. This one happens to
be the Samsung n310
, making it our first published
non-Dell
netbook to accomplish the feat. The key lies in a custom (and downloadable) .ISO for intalling said operating system onto a netbook. Full instructions for the task, and an audio driver for the n310 in OS X, are available on the [ComputerSolutions] website.
Oddly enough, the platform swap probably
‘freed up’ some space
.

All would be valid.I find your insistence that decimal isn’t reality quite insulting. I’ve worked on image formats in the past – they’re heavily binary, and I loved it – but I’m still not deluded enough to miss that metric vs binary only affects your perception of the HDD space. You’re still getting the exact same amount.And since HDD manufacturers have always (in the past 5+ years) stated they measure capacities in metric, I don’t see what hackaday’s beef is. I mean, it’s a spinning platter. That’s analog technology. Mathematically you should be thinking circles rather than binary.If you want a beef, check out SSD manufacturers. Many advertise 32GB, but most are only 30GB (metric), which means about 27.93 GiB. *That* is false advertising – and since NAND is more digital than analog, it should be measured like RAM is.",

"content": "that cherrypal actually kicks ass compared to the old laptop i was playing with. i could have bought a cd drive and ram upgrade for under 40 bucks, but it was a 166mhz with 32mb ram, and i blew up both my hard drives plugging them in wrong to my 44 pin to desktop ide converter. then i was thinking about spending like 30 or so to get a 44 pin to compactflash, and a small compactflash for it, because the hard drives i had for it were 2 and 3 gigs. but i took it apart and putting it back together didnt make it work. i think theres some ground connection to the lcd that im missing, but since i screwed up my ebay bid to win the one with another 32mb stick and the missing cd drive, and hd, i will just sell it on ebay as upgrade parts, because most of the people playing with that laptop have 133mhz and 16 or 32 mb ram, i can let them upgrade to 166 and 64, which should make it a little more possible to find a linux gui for it that doesnt suck. everythings better but the screen size, but since i was looking into buying a lg incite, i guess screen size isnt a problem. Thats the sort of computer that i would give to my little sisters, because they need to learn to use computers like the rest of the world. they can break the shit out of a laptop quick too! less than a month i had this dell with wifi. i had it full of emulators and roms. they poked the screen because i had previously had them playing with a fujitsu lifebook, touchscreen. lol the lifebook had no optical drive, and my youngest sister turned Iexplore.exe into a scribbly .bmp file so i was like dammit and i found something like netscape hiding out on the hard drive, used it to get online and download internet explorer again. then traded it for the dell after i cleaned it up, the dell ended up with keys ripped off, bruised up lcd, and a shorted out motherboard because the puppy chewed up the power cable. all in less than 30 days. that dell was far more badass than the cherrypal, and it was actually won in a raffle for like $25. because some business was getting new computers. it was over 1ghz and at least 256 mb ram if not 512. wifi card, external cdrom. nice sized hard drive. all lost because i was in oklahoma, a part of oklahoma where there is very little wifi and you have to go to the library to get online.so anyway, with them living in oklahoma, and being homeschooled, and having little computer experience, i need to send them something like that, or OLPC but i can never catch a deal on those things. that is the sort of thing they need though, something made for kids in developing countries. because compared to everywhere else i have been, that part of oklahoma IS a developing country, and its sad to see kids growing up without computers.anyway, more on the MAIN topic, OS X is a mac thing, right? so its not free like linux, but more like free like ‘windows xp performance edition’ lol torrents. OSx is something i have never tried, never heard too much about, and wouldnt mind giving a shot, if the process were legally as simple as downloading all these different linux distros i have been trying out. lucky i found my old cdrws because i was wasting way too many cd-r on overrated distros. or maybe they are good and they just needed more ram. SliTaz>DSL (in l337ness) AND SliTaz<DSL (in MB)but i am far from l337 enough to configure a wireless card in SliTaz. or DSL probably, but i h8 dSL because of the 'graphics' (they are text)ooh 'The key lies in a custom (and downloadable) .ISO for intalling said operating system onto a netbook.' okay that resolves that issue. now i want to try it, that way i dont have to read peoples reviews and be let down because its not as awesome as everyone said (DSL)",

[ZodTTD] has released a
Nintendo 64 emulator for iPhone
. It is available (for a price) at the Cydia store and can be installed on jailbroken iPhones. The video shows Wii Remote support as a control interface that uses both buttons and the accelerometer, an addition since we last
looked at his work
. There is no word about nunchuck functionality, a must if you’re going to try to 100% Mario64.

Reverse Engineering Off-brand Media Players
|
Mike Szczys
|
[
"classic hacks",
"handhelds hacks"
] |
[
"media player",
"portable video"
] |
[Marcan] picked up this device on the cheap and is
working to reverse engineer the controller
. This media player is an off-brand Chinese model that can be
had for the low-low price of $33.97
with free shipping. That’s worth it just to scavenge the parts for other projects, but the challenge here is to hack the controller because a datasheet was never produced for it. Warm up your logic analyzer, check out the
wiki
, and you can be pounding away at this
ARM926EJ-S
based system in no time.
The call to arms comes from [Marcan’s] blog. You may remember him as the guy who is working to solidify
iPhone sync in Linux
or… what else did he do? Oh yeah, he had this little project called the
Wii Homebrew Channel
a while ago. Get involved and you can learn from some folks who really know what they’re doing.
[Thanks Mr. Seeker]

Want to take your SNES emulation to your friend’s house? [Chris] worked out a way to fit
the important parts inside of an original Super Nintendo controller
. He removed the case from a 4GB thumb drive as well as a USB hub. Using a
RetroZone kit
he gave the controller a USB interface. By soldering the thumb drive and RetroZone board directly to the hub he’s reduced the package down to just one cable. Everything fits inside the controller case and now when you plug it into the computer you can fire up the
ROMs you copied from your original cartridges
that are stored on the thumb drive.
Of course this isn’t limited to SNES emulation but the real question is can you boot from the thumb drive?

Rhythmic Combo-lock

"dorm",
"lock",
"rhythmic",
"Teensy"
] |
[MusashiAharon’s] dorm room
door was practically begging to be hacked
. There was already an electronic strike plate in place as well as junction boxes on the inside and out that were connected by conduit. Jumping on the bandwagon after seeing some
other
door lock hacks
here, he built one that uses a rhythmic combination.
The control panel on the outside is a blank faceplate with two buttons and a status LED. Theses are wired to a jack and connected with a cable traveling through the conduit to a breadboard on the inside of the door. Seeing a large breadboard hanging on an outlet cover is a bit comical but it does the job. From there, a
Teensy
microcontroller waits for the code and if correct, actuates the strike plate via a relay.
The rhythmic nature of this lock reminds us of the
knock-based system
. One button signals the start and end of the code, the other is used to input the rhythmic sequence. This does seem a little more discreet and we’d imagine it’s quite hard to eavesdrop on the correct combination.

How about the date or the hour; and/or a specific letter combo in the date or hour.Security is an approach based on many factors, and must be balanced against the probable attacks and how secure the physical location is. For all we know there is an accessible window.Who wants to gain access and how motivated are they?Since it is a push button, you could use a camera to watch the presses.I always like the idea of a keypad of colors or moving numbers and letters. You know what to enter but the buttons will be different or they will ask you the question.Another possibility is using half-polarized LCD touchscreen, you need to wear polarizing lenses to even see what it is you are pushing.If you wanted to get even crazier you could hide the switches on the knob and use a “chord” of multiple fingers to press them, perhaps while simulating key use.There are just so many options, I think it is an excellent hack, whatever its perceived deficiencies.",

Create Digital Music Wrote a
semi guide
for Linux music creation and interaction after interviewing the L2Ork group.
L2Ork
is a Virginia Tech based Orchestra that use only laptops loaded with a custom Linux kernel, Wii remotes, and
home built speaker salad bowls
to produce some
surprisingly amazing music
. We’ve seen
music creation from Wii Remotes
before, but it didn’t sound anything like what L2Ork has created. The best part of the project, there are several videos and guides produced by L2Ork so you don’t have to attend Virginia Tech to produce your own music.

[Hydronic] did some tests to make his own
current sensor using a c-clamp
wrapped with wire. He tried several different cores including an aluminum carabiner, the C-clamp, and what he calls a u-lock (removable chain link). There is some success here that could be improved with cleaner winding and by adjusting readings based on the length of wire used in the wrapping.
This did make us perk up a bit right off the bat. Reader [Mure], who tipped us off about this, suggested that this could be used to make your own Kill-a-Watt without including it in the circuit. We made the jump to house monitoring. We’d love to have a data tracker for our home circuits to curb wasteful energy use. Perhaps we’ll try to make our own sensors and produce a diy
Cent-a-Meter

The current in what is now the secondary will equal the primary current divided by the turns (voltage) ratio. The load current should be no greater than the rating of the low voltage winding, which is a bit limiting.For example the 2155 (MM2002) LV multitap has some tappings only one volt apart giving a ratio of 240:1 so at the rated 1 amp the secondary current will be 1/240th or 4.17mA, and if loaded with two 120 ohm (5w wirewound) in series will produce one volt per amp.For higher powers a few turns of well-insulated wire can often be added around the outside of the winding through the spare window space (or the LV winding could be stripped off). To find the turns ratio, energise the tranny normally and accurately measure the voltage across the new winding. I have one of these in a box with plug and outlet so it can be simply placed in series with an appliance (fridge consumption tests).Since it is the *current* that is defined in the CT secondary you set the required voltage span with the load resistor value. This resistor must be *securely* attached to the secondary so there is no chance of it coming adrift in use (with resulting fireworks). It’s overkill but I use 5 watt wirewound.",

You may have to check several TVs before you can find one that is not glued in (make sure you are aware of the high voltage dangers that lurk inside a TV). These cores are made of two C shaped pieces that come together to form a square O shape. These will be superior to a steel clamp because there will be no losses due to eddy currents.If I may simplify what Roly said, the proper way to use these is to make the secondary a closed circuit and measure current. This way you are actually measuring the current of the circuit (divided by the number of turns of wire) and not dI/dt as you would if the circuit was left open and voltage measured. The way I did this was by connecting a 0.1 ohm resistor (a bunch of 1 ohmers in parallel), which almost makes it a closed circuit. Then run the measured voltage through an amplifier and use ohm’s law to find the current.In order to measure power you also need to be measuring voltage and compute the average of current*voltage over time, taking thousands of samples per second. Or, just use a specialized power measurement chip like the one mentioned in the instructibles article linked above. To correct an earlier statement, the current waveform is NOT sinusoidal. Electronic devices (switching power supplies) create significant current spikes.",

[Travis Goodspeed] took an

and posted his findings. In particular he’s looking at the
CC2430 System-on-chip
. These chips have a debugging protocol that is not hard to implement if you know what you’re doing. Certainly his tips make it easier for the rest of us. Don’t miss the info about reading from, writing to, and overcoming security of this hardware.

We like a good flight simulator but often find the available control schemes lacking. [Roland] not only builds his own controls, but
creates full cockpits that add physical motion
to the mix. He completed his third generation cockpit last year. It’s pictured above as well as in video after the break. That design uses a belt system to move the tricked out cockpit.
Now he’s started work on prototypes for generation IV. This time he’s using three Sarrus linkages to replace the belt system. We saw these linkages yesterday in an
extruder prototype
and if they can handle the load they should work well for this application. Video of the prototype is embedded after the break but be warned, the lewd thrusting motions are not for the faint-of-heart.

We honestly thought
[Jason’s] VFD clock
was some form of new terrorist attack when we came across the RSS. Thank goodness our relations with Russia aren’t as
MAD
as they used to be.
The main components are an IV-18 VFD with a MAX6921 driver, which to an untrained ear do sound surprisingly threatening. However an Arduino settles our hearts down and assures us this only has as much potential as blinking a VFD. While the main code, schematics, and CAD aren’t available (open source coming
to a theater near you
soon) at the moment – you can check out [Jason’s] inspiration, the
Ice Tube Clock
, which runs many of the same components.
Enjoy a video of it in action after the break. We love the ‘countdown’ feature the most.

[Michael] got his hands on a refrigerator that he intended to store beer in but found that it ran constantly. Instead of buying a new thermostat he and his friend [Doug] set out to build an
Arduino-based controller for the fridge
.
The finished project will switch 240v so they’ve used a transformer to power the logic circuitry and a solid state relay to handle the load switching, with a Dallas 1820 for temperature data. Because the Arduino offers more capabilities than the
average thermostat hack
they also decided to tap into its potential by adding an Ethernet shield. We see the Arduino as a prototyping device and so do these folks. Once the bugs in their first PCB prototype are worked out the circuit will use the ATmega328 and do away with the Arduino.

"content": "What an amazing coincidence!I just replaced the controls and sensors on my mid-range pricing electrolux/frigidaire side-by-side… it is a long story. I make candy as a hobby, and I have other friends who also enjoy my hobby. Also, I am “common law married” to a very skilled pastry chef here in Massachusetts, so the refrigerator is of central impotence in my life.I want to point out that frigidaire/electrolux products are in fact designed by people who care too much, and that many of them went on to design the Vista operating system,which was later marketed as Windows 7.But let us return to Frigidaire/Electroluxe.It turns out that these firms had a long run of bad designs between 1996 and 2010. Many of these involved “economic engineering” – you know, of the “let’s ditch the crusty old farts and replace them with some young guys who understand the internet and social networking” variety”.The new breed was very focused on the future.However, this didn’t work out so well for the consumer, as ICQ turned into AIM, and AIM turned into facebook, and facebook turned into a popular place to avoid doing actual work.By 1998, the average life span of certain brands of appliances started dropping, and by 2003 had dropped from ~2.7x down to about 1.3x, where x was the warranty period.Of course, since that Edward Deming guy died, 1.3x isn’t what it used to be, so let’s pretend that it’s now a random number providing us with a working appliance for something between 30 days and -rarely- as much as 9 years.We made it to 7 years before my refrigerator started making Darth Vader “breathing” sounds a few months ago. A few hours of googling revealed that almost any appliance attached to the firm of electrolux/frigidaire (they have about 30 names) seems to have dreadfully short lifespans… and in every case, repair was “non-economic”.Being the chipper supporter of the american way that I am (I plan to vote Palin 2012 and hopefully she’ll replace the constitution with a modern EULA modeled after the very successful one used by Microsoft), I decided to fix the system the right way… by ripping out the control board.The control board wasn’t broken, by the way – it’s just that bad software costs less than good software. The holidays were coming, and we had a lot of candy to make and pack for the gift shops.Also, I am unemployed, so I must run our business by default. However, I had most of November to work on this a little at a time.Refrigerators are not sophisticated. It wasn’t hard to locate the sensors – and replace them with solid state temp sensors, including drilling and epoxying new sensors spaced at 10 inches up the side of the fridge, as well as at various points in the freezer and fan compartments.Let me be the first to say that I went overboard, using almost 24 temp sensors, 4 current sensors and two thermocouples. I won’t say what board I used, but my craptacular software lets me either write or read a string to the system from a PC.Writing simply turns things on and off (compressor motor, vent controls, heater, etc). I left the fridge light and water/ice dispenser alone, apart from reading the temps and motor status.I basically read a long string of ASCII hex that corresponds to each sensor with resolution equal to about 10 bits. Accuracy isn’t much to write home about, either.Before I pulled the board, I recorded the values for 3 days. I made some mistakes in writing the software, but the fridge was basically empty (we have 3 of them, thanks to late 20th century economic models) at the time. Also, the electrolux/frigidaire had been spoiling milk for some months, so we were ready for the worst.Did you know that milk often sits unrefrigerated on docks for hours at a time before it gets to your display case? You do now. It’s also common practice to turn off the refer portion of trucks for several hours and overnight to save fuel.In fact, I had assumed that this was the cause of our milk going bad so frequently until I discovered that my fridge was randomly popping up to 54F for a few hours every three days.BTW, my problem was ice buildup on sensors due to issues with the ice maker. The electolux/software didn’t take this into account, and was telling the fridge to both blow and not blow at the same time. Life on mars, as it were.My housemate/life partner (let’s call him Klaus) is not happy at the fact that I have done this, as it took a great deal of time. Also, the fact that I re-purposed our Kitchen’s electronic picture frame to provide status information has annoyed him to no end, and as a result I did not find any fudge in my sock, only peanut brittle and a Sarah Palin calendar.In the end, it was not cost effective, and we will likely buy a new unit. However, I am very happy at the results. I will say this:1) Use relays for low duty cycle AC control, and solid state relays or zero-sensing Triacs for variably duty cycles.2) It is as easy to wire 8 sensors as 1, if you use a multiplexor or use I2C sensors. Calibration is another story, because I needed to measure below 0C, so one must use dry-ice. Better to use pre-calibrated sensors. Calibration was the worst part of the project.3) low cycle times with some temperature drift is better than continuous control. The compressors do not like to be manhandled, so you should try to control the fridge side with the fan and vanes.4) I worried about drilling the insulation, who knows what this is made of?5) Read a few articles on refrigeration before you do this. You can easily replace a thermostat, but if you want to be more sophisticated, you should understand the cycle.6) MS C sharp is the new visual basic. It’s like C flavored VB.My next project will hopefully be an automated fudge packing machine. It will be powered by an arduino, since I am curious about such things and often see them mentioned here.The problem is that Klaus and I have so little time together – It is my desire that we can make each batch, and then put the slab into a machine that will cut the pieces and arrange them.I hope to also have each piece wrapped in tissue, but my mechanical abilities are not so good.",

C sharp is not my first language, though, so I am not used to Hungarian notation other than what I have read. Once again, Microsoft leads the way!Because of this, the system was trying to keep the fridge at too warm of a temperature, but it was a simple mistake. I am not expert, I just know sensors and some programming.The picture frame as a monitor was a stupid idea, it would have been easier to just put an LCD on top of the fridge, but as I worked on the project I realized that Klaus didn’t like the wires hanging everywhere.I stole the frame idea from another project here on hackaday some time ago, I used it to put up funny pictures when my parents came to visit us.I know some electronics things from my father, who built instrumentation, as did his father before he moved to Georgia. My grandfather lived in the place where I met Klaus, Peenemunde in Germany.Also, my grandfather moved back there in 1978 and started another family so we all visit them.

RFID Control Concept

"xbee"
] |
That’s not a smoke detector, it’s an
RFID detecting puck
. [Eric] and [Brent] have been working on this concept to produce a virtual knob. When the device detects an RFID tag it vibrates, then the puck can be turned like a virtual knob, an accelerometer picking up the motion data. The build is rounded out with a XBee module for connectivity and housed in a printed case.
The video after the break shows the device controlling colored lights. There is a different tag for each color and when the reader is over one of them the puck can be rotated to turn brightness up or down. We foresee a lot of great uses for this. Turn it into a thermostat for public places by adding a character display to the mix. A tag can be affixed to a wall, when you want to change the thermostat setting just hold the puck over the tag and turn until the screen displays the desired temperature.

"content": "I never really caught on to the idea of these sort of systems where physical tokens permit access to features.The puck has to be able to specify back to the control system which light / room you are adjusting, so everything you need is already in the puck. If you put in a switch or menu on the puck to choose a channel, then you don’t need to be tied down to wherever the rfid tags are located. It becomes a true remote control and GAINS functionality compared to a permanently affixed wall thermostat or light control board.But the system as depicted gains very little over a permanently located controller. If the tags are in one place, you still have to go THERE with the puck to change anything. Then you have to feed the puck batteries, whereas a permanent control box / board in that location could be wired up to power and maintenance free. If the rfid tags are near each light, or in each room – you now have to take the ‘key’ (puck) with you to each one in order to adjust it, and cannot make local adjustments without first finding where you left your key/puck.This really only brings two possible advantages over dedicated systems: One is that one can apply the same interface (puck) to multiple systems – one puck, interfaced with the requisite computers / control systems – could open doors, operate windows, hvac systems, lighting systems etc. Just put a universal “put your puck here” marking over the rfid tags on EVERYTHING in your home and just carry the puck around. Which ties into the second advantage, is that it truly becomes a key. If everything has the rfid->puck->computer interface as the ONLY control point, someone without a puck can’t screw with your settings.",

Hacking The OnStar GPS V2

[Andy] has provided us with his new guide to
hacking the OnStar GPS
. Previously, we have covered a way to grab the GPS data from an
unused OnStar system
, however in recent years GM has added much more complex systems, which make it harder than swapping out a serial line. For the new version, [Andy] has figured out GM’s Controller Area Network (CAN), which they call
GMLAN
. He has also done most of the software snooping and sleuthing, and has mostly solved GMLAN’s method of announcing GPS data. There is sample code available to convert this information into generic latitude and longitude.
Unfortunately for the project, (and very fortunately for [Andy]), he has a child on the way and new job responsibilities, so he is offering up his results to the HaD community to finish up, double check, and provide a good how-to for everyone else. To anyone who decides to pick up this project and run with it,
let us know!

If you were building a car PC, it would be easier and probably cheaper to just plug in a USB GPS receiver and be done with it.",

If you could install a CAN sniffer and have them disable the car you could likely see what command they send.Most switches and buttons in modern cars are CAN. In many cars it is normal to have the power window switch simply send a CAN message to your power window motor to raise or lower.

Hasn’t reduced the amount of wire in a car either, like was touted back in the 80’s when “multiplexed” systems for car wiring were first bandied about.So now, instead of simply pushing a couple of contacts together in an inexpensive switch, a light “switch” is a Rube Goldberg or Heath Robinson affair of digital electronics that costs a small fortune to replace when it quits working VS being able to carefully take apart a real switch and clean the contacts.That’s led to BS like the latest Camaro where the controls for *everything* are integrated into the radio. Remove the radio and the car won’t start, can’t even turn on the lights! Metra has reverse engineered that junk and makes a kit (sans radio) so an aftermarket radio can be installed – and the car can be driven.The movie version of Bumblebee being a Camaro who can’t talk and has to communicate using the radio is a bit ironic given how removing the radio will completely disable the real car. Should’ve used that in one of the Transformers movies – some thief steals Bumblebee’s radio when in car form and he’s inert until another one is installed.",

If there were a GMLAN bluetooth converter (ELM327 would be a huge plus) I could integrate this into another project I’m already working on with the Droid phone (Project name Voyager, not released yet) and controlling the vehicle via OBDii/CAN. GMLAN is on a separate LAN in the vehicle I think but if GMLAN could be accessed from CAN that would be really cool and lots of possibilities.",

For one, the Onstar’s installation is optimized for reliable reception and is better than built-in patch antennae. Another is the selection & versatility of PC/& Handheld software compared to street or trail units. You can combine GPS and Google earth running in cached mode to track yourself in realtime with satellite imagery. Can’t do that with a hand-held. Also Onstar’s GPS doesn’t have a long delay finding sattelites in a new location.Is there a service port we could use for a no-cut mod? I imagine plugging in a bluetooth link that takes power from the plug. I could probably work up a PIC board with a bluetooth module PDQ.",

Aerodynamic Tail Makes Geo Metro Even Cooler

[MetroMPG], an environmentally friendly car enthusiast from Ontario,
added a tail to his car
to increase gas mileage. This 1998 Pontiac Firefly is a sibling of the cheap and popular Geo Metro. He had already done some work to cover a portion of the rear wheel wells to reduce drag. Using cardboard, duct tape, and an aluminum frame he extended the rear of the car by around six feet.
The results are pretty impressive. His extensive testing can be seen in the video after the break and
reveals a Miles Per Gallon increase
of 15.1% at 90 km/h to get to 64 MPG. The tail is removable but we’re thinking it’s a pain to keep relocating the tail lights from the original body to the removable one.
Now we’re wondering if someone is doing this to our Smurf-blue Metro that we sold to the junk man for $100 back in 2001. It ran great, if you weren’t caught in the cloud of blue smoke coming out the back.

Weight makes a difference on acceleration, once the mass is accelerated it isn’t a problem. Unless you notice the difference in your cars’ fuel consumption between a 3/4 tank and 1/2 a tank (approximately the same weight as this mod), you won’t know the difference, except the car will use much less fuel and have better hihg-speed handling and acceleration.Interesting how the haters shut up when fuel goes above $4 a gallon ;)",

Sure better gas mileage at the cost of traction.2) Plain old lift of the tail, once again trading MPG for traction.3) Subtle changing in driving pattern since this was not a blind A/B testing. Maybe if he had others drive the car with some quick training to see if there was a statistically significant difference between the two tails.Honestly I’m betting that he is trading traction for MPG and this is probably a dangerous trade off for highway speed.

You’re Not Seeing Double: RGB Christmas Trees

[mrpackethead],
created this monster of a tree
. As shown in the video, it’s capable of showing animations, patterns, and potentially video. The 6m tall creation is studded with
2000 waterproof RGB
LED modules. Software for the tree was written in
Apple’s own Quartz Composer
and
integrated into Madrix
, a piece of software designed with the purpose of controlling LEDs. The 600W system is
100% Arduino-free
and costs less than the equivalent of 0.04USD per hour to run in New Zealand.
[Geoist] opted for the Arduino way to
rig up his own
smaller RGB Christmas tree. Finding a slightly kitschy fiber-optic model in his local department store, [Geoist] was eager to harness its colour-changing powers. Upon opening it up, it was discovered that it was controlled by nothing more than a light bulb
and a spinning disk
of coloured light filters. [Geoist] gutted the setup in favour of a breadboard with 3 RGB lights hooked up to an Arduino. The sketch for it is available on his site.

And as for XMallRun, feel free to email me and will educate you on where and how thoose modules came from. Your lack of knowledge and experience in so called hacking make me wonder about you.

Germany i can tell you .. and for the comment “What next? Hilter is Santa Claus” I can only tell you he was a real true human with a heart , he gave to the poor presents all made by himself , small things that make happiness.Today every little greedy buisnesman/whoman want people to buy presents for as much money as possible. Look at those people every year misunderstanding the consept about christmas , where is the spirit i ask you ?I remember from my childhood , I hate all those blinking lights , but i love the old traditionwith Candels , small things on the christmasthree,This today are so ugly i have no words , you can even see the tree for blinking lights.———————————————–And you write this to me->“feel free to email me and will educate you on where and how thoose modules came from.”Thanks …You educate me ? Now i have to laugh ha ha ha …..I have made things out of electronic since my childhood.. No you dont find them on my page , Why ? because it’s our music page .We have other pages.I made my first electronic guitar amplifier as 11 year old .. ok .. You have something equal hereyou made things from -> Audinoboards Athmell Ect Ect allpremade boards and with a little socalled hacking , Phew this reminds me of Lego . Modules putted togeather , try at least before you writeto look at yourself. People screaming up like you ” come here i will educate Ect Ect ” In the real world they know so little and fool themselves like you do. You don’t know what i can made AND you try to tell me what to do , Ha Ha .You said this–>“TRY and learn from people instead taking and putting them down.”Im not putting them down , but i tell you what i hate about people like them do.So those smallbrained people destroy christmas spirit with all those Plastic and Blinking lights.And for the comment about im a communist , YES I AM… and it’s clearly that you are a stupid american capitalist. Youn can’t see the beauty in the small and the spirit you talk about are gone .Mrpackethead wrote –>“I’m so sad that you are not enjoying Christmas. Our neighbors love our lights. In fact next year, they are joining in as well.”Fu… You Im trying to enjoy christmas , but all those stupidos with their blinking lights destroy the spirit . we have an idiot in our town making this every year and it destroy all the small things people create in there gardens. A littletree with a few lights and so on are much more beautyfull …You said–>“We’ve had thousands of people come to see them”Yes typically american , they will do anything to be in focus and doo all they can to be in center of others.. ” hey came and look at me” mentality , Phew Everything pushed to hights and so big as possible , typically american.This is another reason why im a communist….Americans always try to be in center of others and make themself on top of all others.You write –>“and they go with smiles on their face.”Yes typically american … Beside this lightshow youn can find a little beautifull christmastreewith only few lights , lightning just a little in the dark and its beauty will newer being noticed , typically “the more , the better , the bigger the better ” Phew you have NO ChristmasSpirit both of you….",

Learn before talk .This is communism :The political theory of socialism, which gave rise to communism, had been around for hundreds of years by the time a German philosopher named Karl Marx put pen to paper. Marx, also known as the father of communism, spent most of his life in exile in Great Britain and France. He wrote the Communist Manifesto in 1848, which later served as the inspiration for the formation of the Communist Party. Communism is also known as “Marxism. Marx believed that a truly utopian society must be classless and stateless. (It should be noted that Marx died well before any of his theories were put to the test.) Marx’s main idea was simple: Free the lower class from poverty and give the poor a fighting chance. THIS IS THE PHASES IN COMMUNISM. Phase 1: A revolution must take place in order to overthrow the existing government. Marx emphasized the need for total destruction of the existing system in order to move on to Phase 2. Phase 2: A dictator or elite leader (or leaders) must gain absolute control over the proletariat. During this phase, the new government exerts absolute control over the common citizen’s personal choices — including his or her education ( if we need 100 busdrivers it is stupid to educate 10000), religion (if the religion are against human rights it will be forbidden ) and employment . Collectivization of property and wealth must also take place. Phase 3: Achievement of utopia. This phase has never been attained because it requires that all non-communists be destroyed in order for the Communist Party to achieve supreme equality. In a Marxist utopia, everyone would happily share property and wealth, free from the restrictions that class-based systems require. The government would control all means of production so that the one-class system would remain constant, with no possibility of any middle class citizens rising back to the top. the major social and economic problems we face today can only be resolved by putting an end to capitalism and establishing socialism; to achieve socialism, the working class and its allies must take political, economic and state power out of the hands of the capitalist class; decisive advances towards socialism can only be achieved by mobilising the mass of the people in support of an intermediate alternative economic and political strategy which aims at securing full employment, a general improvement in living standards, a wide expansion of democracy and a genuine policy for peace.With other words all are equal and no one more than others .Have a happy new year.",

It’s a Guitar Hero Christmas
Nope, we’re not adding Christmas songs to the game, but instead making the game part of the decor. [kumbaric] hung strings of lights on his garage door in the shape of this familiar gaming interface. The best thing is, you can actually
play the game based on these lights
. [Thanks Yuppicide]
Smallest… Snowman… Ever.
You can make one of these if you have an electron microscope and an ion beam on hand. This is the
product of some clever folks
at the National Physical Laboratory near London. This is a pretty fat snowman, 1/5 of a human hair across. By the way, you should have read the subtitle with the voice of
Comic Book Guy
(like we do when reading the tolls’ comments). [Thanks Matthias]
A little help please
[Andy] outdid himself with this
creative decoration
. Hanging a dummy from the gutter and placing a tipped over ladder beside it had some folks alarmed. The police asked him to remove the prop after they almost ran off the road while driving by. This was real enough that somebody actually came to the rescue, climbing to the top of the ladder before discovering the ruse. [Thanks Rob]
Lights that blow your mind
This video
is from a 2007 display and features over 45,000 lights running on 176 channels. Individually controlled colors, fading effects, and music synchronization put on a show that will get you kicked out of your gated community. Admittedly this guy runs a business dealing in Christmas lighting displays, but that doesn’t diminish the sheer awesome of what he’s done. [Thanks Patrick]
Have a safe and happy Christmas. We’ll keep our fingers crossed that you get that new
Weller
you’ve been hoping for.

[Dennis] got snowed in after the biggest storm in the history of the state hit. Like any good hacker he didn’t let the time go to waste. He decided to dig out his Neo Freerunner to
give it a decent battery and a new OS
.
The original battery for the
Freerunner
has a controller board integrated into the package. [Dennis] pulled out the board and attached it to a portable DVD player battery. After running it through a discharge cycle with another hack of his, the board learned the new battery capacity. The larger battery plus a
fast-charger from SparkFun
required a larger case. He made it happen by combining a 2.5″ HDD case with the original body courtesy of some JB weld. The final portion of the hack was to load up Android which is as simple as untarring the package onto an SD card.
It’s a bit big, but the battery will last and he’s got an open platform. Nice work!

Brain Controlled Game
If you’re a fan of biometrics this game is for you. It uses a
homemade EEG
to facilitate simple control. This is along the same lines as the
Force Trainer hacks
but this homebrew hardware is fun to look at. The success of the project can be seen in
the video
of a simple game they developed.
RF Camera Remote
[Jonny] wanted to trigger his Nikon camera remotely but was unhappy with the functionality of the IR remote. He
hacked together an RF remote and receiver
that still uses the IR functionality of the camera, but allows for the geographic freedom of Radio Frequency. Not as advanced as
some we’ve seen
but it meets his specifications.
CNC Mill
[Jan] tipped us off about a
CNC mill
that her friend made. The machine turned out beautifully even though very few tools were used to produce it. We love to pour over
these builds
so if you’ve done one, document it and
send it in
.
Neutering the On Demand Button
[Dan] hated his Comcast remote because the On Demand button could be hit by mistake. This was usually when trying to unpause live TV. The remainder of the show couldn’t be viewed just because the On Demand menu launched. Simplicity is king.
He fixed this
by placing two small paper rolls between the button and the circuit board. This way the button can still be used but only if you press pretty hard.

Christmas may be over, but we still have a couple of cool holiday related hacks for you. One being [Alpay’s] Twitter based interactive
Christmas tree ornaments
.
We tried to dig up some more information, but it thus far appears a laptop running Processing searches Twitter for specific Christmas related words (like 1337, that’s Christmas-y), sends a buffer to one of three Arduinos which in turn light up a specific ornament. You can check out a live stream
here
.
For those wanting a bit more information on Arduino and controlling holiday lights, check out [Alpay’s]
GE health care version
of Twitter lights, or our previous post on
controlling Christmas trees
, or you might even try [Michael’s]
$10 Walmart light controller
.

[Mike] covers his car whenever he puts it into the garage because the top is always open. After years of this ritual he decided to upgrade his garage to
automatically cover the vehicle
(link dead, try
the Internet Archive version
). The car cover, made from a few bed sheets, attaches to the bottom of the garage door. At the front of the stall the cover has two half-pound weights sewn in with plenty of padding to protect the car’s finish. Ropes attach to these weights, travel through a pulley system, and connect to the garage door opener carriage. This $65 dollar solution makes sure [Mike’s] car is always taken care of.

Unsuspecting office workers beware. You may already be in the cross-hairs of a
ping-pong ball launching robot
. This covert robot hangs out on the other side of a suspended ceiling, waiting for its operator to unleash the fury.
When put into action
a hatch in a ceiling tile is raised and balls are launched at a cowering cube-dweller.
It looks like the balls are launched at a reasonable speed and won’t
hurt anyone
. The next generation of this bot should do a better job of integrating the trap door and be quieter. This would be a lot more fun if the victim couldn’t figure out where the heck that ball just came from.

Does Your Phone Have A GOOG-411 Button?

While visiting family we noticed that their telephone had a dedicated GOOG-411 button. We’ve been using
Google’s free 411 service
for
what seems like years
but seeing this show up in the form of an
auto-dial button
is astonishing.
The question that pops to mind: how is this not an antitrust suit waiting to happen?
Directory assistance is BIG MONEY
that Google undercut when launching its free service. By shipping phones that have the number pre-programmed doesn’t that limit choice and competition in the same way that shipping Windows with Internet Explorer does? Perhaps the difference is that Microsoft has a near monopoly on the PC OS market while GE can’t say the same about cordless phones.
We’re not antitrust lawyers, and neither are you, but we’d still like to hear your opinions about this in the comments.

Well, my very non-legalspeak answer is that its just a “partnership” of sorts and those aren’t illegal.

[Rui] is working on
a sequencer to control his robotic gamelan
. The software maps out the controllers that operate
the musical robot
, which play the traditional
Indonesian instruments
.
The controls use ultrasonic distance sensors that detect the proximity of the musician’s hands. This data is collected by an Arduino and sent to a computer for use with the sequencer. The controller body is an upside down salad bowl from Ikea; cheap, available, and creative!

Home Made Panoramic Camera

This one is from way back in 2002, but we didn’t see it till today. This is a
hand built panoramic camera
. The film is laid out across the back of the case, and when taking a picture, the lens assembly rotates to expose the film. It is a very nice looking design. The brass body is quite
reminiscent of the recent one posted here
. On the site, you’ll find not only the build log, but a full explanation of all the math behind the design. It is a very interesting read, even if you have no plans on building your own.

Fake Snow From An Arduino

The team at [Sosolimited]
was contracted to create an interesting holiday window dispay
for the HBO
retail store in NYC. The Times Square display encorporates a board of LEDs and a machine for blowing the artificial snow particles around the enclosure.
The code for controlling the LED array was written on top of the open source C++ toolkit,
openFrameworks
and the entire setup is interfaced
through an Arduino
Duelmilanove. Multiple
Sharp IR sensors
were hooked up to the Arduino in order to detect the movement of observers, which in turn triggers fans to blow the ‘snow’ around. A National Control Devices relay board connects the heavy duty fans to the Arduino.
This video demo shows
just how attractive the project is in motion.

A Random USB… Hourglass

[Peter] thought of a
creative, way to generate
random entropy
for under $100.
The USB Hourglass combines a sand timer with a rotating mechanism and an optical beam through the center of the timer to observe the falling sand. The amount of light reaching a detector is digitized at frequent intervals and processed
by a microcontroller
to determine when to rotate the hourglass. The digitized light levels are also
sent by USB
to a host PC where they can be used as a source of random entropy. Power is supplied over the USB cable.
With the USB Hourglass, the user can look at the sand falling through the center of the hourglass and monitor the randomness in the USB output data. And one
can read the code
line-by-line, compile it, and upload it to the microcontroller using only open-source and widely supported tools.

New advances in laser RNGs are promising however.As for this project it is actually funny because I was thinking of a very similar idea, bouncing a laser off of moving sand and capturing the laser speckle with a digital camera.

Here’s an
advent wreath made from six parts
and a paper clip. Powered by a CR2032 3v button cell, the circuit has been free-formed using a paper clip as the conductor. We love the “dead bug” style of construction used with the ATtiny13 microcontroller because it adds an extra level of intrigue for the uninitiated. This project build on the
flickering circuit we saw last year
and uses the
LEDs as light sensors
, only turning on when a certain darkness level has been reached.
We used a tiny13 with our
Menorah project
last year and still have some lying around that we can use for this. We’re sure you’ve got at least a couple of low-pin-count micros on hand. If you don’t, you should!

I give it a few wraps around the upside down pin and then double check my wiring. Only after it’s been checked do I come back an do a quick dab of solder to keep it all together.",

It seems to me you are going to get a lot better performance with some sort of dedicated light sensor.

New AVR Simulator For Linux

simavr
is a software simulator for the AVR line of microcontrollers. You might be asking why anyone would write this sort of thing considering the simulator provided with AVR Studio is a wonderful tool? Well, a lot of folks don’t run Windows and don’t wish to use that development environment even if Wine or Virtualbox could make it happen.
We haven’t tried it out ourselves yet. There is a
discussion thread
going that reports some positive results of using simavr with
GDB
and
AVR Eclipse
. It’s a new package, but so far it seems to have put its best foot forward. Currently there is support for ATtiny25/45/85, ATtiny13, ATmega48/88/168, andATmega164/324/644 chips. Several of the common on-chip peripherals are already supported with the others on the way.
Have you tried it out? Let us know what you think in the comments.

Sarrus Linkage 3d Printer

"3d printer",
"reprap",
"sarrus linkage"
] |
[fdavies] has been working on
his own 3d printer
. He is using printed parts, but unlike the RepRap he’s purposed
Sarrus linkages
in his design. If it works, this should remove the need for precision rods in building these types of CNC based machines. He’s also recovered DC motors and optical encoders from some inkjek printers. Given that many retailers require you to take junky inkjets home when you purchase a computer we’re betting you’ll find friends happy to part with their unused hardware. We’re impressed with the motion of the prototype seen after the break. Let’s hope this leads to the next generation of affordable 3d printers.

They max out at about $10/lb for materials and power – the current design has around three pounds at full infill. The sarrus-based design probably saves around $80 in bearings and rod alone, and all parts only really have one obvious way to go together for assembling the machine. We’ve yet to see whether it can achieve the requisite positioning accuracy, but it’s not attached to mainline anyways.The “restriction” has more to do with a 3D printer being the cheapest machine to get and run available to produce the kind of parts it needs without needing skilled labor. Not using it, you either need a much more skilled operator to make your parts, or a much more expensive machine.",

Additional books detailed a sheet metal slip-roller and brake, a bandsaw, and various other devices – like a banjo. Dave was pretty eclectic.

This table, and the RepRap project in general, are ingenious hacks, plain and simple.However, they are focusing on something that you have already said was a good idea while dismissing the superfluous “third world” angle. 3D printing has a place in the machine shop. The Reprap project, and its spin off the Makerbot Cupcake, have turned simple rapid prototyping from something affordable by architects, geologists, and medical prostheticians, to something affordable by almost any high school – if the shop and science departments can pool a budget for it.Any third world use of a RepRap derived design is going to be in those developing second-tier economies that were intended to get the OLPC XO. (In fact, as a point of trivia, the arduinos used in this project were programmed from an XO.)Rapid Prototyping is not the be-all-end-all of industrial design, but having the ability to turn concepts into object quickly can be very useful and empowering. More than a self-replicating design, the RepRap is a CHEAP fabricator. It really already does the things you want a printer to do in terms of simpicity and cost.",

Mr. Davies is using an arduino to control the DC motors and read the optoendcoders locally. The control signal being sent to that board is the standard stepper controller signals that come off the motor board as with any other RR-based printer. The control pulses come in, a step-count is made, and then the closed-loop control system moves the DC motors the correct amount. As a nice side-effect, you can take the gantry and yank it totally out of position, and it ziiiiip back into place immediately.As far as efficiency goes, it’s a total loss. Adding another processor to the chain to avoid having to re-do firmware is terrible. However, being able to throw your own hardware under the standard RepRap software with a hardware-based hardware abstraction layer is pretty cool. I am hoping that this project will inspire/disgust some of the folks involved in the firmware design end of things to actually move to an abstracted-hardware design that is easier to modify at the end-user level.",

You know – critics lack vision, are evil greedy exploiters who don’t care about the poor, Reprap will literally save the world, etc.Every other critique of the Reprap, including on here, has been met with that so far. I wanted to head it off early by pointing out that even if for some reason you thought that people without electricity or clean water needed RepRaps this design path still isn’t the best way to do it.Like you said, I agree that this is mainly for first-world individuals and education. If that is the case, this is still a dead design path as more efficient, cheaper, and better quality units can simply be assembled with cheaper off-the-shelf hardware commonly available in the first world.So in either case the avoidance of cheap commercially made parts like rails is pointless.The people invested heavily in justifying it’s “self-replicating” status are using circular reasoning, or are straight up just being disingenuous trying to push the third-world angle.",

Some things are made to look steam punk but others
are
steam punk. This example of the later is a
camera made mostly of brass
. The body has been soldered together with only a shutter and lens being purchased for the project. There is a viewfinder and separate range finder to determine the proper focus for pictures as this is not a
single lens reflex
.
It should be obvious by now that this is a film camera. It relies on the photographer to turn the winder until an arrow on the knob lines up with a mark on the body for proper alignment. If you set out to make one of these, perhaps you should also
manufacture your own film
for it.

Bluetooth Handset Hacks
|
Mike Szczys
|
[
"Roundup"
] |
[
"bluetooth",
"handset",
"headset",
"phone",
"telephone"
] |
Cramming Bluetooth headset circuitry into an analog telephone body has become an extremely popular hack. With declines in the prices of these headsets, and older telephones being seen as storage-room-clutter this hack is just waiting for you to get started. Join us after the break for a look at what others have already accomplished.
Traditional:
The most common Bluetooth handset hack involves standard receivers. This is because they are relatively comfortable to hold and readily available. Chances are someone you know will give you an old phone for free if you just ask. Some of the important things to remember when sandwiching a Bluetooth headset into an old school handset is how to handle the buttons and how to charge the device. Some of these examples have routed the buttons and connector into the case of the phone, others just require the removal of the microphone cap for recharging. There’s no doubt that receivers
#1
,
#2
,
#3
, and
#4
all achieve the desired retro look.
Unorthodox:
We’ve
covered both
of
these hacks
before. The whimsical
iGiveUp handgun handset
is a social disaster waiting to happen. But if you don’t mind court-mandated counseling give it a try yourself. For those who want a phone that can be used at the airport, the
NES set
is a safe bet and has the added bonus of allowing you to carry around an old school controller.
True Vintage:
We were quite surprised that we didn’t find more hacks that involve some really old phones. Then again, these are antiques that most would not dream of cracking open. This
candlestick phone
looks great, but we image it’s not as comfortable to use as the more common receivers we saw earlier.
Steam Punk:
These aren’t handsets and one of them doesn’t have any electronics in it at all! But we couldn’t finish this roundup without a mention of the
Steam Punk styled Bluetooth headset
. The earpiece on the right is
a piece of jewelry
by designer [Chris Cobalt]. Truthfully, we’re kind of sick of seeing people wearing ugly plastic headsets everywhere they go. Make a statement and use [Chris’] design as inspiration to customize your dongle.
Commercial:
Handset hacks turned out to be so popular that they’ve started to pop up on the commercial market. Above are two of the better renditions. On the left is a
rotary phone model from SparkFun
. To the right are two examples of
Think Geek’s offering
. There’s plenty more out there on eBay and the like, but don’t you want to be able to say “actually, I made it” when people ask where you got your geeky peripheral?

This gun
hunts only RFID tags.[mnt], who brought us
laser gesture control
, built this RFID Zapper but included so much more. Any good weapon has to sound mean, a feat he’s accomplished by incorporating an MP3 player into the rifle. The coil that zaps the RFID tag is powered by a photo-flash unit, but for visual feedback he’s got a second unit that flashes light to signal the demise of your German passport (see the video after the break).
It’s hard to believe we haven’t covered RFID Zappers yet. The concept came out of the
Chaos Communication Congress
a few years back. This method works by sending a very strong electromagnetic field through the RFID tag that causes it to burn out. There’s a wiki post on RFID Zappers but Firefox threw a certificate warning when we loaded it up;

A big dump SCR might be an idea if you don’t want the button to weld closed.Fair warning; about 20% of the cameras I have ratted still have a major charge on the cap, *days* after they were last used.

Subcycles: Multitouch Music Controller

Subcycles is a sound controller application that [Christian] is using on the third multitouch display that he built. The screen is a sheet of acrylic in an aluminum frame. The image is rear projected onto an area covered with
Digiline dispersion film
. As with
other projects
that use the Community Core Vision package, a PS3 eye camera captures the touch information.
This build does a great job of including the audience in what the musician on stage is doing. [Chris] points out that the sight of artists staring at laptops on stage is becoming more and more common. The
‘Minority Report’
-like interface that Subcycles uses makes not just for interesting music, but for an added visual reinforcement to the live part of the performance.
[Thanks Mark]

If you’re more of a code monkey than artist, it may be tough to transform your ideas into the 3D models
necessary for fabbing
. The folks
working on openSCAD
apparently feel our pain.
openSCAD
uses a language
somewhat reminiscent of C for creating models. A preview of the model is rendered alongside your code. Fully cross-platform, it runs on Linux, OS X, and Windows.
Much like SketchUp
, openSCAD can also extrude 2D outlines into models. This feature comes in very useful if one already has a set of technical drawings for a part. With no price tag, it’s pretty affordable during this costly season.

However, KPovModeler at least is currently unmaintained and (currently) doesn’t support the flow control constructs (loops/if/else) of SDL or even variable declarations to reuse shapes.OpenSCAD uses OpenCSG, which on the website states *interactive* CSG (Constructive Solid Geometry) as one of the main benefits (http://www.opencsg.org/#benefits).BTW, for those of you with cursed 64-bit systems there are some changes you need to make to get OpenSCAD to compile:http://rocklinux.net/pipermail/openscad/2009-December/000033.html",

Fix A Projector On The Cheap

[j] sent in this nice writeup on how to
revive a dead projector
. he managed to pick one up for $20 that had a broken bulb. While the prices of bulbs have come down considerably, they can still be a couple hundred dollars. Being resourceful, he decide to just use a halogen bulb that he picked up at his local big box shop. In the photos, he’s using a 50w mr16 bulb. The results really aren’t too bad. Especially considering that his cost for the entire project is now roughly $25. He does, however suggest that a 100 watt bulb wouldn’t be a bad investment. His projector seems to need some cleaning and adjustment in the lenses as well, but for $25 it isn’t too shabby. We’ve had this submission for a bit, but it didn’t have any pictures of the projector actually working. During our conversation, we may have possibly suggested a picture we’d like to see. You can find it after the break.
We did cover a very similar one last year, which had the
driver integrated into a custom bracket
, but the project page seems to be gone. There is also the possibility that the projector you get doesn’t just have a bulb problem. Sometimes it is the
polarizer that needs replaced
.
Egotistic? Never.

I just never thought replacing the color wheel was something that a user could do (special tools, etc.). I took this one into a non certified local repair guy and he serviced it but could not do the color wheel as he had no source for parts (not being an official InFocus repair guy). I’ll take a look online though! Thanks!Thinking of replacing the InFocus projectors – can anyone recommend a bullet proof, well supported, awesome looking “full resolution” HD projector? Currently using component but HDMI is not out of the question in the future. Probably something in the < $5K range…I know that some of the pico projectors use three bright LEDs. I was hoping that someone would come out with a \"regular\" projector based on the same idea that did away with the color wheel. No color wheel and LEDs would remove the most problematic parts!",

[Humberto] is at it again with a NerdKits video detailing the
use of an SPI bus to communicate between microcontrollers
. He started with a previous LED marquee project which was limited to a 5×24 LED Matrix and developed a modular solution to increase the size limitation.
The writeup and video embedded after the break do a great job of detailing the important differences between a stand-alone and a modular system. The good news is that the ATmega168 chips being used have a built-in interrupt based SPI protocol. Once wired correctly, a master control chip addresses each module separately, adding data to their buffer until a full frame has been transferred, then moves onto the next module.
Some of the caveats to this system such as digital transmission over long distances are discussed. We do wonder about power limitations if all LED’s in the marquee are illuminated at once. But that concern aside, if you’re thinking of
playing around with an LED display
don’t forget that there’s usually a huge price break for orders of 500 or 1000 LEDs!

It turns out that more than just
pictures of women and flashing animations
can be found on the X10 website. [Jonathan] based
his BobLight project
around
the MS14A X10
module.
The idea for the devices started off as
a Christmas
gift for his parents in-law. A boblight turns on when motion is detected. It then communicates (through radio) with the other boblights to turn them all on. If motion is not detected by any of the boblights for a length of time, they all turn off. Rather than having the user shut all of them off every morning, a light sensor is used to automate the task.
Each boblight is a common LED utility light combined with the board of an MS14A and added
a 310MHz RF
receiver. He even hacked the board by replacing the onboard PIC with a
higher spec model
. We think [Jonathan] did a great job at implementing an innovative concept.

[Troel’s] write-up
for making your own
non-inductive graphite resistors
. Graphite resistors have the traits for being non-inductive, have a negative temperature coefficient, and
supposedly
sound better. We liked the detail of his tutorial and how he gives many examples for making your own graphite resistor.
[Thanks Maxime]

Bluetooth Based Pseudorandom Number Generation

[MS3FGX] has done an interesting study about using
Bluetooth adapters as a source for Pseudorandom Number Generation
(
PRNG
). As it turns out, the
Bluez
package has a function that calls a remote Bluetooth adapter to return a random number. He picked up 10 compatible adapters for about $30 from DealExtreme and set about assembling some numbers to see how this compares to an OS-based PRNG.
Because millions of samples are needed for an accurate comparison, time became a problem. The adapters are a little bit slow responding to a request, sending just 4800 numbers in the first 30-second test. This can be overcome with multiple adapters being accessed by multiple computers for hours at a time. What can this be used for? Your guess is as good as ours, but [MS3FGX] has done a great job of writing up his tests. He’s also made a set of 20.7 million randomly generated values available if you want to generate your own statistical analysis.

"content": "@laubeThe theory is that by pushing the calculation of random numbers out into cheap external devices, you would be less likely to be effected by a local software exploit or attack on the internal PRNG. These cheap adapters all put out the same quality of numbers and can’t be influenced by anything running on the machine. Plus they are so cheap that if one of them was showing a strong bias or had been physically damaged, you could swap it out like a lightbulb.But the idea here is not that this is a better way of generating random numbers (though it does look a little less predictable than the Linux kernel PRNG), but mainly an experiment to see if it could be done in the first place. I am certainly not suggesting anyone start doing this on their production servers.At the same time, I am working on a few true RNG projects, and this served mainly as a dry run for a lot of the concepts I will be working with. For instance I wrote up a little app (Spectra) that visualizes random ASCII files in an attempt to identify bias or repeating patterns.",

The expected probability of getting a number in the 60000-65536 range is going to be about half that of the range 50000-59999, so the expected probability of seeing a 6 will be midway between the 1-5 and 0,7-9 probabilities.(This is precisely what you see in your results)If you took the 16 bit value and printed it as 4 hex digits and then did a statistical analysis on 0-F you’d probably get pretty good results.The biases in your Interpreted Binary mode are also caused by this skewed distribution.If you still wanted to use decimal, then you should truncate the numbers from 0000 – 9999 (and print leading zeros!). If the number you get back from the device is >60000 throw it away, otherwise reduce it modulo 10000. Do not be tempted to just do modulo 10000 and use that number — you’ll just introduce bias back into your results… see the following as to why,0 – 9999 -> 0000-9999 equally distributed10000 – 19999 -> 0000-9999 equally distributed20000 – 29999 -> 0000-9999 equally distributed30000 – 39999 -> 0000-9999 equally distributed40000 – 49999 -> 0000-9999 equally distributed50000 – 59999 -> 0000-9999 equally distributed60000 – 65535 -> 0000-5535 un-evenly distributedAlso check out the analysis done on LavaRNDhttp://www.lavarnd.com/what/nist-test.html(disclaimer – I am a co-Inventor of LavaRND)",

Being avid fanatics of flashing lights, we always love to see the peggy2 in action. The video above shows another improvement, which is
two peggy2 units working together as one
. [iservice2000] chained the two together and wrote new code for the display. Using an Arduino to drive it all, he has gotten them to act as one. While
video on the peggy2
isn’t new, this is the first time we’ve seen two of them chained together. The end result is going to be a scrolling sign that can be updated via the web, or that can display tweets. We did notice a bit of tearing, is that from the camera or the software?

Capturing That (light Field) Moment

Yes, your eyes do not lie, that is
12 cameras rigged
to take a picture at the exact same moment. The idea is a single camera loses data (namely depth) when it takes a
3D image
and transposes it onto a 2D medium. FuturePicture somewhat circumvents this loss by taking several pictures with different focus distances. In short, the camera array allows you to focus on multiple items within a scene. The project’s hardware and software have yet to be released (we do know it’s at least Arduino), but they plan to make it entirely open source so everyone can experiment. Of course, we’ll keep you up to date.

We’ve spent some serious time building robot chassis and motor controllers. [Whamodyne] does the smart thing and
scavenges what he needs
form cheap sources. He picked up an RC car from the local pharmacy for just $10, tore the body off and behold, a bounty of robot-friendly parts.
We’re not talking precision parts here, but we don’t scoff at two geared motors, four wheels, a driver board, and steering. There’s no great way to attach your own stuff but that’s half the fun of hacking. [Whamodyne] used the 9v battery that came with the toy to power his
boarduino
and quickly patched in to produce a miracle of automated locomotion.

I need to look more, thanks for the tip.Add a windshield wiper motor or two and you could automate a lot of stuff, from a security cam to an antenna.",

Make An Apple Tablet Before Apple Does

[Andrew] wanted a tablet computer but is tired of waiting for Apple to come up with one. eBay and Craig’s list to the rescue, he picked up some parts and built his own tablet. You can take a look at the video tour of it after the break, or peruse parts
one
,
two
,
three
, and
four
of his work log.
The unit is assembled from a 500 MHz iBook. [Andrew] picked up a touchscreen from ebay and canibalized a USB joystick in order to add some buttons to the keyboard-less design. The end product is quite nice. We’ve wanted a tablet computer to hang on the wall for a long time and this may be the inspiration that gets us there.
Do you find this didn’t satisfy your Apple tablet fix? There’s more to be seen in
our mac tablets roundup

Clocks That Only A Geek Could Love

Alpha-Geek Clock
Oh this one’s good! This clock has a built-in WWVB receiver to make sure the time is always accurate. But with
just one LED as the display
we wish you good luck when reading it! A whole bunch of info (time, day, year, etc) is blinked out in binary encoded decimal. [Thanks Tymm]
Standard Time
Manual labor. This clock is an art installation in Rotterdam. In the
video
you can see that workers changed the segments of a four-digit display every minute over a twenty-four hour period. Since they filmed it we’d expect the ability to turn this into a video clock like
the one we saw last week
. [Thanks David]
International Clock
Low-tech but highly creative. The
instructional video
uses basic geometry and the workings from a cheap clock to craft an international clock. There are twelve labels corresponding to different time zones. Put the zone you want up and read the clock as normal. [via
Red Ferrett Journal
]
Princess and the Pea
There are few who will agree to have an air tank as part of an alarm clock. The
Princess and the Pea concept
uses compressed air to inflate an exercise ball in between the mattress and the box spring. Watch this
video
to see how it will roll you out of bed if the hissing air sound didn’t wake you first. At least it’s more gentle than the
pneumatic alarm clock
from last June. [via
Neatorama
