] | Yikes, that power connector certainly wasn’t designed by Apple. Ugly as it may be, it’s the charging cable for a robot and acts as a sensor that
allows the robot to properly align and plug into a power receptacle
.
We’re going to go off on a tangent for just a second. We often think of the
Rat Things from Snowcrash
when considering robot power. They were nuclear powered (or something) and instead of recharging required constant cooling. Those day’s aren’t exactly around the corner but we think they’ve been realized in the
lawn mowing robots
that have a little nests to recharge in. Base stations work but they require the machine to return to the same place, or to have multiple charging stations.
The point is, this specialized cable makes base stations for robots obsolete. Now a robot can plug into any outlet it can get near, a great thing for robots roving large facilities. After the break you can see a video of this process. The robot arm zeros in by scanning horizontally and vertically and measuring the magnetic field put out by the AC in the wires of the outlet. Take a look, it’s a pretty neat piece of engineering.

AVR based Tetris game that uses a TV as the display

to handle the composite video out. Using a TV takes all of the hardware work out of the equation, leaving just the composite jack and a few buttons to connect to the ATmega168 and its 20MHz clock. We’ve embedded the game play video after the break. It’s black and white but also clean and crisp.
[Ben] didn’t include music with his build but another commenter, [Eric],
has started to work on
that. We can’t help but think that
they both should have tipped us off
sooner about their projects.

stopped two releases ago
. That is to say that Team-XBMC no longer officially develops for the platform because of its inability to handle true-HD and many types of compressed content.
But, remember that this is an open source project. Just because the development team has moved on to more powerful hardware doesn’t mean the end of the 733 MHz wonder. There have been one or two folks maintaining the branch and backporting as much as they can.
It seems the that
Camelot can now run on the original Xbox
hardware. Both the skin and video playback must be set no greater than 720p to ensure smooth playback but that’s not much of a drawback considering that all video being played will still need to be upscaled to get to that resolution. There is also
a repository of Xbox friendly skin
hacks that allow newer skins to play nicely with the meager 64mb of ram available. So rejoice, you can have Camelot, and it’s crown jewel that is
the new Confluence skin

We’re not fond of going anywhere when it’s way below freezing but those professional hermit opportunities never panned out so we’re stuck freezing our butts off. Fed up with his frigid auto, [Aaron] installed a remote starter to warm the car up before he got to it. This didn’t help at work because of the distance from his office to the sizable parking lot is too far for the key fob’s signal to carry. He decided to
make his starter work with GSM so he could start the car with a phone call
.
The first attempt involved a pre-paid cell phone for $30. The problem is that anyone who called the phone would end up starting the car. After a bit of looking he found a GSM switch that just needs an activated SIM to work. When called, it reads the incoming phone number for authentication but never picks up the phone so there’s no minutes used. He cracked open an extra key-fob and wired up the lock and start buttons to the relays in the GSM switch. Bam! A phone call starts (and locks) his car.
Maybe this isn’t as hardcore as
body implants
but it’s a fairly clean solution. He uses the car’s 12v system to power the switch and pays $10 every three months to keep the SIM card active. There’s an underwhelming demonstration video after the break showing a cellphone call and a car starting.

turns any kayak into a motorized vessel that can be controlled by a quadriplegic person
using a sip & puff interface. After the break you can see some clips of navigation and an explanation of the hardware.
[Mark’s] system starts by adding outriggers to a kayak to prevent the possibility of the boat rolling over in the water. Each pontoon has an electric trolling motor attached to it that is controlled by an Arduino via a motor driver.
The Arduino takes navigational commands from a sip & puff controller. A straw in the operator’s mouth allows them to sip or puff for a split second to turn left or right. Longer sips or puffs control forward and reverse incrementally, up to a top speed of about 3.7 miles per hour. [Mark] incorporated an auxiliary remote control interface so that a safety observer can take control of navigation if necessary.
His build came in around $1300, a tiny cost if this makes kayaking available to several people each summer. Great job [Mark]!

those of us who have built projectors before
know that home made ones are usually quite large. This one is roughly the size of the small office projectors you would see in a large retailer. He’s using a 30 watt LEd for the light and we didn’t notice a lumen measurement anywhere, but it looks bright enough to be watchable.

capture 360 degree by 360 degree video
. The two cameras mount back to back and each record a 360 degree vertical view in a 180 degree horizontal range. By stitching the two recordings together and synchronizing them by comparing moving objects a seamless spherical video is produced.
He’s got one more trick up his sleeve with this setup. The tripod mount has a pivot point that allows the two cameras to shoot side-by-side instead of back-to-back. This produces a hemispherical video that is stereoscopic. That’s a pretty cheap way to make this type of 3D imaging compared to some of
the CES offerings
.
There are a few example videos up on his webpage. If you missed it earlier this month, he’s the guy that build

While most would have purchased a key-chain RFID tag, [Jair2k4] went far beyond that and
had the tag implanted in his hand
. This is an honor
usually reserved for pets
and until he adds RFID functionality to the door locks maybe a key fob would have been a better answer. But, to each his own. See his short demonstration video after the break.

He picked up the device at a discount chain for $15 and wanted to load his own videos directly from Linux without using the Windows-based software that comes with it. There’s the gotcha; even if you encode a video exactly the same as the device’s example video, it will be deleted the next time you fire up the iSee.
After some trial and error [James] reverse engineered all of the quirky requirements to load video manually. There are strict, case sensitive file naming conventions, every file must have a perfectly formatted thumbnail image, and an index file entry must be made for the video. He’s done the hard work of hammering out the details, now it should be easy to write a Python script to automatically format and copy your pre-encoded videos for use. | 12 | 12 | [

The 9-by-6 meter billboard is in downtown Moscow.
The AP is reporting
that this caused something of a traffic jam and shocked passersby. We’ve seen porn before, but have to admit that even knowing what to expect in the video it was a bit shocking for us to see cars driving by a giant sex scene. This is certainly much more of a distraction than
leaving clever messages on the side of the road

a homemade hourglass
that [Andrei] put together. The finished look is simple but he put some real time into its production.
The glass portion is a combination of two wine glasses. He removed the stems, ground the bottoms flat, then drilled holes to allow the sand to pass. He used plumbers putty around the top of the upturned reservoir to create a temporary bowl of water which cooled the glass during drilling. This prevented cracking by keeping the friction generated heat at bay. Working with the glass took a total of around five hours.
To assemble, he epoxied the two wine glasses together, routed out a ring in the wood bases for the lips, and used dowels to connect the two ends. [Andrei] concluded that the gentle slope at the bottom of the wine glasses is not the ideal shape as some sand can get stuck in them. Perhaps champagne flutes for his next build? At any rate, we think it’s a unique, non-
automated hourglass
build. | 17 | 17 | [

It may be late, but it’s a clever design. It looks sleek and it uses no buttons for an interface. [Darren] sourced the

Star Trek phaser toy with a laser added

That video shows him popping balloons with the laser, a feat made possible by the 465 mW that it puts out when the diode is driven at 320 mA of current. He’s made a nice carrying case for the weapon but we didn’t see a spot in there for protective glasses like we’ve seen with
other phaser hacks
. He did make one safety consideration by adding a safety switch and indicator LED to signal when the laser diode is armed.

giant hunk of plastic
was turning side to side and slowly waiving its arms. They said it was “dancing”. We didn’t stick around to see if it got any better. Frankly giant anime style robot ladies creep us out, more with the thought of “who is going to buy this?”.
Next time you buy a digital camera and have to explain that it’s not necessarily the amount of megapixels that determines image quality, expect to hear about this
570 megapixel camera
. We wonder if they’ve put some good optics in front of those sensors. It is cool looking, if not a bit scary. Do people smile when it is pointed at them, or run for cover?
Here’s a toy that tugs at those nostalgic nerves in the brain. It is
a quad copter that is shaped like an X-wing
. We really think this would be fun to play with. A front mounted camera would be cool. Maybe they’ll make an X-wing shell for the

While we are on the subject of Star Wars, we want to leave you with this. A

"Atmel",

] | Tetris, the timeless classic, is one of those concepts that someone will try to run on every conceivable hardware platform. I took on the challenge of
programming a Tetris clone from the ground up
using hardware I had on hand. At the heart of the build is an ATmega168 microcontroller. The game displays on a KS0108 128×64 LCD module with five momentary push switches to provide directional, rotational, and input controls. You can see the resulting monochrome action embedded after the break.
I had several goals in mind while writing the code for the game. I wanted the code to be portable so that the size of the board and type of screen used could be easily changed. With that in mind I developed
the trunk
for a Nokia 3595 cellphone screen and
a parallel branch
for the graphic LCD. Originally I was working with an ATmega8 but upgraded so that I could operate at the 3.3v the cell phone screen required.
The firmware for the graphic LCD branch compiles to just over 6 kB which means it can still be run on a mega8. Also, the ATmega168 is the same processor used in the Arduino Duemilanove so another
Tetris port
is not out of the question. I just got a hold of my first Arduino so we’ll see if I find time to start a new branch in the code.

exercise bike hooked to Google maps
. Instead of setting up a control system and writing software to control Google maps, he simply hacked a USB game controller. He wired a magnetic switch directly into the board, where the “up” button is. Then he mounted the switch so that it would be triggered each time he rotated the pedal. Though he only has the forward movement done right now, it would be pretty easy to set up a couple more switches at the base of the handle bar for left and right.
While the experience may not be quite as nice as the
more complicated one

"mythnetvision",
"mythtv",
"plugin",
"streaming",
"video"
] | Another group of developers has stepped up to the plate in the never-ending attempt to integrate online streaming video with MythTV. The
new plugin is called MythNetVision
and aims to bring streaming and downloading video functionality both easily and legally. That means without violating the terms of service of the providing website.
We’ve seen so many attempts that fell short it’s easy to be skeptical about the chances of this plugin actually working. Plugins like
MythStream
and
MythVodka
worked only temporarily before breaking and never seemed to provide a reliable option. Many people have tried adding Boxee,
Hulu Desktop
, or XBMC integration by launching these separate packages via the MythTV UI but that’s far from a clean solution.
It looks like
MythNetVision is taking a slightly different approach
. Although not yet available, the designers have built the plugin in two parts. The frontend is a fully skinnable user interface that parses RSS feeds to provide the hooks needed to browse, search, and view video. Depending on the content, a browser may be spawned to play the video, it may be played within MythTV’s normal player, or a separate download thread can be launch with video following after the appropriate buffer level is reached. The RSS feeds come either directly from the provider, such as
the Revision3 feeds
, or a scraper can be written to provide custom RSS feeds from sites that don’t have them.
We’ve seen
a glimpse of the progress
and we’re optimistic that we’ll see a reliable plugin. Early adoption and user script contribution are the best way to help ensure this so keep an eye out for the public release of this package. | 15 | 15 | [

an exercise bike controller for Xbox 360
. The controller takes pedal input from the cranks of the exercise bike. The sensing is handled by a ring of five hall effect sensors that detect a passing magnet attached to the crank. The sensor data is collected and processed by an Arduino which connects to a wireless Xbox 360 controller for output.
This version of the gaming device includes a fine adjustment widget. It uses a row of LEDs to represent the speed of the pedals and has a slider to adjust how much of an effect this has on the game. This is what we envisioned for
the trainer computer we saw yesterday
. Take a look at some game play video after the break and
dig through the code
if you have an exercise bike waiting to be recommissioned.

he figured out how to repair them himself
. The video after the break walks us through the process which starts by cracking open the case. Inside there is a controller board and a battery of ten cells. [Rob] has pinpointed these battery failures to just the first cell, which is confirmed by measuring the cell voltages with a multimeter. The first cell in the demonstration battery reads zero volts and needs to be replaced. For some reason he’s got heck of a lot of these cells on hand, at the end of the video he shows off a massive block of them that provides one half of a kilowatt-hour of power.
To complete the resurrection he removed the control circuitry from the integrated PCB. It seems that the microcontroller on the battery’s PCB monitors it and bricks them when it thinks the life of the unit has ended. By hacking a charger he can now balance-charge the altered battery packs and get more use out of them before they hit the landfill.

decided to build his own trainer computer
. He’s done a great job of integrating a lot of different data collection sources. He picked up two replacement bike computer sensors to use on the back wheel for speed (the front wheel is stationary with this type of trainer) and on the crank for cadence. He also wears a heart rate monitor and sourced a
SparkFun heart rate module
to gather that data. Finally, an LM235 analog temperature sensor was combined with a spring clamp to detect the temperature of the trainer’s resistance module.
Data from the sensors is collected with a PIC16F73 microprocessor and fed to a computer over a serial connection. He’s got a screenshot of the realtime graphs that he’s using for feedback while on the bike. This is a useful and practical setup but when he get’s tired of exercising he’s just a few lines of code from converting this into
a gaming controller

"3d printing",
"badges",
"ces",
"makerbot",
"openscad",
"thingiverse"
] | We figured we put you through enough posts about our
CES badges
without telling you how we did it or how to get one. This how-to will walk through the process of creating a badge from a dxf file for a logo. Then we will tell you where to get one.
To start with, you will need a 2D cad program, we used
QCad
. Later you will need
OpenSCAD
. Now, grab a dxf of a logo of your choice. Here, try our
logo
(R12-type dxf) so you can follow along. Open the logo dxf file in QCad.
You should now see your logo in QCad. This is nice and pretty and all, but it is not quite going to work with OpenSCAD. You are going to need to have separate layers for the separate parts. We had a layer for skull outline, face features, and a layer for each of the wrenches. Besides separate layers for separate parts, we are going to need to make sure there are no three spline points in a row as OpenSCAD will not be able to give you an stl. Plus, in this case, the wrenches won’t even touch the skull. Time to make some splines.
If you find this next part too complicated now, you can skip ahead, but when you go to “Compile and Render” in OpenSCAD, and it reads that your object is not simple, you will not be able export an STL because you get the error “Object isn’t a single polyhedron or otherwise invalid! Modify your design..” you will have to come back to here to fix your splines. Turn off all layers except for the one you want to touch up. Make a new layer to replace the old layer. Name the new one new_foo or rename the old one to old_foo. However you do it, keep it clear and this will be much easier. Now, highlight the old layer, you should see the points used to create the splines. Set your snap to endpoints (Snap -> Endpoints) and start drawing a spline (Draw -> Spline -> Spline). Pay attention to the cursor information in the lower left of the window. If you have three spline points along a line, OpenSCAD will not like it, so you will have to alter your spline slightly by skipping the middle of the three points. How do you know if you have three spline points along a line? Well, for the most common case in grid-drawn splines, it is when the x or y coordinate does not change for three points in a row (ie a spline with points: {(1,1), (2,1), (5,1)}, the y-coordinate does not change). Straight lines may also have a problem, but there is not much of a reason to make straight lines out of many straight lines.
Each part of the logo with it’s own color for clarity. Save a copy of the dxf as an R12 dxf, OpenSCAD likes it better. Now, let’s make it three dimensional. Start OpenSCAD and have the
OpenSCAD User Manual
up in your favorite web browser. Here is the final code to get the whole thing working, copy and paste it into OpenSCAD:
logo_offset = [-104.281, -142, 0];
logo_scale = [0.65, 0.65, 1];

Hit F5 to do a compile and you should get a rendering of the Hack a Day logo in the upper right of OpenSCAD.
The logo_offset and logo_scale variables will center and scale the logo. The value for logo_offset depends on where the center of the logo is in the dxf file.
The union() will make all of the things in its brackets one thing.
The scale()s you see will scale the things inside their brackets by a certain factor based on the passed vector.
The translate()s move the things inside their brackets an amount determined by the passed vector.
dxf_linear_extrude() is like a play-dough factory, it extrudes a shape based on the passed information: dxf file, layer, and height. The center variable determines if the extrusion is centered at z = 0 ( center = true) or if extrusion starts at z = 0 (center = false). The convexity variable seems to look ugly at low numbers.
The intersection() makes a thing from two intersecting things inside its brackets.
The difference() takes the first thing in its brackets and removes the rest of the things in its brackets from the first thing.
Sphere() makes a sphere of the passed radius.
To help you visualize this process, disable all of the dxf_linear_extrude() and sphere() lines by putting an asterisk (‘*’) in front of them.
Remove the asterisks from the first two dxf_linear_extrude() and compile to have OpenSCAD union, scale, move, and extrude the wrench layers of the dxf. This should yield a pair of crossed wrenches:
Let’s add the skull outline by removing the asterisk from in front of the third dxf_linear_extrude() line and compile:
Replace the asterisk from in front of the fourth dxf_linear_extrude() line with a pound (‘#’) and compile. This pound symbol will highlight the thing it is in front of in pink, helping you to see where it is and what it is doing since you normally do not see it because it is being removed from the skull.
Remove the pound symbol, compile, and you will see how the eyes and nose are formed by the removal of the dxf_linear_extrude() of the face layer from the dxf_linear_extrude() of the skull layer.
Replace the asterisk on the first sphere() line with a pound symbol and compile.
Depending on you viewing angle, you may not see the pink sphere appear within the skull. Click and hold on the image and move your pointer up. The object should now rotate with your pointer until you let go. Rotate it around to see the back of the skull.
This should help you see that the first sphere is still within the difference() and was thus removed from the skull extrusion. Remove the pound symbol from the first sphere() line and compile. Notice that neither the eyes and nose extrusion or the sphere() removed anything from the wrenches. This is because the wrenches are outside the difference(). It helps to keep things hollow as printing the object will use less material and you can do things like this:
Putting an LED inside the skull would have been difficult without making the skull hollow. Plus, where would the brain go?
The way it is now with a flat face is okay, but it would be better if the skull had a more rounded appearance. Remove the asterisk from the last sphere() line and compile.
The skull now has a rounded face. Inside the intersection(), we created the difference() that created the skull with the flat face and a sphere. You can see the sphere by putting a pound symbol in front of it and compiling. The intersection() makes an object only where both of the parts are at. You can see this even better by putting a pound symbol in front of the difference() and the last sphere() line.
So, how can you get your hands on one of these things? We can think of a few ways to get one, but the best two would be to either make one or have one made for you.
If you have access to a 3D printer, you can make your own. We used a
MakerBot
CupCake CNC. The files to make your own badge are on
Thingiverse

Boy, EPROM really suck. But so do pacifiers and he already had a solution for exposing those to UV. He pulled out his $30
UV pacifier cleaner and tossed the chip inside
. Two times through the cleaning cycle and the data was gone. We’ve looked into using UV LEDs to do the job but
some experimentation
shows that it doesn’t work. These pacifier cleaners are cheap and easy to get a hold of. The real question is are you still using chips that require UV for erasing? | 60 | 50 | [

] | If you’re into embedded clothing this
stroke sensor
is for you. As demonstrated in the video after the break, stroking the threads in a particular direction will create a circuit that senses and, in this case, turns on an LED. The concept uses two conductive buses on the back of a piece of neoprene. Conductive and non-conductive threads are then added for a furry or bristly finish. When stroked perpendicular to the power buses the conductive threads come together and form a circuit.
For some reason this just seems a bit creepy to us but perhaps that’s only because we haven’t come up with the right application for the technology. We’re pretty sure that a sweatshirt with an
LED marquee
and a “hairy” back that you stroke to illuminate is the wrong application.

Potentiometers used in circuit bending allow for
manipulation of the sounds coming out of the circuits

In this case the pots are connected to the microcontroller instead of the sound generation circuitry which means you can do whatever you want with them depending on how creative you are with the code. So far he’s just starting to get the new set of interfaces to play nicely over the serial connection. This could end up being quite popular as it only requires the addition of a multiplexer IC, the potentiometers, and the knobs. | 10 | 10 | [

can be hijacked for dubious purposes
. The frame can add Internet content as widgets; things like Facebook status, tweets, and pictures. The problem is that the widgets are based on a feed from a website that was publicly accessible. The only difference in the different feed addresses is the last two characters of the frame’s MAC address. Feeds that are already setup can be viewed, but by brute-forcing the RSS link an attacker can take control of the feeds that haven’t been set up yet and preload them with photos you might not want to see when you boot up your factory-fresh frame.
It seems the hole has been closed now, but that doesn’t diminish the delight we get from reading about this foible. There’s a pretty interesting discussion going on in
the thread running at Slashdot

The camera was capable of using the separate cameras in different functions, allowing you to zoom one in, and take a wide angle with the other simultaneously.
They featured a miniature 3D display as well, which was the size of a regular digital photo frame but contained the same technology as the camera screen. As far as getting into hacking a 3D display, this would be a good place to start, though the ~$400 price might be a bit of a put off. | 22 | 21 | [

I got my hands on a set of augmented reality glasses that were displayed with a Monkey-Ball style game. This wasnt anything too new as far as the augmented reality goes, however the glasses that were used with the game featured stereo cameras on the center of the outside of the lens, which allowed a true 3D augmented vision that you wouldn’t have to stare into a screen for. These glasses were still in the demo stage, but if they ever make it out into retail, I think that they would be exactly what could bridge AR from a fun toy to a useful tool.

previous post
we had given one of our badges out to [
Bre Pettis
] at the
MakerBot
booth. We have been called the “Skull Guys” around CES and were stopped multiple times by people that did not know of this site. [Bre] got an extra of the size we are wearing around. [
Leo Laporte
] received the very first prototype which he
promptly placed in his mouth
. The badges are made from natural ABS plastic in [Devlin]’s CupCake CNC machine. There will be a post-CES follow-up with the release of the STL files to make the badge on
Thingiverse
as well as a step-by-step breakdown of the build process. | 8 | 8 | [

"News"

"ces"
] | We really really wanted to see this system. It supposedly created a 3D projection in the air. They didn’t have a system on the floor, but invited us to their hotel room for a private showing. We did manage to find the room and were welcomed in to the sight of a smaller unit that made a roughly 4×4 inch projection inside a cylinder.
It was truly 3D. It was not the old angled glass trick. They would not let us take pictures, or video. The guy wouldn’t really answer any questions at all. We are speculating that it was just intersecting lasers. You could clearly see the vertexes, as you can see in the pictures above and there was a scanning refresh effect that was visible to the naked eye. We really wished we could have seen the big unit that projected into the air instead.
Edit: One of our readers managed to find a video of what we were talking about, thanks [alex]! Video after the break.

to show off a zero wire concept. Sure, the giant 2001: A Space Odyssey looking monolith behind it is a bit imposing, but for something that could be embedded into a wall, we’re pretty impressed. Wireless power is a big thing here, and we cant wait for hackers to
take up the reins

looks like it could actually be a useful tool. We’ve seen several people
make glove
input devices over the years and this looks like a quick and easy way to get one going. It touts over 30 touch points that are user programmable. Really, it works more like a keyboard wrapped around your hand than any kind of motion or flex sensing. It could probably save you some time if you are headed that direction, but at $250 you might just want to build your own.
[James] – For those looking to make your own, Adafruit offers both
flex sensors
and
force sensitive
buttons that could help you work on something like this. | 8 | 7 | [

complete hardware emulation of the Atari ST using an FPGA

EmuTOS
, an Atari emulator, as the operating system because running the original would violate copyright. The chip used is an Altera Cyclone III. You could load up the code on your own hardware but judging from the number of connections needed it might be less of a headache to buy a board from these guys.

She hot aired off the bad chip implementing an “Impenetrable Aluminum Heat Shield of Science” to protect the rest of the components. In the chip’s place she soldered a wide DIP socket for which the NES engineers had thoughtfully left a place. Then, using a 128Mbit SRAM SOIC, she soldered it to 0.100″ headers to fit in the socket. As the original chip was only 16Mbit, unused address lines are tied high or low. The console is now fully functional again. Also checkout the comments on

an Etch-a-Sketch interface

A video of the CNC machine can be seen after the break. He needs to add a frame to increase the precision of the images drawn but this first attempt is pretty good. We prefer to have the computer in charge of the design because
controlling an Etch-a-Sketch with a mouse
doesn’t make our drawings any better.

[TheGrue] has put together this
great writeup on how he built TOBI, the tool carrying robot
. Inspired by a story he read about a robot that could follow people around, using heat sensors, he decided he wanted to do something similar. His robot would carry his tools, in this case, the tools of an IT professional. Not only would it carry his tools, but surely it would give him credit as a techno-guru to have a scratch built robot following him around.
His build process is documented quite well. He approached this in a fashion where he set several iterations. Each step would add a feature and carry the old features forward. It looks as if he’s currently working on step 3, which means that the chassis has already been built, the drive train is working, it can be remote controlled, and now has some level of autonomy thanks to a propeller controller. Up next are some range finders and an assortment of other sensors so that TOBI won’t drive off any steps, or into any walls.

As seen the video after the break, the Ericfon works the same as it did when it was new, except the connection is made through Bluetooth and not via a copper phone line.

The design for the box pictured above is not new.
The plans
for the Cubey 2 project have been around for a while but relied on your mad-woodworking-skills to turn out the pieces. Since we’re not great with a chisel we were happy to see vector graphic and encapsulated postscript files to robotically aid in production. Once the puzzle parts have been assembled a facade is adhered onto each side to hide the pieces. This means you can go for Higgins’ traditional puzzle-box look or sport the

He cracked open the case to find just a few components. The brain behind the IR signals is a Helios H5A02HP. Only a few pins are used for outputs so he connected a logic analyzer and recorded the signals. His writeup covers the process quite well. He takes a known IR transmitter protocol and compares it to the capture from the logic analyzer. It turns out that the fob generates 46 different signals and with further analysis concludes that there’s a chance the code used here is from an older version of the TV-B-Gone source. | 17 | 17 | [

[Mike] is
building his own Pulse Oximeter
which uses light to measure the oxygen saturation in blood. One collateral benefit of this measurement is that pulse rate can be calculated from the same data. The
parts used for the detector
include a red LED, infrared LED, and a TSL230R light intensity measuring chip. As explained in the video above, each LED is shined through the tip of your finger and onto the light sensor. The IR LED is used as a baseline and compared to the red LED, which has some of its intensity absorbed by the red blood in your finger. This is a pretty approachable biometric concept so you may want to start here before moving on to
more involved biometric interfaces
.

compiled his findings

we covered it in November
and picked up a couple to see what he could do. He patched into the debug port in the CC1110 processor and enabled it by performing a chip erase. He then began mapping out how the processor connects and communicates with the qwerty keyboard, the wireless radio, and the LCD screen. The board is full of test points which make the hardware easy to access. [Dave’s] experiments show that this hackable device is full of potential so let’s see what you can do! | 13 | 13 | [

Arduino to perform various I/O operations
. Predictably,
analogRead()
takes the longest, followed by
analogWrite()
. Arduino really falls behind when it comes to digital pin I/O:
digitalWrite()
takes a whopping fifty times longer than a direct bit write to a port register! This is something to take into consideration when you are looking to do some beefy I/O with an Arduino. Perhaps this I/O performance will be addressed in the future with
Arduino 1.0

] | [Nophead] started the year off by
successfully extruding acrylic
using a RepRap machine. The problem when working with this material is that when the hot ooze hits the cold air the printed material tends to warp, badly. [Nophead] raised the ambient air temperature around the part being extruded by replacing the bed of the RepRap machine with a heated aluminum plate.
We took at look at his
build details for the hotbed
. The plate itself is aluminum that he had milled by a machinist friend of his. It looks like the heat is produced by a network of power resistors bolted and soldered to the bottom of the plate. The original idea was to produce a controllable SMT soldering platform. Unfortunately this heating method doesn’t have the power needed to raise the temp quickly but that failure turned out to be a RepRap success. | 16 | 16 | [

"candle",

"peltier cooler"
] | What you see above is a generator that converts heat to electricity. [Reukpower’s]
thermoelectric lamp
is one of those hacks that makes you scratch your head even though you understand why it
should
work. The heart of the system uses a Peltier cool, just like the
thermoelectric solar generator
. When there is a temperature differential from one side of the Peltier to the other a small current is generated.
In this case a candle heats one side and a heat sink cools the other. The tiny voltage picked up from the Peltier’s contacts is then boosted using a joule thief. We’ve seen
LEDs powered with a joule thief
before, benefiting from their own low power consumption. In this case, the boost circuit is scavenged from an emergency phone charger and probably achieves higher efficiency than if he had built it himself. | 67 | 50 | [

"classic hacks"

"display",
"paint",
"phosphorecent",
"POV",
"record player"
] | At first glance we thought
this record player
had been modified to serve as a persistence of vision device. The device looks very much like an unmodified turntable but it has four tracks worth of display space in it. The messages are actually glowing and don’t depend on a POV effect. Instead, the table has been coated with phosphorescent paint that will glow after being exposed to bright light. The needle has been replaced by a small PCB with downward facing LEDs on it. A microcontroller pulses the lights to expose the paint in patterns that make up the messages. This is the same concept we saw with
the Ghost Matrix
but this iteration is silent, and the control circuitry is less apparent.
The video after the break is a must-watch. The 60 character long messages are beautiful to watch rotate into the display. Unlike
a POV display
, ambient light will greatly interfere with the effectiveness of this method. That being said, what a wonderful party decoration this would be if mounted on a wall in a rather dark room.

an update on his traffic light hacking
. Dedicated readers will remember seeing this legally attained
traffic signal controlled through a parallel port
from back in 2005. The new update swaps the old port for USB and adds several autonomous functions which are demonstrated in the clip after the break. The update includes a nice UI and some notifications for things like email, IMs, Reddit posts, etc.
He’s given control of the hardware over to an Arduino. Instead of building the board into the project he’s included just the parts he needs; an AVR running the Arduino bootloader, a crystal and filtering caps, and an Arduino serial to USB module for connectivity. The AC load switching is handled by three relays. The relays he links to are 12VCD rated coils. We think this should have pointed to 5VDC coils as that’s the voltage that the logic circuit are running at. Be careful with switching these AC loads,
this traffic light isn’t a toy
