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.

The robot would look for the pattern of the wall sockets in the image it would acquire and then home in on the socket and plug itself in. Quite clever for its time.

It gets the plug into the right area, and then keeps tapping it around at different offsets until it gets it right. Sometimes it’s quick, sometimes it tries for forever to make it right.This sensing system, while as described appears quite slow, was bang on accurate on the first try. I’m not so happy seeing a large copper conductor surrounding all three pins on that plug however. Sure it’s almost certainly safe, but the potential to have it short against one or more of the pins seems like a danger to be avoided in my opinion. Could they have achieved similar sensing results with just a ring around the exterior or using all three pins at once for the coarse measurements?",

He should have looked at the code and seen that recepticals all need to be mounted at a certain height and certain distance on a given wall. then take a picture of the wall look for the contrasting areas and you should be able to find the switch.

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.

"content": "Thanks for the feature!Benny M: Very observant. ;-) I have a VGA box hooked up to my monitor. One thing I haven’t worked out yet is why I get colourful rainbows around every black-white transition when viewed on a TV tuner or VGA box (easily fixed by switching the saturation right down) but no such effect on the handful of “real” TVs I tested on (crisp black and white from the start). Maybe real TVs can detect a black and white signal better than a TV tuner or VGA box?Agent420: You can get decent colour out of an ATmega168 if you output RGB (seehttp://avga.prometheus4.com/index.phpfor an example) but as I only had access to an old TV tuner and VGA box, both of which only support composite or S-Video, I kept it black and white. You can get RGB to composite/S-Video ICs, but they were pretty expensive when I looked. I did also look into Propellers some time ago, but hastily closed the tab when I saw that they were going charge around $50 to ship to the UK!Nemo: I did a rough test by counting the number of frames it took for a _delay_ms() call to execute, and estimated around 3 MIPS. After enabling TVTEXT_SKIP_ALTERNATE_ROWS I estimated around 9 MIPS. These weren’t very scientific tests so could be completely wrong, but there’s more than enough CPU time left to run a C implementation of Tetris smoothly. (I’m using a 20MHz clock).",

[Drew] wrote
a library for playing multichannel music on an Arduino
. The project connects multiple piezo buzzers to the popular prototyping platform and handles the dirty work involved in modulating multiple buzzers at the same time. The video above starts with an explanation for the first three minutes but if you’re impatient you can
jump directly to the music demonstration
. The results are magnificent. We’re going to
check out the code
and see what we can make happen just as soon as we can round-up multiple piezos.

XBMC On Xbox Keeps Going And Going

It’s no secret that XBMC just saw a major release with version 9.11 Camelot. What many don’t know is that development for the X in the name (Xbox)
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
.

It is a rare thing to be able to get so much functionality out of a device that can now be had for almost nothing – I’ve gotten two for free off of my local freecycle.My first xbox has been modded since 2003, and I have used XBMC as my main dash since 2005.I can’t think of any electronic device I have ever owned that has held up as well as the original xbox in terms of its continued usefulness.It started out as a great platform for playing ripped xbox games, then there were the emulators that enabled me to play every console from my childhood on a big screen with a good controller, then there was XBMC which was and is probably the best media platform in existence.In the early days, there was nothing that could compare. The xbox was an ideal living room computer. It was relatively compact, could boot up in seconds — even had a remote! It was a far more elegant solution than plugging a laptop into the TV, and did so much more.When I started out, I put the biggest IDE hard drive I could afford in the xbox, and filled it to the brim with joy. These days, I don’t even need to do that, as the Xboxes on our TV’s flawlessly stream media from a home server.I’m happy to see XBMC thrive on other platforms, and happy to see that there are now devices available commercially that do what I’ve been doing with my xbox for half a decade. But the xbox still does everything that I need it to, and does it impressively well.Is it still worth it? Hell yes.",

(well, DVD’s if you got the DVD playback kit) First you have to mod the xbox (variety of methods) to enable installing non-authorized software, then you have to install XBMC. XBMC is very good at playing all kinds of video files. I used to laugh when windows media player on my computer choked on almost every type of video due to missing codecs, but XBMC virtually never did, even if the video were in an ISO, BIN, or RAR.XBMC makes the xbox a more versatile media player than the xbox 360. Only weak point is that it doesn’t have the processing power to display native HD video — although with the right cables it will upscale SD content to 720p or 1080i, which works very well. Lack of HD might be a deal-breaker if you’ve got a massive TV, but SD content is perfectly watchable on my 32″ samsung, and the video files are a fraction the size.",

Already some custom dashboards for the 360, emuators running, ability to play installed games off the hard drive without the disc, etc.If you have an Xbox 360 with dashboard version 7363 or lower (versions 8xxx and higher don’t work), you can mod your 360 just like the xbox 1 days. It’s still in its early infancy though so the really good apps are still yet to come, but it is an awesome achievement!",

It hurts us to look at this quadcopter, agonizingly so when we watch the video after the break. That’s because we feel the unstoppable compulsion to build one. This
four-rotor helicopter
has a lot to be proud of; it features Gyro stabilization, Xbee remote control for very long distance operation, and computer interface for data graphing and calibration.
We like the
quadcopter that we came across at CES
but building one of our own is more fun than buying it ready-made. The pain we’re feeling is mostly in our pocketbook. To help ease the agony we scoured the
parts list
and the
assembly instructions
in order to get an estimate of
what this might cost
. We’re looking at around $415 plus shipping, not including transmitter and receiver for controlling it. Yep, that’s a sharp stabbing pain but we’re not sure we can just let it go.

Integrating the motor controllers and battery monitor will save another $44.I know this doesn’t take into account the components needed to populate the PCB, but they’re most definitely far less than $150. Pretty much everything can be sampled for the prototype.Not to criticize the designers for the lovely proof of concept made from off the shelf parts, but there is room for vast improvements and cost reductions.",

It seems like the whole control board price could be cut down significantly if you were willing to put a little effort into the build. Plus if you had access to a plasma cutter, you could use Nicholas’ idea and cut your frame from fiberglass (or carbon fiber in his case) it would be very inexpensive. The only cost that is more or less fixed would be the motors and batteries.All of that being said, my budget doesn’t even want me to look at this project anymore for fear of not eating.",

It’s just starting to warm up around here but it was very cold for a long time. 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.

"content": ">And, problematic for mechanics (more so than the RFID guy’s car)Why? I’d think that this makes it actually easier – if the car can be started with different cell numbers (it doesn’t have to be cellular) then he could just add the mechanic’s cell number to the list and revoke it later. That’s actually more convenient than keys, which a mechanic (or anyone else) could lose.Lent your car to a friend? Temporarily add their cell number to the list and they can start it too. Much less of a hassle than getting keys cut orI like the RFID idea better for security purposes (it’s harder to fake), but this is interesting for convenience (the ‘key’ is easier to share).Also, I’ve not seen anywhere where it was said that the traditional mechanism (key on the steering column) for starting the car was removed – this system could just have been installed in addition to that.What might be an interesting blend would be if the car could be started by remote with the cell, but could not actually be driven until the key was put into the ignition (it would just cut out). That way one could have the benefits of remote starting without the threat of theft.",

A Day At The Lake For The Disabled

We do a lot of useless hacks just for the fun of it so when we see something with purpose it’s pretty exciting. This hack
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]!

[Newtonn2] dropped a tip in our inbox this morning that made us quite happy. This is a
step by step build of a small form factor LED based projector
. While the size may not get some of you too excited at first,
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. Pictures usually turn out dark, so in person, the projection probably looks more bright and crisp. Now he just needs to find a high definition LCD that size.

Sure, if they made their own content, like, say, makezine, sure, they’d have every right to lock people out of it and make people pay to view it.. But taking people’s CC and GPL licensed works, claiming ownership of it, and locking everyone out of viewing it unless they pay, is, I think, contrary to the whole spirit of their site. They also censor anyone who mentions anything about this, and they bribe authors to remove negative comments, either financially or by offering them better placement on the front page.Sorry, it looks like a very nice projector, and I’d love to know how it was made, but I cannot click the link.",

Spherical And Stereoscopic Photography

[Ryubin’s] experiments with spherical video continue. This time around he’s using two cameras, both with fisheye lenses, to
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
a spherical video setup using a light bulb
.

Start The Car With A Wave Of Your Hand

[Jair2K4] likes his RFID almost as much as he likes his chaw. Ever since his car was stolen he’s had to start it using a screwdriver. Obviously this is not a good way to leave things so he decided to
convert his starter to read an RFID tag
. He installed an RFID transponder he picked up on eBay, wiring it to the ignition switch. He’s removed the clutch-check sensor and wired a rocker switch to enable the RFID reader. We presume the rocker switch will eventually be used to shut the car off as well.
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.

I did a lot of research into the safety aspect before hand, and the device I implanted has FDA approval (although for bicep implanation rather than in a hand).It’s perfectly safe for MRI scans, it’s so small and has such a tiny amount of metal it isn’t going to move or get pulled out etc. It doesn’t generate radiation, it modulates the signal sent by the reader (which you would be exposed to holding a tag in your hand), and there are far greater electromagnetic waves around us that haven’t been shown to cause harm.As for tracking, they are very small and work at 125Khz which means they have a very short range. The reader has to be within a few cm’s of the chip to read it, so you couldn’t just walk into a room and get scanned. They also feature encryption which can be used if desired. Also, how would anyone know you had an implant to be able to scan you?The implants have been used in animals for over a decade and have not been found to cause harm. If a risk does come to light the chip is very quick and easy to remove.It’s not for everyone, and I have my own reasons for doing it – some people think i`m mad, others are fascinated by it, either way it’s an interesting talking point :-)",

We would imagine these experiments were spawned by a devastatingly boring day at the office. [Sparr] found himself the proud owner of one thousand rare-earth magnets and
decided to see what geometric shapes he could build
with the spheres. These are gold-plated N35 Neodymium magnets that measure just 6mm across. He discovered that every structure is built from rings of magnets with shapes dependent upon what sequence of increasing or decreasing members are used. What he’s done is visually pleasing but we’d like to try it ourselves to see how resilient each structure ends up being.
[Sparr’s] post is from the
Freeside Atlanta
blog, a hacker space collective. [Curbob], a regular with the group, tipped us off that a few hacker conventions are coming up in their area and
they’re looking for speakers
for one-hour talks about projects. If you’re near Raleigh or Atlanta this is your chance to show off that
ridiculously complicated project
you’ve been risking your marriage to complete.

From the pictures, a ring of five will give you a gentle corner. And a ring of 4 will give you a steeper corner. A ring of 3 will just end up like a ring of 6 if you can get it to hold.

IPod Peripheral: ISee360i Hacking
|
Mike Szczys

[
"ipod hacks",
"Linux Hacks"
] |
[
"iSee360i",
"video"
] |
[James] has done some work
reverse engineering the protocols for the iSee360i peripheral
. This iPod addon is a media player housing that features a 3.6″ screen. It can be used to play video on iPods that don’t otherwise have the capability because it just uses them as a hard drive. 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.

Russian Billboard Includes A “happy Ending”

It seems someone hacked into one of LED billboards and added porn video clips to the rotation of advertisements. We caught a glimpse before YouTube yanked it. We’ve pixelated the shot above which already had some blackbox censorship from the OP but we assure you, it was hardcore porn.
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
.
Does anyone know what technology is used to update these billboards? We’re curious as to whether physical access to the unit is necessary for this kind of attack. Leave your insights in the comments.
[Thanks Sean]

For how expensive and more advanced they are over your run-of-the-mill billboard, it sure would be nice to be able to remotely update the sign. I bet in my case, the arena does the updating, since most of the time it shows upcoming performances and sporting event dates.",

We’ve seen a glut of time-keeping projects lately. We guess time was the original motivator for technology so we’re okay with it (but we’re not calling ourselves Clockaday quite yet). This clock, or more appropriately this timer, is
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.

Volt Meter Clock

The
Volt meter clock
continues our recent slew of interesting clock projects. Though considerably easier to read than the
resistor clock
, it is in the same frame of mind. Set up to look like the face of an analog volt meter, it almost looks like something official or scientific. Since [Jon] couldn’t simply drop a clock mechanism in, he used a PIC microcontroller. The circuit is pretty simple, but he deserves some credit just for the unique layout.

Anyone who is familiar with animatronics or even most robotics knows that almost every build is a hack if you don’t plan on reproducing it. This gallery is to show off the work of [John Nolan]. However, instead of just posting the final product, he has posted several galleries that show, in detail, the internal structures. Curious how to rig a jaw or an eyebrow? Wanna see the internals of an animatronic baby? How about building giant monster hands that are rugged and have full digit control? It’s all in
the gallery

. Well, it really uses a model of a resistor. This extremely tardy entry in the
Hackaday design challenge
houses all of the electronics on a PCB the size of a business card. Four RGB LEDs shine up through holes in the wooden base to light bands on an acrylic tube. The colors correspond to the values used in the
Resistor Color Code
. In the picture above the clock is displaying 5:26 (that’s supposed to be a red band but the camera didn’t pick it up too well). The band in the center fades up over 60 seconds to signify AM, and down to show PM.
It may be late, but it’s a clever design. It looks sleek and it uses no buttons for an interface. [Darren] sourced the
LEDs themselves as light sensors
to display the date, and enter time setting mode.

Here’s another
Star Trek phaser toy with a laser added
. [Jay] started with a 1994 Star Trek phaser and added a 12X Blu-Ray diode. The sound effects of the toy still work, a nice touch that you can check out in the video after the break. 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.

We saw this
home made beekeepers hood
posted and actually mistook it for an art piece. We thought it was a Super Mario squid. You can see an example on
this image
, which is located on a site dedicated to
cross stitching video game characters
.
In an odd coincidence, not related to the 8 bit textiles above, we also found this
Mario themed sweater
. We wouldn’t wear it, but we’d love to see
Wil Wheaton in it
.
No. No no no.
Bad Scientists
. No treat for you.
There are 4 more links after the break, you’ll want to see them to get that baby out of your head.
[youtube=http://www.youtube.com/watch?v=SaHnAU4uPHk]
We actually saw this one in person at CES. This
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
AR. Drone
.
While we are on the subject of Star Wars, we want to leave you with this. A
Star Wars themed burlesque show
opened in L.A. recently. Who knew those storm troopers were so sexy under those suits of armor? They do mention that there was a “sexy Jabba the Hut”.

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.

Google Bike Hack, Quick And Dirty

Many of the projects we post are so well thought out and engineered, they could hardly be called “hacks”. This one, however, falls neatly into the hack category. [Dave] wanted his very own
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
, aside from head tracking, it isn’t that far off.

[Julien] let us know about his
ProtoDeck
. A MIDIBOX based controller for Ableton Live using a Big Max for live patch interface.
One thing that we have seen is
less and less hacks
for are
MIDIbox projects
. It is no wonder, considering now a days we have
touch screen
and multiple other interfaces and sound creation tools – MIDI almost seems like a dying art.
The ProtoDeck uses 87 pots, 90 buttons, and 81 RGB LEDs all controlled by 2 PIC 18F4620s. [Julien] says his main goals where to have lots of color and buttons. We think he succeeded.

Tricking An IPod Into Trusting Your Dock

[Thijs] has an iPod dock with an LCD display in it that allows you to watch videos without having to squint quite as much. Unfortunately, the iPod classic wouldn’t play videos on it because it’s not an Apple approved product. He figured out that an authentication chip is included in docks and cables that Apple has approved and
set out to retrofit his device with one
. He pulled the PCB, authentication chip included, out of a $5 cable from Deal Extreme and wired it up to the PCB on his dock. Voila, the dock now plays video.
This is a nice hack but it’s also just silly. You paid for the iPod, you paid for the music and videos (right?), and you paid for the dock. Why can’t they all talk to each other without authentication?

Since she now uses iTunes she doesn’t have to worry where the content comes from or how to transfer it. Apple is very restrictive in this process to make it easy for people like her to do this.Most people don’t care about “locked down outputs, low compatibility with nonstandard formats, App-store approval requirements, etc.”It plays MP3s and AAC which is what most non-technical people use. You can walk into pretty much any retail store and buy a cable or dock for the thing which is convenient for most people. The vast majority of people aren’t phased by the app store and find it convenient to have one place to get everything, even if Apple has more control over it than us in the Tech work would like.Apple isn’t making devices for people who like to tinker and play every format under the Sun. By limiting the features of a device to just what is needed, Apple can spend a ton of time polishing the device and make it as easy and pretty as possible.“I’d like to see a competing device that is DRM, protection, lockout free and supports more formats while still having a good dock system like the iPod.”There are tons of MP3 players out there that fit most of these requirements.

I installed iTunes on my laptop & got the iPod ‘working’, the install force installed QuickTime (which I CANNOT STAND).After getting the 3rd party software working with the iPod I uninstalled iTunes & then QuickTime – this killed the wifi drivers on the Asus Eee, it took TWO re-installs of the wifi drivers to get it working again, and now everytime I take the laptop out of StandBy one of the background Asus programs for accessing the laptop’s specific hardware crashes.The iPod now sits permanently blu-tacked to my monitor as a reminder to never be curious about Apple products ever again.

Things like being able to take pictures and video. I had that on my MP3 player in 2001, and for 2001 it was a pretty decent camera – for 2010, the nano’s camera is pretty crappy. Oh, and even back then they managed to figure out a more ergonomic way to hold the damn thing while using the camera. Hell, things like flash memory even, which was how most of the very earliest MP3 players worked, was somehow some huge revolution when the nano came out. Oh, and do they have custom equalizers yet? Because I had those on MP3 players back about 10 years ago too.Pretty soon they’ll be selling a nano that uses an SD card and talking about how it’s _absolutely amazing_ that you can _change your entire library_ just by switching cards!The only new feature Apple has ever put on one of their iPods is the scroll wheel – and possibly the touch screen, though I think those may have been done before too. They weren’t the first with a hard drive MP3 player, they weren’t the first with flash memory, they weren’t the first with color screens, or with video, or with a camera, or with radio, or with tiny MP3 players, or with tiny MP3 players without a screen, or with that music library navigation system (I had MP3 players before the iPod that not only created a music database so you could sort by artist/album/etc, but they also did it without the use of any computer software – you dragged and dropped onto the device and then it created the database. Hell, I had CD PLAYERS with databases!), and they weren’t the first with apps. They aren’t the most durable, they aren’t the highest quality, they aren’t the cheapest, they don’t have the best UI.

They did this for music now they should have finished the job with video but instead gave in to the studios’ whining, same with all the stupid corporations who gave the studios HDCP and Blu-Ray and CSS and all the other bad technologies that have plagued distributed media in the past.

It should be enough to say that unlicensed accessories that damage your product void your warranty, this is common (Nintendo did it for sure, they used to slap a shiny Seal of Approval on everything that they wanted you to use and people tended to buy the approved stuff).

MythNetVision To Cure Borked MythTV Hacks
|
Mike Szczys

"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.

Bike Controller For Xbox 360

"xbox 360"

ProjectExciteBike is on its second iteration of
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.

[xellers] may have been in 8th grade when he
built this vacuum tube tesla coil
, but he did a fantastic job. Unlike most of the tesla coils we have shown, this one doesn’t use a high current transformer from a neon sign. Instead, he’s gone the direction of vacuum tubes. He spent a total of about $125 which isn’t too bad. Most of us could reduce that cost by scrounging from our parts bin.

The Russians are in fact more advanced than the Americans which they demonstrated when they opened up a spiral in Norway’s skies right on the eve of Obama’s Nobel Peace prize. American scientists were quite angry at the fact that they are behind, but this is how the controllers, the so called Committee of 300 wish it to be.For decades, the Russians have been in possession of Cosmopheres that can travel to Mars and further. They have built underground cities in the Moon and Mars but the USA cannot do anything about it, for it has been subverted since the creation of the FED. Those who control the money flow control government. As Harold W. Rosenthal, the Administrative Assistant of Senator Javits of New York, in 1976, revealed in a public interview: “Roosevelt was our man…since Roosevelt the United States government has been under our control.” Harold explained that by controlling the Media, schools and churches that a false reality can be created quite easily. Remember Orson Wells story he told the American public through his radio show one day? And how he created such fear and panic just through the Radio airwaves?Our history is full of inaccuracies, or lies, for the news service was always of great value to the Talmudic Babylonian financiers, as Rothschild demonstrated when he got hold of news about the result of the battle of Waterloo before everyone else.",

Stare at [Luke’s]
LEGO router case
; STARE AT IT! The router is nothing special, a WRT54GL that is fun to hack. We’ve seen it
used as a robot
, turned into a
war driving box
, and obviously this is where
dd-wrt custom firmware
started.
[Luke] designed the case in MLCAD and found a seller for the parts which came in just over $50. We think it’s much better looking than the stock case an
if you used that for a different project
, this is a way to replace it. We’ve embedded [Luke’s] assembly video after the break. If you like this case, take a look at
his LEGO PC case
as well.

Neon Lamp And Other Crazy Clocks

"neon lamp",
"nixie",
"vacuum tube"

Quick quiz, what came before transistors? Why
vacuum tubes
of course. If this clock doesn’t make you thankful for the luxury of integrated circuits, nothing will.
We had never heard of using
Neon Lamps as logic circuits
, and they definitely produce a
much cooler effect
when counting.
[Thanks Philippe]
And finally, we’re just suckers for a
good Nixie Clock
. The
scope clock
is also pretty interesting.

[StudioJooj] is trying to torture or test his colleagues in his office. A lot of folks leave a candy jar on their desks for all to enjoy but he’s making his friends work for their reward. Like cubicle-dwelling lab subjects, they must
successfully navigate his maze
to be rewarded with chocolate. The game piece is an amazingly orb-like peanut M&M candy. The maze is constructed from plywood and moves on two axis with the help of a couple of servos. The user interface includes a couple of NES console buttons to release the game piece and a PS2 joystick to control the maze. [StudioJooj] was nice enough to include a
music video
in his project clip.
We wonder the M&Ms will disappear faster or slower than they would from a candy jar.

[Rob] grew tired of his Makita power tool battery packs dying so
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.

That will drastically shorten the life of the reversed cell or even destroy it (depending on which battery chemistry it is).This is the same reason why instruction manuals for everything state to use only matched, new batteries when you replace them. You can get away with a lot in something like a remote control, but in a high-current application you have an opportunity to rupture a cell.",

My point here is if you care to grow a pair, you can get more real world useage out of your battery packs by replacing the one cell that goes bad until it becomes a PITA to keep doing that repeatedly.I disagree, it’s highly unlikely that any such battery pack will be subjected to such high current discharge as to become dangerous – far too much engineering has taken place to prevent that from happening in the first place. Homemade bundles with high current straps is another subject entirely and there your cautions become good advice.",

They may protect you from catastrophic failure some of the time, but even the safeties can fail. We have had a lithium battery explode in out test room, not catch fire, explode. If our lab tech was in the room he would have been severely injured. Sure you can hack cells together into refurbished packs, and they will kinda work, but it’s not worth the risk.On another note, when building a Li-ion pack for a project, be very wary of cheap chargers. I’ve seen a battery pack/charger combos that use a Ni-Cd charge routine to charge Li-ion batteries. Ni-Cd chargers can’t detect the end of charge of Li-ion and basically keeps charging until the protection circuit opens.",

Now I take care of them by trying not to burn them off.Another tip for people who extend this to laptop batteries: I took a very old laptop battery apart to figure out what cells it used and why it wouldn’t charge. I looked up all the parts on the charge circuit to work out what it did. What I was surprised to find is that the charging circuitry was powered by the batteries themselves. If the batteries depleted beyond a certain point, the charge circuit became inactive and there was no way (short of opening the pack) to get the module to charge. By trickle charging the cells directly (wall wart + 100R) up to about 6V I was able to get the laptop to resume charging duties. Of course the cells themselves were still shot so once the charger went away the pack died again.One further quirk which I never fully explored: The charging circuit had several parameters which could be programmed. The catch was that they were not retained in flash, just by virtue of — you guessed it — power from the batteries. So by the time the pack was dead, whatever parameters had been set were lost. This was an old NiMH pack so I’m not sure how critical they were. I can imagine a Li cell would be touchier.",

"content": "“interestingly some newer laptops have a “charge to 80%” feature that extends battery life somewhat.”The life span of Lithium Ion batteries is notably dependent on the average state of charge (SOC) that they are kept at.This is due to inherent chemical reactions which internally degrade the battery over time. These reactions are accelerated by high SOC and at high temperatures.Thus Li-ion batteries tend to have short life spans in Laptops due mainly to this effect (and of course the high temperatures).Since many Laptops are frequently used and stored with the battery at or near 100% charged, quick degradation of the battery is common.The real question here is why haven’t options existed in hardware/software to provide more intelligent battery management for ALL Laptops and other portable devices???Just having the option to temporarily disable charging of the battery when a Laptop is being used for long periods of time from AC power would really help to extend the life of the battery. (and would be less annoying than removing the battery)Settings to allow for only partial charging/discharging of Laptop batteries are also a decent idea which could have and should have been implemented a long time ago.My 2 watt-hours worth…",

"content": "Lithium ions don’t have a trickle charge mode at all. They can’t be overcharged. It’s typically 4.3 volts per cell and that’s it. If you go over the limit, they will vent and burst into flames.That said, the simplest battery management is a shunt over the cell to prevent its voltage from ever rising over about 4.1-4.2 volts. Like a zener diode, or something with a sharper response if you like. It wastes a little energy on charging, but you can charge the whole pack in series with a “dumb” charger that outputs approximately 4.2*number-of-cells and has a current limiter to prevent overheating the cells. The shunt does get hot, however, as 4.2 volts at 1 A for example equals 4.2 Watts lost in the shunt when the cell is topped up.And of the .5 kWh pack: if that seems huge, just think that you need 40 of them to drive an electric car some 60-80 miles, and you’d actually need about 80 of them if you want to keep doing that 4-5 years down the road, because the range starts degrading from day 1. You really need about four times, or 160 of such packs so the car would really hold its rated range to a more common 10 year life cycle.So yeah, pure electric cars aren’t quite ready yet as far as the batteries go. That’s the main reason why the EV1 had to be so tiny and slim, and why they built the Tesla Roadster out of a Lotus Elise instead of a regular road car: their energy budget is so much lower so they need less batteries.",

Be careful to put the good wires on the good side of the battery. The green light flashes.Then put the working battery on the charger normally.

I use one of those laptop charger that it was 19.5v to charge the pack to the 21.0v they have a regulator inside and they can be set to 21.0v . I recomend to replace all the cells on the battery pack not just the bad ones they are cheap laptop batterys on ebay most red cells are for little or slow descharge and the tools stop and go all the time just the flashlight and 1/4 inch impact works with it, green and blue cells are allmost all good",

A good explanation taken from the seller below:My new battery is dead already?As it stands testimony from the contact I have had states the battery does not last more than 50 – 60 charge cycles (if you are lucky!)Makita make some quality tools so don’t get me wrong but they have over-engineered this battery to the point it self-destructs.The battery is made up of two components a bank of Li-Ion cells and a Printed circuit board (PCB).The cells are self explanatory the purpose of the PCB in most Li-Ion batteries is to protect against overcharging, overheating and deep discharging all of which damage Li-Ion cells and can cause them to become hazardous.Makita have designed this battery with all these features plus more, there is a microchip which will monitor how many charge cycles the battery has had and constantly collect data from it. Futuristic stuff if a little over the top. The intelligent circuit will also detect a faulty battery and after 3 failed charging attempts it will disable the battery permanently. Now this is a safety first approach and if you look up the dangers of Li-ion batteries you will see why.Here is where it all goes wrong.The intelligent circuit inside the pack needs to be powered, and it draws its power from the very cells it is monitoring.The basic design flaw is that the circuit is wired to be powered by only one of the many cells in the pack. The PCB draws a constant although small current from that single cell. If the battery is not used for a few weeks then that cell will deep discharge causing a weak link in the bank of cells, the pack then fails in the charger.Now who is to know that if they try to charge the battery 3 times in this state they will permanently disable it? Human nature is think, why is it not charging let me try again.So if you use your tools every day you might have been lucky enough to have avoided this by charging them regularly.Most of the people will trow this batteries in recicling bin without knowing this batteries can work like new if you will use a intelligent Li-Io charger.I started to give a closer attention to Makita batteries and i can say from all faulty batteries which i opened,80% didn’t take a charge from original Makita charger because the voltage from one or more cell droped bellow limit….soon you will try one of this batteries on Makita charger it will reject the battery…if you try more then 3 times the PCB board will disable forever and this battery will never charge with any Makita charger.But it can charge with this inteligent Li-Io charger and the results will be more then satisfactory…why i’m saying this?…because this charger will monitor each cell any time(balance charger) and it will protect the cells against overcharging.In fact the original Makita charger IS NOT balance charger and this is one reason why since the voltage of one cell will drop bellow limit the Makita charger will mark this battery FAULTY.And now after this teory is time for practice:..i’m using almost every day this batteries and i can say i didn’t notice any diference between this and the ones charged with Makita charger.One of the picture will show the battery voltage after couple days after this battery was tested with running cordless drill.",

[Kurt] was using a bike trainer to get in shape for warmer and dryer biking months. Unfortunately it’s pretty hard to train if you don’t have reliable data concerning how hard you’re working. There’s commercial solutions for trainer computers but he’d read some rough reviews about them and
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
.

How To: Make A Printable CES Badge

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];
union()
{
scale( v = logo_scale )
{
translate( logo_offset + [0, 0, -1])
{
dxf_linear_extrude( file = "hack-a-day_logo-4-1.dxf",
layer = "wrenches_a",
height = 4,
center = false,
convexity = 10);
}

dxf_linear_extrude( file = "hack-a-day_logo-4-1.dxf",
layer = "face",
height = 50,
center = true,
convexity = 10);
}
}
translate( v = [ 0, 0, 0 ] )

}
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

[Jeremy] had some chips on hand that included EPROM. We’re not talking about EEPROM, we mean EPROM that need a UV light source to erase. Most people don’t want to drop a few hundred dollars on a dedicated EPROM eraser, there must be another way.
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?

I agree again with Mr. Richards that it’s a POINTLESS exposure, one that can be controlled, so do it.

Sure, we did, but scores of kids DIDN’T, which is why they’re a legal requirement now. You can go overboard, always a possibility, but for pete’s sake people, not everyone who’s concerned about a kid’s safety is a “helicopter parent”.

They’re both eraseable, but eeprom doesn’t require the UV eraser, thus the extra “E” meaning “electrically erasable read only memory”. So using EEPROM is fine for what you describe. The topic here is that EPROMs and Microcontrollers that are built using that as their code storage are a pain in the ass to erase because they require UV to set them back to their blank state.",

Unless the solder itself is coming off the legs of the chip, it’s not going to leave lead inside the UV cleaner.Moreover – if one is using SOCKETED EPROMS – there shouldn’t be any solder on the legs of the chip to start with.The casing of the chip itself is likely plastic or ceramic. No worries there either.In any case, one can CLEAN surfaces. Even if he needs to worry about contaminating his cleaner, a wipe down with a damp wash cloth should solve that problem.Yes, limiting needless exposure to toxins is a good thing.

These EEPROMs required no erase cycles, and programmed much faster than EPROMs.I even had a chip, a Dallas DS1225Y, which is a combination 8Kx8 SRAM with an integrated lithium battery for data retention, with a pinout compatible with 27C256s. This made programming blazingly fast and no erase cycles! The battery was rated for 10 years. I have one from 1993 and its data is still intact as of today.I substituted the EEPROM/NVRAM with an EPROM only when the firmware development was completed.",

How do you do that? Ionizing radiation. The photon energy of hard UV (aka UV-C) @ 254nm is high enough to ionize atoms and smash molecules. That’s where the ozone smell comes from when you run a UV-C lamp. The O2 molecules get smashed into Os … that’s also why UV-C is germicidal: it smashes holes into the DNA of those little critters. Which means it’s not too healthy for humans either.Now, there’s really no need to use clumsy old EPROMs. There are flash ROMs that are pin compatible with most EPROMS (29C256 is a good part). For other flash chips you can easily wire up an adapter board.",

Using a pacifier sterilizer to erase an eprom is precisely that.Now, assuming I had a baby, a sterilizer, and a chip that needed erasing, would I borrow junior’s gizmo to blank my chip? Probably not.There is no intrinsic danger in transporting gasoline in a properly-marked metal canteen, for example, but it’s not a good idea. Some things are best kept separate, simply as a matter of organization and good practice.Likewise, an atom or two of lead will not hurt anyone, but toxic metals and tiny, ingestible parts with sharp pins are inherently infant-un-friendly materials. As a matter of good practice, you keep babies and these materials apart.That said, no self-respecting Macguyver fails to stop at every garage sale and thrift shop in search of cool, cheap things to take apart/modify, and these are precisely the kinds of places you might find a used pacifier sterilizer for a buck or two. This is the one you can buy and keep in the workshop, “just in case.”I applaud the author’s ingenuity, and I will add this piece of hack trivia to my mental database.

Also, germicidal UVC fluorescents are made of quartz, not glass.Also, very important to anybody who wants to build his own eprom UV eraser:UVC germicidal lamps are extremely hazardous to the eyes. Just a few seconds of exposure to its “invisible” light can render you COMPLETELY BLIND!

Stroke To Unlock

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.

So a strip of this would be applied to the hem and it unlocks/locks the pocket in some way.I could see it as a replacement for a zip on a jacket, you swipe your hand down the middle of your jacket to open it….that would be coolplease contact me if you are willing to share the design i may be temped to try and make something like this..very very cool tho : )",

[Aggaz]
added 16 potentiometers to his Arduinome
.The
Arduinome
is a
monome
clone based around the Arduino as a microprocessor. We seen some
Arduinome builds
in the past but [Aggaz’s] work augments the physical interface.
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.

Weather Clock

[Sean_Carney] build this
clock that tells the weather
instead of the time. The two hands display the current conditions and the temperature. Forty below zero seems amazingly cold if you’re on the Fahrenheit scale but [Sean’s] from
Winnipeg
so he’s operating on the Celsius side of things.
Two servos move the hands to match the data scraped off of the Internet. An Arduino does the scraping with the help of an Ethernet shield. This reminds us of the
Harry Potter clock that tells a persons location
.

It would have been nice if both hands pivot on the same axis, as is the case with real clocks.It’s easy to buy hobby brass tubes. Consecutive sizes will slide into each other in a coaxial fashion. The larger, “hour hand” shaft could drive the temp pointer, and the smaller“minute hand” shaft could drive the cloud pointer. Heck, you add a third “second hand” pointer with barometric pressure, if you wanted.Granted, this complicates the drive inside the clock, but it’s not overwhelming, particularly since the shafts only rotate over a fraction of a revolution. You could solder a bellcrank to each shaft, and actuate it with a servo. Gears or even small rubber belts (neoprene O-rings?) would be an alternative.Just my 2 cents worth.

[Crabfu] pulled off some great chassis work on top of a remote control drivetrain. His most recent build
turns the tiny traveler into a lunar rover
complete with passenger and a communications array. For this he’s sourced the parts from a toy but boosted the realism with hand-painted details that leave us in awe. His previous project
sourced the body from a model truck kit
. Once again, it’s the paint work that makes us envious of his skills.
Both projects conceal a
Losi 1/24 scale micro rock crawler
that provides for some incredible locomotion. See video of both builds after the break.

This
single-digit Nixie clock
is a thing of beauty. You might hate Steampunk or you might love it, but you have to respect projects where the design gets equal (or more) consideration compared to the function. The electronics used in the project build upon an
existing single Nixie design
. Instead of
hiding the guts inside the clock
the PCB has been laid out to augment the design. We think [Blue Metal] hit it out of the park with this one!

Kodak Digital Frame Vulnerability
|
Mike Szczys
|
[
"Security Hacks"
] |
[
"digital",
"frame",
"kodak",
"vulnerability"
] |
Kodak managed to release a product with a big fat security vulnerability. [Casey] figured out that the Kodak W820 WiFi capable digital frame
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
.

In the media RSS file are a simple bunch of definitions of JPGs or whatever on your web server.Just put the dpf into Photo RSS mode, point it towards the XML file and you’re away.Thats what I’m doing. I have a little project on the cards to get the site dynamically generating my own pages as JPG files, info scraped from all over the web, then updating the XML to point the frame towards the generated pics. The dpf is great because it updates pretty quickly if you update the XML file – about 30 seconds to 2 mins which is fine when the frame is on a slideshow.I might write something up about it, its definitely the route to go down if you want to use it other than Flickr stuffs.",

LEGO Robot Lays Dominoes Not Eggs

[Mattias] brings the awesome once more with his
LEGO robot that sets up dominoes
. You’ll remember his work from the
wooden keyboard case
and the
mechanical binary adder
. This time around he’s still exercising those woodworking skills by making his own domino tiles, but it’s the robot that makes this interesting. In the must-see video after the break the device lays perfectly straight, perfectly spaced dominoes just begging to be upset by a spoiled toddler. The robot is nothing more than handful of LEGO parts powered by a tape deck motor. The parts may be meager, but there’s an abundance of ingenuity tied up in the design.

CES: Guts Guts Guts

We knew going into CES that we had to find some pictures of guts. It didn’t matter what it was, if there were guts showing, we snapped a picture. We were a little let down that the guts we found were basically consumer goods like cameras, TVs, and tons of amplifiers. The amplifier guts were so prolific, we actually just stopped taking pictures. We were hoping for some insides of tablets and such. There may not be anything new here for you, but if you are like us, you just can’t help but look. Join us after the break for a gallery.
Updated with captions. There isn’t much information, most of it was just on display with no one to talk to.

194 Transistor Clock Will Blow Your Mind

It’s nice to have tip put on our desks that we think everyone, yes everyone can enjoy. The
Transistor Clock
is just as its name implies, A clock that doesn’t rely on ICs. 194 Transistors, 400 resistors, 566 diodes, and 87 capacitors are all that makes this clock tick – no programing, and most importantly no Arduino. The clock is offered as a kit, but there is a complete
parts list
and
manual
(including debugging help) so anyone can build (and fix) their own. The Transistor Clock might even beat out the
VFD Clock
and the
Word Clock
on the ‘pure awesome’ scale, tell us your favorite in the comments.
[Thanks Hoopstar]

solar water heater setup that augments your home’s water heater
instead of replacing it. The system monitors a solar collector panel on the roof for temperature. If the temperature is warm enough, a photo voltaic cell powered pump circulates cold water through the system. The heated water returns to the top of the home’s water heater. Unlike the
warm-climate solar heater
we saw earlier, this one can withstand freezing because it uses silicone tubing in the collector.

Drain-back systems are of limited use when water will freeze in ten seconds(ever thrown a cup of coffee out and have it freeze before hitting the ground…I have). A separate heating loop with antifreeze is a much better choice. With a fairly simple circuit, you can also control how hot it gets in the summer. Just shut the flow off for a bit when it gets to hot. You need to ensure that the hot side can take the pressure or is vented.I have been kicking around building a system for my new house here. I have great southern exposure for a 24′ x 8′ set of panels. I have also thought about constructing a “heat battery” to hold the heat from the summer months for home heating use.",

Thus there are two independent systems, and capital expenditure has increased by something probably on the order of >50%. So to make sense the additional capital expenditure and maintenance cost must be balanced by a greater reduction of operating expenses over the lifetime of the system. Furthermore, the customer has to be willing to spend the extra up-front cost. If they don’t have cash on hand and don’t want to carry the debt, then it may make best sense for them to get the regular gas/electric heater only.Solar water heating makes best economic sense in warm and sunny areas, which is probably why they were popular in my hometown (inland southern california).",

There have been a couple companies that have shown off full-sized 3D displays, but Fujifilm had a couple of products that caught my eye. The first was a stereoscopic camera called the Finepix Real 3D W1 that not only functioned as a 3D Camera, but also featured a glasses-free 3D display on the back. 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.

After posting about our
visit
and
interview
with [Vemund], the Atmel rep at CES. We got the feeling you needed to know some more. The thing that has got us pretty excited is the ATmega128RFA1(
pdf
)
single-chip
microcontroller and Zigbee radio module. It can be found in the
ATmegaRFA1-EK1
development board. We look forward to seeing future projects and products involving this chip. How would you use this chip?

Encryption/signing of binaries should also possible. However, the ATmega128 (not RFA1) has a bootloader size of 4096 words (=8192 bytes) maximum. I would assume the ATmega128RFA1 has the same limits. I have my doubts that complex ZigBee protocol code fits in here (on the other hand, I really do not know how much code is necessary).@svofski:This is already possible, as Jkx mentioned, by using a cheap (433Mhz/868Mhz) RFM12 module.@Rupin:“In-System Programming” (over SPI) should always be possible. Beware though, that on the AVR Dragon (if you happen to have one of these) JTAG debugging functionality is limited to up-to-32K flash devices. Programming over ISP, however, is possible.",

If AVR had a standard bootloader pre-programmed, it would already be 10x easier to work with. For me it’s always the same procedure all over again: design/solder, make a human sacrifice, program the bootloader and fuses over the ugly wires, pray that it worked, start real work with bootloader over serial never having to fear of broken fuses again.Now if there’s a standard bootloader, the whole process is much easier PLUS you don’t have to route the oh-so-familiar programming taps. If there’s an over-the-air bootloader, it’s many times more easy because you don’t even have to route the serial pads (unless you use the serial for something else of course). Just snap it in, bzzzt, voila! But one can only dream…",

That cost includes the pcb getting done by BatchPCB, so volume runs would be less. While my hardware will cost less, I can’t provide the robust AT command set that the Xbee does. That is unless folks in the community come together and make something.@Jkx: I agree the current modules are pretty expensive (>$20 for zigbit & Xbee).

The AT86RF230 costs about $3.70 in singles from Digikey.Atmel also bundles radio chips with AVRs /without/ packaged discretely as well. These cost anywhere from $7 to about $20 depending.

It seems HaD is listening!@Xandl,The AVR Dragon ($49 USD) ISP/HVSP/JTAG/DWire programmer in-system debugger is no longer constrained to 32kB as of AVR Studio V4.18+SP1 released this month. If you will note, the Dragon firmware is automatically checked and updated by AVR Studio. This is long overdue and confirms ATMEL was intentionally crippling the Dragon to preserve market share for their other equally capable but hugely overpriced programmers. ATMEL is usually not like this, they understand making small money on overpriced tools and development software prevents the sale of parts, their primary product. If only Microchip (and others) would understand this.Oh yes, don’t believe the bunk that the AVR Dragon is “fragile”. The early V1 devices had some issues were fully addressed in the V2 boards. Virtually all boards in stock with common vendors are V2 boards.The Dragon provides not only simple ISP programming but JTAG and HVSP programming, one of which (depending on target chip) is required for programming certain protected fuses. And don’t forget you also have full JTAG and DWire debug support as well. Many ask why spend $49 on a Dragon when you can buy an ISP progammer for $19. I’ve just explained why.@Gerd,The ATMega1284P was supposed to ship this week from the likes of Mouser and Digi-Key. They seem to be late. But I’m sure the parts are released to manufacturing. Why are people so zoned-in on the ATMega1284P anyway? It is essentially the ATMega1280P but available in a PDIP40 package. Oh oh… I see, “Arduino environment saps up resources, need more memory, must have DIP parts for Arduino, must have ATMega1284P – yes master – Bzzzzzttt”. Forget the Arduino… If you must, just get creative and buy a PDIP breakout for the ATMega1280P for now. You also get soooo many more pins with the non PDIP part. It does seem though the ATMega1284P is a little cheaper.Don’t forget, you don’t only need the hardware, you need to IDE to support the hardware. If I’m not mistaken the ATMega1280 is supported in AVRStudio V4.18 with SP1 released this month. I don’t know about the ATMega1284, but since it is RTM it should be there too. Also, as I’ve stated elsewhere here, V4.18+SP1 opens up the AVR Dragon to beyond 32kB! Just in time for the ATMega1284.",

So I need to buy a zigbit (or something equivalent) and that’s pricey.I know developpement cost some money, but you can’t put a zigbee plug everywhere if a single module cost more than 20$ …For the licence, this is issue. I bought some kits and parts from Zigbit, but only MAC is free, for a full zigbee stack you have to pay for. In fact with the kit you have a evaluation CD, I lost it .. and Zigbit want to charge me for a new licence, that’s cost an arm …So for me this is not a good solution .. component are pricey, software is really hard to use, and cost you additionnal fee if you want to sell it.On the other the other side, there is 6lowpan and Contriki, but I’m wondering it this solution is a really interesting for an hobbist .. Do you plan to have more than 256 tags in your house, I don’t.That’s exactly why, I’m wondering if designing a small fully-opensource and roalty free protocol of top of an simple RF module won’t be better.I don’t want to flame this topic on the excellent hackaday, if some people are interested perhaps we can talk somewhere.

I have no idea what he will charge.I just checked out the Sparfun site for cheap RF modules. The cheapest they have is $20 based on a Nordic nRF2401A chip. At that rate, the Xbee is a better solution if you ask me.What you are getting at is exactly why I started my board work. I want a sub $20 solution for modules. Ideally I would have just bit the bullet and bought a bunch of Xbee modules. Problem with that is they require an external micro to do anything custom. I looked into taking their firmware and modding it slightly, but that is a moving target as they have modules based upon Ember as well as Atmel silicon. Plus modding their firmware could require commercial compilers (Ember & Freescale solutions).The bigger problem is to get the modules below $20, you have to buy in volume and sell them at thin margins. Digi/Sparfun modules are there to make money, not as development kits to sell silicon. One could argue Atmel et al. should sell their development kits for cheaper, but they all target commercial companies with huge volumes. Purchasing a development kit for $3,000 instead of $100 isn’t really a big deal to them. Atmel seems to be the best company in selling stuff for cheap (Dragon, Raven boards, etc). I have no experience with microchip, so my opinion is biased.Who knows, maybe I’ll get lucky and the demand for my modules will be enough that I can sell them via Sparkfun/SeeedStudio. The more demand there is, the cheaper the module cost will be. Volume, Volume, Volume. ;)",

It’ll also connect to the peripheral sensor boards I’m designing as well as a breadboard for checking out custom sensor circuits. Its mostly targeted at people that want a complete system to get into wireless sensor networking so its a bit more sophisticated than a a radio module. The real bitch is manufacturing the boards since, even with a pick n place, a lot of manual labor is involved.With this chip, it should be easy for people to make a simple module for wireless comms running on Chibi. The driver should aready support the 128RFA1 so the only thing to do is emulate an XBee pinout, add the RF front end components, and write some software to take data from the UART and send it to the spec’d address. I don’t think the full XBee AT commands are required. Most people only use a small subset of them.",

As were wandering around South Hall, we just so happened to stumble upon
Taser International
‘s booth. Being the adventurous guy that he is, [Caleb] decided to volunteer to get tased. Not being able to pass up such a great opportunity, we instantly broke out our cameras and recorded the video above. Enjoy, we know we sure did.

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. Another review video after the break.

We got to talk to an ATMEL representative showing off the RZ600 Zigbee system for AVR systems. The system was also displaying the QTouch slider and wheel devices, all combined to create a wireless controller for a tetris game running on the development board. It was great to talk to a representative with a lot of respect and interest in the university and hacking communities.

In a
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.

CES: 3d Laser Projection System
|
Caleb Kraft
|
[
"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.

We received a couple requests via email to get a look at Haier’s wireless TV. They used both wireless power and
WHDI
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
and integrate this into some consumer products.
[Nick]- There are a few companies here that are pushing wireless power products, but this definitely one of the cooler implementations that we’ve seen.

CES: Glove Input

The
peregrine
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.

We were hoping to get to test drive some of the 3d televisions that don’t need glasses. We had speculated about how they worked, and we were mostly right. It appears to be some type of
lens that works similar to those little printed holograms
. The strange thing is that we haven’t seen any of these TVs in the big name booths. The few that we have seen are in little booths at the edges. The big names are usually doing the polarized glasses or shutter glasses.
“it was nice not wearing glasses”… yeah, I know, I’m wearing glasses.

"content": "Perhaps you could describe the experience a bit more. That is, is the effect only available in a small area in front of the screen? Does the effect annoying reverse as you move left to right? I am speculating the answers to be “yes” and “yes”. And, of so, at that point I can understand why the “big outfits” are not that interested.BTW, I thought a lenticular screen was a reflective surface that preserves the polarization of the light. When someone says lenticular I think of two projectors with polarizing lenses and wearing polarizing glasses to view a 3D image. All I saw in the back ground was something that looked like a flat screen TV.If true, they are using a flat screen TV, then I suspect there is little magic at all going on here. By simply placing a vertical lined mask slightly in front of the screen, one can present independent images to each eye by interlacing two images each given alternating vertical strips of the screen. For one eye, the strips for a given image are hidden behind the mask but, for the other eye, they are completely visible. The problem? Viewers have to be in certain let to right positions for the effect to work. Further, the distance from the screen effects to viewers ability to experience any 3D effect.",

I still think the effect should reverse about every 3 inches.Any ways, wikipedia knows all! Spurred on to do a little research because of your post, I found this article which, if in fact this is what they are doing, explains a lot:http://en.wikipedia.org/wiki/Autostereoscopy((A couple of jumps later and I found this wikipedia note – which I think is deserving of it’s own hack-a-day post even if it is from a well know manufacturer:On page:http://en.wikipedia.org/wiki/Parallax_barrierIt says:“(a parallax display) is also being used for the navigation system in the 2009-model Range Rover, allowing the driver to view (for example) GPS directions, while a passenger watches a movie.”))…what a cool idea!",

Say goodbye to camera operators, as the viewer will be allowed to control the viewing angle entirely because a dome of all encompassing cameras.. also there wont be a need to place cameras to achieve “matrix” like bullet time effects…The only thing it wouldnt work for is LIVE events, since audience will be there.. Im guessing live events will be limited to several viewing angles, above court,end of court/field, behind rim etc…",

We’ve been given the honor of interviewing each team from the
Nokia N900
PUSH competition
one on one. However, rather than be selfish, we thought it would be fun and informative if the readers got to ask
the teams
some questions too.
Just post your question in a comment and we will be sure to ask.
Avoid the basics, like “what was your inspiration” – don’t worry, we’ve got those covered. But maybe you have that dieing question of “Haptic Guide: What kind of battery life do you expect with 9 or more motors constantly spinning, surly we wont be wearing Lead Acid around will we?”

While we were browsing around the show floor, we saw a pretty cool little robot called the
Mini Hexapodinno
. As the name suggests, it’s a hexapod robot that utilizes sonar and can be programmed using BASIC. Although its not as cool as some of the
other robots
that we’ve seen, we still have a special place in our hearts for hexapods.

CES: Keepon Keeps On

] |
We could not walk past
KeepOn
without checking it out. Not only did we get to check it out, we got to control it. [Caleb] picked up a wiimote and started tapping out a beat and KeepOn started dancing. It was as adorable in person as it is in the videos. We think it is horribly overpriced as is though, so we still
enjoy the home made one
.
We think the reason that KeepOn is so emotive is possibly because they have avoided the
uncanny valley
by a long distance. Video after the break.

If we Hack these Zig modules irresponsibly? We risk replicating the demise of 11 Meter Radio.. Zigbee today is like CB approx 1970 or so in my estimation. Flash forwards a few years and..In some urban areas, 11 Meters- the 27 Mhz “CB Radio” spectrum became literally saturated by overlap/splatter from crap grade transmitters running thru crappier amplifiers. All that was audible either AM or SSB modes was a growling buzz at times. Spread Spectrum modes do indeed have a greater tolerance for saturation of a freq range. But? there’s a mathematical reality that will get some harsh testing if Moore’s Law gets applied to Zigbee in our consumer daily life.We’re beginning to hack Software Defined Radio as a routine part of oh- Reflashing WiFi stuff. There’s a lesson to learn from CB Radio folks. *IF* some Hacking stunts generate crapstorms- the authorities WILL mandate “Robust Anti-modification Design Standards”So, let’s be damned careful about being good stewards of the RF spectrum as we Hack Zigbee etc.IF you think me paranoid or concerned about an impossible reality?

A rudimentary understanding of digital logic and simple integrated circuits is critical if you’re ever going to pull off some really gnarly hacks. [Daniel] put together an
explanation about the use of 4511 BCD 7-segment drivers
. These chips take binary data in and output decimal data to a 7-segment LED display. In short, they can read 0b1001 from input pins and light the numeral ‘9’ on the display. The best part is that you can build this example circuit in the
Atanua logic simulator
without ordering parts. We love zero-cost learning!

CES: PS3 Gun Controller

Yesterday we spotted a PS3 gun controller at the CTA Gaming Accessories booth. We have covered home made solutions like this before, like the
WeeP5 zapper
, and it is great to see alternative controllers spreading to other consoles. Now all we need is some
force feedback
, and we’ll really be able to feel in the game. As always,
Hi-Res
is available.
[Caleb]-I think the home made ones had better button layouts. See the thumb stick on the back of the pistol grip? They did that so it will work for right and left handed people instead of making it on one side.

Here’s a small update on the
AR Drone from Parrot
. We finally got this video uploaded. It isn’t anything fantastic, but you get a good view of the board on the bottom of the device. You can clearly see a tiny camera in the middle and what looks like sonar range finders toward the front of the drone.
As some commenters have stated, this looks like a more robust platform of the X-UFO. We haven’t seen the X-UFO, but the salesperson even mentioned it. Check out some flight video after the break. We’ve shot some flight video of our own that we’ll have up soon.

I’m impressed with the fact that they did manage to work the use of all of the fingers into the interface device.One thing I can’t really get out of the video is how it actually improves the user’s experience. I’m the kind of person who memorizes all of the hotkeys and uses them. For me, the experience with a computer is much more rapid than average. Keeping track of all of the windows mentally has never been a challenge. Would something like this improve my capacity to quickly operate a computer, or might it impair me because the pad for touch input takes up significant desk space (it has to – it must be big enough to be usable by people with large hands)?I agree with the idea that the mouse and even hotkeys have outlived their usefulness. As the complexity of operations a computer can perform increases and the number of menu options and hotkeys increase with it, organization appears to be the biggest problem. I just don’t feel they’re tackling the real problems that GUIs have. They’ve really only created a new way to move windows around and interact with them, but they still resort to lists of menu options in order to get the computer to do what we want it to.I think if this approach is going to succeed it’s going to have to take a radical redesign of GUI systems to better take advantage of all of the fingers working in tandem and it’s going to have to improve computing in some way (it can’t just be cool), either by making it faster to operate the computer so we spend less time doing it and more time producing, or by simplifying the experience so that people can become expert users more easily (granny doesn’t read instruction manuals or hit F1 – if she can’t figure it out by intuition the computer simply can’t do it).",

We hadn’t been here long when we stumbled upon the Drone tent. The
AR Drone is a
wifi
controlled quad
copter
that has been making waves recently. We actually got to play with one a little bit. Well, sort of. There was too much interference inside for us to fly it manually, but we did smack it around a little bit while they told us about it. It was amazingly steady and strong while it tracked a target around the tent. Check back later for more videos and details.

Today while walking around the booths, we saw a robot hand sitting out with a couple of exposed boards. This of course attracted our attention, and we thought we would share.
The hand is based on a
RoBoard
Vortex86DX board, which is an x86 control board. We even got the pinouts and datasheets, and we will post those later when we manage to get them uploaded.

We know a couple of you have been asking about the tech behind the show, and we managed to spot an FPGA (in this case, the Xilinx Virtex 5) serving as the core of a demo between two SuperSpeed USB Solid State drives. It was used as both a USB 3.0 hub, as well as being used to time the file transfers and get accurate speed reports. The
Hi Res Shot
is also available.

2-axis Motion Timelapse Photography

"telescope",
"time-lapse"

[Milapse] picked up a motorized telescope base a few years ago. He’s using it to
add motion to time-lapse photography
. The base provides two-axis rotation controlled with a handheld keypad. Custom firmware and a bit of software allow for computer control. [Milapse] is pretty well-known in the time-lapse photography circles of the Inter-web. He’s posted a
ten minute video
explaining his setup and programming work for the hardware.
His use of a quality camera produces
some nice video
.However cost at $200 for the base, if you just want to play around with the concept you might want to stick to
a webcam and LEGO setup
.
[Thanks Jack]

Got a special place in your heart for Atari computing? Now you can quench that need using new hardware. The Suska project has achieved
complete hardware emulation of the Atari ST using an FPGA
. The project’s progress tracker shows implementation of the major chips at 100%. They are running
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.
[Thanks Erik]

[Garagedeveloper] sent us his custom surveillance system,
part 1
,
part 2
, and
part 3
after needing a way to find out why some cables at work were becoming unplugged (spoiler, the cleaners were messing up the wiring). At the base of the system is a web cam glued to a stepper motor. However, it gets much more in depth with a web front-end that allows the user to stream the feed and control the position of the stepper. We’re not particularly fond of how many different parts the project takes, while it all could be accomplished under C# with ASP.NET and parallel port library instead of including Arduino and excess code, but to each their own and the project turned out a success anyway.

I could have suggested serial, USB, any number of connections – LPT is one of the easiest.

As for opinions, I never bashed his idea, I suggested an alternative for future revisions to spark discussion among our readers; It seems I have accomplished my task. Moving forward (third time is the charm) had you read, you would realize the project is originally in C#, see the @deoryp comment below for full synapse.@deoryp He uses C#, I’m not about to suggest he learn a whole new language simply to control a web cam. Regardless, having programmed in C, C++ and C# myself, while there are the trade-offs, I find C# much more user friendly.@sarsface You’re actually partially correct, when I was a fresh writer for HAD I tried to balance the side. If there were a lot of Arduino posts, I would lay off them. But either way there is no winning. If we write about Arduino, readers hate it. If we suggest an alternative, readers hate it.

Since the VNC client gives me remote access to the computer running the webcam, I can easily access the UI for panning and tilting the camera.This way, if my dog gets up on the furniture while I’m at the office, I just VNC in and play MP3s in iTunes of me yelling at the dog.One bonus to this setup is I can easily record the videos for uploding to youtube.

You can’t use it anywhere in the stream, so no USB-to-whatever connectors either.USB has delays, does bursts of data, and also compresses things into a serial stream, hence universal SERIAL bus. All of these things screw with timing and synching, so can’t be used for timing-critical apps. You would have to use something that works in PARALLEL, in real-time, and at decent triggering voltages.You know, like a PARALLEL port. Duh.The only part of it that is obsolete is using it for data transfer, something it wasn’t designed for in the first place.",

Version Control For Eagle

[Jeff] set up
version control for Eagle libraries and projects
. He mentions that Eagle has become the standard for open source hardware projects and he’s absolutely right.
We use it
for our projects, and we’ve grown to expect that the posts we feature have Eagle files available in most cases.
But Eagle falls short in its library management. There is some amazing work from SparkFun to support a usable parts library, but who hasn’t
added parts
themselves? [Jeff]
setup libraries using github
so that changes and additions to the libraries can benefit all and cut the amount of time spent making custom footprints for new components and packages.

"content": "I agree with the others stating non-GPL compliance. I personally haven’t been able to understand why the hobbyist would consider a tool that isn’t open and free? In the past I had used paid-for tools, but recently decided to look into being able to create a projects that utilize 100% free and open software to go from my idea to physical board (especially useful if I end up providing instructions to others for reproduction — they won’t then be reliant on some companies proprietary tool and said companies decision to charge 10 billion dollars for it, chop out functionality of the “free” versions, etc). I looked at eagle as there is a lot of people using it (granted it isn’t GPL as many have stated, but they do have a “limited” version). I couldn’t justify spending ANY amount of time trying to learn software that is intentionally limited in functionality, may not always be free and available, etc. It just isn’t logical.When looking at EDA suites, I couldn’t avoid considering eagle due to the sheer number of projects that use it. If so many people use it, it must be that great, right? Why are all of these others using proprietary software instead of open source standards such as gEDA (primarily gschem and pcb). Is there something inherently wrong with gEDA? Is it severely lacking? Even considering this possibility, I decided to try gEDA out…and my results were a simple circuit that worked flawlessly, very few difficulties in using the tools, and the wonderful surprise of plain text schematics and footprints that can easily be parsed/modified/etc by custom scripts.If you’re one of the eagle users, please give me some reasons as to why I would ever consider using it over the gEDA/pcb alternatives? The only thing I can think of is that some people already know it and continue to use it.If you’re someone like myself, trying to pick a EDA suite, take the time to check out gEDA. You won’t be let down. (BTW, I am in no way affiliated with the gEDA project/etc).",

What we need to remember though is that eaglesoft still give a stuff about us hobbyists… not many commercial suppliers offer us anything for free, even if it has limitations. I am pretty happy with the limitations anyway – the board size and max 2 layers of copper is about right with what one can do at home anyway as far as board fabrication.Eagle is also something that a lot of PCB fab houses provide rules for, and Eagle also produces useable output for gerbers, drills etc without any monkeying about necessary.Don’t forget the big issue of work environment – changing a pcb cad program will mean time spent designing is instead spent learning a new interface. I guess a good example for me is gimp vs photoshop. I cannot justify the $ for photoshop, so I use GIMP at home. At work I have access to photoshop. I am much more at home and speedier with photoshop as I am familiar with it. I get frustrated and waste time with GIMP trying to accomplish the same things, while it is still a very good program I lose productivity. I guess it is like a tennis player having a few games of squash before a tennis tournament – it will ruin their game till they get back in the groove again.A bonus for eagle is a pretty decent out of the box device library – something I got annoyed with with other cad apps which had very basic libraries.CheersJacob",

Eagle makes it simple: you install it, draw a schematic, press “PCB” and edit PCB, print PCB and ditto. Any changes you make in the schematic later reflect in PCB (as in traces rip and you have to reroute them, new components appear etc).With gEDA I can’t help but feel completely lost. I painstakingly edited some schematic and then what? FreePCB? Why? It isn’t a part of gEDA? WTF, I want one complete tool, not a set of broken half-tools. What’s the use of a schematic entry program if you can’t make a PCB out of it? What’s the use of PCB editor if you can’t edit PCB from a schematic editor? Yeah, I know, they’re kind of interoperable.

"content": "@svofskias for gEDA you might have to think in a Unix approach. One tool for one task.1. Use gschem for creating a schematic. Save it. STOP. That’s it not more not less.2. Use a text editor or gattrib to link symbols to parts (footprints). That’s much more flexible then using fixed libs. E.g. a resistor is a single symbol but it might have hundreds of different footprints.3. Use pcb. To make pcb read in all parts from the schematic there exist a script which converts all the stuff into the pcb format. Again one task one tool. pcb has no idea about gschem and vice versa. This may sounds complicated but allow much more flexibility. E.g. why not convert your schematic to a pspice netlist for simulation or into some VHDL, Verilog stuff, or any other format.Why should I not be able to import a pspice netlist into pcb to create a board ? Why not any other format ?You see …. it is more a unix resp. Linux approach… whereas eagle and kicad are more the windows-IDE approach. Coming from Linux world small tools which does what have to be done and the user in the middle of all this always keeps control is my reason for using EDA.However, I admit that it took me some weeks to understand and to come into the workflow of gEDA. Maybe that’s to much for some hobbiests.As I said it is similar to MS Word resp. OpenOffice vs. LaTeX. The latter beats the first two in all ways but requires some learning from the users side.",

I appreciate the flexibility, but I simply don’t want to use it for certain things, like circuits.Similarly one could argue that POVRay is better than Blender because POVRay allows you to edit model data in plain text, every finest detail. But alas, to create something complex, I need a modeler and I need to move my vertices and align textures interactively. I appreciate a possibility to alter data at low level, but normally I simply don’t want to care about such detail.So getting back to our conversation.. Eagle provides sophisticated scripting language and there are scripts that export netlists and PCB data and what not. You’re not locked in as much as some alarmists tend to imagine. You can export netlist AND footprints and import them in a third-party router and continue your work from there on, for example.I’d like to see more beginner info about both gEDA and KiCad in a practical context though.

"content": "Let me join the crowd of people saying that for open-source and open-hardware projects, developers should be (or should at least consider) using open-source EDA software more often, gEDA/gschem/PCB or Kicad being the two most common ones here.Granted, luckily various “open” project are slowly beginning to see the light by properly licensing the firmware source code (and possibly PC-side helper applications) under proper open-source licenses (GPL, BSD, public domain, or similar). This was not really the case in the not too distant past; everybody just put some stuff online, without any mention of a license, without proper license headers in the source code files etc. etc.You also have a wide variety of open development tools available on the PC side these days, including compilers and linkers (gcc for ARM, sdcc, avr-gcc, etc.), debuggers (gdb, or GUIs for it), JTAG and flashing tools (OpenOCD, urjtag, avrdude, …) and so on.If you’re really lucky, you nowadays even see openly licensed schematics and PCB layouts (CC-BY-SA, GPL, BSD, public domain or whatever) published by many projects, which is great!If you then also have a mailing list and some svn or git repository with the source code, where interested developers can easily contribute, you’re in Open-Source-and-Open-Hardware-heaven :-)HOWEVER, it is beyond my imagination why anyone would want to spoil the whole nice open project by needlessly introducing a closed-source component into the “toolchain” of the project, namely the EDA tool, be it in the form of Eagle or Orcad or Protel or whatever.I for one am reluctant (or plainly refuse) to contribute to “open” projects which don’t use open-source EDA tools. My spare time is too valuable to waste with closed-source software.I’m admittedly a newbie in the field of electronics, but all my (small) projects I have done so far have been designed and implemented using open-source EDA software, gEDA/PCB in my case, and I’ve been very happy with the tools.Here’s a small example project I am in the process of finishing up (some documentation, photos and source code still missing): usbflattiny, a small “capslocker”-inspired USB device based on an ATtiny45 and V-USB (previously AVR-USB).http://randomprojects.org/wiki/UsbflattinyI did the schematics in gschem, created two-layer PCBs in PCB, tracked all this development in git easily (including *.sch files and *.pcb files, as all of them are plain text files), sent the generated Gerber files to pcbcart.com and got my bunch of PCBs after a few days which work just fine. No questions asked by the PCB manufacturer, the default PCB Gerber output was happily accepted. All source code is of course GPL’d, schematics and PCBs are CC-BY-SA 3.0, all layout source files are in git, including new footprint I’ve drawn, etc. etc.So yes, you can do small open-hardware projects as well as bigger “professional” open-hardware projects by using a fully open-sourced toolchain, including the EDA parts, without any issues. You just have to try it. Yes, there are differences to the tools you might be used to, and yes, there may be some quirks in the usability (nothing that can’t be fixed though, remember this is an open-source project).But overall at least I personally am very happy with gEDA/PCB, and from what I’ve seen Kicad seems to be equally nice (though I haven’t used it for a real project, yet).I can only urge developers working on open-hardware / open-source projects to try out gEDA/PCB or Kicad for future projects. I think if you’re willing to spend some time to get used to the tools, you won’t regret it!Just my 2ct, Uwe.",

First the bad news, it’s too late for you to apply for this grant. The good news is that
you can vote for the projects
you think deserve money to do some good.
The Fun Theory is the group that produced the
musical subway stairs
and the
bottle bank arcade
. Now they’ve put out the call to arms on the Internet for submissions that make life more fun and our communities better places. All of the submissions for
the fun-theory-award
are in and available for your perusal. Some of the most popular submissions include a vending machine that uses recycled cans to play a slot-machine game, a hand sanitizer that makes funny sounds when used, and putting a giant crossword puzzle at bus stops to encourage ridership and make waiting more fun.

As I’m sure many of you already now, today is January 7th. While that might not have any real significance normally, today this means that our favorite hobby supplier, SparkFun, is giving away up to $100,000 of electronic goodness. We know we have our shopping carts filled to the brim, and we’re sure that most of you do too. With the start of Free Day being roughly 10 minutes away, we recommend that everyone man their shopping carts…. This should be interesting…

[Ryan] let us know about his
Max/MSP Controller
. Inside the device is an ADXL 335 accelerometer and 6 push buttons wired to an Arduino. The input data is sent to Max MSP, a sequencer controlling 5 audio tracks, correlating to 5 of the buttons. The 6th button controls delay. What we really liked was how the accelerometer modified the speed of the beat in the X-axis, and the delay intensity with the Y-axis. Whats next? We think
gesture recognition
might be something fun to try, but [Ryan] is unsure. We’ll keep you up to date.

Double Clutch Transmission Model

[Alan] did an extraordinary job building
a computer controlled model gearbox
. His project from several years back is based on a dual-clutch Direct Shift Gearbox that was developed for VW and Audi vehicles. His design uses a gear head motor to provide the locomotion to this transmission. Shifting is computer controlled through serial cable, with servo motors providing the physical motion to change gears. Seeing all these moving parts in the clip after the break might make you a bit dizzy.
This is some extreme model building. It reminds us of the guy who built
that aluminum aircraft model
that was all over the Internets in December.

Spatula Tzar
] Turned on her NES one day to find it
no longer working
. Off went the case and out came the oscilloscope. After probing around for a bit, she found that one of the RAM chips was very hot. 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

[Chris] is getting his feet wet with Computer Numerical Control starting with
an Etch-a-Sketch interface
. This is a great way to start out because the really tough parts of the project are already inside of the toy. He’s replaced the two white knobs with stepper motors and connected them through a mosfet network to a PIC 16f84a. The PIC then gets its commands from a computer via the parallel port.
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.

[youtube=http://www.youtube.com/watch?v=ChmDJ7RSZYE]
[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.

BT Phone Is Much More Than Retrofit

[Santiago] turned his
Ericfon into a Bluetooth phone
. This is completely different from the
handset retrofits
we looked at last month. This is because he didn’t simply crack open a BT headset and cram it into his phone. He developed his own hardware for full functionality.
This is an
open source
project with
available hardware details
that he intends to turn into a kit. [Santiago] has purposed a PIC microcontroller to connect with a
WT32 bluetooth module
. The PIC allows for a dial tone, dialing with the original rotary dial, and produces the original sound when the phone rings. What he now has is a way to have a home phone without a landline. 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.

Laser-cut Puzzle Box

One of our fondest memories from the 1980’s is watching Magnum P.I. on television. Higgins, Magnum’s employer, had a puzzle box that Magnum could never figure out how to open. Now you can
laser cut a puzzle box
for yourself and recreate some scenes from television’s glory days.
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
hellraiser
.

Powder Coating At Home

"oven",
"paint",
"powder coat"
] |
[j_tenkely] wanted to do
his own powder coat painting
at home so he built everything he needed, including a coating booth and baking oven. The oven is double walled and built around a frame of steel building studs. Electric oven elements are controlled by a digital control panel and thermostat.
A spray booth is fashioned from a large storage bin. The powder coat gun used in this setup is a commercial project. But don’t fret,
this is something you can build
rather than buy.

Over at EvilMadScientistLaboratories.com they’ve asked a question that many of us have never thought to ask. What exactly is Pong supposed to be? Instead of assuming it was ping pong like the rest of us, they decided to
build a literal physical interpretation
. They may have taken some liberty, using solenoids as the paddles, but the end effect is quite nice. Watching them play actually looks both challenging and fun. There’s a great writeup about the construction, so be sure to check out the project page.

Magnet would disengage as you activate the solenoid.",

[Oliver] received the Telly Terminator as a gift and
decided to take a closer look at it
. This key fob has two buttons; one shines an LED like a flashlight and the other turns off televisions. Sound familiar? Yeah, it made [Oliver] think of the
TV-B-Gone
as well.
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.

Pulse Oximeter

[youtube=http://www.youtube.com/watch?v=GdN5IRVJOXI]
[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
.

Not enough current and the LEDs aren’t bright enough to go through a finger. Too much current and the LEDs are over driven.Best of luck!",

[Dave] poked around inside of an IM-ME wireless toy and
compiled his findings
. He read about the device when
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!

Arduino I/O Speed Breakdown
|
Devlin Thyne

[
"Arduino Hacks"
] |
[
"arduino",
"AVR",
"I/O"

[
Jee Labs
] has worked out how long it takes for an
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
.

That’s what people new to hardware programming love about it and, inversely, that’s what people who know a lot about direct chip programming hate about it.Like JCS stated, moving all of the ports/registers into arrays so that they can be easily addressed by “pin” (array index) number will never be as fast as direct port manipulation. But like nilkoproductions and TJ said, it also enables you to use the same sketch on various arduino chips. If you use direct port manipulation and change chips, you need to go to the datasheet for the chip and change the port/bit numbers to match, which can be a pain for novices.Arduinos are a learning/prototyping/testing tool, not a production environment. If you need production quality, best to stick with direct chip programming and avr-gcc. More work but better results.",

Any library is going to have to check to see which register and bit a pin corresponds to, so you can call FastWrite(1, HIGH). Or will fill the memory with symbols, and leave you with a large set of macros that look more like Pin1(HIGH). The first method, is exactly what the Arduino library is doing. The second is going to get you only one pin write per time interval, where the registers will give you 6 to 8, depending on the register. Plus, a library like that would have to be re-mapped for each different Arduino out there, or do a lot of compile time manipulation.And if you are down to the point where you are actively worrying about the speed of the Arduino read/write operations, and want it faster than the register read/write calls, then you have probably stretched it as far as it will go.I suspect, however, there are some people using it that do not understand why an analogue read takes more time than a binary one, and are going to read this and assume it is a problem specifically with the Arduino.

With a capacitive (or R-2R ladder) ADC you need 1 comparator (that you can afford to improve in terms of performance, stability etc), 8 analog switches (easy to do in digital logic) and 16 capacitors/resistors…",

The ATMegaXX8 series are VERY capable CPUs if you learn how to program in straight AVR-GCC.An advantage of AVR-GCC is that it’s easy to port your code up/down to a larger/smaller AVR than the Arduino IDE. I prototyped a sigma-delta modulator on a Mega168 (Older Adafruit Boarduino model – new ones are 328s) and then ported it down to a Tiny85.Arduino hardware is a GREAT way to start with AVR programming, even if you skip the Arduino IDE.

One of the reasons that faster alternatives are resisted in the core libraries is that they’d tend to make timing “complicated.”It would be interesting (perhaps) to take a source statement like “if (digitalRead(1))” and walk it through various stages of (de-)optimization, starting with the single instruction/2cycle SBIS and adding features until you get the existing Arfduino function…(meanwhile, parties are invited to check how many reads per second of, say, a parallel printer port bit, they can get from their multi-GHz P4 systems.

As you
already know
, we’ll be attending CES this year. We’re still looking for ideas on what you, our loyal readers, want to see. We’ve gotten some good feedback, and came up with some ideas of our own. Keep sending in your ideas. Remember, it doesn’t even have to do with CES. Are there any hacker groups in Vegas that we could meet with? Any locations of interest? Let us know.
So far, we have the following requests:
Google Nexus
Notion Ink tablet w/Pixel-Qi display
Instinct Engineering – Suitcase XBOX 360, Fold out gaming couch
Car that can drive itself (most likely Toyota or Honda)
PSP 4000
Transparent OLED display from Samsung
Neuro/EEG Devices; Neurosky Booth

RepRap Acrylic Extrusion Using Hotbed

[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.

Generate Electricity With A Candle

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.

The difference on the Sterling side is that a motor spins the Sterling to control which way the heat is ‘ pumped ‘ ( to the house or from it in summer ). That said and getting back to the candle power, it’s an electric version of it. Instead of an LED ( to prove it is doing something ) the power can go in to any kind of buck converter to recharge a cell phone or other consumer device instead of lighting up a LED. Still, it is a nice little setup in the photo, the issue with a Joule Thief I have had is the coils and internal ‘ resistance ‘ to the base and the chance the power is backwards. Personal pref is germanium diode rectifiers and capacitor ( diode bridge stolen from a really cheap shake light WITH the capacitor )",

Fission or Fusion? o yea fission not good choice for powering your auto lol. but i think if i did enough research into things similar to the Peltier effect, i would eventually have discovered the Fusion Cell, solving the energy crisis. but if i dont get a lab or some funding i would expect the world to have to wait until about 2025 before the life-changing breakthrough discovery that makes lightsabers possible",

Record Player Display Sans POV
|
Mike Szczys

[
"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.

[Atlantageek] sent in a
missile launcher project
that he threw together. For Christmas he received a
Chumby One
and a
ThinkGeek USB Rocket Launcher
as gifts (lucky dog). Neither of these toys are “played with” in the traditional sense as much as they become
centerpieces of your next hack
. In that spirit, [Atlantageek] immediately wrote a widget to control the launcher via the Chumby. The side effect of driving his cat bonkers was an unexpected bonus.

[Rockwell] sent us
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

Just protect your outputs from the inductive kickback voltage (here the atmega internal protection circuitry does this job, but it’s really not meant to).While we’re at it, there are other security issues : using very thin wires to carry AC, splices covered with a piece of tape that is already starting to peel off … But then again it’s a “hack”. I’ve done this numerous times (with 240V) without problems. (The only time I was ever electrocuted was with a commercial product :-) )A funny thing is the USB cord, he made a knot but he left too little slack so if you pull on it it will unplug anyway ^^",

Although microcontrollers are cheap these days, you still might as well take some preventative steps to keep it alive; this kind of damage can ‘build up’ over time so failure is not always immediate.As for the ‘firestorm’, don’t sweat it – you were nice enough to post your work so ignore the harsh criticism.",
