[Amos] sent in the
Living Interface
. I call it a microscope reactive aquarium. A small light sensitive animal is inside a mini-aquarium on the scope plate. The wires are attached to lights at the edges to attract the animal. The position of the critter is reported via a digital aquarium. (looks like an empty aquarium combined with a projector. Aside from looking friggin cool, it has applications for measuring water toxicity by measuring the reaction time of the animal.
A while back, a friend of a friend supposedly used a USB microscopes to measure yeast activity in his beer brewing. If anyone runs across it,
let me know

Mr. Angeln is locked in the room after being deprived of food and drink for three days. The panels are under computer control, and behind each is a tasty cupcake and a glass of cold milk. The computer opens one panel at a time. It also tracks Mr. Angeln’s position via the camera. Should he get too close to an open panel, that panel will be closed and another opened.After a period of time, Mr. Angeln’s cries of protest will generate an individual, unique music piece, composed by an animal. In addition, the level of his despair/starvation/dehydration could be measured by the speed of his movements.It’s not torture – it’s an “interface”!",

Apparently I’m on a nokia 3310 LCD kick. [Coniferous] submitted
this
nice little pic project/nokia LCD implimentation. It uses a
DS18B20
temperature sensor, a PIC 12F629 and of course, nokia guts. (We’ve gotten enough of these that I’m starting to consider a Nokia LCD hacks category.) The parts count is really low – this could easily be encased

These measure temperature and relative humidity at 14 and 12 bit resolutions, with good accuracy/precision.It would be nice to see a translated page.

[Sasha] sent along this
video
. It’s a rather long (8 minutes) log of converting a checkpoint firewall into a home media player. The one in the video just needed a PCI video card, a and a USB hub to become a normal (yet still 1U) machine. I’m not sure what CPU was in it, but it was enough to run XP.

It could have used more of a “write-up”—and if it had been written up better it would have probably mentioned that other items can be hacked together into computers (not just checkpoint firewalls) such as office copiers and video game systems. I found the 10 minute video a refreshing change from the usual “takes me 30 minutes just to read and understand the schematic”……i liked the fact that i could repeat this hack if i were so inclined (one just never knows when one might find an old checkpoint at a flea market or rummage sale for $5)….unlike the laser cooked coffee, which was also cool.You people act like you expect “Mary Masterson” and “Wii Laptops” every single day!

[Eliot] and I hit [Major Malfunction]’s talk about RFID hacking. He’s put together a set of
python scripts
to read – and write RFID tags. He demo’d cloning a few tags – along with someone’s implanted RFID that’s used to lock and unlock a laptop. (It looked like the reader in the kit from
ThinkGeek
.) He’s kind enough to offer a selection of hardware on his site. (The usb RFID reader is pretty cheap.) His work has made plenty of headlines, including
slashdot
, but you can get the actual details, code and hardware on
his site
.

[brian] tipped me to this excellent
colormeter project
for calibrating your home theater/HD/etc It was designed specifically for the
HCFR Colormeter software project
. The project page is in english, but the probe writeup is in french.
The fish
well help you understand it while you resist the taunts avoid the flying cows. The device has at least one color sensor (a second is optional as well as an IR led or two for computer hardware controls) and connects to your computer via USB. The brain is a PIC 18F2550 (the fish calls it a PEAK) – no in circuit programming, you’ll need a programmer to build it.

This is because of how tv’s work. This sensor tells you the ratio of red/blue/green, so if you stick it in front of a TV the outputs will be almost exactly proportional to the r/g/b ratio that the TV is set for. So far so good, but in this day and age the colors used be a TV are no longer the same. There is a very noticable difference between a pure blue screen with my projector and with a LCD display, red and green are not as noticeable. So you would set the r/g/b ratios the same for all of your gear, but the actual color seen by our eyes will vary slightly depending on the color pallet used by the TV.But in general, a sensor like that would be a very fun toy! And you get the super bonus points for using USB…",

Make Your Own Fusion Reactor
|
Will O'Brien

[
"Misc Hacks"
] |
[] |
It’s staring to feel like a theme week. [Eric] reminded me of this 17 year old who
built his own fusion reactor
. Being me, I had to look around for more. I found the
open source fusor research consortium
. I found plans, research, and
this
fusor built by Richard Hull. It’s his fourth version – definitely worth checking out. Essentially, all the atmospheric air is removed via vacuum. Then you add a bit of deuterium gas, some high voltage and if you got it right, bask in the glow of your own personal fusion reaction. (Just watch out for X-ray leaks.)

Just watch out for radiation! Alpha radiation doesn’t matter here, but you need the equivalent of a sheet of plywood to stop Beta and Gamma radiation can be stopped only by lead sheeting or several inches of concrete. I recommend surrounding the chamber with lead flashing (get it from a hardware store, its used for roofing), except for a plexiglass window.Also, where do you get deuterium gas from? I can’t find it in my local chemical supply store, and my highschool has only small samples. eBay? UnitedNuclear (if there hasn’t been another Delta-Force raid on their server)?",

No need to get into the oil diffu$ion or turbomolecular pump$.I wouldn’t get too worked up about the steel chamber becoming significantly radioactive. Unfortunately, Brian’s decay curve xls data sheet from one of his experiments is offline, but I suspect the mass of all isotopes stays pretty low, even more so for long half-life isotopes.",

[lgbsneak] found a good
source
of pre-amps to fill his needs. Some older receivers, like his old Kenwood KA-305 have modular pre-amps. So it’s just a matter of ripping out, powering it up and tossing it into an enclosure. Now he’s got a handy 9v battery powered pre-amp for field work.

The
news
is awash about a 17 year old girl who won a $100,000
scholarship
for her spectrograph, but nobody actually linked to information about the thing. After some digging around, I located [Mary]’s
web site
. It’s a work in progress, but I found an
early version
of her spectrograph build. The picture shows her project with a spectrograph head made for a meade telescope. Hopefully she’ll get documentation of her spectrograph head up soon. This is one of the better uses I’ve seen for a 5mw green laser.
I forgot to mention her sweet
dobsonian telescope build
. Very nice work.

Sure, she is a very talented girl, and knows how to write a website, and has many skills that are had by very few teenagers, but what she has done is not any more technically challenging than many projects I have seen done (or even done myself).But, when you read CNN it is like what she did is orders of magnitude better than what the rest of hobbyists have done. And then people read that, and suddenly this hobbyist is famous, for a project not any more advanced than a lot of projects I have seen come out of teenagers (weather they be a work of literature, a painting/sculpture, a computer program, a electrical device, or something completely different…)I mean, the mechanical work was trivial. Several of my friends (and myself if I used my schools tools) could have easily done the machining. The alignment would take some time, but I have managed to get worse cases working (even try aligning a HeNe? 1/8 of a turn on a 100tpi screw will go from full to no power). The general concept of a ramen spectrograph’s is well published, and when compared to most optical devices is actually quite trivial. I have seen holography setups more complex than her design. So really, what puts the project above even a decent case mod is the effort that went into designing it. It takes a lot of reading (and you can’t find these books in your local library) and a considerable amount of head scratching to make a project like this from scratch.I speak from experience, as I am building a large dpss fd yag laser, which is currently in the collecting parts phase. I have some renders of the design up athttp://krazerlasers.com/lasers/yag/index.htmlI apologise if it is slow, hosting out my home cable line.I am not saying that her project is subpar (it is certainly one of the more advanced projects I have seen on HAD), in fact it is quite impressive for a teen, however the amount of hype it is given by the media (and many other people that don’t know what they are talking about) is way more than it deserves.",

[silic0re] sent in this uh,
totally
different take on micro-controller applications. The hardware is impressive. It’s built to carry up to 10 dsPICF3012 controllers (30 mips each), and has ethernet, SD, Serial and i2c thanks to an imsys
SNAP module
(similar to gumstix). This is, as far as I know, the first PIC controller cluster built. The software is still a work in progress- for now it’s just pretty, but he deserves points for originality. His site’s a bit slow, so try the
coral cache
.
(I woke up this morning thinking that I’d end up eating my words on my ‘first time’ statement.)

"content": "hi all,it’s really cool to be up on hackaday. so to your questions:1. I thought about the propeller too, but unfortunately it lacks a hardware multiplier. On floating point performance with the current open-source floating point library for the propeller I think I calculated a dsPIC30F3012 to be approximately 3 times faster than a given system using three propeller COGS (one to run your program, two to do the floating point computations). With 8 cogs per propeller, its still in your interest to use a dsPIC if floating point performance is your primary concern.(Propeller people may correct me on this — I’m just basing my numbers off those provided with the floating point code)2. You’re quite correct, this definitely isn’t the first time a number of microcontrollers have been connected together, but its certainly one of the few times that they’ve been connected together with the purpose of doing some purely mathematical task (rather than for the task of having more i/o, or controlling a large, complex machine). As far as I know only one other person has constructed a cluster of PICs, for a fourth year engineering project. This cluster was used to generate fractal images, but unforunately the website for it has long since gone. I think this may be the first dsPIC “cluster computer” (with the above purpose in mind).Also, yes, the LEDs are /very/ important!! :)5. I agree, and software that does more than blink lights is on its way! For a first cluster project I’m thinking of something that just verifies if a given number is prime or not. Seems like a perfect task where the communication between processors is far less frequent than the processing time required.I entirely encourage you to post here, but for those interested in the technical specifics and some further information on the thought that’s gone into the cluster (in addition to the information available on my site), there is a sparkfun forum posting here on the topic:http://forum.sparkfun.com/viewtopic.php?t=4930thanks for your comments and e-mails!",

"content": "@12: that does sound like it would be an interesting project, but building a ‘big’ CISC architecture out of multiple dsPICs means that most of the time the majority of the dsPICs would be inactive — it’d be the same bottleneck you find in pipelined CPUs. The performance gain you’d be able to get might be something close to the gain provided by hyperthreaded CPUs.The really interesting part about using multiple progressively smaller CPUs is that you tend to use more of the gates in your CPUs more often. If you think of a traditional von Neumann based machine, at any given time only a very small number of gates in the CPU are active (executing a single instruction), and a very small amount of memory is active (a few bytes out of mega- or gigabytes). If you have many processors, each with a very simple instruction set and a little bit of memory, you can increase the total number of active gates in your design (and, ideally, the overall performance of the machine).If this idea sounds neat to you, its exactly the reasoning behind a computer called “The Connection Machine”. Try googling it, and there’s a wiki article on it too.Neat that you’re at McMaster too. Computer science/Engineering student?",

got tired
of seeing the side of his USB card hanging out of his laptop. He cut it down and re-assembled it to keep all of it inside of his laptop. Nice clean work. I’ve taken PC cards apart before, and it’s a challenge to keep them looking this good after that.

I knew this was coming out, but [mike] was kind enough to remind me. [Ben Heckendorn]’s
latest
How-To is up on engadget. He provides a method of building your own A/V switch with as many inputs as you want, cheap. Each input uses a $.50 bus switch – literally, you could build one with 20 inputs if you really wanted to. (add some shielding if you do) If you’ve got too many game consoles, this might be your ticket. You can probably use the same trick to build a component video switch if HD’s your thing.

I don’t have the equipment to test them properly, but it seems that the audio ports have terrible bandwidth — they might even be filtered, it just occurs to me.Anyway, I thought this would be a cool project (+20 points for incorporating a cheap IR/laser/whatever sensor for remote switching?

Printer Hacking Roundup
|
Will O'Brien
|
[
"cnc hacks",
"Uncategorized"
] |
[] |
Today’s roundup is in honor of all those inkjets, laser printers and plotters that have been cracked open and modded to perform unspeakable tasks. This is a bit of an experiment, so let me know what you think.
First, there’s the classic
DIY CD printer
. Aside from dremeling the back of the printer, making the cd cartridge from a decent material is probably the most difficult task. I used to print on my DVDs, but now I just rip ’em to my media server.
Not really a hack, but someone discovered that they can get ever nicer photo transfers if they use an
inkjet instead of a laser printer
to create the transparencies.
Not to be forgotten, using
the fuser from a laser printer
to transfer laser printed artwork onto PC boards.
If you missed it, [Volkan] and [Stefan] gutted an Epson C84 to make a
direct to PCB etch resist printer
. The feed the board in and get a printed design, ready for the etch tank. (once it’s dry, of course) Someone else is working on the
same hack
with a C87.
If you’re evil, there’s the classic
paper shredding printer
.
You could use an old network printer interface to
control something else
.
If people you work with actually read the lcd, you might have some fun
exploiting the displays
on those HP workgroup printers.
You could pick up an old pen plotter and convert it to
cut vinyl
for your nefarious custom stickers.
Speaking of plotters, there’s the ‘
scribbler bot
‘ – AKA diy pen plotter.
Of course, maybe you just want to
fix
your old printer after you completely dissassemble it. (Via
zedomax
)
Maybe you can make your own
waterfall printer
. (If you pull this one off, let us
know
)

I saw a simular professional device that used adhesive paper that was used to make a skull from a scan to determine what someone dead would’ve looked like. Cut a square and then cut the image inside it, but perforated, so you could just stack the squares easily, then cut off the excess off with an exacto knife (also seen on the above professional rapid prototyper).",

This particular hack is actually used in a kit design, but it’s still pretty sweet. This is a digital read out unit that’s a kit sold by
shumatech
. I’ve even mentioned it in passing before. The design takes in the pulses from inexpensive chinese made
digital scales/calipers
, and allows one stop calibration and ouput of three axis’s of measurement. Using the interface and a usb enabled pic, and you could make your own usb digital calipers… (Hmm, I might have to make some.)

It is also useful for calibrating CNCs, and as an additional feedback, thought the idea there is that the stepper and ballscrew can move a precise amount when told so you don’t have to go x then go back to get to y. You can see if this move was a cut why such an operation won’t be good, since that extra would be cut you didn’t want.",

[Tony] submitted his
site
showing his recent projects. Besides his
balancing scooter
, and
light creations
, I thought his take on the
balancing skateboard
was interesting. The drive components came from a pair of $10 cordless drills, and the motor controller consists of a pair of relays and mosfets.(There’s a pic controller, gyro and accelerometer behind them) It’s not elegant, but these sorts of hacks are great for inspiring those on a budget.
Don’t forget, the new revised US daylight savings time is coming.

I’ll be busy with my soldering iron tonight, but I thought it was time for an extra.
[Joe] notes that if you’d like to put up some graffiti you probably won’t get arrested for, you might light
projection bombing
.
[Emil] noted that [mark] successfully upgraded
his ipod mini
to run an eight GB CF card. (He’d previously put a 4GB flash card in.
[XanTium] notes that several patches have
been released
for the Linux 2.6.20 kernel specifically to support XBox 360 hardware. A Linux loader is soon expected to be released to exploit the Hypervisor vulnerability.
[CtrlAltDefeat] pointed out an interesting DIY
camera card to hard drive
memory dump device.
[Bobby] sent in a teaser of his DIY
bluetooth Sony MDR 300
headphones.

World Weather Umbrella

Will O'Brien

[
"Misc Hacks"
] |
[] |
[Peter] brings us the
oddest hack
of the week. It’s a little esoteric, but interesting. This modified umbrella is used in conjunction with a giant world map outline. A camera takes note of the umbrella position and correlates the location. The user walks around and ‘experiences’ the weather in that location of the world. If you’d prefer to have everyone think you’re nuts, you could just interface it
with your ipod
.

Automatic Color Detection

Will O'Brien

"Misc Hacks"

[] |
[KLOZ] submitted his
final project
from college. Rather than an expensive CCD camera, he used a set of colored
resistors
LEDs and a light dependent resistor (I’m assuming he means a photo resistor) to determine the color of a product (m&ms). He used the carriage from an old HP inkjet, a custom cnc cut wheel to separate and deliver the m&ms and a Parallax propeller micro controller board to tie it all together. Now he can hog all the green ones for himself.
Update: Yes, I’m an idiot. I did mean colored LEDs. People who caught me will get an email – I’ve got something for ya.

Zach Norman
] built this electric bike on a Harley frame. I couldn’t dig up much in the way of details, but the
flickr photo set
looks good.
[Micheal Raines] built a
great looking
electric chopper.
In the lightweight category, this hybrid (pedal/electric) bike uses li-poly batteries and a simple motor-tire drive to keep going. via [
hacknmod
]
Early this morning [tnkgrl] sent in her
HSDPA mod
for the OQO Model 2. Engadget beat me to it, but it’s a great mod for anyone who visits outside of those handy EVDO areas but want the speed for their UMPC. Living in the middle of nowhere means that I’m stuck with RxTT.
[andrew] built a handy
parallel port A/D converter
– so far he’s got it logging temps. The parts count is pretty low, depending on an ADC, a 555 and some OP amps.

I was under the impression that canon firmware hacking had fallen by the wayside a bit. [random guy] pointed out that Canon firmware hacking is still alive and well, but it’s the smaller consumer models that are getting the attention. Several cameras, like the
A610
happen to share the same digic II image processor as my Rebel XT. By uploaded some modified firmware, you can shoot RAW format pics, and get quite a few other features as well. There’s even a HDK (Hack Developer Kit) for rolling your own firmware. Most of the work appears to have been written up in Russian, but there’s an
english wiki
and
guide page
to get you going.

Also, for that extra 50-75$ I can buy a lot of batteries or rechargables with charger and extra space on SD card. And check how much you have to spend on another battery for your SD.

For your needs check into a program called PSRemote fromhttp://www.breezesys.com/and their add-on utility called WebCam Zone Trigger fromhttp://www.zonetrigger.com/which has a special edition to work explicitly with Canon cameras and PSRemote. This allows you to set hot-zones in the Canon camera’s FOV to detect motion and snap off pictures when it detects motion. The link for the special edition (for Canon cameras and PSRemote) is available through PSRemote’s pages if I recall. It’ll do exactly what you want (but at a cost, unfortunately).",

This isn’t a brand new hack, but it’s a great solution for most digital cameras that like to go to sleep on you.
[T. Black] put together a nice simple pic circuit to control a cheap aiptek digital camera. It uses a 12C508, a cap and a resistor. The PIC not only activates the shutter, but can wake up the camera from sleep mode. You don’t even have to provide a dedicated control channel – it can piggy-back on the throttle control signal. The hardest part of the project is tapping the signals on the SMD pc board inside the camera. There have been quite a few R/C camera controllers built, but this is certainly one of the most elegant. You can grab the code and schematic from the bottom of the project page.

GPS Enabled Radar Database

The
page
pretty much lacks every possible detail, but [Mattias] put together his own RADAR camera notification. It uses a published database of camera’s and a GPS receiver to notify the driver that they’re approaching one of the many permanent speed detection cameras in Sweden. Despite the lack of details, I can guess about the design. It shouldn’t be that difficult to construct something similar with a PIC or AVR with a decent amount of memory. Just compare the current location with the list, and notify the driver when it determines that it’s within a specified distance. Unfortunately all the RADAR detectors where I live are strapped to police cars.

It is no more illegal than getting on the phone and telling your buddies where the speed trap is that you just saw, or after passing said speed trap, flashing your lights at oncoming motorists as a warning to slow down.As far as the police are concerned (publicly, anyway), all of these things accomplish the very same objective: getting drivers to slow down.And I’m sorry, but it takes about 5 minutes and full attention to change the speed warning in my car. I can’t set the speed warning for every street onto which I turn.A *useful* device that would alleviate the concerns that radar detectors are used to speed would be a proximity-type device that “read” a transponder on each street and updated the speed alarm within the car with the appropriate speed. Thus, whatever street you’re on, the speed alarm would be automatically, and correctly, calibrated.It would still be the driver’s choice, however, to turn it on…",

[A. Smyth] passed this along – it’s another take on the non-mechanical dance pad. The first prototype used IR detection, but apparently the hardware was flaky. The new version uses cheap laser pointer style diodes with photo detectors. Personally, I want to see one that breaks the laser into a line and collimates the resulting beam, and senses beam interference by measuring the intensity. (And it would look incredible with a fogger) The electronics are pretty simple – the photocells are interfaced with the guts of a USB game pad and breaking the beam creates a button push.

Buttons in the arcade are sunk by a few mm and this little difference is vital to determining your position without looking away from the screen.I see a lot of “unique” ways to build a DDR pad, a someone who plays DDR daily I’ve researched many of them before and simply abandoned the idea once it was determined to be unsuitable.I’m all for “hacks” as as much as some hacks are useless I’ve always felt the ultimate goal to be expanded functionality of an original design.

"content": "I play a fair amount of DDR on my MAME cabinet — and I play well enough that my cheapo soft pads have become the limiting factor to improvement. I have been wanting to build some good pads for a long time so I read this article with interest.I see tremendous problems with this design, though. Some I believe can be remedied but others are going to be much more difficult. Thee first and most major problem is that the design lacks every single feature that a good DDR player relies on to position themselves — the edges between buttons can be felt with your feet on any soft or hard pad I’ve ever played on and it’s critical for there to be some kind of tactile indication there. I believe you could fix this problem by building a thin substructure underneath the pad to give the player something they can feel with their feet rather than just relying on some kind of invisible (or tape) grid to tell them where their feet are.The second big problem is that the pads design gives it a very large raised edge. I can say with some certainty that if I played on this pad I would trip on the edge and fall. I have big feet and go ‘outside the lines’ a whole lot. Other people might not have this problem.The third problem is that you have to break the beam to register — so you have to put your foot dead center on the beams axis to get the step to trigger. On a real pad you can register the step by pressing on the very edge of a pad. This is an absolutely critical feature for advanced players.The last major problem I see is that technically the pad is open for cheating since you can trigger two of the standard arrows by stepping into a corner. Although some people (particularly advanced ITG players) are fairly adept at triggering two pads with one foot anyway, taking it down to this level of ease is a little much. I think this problem is solvable too though — but to keep a design without an interior frame, you would need more beams to make it work.The last (minor) gripe is that you cant play anything other than 4-button songs. Again more lasers or a different beam design could enable this but it’s still going to be easier to use mechanical switches.I think that if you really want to build a solid state optical pad the best way would be to use take a cue from the multitouch builders out there and use (fairly thick) polycarbonate steps that are illuminated from the side with IR. When an object is in contact with this from the top it should reflect a lot more IR down underneath than the blank panel would. Using an IR sensitive phototransistor or photoresistor and some nice little PIC code that compares the input of these to a baseline calibration reading of the empty pad you should be able to build a quite sensitive and responsive solid state pad.",

While
clocky
runs away from you,
this
alarm clock can probably strike back. It’s got a pair of basic stamps along with relay’s to control external devices. [Jason] built it from parts he already had, and has visions of it being used for stage fx control later on. For now, I’ll bet that none of the guests will want to attempt turning it off for fear of reprisal by the clock.

Fresh off the
tip line
, [Ben] sent in his
one wheeled balancing scooter
. It’s a nice simple design – I just might have to build one myself. The steel frame surrounds a pair of 12V 12Ah SLA batteries, a 400w 24v DC motor, one of the ever handy
OSMC
motor controllers, rate gyro, accelerometer and a PIC 16F876A. I love the entire concept! (For some reason, I’m thinking it needs a brake light on the rear…
Check out the video after the cut. He walks through the hardware at the end.
By the way, Eliot and I’ll be at
Shmoocon
in a couple of weeks. We won’t have boards from the Design Challenge yet, but we should have something to give away to people who find us there.

The deformation of the tyre and the formation of a triangular contact patch is what enables you to turn, a high centre is not required.The axle was turned on a lathe. It’s a very simple design – I’ll put a sketch on the site tonight.I’m not sure I agree with smaller wheels or one on either side. Having two wheels would require some kind of user input to determine the rate of turn, with one wheel you control the whole thing with your feet and movement of mass.Can you imagine riding a snowboard with a potentiometer to control your rate of turn?",

I’ve found unless you have friends in, or with immediate access to a machine shop; having parts done from ether a CAD, or simple dimensional markup is a major headache, and in most cases expensive as hell(Probably why we don’t see decent formed metal parts on most entry level robotics projects.)Metal stock is also expensive because so few sources sell it that they’re able to over charge because of the whole supply and demand model.Also regarding patents. I know first hand that in the field of robotics, electrical engineering, and most other fields anything innovative you create is most likely gonna be covered by some greedy guts patent even if his design is barely similar to yours. Big corporations try to cover as many concepts as possible when they apply for patents, and there applications are usually approved quickly. The same applies to millionaires who decide one day they want to take advantage of consumerism through cheap components wrapped in injected molded plastic that entertain.",

[F00 f00] over at acidmods put together
this PS2 -> PSP controller
. Using some similar techniques to [
Ben Heck
], he tapped all the control lines on his PSP and broke them out to what appear to be mini-usb connectors. Looking like a matrix subject, his PSP attaches to a dash board suction cup mount. Via

DIY ‘midi’ Footpedal
|

"DiyMidi",

"FootPedal",
"midi controller",

[forrest] passed along this diy
foot-pedal ‘midi’ controller
. It’s a good re-use of hardware, but not a true midi controller. The pcb was gutted from an old keyboard, and the pedals were scored from a mad 60 mile tour of the local radio shacks clearance bin. Since the pedals are simple momentary on switches, it was a matter of wiring them to the controller and using a laptop to generate signals via usb midi interface. Replace the keyboard pcb with a
drum controller
and you’d have an interesting stand alone solution.
Just so I could enjoy some extra crow, I managed to leave
one other
entry out of my published list of Design Challenge entries. [Jason] sent in this MEGA32 programmer/dev board. He kept it single sided, but you’ll need a parallel port to use it.

some screen shots
of his MAME360 app running on a developer system. Why care? A hop over to [

‘s blog
points out a
recent vulnerability
in the Xbox 360 Hypervisor. Thanks to [XanTium] for the original tip.

Ground Up Diy Laptop

[Chris] sent in his
diy laptop
. While it reminds me of the kid laptops at the toy store, it’s a nice effort. It’s got a PICAXE 18X microcontroller, 20×4 blue serial lcd, a laptop keyboard and runs his custom built language: chris++. Power comes from four AA batteries, and duct tape secures the electronics inside the wood case.

[chris] put them all together and then took the time to write up what he had done and took pictures and then explained how it was done in detail.[chris], when you are ready to start working with plastics and build your own CNC mill let me know….i have a few good stepper motors and motor control chips to spare ill throw your way that your 4 dollar radio shack soldering iron will be perfect for ()()ldk337@@@aol…com()(). i look forward to future hacks of yours! and dont let these jerks get to you—you did good my friend.you did good. i like it!",

These are not just for the creator of that DIY laptop but also for companies and right about anyone who wants to give it a go.I find that what was done in that project comes close to what I would want to see in a laptop that one could do from the ground up let me tell you what I see that I like;1) It’s low cost.2) It’s low-power consumption and the batteries are generic (No ridiculously expensive batteries. When are laptop companies going to learn that?)3) It’s got the basics input-output. Crude, but no different than say some of the earlier electronic word processors that Radio Shack used to have.Now, here are my suggestions to IMPROVE it.1) Get something that’s a little more powerful than the current micro-controller. There are many embedded systems out-there that carry more bang for your buckJust three examples…http://www.jkmicro.com/products/v25.htmlhttp://www.rabbitsemiconductor.com/products/SingleBoards/And last but not least…http://gumstix.org/These will give you the extra “oomph” that you would seek and would carry support for a larger LCD and even include ethernet and audio.2) Stick to off-the-shelf components. You will save a bundle in prototyping and hours of head-aches in trying to figure out how to make it work.3) Use generic chipsets. That way it can be used with almost any of the major Operating Systems.4) Stick to a modular format. That way not only one can customize their lappy as they like, they also can also fix it themselves just by replacing a component.Other than that? Use your imagination.TPW",

I don’t think either the gumstix or SNAP have a straight-forward LCD or keyboard interface, and you could surely add an SD/MMC card without too much trouble.That being said, I think I like this project far more than just using one of those off-the-shelf solutions for ‘functionality’. There’s something really to be said about building your own system at the board level, and using microcontrollers to do it at that! If anything, maybe you should just set aside all the suggestions for ‘making it more functional’ and start to “downgrade”. Make your own 3-bit CPU out of 74xx’s on a big project board, and add a ton of led’s on the bus. That would be too cool!",

This is a bit reminiscent of the missing DC entry, so consider it a bonus hack. [Eric] sent in his latest project, an
AVR game console
. It uses a pair of ATMega168v micro-controllers, a nokia 3110 LCD, and an eeprom to store a selection of games. The interface above the console is the serial loader/charger. No word on the game source, but judging from
his site
, maybe he’s writing them all on his own.

I thought I’d mentioned every entry of the contest, but I managed to let
one
slip through the cracks. One of our favorite hardware hackers [sprite_tm] submitted this
AVR
ARM dev board/game console. The LCD is from a Nokia 5110. The brain is a LPC2103 ARM controller, and is designed to run a
chip8 emulator

DIY Fiber Backlit Keyboard

"laptops hacks"

In honor of the 17 inch aircraft carrier of a laptop I ordered, I started looking for a backlit keyboard mod that might come close to the one on my powerbook. I found
this
mod that used fiber optic cable, a single 10,000mcd white LED, some epoxy and simple current regulation to light it up. The original write up is
here
, and a great looking
blue version
as well. I’d like to see it this with a control circuit like
this one

This
design has been around for a few years, but it looks like a good introduction to ultrasonic sensors. The design is surprisingly simple with a low parts count. Of course, if you prefer PIC controllers, you might like
this
version.

I haven’t seen an augmented reality setup in a while. The
Tinmith backpack
consists of a VR helmet, with helmet mounted GPS tracking, firewire video camera, orientation tracking, glove based user interface and a belt back that contains the mobile computer and batteries. These systems have very interesting applications. From navigation to correcting information in real time to work around partial blindness.

Printer Networked Light Control

[Andy] sent in his ‘
Network Something
‘ hack. For his proof of concept, he used a parallel port printer network adapter to create a set of network controllable LEDs. The virtual printer was implemented with a set of shift registers and a set of nand gates. (and a power regulator). Old print servers can be had pretty cheap – my HP $8 on ebay. Definitely an interesting way to get inexpensive network control of your projects.
Note: We’ll be making some server changes today and tomorrow, so comments will be offline for a bit. They’ll be back.

The last I remember, the network object is passed an ip address and a port. Since all we are doing is sending a byte at a time to the print server on port 9100, the programming is rather simple. I did look up information about ports on some other print servers. They state that most are defaulted at 9100 and can be changed if the device allows. And in your case with the jetdirect box, printer port one is 9100, port two is 9101 and so on… I am using a port sniffer to see what other ports are available on my netgear server plug so I try to access the other pins of the printer port.",

[Mark] sent in his
wireless classic nintendo controller project
. He built a wireless NES and SNES controller to use with his Wii via the Gamecube port. He used off the shelf TX/RX hardware and used some PIC controllers to glue everything together. iPod batteries keep em powered and keep the weight down. He provides all the schematics and a walk through on
constructing
the SNES controller. The circuits are pretty simple, so it’s definitely repeatable. This is almost enough to get me to buy a Wii.

electronics, but when I was younger, RF controls always seemed to be the black magic of diy electronics.

[David] sent in his
laser beam analyzer
project. It’s a complete analysis system built from off the shelf hardware. Even if you’re not into lasers, the project combines several technologies that are useful for the hardware hacker. A laser beam is focused to shine onto a spinning reflector. Beam signal is attenuated by adjusting the distance with a stepper actuated sled. The beam is then measured using various sensors.
I thought we were due for a
laser hacks category
, so I created it and added some of the older laser hacks to it.

Many times laser aberrations only become apparent at focus, so imaging the beam before focus only gives an estimate of the focal spot.The choice of setup is a little strange. His experiment operates under the assumption that with a fast oscilloscope, your temporal resolution (times a constant velocity) is better (cheaper) than the comparable spatial resolution of a translation stage. However, he runs into timing and signal amplitude problems with leads to trouble with triggering and noise. Overall itâs an interesting way to measure a high power focal spot with resorting to equipment in the $10k range.",

[squishy] sent in his iBook refit
project
. Normally a laptop ressurection wouldn’t grab my attention, but the wireless card caught my eye. Because his ebay deal didn’t come with an airport card, he refitted it with a Senao 200mW wireless card. The card just fit – and with some dremel work on the antenna connector, it was plug and play under linux.

This
one
reminds me of a MAME arcade controller. This control panel is just the gravy on top of a very nice
CNC conversion
for a Sieg X2 mini mill. (Like
mine

Bluetooth Enabled… London Bridge
|
Will O'Brien

[
"Misc Hacks"
] |
[] |
[Mike] sent in a
different
sort of hack – as part of the switched on London
festival
, these guys added bluetooth sensors to London Bridge. When a bluetooth enabled device is detected on the bridge, a blue ‘pixel’ will show up on the upper tower bridge. Once the device is detected at the other side of the bridge, the ‘pixel’ will move across the bridge at the same speed as the device did. You’ve got a few more days to check it out if you’re in the area.
Update: Just to be clear – the sensors are on the new London bridge, and the pixel/light appears along the top of Tower bridge. Sorry for the confustion, I haven’t been in London since 1995 or so. I mistakenly assumed that the lights were on the upper tower of the bridge.

[since studies have shown again and again that we are losing social capital due to the ease of electronic communication.]just some food for thought i guess?",

However, I have seen no moving lights on London Bridge yet, although some months ago red lights were added to edges, probably unrelated to this project. Blue strip lights where recently added to the railings around the scoop, but again it seems unrelated to this.The artwork of the Belfast is not reflected in reality, there are no large beams coming from the guns, although there are new lights there which illuminate the underside of the guns and flicker oddly, looking much like malfunctioning fluorescent tubes.The other pages (not including those marked with ‘concept’) are equally not reality – unless they only have it on at weekends, which would kind of defeat their statement of 8-16th for the festival dates. City Hall and Hays Wharf do not look like their pages, and I’ve seen no hanging red lights on the south walkway yet. (I’ve not seen the Design Museum, but I may have a look tonight).The only exception is the Tower of London page 2 – it does actually look like the top photo.

"content": "Just to clear up a few things (I did the custom electronics and software for this project).This is the first year of this event and it was done on a near-zero budget to get something happenning in the hope of making it a more regular event with some proper funding next time. Many of the projects on the SOL website did not happen for a whole number of reasons but unfortunately they didn’t update the site, which gave a slightly misleading impression. Some things got changed/cancelled at a very late stage – we were all set to install on London bridge and then found out the access cradle was not useable. The decision to change to Tower Bridge happenned about a week before we had to start the install,and even after that it was off & then on again once DURING the install…. In fact the Tower Bridge setup works better than a London Bridge one would have as people on London bridge can see the effect themselves.Since the start we have had a few power supply problems, but the only night we were completely dead was Sunday & we have had one of the 2 sections missing on 2 other nights.We would certainly have liked to have had more sensors – ideally 2 at each end to get a speed and direction by the time people reach the ‘first’ end of the bridge so the speed accross the bridge can be matched better. Time, budget and availability of the RF modems simply did not allow this. All the sensor hardware & software, and the controller hardware & software was designed and built from scratch in about 2 weeks.One major issue in using Bluetooth in this way is that you are stuck with an update rate of the order of 10 seconds due to the randomising of the response time from the detected devices. Range is also somewhat variable, so on a relatively short span like this it is not practical to get especially accurate speed data. However at less busy times it is easy to get see a very obvious response to individual bluetooth devices as you move along the bridge.One approach I am plannning to investigate is the use of multiple bluetooth modules doing staggered, overlapping scans, as well as using RSSI data.One good thing that has come out of this is a load of data we can sit down and look at to see what might be achievable with more time, and a budget.I will be adding some stuff to my site, hopefully including some video, as the dynamics are what really make it work.Regarding the ‘hackiness’, there are a couple of things not yet on my site that fall into that catagory – firstly we programmed in a number of ‘magic’ MACs for the phones of some of the people involved in the project, so they get their own special display. Also I have a ‘test’ trasmitter that lets me make it do all sorts of wizzy stuff from anywhere that is within view – this is particularly good for freaking out tourists when yougo up next to them, pull out what looks like a big TV remote and start making things happen on the bridge….We will be doing a presentation at dorkbotlondon on this in the near future – possibly March",

Coilosapien: Rail Gun On Yer Robot

"Laser Hacks",

[] |
It’s been a while since we’ve seen anything new on the robosapien front, but I’d say that a
laser sighted rail gun
for our favorite robots is worthy. From the video, it appears to have decent accuracy and a fair sized clip. It’s creator, [Marcus] says that he’ll have a tutorial up soon. Thanks to [
Robert
] for the tip. (Update: The tip says it’s a mini rail gun, so I’m not sure if it’s a rail gun or a coil gun.)

Here’s a little bit of a blast from the past, but I’d bet that many of us have encountered
this
problem. Keyboard contacts can wear out, be damaged by drink spills or that vat of acid you left by the TV. Automotive defroster repair paint should work – if have some handy. [eeun] documented a keyboard contact repair method using household aluminum foil and superglue.

I’ll keep this short and sweet. Fabienne, Eliot and I unanimously chose [Nuxie1]’s
entry
as the winner. His board is a nicely done USB PIC prototyping board. [Nuxie1] gets some
sweet prizes
and some bragging rights. Congratulations [Nuxie1]!
It seems that our
tips line
has been screwed up for the last week or so. If you’ve got something good, don’t be afraid to re-submit it.

"content": "Firstly, a big thanks to Hackaday.Mine and a lot of other USB PIC designs are based on the Microchip USB Bootloader, which requires two buttons for bootloading. The other one linked uses the 18F4550 40pin chip, which in SMD is much harder to solder, and for DIP would not really fit in the size requirements. It also does not provide schematics for the pictured board.Mine leaves all of PORTB free for a byte sized I/O, whereas others need one or more PORTB pins for USB Bootloading. I don’t see it being “oddly the same”, they use different chips, laid out differently, have different I/O connections, different power connections, different software.I also worked hard on the design to have NO vias, and single sided so it is easy for anyone to make at home. Others I have seen all have lots of jumpers/vias, or are double sided.I have used it as a base for a number of projects. The Microchip C compiler makes it very easy to prototype things, the full PORTB I/O makes it easy to connect ‘data line hungry’ projects, and USB makes it easy to communicate with the PC.I realise there are similar designs out there, but I have spent a lot of time designing mine from the ground up, with the features I have outlined above and on my website which I hope differentiates it from other designs. So I get quite offended by comments that it is “oddly the same” as other ones.",

"content": "well done, nuxie1, well done. What I suspect most people here do not understand is that it is the fine details that take up all the time in a project. As you said, minimizing vias or jumpers in a layout, clean design… these things all take thought and time. Whipping together a hack that fits on a card is the easy part. Making it clean is a much larger task.I just did an 8-layer 5×7-index-card-sized design and I can assure everyone here… the schematic is the easy part. The layout was heavily dependent on parts placement, and manufacturability relies extensively on choosing parts with compatible footprints, attention to RoHS standards (at least for BGAs, I learned that you can’t mix RoHS-compliant BGAs and non-compliant ones on the same side without extra costs), board density issues for proper reflow and probably a dozen other things. It’s the attention to detail, as what nuxie1 has shown here, that makes a project great.Yes, voting would be a nice feature, but I would prefer to have the final decision left to a panel of judges who takes the popular vote into account but can also take into account issues that the population is likely not even looking at. “Cool” factor only gets you so far, and it shouldn’t get you top prize.",

They’re $25. The nice thing is that it’s pre-built (a kit version is coming very soon that will be less expensive) and the software that comes with it is super easy to use (i.e. you don’t need to write any code to get it running). The code that I’ve written for it makes it appear as a virtual COM port on your computer, and you can send it many different commands to do lots of different things – like it can turn all 19 I/O pins into 19 separate RC servo outputs, etc.Main UBW website ishttp://greta.dhs.org/UBW*Brian (EmbeddeMan)",

That’s not very big, so the options of things you can actually do with it are limited. I think a lot of commenters forgot the original rules of the contest and were just thinking Hack a Day was having a contest for THE ULTIMATE HACK.When you think about the rules for this contest and look at this winning entry it makes sense. This guy worked really hard to design a very logically laid-out PC board. He did a great job at what he set out to do, and followed the guidelines of the contest.Of course, to many of the readers of Hack a Day (and most average Joes on the street), if you handed them a PIC programmer, they’d say, “What is it?” And then when you told them what it is, they’d still ask, “What do I do with it?” On the other hand, if you cram an Xbox 360 into a laptop case, you’ve got people’s attention–and I think that’s the sort of thing a lot of people were expecting to see as a winner. Because, hey, let’s face it, for most of us, when we come here every day, we’re looking for some everyday object being used in some very unorthodox way!",

The design is very aesthetically pleasing. However, the designer mentions that they have eliminated via’s. Well what about the through hole components? For any effort of ‘via removal’ to merit any real recognition, all SM parts could have been used… SM parts are usually cheaper than TH anyway. 0805’s or at least 1206’s for the caps would have been surprisingly cheaper and still maintain effortless assembly.As for the layout, Microchip has a wonderful pinnout already, and from my experience, I don’t see any great effort needed to do what’s already fairly easy with this given pinnout. What about diode protection for interfacing to the outside world? Surely you won’t rely on the low current internal ones? The I/O’s on the chip won’t last long here.Also, I can’t remember off hand, but isn’t RA4 an open drain output? The schematic has this as driving an LED high (I could be wrong here). Also, the whole Port A in general will need pull ups, or hope an external device has pull-ups in order to input any data. Being used as analog input? Again, use protection scheme.Port B has weak pull ups that can be turned on (is the booter turning them on?) But they are week. Let’s hope nothing on the input loads them down.Now for the kicker, lets hope to high heaven’s that someone doesn’t actually connect a real RS-232 cable to the UART connection because there is no level translation.Again, sorry.",

If you spent as much time researching as you did finding flaws you will see that on 18F PIC’s (or at least the ones I’ve used), RA4 is NOT an Open Drain. I have tested my design in both SMD and DIP version, and all pins function correctly as both input and outputs.I am working on a full SMD version, however as in the rules through hole components were preferred so it is easier to make. Hence why I have SMD and DIP PIC versions. Also, by vias I meant jumpers for a single sided board as well. Eliminating them means it is very easy to make at home through toner transfer or other methods. It is also hard to find small quantities (one or two) of SMD parts.The PIC has diode protection on all pins inbuilt, and as it is meant for general use most people will not need further protection. Same for the analog port, pull ups are not needed if it will be used as a digital I/O in most cases.As for your ‘kicker’, it is not meant to be connected to an RS232 port obviously. I have used it for PIC to PIC, or other low voltage level communication. There are many small circuits to convert it to true RS232 levels using the MAX232 or other similar chips. I did not put on a MAX232 as I feel the USB port is sufficient, it adds extra cost, and then you could not connect it to 5V serial devices.If you or anyone else would like to discredit or find flaws in my entry, please post it on my website. I feel I followed the HaD contest rules completely, and their suggestion of a PIC programmer/dev board if you read closely.",

If you went with all SM parts, then you wouldn’t have to touch this board with a drill!!! That would be easier, imho, than the benefits of th parts.…at first glance at digikey, 0.1uF 1206 goes for 1 cent a piece and the disc is 2.4 cents. It also appears as thought there are more readily available of the SM than the discs.>The PIC has diode protection on all pins inbuilt, >and as it is meant for general use most people will >not need further protection. Same for the analog >port, pull ups are not needed if it will be used as >a digital I/O in most cases.O.k. It was just my experience, that when interfacing with other boards, I’ve popped that internal diode many times, and those 18f’s get expensive.>As for your ‘kicker’, it is not meant to be >connected to an RS232 port obviously.

I find that I talk with RS232 levels more often than TTL UART levels.Now, if it’s any concearn of yours, I will tell you that if you are feeling angry with me…, you did get your revenge on me, becuase as I was taking the time to write this, I actually missed an ebay item I had be watching. It went for $50, and they normally go for $200. Dang it. Darn it. Dang it.",

Meet the
DIY Dvorak keyboard
. I’m feeling nostalgic this week, and I was surprised that we’ve never mentioned this simple, but useful hack. Heresy history lesson: the qwerty keyboard was created to slow down typing – because old typewriters jammed too easily. The
Dvorak keyboard
is more efficient because the letters that are most often used are positioned closer to the fingers natural position. [Anders] swapped the keys on his
Swedish thinkpad
, and even customized the map a bit further to his own taste.

"content": "This oft-told history isn’t quite true. The Qwerty layout predates touch typing. It may have been one of the ways the jamming problem was redressed, but not because it slowed down typists — rather, it may have been used to change the placement of levers in the machine that would frequently be needed in succession.One thing that isn’t debatable is that the Dvorak layout is better. It’s somewhat unclear exactly what advantages can be measured in practice, in part because of retraining issues (and good comparative studies on new typists are hard to find). In my case it dramatically reduced hand strain and significantly reduced typos.-Carl",

Yes, it takes a while, but how hard is it? At least they should make it easier to switch on an OS.I agree with #3. The levers would clinch if typed to fast on old machines. So, yes it slows down a bit since your fingers have to move more often, time-space relation here. But that is slightly slower. It is clever anyway.

You can search Flickr for some dvorak macs :).I say that there is no sense in keeping the old shortcut locations, because they were designed with the qwerty in mind. ctrl+v has no attachment to paste, except that it was next to ctrl+c.Windows does have problems switching layouts after an install: the login will remain qwerty.

I popped my keys off and rearranged them to suit. It makes it really amusing when people want to borrow my computer. I credit Dvorak with getting rid of the wrist pain I used to have typing (I’m a programmer, so my ability to type is part of my stock in trade). On the downside, it did take me months to get good at it (I used no tutor program), and going back to a Dvorak layout isn’t particularly easy. I’m not a really natural typist, though, so YMMV.",

"content": "“the qwerty keyboard was created to slow down typing – because old typewriters jammed too easily.”This is bullshit. Mechanical typewriters do indeed jam easily, and they jam most easily when two keys in close proximity are pressed in quick succession. Therefore, one of the foremost considerations that determined the QWERTY layout was to place keys that are often used in sequence as far apart as possible. Other considerations that have an impact on typing speed were given lower priorities. Therefore, the QWERTY layout is not exactly conductive to quick typing on machines that don’t have the jamming problem.So, this layout was created in a way that slows modern typists down. BUT it was not specifically made with the goal to slow down typists — big difference. It was made to speed typing up, because on a mechanical typewriter, even though you’re not super-fast with QWERTY, you would be even slower if you got jams all the time, or if you had to be extra-extra careful to avoid jams.",

Somehow, [acidx] knew that I coveted a libretto for years. He sent in his
writeup
on modding his Libretto 50ct to be a bit more useful. The mods are pretty basic, he overclocked it to 133Mhz and added a ps/2 port. The tweaks keep the well aged libretto a usable platform.
Pssst. wanna see your hack on Hack-A-Day? Use the

[] |
Here’s the final batch of entries we received and considered for the Design Challenge.
[Chris] sent in a
stereo amplifier
(watch out for pop-ups) designed for iPods (or similar) using LM386 amps and a minimal parts count.
[Fabian] submitted this excellent
tube amp
. It’s based on the ECC83/12AX7 tube, and runs off a mere 12-14VAC.
[Edgar] sent in this combination
PIC/AVR programmer
.
Finally, we’ve got a simple
PIC/EEPROM programmer
by [Ian]. (view the unzipped version
here
)

Adding 802.11n Into Your Macbook

According to Apple, all of their current machines are compatible with their new 802.11n wireless hardware. The guys at MacBidouille wanted to know if they could get it
functioning
in their early rev macbook core duo. They ganged a new card from a MacPro and got busy.Things came out ridiculously easily, with a simple hardware swap. Considering that the pci connector is the same, I wonder if any portable with an airport extreme card could be upgraded (with an additional antenna)

DC Entries: Almost Done

"contests"
] |
[] |
We finally came to a decision about the winner of the Design Challenge! (But I’m not telling you until Friday.) Before the winner is announced, there are some more entries that deserve attention.
First, there’s [Henk]’s
g-force meter
. It’s based on an ATiny26 micro-controller, 30 LEDs to display the force and the ADXL103 accelerometer.
There’s an
adaptation
of the no parts pic programmer, by [Patrick].
[Evan] sent in his
PIC prototyping board
using the monster PIC18F4550.
I’ll have one more batch of entries later this week, and the winner will be announced on Friday. Yes really. I’m going to give it a few days just to make sure that all of our DNS issues have cleared up.

This
robotic beer launching fridge
is one of those ultimate projects that you are guaranteed to see posted all over the internet today. Robots, beer, the possibility of maiming innocent bystanders… what’s not to love? I’d be lying if I said my mechanical engineering friends and I weren’t contemplating this at many points during college. Kudos to John W. Cornwell of Duke for actually pulling it off. The mini-fridge has three servos: one to elevate beer from the 10 can magazine, one to rotate the turntable, and one for cocking. Spring power is used to catapult the beer across the room. The brains of the system is an ATMega8535 and 3 intelligent H-bridges. It’s controlled by an adapted key-less entry system. It looks like they’ve wisely placed it pointing away from the tv, but I don’t know if referring to your apartment as the “man-pit” is nearly as smart. Check out some of John’s
other projects
: the
Mentos booby-trap
and the
touch activated paintball gun
.

We’re not really hung, but it is taking a while for us to decide just who get the title. While we decide, here’s a couple more entries remind you what it’s all about.
[Razvan] sent in
this
excellent entry. (I’m hosting it on my personal server since he didn’t have one)
The writeup could be a bit clearer, but the design is pretty sweet. It features a mega avr brain and a microchip ethernet controller with a software based USB interface. It’s a pretty intriguing design – lots of possibilities for ethernet controllable projects.
[Tom D] sent in
this
rolling codes garage door opener. This will step through all the garage door opener codes for garage doors made before 2003.

[Terry] sent in
the first
of his projects that he’s posted on his site. Having grown up in the midwestern US, I can’t even express how badly I wanted to build one of these puppies when I was a kid. His remote control lawnmower is essentially the bastard child of a three way between a R/C car, a wheelchair and the lawnmower. The radio is interfaced with the control box from a wheelchair, otherwise it’s a good welding project.
Nice work. I’ve one suggestion – a safety circuit that disables the mower if radio control is lost. There are a few devices designed just for R/C projects that’ll do the trick. (Update: ok, there’s a failsafe in the design but I wouldn’t call it optional!)

Most of you won’t remember that there once were lawnmowers without motors. that’s what I mean by “push mower blade”. It was gear driven by the force of you pushing it.the remote control powered one was electric and a ton of fun. But very hard to get accurate enough to do perfectly straight lines. It would mow alot of grass and real fast. But guiding the things is just like trying to guide a remote control car in the exact line you need to cover row after row of grass cutting.People would stop in the front of the house in amazement.

[Christopher] sent in his modded TI-83 calculator. (Hit the read link, a bug is broke the one I tried to embed) Besides the uh, racing stripes, he added a PS/2 port (though I see
drivers
for this mod are up on ticalc.org) and an integrated (cpu controlled) RGB backlight. The backlight is controlled with a programmable AND array that’s slaved off a pair of the CPU I/O lines. Just to top everything off, I poked around and found that you can
overclock
these puppies, as well as
expand
their memory. I’m hopeful that wetsanding and varnishing the thing 10 times smoothed out the paintbrush lines, but an inexpensive airbrush would yield much smoother results.

My favorite method is to use 5min JB Weld as a filler/adhesive. Just block up the bigger gaps with electrical tape, and spear some JB all over the joint–and i mean really goop it on. Once it’s totally hardened (24hrs), you can sand it down into a nice smooth shape that slows seamlessly into the calc’s body. When you paint it all, it can look quite professional!",

This one
wins my vote for unintended use of hardware. [nathan] sent in his bent modem. His breakout box takes midi signals in and uses them to generate various modem sounds from an old Packard Bell external modem. Now, how about some schematics? Hit the
link
for videos of it in use.

[Dyer13] sent in his Zune antenna
mod
. It’s a simple one, but we haven’t seen too many Zune mods yet. It’s really just a matter of adding more surface area to the transmitter. I’d suggest adding a wire that’s actually tuned to an appropriate wavelength. If you want something with a bit more power, check out this Belkin Tunecase
power upgrade
.

I’ve lost count of the number of emails from people looking for these things, so here it is. The hardest part of [Mike’s]
little hack
is the soldering. The pins on those iPod connectors are just evil to solder. You’ll need the patience of a saint.
I’ve worked with these same connectors and I came up with an easier, if bulkier method of soldering those things in my
iPod super dock How-To
.

Yes. the dock is made for docking iPods, but suppose your ipod died and won’t come back to life. Or it got stolen, and somebody cheaped out and bought you a shuffle, or maybe you just want to plug the dock into your computer to over-ride the built in speakers? The cable allows you to use the dock for things besides an iPod. You could plug in an old-school MD player, a digital voice recorder, I mean, anything with the mini plug. I’m surprised Bose doesn’t just follow the lead of Klipsch and make the dock accessible to other media players. Even say, little “vidiots” with their PSP’s could Crank it up at home…",

However, if you don’t need an extension that long, and want a cleaner look without cord clutter then I’d recommend a product called the Dock Extender by Sendstation (they’re online). This little gadget extends the iPod so you can move it from dock to dock, and it’s made to work right through all cases that have a dock cut out. Plus, it looks natural, like you just extended the iPod an inch or so. They go for about 30 bucks.But, what’s even better is something they make called the Pocket Dock. It is simply a dream! It has an 1/8″ miniplug out (plus RCA w/ included cables) S-video out(ditto RCA cables), and a USB-B connecter (synch/charge). And all for about 30 bucks! And considering it comes with the cables, it’s insane. No power is necessary, as it runs right off the iPod. But don’t worry about battery drainage, because it has a USB connector (just get a cigarette lighter to USB adapter) and it doesn’t draw much power anyway because it has no lights. It just works, and without fail! It easily hooks up to any home or car stereo. The home stereo just needs to have non phono composite (RCA) inputs and the car stereo needs either a stereo miniplug (1/8″) input or a cassette deck (and a cassette to miniplug adapter).And just like that extender gadget, it’s tiny and just looks like you extended your iPod a teeny bit. Plus, it bevels out at it’s connector, so it fits through cases without needing that Dock Extender gizmo.",

Thanks to [Ryan Bucshon] for letting me know that Hack-A-Day is up on Attack of the Show tonight. Looks like they’re talking about the Wii Laptop by Ben. Hit it right now.
Update: Excellent, I got mentioned, Hack-A-Day got direct coverage, then they hit Ben’s site, and mentioned Ben’s How-To series on Engadget.

brought this
sweet project
to my attention. The table is reactive thanks to the combination of a projector and a video camera below the surface. The position and unique pattern of each block on the table is used to manipulate the operations of the synth. The
software
is open source – so you can build your own. (And it’ll run on linux, mac and windows) Check out the
videos
for a good demonstration. I’m thinking that one of these could be built on a budget using lumenlab/overhead LCD technology.

The
final part
of Ben Heckendorn’s
Wii
Laptop
How-To is up. Somehow, Ben managed to get access to a laser cutter and a CNC machine (in friggin Iowa) and used em to create the new case for the Wii Laptop. Add dash of soldering, a few simple circuits and some clever case construction. Voila.

I probably shouldn’t find this as worthy as I do. It’s the optical recognition equivalent of wiring up a LED to a switch,, but it just appeals to me. [Ashish], one of our favorite optical recognition hackers of late, sent along
this
product of his boredom. If only he’d give us some source and a wiring diagram…

[Alberto] sent
this
along. [Jose Pino] put up a nice how-to on modifying a cheap quartz clock to be used as a 1Hz (1 second) pulse generator. I can think of a number of past projects where this would have been really friggin’ handy.

Tesla Powered Sauron’s Eye
|
Will O'Brien
|
[
"Misc Hacks"
] |
[] |
[Peter] sent in his
latest
Tesla coil experiment. He calls it the “Eye of Sauron” effect. It was created by adding a
rotating breakout
to an already powerful Tesla coil. It isn’t quite the same as the old evil eye of Tolkien’s dreams, the picture is a 22 second exposure of two rotations of the 7 foot aluminum tube.

Our own Hack-A-Day emeritus took some time out from his showgirl pursuits to pass
this
along. The ECG was built to pad a resume, but it doesn’t make it less useful. Be warned, too much power could stop your heart. If you build one, triple check everything before wiring yourself up. Basically, an electrical differential is generated by the contraction of muscles in the heart. This slight signal is amplified by an op-amp and sampled with an A/D converter.

Caveat emptor.There was a Scientific American article on how to do this that is the cleanest amateur design I’ve seen:http://sciam.com/print_version.cfm?articleID=000C74E4-5172-1C74-9B81809EC588EF21Again, be very wary of hooking something like this up to your computer, scope, or any line-powered instrumentation. For this you must have better isolation than Carlson’s design: look at the EEG design posted from the University of Sterling above.",

There are reasons that medical devices need FDA approval before they can be used, and have to be inspected 1-4 times a year. (For the record, ECG/EKGs are typically once a year.) One of the most important checks that gets done is the electrical safety check and electrode isolation test. Both of these tests make sure that no current goes from the line into the electrode/outside of machine (ie, into the patient.) This thing has nothing to protect whoever it gets hooked up. Part of me thinks this hack should be removed from hackaday for safety reasons, but the social Darwinist in me says that if someone is dumb enough to build it and hurts/kills themselves with it, even after reading the several warnings posted here, then by all means let him, it will only serve to raise the overall average world intelligence.",

You just need to convince your friendly local IACUC that you most likely won’t harm the animal, say 1 in 10,000 odds.Humans are a different matter entirely, though this project is reasonably safe assuming the subject /isn’t/ grounded.You can stick your finger in a 115v socket and not feel a thing as long as you are properly ungrounded. I’ve done it. Nothing happened and I couldn’t feel a thing. 0.15 microamps was the fault current, standing on carpet, dry-ish skin, dry air (Arizona), and 5 feet from the walls. The same goes for this project.In order to get a serious shock, you need to have current flowing. For that to happen with this circuit alone (no other current paths or grounds), that would require the inputs to the computer’s serial port to have dangerous voltages across pins which would subsequently have to make it through the opamps into the subject. Fairly unlikely, but not impossible. Even with a significant power line leakage current into the ECG system, no shock would be had without another ground return path through the subject.If you want to be safe, just run this experiment on a battery powered laptop. Preferably, put the laptop’s powerpack in the next room.Sorry for the long response. I deal with these issues daily and there is so much misinformation out there.by CKThrop",

It’s been a while since I’ve seen any new antenna hacks. On the
lumenlab
forums, [pitman2] started with a measurements from a commercial antenna and drew up a
set of plans
for making a decent antenna for OTA HDTV signals. Pictured is an antenna built by [squeeto] – it’s made from copper wire, synthetic building wood and cheap cooling racks. Thanks to [Protcron] for the tip.

[john] mentioned
this
on the
LCD LED backlight post
. Given the date on the posts, I was surprised that we haven’t seen it before. He replaced the CCFL lamp with 32 1 watt luxeon LEDs mounted on a custom copper water cooling block. The result is bright enough to be sunlight viewable in his car.

Part 2
of Ben Heck’s Wii laptop How-To is up. The first half is all about the little touches, wiring switches, extending connectors, etc. The second half delves into designing the actual unit. Some of the comment’s on Engadget seem to want a full bore step by step build, but fail to realize that he’s really giving them the gold. Very few designers give away their intermediate design steps – But I am reminded of some of the Star Wars movie extras…

PSP Downgrader For V3.03 Released

While I was on vacation, [Fanjita] and [Ditlew] released
a downgrader
for PSPs running v3.03 firmware. To get it to work, you’ll need an unpatched copy of the GTA:Liberty City Stories UMD. The hack should get you down to v1.5. It’s supposed to work on all current PSP hardware. Thanks to [wraggster], [Steve DiRaddo]. [Sean] submitted the same info [via
noobz
], but they don’t appear to have credited the authors. (Unless of course, the authors are part of noobz.)

Use this as a shopping guide.To “Ricky”:There will never be a way to run the downlaodable content without amending the PSP code with an external program.

I gather they had a small city network going there for a while using these transceivers. Unfortunately the big difficulty in laser comms is aiming, not modulation. There are more things than you think that can put your link out of alignment. You really need some sort of self-adjusting optics to do this for any length of time.",

Atari Punk Console

[
"Misc Hacks"

[] |
It seems Hack-A-Day’s resident snow bunny has run off to Utah and left me holding the proverbial bag. How could a heart broken hacker possibly console himself? How about the soothing sounds of the
Atari Punk Console
? Well… soothing is a subjective term, but the screaming, bleeping, fuzzy sound generated by this
simple circuit
is great. Since their first post on the Atari Punk Console circuit last fall, GetLoFi has collected
many different examples
of the circuit. It’s just a 556, a few caps, and pots so it lends itself easily to modification. The most recent post is
built in an actual Atari mouse
.

This one is fitting – I was just checking out Suunto’s sweet gps data logging watches today. [Steve Cholewiak] sent in his diy
GPS data logger
. It uses an old DeLorme tripmate – these were serial gps units that ran off of internal batteries. A PIC controller reads the NMEA sentences from the tripmate. Then it stores the track data to an EEPROM. The same serial connection is used to retrieve the data later on. [Steve] did a great job writing this up, the circuit is pretty simple and he’s provided all the information you need to build your own.

[Jared] posted the
latest version
of his remote control airsoft gun. The new one allows USB and R/C control. It’s got four seperate firing mechanisms, a laser and uses a pair of servos for motion… and lots of ammo. Whatever you do, don’t make fun of [Jared]. They’ll have video up on the site after a couple of days to save bandwidth.
(Just a note: embed
youtube
or
netscape videos
and you’ll have video and save your bandwidth.)

[Wayne] sent along this interesting read on
circuit board repair
. Even if you’re not uh, repairing, it’s interesting to get some ideas for modification techniques. Pictured is a DIP IC that’s been placed upside-down over the old one with a set of jumper wires. I can only aspire to produce solder joints that look that nice. Good stuff.
Just so the Unofficial Team-Hack-A-Day guys don’t crucify me, they too have been
making their own shirts
. Thanks [mastershake916].

"content": "I replace power jacks on laptop mobos regularly, and one problem I’ve run into a few times is when a lead on the jack has arced so badly that it the through-hole plating is destroyed. Usually this happens with the positive pin, which is mechanically tied to the center pin of the jack, so the through-hole plating is very important for strength.The site shows how to replaced one with eyelets, but I don’t have those so here’s a quick and dirty way to make your own. Cut out a tiny piece of thin metal, maybe 1mm wide by 1.5-2mm tall. Cut a notch (just one cut, don’t remove material) at the the center of the top and the bottom so that the left and right sides are joined by a small strip of metal at the center about the thickness of the board. Then fold the left and right halves toward each other so that they form a right angle.Now you have an eyelet (well, half of one, but it works), you can fold the ears on the top half outwards before inserting it into the hole. Be sure to scrape any insulation off of the landing pad if necessary. After insertion, fold the bottom ears outwards to secure it.",

[F00 f00] sent in his excellent piece of
iPod artistry
. It’s one of the most original iPod hacks I’ve seen yet. (Aside from his funky dock) I haven’t checked up on the latest iPod dock specification, but I’d guess he’s sending the command signals via the serial (TTL) interface with a microcontroller(pic/atmel etc) to encode the button presses.

"content": "Sooo Jeff (#7), This could be totally possible by using a (wired) ipod remote and connecting the buttons to the NES. It would be messy but possible. But what i would like to know is did he made a chip that converts the nes signal to ipod or used a ipod (wired) remote and just solder through the buttons.The Nes controller/connector is really simple.http://pinouts.ru/Game/snescontroller_pinout.shtmlIpod pin-out G2 and G3 generation. (other generations might be different of course)http://www.maushammer.com/systems/ipod-remote/ipod-remote.htmlSo next time before you “automatically assume” try to think if it is possible ( you lazy bastard :P ). That said i don’t know if this is real but i believe it anyway because i think that it is possible.Anyway if f00 f00 could be so kind to tell us what method he used i would be grateful. :)",

Over on the Ben Heck forums, moderator G-Force
made his own Hack-A-Day T-shirt
. I dunno guys, do we need to start selling them? In the past, our swag has been by give away only. Thanks [Marshall]
It’s been a couple of exhausting weeks since the deadline for the Design Challenge. I’m going to finish up going through the entries and we should have a winner sometime next week.

USB Keyboard Swap

"laptops hacks"

[] |
Laptops aren’t always the bomb/drool/mountain dew proof machines we wish they were. [TomTheGeek] was suffering from a loss of his I, 8 and K keys. Like a laptop Reaver, he
sliced out the old keyboard
and spliced in a compact USB keyboard. He likes the look, I’d probably whip up some acrylic spacers at the least and fill the exposed areas.

[Jason] sent in this nice
palmtop C64
(
cache
) project based on a
PSone
screen. Notable hacks: PIC 16F88 to encode rs-232 to
PS/2
keyboard output,
Atari
keychain joystick and a SD card slot (not functioning yet). The case was made of wood and laminated over with contact paper.

The C64DTV chip emulates an original keyboard internally, and does the translation for using a PS/2 keyboard.The disk drive port is also available, so you can connect a real Commodore floppy drive, or the floppy to SD adaptor. The adaptor was designed for real C64s so it works on those too of course.",

DC Entries: Six Channel PWM Modulator

[Waggy] submitted
this
handy device for his entry. It uses several 556 timers to clock a driver chip that drives the mosfet output. If you’re not familiar with PWM – think of it as a six channel motor speed controller, but far more flexible. [Waggy] did a nice job writing up the details on the board – definitely a strong entry.

"content": "Seems like massive overkill to me. How often does one need individual control of frequency for *each* channel, or PFM instead of PWM?It appears the way this works is that for each channel, the 1st timer runs in astable mode to produce the operating frequency, which triggers the 2nd timer in one-shot mode to produce the pulse-width. Unfortunately this means that you can’t adjust this to 0% or 100% PWM if needed. As the author noted, if you try to exceed 100%, “strange things” will happen – but I’d be wary of even getting close to 100%, as *twelve* timers and six mosfets banging away would make for a very noisy circuit!Personally I would have used *one* 555 to produce the frequency for all channels, and one comparator for each channel of PWM. Each comparator would have an input connected to the positive side of the 555’s timing capacitor (which produces a triangle wave with asymmetrical rise/fall), and the other input connected to a potentiometer’s wiper terminal, with the pot’s end terminals connected to VCC and GND, for duty cycle adjustment. With that, you could reduce chip count for 6-channel PWM generation from 6 to 3 if you use quad comparator chips (with two comparators left over), and also be able to set full 0%-100% duty cycle. Then I’d use the recovered board space to add some LEDs for visual indication of approximately what power level each channel is set to. Mmm, LEDs! :)Of course, I’m just being an armchair critic and didn’t take the time to produce an actual circuit, a great webpage and supporting files – so credit and props to the author for his hard work and sharing it with us.",

[Richard] pointed out this
mini-itx laptop
. The idea behind this particular design is to enable upgrading every component as needed. The case is aluminum, and the wiring inside is an exercise in patience. It’s not the first DIY laptop we’ve seen, and it doesn’t have batteries, but it’s the first I’ve seen with two internal hard drives.
Update: There is a battery, it just gets very little mention. It’s hiding under the DVD drive and one of the hard drives. Anyone know what kind it is?

[Ben Heckendorn] put together this
little beauty
on engadget. It’s not quite as over the top as the
XBox 360 laptop
, but there’s a reason for that. He’ll be putting up a How-To series covering the construction. If you’ve been pondering building a portable yourself, it’ll be a nice jump start for your hardware hacking skill-base.

PS3 DVR How-To

If you glanced at the PS3 and thought it was too expensive,
this
might help you justify spending your green. [ken_vs_ryu] put up a mini tutorial on running mythtv under Linux on the PS3 with an external USB capture device. When you consider the cost of a decent machine, video card and blue-ray drive, it’s not a bad deal. (I’m not sure how many Plextor ConvertX encoders you can run at once.) To get things working, you’ll have to thumb through the
Gentoo Wiki
for the details on setting up the ConvertX.

"content": "“it’s not a bad deal” might apply if you are looking for a DVR with Blu-Ray, but assuming you aren’t interested in BR (which is a fair assumption at this point) then you can get a stand-alone DVR for much less than this.If you were really into the MythTV route, you could still build a suitable (and smaller, if you used EPIA motherboards and such) machine for less. Which could still be updated with a BR or HD-DVD drive down the line, once they become more reasonably priced.I suppose it is cool from a technical point of view, but I would personally say that paying $600 for a game console only to turn it into a DVR is quite a waste of money, and highly impractical.“Hey! Let’s play Resistance! Oh…wait, the PS3 is recording Numb3rs…”",

[nicolas büchi] sent in his groups
latest project
at Zurich University. This innocent pillow interacts with the user based on current light conditions and proximity sensing(pressure). The project pages are in German, but the
video demonstration
explains it. I like the idea of a vibrating pillow alarm clock – as long as you don’t loose it during the night. It reminds me of
Clocky
– which is actually
for sale
now.

WL-700gE Serial Port Mod

The Asus WL-700gE is an interesting device. It provides NAS, streaming and routing services thanks to linux. In
their quest
to modify the WL-700gE to a more flexible platform, [Eric] documented adding a serial port to its not so spacious innards. (FYI, Standard serial/RS-232 signals are around
5 volts
ok, more like 12. I was thinking of the max 232/n variety) Asus was kind enough to provide through hole mounts and a TTL interface right on the board with console access already turned on.
I hadn’t realized it before, but the Siemens phone USB data cable is a nice cheap source of USB to TTL serial interfaces. Ironically, replacing the cable on the data unit was actually more difficult than adding the port to the router.

We hope they get 100% support soon. Their goals are not the same as ours (for instance, we want only a bootloader in flash), but obviously we want to cheer them on.So far the only patches I’ve seen to support much of the hardware for the Asus WL-700gE are against the 2.4 kernel. Our efforts involve porting to the 2.6 kernel.Brett Neumeier has made great strides. He helped me rebuild the Asus “GPL” “source” tarball, and flash it on the system. Also, when last we VNCed together, he was demonstrating how to get network booting to work so we can boot new kernels over the network (thus no need to re-flash for every change) and in that session we worked through mounting a root filesystem over NFS.So progress is slow, but non-zero.Wish us luck!",

Digital Rebel XT(350D) IR Removal
|
Will O'Brien
|
[
"digital cameras hacks"
] |
[] |
[ash] wasn’t satisfied with
these instructions
, so he provided a
complete how-to
on gutting a Rebel XT to remove the glass IR filter. This one involves pulling everything down to the CCD. Once the IR glass is removed, it’s replaced with some high grade glass from Edmund Optics. If you’re into camera modding at all, and own a Digital Rebel, the reference links at the end of the how-to are worth a read.

Add an IR filter and the results can look like a B&W photo with really odd correspondences between what objects produce black and what objects produce white. Sometimes there are colors in it too, depending on how the IR’s registered and how good the filter is at blocking visible light; those can look even more surreal.

[Andrew]’s

with his PSP is impressive. He used a webcam to watch for the appearance of the woodblock and used a small motor (probably serial or parallel actuated) to trigger the button on command. It’s a little silly, but it’s a good exercise for computer visual interaction.

Basic pseudocode to compare two images:Delta=0For X=0 To CurrentImage.Width-1For Y=0 To CurrentImage.Height-1Delta=Delta+Abs(CurrentImage(X,Y).Red-SavedImage(X.Y).Red)Delta=Delta+Abs(CurrentImage(X,Y).Green-SavedImage(X.Y).Green)Delta=Delta+Abs(CurrentImage(X,Y).Blue-SavedImage(X.Y).Blue)Next YNext XThe comparison that returns the lowest Delta (difference) wins.Also, sometimes it’s also useful to multiply each pixel/color’s Delta by itself, which gives higher “weight” to larger differences. This tends to filter out changes in the camera’s auto-exposure. For instance, red would be (same change applies to green & blue):Delta=Delta+Abs(CurrentImage(X,Y).Red-SavedImage(X.Y).Red)^2",

When the log comes up, I tell it to “remember” those points. When those points come within a tolerance of the remembered pixel values, it strikes.Darkcobra was right on:difference = abs( (RemR – CurR) + (RemG – CurG) + (RemB – CurB) )I also scaled the image to about 32×24 as to reduce the affect of static (essentially just sampled). Oh, and turned off the automatic gain control of the camera.I agree this is a silly project, but come on, like anyone is cooking for their family with a CPU hotplate (which is awesome)",

"content": "I’d agree that this application is rather pointless, but the technique itself is a good exercise which can be applied to something more useful. In fact, I’m going to be using it very soon.My favorite method of cooking a beef pot roast is as follows:1) Marinate roast for 24 hours.2) In a skillet over high heat, quickly brown each side of the roast in butter.3) Remove roast from skillet and set aside. Reduce heat, add some sliced onions and bell peppers, cook until softened.4) Add one cup of stock to deglaze pan. Put contents of skillet along with roast in an oven bag. Press out all air and tie off bag.5) Fill a crockpot 2/3 full of hot tap water. Place bag in crockpot, with the top of bag hanging out the side. Cover and cook at 147°F for 12 hours.The result is the best I’ve ever had – a deliciously seasoned, incredibly tender roast that’s nicely browned on the outside, yet cooked to a perfect medium on the inside……at least when my crockpot cooperates. It’s hard to dial in exactly 147°F, so my results vary. I considered solving this with an industrial temperature controller (cheap on eBay), along with a thermocouple and relay. I could even make my own controller with a PIC, comparators, or whatever. Then I realized I could hack a more versatile solution, with zero wiring or soldering, using only what I already own: a kitchen remote digital thermometer, a webcam, and the X10 system already hooked to my computer.The crockpot is set to its highest setting. The thermometer probe goes in the crockpot. The remote display goes in front of the webcam. A program reads the temperature from the display by determining which LCD segments in the numbers are on/off, and turns on/off an X10 appliance module hooked to the crock-pot as necessary. Voila – an infinitely programmably crockpot, which will cook my roast (or anything else) perfectly.See? A useful application. :)",

"Misc Hacks"

[] |
I’m heading west to do some snowboarding, so I thought I’d clean out the stuff I’ve been saving for you guys.
[Nagi Punyamurthula] sent his notes on
making PCBs
. It’s a nice introduction if you’re new to it.
[Monster] sent in his how to on
making a solder mask
He suggests using mcmaster-carr p/n 9709K61 (4 mil) or 9709K55 (3 mil) copper sheet.
[monster] and [uchobby] sent in using a scanner to
take measurements
on a PCB
[MoneyOx] sent in a
DIY Wii sensor bar
[Tom] sent in
Water cooling via swimming pool
. This made slashdot, but worth a look if you missed it.
Meta is
another
DIY segway, similar to [
Trevor Blackwells
]. (I’ve actually ridden that one) Thanks [Peter]
[Zack] sent along details on using a Nintendo DS
for VoIP
.
[Bruce] sent in his
shuffle in a hockey helmet
hack. I like the pseudo-dock he created for it.
This was on
engadget
a while back, but we’ve been getting lots of tips. Check out the
iPod in a gameboy mod
.
Finally, [everyone on the planet] sent in this Xbox 360
tilt controller hack
.
Thanks to everyone for their
tips
!

[Brian] sent in his Wiimote
hacking project
– he and his cohort used it to control an industrial sized robot arm. Then they armed it. Keep in mind that the sword is full size. [Aaron] ended up writing a basic pattern recognition program to get it to perform they way they wanted. Response time is a bit laggy, but not bad for a one-off project. I need my own industrial robot.

It’s interesting to note the stored movements and the wiimote movements were programmed separately…they decided what moves they wanted it to do (overhand, forehand, parry, etc) then one guy would ‘train’ his software to recognize how he would move the wiimote to execute that movement, and the other guy programmed the robot to do the movement. they could have used a figure 8 movement on the wiimote to do an overhand smash or a parry if they had wanted to.

Nike IPod Hacking

[
"ipod hacks"

[] |
Someone else’s apathy often becomes someones
motivation
. The guys at
Gordian Labs
got sick of trying to use Nike’s website so they dug into their iPods to find the data generated by the iPod+Nike running shoe add on. Then they put together a
handy site
for processing the data from the iPod. The site also accepts GPX data, so you can combine it with GPS data to track your runs and your routes. After they showed it to me, I prodded them and they put together a short
How-To
on getting the data under Mac, Windows and Linux.

Apple says that running with a hard drive based player would dramatically shorten the life of it so they did not include support for the nike+ thing. Covering their ass kinda thing.on the otherhand… is this really a hack? I mean the nike+ reciever just outputs xml files with all the info in them. This is basically just a program that interprets and does things with the data. I don’t think I’d really call it a hack to show hidden files and use them in a very similar way that nike already does. It’s cool, don’t get me wrong, you can do more in depth stuff with the data if you wanted or whatever (like adding the gpx stuff to it) and the nike+ website is kidna annoying sometimes.They have however fixed a lot of the issues with their site (they said it was mostly a high traffic issue). Now during the peak hours you have to click on things twice, it’s very usable. I use the nike+ site, I’m new to running so it does everything that I want it to do.",

Part one
of Ben’s Wii Laptop How-To series is up. Ben spends it discussing gutting the Wii, starting up his CAD process for designing the enclosure and makes the thing even smaller than it was before. Because the Wii is so small to begin with, I think alot of people assumed that he just slapped it into a case and added the display.

Concrete Cast Speakers
|
Will O'Brien
|
[
"Misc Hacks"
] |
[] |
[Markus] sent in his
5.1 concrete speaker project
. Each speaker is cast from a single piece of concrete. The inner cavity is created using the dear old lost-wax technique. The writeup is in german, but the process is pretty clear.

The guy had a “normal” sub enclosure in the trunk, built out of 3/4″ MDF, properly tuned, ported, etc… After the box was built, one side at a time (6 pours) he poured like an inch of concrete in the box. Of course the tuning and porting was done taking into account the thickness of the concrete. Ended up with a bigass heavy box holding a couple of 12s, and it seems like he “had to” beef up the rear suspension a bit.They said higher density enclosures sound better. Mostly I figure the project was more for bragging rights, since that much energy spent in sound-proofing and vibration-damping in the car would have probably been more effective.",

In a guitar or violin (or a drum, for that matter) resonance is good. But in a speaker, the only thing resonating should be the driver itself, and the air inside the cabinet. If the walls of the cabinet resonate, you will get unwanted muddiness, or unwanted peaks in the frequency response.The spikes in the bottom of the subwoofer are standard issue on audiophile speakers (and most DIY jobs). They are said to “limit floor coupling.” That is, have the least amount of contact with the floor as possible so that the floor doesn’t pick up bass frequencies and resonate with the drivers.I personally think the paint job is pretty cool, by the way. Certainly not a color scheme that will please all tastes, though.",

[Joel] sent me
a tip
where I discovered this fun hack. It reminds me of the old pencil lead resistor trick. It looks like
Ableton Live
has been inspiring quite a few
original controllers
.
From the post: (Myspace doesn’t seem to have individual post linking)
“If you REALLY want to do this, the code is
here
. It is sloppily written in PASM for the Ubicom SX microcontroller running at 50Mhz addressing an ADC0808 (
datasheet
) 8 bit parallel ADC, because it’s the year 1993.”

[Keith]’s cousin gave him a LCD with a noisy backlight. He decided to
replace it
with a series of high output LEDs. He sourced some locally in the form of cheap LED headlamps from an auto-parts store. The results look pretty good – and the write up contains this gem: “…One [LED] also exploded due to an accidental overvolt. Shot me in the Chest. Panel okay though” Nice work.

Its not like its a really high colour temp, more like just an off white.I did some current readings before I attempted a rewire and these are nothing like the 1 Watt superbrights. The total current draw at 3.2V before some LED’s died was 600ma (which has all been either a result of me putting 12V over 2 in series which was more of a mistake or because when i was solderin the wire near the plastic bodies they randomly decided to stop working, i assume because i overheated them) None have died as far as I can tell since I’ve been running the monitor with the wall wart and its been runing for hours today.Right now at 3v its 404ma and with 4.5 its 765ma, so 3.5 watts max.Since this was more of a test, I’m glad people’s main thing have been my lack of caring on the electrical side rather than the project itself.

Optoisolated Xmas Light Control

[buzzkill] brought
this
crazy christmas light controller to my attention. The hack is pretty neat. The potiometers in several standard dimmers were replaced with photo-resistors. When squares of the screen are lit, the dimmer is activated. In essence, it’s a cheap optoisolator for controlling AC power. The software that generates the interface appears to be sound actuated once it’s programmed by the user.

But it is hard to scale in that as you can see from the photos that as you add dimmers and outlets it takes up a lot of room. He also mentions that variations in the dimmer components and the photo-resistors themselves lead to inconsistant results. Some lights don’t turn on. Some never turn off. For a more scalable solution that is still DIY check out Computer Christmas. Many etch their own controller boards and the forums are pretty active with new circuit designs and board layouts. The easiest solution is on/off only. But they are quickly working on a dimmable option that should be ready in time for christmas 07.",

) It’s more of a guide to modding the NES for more user friendly operation. Emulators and a USB game pad usually do the job for me, but there’s nothing quite like the original hardware. Hmm, I just ran across my NES advantage joystick earlier today.

Plus I’m Nostalgic!",

"content": "Licking? Yeah, no good.I would agree with #3 about the angle bit, as the cartridge loader didn’t do a good job of keeping your cart’s contacts from scraping upon each pop-in/pop-out routine.As far as cleaning, don’t blow and definitely don’t lick – both of these methods get tiny bits of moisture on your cart’s contacts, which could eventually lead to mild, but nonetheless detrimental, corrosion – or so the guy at a local game store told me once, but who knows – I’m sure licking gets things a little more moist than just blowing.A recommended way of cleaning is to put a paper towel around a car key and using that to ‘scrape’ the contacts on either side of the cart’s contact strip. Make sure you aren’t too rough, as you might rip the paper towel and end up scratching up your contacts.If you’re brave enough for this mod, then kudos – if it doesn’t work out or you don’t feel like going through the trouble, you could search for a top-loading NES. I got mine 6 years back or so at a Babbage’s for somethingl ike $12 and it has worked great ever since.",

You can also use the cleaning kit if you can still find one it was a cartridge with fabric that you put cleaner on and the inserted into Nintendo.WD40 could cause shorting pins as well as licking and after a while will build up a really messy yucky gewy fim inside your machine and on your games.The pin thing sounds interesting to try I have a few extra machines might try it",

JScanlogAlert Hardware Network Monitor

[Jose] sent me
this
interesting little project. JScanlogAlert is a combination of hardware and Java software designed to monitor your network for undesired traffic. (looks like fun for capture the flag competitions.) The hardware is simple – the data lines of a parallel port are used to trigger LEDs that signify the network state.

This isn’t a hardware network monitor. Its a software monitor that then sends data to the printer port. If you wanted to dedicate a machine I guess you could call that your “hardware network monitor” because its a dedicated machine.This is very similar to other “Computer controlled ____”s with different software. Athough it is a novel use, I personaly have nothing wrong with a simple shell script, cron, and sendmail (either way I have to check something on/by the computer).",

Cheap Function Generator
|
Will O'Brien
|
[
"contests",
"Misc Hacks"
] |
[] |
I’m inclined to put up [nuxie1]’s
function generator how-to
because he also submitted a very nice Design Challenge entry. The generator is based on the cheap XR2206 IC which will generate functions at up to 1Mhz. Definitely handy to have around.
His Design Challenge entry was really over the top. It’s
another USB PIC programmer
, but he laid out three different desings. A full-on SMD, a home build SMD and a through hole board. Nice work.
We’ll be announcing the winner of the Design Challenge in another week and a half or so – we got quite a few entries and it takes a while to really review them.
