Cathode Ray Tube Leads The Way On This Bot

[Daqq’s] latest creation is this little
robot with a CRT mounted on the front
. Obviously ‘why?’ is the wrong question here, but we know this is right up his alley considering his propensity for the less common like this
plasma ball Nixie tube
. The solidly-built bot uses two stepper motor controlled wheels and an omni-wheel on the front to create a trike. An ATmega128 controls the system but the real story here is the CRT. It requires a hefty voltage regulator for the -600V to +200V the Tungsram DG7-123 tube needs. Trouble along the way ranged from dealing with stray magnetic fields from the power supply, to mounting the fragile tube itself. Take a look at his detailed writeup linked above and join us after the break for the demo videos.

Great idea!@everyone: Xrays are not a problem, given that the acceleration voltages are max 800V (worst case scenario, the farthest cathode to the deflection plates @ max.).@polymath: The wavy effect is nice, and I’d keep it there. THe problem is, when the frequency from the transformers is not a multiple (or somewhere around a multiple) of the display redraw frequency, it becomes illegible – it begins jumping about.

In the ongoing quest to make the Force Trainer useful [Hunter Scott] developed
a music composition platform for your mind
(channel Jack Black’s voice for the last half of that sentence). Using the
Force Trainer’s serial port
[Hunter] feeds the data stream into a computer via an FTDI cable and uses Processing to make the music. It’s good, and the demos on his site are worth the click, but we still can’t get enough of
the shocking video
from back in March. But we digress, let [Hunter] walk you through his setup in the video after the break.

[Daniel Paluska] is getting away from the point-and-click by
editing videos from the command line
. Using the free open source software packages FFmpeg, Imagemagick, and Sox he produces new clips from multiple videos with effects like overlaying, slicing, and assigning each video to a different quadrant. The last option would be useful for displaying different angled shots of the same thing all at once but we’re sure you can find a way to use them all. He is using shell scripts to automate some of the process but the commands are still easy enough to understand if this is your first foray into these tools. After all, great video production will go a long way toward becoming an
Internet sensation

Additionally, you can type “alias *” and have every file in the current folder processed at once, without having to copy all of the files into a specific directory.This also allows you to run the same aliased script on 2 separate projects in 2 separate locations without having to have 2 separate shortcuts.Bonus, you can use ssh/telnet/logmein/vnc/psexec/whatever to run an alias from anywhere, and monitor the progress without needing a ton of bandwidth.Bonus2, your desktop isn’t littered with 1000+ shortcuts for scripts.For me, both of the above are important. I work on a lot of very different projects, and i’m extremely lazy. I process about 3hours of audio a week, maintain +100 systems, +50 servers, handle burning update disks for several of our products, and edit video from time to time.If I had a shortcut setup for every one of these batch jobs, (or god forbid, no scripting at all) I wouldn’t have enough hours in a day to do all of this, and it would take ten minutes to find the icon for anything.",

Modern Car Data Systems Lack Security
|

"CAN",
"can-bus",
"odb-ii"
] |
Tomorrow
a team of researchers
will present their paper on
Experimental Security Analysis of a Modern Automobile
(PDF) at the
IEEE Symposium on Security & Privacy
. Much like the
racing simulators
we’ve seen they’re exploiting the ODB-II port to get at the vehicle’s Controller-area network, or CAN-bus. We’re not surprised at all that they can display custom text on the dashboard display or read sensor data from the car. What does surprise us is their exposé on how truly unsecured the system is. It seems that access to any device on the CAN-bus gives them unobstructed control of the car’s systems. Any device can send commands to any other device. They’ve even found a way to write malicious code to the car’s computer which can be programmed to erase itself in the event of a crash.
Much like RFID the security risks here are basically nill for the vast majority of consumers. We just find it a bit surprising that there’s apparently been little thought put into fortifying the communications between the safety systems such as the brakes on the vehicle. For instance, team experimented with sending random packets over the CAN-bus and stumbled across a way to lock the brake on just one wheel. To us it’s conceivable that a malfunctioning device on the network could start sending out damaged packets and cause a dangerous malfunction like this one.
The 14-page PDF linked above is a page-turner, check it out on
your hacked ereader
during lunch.

The only risk lies in the bridge, and that is generally uncommon. How many of YOU have OnStar. Likewise, @brad, you can’t just connect to the OBD port and upload code into an ECM, not how it works. The security risk is not on the local communications, it’s purely in OnStar and related systems. Even then, it STILL requires physical access.

Honestly aside from plugging directly into the OBD port, or an emergency cut-off signal (like those used in anti-theft systems) there should be no way any external system should have any control what-so-ever of the self-contained engine control systemSabotaging via OBD port based reprogramming is much much much more difficult than any of you think it is, yes the protocol is simple, but in order to do anything worth while would require extremely intimate knowledge of the specific model of computer and engine that the vehicle uses.In general we shouldn’t really fear these kinds of attacks anymore than fearing someone cutting our brake lines, or sabotaging our cars in any other non-computer related way…. if you’re really worried about it, then install a hidden switch on the OBD serial wire to leave it turned off when you don’t want people plugging in… most WELL DESIGNED cars I’ve re-programmed actually required several jumpers to un-write-protect the computer module anyway.",

The head units in GM cars are on the low speed network. They don’t bridge.3.) The OBD2 port on GM cars exposes both high and low speed CAN (GMLAN)4.) The OBD2 port is the easiest access point to the bus. It is NOT the only. There are plenty of connectors that are accessible from the outside (under) the car.5.) Cutting a brake line is fine and dandy, but I bet 99.9% of people will notice before they get up to speed. Being able to kill the brakes remotely, while at speed, is dangerous. Or locking just ONE of the tires (prob more dangerous).6.) GM uses the SAME PCM (they’re not called ECUs) in every single one of their vehicles now. Literally, the same part number, just different firmware.The point is, the bus is easily accessible, easy to muck with, and with a few hundred dollars, a visit to Dealextreme and sparkfun, you can have a GSM connected canbus controller that’s capable of doing some severe damage.Or, you can do cool stuff, which many people are right now.To add to that, OnStar is making it’s way into other brands other than GM. GSM cracking isn’t rocket science anymore (a few grand in hardware does it), so it can start to get pretty scary if someone “evil” got any ideas.**I own a GM vehicle with everything on the bus and have played with it. I will be making a few modifications to my car that sit on that bus. I’ll also be changing the factory PCM code (HPTuners) for better performance.",

"content": "Yeah, you can get stupid results by doing stupid things.Better read the CAN specification about the ‘malfunctioning controllers may send malicious frames to the bus’ issue. A CAN controller is required to go error passive (i.e. not transmit anything) once there are to many error-frames, which would involve having two controllers send the same message id at the same time. And the kind of software bug you need to get ‘valid’ frames (accepted by receiver) to be sent by a defective controller instead of the original controller is intentional wrongdoing.I like the explanation that having access to the car makes no difference for the malicous effect it may bring. One could also e.g. sensors, brake pads, tires or the engine to do something in the wrong situation or by an RF signal. Or disable the airbag by modification (without the driver noticing it). In any case there would be an extra device or detectable modification involved to achieve this.I can imagine that these systems are set up to work as good as possible. But only in an unmodified environment and still possible to detect errors of the usual kind, which can include other controllers sending invalid data.There is probably no difference to other hacks and security issues like in a plane, a train, the traffic lights or a lift? Did you guys think that all these systems are strongly secured in their functionality against intentional wrongdoing on hardware level? No one will pay for this kind of development unless it is an everyday problem. If it can be shielded or firewalled then this is the solution of choice.It is like the lift stalls and someone modified the brakes intentionally once he had access to it. So what do you do? Developing brakes that can not be set out of order is impossible. You can only install a lock in the door and make changes detectable.Doing something useful with the self-owned car may be a good thing, but you still need to pass the technical check and the show stops when people get injured or killed. Sending ‘random frames’ via ‘extra’ equipment on the CAN-Bus while driving is intentional wrongdoing and people could go to jail for it. This is not case-modding of the home pc.The problem is, that these modifications are too complex to be identified by just a look at the ‘new part’ or reading a sheet of paper. So what are technical check organizations supposed to do? Forbid them all? Probably.wbr",

[Elgatoandaluz] has posted this guide on how to
tear apart a standard optical mouse and build a custom trackball
. He’s using a ping pong ball , mounted above the laser as the trackball itself, which seems like it would be a little lite, but functional. The case is scrap cardboard. We really like that you could toss this together relatively quickly and have a custom layout. He recommends using
Sakasa Mouse
for inverting the axes and
X-control for mapping the buttons
(direct download).

Magically Repair AVR Chips

If you’ve ever spent time working with AVR microcontrollers you’ve probably set the fuse bits incorrectly at least once. The
ATmega fusebit doctor
will automatically repair the fuse bits and get you back in business until your next mishap. The ATmega8 that powers the device has the chip signatures for the ATmega family stored inside so it will automatically detect which chip you’re trying to ‘unbrick’. From there it looks up the correct fuse bits and resurrects the sick microcontroller. This is useful in recovering a chip that has serial programming disabled, used the reset pin as I/O, or just enabled an external clock without the necessary hardware to deliver on that feature.
This magic is taken care of by using High Voltage Parallel Programming. We’ve seen HVPP used in
the Arduino rescue shield
and it is a valuable
feature of the AVR Dragon
, our favorite AVR programmer, as well as others. Still, you can hardly beat the ease of plugging a dead chip into this board and pressing one button. Oh, did you brick a member of the ATtiny family? There’s

The 555 was a saver as always. Perhaps a LPT-based version would have been ready in less time.It is worth noting that I never had (or even used) a commercial programmer except a Vantis/Lattice JTAG cable. ISP is a popular thing nowadays, so unbrickers like this one can significantly improve economy. However all is well until you run into necessity to use another microcontroller in the unbricking setup. The solution looks… not elegant :) Of course when most of my playground AVRs will need a helping hand, I’ll still go with one of these projects. It’s nice that there is so much of them.@op: a few blank AVRs and triple-checking things can fix that, too ;)",

Maybe if you had a bunch of preprogrammed AVRs to recycle? Or if you use low-voltage ISP in production and have occasional emergencies where a bunch of units got programmed with the wrong hex file before anybody realized they were failing tests, and you don’t want to train technicians to use AVR studio? Or maybe in an educational environment where you just don’t want to go through the exercise of introducing anything more complex than fix-it-with-this-thing-with-a-button to people who are getting started with the Arduino?",

But if you have some questions i will be glad to help :)Ryan – THEORETICALLY it’s impossible to reset the SPIEN fusebit in SPI(ISP) programmer – but in practice you can do this after few attempts. Here is the nonsense: SPIEN not, but RSTDISBL fusebit is accesible trough low-voltage, you can write your code, and disable reset. Both make chip deaf for ISP. I think RSTDISBL should not be accessible by ISP too… I don’t know how it is in PIC with clock-select fuses, but here you can set wrong clock source (eg external RC or generator) and without it uC will not work and will not programm.Brent – as you say, this circuit is rather for users who plays with AVR occasionally and have couple of blocked chips – it’s cheaper to make this circuit and recover them, than buy new chips.To everybody who complains about DIP sockets – Why not ZIF? For now device supports 76 AVR Atmega and Attiny chips, look at datasheets and see how the pinouts differs. To support all pinouts, there should be 9 or 10 slots – now calculate how much you spend on 10 x ZIF slot – this is project must be cheap – instead of spending that money its better to buy real HV programmer :) So i used DIP.Always you can make adapter with 1 ZIF slot, and wire it up for the right AVR that you want to cure – it’s not that stupid – there will be no need to make several adapters for different chips…OR use the breadboard, wire it up (from 20pin adapter connector) for single chip fix. HVPP pinout is described in any AVR datasheet at “memory programming” -> “parallel programming” – its very simple to connect by names on PCB. BUT if someone is too lazy to check HVPP pinout in datasheet, go and buy new uC.For soft updates check my site, i plan to add HVSP adapter to support those tiny 8pin chips too – so you get 2in1 doctor :)Also i will be adding adapters for other mentioned uC’s, also i add description which chips fit in which slots.If someone make adapter for other chip, i will be glad to publish it on site :)Regards :)",

Thanks to craigslist [Chris] got his hands on a soda vending machine circa 1977. It still worked just fine (because things were still built to last back then) but he wanted to
add some super-secret upgrades to the beverage dispensary
. Two capacitive touch sensors were added to override the need for coins for those who know where to caress the beast, and iPhone support means that frothy beer is just a touch away.
The capacitive switches are using the same
QT100 chip we saw in the game of life
from last year. The whole thing runs off of a Phidgets board which we’ve seen in the past
using iPhone control to launch rockets
. See a demonstration of the features in the clip after the break. We’d love to do a hack like this but the problem is once you’re done, you’ve got a vending machine sitting in your house.

"content": "Nice project, until I saw that they were donating part of the proceeds from selling the machine to Kiva.***Microfinance institutions are decidedly evil. The basic premise is that these are corporations, not charities.Problems:-not a charity-parasitic institutions associating themselves into the act of charity-high interest rates-kiva farms out loans to other groups within countries-no data on collections or defaults-teaching that relying on debt is OK-huge amount of money spent on marketing-success stories falsified-western power structures, control, etc.-spiral of debtSam Daley-Harris –“…there is still a bit of deception in the notion that the moment that a loan is funded, the client in Kenya or Cambodia receives his or her microloan with those particular dollars. Indeed, there are real people receiving real loans to start or grow real enterprises, but if a client in a remote village qualifies for a loan, the MFI will not likely make that client wait for the Kiva lenders to put up that last $25. Said another way, loan funds are fungible, and a larger MFI on Kiva’s website will use Kiva’s loans as one important source of their lending pool, but it’s not actually those precise dollars going to that precise client.”And“…for September 2009, only 4.3% of loans were disbursed after Kiva users had fully funded them through the site. And probably some of those the local lender had already committed to make before Kiva users had funded them. And in a new report on what happens to investors when microfinance institutions collapse, Daniel Rozas computed from data on kiva.org that the failure of just three lending institutions caused 93% of all Kiva defaults to date. No doubt many of those institutions’ borrowers were faithfully repaying at the time of collapse. Conversely, if a borrower defaults, the lender will often cover for him in order to maintain a good reputation on Kiva. So whether you get your money back as a Kiva user depends overwhelmingly on the solvency of the lenders, not the borrowers.”The premise of Kiva is a sham.Another thing about micro-financing is that make things extremely unstable.Back in 1999 in Nepal, there was huge speculative market for growing organic fruits and herbs. Things like strawberries and coffee to be produced in a small scale so that it could be exported to niche markets in the west.The ease of access to credit and the heavy marketing of organizations like Kiva made it seem like taking loans would be a win win situation. Poor farmers got duped into taking out loans by either seeing an ad, or be some entrepreneur who used the farmers clean record to take more loans.But since no infrastructure existed to export the produces, no proper expertise for growing the products, and the west never wanted products from the Nepali market anyway, every single one of those loans got defaulted. The farmers got saddled with debt, people killed themselves, entire villages economies gone. But, hey, you gave them credit right? Its their fault for not using it properly, plus you get your cash back anyway, no big loss.Basically, microfinance institutions as they exist now, serve no other purpose than to create speculative bubbles. Organizations like Kiva dont provide any support, no education, no explanation other than some brochure and one on one talk with a sales rep. Problem doesn’t lie in the fact that people have no access to credit, the issue is that 3rd world countries cant penetrate the world market, cant compete, and dont have the resources (not credit, i’m talking expertise and knowledge), to compete in the messed up capitalist system.Its small things like this, no one will ever hear about or will ever record becasue it will be scoffed off as some ill informed speculation, when the true culprit is the presence of the MFI’s.Amusingly Thomas Dichter from the CATO institute (yes that one) has written books critical of microfinance, which should be a massive warning signal in when the intellectual bastion of libertarians thinks its problematic:http://docs.google.com/viewer?url=http://www.networkers.org/userfiles/Microcredit%2520All%2520Dressed%2520Up.dochere’s an article from forbes (which is you know, forbes):http://www.forbes.com/global/2006/1113/026.htmlBloomberg article on predatory microlending in Mexico:http://www.businessweek.com/magazine/content/07_52/b4064038915009.htm?chan=searchWhy can’t we have microfinance that more honestly presented itself as a business transaction rather than clothing itself in the language of charitable giving?***",

If a machine is opened, they ship it back to the design group and figure out how the thieves got in and redesign it to eliminate that vulnerability. It is inconceivable that they would allow a hole that big in their security.So no, I don’t believe that any machine out there in the wild can be so easily induced to dispense free product.

Building An Oak Telescope

"Misc Hacks"

"optics",
"telescope"
] |
You might not think about the finish of your homemade telescope but if it’s build from solid oak you probably should. [Gregory Strike]
built this 8″ telescope
a few years back but just posted about it a few days ago. The optics are quite expensive but the rest of the build was done dirt cheap and he did a great job of it.That includes taking care to finish the oak boards that make up the octagonal body of the instrument.
This is much more approachable for the average hacker than something like the
22″ binocular build
(or going way too far and
building your own observatory
). [Gregory] developed his design after looking at a couple of others. If you need a bit of a push to get started
check out the telescope resource we ran across
in our days of Internet infancy.

Slight expansion along the length of the telescope tube results in a small shift in focus, but no other significant errors. Shifts in the tube radius will generally keep a centered diagonal centered, and cause no real additional problem.It’s common to use cardboard tubes used in the concrete industry (“Sonotube”, and related products) as telescope tools. Despite the apparent cheapness, it’s actually a fine material for scopes of this size. It’s cheap, easy to paint, strong enough, and easily available. Yes, you have to waterproof them (I like to use a durable poly floor paint) and I wouldn’t leave them out in the rain or in a high humidity environment, but would you do that to a camera?One of the past members of our workshop, Phil Alotis, did a similar scope in years past. It appeared in Sky & Telescope, and was called Christine. You can see it on the left here:http://www.whiteoaks.com/jane/Christine/glacier.jpgIf my memory serves, his wife was the motivating factor, she said that if he was going to store the scope inside, it had to look pretty. The resulting scope is beautiful, but massive. I think the mass means that it cools relatively slowly, which can be a disadvantage as well.

Tweet-a-Watt Now Speaks To Google Power Meter

"tweet a watt"

Hackaday’s own [Devlin Thyne] has been working with Adafruit to come up with
a way to use the Tweet-a-Watt along with Google Power Meter
. Back in March we put out the word that
Google had unveiled the API for Power Meter
and [Devlin] is the first we’ve heard of to come up with a way to use your own equipment with the service. You can build your own or
use Adafruit’s kit
and the data pulled from your energy use will be nicely displayed using the big G’s tools. Right now there’s only support for one Tweet-a-Watt but we’d image this will evolve fairly quickly into a much larger house solution. Head over to
the Tweet-a-Watt code page
to get the source files for this project.
[Thanks PT]

[DeadHP1] has been rolling and optimizing his own
Ubuntu distributions for the ClarionMIND
. He calls his work Mindbuntu and he’s squeezing out quite a bit of performance from the mobile Internet device. The video is running at 800×400, as well as wireless, sound, Google Earth with GPS support, and even compiz. Install the image using
unetbootin
to place it on a thumb drive and you’ll have Ubuntu 9.04 to go in no time.

This
automatic fish feeder
didn’t take long to put together and it allows you to adjust how much food is dispensed. [Gagandeep Singh] built it around an Atmel AT89C2051 microcontroller. Like many of the
automated feeding systems
we see, this uses a character display and a few buttons for the user interface. We’re always curious at how they mechanically dispense the food. In this case, the motor seen at the left pulls open a sliding baffle which is pulled closed again by rubber bands at the right. It’s a bit more involved than
the last fish feeder we saw
, but your guess is as good as ours on which system works better.

Inside the drum was a tube with a hole in the side acting as an intake, and the opposite end was open to dump into the tank. As it rotated twice daily, the intake hole scooped up some food, and the outlet dumped it into the tank about 6 hours later.It was kind of tricky to set the appropriate amount of food and still have confidence that you weren’t going to starve the critters.We solved all those problems when we gave the aquarium away to a nephew. :-)",

Urine A Candidate For Energy Independence

We thought we were supposed to have fusion-power for our DeLorean by now but it perhaps
urine-power is just around the corner
instead. [Gerardine Botte] has been working on creating hydrogen from urine, the world’s most abundant waste product. The voltage needed to break apart the urea atoms is less than half that of water, and the way we see it, you’ve had the added benefit of already using the water once before creating the fuel. [Gerardine] also makes the point that urine has phosphorus in it which could be another useful outcome of the process because it is needed as an agricultural fertilizer. Does this mean that you can repay your designated driver by fueling up his vehicle after a night at the bar? It’s probably better than
doing the same for the battery of your cell phone
.
Hackers produced the first
vegetable-oil powered vehicles
so we’re throwing down the challenge of producing the first pee-and-go automobile. Good luck and wash your hands when you’re done.
[Thanks Peter]

But you still gain energy when it’s done on an industrial scale.Also gasoline is orders of magnitude more energy dense than hydrogen, which makes it convenient for mobile power. Whereas already mentioned you have to compress H2 to multiple thousands of psi in order to get the same range that 15 gallons of gas will get you. Never mind that under those pressures hydrogen reacts with most commonly used metals and causes ‘hydrogen embrittlement’ so you have to use fancy(read: expensive) reinforced fiber tanks in order to contain it long term.Neverminding the possibility of combustion should the tank leak, what about when some drunk flips his SUV 17 times on the highway, current gas tanks will gurgle out their contents lazily. What do you think will happen when a tank holding back 5kpsi hydrogen gets a crack in it. Even if the tank its self doesn’t fragment(there are some people who claim to have developed a tank that resists this) all that compressed hydrogen is gonna vent somewhere in a hurry.",

Try to drill a hole in lets say propane tank under pressure, gas wont escape thought small hole instead it will rip apart whole tank cutting off both you arms and head from torso, safer experiment: try to make a hole in inflated balloon without destroying it.There is no point to use hydrogen, you lost a lot in producing it from electricity, and it hard to store. The only advantage over accumulator is ability to use it in gas engine. And it worse for environment than gas, just think where electricity is coming from and since there is more loss in conversation more material is needed and more waist in production.For now before some super capacity batteries get invented the only reasonable alternative to gasoline is natural gas which by the way was used for long time in some Soviet cars.I will repeat again – hydrogen is scam directed at government by “researchers”",

[vimeo=http://vimeo.com/9661763]
[Robb Godshaw] put together a pencil production line for home use. The whimsical assembly line starts with a graphite rod and extrudes clay polymer around it. From there it’s down a conveyor belt to get stamped and then into the oven made from a hacked toaster. The final step is to cut out a plug of eraser and attach it to the back-end of the pencil. This low-speed assembly line reminds us of
a Rube Goldberg machine
with all the wasteful steps cut out.

Anyone who has tried their hand at RPG Maker 1 (or any text input with a controller) knows how difficult it can be typing long paragraphs into the console. [Thutmose] is here to save the day with
Kupid 1.0
(2.0 in production). A PICAXE takes ps/2 keyboard input and converts it to a series of d-pad button presses for PS1 and PS2 controllers, providing
quick data entry
compared to the previously monotonous task.
We’re happy to learn that the
source code and hardware
is released, meaning it has the potential to be easily adapted to any controller/console.

While I like the PC makers better personally, for a number of reasons, it’s still charming to see people use the old console makers – akin to someone writing games for a C64 today.Users of RPGM like the software, like to experiment and push the limits just to see if they can. It has it’s own character and intangible qualities that you just don’t get with XP or VX, or the other makers.I created Kupid to help support these people, so that they can continue doing what they love.@Nick McClanahan – The wire is hooked up to the button traces on the PS1 controller PCB. For each button press, the PICAXE uses corresponding darlington array pin to bring the trace to ground, which the PS1 MCU reads as a button press.@Henri – Version 2.0, that I’m working on now, will use an MCU to emulate the PS1 controller, so it will hook directly up to the PlayStation, rather than piggy-backing off of a controller.But stealthmonkey is right. It was a heck of a lot faster and easier for me to solder to the button trances that it would have been to emulate the controller right off the bat. I learned a lot doing it this way, and consider it a stepping stone to more complex projects.@Giulio – Cost is a major factor. I wanted Kupid to be as cheap as possible, and making it USB compatible would be expensive. Further, USB keyboards use more power than PS/2 keyboards, and there is very limited power to work with.",

I want to share with you the latest news about MTV Video Music Awards.Since MTV revived its highest honor — the Michael Jackson Video Vanguard Award — at the network’s annual Video Music Awards in 2011, it has gone to Britney Spears, Justin Timberlake, Beyonce and Kanye West, a lineup of artists who, from the beginning of their careers, understood the power of a well-executed music video.That’s partly because of their ages: Like MTV, Ms. Spears, Mr. Timberlake and Beyonce were born in 1981, and Mr. West was born in 1977. They’re old enough to have lived through the era in which MTV dominance was integral to a pop star’s ascendance. Even if the channel’s relationship with music was in decline during the peak of their own careers, they understood its legacy, and executed top-notch videos accordingly.Please move topic if forums “http://hackaday.com/2010/05/20/keyboard-input-for-playstation/” was not chosen correctly.",

This
art-meets-robot has the grueling task of standing on one foot
all day long while
other robots get to bend
to their heart’s content. It balances on that single point by adjusting its center of gravity with six pendulum-like appendages. To make the system more like
the Borg
, each of those six modules shares sensor data with the rest and work together to keep the unit upright. Give in to loving the design because resistance is futile.

Arduino Based EATC Replacement

] |
The Electronic Automatic Temperature Control Module on [Dan Mattox’s] 2000 Ford Taurus bit the dust. The junkyards in the area didn’t have a matching replacement and a new one is pretty hard to come by so he
built an EATC replacement from an Arduino Mega
. It includes a solenoid controller board for the vent selector, blower control, and new switches to control the power windows. He’s got the system up and running which is important because after removing the broken EATC the car was stuck blowing 90-degree air at full blast. He’s put together a demo and an installation video which we’ve embedded after the break but there’s also
a photo album
you can page through. The sketch that we developed to control the system is
up at pastebin
so get it while it’s hot.

[Chris Farnell] and [Michael Helms] are the brains behind this scary looking piece of machinery. It is a
Coil gun, mounted on a turret, that is controlled over WiFi
. If that wasn’t scary enough, they have rigged it to their iphone/ipad for remote shooting. Though it looks bulky, you can see that it is surprisingly responsive in action.

We’re going to straight out agree with [Pete] on how surprisingly quiet doorbells are now a days, and if we had it our way we would put his
Lunkenheimer train whistle doorbell
in every home*. The setup he uses is surprisingly simple, opting for a pre-built wireless doorbell that signals a microcontroller which in turn drives a relay and solenoid. While he does include a video, we felt it didn’t quite show the
intensity
of these whistles.
*HaD is not responsible for hearing loss and subsequent melted brains.

Yes, it *should* be done, but on a tank that size, it’s more than likely overdesigned, since most people that run those little compressors don’t take care of them too well, and they’re much more prone to rusting-out due to not draining the tanks. The worst possible way that tank would fail is the elliptical cap blowing off or the lengthwise seam failing, but it would more likely just shoot off the steam whistle and vent, if it did fail.For anyone wanting to do this, if you’re concerned about safety, hook it up to the standard air hose outlet, just remove the 1/4″ connector or whatever is on there, and screw directly into the tank.

Kaossilator On The Cheap

We recently stumbled on a way to turn a regular laptop into a
poor man’s Kaossilator
. Using the touchpad of your laptop, some
PureData
software,
Touchpad2MIDI
and a couple custom patches, [zenpho] has set everyone up to create that crazy electronic music that kids listen to these days.
But what was that? You cant afford a whole laptop, and need to make this happen on an even tighter budget? Oh,
we’ve got your back
. Using just the trackpad and an Arduino, [Bastiaan] has created a basic PS2 to Arduino to USB link which can be parsed by your
favorite
language

into a working MIDI interface. Good news for all the lazy hackers out there, he’s planning on swapping out the Arduino for a Teensy, and making a real USB to MIDI interface.

A Black Box Mystery

One of the members of the SomethingAwful forum recently found a
black project box
on the street (as seen above), with no idea what the thing did. After (hopefully) making sure there were no explosives, [noapparentfunction] posted a picture online to see if someone could figure it out. According to them, this is what the chips are labelled as:
Center black IC: MICREL Y22758C; 0417
Long white DIP switch IC: CTS 206-12; T438
Small black microcontroller on right: 12C508A; 04/P1V6; 0437. Has a tiny “M-inside circle” logo.
From our experience, we recognized the PIC on the board, but without some more photos, it makes this mystery a little more interesting.
Right now their best guess is a garage door opener of some kind because of the 12 DIP switch part. Any HAD readers willing to investigate and weigh in? The game is afoot!
[thanks to Dave D. who sent this in]

I could find nothing more on that specific IC.But by searching for that description, I was able to find other ICs with similar function. Here’s a clip from such a datasheet:“The circuit is powered by an external coil placed in an electromagnetic field, and gets its master clock from the same field via one of the coil terminals. The other coil terminal is affected by the modulator. By turning on and off the modulation current, the chip will send back the 128 bits of information contained in a factory pre-programmed memory array.”The coil is no doubt that white cylinder.So basically, this appears to be a very fancy RFID tag.I can’t speculate on the function of the PIC. Perhaps it logs when the device is activated, or overrides the normal data stream to make it into a fully programmable RFID device.Whatever it is, it’s definitely NOT a garage door opener. :)",

If you look at the pic board, it has what appears to be an LM317 voltage regulator (i assume for dropping pack voltage for logic operations). There are 3 transistors, likely 2n3904/3906 or 2n2222. They are sourcing current to a relay(~150mA drive current). If you extract the garage door opener, the button should be shorted so that applying current to the battery terminals (where the pic board is connected) will send the signal. Without the code, you cannot see whether it is random trigger, or on a specific time of day trigger. SO it`s purpose is 1 of 2 things. 1. A guy that arrives home at the same time every day and wants it to open his garage door(unlikely). 2. A randomized (hince pic based) annoyance device to open his neighbor`s garage door at weird times (more likely).-The_Truth",

Elaborating on an item previously mentioned among last weekend’s
Cornell final projects
list, this time with video:
For their ECE final project, [Adam Papamarcos] and [Kerran Flanagan] implemented
a real-time video object tracking system centered around an ATmega644 8-bit microcontroller
. Their board ingests an NTSC video camera feed, samples frames at a coarse 39×60 pixel resolution (sufficient for simple games), processes the input to recognize objects and then drives a TV output using the OSD display chip from a video camera (this chip also recognizes the horizontal and vertical sync pulses from the input video signal, which the CPU uses to synchronize the digitizing step). Pretty amazing work all around.
Sometimes clever projects online are scant on information…but as this is their final grade, they’ve left no detail to speculation. Along with a great explanation of the system and its specific challenges, there’s complete source code, schematics, a parts list, the whole nine yards. Come on, guys! You’re making the rest of us look bad… Videos after the break…

We frequently receive inquiries from eager readers asking how they can best get started in electronics and computer projects. Countless great books have been written on these subjects, and of course now there’s our
answers.hackaday.com
site. But there’s a difference between being “book smart” and being “street smart.” What are the terms that you
really
need to know to get ahead in this field? We’ve collected a few of our favorites here.
Have any terms or definitions to add? Leave a note in the comments!

Whether you’re burning a new bootloader to an Arduino board, or doing away with a bootloader to flash Atmel chips directly, an in-system programmer (ISP) is an indispensable tool for working with AVR microcontrollers. If cost has held you back, it’s no longer an excuse:
FabISP
is a barebones USB-based AVR programmer that can be pieced together for about ten bucks.
FabISP was created by [David Mellis] as a product of MIT’s
Fab Lab
program, which provides schools with access to design and manufacturing tools based around a core set of
fabrication
capabilities
, so labs around the world can share results. But the FabISP design is simple enough that you don’t need a whole fab lab. It’s a small, single-sided board with no
drilling
required; the parts are all
surface-mounted
, but not so fine-pitched as to require
reflow
soldering. Easy!
There’s still the bootstrap problem, of course: you need an
AVR programmer
to get the firmware onto the FabISP. This would be an excellent group project for a
hackerspace
, club or school: if one person can provide the initial
programmer
to flash several boards, each member could
etch
and
assemble
their own, have it programmed, then take these out into the world to help create more.
We must repeat!
[Thanks Juan]

I started out with the USBtinyISP (on which the fabISP is based). I was only able to get it to work with avrgcc (not avr studio) which is pretty complicated for a novice to get up and running. After about a year both the driver chip and the micro in the programmer had to be replaced due to the lack of input protection. I also was never able to use it with win 7 64 bit and there appears to be no 64 bit support in sight. I ended up just buying Atmel’s programmer for about 40 bucks.If you are starting out you will have enough unknowns, try to limit it to your project and not your programmer too.

I started with avr programming through a parallel port without any usb or any specialty cables. I just ripped apart an old parallel printer cable and breadboarded everything. Worked the first time. The other advantage of the parallel port programmer is being able to program your first AVR without having someone else load a bootloader for you.http://sites.google.com/site/emrirc/avrstuffEnjoy,Ray MooreP.S. I am working on a tutorial for AVR programming from scratch and hope to have it up on the site sometime next month.",

If I want it in less than a month (average mail time from the US), I have to pay about 70$ for shipping. This means over 100$ for that programmer. On the other hand, I can walk to one of the electronics shops in my town (we have 5 or 6 of them) and buy all my parts for less than $10. An attiny is just 1.6 Euros (http://www.comet.srl.ro/shop/info.html?ID=8040) The passives are even less. I have lots of cables from MP3 players that are just laying around. The only thing that you can’t buy is the PCB, but it can be made for under $3 ($1 the etchant, $2 the PCB) and I can program the whole thing with an older device (one that requires a serial port).As long as this thing works with avrdude or ponyprog, it’s A-ok.So please stop trolling and do some research (like what’s a Parralel port and how can you use it)",

Your DJHI cartridge showed up in yesterday’s mail, BTW…I haven’t even had time to play with it yet, but it’s really nicely built.I appreciate all the discussion this has generated, both positive and negative, even Mr. Nibbler’s points. Once again my inner thrifty Scotsman got the best of me (hardly the first time that’s happened here) and I obsessed over the parts cost while the REAL value of the story is buried somewhere in the third paragraph: that this can be a great social (rather than solitary) electronics project…everybody’s got some of these parts in their junk pile. The software and hardware skill level are well-aligned…as a student is moving out of the Basic Stamp/Arduino bootloaders-and-jumper-wires stage, some of the skills they’ll next want to pick up include etching boards, surface-mount soldering, and flashing MCUs directly. The project offers all of the above without being too daunting in any one area, and unlike an “LED Christmas tree” the student ends up with a useful tool (albeit a rudimentary one) that will carry them just fine through the next few months of learning. Sure, if they’re serious they’ll eventually end up with a Dragon or something anyway, but I see this project as being more about the skills than the thing itself. Paint the fence. Wax on, wax off.",

I only suggest it because I once fried a laptop through an arduino USB cable while trying to rewire my piano.

[Tim] came across
a Kotaku story about a handicapped gamer
who’s starting an
Internet petition for button mapping features
in all games. First of all, watch this guy play Modern Warfare 2 with a stock control, he’s got some mad skills. We’d normally be looking for a hardware solution like this
PS3 Frankenstein controller
or a
controller emulator
to do the job. There’s also
the mix-and-match controller that Ben Heck sells
. But we’re inclined to agree that button mapping is a useful feature for everyone, especially if you’re in [Chuck Bittner’s] shoes. We still miss the console and macro capabilities of the original Quake… oh why didn’t that functionality make it into console gaming?

For some reason they brain-farted and the game is ridiculous.They fixed it in Flatout 2, but there is no local network play, and yes, you guessed it Live is now dead for original Xbox.If only to fix what the crazy devs do, this should be supported.I contend that it be supported at the BIOS, OS, or firmware level of the consoles.

They tend to be optional, so if you want to play a difficult game, set your game up for hard-core mode, and don’t make use of any optional assist modes. Baffles me how many people can’t grasp that. For those who still don’t like that concept, why not campaign for the removal of wheelchair ramps and level access to public buildings? Campaign for the removal of subtitles on DVDs? Etc. It’s daft not to see the bigger picture, and the fact that anyone can become disabled at any time in their life. If that does happen, do you just give up on wanting to play the games you previously loved? Or would you rather there were some accomodations in your options screen that can help to keep the game playable and fun?",

This is the way it should always be done.While we’re at it, I’d like to see more games like The Bouncer that let you pull up a graph of all your inputs and adjust your dead zones and sensitivity for the analog inputs.",

Using IPad SIM With An IPhone

[Aaron Nelson] tipped us off about a simple hack to
use an iPad SIM with an iPhone
. You won’t be able to use the iPhone as a phone, but the relatively cheap $29.99 for unlimited Internet was his goal. He used an old plastic gift card to cut out an adapter for the iPad’s micro SIM so that it will fit into the iPhone’s SIM cradle as seen above. From there he used a web service via the WiFi connection to enter “Broadband” as a custom APN.

Cat Door Unlocks Via Facial Recognition
|
Mike Szczys
|
[
"home hacks"
] |
[
"cat",
"door",
"image",
"recognition"
] |
Faced with critters trying to get in and a cat that loved to show them her latest kill, the folks at Quantum Picture came up with a system that
unlocks the cat door based on image recognition
. As you can see above, it uses a camera to capture the profile of anything approaching the cat door. That image is compared to stored positive identification sets, making up a feline positive identification protocol. Don’t think this is necessary? In the writeup there’s a couple of images showing the outline of a skunk. Sounds like this system is a necessity.
We wonder if this lucky cat also has
an Internet enabled cat feeder
?
[Thanks Stephen]

Electromechanical Game: Running With The Bulls

We’ve been watching the progress of this build for a while on
Flickr
. It looks like they’ve finally completed the electromechanical game,
Running with the bulls
. Based off of the event by the same name, you have to keep your guy from being trampled by the bulls as the charge. The entire bull structure is pulled forward on a timing chain with a stepper motor with each bulls individual side to side movement being servo driven. It actually looks kind of fun.

[Matthew Garten] built this
watch based on an Arduino
. The face is a small color display which allows you to choose to show time in digital, binary, or analog formats. In keeping with the recent trend here on Hackaday he has a glove-based add-on that has temperature sensors in the fingers; for Firefighters or those with nerve damage to their fingers (we’re thinking
Darkman
). For entertainment in any situation he’s included a trackball and the ability to play breakout or draw in 16-bit color. Details are scarce but apparently he’ll be sharing more soon. For now, watch the video after the break and think of ways to shrink this down into a nice package like
the Pong Watch
enjoys.

If you- or someone you care for has need of any Prosthetics, projects like this will cause that ugly sounding term “Biopunk” to become a concept of life altering hopes.We take for granted that all of our fleshly systems work as intended. And as we live longer, survive combat injuries or similar crippling traumatic damages etc- there’s a Very Good Chance of some people reading this post’s thread becoming in need of advanced Sensory Prosthetics.Take a moment to try envisioning your life being altered by something which leaves you needing technology for assistance.This glove project deserves a sincere appreciation from us all. For it’s value in advancing not only Hackerdom’s scope, It brings Sensory Prosthetics a bit closer to daily reality. So- before anyone decides to Flame/Nitpick in destructive comments- Revisit that moment of envisioning YOURSELF needing something of an assisting device. Perhaps then- you’d consider Mr Garten as deserving of honors for “Doing the Good Works”",

[Pikipirs] developed an app that lets you
connect a Wii remote to an Android phone
. After the break you can see it used with a Sega emulator. The button presses seem very responsive, making for a nice gaming addition if you care to carry around the Wiimote in addition to your phone. It certainly seems to work better than
the Wii remote + iPhone hacks
we’ve seen. Pick it up from the Android store or download the APK from the thread linked at the top. This is an alpha version so don’t be shocked if it’s buggy.

You must understand that I come from a free sharing of information background. I believe we stand on the shoulders of the giants before us (Isaac Newton)My father had a copy of BSD from Berkeley back in 1981(I was born in 79). I didn’t even know what the hell DOS was until I was about 8(games of course led me to it). For years I watched my father on BBS boards developing, debugging and being a cog in the wheel that helped shape computers into what they are and what they will become. My father didn’t get paid for what he did, it was just a hobby/passion. His “real” job was as a central office technician for the phone company. Point being that the brick layers did it out of love and fascination. Hell even Bill Gates had a love for the technology before he had a love for the money. That guy could code the hell out of some Basic back in the day. The founders of Google have an MO of “don’t be evil” Jobs though, he just happened to be in the right place at the right time. He sold phreak boxes out of his van that Waz and Cpt. Crunch developed as a startup way before Apple was up. He is a smooth salesman with a messiah complex, and he truly believes HE is changing the world. He used to fly a pirate flag outside of company headquarters to symbolize they were rebels and “anti-system.” When he was the one stealing he was being innovative and artistic. If he thinks someone is stealing from him it is blasphemy. Out of all the founders of the big three Jobs is the only one who was not a hacker, but he was very good at exploiting them.I suppose my point is that he and his company are becoming a menace to the progression of technology, and that is unacceptable. Instead of standing on the shoulders of giants he has his head up their ass looking to see where his precious patented technologies are. Look what he did to the poor bastard from engadget. That guy had a great scoop on a story and Jobs punishes him because one of his minions got drunk and left a IPhone prototype in a bar.Google I would imagine particularly scares him because they offer more to the world as a whole, and they offer it up for free. If they started charging you to use google how outraged would you be? If apple owned it you already would have been paying for it from day one, and you would have never known the difference.I am glad to hear you own outside the realm of Apple, if you haven’t already perhaps you should give Linux a try. If you already use a Mac it really isn’t that different (mainly because they are both offspring of Unix, one closed, one open)Unfortunately you mixed apples and androids the same day I was reading details about Apple suing HTC (specifically for their phones functionality while running android) and it set me off. I am not uncontrolled, I am just an asshole on occasion. I am human, so be it. I was actually sitting with my middle son 2yrs singing the abc’s with him before as I was typing. Hard to sing the abc’s if you are “pissy” None the less I will not “rage” (getting pissy sounds too gay) on you about Apple anymore because you appear to be a civilized person and I can respect that.",

[Losinggeneration] managed to get a
homebrew OpenGL application working on the Didj
. It’s nice to see the community driven work advance on this device but something else also caught our attention from
the forum post
. Another poster pointed out that [losinggeneration] has files in one of his directories called “glquake-didj” and “glquake-didj.dbg”. We hope that means a working version of Quake is on the way for
the hackable handheld
.
[Thanks JJ Dasher]

How is that quake port going btw?What strikes me most is that there is a large audience/demand for an open source hardware device but no supply for it. Some company should just create/sell some hardware running on linux and let the community do the rest. Bit like an arduino but in this case a handheld with touchscreen, wifi, io-port and a good lipo battery. The io-port to connect cheap servo’s and sensors for all robotics and household hacks.If they can get the hardware price low enough it should be an instance success. The gp2x gets really close to that idea, only with a price tag so close to the psp and no wifi, why bother?",

If manufacturing printed circuit boards has become too easy you should try your hand at producing transistors. [Jeri Ellsworth] put together a collection of
videos outlining the process
. These go way beyond the
IC fabrication
we saw from her in the past. It doesn’t take much, a 1000 degree oven with steam option, silicone wafers, and a variety of chemicals. We’ve embedded the instructional video as well as two demonstrations of her N-style FET after the break.

The real damage comes from HF’s ability to pass through skin, where it:* reacts with the calcium in nerves and bones, forming insoluble fluoride crystals which cause excruciating pain and interferes with healing* reacts with free calcium ions, causing hypocalcemia which shuts down the heart* causes general fluoride toxicityBy the time you feel anything, washing is usually insufficient and you’ll need medical treatment, consisting of topical and injectable calcium gluconate.

There is a reason BJT’s were used for so long – MOSFET’s have a lot of problems with surface defects and oxide impurities that can only be solved by cleaning up your process.Second, these are not the kinds of chemicals anyone should be using in their garage. HF is extremely dangerous – far more dangerous than HCl. Previous posts have touched on this already.Third, it would be far, far, far cheaper and more useful to buy commercial MOSFET’s. Obviously, that is not the purpose of the exercise, but the point still stands.Now I could definitely see homebrew point contact BJT’s being an interesting educational project, and possibly even useful for high power applications… maybe even a pnp or npn diffused junction BJT… but homebrew MOSFETS?

Nike + IPod As A Tracking Device

[Thomas] found a paper from 2006 that describes
using the Nike + iPod system as inexpensive tracking devices
. Yep, it’s old as dirt but we think it’s fascinating reading! [Scott Saponas] and his fellow authors take a hard look at the lack of security in the system in
a twelve-page PDF
. They cover several different ways to capture and track one of the $29 tags in someone’s shoe, including using the
Gumstix
reader above, or a slightly modified 3G iPod. If the sensors are not removed or manually switched off when not in use they can be picked up by any RF reader within range. Because the tags are cheap and available, one could be planted on an unsuspecting victim James-Bond-style. Maybe this is what prompted
Apple’s half-hearted attempt to restrict hacking
the devices to do things like
unlock doors
.
Of course if you don’t want to do the reading you could
download their video
presentation or
just stream it
.

Ghetto Repairs: Desoldering With A Candle

Yes, that picture you are seeing is serious. [Roland] needed a chip for a damaged piece of electronics. He was lucky enough to find one on an old board at a local shop. The problem was, he didn’t have the hot air gun to remove the chip the correct way. Instead, he simply
cooked the board over a candle
to melt the solder. Interestingly, after he cleaned the candle-cooked board, it looked like it survived without damage. The chip worked fine and fixed his problems. Sometimes,
we just don’t have the right tools
for the job.

Point And Shoot In A Classic Camera Body

If you think there’s a gun inside that camera you’ve been fooled. We just like the juxtaposition of the 1940’s era camera with the iconic sidearms. What you see is
a point-and-shoot cameras inside of the classic Leica II body
(this is actually a
Zorki 1 knockoff
). It is much like the
Canon AE-1
hack but this time there’s plenty of build details.
Digital camera makers try to get the smallest form factor possible and consequently the inside of those things is a nightmare of tiny parts and intricate connections.The Sony DSC-WX1 is no exception, and even the battery is disassembled to fit inside. See the final product and its features in the video after the break.

The mirror in those is usually not set at the focal plane, but just redirects the still not focused light onto a screen that is set at the correct location. You view that screen through, in good cameras, a pentaprism that corrects for the lens projecting the image upside down.If you have a bigger format, or something like a TLR, you might be able to fit the lcd in the camera in place of the focus screen. More details, and I will be glad to offer any insight.@vmspionagePut the CCD at the focal plane of the camera, where the film sits. Get it right to a very small tolerance, or you will lose near or infinity focus. Problem is, tiny digital cameras have a rather small CCD compared to the size of the film a Leica would shoot. You would need extra glass inbetween the lens and the sensor to adjust the light, and those are probably going to be custom ground. Or, scavenge a larger sensor from a DSLR. Or just get an adapter ring to mount M39 or Leica M lenses to the DSLR. Both would work.@alexNot just the goodwill. I got an isolette for a dollar from a tag sale. It’s not an every week find, maybe just a once a year ‘omg look at that’ event. But get friendly with the people at the thrift stores, and the people who go to yard sales every week, and tell them that if they find an old camera you would really like to take a look at it.@stunmonkeyI might be upset that someone trashed a real Jag. But, I see people making purses out of vinyl records I would love to add to my collection, and there are always stories of people with classic painting just sitting in the attic.

We’re being inundated with glove-based peripheral hacks. This is another final project from Cornell, keyboard out of the equation by
adding 8 piezo sensors to a pair of gloves
thereby shunning the
pinky
finger. We like this one because it’s easy to build and the midi interface implementation is well documented if you want to build your own.
As you can see after the break, this is easy to use with music software like Garage Band because it is a standard MIDI device. In addition, a MATLAB interface allows for custom mapping in case you want to change what each finger does.
We remember our first introduction to glove-based performances with
Tod Machover’s Bug Mudra
many years ago. We hope
the music input hacks
we’re seeing will lead to a whole new generation of music innovators.

Monitor UV Exposure With Your Sunglasses

Tired of those awful sunburns? [Nikko Knappe’s]
UV sensing glasses
will warn you before you become crisp and red as a lobster. The bump added to the bridge support hides a TSL230R light frequency sensor. The device automatically switches on when the arms are unfolded and starts tracking cumulative exposure. If it detects a rising UV level, or you are about to burn based on skin type, an LED inside one arm of the frames will flash to inform you.
This has some potential if you think
David Brin’s Earth
outlines how climate change is really going to play out. Either way it’s still fun and we give bonus points to [Nikko] for disguising the lilypad that controls this as a flowery hair-pin.

Building Air Variable Capacitors

In keeping with our opinion that radio operators were the original electronic hackers here’s a guide to
building your own transmitting air variable capacitors
. Using some roof flashing, Plexiglas, and various fasteners [
David Hammack] was able to make it work. It’s not a perfect solution but he has some ideas to make the next one better. Give this a try after you’re done
tweaking your crystals
and
building input devices
.

[Tanjent] send us a link to his
tutorial on the toner transfer process
for fabricating circuit boards. We’ve seen a lot of these in the past, but we liked how his is straight to the point while also sharing several tips and options along the way. Notably, he ”tints” the copper clad before trying to adhere the toner to it by swabbing on a bit of etchant. His reasoning for this is that the toner has more trouble sticking to the shiny copper. Just a bit of etchant will pit the surface and let the toner stick better.
He’s still using paper as a medium and not
printing toner powder directly to the copper clad
. His paper of choice is HP Brochure Paper while we use glossy pages from the union newspaper. But like us, he does use copper chloride as an etchant, which you can
learn to make yourself
. We’re still looking for a definitive solution for disposing of this chemical. We’ve been using the same batch for years and recently it’s turned cloudy with impurities. If you’ve got disposal tips let’s hear them in the comments section.

To make it safe for disposal, you can add sodium carbonate (washing soda) or sodium hydroxide to it to neutralize it, until the pH value goes up to between 7.0 and 8.0, testing it with indicator paper. Copper will be deposited as a sludge. Allow the sludge to settle, pour off the liquid, further dilute it with water and then it can be poured down the drain. Collect the sludge in plastic bags and dispose of it as required by your local waste authority.”",

After a while, the H2O2 has all decomposed, but then you have CuCl2 floating around andCuCl2 + Cu –> 2CuClThe chloride ions can be replenished from the HCl, and dissolved oxygen.4CuCl + 4HCl + O2 –> 4CuCl2 + 2H2OThis is why the must be periodically refreshed by adding more H2O2, or by bubbling air through it (preferably outside and WELL AWAY FROM ANYTHING MADE OF STEEL). This reaction also consumes the HCl, so it must also be topped up (but less often).Of course, the actual mechanics of all this are happening with ions dissociated in solution (except for the metallic copper), so the above is somewhat simplified.Running on the assumption that the etchant looses potency because the solvated copper concentration reaches equilibrium, plating out the copper as Enviro suggests might restore some potency, but you couldn’t use aluminum. Perhaps you could electroplate it out with a carbon anode, but I doubt that the pittance of copper you would extract would be worth the immense hassle of an electrochemical cell. Not to mention, it would probably also belch Cl2.Probably best just to flush it down the sewer with a sodium carbonate chaser.",

I have lots of those lying around from work (big sheets) so I decided to give them a shot one day.The idea is to print on the glossy side, do the heat transfer method of your choice, then simply peel the backing paper away from the fused toner. The latter part is what makes this paper awesome, you effortlessly remove the paper as if you were peeling a sticker.The biggest hurdle is actually getting the toner to stick on the paper sufficiently long enough. The glossy side is so smooth that the toner starts to flake off from trivial movements and flexing. Sometimes the printer itself rubs off the toner as it spits out the paper.You need to use fine abrasive sponge to roughen up the glossy surface, just rough enough for the toner to stick. Can be a hit and miss at times; obviously you need to use trial and error to find the ideal roughness. The end result should look somewhat matte, as opposed to very glossy. Even in this state the toner is VERY sensitive to mechanical stress, so you need to handle with care and definitely not touch the toner – once you do it’s all over. The beauty is that you can reuse the paper if you screw up – just use cotton wool to wipe of the toner and start again.The second tricky bit is placing the blank PCB on the print in such way that it does not shift the or perturb the toner underneath. That means no sliding, twisting, rotating, shearing. Must fall flat. Once it’s down it stays down. Use a tape that is sticky enough to keep the glossy paper fixed to the PCB. I use a hot clothing iron as a heat source. I just put it on top of the PCB and let it sit under its own weight for a while. NO movement.Once done, peel the paper off and you have a fairly decent transfer. This seems to work well for non-SMD work, about 0.7 to 1mm wide tracks. Anything smaller is not recommended.",

Hand Made Manipulator Arm

We’re pretty used to seeing CAD used in the design process for most things. It’s a bit of a shocker to come across a project this involve, and this well executed, that didn’t use CAD.
[Anton] spent 100 hours
building this manipulator arm by hand
. He made the parts by drawing them on styrene and cutting them out with scissors. He has started building version two with AutoCAD but from what we’ve seen in the video after the break, improvements on the original design will be minor. The speed and fluidity of the servos with added magnetic encoders makes for a graceful robotic dance; we’d love to be its
chess partner

[Rich] shares with us his build of a
Peltier cooler based cloud chamber
. This nifty little tool allows him to see the paths that radioactive particles take through alcohol vapor. The system he has come up with is fairly cheap at roughly $100. He’s using Peltier coolers from computers and a cheap ATX power supply. You can see a more detailed
instructable
here.

Have you never wondered exactly why it is that night vision goggles can see people in infrared? It’s because the energy we perceive as heat has to go somewhere (in other words, eventually you get cold) and that heat radiates away from us in substantial amounts.Some kinds of high energy radiation are bad for humans. This doesn’t mean that ALL radiation harms people. Some things radiate photons, some radiate electrons, and some radiate protons and neutrons.Alpha particles (proton+neutron bundles) generally cannot hurt you (the primary form of radiation coming from the sources visualized in this post). In fact, they’re able to be stopped by a piece of paper. Your skin protects your body rather well from these particles, though it would be a bad idea (and potentially life threatening) if you were to EAT a source of alpha radiation.Beta particles (electrons) usually require a block of wood to stop them. They can penetrate your body and do harm to your tissue – usually in the form of burns, but also are capable of damaging your DNA.Gamma radiation is usually the highest energy radiation of all of these and the type that can pose the greatest threat to your health. Not all radioactive materials are gamma emitters and not all gamma emitters are dangerous.If some of you are going to freak out any time anyone mentions “radiation” then stop using your microwave (electron radiator), don’t turn on any lights (photon radiator), and throw out your smoke detectors (they’re nuclear – alpha and the rare gamma ray radiator).It’s a pretty safe bet that the americium sample depicted in the picture above came from a smoke detector.",

[Erik] and [Jonathan Bergqvist] built this
shoulder mount for a Canon 7D camera
. It’s made from wood and it hooks over the top of the photographer’s shoulder with a handle for each hand. The left handle also controls the focus, using a similar method to the
hardware store follow focus
we looked at in January. Like it or not, you’ll love watching a master woodworker build this starting with un-milled logs. It’s all about having and knowing how to use the right tools.
[Thanks Juan]

Building Removable Epoxy Mounting Brackets
|

"bracket",
"epoxy",
"kodak",
"Sugru",
"zi8"
] |
[Jykazu] wanted to use an external lens with his Kodak Zi8 but he didn’t want to alter the camera or glue something onto it. His solution was to
build a bracket out of epoxy dough
. He first covers the camera in scotch tape to protect the finish, then he kneads the dough to mix the two parts together, using it to form the bracket that you can see above. After curing, the bracket barely sticks to the smooth tape and can be gently removed. A lens cap with a hole drilled in it is glued to this bracket and works like a charm for connecting the lens. Check out his manufacturing method in the videos after the break.
This is a great method for many applications. Last year
we saw a product called Sugru
which seems to be made for this type of thing but [Jykazu’s] epoxy method is just as impressive.

This is a covert type project, where the camera is hidden and so is the light that helps it see, and it needs to be portable. I would like to use this camera as the input to my Kodak Zi8 instead of the default one. The Kodak already has an audio input jack. Would it be possible to remove the built in camera/sensor, and wire in an input jack for video? Then, I could connect my external camera, via a nice long cord, or anything really with a video feed.Pocket DVRs are crazy expensive. I can’t find anything below $300 usd.",

PC Side IM-ME Hacks

"im-me",
"keyboard",
"prompt",
"winamp"

[Paul Klemstine] is working on some PC-side
software hacks for the IM-ME
. We’ve seen a lot of hardware hacks for this device, such as
controlling the display
,
firmware flashing
, and using it as
a spectrum analyzer
, but if you don’t want to alter the device right away you can try [Paul’s] collection of hacks. Working with the code developed by [Ben Ryves] there is support for using the IM-ME as a command prompt, to control Win amp, and as a wireless keyboard. Crack out your C# skills and develop the next feature for this inexpensive device.

Build Your Own Wikipedia Reader

"arm cortex",

One part inexpensive uC, one part touch-screen, one part Internet knowledge-base all come together to make up
this Wikipedia reader
. It functions in a very similar way to
commercial versions
by parsing XML dumps from the popular website to an SD card for use on the device. This is not limited to Wikipedia, but could just as easily be an e-reader. [Rossum] developed the package using an NXP ARM Cortex M0 model LCP1114 microcontroller. They cost just a couple of bucks but pack a 50 MHz punch with 32 KB of program memory and 8 KB of SRAM. If the
nanotouch
and the
A
VR iPhone concept
didn’t convince you that [Rossum] knows what he’s doing, the video after the break of this newest creation will seal the deal.

[John Park] is documenting his build of a Nerf Sentry gun. So far, he’s
rigged the trigger
and set up the
motorized base
. He’s documenting the process in fantastic detail with great photos along the way. If you want to see what it will be like when it is finished, check out these other
Nerf sentry guns
that we’ve
featured in the past

Digikey Sort By Price Script

Does anyone else find it a little ironic the electronic retailer SparkFun is
advocating scripts to help Digikey
have a Sort By Price function? Regardless, to
reiterate
now
Firefox
(and we hear
Google Chrome
too) users with the
Greasemonkey
plugin can sort
Digikey
items. Personally, some of us here are just
Mouser
fans at heart.

There’s no script to do the work for you (yet), but at least my method uses Digikey’s functions and works instantly across multiple pages, instead of having to download every single page and sort the results.The key is inside the source for a results page. For the columns that already can be sorted, you can see a ColumnSort value. Using trial and error, I determined that the correct ColumnSort value for ascending price sort is 1000011. You can construct a request to Digikey’s server and end up with something like this:http://search.digikey.com/scripts/DkSearch/dksus.dll?Selection&Cat=2556317&k=74hc04&ColumnSort=1000011&stock=1That URL returns all the in-stock products matching the keyword “74hc04”, sorted ascending by price. You can replace “74hc04” with any desired keyword. I imagine a script to implement this could replace the value of ColumnSort with 1000011 in any search request sent to DigiKey.”-macetechMuch more useful! Now somebody needs to hack that into a greasemonkey script and we’re good to go.",

[Mitchel Humpherys] and his fellow developers didn’t just develop a maze-solving algorithm, they also
built a ping-pong ball maze platform that is computer controlled
. Using a webcam the computer picks up the high-contrast maze by peering down from above, calculates the solution, and moves the ping-pong ball to the goal using two different tilt servos controlled by an 8051 microcontroller. But wait, there’s more! Why have the computer solve it when you can
make a game out of a maze
? Once the PC was thrown into the mix it was pretty easy to add Wii remote and Wii balance board control too. See these alternative inputs in action after the break.

PS3 Patch Allows Linux Installation
|

"geohot",
"linux",
"otheros",
"sony"
] |
[Geohot] came up with
a patch that allows OtherOS on 3.21 PS3 firmware
. You’ll remember that
Sony released version 3.21 specifically to prohibit OtherOS
which allows the installation of Linux for which
they were subsequently sued
. Well, now their “fix” doesn’t work on people willing to flash patched firmware which means they’re only punishing those who play by the rules. Ugh.
Wondering why this is a big deal? Check out this article on
the effect Sony’s move has on PS3 clusters used for supercomputing
; something we hadn’t even thought of initially.
It turns out that this patch was released more than a month ago. Sorry for the late coverage but it’s new to us. You can see the obligatory proof video of the patched OtherOS after the break.

I’m confused.As for people running linux clusters of ps3s, I don’t understand why they were required to get the patch in the first place, if all you’re using it for is linux, and you have your cluster all setup and perfect and stable, why the heck would you download automatic updates and change it? At every corp I’ve worked out that’s the kind of thing that was scheduled and techs did manually to the servers, and if things got fubar’d, they would roll them back. I’m betting the ps3 doesn’t have rollback, but also, it’s not really server hardware anyway, it baffels me that people thought using these in clusters like that would be a good idea.",

His RAM glitch for PS3 to this day has literally not executed a single instruction. All his claims are BS that ran out of merit which is why all his sites are on lock down now..",

[Bunnyboy] pulled off some wizardry with this
custom NES cartridge
. Inside is the mainboard for a Game Boy as well as his own custom PCB with the comb connector needed to interface with an original Nintendo Entertainment System. In his own words it’s “a Super Game Boy without the Super”. The expansion port to for the handheld is still accessible for some head-to-head Tetris or use with the obscure Game Boy printer.
[Thanks Maxym]

With the NES though unless you can get hold of a PPU that exports RGB signals outside the chip and jam it into a Famicom you are out of luck. Even with such a PPU the colours aren’t 100% correct.I started building (in VHDL) a PPU clone that could replace the original PPU and give DVI/VGA out… it’s one of those jobs that you need a good logic analyser for and I don’t have one.",

"content": "Thanks for picking it up! Here are a few more tech details for those who understand :)The CPLD (XC95288) is the center of the board. It enables the boot ROM, which sets up the NES display and sends the NES controllers. The CPLD latches the controller buttons and sends them to the GB when requested.The CPLD also receives the GB LCD signals which are pretty basic vert/clock/data. Shift registers assemble the serial pixel bits into bytes, and then using counters writes it to the CHR RAM address of the correct spot on the NES screen. The original GB uses 2 bits per pixel for a 4 grayscale display. When only the NES background layer is used there isn’t any color translation because it is also 2bpp. By using a fast (15nS) SRAM I could easily pack in two GB writes between every NES read.The CPLD also does triple frame buffering in hardware so the slightly different frame rates don’t cause graphics issues. In my first one there was occasional tearing while scrolling without it. NES is drawing one frame, GB is writing another frame, and the third is either filled (GB finished writing) or empty (NES finished displaying).The audio choices is just a limit of the NES. Without a simple resistor addition there is no audio input from the cart to the NES. There was on the Famicom but it was removed for some unknown reason. Not sure how the SGB handles audio, but the SNES has massive cart bandwidth compared to the NES because of DMA.",

Open3DP Looks At 3D Printing In Common Materials
|
Mike Szczys

[
"Misc Hacks"

[
"3d printing",
"ceramic",
"glass",
"kiln",
"sugar"
] |
[Buddy Smith] sent us
a link to Open3DP
which he calls “REAL 3d printing hacks”. Open3DP showcases the projects of the Solheim Rapid Prototyping Laboratory at the University of Washington. They’re working on 3D printing in materials that can be commonly acquired and to that end
they publish recipes for powder printing
in materials such as sugar, ceramic, and glass. Take a look through their archives. We found the post on
microwave kilns
interesting, as well as
the writeup about Shapeways glass printing
which is seen above. We’ve also embedded a short video on Open3DP’s work after the break.
Update:
[
Mark Ganter
] dropped us a line to clarify that Open3DP was the first to develop printable glass about a year ago, called Vitraglyphic. They’ll also be presenting papers at
Rapid2010
and announcing a new printable material.

Hack Your Crystal’s Frequency

[Drone] tipped us off about [Joachim]’s efforts to
alter a crystal’s frequency
. Through a process called penning, a crystal’s resonant frequency is lowered by painting the crystal with an indelible ink marker. Our curiosity piqued, we went off and found
more information about penning crystals
. It turns out this technique has been around for nearly as long as there have been amateur radio operators. Outside of your local oscillator, and
radio jammer
, how might you best use a hacked crystal?

"content": "> ignorant question…. Can’t you just buy another> crystal with the required frequency??? or may> alter it with a variable cap???Good question:1. Not every frequency value is available. Amateur frequencies are available from suppliers, but not every frequency, just the most common. And, you rarely find Amateur frequencies in ‘industrial’ crystals (like the usual 4Mhz, 16Mhz, etc. that you might run your Arduino or PIC from).2. You can custom order the frequency you want. There are number of manufacturers who’ll do this for you. But it’ll cost maybe US$15 to US$35 PER custom valued crystal.3. You can ‘swing’ a crystal with a variable capacitor, or a trim-cap, just not by much.Mike YKM5ZDallas, Texas",

With a consequent reality of those tweaks being inherently at major risk of instability or other failure modes. Same goes for external tweaks like resonance shifting by circuit element value variances. The basic operating principles of some technologies are to risk an almost pun- rock bound. There are some exceptions to solving the problem of not having a crystal on the desired exact frequency. PLL synths being the present day most commmon method. But there’s an intermediate technology trick that seems forgotten. Direct Multiplication/Division with up/down mixing can produce desired frequencies from stock crystals at “good enough” stability to cost ratios.Look at some CB radio circuits pre-PLL for details. and IIRC some Aviation radio systems made use of similar methods. The prime difference between switched crystal/multiplier circuits and a VFO is that stability to cost ratio. You “can” build TXCO oven style VFO etc devices and yes, a stable thermal box inherently does improve accuracy of all oscillators.After all the harsh realities are weighed though? The elegance of hacking a crystal by direct mechanical or chemical means lives in those applications where it really is “good enough” of a hack.",

"content": "basic rule of thumb for this method.Thicker – slowerThinner – fasterMany a crystal radio set was moved in frequency by either sanding down (comet works well) or building up (pencil lead or solder work well).Don’t plan on moving it very far though.@oren: Harmonic modes are good for larger shifts, but are always going to be a multiple of the primary resonance. you can get the resonance out of the xtal itself or pick it out of an overdriven amplifier. W1GHZ uses this technique in his 902mhz,1.2ghz,2.3ghz and 3.4Ghz transverters to get the local oscillator frequency for example.As to the ‘get a new xtal’ suggestion, custom frequency crystals can be ordered but often take time to get and are often Not Cheap. iirc, the xtal for my 50mhz beacon (which needed to be @ 50,076,500hz +/- a few hz) was about $30 and took 4 weeks to get. Putting it in a xtal oven keeps it within a few hz, less xtal aging.Lest you think those last few digits are insignificant, when you start multiplying to get up into ghz range for microwave radios, it adds up. Multiply 50,076,500 by 50. Do the same for 50,076,550. The difference is 2.5Mhz. More than a whole FM radio band channel separation. Makes it hard to hear the other guy.",

I could see myself doing it to bring an old rock bound station to life operating, exclusively on a net frequency. In tat case the process is made easier in that many of the older stuff used crystal sockets for crystal holders that where made to come apart for easy access to the crystal. Otherwise I’d spend the money to have a custom crystal prepared, because it wouldn’t be something I’d need to do often, or rarely. Other than applications where the crystals can be mass produced inexpensively, crystal control is reserve for applications where accuracy, and stability is required over a wide range of changing operating conditions. IMO in such application money spent for a custom crystal, is money well spent, and may be the responsible thing to do, to do all I can to prevent interference to others.",

[Ben] bought a remote starter for his car but needed a way to make sure the manual transmission was in neutral when starting. He built this
infrared sensor frame to detect the position of the stick
. It uses four beam paths which will tell him the exact gear or neutral position of the shifter. For this project he just needs to detect neutral but exact gearing is apparently necessary information for his next hacking project. We initially were worried about sunlight interfering with the sensor readings but he’s building this to go under the collar that is used to cover up the mechanical joint at the base of the stick.

"content": "Hi guys, thanks for all the feedback on the project. I will try and respond as much as possible.Most people I know with manual cars have older vehicles and there are no factory neutral safety switch. This device just tricks the car to thinking the clutch is pushed in when autostarted.A manual car should normally be parked in gear. That being said, in winter it is so freaking cold I would rather leave the car in neutral and use the autostart. This makes sure I didn’t forget to leave the car in neutral. Plus if a shop is working on the car or a friend is borrowing it no worries!A few people have also mentioned that really only 1st and 2nd are a threat, I felt the autostart repeatedly trying to start the car against the parking brake would be best avoided in all cases!@Jorge: Thanks for the info, I will look into that.@pottymouth: You do bring up a valid safety concern, and safety was a priority in this design.1. The detectors only have a <12 (maybe even 6) Deg viewing angle and they are pointed under the dash and at a door. I was unable to get a false start even on a sunny day with the car as open as possible.2. The sensors must read high signals to start, open sensor does nothing. In my PIC controlled version (coming soon) the LEDs with be pulsed and the PIC will verify the transmitted and detected pulses match. This is meant to be a very basic design for people who don't want to go nuts with triple fail safes and micro-controllers.3. Most people now just short out the clutch sensor and hope they don't forget to leave the car in gear. I feel this is 100% better than that. (I know people who have had accidents because of this)Keep the comments coming!",

This solution would not be safe as a disconnect or emitter failure would act like a positive reading. Requiring two positive horizontal reading allows me to safely assume the stick is in the neutral position.The reason I have two vertical sensors in addition to two horizontal ones is it allows my PIC (on a new project) to not only determine if the car is in neutral, but which gear it is in. This will then be displayed on the instrument cluster as I shift though gears.So long story short, for this particular project you are correct, only the horizontal sensors are needed.",

We love a beautiful and successful
N64 portable mod
, (In case that fact wasn’t
already obvious
). And today we would like to add [cndowning’s] Nimbus N64 to our list of favorites.
The base is made from vacuum formed plastic while the buttons come from a modified superpad and the screen is a Zenith 5inch. We couldn’t find word on battery life or weight, but for those that like a hunt, or have other questions, the
build logs
are available
. Follow the jump for a video of the Nimbus in action.
[Thanks Fernando, and GaryC for our silly typo]

XKCD Takes A Swipe At The Arduino
|

"arduino",
"categories",
"xkcd"
] |
This
XKCD comic
takes a playful swipe and almost everything, including the Arduino. We’ve heard people claim that we have some sort of favoritism toward Arduino, and we don’t. People just submit a LOT of projects with them. But there is one point that we’ve seen a few times that should be addressed. In our categories we have an “Arduino hacks” section. That will not be going away, again, because we get so many submitted. However, shouldn’t we also add some categories for other stuff? Should there be a “pic hacks” category, or maybe just “microcontroller hacks” category?
Let’s not making this an Arduino bashing thread. Instead, give us some good ideas on other categories you would like to see for sorting.

I don’t think more static sections are helpful, if you open up a PIC section, the ARM people might shout and the 80C51 oldtimers, and the Japanese Motorola-people, and if the have enough power the TI MSP430 will try to argue as well…..Expand tagging and make a more flexible selection possible",

Making Magnetite Nanocrystals

Unlike many chemistry projects we post here,
making magnetite nanocrystals
doesn’t require anything that can’t be found in a local grocery store. All that is required is oil, vinegar, crystal drain opener, and rust. We don’t recognize the specific brand of drain cleaner that they are using, but we’re sure that you could find one with the same ingredients. Magnetite nanocrystals are used to remove arsenic from water. If you are in the USA or most of Europe, that’s not a big concern, but it can’t hurt can it?

Looking for an interesting project to do using an Atmel Mega644?
Students at Cornell University
have got you covered. They were required to choose, design, and build a project using the microcontroller; and this year is quite promising with
video object tracking
, the always popular
theremins
,
helicopters
,
Potentiostats
, even
Pavlovian conditioned mosquitoes
, and more.
Of course all the previous years are included as well, making over 350 projects total.
[Thanks Bruce Land]

5×2 Patch Board
|

"breakout",
"idc",
"pin header",
"pin socket"
] |
Sometimes we want to sit on the back porch, crack a beer, and do some prototyping. Other times we’d like to do the same but on the couch in the livingroom. To that end we added a 5×2 pin to 10×1 pin patch board to our solderless breadboard.
The 5×2 pin form factor is pretty common, used as an AVR programming header, on development boards like the Dragon Rider 500 and the STK 500, and in small prototyping devices like the Bus Pirate. We like the freedom of using IDC cables as interconnects and that’s where this board comes in. Now we can patch into the IDC cables yet still quickly disconnect them when moving to a different prototyping location. Check out the PCB artwork and this handy device in use after the break.
Above is an image of the
DS3232 breakout board
we made a while back.
We have probe cables
that we could use to connect directly to the pins on the breakout board but as you can see, we need a smoothing capacitor and three pullup resistors in this circuit so we’re using a breadboard. In the past we’ve connected jumper wires directly to one end of an IDC cable but it’s difficult to ensure you’re made the proper connection and the wires frequently come loose. With our new breakout board attached to the breadboard, solid connects can be made to the 10×1 pin sockets while preserving portability with the 5×2 pin header.
If you want to make you’re own, the PCB artwork is below. We used 6-32 machine screws, nylon spacers, washers, lock washers, and nuts to firmly affix the PCB to holes we drilled in the base of the breadboard. Good luck and let us know how you like this addition.

Reuse That PDA As A WRT Terminal

[Michu] used his old
Palm IIIc to make a serial interface
for his OpenWRT router. It’s a matter of cracking open both the router and the Palm device, then connecting the TTL lines from the router to the MAX 3386e level converter chip inside the Palm. From there, Pocketterm can connect to the router’s serial terminal.
A lot of us have old electronics lying around
that work perfectly well. It’s nice to find hacks that make them useful again.
[Thanks Isama]

This is an interesting take on a music box. [Blair Neal] is using an overhead projector with a roll of transparency to make
a synthesized music box
. A camera watches the projected image and feeds data to Max/MSP to produce the sounds. Customization merely requires creative image analysis. In this case, different colored pens or different tracks can be assigned to a sound with the speed of the track based on how fast you wind the transparency spool.

More Glove-based Interfaces

You may remember seeing
the golf glove air guitar hack
last month. Here’s two more uses for gloves with sensors on them.
On the left is a glove interface with flex sensors on each digit as well as an accelerometer. The VEX module reads the sensors to
detect sign language as a command set
. A shake of the hand is picked up by an accelerometer to delineate between different command sets. See it controlling a little robot after the break. This comes from [Amnon Demri] who was also involved in
the EMG prosthesis
.
Straight out of Cornell we have
the SudoGlove
, seen on the right. [Jeremy Blum] and his fellow engineering students bring together a mess of different sensors, sourcing an Arduino and a XBee module to control a small RC car with added lights and a siren. There’s embedded video after the break. You may want to jump past the music video for the description that starts at about 3:52.

FPS Controller Hacks Getting Easier

"zapper"
] |
It used to be a major production to build a gun-form-factor FPS controller but commercial tech has adopted many of those traditional hacks over the years. Now, [Nirav Patel] is
playing Cube with a Wii zapper and a SpacePoint
. All that was really required to make this happen is a patch to
Cube
, the open source FPS.
[Nirav] has plans to make this controller wireless using a BeagleBoard. We’re wondering if there’s support for using the Wii motion plus? We’ve seen
motion plus Arduino connectivity
, as well as
direct PC connectivity
. The Wii remote
already connects to Linux
, what about pulling that data down from the Bluetooth connection? If you’ve done this,
send us a tip
about it.

Then you dont need to have it on your gun. use the gun for aiming but be able to see everything around you…. just a thought ;)",

TOBY: Reel Mower Bot evolved

"motor",
"mower",

"reel"
] |
[Grayson Sigler] rolled out
a new version of his robotic mower
which he calls TOBY.
The previous design
added motors to a reel mower but he had trouble with traction. The new design is more of a utility robot platform that is used to tow the reel motor behind it. With better wheels, a much more stable base, and plenty of power this is a significant improvement.
His parts order came since we last checked in and he now has RC fully implemented. Check out the video after the break.

[MODDEDbyBACTERIA] has posted this instructible on
how to make a bluetooth SNES controller
. The bulk of the parts come from a bluetooth MSI game pad, so this isn’t a scratch build, but the amount of modifications required definitely qualify this as a hack. We were quite surprised that he managed to stuff all of that back into the case as well as he did. Great job.

Twilio Adds Touch Tone Telephone Control For Arduino
|

[
"Arduino Hacks"
] |
[
"arduino",
"phone",
"touch tone",
"twilio"
] |
An Arduino with an Ethernet shield, nothing new right? Not quite, [Chris] is showing us
how to use Twilio to control an Arduino
via a touch tone telephone. We saw
Twilio used before in a cellphone
video game but this time around an audio menu system comes into play. You can make your own menus whose options will be read by
the WOPR
(see the demo after the break) when you call the Twilio number. This application just turns an LED on and off but once you’ve got access to the Arduino the sky’s the limit. Most immediately this is an easy implementation for all those
cellphone door lock systems
we’ve seen. We also envision some classic home automation such as feed the cats or turn on the lights.

Multiple Material 3D Printing

[youtube=http://www.youtube.com/watch?v=D4Yq3glEyec]
It’s no surprise that we’re wild about 3D printing,
especially [Devlin]
. Now we’re absolutely out of our minds for this multi-material polyjet machine that is
featured in the video
above. Before we go any further it’s worth mentioning that this post is not advertising, we just think this machine is unbelievable.
It is capable of printing 600 dpi in 3D using multiple materials at the same. Two types of rigid material, one like ABS and the other like polypropylene, as well as seven levels of a soft material all exist on the same print head. They can be deposited along with a support material at the same time. In the video you can see enclosures that come out of the printer with rubber-like padding already mounted in the hard plastic shell. They even show a bicycle chain that is fully assembled after printing. Cost for these machines? We don’t want to know, it’s just fun to dream about having unrestricted access to one.

"content": "“I think it’s because the materials cost too much. AFAIK all two part polymers components degrade over time, which isn’t cool for the home/hobbiest market.”Wrong. These are one part materials. Technically, the inks have acrylic/epoxy/urethane/polyester chemistry (monomers and oligomets) plus multiple photoinitiators, stabilizers, surfactants, etc. Nothing TOO fancy but their inks contain quite a number of components, components you can’t just buy one at a time in small amounts. We are talking about 55 gallon drum feedstocks.I own multiple Objet printers and the materials are crazy expensive. $500 – $800 for a single cartridge, which is only good for 2 – 3 large models and by large, I mean under a cubic foot. More like 8x8x8.The materials don’t degrade over time once printed although they do have a shelf life due to the reactive nature of the materials. However, there are certain things you can do to improve that.Also, the printheads are expensive. The construction is a bit robust as they are industrial printheads that are designed to run at 65 – 75 degrees C. This machine has 8 printheads (as do most of their machines except the Alaris which has 1 and Eden 250 which has 4) and each printhead costs $1100 or so and is only good for a few thousand hours.However, the quality is fantastic. EnvisionTEC has better quality potential but they can’t print support material – so they have to build scaffolds out of the model material to support the material. Since the scaffolds are made out of the same material, you have to manually remove (with a knife) those and it leaves marks where you do that. On large projects, that can take a LONG TIME to clean the model up enough and on some geometries, it isn’t even possible.All that said, I wish the DIY market were to go after polyjet technology over makerbots. By their very design, makerbots are limited. You can’t make the “glue gun” printhead much smaller and you can’t fill in “pixels” with a round nozzle. Delamination is an issue and ultimately, quality is not likely to get anywhere close to polyjet anytime soon, if ever. But they DO make what can be called “parts”. Kind of. No offense intended.If you were able to marry room temperature UV inks (that Objet doesn’t have – all of their inks are too “thick” to be able to be printed at room temperature) with off the shelf printheads (or a gang of printheads) then you would be on to something huge. Because then you could use LED UV lights, cheap printheads and presto – ultra cheap, ultra high quality printer with very cheap consumable prices. Trust me, those inks have a HUGE markup. If you were able to buy them at cost, I imagine, actually I take that back, I know that pound for pound, they would be on par with the ABS plastic used in most makerbots.“What the RepRap lacks in surface finish it makes up for by being cheap. A reprap (or makerbot) costs many orders of magnitude less than any commercial machine to set up, and the objects it produces cost just 2.2 cents per cubic centimeter (less if plastic is bought in bulk). Try to find a commercial machine that can even come close to that.”I can’t go too far into the details, but if you know what you are doing, you can create inks for polyjet technology that rival those prices.“I wonder if I could find a UV setting polymer that would pass through the standard thermal heads of my inkjet printer at home. If I could, then this could be truely home-made.”You will most likely not be able to. Traditional piezo inkjet heads jet at room temperature. Most polyjet ink would never flow at all at room temperature, you would have to thin it out with monomers, which lower the quality of the part – usually so much so that the part you printed would have no mechanical properties at all. And off the shelf printheads jet far too low of a quantity per jet. You need ideally around 60 picoliters per drop. 30 would work. Most inkjet heads might manage 1. You would also need to print more than you need and then scrape a small amount off because you can’t deposit EXACTLY what you need.You would also need 1 – 2 250 watt UV bulbs and requisite power supplies along with some algorithms to compensate for blocked jets, an accurate to 16 micron Z axis, etc. Not that it can’t be done but the ink and the ink delivery system would prove to be a rather large challenge.I spent 2 years and six figures developing a custom formulated room temperature polyjet ink that has multiple patents pending. And I would very much like to see DIY polyjet printing not only happen but become the next big thing. Honestly, there is no compelling reason why this can’t happen. All it takes is inks that can be run through inexpensive inkjet heads. And I know for a fact that something like that is possible in a machine that could be assembled for under $1000 that costs the same as a makerbot to actually run.",

"content": "Because you have to hold the material you are curing and prevent it from moving so when it does the mechanical recoating cycle at the end of every exposure (to build the resin up), it doesn’t move the model you are trying to make. If it moved even a micron with each pass, it would very quickly ruin the model. So you have to anchor it. Also any overhangs past a certain amount need to also be anchored. At MINIMUM, you need to anchor the model’s base (whatever you you designate as the base because you tell it what face the base is) to the build tray. Depending on the overhang angle, you may be able to get away with just that one support “material” geometry using EnvisionTEC’s technology.EnvisionTEC is really more akin to SLA then SLS. They just use MEMS DLP and a projector bulb instead of a UV laser. SLS in plastic powder does not generally need support material but in metal it does (because the density of sintered metal is far heavier than the density of loose metal powder).",

Some inkjet designs seem to be able to do drop sizes from 2 to 50 pL. A less viscous material with a lower boiling point will also increase volume.Arrays of print heads: Sure – I guess you could have a 4×4 array of print heads to print at 16x speed – aligning them would be a pain.Material Cost: non-issue, most of the ingredients are produced by the barrel.Accurate XYZ positioning: Well X and Y are done already in a home inkjet. Z only has to move one direction, slowly, so not too hard. One could begin with only X and Z, and print tiny models no bigger than the length of the print head.PolyJetter: Feel free to contact me with the contact form on my website.",

You can use water (which is a great solvent) but you have some of the same problems – and water has to be heated up a lot to evaporate. But then you add in the miscibility problem. UV resins tend to not be water soluble. Only a few PEG based hydrogels, modified BPA epoxies and the like are actually what one could consider water soluble. And very few are 100% soluble.Also, keep in mind that the head is printing a new layer every few seconds, curing it instantly with UV light. Solvents would not have time to flash off fast enough, even with the small droplet size. I would have to calculate how much heat would have to go into a droplet in order to flash it off fast enough but for various reasons I believe that to be highly impractical to deposit 20% “solids” or even 50% “solids” and then reduce it down. It is FAR better to simply print 100% solid, ultra low viscosity (almost as thin as water) material.The average polyjet resin is on the order of 400 – 800 centipoise at room temperature. So roughly 400 – 800 times thicker than water. Not quite molasses but starting to get up there. Too thick to jet with most printheads. Even the ones on their machines until you heat it up to 65 – 75 degrees C. Nearly 170 degrees F.To add insult to injury, at that temperature, you also run the risk of thermally curing UV if you keep it at that temperature long enough, no matter how many inhibitors you put in it. With the right material combination, it isn’t a big issue but just another thing to think about.",

Then again, many UV inks do not cure well in the presence of oxygen but that can be overcome with various techniques.

The support material is basically a hydrogel, similar perhaps to a contact lens if you want to think of it like that. It crumbles as you can see in the video. High pressure (500 – 1500 PSI) water is used to break most of the support material. Then you can soak it in lye/water to remove the last residue. Rinse and that’s it. Harder than say melting away a wax but not as bad as SLA or metal SLS (which involves a bandsaw to remove the printed item from the metal base and then dremel work to remove remaining support structures, if any).Average time to clean up a polyjet part depends on the complexity of the part. Big, highly complex parts may take 20 – 60 minutes. Especially if there are very, very small and therefore brittle parts. I would say an average polyjet part takes no more than 10 minutes of post finishing time.",

"content": "A HUGE amount has been written about UV curing chemistry. Books and publications and journal articles for over 30 years. It is, as with most things, complex to deal with but fairly simple to get the basics. The world of UV inks though is GIGANTIC. The amount of raw feedstock numbers in the thousands. That’s off the shelf raw material products available right now. Most are not suitable for use in UV inkjet chemistry for various reasons. But some things that make no sense in UV chemistry are what you need that only becomes apparent later. There are epoxy (BPA and BPF), urethane, polyester type chemistries for the oligomers as well as all sorts of different kind of monomers. Each one imparts a whole host of different properties on the final material and sometimes they combine in unexpected ways. Brittleness, adhesion, surface energy, viscosity, stiffness, tensile strength, elongation at break, surface tension, etc are all controlled by the selection of monomers and oligomers.Then there are fillers, pigments, suspension aids, dispersion agents, etc. They have to match the density or have the right functional end groups added to ensure stability… so you can see how the chemistry can start to get a bit complicated pretty quickly.The problem is sourcing the materials. Most vendors (and there are not too many out there) want to sell you a drum of material at minimum. You can’t just call them up and order a few pounds, although some vendors will offer samples at nominal cost. In general, you have to source at minimum, 3 different products (monomer, oligomer and photoinitiator) although realistically, the number is 5 – 7 or more to make an actual workable ink.Then, assuming you can come up with an ink, decide to buy 220+ gallons of it (at the cost of several thousand dollars), you have all sorts of other issues to contend with.You have to filter the material down to 1 micron or less, or else you will clog your nozzles. You have to be able to test and control viscosity across very exact temperatures. You have to be able to do real time droplet and satellite formation visualization to make sure the drops you are forming are accurately falling and recombining. You have to make sure the materials interface together properly. You have to source the industrial inkjet heads and build an interface to drive them.Once you source thousands of dollars of chemicals, you have to actually physically mix the ingredients together, which isn’t always easy. Some are powders, some are as thick as liquid glass and others are as thin as water. It’s not as simple as just pouring stuff together and stirring. Did I mention everything is UV sensitive?Then once you have it all together, testing is difficult because you need rigs to do UV exposure testing and you have to avoid UV exposure to your skin and eyes. I once got a nasty sunburn from only a few seconds of exposure. As bad as if I was out in the sun all day. You don’t even realize it until a little while later.So, in short, there is a fairly good reason why people have not been experimenting with UV chemistry just yet. Like most things though, it IS possible. It just isn’t easy, something you can do on a shoestring budget or something you can just start doing without getting at least a bit serious about it – investing in the right equipment and doing the right research.Which explains why a large X,Y,Z gluegun (makerbot, repraps, etc) are becoming so popular. The “ink” is a single, inexpensive component, which cures by cooling.If we can get a recipe list of where to buy UV inks (or a reseller who is willing to supply small quantities of either bulk purchased raw material or reasonably priced finished inks) so the guesswork is taken out of the ink process (AND the inks can be used in off the shelf printers due to room temperature UV jetting being possible) then maybe the rest of the issues could be tackled in due time as they are more of the basic details that have already been solved by cheap desktop printers and reprap style work.BUT, somebody has to invest the time into creating inks AND then decide to sell them for pennies. Not that I agree with the manufacturer’s decision to sell their inks for 20 – 40 times what it costs to make them (or more), I understand that the work that goes into their ink creation is substantial. Last I heard, Objet had at least 15 full time chemists on staff working on creating new inks if that gives you any idea as to how generally complicated formulating inks can be.Which, again, isn’t meant to be a discouragement. I repeat that I would absolutely love to see an open sourced UV printer and if the ink hurdle is tackled (which I believe I have done) then I see no compelling reason why something that would rival $150,000 machines in output quality could not be built for the low 4 figures range and run for very reasonable consumable prices.",

"content": "Sadly, Objet’s control boards are all custom made. There are actually several boards controlling them, including an embedded computer with a servo controller board. It runs windows and of course, the software is closed source. I am not sure if the arduino is able to control linear encoders and brushless servos well enough to be able to control something like this.Honestly, if you want to go DIY with as little fuss as possible, don’t even bother jetting materials. Just do the EnvisionTEC route and use a single DLP chip, an off the shelf projector bulb (which is what they use only they modify it slightly to make it harder to use – although it is still possible). Software like Magics can generate support structures for you, although it is closed source and rather expensive.If you go the DLP route, then you don’t have to jet anything. In fact, EnvisionTEC’s materials are better because they can do nano materials, with improved heat deflection, clearer materials, stronger materials, etc because they are not limited by viscosity like Objet is.Nobody out there is going to say this but I will. Objet’s dirty little secret is that while they offer a variety of materials, the materials they have are all “watered down” with monomers to push their viscosity into the jettable range. They can’t use the materials they would like to because they can’t jet them. Some of their materials are rubbery but the rubberyness is actually a side effect of lowering the quality of (by adding “thinners” aka monomers to (in this case) urethanes oligomer “strong” material. It doesn’t take much effort to rip or tear their rubbery materials.If the DIY community went DLP, just expose a layer, coat, expose, coat. No jets to break or clog. No fancy control for X and Y – an Arduino should have the ability to power it. Cheaper parts, especially given that the inks could be made outside of Objet’s ink patents. Faster (build the entire model layer at once vs do strips), larger build envelope (you could even trade off quality vs speed if you wanted to), higher resolution (seriously, the resolution in X and Y is better than Objet’s and has the ability to scale better as higher resolution DLP becomes available).The only downside? The single resin and lack of support material, which means supports have to be removed by hand. Not too terrible really – you can always sand off the support connection points – but if the geometry is complex, you can’t get around the fact that it is going to leave SOME marks and it is going to take SOME time to do so.But in the end? For Ultra High Quality, fairly cheap materials, cheap to build machine? Totally worth it. If it were me and I wanted to advance the state of the art in 3d printing, I would build an open source DLP based machine using UV resins. Not sure if a reprap would be able to make parts for it, but a machine like this would quite literally have the quality and resolution to print most of the parts for other second generation machines. Slap in an arduino, DLP chip, projector bulb, a Z axis motor and a control board and you just copied a machine.And if you bumped the quality down and the thickness up, you could make something with straight walls VERY fast, even if it was fairly large (larger than most commercial build envelopes, save for very large format SLA machines). You could even speed it up when making things where stairstepping wasn’t an issue (like a case that just needs to be X inches deep) and then slow it down for curves and detail work. I don’t even think the commercial machines do that.",

We’ve had a few folks send us info about their vehicle display hacks after seeing [Will O’Brien’s]
motorcycle computer
a few days ago.
On the left we have
a display for an electric vehicle
. [S1axter] is using a 4.3″ TFT screen to display charge information for each battery cell in the car. An ATmega88 collects the data and sends it to a breakout board with an LCD controller on it.
To the right is a display from
a Formula Student project
. a Matrix Orbital GLK19264-7T-1U LCD display provides a lot of real estate for displaying data. Right now [Alan] is still in the early prototyping stages, but the video after the break demonstrates the RPM readout using a function generator. It’s not shown in the video, but he tells us that he’s since tried it out with the engine and has a PIC 16f877 reading temperate data from the electronic control transmission sensors in addition to the RPM data.
Correction:
Thanks to [j] for correcting our mistake. This is
a Formula Student car
.

There wasn’t really a ghosting problem, though it was only displaying the speed in large digits – perhaps finer details would cause problems. But the biggest problem with the regular glass was that, in summer in bright sunlight, you wouldn’t be able to read the display.On the bright side, it should be possible to get more HUD-friendly glass installed in your car if you’re planning to experiment with such a system. IIRC, it’s not _too_ much more expensive than a standard windshield replacement.",

If a picture is worth 1000 words, by our count, [
Ryan Commbes
] has said 1.68×10^6 different things about his custom
robot
, airsoft, and
monster truck
builds. While we’re not ones to pick favorites, we agreed his
Alpine TPG-1
(picture at the top) build is a step above the rest. Sadly,
the forums
with his build log doesn’t seem to be loading, but he says the basic process if you wanted to make your own is to gather pictures, measure, and create.
[Thanks Andrew]

Since 2 years ago you have to be a member of an airsoft club to BUY a gun, but ownership is entirely unrestricted. And whilst most sites limit their playable muzzle fps to around 328, this is entirely voluntary and some sites have much higher limits (usually only for sniper rifles & co).",

Classic Canon AE-1 Gets A Digital Upgrade

Shots of this
Canon AE-1 camera-gone-digital
have a lot of people scratching their heads. Originally there were a lot of “that’s been photoshopped” cries but the video after the break shows that it physically exists. This
particular model of camera
hasn’t been manufactured since 1984 so there’s little chance that the company’s bringing it back in a digital format. What we have here is a classic camera body with a modern point-and-shoot fit inside. This seems to be a PowerShot SD 870 IS and we’d guess the original lens has been replaced with a plate of glass so as not to affect the PowerShot’s focus, and the “AE-1 Program Digital” screen is probably just an image on the memory card.
We admire the clean mod work necessary to produce this hack.

AE-1’s were nice in their day but it’s not a super rare or expensive camera. That said I have many older cameras (including a similar AV-1) that I would never even think of doing this to.",

It’s sort of collectible but I can’t fathom why anyone would buy one now to actually use it, unless it’s digital Canon brandwhores who don’t know anything about film cameras. I used one in school and was more than happy to ditch it for a Nikon FE as soon as I graduated and got a job (the FE’s not ideal, I wish it was an FM3A).I agree it’s silly to hollow out a working camera just to stick another one inside it, but if you’re going to trash an old SLR better an AE-1 (they’re common as dirt) than a true classic like an FM2 or an OM-1 or K1000. And far better to smash our Canon optics of that era than Nikkor.",

Custom PS3 Controller: Software Emulation Version

[Matlo] posted a tutorial that will walk you through
setting up a six-axis controller emulator
. In April he developed
a hardware solution using the Teensy
but this version just needs a Linux computer with a Bluetooth adapter. If you don’t mind adding a computer to the mix you can use any peripheral controller that will talk to Linux and then adjust the six-axis PS3 controller mapping accordingly.

Want
21 megabytes more ram in your Nexus One
? [Coolbho3000] worked out a way to tweak the kernel and remap memory usage to free up some resources. That means this comes as a custom kernel image requiring no hardware alteration. Try it out and share your experiences in the comments. But if you don’t need more ram you can just
upgrade to the most recent kernel
.

I’m going to break from the typical Hackaday article format for a moment. I’m smitten, captivated by this wondrous new discovery. Forgive my ignorance for having never seen one of these before, I didn’t go to school for electronics. For those, who like myself wondered, what is this beautiful glowing thing, it is a
mercury arc valve rectifier
.
This is not some chintzy attempt at neo victorian styling (steampunk if you absolutely must), this is an actual piece of electronics used in the field. Widely used to convert alternating current to direct current for railways and street cars, these could actually be found in the wild. There was a time, that opening a door in a power station would have presented you with this fantastic green and purple glowing orb, dripping mercury sparkling inside. If you are anything like me, you would most likely have been frozen in your tracks, convinced you were bearing witness magic.

Ever wondered how expensive versus cheap multimeters hold up to abuse? [Dave] gives us a pretty good idea by, well,
blowing them up
. He’s using a capacitor bank to put roughly 4.2 KiloVolts into the poor little meters. If you absolutely must skip to the multimeters, go to about 5:00. You really will miss out on some good stuff though.

Yes, I’m aware that if you overload something it might go pop, but the expensive and cheap beters both did that, so no real difference there.What other disadvantages are there of cheap meters?

Accuracy may be an issue, but I think most claim +-0.5% to +-1.5% on their datasheets, and for most stuff I do that is plenty good enough.I do find the leads of cheap multimeters keep breaking, but I suspect the expensive ones would do that if I treated them the same…",

The answer was in the Fluke adverts, the fuses are full of sand, they are supposed to fuse into glass and prevent a plasma fireball at 15kv.It was accompanied by a ~16″ diameter plasma explosion picture.I made up some test leads with standard 3amp blade fuses for those meters.I usually wait for the $1/$2/$3 multimeters at Harbor Freight, compared to the Flukes they were plenty accurate.

PVC hull, SLA batteries, Bilge Pumps, sounds like a good start to [Jimmy’s]
ROV project
. Paintball gun (as a BCD), dual live cameras paired with an Arduino making it internet controlled, all tethered with a fiber optic cable, sounds like [Jimmy’s] ROV got a whole lot more astounding.
While some very important parts have yet to be implemented, like the leak detectors, the project looks to be going quite smoothly. With updates promised, we can’t wait to watch this continue until the end.

Quick, go to
answers.hackaday.com
and sign up for an account. Ages ago,
we announced
that we would be bringing a community driven question and answer system to Hackaday. We eventually got tired of waiting for the feature to be provided and
improvised
. Well, the wait is over. You can now post your own questions and answers. Go nuts, post away, but remember to be respectful. We’re still figuring out this system ourselves, so be patient with us as well.
Be warned, we’re going to be pretty strict on trolling.
It is worth noting that there is a money system integrated into it. This means that you can offer a real reward for answers to your questions. You certainly don’t have to though.

Paintball Graffitti

Paintball as a large format printer? That’s exactly what
facade printer
is. A paintball gun was mounted with two controllable axes of movement. A computer reads in the image data and prints it out by shooting paintballs to form a dot-matrix display. There’s a couple of wins here, the paintball paint can be washed off, and this will work on coarse or uneven display medium. Check out a video of the printing process after the break.
If you already
built your own paintball turret
, give the other guys and chance and hack it to print instead of gunning down unsuspecting adversaries.

I don’t know whether you’d want Yellow first or last. That would be the experimental phase. But it could work.",

Laser Command Game Uses Laser For Control

[Eliji Hayashi’s]
project for a class at Carnegie Mellon
University is absolutely delightful! It is a game he calls Laser Command because a laser pointer is used as the gaming controller. An 8×8 LED matrix serves as the display, but is also used as an 8×8 light sensor, much the same way as
the LED advent project
did. The display is rapidly switched between producing light and sensing it. The laser is bright enough that it becomes easy to pick up the voltage generated within the matrix during the sensing periods. The game is programmed on an Arduino mini and the whole thing wraps up into an incredibly small package. Brilliant.
[Thanks Juan]

Print Toner Directly To A PCB

We use the toner transfer method to fabricate printed circuit boards. The most difficult part of this is printing, ironing, and removing the paper from the toner that is used as an etchant resist material. [Mark Lerman] is developing a method to
apply toner directly to the copper clad using a laser printer
. Each of the photos in his gallery have comments that take us through his process. A laser printer has been modified to negatively charge the copper plate, thereby attracting the positively charged toner to it. Once the toner has been applied, the board is baked in an oven, then run through a laminator. This process can yield 2 mil traces and it looks like the potential for incredibly clean boards is just around the corner. The question is, will this be easier and take less time than using photo resist?
We’ve contacted [Mark] in hopes of getting more details. If you can’t wait for a follow-up,
take a look at this thread
concerning his work.
[Thanks Komradbob]

I have turned out boards in 10-15 minutes from the time I finalize a board design. Makes doing prototypes and proof of concept and little things really easy. No intermediate steps.Never mind most of the stuff I find myself prototyping now is surface mount, which means no through holes to drill (bonus) and very fine pitch packaging. Not such a big bonus when it comes to photo based processes.@AKASteve – The laminator is used to fuse the toner to the copper board. You don’t laminate on a plastic layer.@James: – The issue is keeping the ink flowing. indelible inks tend to be much thicker than water based inks.I use a plotter based method but I can’t get much below 0.035″ lines without going to toner transfer, which has other issues. Direct printing (which I have also done, he just writes it up far better) works great. If I have time this weekend, I’m going to see if direct print method can be used to create solder masks for surface mount packages using thin brass or aluminum sheet.",

It takes about <1 minute to print out the design, <3 minutes to mount it in my UV exposure box and expose to UV. And while it's exposing I pour the developer, and dump the board directly in that for a few minutes. While that's devloping I mix the etchant using HCL and H2O2 and transfer the board to the etchant. That takes about 4 minutes for a 3×5\" board and from there I wash it off and remove the photoresist, which takes maybe 5 minutes. I do most of my boards with SMT so I don't have to drill many holes after that. The whole process takes roughly 15-20 minutes to produce a board if you have the process down like do. Obviously this is an oversimplification but my point is that for the time and effort, the UV method is vastly superior to toner transfer, and I can get down to 2mil traces.",

It takes less than 15 minutes from the time I click print to to when I can begin placing components. I use almost entirely SMD components so I don’t have many holes to drill except power and other copper wire connections. I’m now almost exlusively using flexible FR4, but I can print rigid boards just as easily.I prefer the flexible FR4 because I can get 15 8×10 sheets for about $10 on eBay, and I can cut it to shape with a pair of scissors. The fuser in the printer wasn’t capable of fusing the toner to the board, so I just use a small butane torch or lighter to fuse it. I use the sponge wipe method to etch them, and the toner remains in place perfectly fine without lifting or breaking! I’m going to be doing a write up, and making a video for Youtube as well.I did a quick write up for a friend a few months ago when I first started fiddling with it. The page is outdated in that I since discovered that the fuser won’t work. The only picture of a printed board on there was just a test and was never etched. I will make another page on my website in a few days showing some of the capabilities of the printer.My last board I etched just last night was a spiral of 3 mil traces with 3 mil spacing. The board is about one inch square. I estimated that the trace is about 11 feet long total, and gives me a resistance of around 10 ohms end to end.The link to my outdated page is:http://www.foxau2.com/laser.html",

Take a few minutes to watch this amazingly informative video on
how to solder QFN or MLF components without solder paste
. The quality of the video and the information within is quite nice. Even if you don’t intend to work with these parts, you could pick up some tips for soldering with hot air.

It works better if you use lead-based solder: enough capillary action to self-center the part. Also, Metcal sells one tip with an end radius of like 0.16mm, fine enough to touch the exposed metal on the sides of some QFN’s so you can reflow to the pad. Also also, you can often check continuity on individual leads by checking for the reverse body diode drop from a lead to ground. Also also also if you have a two-sided board, you can load the difficult parts on one side, then take a reasonably thick piece of aluminum plate and cut out holes where those parts live, and put the board face-down on the plate on the hotplate and load qfn’s on the topside as well.",

This
prosthetic arm
is the result of a student project. [Amnon Demri] and his classmates built it with below-the-elbow amputees in mind. It uses
electromyography
to actuate the fingers and wrist. Four stick-on sensors are placed around the elbow to sense electrical activity there. These signals are interpreted by a PIC 16f877a microcontroller which then controls the servo motors to operate the prosthetic limb. This sounds like a very economical solution and as you can see in the videos after the break, it works fairly well.

[Meseta] built
a powerful boost charger
to top off his portable devices. He was inspired by the
Minty Boost
but wanted to overcome the rather limited capacity provided by the two-celled product. He ended up building his own DC to DC boost circuit rather than using an all-in-one IC. As you can see, the result uses four 18650 lithium-ion cells, normally found in laptop batteries, and can power two USB devices at the same time.

One is to shunt the current over a cell once a certain voltage is reached. Another is to have each cell charged separately. In a series configuration, you always have to play by the weakest link, and once you detect one cell going under the safety limit, it’s full stop for the entire battery.With sensible load currents, having the cells in parallel will not see any of them draining so fast that the others would dump uncontrollable amouts of current into them. Same thing with charging. Besides, lithiums do tolerate high currents both charging and discharging. It’s the excess voltage that they don’t like.If you’re charging a 4 cell pack limited at 0.5C, the worst thing that happens in the hypothetical situation that three cells disconnect completely, one cell would get 2C. It should be able to handle that.RC packs made with NiMh cells can take some punishment without dying immediately, even to a point where a cell could reverse its voltage and still come back after a recharge. Lithiums don’t work like that. If you step out of the safe zone, the cell is dead.",

I was thinking more MP3 players, cellphones, etc. . .where power management is pretty important, and is the dominant compromise. You typically see a step down or two for the different voltages needed (1.8-ish, from 3.7v). You’re right about step ups typically being more expensive than step downs for the same power load, and that’s partly because you’re doing more current instead of voltage (so i2r losses in the mosfet & inductor, thicker inductor needed, and more expensive mosfet needed)It’s probably less of an issue with lithium-ions–perhaps they are better matched and better capable of handling those currents. I have never attempted to work with them in parallel–only in series with charge balancing. Certainly I’d imagine one battery charging the other would shorten the battery life (it’s essentially unnecessary charge cycling), and would make the single charge life lower because of the i2r losses in the battery while one battery charges the other. It’s definitely something I avoid (in general, too) but even more so for replaceable batteries when designing anything consumer oriented, because you know someone’s going to put a dead battery with a fresh one, and if they’re in parallel one’s going to charge the other one to death, and possibly start a fire. we try to avoid the lawsuits as much as we can ;)In the end, in this particular case, I don’t think anyone could make a very strong case that putting the cells in parallel with a step up is better than putting them in series with a step down.",

And it’s great to see all the constructive criticizmsI would like to just defend some of my decision:To make things clear: this does not charge 18650 cells; it uses 18650 cells to charge other devices via USB cable.I use parallel cells because the circuit is designed so that it can work with a single cell (and hence why I have decided with step-up although I had initially designed the circuit based on the SEPIC topology)I have decided to not use battery balancing because I’m charging batteries externally using a dedicated charger (charge balancing is not as important for discharging). and as Einomies mentions, they balance themselves out (also Li-ion have a 80-90% charge efficiency vs. 66% of NiMH according to Wikipedia)@threepointone you will find that laptop batteries are wired in parallel before series).@Andrew: I agree with you! However, here’s what I actually said: ‘Unfortunately, because they’re “micropower”, they’re not designed to output higher power’.There are plenty of Monolithic DC/DC ICs that handle higher power outputs, and I had originally thought about using the LT1707, which will do 10A at 5V.

"content": "“Certainly I’d imagine one battery charging the other would shorten the battery life (it’s essentially unnecessary charge cycling)”This is a problem with NiMh and NiCad chemistries. Lithiums don’t have significant self-discharge, which would cause one weak cell to drain the entire pack. The weak cell would be topped up, and then the current stops flowing. If it starts to truly leak anything and heat up, the internal fuse will blow and the cell disconnects.You control lithium cells by voltage, not by current like with NiMh. The voltage of a lithium cell is a very good indication of the state of charge. It’s not linear, but generally you can plot a curve where n Volts equals m Amp-hours remaining. The only thing that affects the voltage beyond that is the V=RI of the internal resistance, so the cell voltage reads consistently higher or lower depending on the current going in/out.This is much unlike NiMh which exhibits weird spikes and voltage drops depending on the current going in/out and the state of charge at which it happens. Knowing the voltage of a nickel cell doesn’t help, and the varying voltages mean that the currents keep circulating inside the pack.That’s the reason why parallel lithium pack tends to self-balance, because any cell that lags behind in voltage tends to get charged faster until it catches up, and any cell that gets full faster than the others will have its voltage up, and that diverts the current to the other cells. Likewise in discharge, weaker cells get drained slower and better cells get drained faster, leaving all of them in roughly the same state of charge despite the differences in capacity, so a parallel configuration is very suitable for lithium cells.Because lithiums have tight tolerances in acceptable voltage levels, they’re difficult to use in series configuration because you have to stop once the weakest cell runs out of voltage. All cells in the series are then essentially the same size as the weakest cell.",

DIY Pulse Oximeter

"pulse oximeter"

This
pulse oximeter
turned out very nicely. It is based around a Freescale microcontroller and detects pulse as well as oxygen saturation in your blood. The sensor is made of two wood pieces and allows two wavelengths of light to be shined through your finger. A sensor picks up the light on the other side of your stubby digit and the readings are compared to calculate saturation. Check out the finished project after the break.
We saw
an Arduino-based oximeter
a few months ago. These kind biometric hacks are rare around here. If you’ve got a
well documented
project don’t forget to
tell us about it
.
[Thanks Michael]

Motion Sensing Light Module

[Muris] is pumping out the home lighting hacks. He developed
this motion sensing module
as an add-on to the
IR switch we saw last week
. There’s some kind of fuse box above his entry door and its white cover, which you see above, is where he mounted an IR distance sensor to detect movement and switch on the lights. The RC5 infrared protocol is used to transmit the necessary signal to turn the lights on, then when a set amount of time has passed it will turn them back off again.

One complaint we hear about often is ear-bud’s cables getting tangled within backpacks. [Andrew]
was having
this “spaghetti” wire problem, and also wanted to listen to his music with ear protection on – where ear-buds are usually uncomfortable. The latter problem is fixed by placing speakers inside of folding ear protectors, and the cable is managed with a 3.5mm disconnect.
For those who can’t make disconnect-able headphones but still suffer from tangled headphone wire, we recommend
proper wrapping technique
for your wire, and a
small carrying pouch
. With the combination of the two, we’ve never had a tangled cable.

These two steps mean you unvelcro and disconnect the cable, the wrap can be thrown from either end because both of them are on the outside of the wrap and not through the center. If you are super paranoid, you can also throw the coil holding onto the ends with the ends still connected which will also lead you to have a perfectly laid cable that is still connected to itself.Long story short: Uncoiling cables is more vital than coiling it, if you aren’t paying attention to what the coil state is you can end up with knots regardless of how it was coiled. This is especially important if you are dealing with cables that you didn’t wrap yourself.",

Above is a new demo video called Phasor developed by [Lft]. It is run from an AVR ATmega88 and a few passive components, and the result is pretty amazing. [Lft]
goes into detail about the tricks
he used to get this up and running. The chip is clocked at 17.73447 MHz which is exactly four times the frequency of the PAL color carrier wave which allows him to fake a smooth signal. He also uses a timer trick to get the voltages that he needs. The work done here is beyond hardcore and quite frankly we can’t believe he managed to fit all of this into 8.5 KB of program space with just 1 KB or RAM. We wonder if there’s enough room there to add sound and color to
the AVR Tetris project

DPAC Put Your Alarm Clock To Shame

DPAC,
the Dynamically Programmable Alarm Clock
, goes far beyond what you would expect an alarm clock to do, yet we find all of its features useful. You can see there are four buttons at the bottom that control the menu scrolling. The second from the left currently reads “Sync”, a feature that the clock uses every 10 minutes but can be forced manually. This will check your Google Calendar, schedule an alarm for the next event while factoring in driving distance, traffic, and weather conditions. It’s got an audio system for radio and iPod operation, but also includes some home automation options. Using the X10 communication protocol it can turn on lights, start the coffee maker, and open the blinds as part of a gentle wake-up cycle. All of this is configurable through the clock itself, or via the web interface. The prototyping was done on an Arduino but the final version uses an AVR ATmega324 along with a Roving Networks RN-134 WiFi module (
datasheet
) for connectivity. Check out the demonstration video that [Eric Gaertner] and his fellow developers filmed after the break.

CPU As A Heat Sink

"openwrt",

] |
We’ve noticed that wireless routers pump out a bunch of heat. [Jernej Kranjec]
wanted to make sure that he didn’t fry it
once he started adding more load to his router using OpenWRT. What he came up with is the idea of using an old CPU as a passive heat sink. He applied a bit of thermal paste to the center and some super glue to the corners. You can see the finished product is an old AMD chip adhered “dead bug” style to the stock processor. We’d bet it’s not very efficient compared to an aluminum or copper heat sink, but it normally would have no help in shedding those extra degrees.

The pins are obviously insulated from each other, and their connection to the die itself is not going to move much heat energy.Popping a few more holes in the case and putting in a small fan would have been a lot more effective.",

"content": "It seems some people need brush-up on their thermodynamics theory. Couple of notes:1. When a greater mass is heated, it means the mass stays cooler longer, but it also retains heat longer when the external heat source is removed. That does not imply the mass will have a hotter operating temperature, that entirely depends on the nature of the surface area which is in contact with the air. In short, doesn’t matter what you use as a heat sink (provided you can transfer heat adequately); greater mass == more work to heat it up.2. CPU packages are designed to be fairly efficient in drawing heat away from the substrate onto the outer case, onto the pins, and also the metal plate which dumps heat onto a heat sink. The reverse is also true when the heat source is applied externally on the CPU case.3. Ceramic materials can be good heat conductors. Not as good as pure copper, but infinitely better than many insulators. It’s one of the reasons why they were used in early CPU packages and why you see them in high power electronics.",

[Csaba Bleuer] has built this really nice
POV LED sphere
. Looking at the hand drawn schematic, it appears that he’s using an Atmega8 as the core. The resolution is pretty decent, and even shows fairly well on camera despite the refresh issues. Although much cleaner, it looks like a similar implementation to
this one
that we covered back in october of last year. He’s still got some polishing to do to match “
the orb
” though.

IPhone 3.1.3 Unteathered Jailbreak

A method to
Jailbreak the new 3.1.3 iPhone rom
is here and it does away with tethering. Tethering is the problem that arose from the blackra1n exploit requiring a computer to reboot the iPhone. Although we saw
a hardware workaround
for that, it’s much nicer to do away with the issue completely. The new exploit is called Spirit and we found the site was getting hammered earlier so you should check out
the writeup over at Redmond Pie
if you can’t get through with the link at the top.

Automated Chicken Coop Door

Here’s a pretty cool implementation of an
automated door, built for a chicken coop
. The electronics are fairly standard, an Arduino and a used cordless drill. The end product will be not only wireless, but automated based off of ambient light as well. We also found the locking mechanism quite elegant. He also supplied a link to
another automated chicken coop door
which has a decent writeup with schematics and such. Next, he’ll have to
automate their feeding
as well.
[Thanks Jeri]

Opening the door at the crack of dawn (when I’m fast-asleep) was the real driving reason for this project.",

I’m working on using the feedback for something useful – possibly a stuck chicken-sensor? What’s interesting is that I can see the PWM affect the feedback values.I was going to roll my own H-bridge, but realized that error conditions could cause blue smoke without smarts.Ultimately, I want to get some cheap H-Bridge controllers and then use mosfets scrapped from mainboards for the high-power section.At top load, the motor draws just under 5A (6v), which this controller can handle for up to 30 seconds. The door operation is much more brief than that.@spyder_21 – love the peck-to-open idea.",

VirtualBox Beta Runs Mac OS X

A new beta build
of
VirtualBox
,
Sun’s
Oracle’s
free
x86 virtualization software, makes it possible to run Mac OS X as a guest operating system…no shenanigans or flaming hoops to jump through, just pop in the $30 retail Snow Leopard upgrade disc and go. This had previously only been possible with some awkward
Hackintosh
-style maneuvering, or using recent editions of commercial
virtualization
products.
At this early stage, performance is fairly sluggish, the screen size is fixed and there’s no sound support, but the OS otherwise appears to run feature-complete (including networking and USB). Hopefully future builds will ramp up to the level of functionality and performance that VirtualBox provides for other guest operating systems.
Installation tip: when you come to the step prompting for a target disk for installation (which will likely show no available volumes), run Disk Utility from the “Utilities” menu, format the virtual disk image you created when setting up the VM (Mac OS Extended, Journaled), then exit Disk Utility to return to the OS X installer. You can then select the newly-formatted virtual disk and proceed with installation.

[William Etter] and his classmates
built a quadcopter as a class project
. We love the details of these builds and they came through with some thorough documentation. Some highlights that we enjoyed were reading about
ABS body design
and construction, their
analysis of two versus three blade propellers
, and their
breadboarded control mechanism
. You can
see their success
in the most recent post, but we all know that trial and error plays a role in these builds so we’re glad they’ve shared
a collection of crashes
with us.
Can’t get enough of this four-rotor action? Check out
this project of a similar design
.

The possibility of making this a kit that will allow people to have a stable platform for more advanced projects (or just strapping a camera to it and having fun!) is also being looked at.Thanks!-William",

Challenged by hot days and steep turf [Grayson Sigler]
modified his reel mower to use electric motors
. The end product will be radio controlled but he lacked the necessary parts to make it wireless right now. Not to be deterred, he used a wired controller for prototyping and testing that should be easily replaced once the parts arrive. Sadly, the grade of his yard causes the small wheels to slip so he tried inserting screws into the tread for added traction. The small mower lacks the weight and footprint that
the Lawnbot400
enjoys. That being said, solar charging is one of the future goals so this build, which he named RoMOW, wins out on the green scale. We’ve included the prototype video after the break that shows the blades spinning away.

Headphone Tube Preamp Kit

If you’re curious about tube amps but don’t have a firm enough knowledge base to dive right in you might want to try a kit. [Mark Houston]
reviewed one such kit
and we enjoyed reading about his experiences. It comes with everything you need save soldering tools, an enclosure, and the final connectors ([Mark] used RCA connectors). There is a full schematic available and the assembly instructions take you through tube matching and using that piece of copper coil you see in the picture to wind your own inductor. Consider trying this primer before you jump into building a
single tube
,
multiple tube
, or an amplifier of your own design.
[Thanks Gio]

Hackaday writer of yore [
Will O’Brien
] has been working on this
hardware for his motorcycle
. Speed, voltage, gear, and temperature data is displayed on a 16×2 character LCD. The speed is pulled from the bike itself and the gear is calculated by comparing engine RPM to wheel RPM. He’s using
the popular DS1820
1-wire temp sensor along with an Arduino to pull everything together. At this point he estimates there’s about $50 worth of parts, but that can be reduced by etching a board and just using the necessary components.

The sensors will all be wired to a Silicon Labs C8051F340 MCU (it has USB for firmware updates and datalogging), which will collect sensor data and stream it out via serial. On the other end of the serial line will be my Android phone, which I will dock into the handlebars when I’m ready to go for a ride, and will have a cool UI. I’m also considering some anti-theft measures, to where the bike will only start if the phone is plugged in and sends the right “key” to the MCU, which will then enable the ignition system.Add in a stereo bluetooth headset into my helmet, and I’ll have my dashboard, GPS navigation, phone, and music all in one!

If you can store that data to memory, it could potentially be used if (God forbid) you’re ever in an accident. If you weren’t driving recklessly and the data is collected at a high enough rate, you could probably use the data to help your case. If you can show that you weren’t making aggressive gear shifts and your speed was within limits – that could really help prove whether or not you have partial responsibility.Personally I would opt for having a display – my bike shows very few metrics, so I’m pretty sure a little number won’t start a helmet fire.I really like this idea, it makes me wanna work something like this up for my bike!",

Adding Reset To An FTDI Cable

Hackaday alum [
Adam Harris
]
hacked an FTDI cable
to use for programming his Arduino. After cracking open the plastic case he found the FTDI chip used is the same as the one in
the SparkFun programmer
. The only real difference was that his cable wasn’t resetting the Arduino, he had to do that manually. The solution was to reroute the RTS wire so that it connected up to the DTR pin. This proved difficult because of the tiny footprint of the chip, but after many tries he managed to get a piece of wire wrap soldered in place.

Using A/C Frequency As A Clock Signal
|
Mike Szczys

[
"clock hacks"
] |
[
"clock",
"frequency"
] |
A while back
we saw a logic clock that
used the alternating current frequency from the power grid to keep time. We asked for information on your projects that use this method and we got a lot of comments and tips. Today we’re sharing [Doug Jackson’s] method which he used in
his word clock
.
The
schematic above
is from that project and we’ve outlined the important part in green. [Doug] pulls a signal from the 9V AC power before it hits the bridge rectifier, using a 100K resistor and a zener diode to protect the microcontroller pin. The code for that project comes as a hex file but he sent us the C code pertaining to this timing circuit. It’s written for PIC but you’ll have no trouble adapting it to other microcontroller families. Take a look after the break.
// Set the frequency of the local mains - MUST BE SET OR THE CLOCK WILL BE USELESS
//#define MAINS_FREQ 50 // the local mains supply frequency for Australia
#define MAINS_FREQ 60 // the local mains supply frequency for the USA
T1CON = 0b00000011; // Timer 1 control
// Prescale - 00 - 1:1, Oscilator disabled, External Clock, Timer Enebled
void incrementtime(void){
// increment the time counters keeping care to rollover as required
sec=0;
if (++min >= 60) {
min=0;
if (++hour == 13) {
hour=1; }
}
}
void interrupt my_isr(void){
// test to see if it was a Timer 1 interrupt - External mains source
if ((TMR1IE) && (TMR1IF) && (mode==0)){
sec++; // increment the seconds counter
TMR1IF=0;
TMR1H=0xff;
TMR1L=MAINS_DLY; // reset TMR1H and TMR1L to go off in the
// appropriate number of cycles based on the local
// supply frequency
}
}
void main(void)
{
init(); // initialise the hardware
testleds(); // test the LED array
version(); // Display the version number of the software
displaytime(); // display the current time
TMR1H=0xff;
TMR1L=MAINS_DLY; // reset TMR1H and TMR1L to go off in the number of
// mains cycles based on the local mains frequency
ei();
while (1) {
//test to see if we need to increment the time counters
if (sec==60)
{
incrementtime();
displaytime();
}
....... etc etc etc - do the display of the time as required.....
}

In other words, short-term the frequency drifts significantly but the long-term accuracy isn’t bad. Obviously if your power goes out, though, all bets are off; a home generator is probably lucky to stay within +/- 10% of the correct frequency.One useful point is the circuit as shown will probably only work reliably if the IC being driven has Schottky inputs.

We’ve seen several different balancing bot styles over the past few years, but this one is new to us. The
BallP, short for Ball inverted Pendulum
, balances on top of a ball. We’re not sure what the advantages are to this layout though. Anyone care to enlighten us? Even though we hadn’t seen this style, it is apparently not new. The
Ballbot has been around for a while
and might seem even more impressive visually.

Optiboot Makes Your Arduino Faster, Sleeker

"bootloader",
"optiboot"
] |
Tired of waiting for that Arduino sketch to upload? Find yourself limited by code space?
Optiboot
eases both of these problems. The package is an alternative bootloader that runs at a higher baud rate (115200 versus 57600) and it takes up 1.5 KB less space than the stock version. This means your sketches can be larger without upgrading to a beefier chip and they will take less time to upload, a lot less.
This fully compatible alternative to the Arduino bootloader requires an AVR ISP programmer to burn it to the chip on your Arduino. If you have an extra AVR lying around you could
use the Arduino as a programmer
and then physically swap the chips.
[Thanks Peter]

However, the bootloader has shrunk by 75%. There are lots of interesting optimisations happening in the source and build process to produce code that tight.Jerome and others: Yes, it isn’t as fast as an ISP programmer. Yet. However, it is getting pretty close. Programming happens at 115kbaud. It takes 9ms to erase and reprogram a 128 byte flash page – that works out at a 142kbaud theoretical maximum. When the Arduino IDE updates its Avrdude package, there will be an Optiboot release supporting 250kbaud, and then it will be as fast as any commercial programmer.Tom: Sorry you had build problems. Optiboot inherits the Arduino bootloader makefile, which is ‘unusual’. Check the ‘makeall’ script – that should get you started.Alexander Rossie: Best comment EVAR!!glitch: Sorry you had programming issues. I haven’t seen those sorts of problems – but I’d like to work with you to fix things and update documentation/software as appropriate.

[Carmine] let us know about his team’s
Automated Football Launcher
. Their goal was to combine a football launcher with motion tracking, to allow a player to practice running and catching with the perfect throw. Unfortunately, and we’re not quite sure
when
, they ended up changing out the
Jugs machine
for an air cannon, which resulted in the use of foam footballs and the loss of throwing factors such as spiral. Somewhat defeating the purpose but we’ll let it slide; only because we know its going to be shooting
potatoes eventually
.
The project comes together by using two cameras giving distance and color tracking, combined with a rotating platform (and the best use of garden hose ever), an accurate set-top for their launcher. As seen in the video after the jump, it works out quite nicely.

"content": "It always bothers me to see the low quality/dangerous air cannons that appear here, especially in contrast to the usual amazing craftsmanship that is the standard here.Even _pressure rated_ PVC is not designed to carry pressurized air, just pressurized water, (Pressure is pressure for the purposes of material failure point, but the energy contained in a volume of compressed air is much higher than a volume of water because it is far more compressible) though that in itself isn’t terribly damning.However the reducers that they are using aren’t even pressure rated, they are DWV rated (drain/waste/vent), these are cell core, not solid core PVC and are dangerous to use in pressure applications.Safety considerations aside, the use of a solenoid actuated sprinkler valve is severely limiting their performance. At the very least modding the valve to be pneumatically actuated would make the valve open perhaps 10-20 times faster.Additionally, sprinkler valves are chamber sealing diaphragm valves and limit flow quite a bit. If you need a drop in commercial solution QEVs are leagues better and may actually be even cheaper than the sprinkler valve. If you are willing to spend an extra hour on construction you can easily build a piston valve (with no machining or special parts required, just some creativity) that will have millisecond opening times and will have no flow obstructions.A higher performance valve will enable lower operating pressures (maybe as low as 15-20 PSI) and a much smaller pressure chamber (maybe 4 or 5 times smaller than what they are currently using). This means greater launch frequency, increased operating safety, and a far cheaper/quieter compressor.Those interested in serious design/construction of air cannons should check out an excellent tool called the Gas Gun Design Tool (GGDT). Just google GGDT, it’s the first result, or seehttp://www.thehalls-in-bfe.com/GGDT/",

9 Digit Pulse Counter

At roughly $20 to build, this
9 digit pulse counter
is an excellent example of home built tools. The builder, [Josh] found himself repairing a device and in need of a pulse counter. With the components cheaply available, he just built his own. He says that it has a few limitations, like display brightness, but overall it seems to do the job well. You can download the PCB from his site.
