Gift-giving season is upon us, and it’s time for people to start panicking about what to give to their friends and families. Gift cards have gained in popularity over the years, as companies count on people to forget to use them. But how about gift cards that do more than store a token amount of cash? Best Buy is now selling a
gift card that doubles as a speaker
. It has a mini headphone jack that’ll plug into any audio player. You only need to spend fifteen dollars to get it. Target’s gone all out, with a
gift card that is also a 1.2 MP digital camera
. It comes with a USB cord and driver disk, and there’s even one with a
64MB USB flash drive
. We’re very interested to see if these will take off, and what people will do with them once the cards are used up.

Super Nintendo Clock

[Aaron] sent us this sweet
Super Nintendo Clock
that he built. When he found himself with a broken SNES, a friend challenged him to
out do his previous NES
clock. This time, the display would be located in the cartridge, and removable. Setting the time is done on the SNES controller and seems to work pretty well as you can see in the video after the break.
[youtube=http://www.youtube.com/watch?v=eoqRfSjfAIc]
Now that the display is removable, he needs to build different displays. How about a laser projected display?

[nico] just received his credentials for an upcoming conference. On each badge, there’s a 2D barcode with the participant’s bio and contact info. These are meant to be scanned by vendors for future contact. [nico] isn’t so interested in that and plans on updating his personal info by generating a new barcode. To this end, he’s
collected a number of links to help out barcode hackers
. He used the
SWIPE toolkit
to identify the format and decode (it has an
online component
too). There are also several online encoders you can use,
like this one
from [Terry Burton]. If you’re wondering what sort of shenanigans you can get into faking barcodes, check out [fx]’s
presentation from 24C3
.

With a new administration coming into power, the Electronic Frontier Foundation feels that it’s time for a change (see what we did there). They’ve
posted an agenda
that covers fixing privacy issues that have come to the forefront in the last eight years. It involves repairing amendments that prevent corporations from being sued for warrantless wiretapping. They would also modernize the Electronic Communications Privacy Act so that it would cover modern technology. The heavily abused
State Secrets Privilege
needs reform as well. Their final issue is with
REAL ID
and datafarming that many state governments have already rejected. If even a bit of this gets fixed, we’ll be happy. In any case, it’ll be good to have a more tech focused administration that doesn’t need the internet explained to it in terms of dumptrucks and tubes.

The new doctrine wants to extend to the internet, as well. Many of you will take this as a joke but it is not. That means if ‘they’ have issue with anything you say or write on the internet, ‘they’ have the authority to ‘edit’ it or take it down altogether.That could make Hackaday a fun place… or maybe not. While Hackaday is mostly innocuous, I can assure you that many of the techniques that are discussed and linked to from this website would most likely be considered ethically sticky if/when the doctrine is enacted.It isn’t all about politics and I make no apologies for Bush as he has certainly done some things that would make anyone scratch their head and say WTF?!!!

[rocketman221] wrote up one of the simplest ways to
build a high voltage power supply
. This one in particular was used on his
coilgun
. Instead of building a custom circuit, he’s using flash charging boards from disposable cameras. Six 450V 470uF caps are wired in parallel to make up the bank. Two of the charger boards are wired to one switch to initiate the charging process. Four additional boards are wired two a second switch for the second charging stage. The part cost on this is incredibly cheap and it only requires a 3.3V input to reach 450V. The writeup has plenty of warnings about the dangers of high voltage; you need to clean off all flux residue to prevent arcing across the circuit boards. Embedded below is a video of the bank being discharged through several objects.

In the spirit of hacking, any of a hundred different kinds of metal or plastic cases could be used, salvaged from defunct appliances/electronics.Second– I didn’t see mention of bleeder resistors.Third — If discharging the caps while the charger boards are on will damage them, then you should probably rig the circuit so that this can’t occur. Use a SPDT or DPDT switch. Arrange it so that in one position, the cap bank is connected to the chargers, in the other position, the cap bank is connected to the output terminals. This makes the fault condition impossible to achieve.You will want a very robust switch with large points, otherwise you may end up spot welding the switch contacts together. Alternately, you could use a large relay/contactor to implement the same function. In fact, if you arrange the circuit so that the contactor is powered whenever the charger is on, then the switching function becomes essentially automatic.Fourth — I think this was mentioned…but if you want rapid discharge, you want to conduct the current out of the cap bank with bus bars, not with thin wires.",

[DJ Sures], who built the
autonomous Wall-E
, is back with another creation. His new
autonomous Cookie Monster
is certainly an interesting build. He had the cookie monster plush toy already so the first step was to flay the blue beast and insert a skeleton. He used another robot for that. There are two servos for the wheels plus one for each arm and one for the neck. There’s a distance sensor in the mouth. He built a custom board for the PIC18F4685 microcontroller which is running the same 2D mapping code as his previous bot. Check out the video of it in action below.

Not to be
outdone
, Popular Science published their
Best of What’s New 2008
and packed it with videos and photo galleries. Inspiring inventions include the
Pipistrel Taurus Electro
, the longest-flying two-seated electric plane, the
Intel Core 2 Duo Small Form Factor
, which you can thank for the thinner laptops like Apple’s
MacBook Air
, and the
GroundBot
, a spherical robot that can roll through the mud, sand, and snow. It’s not even the end of the year yet, but with all these great inventions, we can’t wait to see what’s in store for 2009.

Everyone always complains about the Christmas season coming earlier and earlier, but we think when we can have
Christmas trees like the one pictured above
, it’s not such a bad thing. Created by English fashion designer [Gareth Pugh], the tree features sixty white neon tubes, and is supported by a freestanding metal rod. It reminds us of the light sabers in Star Wars, which is probably why we like it so much. The tree is just a carrier for the decorations anyway, right? You can check out the tree in person at the TOPSHOP in Oxford Circus, London.

[war6763] sent us this
hack to power an amplifier in a MINI Cooper
. Apparently, aside from being unconventionally handsome, they’re also unconventionally wired. Amplifiers are generally wired to the ignition or stereo and turned on when the car is turned on. Due to some strange wiring, this just isn’t possible in the MINI Cooper. Some people use the cigarette lighter to power on their amplifier, but [war6763] wanted something that left his cigarette lighter free for other things. He built a circuit that monitors the cars built in USB input line and turns his amp on and off accordingly. The entire unit cost around $10.00. You can see the video demonstration after the break.

[Steffen Wernéry] has published a
video of the impressioning contest
at
LockCon
. We
learned about key impressioning
at this year’s
HOPE conference
. You start the process by inserting a key blank into the lock. By turning the lock until it stops and then moving the key up and down you create marks on the blank’s face. Take a file to those marks to remove the extra material and then repeat the process. Once the pins are set properly, they’ll stop leaving marks on the blank. It takes a lot of skill to do this right, but you end up with a perfectly functional key. [Barry Wels] managed to win the competition in 5:30 with second place coming in at 6 minutes.

Come on, folks. If we keep
tearing apart
everything that’s handed to us, we’ll never get nice things. SparkFun got their mitts on two
Kill A Watts
and proceeded to plug them into everything and then
dismantled them to see how they work
. The Kill A Watt keeps track of how much power is used over time. The largest load they found was their soda machine using 500W (should probably add a motion sensor to that). They plugged a meter on either side of a UPS and found out that it uses 5W just to charge. On the inside of the meter, there isn’t anything too substantial. One unlabeled IC runs the whole show.

WaldFlöte: Midi Controlled Pipe Organ

"midi",
"organ"

Members of Dorkbot Edinburgh have done what most of us would do if we had a 19th century pipe organ. They
hacked it to be midi controlled
. The organ is located above a cafe owned by the university of Edinburgh. Students have been repairing and modifying it to get it back in working order.
The electronics are composed of an Xilinx
Spartan-3E Starter Kit
as the brains and a
Microblaze
processor converting midi events for the solenoids. The cool thing is that none of this required any permanent modification to the organ itself. It can all be removed to put the organ back in normal playing condition. Check out the video after the break for some classical Van Halen.

We love all of the creative Halloween costumes that have started trickling in now that the holiday is finally over, and people have found time to document their last minute projects. Take this
functional Etch A Sketch costume
made by [mazinbenny]. The knobs are lawnmower wheels. The pulley system is strung with 1/16″ wire rope to move a carrier for a dry erase marker. The marker draws directly on an acrylic screen. HowStuffWorks has a post on
how a real aluminum powder based Etch A Sketch works
.
We’ve covered more technical Etch A Sketch projects in the past. We’ve seen them
hooked up to computer mice
,
drawing portraits at Maker Faire
, and commenters have even suggested turning
mechanical dry erase boards
into giant Etch A Sketches.

[Trixter], connoisseur of old hardware, is celebrating the 25th anniversary of the PCjr. IBM’s PCjr was killed only 18th months after being revealed and [Trixter]
lays out exactly why
. Overall, it was designed to be cheap to produce and sell, but many of the choices made it difficult to use. They used the CPU instead of DMA for floppy access; cheaper to make, but you couldn’t do much during disk reads because of it. The video memory scheme left little room for programs that could take advantage of it. It also had compatibility issues that made IBM clones a more attractive choice.

This looks like a great addition to your breadboard. [Nerdz] wanted a power supply that was easily portable and adjustable. He built a custom board that
plugs directly into the breadboard’s power rails
. It has a pot attached to the ground of a 7805 voltage regulator so the output can be adjusted from 5V to just under the supply voltage. Anything that makes a breadboard less of a rats nest is definitely a good thing.

In short, there is no strain relief.I’ve found a better solution is to connect the module to the breadboard with flexible wires. I’m fond of the gauge wire that you find in old Centronics printer cables (26 ga.?) For a little extra strain relief just tape the wires down to your table or whatever support platform you are using for your project.",

Evil Mad Scientist Laboratories has
updated
their
business card AVR breakout boards
to version 1.1. We suspect the changes will probably make them even more popular. The boards are designed for the ATmegaXX8 family of microcontrollers. The center has all 28 pins labeled while either end has a prototyping area. An
in-system programming
header is also provided. For the new version, both prototyping areas have been increased to accommodate DIP14 packages. The holes for the microcontroller are now larger so that they can hold a ZIF socket. Finally, the power and ground traces have been expanded. We’ve always like the versatility of these boards, as demonstrated in the
Tennis for Two project
, and can’t help wondering if these updates were made to facilitate another project.

When we posted about the
Drawdio release
, mentioned how simple the circuit was and that we wouldn’t be surprised if people adapted it. [Dylski] decided to
build it using stripboard
and parts he had laying around. He shows how he laid it out on paper so that it would fit on a 29×5 piece. It took some planning, but the end result is a perfectly functional as you can see in the video below.

SparkFun has
posted an excellent guide
to the many different issues you could run into when you finally decide to get a circuit board professionally produced. We assume that most of you aren’t running a professional design firm and will appreciate these tips gleaned from years of experience. They provided a rule list,
Eagle
DRC, and CAM file to help you get it right the first time. The end goal is designing a board that won’t be prone to manufacturing errors. The tutorial starts by covering trace width and spacing. They recommend avoiding anything less than 10mil traces with 10mil spacing. For planes, they increase the isolation to 12mil to avoid the planes pouring onto a trace. They also talk about annular rings, tenting, labeling, and generating the appropriate gerber and drill files. SparkFun isn’t completely infallible though, and manages to
produce a coaster
from time to time.
SparkFun naturally followed up this strict tutorial with a guide to
unorthodox header hole placement
. If you want to learn more about Eagle, have a look at [Ian]’s
overview of Eagle 5
and
Ruin & Wesen’s layout videos
.

It has nothing to do with the polygob plane.The limit’s they use are also totally out of date.Any normal PCB manufacturer accept 0.5mm track/spacing (even for polys) and 0.2mm holes without a problem, these days. And that’s without additional costs.If _your_ manufacturer cant, find another.If your boards are produced by a ultra low-cost, low quality manufacturer like Olimex, you have only yourself to blame.",

[bunnie] managed to pick up a
Nintendo DSi
while in Japan. It seems he had the device running less than an hour before he
tore it down for an impromptu hotel photoshoot
. There’s nothing too surprising and he mentions that the CPU certainly feels more capable than the previous model, which may explain the shorter battery life. The ARM processor sits under an RF shield directly below the
WiFi
card. The best photo is the top side of the board with every single debug point labeled in plain English on the silkscreen. We’re sure that’ll help with the development of
new homebrew hardware
.
[bunnie] has posted some interesting teardowns in the past. Have a look at his
Sony XEL-1 teardown
to see the inner workings of an OLED TV.

[Johnny Lee]’s colleague [Paul Dietz] has done some interesting work using interactive tables. He’s specifically researched
how to determine how full a drink glass is
. In the video above, he’s using
Microsoft’s Surface
, but this technique should work with any IR camera based multitouch table. Determining the drink level requires custom glassware that has a small prism inside. When the liquid level is above the prism, light passes through, but when it’s below the top it reflects more IR light back into the table. Using this information, restaurant staff could serve drinks in a more efficient manner.
[Paul] has worked on another project that uses
RFID and capacitive sensing
to a similar effect.

CatGenie Hacking

"catgenie",
"litterbox"
] |
[ScottSEA] has six cats. As you can imagine, with six cats, a simple litter box just doesn’t cut it. [ScottSEA] uses the
CatGenie
. While a self cleaning cat toilet is a technical marvel, it has one major drawback. Much like an ink jet printer, it has disposable cartridges. Those cartridges, just ike some print cartridges, have a built in counter that disables them after so many uses. After adding up the totals for six cats worth of cartridge use, [ScottSEA] started hacking. He has posted directions on how to
manually refill them
, as well as
reset the internal counter
using an
Arduino
.
We suggest that he find a way to harness all that cat power for his home electronics. How many watts could you produce per cat?

Looking at the arduino code he posted on instructables, it has the eeprom address hardcoded, and he sends two bytes of data to it.Actually, I tend to like his idea of setting up an microcontroller to continuously report a cartridge as full as the better idea, instead of resetting each cartridge when it empties. It makes the need for a microcontroller realistic. Otherwise, what he is doing, rewriting an standard 24xCxx eeprom can be done directly from his computer with a minimal amount of parts (Serial port, two diodes, four wires, plus programming software, free). No need for a 35 dollar microcontroller.",

Simple eeprom-based countdown. Only bytes 4,5,6 (Starting from 1) matter. And I made a mistake, his code actually sends all 16 bytes to the eeprom, not just 2. His code can be cut down if he just overwrites bytes 4, 5 and 6 instead of all 16. But its damn minor.",

In the instructiuons you say “Slide the cartridge into the holder. The LED will illuminate almost immediately – reset was successful. Slide the cartridge out, and in a couple of seconds the light will go out – its ready to reset another one.” I haven’t yet reset a cartridge. Ok when I download the program and reset the board the LED stays on and never goes out. I would assume that since the LED will go on almost immediately that means the LED is suppose to be off and will turn off after the cartridge is removed and be ready to reset another cartridge. Looking at the sketch I see where Resetsucess is set to false then resetsucess = verifyCartridge(). The only thing I can think is since I have not reset a cartridge yet, verifyCartidge()is somehow set High changing the state of resetSucess, or is set high because there is no cartridge to hold either pin 4 or 5 low when the program starts. The program apears to be working correctly only problem is I don’t have a spent cartridge to reset yet so I wont know for 15 days or so if the Arduino protyping board is working correctly.",

Although they describe how the cat genie is suppose to work as with most patents the drawings are all first concept drawings and the electrical schematics although close to what the cat genie was eventually released as are not exact and they leave out certain aspects like the sanisolution cartridge. It is mentioned but the circuitry on the cartridge is never shown, it sounds like the method they originally wanted to use to detect the soloution level was different from what they wound up actually doing. I think they discovered if they did it with some sort of level sensor (which is how they describe it) all the user would have to do is refill the cartridge. I also found another way to reset the cartridge by buying a EEprom programmer for the 24LC00 EEprom they are using on the cartridge. What you do first is connect up the 4 wires used on the programmer needed to communicate with the EEprom to a new/full cartridge, read the memory which will give you a series of 3C which is 60 hex save that data. Then once a cartridge is disabled just connect up to it in the same manner and write the full data you read and saved from the full cartridge to the EEprom. Wha-la cartridge reset. Requires a computer to do it though.",

Acidmods Custom FPS Controller

"acidmods",
"controller",

"gamepad",
"xbox"

Yet another
custom X Box controller
has come out of the acidmods foundry. This one, specialized for FPS games opts for two analog sticks up front, and complete removal of the D pad and buttons. They break down the process quite nicely with very detailed pictures of how to modify the case and move the analog stick. Check out the video of it in action after the break.
[youtube=http://www.youtube.com/watch?v=5VALa_jlQ8o]
As you may recall, this isn’t the first
FPS specific controller mod
we’ve seen from them.
[thanks Mark]

One of the (many) problems I have with console FPSes is the need to sacrifice your aiming thumb whenever you want to press an X/Y/B/A button.",

[Olivier] told us about this fantastic project where he
built his own RC airplane
. The airplane itself is nothing special, it is the controls that are worth paying attention to. He used an Arduino Diecemilla , some XBee transceivers, and a SparkFun Wee. The main site is a general overview, but there are links to more detailed breakdowns of how to build some of the parts. There are several videos of him flying it as well.

What is needed is a way of recognising the deviation in its very early stages. The sensor(s) will have to be onboard the craft. The sensor will have to ‘see’ the aircraft’s responses to the change in the control surfaces’ positions.How to integrate the control signals with the disturbance signals? Electro mechanical, use the RC RX to move servos that position the platform the disturbance sensore are on. Therefore, in roll, they bank the platform to port, the roll sensor sees the movement as a disturbance and bank the aircraft to starboard to compensate. Any other erratic or irregular disturbance is dealt with automatically.This potential solution will not suit purists who might insist on a wholly electronic/software solution to the problem. It is the solution used commercially for decades on full size aircraft.",

Mcor Technologies recently launched a brand new rapid prototyping machine. The
Mcor Matrix
forgoes the standard of expensive and rare build materials by using A4 office paper. The machine selectively deposits glue on the sheet of paper: more glue on the cross-section, less on the waste. It then uses a blade to cut out the part profile. The vertical resolution is determined by the paper thickness. You can use either 20lb paper, which has a thickness of .1mm, or 40lb, which is twice as thick, so it will build twice as fast. The final part can be sanded and painted like wood. The idea is similar to
LOM
, but those machines require specialized paper. It’s nice to see a company intentionally target a low cost of ownership. If they had used a laser though, you’d only have to worry about sourcing the glue. Machine and material prices have yet to be announced.

I have the servos and controllers from a few old scanners and some industrial paper feed mechanisms from the tons of printers I got from work! Now all I need is an Arduino, a high powered red laser (I bought the 720nm lasers for my Multi-Touch table from aixiz.com and they were awesome!) and some Angle Iron for a frame!Right after I finish my Multi-Touch Table! :D",

Arduino has just released an
official ethernet shield
. It’s based on the same WizNet W5100 chip that was used in the
tiny ethernet board
we covered earlier. The W5100 handles the full IP stack and can do TCP or UDP with four simultaneous sockets. The board has a power indicator plus six LEDs to debug the connection. It works with the standard
ethernet library
. The reset button resets the shield and the Arduino. The SD adapter is not currently supported by the
Arduino software
.

Design Robots To Hunt Humans

The
Department of Defense wants you to design a pack of robots
that would hunt humans. Or, as they put it, “search for and detect a non-cooperative human subject”. While the project brings to mind Terminators, there are also non-terrifying uses for these robots, including search and rescue missions. The robots should be about 100 kilograms or less, provide immediate feedback, and defer to a human operator in the event of a difficult decision. This project presents some interesting challenges for robot designers. They’ll need to consider several key issues, like robot cooperation and decision-making abilities. We knew it was only a matter of time before the DoD turned the
Grand Challenge
into
Death Race
.

[Aaron Nelson] of
Hijinks Inc.
wrote up how
he installed OSX on his HP TouchSmart IQ507
. It looks and works like you would expect, save for a few things. The touchscreen works, but the calibration is so far off it’s useless. The most important things, like ethernet and the memory card reader, work fine. [Nelson]’s biggest frustration is that he has to disable the on board audio every time he logs in, so that the keyboard and mouse will be recognized. He is working on improvements, and would love to hear any suggestions you have.

Instead of the normal head in a window or split screen display used when interviewing remote guests, [Wolf Blitzer] will be
interviewing 3d holograms
. Supposedly, they will be recording in a way that allows for 360 views to be projected on stage with [Wolf]. We’ll have to wait and see exactly how they plan to pull that off, but our suspicion is that it will be similar to the Gorillaz live performances. Join us after the break to watch one.

I hope we don’t lose it, then we’d be in biiiig trouble!”If they had just not said anything about it, and let the effect just be an effect, it wouldn’t be too bad, but listening to him try to sell it when its obviously not real is just lame.-Taylor",

Demo videos online already look better than what CNN came up with.I suppose the problem was that they were feeding all of the video input from offsite back to HQ to render the angles, which is a terrible waste of bandwidth IMHO.It likely would have worked much batter if they shot from waist up and placed the virtual actor behind a desk with a single angle. Obviously, still utilizing the imagination of the actor sitting next to them, but they could be looking at an off-set screen like weather folks usually do.",

[Eric] has put together a simple python script to
scrape election results from CNN.com
. It uses urllib2 to return the popular and electoral votes for each party and throws an ElectionWon exception when CNN calls the race. He’s planning on hooking this to DMX controlled RGB LED lighting that will shift to either blue or red as the night progresses. It’s a great starting point if you want to pull off something similar.
You may remember [Eric] for building the
IKEA MAME table
and the
TRS-80 wireless terminal
.

UPDATE:
[Garrett] of macetech is
putting the finishing touches on his version
which uses 32
ShiftBrite
modules and 2 4-digit displays controlled by a
CuBLOC
.

Inductive Charging Going Mainstream

"wireless charging"

The recent
announcement of Psyclone’s TouchCharge kit
has us moderately excited. Though inductive charging has been used in
electric toothbrushes
for ages, we have yet to see it infiltrate the rest of our lives. The kit is a bit pricey at the moment, but it is a step in the right direction. Unfortunately, you have to have an adapter for your specific product and their selection is pretty limited right now. Why not
make your own
to power your devices? Warning: it is written from the perspective of [Arnold Schwarzanegger].
Update: Is the TouchCharge kit inductive? It appears to require contacts to touch the base.

(when not using the controller you need to put it somewhere anyway, so why not have a plug-in spot for them? Is it really any harder than laying them on a “charge pad”)",

AcidMods is at it again. They just can’t bare having to push the fire button over and over on their own. They’ve made a
rapid fire mod for the wii
. They said the mod wasn’t too difficult as Nintendo labeled everything nicely on the PCB. We like that they have added the back light on the button to tell you that you’re in rapid fire mode.
[Thanks Mark]

Wooden Retro Keyboard Build

[phirzcol] sent us this cool step by
step build of a retro looking keyboard
, Inspired by [Von Slatt] and
his work
. [phirzcol] starts with a standard keyboard and removes the keys. He steams some wood to wrap the keyboard, then finishes it off nicely. The process of making the keys looks pretty grueling. Each key has 4 parts which have to be hand cut and assembled. A blue accent light is a nice touch as well. The keyboard looks pretty good, but we’d like to try typing on it for a while to see how usable it is. If it looks like too much effort, you can actually
buy it on ebay
.

Meet Skelly, the propeller powered singing skeleton, winning entry to the
Unofficial Propeller Halloween Contest
. Sick of the massive amounts of Arduino projects floating around the web, [Oldbitcollector] offered a halloween challenge. Make something spooky using a
propeller and other parallax stuff
, win a prize. Skelly, made by [Chuck Rice] was the star of the show, so [Chuck] will be getting some USB development boards in the mail.

But the nice thing about using the propeller is that I can keep half a dozen of the propeller boards on hand and slap them intouse quickly for a project. Most of the software is in available as “canned routines” and I can just select the ones I need, add a few components, and go. Next thing I want to add is a scanning range finder, so that the skull can be positioned to look back and forth between the two roe three closest bodies. I then want to add code to trigger on specific frequencies. The jaw does this with a black box at the moment, but I am not happy with the volcal triggering. So, I plan to allocate a cog and some additional hardware to trigger the jaw motor. Then I can allocate a third cog to listen for a different frequency and cause the hand to strum the guitar. A fourth cog and listen for the base beat and tap a foot. I have coded for PICs and AVRs and BS2 and others. For me, the spin/propeller combination just work out better for the things I like to do.",

The latest version of the
Nintendo DS
, the
DSi
, has officially launched in Japan. It features larger dual touchscreens, dual cameras, and an SD card slot. The members of GBAtemp.net have decided to tackle the most important question:
will it run homebrew
? Current DS systems just need a purpose built flash cartridge to load homebrew software (usually stored on MicroSD). Forum members have tested at least 10 different flash carts, and
none of them worked
. While not completely exhaustive it’s proof enough to us that current generation carts will not work. We hope this is something that can patched with a new firmware. Most carts load their firmware off the flash, so upgrades are easy. The blocking of homebrew maybe a side-effect of Nintendo’s announced
region-locking on the DSi
.
We hope this gets sorted out soon. Maybe we’ll see hackers figure out how to take advantage of the SD slot instead. If you’ve got a Nintendo DS, there’s no excuse not to be playing with homebrew. It’s as easy as copying files to a card. We’ve had success with the DSTT, which you can
find on DealExtreme for just $10
.

But once you do this, it violates the contract with Nintendo and YOU WILL NOT BE ABLE TO UPDATE YOUR SYSTEM. But assuming they sniff your system for any programs to tamper with the script, you would just do it when they update your system. It is logical that to download something, you have to allow it in. That is what Nintendo is doing, they are allowing people in to update the system. So they may just leave the doors open and WALLA!! New script, homebrew working, and your good to go.",

[Eric] sent in this cool project that he did as part of his graduation project. He built
a game that uses a gyroscope as an input device
. For the gyroscope, he’s using a
Powerball
with a sensor inserted into it. This data is gathered by an Arduino in a pretty enclosure. The whole unit connects to a PC
via
USB
and is supposedly plug and play. There’s a video of the setup in action on the site, just try not to laugh too hard watching them.

Our
flickering LED circuit
combined two known circuit, and certainly wasn’t graceful because of it. [sprite_tm] saw quite a few areas
where the circuit could be reduced
. He ended up taking it down to just two LEDs, a battery, and an ATtiny13. The first step was getting rid of the current limiting resistors. The datasheet shows that with a 3V supply the AVR will limit the current well below the maximum current. The light sensor was removed next. [sprite_tm] referenced an earlier post on
sensing with LEDs
. He measures the voltage across one of the LEDs while it is off to see how much light is hitting it. The current draw while on is 10mA and 50uA while off.

If you’ve been holding off on a
T-Mobile G1
purchase because you didn’t like the apparent user restrictions, there’s some good news. The
Android
powered phone comes with an easy button for getting root. Install a terminal app and you can
manually start the telnetd service
. All that’s left is telenetting into the device and it’ll give you root level access.

[youtube=http://www.youtube.com/watch?v=7QMV4mRVpo4]
got an old cdrom and an Arduino laying around? Why not make it into a
spinning POV display
. It was built using parts from a floppy drive and a cdrom, as well as an Arduino and a small wireless transceiver. Using an IR sensor to detect rotations, the Arduino sends data to the LEDs. The wireless is used when sending new messages to the device. The link is in Spanish, so here’s the
Google Translation
.

LCD That Scans Fingerprints

"uv"
] |
AU Optronics Corp has unveiled a new
LCD panel that doubles as a fingerprint scanner
. Each pixel is equipped with 4 optical sensors, so a 320×240 screen would have a scanning resolution of 640×480. They have also experimented with different sensors, such as UV. You can see an LCD panel that detects and displays the UV index above. Why did they use a secondary display to show the data though?

It seems like there is a pre requisite that any technology demo should include pong. It may not be new tech, but we’ve
never seen pong played like this
. It seems like it could get pretty hectic if it were to be sped up.

Though we’re pretty sure this was meant for Halloween, we think it would be a perfect addition to your election night party. [marc92] shows us how he built a
fog spreader with red or blue lighting
. Fog machines generally spit out the fog from a single point, relying on the breeze to spread it around. [marc92] wanted it spread a little more evenly, as well as some nice mood lighting. He built a pipe system that would emit fog from a much larger area. Mounted on the pipe are red and blue LEDs. Mix this with some of the
election lighting systems
and you’re set for a party. We know this is an extremely simple project, so it should give you plenty of time to get out and vote before the polls close.

"content": "standard fog fluid or “fog juice” is usually just water and food-grade glycol. gross, but safe.Generally, when you pump fog through a tube or hose, you want to have some area in front of the nozzle where the water-glycol mix can properly aerosolize. This will let more of the fluid stay in the air. I’ve seen some projects that use a sealed bucket or plastic storage bin, with an outlet for the pipe.It is also usually a good idea to have an “air accelerator” to push the air along the tube. however, if you draw the fog through a fan you will get fluid gumming up on the fan. it may be best to mount a fan blowing into a large bin, with the fogger inside, and a hose or pipe coming out.Many professional foggers also use water glycol, but lots of plumbed fog systems will be cryogenic fog systems using co2 or liquid synthetic air. Mineral oil foggers seem to be less popular, but they can still be found.Smoke machines are generally considered unhealthy, and are not used anymore. (smoke is solid particulate where fog is liquid.)",

November 1st means that registration for
ShmooCon 2009
has opened. The DC hacker convention is entering the fifth year. They’re releasing the tickets in blocks; after today’s are gone the next won’t be available till December 1st. Today is also the closing of first round consideration for their call for papers, but you still have another month before the final deadline.
We’ve always enjoyed our time at ShmooCon. In 2008 we saw talks on
cracking GSM encryption
and
recovering data from SSDs
.

It can sometimes be difficult to decide what items we want to fill space in our homes. Our health is valued highly, as is our ability to consume cold beer. Someone out there must have been thinking of us when they designed this
exersize bike that chills your beer
. Admittedly, it won’t chill it as fast as some other methods
we’ve tried
. We also may end up forcing our friends and loved ones to do the actual chilling, but beer tastes better when cooled by slave labor anyway.

Promises, promises, promises. The
$200 Eee PC is supposedly coming in 2009
, according to chairman Johnny Shih. No word on whether it will be a 10 inch screen, but it seems possible as they have stated they are phasing out the smaller models. Other interesting facts were divulged, such as 70% of them are now loaded with Windows XP and hard drives.

The Hex Bug, at $10, proves to be
a perfect platform for building your own droid
. Out of the box, it has pretty limited functionality. It walks forward until its antennae bump something, then it backs up and turns left. Applied inspirations shows us how you can replace the bug’s brains with a microcontroller to give it much more life. Instead of hacking into the existing electronics, they chose to completely replace the board. The final result, though still only able to turn one direction, is much more robust. They discuss the ability to add numerous sensors as well as pre program different behaviours and personalities.

Now that we listen to
MP3s
, and watch XVIDs or x264s, a computer is the entertainment center in at least one room of most homes. Unless you have a special HTPC, though, you’re probably stuck using the keyboard to pause, change the volume, and fast-forward through annoying Mythbusters recaps. PC remote control receivers range from ancient serial port designs (who has one?) to USB devices not supported by popular software. In this how-to we design a USB infrared receiver that imitates a common protocol supported by software for Windows, Linux, and
Mac
. We’ve got a full guide to the protocol plus schematics and a parts list.
Design overview
Remote controls transmit data on an modulated infrared beam. An infrared receiver IC separates the modulated beam into a clean stream of 0s and 1s. The data stream is decoded by a microcontroller and sent to a computer over a USB connection. Software processes the codes and triggers actions on the computer.
Background
Computer infrared receivers
The
oldest PC infrared receiver design
uses a receiver IC to toggle a serial port pin, usually DCD. This design probably originated on
Usenet
, and it’s still the most popular on the web:
Engadget
,
Instructables
, etc. These aren’t true serial devices because they don’t send data to the PC. Instead, a computer program times pulses on the serial port and demodulates the signal. This is a super simple design, but it depends on direct interrupt access and timing precision that’s no longer available in Windows. Linux or Mac users can try this receiver, if you still have a serial port. We couldn’t get this type of receiver to work with the serial port on a modern Windows XP PC, and don’t expect the precise timing to transfer through a USB->serial converter.
Some more advanced infrared receivers are true serial port devices that measure or decoding infrared signals before sending data to the computer. The
UIR/IRMan
and
UIR2
incorporate a classic PIC 16F84, but don’t provide firmware and/or source code. These devices should work on a modern computer, through a USB->serial converter if necessary. The
USBTINY
and
USBIRBOY
are native USB devices, but lack wide support.
Receiver software
Regardless of receiver type, the computer needs a program to listen for incoming remote commands and convert them to actions on the computer. Linux and Mac users have
LIRC
, which supports a bunch of different receiver types. Windows users are a bit less fortunate.
WinLIRC
is an abandoned Windows port of LIRC for simple interrupt-based serial port receivers; WinLIRC was last developed in 2003.
Girder
was originally a freeware PC automation utility, but has become expensive bloatware with a 30 day trial. Fortunately, the last
freeware version of Girder (3.2.9b)
is still available for download.
Working with IR remote protocols
Decoding IR signals
Remote controls encode commands in the spacing or timing of a 38KHz carrier pulse, [San Bergmans] has an
explanation of the principals involved
. An infrared receiver IC separates the data stream from the carrier. Our job is to decode the data stream with a microcontroller. There are dozens of remote control protocols, but Phillips’
RC5
is widespread and commonly used by hobbyists.
RC5 is stream of 14 equal length bits of exactly 1.778ms per bit time. A pulse during the first half of the bit time represents 0, a pulse in the second half represents 1. This scheme is called
Manchester coding
.
We used a logic analyzer to examine the output of a Happauge WinTV remote control, a
known
RC5 remote. The diagram shows two presses of the 1 button, and two presses of the 2 button; note that the output is inversed and the Manchester coding is backwards from the above description.
The first two bit times are start bits, followed by a toggle bit. The toggle bit inverses each time a button is pressed so the receiver can tell the difference between a hold and a repeated press. The next 5 bits are the address (0b11110=0x1E), followed by the command (0b000001=0x01, 0b000010=0x02). A backwards compatible extension to RC5 uses the second start bit as command bit 7.
Representing remote codes to the computer
Looking at previous designs, we saw three general methods of communicating remote commands to a computer:
Protocol specific receivers decode one protocol, and send actual decoded commands to the PC
A more general type of receiver measures the timing and spacing of each pulse and sends the full waveform to the PC for analysis.
Some receivers create a unique hash for a signal, but don’t actually include enough data to fully recreate the waveform.
While our preference is towards the general hash method, our only remote uses RC5 and it was more interesting to build an RC5 specific decoder. We describe modifications for a more general version in the firmware section.
Computer interface protocol
We didn’t want to write our own receiver software or driver, so we looked for an existing, well established communication protocol to imitate. The UIR/IRMAN/IRA/CTInfra/Hollywood+ type receiver is supported by Girder and LIRC, and uses a
simple serial protocol with handshake
:
The device is initialized by the DTS and DTR pins of the serial port. We don’t have these and don’t care.
The computer sends “IR”, with an optional delay. The device replies “OK”. We’ll just send “OK” on every “R”
Remote control codes are sent as a unique six byte hash. We’ll decode an RC5 signal and send the actual values, but a generic hash could be used instead.
This protocol is for a serial port device, but our USB receiver will appear as a virtual serial port and the program won’t know the difference.
Hardware
Click here for a full size schematic
(png). Our receiver is based on a USB enabled PIC
18F2455
microcontroller, the smaller, cheaper version of the 18F2550. The 18F family is programmable with the hobbyist favorite
JDM-style programmers
if
a diode is used
to drop VPP to a safe level. The PIC gets one decoupling capacitor (C1), and a diode (D1) and resistor(R1) on the
ICSP programming header
. We exposed the serial port on a pin header for debugging or a mixed USB/serial port version using a
MAX RS232 transceiver
IC.
The USB peripheral requires a 20MHz external clock (Q1, C5,6), and a .220uF capacitor. We faked the capacitor using 2 x .1uF decoupling capacitors (C2,3). A 3mm LED (LED1) and a 330ohm current limiting resistor (R2) show USB connection status.
We used a TSOP-1738 infrared receiver IC which calls for a 4.7uF decoupling capacitor (C4). If you can’t find this particular IC,
any receiver listed here
should work. The TSOP-1738 output is the inverse of the received signal, it pulls to ground when a pulse is detected, so a pull-up resistor (R3) holds the pin high when no signal is present. Check if you use a different receiver, you may need to use a pull-down resistor and reverse the Manchester decoding routine in the firmware.
The circuit draws power from the USB bus, so we don’t need an additional power supply.

Firmware
The firmware is written in C using Microchip’s free demonstration
C18 compiler
. Firmware and source are included in the
project archive
(zip).
We used
version 2.3 of Microchip’s USB stack
to create a USB serial port using the default drivers already available on most systems. The USB stack has simple functions to enumerate the USB device and transfer data between device and host. It only took a few pin changes to get the CDC demonstration working on our custom hardware.
Our implementation of the UIR/IRMAN/IRA/CTInfra/Hollywood+ protocol simply responds to the letter ‘R’ with ‘OK’. This should satisfy the handshake requirements of any implementation of this protocol.
We chose to specifically decode RC5 (and RC5x) because it’s a widely used protocol, and the only type of remote we have to work with. Most of the decoding is done in the interrupt handler:
The first signal change triggers an interrupt that starts a 889us (one-half bit period) timer.
On each timer interrupt, one-half of a Manchester coded bit is sampled.
Every other interrupt the measurements are compared, and the bit value is calculated to be 0, 1, or an error. Errors reset the decoding routing.
At the end of each transmission the address and command bytes are decoded, and sent to the host with 4 buffer bytes(0). We discard the toggle bit because it would confuse the PC software into thinking every other press was a unique code. We append the second start bit to the command bit for RC5x compliance; this just adds 0x40 to non RC5x remote codes.
A more general version can be made by removing the Manchester coding step (3), and sending 48 sample bits (all 6 bytes) to the computer.
Installing the USB infrared receiver
Most operating systems already have drivers that support a virtual serial port device like the receiver. Windows XP has the required drivers, but needs help from an .inf file to properly associate them with our device.
Windows will show the new hardware dialog the first time you plug in the receiver. Choose to use a custom driver and point it to the .inf file included in the
project archive
(zip). This links the device to a driver already included in Windows, and adds the receiver as a COM port. You can check the COM port number in the control panel.
Mac and Linux users can use the receiver with LIRC, but Windows users will be faced with the choice of the old, freeware Girder, or the new, 30-day trial shareware version. We used the freeware version of Girder, but hope you guys can suggest a great, open source alternative that we overlooked.
Regardless of the computer-side control software you use, configure it for a UIR/IRMAN/IRA/CTInfra/Hollywood+ style receiver, and enter the COM port or serial address assigned to it. Our receiver is also compatible with any protocol options like ‘Fast UIR Init’ and ‘Skip UIR Init Check’, which shorten or eliminate the “IR”->”OK” handshake. Now test the receiver and add a remote according to the documentation for your software.
Manual terminal interface and debugging
If you have a problem with the receiver, or you’re just curious, try to interface it from a serial terminal. We really like the serial terminal on
Hercules
. Set the correct COM port, but the speed and configuration settings are ignored by the USB serial port driver.
A capital ‘R’ will prompt the receiver to reply ‘OK’. RC5 codes are returned as raw bytes, so be sure to set your terminal to show HEX values rather than interpret it as
ASCII
text. The first byte is the RC5 address byte (0x1E), followed by the command byte (0x41), and then four buffer 0s to comply with the UIR/IRman protocol. The image shows the handshake, and the output of a short press on the 1,2, and 3 buttons.
A free utility called
Portmon
logs COM port activity for review. This is helpful for spying on existing receiver protocols, and debugging the interaction of our custom hardware and closed/proprietary software. The image shows Girder sending the initialization string ‘IR’ (0x49,0x52), and the receiver reply ‘OK’ (0x4F,0x4B).
Taking it further
Our RC5x compliant receiver follows a widely used interface protocol. There’s a ton of possibilities for additional features in an open source infrared receiver:
Support all remotes through a generic hash generator, like the original UIR/IRman hardware.
Add additional remote protocol decoders, like
RC6
.
Support multiple, configurable interface protocols.
Implement the serial port I/O.
Store configuration options in EEPROM, including protocol, interface mode, timing options, serial port, etc.

"content": "So the old irman simple Ir reciever will not work with XP? they also dont work with USB-RS232 adapters?I better tell the two systems I have working they dont work… Dammit I hate it when hack a day tells my stuff it’s not supposed to work.Note: if the article writer KNEW anything about IR and RS232 he would know that the statements about it not working under windows or with a USB/Rs232 adapter are silly. IR transmits at a data rate that is FAR slower than the faster Rs232 rates so it’s easy to lazily decode it in software.Now install Vista on a Pentium 2 400mhz machine and then you’ll have problems. But any modern machine has plenty of processing time and power to catch the incredibly slow IR signal. 40khz is the carrier NOT THE DATA, and if you use one of the IR reciever parts instead of a photo transistor you can easily decode it under vista in spare time over a usb rs232 adapter.Most of the time the little IR recievers are easier to find than a phototransistor, and solve all your problems with filtering and signal conditioning. I can simply toggle the RX line and set the computer to 2400 baud and capture ALL The data coming in without effort.Neat-o pic project, but don’t start the article with lots of FUD about the process.",

You can remove the Manchester decoding code from the interrupt routine for a more generalized ‘hash’ of the remote control protocol.If you are having problems, first make sure that interrupts are triggering by lighting the LED on the first interrupt of the tsop.If you’re getting an interrupt from the TSOP, but no remote control codes, then it’s probably that your remote does not follow the RC5 protocol. Remove the Manchester decoding routine and just spit the raw sample out the virtual serial port into a terminal to verify. Now do a fit of fu to get a 6 byte hash and you’re done.",

Here’s a video of a mindbending piece of papercraft engineering. We’d love to see a 3D model for this heart to at least have a starting point when designing our own. The
creator’s site
is in Japanese though, so it’s hard to glean any insight into his process. Embedded below is a similar cube version.

Once you set up the group of gears, you could probable carve it to any shape you wished.The bottom gear is probable freely turning on a hollow shaft, with a central axle driving the top gear which in turn, drives all the others. Like the bottom gear, the other driven gears are mounted to the fixed hollow shaft.Take a look at ‘bevel gears’ on wikipedia, and you should be able to figure out how it’s done from the diagrams.",

[tnkgrl] is back with
part three of her Acer Aspire One hacking
. This time she’s adding in 3G. You may look at the picture the above and think, “Cake. She just plugged the card in”. No, the Acer doesn’t ship with the mini-PCIe slot or the SIM card holder. First you have to solder a right angle mini-PCIe connector to the board pads and bridge two others to provide power. The SIM holder was another problem. She wasn’t able to find a pin compatible one. The one she installed is mounted to a riser so she could change the wiring order (let her know if you can find the correct part). This mod definitely requires some good soldering skills and she warns that even she managed to destroy a SIM in the process.
The Dell Mini 9 is another netbook that doesn’t have the appropriate connectors soldered on board, but
JKK has a work-around
. You need a 3G modem that has the SIM card on board. You plug it into the WiFi slot after taping over a few pins and then use a USB WiFi card instead.

For roughly $250, you too can have this
sweet bit of gadgetry
based off of the
Arduino platform
. It is open source, and has some pretty impressive specs. Sporting a rumble pack, lithium ion battery,
OLED
display, and space for expanson. You can buy the pieces pre assembled, or as a kit. If you get the kit, you’ll see that the controller board has been laid out so that you can solder your buttons and joystick in as either left handed or right handed. The only problem? No games yet.

Autonomous Wall-E

[djsures] went crazy on his
Interactive Wall-E toy
. Wall-E just didn’t have enough bounce in his step, so [djsures] decided to give him an overhaul. He went through the entire robot and replaced most of the joints with servos, giving much more control and adding head tilt. All of this was wired to a microcontroller housed in Wall-E’s body. The distance sensor was mounted in Wall-E’s neck, so when he turns his head, he’s actually surveying his surroundings. Check out the video after the break.
[youtube=http://www.youtube.com/watch?v=mdV3zfvbF5Q]
There’s lots of great info in this instructable, from specifics on how he did certain parts to links about how servos and microcontrollers work. Great job [djsures].

The
AM300 developer’s kit
, shown in this video, has some pretty cool new features. It has the ability to show much faster animations than before, as well as having 16 bit gray scale image rendering and pen input. The animations look pretty quick, they mention this being useful for diagrams and advertisements. We just can’t wait to have our newspaper look like its covered with annoying flash banners and animated gifs.

Blinkomat, an LED matrix
, turned out quite well. 240 LEDs controlled by an Atmega 16 is what we call a decent bookshelf decoration. The dimensions of 12×20 were chosen due to the fact that the microcontroller has 32 I/O lines. The LEDs are switched on and off using
multiplexing
. The brightness, controlled by pulse width modulation can be varied by 16 levels. The overall effect is quite smooth an fun to look at. He has programmed it to do other things than just cellular automata. Our personal favorite is a simple sine wave. Watch it after the break.

Last week, we covered a smaller, but equally cool
automata simulator using charlieplexing
.

Here’s a fun little suprise that showed up in a recent Flaming Lips interview. Frontman Wayne Coyne built this custom guitar rig out of a double-necked Epiphone. It has a neck from a Guitar Hero controller, which triggers a built in KORG
Kaossilator
touchpad synthesizer. Checkout the
video interview at around 1:55 for a demo
. He went with the Guitar Hero controller because he feels that it’s replacing regular guitars in childrens’ perception of how guitar is played.

[alien x] has posted this
peculiar hack for a PSP
. He has gutted and splayed the
PSP
spreading its insides neatly and mounting them on a plexiglass back. Everything is easily accessible and ready to tinker with. It may not fit in your pocket, but adding mods and experimenting with ideas should be much easier like this. It looks pretty cool too, we want one for our office wall. That could be possible too, he’s selling it.
[thanks doodle]

T-Mobile’s G1
was released last week and there has been
at least one Android vulnerability announced already
. The New York Times reported on research done by [Charlie Miller], who also helped find one of the first
iPhone
bugs, so we think the report is fairly credible. Last year, we saw him deliver a
seminar on real world fuzzing
at ToorCon 9. It covered exactly how they found the iPhone bug.
If you just want to use a G1 without service, you can
activate it with any T-Mobile SIM card
.
Above is Boing Boing Gadgets’ concise
video review of Griffin AirCurve
. It’s garbage. We first talked about it in our
loaded horn post
because it looked like something fun to redesign.
The iphone-dev team published a video today showing
access to the iPhone’s baseband processor
. They connect to the device over ssh and then use minicom to issue AT commands. They’re writing custom AT commands for full control.

With the
release of the Arduino Duemilanove
, Adafruit is trying to shift out some old stock Arduino Diecimila by
offering 10% off
. [amk]
noted
that the new Duemilanove is not so much an upgrade as an Arduino with a new hat. The only changes were autoselecting power and a cutable reset line. The best part about the Adafruit sale is they’re offering Atmega328s preloaded with the Arduino bootloader as a $5 upgrade. The Atmega328 gives you twice the flash memory, twice the RAM, and twice the EEPROM than the original Atmega168.

The “level shifter” can be scavenged from a cellphone data cable and shared across all projects, as it is built into the RS-232 cable end. The power can be determined per project, I like to use 4x NiMH for ~5v, thus making the circuit cheaper and simpler.The whole point of the arduino is to shield new users from circuits and pinouts and level shifters and programmers. To some extent this includes shielding them from soldering if they don’t want to, so a kit is not the best choice for some if they are already considering an Arduino over a bare Atmega and Crystal at around $5-7",

pointed out
a couple incredibly small optical theremins that look like they’d make for a great afternoon project. [AlexArt]
first built the simple circuit
on a piece of protoboard (Google translated). Knowing he could go smaller, he then
built it freeform with a buzzer
instead of a full size speaker. The design is based around the common 555 chip and photoresistor.
Here’s a simple circuit
you can use to lay out your own. The optical theremin should not be confused with the traditional RF theremin since the name comes from the similar sound, not similar construction.

There is also the touchless volume control on a Theremin through a similar setup, and that isn’t even attempted to be emulated.Again, cool synth/noisemaker/whatever. Not a Theremin though. Might as well just call it a guitar or a cell phone. They all make noise so they are the same thing, right?",

Wow, how quickly the wearable electronics world has slid into the gutter. They’re now resigned to watching our nations finest natural resource, the butt crack. This project by [semiotech] uses a
LilyPad Arduino
to
monitor the exposure of the wearer’s coin slot
. It detects the presence of light with a photoresistor and alerts the user with the vibrations of a pager motor. This breakthrough in coin slot technology will prevent dryness and certainly reduce our exposure to domestic terrorism. We see plenty of room for future development; the Arduino is already capable of logging exactly how often your coin slot is exposed. Even if you feel this is more protection than your coin slot needs, we recommend
Neutrogena’s Coin Slot Cream
for general upkeep.

Yesterday, we featured [Andrew]’s
orientation aware camera
. We want to highlight another one of his projects:
LED Life
. It’s a 6×5 LED matrix playing Conway’s Game of Life. He used the low power MSP430
like our e-paper clock
. The best part of the writeup is his explanation of how Charlieplexing works. Microcontroller GPIO pins generally have three possible states: output high, output low, and input. This combined with the directional nature LEDs and some creative wiring means you can run a large matrix of individually addressable LEDs with just a few IO pins. Instead of just flipping the IO pins on and off you change their assigned state. Have a look at [Andrew]’s site for some great illustrations of how the system works. A video of his LED Life board is embedded below.

Vertical Axis Wind Turbine Update

[Faroun] sent in his
updated vertical wind turbine
. After running his
previous one
for a while, he felt that the motor he was using was inadequate, it required too high of RPM to produce what he wanted. He didn’t want to gear it up, fearing that the light construction couldn’t sustain rotation.
He built a new version that has the same surface area of fins, but much higher RPM. The new one, dubbed V8 is made mainly from PVC and an Amatek DC motor. His goal was to produce 100 watts at 35km/h. He doesn’t really state whether or not he achieved it though.

This machine would take forever to simply payback the amount of energy it took to build.but cheers to trying.",

[Alpay Kasal] of Lit Studios and [Sam Ewen] created this patent-pending
interactive mirror
after being inspired by dielectric glass mirrors with built-in LCD panels, and wanting to add a human touch. The end results look like a lot of fun. You can draw on the mirror and play games. According to [Kasal], mouse emulation is essential. The installation features proximity sensors and gesturing. Any game can be set up on it, which makes the possibilities endless… except these are the same people that built
LaserGames
so expect no further documentation about how it works.

ZigBee
is a low-power communication system using digital radios. It’s intended to be easier to work with than
Bluetooth
. Adafruit recently added an adapter board for Digi’s XBee product line and has put together a great how-to to show the devices potential. Using two XBee radios and adapters you can
wirelessly program an Arduino board
. This would be great if your Arduino was installed in an inaccessible area or maybe it’s over 100feet away from where you’re working. The radios do serial communication just fine. What the how-to covers is getting the reset line working so the Arduino can restart automatically after you program it. Once the radio pair is configured properly, it will pass the RTS line state directly from one device to the other.

dug up
this excellent
robot fish prototype project
. The PPF-O9 has three servos. One on the forward fins to control depth, one on the middle joint, and one final one drives the tail fin. The battery box is mounted to the underside. The control scheme is interesting: the right stick controls left/right and up/down while the left stick controls the frequency and amplitude of the motion. They say the robot is fairly stable, but swimming and turning can be slow. They’ve included
CAD files for almost every component
to help you with your own designs.
In June, we highlighted a
robofish designed for swarm communication
.

[Todd] sent in his
Hack-o’-lantern
just a bit late for Halloween. He did a good job of working with the logo considering the difficulty it poses for pumpkin carving. We would have been proud to have that on our porch for the kids to steal and smash in the road. Since others in the past have also done
Hack a Day pumpkins
, maybe this will spawn a Hack a Day pumpkin carving contest next year. If he had enough time to get the green LED working, it would have been that much sweeter; everything is better with electronics.

In case you were wondering what industrious hacker [Joe Grand] was doing when he’s not building stuff for
Prototype This!
, designing
Defcon badges
, or
testifying before congress
, it’s this: The BSoDomizer is a VGA pass through device that displays an image of your choice on the victim’s screen. It can do this either periodically or via an IR trigger. The image of choice is a Windows style Blue Screen of Death. It’s powered by a watch battery. The project site has all the schematics you need plus
ASCII
goatse imagery;
you’ve been warned
. Embedded below is a demo of the device. We unfortunately didn’t get to see it when it was originally presented during
Defcon
16.

This hexapod was sent to us on the
tipline
from [Jamie]. If you want to take the six-legged robot a bit farther than our earlier posts,
here
and
here
, this is the
hexapod
for you. The structural pieces were modeled, and cut out of 3mm thick plywood using CNC. He used TO-220 transistor nylon isolation mounts for the bearings, and bolts and locknuts at each joints. The main body houses eight servos, six for the legs and two for a camera head pan and tilt. There are another six servos, one for each leg, to lift the feet. The whole thing is controlled by an Atmel AT90S8515 clocked at 8 Mhz. The code was compiled using WinAVR free GCC GNU-C. He uses a
PlayStation controller
to help debug the walk cycles, and change parameters as needed. Watch a video after the jump.

Flash Sync Port Hacking

"camera",

"flash trigger",
"sync port"

Reader [Adrian] picked up a couple cheap wireless flash triggers on eBay. Unfortunately, his Sigma EF-500 DG Super strobe doesn’t have the necessary sync port to make use of these. He popped the device open to try to figure out a way to
trigger the device manually
. The first idea was to use the test button to fire the device. Thanks to lag, it didn’t work for anything under 1/20th. The solution was to go straight for the optical trigger. [Adrian] has posted some teardown pictures that will help you determine the appropriate solder points for your own mod. The only bit that’s left is
adding a 3.5mm mono headphone jack
as a sync port. He also has a post on modifying the flash
for greater head movement
.

We spent our Halloween dressed as an irate traveler as we flew cross country, but it looks like a lot of people were having much more fun. [flaming_pele!]’s
Aliens power loader
is one of the best costumes we’ve seen yet. He built it by referencing a 1/12th model kit and a lot of photos. The final costume is about 80% full size which gets it under their 8 foot ceilings. There’s a video of the suit embedded below. Our love of power suits was documented fairly well in
our roundup post this summer
. Make found two other related costumes: a
Star Wars AT-ST
and a
generic mech constructed from packing foam
. Did any of you dress as something truly nerdy for Halloween?

Here’s a simple project for your Halloween celebration. The other day while looking through our box of Halloween decorations, we noticed that the incandescent lamp in one of the jack-o’-lanterns was burnt out. Instead of simply replacing the outdated bulb, we decided to build a small dark detecting circuit with 2 yellow LEDs based on
this Evil Mad Scientist Laboratories design
. After successfully building the circuit, we took the project one step further by incorporating an Atmel ATtiny13 microcontroller. The code switches the LEDs on and off randomly for a flickering effect and is
based on this instructable
. Below is the schematic we created in EAGLE and a parts list.
T1, T2: 2N3904 transistors
T3: LTR-3208E phototransistor
LED1, LED2: 10mm diffused yellow LEDs
R1: 5kohm resistor
R2, R3: 50ohm resistors
IC1: Atmel ATtiny13
Source: 2xAA battery case with batteries

In combining a flicker program with the above circuit, I used the ATTINY45 to replace the transistors. My whole circuit is 2 resistors, 2 LEDs, the phototransistor and the ATTINY45. I use the ADC to read the phototransistor. I have the Tiny sleep and only wake on light. On waking, it lights up the LEDs, one red and the other yellow. The LEDs are driven by PWM. The each are turned on to a random level of brightness for a random duration. With minor tweaking, I got a wonderful candle effect without any harsh edges. I limit the PWM between 127 and 255 in intensity. The rate is controlled by a constant. I hooked it up to two AA batteries. The circuit ran all night in my pumpkins this season for about 2 weeks. There was fade as the batteries died, but they are still running now and I pulled them from the pumpkins about a week ago. Looks like 2 weeks ssolid performance, and 2 more weeks adequate performance. I am working on putting a schematic together in Eagle, but am having trouble locating the symbol and foot print. My first Eagle project, so it may take some time.",

Battle Of The Thumb Drive Linux Distros

We were expecting eye gouging and body slams, but this
review of several thumb drive Linux distributions
will do. They compared Damn Small Linux, Puppy Linux, Xubuntu, and Fedora. They don’t mention why they chose these four specifically, as
UNetbootin
has many many distributions available. They put each through its paces, listing common issues and boot up speed.
Their conclusion was that puppy Linux was preferable as it has a graphically nice interface and the ability to have persistent data storage on the disk. They have a poll going though, so head over and voice your opinion.

With the election coming up in less than a week, voting machine security (or the lack thereof) is critical, especially with the popularity of
early voting
this year. While we’ve previously discussed
voting machine insecurities
, it looks like the problems haven’t been fixed, and in some cases, it’s escalated.
Voters in states like West Virginia and Tennessee have complained
about voting machines “flipping” their votes, even after they were recalibrated as in the video above. Voters have been advised to
avoid voting straight Republican or Democratic tickets
, to avoid the likelihood of their votes being flipped. What if you actually do want to vote a straight ticket?
Video the Vote
is an organization that advises documenting as much of your voting process as possible. Other ways you can protect your vote include
voting absentee
so that a paper trail is available, and
refusing to accept provisional ballots
, which are often thrown out. After seeing
videos of ROM swapping
and finding out that the locks can be
opened with hotel minibar keys
, we’re waiting to see what’s going to fail this year… and voting absentee.

European researchers in the I-SWARM project are
hard at work developing small, autonomous robots
that can work together and communicate to perform different functions. They successfully built two types of robots: the I-SWARM, and the Jasmine robots. The I-SWARM robots are three millimeters in size, are powered by a solar cell, and move by vibration. The Jasmine robots are the size of two-Euro coins, have small wheels, and are powered by battery. These tiny robots have several advantages over their bulky predecessors, such as high redundancy, greater flexibility, and the ability to manage tough terrain. They could even be used to repair larger robots. They also come with distinct challenges. Because of their minuscule size, programming memory is necessarily limited, and the team had to come up with special algorithms to manage and control the machines. Though they haven’t been able to meet their goal of making a thousand of them, the researchers are hopeful and confident about their abilities to mass produce the robots cheaply.

The concept is fairly new when we think of the robotic area as a whole people have been building robots for over 40 years the swarm technology is newer and not yet reliable.. watch the videos and read up on this you will see sometimes a robot in a swarm gets confused and just sits there forever,,,, er space junk!@omega it does look like a table with an ant farm lol",

[Rick] has been building Tesla turbines in various ways and posting his projects to youtube. For those who are unfamiliar, a
tesla turbine
is a fanless turbine that uses a smooth central disk spun by friction from a gas or fluid. Since the turbine itself has no protrusions, it is extremely stable. There are lots of other benefits, which can be explored on the Wikipedia page. [Rick], as you can see from the video above has found several uses for them, from Halloween props, to
generators for lights
, to an
automated shake flashlight shaker
, you can even watch him
rev one up to destruction
. Though most of these are at relatively low speeds, he has shown that he can make one from CD spindles that is stable enough to reach
10,000 RPM
. [Rick] admits that all they really do is spin fast and make cool noises, but they do that pretty well.
Update: Moments after this was published, we found an instructable by [Rick] on
how to build a blender using a tesla turbine
.

Air compressors are already fairly common, and if your turbine were many layers deep it might be able to put enough torque out for some air tools, though I’m not sure about the efficiency compared to normal air tool mechanisms.",

I blew the top off one last week.(movie to come, hehe)On air pressure this turbine needs 15,000 rpm to begin to make decent torque…30,000 is a good working rpm. The turbine can be geared down for more torque at less rpm, or a high-speed alternator can be fitted.Unfortunately my materials (magnets, CD discs, glue) will explode at any more than 15,000 rpm. So currently the turbine needs to be run in an inefficient rpm range. It can’t get into the range of power it wants to without modification, but it does hint at the potential in a fun way.The noise really isn’t an issue. Usually, commercial Tesla turbines get quieter with speed, especially above 20,000 rpm. They run much quieter than bladed turbines.And they can take the abuse of dirty fuels, pressure surges, etc in commercial applications much better than bladed turbines. The Tesla Turbine is the only turbine type able to run on 100% biomass combustion products.“Air tools are common” about sums it up…My CD turbine would have less efficiency and can’t compete…except in fun factor!!",

He came up with the Polyphase AC system we use as a nation to send power from a generating station(Dam’s, nuclear, coal, solar, wind, etc.) uses a transformer that he and his financial backer and inventor Westinghouse purchased from a french inventor and improved on. After the power is stepped up to a very high voltage it is transmitted along power lines and then stepped back down to useable levels. TESLA is responsible for more than anyone wants to admit. He got us the AC system and fought Edison and his DC power generation system that would require generating machines every few miles. He proved the existence of the rotating magnetic field used in pretty much all DC motors to this day. The brushless DC motor. Also did a lot of work in the fields of radar, wireless power transmission, wireless communication, flourescent lighting(He made lights that didn’t need to be plugged in!), he created his own oscillators(said to almost shake a building frame of a skyscraper in NY to the ground from repeated Harmonics), and he designed the first generator used on Niagra Falls. He has been known to say that the Tesla Turbine was his best invention. So anyway, you never hear about Tesla in School it’s always Edison… But Tesla was undoubtably the best Electrical engineer of his time.",

How do hardware geeks carve pumpkins? With
giant home made CNC mills
, that’s how. Using the
open source CNC kit from Lumenlab.com
, they converted a photograph into g-code, then fed it to the machine. After about 20 minutes of pumpkin drilling, they had this beautiful jack-o’-lantern. We are definitely jealous. Keep up the good work Lumenlab.

[foo] sent in this amazingly well done mod to
add an SNES controller to a PSP
. He was contacted with a request to mod a
PSP
for someone who had limited use of one hand. The PSP controls were too difficult for her, but miraculously, she could play an SNES controller well. The quality of the mod is very nice. [foo] has added a port on the back that the controller plugs into. Other than the port on the back, the PSP looks completely stock and functions fine. When plugged in, the cable and plug act as a stand for the PSP too. Check out the video after the break for more.

Quick Cheap Cassette Adapter

[Dane] sent us this
super quick tape adapter
project. Yes, we know we can go buy one of these for pretty cheap and it will probably sound much better, but really, wouldn’t it be cool to make one? Using a headphone adapter, a couple resisters, some wire, and an old cassette tape, [Dane] shows us how easy it is to build one of our own. You are basically pushing the signal from the headphones through a coil that is up against the tape read head. This is a perfect project to teach beginners about magnetic fields.
[Dane] has sent in some stuff before. You may recall his
PWM adio generation with an AVR
post several months ago.

Open Source Hardware Inspires Innovation

Technology Review turns the
spotlight on the open source hardware movement
. Open source hardware is hardly a new concept, but lately it’s been getting a lot more attention, with the help of magazines like
MAKE
and websites like
Instructables
.
Chumby
, a company that sells a modifiable cube with a screen, embedded computer, and a Wi-Fi connection, designed their product to be easily hackable. The openness of the product caused a community heavily invested in the product’s development to be created. The growth of such communities has also sparked interest from corporations such as
Nokia
, which is collaborating with
MIT
on open source video decoders. They recognized that opening up would cause development time to be reduced and provide greater flexibility, allowing them to allocate resources to other areas, including marketing and brand development. [Jamey Hicks], director of the Nokia Research Center in Cambridge, believes that the open source movement can even complement closed designs, as long as it’s handled appropriately. With greater access to sophisticated software tools and resources, the barriers to entry keep falling away, and it’s much easier for the world to discover the joys of tinkering and hacking.

Argue it any way you like, but I think it is a feature that should go away. It is becoming the only means of communication for millions of young people. (sure I agree it is up to parents to regulate this, but they don’t seem to be able to.) As far as sms/chat goes I think that cellphones and “mobile” PDA’s need to get a standard “communication” module and then we don’t pay $500 over and over again for less functionality than a 4 year old laptop.@Peter, the Openpandora is not “open hardware”, this is true. But the developer (Micheal Weston, a Canadian), is active in the user forums and has stated his desire to document all connections and has brought out as many of the unused BGA connections on traces as he can.As for “open” hardware, I think that is pretty much all you can hope for, it is mostly just a Ti OMAP, power/buffering circuitry, and a Wifi/BT chip anyway, not much to document.They even have it designed to boot off of SD cards if the flash fails (anybody else doing that in their handhelds?)@Chumby, your control scheme is weird, you cost too much (honestly people, buy a beagleboard and any HDMI/DVI/S-video/Composite screen, it can decode 720p for crying out loud, and has USB for interfacing with controls/sensors/video capture devices/etc.).I guess it might be interesting to hack, but I can’t stand the way it looks, if it is for hackers all they need is a bare PCB, they don’t pay for fabric and glue wrapped around their hardware.I may be confusing hardware hacking with the software hacking that chumbo here is designed for, but who cares, it isn’t really a great platform anyway.",

[Andrew Magill] just added his
Orientation Aware Camera
to the
Hack a Day Flickr Pool
. It uses a 3-axis magnetometer and 3-axis accelerometer. He didn’t want to spend too much effort on the USB side so he picked up USBMicro’s U421. It’s a fairly well documented preprogrammed microcontroller for USB. He later regretted this; his final sample rate was only 5Hz because of all the overhead. Using the positional data the, webcam image can be corrected for any sort of shaking. [Andrew] took this one step further by using OpenGL and stitching all of the video frames together live into a full panorama. Be sure to watch his excellent video demo embedded below.

Apart from general panoramic photography, I haven’t seen anything like this before, its so ‘immediate’ and rewarding! Especially where it can auto-correct camera orientation AND generate full 360degree views!Its just inspired!I for one though would love it if you would make it much more accurate, less jittery, and maybe faster, as I’m kind of thinking its got a sort of ‘unfinished’ look to it.But I do know where you’re coming from with the preference of that abstract visual effect.Thanks again!

Linear algebra says that you need two mutually orthogonal vectors to fully determine an orientation in 3D space. If I only had the accelerometers, I would only be able to determine pitch and roll, but never yaw. (Without looking, you can tell which position your body is in, but not which direction you’re facing, right?) Similarly with the magnetometers I could only determine yaw and pitch, but never roll. (Sort of.. Magnetic north actually points about 45 degrees into the ground around here.) So this wouldn’t really work with a wiimote, as it only has the accelerometers.I’m honored to be compared with Johnny Chung Lee- I remember being blown away by the simplicity and brilliance in what he did. In fact, his video inspired me to make this one.I think if I had a *MUCH* faster sample rate from the sensors, I could develop an algorithm to smooth out the jitters and improve accuracy. With such a slow sample rate, though, it doesn’t seem like there’s a lot I could do to improve the data from the current hardware without getting into some hardcore image analysis.",

If you’re prepared to do some off-line number crunching you can get good image registration using SIFT-based keypoints. An easy way to do this is using Autostitch, which can be automated although its not really designed to do this.check out the video example at the link below. I made this by “painting” a background panorama using a video camera, then stitching a live feed into the panorama. Autostitch works using only the images – your camera measures orientation, so if you waded through enough maths you should probably get a better result.http://stewartgreenhill.com/blog/2008/07/22/a-batch-controller-for-autostitch/",

Uv Oven From An IKEA Cabinet

This may not be an amazingly complicated project, but it is a very elegant and fairly cheap way of
building a UV oven
for exposing PCBs. [aris] started with an
IKEA FIRA
cabinet. He basically left the framework as an empty shell and made a make shift top hinged door to enclose it. Mounted in the top is an array of 35 UV LEDs powered by an HP printer transformer. He did not have a timer circuit, instead he just watched the clock and unplugged it at the right time. You can see from his pictures that his results were quite good.
If you don’t want that piece of furniture taking up room, and don’t mind using a little more elbow grease, you could follow our directions on how to
make your own single sided PCB
. If money isn’t an issue either, you can always just get your PCBs
laser etched
.

They then exposed the boards that now form the actual light box :)I went down to the local glass supplier to get two panes of 12″ square glass cut to sandwich the mask and board.There is also a 128×64 graphics LCD cut into the top that gives a nice display, and a rotary encoder switch (with button press) to give all of the input required.All this was run off a 5v 2A (but not using all 2 amps!) wall mounted transformer.-Andy",

[andrew] sent us this
proof of concept
. Based off of the
Spiech Clear view screen
, used in marine applications, it uses a spinning disk to keep a part of your vision free of water droplets. While you may not be too impressed by watching the video initially, keep in mind that this was a quick prototype. With some planning and a little work, this could be moved to a more convenient location and run by a side mounted motor. It could even be made to be removable for fair weather. It probably doesn’t do so well with mud though.

Wired posted a gallery covering an interesting phenomenon. When you unroll regular sticky tape it emits visible light, but what was recently discovered is that
under vacuum it actually emits x-rays
as well. They’re still trying to nail down the cause. Have a look at the gallery of UCLA’s research lab to see what kind of equipment you need to unroll tape in a vacuum.

"content": "A typical method of producing x-rays is to heat a tungsten filament in a vacuum. The elevated temperature causes electrons to be discharged into a vacuum. It’s called the thermionic effect.The discharge of photons from unrolling tape has been a known phenomenon for quite some time (I played with it as a kid too). It’s fascinating that this can produce high energy photons though. According to the article on ScienceNews.org, “At normal atmospheric pressure, the electrons are slowed down by air particles, so they never reach the speeds and energies required for making X-rays.” This I had expected was part of the reason. The tape is always emitting electrons, but the atmosphere slows them down.The other part (my own hypothesis), not mentioned, is the fact that the friction of pulling tape off of a roll actually can create noticable wasted heat energy. I’ve used a lot of tape in a very short time and the roll can become quite warm. This additional heat energy may be contributing to the thermionic effect at lower temperatures than are needed normally. It is also possible that the airborn particles of adhesive (identifiable by smell) may serve as accidental lasing medium or form excimers that become excited in the presence of the emitted electrons. I’m going out on a limb, but it’s the best I can do since they can’t explain the effect themselves.Any way you slice it, it’s very cool.",

I would expect a lot more voltage in a vacuume with no gas to ionise and discharge the capacitance.X-Rays are not formed by the *acceleration* of electrons, but rather the sudden stop when very fast electrons hit a target, normally metallic, causing secondary x-ray emission.For perspective, a friend has a power supply from a medical x-ray machine, an oil-filled tank about 1.5 ft cube with huge HV bushings on top, rated at truly lethal 100kV at ~100mA (short duty-cycle). Because of this sort of power level some x-ray tubes have rotating targets so they don’t melt.Very little risk of radiation sickness from sticky tape I think, even in space. :)",

Microsoft Anti-piracy Solution Backfires In China

There’s no doubt that software piracy is rampant in China. Microsoft attempted to remedy the problem with its new version of
Windows Genuine Advantage anti-piracy program
, which will turn the screen black every hour if the system fails the validation test. Previous versions just notified the user that they were using pirated software. You can imagine this
didn’t go over too well with the Chinese
, who were outraged by the inconvenience and more than one even accused Microsoft of hacking into their computers. A genuine, unpirated version of Windows costs over 1000 RMB, which is more than most Chinese make in a month. Contrast that with the 5 RMB (less than one US dollar) for the pirated version, and you’ve got a no-brainer.

At the major universities, there will be no shortage of laptops, even apple laptops running a dual boot with a pirated version of windows which the students can download from their university’s ftp server.

Too much nagging and companies will spend the time to change to Mac or Linux. Not enough and nobody will change.Just a thought for MS … start with a 2 second black screen. Every hour longer, make it 2 seconds longer. Add a button to purchase maintenance for $5/month. When bought, they stop the nagging for 31 days, then it starts over.

Apple really isn’t a real alternative to Windows, it’s actually worse, not only do you have to buy their (ugly) software but they lock you into hardware too. I know they are getting better at being open but I could see this happening in China with apples installed on illegal hardware or illegal copies of the OS getting “hacked”.I’m no communist but digital “property” is the only product that can be shared in a communist fashion, so it seems unnatural to enforce the copyright system on it (which was more invented to keep bogus copies of books off the streets than it was to limit the distribution of them)",

The computers are at least the same price as here anyway!Many chinese do not actually know they are buying fake, they simply do not understand licences.

As you can plainly see, we’re embracing
International Caps Lock Day
with full gusto. Go ahead, try it out in the comments. Caps lock is the cruise control for cool. Surprisingly, there are quite a few full time haters of the key running campaigns:
CAPSoff
and
anticAPSLOCK
actually united to form
CAPSoff.org
to further development of a caps lock free keyboard.
Once you’re tired of yelling at people online (like that’ll happen), you might attempt to do something useful with the key. In OSX, you can remap the caps lock key in System Preferences > Keyboard & Mouse >
Modifier Keys
. You can make it an extra Command, Control, Option, or select No Action. If you want to map it to another key entirely, try a program like
fKeys
. You could map it to Esc to make
Vim
—THE BEST TEXT EDITOR EVER—easy to use. In Windows, try this
handy guide from TechRepublic
for remapping your keys.
If ease of use is not your goal, you could always make a
random caps locker hardware dongle
.

Presto, no more forced lowercase on everything. Alternatively, you can put “uppercase” instead of “none” for forced caps, or “capitalized” to force everything word to have the first letter capitalized. Note, this will effect everything, not just hackaday.com, so “none” will completely render every css without the other text-transform options.",

Viddy yourself this Halloween standing out amongst your droogs with this
Mini-POV bowler
. We’ll quit with the
nadsat
so as to avoid a kick to the yarbles, you have our sincerest appy polly loggy for starting in the first place. [cheeto4493] modified a Mini-POV to sit atop the bowler with an extension hanging out toward the brim that houses the lights. A motor, mounted inside the hat spins the entire device. Some counterweight was necessary to keep the whole thing from wobbling too much.
It is worth noting that, in person, the message scrolls slowly by. The refresh rate on the camera causes it to seem to jump around in the video.

This
Reflow toaster oven project
(pdf) was part of a
contest back in early 2007
, but it is new to us. We’ve seen
several approaches
to reflowing, but a bread toaster hasn’t been one of them. This has a nice controller with a large Nokia 3310 display too.

USB Authenticated Deadbolt Lock

[
"deadbolt",
"entry",
"freeduino",
"lock"
] |
The Makers local 256 sent us this
USB authenticated deadbolt prject
. For roughly $60 these guys built an authentication system that reads the serial number off of the chip in a USB storage device. The actual content on the memory in the USB device is not used at all. They are using a Freeduino board to control its behavior. It has a magnetic sensor that keeps it from initiating the lock when the door is open. They mention that they are using Transparent Aluminum as an enclosure, we assume they mean the
Star Trek variety
, not
Aluminium oxynitride
. Be sure to check out the video after the break.
[youtube=http://www.youtube.com/watch?v=JKTXRlaXLDQ]
Also, we received a security certificate warning when going to their wiki. Everything seems fine, just didn’t want you guys to be scared away.

For people who miss the golden age of Atari music, you can recreate the magic of 8 bit music with the
-hard plAYer-
. [Tolaemon] put a lot of thought and work into this hardware player. From the AY-38912 programmable sound generator, which used to be in old computers like the
Atari
or
Colour Genie
, to working with the
YM file format
, each piece is put together with the utmost care. [Tolaemon] also provides his design,
firmware
(ZIP), and
parts
list so that you can make your own hardware player.

Google has
officially released
the
Android source code
. While the
T-Mobile G1
is being released tomorrow—
some already have it
—it is just one
Android device
. The availability of the source means that the platform could be port to almost any device. It’s a complete embedded
Linux package
and we’ve already seen it
running on the N810
. We can’t wait to see what hacks come out of this.

All comments on style aside, these are pretty cool. They are
power generating shoes
, that use water and a small turbine. As you step down, the water is forced through the turbine and recirculated back to the reservoir when you lift your foot. It may not change the world, but is definitely interesting. This reminds us of those
shoes that we used to pump up til they burst
.

DIP through-hole chips are an old package with instantly recognizable
dual in-line
pin rows. Beginners love these chips because they’re large and look easy to solder; we abhor them because we hate messing around with the drill. Whatever your motivation for using a through-hole chip, use a socket whenever possible. A circuit board with socketed chips is easy to test without endangering the parts, and ICs can be removed, tested, and replaced, without resorting to a soldering iron. This week, by request, we looked at several common through-hole chip sockets.
DIP sockets are available in almost any pin-count, or you can use individual strips to make a custom size (Mouser #
40-0518-10
). ICs with less than 40 pins usually have .300″ row spacing, but many 40+ pin ICs are .600″ wide. Footprints are included in the
Cadsoft Eagle
default
ic-package
library as DIL
xx
. Below is a list of our most commonly used DIP sockets.
8 pin .300″ socket
(Mouser#
571-1-390261-2
, $0.
14)
This socket is useful for
op-amps
and small microcontrollers, like the
12F629
used in the
Esquire e-paper cover
.
14 pin .300″ socket
(
Mouser #
571-1-390261-3
, $0.15)
Another small socket we occasionally need.
18 pin .300″ socket
(
Mouser #
571-1-390261-5
, $0.18)
A very common chip size for lots of microcontrollers and
7400 series
parts
28 pin .300″ socket
(
Mouser #
571-1-390261-9
, $0.30)
Another common size for through-hole microcontrollers, and chips like the
TLC5940
16 channel
pulse-width modulator
. Check your datasheet because a .600″ row spacing 28 pin DIP package also exists.
40 pin .600″ socket
(
Mouser #
571-1-390262-5
, $0.41
)
Watch out, this is a wide socket for chips with .600″ row spacing. Fits common 40 pin chips, like the
PIC 18F4455
USB microcontroller.

I think it’s a fantastic idea that brings up some very fundamental issues.However, my one complaint about the parts articles has to do with the follow-through, that they don’t go quite deep enough into the given topic. For instance, on this post it would have been very nice in this article to mention the difference between machine pin sockets and the spring-action sockets pictured above. It would have been nice to at least mention zero-input force (ZIF) sockets for applications where easy extraction is much more important than board space. It might have even been worthwhile to mention something about more complex sockets for higher pin count chips, and I could probably ramble on.I have similar criticisms of the stereo jack article, the microSD card article, etc. I think that the LM317 article had the best background information (or at least links to helpful calculators, etc).I think you guys are doing a very good thing by including these parts articles as a reoccurring type. However, I think you could improve them greatly by adding a little more substance (background, implementation, schematics, links to sample code or projects, etc).~ben",

The RepRap is a self-copying 3D printer. The project has published plans for creating a
lasercut acrylic version of the device
. They call it a RepStrap since once assembled it could produce printed plastic versions of the machine components, bootstrapping true RepRaps. The
plans are available
for Ponoko an on-demand product service, and it would cost ~$380 if you used their service. The plans are free, so you could get them manufactured by other means. [vik] is still putting together the
assembly instructions
. He hopes to have an all inclusive electronics kit at some point too. This is another great step towards putting desktop manufacturing within reach of everyone.

It’s not officially supported, but PCBs can be milled without too much difficulty, so if you wanted you could use one of these to produce the circuits for replication. Since the pcbs are usually in stock through rrrf.org, it’s not necessarily to your benefit as a builder, but it’s doable. Stepper motors are more difficult, but there is someone working on milling and wrapping his own.",

The latest generation of
Arduino
hardware has been released. The
Arduino Duemilanove
(2009 in Italian) has the same form factor as previous generations. The specs are essentially identical to the
Diecimila
, but there have been a few changes to the hardware. The power source is no longer chosen using a jumper. A MOSFET and dual OPAMP have been added to the board to automatically selected between USB power and the external plug. Automatic hardware resets are optional now. Next to the USB port are two solder pads labeled RESET-EN. Cut the trace between them to kill the reset. If you ever want it back, just bridge the pads. The hardware was updated to correspond with the release of Arduino cofounder [Massimo Banzi]’s
new book
.

[Randomskk] has been attempting to make electronic fireflies for quite some time and finally settled on a design he liked. His
jar of fireflies
uses an ATtiny13 to control a set of 12 matrixed LEDs. The green SMD LEDs are each soldered to a pair of thin wires that hang down into the jar. The software picks an LED at random to flash and then flashes it 1-3 times. The random seed is incremented each time the jar is turned on, so you’ll get 255 different patterns. The power is just a standard coin cell. The project is fairly simple electrically, but the LED soldering could prove difficult. It was inspired by this
firefly jar project
. Check out [Alex]’s
synchronizing fireflies
too. A video of the jar is available below.

An outdoors version with LEDs rigged to plants could really benefit from a medium sized panel hidden somewhere, though!frollard: the idea is the same, but the implementation is pretty different – the one at instructables has multiple songs and lights up a few at once, but takes ten times as much code (so needs an attiny45) and only controls six LEDs. I still think having 12 LEDs controlled by 5 pins and still having hardware PWM control of all of them is interesting, even if it is basically charlieplexing.",

Yesterday, Gizmodo published a
roundup of wearable gadgets
for people who “don’t mind looking like a tool”. It’s interesting to see what has been deemed commercially viable and put into mass production. The list covers HMDs, embedded WiFi detectors, integrated keyboards, tech jackets, speaker hats, and others. We thought you might find some inspiration from the list for your next project. In the past, we embedded a
WiFi detector in a backpack strap
for our Engadget how-to. The natural choice for wearable projects is the
LilyPad Arduino
which was featured most recently in the
turn signal jacket
.

Chrome And Firefox Showing JavaScript Improvements

With new betas for both
Firefox
and
Chrome
being released, CNET decided to find out
how good their JavaScript performance was
. Both browsers got a performance boost with Firefox slightly edging out Chrome. You have to
turn on TraceMonkey
, Firefox’s new Javascript engine in 3.1b1, to get the improvement. We never thought Google was that serious about building a new browser. They just want wanted Firefox to get their act together and suck less. It seems to be working.

We’re not 100% sure
what exactly is going on here
. It appears to be a massive
evaporative cooling
rig for a computer, though the title has us wondering if it doesn’t have any other uses. There isn’t much of a description, but we felt the sheer magnitude of this cooling system warranted some publicity. Some digging around shows that this was out in 2003, but it is new to us.

The cooler acts as a heat exchanger between the cool water circulated above it and a closed circulating system between the cpu block and a coiled copper tube inside the cooler so the water going exposed to the air is never the same water going to the cpu block. The end effect is essentially replacing a traditional water cooling system’s radiator with a copper pipe in a fish tank with its filters going all the time to evaporate it and keep it cool.",

[Ben Heck], in a display of true hacker spirit, has released a tutorial on
how to mod the Access Controller
.
We have been waiting
for it, but we can’t help but commend the detail he goes into. He lists pinouts, as well as digi-key part numbers for various replacement parts. Great job as usual [ben].

Internal Wireless Mouse On A Dell Mini 9

[strider_mt2k] sent in this
new Dell Mini 9 hack
. After seeing the recent
GPS in a Dell Mini9
project, he decided to jump in and do some hacking of his own. His idea was to integrate his Logitech wireless mouse receiver internally. He basically added an internal usb port, allowing for future replacements if the mouse should it get broken or upgraded. The final result is completely hidden. There was plenty of space in the case, so there’s no bulge at all.
