[Andrew] made this
DVD dispenser
for his senior project in high school. It is using an ATmega8515 for the brains, and a custom coded driver for the LCD. As you can see in the video, after the break, you can select a
DVD
by various identifiers such as genre or title. It then pushes that DVD out of the rack so you can grab it. Right now, all the DVDs have to be placed in predetermined positions, but it’s not a bad start at all. Thanks for sending this in [Andrew].

N8VEM Computer With A 3Km Wireless Link

[James] sent in this project in which he
built a tiny computer with text based OS and a 3Km wireless link
. The details are a bit scarce, but he used an N8VEM, a Propeller Pocket Term, a 4 line LCD and an RF Transceiver to build it. It runs CP/M, the text based operating system and uses less than a half of a watt, without the vga monitor. With a total cost of 145 and 4 serial ports for sensors, this thing could come in handy. Especially since its low power consumption could allow it to be solar powered. You may recall the N8VEM from
an earlier
post we did.

"content": "Yikes, I’d better reply to a few of these!1) Solar is where this is heading. This started off as a simple picaxe repeaterhttp://www.picaxe.orconhosting.net.nz/all3.jpgbut when you get 10 nodes and they are all talking on the same frequency you get data clashes. And the software to handle that ends up too big to fit in a picaxe. And then you need to update the program out in the field on 10 nodes, and that takes ages, and so you need a system that can automatically transfer updates through the wireless system. I think CP/M is the simplest operating system that can do this, but xbee might be able to, and perhaps there are others. I want to send “real” data through the network, eg have a PC take a picture and turn it into a .jpg and send that jpg through multiple nodes and have it come out the other end. Without having to pay a mobile phone company for the prvilige.2) Anyone interested in building one, come and join the N8VEM open source projecthttp://groups.google.com.au/group/n8vemThis stuff is not that simple, and a full description runs to many pages (in fact to a whole separate websitehttp://n8vem-sbc.pbwiki.com/). It didn’t exist only a few months ago, but the bit that I like is that everything is open source and nothing is tied to a single source or manufacturer and that many people are contributing.3) Cost of 145 – oops, yes that should be US$145.4) The range depends on which module and how high the antenna is, but the major factor is the super senstivity of the receiver. This enables the transmitter power to be kept low which conserves battery power and keeps the authorities happy. A yagi boosts the range even furtherhttp://www.yishi.net.cn/product_detail.asp?id=53&fid=1715) RF modules are athttp://www.yishi.net.cn/index.asp?id=476) Kantronics KPC? I’ve just checked that out and it looks sweet. I reckon we could interface to that…7) Re “Call me when they do moon bounce digital communications on this thing”. Yea, I know it doesn’t look so impressive on a bench. The aim is to leave off the VGA display and have these things out in the field doing things like measuring tank levels and opening gates and turning on pumps, and do it all with solar power. But it has enough smarts to handle the packet system for the transponder on the space station and just needs a radio with enough power (and ?a ham license)http://www.rac.ca/ariss/arispak2.htm8) Yes it can run your C128 programs.9) The history of CP/M is fascinating. DIR is both a DOS and CP/M command.10) This isn’t linux but if you know how to use any text based operating system it is pretty easy to learn as there are only about 10 commands used commonly in cp/m. DIR for directory, ERA to erase a file, TYPE to type a text file on the screen, PIP to do file copy, and type the name of a file to run it. Simple versions of many popular languages are available too, like Basic and C.11) I don’t know about decoding an MP3. Ipods are so cheap though.12) Yes SD mass storage is on the “to do” list. Indeed, the next thing on the list is to take the whole project and fit it into a single 40 pin Propeller chip.",

N8VEM builders are making their own stuff too which is a lot of fun. If you would like to build your own Z80 computer stop on by we are always looking for hobbyists to come build their own peripherals and contribute back.There are bunch of related projects too like the PockeTerm and mini-N8VEM and other things too.Thanks and have a nice day!Andrew Lynch, 73 de N8VEM",

Log into the propeller discussion forum as this is being actively discussed.And the prop chip comes in much smaller packages.It certainly is going to get smaller.

Many of our cherished computers and consoles from the past have not stood up well over time. It’s not the hardware as much as the color. From Commodores, Apples, to Super Nintendos, the machines have slowly drifted towards a sickly yellow and even brown. The culprit appears to be the fire retardant chemicals used in the plastics. Amiga enthusiasts have spent the last year perfecting a technique that restores the plastic of these machines to its original splendor. Dubbed ‘
Retr0brite
‘ it’s a gel made from hydrogen peroxide, xanthan gum, glycerine, and ‘Oxy’ style laundry booster. The results are really impressive. If you do start restoring your own machines, caution should be used since it requires strong concentrations of hydrogen peroxide typically employed in bleaching hair.

Microchip’s new
23K256
is a serially interfaced 32 kilobyte
SRAM
memory chip, available in 8 pin DIP and 8 pin SO packages. SRAM, like
EEPROM
, is a data storage medium. Data stored in SRAM is lost without constant power, but it’s really fast and there’s no limits to the number of write cycles. EERPOM stores data even without power, but it’s slow and usually limited to around a million write cycles.
32K SRAM chips typically have 15 address lines and 8 data lines, like the
IS61LV256AL
we used on our
CPLD development board
. The 23K256 requires just four signal lines, but sacrifices the speed of a parallel memory interface. It’s a great way to add extra memory to a low-pin count microcontroller without routing 23 signal traces. We’ll show you how to interface this chip below.

We connected the 23K256 to our
Bus Pirate universal serial interface tool
as shown in the table. It’s very important to power the chip using only the Bus Pirate’s 3.3volt supply, the 23K256 isn’t rated for 5volts.
The Bus Pirate is an easy way to learn about a chip without writing any code, but the same principals apply to using the 23K256 with any microcontroller. This demonstration uses the latest version of the Bus Pirate firmware (26-FEB-2009), which you can download from our
Google Code SVN
.

SPI>
First, we put the Bus Pirate into SPI mode at 30KHz and chose the default settings for all options. We enabled the Bus Pirate’s on-board 3.3volt power supply with a capital ‘W’.
Configuration register
bit 7,6 = byte (00) page (10) sequence (01) mode
bit 0 = Hold disabled (1)
Data is stored inside the 23K256 in 1024 pages that each contain 32bytes. The scope of reads and writes is set by bit 7 and 6 of the configuration register. Storage can be accessed by the byte (00), by 32byte pages (10), or sequentially through the entire 32K (01). We’ll work in sequence mode, which gives us access to read and write any length of data, anywhere in the 32K of storage space.
The hold pin is used to pause transfers when other chips on the same bus need to be accessed. Bit 0 of the configuration register controls the hold pin. When set to 1, the hold pin is disabled. We tied hold to ground for normal operation, but its functionality can be completely disabled by setting bit 0.
The configuration register is changed by sending the
write configuration command
(0b00000001) and the new settings.
SPI>[
0b1
0b01000001
]
<–update config register
CS ENABLED
WRITE: 0x01
<–write config command
WRITE: 0x41
<–value to write
CS DISABLED
SPI>
We start an SPI transaction by enabling the 23K256 chip select line ([). We send the write configuration command (
0b1, 0x01, or 1
), followed by the new settings for the configuration register (
0b01000001, 0x41
). We set bit 6 for sequential access mode, and set bit 0 to disable the hold pin function. Bits 5-1 have no function, but the datasheet says to always write 0. The transaction concludes by disabling the chip select signal (]).
SPI>[
0b101
r
]
CS ENABLED
WRITE: 0x05
<–read config register
READ: 0x41
<–value read
CS DISABLED
SPI>
Next, we use the
read configuration register command
(
0b00000101, 0b101, 0x05, or 5
) to verify that the settings were properly written. This command returns one byte (
r
) which should match the value we wrote in the previous operation (0x41, or 0b01000001).
Data access
Now we can read and write data to the chip. Writes begin with the
data write command
(0b10, 0x02, or 2), followed by two bytes which determine where to write the data. The values to store are sent after the address. Depending on the access mode, a single byte, a page, or the entire memory can be filled in a single operation.
SPI>[

WRITE: 0x09
WRITE: 0x0A
CS DISABLED
SPI>
We start with the
write data command
(
0b10
) and set the write location to the beginning of the chip (
0 0
). We send a total of ten values to store, the numbers 1 to 10.
After writing the data, we can read it back with the
read data command
(0b00000011, 0b11, 0x03, or 3).

0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0A

SPI>
We send the read data command (
0b11
), followed by the address from which to start reading (
0 0
). We then read back 10 bytes (r:10). The 10 byte are the numbers 1 to 10, the same values we wrote in the previous step.

built this six legged little helicopter
. You can see that it is fairly mobile. You can also see that it doesn’t really make it off the ground really well. He must have gotten more power out of it though because he destroyed it in a crash the day after filming this. It is surprising how much character those six little legs add to the RC helicopter. This thing is almost as cute as something from
crabfu

a true hacker knows that you just can’t blow away the competition with a stock piece of equipment. Nerf warfare is no different. These guys did what they had to do to become the dominant force in their offices Nerf wars. They
built their own high power Nerf rifle
. Using some PVC, a sprinkler valve, and a bicycle pump, they made a Nerf gun that can fire roughly 300 feet. You can see a video of it in action after the break.

In order to update Skate or Die to a newer experience, [Jeff] has
hacked together a skateboard controller
for his Commodore 128. He’s using a parallax propeller to interface the skateboard to the unit, and another controller to boot up the game. Watch out Wii.

[Anthony] has
transformed a simple router board into a fully fledged Debian system
. The board is an
RB433AH
which has a 680Mhz development board with 3 LAN ports and 3 Mini PCI slots intended for routing tasks. At roughly $150, this could be a pretty versatile tool to have around. Possibly more useful than the
SheevaPlug
.

We’ve covered
automated plant growing
before, but that project might be overkill for many situations. Many of us don’t need our plants to have
facial expressions
either. Sometimes, we just need a little bit of help. This
automated grow light
is a nice little project that supplies decent light when necessary. You can download the source files on the tutorial. It is currently set to supply an additional 4 hours of light, detecting the low light levels to turn it on.

And that’s total power used by the LEDs. Assume a generous 50% efficiency for the LED, that’s about 100mW total radiated light.That poor Atmel proc is not going to be happy. Atmels can only source 45mA IIRC. So he’s running that poor drive transistor way hotter than it is designed for. Current is limited to about 45mA due to the small size of the drive transistors. So make that 50mW total radiated light.An external drive transistor (any old NPN switching transistor with a gate current limiting resistor will do) is necessary to source that much current. Or, alternatively, he could use multiple, (3 or more, IO pins to drive the leds.He should be sinking the current thru the micro, not sourcing — it’s more efficient to sink current thru a FET than to source due to easier electron vs hole mobility.A decoupling capacitor across the Vss/Vdd lines of the micro would help. Also a 10uF or so across the input power lines to reduce Vdd dropping when the leds turn on..",

For this reason I use white LEDs for “blue” light but have separate red LEDs for “red” light. Given this person is growing in a daylight lit room the plants are probably getting good blue light but lacking the intense red light which normally occurs naturally during sunrise/sunset.

The people at iFixit have shown that they’re still on top of their game by
tearing down the new Kindle 2
eBook
reader. The main processor is a 532MHz ARM-11 from Freescale. Interestly, there isn’t any significant circuitry behind the large keyboard; it seems its existence is just to hide the battery.

This little wall plug is actually a full computer
with 1.2GHz cpu, with 512MB of RAM and 512MB of of flash memory. It comes with versions of linux, ported for its ARM processor. At $50, this cool system could be finding itself in a lot of homes. You can get
more information
from the manufacturer. What uses can you think of for it?
[thanks, everyone who sent this in]

Many people don’t want to miss anything in their IRC room, so they “idle” or just leave the client open to capture all the conversations. It can be annoying to have it going in the background on your computer though. To remedy this, [Harrison]
built a simple computer from a propeller microcontroller that’s only purpose is to connect to IRC servers
. It can take a regular PS2 keyboard and works with a standard monitor at 1024×768. It’s compact size and low power requirements make it quite a useful tool to have around if you are always on IRC. you can download the source code and schematics on the site.
[Thanks Scott]

Parts: Analog Distance Sensors (Sharp GP2D12/2Y0A02)

Sharp GP2D12 and 2Y0A02 infrared rangers output a voltage proportionate to the distance of an object from the sensor. The GPD12 senses objects at a distance of 10-80cm, while the 2Y0A02 has twice the range.
We’ve previously looked at the
Sharp GP2Y0D02 digital proximity sensor
. It only signals the presence of objects, while the GP2D12 and 2Y0A02 measure distance to them. If you’ve got a GP2YoD02, it might still be possible to
tap the analog output
. We’ll show you how use these sensors below.
Sharp
GP2D12
, 10-80cm analog IR ranger (Digikey #
425-2046-ND
, $12.81).
Datasheet
(PDF).
Sharp
2Y0A02
, 20-150cm analog IR ranger (Digikey #
425-2062-ND
, $14.38).
Datasheet
(PDF).
We powered the sensors with a 5volt supply, as shown in the schematic above. We connected the output directly to a multimeter set to measure voltage. The datasheet also recommends a 10uF
bypass capacitor
between the power and ground pins, but we didn’t use it for this demonstration.
This graph shows the relationship between the output voltage of the GP2D12 and the distance of objects from the sensor (datasheet page 3, figure 6). You can find the distance/voltage curve for the 2Y0A02 in datasheet page 5, figure 2. There’s
an equation
to determine distance from the output voltage, or you could use a simple
lookup table
.
The output is unreliable for extremely close objects, seen as the small hump between 5 and 10cm. It’s possible to combat this by using several sensors with
overlapping ranges
, or by placing sensors so that
nothing can come within the minimum range
.
For an exhaustive discussion of the various Sharp proximity sensors, check out the
Sharp IR ranger information page
at Arconame.

Windows 95 Running On An N95

We’ve had this same hack submitted by two people, pointing to two
different
(

)
sources
(
translated
) today. It seems with a recent version of dos box, you can load windows 3.1 or windows 95 on N95 or N85 devices. They’re both in polish, so they may be the same people posting in different places. If you can follow along, there seems to be sufficient information to do this yourself. We don’t know why you would want to, but you could. You can see a video of it in action after the break.

When we showed you
Bar2d2
, the bar tending party bot, there was one huge hurdle left to solve. It was only a drink dispenser at that, while awesome, couldn’t actually mix drinks. That has been remedied in this update. Now, a computer handles all of the drink orders, then sends them via bluetooth to bar2d2. The drinks are mixed right there in front of you in the comforting blue glow of bar2d2’s neon. You can check out
more build pictures here

Last week at Black Hat DC, [Moxie Marlinspike] presented a novel way to hijack SSL. You can read about it in this
Forbes article
, but we highly recommend you watch the video.
sslstrip
can rewrite all https links as http, but it goes far beyond that. Using unicode characters that look similar to / and ? it can construct URLs with a valid certificate and then redirect the user to the original site after stealing their credentials. The attack can be very difficult for even above average users to notice. This attack requires access to the client’s network, but [Moxie] successfully ran it on a
Tor
exit node.

If they root the bank (e.g. Heartland) why bother with SSL traffic, just get the raw data. If they get your PC, they can grab keystrokes regardless of how good the network security is. And let’s face it, there are a lot of people who can be fooled by a site that just looks the same, never mind the URL or certificate. Although, just maybe, a wireless hotspot at a hotel or cafe might be a candidate for sslstrip. I think it would be hard – diverting traffic through a PC instead of going straight to a switch – but it’s probably easier than hacking an ISP or bank.The paper is worth a read:http://www.blackhat.com/presentations/bh-dc-09/Marlinspike/BlackHat-DC-09-Marlinspike-Defeating-SSL.pdf.. hey, maybe combine it with the BGP attack:https://www.defcon.org/images/defcon-16/dc16-presentations/defcon-16-pilosov-kapela.pdf(that was amazing – stole all the DEFCON traffic for an hour or so..)",

Window treatments? Polarization? At what point would proximity be hindered to a point of futility?D: the carrier laser would have to be in the non visible spectra to convey the data without detection of the target. That entails using a camera instead of a simple sensor to see the IR scatter from the laser on the “laptop”s screen or some area for alignment, greatly complicating things as the sample rate of the ccd would have to be very high, and thats contra indicative of using the on-board sound as an ADC. Sure, you could build some sort of alignment mechanics to compensate for a simple 3d index of the screen, with a reduction in return power over the angle of observation, but by then, the camera implementation would be cheaper.

4 Or More Servos On An Arduino

"roboduino",
"servo"
] |
The latest version of the
Arduino software
allows you to use more than two servos at a time.
Curious Inventor has posted a demo
showing how to run 4 servos from a keyboard input. The code should also work just fine on Arduino clones, like the Roboduino pictured above. They point out that if you are running version 12 of the software, some manual additions will be necessary.

Only mod I made to the TX was to replace the spring-loaded buddy-box switch with a throw switch.

I didn’t look at the lynxmotion firmware, but… You shift a 1 into your shift register, and it appears on output 0 connected to servo 0. Wait the desired pulse width (set the timer to interrupt, if you want.) Shift the existing 1 to the next output/servo, and wait the time associated with it. And so on. You might have minor glitches if servos on two separate shift registers happened to have their pulses expired at exactly the same time, but those would be on other order of microseconds long out of a millisecond pulse (and you could probably avoid them with clever code…)",

[vilxes91] sent in this cool little
false-theremin
(
translated
). Its a
pretty simple circuit
, that can fit in really small places. It isn’t a true theremen because it uses the amount of light coming in around the lid for the modulation. To play it, you turn it on and open it up, the more open the lid, the higher the pitch. You can see a video of it in action after the break.

[ghostwalker] has put together instructions for
running X11 on your Android device
. This means you can run a full-blown Linux desktop environment on your phone. It requires you to already have a Debian shell on the phone,
which we covered earlier
. Instead of having to come up with a custom display driver, it’s hooked to a
VNC
server. You can connect to it using an
Android VNC viewer
on the phone or via any other VNC client. The how-to suggests either
IceWM
or the even lighter-weight
LXDE
for a window manager. You could potentially install Gnome or KDE, but we’d be surprised if it was any faster than dog slow. Let us know if you have any success with this and what you think the best use is.

Host of the
Soldersmoke
podcast, [Bill Meara], contributed this guest post.
While the rest of the world is moving toward high speed broadband, some hams—including one Nobel Prize winner—are going in exactly the opposite direction. Our ‘QRSS’ mode makes use of an unusual mixture of modern digital signal processing (DSP), ancient Morse code, and simple homebrewed transmitters. Very narrow bandwidth is desirable because this reduces the noise in the radio communication channel, greatly improving the S/N ratio. But Shannon’s communication theory tells us that narrow bandwidth comes with a cost: slow data rates. In QRSS, beacon transmitters using only milliwatts churn out slow speed Morse ID signals on 10.140 MHz that are routinely picked up by DSP-based receivers on the other side of the globe. Many of the receivers, ‘grabbers’, have visual outputs that are available online in real time. QRSS has been getting a lot of attention on the
Soldersmoke
podcast and on the
Soldersmoke Blog
. For more information check out
this overview
and the
hardware involved
. Here’s a
gallery of received signals

If you don’t want to listen to someone on the Internet, you just don’t listen to them. You block them. You route around them. The EM spectrum doesn’t really work that way. If you want it to work reliably, you have to agree on how it should be used.An extreme example would be operating a high-power broadband transmitter in the 100MHz region. No one around would be able to listen to FM radio. They can’t just not listen, it’s *there* and there’s no alternative.Another reason to get licensed is that it’s *so* incredibly easy, that the drag of getting fined (or getting beat up by your neighbors) is just not worth it.Also, no one has found a reason to fight over the clouds yet.

NES Controller On A DS

You can get most of the old NES games for the DS, but they just don’t feel the same. Sure your hands still cramp up, but its just not the same cramp we remember. What is the solution?
Put an old Nintendo Entertainment System controller on your DS
. [Parker] did exactly that. The method he used is fairly strait forward. He opened the DS, wired extensions onto the buttons he wanted to use to a controller. Instead of making it permanent though, he chose to wire it through the GBA slot. This allows him to plug the controller in whenever he wants to use it. This reminds us of the
PSP with a SNES controller
we covered back in October.
You can see a video of it in action after the break. You’ll notice in the video, he has also modded his buttons to have LEDs behind them.
In the comments, [tri-edge] points out that you can
follow his
build in the acidmods forum. There seem to be some other variations as well, including an SNES controller.

Installing OSX on commodity PC hardware has advanced a lot since the early days of OSx86 when Apple switched to Intel. With the advent of
netbooks
, a new target platform has emerged; one that doesn’t have an official Apple equivalent. The small subset of models means that it’s easy to find someone else that has the same machine as you, but it still takes some forum walking to bring all the pieces together. Gizmodo has done this and compiled a
comprehensive guide for the Dell Mini 9
. The Mini 9 is a very nice machine and according to Boing Boing Gadgets’ chart, one of the
most compatible with OSX
. Earlier this week you could purchase a new one for just $200.
For Gizmodo’s install, they used a Leopard retail DVD with [Type11]’s
bootloader
. They’re breaking the EULA, but at least it’s not piracy. They had to use both a DVD drive and a USB hard drive because device recognition was flakey. Despite this, the actual install process doesn’t appear to be too difficult. They say all the hardware works, “The Mini 9 is a beautiful OS X machine.” Check out this Hackit to learn about
netbook OSX experiences from other Hack a Day readers

[Chris] wanted to do some macro photography, but found the price tag off putting. He was looking at roughly $800 for a decent macro lens. Instead, he decided to
build his own
. He wanted to build a lens that could be removed and used just like his normal lenses. He picked up a standard Canon AF lens for $10 to start with. He has posted detailed steps on how he modded it to work, and you can see the results are quite stunning. Great job [Chris]. If you want to try your hand at macro photography but don’t think you can pull of a job like this, you might want to check out the
pringles can macro lens

The team behind the the Tweet-a-Watt/
Wattcher
just
won first prize
at the Greener Gadgets design competition. The device is a hacked
Kill A Watt
that transmits power consumption using an XBee. After checking out DVICE’s
preview of the competitors
yesterday, we’re happy to see a prototype win instead of just a concept sketch.

It’s like the ultimate talk-only medium. Or maybe what’s more disturbing is the people who actually *follow* twitter “conversations”.In 99.44% of the cases, I can’t see a case where this needs to broadcast *anything*. It needs a host that can log it to a database, and some data analysis software to do something with the data (which is where Google is going). My neighbors, relatives, and the people in Korea don’t need to see that my freezer is fast-cycling because the basement got hot. Only I care about that. And I don’t need to waste bandwidth sending twits with this data.To be sure, I’m bashing twitter, not the sweet mod of re-using a killawatt for better purposes.What I really want is whole house monitoring. Circuit Cellar had an article a few years back about putting current sensors on the output of each breaker in a box. That’s not for everyone, but I’ve got no qualms about digging around in a fuse box (done plenty of my own re-wiring).For me the issue is the data logging. Once I proved in my head that I could design a system that would log the sensors to a database, I kinda lost interest in finishing the project. That’s a problem I know have, and as a result, I’ve coined a term of my own for it. GUP (that’s in caps), or (g)reat (u)nfinished (p)roject.To qualify for a gup you have to buy components, start laying out a board, or at least do schematics for it, and then not finish it. I’ve got several dozen of these laying around…",

The wall switches are wired to the sockets, so I plugged my television into the socket on the switch and when I leave the room I can flip it off and power down the TV, DVD player, DTV tuner, lights, etc.Then, I just plugged the lamp into an X10 and use my remote to turn the light on or off instead (which supports my laziness while watching movies better than getting up to flip off the light anyway).",

As more devices reach the market that are able to interfece between each other and allow the user to have a more intelligent control over their energy.

[rog8811] shared his
laser lighter
with us. He has gutted a zippo style lighter and inserted a blue ray laser module. The old fuel compartment houses the batteries. This is pretty cool, though it might take forever to actually light a cigarette with it. His build log is quite nice with diagrams and detailed pictures of the whole process. Our question is simple, why haven’t we seen this on a James Bond film? Too bad he couldn’t use a stronger laser, like from a laser cutter. We know they do a fine job of
cutting pizzas

Another reason was just to get it to fit.Cost to build was around $30 including the lighter.Correct on the more power, I had to weigh power to room available, the Blu-ray gives a much higher mw output per ma input ratio than IR or red.Schematic is there somewhere. I am never that happy with parallel batteries but with only 38ma/h batteries I need to do it for longevity…and it makes best use of space.As to the eye safe I would not suggest lighting a cigar with it in your mouth, it works well enough just getting it to smoke.Regards rog8811",

A decent drill press is a crucial tool for an electronics lab. We use our drill press to make holes in our own circuit boards, and tap or break traces on existing circuit boards. We’ve used a lot of tools to drill circuit boards — power drills, power drills in “drill press stands”, and high-speed rotary tools — but when we started doing projects on a schedule, it was time for something more reliable.
We first spotted the
Proxxon
TBM115/TBM220 drill press in the window of a local shop. Its tiny size and adjustable speed seemed ideal for drilling circuit boards. At $200, this is one of the pricier tools in our lab, but quality bearings and smooth drilling action aren’t cheap. Read about our experience with this tool below the break.
This drill press is tiny, less than a foot tall. It’s easy to tuck away in a closet or under a bed. Despite it’s size, it has all the typical drill press functions like adjustable height and drill depth.
An adjustable drive belt connects the drill head to the motor. The belt moves to different positions on internal pulleys to create three combinations of speed and torque; 1,800, 4,700 and 8,500 rpm. It’s a bit of a pain to adjust the belt, and the instructions for proper tightness are a bit vague.
If the drill is left for long periods, the belt should be loosened so it doesn’t warp. We think our drill press was over-tightened and stood in a hot shop window for more than a year. Now it sometimes suffers excessive vibration and noise after long periods of drilling. This was ameliorated to some extent by the previously mentioned vague adjustment procedure, but we probably need a new belt. While this is a problem specific to our drill, it’s something to consider if you have similar problems, or if you have the opportunity to buy a new belt when you get the drill.
The drill came with 6
collets
of various diameters, but no chuck. We bought the collet-compatible drill bit in the photo at the local electronics store for about $10. Reconditioned drill bits are much cheaper on eBay and we’ve also had
Drill Bit City
recommended to us.
We usually use cheap 0.8mm bits that don’t fit in a collet, so we bought the optional chuck. As you can see in the photo, after a couple years we still haven’t taken it out of the package. The drill is so smooth and straight that the first bit we purchased has lasted through two years of medium-duty use.
Proper safety is imperative when working with high-speed drills and tiny bits. You
must
wear safety glasses. Every bit will break, it’s just a question of when. A broken bit will usually stick inside the circuit board, but sometimes they shoot out like shrapnel and stick in the woodwork. Not wearing safety glasses while using a high-speed drill almost guarantees you’ll eventually lose an eye. We also wear a dust mask, not just to protect the lungs from fiberglass dust, but to shield the face from broken drill bit debris.
Like our
soldering station
, this is another tool that we absolutely love. It’s the prefect size for working with circuit boards, and worlds better than any high-speed rotary tool we’ve had the displeasure of using. The drilling action is very smooth, and the motor has tons of speed and torque. The biggest difference to us, migrating from a cordless drill on an old drill press stand, is the steadiness of the drilling head. It drills super sharp holes with no wobble or rough edges. This is one of the most important tools in our lab, and one of our favorites.
The 115volt North American model (TBM 115) is available
here
for about $200, a
search
shows several other outlets. The 220volt EU/AUS/world model (TBM 220) is available from
here
, and a number of
online shops
. You can also
contact Proxxon
to find nearby brick and mortar outlets.

The quality is OK for the price (44€ for the smallest model, 50mm quill travel), but the drill depth adjuster is a mess, the pulleys are cheap plastic, the chuck is imprecise and the belt tightening mechanism is a bad joke (the motors axle can never be perpendicular which sometimes results in a “jumping” or skipping belt). But it does its job, the question is how long. I don´t even intend to use it for pcb related work, i got a mill (with a Proxxon mill motor) for that.The Proxxon is probably better suited for miniature work on pcb, mainly because it´s more precise chuck. What the Proxxon won´t handle is huge drill diameters and much quill travel. But it is definitely a longer lasting quality machine.I´ll probably go and spend some 80€ in a precision quick-action drill chuck and this will solve some problems related to accuracy. As usual you pay more for the accessoires as for the machine itself. As i am the “buy cheap – improve it later” type i´ll also see if i can eliminate some of the other issues, like replacing the pulleys with aluminium type, getting a sturdier quill travel adjustment and improvement of the belt tightening.",

The latter combo is less expensive, can be a lot more flexible and if it works just as well, why not?I was looking at the drill presses found at Micro-Mark —http://www.micromark.com/MICROLUX-3-SPEED-MINI-DRILL-PRESS,7797.htmlhttp://www.micromark.com/MICROLUX-BENCHTOP-VARIABLE-SPEED-MINI-HOBBY-DRILL-PRESS,8283.htmlHowever, both have chucks which increase runout somewhat. They informed me that the more expensive variable speed drill press would have less than .004″ runout, and then it only goes to 5000 rpm. It’s interesting that the cheaper 3-speed unit looks SOOO similar to the Proxxon reviewed here, yet it has a chuck and does not operate at the same speeds. Hmmm…",

"content": "How to choose between the 28128/38128 drill and the 28606 drill stand + 28481 motor?1) The 28606 die-cast swivel head does not sit perfectly true, so the drill-bit will not be perfectly vertical in its descent. Hardly matters on a thin PCB, but very important with thicker, heavier work.2) The 28606 rises and falls on its column via 2 drilled holes in a thin die-casting. If they develop some wear, you will need to bush the holes. So, durability is the issue.3) The 28481/38481 actually has a tiny 232-gram 5000-20000rpm DC motor driven off a mains voltage speed controller, while the ‘real’ drill press motor is a chunky 561-gram 7450rpm AC motor and you change speeds with step pulleys. Again, durability is the issue.The 28128/38128 costs more, but is a very professional design for a specific purpose. On a lower budget, the 28606+28481/38481 is versatile (you can detach the tool for grinding, etc) but will yield lower accuracy and shorter life.My thanks to Mark at Proxxon World for the numbers. The opinions are my own.Josh",

Building your own CPU sounds like quite a daunting task as it is.
Building your own CPU using manual wire wrapping
transcends difficult to become an art form. [Steve] has built a CPU by
manually wrapping
every single wire. That’s 1253 wires, or 2506 wrapped ends. Even if it didn’t work, it would be nice to look at. But it does work, you can see a demo video showing the audio functions after the break. The system is now enclosed in an Acer x-terminal case, so it isn’t as pretty, but its still quite a project. You can follow along as he builds each section, the video, sound, even the keyboard interface. It’s pretty amazing seeing it all broken down to the most basic forms.

] |
[Jared Bouck] has been sending in his projects for a couple years now. We’ve enjoyed his
heavy-duty DDR pads
,
LCD backlight repair
, and
ion cooling projects
. His latest, an
RC paintball gun turret
, is our favorite though. He actually rates this as one of the easier projects he’s published; it just took a while to assemble. Several design decisions were made to keep the project simple. Two 32 Degrees Icon-E paintball guns were used. The guns already have electric solenoids for firing, so a special trigger mechanism didn’t have to be fashioned.
Q-loaders
were used to prevent any ball feed problems. The motors, driver boards, and RC components are all borrowed from combat robots for reliability. He’s hoping to produce a small number of kits based on this design.
Related: We’ve got quite a few
sentry gun
projects in the archive.

[Logicdustbin] sent in his
iCast project
. He gutted a blue
iMac
and inserted a DreamCast and an LCD. It looks very nice. His ports on the front seem almost factory installed. You can
follow his build on the cgcc forums
.

Or that it supported vga, also reasonable. But those aren’t the sorts of things that really make a console. As far as hackability, it was ahead of the generation-1 consoles, but was similar to the ps2, and paled in comparison to to the xbox1, which boasted an easily upgradable 8gb HDD, built-in ethernet, excellent graphics hardware, an easy to replace operating system, and an unrivaled quantity of useful home brew software (Evox XBMC dvd2xbox HCE emulators for everything up to playstation ect.)The dc’s biggest failing though was it’s games. it was supperior in a few niche genra’s like light-gun games, but but for every good dreamcast game available there are at least 5 for the xbox and n64 and maybe as many as 15 for the ps2 & ps1.Don’t get me wrong, the dc console itself isn’t bad at all, but sega really doomed it my releasing it late first generation, late enough to have to compete with the second gen consoles, yet early enough to be technically inferior to them. A consoles value is sort of like a feedback loop, the dc’s comparatively weak player base resulted in a proportionally weak game line up, which further dissuaded gamers and so on…",

"content": "Wrong again, The DC requires NO modification to boot custom software, and is infinitely easier to program for than the PS2. The only reason the xbox has more useful software is because it is more powerful, no shit your not going to see XBMC on the dreamcast. It does have some modification advantages like you said because MS basically sold a cheap PC with a custom OS, the games where fantastic though, there where some crappy ones but there where some that to this day are considered some of the best of their genres. The reason for less games is the console wasn’t out as long. There are TONS of games on the PS1 and PS2 because they where out way longer, and going by your logic I could say Yeah the PS1/PS2 was awesome but for every good game there where about 50+ shitty ones because they where pumping out/licensing like 10+ games a week. There is no way most of them are going to be that good. Again your wrong on your last points, the console didn’t come out “late first generation” (what are you like 15 judging by that statement because that would be FIFTH generation by my count) It came out EARLY for the next generation to compete with the PS2. The processing power of the DC and PS2 have also been compared time and time again with each of them coming ahead in different tests making them very comparable. The DC could for sure keep up, so no one was technically inferior. Everyone was outperformed by the Xbox though. As for your theory on why the Dreamcast failed, wrong AGAIN, This is definitely debatable but I can tell your for sure that your answer is entirely wrong, Most people agree that it was because the PS2 came out and was so huge, everyone was distracted from the Dreamcast long enough to kill it. Sony launched right away with some killer apps/big franchise titles, Sega already had theirs out so they had nothing to fight back with until it was too late. They had also failed miserably with the Sega Saturn (Have you ever even heard of it? THAT is what was meant to compete with the PS1/N64) so they weren’t in a very good situation. Although even the Saturn is a very cool console, they where just a little late to the 3D party.",

As for the xbox’s hardware, as I said, the dreamcast is only inferior because it’s older, BUT IT’S STILL INFERIOR, they cost about the same these days, but the xbox is more capable in modding terms, period. Btw, what do you mean “not out as long”? the dc came out before any of the 6th generation consoles. Did you mean “took less time to die”?As for the disparity in games, obviously we can’t argue objectively about their average quality, but that doesn’t change the fact that you’ve provided no reason for the dc’s games to be above average that wouldn’t be invalidated by the consoles differences in popularity.To be fair, you are right about the the ps2 stealing the spotlight from the dreamcast with it’s brand association. I don’t think that was the only factor in the dc demise, but that was certainly a large part.@david comeauFirst of all, despite you’re verbosity, I fail to see how loading a gamesave and copying some files via ftp is so daunting (this is had, remember)? Also, I don’t see how having a prefrence for one system or another makes me a fanboy, right now I have all the major consoles from the last three generations, and have most of the major games for each of them. The consoles each have their strengths and weaknesses, but between myself and 4 roommates, the dreamcast is the only one that doesn’t get played.Argh… arguing with an entire comment thread is tiring.

"content": "Err… You’re arguing with someone who does not feel that preferring one console over all the others and preaching about how superior it is would be defined as a fanboy. That’s… pretty much exactly what it means though. One of the other issues that no one else pointed out here (from a programmer’s perspective) was that the Dreamcast was too easy to pirate. If I could pay my licensing fee and code/release on the PS2 or the DC, I’d go with the PS2 because it was much more likely to be sold. If say 1000 people played my game on the PS2 and 1000 played it on the DC, I’d sell 990 PS2 copies (minor piracy) and maybe 40 DC copies if I was lucky as hell. Had a couple friends who DID work for game developers (not naming ’em for privacy) and that was the general opinion of ALL their programmers and company heads at the time – it was so common for everyone to simply pirate the games instead of buying a copy that the DC wasn’t economical. Yes, it was more powerful in some ways, but money talks.As a side note, you left out a huge set of categories. 2D fightinggames. DC really won on that one.Shoot-em-up vertical games. Again, DC really had a nice huge library.And best of all… RPGs. The PS2 did have a good library too, but there were so many beautifully done ones that the Dreamcast was THE console for it’s generation if you really loved RPGs. Note the development dates on the 2 as well, while both the PS2 and Dreamcast were out, the DC by far had a huge lead. Once it was ruled down to just the Xbox and PS2, the PS2 took over since there really wasn’t any alternative for programmers – again, target audience, what % of them own a system, what % are likely to buy the game. That makes the decision.Sadly, since then it’s been difficult to find a good RPG system.Wii? Xbox360? PS3? Where are all the RPGs in the US? I want my good ol’ turn based ones! (Granted, there are a few, like Oblivion for example, but it’s not console-specific, and it’s sort of… restricted. No turn-based strategy driven battles. That aside I love the game, but I still want a nice old-school Final Fantasy/Xenogears/Dragon’s Quest/Chrono Trigger/etc type game every now and then.)",

[Barney_1] built this
sereial RSS reader
. He’s using the
Dragon Rider 500
development board, which is a kit that has expansions available including the LCD, serial interface, and power supply. You don’t need the kit though, you could just build your own with similar specs. He has written a program in python to scrape RSS feeds and send them to the LCD. He’s got some specific workarounds for the Dragon Rider board if you do have one. You can download the firmware and source code on his site. You can see a video of it after the break.

"content": "I will readily grant that some people are better than others at building nifty little things. I’m pretty decent at designing microcontroller based designs, but I suck at FPGAs and analog.I’ve also been around this industry for a *long* time. Wire wrapping our own 6502, Z80, 6800 systems in the old day was the norm. I’m not impressed by people who do this today, yet some sites seem to make a big deal out of it.That said, I do have a lot of respect for people who design and implement their own CPUs, whether it’s in TTL, bitslice type processors, or FPGAs. That requires a lot more smarts than we did to take a stock Z80, etc design, and add some additional memory, I/O, or any other cookbook type technology.It seems this is a lost artform. I say “good work” to the guy who got this Python script working on a serial terminal. I’m sure he learned something.But hack-a-day worthy? Hitting every DIY website? It’s just not an impressive project. To me, it’s in the same class as making a LED blink.Have I put up or shut up? No. I build my projects, large and small, and use them. I’m terrible about documenting them. Once they work or do what I want (which is not always the same thing!), I lose interest in them.http://www.tinymicros.com/wiki/1-wire_networkHere’s something I did with Dallas 1-wire. It’s *trivial*. No rocket science, no magic, no hard thinking. And the only reason this page exists is because the OWFS group wanted examples of projects that used the OWFS. Otherwise, I wouldn’t have bothered. It’s not impressive, and barely interesting.To me, it just seems a lot of the projects that make the rounds on the DIY scene are as impressive as building your own PC (i.e., buy motherboard, memory, HD, case, and assembling them together).Impressing me takes something unique, that hasn’t been done before, or a good variation on it. Apply technology in a an unusual way or for an unusual purpose. Making an avalanche sensor out of a smoke detector and an AVR. That’d be cool! Devices that have social value, for the handicapped, 3rd world countries, etc.Should you care about impressing me? Absolutely not. My opinion doesn’t matter one iota to anyone else, nor should it. I’m just stating what it takes for me to go “wow”.",

Vacuum formers are still fairly rare in our community, so it was a surprise to see that in the 1960s Mattel
marketed one as a toy
. It used a hot plate to mold plastic sheets into various shapes. The design was updated by Toymax in the early ’90s to use a light bulb heating element to make car bodies, like some sort of manly Easy-Bake Oven. The home-built machines we’ve seen are a much larger scale. In 2005, we
posted
[Ralis Kahn]’s version that
employed an electric grill
as the heating element. [drcrash] has since built on those plans, hoping to
develop an even cheaper device
.

Here’s another nerdy present that was built for Valentine’s Day. [João Silva] created a
temperature sensing Munny
. A
Munny
is a vinyl toy made to be customized. Other than these
Munny speakers
, we haven’t seen them in many electronics projects. The LM35CZ temperature sensor has an analog output that connects to the ADC on the ATtiny15L. The microcontroller changes the RGB LED’s color based on the temperature: blue for cold, green for comfortable, and red for hot. It only flashes every three minutes to conserve the power in the coin cells. His one-off circuit board also includes an ISP header for programming. The Munny’s head looks like it does a great job diffusing the light.

Dirk’s Accident

Caleb Kraft
|
[
"News"

[
"finger",
"magnet"
] |
Warning: this link contains graphic images depicting
removal of a fingernail by giant freaking magnets
. [Dirk] likes to collect odd things. A few of those odd things, just happen to be massive Neodymium magnets. Even though he was really really careful, somehow two of them ended up close enough to attract each other. After a brief flight, the two collided with his finger tip in between them. It is probably still there now.
We know these things can be pretty dangerous and usually warn people when doing projects that require them, like
building a wind turbine
.

"content": "Wow, somebody else who’s had magnets stuck on their penis!They were the little round ones used for weak magnetic earings, maybe 5mmx1mm. Almost no force to speak of until you get them 5mm apart from each other. It was fun. Until you discover that the very top of the perineal raphe, right below the corona, is a fold of skin with lots of nerve endings and no fat – so it compresses from about 2mm thick to about 1/2mm thick under any force, and with a magnet that packs about a pound of pressure into a tiny package at that distance, it pulls the skin around so hard, and makes it so swollen, that it almost gets lost.It took me an hour of suppressing screams, pushing them apart off only to have them snap back again, and wondering how I’d ever live with myself if I sought help, before I finally got it off. Part of the problem with needlenose pliers was that whenever they got close, they rapidly gained force and stabbed me. There is really nothing you can do to get leverage on both sides in order to control the pliers without piercing yourself by squeezing the magnets together. I’m reasonably sure if I’d stopped trying for a few hours I would have a permanent piercing there.Geek Dads – welcome to Things You Can’t Forsee to Protect Your Kids From.

[Andrew] sent us this great breakdown of an
LCD monitor repair
. After his wife’s monitor developed an issue with rippling in the picture, he was forced to decide between trashing it, or fixing it. He decided for the latter, possibly to his wife’s disappointment. The rippling image could easily be attributed to a failed filter in the power supply. Knowing that
capacitors are a prime suspect in these cases
, he tore in, looking for failures. He found that there were, in fact, 2 bad capacitors on the back light circuit. After replacing them with newer, higher quality ones, the monitor was as good as new.

I have done this a bunch, you could make a lot of money by affiliating yourself with a salvage business and repairing the monitors they have.On ebay you can get nice PC monitors for $50-75 (less shipping, which will add $30-50), if you could get ahold of those and fix them to sell for twice as much and split the profit with the outfit it might be a business case ;).I personally bought 2 Hitachi and a Planar (same product rebranded), and swapped parts into 2 working ones. Saving the extra parts I was able to replace the starting capacitors that burned out on a customer’s LCD.I wish that repair of things was more common (oh that? just junk it!), like the recommendation to throw away a PSU because the fan quit. I don’t, I solder in a new fan and keep on trucking. It is cheaper and more environmentally conscientious.",

They either don’t have electrolyte or have the wrong sort. They die fast. A lot of power supplies for computers and monitors used these for filtering. The ones I’ve been replacing, I didn’t even have to check: the top, which should be flat enough to reflect a spot of light, was puffed upwards like a dome.Most caps used in commercial/consumer goods are only rated to 20% accuracy or even worse, so your 33uF cap might measure 25uF and still be good, or at least as good as it ever was. I’ve seen plenty of caps sold 50% out of spec.Sanyo Oscon caps don’t have electrolyte. They have amazing lifetimes, as a result. They’re expensive, but if you want something to last, they’re a good investment. If you don’t want to spend that kind of money, any cap that a place like Digikey sells will give you a reasonable reliability, and better than the no-name or unheard-of caps that most modern equipment uses.",

The local repair shops generally lack the reverse engineering skills that are required to repair most electronic problems. Secondly if they can repair a device they charge far too much for the time and parts (which usually superceeds the device replacement price)This is a sad fact of our times.To cite an example i recently bought a bad Toshiba 48″ DLP HD TV for a price i could not turn down. Turns out the tv did not have any audio. After tearing in to the TV i found plenty of evidence that someone had tried to repair the TV. They snapped of a FPC lock (never hooked it up) busted off frame mounts, etc. After tearing the unit down hoping to find the FPC lock, i did find it and attached the FPC back to the daughter AV board. Suddenly i had noise in the speaker at high volumes but still no audio. From here i used some common sense. #1, The speakers still make sound so they are ok, The amplifier still work since it was driving the speakers. The digital volume control still worked since i could adjust the volume to a level of which i could hear noise. Most likely the only thing left is the MUX. I already knew where the mux was by looking at the numerous audio traces running back to a single chip. Turns out that the 11:3 I2C analog mux is fried, all inputs and outputs have 5vdc (checked the 5vdc power pins, they are fine) I suspect static or lightning damage.At any rate the DLP HD TV was bought and repaired for < $60.",

Very few businesses charge “far too much” if they can help it, because it makes them noncompetitive and drives away customers. So if all of them are asking “too much” you should probably adjust your expectations instead of complaining about their cost.Seriously though, make a list of all the monthly running costs and upfront investment you’d have before you’ve even desoldered a single cap. Then make a realistic estimate of how many customers you’re going to have and how much time you need to fix unknown devices without board schematics. I think you’ll find most local repair shops are quite cheap in terms of labour rates. The owners gotta eat too.",

Hobby electronics manufacturer SparkFun has started offering
various classes
at their Boulder, CO facility. [Landon] has been attending as many as possible and posted about his
experience during their Stencil and Solder Paste class
. Solder paste is used when manufacturing boards with a reflow oven. He took quite a few pictures of the process and posted notes and audio. He says it’s definitely something you’d have to learn hands-on, but his numerous photos give you an idea of what’s involved. Below, you can watch a video of the paste clean-up pass and stencil removal.

The problem with stenciling paste is that if you are only doing one or two chips at a time, why hassle with stenciling since a nice soldering iron will do the same? The stencils cost money ($99 I believe), the paste is expensive (~$50) and goes bad after a few months (even in the fridge). If you are doing a multiple part board stuff then by the time you hand place all the components you will find that the paste has dried out and does not reflow well or at all. The only way I consider using paste stencils is with a pick and place machine or if you have a big panel of boards with only a few parts on each. I’ve stuffed plenty of 100+ component boards with all 0402 and QFN parts using a soldering iron without trouble.",

Hackit: Hackable Bluetooth Bracelet?

We spotted this odd piece of geek couture
on DVICE today
. It’s a bracelet that
displays incoming calls via Bluetooth
and also vibrates. The intended use is kinda interesting, but we wonder what else could be done with it. Could you update it with any text you want by creating fake caller ID messages? You could have your
laptop
in your backpack and have the bracelet update when it finds an open access point or any other sort of notification. The display shows the word “Connecting” in pictures, but apparently only displays numbers for incoming calls. It also includes a button to reject calls.
Do you have a project that needs a wireless display? Are there other options like this? At $25, this might be worth a try.

Now I just realized most were not in reply to my post. oh well, here are my responses because i care and take criticism well apparently. I want to share what i know because i have some good ideas and no time to work on stuff like this, so i like to see others do it. it’s why i love this site. i know i could easily learn to do the menial stuff like soldering. i can solder but not well. i have a solid ee background though because it was my father’s career choice, so the knowledge is here, trust me. i won’t say something unless i’m sure of it.so, mainly i think the questions were about how i would accomplish “displaying whatever i want”, that was directly quoted. anyway, my background is basically how. i’d use the components to learn to build something. i said I “know” because i was in an overly confident mood last night. i meant i know i have that capability, not that it’s necessarily possible with a proprietary undocumented controller. I think with enough examination it would be, probably an oscilloscope would be needed. i think my dad has an old one somewhere. so that’s why i said i know. sorry if you mistook it. any questions i’ll tell you what i think and can probably give you an idea of how to accomplish it.oh and someone said it’d be hard to work in a dick tracy mode. i agree. i was just saying i could probably manage it somehow. worst case it would be a ton of work to examine it, but chances are the controller is documented, i’ve never done this myself but i’ve studied it and it seems like in most cases the manufacturer is willing to share the necessary information. glad the ee community mostly seems to be about sharing knowledge.",

I think you’re right in that HSP to my knowledge doesn’t support callerID, but it probably supports that profile due to the lower-end model, which doesn’t have a screen. I imagine they’re similar hardware – in fact, the package I got actually had a picture of the screenless model on it instead. (It was packaged nicely, by the way).@fartface:Your post barely deserves a reply, but for the sake of others, I will. I have the device on my wrist right now, and it’s actually built quite well. It’s not perfect, but it’s better than I expected for the money. The metal parts are supposedly steel (not sure), and the band is some rubbery material, similar to some watch straps, but thicker. As for the so-called “epic fail”, I saw the comment you’re referring to, and if it’s even true, then it isn’t a problem for me. You see, HSP/HFP support switching audio to the handset. On a headset, this is normally done manually; on the bracelet, you can accept/reject the call manually, or you can just flip/slide open your phone, and it automagically switches audio to the handset. Please check your facts next time.",

If I could afford it I would buy this and see if I could do the same, I probably could.Having the capability to make it vibrate at will, it could be used for a variety of things like e-mail notification, server problems, irc private messages etc. Without the LCD, you could differentiate between them by make it vibrate a certain amount of times.",

Mac Mini In An Old Apple II Disk Drive

Yo dawg, we heard you liked macs. [Charles] got sick of his Mac mini looking nice and pretty and decided to
cram it into an old beige box
. This old beige box just happened to be an old Apple II disk drive, so we guess that gives it some more street cred. The original disk drive sold in 1978 for $500. Man times have changed.
[thanks BluRy]

The $10 “fire-starter” is the most common beginner soldering iron. These are simple irons with a hot end, a handle, and little else. There’s no temperature control or indication. Despite their simplicity, they’ll do just about anything. You can solder any legged chip type with this type of iron. We used fire-starters in the lab for years.
Eventually, we wanted a hot air rework tool to salvage SMD parts and solder QFN chips. Aoyue is a relatively unknown Chinese brand that makes soldering stations very similar in appearance and function to
Hakko
. Aoyue stations are
recommended
and used
by Sparkfun Electronics, something that factored heavily in our decision to buy an Aoyue. Read more about our experiences with this tool after the break.
The Aoyue 968 combines three tools: an adjustable soldering iron, a digitally controlled hot air tool, and a fume extractor. We usually prefer separate units because the parts can be individually upgraded or replaced, but this combined tool is much cheaper and saves valuable bench space in the lab.
The soldering iron temperature is adjusted with a knob, with a range of 200 to 480 degrees Celsius. We usually solder between 300C and 350C.
The iron handle is an inexpensive plastic assembly that eventually broke along the threads that hold the iron in place.
New irons
are available for around $15, but we fixed the old one with some high-temperature epoxy.
The fume extractor is a tube that attaches to the soldering iron. The hot air rework tool air intake is used to suck fumes away from the tip of the iron. The fumes are filtered with a small plastic net before exiting through the hot-air tool. It works really well, and eliminates the breath-hold-solder-breath system we used to avoid getting a nose full of flux fumes. The tiny filter doesn’t look like it does much, but it came with a replacement. We worry somewhat about the long term effects of coating the hot air tool’s heating element with rosin and other crud.
It’s pretty obvious that the iron holder wasn’t intended for this particular iron because the holding ring doesn’t fit the fume extractor attachment, this is a bit of a pain.
The hot air rework tool has a temperature range of 90 to 480 degrees Celsius. We use 400C hot air to remove passive parts, and 420C to remove chips.
The temperature is adjusted in 2 degree increments using the digital numerical readouts. The air flow rate is adjusted with a knob, volume is indicated by a floating ball gauge. The hot air tool came with a half-dozen nozzles, we’ve only used the medium size.
We’re extremely happy with the Auyoe 968. It’s already paid for itself twice, in terms of not having to replace $10 soldering irons every month. If it breaks, we can buy a new one without regret. The hot air rework tool has opened a world of possibilities for salvaging parts and repairing projects. The adjustable soldering iron provides enough heat to solder something big and dirty, but also adjusts downward so it doesn’t destroy delicate traces. We haven’t needed to replace the iron tip or either heating element, but we understand they’re compatible with parts from other major manufacturers .
Until recently, Auyoe was only available in Asia and Europe. We bought this one in Germany for about $100. The Aoyue 968 is now available on
Amazon
in North America,
Sparkfun
also has several other Aoyue models.
Sure, Aoyue isn’t haute couture for geeks like a
Hakko
or
Weller
, but for less than a third of the price you get a respectable rework station that’s not a lifetime investment. As heavy DIY users, we think this station has performed great. We highly recommend it to anyone buying their first serious soldering iron. If you’re a pro with an industrial budget, buy yourself a Hakko or Weller; we’re doing just fine with our Aoyue!

"content": "I’ve had mine for at least a year or so for light soldering and occasionally rework and its great. The holder is mildly annoying but you can get the air extractor to fit outside the ring and the soldering part in the middle.The one thing you might want to mention is the filter is NOISEY, i mean its not too bad, but after its been on awhile and you turn it off its always that ‘ahhh so much better’ relief feeling. So if you used it a lot, might want to consider that. BUT, its much better having it than not. The amount of fume reduction is huge.The heat gun is also quite useful. My only other wish is that it was a desoldering station as well :P",

Got mine for ~£100 sterling in a Maplin sale (just before they stopped selling them) and it’s lasted somewhere on the order of five years. The only fault it’s picked up along the way is a slight buzz (I think the transformer laminations have come loose).The 852 is very nice, for what it cost. I’ve spent about an hour using it, and managed to remove some SMDs from an old mobile phone PCB quite easily. Truth be told, I bought it for SMD rework and because I wanted to have a go at QFN soldering (there’s an Intersil appnote about doing this with a soldering iron and a hot air station).Got my 852A+ from here —http://www.pcb-soldering.co.uk/index.php?target=products&product_id=37.

[Chris] sent us this project, where he built a
tiny supercomputer called the Non-von1
. Wanting a supercomputer, but lacking space and funds, he opted to go after the supercomputers of the 80s. His system was patterned after the “
Von Neumann
” systems developed at Columbia university. His system has 31 8 bit processors to crunch numbers for him. The whole unit communicates with the computer using a19.2 kbps serial link. He does talk about its limited capabilities, stating that he could use it as a way to store roughly half of his cell phone’s phonebook. This reminds us of the
Basic stamp supercomputer
we covered back in November.

[Peter] found that Polaroid film was an easy medium to play with, as the ability to develop it is built in. He has done several fun experiments, from
electrocuting it to making giant mozaics
. The Polaroid film may not be easy to get your hands on though. They stopped producing it in the summer of 2008. Some
former employees are trying hard to get it back into production
, but that may never happen. Polaroid has
recently received permission to sell itself at auction
. We’ll just have to wait and see.

If you’re into robotics, you’re probably already familiar with the 2 motor walker. This design, usually used in
B.E.A.M. robotics
is a pretty easy way to make a 4 legged walking robot. [Edwindertien] has made the design a little bit easier to build with these
flatpack walker plans
. He used 4mm thick birch, cut by laser to get his walker into shape, but the design would work with almost any material. His walker is Arduino powered, so it could be
programmed for all kinds of behavior
, especially if you add some sensors. You can see his bot in action after the break.

We love keeping track of new interaction technologies and this new touchscreen by Stantum looks especially promising. Engadget shot a
hands-on video with it
at the Mobile World Conference. It’s a resistive screen, so it can be used with both fingers and styluses (unlike capacitive screens). It’s sensitive enough that you could use a brush too. The screen supports any number of
multitouch
points and does pressure sensing based on the size of the detected fingertip. The touch detection is actually more accurate than the screen can display. Stantum is hoping mobile manufactures will pick up their input framework for inclusion in new devices. The resistive touchscreen was built to Stantum’s specifications (it won’t work with current phones), but they say it wouldn’t be hard to go into mass production.

Segway And Input Filtering

[Kerry] is
building a segway type vehicle
for a senior project. Though it doesn’t appear to be done yet, there is some good work finished. As with any balancing bot, it relies heavily on input from a gyroscope, and at least in this case, an accelerometer. That data can be very messy. The sensitivity of the sensor means that people often end up with vibrating or drifting in their projects. [Kerry] has put some work into finding a method of smoothing that results in fast, accurate, but smooth reaction. You can see a video of some comparisons between methods after the break.

Bristle Bot Controversy

When the
Bristlebots
were released back in 2007 by Evil Mad Scientist Laboratories, we all thought they were pretty cool. Apparently someone at Klutz did too. They have released a book, with the title “Invasion of the BristleBots”. The bots seem to be identical and the name is identical. There is no mention of Evil Mad Scientist Laboratories anywhere in it.
[Phillip Torrone] has attempted to contact Klutz and the book publisher Scholastic
directly to find out more information.
[Windell] and [Lenore] from EMSL had this to say:
“This is the first that I’ve heard of it. Frankly, I am a bit offended. Klutz makes some nice things, and I’m surprised that they wouldn’t have contacted us, asked permission, or at least given us credit. (Locomotion by ratcheting bristles isn’t remotely new — it occurs in nature — but the name ‘Bristlebot’ is surely ours, and I don’t know of any prior implementation with a toothbrush.)”
You probably know EMSL from their other projects such as the
Peggy
and
Meggy jr
. How would you feel if a project you did was published without credit? Would you care or not?

Did a google search and found a company have made a wireless camera for bows so hunters can record their adventures, but nobody else has thought of using it as a sight setup with LCD glasses. If someone went ahead and made money off that idea then that would be cool because I don’t have the resources to setup such a venture. I would be somewhat pissed if someone clearly ripped off an original idea I came up with.Anyway this bristle bot thing is a clear rip-off of evil mad scientist’s idea and Klutz deserve all the flak they get for not acknowledging the source of their new revenue stream.",

The fact that Evil Mad put it out there on the internet with that name long before Klutz’ book is a bit suspect.Legally, Klutz is in the clear, but ethically, they screwed up IMHO.The sad thing is that a book that inspires children toward building electronic devices could have benefited greatly from a link to Evil Mad’s website. This would have given those reading the book a place to go to find even more cool electronics projects.At this point, the only recourse any of us, who post projects, hacks or new ideas online, have against a company turning a profit on our ideas is shame. I say call out companies who do this and shame them into being more careful to give credit where credit is due.",

Cell Phone Triggered Fireworks

[Mr. Hasselhoff] is
using a disposable cell phone to trigger his fireworks
. He has wired into the speaker leads for the speaker phone. When the phone rings, the current sets off a
thyristor
allowing for a battery pack to be discharged into a rocket fuse. These fuses heat up and ignite, so you can use them to light fireworks fuses pretty easily. This is pretty simple and cheap, considering the price of the cell phone was only $10. His next idea was to have it recognize dial tones and set individual fuses off, but that would require a microcontroller and a much more complex hack. At that point, you might as well just build a
fully fledged wireless fireworks launching system
and possibly
add rocket launching abilities too
.

Always. Is this particularly dangerous? Well, that obviously depends on *what* you are igniting, but for anything you can legally purchase I guarantee it’s safer than lighting a five inch fuse with a match.Think before you whine.",

When we first saw
[Chris Paget]’s cloning video
, our reaction was pretty ‘meh’. We’d seen RFID cloning before and the
Mifare crack
was probably the last time RFID was actually interesting. His ShmooCon presentation, embedded above, caught us completely off-guard. It’s very informative; we highly recommend it.
The hardest part about selling this talk is that it has to use two overloaded words: ‘RFID’ and ‘passport’. The Passport Card, which is part the the
Western Hemisphere Travel Initiative
(WHTI), is not like the passport book that you’re familiar with. It has the form factor of a driver’s license and can only be used for land and sea travel between the USA, Canada, the Caribbean region, Bermuda, and Mexico. They’ve only started issuing them this year.
The Passport Card also uses RFID… but not the same technology as e-passports that have been issued world wide. You’re probably familiar with 125KHz access control cards and 13.56MHz smartcards, MiFare tags, and e-passports. These are all inductively coupled technologies. The RFID used in Passport Cards is in the 900MHz band and is a capacitive technology. It’s EPC Class 1 Generation 2, the same sort of technology used to track goods in warehouses. Each EPC has a 96bit ID number. By design, they have to be readable from a minimum of 30 feet.
To start his research, [Chris] purchased an XR400 RFID reader of off eBay. This is an industrial reader with four antenna ports and Windows CE. He got a great deal… because it didn’t work. He guessed that the ball grid array (BGA) solder joints had cracked. Putting enough pressure on the chips allowed the device to boot. He repaired the board using a heat gun to reflow the solder. He referenced this video of an
Xbox 360 being repaired with the same technique
. [bunnie] has a post from last year
investigating Xbox 360 RRODs
and possible BGA failures.
900MHz RFID cards are not inductively coupled to the reader, so their read range is not limited by the wavelength. With a HAM license in the US, you can broadcast with up to 1500W. At Defcon this year, [Chris] plans on going for a new read record. He cited the company
ThingMagic
using 10W into a 12dbi antenna and getting 100% read reliability from 213ft. The theoretical limit for 1500W through a 18dBi antenna is 2.35 miles; you’d be limited by how far the tag can transmit though. He’s set up the site
RFIDHackers.com
to help coordinate efforts.
Another future project is using the
GNU Radio USRP board
to do differential power analysis against the Passport Card. It’s a brute force method for extracting the 32bit kill and lock codes for the tags, which could then be used to deactivate cards.
The goal of [Chris]’ research from the beginning was to show that RFID is unsuitable for security situations like this. Passport Cards assign a unique identifier to each holder. This ID can be read from a distance and coordinated with the holders other RFID items like their credit card. Any party can track someone holding these cards, and they don’t make border crossings any faster, since the cards still have to be checked in person.
The USA is now tracking its residents with the same respect given to items in Walmart.

The first day of The Pirate Bay’s trial has concluded. The prosecution, representing many large media companies, is attempting to prove that the defendants are directly responsible for copyright infringement. The members of The Pirate Bay are treating the trial as a
reality TV farce
. From
TorrentFreak’s coverage
, it sounds like it’s off to a great start: “For several minutes, listeners of the live audio could hear mouse-clicks as Roswall [the prosecutor -Ed.], who earlier claimed to be an expert on computer crimes, tried to get his PowerPoint presentation on the screen.”

Problem is some people wouldn’t pay a penny for a recording if they could get for free somehow. This needs to be solved somehow, unless access to the internet by the everyday citizen is curtailed. Don’t think for a moment that couldn’t happen,the corporate world owns most of the infrastructure, not the government. I expect a surcharge to be applied to products than can download, play, store digital music. That means I’ll pay for others “free” music. On the event you download, move closer to your monitor, so we can reach through and wring your neck. :) Trying to excuse one’s own ripping off of the artist, by pointing to the industry’s history of ripping off the artists, sounds a stupid as it is. None of that to say the recording industry needs to adapt to the new technology, but the problem of people unwilling to pay another for their work, if they can get it for free remains.",

Hackers are much more important to the progression of mankind and technology than any corporate rule. hackers of any kind make our world a better place (if not more interesting at least) by finding a problem or challenge presented by everyday life and trying to find a better way to solve it. even computer hackers improve the world electronically (though some do this in less than agreeable or preferable methods)black hats try to outsmart anti-virus and firewall programs while white hats produce more effective and secure anti-virus and firewall programs. the war of opposing sides that plays out like a terrible chess game spawns new ideas and methodologies. if hackers didn’t at one time wonder what would happen if they put in someone else’s bank account number we wouldn’t have account verification software or pin numbers. if nobody ever tried to forge a signature we wouldn’t have fingerprint identification. if we blame hackers for anything it should be their constant lust for a more secure and freedom filled future for all of our children and grandchildren. i will always and for ever be proud of those creative, devious, blessed, and twisted individuals who push everyone to think outside the box.",

[Knut Karlsen] put together a prototype set of
solar rechargeable batteries
. He always seemed to have batteries laying around on his worktable and figured they might as well be charging. The flexible solar cells were given to him by researchers at the
IFE
and are rated at 1.8V. He used superglue to secure them to the C cells. A silver conductive pen plus flat wires from a Canon lens connect the solar cells to the battery terminals. The batteries just trickle charge for now, but he’s going to try to build cells with built in charge controllers in the future.

firstly, we don’t know why they are doing this, and we don’t care. You are watching an
LED panel, controlled by molten metal
. The panel has the leads sticking down below the bottom of the board, so the metal can make connections as it flows past. They are using
Wood’s metal
, not mercury so it has to be heated to about 159 degrees Fahrenheit to be fluid. This has been representing problems as the metal tends to stick to whatever container he is holding it in. That actually seems to be what most of the writeup and discussion are about, rather than, what it will be used for.
[Thanks Andre]

The
DS1807
contains two logarithmic
digital potentiometers
(pots) for audio volume adjustment. Each pot has 64 volume levels plus a mute setting. The volume level of each pot is set over a two-wire
I2C
serial interface. We’ll show you how to connect and interface the DS1807 below.

We connected the DS1807 to the
Bus Pirate universal serial interface tool
as shown in the table, the same basic principals apply to any custom configuration. We used the Bus Pirate’s 5volt power supply, but the DS1807 will also work at 3.3volts. I2C requires a
pull-up resistor
on each signal line, we used the Bus Pirate’s on-board resistors connected to the on-board 5volt power supply.
Connect the DS1807 to an audio source as shown on page 3 of the datasheet. Connect the raw audio signal to the H pin and connect the L pin to ground, the attenuated audio signal will come from the W pin.
Interfacing
First, setup the Bus Pirate for I2C mode, and activate the 5volt power supply. We covered this procedure in our
last parts post
.
I2C>v
<–voltage monitor
9xx VOLTAGE MONITOR: 5V: 4.9 | 3.3V: 0.0 | VPULLUP: 5.0 |
I2C>
With the power supply configured, check the voltage monitor (v) to be sure the 5volt supply is active and that 5volts is present at the pull-up resistors.

I2C>(1)
<–run address search
xxx Searching 7bit I2C address space.
Found devices at:
0x50 0x51 0x52
<–potential addresses
I2C>
The Bus Pirate’s address search macro is a quick way to locate I2C devices without looking at the datasheet. 0x50 is an I2C write address because the last bit is 0, 0x51 is read address (last bit 1). 0x52 is probably a group/global write address because it doesn’t have a corresponding read address.
We could also determine the address from the datasheet: the base address is 0101 plus the three address select bits (A0-2, all grounded, 000) and the write or read bit (0 or 1) gives 0b01010000 (0x50).
I2C>[0x51 r r]
<–read pot values

230 I2C READ: 0x3F
<–pot0
230 I2C READ: 0x3F
<–pot1
240 I2C STOP CONDITION
I2C>
First, we read the potentiometer values at startup. [ issues the I2C start condition, 0x51 is the device read address, “r r” reads two bytes, and ] issues the I2C stop command. The default startup value is 63 (0x3f), one position above mute (datasheet page 2).

230 I2C READ: 0x00
<–pot0 value
230 I2C READ: 0x40
<–pot1 value
240 I2C STOP CONDITION
I2C>
Next, we update each volume pot with a separate command. 0x50 is the DS1807 write address, 0b10101001 (0xA9) is the command to update pot0, and 0 sets the volume to full. The next sequence uses the update pot1 command, 0b10101010 (0xaa), and sets the volume to mute (64, 0x40). Finally, we use the read procedure to verify that the values are correct.
I2C>[0x50 0xA9 64 0]
<–write both pot values
210 I2C START CONDITION
220 I2C WRITE: 0x50 GOT ACK: YES
220 I2C WRITE: 0xA9 GOT ACK: YES
<–update pot0 command
220 I2C WRITE: 0x40 GOT ACK: YES
<–pot0 value
220 I2C WRITE: 0x00 GOT ACK: YES
<–pot1 value
240 I2C STOP CONDITION
I2C>[0x51 r r]
<–read back values
210 I2C START CONDITION
220 I2C WRITE: 0x51 GOT ACK: YES
230 I2C READ: 0x40
<–pot0 value
230 I2C READ: 0x00
<–pot1 value
240 I2C STOP CONDITION
I2C>
The pot 0 write command can also be used to set both potentiometer values with a single command. Use the pot0 update command (0b10101001, 0xA9), and send the pot1 value (0) following the pot0 value (64).
I2C>[0x50 0b10101111 0x20]
<–update both pots with the same value
210 I2C START CONDITION
220 I2C WRITE: 0x50 GOT ACK: YES
220 I2C WRITE: 0xAF GOT ACK: YES
<–dual update command
220 I2C WRITE: 0x20 GOT ACK: YES
<–value to set
240 I2C STOP CONDITION
I2C>[0x51 r r]
<–read back values
210 I2C START CONDITION
220 I2C WRITE: 0x51 GOT ACK: YES
230 I2C READ: 0x20
<–pot0 value
230 I2C READ: 0x20
<–pot1 value
240 I2C STOP CONDITION
I2C>
Finally, 0xAF (0b10101111) can be used to update both potentiometers with the same value. This is probably the most useful command for stereo audio volume control where both channels have the same value and change simultaneously.
Are there any chips or components you’d like us to cover in future

Though the inspiration was said to have come from a clip of The
Young Ones
, we all know this was bound to happen eventually. [lemonie] has turned a
VHS deck into a toaster
. They’ve done a fantastic job, it looks almost perfectly stock. We can imagine that maintaining the look of the VCR was pretty difficult especially getting everything to line up correctly. Finally, we have a use for our old VHS deck. You can see a video of it in action after the break.

Facebook’s internal valuation was revealed this week thanks to
shoddy PDF redaction
. Court documents from a settlement between Facebook and
ConnectU
showed that Facebook values itself at $3.7 billion, much less than the $15 billion that was speculated during the Microsoft investment. The
AP uncovered this
by cutting and pasting from the redacted court document. It’s the same thing we showed in
our PDF redaction screencast
last summer… and it will never cease to be funny.

Twitter was flooded this morning with users posting “Don’t Click:
http://tinyurl.com/amgzs6”
;. TinyURL has since
terminated the URL
. The
original page
doesn’t seem to be live either. It displayed a button that said “Don’t Click”. If the user happened to be logged into Twitter, it would automatically update their status. The instigator partially describes the method
on his blog
(
translated
). The page would load the user’s Twitter page in an invisible iframe. The status would be pasted in and the “Don’t Click” button is placed on top of the update button. You can find the
code snippets here
and the original author
credits this post
for the inspiration. Twitter has since
added a JavaScript fragment
to each page to break out of iframes.

"content": "This is a fairly standard hack. It takes advantage of the idea that if you log into twitter, your browser has a session open with access on it. Given that plus twitter’s update methodology accepting an “HTTP GET” to do the update, its pretty easy.You can do something like this on virtually any site where you control one page and have users coming to that page that you can assume are also going to be logged in somewhere else and that “somewhere else” accepts a pure “GET” without any way to verify where it comes from.His use of an invisible iframe is not the best choice. I did a demo of this for a friend’s site to help him tighten up, and I used a layer (div) which was hidden, and had a zindex value lower than another which was in front of it. I used the url of an update (like twitter’s status update) on his site in an image tag for the background image of that layer, and a valid image in the foreground — so that if the background layer was “broken” it wouldn’t should an error. The browser saw a broken background image below a perfectly good foreground one.Its a difficult hack to protect against for a popular site. they have to track your activity or the source of the update link. Requiring a parameter on the update url which is generated on the site based on a salted hash of the user’s login name is one way to do it.",

Impress: Tactile Interface

] |
Touch screen interfaces are generally hard and flat.
Impress
tries to break from that tradition by making the display flexible. Allowing you to feel more like you are interacting with the display. In the image above, the circles seem to physically fall into the dent made by your fingers. Another application shows some rudimentary 3d modeling being done by physically pushing on the vertexes. This prototype is very interesting, we’d love to see much higher resolution on the input side of things. It states that it does pressure sensitivity, but we weren’t able to distinguish it in the video. Maybe you can, catch the video after the break. Maybe laying
one of these
on some foam would be another alternative.

They would likely be able to maintain or improve force sensitivity accuracy by mounting the sensors around the edges of the fabric. This new model would also likely allow for upward motions such as pinching and grabbing.Most importantly, switching to rear projection would allow the user to have a more obvious view of the way they’re affecting the image. The front projection made it difficult to see how the image was being warped because there was so much overlap with the user’s hands.",

[dark sponge] decided to make his DS lite, solar powered. Or, at least
charged via solar panels
. He was able to find solar cells that were 60×60 mm, which means he could fit 4 of them on the outside of the DS. This gives him a total of 6V at 80 mA output. These panels charge the battery between uses. The DS has to be open and laying on its face for all 4 panels to be exposed, but this way of mounting them didn’t alter the pocket-ability of the unit. He says he’s been using it for a while and hasn’t had to plug it in yet, but we have concerns about wiring the panels directly to the battery. As [cyrozap] points out in the comments on the instructable, this is a Lithium Ion battery, shouldn’t there be some charging circuitry involved?

The “circuitry” can be in the pack, but often the thermistor sends a signal back to the laptop or device to let it control the charge.Regardless, I don’t think even in full light that you’d see destructive over-heating from this kind of charging scheme.

It may still work, but that would require a bit more testingProbably the best option would be to cannibalize the slow li-ion charger from one of those solar charging widgets that have a battery built in. They’re designed to slowly charge an internal battery and later discharge it through the charging circuit of whatever you want to power up. Wiring the charger output from one of these straight to the DS battery would probably provide a lasting solution.",

I’m the person who made this Instructable, and I have some things to say.First of all, thanks to whoever put this on Hack a Day!I’m pretty sure the charging circuit is built into the battery. I’ve used it for a while with the backlight fully on and never had to charge it. The battery has not exploded.The 8.11 volts you saw on the multimeter was in full sunlight in the middle of the day. It’s never been that bright when I charge the DS.I have already considered using a 5v regulator, and to do that I would have to wire all of the cells in series to get a high enough voltage for it. with the panels in series, it only produces a maximum of 30 ma. put that through a 5v regulator, and you end up with even less. I would be left with so little current it could probably barely power the charging led, ending up with next to nothing for the battery.When there is no light hitting the panels, the battery will not discharge into them because I used a blocking diode on each panel.",

"content": "sooo… lots of questions regarding battery protection. Time to clarify some things… Li-ion batteries need essentially the same protection as li-polys. Most chips that are designed to protect one are also designed to protect the other. Depending on how fancy of a chip you get – they’ll protect against these things (among others): over-voltage, under-voltage, over-current, over-temperature, and cell balancing. Laptop battery protection circuits typically protect against all of those.This circuitry is built into some packs, not others. I’ve yet to see a modern laptop battery pack without this circuitry. I’ve never seen a cell phone battery with a built in protection circuit. Typically they have a built in temperature sensor – hence the three terminals that most cell phone batteries have. I’ve never taken apart a DS battery – but I highly doubt they have built in protection circuitry. Not in that form factor. No way.OK with that out of the way – how do you typically charge li-ion or li-poly batteries? Well – most circuits give them a constant current with a voltage limit. Most packs can handle 1C or higher. So what this means is that you start out charging at your set current but as the pack gets full its voltage approaches the voltage limit and the charge current slowly tapers off.Now – this guy’s circuit just connects a current source to the terminals of the battery pack. It is a weak current source, but it still is a current source. This means that he is in fact overcharging his cells, albeit slowly. Will they explode? I bet if you left it out in the sun on a hot day the pack would puff up. He’s certainly doing damage to the pack – but how much is just too hard to say.",

I also might consider a fold-out design of home-made modules (from broken ones, of course) to provide more power than needed, using some charge controlling and blocking diodes to account for other issues that might come up… but that’s not exactly super-portable like the EEE PC intends to be.",

I have a DS that works fine but will not charge the battery. I have to charge it in another DS when it dies. I opened the faulty DS up last night to see if there was a bad solder joint or other obvious damage. If you look at the mobo where the charging port is, you can see the positive lead of the charging port connects to the F1 (or was it F2? it’s not in front of me now) fuse which in turn connects to an array of resistors, transistors, and diodes, before making it’s way to the positive terminal of the battery compartment. I can only presume this is a charging circuit. So when you plug in your charger, you are not just wiring your 5.3VDC directly to your battery. I agree with the comments above that it probably won’t cause an EXPLOSION at 80ma, but it seems Nintendo has put a charging/protective circuit in there for a reason. I didn’t read the instructable to see where the hacker connected the output voltage of the solar panels. If he connected them directly to the motherboard on the line side of the charging circuit, he should have no troubles. If he wired them directly to the battery terminals then I would say he will slowly but surely overcharge the battery, shortening its useful life. Either way, great hack sir!",

Here is a cool little toy, an LED matchstick. We don’t really know what purpose it serves, but [dhananjaygadre] did a pretty good job of reproducing the effect. The light is controlled by a microprocessor to emulate the flickering of a flame. It holds a charge for a short while, staying lit for an amount of time comparable to a match. To turn it on, you even “strike” it on a match box filled with magnets.

Sometimes you absolutely need to keep your phone a secret. You know, like when you’re on spy missions. The goons at the door will always frisk you, but they never check under your shoe, right? [mikeyberman] shows us how to make our own
Maxwell Smart style shoe phone
. All you need is to dig a giant hole in your shoe sole and cram a cell phone in there. Will it get ruined by water? Probably. Will you look like a goon trying to talk on it? Definitely. Can you make it through airport security? Try it and let us know.

The
Remote Exploit Development Team
has just
announced BackTrack 4 Beta
. BackTrack is a Linux based LiveCD intended for security testing and we’ve been watching the project since the very early days. They say this new beta is both stable and usable. They’ve moved towards behaving like an actual distribution: it’s based on Debian core, they use Ubuntu software, and they’re running their own BackTrack repositories for future updates. There are a lot of new features, but the one we’re most interested in is the built in
Pico
card support. You can use the
FPGA
s to generate rainbow tables and do lookups for things like WPA,
GSM
, and Bluetooth cracking.
BackTrack ISO and VMWare images are available here
.

Many G1/ADP1 owners have been using the app
Tetherbot
to get internet access on their
laptop
via
USB
to the phone’s data connection. The app relied on the
Android Debug Bridge
to forward ports. It worked, but people wanted a solution better than a SOCKS proxy. The community figured out a way to create a
properly NAT’d connection using iptables
and then [moussam] rolled them up into easy to use applications. There’s one for setting up a
PAN device on Bluetooth
and another for
adhoc WiFi networking
. It requires you to have root on your phone, but hopefully you’ve achieved that and are already running the
latest community firmware
.

Here’s another
video demo
of [Eric]’s
Besmoke
interactive fluid simulation that we
covered earlier
. It was put together for the
BIL Conference
last weekend. This time around he’s strapped the iPhone to his head (complying with California’s handsfree laws). To make things interesting, he’s also added
OCZ’s Neural Impulse Actuator
to provide brainwave input.

Also the positioning of the electrodes isn’t quite where you want to pick up good EEG signals. You can monitor some frontal lobe activity but not anything very significant. The SMR strip that runs from one ear to another over the top of the head. Electromyogram and electrooculogram are not brain wave sampling techniques. They are only the electrical activity of the muscles surrounding the eyes. This is notoriously difficult to control consciously. The OpenEEG project is something I’d like to see wired into this.

[Adam] sent us this cool game he made. It is
accelerometer controlled pong
(
translated
). The screen is a Nokia 3310 LCD, tied to an ATmega8 for the brains. He’s using an MMA7260 accelerometer for the controls. The whole thing is encased in an iPod nano box. this looks like a pretty fun little game, though we’d like to see someone attempt a two player match with it.

All bow your heads in reverence to
the Ponginator
. This bad boy is a performance robot, mounted to the end of a 3 story tall crane. He makes all kinds of noises, flashes all kinds of lights, and shoots ping pong balls at 170 miles an hour. This thing looks like it would be so much fun to play with. listen to it as he’s talking and you’ll pick out all kinds of Sci Fi sound effects, from Portal sounds to Star Trek sounds. Check out the second video on the site to actually see the Ponginator shooting.

Sony recently started to shipping the
VAIO P
don’t-call-it-a-netbook
netbook. It comes stock with 2GB of RAM, which means
it’s not eligible
for Microsoft’s XP ultra low cost pc licensing. Hackers wanting to exorcise Vista have run into a few issues. After doing her
unboxing photoshoot
, [tnkgrl] wrote a guide for
replacing Vista with XP on the Vaio P
. She used the
Universal Extractor
to pop open the driver downloads and remove the Vista check. This got the WWAN radio and GPS working in XP. The only casualty was the volume and mute buttons are no longer working. You can see an annotated image
verifying all the components here
.

Notorious hacker conference Defcon has just published their
Call for Papers
. The 17th annual event will happen July 30th through August 2nd. Most of the announcement is the same boilerplate they’ve included for the past two years. Like last year, they’re not defining the specific speaking track themes and will come up with them based on submissions. New for this year is a half-day of workshops on the Thursday before Defcon for anyone that’s showing up early. This pre-con event is targeted at newbies. It certainly sounds like an interesting way to ease into Defcon instead of the usual delays and fire marshals. We’ve been attending
every year since 2005
and love seeing new things. You should definitely consider presenting this year (we want to see more hardware!).

Robotic Baby Crib

This surprisingly pleasant looking crib is actually
a robot, designed to keep babies quiet
and happy all night long. Once inside and locked up, the baby is under the robot’s care. When the robot senses crying, it rocks gently back and forth. This should allow parents the time to catch some sleep. As pointed out in the article, the $5000 price tag is a bit steep. Especially considering the fact that you can get a much less technologically advanced
equivalent for relatively cheap
. How many of you hackers have babies? What hacks did you do to get your babies to sleep?

There are also many videos and magazines with details.Once you have your baby in the oven you can proceed with the crib project. You can then spend many years enjoying both the crib and the baby.Warning: the baby will grow up over the years and in the process consume many resources so be prepared. Fortunately your make skills can come in hand with the providing of these resources. You can also teach the baby how to make things, including it’s own babies (birds and bees project) so that your baby will provide for you in your rocking chair project stage of life.Enjoy.",

[Dave] sent us these fantastic instructions on how to
hack a rear projection tv to be a multitouch interface
. They’ve converted a 67″ inch TV by adding a couple of PS3 eye cameras and an infrared laser plane. There’s lots of great information, like how to replace the lenses on the PS3 eye cameras and how to create the custom fittings needed to make it all fit nicely. You can download the code, but it is Mac only. They claim that this is the first conversion of a commercial rear projection TV to multitouch, but
we know better
. You can see a video of it in action after the break.

Both cameras and projectors require DPI considerations. LCDs have at least 100 DPI, higher quality ones >150 DPI.A 50″ 1080p HDTV has a DPI of 44, making small text difficult to render. Doubling resolution doubles DPI.Since Projectors have a resolution that caps off at 1920×1200… (Being generous), I would require at least two projectors to obtain ~90 DPI.Depending on your end application, a DPI of 44 may be quite fine. If the viewing distance is > ~6 feet, it should suffice.The other gripe I have with this particular project is cost. The HDTV is 2k alone, taking away the DIY allure.Still, the idea of repurposing available hardware is great, since the finishing touches are already present. Using multiple cameras is a plus too. These MT projects are fuelling the development of cohesive and highly usable MT frameworks.Good Job IDEO!",

[xander] built this
LED valentine
for his loved one. It’s interesting because he used
Pyralux
, a flexible circuit board material from DuPont. He describes the consistency as “tough plastic tissue-paper”, but had no trouble using standard toner transfer etching. It has an ATtiny45 microcontroller that pulses the 16 LEDs at an approximation of his heart beat. To avoid soldering a bunch of surface mount resistors, he used two constant current shift registers.

Voice Controlled Home Automation

"voice control"
] |
[Brian] sent in this writeup on his
voice controlled home automation system
. Starting with the Microsoft SAPI, a voice recognition system, he programmed some basic home automation. In a move that makes this project decidedly more awesome, he decided to build a physical representation of his automation system. This disembodied head is “Stephanie”. She responds to her name, has an articulated jaw that moves with the syllables in the words, and even ejects her “brain tray” on command. We want one.
There is lots of information on his site about the circuitry involved, as well as source code and a video. You can see the video after the break.

We’re big fans of surface mount parts. SMD components are cheaper, take less board space, and don’t require drilling; all the coolest new parts are only available in SMD packages.
Smart Tweezers
are an advanced multimeter tool specifically designed to test and troubleshoot SMD circuits. It automatically identifies resistors, capacitors, and inductors, and displays the relevant measurements.
Advanced Devices
sent us a pair of Smart Tweezers to review. We used them while building our
last few SMD projects
, read about our experience with this tool after the break.
Tool overview
Smart Tweezers are a multimeter that measures resistance, capacitance, inductance, and voltage with tweezer-like probes. The probes are shaped to hold loose SMD components, or test components already soldered to a PCB. Measurements are displayed on a small graphic LCD that reverses for left or right hand use. If you’ve ever tried to measure SMD components with a typical multimeter, the value of the tweezer profile is immediately apparent.
Starting at
$300
, this tool is intended for professionals who regularly debug, test, or repair SMD electronics. It’s a bit out of reach for a hobbyist who just wants to salvage SMD parts.
Using it
We tested the Smart Tweezers while developing three recent SMD projects: the
DIY digital picture frame
,
the Bus Pirate version 1
, and an upcoming ethernet device. It’s a real headache to debug an SMD circuit with typical multimeter probes: balance the probes on the correct pins, ensure that the probes don’t create momentary contacts that aren’t due to soldering, and then hold this position long enough to get a good measurement. This only gets worse if you have to repeat several times. The Smart Tweezers test SMD components with a quick single-handed squeeze.
The Smart Tweezers’ graphic menu is navigated with a simple jog wheel. The tool turns on with a press of the jog wheel, and turns off automatically after an adjustable timeout. The default auto-measurement mode attempts to detect the type of component and chooses the best properties to display, but auto-mode is a bit slower than setting a specific measurement mode.
Resistance
Every multimeter measures resistance, a typical multimeter has several test ranges that are toggled manually. The Smart Tweezers measure resistor values between 0.1Ohm and 5MOhms, without manual range adjustments. In the photo we’re measuring a 390ohm, 1% resistor.
Capacitance
Capacitance measurement is a feature that’s found on some high-end multimeters. The Smart Tweezers measure capacitance between 10pF and 499µF. In the photo we’re measuring a 27pF, 5% capacitor commonly used in a crystal oscillator.
A measurement taken from a single capacitor shows its value. A measurement taken from a circuit board shows the total capacitance of all connected components and of the PCB itself.
Inductance
Inductance measurement is rarely found on a multimeter. The Smart Tweezers measure inductance between 1µH and 1H. We didn’t have an SMD inductor to measure, but we tried a through-hole inductor coil from a switch mode power supply.
Voltage
The Smart Tweezers also measure up to 8volts AC or DC. After navigating to the voltage mode, the Smart Tweezers beep until you flip a small, recessed switch in the side of the case. The switch is too recessed to flip with a fingernail, so we used a through-hole resistor lead.
In the photo we’re doing a quick check to make sure that a tiny SOT-23
LTC2631a digital to analog converter
is properly soldered to an adapter board and receiving power.
Continuity/Open Test
The Smart Tweezers have a continuity checking mode that beeps to verify connections between parts. This is an easy way to make sure every leg of a large SMD chip is properly soldered, or to hunt for broken/damaged components.
Current
The Smart Tweezers don’t directly measure current consumption, but it’s easy to calculate using voltage and resistance measurements with the equation Ir=Vr/R.
A look inside
As with any tool, we can’t help but take it apart and see what’s inside.
The batteries are replaced by removing three screws and the front cover of the device. This view reveals the batteries, the LCD screen, a small piezoelectric speaker, and the back of the circuit board.
A single screw in the back of the case holds the circuit board in place. We removed the screw to expose the front of the circuit board. The Smart Tweezers are powered by a
Texas Instruments MSP430F135
microcontroller and a half-dozen analog chips. The MSP430 line is well-known for low power consumption, and it’s a logical choice for a portable device. Most of the passive support components are size 0402 or smaller.
Conclusion
The Smart Tweezers saved us a lot of time constructing and debugging three surface mount electronic designs. A simple squeeze and test is much faster and easier than awkwardly probing tiny parts with our cheap multimeter. It’s so much easier, in fact, we could hold the Smart Tweezers with one hand and take all the photos in this article with the other; try that with a normal multimeter.
We think two small changes could make the tool even easier to use. First, a larger button would make it easier to switch to voltmeter mode without a wire or screwdriver. Second, it would be really nice if it could be turned-on by squeezing the tweezers together, rather than pressing the jog wheel.
We really liked the automatic component detection and auto ranging, and the measurement speed is excellent. We appreciate that the tweezer tips are replaceable because we’re really hard on our tools.
If you’re a professional or student who does a lot of work with SMD electronics, a pair of Smart Tweezers can save you time by reducing awkward multimeter measurements to a simple squeeze. This fairly expensive tool is probably overkill for all but the most hard-core hobbyists, but if you derive income from electronics, like we do, Smart Tweezers can be really handy.

The only reason that this one is being endorsed is that “Advanced Devices sent us a pair of Smart Tweezers to review”.C: Nearly every techie who has ever had the misfortune of using a computer without ad blocker has come across a banner ad for this device. And my guess is that the vast majority of us have decided against it as soon as we saw the price. Because of the rampant advertising that Advanced Devices does, this post is quite superfluous.",

[Pedram] Sent us his
USB missile launcher interface project
. He happened to have some of the USB missile launchers lying around. having lost their initial draw, he wanted to do something to spice it up. He wrote an interface in python so he could control the launcher via his iPhone. We don’t see how this is any different than controlling them by the computer, but he seems to have put a decent amount of work into it.

[tnkgrl] has concluded her
Sony Vaio P
by
adding GSM support
. We covered the
switch to XP
earlier, but this should work on Vista too. The Vaio P is sold in the US with support for Verizon’s EVDO wireless broadband, but it uses the same hardware as the European model that uses GSM. This is possible because of the the Qualcomm Gobi radio module. To get GSM support, you trick the VZAccess Manager into loading a different firmware than the stock EVDO. The difficult part is that the Vaio P doesn’t come with a SIM card slot, so you’ll have to solder in your own. When you’ve got the computer reassembled, just change VZAccess Manager to use your carrier.
UPDATE:
Wired has an
article on the Gobi chipset
.

[psymansays] needed a
panning head
for his robotics projects. Already being familiar with the
NXP LPC2148
from work, so he wanted to use that to control it. he built his own carousel out of old CDs. The axle of the carousel is a potentiometer. This is what he’s using to determine position. The gear motor was actually cobbled together with bits from a windup toy and an old motor. This may be a bit bulky, but it seems not only functional, but fairly versatile.

Linear Technology’s
LTC2631A-LZ8
is an 8bit
digital to analog converter
(DAC) with an
I2C
interface. This DAC can output 255 different voltages, spaced evenly between 0 and 2.5volts. We previously demonstrated the
LTC2640
with a three-wire
SPI
interface, but this version is controlled with only two signal wires.

We used the
Bus Pirate universal serial interface tool
to work with the DAC, but the same basic principals apply to any custom implementation. The connections between the Bus pirate and the LTC2631A are outlined in the table. We powered the chip from the Bus Pirate’s 5volt supply, but it would also work fine at 3.3volts.
The I2C bus requires
pull-up resistors
on both bus wires. 5volts is supplied to the pull-up resistors by connecting a wire from the 5volt supply to the pull-up resistor input terminal. Close the jumpers on the clock and data lines to supply the external voltage to the pull-up resistors.
Now, setup the Bus Pirate for I2C mode and activate the on-board power supply.

After configuring the Bus Pirate, the voltage monitor shows that the 5volt supply is active (4.9volts). Additionally, the monitor shows that 5volts is connected to the pull-up resistor supply terminal (VPULLUP).

<–got reply from these addresses
I2C>
The state of pin 1 and 8 determine the LTC2631A I2C address, according to the table on page 22 of the datasheet. Instead of looking up the address in the datasheet, we used the Bus Pirate’s I2C address search macro to scan the entire I2C address range. The DAC responds to the set address (0X40) and a global address (0xE6). The global address is useful for controlling multiple DACs simultaneously over the same I2C bus.
I2C>d [0x40 0b00110000 0xff 0] d
9xx VOLTAGE PROBE: 0.0VOLTS
<–output

210 I2C START CONDITION
<–start transaction
220 I2C WRITE: 0x40 GOT ACK: YES
<–DAC address
220 I2C WRITE: 0x30 GOT ACK: YES
<–set DAC output command
220 I2C WRITE: 0xFF GOT ACK: YES
<–set DAC to full (255)
220 I2C WRITE: 0x00 GOT ACK: YES
<–don’t care, extra byte
240 I2C STOP CONDITION
<–end transaction
9xx VOLTAGE PROBE: 2.5VOLTS
<–output at full
I2C>
Now we’re ready to interface the DAC. An initial voltage measurement (d) shows that the DAC is currently outputting 0volts.
An I2C start condition ([) alerts connected I2C devices to listen for their address. The first byte is the address (0x40) that identifies the device we want to access. The next byte is the LTC2631A command to update the DAC output (0x30 or 0b00110000), followed by the output setting (0xff or 255, 100% output). The final byte doesn’t matter for the 8bit DAC we’re using, but carries additional data bits for higher resolution versions of the DAC. The transaction is completed by sending the I2C stop condition (]).
After updating the DAC to 100%, a voltage measurement (d) shows that the output is 2.5volts.
I2C>d [0x40 0x30 0 0] d
9xx VOLTAGE PROBE: 2.5VOLTS
<–DAC at 100%
210 I2C START CONDITION
220 I2C WRITE: 0x40 GOT ACK: YES
220 I2C WRITE: 0x30 GOT ACK: YES
220 I2C WRITE: 0x00 GOT ACK: YES
<–set DAC to 0
220 I2C WRITE: 0x00 GOT ACK: YES
240 I2C STOP CONDITION
9xx VOLTAGE PROBE: 0.0VOLTS
<–DAC at 0%
I2C>
A similar command sequence sets the DAC output back to 0. A voltage measurement confirms that the DAC output is now 0volts.
For a complete list of DAC features and command codes, see the in-depth discussion of the LTC2640 SPI DAC at the end of the
Bus Pirate version 1 how-to
.
Are there any chips you’d like us to interface in future

You provide 4096 clock ticks, and then trip the reset pin. Inside, the 5940 has counters that turn off the LED when the clock ticks equal the duty cycle you program through the SPI interface; all come back on when the reset pin is triggered.As I recall, I connected the oscillator output of a PIC16F628a to the TLC5940 clock input, and used the PIC’s counter to count to 4096 and then toggle the reset pin on an interrupt.Now, can this be done with the Bus Pirate? Sure, but it will need a new module that creates the clock signal on one AUX pin and the reset on the other. This isn’t difficult, but it’s not a feature the Bus Pirate currently has.",

Radio Controlled Beetle

Scientists at the university of California have managed to
implant a chip in a giant flower beetle
that makes it respond to commands from the computer. They can tell it to fly, stop, turn left and turn right. The controls are done through its optic nerves and wing muscles. Though the article states that flight signals are sent to the optic lobes and steering is done through stimulation of the wing muscles,
the video shows steering being accomplished through optic lobe stimulation
.
Though we’re sure there’s some grand scientific goal behind this, we can’t help but think (hope) that we’ll be seeing giant robot controlled beetle battles with lasers and rockets.

That seems a much crueler fate for the beetle, but I don’t see anyone launching an extermination campaign against Ampulex Compressa. Of course, maybe that is that is because Ampulex Compressa is not a convenient political target.",

I was thinking to myself “hm.. with a controller that small, they could easily build a “beetle” from scratch that would do the same exact things as this one, with out having to be concerned with it running off, or needing to add leg-movement inhibitors.In other History of Tech news:There was a project to burn out Japan by using Bats deployed with time release incendiary devices on their beings. They would fly in to roost after being deployed from an offshore bomber plane in the very early morning. As they left the bomber deployment system, they would prime the incendiaries. After finding roost, the incendiaries would ignite and burn Japan to the ground. It was developed and fully tested in the US before the war with Japan ended with WW2. The thing that stopped it from going ahead was the nuclear weapons program that was a month from being ready for deployment over Japan. The bat project was canceled and the nukes were dropped soon after.Anyway.. technology is a trip!",

For those of you who don’t recall, the
Wiremap is a 3d volumetric display
built from hundreds of tiny strands. An image is projected onto the strands to achieve 3d effects. [phedhex] has posted an in depth instructable on
how to build a wiremap
. He covers the construction with lots of good tips as well as giving links to the software for Windows, Mac, and Linux. Check out the video after te break to see some fairly impressive 3d patterns.

With the impending digital switchover, many of you will find yourselves not only in need of a new converter box, but an antenna as well. Just like everything else, there are
plans out there
on how to build your own. [William] has gone through the effort of
documenting his design and build
of a very nicely made version. He used PVC for the frame and a wire mesh or chicken wire reflector. Good job [William]

If you’ve ever wanted to play with tangible tracking systems quick and cheap, you might be interested in this
super quick tracking surface
for trackmate.
Trackmate
is open source software for physical object tracking. Making a surface for it isn’t that hard in the first place but this one is probably the easiest. All you really need is some Plexiglas, some c-clamps and a web cam. The whole thing packs into a backpack or over the shoulder bag. This would be perfect for live performances.

Desulfator In An Altoids Tin

If you’ve ever let a car sit for a period of time and returned to find that the battery was mysteriously “dead”, you were probably experiencing a sulfate crystal build up. Often, people just buy a new battery and plop it in, but that isn’t absolutely necessary. [Kmpres] takes us through the process of
building a desulfator
. A desulfator works by putting high voltage pulses into the battery forcing the sulfate crystals to dissolve back into the electrolyte. From what [Kmpres] says, you can find “bad” batteries in all kinds of places, use the desulfator on them and have perfectly fine batteries when you’re done. You may recall doing
something similar with a disposable camera
.

If you read the instructable and check out the links in it, you’ll see that they are used to restore not just car batteries, but also large banks of batteries in PV banks, electric golf carts, wheelchairs and many other applications. It’s not a patch and it doesn’t result in a temporarily improved but degraded battery. It instead, reverses the process of sulfation returning the lead sulphate to the electrolyte, from whence it came. With the lead sulfate off the plates the acid can contact the lead again and the battery can produce electricity up to its normal capacity. Desulfators are especially useful for owners of RVs and off-grid PV systems (if sufficiently scaled up in size) because they can get 10 years or more of life out of their very expensive battery banks instead of having to replace them every few years due to sulfation buildup. Again, the process simply returns the lead sulfate to the electolyte, from whence it came, so there’s no buildup inside the battery after the process is complete. And it keeps your battery out of the local landfill where it pollutes the ground and water. For me, that’s worth the small price of this circuit alone.",

This is a pretty useful device. It is an
IR controlled light dimmer
. It goes in line with the main power and controls how much gets through to your light. You can adjust the brightness with a TV remote control. Finally, we can retire our
clapper
! These are commercially available, but making your own is just so much more fun. You may have to dig a little on their site for the schematics and programming. There are tons of other projects there as well so have fun. You can see a video of it in action after the break.

The first talk of
ShmooCon
was [Ethan O’Toole] and [Matt Davis] presenting their
OpenVulture
software for unmanned vehicles. In the initial stages, they had just planned on building software for Unmanned Aerial Vehicles, but realized that with the proper planning it could be used with any vehicle: airplanes, cars, boats, and subs (or more specifically, their Barbie PowerWheels). The software is in two parts. First is a library that lets you communicate with each of the vehicle’s modules. The second half is the actual navigation software.
They’ve spent a lot of time sourcing hardware modules. They are looking for items that work well, aren’t too expensive, and have a fairly plug and play implementation. For their main processor, they wanted something that wasn’t a microcontroller and could run a full Linux system. The ARM based
NSLU2
NAS seems to be the current frontrunner. You can find the opensource software and descriptions of the supported modules on their site.
They’re building the first test UAVs now. One has a 12 foot wingspan for greater lift and stability. We’ve covered the Arduino based
Ardupilot
and
other UAVs
in the past.

For those who enjoy photography, a ring light is a nice tool to have. Being hackers, making your own seems only logical. This writeup will take you through the process of
making one from fiber optics for super cheap
. They basically gutted some fiber optic toys and strapped them to the lens. Sure there was a little more work involved, but that’s the gist of it. You may recall some more
in depth fiber optic ring lights using LEDs or cold cathodes
that we covered before.

[MikeFez] sent in this info about his
augmented FPS set ups
. He started this project back with an original XBox in 2006. He wanted a more immersive way of interacting with his games. Pointing out that gaming visuals and interactivity have come leaps and bounds while the controllers themselves have basically just added a few buttons, he explains his goals. He wanted to have to move his body to move his character and possibly physically aim. The
original project
, for the XBox, was successful in that he used a floor pad to control his character. Since then, the Wii has come out and he has moved to the PC as his main platform. As expected, he is now using the Wiimote as the aiming device.

Move your head up and left to look up and left, for example. It works pretty well, although it definitely needs a bit more smoothing in order to be usable. I’m gonna post it somewhere once it is “finished” and hopefully people can make some improvements.I like the idea of using face tracking simply because nobody likes wearing stuff on their head so that they can play, although I reckon that’ll change as 3D TV becomes more mainstream.",

It provides detection and recognition, but I’m only using the detection classes. It also handles webcams rather nicely, which is good. I’m writing the code in C#.Anyway, face detection works fantastically; on my Core2Duo system at work the limiting factor is the webcam’s framerate. It isn’t so great on my 1.66Ghz Atom netbook when running side by side with Quake 3, but without Quake running it is fine.I’m basically just using user32.dll to send mouse movement events when the face moves, so you can use it to mouse around the windows GUI. This actually works better than within a game right now; when the mouse cursor is moving you don’t notice the jerkiness too much, whereas in Quake you notice it a lot – jumping from view to view sort of disrupts the optical illusion of motion and makes it look like the game is running at a low framerate.The problem with jerkiness isn’t inherent to the concept, it is just resulting from me recycling old classes that i was originally using to control a couple of servos rather than a mouse. once i get around to sorting it out it should be great.",

Sure, there are incredible advancements in graphics, but your still interacting the same as you did 20 years ago, albeit with a couple more controls.You can choose to keep on going using a controller, or play them in a new interactive and immersive way. But its true, controllers will most likely always be the standardized way of playing, and as you can see in the original xbox design, the controller is still the form of interaction, the choice to use a DDR pad is as simple as hooking it up when you want and disconnecting it at the more difficult boss.

The registration desk hasn’t opened yet at
ShmooCon 2009
, but we’re already running into old friends. We found [Larry Pesce] and [Paul Asadoorian] from the
PaulDotCom Security Weekly
podcast showing off their latest ShmooBall gun. ShmooBalls have been a staple of ShmooCon from the very beginning. They’re soft foam balls distributed to each of the attendees who can then use them to pelt the speakers when they disagree. It’s a semi-anonymous way of expressing your dismay physically. [Larry] has been building bigger and better ways to shoot the ShmooBalls for the last couple years. You may remember seeing
the 2008 model
. This year the goal was to make the gun part much lighter. The CO2 supply is mounted remotely with a solenoid valve and coiled air line. The pistol grip has a light up arming switch and trigger. The gun is fairly easy to transport: the air line has a quick disconnect and the power is connected using ethernet jacks.

You can’t that a connector meant for digital signals and expect it to work for millivolt analog signals! a digital circuit doesn’t care if it gets 5 volt logic or 3.9 volt logic usually, so even a couple ohms of resistance would be tolerable, but in millivolt signals this *ABSOLUTLEY* isn’t true!

TinkerKit
is a collection of 20 different sensors and 10 actuators. It’s meant to make prototyping of physical computing devices much quicker/easier. The devices plug into a Sensor Hub
Arduino
shield. There is also a similar hub board that can emulate a keyboard; it translates sensor input directly to key strokes. It looks like a very ambitious project and it’s
still in development
. We love the idea though and think the wide variety of components will foster better final designs. The TinkerKit site covers the current component lineup and there’s a demo video embedded below.

It seems some enterprising individual in Grand Forks, North Dakota has been
placing fake parking violations on cars
. If the recipient visited the URL on the flyer, they would be told to install a toolbar to view pictures of their vehicle. That piece of malicious software would then attempt to install several more. The actual vehicle pictures were from Grand Forks, but we wouldn’t be surprised to see a similar attack happen in a much larger city.

SparkFun has been selling button pad parts for some time and we used them in our
RGB door lock project
. A excellent part, but you needed to implement your own interface to use the boards. SparkFun has just released two additional versions to make it easier on builders. The first is their
Button Pad Controller USB
. It has a 4×4 grid of buttons lit by RGB LEDs and a USB interface. This board can be expanded using the
Button Pad Controller SPI
. The SPI bus means it should be easy to add the button pad to embedded projects. This newest release puts you much closer to building your own
RGB monome clone
or other custom controller than ever before. The unit pictured above is their own project and they have no plans on selling anything like it.

After running a successful hacker convention for ten solid years, the people who brought you
ToorCon
are planning a new event to shake up the US hacker scene.
ToorCamp
will be held July 2nd-5th, 2009 at a former missile silo in central Washington state. Hackers will camp on-site for two days of talks followed by two days of workshops. Art and music events are planned for every night. Camps like this are already help biannually in Europe:
What the Hack in 2005
,
Chaos Communication Camp 2007
, and
Hacking at Random 2009
, coming this fall. The complex is one of three
Titan 1
missile complexes in the Moses Lake area. The sites were in operation
less than three years
between 1962 and 1965. The former missile command center has been converted to a
secure data center run by Titan I, LLC
. ToorCamp promises to be a very unique experience and we’re looking forward to attend this and future years.

[Raphael] sent us this nice
kick pedal mod for Guitar Hero: World Tour
. After breaking his kick pedal repeatedly, he decided to build something a bit more robust. He went to the music store intending to pick up a cheap kick pedal to start with and happened to start a conversation with an employee who had a practice pad to get rid of. [Raphael] relieved him of his practice pad and promptly made a base to hold it in position. After attaching his piezo sensor to the back of it, he had a very robust kick pedal. we can’t imagine him breaking this one any time soon.

The 360 version is a little more difficult, as it requires the Microsoft wireless reciever thingy, and a short hack. I don’t know about the Wii version (that’s shown) but I would guess it’s just like other wiimote add-ons, which require a bluetooth dongle and a program called glovepie (under windows anyway). Once you have it working like that it’s really not that hard to make a program which interprets the hits and plays either a sampled drum sound or the correct midi note (By midi I meen the “music” format not the instrument connection standard).",

You could have the pedal hit against a small block of wood with the sensor and it would probably work just as well.And joe57005, your comment is about as creative as pretending to play music… seriously the whole “learn to play a real instrument” insult is played out. There’s a lot of people out there who would rather drop a small amount of money on a game like this and have a few hours of fun with their friends who aren’t at all interested in spending a large amount of money and several years learning to play a real instrument.",

I actually did exactly what you’re describing for my neighbor’s Rock Band 1 pedal, and I’m going to put up a tutorial shortly with full details.Basically, it’s a cheap magnetic switch like what you’d find in an alarm circuit. Bob (my partner-in-crime) and I simply took a piece of wood, strapped it to the front of the pedal, attached the wired portion of the sensor, and covered it in carpeting to dampen the sound. I turned the beater around to thump against the sensor, and embedded a magnet into the beater itself. Very easy and portable (but only compatible with Rock Band).The practice pad simply gives you a nice muffled surface to attach a sensor to. It does a great job, but it’s not technically required.To those of you who want me to end world hunger or hack the pentagon, who do you think I am? Bob Geldof? Kevin Mitnick?Oh, and I never claimed I came up with this stuff; people have been making this stuff for GH:WT and Rock Band for awhile, and real musicians have been using stuff like this for years. The reason I put this up is that fixing up broken GH / RB controllers is much easier than most people think!",

Surely it must or it wouldn’t work (or am I missing something, like it being specifically programmed into GH:WT how to handle it rather than using the standards set by nintendo. I just hate it when developers do that.) I suppose the guitar would have to work like that as the GH3 one did and it would need to be the same for backward compatability (of both the game with the GH3 one and GH3 with the new guitar) but is usppose drums wouldn’t have the same restrictions (Harmonix didn’t even use wiimote add-ons for their periferals, so i suppose it could be worse)",

The post on the latest update of Glovepie, 0.3.0, says it’s got some wiimote calibration / IR bugs but that a patch should be out ‘shortly’. It never actually came out, at least to my knowledge.However… as far as the ‘not registering’ stuff goes, what I meant to say was that GlovePIE doesn’t see it as a connected extension, and can’t initialize the device because it doesn’t know what it is or whether it’s plugged in properly. Using the ‘detect input’ tool in GlovePIE doesn’t do anything because the drum kit is still waiting for something. However… good news, you can always count on the Frets On Fire community to hack the everliving crap out of something.Check this thread out:http://www.fretsonfire.net/forums/viewtopic.php?f=3&t=29037&st=0&sk=t&sd=aApparently, it works, but I haven’t had the chance to try it yet. I’ll blog it up if I do, of course.I don’t think this is exactly a case of the developers specifically making it hard for us; it’s just that without a little bit of knowledge about how it works (where it writes in the Wiimote memory, for example) it’s a question of dumping all the bluetooth traffic and figuring things out by hand.The Wii itself makes things a bit harder than the other platforms, I think. As far as standards go, I just bought RB2, and the GH:WT drums work flawlessly, so there’s definitely no secret magic going on.Anyway, if you try this and it works, let me know!",

Punchy Punchout Controller

We love alternative inputs. They can revitalize an old classic or add a twist to most any mundane task. Here, we see a perfect example where the game
Punch Out for the NES is being controlled by a punching bag type thing
. The impact sensors were made by hand, and wired to a PC game pad. They were mounted on some foam, allowing for a nice mushy punching surface. There’s some feedback too, when your character is hit, a custom script detects the change in the sprites color and sends a signal to an Arduino. Right now, it just lights an LED, but the goal is to signal a strobe to make you flinch. This looks like it would be fun to play with, especially if you were to make it a little more high impact. You can see a video of them lightly assaulting it after the break.

[Chris Paget] is going to be presenting at
ShmooCon 2009
in Washington D.C. this week. He gave a
preview of his RFID talk to The Register
. The video above demos reading and logging unique IDs of random tags and
Passport Cards
while cruising around San Francisco. He’s using a Symbol XR400 RFID reader and a Motorola AN400 patch antenna mounted inside of his car. This is industrial gear usually used to track the movement of packages or livestock. It’s a generation newer than what
Flexilis
used to
set their distance reading records
in 2005.
The unique ID number on Passport Cards doesn’t divulge the owners private details, but it’s still unique to them. It can be used to track the owner and when combined with other details, like their RFID credit card, a profile of that person can be built. This is why the ACLU opposes Passport Cards in their current form. The US does provide a shielding sleeve for the card… of course it’s mailed to you with the card placed outside of the sleeve.
Technology exists to generate a random ID every time an RFID card is being read. The
RFIDIOt
tools were recently updated for RANDOM_UID support.

Monocular Head Mounted Display

[Xenonjon] wanted to make a Heads Up Display that he could use while maintaining the ability to see. The most logical choice was a monocular set up. He had an old Eye-Trek laying around and decided to
sacrifice it to make his Heads Up Display
. Combining a screen from his TV glasses and a wireless security camera setup, he was able to achieve an untethered monocular HUD. This has a multitude of uses, from displaying vital information, to home made night vision, or just watching TV while you work.
There’s plenty of good pictures and information there. The final result is a pair of safety glasses with the display and a pack that you have to put on your belt that holds batteries and the wireless receiver. It seems as though it isn’t horribly cumbersome, but we’d have to try it for a while to say if it would be ergonomically sound.

Plus have owned the Virtual IO, Olympus FMD-200 & Rimax Virtual Vision 4.0XL.The Olympus & Sony glasses have superb prism optics whilst the others (apart from the I-Visor) have terrible straight-lens optics, the Rimax glasses should be avoided at all costs because you can’t align your eyes up properly with the screens no matter how hard you try.Using LCD glasses for a long time isn’t all about eyestrain but how comfortable they are to wear, the Rimax 2.0 & 4.0 have straps and so squeeze your head giving you a headache (if you can bear to look at the screens for long enough) whilst the Olympus & Sony are much nicer to wear as they’re traditional glasses-with-arms type -apart from the PLM-700’s which strap onto your head but are actually comfortable to use for an hour or two.After an hour or two even with good LCD glasses you can get eyestrain, but using one screen+optics from an Olympus FMD-200 in that style I don’t think you’d get a lot of eyestrain because you can still see the real world around you which your eyes are naturally used to.The Sony PLM-700’s have see-through capability where you can see right through the LCD screens (or have them blanked off by means of a secondary LCD screen that blacks out) but this feature gets annoying because it’s like wearing sunglasses and in sunlight the LCD screens aren’t that bright anyway.",

Pong Playing Robot

[vimeo=1564591]
Sometimes, it can be very difficult to find a partner to play pong. Lets face it, pong just isn’t worth playing alone. Someone has come up with the perfect solution, a
robot built specifically for playing pong
. It watches the “ball” with a web cam and presses the appropriate buttons on the keyboard with its tentacle like arms. It is vaguely reminiscent of the switchboard operators from Men In Black, and definitely overkill for the job. You may notice there seems to be some performance issues with their game of pong. I doubt that the game itself is that taxing, but the same computer is controlling the robot as well.

[prabbit22m] has written an instructable on
how to build a radio controlled sphere
. The mechanism is fairly simple, with one drive motor, one servo and a gyro for stability. To turn, the servo shifts the center of gravity off to one side. You can see that the system works pretty well in the video above. If it didn’t have that gyro, it would be insane, believe us,
we’ve done our own experimenting
. If you like this, but want more features, check out this one that
has a camera and takes pictures wherever it goes
. We can’t forget Swarm either. The
autonomous swarm of robot spheres
. Of coarse [prabbit22m] might have the best idea of all. Dress it up as a regular ball to mess with people.

Haptic Compass
|
Caleb Kraft

[
"classic hacks",
"Wearable Hacks"

[
"clown belt",
"compass",
"haptic",
"vibrator"
] |
[eric], inspired by
this Wired article
, built his own
haptic compass
. Named “the clown belt”, it is a belt with 12 little vibrating motors mounted evenly all around. A digital compass vibrates whichever motor is closest to north at all times. This basically gives the owner an extra sense. He doesn’t go much into his own experiences, but the Wired article mentions “dreaming in north” and feeling strange once they finally removed it. Precise direction senses may not be super power worthy, but they would be cool.

With 12 you don’t get that, you don’t even really get northeast.Obviously the more points the more accurate, with a continuous loop being ideal.I would probably use something other than a vibrating motor too, maybe setup a switch that just is on or off and pokes you.

He describes that he would get a feeling of fear when he was about to bump into stuff. He now is building robots with nerve cells from rats which he tries to condition.Interesting stuff, as is the hack discussed here. I’m also curious whether one could learn to develop an persistent extra sense this way (also when you would unhook the device). Maybe we pickup more signals than we think and some training to can learn us to link the stimulus to the source.",

Cellphone viration motors have gotten small enough now you could probably incorporate a compass band into the strap for an over-the-chest heart rate monitor.With some other sensors you might be able to turn into a “survival band” that’s one part GPS/compass and one part bio monitor for deep wilderness trekking.

We don’t want your brains to explode, so just trust us that
this is a truly one sided circuit
. Being a
mobius strip
means that this circuit has uber geek bragging rights. Beware, your friends who have never heard of a mobius strip will argue until they are blue in the face that there are two sides to it. The circuit they chose was fairly appropriate, an LED “chaser”.

The Möbius strip has the mathematical property of being non-orientable. It can be realized as a ruled surface. It was discovered independently by the German mathematicians August Ferdinand Möbius and Johann Benedict Listing in 1858.A model can easily be created by taking a paper strip and giving it a half-twist, and then joining the ends of the strip together to form a loop. In Euclidean space there are in fact two types of Möbius strips depending on the direction of the half-twist: clockwise and counterclockwise. The Möbius strip is therefore chiral, which is to say that it has “handedness” (right-handed or left-handed).It is straightforward to find algebraic equations the solutions of which have the topology of a Möbius strip, but in general these equations do not describe the same geometric shape that one gets from the twisted paper model described above. In particular, the twisted paper model is a developable surface (it has zero Gaussian curvature). A system of differential-algebraic equations that describes models of this type was published in 2007 together with its numerical solution.The Euler characteristic of the Möbius strip is zero.In other words THERE IS ONE EDGE AND ONE SIDE. if you were to walk the Side, you’d end up back at the beginning going around the strip twice and this goes the same for the Edge because both left and right edges are the same edge once you’ve turned the trip into a mobius strip.People who disagree clearly don,t know what a mobius strip is. Your welcome for explaining what it is in detail, thank Wikipedia for the genuine information.",

[Aki] had a broken TAC-2 joystick that was just begging for some new and improved use. Since it was the cable that was broken, [Aki] had the idea to
make it wireless
. He designed custom boards for the transmitter and receiver. Each is controlled by an ATTiny2313. He fitted it with the stock connector so it could possibly even still work on a commodore 64. He hasn’t tested that yet though.

[Joe] sent us this project called
Laser Pup
. After seeing many other projects with the ioBridge like
beer pouring
and
dog treat dispensing
, he wanted to make his own. His project allows him to play with his dog via a ceiling mounted laser pointer. We know, you were hoping for something more along the lines of
Laser Cats
, but this is still pretty cool. He built a web interface specifically for the iPhone to control the laser, room lights, and show a live feed of the puppy playing. You can see a video of it in action after the break.

Since our
last post
about his
WiFi Streaming Radio Project
, [Jeff] has been hard at work to release
part 8
of the project where he adds tuning control to the radio. Interestingly enough, the addition of the tuning control only requires a potentiometer and the completed AVR LCD board from
part 7
. After wiring the potentiometer to the analog to digital converter on the AVR and adding a few lines of code, the radio can now be tuned quickly and easily. In addition to thoroughly explaining the hardware changes, [Jeff] details the configuration changes required to the OpenWRT framework so that bidirectional communication between the router and AVR is possible, allowing the tuner to function properly. Be sure to check out the video above to see the tuner in action.

AppleDifferent decided to run some benchmarks on their MSI Wind hackintosh to see
how it stacked up to real Apple hardware
. It comes in under the
MacBook
Air in most cases and they conclude that it performs about as well as a four year old G4. Being so small and inexpensive, you can’t really expect much better. As a counterpoint, Obsessable posted a video demoing just
how slow a first generation Eee PC can be
(embedded below). Boing Boing Gadgets is maintaining an
OSX netbook compatibility chart
. It shows that the MSI Wind is probably the best case for OSX usability. If we were buying today, we’d probably pick up a
Dell Mini 9
even though it requires an SSD upgrade before it will sleep properly.
Are any of you running OSX as the primary OS on your
netbooks
? What has your experience been?

Certain things don’t work great, or at all, but it’s a spectacular little machine. I use it primarily for note-taking during lectures (my campus is large, so as portable as my MBP 15″ is… it can be a burden on the shoulder. The Wind, meanwhile, isn’t.)The camera’s not working at the moment (I believe there’s a hack to fix that… don’t have a need), and the touchpad is a little wonky (looking to buy the nicer Synaptic pad), the wireless isn’t natively supported (ordered a card that was, so I could get rid of the 3rd party utility), and you have to run a script to change from tinny speaker out to headphone jack out and back, but with a second gig of ram in it, it performs spectacularly for what I need — lots of terminal stuff for programming, fairly heavy web browsing (taboholic here), SSH, VLC, and some light XCode usage (really, most of my stuff is VIM + GCC). I’m actually in the process of setting up a more consistent connection for when my laptop is at my Apt., so I can SSH/VLC into it from the campus Wi-Fi as needed.So my verdict? I couldn’t use it as a primary machine, but for mobile use, it’s hands-down better than my $3k MBP that’s a year old. If nothing else, it’s less clunky to get out and the battery life is phenomenal — I bought it for not much more than it would’ve cost me to replace my mbp’s battery (1 year, 320 charges, gets 40 minutes to a charge now) and a second charger (which was what I was looking at before I decided to go with the Wind). A little rsync magic to keep files together, and I couldn’t be happier with the result.Would buy again! :P",

Definiatly not a primary machine but for taking notes or looking up something quickly in meetings it cannot be beat. I also intend to use it for lectures where I teach. With the 2MB of RAM its surprisingly snappy. Not killer, but more than “just usable”.Cons: Battery life is not fantastic. Booted as windows I dont need to bring my power block. I think it manages sleep power better. Even putting it to sleep in OS X it draws down the battery. Other quirks like wireless driver and headphone out are not really a hinderance to me.Overall I still tell my coworkers and fam just to buy a macbook. I explain it to them that the beuty of Apple products is that they nail it on 97% of the use cases. Just lovely to use. There are still some quirks but for the most part, its awesome. OS X on the Wind is like nailing it on 85% of the use cases. As long as you keep that in mind, its perfect for me.",

Because of the way it’s set up, you’re also stuck on whatever version of OSX that DVD is.The Mini 9 can be installed using an original OSX installer and a (free) boot CD available online. I’m not an expert, though I am running OSX on mine, but I believe it emulates EFI that OSX needs to run and loads up the nonstandard drivers necessary from a directory on the hard drive. This means that you can comfortably autoupdate the OS without it crashing. Every feature on the netbook works, including the camera and wireless (no special software requires) and even sleep. I didn’t even need a USB DVD drive to do it, I was able to image the media required to USB drives (though I had to borrow a friend’s Mac for the Leopard one.)The only caveats are that sometimes 0 acts like it’s stuck down after you resume from sleep–just hit Esc to fix that–and the card reader just supports SD/SDHC.For reference:http://mydellmini.com/forum/howto-install-os-x-the-right-way-type11-boot132–t1106.html",

It’s hardly worth calling it a hack, running OS X on it, as the folks behind this have made it so easy for the end user to do it. I don’t think there is any other netbook out there that works as well with as much ease for an install. It really does ‘just work’, even when installing it from a USB drive. And the best part is that it doesn’t take a hacked distribution of OSx86, you just use a retail disk and install it after booting off the 132 disk.",

"content": "It’s true that the Wind’s install process isn’t as clean at the moment as the Dell’s, but there’s a couple different methods of going through it discussed over @ msiwind.net’s forums. You’re not, however, limited to the install DVD’s version — the latest release was Leopard .4, but using software update and then re-installing some kext’s (some people need an external keyboard for this, I didn’t) make everything work in the latest version. I used my friend’s resources (borrowed his DVD+drive), so I was actually using an older hack then updating to the latest. The community for the Wind is great though, and there’s guides for various ways of going about the install. They talk about with an external DVD drive and a retail DVD, with a drive and a pre-hacked DVD, with a USB drive… even a method for installing with no USB media at all (I don’t know the details, I’d assume they’re doing a netboot or a partition built to do the install). There’s options, documentation, and a healthy community of supporters for people who have questions/problems. Having only used the Dell in passing, I can’t really give a good verdict on which is better, but I’m pretty happy with my Wind.",

Cheers! I also put the SkinGirl “Starry Night” decal set on my (white) 150, and snuck a sparkly gold Apple logo over the moon in the photo. Bonus points. The install wasn’t so bad after a few tries and days of forum crawling. It mostly worked out of the box, just needed a couple tweaks, and of course swapped out WiFi cards. Everything works great currently whee. The dual-boot management was the only super-pain.",

Once in a blue moon the OSX boot will hang on a blue screen, but a single user/fsck will fix it up a treat! The thing is the most robust, flexible computer I’ve ever owned. I have a closet full of macs and pcs and this is still my fave. I upgraded to 2GB RAM and I can’t be happier. Obviously, you need to understand that you’re not doing any FCP rendering or HD video on it, but the damned thing outputs 1440×900 VGA!!! I’ve also had fewer kernel panics on this than on my 2.33GHz Macbook Pro. It’s simply amazing. I will definitely ebay for another when this kicks the bucket.",
