"class action",

"sony"
] | On April first Sony rolled out new firmware for the PlayStation 3 that removed the ability to install Linux on the system by blocking a feature called OtherOS. Now
a class action lawsuit has been filed against the company
for its actions. It doesn’t take an attorney to figure out that they removed features that were a major selling point for the system. As mentioned in
our previous article
, the ability to use an exploit to access the hardware doesn’t mean that every user installing Linux on the system plans to do so. The suit asserts that users had no opportunity to negotiate the System Software Licensing Agreement which is only presented to a purchase after the sale is made. The lawsuit is availble
in PDF from from IGN
.
Who knows where this one will end up. The suit seeks an injunction against the removal of the OtherOS feature as well as compensatory damages. No matter what happens, we still think the removal was a bad move on Sony’s part.

a separate machine to take care of the 6x6x6 cubes
too. See both in action after the break.

building the original

To summarize, he has lowered the mower and reversed/bent the blade to scrape the ground. He has also added thick rubber edges all around to try to keep debris from coming out. You might be wondering why he would need something like this, but the last page sums it up pretty well. We could imagine this possibly getting some use in the garden as well. This one does look pretty dangerous though, so don’t blame us if you cut off a hand or lose an eye to some debris. Then again, a regular lawnmower looks pretty dangerous too. | 13 | 13 | [

It is also interesting that you set the time by rotating the little dial on the top right. While it may be easier to set the time that way, it seems that it would be prone to getting nudged on accident.

By pounding a stake into the center of the yard and connecting a mower to it with a piece of rope, [Korey99] has achieve an automated lawn mower. He tied the self-propelled mower’s throttle bar down to make the machine run unattended. There’s no kill switch or any kind of

The projector displays information on the table top and the camera monitors the area for interaction. It can recognize your hand or objects such as a smartphone or headphones and react accordingly. An accelerometer in the laptop picks up tapping (we’d guess you have to tap pretty hard) and there is also support for gestures. This was presented at 2009 UIST and

] | Ah, the heady aroma of damp engineers! It’s raining in Silicon Valley, where the
2010 Embedded Systems Conference
is getting off the ground at San Jose’s McEnery Convention Center.
ESC is primarily an industry event. In the past there’s been some lighter fare such as
Parallax, Inc.
representing the hobbyist market and
giant robot giraffes
walking the expo. With the economy now turned sour, the show floor lately is just a bit smaller and the focus more businesslike. Still, nestled between components intended to sell by the millions and oscilloscopes costing more than some cars, one can still find a few nifty technology products well within the budget of most Hack a Day readers, along with a few good classic hacks and tech demos…
(Is that a promise or a threat?)
First order of business was to follow up on a couple of products we’ve covered in the recent past…
We
reviewed NXP’s mbed prototyping platform
in November of last year. While there’s no stunning new revision, the good news is that the
mbed
community is going strong and economies of scale have made it possible to trim the starter kit price from $99 back down to the original early adopter cost of $59.
Additionally, they’ve thrown together a project in just a few days to demonstrate the prototyping ease of the mbed platform. Reading like a checklist of Hack a Day clichés, the demo brings together
Twitter
, the Logo programming language, live web streaming,
servos and an Etch-a-Sketch
. You can read more on the
mbed blog
, or
watch the live stream
and participate during ESC show hours.
We also liked this little breakout board which adds the most essential interfaces to mbed:
MicroSD
, Ethernet and USB host & client. This was something quickly made for an mbed workshop, and while there are no plans to officially productize it, we’re told the unpopulated board might be available through
SparkFun’s BatchPCB service
in the future.
Many readers were put off by the web-centric development approach used by mbed, as well as the lack of a debugger. Another NXP entry-level evaluation product called the
LPCXpresso
provides an affordable ARM development kit from a more traditional angle.
The $30 LPCXpresso boards are available in Cortex-M0 or -M3 varieties and include an integrated JTAG debugger. The downloadable Windows development environment is based around the Eclipse IDE and GNU toolchain. With headers installed the LPCXpresso is
breadboard
-friendly and in fact shares the same pinout as mbed, so there’s an existing ecosystem of hardware to work from.
STMicroelectronics’ STM8S-Discovery made a huge impact
when we mentioned this $7 kit in November
, clearing out distributors in a matter of days. At ESC, ST was showing their new ultra-low-power 8- and 32-bit MCUs with demos powered by a cactus (a variation on the classic
lemon battery
), a cup of warm water sitting atop a
Peltier junction
, and a modest induction charger. (What, no
wind power
?)
A new version on the STM8S-Discovery based on the new lower-power chip should be available within a couple of months, and is expected to be similarly affordable.
(Left: the original STM8S kit that created the ruckus. Right: the forthcoming STM8L kit.)
At the
Texas Instruments
booth, the BeagleBoard XM was being demonstrated, which improves upon
its predecessor
in nearly every regard.
We’re told BeagleBoard XM stands for “extra MIPS,” “extra memory,” (and “extra money,” they joked). The XM does not replace the original BeagleBoard, but will be sold alongside it at a premium price of $179 when it ships in June. The XM includes a faster processor (1 GHz), more RAM (512 MB, and a 1GB model may be forthcoming), Ethernet, more USB ports and improved power protection. The NAND flash is gone, replaced by a MicroSD slot on the underside. The new board is slightly larger but retains the same mounting holes, so it may fit as an upgrade into some existing BeagleBoard projects.
Microchip’s
iPod/iPhone accessory development boards
that we mentioned last month
were on display. Unfortunately it appears one must be signed on with Apple’s “Made for iPod” developer program before these kits can even be
ordered
from Microchip, which really puts a damper on the fun for anyone who might just want to
tinker
.
Drifting further from product specifics and more into hacks and eye candy…
Product teardowns
have become a staple of tech culture. “
Zero-day
” and live blog teardowns of new products are particularly exciting. ESC’s gone one better, making a show of ripping into a product (if a rather esoteric one)
months
before its official release: a high-end Zircon AC wire detector built around a Microchip dsPIC and a bevy of e-field sensors. It’s like engineer pr0n!
National Instruments certainly had one of the most entertaining booths at the event. Rather than passively showing dry PowerPoint summaries and monitors running LabVIEW (their graphical programming environment for engineers and scientists), they instead presented physical demos and projects making use of the software. Some serious, others not-so-serious.
Hacks!
Remember Waterloo Labs’
iPhone-controlled car hack
? There it is! Rather, there it is
minus the actual car,
but with all the essential parts nicely laid out where we can observe the rig in action. At the other end of the booth, one can challenge “
RockBot
” to a round of
Frets on Fire,
not unlike
prior hacks we’ve seen
.
Hack a Day readers might be familiar with Digi International for their
XBee wireless modules
, such as used in Adafruit’s
Tweet-a-Watt
power monitor. Easily distracted by shiny things, we were initially smitten with this addressable LED
matrix
wrapped around their booth; not a product, just something to catch peoples’ interest:
As it turns out, there’s an added bonus hack
behind
the hack. Most of Digi’s booth displays could be controlled and monitored using their own custom
web apps
, so it was a simple matter of walking around with an iPod touch to run the show:
At the ARM pavilion, this “
Speedcuber
” was solving
Rubik’s cubes
in under half a minute. The camera and puzzle-solving logic comes from a Motorola
Droid
. Commands are issued over Bluetooth to a pair of LEGO Mindstorms
NXT
controllers to drive the motors that manipulate the cube.
Macraigor Systems
produces a line of JTAG debuggers…but to be honest, we (and pretty much everyone else passing the booth) nearly missed that fact, as we were all so distracted by their demo application involving one spectacular and elegant
Intel hexapod robot
:
We similarly fanboyed over
Cryptography Research’s
German
Enigma cipher machine
, as it was our first time seeing one
not
under lock and key in a glass museum case:
ESC Silicon Valley runs through Thursday, April 29th, and last we checked one could still
register for a free exhibits-only pass

"Misc Hacks"
] | [
"adc",
"potentiometer",
"voltage divider"
] | [Kevin Fodor] shares his method of
reading multiple inputs on one pin
of a microcontroller. The analog to digital convert function of the microcontroller is used to read a potentiometer but with some careful calculations a resistor network can be built into the circuit that provides a unique voltage value for each button pushed. The only real drawback is that the system cannot read multiple button presses at the same time. Theoretically up to ten momentary push buttons can be used but [Kevin] estimates that only four plus the potentiometer will work reliably.

"8800",

the Altair 8800 plus a lot of added computing power
. This PC case houses a Core i5 system but the front panel isn’t just for looks. He designed a PCB and resized an image of the original Altair front panel to end up with a fully functioning control interface. In the demo after the break you’ll see that the buttons can be used for power and reset and the LEDs can show random Altair-like patterns. But the interface can also works in conjunction with
an Altair emulator
to perfectly mimic the original Altair experience. This is a great way to sidestep the buyer’s remorse one might experience with
a standalone kit

. When we checked in with him last year he was showing off
an IR controlled dimmer module

The new design still uses an infrared remote but now it can turn two devices on and off again or toggle between them. Our favorite part of the build is that the PIC based device can learn the codes of whichever remote you choose, rather than having to rely on one specific type of remote. | 11 | 10 | [

The Cree LED bulb that he salvaged was going to be submerged in the water, so he had to do some workarounds to keep from over heating the biosphere. Read the project log for more details. | 8 | 8 | [

Take a few moments and watch this
3 axis rotating LED light display
fire up. The final effect of being an RGB glowing ball is nice, but we’re fascinated with the structure. There are tons of great detailed pictures of the assembly on the forum thread to feast your eyes on. Just getting power to the LEDs was a feat, he passes their power through 6 slip contacts. Parts were pulled from an old VCR and some old fans.

Control your tiny inexpensive
helicopter with a Nokia N900
. The chopper uses an infrared remote control, just like a television. Getting this to work was just a matter of figuring out the IR commands and writing an app for the phone to spit them out.
Fade to black; inconspicuously
Lost interest in your TV-B-Gone? Give it one last whirl by
throwing it inside of an old iPod
case. The dock connector hole is just about the right size for the LEDs and
the kit
fits nicely in the old 3G type iPods. With this kind of disguise it should be a lot harder to spot who’s messing with those TVs.
Surf your way to a cleaner house
This guy uses a roomba to clean his floors. The Wii balance board lets him lean forward and back to
surf the little bot around the room
. This seems a little more exciting than the exercise programs the board was originally designed for. [Thanks DXR]
G1 gamepad
[Tobias Weber] built a
gamepad for the G1
Android phone. He used an old Atari control, cut out two buttons and the d-pad, and glued them in a housing to fit the G1 keyboard. Each presses a button on the phone’s keyboard which can be mapped through the emulator software.
Social power monitoring
Here you see a very small portion of the
power meter installed in a Cafe
at UC Berkeley. It shows the energy usage for the building, separated into categories such as lights, power outlets, and coffee machines. This lets students know how much juice they’re draining by plugging in their gadgets. The color bar uses 93 ShiftBrite modules controlled by an Arduino. | 12 | 12 | [

Data is displayed on a 240×128 LCD display which will be the most expensive component to acquire. It’s still a lot cheaper than buying a commercially available oscilloscope, even if you
get a base model and hack it to unlock all the features

just received a new render farm
. It came in the form of a four-drawer file cabinet something akin to the popular
Ikea clusters
. Each draw holds four motherboards, power supplies, and hard drives and the whole cabinet will eventually add up to a 16-node cluster. Join in on the geeky excitement by watching the delivery and unpacking video after the break. We love it when
organizations share the details
on the hardware they use.

Apple IIe Twitter ticker to life
. [Chris Yerga] bought the decades-old machine for $20 at a flea market. Having just completed his
TweetWall
he decided to adapt the idea for the 1 MHz machine. He manually input a 50 byte bootloader that would let him dump programs into memory via the joystick port. From there he rigged up
a connection with a USB FTDI cable
. Now the images and text are processed by a modern-day machine and fed to the Apple IIe at 3600 baud. See this in action after the break.

This
video game controller
is a factory fresh VW. Much like the
racing simulator from earlier in the week
, the video game data is being displayed on the instrument panel. This takes us to a much higher level now because control for the game is taken from the car’s
CANbus
using and
ODB-II
connector. If you don’t speak in automotive jargon, that means that the sensor readings from the steering wheel, shifter, and pedals are being picked up and exported as joystick commands to the PC running the driving game. The only place the experience uses a substitute for the real thing is the sound, which is being played through speakers instead of emanating from under the hood. Looks like you just need to add a projector and screen to your garage in order to turn it into the hottest new gaming device. | 34 | 34 | [

connect a PlayStation 2 controller to a PlayStation Portable
. It’s a bit different from similar hacks as this adapter doesn’t require any hardware alteration to the PSP or the controller. To do so, a plug-in is used on the PSP firmware side of things. The adapter then makes use of video out and PS2 controller extension cables, along with an ATmega8 microcontroller to handle the signals between the two devices. We posted a picture of the guts because we like that king of thing but the finished project is nicely housed inside of a project box. See for yourself in the video after the break.

They share a lot of the same components (especially the expensive ones) but the first version is easy to swap out different fabrics and the second is a more permanent installation.

before… and if you look back, we mentioned the possibility of porting Android to the iPhone (even way back in 2008!). Well we are proud to announce that
The Future is Now
! The details are a little slim so far, but the iPhone is seen running a stock Android 1.6 install (Donut), and has support for Wifi, GSM networks, and even uses openiBoot to dual boot to the regular iPhone OS if you aren’t particularly committed. Right now the developers are considering it an Alpha version, and have provided all you need to perform this particular brand of Cult of Apple
heresy
. One catch though, the developers say that they only have it working on the 2G models, so sorry all you 3G(S) folks (for now). Dont get too down, and keep an eye open, something like this is bound to attract new talent to push the movement.

automated guitar pickup winder
with us. He built it for his senior project at Old Dominion University. Two stepper motors are used to wind the magnet wire around the pickup hardware. The unit is PIC based and about six minutes into the video (embedded after the break) you can see that he used wire wrapping for this build. Curious, one of the comments on
our latest Hackaday Links
mentioned that wire wrapping was rarely used anymore, but here it is anyway.
We especially like the limiting switches he’s using on the traverse mechanism. There are momentary push buttons on either side of a carriage which are depressed when a drywall screw in the sides of that carriage hits them. This makes for very easy calibration because the screw can be raised or lowered with just a bit of screwdriver work. Well built and documented, we’re sure he’ll get some high marks on this one.

Adding one to your project is pretty simple, just a matter of reading in analog data and interpreting it according to the datasheet. If you’re just starting out, here’s a tutorial on
how to interface an accelerometer with a PIC
microcontroller. They’re using an ADXL320 which
can be acquired
on a breakout board for about $30. The schematic and code are simple so even if you don’t intend to build the circuit (or want to use a different uC), this is easy to understand as an academic exercise.

The lead-acid battery supplied remarkable life between charges, but the vehicle only had one feature: a go button that routed juice to the bipolar motor. After the break we’ll look at his improvements to the drive train, steering, and cosmetics.
After cracking open the top hatch he wired in a double-pole double-throw switch that reverses the polarity of the motor. This way the switch to the left of the steering wheel can be toggled to shift from forward to reverse. The little red button above that switch controls the horn he added into the mix. Although not pictured here, he did some work on the steering column to increase the rotational limit of the steering wheel, which improved the ability to turn and steer.
The finishing touches were more cosmetic. The photo above shows the addition of two red LEDs for tail lights and at the top you can see the LEDs added to the decals of headlights. [Dan’s] improvements cost pennies but they make this

"logic analyzer",
"pic18f4580"
] | If you’ve got a graphic LCD lying around you can build this
four-channel logic analyzer
with a couple handfuls of cheap components. [Ronald de Bruijn’s] design uses a PIC18F4580 to sample up to four logic inputs at a maximum resolution of 2 MHz. He’s included the PCB artwork so that you can etch your own board. Having a logic analyzer around can really make your life easier, allowing you to
reverse engineer communication protocols
and troubleshoot your own design problems.

Open Zune Development Kit

). Sure, there was
XNA

OpenZDK is in its infancy, with only
one application
thus far (don’t worry, you can still use XNA apps too). But we wanted to give it a shout out and let the hacker community make this potential into a reality.

This video brought a smile to our faces. [Griffin Milsap] is
creating live music using an orchestra of solenoid
instruments. Each solenoid is set up to strike an object such as a bowl or mug. The trigger mechanism is a light sensor inside of a ping-pong ball. The collection of instruments is conducted by a motor-mounted green laser. When the beam of light passes by one of the ping-pong balls the photo transistor inside actuates the solenoid and a note is played. The pitches are quite a bit more random than the
Robo-vibe
, but it’s delightful to hear the results that [Griffin] has achieved. | 20 | 20 | [

"answers",

"hackaday",

"questions",
"safe"
] | Several people have been asking a similar question to,
“How do you at Hackaday keep track of and organize all your equipment?”
-[Jeff Allen] and others.
We have a variety of resources to help you keep track of your tools, equipment, parts, and supplies! Follow us after the jump for some tips for keeping your workspace clean and tidy.
First and foremost, we admit, we’re not the cleanest of bunches. We work on several projects at a time, receive ungodly amounts of mail and paperwork, struggle with dust and other allergens, all while writing wonderful articles. So please forgive us if our workspace is just a little messy.
So what can I use to help keep my parts orderly?
[Andrew Lybarger] asked us if
Spice Containers
would work, and was worried if the magnets would interfere with electronics. In short, we think they would work perfectly. Resistors, LEDs, etc should all be fine. We wouldn’t put our expensive ICs in there though, just to be safe.
For those that don’t want magnets, we suggest
clear dividable containers
. Or, my personally favorite for on-the-go hackers.
A tackle box
, its many holding areas for hooks and other things work great for transistors and caps. The bottom part of the boxes is usually quite roomy to fit a soldering iron (or two).
HAD writer [Devlin] prefers to keep all purchased components in the rail/tube/bag they come in, stick a label on and they’re good to go. Writer [Mike] goes a step further by keeping the purchase order and a spreadsheet on his PC with a list of parts and supplies, all it takes is a GREP search to find the right IC.
I just have too many tools, help me HAD!
If you have one or two items that can fit in the above mentioned tackle box, you’re set. But some here might have everything from a sledge-hammer to a pair of tweezers. There is no real easy way to say this, but buy a tool chest, or better yet
make one
.
How do I keep my workspace clean?
First and foremost, prevention. When you’re done with a project, put your tools away! We would like to slide in a little note here to mention not only a clean work environment, but a
safe one
.
For a computer workspace, nothing is worse than horrible amounts of cables creating a rat’s nest. Zip ties and a
little ingenuity
can go a long way.
What about the ungodly amount of paper work?
Whether digital or real, find a filing system. I know several HAD writers rely on
Google products
. And with Gmail, Calender, Documents, and more all interlinked, I’ve never lost an important file.
Outside of the digital side though,
accordion files
are great! We have several around the office for articles, finances, and more. For a lot of mail,
slot divided organizers
work wonders (And we always know where a pen is!)
Final note:
Don’t let your desk and work area get overfilled with tools and supplies in the first place. If you clean up after you’re done every time, you’ll know where everything is and will spend less time looking and more time hacking.
Here is where the fun begins.
We get to now ask the fun questions; how do you, our readers, keep organized with your equipment, tools, parts, supplies and other necessities of hacker-dom?
Want to ask us a question instead?
Send your questions to askHAD@hackaday.com for consideration. They will be chosen based on a complicated system of random number variation involving furry woodland creatures and how we feel at the moment that we read them. Do not get offended if you question does not get published. We get tons of questions already and we don’t intend to publish them all. | 34 | 34 | [

accelerometer
(with A/D converter), LED displays (and shift register). We were a little disappointed to learn of how much static the accelerometer produced, so measuring things such as impulse, energy, and pretty much anything
not

an under-board movement system
, a
Lynxmotion AL5A
robotic arm plucks each piece and moves it to the next space. He tells us that he’s using a Python script that he created to process the moves and decide what’s next. That must mean he’s using a webcam to capture the location of the pieces on the board. About half way through you can see the robot run into one of the pawns. We’d like to know if he has problems with picking up the pieces as the game progresses and they get further away from the center of each square. From what we can see, looks like a great job! | 22 | 22 | [

Finally, a good use for those EEG headsets. [Andrew] has set up
a system that will turn his TV on and off if he focuses hard enough
. He’s got the software set to trigger an IR LED when the “strength” gets high enough. When the action starts, around 4:30 in the video, you can see that when he raises his arm the meter on the screen begins to raise and the TV turns on. Though not immediately useful, we can’t help but get a little excited seeing him literally turn his TV on with a thought. | 31 | 31 | [

“How to control a web cam via internet,
i want to use it for security reasons, always out of the house and my PC connected want to open the cam from time to time to checkout if something wrong!!”
– [Mohamed Saleh]
What a fun project we thought! And so many different ways of tackling it. Find out what we suggested to [Mohamed] after the break.
Initially we wanted to create an extremely complicated setup, using a USB camera, server, webhosting, and a ton of scripts/programming to create a
rather sweet camera setup
.
But of course, complication breads problems, and while digging through our box of parts and supplies we stumbled upon an old
Axis 206 IP Network Camera
. What could be easier than all of the above built into one slick device!
The camera comes with an Ethernet cable, wall-wort for power, and a CD with instructions – we just threw the latter away and winged it, by finding out how to reset the device, then its default ip, we had view of the camera within our network in no time.
A simple port forward of 80 and we could view it outside of our network (so long as we typed in our IP). What we would recommend however, is setting up a DNS (
DynDNS
is great) service on a computer within the network that points to the cameras IP. That way the URL becomes
http://www.HADCamera.com
, a lot easier than 249.135.184.204:80. (Both are fake URLs sorry).
Taking it further, if you had a computer nearby you could setup a simple stepper motor and
control the position of the camera
.
This is of course our take on the matter and part of Ask HackADay is what our readers would do, so how would you setup a home security camera? | 75 | 50 | [

tutorial

The buttons are set to keystrokes and mouse buttons, and the accelerometer values are processed into mouse movement. Programmed to play
Portal
, we created a video showing how to use the device. You can see it after the break.
It was not quite as easy or quick as the typical PC gamer left hand: WASD, right hand: mouse stance. However, we can think of a number of other games that could be improved with the use of a device that, with a bit of hacking, could time keystrokes as the user needed. With a bit more hacking, the device could be made to brute-force passwords. What else would you do with this?

take a look at what Larry has to offer
on his site. He’s put together
a guide to VLF receivers
that is short enough to read and clear enough to understand with rudimentary knowledge of circuits. He builds
a simple receiver
as a working example and
a high-powered transmitter
that can put out over 2600 watts. Let’s face it, radio operators were the original electronic hackers. Get back to our roots and learn the ways of the transistor.

Winduino II
uses fins to pick up the movement of the wind and translate it into music. Each fin is attached to the main body using a
piezo vibration sensor
. The signals are processed by an Arduino housed inside and the resulting data makes its way to a computer via a Bluetooth connection to facilitate the use of
Max/MSP
for the audio processing. Included in the design is an array of solar panels used to keep the battery for the device charged up. Hear and see this creative piece after the break.

"pcb",
"pic18lf4553",
"picman",

] | [Ytai Ben-Tsvi] wanted a rapid prototyping tool that could be easily and cheaply built at home. He came up with
the PICMAN
, a breadboard compatible PIC based board that has everything you need to get the ball rolling. He’s using a PIC18LF4553 which has built-in USB support that can be used with a bootloader for programming. The board also features a voltage regulator for non-USB power sources, some indicator LEDs, a user-defined button, and a reset button. The chip is on the underside and a combination of through-hole and surface-mount parts make for a one-sided PCB that can easily be
etched using the toner transfer method
. You will need a PIC programmer to burn the bootloader firmware the first time but once that’s done this becomes a self-contained package. | 23 | 23 | [

"printable"
] | If you’re like us you’ve got quite a few prototyping tools that are bare PCB boards. If you’re using them a lot you might want to protect them with some type of case but the lack of mounting holes can make this difficult. One popular solution to this problem is to design a case for a perfect fit, then cut it with a laser or print it out of plastic. We’ve got examples of both.
[Stewart Allen] set to work designing
laser cut cases for the AVR Dragon and the Bus Pirate V2go
after seeing our post about
on-the-go prototyping
. We think this is especially important if you have an AVR Dragon as it’s been
known to bite the dust
if the bottom is shorted out. If you have access to a laser cutter you can download is DXF files and the models and cut your own.
If you don’t have a laser cutter but can get some time with a 3D printer check out the
Bus Pirate V2go printed case
and the
Arduino printed case

"disk",

] | This project explores the early days of television. Above you see a view from the back side of
a mechanically scanning television
. The black disk spins and the holes, aligned in a spiral pattern, create vertical scan lines for projected light to shine through. In this case, [Eckhard Etzold] is using red, green, and blue LEDs to create a color picture. As you can seen in the video after the break it does a pretty good job. The main problem being that the scanning disc on a
mechanical TV
has to be much larger than the actual image. How big would the disk need to be and how fast would it spin to produce a forty inch image? We still think this is a better method than
transmitting video data in parallel
.

Reader [Eric] sent us a powerfully informative, yet super simple
hack for the MindFlex toy
. Don’t worry, it’s not another worthless
shock ‘game’
, And it’s using an actual interface instead of the
built-in LEDs
.
With two wires for the serial protocol, and an Arduino, you’ll be able to view “signal strength, attention, meditation, delta, theta, low alpha, high alpha, low beta, high beta, low gamma, high gamma” brainwaves. While it’s not medical grade, it’s a lot more intuitive than previous interfaces.
The original intent was for a system called
MentalBlock
, but we’re wondering what would
you
do with brainwave data? | 59 | 50 | [

he built his own for about $5
. He re-purposed a hot glue gun which you can usually find at a dollar store. After removing the heating element he inserted the body of a syringe. The plunger has been modified to use a knitting needle inside of some plastic tubing. After taking the picture above he made an improvement by adding a milliliter scale to the plunger, allowing you to meter out the paste and also gauge how much remains. | 16 | 16 | [
