We pretty much don’t know anything about this POV device other than it uses 96 LEDs. We’ve seen
POVs with more LEDs
, but usually they aren’t packed in so tight. This thing looks almost capable of displaying low res movies. Wouldn’t this thing be cool, and probably dangerous,
in a hat
?

In this case, if the display used perhaps an RGB plasma display (think a single row of screen pixels, maybe 800 high) you could have a color POV display that could accommodate several viewers at the same time, provided they were viewing it from different angles. Apply this concept to, say, a multiplayer FPS game, only instead of dividing the screen into halves or quarters like on a conventional display, you could give each view angle it’s own POV “display”. It would have to spin very fast, and would require a pretty hefty amount of processing power to process the images, but it would certainly be a neat proof of concept.",

Every year, as it gets cold, many of us put our faithful two wheeled companion away for the winter. Despite that, there have been a veritable smorgasbord of bicycle related projects posted to instructables this last week. In honor of our human powered transportation, lets take a peak at a few projects.
Bicycle safety is always paramount. They can be fairly difficult to see compared to a car. There are many ways to make them easier to spot, such as
wrapping them in reflective material
, or adding
blinking tail lights
. Even if people do see us, they often have no idea where we are planning on going. To remedy this, we can always add
turn
signals
. It can also be hard to see where you are going at times. Adding a
head light
, or
helmet light
can really help. If you’re not a big fan of LEDs and want a little retro flair, you can always add an
oil lamp
.
For those who live in warmer climates, or just can’t give up their bicycles, you may wish to add some festive decorations.
Covering your bike in Christmas lights
doesn’t look too difficult, and a
CFL lit wheel
is a cheap way of adding some cool effects.

A Basic Stamp Supercomputer

Hobby super computer building isn’t something you hear about every day. This project is even more peculiar due to the fact that it is a
supercomputer built with BASIC Stamps
. [humanoido] posted some great pictures and detailed info about his project. We’re not completely sure what definition of
supercomputer
he’s using, but he states that it beats out the others in 10 categories. Those categories are: smaller, lighter, portable, field operable, runs on batteries, has greatest number of input/output, has greatest number of sensors/variety, lowest power consumption, lowest unit cost, and easiest to program. Those sound a little more like features than supercomputing categories to us, but that doesn’t detract from the fact that this is one cool jumble of wires.
You may be wondering what it does. Well, so are we. From what he says, it talks in Chinese and English and has a plethora of other input and output devices. It also displays status of its internal communications. Catch a video after the break.

[floe] wrote in to tell us about his
multitouch based thesis work
. While many projects have focused on the
hardware side of multitouch
, TISCH is designed to promote the software side. TISCH is a multiplatform library that features hardware abstraction and gesture recognition. This takes a lot of weight off of widget developers since they can specify known library gestures instead of writing the exact motions from scratch. Using TISCH also means a standard set of gestures across multiple widgets, so the learning curve will be much easier when a user tries out a new app. If you’re researching multitouch, check out this project and help improve the codebase.

RIM has decided to venture into the touchscreen phone market with the new
BlackBerry Storm
. Unlike other companies’ offerings, the Storm has a touchscreen that clicks when you press it. phoneWreck
disassembled the Storm
to see what
magic was involved
in the device. There’s not much too it, it’s just a big button. pW notes that the entire phone board is very compact mostly due to RIM using Qualcomm’s latest MSM7600 chip. Items like bluetooth, GPS, and USB are all included in the processor instead of appearing on the board as discrete components.
phoneWreck
recently launched and promises many future teardowns. They’ll be adding to their archive which already includes the
Motorola Krave
and the venerable
Nokia N95
. We’ll definitely be watching for their future releases.

The target release date may be over five months out, but the Ubuntu team is already pushing the
first alphas of Jaunty Jackalope
out the door. The new release is not for the weak and is intended solely for people who want to vet bugs and contribute to the project. The release is designed to bring Ubuntu back in line with Debian. One of the areas they’re working on is the ARM port (we saw the Debian version
on the G1
).

Working as quick as ever, the iphone-dev team have
updated the PwnageTool and QuickPwn
to work with the new iPhone 2.2 firmware update. The trouble with the new firmware is that it updates the baseband of the phone, which could potentially undo any
progress made towards an iPhone 3G unlock
in the future. If you don’t care about that, you can use QuickPwn to jailbreak your phone after the upgrade, so you can run any app you want. If a future unlock is important to you, use the PwnageTool to strip the baseband update out of the firmware update.

The Texas Advanced Computing Center has built one of the
largest tiled displays ever
. They arranged 75 30inch Dell displays in a 5×15 pattern. The overall the system has 36GB of graphics memory and 108GB of system memory. They intend on using the system to display very large data sets. If you think the size seems arbitrary, it is. They just happened to purchase five more monitors than the University of California San Diego.

Processing
, the open source programming language designed for artists and other creative types, finally went 1.0. Processing inspired numerous outpourings of creativity and beauty, from
interactive art installations
to
sound sculptures
. Improvements to Processing include OpenGL anti-aliasing, an extensible Tools menu, and the XML library included by default. You can read up on the
changes
or
download Processing
and start playing with it yourself.

Xbox 360 Arcade Controller

[weirdo] sent in this
sweet Xbox 360 arcade controller
project(
translated
). He really wanted an arcade controller for the new Mortal Kombat game. After noticing that the expensive retail arcade controllers were missing the trigger buttons, he decided to hack his own together. After dissecting the controller, he soldered in some break out boxes. This will allow him pretty easy reconfiguration. Wanting some additional customization, he added LEDs to the buttons. Most people add LEDs to the buttons, so that’s not a huge deal, but he also added one to the ball on the end of the joystick. That added touch almost makes us forget that this thing is housed in a pizza box. To be fair, he wants to refine the button layout for a while before he makes a final enclosure.
We covered a
very similar project
last year, but it has since disappeared from its original site. You may also remember the
slick Wireless PS2 arcade controller
from back in June.

[Aris] has quite a few
MIDI
devices that only have in and out ports. To chain together multiple devices, the MIDI slaves must have a “thru” port. Instead of daisy chaining, a better solution is to build a thru box to split the signal from the master. [Aris]’s
thru box design
uses an optocoupler on the input, which connected to 74HC14 hex inverting Schmitt trigger. The
schematic
shows three outputs, but there’s room for adding two more. A useful bit of kit for only a two hour job.

We heard some fear mongering that Apple had
released Apple TV firmware 2.3
to break
Boxee
and XBMC. It certainly was a side effect of the upgrade, but that
doesn’t matter now
since a new version of
ATV USB Creator
has been released to work with the new firmware. So, everything is essentially back to normal for the two media center programs.

The team behind
25C3
has published the first draft of
this year’s schedule
. The annual Chaos Communication Congress is happening December 27th to 30th in Berlin, Germany. There are plenty of interesting talks already in place. We’re spotting things we want to attend already: The conference starts off with
how to solar power your gear
, which is followed by
open source power line communication
. A
TOR-based VPN
, an
open source BIOS
,
rapid prototyping
,
holographic techniques
, and
running your own GSM network
are on the bill too.
We’ll have at least three Hack a Day contributors in attendance.
Last year
featured two of our favorite conference talks:
[Drew Endy]’s Biohacking
and the
MiFare crypto1 RFID crack
. We hope to see you there.

Notacon
has
just announced
their first round of talk selections. The Cleveland, OH area hacker conference will be celebrating its sixth year April 16th-19th. When we attended this year we saw talks that ranged from
circuit bending
to the infamous
TSA bagcam
.
Self-taught silicon designer
[Jeri Ellsworth] presented on FPGA demoing. [
Trixter
] covered his demo archiving process. You can find a
video archive of this year’s talks here
.
We’re really looking forward to the conference. [SigFLUP] is already on the schedule to cover Sega Genesis development.
Get your talk in soon
though; they’re already handing out space to the knitters.

People often accuse the computer of cheating when it is the opponent. This could be partially attributed to the fact that you don’t have a physical representation to identify with, the computer seems like an all knowing adversary that divines your moves from the aether. The
chief cook actually does try to cheat
though. They’ve trained it to play pong, all the while trying to distract you. Upon winning, it lashes out the insults pretty well too. We’ve seen the chief cook before. Last time, he was
learning to cook
. What will his next adventure be?

Make has
assembled a buyers guide
for the many different types of Arduino devices. The
Arduino
is an open hardware platform designed to make prototyping easily accessible. The design allows for other people to modify, expand, and improve on the base, and many people have started producing their own versions. The guide features a lot of the hardware we’ve covered in the past like the
LilyPad
,
Arduino Pro
,
Sanguino
,
Duemilanove
,
Ethernet Shield
, and
Freeduino
.
Out of the pack, the
Seeeduino
(pictured above) definitely caught our eye. It’s a low profile SMD design much like the Arduino Pro. They’ve taken advantage of the space saved by the SMD ATmega168 by adding more useful headers. In addition to the ICSP, you get the pins in UART order and an I2C header. Vcc is switch selectable for 3.3 or 5volts. The reset switch has been moved to the edge plus two additional ADC pins. Our favorite feature is the new spacing on the digital pins. Arduino digital pin headers have an inexplicable 160mil gap between the banks. The Seeeduino has the standard row for shield compatibility, but has an additional row spaced at standard 100mil spacing for use with protoboard. At $23.99, it’s competitively priced too.

I can run it on any kind of computer I want. I was also able to find a cheap ($23) linux compatible usb programmer. there are lots of code examples and appnotes. I have not and will not get an arduino as I’m allready set up for attinys and atmegas, I’m just not going to pay $20 to $30 a pop when many of the projects I do can be done on an attiny13 for $1.50 or an attiny2313 for $4. One thing to keep in mind is the arduino is a totally open design, not only is the firmware opensource (unlike a picaxe) but so is the hardware so if I wanted to make and sell my own arduinos there wouldn’t be a problem. this is why they are so cheap and popular. they are the cheapest way to get into microcontrollers (that will run on windows, mac or linux) and come with the total freedom that opensource provides; if you made a product based on an avr/arduino you would have a lot fewer legal issues mass producing it then if you had used a pic/picaxe. ’cause on the pic you would need a comercial licence for your (not so) free (anymore) compiler and the firmware/hardware for the picaxe.",

I believe it to be correct but someone else may say otherwise.PICAXE chips are based on the PIC chips but have Rev-Ed’s proprietary firmware installed on them.The difference between PIC and PICAXE is that PICAXE chips have a built in interpreter and boot-loader, whereas PIC’s don’t have any firmware pre-installed.This means that PICAXE generally is easier and cheaper to start off with, especially for education purposes, because although the PICAXE chips are a little more expensive than PICs, the equipment and software required is much cheaper (for example, a PICAXE prototyping board can be had for as little as £1.10ish which includes the serial interface used to download code to the chip, and the programming software is free).However, for batch production the PIC is better as you’re not limited to using Rev-Ed’s proprietary software, the costs will be lower when using a bulk batch of them, and the PICAXE chips are slightly slower than a normal PIC chip because of Rev-Ed’s firmware.For what it’s worth, I’ve used PICAXE a fair bit. They’re cheap and easy to program (you can even use flowcharts). However, I am planning on buying an Arduino Uno R3 board in order to compare them.I hope this rather lengthy post helps!",

Micromouse
competitions have been running in Japan since 1980. In all that time, the ruleset has remained essentially unchanged. The autonomous robot mouse navigates a 16×16 maze creating a map. It then determines the optimal solution for future runs. Current records are in the six to seven second range. Teams have had to find new ways to generate traction for better times.
Momoco08
uses a fan to hold the mouse to the track surface. Embedded below you’ll find a video of it solving the maze plus a photo of the vacuum skirt.

Although I am not aware of any car which uses a separate fan to achieve additional downforce, there are a number of sports cars that have fan blade shaped wheels to suck air from underneath the car.Also common in road cars are ground-effect bodies (for example, the Ferrari Enzo). These are also no longer allowed in racing and have a similar effect to an active fan. Compare photos of a Ferrari Enzo and a Maserati MC12 to see the difference between a car designed to take advantage of the ground effect and and a car designed to maximise traditional downforce.

Today, a Los Angeles jury acquitted [
Lori Drew
] of three felony computer hacking charges. She was
convicted of three misdemeanor counts
for accessing a computer without authorization. The 49-year-old Missouri resident posed as a teenage boy on MySpace and harassed her daughter’s estranged friend [
Megan Meier
], who then committed suicide. The case
came to our attention
in May because of it’s unorthodox use of the federal
Computer Fraud and Abuse Act
. Prosecutors charged that by violating MySpace’s Terms of Service, [Drew] had gained unlawful access to their computers for the purpose of harming others, an equivalent to computer hacking. While an interesting approach to cyberbullying, it would set a very dangerous precedent for anyone that had violated a TOS before (all of us). The case broke when [Drew]’s employee [
Ashley Grills
] testified that no one involved had read the TOS, that the hoax was all her idea, and that she sent the final message to [Meier].

USB Power From Your VGA Port

[gmgfarrand] needed an extra USB port to power some devices. Since he just needed power, and no data, he slapped together this quick adapter that pulls
power from the vga port
instead. While we’re not sure if this could possibly damage your video card if you pull too much power from it, we’re happy to see someone being original. That VGA port goes unused so often, this adapter might just make it a tad more useful.

Build A Portable NES

[1up] has posted his
portable NES
as an entry for the
Sanyo Eneloop contest
. We’ve seen some
really cool
portable builds, but this one has a complete step by step writeup of the process too. Many of these projects start with the little all in one devices that contain 99 games already. [1up] wanted to use original hardware so you could play any cartridge you could get. He used a complete
NES
and a portable
PS1
screen. The total project cost was roughly $130, if you don’t include all the stuff he broke in the process.
Not only does he make it portable, but also points out easy ways to improve your experience. One example is to disable the lockout chip. This was an anti piracy precaution from
Nintendo
. If the cartridge doesn’t pass this, it won’t play. Often, games won’t pass due to something as simple dirty contact. He explains all of this and takes you through the process of disabling the chip so everything can run smoother.
He has it all encased in a clear box. Some people prefer a more professional finish, but we have to admit that seeing the guts is pretty cool.

Our wallets are filling up with SIM and RFID cards that contain hidden information. Using our latest project, the
Bus Pirate universal serial interface
, we can dump the memory from many common smart cards. In today’s How-to, we show you how to interface common
smart cards
, and walk you through the data stored on a
FedEx Kinko’s prepaid value card
.
Background
The
FedEx Kinko’s
prepaid card is actually a SLE4442 smart card. There’s nothing secret about the SLE4442, it’s completely documented in the
datasheet
(PDF), and you can
buy blank cards on the web
.
The card is openly readable, we’ll be able to look at the contents without any sort of malicious intrusion. It’s protected from writes by a three byte password, with a ‘three strikes you’re out’ policy that renders the card useless after three failed password attempts.
Due to its wide-spread use, in Kinko’s and other capacities, the SLE4442 has been the target of several high-profile hacks. At the ’06 Toorcon, [bunnie] and [
Chris Tarnovsky
] hosted a discussion on the card. [Chris] examined the silicon die and suggested that shorting a trace might defeat the security measures. You can see high-resolution images of the die
on his site
. [
Strom Carlson
] went right to the source and
snooped the password with a logic analyzer
, as documented in his famous
’06 Defcon presentation
. The card even makes appearances in
artwork
.
We’re not planning on
maliciously intruding on the card
, but we can still look at the contents and demonstrate how to interface arbitrary protocols with our latest project,
the Bus Pirate
.

Grab the
SLE4442 datasheet
(PDF) if you haven’t already. The pinout is shown in the picture above. If you’re having trouble orienting the card, note that the large center pad connects to ground.
The card requires 5volts DC (datasheet page 27, table 3.2.2), we used the Bus Pirate’s handy 5volt supply. Interfacing at five volts is no problem because the Bus Pirate inputs are all 5volt tolerant.
A two-wire interface is used, with a clock line and bi-directional data line. We connected these to the Bus Pirate’s SDA and SCL pins. A third signal, reset, is required to initialize the chip; we used the Bus Pirate’s auxiliary output to control the reset line. The maximum clock frequency we can use to interface the device is 50kHz, with a 7kHz stated minimum (page 28, table 3.2.4:fCLK). The Bus Pirate’s raw 2 wire protocol runs at about 5kHz, but we didn’t have any problems interfacing the device.
The sle4442 has
open collector outputs
, and depends on pull-up resistors to hold the bus high. Instead of switching the data pin between ground and 5volts, it switches between ground and
high-impedance
states. High-impedance means that the chip exerts no state on the line, it lets it float, like a microcontroller input pin.
Each of the signal lines need to be pulled-up to 5volts with a 2K-10K resistor, the value isn’t particularly important. Without the pull-up resistor, we’ll never see anything but 0 (ground) on the bus because the sle4442 doesn’t exert a voltage of it’s own. A benefit of this technique is that the Bus Pirate, which only switches at 3.3volts, will talk to the sle4442 at a full 5volts, in compliance with the 3.5volt minimum voltage for a high level (datasheet, page 27, table 3.2.3:Vih).
Initializing the card
Before we can read data from the card, we have to initialize it. This is done with a standard ISO 7816-3 Answer to Reset (ATR) command. After initialization, we can read from the card using a simple two wire protocol.
Setup raw 2 wire mode
The interface shares some characteristics with I2C, but it’s not compatible. We used the Bus Pirate’s raw 2 wire bus mode to interface the device.
RAW2>m
1. SPI
2. I2C
3. UART
4. RAW 2 WIRE
5. RAW 3 WIRE
MODE>4
<– raw 2 wire bus mode
900 MODE SET
…
SPEED>1
<– speed setting is ignored in current firmware
901 SPEED SET
1. High-Z outputs (H=input, L=GND)
2. Normal outputs (H=Vcc, L=GND)
MODE>1
<– high impedance output type
9xx OUTPUT HIGHZ
402 RAW2WIRE READY, P FOR PULLUPS
RAW2>
The Bus Pirate has on-board pull-up resistors, but they only pull to 3.3volts. We must use external pull-ups to 5volts, as shown in the picture. High-Z output mode is compatible with the bus, normal outputs would put 3.3volts on the bus, potentially damaging something.
RAW2>l
<–configure MSB/LSB
1. MSB first
2. LSB first
MODE>2
<– LSB first
9xx LSB: LEAST SIG BIT FIRST
RAW2>
The card reads and writes each byte least significant bit first (datasheet page 10). We use menu option L to set the data mode to LSB first.
Send 7816-3 ISO answer to reset command
ISO 7816-3 “answer to reset” is a standardized command used among many smart cards. The ATR sequence is shown above: reset is held high, one clock pulse is sent, reset is released. The next 32 clock pulses (4 bytes) read a generic ATR header from the card. The header contains information about the card type and protocol. Multi-card smart card readers use this to determine how to read each card.
RAW2>@^arrrr
<– aux high (highz), clock tick, aux low, read 4 bytes
952 AUX HIGH IMP, READ: 1
4xx RAW2WIRE 0x01 CLOCK TICKS
950 AUX LOW
430 RAW2WIRE READ: 0xA2
<–begin ATR header bytes
430 RAW2WIRE READ: 0x13
430 RAW2WIRE READ: 0x10
430 RAW2WIRE READ: 0x91
RAW2>
We issue the command @^arrrr to the Bus Pirate. @ puts the auxiliary pin in high-impedance input mode, the pull-up resistor holds the reset at 5volts. ^ issues one clock pulse, with delay. a returns the auxiliary pin to output and holds the reset line at ground.
r issues 8 clock pulses and displays the returned bits as a byte. This is one instance where the protocol is incompatible with I2C. I2C includes an additional acknowledge bit between each byte, the sle4442 outputs 32bits consecutively.
Page 25 of the datasheet explains the ISO7816-3 header. It’s easiest to interpret in binary. Rather than convert everything to binary, we set the Bus Pirate to binary display mode and issued another ATR command.
RAW2>o
<–setup the output mode

<–0x10
430 RAW2WIRE READ: 0b10010001
<–0x91
RAW2>
The first 2 bytes are protocol header bytes according to ISO 7816-3 (datasheet page 25).
Byte 1 identifies the protocol type.
0b10100010
7:4 – Protocol type (1010=2 wire)
3:3 – RFU (0)
2:0 – Structure Identifier (010=general)
Byte 2, protocol parameters, tells us about the card if we didn’t have a datasheet.
0b00010011
7:7 – Supports random read lengths (0=no, read to end)
6:3 – Data units (0010=256units)
2:0 – Data unit bits (011=8bits per unit)
From the header we can tell that the protocol type is 10, a two wire bus. The card must be read all the way to the end before it accepts a new command. It has 8bits to a unit, and 256units; 256bytes total storage. The final two bytes are 7814-4 data, which seems uninteresting (see datasheet page 26).
Dump main memory (256 bytes)
Once the card is reset and the ATR bytes are read, we can send commands to the card. Commands are three bytes long; they begin with a I2C-style
start condition
, and end with an I2C-style stop condition. Start and stop conditions can be generated manually with \-/_\ and _/-\, but the raw 2 wire library also includes the shortcuts { and }. The start and stop conditions are the same as I2C, but they’re used at a different point in the transmission.
The read main memory command is
0x30
, followed by a read start address (
0
), and a third byte that doesn’t matter (0xff). After the stop condition, the card outputs data on every clock until it reaches the end of the memory. As described by the ATR header, no new commands can be sent until the card reaches the last byte of memory. Starting at read address 0, it takes 256*8 clock pulses to complete the read cycle.

{ issues the bus start condition. 0x30 sends the read address, 0 is the start byte, and 0xff could be anything. } sends the bus stop condition. 0r255 clocks in 255 8bit bytes and displays them on the screen. The card actually has 256 bytes of main memory, so we issue an additional read command to get the last byte and verify that the bus returns to high after the read is over. We can’t use 0r256 because the Bus Pirate doesn’t understand decimal numbers greater than 255 (we should address that).
What does the data mean?
We dissected the card according the datasheet, [Strom]’s Defcon presentation, and
this handy guide

<–The first four bytes are a repeat of the ATR data
0x46 0xFF 0x81 0x15
<–manufacturer tags, other junk
0xFF 0x01 0x4B 0x03 0x00

<–application identifier (Kinko’s?)
0xFF 0xFF 0xFF 0xFF 0xFF
<–all other bytes 0
The first 32 bytes are a permanently burned header with serial numbers, manufacturer codes, and other unique data (datasheet page 24). This header prevents exact duplication of cards, even if you have a blank card and a security code. Kinko’s didn’t have a custom serial number permanently burned into each card.
Now data….
0x7B 0x14 0xAE 0x47 0xE1 0x7A 0x94 0x3F
<– IEEE-754 value, $0.02
This is the value stored on the card, in IEEE-754 format. You can use
this utility
to make it readable. 0x3f947ae147ae147b=$0.02.
…8 bytes of junk…

<-not real data bytes
Dump protection memory (4 bytes)
The first 32 bytes of the data memory can be write protected. Each bit of the four byte data protection register (command 0x34) represents a byte of data memory. A bit set to 1 cannot be overwritten. We can read the data protection register and find out which bytes of the main memory are write protected. This is easiest to understand in binary, so we did this operation in binary output mode.
RAW2>{0x34 0 0} 0r4
<–command
410 RAW2WIRE START CONDITION (\-/_\)
420 RAW2WIRE WRITE: 0b00110100
420 RAW2WIRE WRITE: 0b00000000
420 RAW2WIRE WRITE: 0b00000000
440 RAW2WIRE STOP CONDITION (_/-\)
431 RAW2WIRE BULK READ, 0b00000100 BYTES:
0b00100000 0b11100001 0b00011111 0b11111000
<–data protection register
RAW2>
Each bit corresponds with one of the first 32 bytes of the card memory. If the bit is one, the corresponding byte is write protected. This register can be written, but only if you have the correct password.
Dump security memory (4 bytes)
The security memory contains a password verification attempt counter, and the three byte password. We can read the read the security memory without the password, but the password bytes will read as 0. The security memory address is 0x31.
RAW2>{0x31 0 0} 0r4
<–command
410 RAW2WIRE START CONDITION (\-/_\)
420 RAW2WIRE WRITE: 0b00110001
420 RAW2WIRE WRITE: 0b00000000
420 RAW2WIRE WRITE: 0b00000000
440 RAW2WIRE STOP CONDITION (_/-\)
431 RAW2WIRE BULK READ, 0b00000100 BYTES:
0b00000100 0b00000000 0b00000000 0b00000000
<–bytes
RAW2>
The attempt counter starts at three (0b00000111), and counts down to 0. When the counter reads 0, the card is essentially destroyed. We used two access attempts to test the password commands, this card has one try left.
Taking it further
We’d like to demonstrate all the capabilities of this card, including password verification and data updates, but we need to buy a new card with a known security code.
Due to the range of interesting smart cards cards out there, it might be handy to add an ISO 7816-3 ATR command macro and reply decoder to the Bus Pirate.

Adafruit has just put their
Uzebox
based console into production. The
Fuzebox
is an 8bit game console based around the ATmega644-20PU microcontroller. Full 256 color 240×224 resolution video output is provide by either a composite connection or svideo. There is an SD card slot on board for future expansion. The chip takes care of all the I/O, so you just need to write your game code in C on top of it.
The kit looks
easy to assemble
. Almost all of the components are through-hole. The video chip is SMD and comes presoldered to the board. The kit has two SNES controller ports included, but you can use
NES
ports too. There are three ways you can load your program onto the board: 6pin FTDI, ICSP10, and ICSP6.

The
DS1077
is a 5volt, 133MHz to 16kHz programmable clock source. The internal frequency divider is configured over a simple I2C interface, and the chip requires no external parts. Not bad for under $2. We used
the Bus Pirate
to test this chip before using it in a project. Grab the
datasheet
(PDF) and follow along.
DS1077
, $1.69 direct from Maxim + $10 shipping.
This chip isn’t available at any major distributors yet, but Maxim has them for under $2/each with a flat $10 shipping charge. This is an 8pin SOIC surface mount chip, so we made a small breakout board for testing.

We powered the DS1077 from the Bus Pirate’s 5volt power supply. Two resistors, R1 and R2,
pull-up
the I2C bus to 5volts when it’s not in use. Capacitor C1 is 0.01uF and C2 is 0.1uF, as recommended by the datasheet. Control pins provide some additional functions, but we bypassed them to ground during our test. Output1 is the primary clock signal pin.

We put the Bus Pirate into I2C mode (M, options: I2C, 100kHz). The external pull-up resistors hold the bus at 5volts, so it’s important to leave the on-board 3.3volt pull-up resistors off (default).

First, we broadcast the DS1077’s address and see if it acknowledges. The address of the DS1077 is 1011, plus three programmable bits (000 by default), and the read (1) or write (0) bit. We got an ACK, so we know that the circuit is working and our connections are good.

By default, the DS1077 saves all changes to the EEPROM. We don’t need this during testing, so we disable it by setting bit 3 (0b1000) of the BUS register (0x0d). The first four bits must be left as 0, the last three bits select the address to accommodate multiple DS1077s on the same I2C bus. See datasheet page 7.
I2C>{0xb0 0x02 0b00011000 0b00000000}
<–set the 16bit MUX value
210 I2C START CONDITION
220 I2C WRITE: 0xB0 GOT ACK: YES
<–DS1077 write address
220 I2C WRITE: 0x02 GOT ACK: YES

<–data byte 1
220 I2C WRITE: 0x00 GOT ACK: YES
<–data byte 2
240 I2C STOP CONDITION
I2C>
The MUX register controls the prescalers, CTRL pin functions, and frequency divider. We disable the prescaler and CTRL pins, and enable the 10bit frequency divider. The MUX register is explained on page 5 of the datasheet.
Specific frequencies are generated by dividing the 133MHz reference frequency through the prescalers and a 10bit (1025 level) programmable divider. The clock is divided by the amount specified in the DIV register,
plus two
. When DIV=0, the output is 133MHz/2=66MHz.
This scheme gives the best frequency resolution in low ranges, and no steps between 133MHz and 66MHz.
I2C>{0xb0 1 0b11111111 0b11000000}
<–DIV=1025
210 I2C START CONDITION
220 I2C WRITE: 0xB0 GOT ACK: YES

240 I2C STOP CONDITION
I2C>f
<–do a frequency count
9xx FREQ COUNT ON AUX: 16128Hz (16kHz)
<– DS1077 frequency
I2C>
We set all the bits in the DIV register to 1 for maximum frequency division. ‘F’ measures the frequency on the AUX pin, which is connected to the DS1077 clock output. With DIV=1025, the frequency is about 16kHz.
I2C>{0xb0 1 0 0}
<– DIV=0, 133MHz divide by 2
…
9xx FREQ COUNT ON AUX: 0Hz
<–66MHz, too fast to count
————-
I2C>{0xb0 1 0 0b10000000}
<– DIV=2
…
9xx FREQ COUNT ON AUX: 3339696Hz (33MHz)
<–133MHz/4
————-
I2C>{0xb0 1 0b00000001 0b00000000}
<–DIV=4
…
9xx FREQ COUNT ON AUX: 22192384Hz (22MHz)
<–133MHz/6
We can play with the divider and generate a range of frequencies. The output is always equal to the reference frequency (133MHz) divided by DIV+2. The Bus Pirate’s input pin is only capable of measuring about 50MHz, so the highest speeds don’t register. A future version of the Bus Pirate should include a gigahertz prescaler for high frequency measurement.
I2C>{0xb0 0x3f}
<–write E2 register
Finally, we can write the E2 register (0x3f) to save these setting in the EEPROM. The DS1077 will now return to these settings at power-on.
Conclusion
The DS1077 simplifies complex clock sources by moving a programmable oscillator and frequency divider into a single chip. It isn’t available from distributors, but you can buy it directly from Maxim. If you need better control of high frequencies, check out the
DS1085
with 10kHz steps from 133MHz to 8kHz. The DS1085L is a 3.3volt, 66MHz version
available at Digikey

[jelengar] liked the ease of use of the Arduino, but wanted a much higher pin count. He set about converting the
ATmega Controller for use with Wiring
, the code that the Arduino IDE is based on. The ATmega128 in the controller features 53 pins as opposed to the 11 on the Arduino’s ATmega168. You also get
128kb of memory
. The process is fairly simple; you just need to add the appropriate crystal. You can also add a switch to trigger the bootloader and a status LED.

While the iPhone 3G included several new features that its predecessor lacked, one thing it did not include was a dock. Instead of shelling out $30 to buy Apple’s iPhone 3G dock, [Roland] and the folks at Geeky-Gadgets.com decided to design their own
cardboard iPhone dock
. While this doesn’t include any fancy features like dock connectors or audio line-outs, it looks like a quick and budget friendly way to give your iPhone 3G a place to charge and sync.

WEEE Man is an art display
that has been roving around England. No, he doesn’t walk or talk. He is here to remind us of how wasteful we can be. Hackers rejoice, we’re part of the solution. It also doesn’t hurt that he is Seven Meters tall and over three tons. WEEE Man looks awesome, but are we the only ones that spotted stuff and thought “ooh, I could have used that for a cool project.”?

Zap New Life Into Ni-Cads

Apparently you can
revive dead Ni-Cad batteries
by zapping them with high voltage. Some people have used
welders
in the past, but many of us just don’t have access to one. This project shows you how to hack a disposable camera into a battery revival device. This could be very cost effective. A single regular AA battery could revive many Ni-Cads. Remember, this doesn’t charge them, just makes them able to be charged again.

One would then just momentarily (as in brushing a wire to complete the circuit for, like, a ms) complete the circuit where you’d have the + of the BigBatt connected to the + if the NiCd, and the – of the BigBatt connected to the – of the NiCd.This high-amp short circuit tends to burn out the dendrites that prevent the NiCd from accepting a charge.Cautions:Beware hydrogen gas from Lead Acid (BigBatt) type batteries, esp during/after charging them.When you brush the wire to complete the circuit you’ll get a spark. This is part of the fun.If the NiCd begins to feel warm then stop immediately.I sometimes brush a few times, for good measure.This ‘revival’ process works very well to revive a dead NiCd that won’t accept a charge from its charger.

Rocket Camera project
. It really isn’t much that we haven’t seen before, but we thought many of you would be feeling the effects of gravity a little harder today. So when your belly is stretched to its limits with
Turbaconducken
and you don’t think you can stand, take a little flight with [jordan]. Careful you don’t lose your lunch on the way back down though.

[Moritz Waldemeyer], a
favorite artist of ours
, has a brand new project. He went wanting to design a 3D version of the game
Operation
. The piece he ended up with is called
Keyhole Surgery
. It’s essentially the
laparoscopic
version of operation. The player guides a metal key through the passages of a translucent block while attempting not to touch the walls. A counter on the side displays how many hits it has detected. The player with the smallest number wins. We love the modular potential of this project: the number of layers could be increased, the order could be changed, and more.

A team of five UC Berkeley engineering built this impressive Rubik’s Cube solver. The CuBear is a giant transparent cube with a servo attached to each face to rotate the cube’s six faces. The user can either scramble the cube using computer controls or show the faces of a scrambled cube to the onboard webcam, and the machine will replicate it. While scrambling the cube may take many moves, the computer calculates the shortest number of moves to solve the cube before proceeding. Team member [Dan Dzoan] is quite a fast solver himself, as you can see at the end of
BotJunkie’s video
embedded below.

Advanced Beauty
is a collection of 18 “sound sculptures” pairing artists and programmers to create a collaborative work visualizing sound. The styles run a broad range from fluid simulations to manipulating cell animation. The demos were built using
Processing
. While all of these were built using human input, we see potential for them to help improve standard visualizers. Hopefully, to bring out more information about what’s actually being played. Below is just one of the videos in the series. You can find
more on Vimeo

[Mario Mauerer] and friends were commissioned to build this
2m persistence of vision display
(translated) for a party (in a hight-voltage lab no less). Dubbed “Display from Hell”, it uses 100 blue SMD LEDs to generate the
POV
images. They’re connected to an ATMega64 via shift registers. Their target speed is 600rpm for a flicker free image, which means the propeller tips are moving at 140mph. The board can be updated wirelessly via IRDA and plans for adding SD storage are in place. You have to see and HEAR this thing in the video embedded below.

File this one under: “Wow, that’s even possible?” xbox-scene hacker [RDC] has been hard at work
converting his Xbox 360 to slot loading
. To start, He removed the slot loading drive from a blueberry iMac G3. The loading mechanism is the top half of the drive. He split this off and married it to the reading mechanism in the Xbox’s Hitachi drive. The difficult part came with getting the drive to properly signal when it had a disc. He put together a custom circuit to do the detection and has a thorough description of
how he solved the problem
.
[Thanks, bic]

Reader [Julian von Mendel] and his team built this
tennis ball fetching robot for a competition
(translated). The first version used distance sensors to locate the tennis balls for pick-up, but they changed to a
camera based approach
. The robot has three omniwheels and is designed to calculate the shortest path to the ball despite orientation since it can rotate while traveling. The wheels are monitored using rotation sensors from PS/2 mice. The control is provided by 3 Atmel microcontrollers that communicate via SPI. The multiprocessor design is fairly generic and could be reused for a different style of robot. While their robot performed fairly well, there were some shortcomings. The limited storage space meant frequent trips to drop off balls. The tilting bucket kept them from picking up tennis balls that were against the wall. Also, the bot had to be disassembled for battery swaps. The project is very well documented and they’ve released all of their control code. You can see the robot retrieving a ball after the break.

We’d never discount the beauty that is the
SpokePOV
bike wheel kits, but if you want to just turn your bicycle into a blinding blur, [depotdevoid] has the solution for you. He had a
CCFL
tube left over from an abandoned LCD monitor backlight repair, and decided to see
what it would look like as a wheel light
. The result turned out fairly well. He had to figure out how to mount the 8 batteries plus step-up board. He says the extra weight isn’t really noticeable and the light output is quite bright. CCFLs can be incredibly fragile, so take care when you do the actual mounting.

I’m no expert at turbines, but it seems like that should work. You could then either set that up to charge a battery pack or run the output through a voltage regulator for a maximum of 12 volts plugged directly to the voltage step up board.Of course, a simpler solution (that might actually be lighter weight in the long run) would be to wire this up for 10 AAA’s instead of 8 AA’s and use rechargeable 1.2 volt batteries instead.-depotdevoid",

Here’s yet another robot hoping to dominate the human race through the power of ROCK.
Cythbot
was built to demonstrate Cyth Systems machine vision systems. The device uses a camera to watch the Guitar Hero monitor and identify notes for button presses. The strum bar is then triggered after a delay. The notes are identified solely by pixel intensity since star power can cause them to change shape and color. All button presses are done using pneumatics. The whole system is self-contained and doesn’t require a separate computer for processing. Our favorite part is that the controller remains completely unmodified and the industrial light tree used to indicate notes. The team says that the pneumatics aren’t quite fast enough to hit 100%,
unlike some humans
. Video of the bot in action after the break.

oomlout has posted some interesting
plans for a simple robot
. It’s based around an Arduino and is a platform similar to the Parallax
Boe-Bot
. The Arduino sends PWM signals to continuos rotation servos that drive the two main wheels. All of the structural components are laser cut from acrylic with slots to hold standard hex nuts. It’s an interesting technique, but the design has a lot of potential for improvement. Right now it uses two different power supplies and a breadboard for simple connections. From the video below, you can see that the balance could be improved as well.

There is no doubt that [Johnny Lee] is the authority on Wiimote based projects. So, when he compiles a list of his
favorite Wiimote projects
, we definitely pay attention. He’s organized the list as a progression of the unusual. By the time you get to ‘
Chicken Head Tracking
‘ at the bottom, you’ll be adequately prepared. You’re bound to get some inspiration from the list even it’s building a
pigeon guided missile
.

We’ve been following [glaciawanderer]’s CNC build for quite some time and he’s recently added a few upgrades to make for an
even more interesting machine
. He’s been trying out new bearing blocks, anti-backlash nuts, and z-axis plates hoping to get some improvements. In the case of the bearing blocks, he went back to the older style because of the added safety and smoother movement. The final addition he made was a dust collection system. It’s just a couple support hoops and duct tape, but it should keep dust out of the threads and rails.

I I did move the entire z axis rather than just the plate then I’d have 5.5 inches of z travel.The reasons I don’t use move the whole z axis are:1) It’s more complicated method since I am currently able to mount the x axis lead nut to the z axis and if I moved the z axis I’d need another plate to handle this.2) It is theoretically less rigid. Not sure if this would affect the real world system.3) 3 inches of z travel is enough for me so I’m just going to follow KISS. One reason 3 inches is enough is because any router bit that can cut more than 3″ is extremely expensive.",

YouTube, purveyor of some of worst looking flash video is
finally getting their act together
. We
posted the other day
about embedding videos using &fmt=18 to get higher quality YouTube videos. It seems the awesome knob has now been turned up to &fmt=22. All of the previous tricks should work, just use 22 instead of 18. This all depends on the highdef version being available. Now they just need to get rid of the grainy preview images.

Here’s a video of a student submission to the 2008 NHK RoboCon competition. The robot, who vaguely looks like a giant lego minifig, is controlled via a suit. The robot mimics the moves of the wearer. We can’t help but have visions of the clown from
F/X2

File this one under “stuff that doesn’t make sense”. Someone put a
Nintendo 64 into a Wii
. Yes, we know you can download those games with virtual console. Maybe they did it just to look cool. Maybe a Wii case just happened to be laying there when they got some Nintendo 64 guts. Whatever the reason, it is for sale on
Ebay
.

[ricosgoo] wanted a way to stand out at his graduation. We think he succeeded with his graduation
gown VU meter
. After putting the circuit together at the last minute, he made a mounting harness out of duct tape. The electronics hang like a sash, placing the bulk under his arm where it won’t show through his gown. He mounted a mike towards the neck line so it reacts best to his voice. It was a hit, apparently strangers would come up and make noise just to see the meter go off.

If I had thought anyone would be worried I would have probably got an “OK” from someone ahead of time. UAT actually used to advertise on Hackaday as “hackerdegree.com”. Not sure if they still do. If you are into networking/security/webDesign/gameDesign/robotics/forensics then I would suggest you check their main site @http://www.uat.edu.@EdZ: Yea, for some reason jumping the wires on the bottom of the board seemed like a good idea at the time. Why? I don’t remember. I guess it’s just because I wanted to have access to the potentiometer and I wanted to be able to remove the ICs if I needed too later. I didn’t want to end up having wires get in the way. Thinking back, though, it would have been easier to just solder them on the top. There would have been a lot less wire melting!@will: If by “useless” you mean “has no real purpose other than to make people think ‘oh cool!'”, then I agree with you lol. I did it just to do something different, and as I said on the curious inventor site I was going to do it anyway in shirt form. Graduation was really just the motivation I needed to get this project done.There are a lot more details on my blog along with some other projects I’ve done @ richardosgood.com/blog . Unfortunately, due to an iptables mishap, the site is down right now. I should have it back up when I get into the datacenter either tomorrow or the next day.Thanks for showing interest!",

Faster Browsing With RAM Disks

A coworker approached us today wondering if they could get a performance boost using
Samsung’s newly announced 256GB SSD
. Most of their work is done in browser, so we said “no”. They’d only see benefit if they were reading/writing large files. Their system has plenty of RAM, and we decided to take a different approach. By creating a filesystem in RAM, you can read and write files much faster than on a typical hard drive. We decided to put the browser’s file cache into RAM.
We installed the
Espérance DV
preference pane in OSX to facilitate RAM disk creation. It’s really simple to setup. Just select how much space you want to dedicate to the disk and create it. You can have Espérance DV recreate the RAM disk on start and even have it automatically restore from a disk image. There is a check box for moving Safari’s Web Cache to the RAM disk, which creates the necessary symlink. You can also use it to speed up Xcode builds. Moving Firefox’s cache is fairly simple:
$ rm -r ~/Library/Caches/Firefox
$ ln -s /Volumes/RamDisk/Firefox ~/Library/Caches/Firefox
Since the browser isn’t having to hit the hard disk on every page load anymore, the performance is much snappier.
Xbench
says our random reads from RAM are now 86.19MB/sec instead of 0.61MB/sec when the cache was on the hard drive.
We immediately began looking for ways to get the entire OS into RAM;
Tin Hat
is a version of Linux that does that.
We’re very happy with the results of our RAM disk browser upgrade. Let us know in the comments if you’ve had a similar experience doing this in Windows.

Tellart
turned an iPhone into a
duiPhone
with its latest
Sketchtools
kit. Combine a 3G iPhone, an ordinary store-bought breathalyzer, and the
NADA Mobile
, which consists of a communication board, sensors, and actuators, and get a useful iPhone application. Blow into the mouthpiece, and the iPhone will inform you if you can safely drive, or if you should call a cab.
We’d like to find out more about the NADA Mobile, since it looks like it could be the start of a lot of fun projects. It’s the latest of Tellart’s Sketchtools line, which can only be accessed if you work with Tellart as a consultant, or if you work with them to organize a workshop for your organization.

German designer [Michael Schoner] of
NL Architects
turned an
ordinary street bench into a public sound system
that can be accessed by passersby with
iPods
and cellphones with Bluetooth. Boom Bench features 60 watt co-axial speakers, two subwoofers, and a bass shaker in the seat that’ll allow you to feel the vibrations of your music choices. It was on display in Amsterdam last month for the
Urban Play
event. It remains to be seen whether this new urban development will make your daily wait for the bus more entertaining or aggravating.

Add lights to your graphing calculator
. Do it now. [Sil3ntP8nd8] added some, and seems to have done a decent job. They are spread around the back, supplying a nice even light on, well, on whatever is under your calculator. It may be difficult to see too much detail though on account of the water marks. You have to protect your intellectual property though. This almost compares to the
DS LED monstrosity
we covered recently.

[Lynne] had this crazy idea to build
a piece of clothing that would give you feedback about your surroundings using sonar
. She started with a carefully selected thrift store jacket. She wanted something that looked good and also provided plenty of places to hide electronics. She used the
LilyPad system
, with a vibration pad and a sonar range finder. When the system detects an object within a certain distance directly in front of the wearer, it warns them with some vibration. Not only is it practical, it looks pretty cool too. Did we mention she designs clothing?
She notes, in the comments section, that while it can detect an obstacle, it cannot detect a void. How could she detect a drop in the floor or a step down?

“Interplanetary Internet” Passes First Test

NASA
just completed the first
deep-space test of what could one day become the interplanetary internet
. Images of Mars and its moon
Phobos
were sent back and forth between computers on Earth and NASA’s
Epoxi
spacecraft. Instead of
TCP/IP
a new protocol, named “
Disruption/Delay Tolerant Networking
” (DTN) was used. Information is only sent once with DTN, and stored at each node until another node is available to receive the information. To prevent hackers from interfering with the network, information that is transmitted over DTN is encrypted. The team at NASA is hoping to get the protocol accepted by the international community and setup a permanent node at the International Space Station next year.

[Anupam Pathak] knows how jarring it can be to wake up to a traditional alarm clock. He decided to
hack an alarm clock
so that it would open the shades in his room to allow in natural light. He found the pin that went high when the alarm was triggered and used that to signal an ATtiny45. The microcontroller activates a servo connected directly to the blinds. He has switches on the side of the clock to manually control the blinds and to cut power to the audible alarm. Video embedded after the break.

Hacking at Random
, an international technology and security conference, has just announced the dates for their 2009 event. The four day outdoor technology camp will be held August 13-16 near Vierhouten, Netherlands. HAR2009 is brought to you by the same people who held What the Hack, which we
covered in 2005
. They’ve done this every four years for the last 20. We’ll be sure to attend. We
loved
CCCamp
in Germany last year and plan on attending
ToorCamp
in Seattle this year too.

Google recently updated their
Google Mobile App
with a couple new features. Voice Search automatically starts listening when you raise the phone to your ear. Just say what you’re looking for, and it will poll Google and return the results. The app leverages Google’s voice recognition engine, which they’ve been training with
Goog-411
. [Andy Baio] has been experimenting with audio transcription and was
curious what the new app was doing behind the scenes
. He started by sniffing the packets as they traversed his network. Unfortunately, the size of the data packets transmitted is so small that he’s almost certain he’s missing something. He’d appreciate any help in this endeavor. Part of the problem might be Google getting special treatment and
using undocumented iPhone SDK features
.

The Guardian’s technology department
hosted its first Hack Day
last Thursday. Developers were freed from the drudgery of their everyday jobs to make fun toys and tools. Many of the hacks that developed played around with the website, like the
Guardian commenter blocker
, or the
Guardian Button integrated into the Google Toolbar
. We liked the
Guardian Politics Page LED Swingometer
, created by [Tom Armitage], which scanned the Guardian’s politics RSS feed for mentions of “Conservative” or “Labour” to yield the “swing” of a page to an Arduino. We wanted to see more of the
Java-enabled Robot Dude
. You can track Fhe Guardian’s Hack Day activity on
Twitter with the tag #ghack1
or check out their
photos on Flickr
.
If you want to participate in a Hack Day,
Last.fm is hosting one
this December.

Animated LED Keyboard

[Brian] made this
really cool LED keyboard
. He started with a
Deck Legend Fire
. When he got it, he realized that every key had its own LED, but the entire unit was either on, or off. He just couldn’t live with that and decided to start hacking into it to make each light individually controlled. He found a perfect empty space in the back of the keyboard and designed custom PCBs to control his lighting. he notes that he spent 12 hours of cutting and soldering wires to each of the lights in the keyboard, that doesn’t include the PCB construction.
In the end, he had a fantastic looking keyboard that had cool effects like heat mapping and idle animations. All stock features still work and it looks almost entirely stock. The only obvious difference is the fact that it has two USB cables coming out of it due to some issues with his KVM switch not detecting it.

[Mark] had a broken TI-83 graphing calculator and an overwhelming urge to play Pokemon in math class. The solution to his predicament, obviously, is to
hack a GameBoy color into the body of his TI-83
. He gutted the calculator and connected the front buttons to the contacts on the GameBoy. After some cramming and taping bits together, he got it all working. Now he just needs to find a way to make the cartridge a little bit less conspicuous.

Our fascination with
multitouch
is fairly well known, but it expands even further to cover all sorts of man machine interaction. Embedded above is a tech demo of
g-speak
, a spatial operating environment. The user combines gestures and spatial location to interact with on screen objects. If it seems familiar, it’s because one of the company’s founders advised on Minority Report. We doubt all this hand waving is going to catch on very quickly though. Our bet is on someone developing a multitouch
Cintiq
style device for people to use as a secondary monitor. It would bridge the gap between between our standard 2D interactions and gestures without making a full leap to 3D metaphors.

We mentioned Pulse Width Modulation (PWM) when talking about [sprite_tm]’s
marquee control
. It’s a method of power control. While [sprite_tm] did it in software, [Afroman] sent along a very straight forward
introduction to PWM using just a 555
. Check out his video for coverage of this fundamental electrical design technique.

[Rory Hyde] and [Scott Mitchell] are exploring several projects that add more information to public spaces. The first is the
Spoke-o-dometer
a persistence of vision device that can display
bicycle
speed and distance traveled. To develop the device, they first bought a few POV kits to test out. They decided to build their version using an
Arduino
. Once they had the display proof of concept working, they added a hall effect sensor like the
SpokePOV
so they could determine speed and orient the display. Check out their project site for plenty of example code and development details.

Not all hard drives fail the same way. DataCent, a data recovery service based in Canada, has an impressive
archive of failing hard drive sounds
. If you’re ever in doubt about whether your hard drive needs help, this is your guide. From bad heads to stuck spindles, bad hard drives click, grind, hum, and scratch. It’s almost musical in its regularity. Who will be the first person to string of these samples together into a ringtone or techno song.

After being inspired by our previous posts on a
microcontroller-powered missile launcher
and the
wireless fireworks controller
, [Adam] at
Additronics.com
decided to build his own
microcontroller launcher
. He combined elements from each of the prior projects, and included some of the advice from the Hack a Day comments. His multi-rocket/fireworks launcher is configured with an
Arduino Diecimila
, and requires a whole boatload of batteries. [Adam] claims there’ll be another video at New Year’s of the microcontroller in action, which we’re definitely looking forward to watching.

In a previous job, [sprite_tm] was responsible for wrangling many different LED text ad marquees. The hardware was fairly simple and he always figured they could be pushed much further with a little work. He recently acquired ten 32×16 LED displays a decided to
see what he could do with them
. By the end of the project, he had full motion video running on the display. This is a great project to read up on if you’ve ever wondered about LED matrix displays. He starts by reverse engineering the electronics on the board. He then attached an ATmega88 to drive the display module. Multiple display modules were daisy chained together over serial. The article covers PWM control and refresh timing as well. Check out one of a few demo videos below.

[Matthew] sent in this slick project where he made a
Mac pro Ultra Mini
. He received a
MacBook
that had been killed by water. He took it apart, re-soldered some connections and was able to get enough of it working to be a decent multimedia machine for his tv. To make it look nicer, he found an external drive case that looks like a tiny
Mac Pro
. After a little bit of grinding, cutting, and zip tying he managed to get all the pieces inside the case. We’re always happy to see hardware salvaged, and to see it transformed to a fantastic looking useful machine is a bonus. Good job [Matthew].

Scratch input allows us to use
solid surfaces as an input devices
by capturing the sounds they produce. Using a stethoscope and a high pass filter, they capture the unique sounds of specific gestures. Custom software then translates this to actions for applications. The video shows some really cool stuff, like turning an entire wall into an input device. It goes around corners and past doorways. They even talk about potential using your clothes to capture input.

You would probably need to use multiple mics with different phase orientations at each position in order to be able to determine an actual angle to the point at which the gesture was made. I’m not very clear on the physics here, but some experimentation would probably show whether this has potential.A related (but somewhat simpler) project created by my friend and fellow member of DorkbotPDX, Collin Oldham, is his Clapboard:http://homepage.mac.com/coldham/klang/clapboard.html",

I do actually agree that 3 may work somewhat better.Do you know how the police (and other companies) can track cell phone locations? A call tower, or antennae, can determine the range from itself to a point, the phone. This forms a circle of where it could possibly be. A second antennae can form another “range circle” and narrow it down to 2 points in space. A third can be used to determine the exact point the cell phone, rather than 2 possible ones. My old math teacher actually was in the FBI.Now apply that logic to scratch input, but with much shorter ranges. It could be done with 2, but 3 would be more accurate. 1 however, just seems overcomplicated to me.",

I worked with them at elo for a small contract job once.Basically it’s just two microphones on a sheet of glass. A machine taps the glass in a matrix and the stereo sound profile is recorded, maybe classified into an FFT fingerprint. Then the incoming audio is compared against a database of stored profiles. A normal sound card is enough to get good resolution, though of course Elo’s hardware is optimizing the signal and ADC so you don’t actually have to plug a line in to your computer. All the real work is in the software driver; optimizing the search for known patterns, rejecting noise, making it all fast enough for instant touch response.You can download whitepapers with more in-depth discussion of the technology on Elo’s website.",

Peripheral manufacturer Datel has been hard at work attempting to crack the
PSP 3000
since its release. They’ve developed the Lite Blue Tool battery to
force the PSP into service mode
so hackers can run any arbitrary code they want. According to MaxConsole, Datel performed a silicon level investigation of the PSP’s chips to determine how to break into service mode. This means they decapsulated the the chips and reverse engineered any cryptographic protections. We’d love to hear exactly what chips were being used since some are
fundamentally flawed
.
Silicon hacking
has always been a favorite topic of ours and we suggest you check out [Chris Tarnovsky]’s decapsulation technique to
learn more about it

I know most of you people, if any are reading this, will want to know the magic behind the trick, I tell you that we will not share it for three main points:1.- The psp 3000 is sony’s final hope to keep the psp alive. Game makers aren’t willing to put up with all the piracy around so they will definitively stop making games for the psp if the word of its hacking spreads out.2.- There aren’t homebrews that run on psp 3000, or if there are, i don’t know about their existence, and therefore, aren’t supported by our customzised firmware. What I can do with my freshly hacked psp 3000 is playing ISOs, CSOs, because the firmware we have developed supports it.3.- If it’s running around the internet, sony will eventually find a protection and send a firmware patching their flaw, preventing someone else to do it themeselves.The only thing we wanted to achieve was that, playing ISOs and CSOs, the rest of the stuff is just not as important, for us.Currently there are 7 psps 3000 that have runed our KnD (kill n destroy) which is a downgrader that can run on the psp 3000. It will take it all the way back to 1.5 OFW. then we developed the first ever choliware 1.0 which supports ISO and CSO.Pretty cool huh?.We don’t expect people to understand let alone accept our final deccision of keeping it a secret, but listen to this.There is hope.If 7 kids from Peru could take sony’s so called, unhackable psp, and hack it, WHAT’S STOPPING THE GREAT MINDS OF PSP HACKING LIKE DAX OR C+D? guys, we worshipped you, but i think this time we beated you to the punch.On the other hand, you guys might have already done it, but like us, are holding the information back.either way, we want to encourage the average psp player to start investigating. eventually someone foolish enough will hit it and share it.ReptARSAU_INsaRtFsoulGari,#4EicoSANA_popSexYAPPEAL090Juan_Valdez2.0",

As for hackers, are they really hacking? it’s their property, they can use as a frisbee and sony doesn’t forbid that. i have an unhackable mobo psp, i work in a low-level department in sony, and i don’t agree on how they block things user mode, it’s none of their business what u do with your psp, you paid for it, when that receipt hit your hand, it’s yours, not theirs:>",

The iphone-dev team has officially stated “
all that remains is implementation
“. They’ve developed all the pieces they need to perform a software unlock for the
iPhone 3G
, now it’s just a matter of putting them together in user friendly fashion. They’ve managed to run unsigned code on the baseband,
developed custom AT tools
, and are now showing injection of a background task. They will combine all of these techniques to override the carrier lock baseband code. As usual, they warn against performing any official firmware updates to the phone.

That is why they are reworking the data plans. As for the EVO, Sprint only has about 6 4G network. So you might be stuck paying a 10 premium above whatever data package you get. They each have their strong fronts, as iOS4 (iPhone’s new opperating system) is bringing a lot of new things to the mix. The EVO on the other hand, is already a beast in how fast it is. The update to Android 2.1 called Froyo (2.2) is also on the way. Once that comes out, it will boost Android speeds up to 450%. It will be good to compare them at that point, not when things are stacked in one favor. It comes down to what the consumer wants. I prefer Android, but to each their own.",

Digital Pictures Interactive has put together a great
augmented reality demo
. Unlike many others, it’s entirely Flash based, so there’s no install necessary. Print out the custom symbol and try it out for yourself in your browser.
Augmented reality
refers to any mashup that combines computer generated content with a live video stream. We see great potential for this technology and the large number of consumer
webcams
would certainly help consumer adoption. Video demo embedded below.

Don’t let it, it doesn’t work well that large. That’s what she said.2) it is important that the printed box be against a light background….don’t fold up the page like the guy in the video; leave it.

UPDATE:
New firmware with JTAG and more
We’re always excited to get a new chip or SIM card to interface, but our enthusiasm is often dampened by the prototyping process. Interfacing any chip usually means breadboarding a circuit, writing code, and hauling out the programmer; maybe even a prototyping PCB.
A few years ago we built the first ‘Bus Pirate’, a universal bus interface that talks to most chips from a PC serial terminal. Several standard serial protocols are supported at 3.3-5volts, including
I2C
,
SPI
, and
asynchronous serial
. Additional ‘raw’ 2- and 3- wire libraries can interface almost any proprietary serial protocols. Since this has been such a useful tool for us, we cleaned up the code, documented the design, and released it here with specs, schematic, and source code.
Concept Overview
The Bus Pirate is a serial terminal bridge to multiple IC interface protocols. We type commands into a serial terminal on the computer. The commands go to the Bus Pirate through the PC serial port. The Bus Pirate talks to a microchip in the proper protocol, and returns the results to the PC.
All pins output 3.3volts, but are 5volt tolerant. On-board 3.3volt and 5volt power supplies are available to power the connected chip. Software configurable I2C
pull-up resistors
complete the package.
The serial terminal interface works with any system: PC, Mac, Linux, Palm Pilots, WinCE devices, etc; no crapware required. We considered a USB device, but USB isn’t compatible with the huge number of hand-held devices that have a serial port. We also wanted a 3.3volt device with 5volt tolerant inputs, but most popular through-hole USB microcontollers were 5volt parts (e.g. the
PIC18Fx550
).
The Bus Pirate currently ‘speaks’ three hardware protocols for high-speed interfacing, and has two software protocol libraries for easy bus manipulation. The theory and specification of each protocol is beyond what we can cover here, but check out some of these tutorials:
I2C
A slow 2 wire bus. Wikipedia is a great place to start for
I2C background
.
I2C-Bus.org
,
Robot Electronics
,
Embedded Systems Academy
, and
Embedded.com
have decent I2C tutorials.
SPI
A simple 3 wire bus. Wikipedia has
background
; Embedded.com has a great
tutorial and comparison to I2C
.
Universal Asynchronous Receiver Transmitter (UART or serial)
A clock and timing dependent serial protocol best known for its appearance as the PC serial port protocol. Wikipedia has background on
asynchronous serial protocols
.
Raw 2 wire
This is a generic 2 wire protocol library, similar to I2C but without an ACK bit. I2C and many proprietary 2 wire protocols can be formed using the bus manipulations available in this mode. Use this library to work with non-I2C 2 wire devices, like
smartcards
or
Sensirion SHT11
temperature/humidity sensors.
Raw 3 wire
This is a generic 3 wire protocol library, similar to SPI but without the constraints of a hardware module. Use this library to work with devices that use non-8bit compatible 3-wire protocols, like the
Sparkfun Nokia 6100 LCD knock-off
. Many 3 wire protocols can be formed using the bus manipulations available in this mode.

PIC 24FJ64GA002
We used a
PIC24FJ64GA002
microcontroller in the Bus Pirate; this is the same chip we used in our
mini-server project
. It’s fast enough to do everything we want (16MIPS), and the peripheral pin select feature allows the hardware SPI, UART, and I2C modules to share output pins. Each power pin needs a decoupling capacitor(C12,13), and the MCLR function requires a resistor (R7) between pin 1 and 3.3volts. The PIC has an internal voltage regulator that requires a 10uF tantalum capacitor (C3), though we used a plain electrolytic capacitor without issue. Read about programming and working with this chip in our
PIC24F tutorial
. If you don’t have a PIC debugger, several readers recommend the under-$40 ICD2 clones on eBay.
The PIC runs at 3.3volts, but the digital-only pins are 5volt tolerant for interfacing 5volt logic. Pins 14,15,16,17,18,21, and 22, are digital only, which we determined by looking through the datasheet and eliminating any pins with an analog connection type (table 1-2, pages 11-16). According to the datasheet, I2C pins are also 5volt tolerant. There’s a bunch of conflicting information on the web, but datasheet page 230, parameter DI28, clearly states that the max input for a 24FJ64GA002 I2C pin without analog circuitry is 5.5volts.
Pins 21 and 22 (RB10/11) can pull-up SDA/SCL through resistors R4 and R5.
MAX3223CPP
This chip converts 3.3volt serial output to +/-10volt RS232 signals compatible with a PC serial port. The MAX3223CPP is a 3-5volt version of the MAX202, with extra power saving features. MAX RS232 transceivers require four 0.1uF capacitors for a charge pump (C4,5,7,8), and one decoupling capacitor (C17). We used the same capacitors for everything.
We used a MAX3223CPP, which doesn’t seem to be available anymore.
MAX3223EEPP+
is a pin-compatible newer version, available at Digikey for $7. Ouch! None of the 3223’s power saving features are used, so a cheaper, simpler 3.3volt RS232 transceiver should be substituted if at all possible.
Power supplies
Most chips can be powered from the Bus Pirate’s on-board 3.3volt and 5volt supplies. 5volts is supplied by a common 7805 regulator (VR2) and two decoupling capacitors (C9,10). An LM317 adjustable regulator (VR1) is set to 3.3volts using two resistors (R2,3), and requires two decoupling capacitors (C6,7). The circuit requires a 7-10volt DC supply (J1).

Firmware
The firmware is written in C using the free demonstration version of the
PIC C30 compiler
. Learn all about working with this PIC in our
introduction to the PIC 24F series

main.c – Handles the user terminal interface.
busPirate.c – Abstraction routines that convert syntax to actions on the proper bus.
uartIO.c – IO routines for both hardware UARTs.
m_i2c_1.c – Software I2C routines by [
Michael Pearce
]. We couldn’t get the PIC hardware I2C to work, so we used this helpful library. The software doesn’t take into account the I2C speed setting, and seems to work at about 5KHz.
SPI.c – Routines that drive the hardware SPI module.
raw2wire.c – Software 2-wire interface library.
raw3wire.c – Software 3-wire (SPI) interface library.
User input is held in a 4000 byte buffer until a newline character (enter) is detected. If the first character of the input is a menu option (see below), the menu dialog is shown, otherwise the string is parsed for data to send over the bus (see syntax). The code consists of an embarrassing number of switch statements and spaghetti code.
Terminal interface
Rather than write a junk piece of software to control the device, we gave it a serial command line interface that will work with any ASCII terminal. The bus pirate responds to commands with three digit result codes and a short message. The codes are designed with PC automation in mind. We’ve included a table of result codes in the
project archive
(zip).
Menu options
Menu options are single character commands that don’t involve data transfers. Enter the character, followed by <enter>, to access the menu.
?
– Show a help menu with commands and syntax.
M
– Set the bus mode (SPI, I2C, UART, raw 2 wire, raw 3 wire). Followed immediately by a prompt for speed, polarity, and output state (mode dependent).
Bus speeds: SPI:30, 125, 250, 1000KHz. I2C:100, 400, 1000KHz. UART: 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200bps. Raw modes: 1, 10, 50KHz.
Inverse clock setting sets the idle state opposite of normal (normal SPI:idle low; normal UART:idle high): SPI:idle high; UART:idle low.
Some modes have optional high-z output modes for use with pull-up resistors (Low=ground, High=input).
L –
Toggle bit transmit/receive order: most/least significant bit first.
P
– SDA/SCL pin pull-up resistor toggle (3.3volts). Only valid in I2C and raw 2 wire modes.
O
– Set number output display format. The terminal can display numbers as decimal, hexadecimal, and binary ASCII values. A fourth format sends the raw, unprocessed byte for reading ASCII formatted text.
Syntax
A simple syntax is used to communicate with chips over a bus. Syntax commands have generic functions that generally apply to all bus types.
A/a/@
– Toggle auxiliary pin. Capital “A” sets AUX high, small “a” sets to ground. @ sets aux to input (high impedance mode) and reads the pin value.
[
– Start data write. SPI/raw 3 wire: chip select enabled. I2C/raw 2 wire: start condition. RS232: open UART, discard received bytes.
{
– Start data write with reads. Same as [, except: SPI/raw 3 wire: show the read byte for each write. RS232: display data as it arrives asynchronously.
] or }
– End data write. SPI/raw 3 wire: chip select disabled. I2C/raw 2 wire: stop condition. RS232: close UART.
R/r
– Read byte. SPI/raw 3 wire: send dummy byte, return read. I2C: read byte with ACK. Raw 2 wire: read 8 bits. RS232: check UART for byte and return, or fail if empty. Use 0r1…255 for bulk reads up to 255 bytes.
0b
– Write this binary value. Format is 0b00000000 for a byte, but partial bytes are also fine: 0b1001.
0h or 0x
– Write this HEX value. Format is 0h01 or 0x01. Partial bytes are fine: 0xA. A-F can be lower-case or capital letters.
0-255
– Write this decimal value. Any number not preceded by 0x, 0h, or 0b is interpreted as a decimal value.
, or space
– Value delimiter. Use a coma or space to separate numbers. Any combination is fine, no delimiter is required between non-number values: {0xa6,0, 0 16 5 0b111 0haF}.
Direct bus manipulation commands for raw 2 wire mode and raw 3 wire mode.
^
– Send one clock tick. Use 0^1…255 for multiple clock ticks.
/ and \
– Toggle clock level high (/) and low (\). Includes clock delay (100uS).
-/_
– Toggle data state high (-) and low (_). Includes data setup delay (20uS).
!
– Read one bit with clock.
.
– Read data pin state (no clock).
&
– Delay 1uS. Use 0&1…255 for multiple delays.
Using it
Here are two examples that show the Bus Pirate in action. Terminals should be set to ASCII mode with local echo, we used the Windows serial terminal. The PC-side serial connection is 115200bps, 8N1. The Bus Pirate should respond to any single line feed type (0x0a, 0x0d), or both (Windows style).
.
I2C/SPI – Flash 24LC1025 EEPROM
Microchip’s EEPROMS
are popular permanent-storage memory chips, the
24LC1025
has 128Kbytes of storage with an I2C interface. We can test this chip without bread-boarding a big circuit or writing code.
The picture shows an 24LC1025 connected to the Bus Pirate. The EEPROM works from 2.7 to 5volts, so we used the 3.3volt supply from the Bus Pirate to power the circuit. The on-board SDA/SCL pull-up resistors hold the I2C bus high, and eliminate the need for external resistors. A single 0.1uF capacitor decouples the EEPROM from the power supply.
Setup I2C mode
First, we setup the Bus Pirate for I2C mode and enable the pull-up resistors. Since the Bus Pirate currently uses a software I2C library, the speed setting doesn’t really have an effect.
SPI>m
<–enter m for mode select
1. SPI
2. I2C
3. UART
4. RAW 2 WIRE
5. RAW 3 WIRE
MODE>2
<–enter 2 for I2C
900 MODE SET
Set speed:
1. 100KHz (Standard)
2. 400KHz (Fast Mode)
3. 1MHz (High Speed)
SPEED>1
<–speed doesn’t really do anything…
901 SPEED SET
202 I2C READY, P/p FOR PULLUPS
I2C>P
<–enable the I2C pull-up resistors
205 I2C PULLUP ON
I2C>
Write to EEPROM (I2C)
All I2C operations begin with a start condition { or [, and end with a stop condition } or ]. A write begins by addressing the device (1 byte) and looking for an acknowledgment bit (ACK). If the EEPROM responds, we can send the data location to write (2 bytes) and data payload (n bytes). The Bus Pirate automatically checks for an ACK at the end of each write, and ACKs each read.
The 24LC1025 base address is 1010xxy, where xx is determined by the state of pins 2 and 3, and y is read (1) or write (0) mode. We tied pins 2 and 3 high, making the full write address
1010110
. We’ll start writing to the device at the first data location (
0 0
), and write one to thirteen using a mix of data input formats (
1…13
).
I2C>{
0b10100110
0 0
1 2 3 4 5 6 7 8 9 10 0xb 0xc 13
}
<–I2C command
210 I2C START CONDITION
<–bus start
220 I2C WRITE: 0xA6 GOT ACK: YES
<–address sent and ACK received
220 I2C WRITE: 0x00 GOT ACK: YES
<–write address
220 I2C WRITE: 0x00 GOT ACK: YES
<–write address
220 I2C WRITE: 0x01 GOT ACK: YES
<–data
…
220 I2C WRITE: 0x0D GOT ACK: YES
240 I2C STOP CONDITION
I2C>
Read from EEPROM (I2C)
Reading the 24LC1025 takes two steps. First, a write command with no data sets the address pointer. Second, a read command outputs data starting at the location set in step 1.
The first command is a write command, we use the hexadecimal equivalent of the write address (0b10100110 = 0xa6) to save a bit of typing. The address pointer is set to the location where we wrote our data (0 0).
I2C>{0xa6 0 0}
<–set write pointer command
210 I2C START CONDITION
220 I2C WRITE: 0xA6 GOT ACK: YES
220 I2C WRITE: 0x00 GOT ACK: YES
220 I2C WRITE: 0x00 GOT ACK: YES
240 I2C STOP CONDITION
With the pointer set, we can start reading data. The read address is the device address, with the last bit set to 1 ( 0b10100111 or 0xa7). We used thirteen r commands to read the data, but we could have used the shorthand version: 0r13.
I2C>{0b10100111 rrrrrrrrrrrrr}
<–read command
210 I2C START CONDITION
220 I2C WRITE: 0xA7 GOT ACK: YES
<–chip ACKed the read address
230 I2C READ: 0x01
<–data byte 1
230 I2C READ: 0x02
<–data byte 2
…
230 I2C READ: 0x0D
<–data byte 13
240 I2C STOP CONDITION
I2C>
We know the operation was a success because the output matches the data we wrote earlier.
UART – EM406 SurfIII GPS
The
EM406
is a tiny 5volt GPS module that tracks up to 20 satellites. By default, it outputs NMEA formatted data from a serial port at 4800bps, 8N1. The output format is standard serial, but at 2.8volts it’s incompatible with PC serial ports. The Bus Pirate can interface this GPS without the need for a separate RS232 transceiver or 5volt power supply.
Setup the UART
First, we setup the Bus Pirate UART to receive serial data at 4800bps.
I2C>m
<–setup mode
1. SPI
2. I2C
3. UART

9. 115200
SPEED>4
<–4800bps
901 SPEED SET
302 UART READY

Enable UART and data reads
An important thing to remember about UARTs is that the data arrives asynchronously. Unlike SPI and I2C, where data transfer is controlled by the master, serial data can arrive at the UART at any time. The GPS is a great example of this because it spits out location data continuously, without user intervention.
We developed two read modes to cope with asynchronous data . { echos all incoming data as it arrives. New data will displace and garble data entry, but all input is still accepted normally. [ opens the UART in a send only mode that discards incoming bytes. } or ] closes the UART, regardless of the mode.
UART>{
<–open UART with async reads
310 UART OPEN, } TO CLOSE
330 UART READ: 0x80
<–GPS data
330 UART READ: 0x78
Write to the UART
Type in values to send out the UART. Even if the input is broken up by incoming data, it will be processed on <enter>. We sent
0x40
as an example, but this has no particular meaning to the GPS module.
330 UART READ: 0x80
0x40
<–random byte to write
320 UART WRITE: 0x40
<–byte written
Close the UART
“}” followed by <enter> closes the UART.
330 UART READ: 0x78
303 UART READ: 0x60
}
<–close UART command
330 UART READ: 0xE6
340 UART CLOSED
UART>
Don’t think you can use this GPS data to track us, we don’t actually get satellite reception down here in mom’s basement.
Taking it further
The Bus Pirate is an important development tool in our lab. We keep updating it as we use it, and we’ll release new firmware as we add protocols and features. Expect to see the Bus Pirate in future articles.
These improvements are at the top of our list. Do you have any suggestions?
New protocols: One Wire, CAN, ???
Controls for polarity and other settings
Adjustable instruction delay
Get hardware I2C module working.
Enable protocol speed settings.
Cheaper, easier to get RS232 transceiver

It’s just too messy and infrequent for me to get all the materials required. Plus, the etchant solution is a pain to dispose of — not to mention I live next to a river with a major salmon run. I would be devastated if I accidentally spilled this stuff into the local groundwater.Shoot, Hack-a-Day might consider offering a “collective-buy” PCB service easily enough for projects such as these:Get a critical mass of interested buyers, maybe even payment info too – enough to cover the initial fab costs for a decent sized run. The costs would be covered, and Hack-a-Day would be left with a box of extras.Set up a web-store to sell those extras until they’re gone – and put the $$$ back into the operation of Hack-a-day.Just a thought.

[Jeremiah Grossman] and [Eric Lawrence] will be presenting on clickjacking and browser security
in an online seminar tomorrow
. Clickjacking allows an attacker to transparently place links exactly where a user would be clicking, essentially forcing the user to perform actions without their knowledge. This method of attack has been known for a few years, but researchers have focused their attention on it lately because they feel the threat has been underestimated. Recently, Adobe patched a vulnerability specifically because of this issue. Tune in tomorrow for more info on the attack.

In a bold move, Silicon Graphics has decided to see how
much crap
many cores they can shove in one box.
The Molecule
is 10,000 core rackmount machine designed to leverage low cost consumer CPUs like the Intel Atom. It emphasizes high memory bandwidth and throughput between CPUs. While this sort of space efficiency is interesting it’s certainly going to take some serious cooling to get designs like this off the ground.

We first spotted the Stribe music controller
at Maker Faire
. [Josh Boughey] has since refined the controller’s design so that it can be constructed in a modular fashion and it’s being
sold in kit form by Curious Inventor
. The kit has two columns of 64 LEDs and a
Spectra Symbol SoftPot
for control. You can daisy chain eight modules together using a ribbon cable. It uses SPI control, with a separate wire for the data line (not in the ribbon). An Arduino is used to hook the controller to programs like
Max/MSP
.

Google has been trickling out info about what they’re actually
fixing in the G1 firmware updates
. Before RC29, users were able to bypass the phone lock using safe mode. RC29 also brought WebKit up to date, presumably patching the
bug [Charlie Miller] found
. RC30 takes care of
root console problem
. Unfortunately there are very few details as to what or how particular items were broken. This release method leaves much to be desired; having the official
Android Security Announcements
group be the absolute last place to get security news is asinine.

Reader [Mike] was not too impressed by design in a recent post we did on an
LED menorahs
. Doing what any self respecting hacker would do, he
designed and built a better one
then sent it in to us. He just happened to have an AVR ATtiny13 sitting around, so he used that for the brains. It has single button operation, is powered by 2 AA batteries, and even simulates the candles burning out. His custom PCB turned out quite nicely as well, the power plug connects to the batteries in a way that uses them as a base. Check out his site for detailed plans and source code. Great job [Mike].

Flying Cars A Reality
|

"Transportation Hacks"

[Stillboy] alerted us to a
flying car that runs on biofuel
. Flying cars have been the mainstays of science fiction and technological wish lists for years, but they elude production, as expenses, fuel, and gravity get in the way. [Gilo Cardozo], a
paramotor
manufacturer, managed to overcome those hurdles by thinking simply. He attached a paramotor to his car, which is powered by a Yamaha superbike engine and a gearbox from a snowmobile. His modified
Rage Motorsport
buggy is street legal in the United Kingdom, and in the air, can get up to 80 miles per hour. It will be fully tested in January, when he and his chief pilot and expedition organizer [Neil Laughton] drive and fly the car to Timbuktu.
Other flying cars are also in the works.
DARPA
recently
announced their Personal Air Vehicle Technology project
that will hopefully lead to a military-suitable flying car that can get up to 60 miles per hour on the ground and 150 miles per hour in the air.
Moller International
claims that a
flying Ferrari
is in the works, and could be available for purchase within two years. Are jet packs next?

[Kottke] posted advice for
watching and sharing high quality YouTube videos
. While it’s not HD quality, it’s much, much better than the normal, fuzzy quality you get on most videos. This hack has been available for some time, but it hasn’t been documented very well until now. When you’re logged in, you can just set the default to “Always play higher-quality video when it’s available”. When you’re linking to a video, add &fmt=18 to the YouTube URL. This also works when you’re embedding the link in WordPress. If you’re not in WordPress, then tack &ap=%2526fmt%3D18 onto each URL in the embeddable code. It’s pretty simple, and makes wasting your day at work much more enjoyable.

Take a tour of the Mutex laboratories, where mutants are made and nothing could possibly ever go wrong. [Steve] directed us to these videos of the Halloween set up he did with his son this year. Neighbor kids got to go on an action packed tour where mutants break free from their cages and have to be neutralized with special ray guns. Wow, why didn’t this guy live near us when we were kids? Check out a behind the scenes walk through with some good technical stuff after the break.
[youtube=http://www.youtube.com/watch?v=a3kWN3FdK7Q]
The neutralization guns are made using old IR remotes and detected by
USB-UIRT
receivers. Many of the effects were controlled by
Phidgets
. After all the mayhem, the kids can get a tally of how well they did in the mutant neutralization.

A coworker approached us today with a corrupted SD card. It was out of her digital camera, and when plugged in, it wasn’t recognized. This looked like the perfect opportunity to try out [Christophe Grenier]’s PhotoRec.
PhotoRec
is designed to recover lost files from many different types of storage media. We used it from the command line on OSX, but it works on many different platforms.
It’s a fairly simple program to use. We plugged in the card and launched PhotoRec. We were prompted to select which volume we wanted to recover. We selected “Intel” as the partition table. PhotoRec didn’t find any partitions, so we opted to search the “Whole disk”. We kept the default filetypes. It then asked for filesystem type where we chose “Other” because flash is formatted FAT by default. We then chose a directory for the recovered files and started the process. PhotoRec scans the entire disk looking for known file headers. It uses these to find the lost image data. The 1GB card took approximately 15 minutes to scan and recovered all photos. This is really a great piece of free software, but hopefully you’ll never have to use it.

Company Shutdown Causes 2/3rds Drop In All Spam

The Washington Post is reporting that the shutdown of one hosting company has
caused the total volume of spam to drop by 2/3rds
. The company in question is McColo Corp. Both Hurricane Electric and Global Crossing pulled the plug today
after a damning report revealed
a number of illegal activities happening on McColo’s servers. McColo already had a reputation with the security community. When contacted about abuse, the company would often shift servers to new IP ranges instead of shutting them down. Although not the main source of spam, the company was host to many botnet control servers and
phishing
sites.

Evil Mad Scientist Laboratories have just announced the release of the Meggy Jr RGB, a
fully programmable handheld console
with an 8×8 RGB LED matrix display. Like its big sisters
Peggy
and
Peggy 2.0
, the Meggy Jr is driven by an ATmega168 microcontroller and is made up of a bank of fully addressable LEDs. Unlike its siblings, the device boasts six buttons and the ability to be mounted inside of a custom case (or “handle set”) constructed from plastic or wood, drastically altering the look of the console. Using the popular open-souce
Arduino
environment, users are able to write custom software for the device. While it works great as a game console, of the many possible configurations and suggested uses, we think “disco floor for your
Lego
minifigurines” is the most amusing.

HDDJ: Hard Drive As Rotary Input

[nvillar] wanted a relatively cheap way to make a
rotary input device for audio mixing
. After looking at several options including turn tables and professional audio scrubbers, they decided on the hard drive due to its size, price, and the feel of the disk. The geek factor of using a hard drive as an input device probably didn’t hurt either. They provide schematics and details on how to make it all work. There’s a video after the break of the unit sending signals to a computer. No performances though, sorry.

It had a bit of a problem at low speeds, below a certain angular velocity the spindle motor no longer generates any output, which is unfortunate. As for high speeds, these things are design to spin hard disk platters at 5400 or 7400 RPM so should be accurate!Also, Reezy, what other details do you think we need to supply? Cause I’d be happy to add more info to the instructable.Anyway, it was a fun project, and is easy to do if you have a HDD lying around.",

After I found out that the wheel was constantly pressed into the middle button I disconnected that button. The only thing that the HDDJ project seems to have that this doesn’t is awesomer software potential and ability to “glide” (altho that function could be implemented in software or with a more carefully chosen mouse and a weighted CD).I could not believe how well this little project worked out.

We wouldnt be where we are today if it wasnt for people learning of new ways to do things and at cheaper prices.Second, as I mentioned above, the price.Not everyone has $100 to just spend on a machine that does ONE thing and ONE thing only.If this project was corrected enough, it could be an open source project, which could lead to this nifty device being used for MULTIPLE things.For example, what about using it for volume control as well?All you would need is a cheap (perhaps non-working) hard-drive which would only be a few dollars if not free in some cases. Saving you easily a few hundred dollars.Once again, sorry for reviving and old post, but questions like this in the science community just make me cringe. After all – last time I checked this is a website devoted to purely learning, isnt it?Perhaps people shouldnt be so worried with ‘why’ things happen or ‘why’ people do what they do, and just accept it for what it is.To comment on this project, I think its awesome, keep up the good work fellows.",

Hot on the heels of their
recent rapid-fire mod
, the creative minds at AcidMods have turned out yet another useful hack for for the Wii controller. This time around, they’ve replaced the peripheral’s “A” button with a
clickable trackball

earlier projects
, the team even took the time to add LEDs to the track ball internals. Check out the videos of the mod in action after the break.

Reader [Harald] sent us this sweet
Pringles can macro photography
hack from way back in 2005. Using a Pringles can and a standard Cannon 50mm MKII lens, they have produced some amazing results. The image above is the tip of a ballpoint pen. Not only does he go through the steps to make it, but then goes in depth on how to best set your camera and other good practices for macro photography. Pringles cans aren’t just for holding chips and
making wireless antenna
.
We’ve covered several macro photography rigs before, like
how to do macro photography with your iPhone
, or with a
flip camera
, and even how to build a massive
laser controlled macro photography setup
.

[nmarquardt] has put up an interesting instructable that covers
building RFID tags
. Most of them are constructed using adhesive copper tape on cardstock. The first version just has a cap and a low power LED to prove that the antenna is receiving power. The next iteration uses tilt switches so the tag is only active in certain orientations. The conclusion shows several different variations: different antenna lengths, conductive paint, light activated and more.

I’m the author of the Instructable mentioned here, and so I wanted to reply to your comments.I agree: this is a really, really simple project, and nothing too sophisticated for anyone who has knowledge of RFID. However, it hopefully illustrates how easy it is for non-experts to still explore this usually invisible technology. It is intended as a starting point, that opens directions for more experiments.And to answer the raised question: yes, these tags work with Mifare chips, and yes: the reading distance is in fact very bad (around 2-4 cm). But, considering that we use simple copper tape and a simple antenna layout, it is still surprising that it works (at least for me). The Sonmicro reader receives the unique ID of the chip, and I can write data packages to it. I did many more experiments with RFID, and I hope I find the time to share more of them with everyone who is interested in it. So far, this includes a collection of over 25 various tags, many different sensors, active tags, custom readers, and PCB tags (which are much, much smaller).",

[Jay Freeman] has a rather exhaustive tutorial on how to
set up a Debian environment on your T-Mobile G1
. The first major issue with this is that
getting root level access through telnetd
is being patched. It certainly is a security issue that needs to be fixed, but a user shouldn’t have to root their own phone to begin with. While the G1 comes with some
Linux tools
, they’re limited. [Jay]’s goal was to create a familiar Debian environment on the phone. It takes a few tricks, but if you’re familiar with the command line, you shouldn’t have any problems. Debian already has ARM EABI support, so creating a working image isn’t a problem. The image file is stored on the SD card and mounted using the loopback device. The G1’s kernel has module support turned on, so [Jay] created an ext2 and unionfs kernel modules. [Benno Leslie]’s
Android version of busybox
is used to perform the actual mounting. Once mounted, you just need to
chroot
into the environment to start playing with native Linux apps. [Jay] takes this a step further by using unionfs to make the Android and Debian environments share the same root. This is really a great how-to and it’s nice to know that modules can be added to the kernel.

[Dean Kamen]’s company, the people behind the Segway, have created a
hybrid car that uses a Stirling engine
instead of a standard internal combustion engine.
Stirling engines
are closed cycle, meaning heat is applied to the outside of the cylinder walls. They are generally more efficient than standard car engines, but haven’t been used much outside of industrial applications. We suspect that the drivetrain arrangement is similar to the
Chevy Volt
where the engine is used to charge batteries which are in turn driving an electric motor. This is different from modern hybrids that can have either electric motor or gas engine driving the wheels. The article is unfortunately full of classic [Kamen] hyperbole and minimal detail. He calls the Stirling engine “an insurance policy” for the electric car since it can recharge the battery. That’s right, folks. If you run out of juice, you can put gas in the car. I doubt many Prius owners will fall out of their chair over that. Being a Stirling engine, we’d be more impressed if you could charge the thing by rubbing warm toast on it.

But if you’re running a serial hybrid like this one, you don’t care if the combustion engine takes a minute or even a few minutes to get up to speed, and you aren’t exactly trying to make it airborn, so the mass matters less if you get efficiency to compensate. I keep meaning to try to get an estimate on the size of a steam engine capable of producing the average power consumption of a car…",

Attempting to put our past behind us as quickly as possible, TIME has released what they feel are the
best inventions of 2008
. While there’s some pretty wishy-washy lab-only stuff on the list, we’re glad to see a lot of cool hardware made the cut. Some of our favorites are: The
Tesla roadster
proving electric cars can be fun. IBM
breaking the petaflop barrier
with LANL’s Roadrunner. The
Large Hadron Collider
for getting everyone scared about physics all over again. Have a look at the list for many other tech highlights from this year.

[Martin Beck] and [Erik Tews] have just released a paper covering an improved attack against WEP and a
brand new attack against WPA
(PDF). For the WEP half, they offer a nice overview of attacks up to this point and the optimizations they made to reduce the number of packets needed to approximately 25K. The only serious threat to WPA so far has been the
coWPAtty
dictionary attack. This new attack lets you decrypt the last 12 bytes of a WPA packet’s plaintext and then generate arbitrary packets to send to the client. While it doesn’t recover the WPA key, the attacker is still able to send packets directly to the machine they’re attacking and could potentially read back the response via an outbound connection to the internet.

[John Peterson] created this postal scale device for a Renesas design contest. The Weasure not only calculates the
package’s total weight but the dimensions as well
. He built it using a SKP16C62P evaluation board that had an LCD, pushbuttons, and indicator LEDs. The original DigiWeigh parcel scale was modified to provide PWM output and tare control. He embedded photoresistors every inch along each axis. They were angle slightly upward and the surroundings were painted black to minimize reflection. The Weasure outputs everything via a serial connection so it can be used with shipping software to generate postage.

The G1 ‘
execute every command you type
‘ bug naturally spawned ‘rm -rf /’ jokes.
rm
is the Linux command for deleting files. The -r and -f flags will cause it to remove files recursively and ignore confirmation. Executed as root it will annihilate the entire filesystem. Won’t it? [Jon Hohle] decided to
test exactly how destructive the command was
to *nix systems. How functional would the system be afterwards? He tested it side by side with the Windows equivalent, both ‘format c:’ and ‘del /F /S /Q’. He wanted to see what protections were available and what would be left working.
Linux
ended up completely broken while Windows, thanks to file locking, actually shutdown cleanly… and never came back. Some OSes,
like Solaris
, refuse to run the command ‘rm -rf /’ to prevent accidents.

We’re barely past Halloween and people are already working on their next LED based holiday decorations. For Hanukkah,
Gizmodo
pointed out the
PCB menorah
pictured above. It uses a set of DIP switches to control which LEDs are lit. A couple years ago, Evil Mad Scientist Laboratories put together a tutorial for
building a more minimal LED menorah
. Each of the nine LEDs are soldered directly to the legs of an ATtiny2313 microcontroller. Every time you power up the device an additional LED is lit. [Ori] liked the project and decided to take a
slightly different approach
. He used an LM3914 DIP18 LED bar driver. A potentiometer controls how many of the LEDs are illuminated.

This is one of the more bizarre bugs we’ve ever heard. The
T-Mobile G1
has an open root shell that
interprets everything you type as a command
. It was discovered when a user just happened to type the word ‘reboot’ in a conversation and the phone immediately rebooted. A patch has already been rolled out to fix this issue. It also buttons up the earlier
telnetd SUID problem
.

Tinker.it has published plans for building a software synthesizer using an
Arduino
. The
Auduino
uses granular synthesis to create a truly unique sound. The grain is constructed from two triangle waves. Each one has adjustable frequency, decay rate, and the repetition rate can be changed too. The Arduino just needs five potentiometers attached to the analog inputs and an audio jack on the digital out. You don’t have to use pots; you can use anything that varies the analog input between 0 and 5 volts. A video of the device is embedded after the jump.

Google just
announced the release of SketchUp 7
. SketchUp is a 3D modeling program with a fairly robust free version. They’ve added quite a few features and the one that caught our eye in particular was dynamic components. Dynamic components have behavior specific to the object. The example in the video above shows a staircase changing the number of steps as its height is increased instead of distorting the overall staircase shape. The new version also allows for interaction, so model properties change based on user actions.
Google has always encouraged sharing of objects created in SketchUp.
Thingiverse
launched today with a similar emphasis. The site is built to encourage the exchange of plans for physical objects. It supports many different file types from plain images, AutoCAD dxfs to Eagle schematics. Many of the designs already posted are made to be cut out by a laser cutter or built by a 3D printer.

[Cameron Adams] recently appeared on a panel about JavaScript libraries. He represented the hard working coder that still wrote everything from scratch. He wanted to make something mindblowing for the audience. He ended up creating the JS-909
drum machine entirely in javascript
without relying on libraries or flash. While he makes no claims of compatibility, it certainly is a nice bit of kit.

Adding LEDs makes everything better. Watch this video as a regular old
DS
gets turned into one of the most awesome things on the planet. A ton of LEDs were added, some to the body, some to an extra cartridge, some behind buttons. Parts are wired into the speakers, so you get nice effects to your music. We’ll bet the battery life suffers, but who cares. This thing is worth it. This was originally taken from
Nico Nico Douga
, which overlays the comments on the video.

Honeycomb Tire Won’t Go Flat

A
new breed of tire
has been developed that won’t go flat, even if it gets bombed. Resilient Technologies L.L.C. has started making these decidedly cool looking tires for the military. The honeycomb of stiff but flexible plastic acts as a shock absorber just as an air filled tire would. Unlike a normal tire, it won’t pop. You would have to completely destroy the tire to stop these. The article mentions that this isn’t the first of its kind.
Michelin has made the “tweel”
for industrial uses, but you may recall the video of the Audi driving around a course using them. If not, check it out after the break.

We already know that the current generation of run-flat tires are horrible performers in both a comfort and performance arena.

Is it not precisely because of their larger contact area?The primary problem with off-roading is that you *do not have a fixed surface.* That means that everything you learned in physics 101 about coefficients of kinetic friction, etc., goes straight out the window.Frequently, when you apply too much lateral force and not enough normal force, you end up propelling the surface instead of the vehicle. Furthermore, because the surface is deformable, you often rely treads on digging in and creating an interlocking substrate with the surface, rather than simple friction between the surface of the ground and the surface of the tire.Your deduction is only valid for smooth, fixed surfaces. (and even then the event of significant heat transfer during braking can obliterate the expected coefficient of friction if there is not enough contact distribution)",

When we created our
backpack strap WiFi detector
for Engadget, we embedded soft switches to control the device. They used two sheets of aluminum foil separated by a layer of foam with holes punched in it. [Plusea] has taken a similar approach but has
replaced the aluminum foil with conductive fabric
. The end result is a set of three soft buttons that can be easily washed. Have a look at the video of it in action below. Check out the followup project that uses the buttons to
replace a scroll wheel
.

[Deviant Ollam], lockpicker and
beverage cooling contest
host, was recently in Vienna, presumably for
DeepSec
. While there, he stopped by the
Metalab
hackerspace and checked out their
RepRap
rapid prototyping machine. You can see video of his visit above. He had them construct a custom fitted cover for the flash of his point and shoot camera. That’s what we love about rapid prototyping. Many of the projects we cover here solve a particular problem, but would never be considered commercially viable enough to put into production. With the availability of rapid prototyping increasing, hackers can start moving toward producing even more complex objects specific to their needs with a finish closer to commercial products.

Liquid Tree
is decorative, functional, and green. It’s a liquid feedback display created by [Jia Yi Lin] that is designed to tell you exactly how much water you’re wasting in the shower. Behind the pretty tubes is some interesting hardware. [Lin] used an
Arduino
board, and based her code off the
Unipolar Stepper example
. She’s posted her own
code
and
wiring
for the project. When hot water is turned on, the motors decrease the amount of liquid in the tubes. This causes the pattern to slowly disappear, indicating water consumed.

"content": "From what I can tell, the device have two rheostats which controls their respective stepper motor through a arduino. The tubes with coloured liquids are sealed and only partially filled, with have plenty of slack behind the front panel. The stepper motor is connected to the slack part of the tube via a string (can hardly see it in the photo) and as it turns, it lowers the tube causing the liquid in the front to flow to the slack part behind.It doesn’t appear to be connected to the water system at all. Presumably, the user is suppose to gauge his water usage rate and set the rheostat accordingly. Looks nice, but technically not all that impressive.",

Only issue can be the energy you used to clean it originally, and since most water is groundwater that’s not too much of an issue, and if you have to use power for the pumps, well you can use green power created with renewable resources.In short all the water saving talk is pure BS unless you live in a third world desert region, and I wish people would stop that nonsense already to be honest.",

Water rights, conservation, scarcity and drought has been an issue in Colorado for a long time. A farmer even once dried up the Colorado River! The water you use doesn’t all make it’s way neatly back into nature to replenish itself. Some communities are heavily dependent on rain or snow pack to replenish aquifers and reservoirs. You can indeed waste water, or at least use it faster than it can be replenished. Denver has had water restrictions on and off for years, so it’s definitely a serious issue for some.Perhaps the device isn’t relevant to you or your community, but it is to others. Either way the project is neat.",

As some posters have mentioned it is not necessarily a problem in your own backyard but rather those further down the river. Rain does not automatically mean more water to use, it is incredibly naive to be so shortsighted and say water conservation is a crock of shit. Groundwater aquifers take a long time to recharge and excessive draw down can permanently damage the water table in some areas.",
