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
?

] | 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. | 10 | 10 | [

] | 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.

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. | 7 | 7 | [

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.

sweet Xbox 360 arcade controller
project(

). 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

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

shows three outputs, but there’s room for adding two more. A useful bit of kit for only a two hour job. | 2 | 2 | [

how to solar power your gear

open source power line communication
. A
TOR-based VPN
, an
open source BIOS
,
rapid prototyping
,
holographic techniques
, and
running your own GSM network

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

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. | 17 | 16 | [

] | 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]. | 27 | 27 | [

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. | 5 | 5 | [

] | 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

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

<–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>
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
(PDF).

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.

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.

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>
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. | 27 | 27 | [

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.

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.

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=4
…

<–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

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

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.

Cythbot

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

] | 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.

favorite Wiimote projects

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.

[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.

] | 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. | 70 | 50 | [

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.

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.

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

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.

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.

] | 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
. Download the
project archive
(ZIP).
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.

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

220 I2C WRITE: 0x00 GOT ACK: YES

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

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

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.

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.

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. | 17 | 17 | [

Peggy

, 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

] | 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
, allowing the player to quickly navigate menus without readjusting their hold on the Wiimote. With a flair akin to that displayed in their
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.

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

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.

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.

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.

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.

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
