Parts: Ferrite Beads

[ "Misc Hacks", "Parts" ]
[ "choosing parts", "electronics", "ferrite beads", "impedance", "parts" ]
Ferrite beads (L1 in the photo) filter high frequency power supply noise by converting it into a tiny amount of heat. Power supply noise can cause various problems for many parts, especially in analog audio and display circuits. Ferrite beads are simple, but choosing one can be confusing because they’re not commonly used by hobbyists. Most designs will still work if you omit the ferrite bead(s), but beads are so cheap there’s no reason to sacrifice the added reliability they provide. We describe how we pick ferrite beads for our projects after the break. A ferrite bead is rated for current, impedance, and resistance; see this Mouser listing for an example. Unless a datasheet or circuit requests specific bead characteristics, we choose a bead rated for sufficient current, and ignore the impedance and resistance values. If the bead is for a power supply, we determine the maximum possible current the circuit will use and find a bead rated for double that amount. Last week we calculated the the Bus Pirate’s worst-case current consumption as 525ma, so we looked at beads rated for at least 1000ma. We used this one , which is rated for 1500ma and costs 10 cents. Sometimes a ferrite bead is used to filter the power supply for one specific part of a circuit. We used a dedicated bead to filter the LCD bias voltage on the DIY digital picture frame , and with the ENC28J60’s ethernet transceiver on the web server on a business card . These parts only consume a few milliamps, so we used a smaller 200ma ferrite bead ($0.11). Like this post? Check out the parts posts you may have missed. Want to request a part post?

I was not aware of this and was about to jump upon the claim made in the article about converting high frequency noise to heat.Inductors can also be used to cancel noise but (ideally) do not create any heat. They store energy in the magnetic field during half of an AC cycle and give it back on the other half of the cycle. In fact they function the same as capacitors but with “voltage” and “current” switched and with “magnetic field” instead of “electric field”. So they do not dissipate energy as heat just as capacitors don’t dissipate any energy. In fact you can plug a inductor or capacitor into the wall socket (but don’t do it unless you are sure the part is rated for this) and it will draw no power even though you can measure a current flowing through it. Your power company will not charge you any money for this because the power flows into the load for half of the cycle and back out to the power company for the other half of the cycle. There will be small resistive losses though due to the fact that the wires are not perfect conductors.I never knew that ferrite beads operated any differently than inductors. Wikipedia has some good starting information. It seems that ferrites are better for high frequencies both because of their resistance and because of the lack of parasitic capacitance. From a quick look it seems that with the right material they can filter down to 1 MHz. Too bad (for me) that they can’t filter audio-frequency noise out of the power supply.", "parent_id": null, "depth": 1, "replies": [] }, { "comment_id": "80621", "author": "Rlyeh_drifter", "timestamp": "2009-07-07T04:58:17", "content": "The physics behind ferrite beads, inductors and all parts with magnetic flux are the same.“While ferrite beads do have some inductance, they are commonly used as frequency-dependent resistors”please bear in mind that the rising resistance of the ferrite bead is exactly because it has inductance. The (complex) resistance of any inductor is Z=1/(j*w*L) with w=2*pi*f. So any inductor will show a lower resistance to DC than to HF-Noise or Signals.I think/hope you (yaff) meant the following:any conductor has a (parasitic) inductance, but ferrite beads are special inductors, because they operate up to high frequencies where the complex resistance is dominated not by plain resistance but by inductance and parasitic capacity so it is easier just to stat the complex resistance.Its in the material, you cannot use a hunk of metal to make a transformer at 1000kHz, Ferrite takes you to much higher Frequencies because the conductivity of ferrite is much lower resulting in no eddy currents.

There’s a “Placebo Effect” Aura -like the niche marketed magic cables etc where the perception of what ferrites do has become an unquestioned reality. Here lies a path well worth education’s best efforts. As properly applied ferrite devices literally make some designs workable or unworkable. Ferrites have some performance factors unmatched pound for pound compared to any other method of solving a parameter need. That’s why an iron core transformer power supply weighs tens of pounds to the tens of ounces for switch mode ones for one example.Try constructing for another good example- a “Joule Thief” with no ferrite materials. Then, as a design proof of concept, make a workable joule thief from supressor grade ferrite beads. It’s an object lesson in non-trivial maths to do it by the book.

Tennis Practice For Hackers
Caleb Kraft
[ "Nintendo Wii Hacks" ]
[ "tennis", "wiimote" ]
Here’s an interesting WiiMote based project. [Mans] is a tennis fan, though a bit out of practice. With the tennis season coming to a rather climactic end, he got excited and wanted to brush up on his skills. He found the toss part of his serve to be very sloppy. Being a hacker, the first thing he thought was that there must be some way of tracking and graphing his toss so that he could improve it in an intelligent and controlled manner. The WiiMote seemed a perfect fit for this. Only a small modification was necessary, an external button wired to the internal “-” button. This switch is active while he’s holding the ball, and inactive when the ball is released. In this manner, he can track and chart his toss to find out exactly where he needs improvement.  He uses [Johnny Chung Lee]’s code, with a small but unspecified modification to write the accelerometer data to a text file. As he points out, this could be very usefull for any repetitive movement. Whith accelerometers getting cheaper and cheaper, there’s nothing stopping you from using multiple ones either. Imagine a golf rig to analyze your swing, Maybe a boxing rig that measured your hip twist and arm extension, or possibly a yoyo glove to tell you if your flick needs some help. Great job [Mans].

Automated Dorm Room Door
Caleb Kraft
[ "home hacks", "iphone hacks" ]
[ "app", "door", "dorm", "lock" ]
[youtube=http://www.youtube.com/watch?v=46s7nE72nvI] [Chris] wrote in to tell us about this project he did while living in the dorms. He built a system to automate his dorm room door . It handles unlocking and opening/closing the door via iPhone, secret knock, and even the key.  The lock/knob portion is handled by a servo while the opening/closing action is hydraulic. After living with it for a year, he says that it never gets old, but there were a few bugs. Apparently it would randomly open in the middle of the night sometimes. If you’re interested in doing something like this, but not damaging the door, maybe you should check out the RFID dorm door lock project .

Tiniest Bot, Sort Of. CNC Controlled
Caleb Kraft
[ "cnc hacks", "Robots Hacks" ]
[ "cnc", "magnetic", "micro", "small", "tiny" ]
Here’s an interesting concept, the bot pictured above has no internal control mechanisms .  His claims to have built the smallest bot are dubious, considering it requires a much larger control platform to function, so lets just set that aside and look at how it works. The bot itself is basically a hollow box with a hinged manipulator mounted on it. He has then built a modified CNC type structure with various magnets below a platform. The magnets can move the bot and control the manipulator (assuming the bot isn’t trying to pick up anything magnetic). He talks about this being a possible control scheme for smaller bots, though we think he would have to make some major advancements to his magnetic controls for accuracy’s sake. As for his claims of being the smallest, well, we’re sure we’ve seem similarly sized bots, even hexapods ,  that were completely self contained.

WTF-O-meter
Caleb Kraft
[ "Arduino Hacks" ]
[ "arduino", "wtf" ]
Here’s something every office probably needs. Ours does at least. It’s a WTF counter . When the office gets just a little too weird, someone hits the button and it gets logged. It’s probably pretty easy to judge the day by the WTF chart. The button is connected to an Arduino that updates the status on a local web server. We can imagine a nice bar graph of WTFs per day, or possibly a pie chart with normal time vs WTF time. Unfortunately, imagining is all we’re going to do. They didn’t include any examples of the visualizations. Can you imagine saying something to a co worker just for them to promptly march over and slap the WTF button? Maybe we don’t need one.

SparkFun Open-sources Latest Kits

[ "adafruit", "AVR", "clockit", "electronics", "open source", "osh", "sparkfun" ]
SparkFun has started to release some of their kits as open-source hardware . Projects such as ClockIt , a simple alarm clock, have their schematics, board designs, and source code released under the CC-by-sa license. Although most of their widgets and projects already had example code and schematics available, they are now using an open-source license. They are joining adafruit and EMSL and others in pushing OSH, but it is interesting to see an established company turn to this. Normally, startups do this to encourage early adoption. [via adafruit ]

Dubbed Self-Portrait Machine , it comments on how much in society is created by machines and we are dependent on them. Unlike previous drawing robots , the user is part of the sketching process.

Crack WEP Using BackTrack

[ "backtrack", "lifehacker", "linux", "security", "wep", "wep cracking", "wifi", "wireless" ]
Lifehacker wrote a guide for cracking a WiFi network’s WEP password using BackTrack . BackTrack is a Linux live CD used for security testing and comes with the tools needed to break WEP. Not just any wireless card will work for this; you need one that supports packet injection . The crack works by collecting legitimate packets then replaying them several times in order to generate data. They point out that this method can be hit-or-miss, especially if there are few other users on the network, as the crack requires authenticated packets. We covered cracking WEP before , but using BackTrack should smooth out compatibility issues.

Scratchbot: Whiskers To The Rescue
Caleb Kraft
[ "Robots Hacks" ]
[ "rat", "rescue", "whisker" ]
[youtube=http://www.youtube.com/watch?v=GTekO_RQCzE] Scratchbot is designed as a rescue bot , going places where there is low visibility. It’s defining feature is the fact that it uses “whiskers” to feel for things. We feel like this is a little gimmicky. If it is a low visibility situation, wouldn’t IR or audio, possibly sonar be a more effective? How would it differentiate between different physical obstacles? Are the whiskers really new? Aren’t they really just bump sensors? Maybe they have something a little more complicated going on. There was another recent bot that utilized whiskers and compared different tactile profiles to determine what it was touching.

How-to: Bus Pirate Probe Cable
Ian
[ "Featured", "how-to", "Misc Hacks", "Tool Hacks" ]
[ "bus pirate", "bus pirate cable", "cable", "probe", "test hooks", "test lead", "test probes", "tweezer" ]
Update, Saturday July 4th, 2009: All preorders are closed. A probe cable makes it easy to connect the Bus Pirate to a circuit and get hacking. Good test clips make quick connections on cramped PCBs without causing short circuits. We made two cables for the Bus Pirate v2 , keep reading for an overview of our designs and list of part suppliers. Friday, July 3, 2009 is the last day to pre-order a Bus Pirate. There’s only two days left to get your own Bus Pirate , fully assembled and shipped worldwide, for only $30. Overview We use these cables to connect the Bus Pirate’s I/O pins to a microchip or test circuit. A cable consists of a 2×5 connector, a cable, and some kind of attachable probe like an alligator clip or test hook. The gray cable (top) is a ‘junk box’ cable, we recycled it from scrap parts and old computer hardware. The ‘expensive’ cable (bottom) uses high quality and special-order parts. 2x5pin female connector The Bus Pirate’s I/O header is two rows of five 0.1″ spaced pins. We used a 2×5 arrangement because 2x5pin female ribbon cable connectors are common and cheap. We decided against a single row of 10 pins because the connector is an expensive specialty item. The pin names are shown above, and are silk-screened on the bottom of the PCB. See the Bus Pirate page for detailed descriptions of each pin function. The junk box cable uses a 2x5pin female connector from an old PC ISA card. The expensive cable uses a black connector with a reinforced cable holder. Mouser has gray connectors ($0.69) and black connectors ($1.15). Ribbon cable connectors have internal pins that pierce the cable when the top part is pressed onto the bottom part. Ribbon cable Standard 2x5pin female connectors attach to 0.05″ 10-strand ribbon cable. The wire thickness is usually 22, 24, or 26 AWG. We think 12inches (30cm) is a useful length that doesn’t get in the way. Grey ribbon cable is pretty common. We salvaged a piece from an old computer connector, you might get lucky and find one with a 2×5 connector already attached. A color coded cable makes it easy to identify each connection. DigiKey has 5 foot sections ($3.03), Mouser has it by the foot ( $1.16 , $1.19 ). Ribbon cable is cheap and readily available, but it tends to tangle and kink. A really nice probe could use a ribbon cable stub attached to thicker test leads. Test clips Test clips are the most important part of the cable. They have to be easy to position, and maintain contact with the circuit. Alligator clips work, but there’s a lot of exposed metal that can create short circuits. Professional test clips have a grabber that retracts into the probe leaving less metal exposed. Alligator clips The junk box cable has alligator clip probes, we pulled them off test leads like these (40 leads for $12). You could also use loose red and black clips (20 for $2.30). Remember to put the rubber housing on the cable before soldering the wire to the alligator clip, it won’t go on later. In the photos you can see that some of our covers are cut to fit over the front of the clip because we forgot. Round test hooks This is the classic, round-bodied test hook. These are great for grabbing onto 0.1″ pin headers, wires, and the leads of through-hole components. The hooks are usually too big to use with surface mount components, and the round body makes it hard to fit more than a few in a small space. Test hooks are easy to position. Squeeze the probe to extend a single metal hook, grab something, then release. The hook retracts into the body of the probe, securing it in place and preventing short circuits. Most hooks come apart by pulling the top away from the body. Put the test lead through the hole in the cap and solder it to the metal tab. Push the halves together when the joint is cool. DigiKey ($17.26) and Fry’s ($14.95) have multi-colored hooks in sets of 10. Deal Extreme has dirt-cheap 10 packs of yellow ($2.30)  and black ($2.33) hooks, but the reviews say the quality matches the price so buy extra (via [ haku ]). Flat test tweezers Tweezer-probes are great for clipping onto the legs of through-hole, surface mount, and many smaller chips. They usually have a flat body so they fit better in tight spaces than round hook probes. This type of probe has tiny tweezers instead of a hook. Accidental short circuits are rare because there’s so little exposed metal when the tweezers retract. Most tweezer-probes pull apart and have a metal solder tab inside. Run a cable strand through the hole in the cap, solder it to the metal tab, and then press the halves back together. Tweezer quality varies dramatically among brands, we’ve used no-name probes that bend easily or don’t grip well. The X- series micro-hooks from E-Z-Hook are the Cadillac of tweezer-probes, we first used the XKM version that comes with the Saleae Logic . They’re intended to fit specialty test leads, but it’s easy to solder a wire to them instead. About $2 each, available directly from the E-Z-Hook website . Conclusion We highly recommend a cable with hook or tweezer-probes for secure connections without causing shorts. The right probe depends on the parts you use. Round test hooks work best with through-hole parts and wires. Flat test tweezers attach well to small, surface mount chips. Please share any additional part sources in the comments. We did our best to provide a variety of sources, but there’s going to be some great places we’ve missed. Friday, July 3, 2009 is the last day to pre-order a Bus Pirate. There’s only two days left to get your own Bus Pirate , fully assembled and shipped worldwide, for only $30.

Battery Desulfator

[ "12v", "ATmega169", "automotive battery", "battery", "battery desulfator", "desulfator", "mikey sklar", "youtube" ]
Hack a Day favorite [Mikey Sklar] is back with a new project. Mini-D is a battery desulfator . If a 12V lead-acid battery sits with a voltage below 12.3V, sulfur crystals will begin to form on the lead plates. This crystal growth increases the internal resistance and eventually makes the battery unusable. A battery desulfator sends high frequency pulses through the battery to create a resonance that will break up the crystals. On a 60lb automotive battery, it will take approximately three weeks to completely desulfate. You can find schematics plus a dozen lines of code for the ATmega169 on his site. Embedded below is a video where he explains the device and other techniques like load testing. [youtube http://www.youtube.com/watch?v=5MJZMkQawB8%5D

Capacitive Discharge Spot Welder Update

[ "capacitive dischage welding", "capacitive discharge", "podecoet", "spot welder", "update", "welder" ]
It seems one of our commenters took great umbrage with [PodeCoet] not documenting his capacitive discharge cutting properly. [PodeCoet] had been waiting till he got the full spot welder working before publishing, but he’s expedited the work after all our whining. Check out his full writeup of the device in its current state . It uses a 1Farad audio cap for storage. A dsPIC monitors all of the voltage sources and regulates charging. A nice touch is the tactile switch on the electrode.

It’s an interesting idea for sculpting.I’m playing with an XYZ gantry to do something similar to this (it’s a CNC mill, basically) and the cool thing about EDM is that you can cut very fine shapes and drill holes that you can’t really do easily with end mills.A lot of people use lasers, but lasers have their own issues – EDM can cut reflective materials and has some advantage. You can blow inert gases over the working discharge with good results – you get less burning of the material.There isn’t a big call for it, but my problem is to make a bunch of parts out of thin reflective metal stock. For me, an EDM flatbed plotter is the perfect solution, mostly because I can’t economically use big laser cutters on such tiny one-off items (usually under 2″ in diameter).PS – despise me if you will, but I would have reacted in the same way to such a comment, which is why I worded it as I did.

Home Power Monitoring

[ "arduino", "dns", "ethernet shield", "power monitor", "webserver", "wrt54g" ]
Reader [john] finished up his home power monitor over the holiday weekend. It uses a pair of current transducers clamped onto the mains. These output 0-3V and are read by the Arduino’s ADC. The Arduino averages samples over a 20 second period, calculates power used, and uploads it using an Ethernet Shield. The shield can’t do DNS lookups, so he uses a WRT54G to negotiate with the remote webserver. He admits that the system could be more accurate; it can’t detect small loads like wall warts. He also says that money could be saved by talking serial to the router instead of over ethernet. Here are the current usage charts . You can find many power monitor projects like this in out Home Hacks category .

The TV-B-Gone has proven to be a dangerous and versatile gadget. At Interactive Matter, they created an even smaller version with more sneaking potential. Called the µTVBG, it packs an entire TV-B-Gone in a 1.4 x 2.5 cm footprint and even has room for a programming header. He found some high-powered surface-mount IR LEDs that would match the original TV-B-Gone’s power. To drive the board, they used a CR1220 button battery on the bottom of the board. The whole thing is smaller than your thumb and should be easier to hide next time you wreak havoc.

Capacitive Discharge Cutting
Steve Watkins
[ "home hacks", "Misc Hacks", "Tool Hacks" ]
[ "capacitive discharge", "controller", "diy", "electronics", "microcontroller", "youtube" ]
Capacitive discharge cutting provides more control than linear transformer versions. A very large capacitor is charged to a precise voltage and then discharged through the material to produce a controlled cut. The same device can also be used for spot and tab welding. A video of copper roof flashing being cut is embedded below. An example of a linear transformer can be found in our our How-to: build your own spot welder .

This antenna tuner is controlled remotely using geared motors and legos. The tuner needed to be closer to the antenna for performance reasons. This created a problem; most of the radio gear is inside while the tuner is outside. The gear motors and Legos combine to form a closed loop servo, operating two air core caps and an inductor switch. A control box placed near the radio is hard wired to the modded tuner outside. We would like to see something like this under gesture control using the Wii MotionPlus + Arduino .

Last Day To Preorder Your Bus Pirate

[ "News" ]
[ "bus pirate", "bus pirate order updates", "news", "preorder" ]
Update, Saturday July 4th, 2009: All preorders are closed. Today is the last day to pre-order a Bus Pirate. Get your own Bus Pirate , fully assembled and shipped worldwide, for only $30. We don’t plan to make more soon, this could be your last chance. A special shout out to our partner, Seeed Studio , who handled the rush of orders like pros. The first pre-order is already being manufactured, and will ship as soon as possible. Seeed still has a few V2a PCBs if you’d like to roll your own Bus Pirate. You’ve made this pre-order a huge success, and we’d like to make more projects available in the future. Were you just interested in the Bus Pirate? Should we arrange pre-orders of future Hack a Day hardware? Are there any past projects that we should revisit? Thanks for the artwork [ Aaron ], licensed under Creative Commons Attribution 3.0.

[youtube=http://www.youtube.com/watch?v=QReb1hLfdbE] Stairs are one of the most commonly faced mobility challenges for a robot. This robot’s design eliminates the need for a complex drive train or computer, and instead uses a clever mechanical design to climb stairs. Version three of the robot uses five servos modified for continuous rotation, a Picaxe28, sharp IR sensors , and bump sensors. [via BotJunkie ]

They learned that lots of people are willing to contribute. Hundreds have signed up on the site to participate. Theyve also learned that laziness is the key road block on this project. The boxes that have stalled generally sitcollecting dust, simply because someone hasn’t bothered to ship it off. If you’re curious what kinds of stuff ends up in one of these, check our initial post . There aren’t any guarantees though, it all depends on what people toss in.

Poor Man’s Thermographic Camera

[ "camera", "electronics", "Imaging", "infrared", "ir", "Thermal", "Thermographic", "thermographic camera" ]
Using an IR thermometer, there are two ways to go about building a thermographic camera . The first uses a pan and tilt head. Scan lines are emulated, as a computer controls panning from left to right, taking a temperature sample from each step. Vertical resolution is accomplished by tilting. Another method uses a web cam attached to the thermometer. The thermometer’s laser pointer is captured with temperature annotations, as the computer records the field of view. We think the best outcome can be found with a combination of both methods. The video embedded below demonstrates the results. This would be a good addition to the Autonomous paintball sentry .

Firework Ignitors And Controllers Roundup

[ "Cellphone Hacks", "Roundup" ]
[ "4th of july", "arduino", "cellphone", "controller", "diode", "diy", "electronics", "fireworks", "ignitors", "match", "microcontroller", "wireless" ]
With the 4th of July around the corner, we thought it would be a good idea to give a controller wrap up and show you how to make some ignitors. Last year we covered a microcontroller based fireworks launcher . If you like the idea of a controller but don’t want to run all the wire, we have the wireless fireworks controller . Adding a little twist to the wireless scene are cell phone triggered fireworks . Maybe controllers are not your cup of tea, you could try to microwave your fireworks . After the break we show you how to make ignitors from a diode and a match. Using a 1N914 diode, match, and 4 ohm ballast you can make your own ignitors. Using the leads for support, the diode is attached to the match. A current is passed through the device to cause rapid heating. The match head and component must touch one another, in order to ignite. In the video embedded below we show you exactly how. [youtube=http://www.youtube.com/watch?v=JwyIKEndOxg]

But it takes about 8 seconds depending on the lead resistance. The diode will burn in about 3 seconds with the same leads. There is another thing to keep in mind and that is if you are using a length of wire the series resistance will impeded the operation of these crudes devices. I tested a 500′ spool of copper 18/2. The total series resistance was 7.5 ohm. Neither the diode nor the resistor will work with such a run.Since i used a stainless ballast i was able to adjust the ballast to match the series resistance of the copper run to make the diode work. This didnt work with the resistor, even with no ballast it took nearly 15 seconds using the same 25’18/2 run. Maybe someone can find an ideal run length vs ignition time on 10ohm carbon films.It is good to know that the resistor will work if we are patient enough. Now we have two good methods. Thanks.-Edit-After looking at theresistance for copper wireI knew something was bogus with my results. Turns out that a 25 foot run of 18/2 should have a total series resistance of .3255 ohm. This should not affect the ignition times as i had previously found. Further testing showed my experiments were done with a dead battery.With a good battery i was able to make the 10 ohm 1/4 watt carbon film resistor ignite in 3 seconds on a 25 foot run of 18/2 copper. 10 ohm = fast, cheap, and easy.

[youtube=http://www.youtube.com/watch?v=Cov7-XWUa18&w=470] DARPA has awarded an extension to AeroVironment for their work on the Nano Air Vehicle project .  The prototype seen above, called Mercury, is an ornithopter which means it flaps it’s wings. It is the first to show controlled hovering. Look closely, there’s no rudder or tail. Mercury uses the two wings for both lift and control. Ornithopters themselves aren’t new, we’ve even covered them before . Usually they use the flapping wings for propulson and a tail to steer as they travel like an airplane. We would really love to see some detail shots of Mercury. [via slashdot ]

[Kyle McDonald] sent in his latest project, a software keylogger that twitters what you type . He wrote it using C++ and OpenFrameworks . It logs each keystroke, then it posts to twitter 140 characters at a time. To protect himself, he set up a whitelist of private strings like passwords and credit card numbers that would be stripped before posting. If the twypewriter followed him, his keystrokes could be recreated. [thanks Kyle]

Mixed Voltage Interfacing With The Bus Pirate
Ian
[ "Misc Hacks", "Tool Hacks" ]
[ "bus pirate", "mixed voltage interfacing", "open collector bus", "pull-up resistors" ]
Most of the parts we use operate at 3.3volts, but we still run into a lot of old 5volt stuff, and an occasional 2.5volt or 1.8volt part. This post explains how to use the Bus Pirate’s open collector pin mode to interface with parts at different voltages. We’ve got more details and some example scenarios below the break. Yup, this is another Bus Pirate post. It’ll all be over soon though, because there’s a few days left to get your own Bus Pirate for $30, fully assembled and shipped worldwide. Overview The Bus Pirate has a normal pin mode and an open collector pin mode (also called high-impedance or HiZ). Normal pin mode can tolerate up to 5.5volts on input pins, but the output pins are fixed at 3.3volts. The open collector pin mode uses a pull-up resistor to set the bus voltage to something other than 3.3volts. Normal or open collector pin mode is offered as a configuration option after you select a protocol library in the Bus Pirate terminal (menu m). Some bus types always require open collector outputs with pull-up resistors, like 1-wire and I2C . The image above shows a representation of normal and open collector pin functions. Normal pin mode Normal pins switch between the positive supply voltage (high state, usually 1) and ground (low state, usually 0), in the Bus Pirate that’s 3.3volts and 0volts respectively. A normal pin is depicted on the left, switch 1 (S1) toggles the output between supply (V+) and ground (GND). Open collector mode In open collector mode, pins switch between a ‘disconnected’ state (high impedance) and ground (low state, usually 0). The voltage that signals a high state is supplied by a pull-up resistor (R1). Without a pull-up resistor the attached devices will never register a high state. We can feed any voltage into the pull-up resistors that the Bus Pirate will tolerate, so we can use this mode to interface devices above and below 3.3volts. An open collector output is depicted on the right. Switch 2 (S2) can only connect to ground. A resistor (R1) connected to the supply voltage (V+) holds the bus high. Most microcontroller pins are tri-state and become high impedance when configured as an input. This technique isn’t without disadvantages. The maximum possible bus speed is much lower, and the pull-up resistors use a bit of extra current. Make sure every device you connect can tolerate the voltage you plan to use, most 3.3volt devices don’t have 5volt tolerant pins. Usage examples Scenario 1 – Bus Pirate interfacing 3.3volt UART/SPI/JTAG/MIDI bus The Bus Pirate operates at 3.3volts, use normal pin outputs with no pull-up resistors. Scenario 2 – Bus Pirate interfacing 5volt UART/SPI/JTAG/MIDI bus The Bus pirate inputs are 5volt tolerant, but the output is only at 3.3volts. Use open collector outputs (HiZ) with pull-up resistors connected to the 5volt power supply. Scenario 3 – Bus Pirate interfacing 2volt UART/SPI/JTAG/MIDI bus The Bus pirate output is 3.3volts, which might damage a 2volt part. Use open collector outputs (HiZ) with pull-up resistors connected to the 2volt power supply. Scenario 4 – Bus Pirate interfacing a 1-wire or I2C bus between 1.8volts and 5volts 1-wire and I2C are bi-directional, open collector buses. They always require a pull-up resistor to create the high bus state. Use pull-up resistors connected to the 1.8volt to 5volt power supply.

The Snow Clock
Caleb Kraft
[ "Arduino Hacks", "home hacks" ]
[ "alarm clock", "arduino", "snow day" ]
Snow days are great, but generally you still have to wake up to find out if it is a snow day. [insingertech] decided to make a system to solve this problem. He made an alarm clock that would automatically de activate if school is cancelled . What a pleasant surprise it would be to just wake up and find that you had been allowed to sleep in. It is using an Arduino and a python script to control the state of the alarm based off of an online school closing announcement. You can download the software from the instructable.

Custom Car Door Keypad

[ "arduino", "arduino nano", "batchpcb", "car", "dodge caliber", "door lock", "keypad" ]
[Michael] has a keypad in his previous car’s door and he missed it enough to hack one into his Dodge Caliber . He bought a Ford keypad and mounted it inside his door with some custom electronics . He started with an Arduino nano to receive and authenticate button presses. This then splices into wires in the door that control the door lock. The program has a 5-digit code to unlock the door, but simply pressing 1 twice will lock the doors. He also implemented a lockout feature to prevent people from brute-forcing the combination. Although it isn’t wireless , it’s significantly simpler. [thanks Michael]

Parts: SPI EEPROM (25AA/25LC)

Microchip’s 25AA/25LC EEPROMs are data storage chips with a simple 3-wire interface. The 25AA/LC is an SPI version of the common 24AA/LC I2C EEPROM .  It comes in capacities of 128bytes to 128kilobytes. We looked at the smallest, the 128byte 25AA010A . There are Bus Pirate demonstrations for most types of serial EEPROMs. Check out our previous 1-wire ( DS2431 ) and I2C ( 24LC1025 ) EEPROM posts. Continue below to see our test circuit and a demonstration of the 25AA010 EEPROM. We used the Bus Pirate to play with this chip from our PC.  For a limited time you can get your own Bus Pirate , fully assembled and shipped worldwide, for only $30. 25AA010A SPI EEPROM memory, 128bytes ( Octopart search , $0.70). Datasheet (PDF). The schematic above shows a simple test circuit that should work with any 25AA/25LC SPI EEPROM. It’s a good idea to use a 0.1uF decoupling capacitor (C1) on the power pin in a real circuit, but we didn’t use one for our demonstration. We also connected the write protect (WP) and hold (HOLD) pins to the supply voltage (V+) to disable these features. Bus Pirate 25AA/LC (pin #) CS CS (1) MISO SO (2) MOSI SI (5) CLK SCK (6) V+ WP (3) V+ HOLD (7) V+ (3.3volts) VCC (8) GND GND (4) Vpullup VCC (8) We used our Bus Pirate universal serial interface to demonstrate this chip, but the command sequences will be the same for any setup. We connected the Bus Pirate to the 25AA010 as shown in the table above. We setup the Bus Pirate for SPI mode (M, 5) with normal outputs, and enabled the on-board power supply (capital ‘W’). 25AA parts work from 1.8volts to 5.5volts, 25LC parts have a 2.5volt minimum. We used a 3.3volt supply to power the chip, and interfaced it using the Bus Pirate’s normal 3.3volt pin outputs. You could also power the chip from the Bus Pirate’s 5volt supply. Interface the chip at 5volts by choosing open drain pin type (HiZ) during the mode configuration, then hold the bus high with pull-up resistors connected to 5volts. Interfacing Page 7 of the datasheet has a complete list of interface commands. This demonstration shows the minimum operations needed to write and retrieve data.

Up to 16 bytes can be written in a single operation. All writes must be on the same page of memory, see datasheet page 6 for details. EEPROMs larger than 256 bytes use 16 bit (2 byte) addresses.

Send the read command (0x03) and the address to start reading at (0x00), then read 5 bytes from the chip (r:5). The output should match the values we wrote earlier. *EEPROMs larger than 256 bytes use 16 bit (2 byte) addresses. Enter a two byte address such as “0 0” if you’re using one of these EEPROMs. Like this post? Check out the parts posts you may have missed. Want to request a part post?

Simplest Macro Hack Ever

[ "macro", "photography", "SLR" ]
This quick little hack is beautiful in its simplicity. Need a macro lens to play with ? Simply rip the lens out of a pair of binoculars and tape it to the end of your slr lens. The result is pretty good. If you need something a little higher quality, you could always hack an extra AF lens .

Bus Pirate Preorder Update

[ "bus pirate", "bus pirate order updates", "pre-order" ]
We’re only four days into the Bus Pirate pre-order , and we’ve exhausted the supply of PIC24FJ64GA002s available in Shenzhen. Thank you for supporting Hack a Day’s first official hardware pre-order. You helped make it a huge success, and we definitely want to do it again in the future. We weren’t kidding about the PIC shortage. Seeed sourced all they could from Shenzhen, and then tried Hong Kong. It’ll take 4 to 6 weeks to get more. If you already ordered a Bus Pirate then nothing changes, your Bus Pirate will ship ASAP. In fact, PCB production should start a few days early. The first pre-order item name starts with “[Preorder]”. New orders are now forwarded to a second pre-order. The new pre-order will take 4 to 6 weeks longer. It should ship about 6 to 8 weeks after July 3, 2009, but we’ll try our best to get it out sooner. The new pre-order item name starts with “[Preorder 2]”. Read more about the Bus Pirate in our latest How-to . Thank you again for your support!

Create Digital Music has a great post on [Luca De Rosso]’s OTTO . Built as part of his masters’ thesis, it’s a unique tangible music interface. You load a sample into the software which displays it on the instrument surface. The user can then manipulate the sample using various hardware inputs while watching the LED representation. The device uses just one Arduino for the display and inputs. It works with Max/MSP and is designed to give the performer only the information they truly need. You can find more pictures of the device on Flickr and a picture of the guts on CDM . Embedded below is the ‘Getting Started’ video that shows it in use.

Parts: ShiftBrite RGB LED Module (A6281)
Ian
[ "LED Hacks", "Misc Hacks", "Parts" ]
[ "blinkenlights", "bus pirate", "electronics", "led", "parts", "serial interface", "shiftbrite", "spi" ]
Macetech’s ShiftBrite is a high-power RGB LED coupled with an Allegro A6281 backpack. The A6281 uses three 10bit pulse-width modulators to mix millions of colors using the red, green, and blue elements in the RGB LED. Multiple modules can be chained together for bigger projects, like the ShiftBrite table . Below the break we demonstrate a ShiftBrite module using the Bus Pirate . For a limited time you can get your own Bus Pirate , fully assembled and shipped worldwide, for only $30. ShiftBrite RGB LED module ( Macetech , $4.99). ShiftBrite datasheet and example code , Allegro A6281 datasheet (PDF). The ShiftBrite module is a complete A6281 development board. It doesn’t require any extra parts, just a 5-9volt supply. The A6281 is one of the most complete RGB LED driver ICs, but it’s only made in a tiny QFN package. The ShiftBrite is a good way to try the A6281 without soldering a small chip. A bunch of A6281 modules can be chained together. Each module repeats all of the serial input signals on separate output pins, so the A6281 will work over long cable runs. Bus Pirate ShiftBrite MOSI DI CLK CI CS LI AUX EI 5volts V+ Vpullup V+ GND GND We used our Bus Pirate universal serial interface to demonstrate the ShiftBrite, but the command sequences will be the same for any microcontroller. We connected the Bus Pirate to the ShiftBrite as shown in the table above. We setup the Bus Pirate for raw3wire mode (M, 8), and chose open drain outputs (Hi-Z) so we can interface the ShiftBrite at 5volts. The Bus Pirate can’t output 5volts directly, so we enabled the bus pull-up resistors (menu ‘p’ in v2) and attached the pull-up resistor voltage input pin to the 5volt supply. Finally, we enabled the on-board power supply (capital ‘W’). Interfacing The LED driver output is only active when the enable pin (EI) is held low. RAW3WIRE>A <– capital ‘A’, EI pin high, output disabled AUX HIGH RAW3WIRE>a <– small ‘a’, EI pin low, output active AUX LOW RAW3WIRE> We used the Bus Pirate’s auxiliary pin to toggle the A6281’s enable pin, but you could also bypass this feature by wiring EI directly to ground. A small ‘a’ in the Bus Pirate terminal takes the AUX/EI pin connection low, enabling the LED output. Two commands update the A6281 settings. The configuration command controls dot correction and clock settings. The LED pulse-width modulator (PWM) command updates the three 10bit values that set the red, green, and blue channel brightness. Both commands are 32 bits (4 bytes) long, bit 30 selects the configuration or pulse-width modulator command. Refer to the chart above, or datasheet page 7. The interface protocol is like SPI , but the master-input-slave-output pin is unused. Data is sent most significant bit first, starting with bit 31. Commands are sent by clocking 32 bits into the chip and then toggling the latch pin. Before we can start mixing colors, we need to setup the A628a’s internal clock and write the dot correction values. RAW3WIRE>0b01000111 0b11110001 0b11111100 0b01111111 ][ WRITE: 0x47 <–write 32bits of data WRITE: 0xF1 WRITE: 0xFC WRITE: 0x7F CS DISABLED <–latch pin high CS ENABLED <–latch pin low RAW3WIRE> We wrote the values in binary so it’s easy to follow along in the table above. Remember that bit 31 is sent first, so the order of bits shown here is opposite of what is shown in the table. The complete setup command is 32 bits (4 bytes) long. Bit 30 sets this as a configuration command (1). Bit 7 and 8 configure the clock source, value 00 configures the 800KHz internal oscillator (datasheet page 7). Three 7bit ‘dot correction’ values fine tune the LED color channels if you want to correct a wonky pixel in a large array (see the register locations in the table above). We set all the dot correction values to full (1111111). Several bits trigger test functions or don’t have a purpose, these should be entered as 0. After entering 32 bits, toggle the A6281 latch pin (][) to lock the data into the register. Now that the chip is configured and the output enabled, we can finally play with the LED. RAW3WIRE>0b00111111 0b11111111 0b11111111 0b11111111 ][ WRITE: 0x3F WRITE: 0xFF WRITE: 0xFF WRITE: 0xFF CS DISABLED CS ENABLED RAW3WIRE> First, turn all the colors to full. Bit 31 (0) is ignored, bit 30 (0) indicates a LED pulse-width modulator update command, and the remaining bits set all three channels to 100%.  The three PWM values control the output intensity of each color as follows: blue (bits 29:20), red (bits 19:10), and green (bits 9:0). Raise and lower the latch pin (][) to end the command. Next, test each each color individually. RAW3WIRE>0b00111111 0b11110000 0b00000000 0b00000000 ][ WRITE: 0x3F WRITE: 0xF0 WRITE: 0x00 WRITE: 0x00 CS DISABLED CS ENABLED RAW3WIRE> Bit 30 (0) signals an LED PWM update command, followed by a 100% setting for the blue channel (1111111111) and 0% settings for the red and green channels. When we toggle the latch pin (][) the new values are saved and the LED color changes to blue. RAW3WIRE>0b00000000 0b00001111 0b11111100 0b00000000 ][ WRITE: 0x00 WRITE: 0x0F WRITE: 0xFC WRITE: 0x00 CS DISABLED CS ENABLED RAW3WIRE> This time we’ll set the LED to 100% red. Bit 30 (0) signals an LED PWM update command, followed by a 0% setting for the blue channel, a 100% setting for the red channel (1111111111), and a 0% setting for green.  When we toggle the latch pin (][) the LED color changes to red. RAW3WIRE>0b00000000 0b00000000 0b00000011 0b11111111 ][ WRITE: 0x00 WRITE: 0x00 WRITE: 0x03 WRITE: 0xFF CS DISABLED CS ENABLED RAW3WIRE> Finally, we set the LED to 100% green. Bit 30 signals an LED PWM update, followed by 0% settings for the blue and red channels, and a 100% setting for the green channel (1111111111).  Toggle the latch pin (][) and the LED color changes to green.

[youtube=http://www.youtube.com/watch?v=Zrb58Pcuos0] [Hunter, Kyle, and Dylan] sent us some information on their Barbie Web Rover. It’s an old barbie power wheels jeep that’s been converted to a web enabled remote control car. They ripped out the old drive train and tore out the steering system. The rear tires are now independently driven for steering. It’s using an Arduino to control the motors and an Acer Aspire loaded with linux for the higher functions. It’s cool that they mention the farthest test being over 1600 miles away, but when it’s web enabled, does distance really matter? They mention that the coolness factor is proportionate to the size and we have to agree, as long as they keep it small enough to not cause any real damage. You can build a web enabled rover with a little more effort from just a router , if you don’t want to give up your laptop.

[Spikenzie] has created an 8×8 LED array that fits inside an ikea frame . He multiplexed the 64 red LEDs on a PCB with connections on the back. He then used a MAX7129 , an LED multiplexer and driver, driven by a PIC over SPI to do animations and play pong. He then encased the array in laser-cut cardboard and white acrylic to get large dots. This entire assembly was then placed inside an Ikea RIBBA picture frame . The result is an aesthetic homebrew display that is easy to control. Related: 64pixels are enough

[youtube=http://www.youtube.com/watch?v=8ES61MbSmpc] The Motori plotter is fast and high precision. One image shows that it is drawing lines at .5mm. Like others in the flickr set, we keep thinking of how we could apply this to PCB creation. Great job [svofski]. If you want one that’s not as precise, but might have a much cooler drawing mechanism, you might want to check out the lego arm plotter we posted back in May .

[pc486] sent in his hack that uses an ATtiny85 to act like an EM4102, a chip used for RFID tags . Minimally, all that is needed is the AVR and a coil, but he recommends some filtering capacitors. Depending on the size of the coil, different frequencies and ranges can be achieved. This project actually includes several hacks, such as using the coil for not only power, but a clock signal. The coil is actually able to power the chip without being connected to the power pins due to clamping diodes on the connected pins. The firmware is short but available on subversion .

[youtube http://www.youtube.com/watch?v=mlLY0zic7u0%5D Embedded above is an interesting multitouch demo by [Lahiru]. The goal of the project was to find an easy way to retrofit current LCDs for multitouch . Instead of using infrared or capacitive recognition, it uses a standard webcam mounted overhead. To calibrate, you draw polygon around the desktop screen as the webcam sees it. The camera can identify the location of markers placed on the screen and their color. iDisplay can also recognize hands making the pinch motion and sends these as touch events via TUIO, so it works with existing touch software. It’s written in C++ using OpenCV for image processing with openFrameworks as the application framework. [via NUI Group ]

[youtube=http://www.youtube.com/watch?v=7vYKwih8Izk] Reader, [Ben Godding], sends in the video for his senior design team’s automated paintball sentry. The frame is made of plasma cut aluminum. The paintball gun uses a custom hopper mounted remotely from the gun body. It has two webcams offering a 160 degree field of vision, and the image processing is done by a dual core pentium CPU booting windows xp off a compact flash card. The computer interfaces with the 1/4scale RC servos using a PIC24. The paintball sentry can either be configured via a computer GUI when a monitor is available or a baclkit keypad and 4×20 charachter display in the field.

What it does is compare each new frame to a continuously updating “key frame”. If there is a difference in these two frames, it identifies it and calls the center of it the object. Then it tracks the object and outputs coordinates based on the prediction algorithm to Ben’s PIC24.

I made a “sentry” back in 1992 for my undergrad project that only used a 6809 and a spinning Ultrasonic rangefinder on a stepper sweeping a 110 deg window. I was able to get 0.5 deg resolution and 20 sweeps per second, it had a range of about 50 feet due to beam spread, we fixed that with using a slot on the receiving sensor.. it fired foam earplugs and used Co2.The target leading was simple based on input values and simply converting the complex math to integer math., my cohort had started to add a wind vane and cups to get input for windage and direction to compensate. Our only problem was it would not see you very quick if you rushed it straight without moving your arms and did not weave at all, a fault of our ultrasonic system.Today I would use a form of laser radar, far easier to put in place 100 times more accurate than any video based system.P,S.: you guys have it really easy with pic’s today.

Parts: I2C Real-time Clock Calendar (PCF8563)

[ "Misc Hacks", "Parts" ]
[ "bus pirate", "calendar", "i2c", "parts", "pcf8563", "real time clock", "rtc", "rtcc" ]
The PCF8563 is a real-time clock /calendar/alarm chip with an I2C interface . This would be useful in projects where the primary microcontroller doesn’t have enough resources for an interrupt driven clock. We demonstrate the PCF8563 using the Bus Pirate after the break. For a limited time you can get your own Bus Pirate , fully assembled and shipped worldwide, for only $30. PCF8563 real-time clock calendar ( Octopart search , $1.33). Datasheet (PDF). The schematic above shows a bare-bones circuit for the PCF8563. It requires a simple external oscillator circuit with a 32.768khz watch crystal (Q1). The oscillator input pin needs an external capacitor (C1, 12pF), but the oscillator output pin already has an internal capacitor. C2 is a 0.1uf decoupling capacitor for the power supply pin. The power supply can be 1.5 to 5.5volts. The datasheet also recommends a diode on the voltage input. We didn’t use this in our test. Bus Pirate PCF8563 (pin #) GND GND (4) MOSI SDA (5) CLK SCL (6) 3.3volts or 5volts V+ (8) Vpullup V+ (8) We used our Bus Pirate universal serial interface to demonstrate this chip, but the transaction sequence will be the same for any microcontroller implementation. We connected the Bus Pirate to the PCF8563 as shown in the table above. We setup the Bus Pirate for I2C mode (M, 4) , and enabled the on-board power supply (capital ‘W’). Don’t forget that you need pull-up resistors somewhere on the I2C bus. If you’re using a Bus Pirate, attach the Vpullup input to the circuit power supply then press p to configure the pullup resistors (or attach the pull-up jumpers for hardware v1a). Interface I2C>(1) <–search I2C address macro Searching 7bit I2C address space. Found devices at: 0xA2 0xA3 I2C> The PCF8563 I2C  write address is 0xa2, and the read address is 0xa3. You can find this in the datasheet, or use the Bus Pirate search macro (1) to check all possible addresses. Address | Register name | Bits 0x00 control_status_1 0x01 control_status_2 0x02 VL_seconds (0:6) 0x03 minutes (0:6) 0x04 hours (0:5) 0x05 days (0:5) 0x06 weekdays (0:2) 0x07 months (0:4) 0x08 years (0:7) (see datasheet page 6) This RTC has 16 one-byte registers that configure the clock, and set/retrieve the time. Bytes 0-8, shown in the table above, contain status and time information. The upper 7 bytes configure an alarm, timers, and other advanced features. We’re just going to focus on the clock functions. The registers are accessed just like an I2C EEPROM . Write values by sending the I2C write address (0xa2), the address to start writing (0-15), and the data bytes(s) to write. Read values from the chip in two steps. First, use the write command to position the read pointer, but don’t send any data bytes. Second, use the read address (0xa3) to read bytes starting at the position set during the write command. I2C>{ 0xa2 2 0 30 12 31 1 5 9 } I2C START CONDITION WRITE: 162 GOT ACK: YES <–I2C write address (0xa2=162) WRITE: 2 GOT ACK: YES <–register to begin writing WRITE: 0 GOT ACK: YES <–seconds (0) WRITE: 30 GOT ACK: YES <–minutes (30) WRITE: 12 GOT ACK: YES <–hours (12/noon) WRITE: 31 GOT ACK: YES <–day of the month (31) WRITE: 1 GOT ACK: YES <–day of the week (1/Sunday) WRITE: 5 GOT ACK: YES <–month (5/May) WRITE: 9 GOT ACK: YES <–year (09/2009) I2C STOP CONDITION I2C> Set the time by writing to registers 0x02 to 0x08. The values are entered in binary coded decimal format, with all numerical date representations being fairly standard (see datasheet pages 6-9). We set the time to 12:30:00 May 31, 2009. First, send an I2C start condition to tell the chip to listen for its address (Bus Pirate command {). Next, send the PFC8563 write address ( 0xa2 ), and set the write pointer to the seconds register ( 2 ). Finally, write 7 bytes of data to the time registers at addresses 2-8. End the transaction with an I2C stop condition (Bus Pirate command }). I2C>{0xa2 2 { 0xa3 r:7} I2C START CONDITION WRITE: 162 GOT ACK: YES <–send write address (0xa2=162) WRITE: 2 GOT ACK: YES <–set pointer to register 2, seconds I2C START CONDITION <–repeated start condition WRITE: 163 GOT ACK: YES <–send read address (0xa3=163) BULK READ 7 BYTES: <–read back 7 bytes 17 31 12 31 1 5 9 <–time: 12:31:17 Sunday, May 31, 2009 I2C STOP CONDITION I2C> We set the Bus Pirate’s output mode to decimal (menu ‘o’) before reading the time. This displays the values in the more familiar decimal format. Retrieving the time takes two steps. First, a partial write transaction sets the memory location to read. Then, instead of sending any data, send a second start condition ({) and the PCF8563 I2C read address (0xa3) to put the chip in read mode. Finally, read 7 bytes (r:7) from registers 2 to 8. The output shows that a minute has passed since we set the time. I2C>{0xa2 2 { 0xa3 r:7} I2C START CONDITION WRITE: 162 GOT ACK: YES <–send write address (0xa2=162) WRITE: 2 GOT ACK: YES <–set pointer to register 2, seconds I2C START CONDITION <–repeated start condition WRITE: 163 GOT ACK: YES <–send read address (0xa3=163) BULK READ 7 BYTES: <–read back 7 bytes 34 32 12 31 33 37 9 <–day of week (33) and month (37) appear wrong I2C STOP CONDITION I2C> Sometimes the chip appears to return garbage results. The above output is actually a valid time reading, even though it’s obviously not the 33rd day of the week or the 37th month of the year. Each register has several ‘do not care’ bits (see datasheet page 6). In most devices  ‘do not care’ bits are always set to 0, but the PCF8563 appears to use them in some time keeping capacity. Day of week reads 33, or 0b00100001 in binary. If we ignore the upper 5 bits we get 0b001, or 1/Sunday, the proper day of the week. Similarly, ignore the upper three bits of month (37 = 0b00100101), giving 0b00101 or 5/May. Like this post? Check out the parts posts you may have missed. Want to request a part post?

Pneumatic Bed Alarm Clock

[youtube=http://www.youtube.com/watch?v=kQ-l5PlDa-k] For four years, this guy has been using this Pneumatic bed alarm clock to wake up. Apparently “I’m a really heavy sleeper” is an understatement. It is computer controlled and runs from two seperate air sources. He entered it in a radio show contest and we’re guessing he won. You can see the test run at the radio station after the break. We really can understand the fun of building this. But actually using it for four years, without suffering any major injuries, is an accomplishment of it’s own.

Home Made Solder Pot
Steve Watkins
[ "home hacks", "Misc Hacks", "Tool Hacks" ]
[ "desolder", "diy", "solder", "soldering pot" ]
Our reader [Damir] built a home made soldering pot . It can be used to solder and desolder components. To remove a through hole component, the solder side is placed in the bath. Then the component is removed with pliers. It is also possible to solder components, by placing the leads in the molten solder; similar to wave soldering. Another common use is tinning self stripping wire. The insulation of the wire is designed to burn off, allowing the strip and tin phase to be single step. This solder pot would be a nice addition to the hacker’s soldering station we had covered in 2008. For more pictures, check out the photo gallery . In the video embedded below, a transformer is easily removed from a modem. [googlevideo=http://video.google.com/videoplay?docid=-291669304260217694&hl=en]

Update, Saturday July 4th, 2009: All preorders are closed. We’re excited to announce our partnership with the folks at Seeed Studio (home of the excellent Seeeduino ) to put the Bus Pirate v2go into production! The preorder period ends July 3rd. The price is $30 including worldwide shipping. The board pictured above is a hand soldered prototype, but the ones sold by Seeed are completely factory assembled. This is the first officially produced piece of Hack a Day hardware. Depending on its success, we’ll be able to put many future designs into production. Read more about the Bus Pirate in our latest How-to . Thank you for your support! ***Update, Monday June 29, 2009 : Wow, your support has been overwhelming! Thank you! There have been more orders for the Bus Pirate than we ever imagined. As of this update, there’s a few (12) Bus Pirates left in the Seeed preorder. After that, we’ve exhausted the supply of PIC24FJ64GA002s available in Shenzhen. If you’ve already placed your order nothing changes, the manufacturing process has already begun and your Bus Pirate will ship ASAP. After the first preorder is filled, Seeed will start a new preorder. The second preorder will be delayed until more PIC24FJ64GA002s are delivered, about 4 to 6 weeks. This order should ship about 6 to 8 weeks after July 3, 2009, but we’ll try our best to get it out sooner. Thank you again for your support!

How-to: The Bus Pirate V2 With USB
Ian
[ "Featured", "hardware", "how-to", "Tool Hacks" ]
[ "1-wire", "bus pirate", "i2c", "jtag", "midi", "pc keyboard", "spi", "the bus pirate", "uart", "universal serial interface" ]
Update, Saturday July 4th, 2009: All preorders are closed. The Bus Pirate is a universal serial interface tool, we use it to test new chips without writing any code. It currently supports most serial protocols, including 1-Wire, I2C, SPI, JTAG, asynchronous serial, MIDI, and more. We added some other features we frequently need, like pulse-width modulation, frequency measurement, voltage measurement, bus sniffers, pull-up resistors, and switchable 3.3volt and 5volt power supplies. The new v2 family adds USB power and connectivity to the best Bus Pirate design yet. We also reduced the part count and cost wherever possible. If you want to get your hands on some Bus Pirate USB goodness, Seeed Studio has assembled hardware for $30 (including worldwide shipping). Read about the new design after the break. Concept overview The Bus Pirate connects to a PC USB port. The user send commands to the Bus Pirate from a serial terminal on the PC. Commands are translated to the bus protocols that control microchips. See our Bus Pirate page for full documentation. The latest firmware supports 1-Wire, I2C, SPI, JTAG, asynchronous serial, MIDI, and PC keyboards. Bit-wise 2- and 3-wire libraries can interface most proprietary serial protocols.  More protocols are being added all the time, check out the source code on our Google Code SVN page . Hardware Click for a large image of the schematic (PNG). The schematic and board layout were made with the freeware version of Cadsoft Eagle . Download the latest files from our Google Code page. PIC24F A Microchip PIC24F series microcontroller generates the user interface and translates input into bus communications. V2 uses the same 24FJ64GA002 as the previous Bus Pirate versions. It’s cheap, has a ton of memory, a couple 5volt tolerant input pins, and the peripheral pin select feature lets us assign hardware modules anywhere we want. The PIC (IC1) is powered by a 3.3volt regulator (VR2, C23). Each PIC power pin gets a 0.1uF bypass capacitor (C1,2). The internal 2.5volt regulator requires a 10uF tantalum capacitor (C20). The programming pins are brought to a five pin header (ICSP) on the edge of the PCB. USB interface The Bus Pirate is powered from the USB 5volt supply, which is first filtered with a ferrite bead (L1) and 10uF tantalum capacitor (C21). We used the small, still-not-quite-common, USB mini-b connector (J2). Choosing a ferrite bead is a common hangup. Its purpose is to filter small power fluctuations, all the current for the circuit will go through it. We can guestimate that the Bus Pirate’s worst case current consumption is 525ma (3 power supplies @ 150ma, the FTDI chip @ 25ma, 2 LEDs @ 50ma max). Use a ferrite bead rated for at least 1000ma to be safe. We used this one , which is rated for 1500ma and costs 10 cents. An FTDI FT232BL USB->serial chip (IC2) handles the USB connection. You might be familiar with this chip from various Arduino boards. FTDI has extensive driver support for most platforms, we used the virtual com port drivers.  This is the latest generation chip, and it’s only available in small SSOP and QFN packages. We had no problem hand-soldering it to a professional PCB, but it’s not for everyone. The FT232BL is powered directly from the filtered, unregulated USB supply. C4 is a  decoupling capacitor for the FTDI232BL supply pin. A single LED (LED4/USB) indicates USB status and activity. The FT232BL RXLED pin sinks current, so we powered the LED from the 5volt USB supply through a 1.1K resistor (R3). While the FT232BL runs at 5volts from the USB supply, its serial IO pins have an independent supply input – they can operate at another voltage. Since the microcontroller is 3.3volts, we just feed the FT232BL IO pins a 3.3volt supply and eliminate any funky translation circuitry. We used the chip’s internal 3.3volt regulator to supply the IO pins because it was the easiest trace to route. The IO pins get their own 0.1uF bypass capacitor (C5). Switchable power supplies The Bus Pirate has on-board 3.3volt and 5volt supplies (VR3, VR4) that can power a test circuit. The supplies are switchable, so we can reset the circuit from software when something goes wrong. To be extra safe, the supplies are held off until activated in the terminal. [ Nathan Seidle ] at SparkFun recommended that we replace the TPS796xx ($2.50) we used in The Bus Pirate v1a with a MIC5205-xxYM5 ($0.90). They supply just 150ma maximum current, compared to 800ma from the TPS796xx, but the cost savings and reduced part-count are worth it. The regulators are fed from the 5volt USB supply. The 5volt regulator drops a few millivolts below optimal because there’s no headroom, but it’s within the minimum level specified by most 5volt parts. The MIC5205 requires a large output filter capacitor (C22-24, 10uF), but no input capacitor. An optional small-value capacitor on the BP pin can decrease power supply noise, but we left this off because it didn’t make much difference in practice. A small voltage on the EN pin enables the supply, we used a 10K pull-down resistor (R18, not shown) to ensure that the supplies stay off while the PIC initializes. LED3/VREG, with current limiting resistor R32, lights when the power supplies are active. On-board pull-up resistors Bus Pirate V2 has multi-voltage, software controlled pull-up resistors via the 4066 (PDF) quad bilateral switch (IC3). When enabled, the 4066 connects the four on-board bus pull-up resistors (R20-23, 10K) to any external signal on the Vpullup pin (0 to 5volts). When disabled, the outputs are high-impedance and have no effect on the bus lines. The 4066 can’t switch an input voltage greater than the supply voltage. To give it the widest possible range, we powered it from the USB supply (5volts). When operated at 5volts, it takes 4volts+ to enable the 4066. The PIC pins have a maximum output of 3.3volts, so we have a problem. We solve it with a 5volt tolerant PIC pin and a pull-up resistor.  We turn on the 4066 with a pull-up resistor to 5volts (R19, 10K), and then disable it by switching the connected PIC pin to ground. For a brief instant at power-on, the PIC pin is high-impedance and the 4066 outputs are active because the pull-up resistor holds the control pins at 5volts. This is a concern if the Vpullup input is connected to an external 5volt supply while the bus is connected to a 3.3volt device – the brief exposure to 5volts might harm the device. If you’re worried about this, make sure there’s no active power supply connected to the Vpullup input before powering the Bus Pirate. This isn’t a concern if you use one of the on-board power supplies for the pull-up voltage because they’re disabled at startup. Voltage monitoring Four voltage dividers (R10-17, 10K), attached to analog to digital converters , allow the 3.3volt PIC to safely measure up to 6volts DC. Two voltage monitors measure the switchable power supply output. One measures the Vpullup input voltage, and another connects to the external voltage measurement probe. Indicator LEDs Three LEDs indicate power, mode, and voltage regulator status (LED1-3). LED4/USB displays USB activity. There are pads for resistors R30-32 and LEDs 1-3 on the front and back of the PCB. Only one set should be populated. We put pads on both sides so the board could be mounted with the indicator LEDs abutting the top of an enclosure. V2a vs V2go Click for large schematic (PNG) and layout (PNG) images of the version 2a hardware. The Eagle layout files are available in our Google Code SVN . Bus Pirate V2a is a developer’s board. In addition to all the features of V2go, it includes a jack (J1) for an external power supply and an additional 5volt regulator (VR1).  A switch (S1) selects between USB power and the external supply. The FT232BL chip on V2a is powered directly from the USB supply, and is not connected to the external supply. This is useful if you want to disable USB and use the Bus Pirate with a serial port on a PC or PDA. The V2a 4066 enable pull-up resistor is powered by the switchable 5volt regulator. The 5volt regulator must be enabled for the 4066 to be active. Don’t forget to install the 4066 pull-up resistor (R19), located on the back of the v2a PCB. PCB The PCB is a compact, 2-layer design. We prepared gerbers and had PCBs made by our usual service, BatchPCB ($21, shipped to EU), and tried a new service offered by Seeed Studio ($32, shipped worldwide). Seeed has a PCB service specifically for open source hardware projects. For $32 (including worldwide shipping) we got 5 small PCBs, and Seeed made a few extra to sell in their shop. We liked the idea that there would be extra PCBs available. You might know Seeed Studio from their cheap, improved Seeeduino Arduino clone. They’re located in Shenzhen, a Chinese electronics manufacturing hot-spot. A bunch of notable bloggers recently visited the region and wrote about the huge electronic component markets . The Seed order arrived in 14 days (left), the BatchPCB order arrived in 30 days (right).  Seeed and BatchPCB both make beautiful PCBs. Seeed has a much faster turn-around, and has better minimum trace widths and separation (8mil vs 6mil). BatchPCB has standard green PCBs, Seeed gives you the choice of green, black, or white; red, blue and yellow are $7.50 extra. We really like the Seeed PCB service, extra Bus Pirate v2go and v2a PCBs from our order are available in the Seeed shop. BatchPCB remains the cheapest prototyping option if you want a single board, closed source work, or don’t mind the extra wait.

The code is written in C, and is compiled with the Microchip C30 demonstration compiler . Bootloader The biggest change in the latest firmware is the addition of a bootloader . Now the firmware can be updated through the USB or serial connection. A bootloader is small program that sits at the beginning of the PIC program memory. It accepts updated firmware through the USB or serial port and saves it to the chip. The bootloader comes from Microchip application note AN1157 . We modified the bootloader to check for a jumper between the programming clock (PGC) and data (PGD) pins at power-up (update, above left). If there’s a connection, the bootloader takes over and waits for new code. Without a connection, the bootloader exits and runs the main program. There’s a very minor chance of accidentally entering the bootloader with no jumper installed. This won’t damage the Bus Pirate, but you will need to connect it again.  You can prevent it by moving the jumper over one position,  between the ground pin and the inner programming pin (normal, above right). Upgrading the firmware with the bootloader If you’re using a fresh chip, first program it with the bootloader firmware (vxx-PIC Bootloader.hex) through the ICSP header using a ‘real’ programmer like an ICD2 or PicKit . If you’re upgrading, follow this procedure or refer to the instructions in the firmware download. Disconnect the Bus Pirate from any power supply such as the USB cable. Place a jumper between the programming data and clock pins of the ICSP header. This will trigger the bootloader mode. Connect the Bus Pirate to a USB port (or, if applicable, power and serial cable). Start the MS Windows P24QP.exe programmer utility. You may need to modify the COM port (portindex=) in P24qp.ini to match your system.  Programmer source is available, and the simple bootloader protocol is documented in AN1157 if you want to write an app for a non-Windows system. Click the connect to device icon (#1). The program will connect to the PIC. Click the folder icon (#2) and open the firmware update file (vxx-Firmware for BL.hex). Click the erase device icon (#3) to erase the chip. DO NOT SKIP THIS STEP. Programming may not be successful if you forget to erase the chip. Click the write device icon (#4) to program the new firmware. Ignore any verify errors between 0x400 and 0xBFF, the bootloader lives in this region and doesn’t get updated. Click the green arrow icon (#5) to exit the bootloader and start the program. Click OK at the warning, we use the jumper to re-enter the bootloader. Remove the jumper from the programming pins, or move it over one position to connect the inner PGx pin to ground (GND). ***IMPORTANT*** Now restart the Bus Pirate by disconnecting and reconnecting the USB cable (or power cable). Some features won’t work until after a complete hardware reset. Using it USB device driver You may need to install an FTDI virtual serial port driver for your platform. On Windows, go to the Device Manager to configure the FTDI driver or check the COM port number. Menus and Syntax Use a serial terminal to communicate with the Bus Pirate. We like Tera Term . The Bus Pirate works best with the terminal set to 115200bps, 8 databits, no parity, 1stopbit. Disable local echo in the terminal, and use CR for line breaks. Some modes also require Xon/Xoff software flow control. In the serial terminal, press ? for the help menu. Read more about the Bus Pirate’s menu and syntax on the Bus Pirate page . There’s lots of demonstrations in our recent parts posts . LED indicators PWR indicates power to the Bus Pirate. MODE is off when the I/O pins are in a safe, high-impedance state. MODE is lit when a bus mode is engaged, the pins may be active. VREG indicates that the on-board switchable power supplies are active. UR is a single USB activity indicator LED. It displays data coming from the PC to the Bus Pirate. You can probably change what this LED displays with the FTDI configuration utility . Connections Pin location diagrams: v2a , v2g0 . Pin name | Description (Bus Pirate is the master) MOSI Master data out, slave in (SPI, JTAG), Serial data (1-Wire, I2C, KB), TX* (UART) CLK Clock signal (I2C, SPI, JTAG, KB) MISO Master data in, slave out (SPI, JTAG) RX (UART) CS* Chip select (SPI), TMS (JTAG) AUX Auxiliary IO, frequency probe ADC Voltage measurement probe (max 6volts) Vpu Voltage input for on-board pull-up resistors (0-5volts). +3.3v +3.3volt switchable power supply, max 150ma +5.0v +5volt switchable power supply, max 150ma GND Ground, connect to ground of test circuit Notes: * TX moved from CS to MOSI in firmware v0g. The 10 pin I/O block contains the data signals and power supplies that connect to a test circuit. Each pin is labeled on the back of the PCB, refer to the table above for a detailed description. The pinout on V2 is similar to V1, but we moved the power supply output and Vpullup input to the cable bundle. We also eliminated the second, unused auxiliary pin. Conclusion If you want a complete Bus Pirate or a kit, here’s a couple options: Seeed Studio is accepting pre-orders for assembled Bus Pirate v2go hardware until the end of Friday, July 3.  An assembled Bus Pirate v2go is $30, including worldwide shipping. Seeed Studio also has the extra v2g0 ($5.90) and v2a ($6.50) PCBs from our order. Fundamental Logic sells a through-hole kit version of the Bus Pirate V1a ($29.50). ***v1a is serial port only*** Thanks to everyone who contributed to this project. The Bus Pirate wouldn’t be possible without a ton of great feedback from the comments. If you’d like to get involved, join the Bus Pirate project at Google Code. Hack a Day review disclosure : We asked Seeed Studio to make our first order of PCBs for free. Since then, we’ve made several paid orders.

[Alex] of tinkerlog created a set of 64 RGB fireflies that synchronize to blink all at once. We covered the kit earlier , but he has assembled a set of 64. Each firefly is independently controlled by an ATtiny13 that reads a phototransistor and lights up an RGB LED. The fireflies are programmed to blink a certain rate, but blink faster if they detect other blinks . After a few cycles, the fireflies begin to blink in unison. When the fireflies are arranged in different configurations, different patterns emerge. He is selling kits and has instructions for building your own . Videos of the fireflies after the jump.

[Jay] hacked a Blu-Ray laser diode into a keychain enclosure . He found a heavy brass keychain light from Lowe’s and stuffed the diode and a larger battery inside. The existing batteries weren’t powerful enough, so he drilled out the endcap to fit a 200mAh 3.6v lithium battery inside. He also modded the power button to only momentarily turn on the diode. With the larger battery, the laser can run for about an hour between charges. In addition to a Blu-Ray lasers, he also has versions with a 200mW red diode. Related: Laser projector zippo

He was one of the very first people to buy a 6x bluray burner only to tear it apart for its diode. He has the utmost respect of the members of LPF, and I can testify his pictures are not faked. Some cameras pick up bluray differently than others, and the addition of smoke to the air *greatly* increases the visibility of the beam. Beamshots like these aren’t uncommon.

Bus Pirate Firmware Update V0g
Ian
[ "hardware", "News", "Tool Hacks" ]
[ "bus pirate", "firmware", "open source", "software", "software updates", "updates" ]
Firmware v0g for all Bus Pirate revisions is now available. Updates in this release include a bootloader, frequency generator/pulse-width modulator, SPI bus sniffer, MIDI library, configuration reports, improved user interface, and bug fixes. v0g is also the first firmware to fully support the v2 hardware branch. We’re really proud of this release as it brings a much more consistent structure to the internal operation of the Bus Pirate. It lays the foundation for future CAN, LIN, and OBDII libraries, and it supports localization and translations.  Install and upgrade instructions are included with the firmware. Report bugs on the project issue tracker . We document the new features after the break. Bootloader Firmware v0g includes a bootloader . After the bootloader is installed, firmware updates can be done over the serial or USB connection, instead of using a proper ICSP programmer. Install and update instructions are included in the firmware archive. Frequency generator/pulse-width modulator 1-WIRE>g <–frequency generator/PWM setup command 1KHz-4,000KHz frequency generator/PWM (beta) FREQUENCY in KHz (50) >50 <–enter frequency in KHz PRESCALE:8 <–calculated prescaler PR2:39 <–calculated PR2 value DUTY CYCLE in % (50) >50 <–enter percent duty cycle PWM ACTIVE 1-WIRE>f <–frequency measurement command PWM ACTIVE: DISABLE PWM <–not available when PWM is active 1-WIRE>g <–g again to disable PWM PWM DISABLED 1-WIRE> A 1Hz-4MHz frequency generator /pulse-width modulator function is available on the auxiliary pin using menu option ‘g’. This feature is still in development, but v0g has the essential functionality.  The frequency generator and frequency measurement features can not be used at the same time. We also squashed a small bug in the frequency measurement code for hardware v1+. SPI bus sniffer SPI>(1) <–sniffer macro Sniff when: 1. CS low 2. CS high 3. All traffic (1) >3 <–when to sniff bus SPI BUS SNIFFER, PRESS ANY KEY TO EXIT 0x10(0x00) 0xC6(0x00) <–displays data as MOSI(MISO) SPI> The PIC24F’s SPI slave mode made it easy to add an SPI bus sniffer . It works fine on slow or intermittent data transmissions, but it needs additional output buffering for better performance at high speeds. For the best performance, change the Bus Pirate display mode to ‘raw output’. MIDI library MIDI, a popular interface for musical instruments, is simply a 33.2K baud/8/N/1 UART.

Wide Angle Lense Mod For The ATC2K
Caleb Kraft
[ "digital cameras hacks", "Video Hacks", "Wearable Hacks" ]
[ "camera", "lens", "submarine" ]
For those that have them, the ATC2K action camera is a decent little piece of equipment. It is waterproof and can save video for roughly 30 minutes on a flash card. The viewing angle of the lens leaves something to be desired though. This has been remedied in newer models. [raalst] shows us how to modify the ATC2K to install a new, wider angle lens , while retaining the waterproof seal.  He also takes us through a necessary mod to ensure clear video under water since the new lens was not initially intended for it.  Just in case you are curious, he’s using his for hobby radio controlled submarine dives.

[youtube=http://www.youtube.com/watch?v=6mKjRakndSk] [Mike] really liked the thought of the Monome, especially the green aspect of their construction. He felt he could take it a step further. After 40 years of electronics tinkering, he had quite a spare parts box. He constructed his monome clone from stuff he just had laying around .  All of his pieces were either rejected samples from his company or outdated parts destined for the trash bin. Great job [Mike]. If you are planning to build one and don’t have the buttons laying around, you can get a more typical monome look and feel by going with the sparkfun RGB pads, like we did back in March.

Hackit: Boxee Now On Windows

[ "HackIt", "home entertainment hacks" ]
[ "alpha", "apple tv", "boxee", "ces", "HackIt", "media center", "mythtv", "plex", "xbmc", "xbox" ]
Boxee , the free media center management and streaming application, is now available for Windows platforms . We’ve been following the developments of Boxee since we first announced its alpha this time last year. At that time, it was only available for OSX with promised Ubuntu support. We were a bit skeptical about the interface noting, “Unfortunately all the dynamic resizing, animated, sliding, floating info boxes make it behave like the zooming user interface’s retarded cousin”. Our interest in Boxee was almost entirely based on it being a fork of XBMC, the media center project developed for initially for hacked Xboxes. It was interesting to see Boxee become the interface of choice for hacked Apple TVs and then go mainstream with a big push at CES. Have you been using Boxee as your media center? What do you love/hate? What about alternatives like XBMC , Plex , or MythTV ?

Best starting point would be a netbook distribution, with the special big-iconed desktop. Just stick some nice bling on it (compiz), and clean up the UIs of your favorite apps (big fonts and no menu in Firefox, less panels in the audio player, automatic full screen in the video player, *some* kind of good video indexing. Hint, the file manager’s preview does not do it. I want tags and IMDB sync. Also super nerds might want to control their DVD juggling robot from the couch.)To top it of with a nice diss: these media center apps remind me a lot of KDE. Both have endless configurability, mostly concerning skins, and very minute details of user experience that allow one to change everything that does not suck about it but leaves the big problems.I do not want to have a seperate media library, that comes with it’s own update horrors (yo people there is inotify and plain ol’ file tree walking. Do it both and don’t bother me.)I do not want to have to setup an SQL database server, and have stupid questions asked about it too. Hell it’s not an enterprise app. It’s for watching porn. Just slap it in a SQLite DB and be quiet about it.I do not want to wait three hours for some scan to finish before I can enjoy (or not) the media. I also do not want to have to rescan for the same three hours on every startup, because the media center crashes when I told it I had an DVB-S receiver while that PCI ID was in fact the one of my GPU.Honorable mention: Kaffeeine was the only, and that is evidence of what a giant suckfest this is, the only application that did not cause me endless pain with my DVB receiver. It worked out of the box. Scan the channels for 5 minutes, no questions asked, watch and record things, have timeshift. Everything worked (well, everything I care about. It seems that in the nether parts of the applications they included amarok in full, just to make sure).Well except the streaming via LAN (and thats also my point: its a graphical desktop app. Why the hell does it include a video streaming server! Who serves streams from a desktop app. That’s crazyness. It would be borderline OK if it allowed to remote control a stream demon, but that’s a specialized application’s job), and it has this funny error “Installation failed: Codec already installed”, when the user, god forbid!, installed a codec without Kaffeeine nodding it off.Arr!

It’s ok at playing back and managing videos that I’ve gotten from other sources and put into the right folder on the myth system, but again it suffers from the clunky UI at times.

The EVIC is a computer controlled internal combustion engine , utilizing a cam less solenoid actuated valve system. In addition to intake and exhaust valve control, the processor also handles ignition timing. With dynamic valve timing, it is possible to make an engine more efficient. Where a classic combustion engine would wastefully burn fuel, the EVIC can skip power cycles which are not needed. By increasing the valve duration, the CPU enables easy starting. The latest is the EVIC Mk3 which adds an exhaust valve sensor, and 3:1 solenoid leverage. There is a photo gallery with several EVIC engines . The Mk2 Twin is demonstrated in the video embedded below. [youtube=http://www.youtube.com/watch?v=GGnT58gRAz8]

These solenoids would be enduring tons of abuse in this application.In addition, if a fuel delivery solenoid/injector fails there is just no fuel delivered, but if one of these fails when controlling a valve there could be catastrophic issues due to the compression present within the cylinder.

Wireless Arduino Cat Food Dispenser

Reader, [Andres Leon], has two adorable cats with very specific dietary needs. Instead of altering his schedule, he donned his hacking hat and designed a very solid cat food dispenser . The dispenser consists of a rotating drum with a slot in it and a PVC pipe Y-fitting to distribute the food evenly. The brains of the machine is an Arduino Deumillanove and an XBee module. The unit can be controlled by a web interface or it can run completely standalone. [Andres] ran into a problem where the drum’s resistance to turning varied based on how much food was inside. He solved this with a clever laser position indicator. A piece of plywood is lined up with the slot at the top so that whenever the slot is facing up it keeps the laser from shining on a photoresistor. The cats were afraid of the servo noise at first, but now they run to their bowls whenever they hear it.

Magic Lantern For Canon 5D

[ "digital cameras hacks" ]

[vimeo http://vimeo.com/5267475%5D [Trammell] has released a new firmware for the Canon 5D Mark II DSLR geared toward film makers. The stock firmware was very limited on the audio side. This firmware adds features such as live VU meters, reduced audio noise, and crop marks for filming in different formats. The firmware is written in a manner that it can be extended fairly easily. Hopefully this will turn out to be as helpful as CHDK has been for point and shoot cameras.

[youtube=http://www.youtube.com/watch?v=fbIzhlZHJfk] Lexlrie is basically a feed display . It can connect to twitter, facebook and we feel fine for its updates. What makes this project different is that it is supposed to alter its lighting based on the mood of the updates. The system looks for words like “better” and “sorry” and displays color patterns based on those. We have no idea what “better” should look like, but it’s a cool idea. You can get more details of its construction here . This project vaguely reminds of Pulse , which intended to show the emotion of blogger.com updates.

The Holy Toaster Kit

[ "home hacks", "Misc Hacks" ]
[ "diy", "jesus", "open source kit", "toast", "toaster", "toaster mods" ]
The holy toaster is an open source kit to put Jesus on your toast, complete with cost breakdown and engineering data files. A laser machined stainless steel Jesus blocks a pattern of radiation from browning the toast. Installation is quite simple. Use a pair of pliers to bend a few tabs for support, and then insert the pattern in the toaster. Browning adjustments may be required to obtain adequate contrast. Best results appear to come from Honey Bran Country Bread. Their Flickr page contains more photos and a video of the prototype being cut. Let everyone know about your divine toast with the twittering toaster we had covered in 2008. Below is the instructional video. [youtube=http://www.youtube.com/watch?v=4SQGMTnnUnM]

The iPhone dev-team has released Ultrasn0w to SIM unlock the iPhone 3G running the 3.0 firmware. It’s available via Cydia, which installs when you use the recently released PwnageTool to unlock the 3.0 firmware. There doesn’t seem to be any caveats besides advising T-Mobile US users to turn off 3G before install.

[ "gyro", "IMU", "nunchuck", "wii", "wii motion plus", "wii nunchuck", "wiimote" ]
[knuckles904] was able to use the new Wii MotionPlus with an Arduino. Nintendo has released the WM+ in order to detect the motion of the controller better. The Wiimote only detects acceleration, whereas the WM+ detects rotation along 3 axes. The Arduino communicates with it over I2C, the same protocol that is used with the Nunchuk. To connect the two devices, he used jumper wires, but breakout boards are also available. He was able to create some example code with help from wiibrew.org . When paired with a Nunchuk, which contains a 3-axis accelerometer, you can have a 6 degrees-of-freedom IMU for under $40, perfect for controlling your robots or logging data . [via adafruit ]

How-to: Build Your Own Spot Welder

Spot welders are used in the fabrication of automobiles, PC cases, power supplies, microwave ovens, electrical junction boxes, Faraday cages, and various electronics. A spot welder is used because it produces a highly defined point of contact weld. The materials are welded without excessive heating, so working pieces are handled easily. The weld is also highly controlled and repeatable. In this how-to we cover the basics of a spot welder, and then show you how to build one from a microwave oven transformer. A spot welder’s electrodes serve at least three functions. They transfer electrical energy to the material while also holding it together; this also controls resistance. The greater the pinch force the less the resistance, which results in decreased resistive heating. A lesser pinch force results in increased resistive heating. The electrodes also conduct heat away from the material, while in the off cycles, helping to cool and temper the weld. A resistive spot weld is commonly referred to as a ‘nugget’. Spot welders are generally confined to ferrous materials which somewhat limits their application range. Most produce a weld with low voltage and high current. The welder in this How-to operates from a secondary of 3vac. The primary is 120vac line voltage that should be treated with respect. The low voltage secondary makes the welder very safe, so the electrical shock hazard from the electrode is virtually non-existent. There is however the risk of burn due to the high temperatures as with any welder. This particular welder is not intended to weld a body panel on your 1966 Jeep; it will not work well on material heavier than 20gauge sheet metal. The intended use is for small projects, for it is not capable of continuous operation. Possible uses are as follows: Welding electrode material for electrolysis cells . Working with the fine components of a vacuum tube . Building a light weight frame for a small robotic platform. Most of us have enough parts laying around to build a spot welder. If you have a microwave oven transformer (MOT) laying around, then you are half way there. On a related note, we had covered a microwave oven arc welder in 2006. We also needed some heavy gauge copper wire. We used about four feet of 4AWG wire to build the spot welder in the photo. Other materials included scrap 2×6, 2×2, two copper screw type lugs, two copper welding cable lugs, two MIG welder tips, two 4″ x 3/4″ zinc plated corner braces, drywall screws, and three washers. Pictured above is a working MOT. The first thing we had to do was remove the secondary coils. Namely the high voltage winding, and the low voltage winding. We used an angle grinder with cut off wheel while being careful not to cut the primary winding. We cut the secondary flush with the MOT laminate core . Both sides of the MOT should be cut. Inspect the MOT for signs that the laminate has been welded. We have found that welded MOTs can handle a little more abuse than their sealed only counter parts. If possible try to keep the core insulation intact, where the secondary will be wound. Though it is not a show stopper if the insulation becomes damaged. The insulation makes it a little easier to wrap the heavy gauge secondary. After removal of the secondary we had something that resembles the above photo. If the magnetic shunt material falls out be sure to replace it as it was before. The shunt keeps the core from transferring too much power to the secondary. A magnetic ballast if you will. The shunt acts to control the saturation of the core. A brute force project like this relies on such a shunt for proper operation. Rewinding a MOT with 4AWG is no walk in the park. If you’ve damaged the core insulators, we suggest wrapping a layer of electrical tape in their place. This will help to avoid damaging the insulation on the wire as it is pulled through the core.  Our experience is that 3-4 windings is plenty. After all, this spot welder relies on high current and marginal resistance. Not high voltage. We were careful to ensure that the secondary coil was wrapped in a helical manner to complete the secondary. We mounted the MOT and 2×2 to the 2×6 base. This particular build used 12″ 2×6 with two 7″ 2×2. These dimensions may or may not work depending on the physical size of your MOT. The only critical part here is keeping the wire length as short as possible. After the lower jaw was mounted, we also attached the corner braces. It was found that a spare piece of 2×2 as a shim worked well to align the upper and lower jaw. After the upper jaw was aligned we attached it to the corner braces with screws. This formed the hinged portion of the jaw. The picture above shows the MIG welder tip and the screw type copper lug. This is an improvement from an earlier model we had built. Initially, we used copper tubing with a hole and a piece of 6AWG grounding wire serving as the welding electrode. The grounding wire was held in place by a screw that threaded inside the copper tube perpendicular to the electrode. It was very crude, but it worked. This new method is much more practical. Here are the two electrodes ready to be fixed to the lower and upper jaws. We double checked the MIG electrodes to make sure they were tight. A loose connection will take heat away from the weld nugget . Evenly aligning the welding electrodes, we were careful to keep the upper jaw in the natural position where it was mounted. This maintained a flat contact area for the welding electrodes. After we were sure that the electrodes had been properly aligned, the jaws were marked. We then drilled a small hole. Since we mounted with the grain of the 2×2 the holes helped to protect from splitting the 2×2. With the electrodes mounted, we cut the wire to proper length. We never cut the exact amount we need. We always cut more than we need. This rule of thumb should apply to all electrical wiring. After all it is much easier to cut off excess than wrap a new secondary. We bent the wires in to the approximate positions in which they were to be assembled and stripped the wire in preparation for the crimp type welding lugs. It is a good idea to strip more than is needed here as well. Simply cut off excess after sizing up the lugs depth. Never crimp insulation with the lug. This will create a potential problem area due to the loss of conduction. Using a good non insulation crimp tool to secure the wire. We inspected the crimp and gave it the tug test. Simply tug on the wire if it is loose it will pull out. It if doesn’t pull out then an adequate crimp suitable for high current has been made. The crimped wires were attached to the welding electrodes with screws. We were careful not to over tighten the screws. If a drywall screw had stripped out of the wood, we would have had to use a larger wood screw in its place. After both welding electrodes were fixed to the jaws, we aligned the electrodes. Using pliers we bent the electrodes so that they contacted each other evenly. The electrodes should be fairly close already since they were aligned before drilling. We opened the jaws and wired the primary to an electrical cord and then tested the secondary. If the breaker trips, check for the following: The secondary is  shorted (the jaws are closed) The magnetic shunts are missing or not properly reinstalled Faulty line wiring to primary or shorted primary Too much load on the circuit of test or undersized breaker We observed proper electrical wiring practices. It is also stressed that this is a welder and it should have a dedicated circuit as any other welder would have. With the power physically disconnected we verified the welding electrode alignment with the material we intended to work on. Before connecting the power and performing an initial weld, we observed a few safety guidelines. This is a welder and will produce very high temperatures. Keep fingers away from the welding electrodes. Allow the material to cool prior to handling. Always wear eye protection. You may be interested in reading about spot welder parameters . There’s also the problem of combustible materials… This Compaq used very thin aluminum to support the screen and connect the hinges. The metal broke and destroyed most of the lower plastic. We were able to make new supports from 22AWG stainless steel sheet metal. All the welds were made using the spot welder with a special power controller. The power controller will be covered in another how-to. [youtube=http://www.youtube.com/watch?v=VG1xVNpm7k8]

Also:> We cut the secondary flush with the MOT> laminate core. Both sides of the MOT should> be cut.Aren’t you just removing the coil on one side of the mot? What does “both sides” mean here?3.

Is it that beige material around the core inside the primary?4. > We observed proper electrical wiring practices.Could you elaborate on this? I’m clear on standard practices but I’d like to make sure on the details in this case?5. Safety question: Does a spot welder have radiative emissions that are dangerous to the eyes? In other words, is some sort of UV/IR protection necessary? You say safety glasses, but I wanted to double check that something like welding goggles weren’t necessary.6. Another safety question: If getting the mot out of an old microwave, what precautions should be taken concerning the possible Beryllium oxide on the magnetron?

The first, is the primary. This is what takes juice from the wall and energizes the core. The next is the high-voltage secondary. The produces a couple of thousand volts for the plate in the magnetron. The third winding, consisting of no more than three or four turns of wire, is the low-voltage secondary, and is used to light the filament in the magnetron. The instructions could probably be worded more clearly, like, “remove all the windings except the primary.”2) This just reflects the author’s technique for getting rid of the windings in the secondary. If you cut away the exposed windings on both sides of the core, all that’s left to do is to use a piece of dowel to punch out the wire strands still stacked in the core. BTW, I have found that a sharp wood chisel and a mallet does a fine job of cutting away unwanted windings, and produces less debris than a hacksaw.3) The magnetic shunts are little pieces of metal wedged into the the opening in the core. Most times, when you are hacking an MOT for a power supply application, you want to remove these, because they degrade regulation. In this application, I think I’d agree that they need to remain in place.4) Do what you can do to eliminate electrocution hazards. All the connections on the 120 VAC side should be well insulated. Power should be supplied with a heavy 3-wire cord, and the core of the transformer grounded. Also, since the primary windings are largely exposed, the entire transformer should probably be enclosed in a box with grills and a cooling fan. A would also fuse the primary side.5) I would be concerned about UV. I wouldn’t use a piece of equipment like this without eye protection.6) I’m not certain that beryllium is used in these tubes any longer.

It plugs into the dock port and allows you to control the track and volume with simple gestures. While accellerometer equipped units can already “shake to shuffle”, they lack the ability to simply skip tracks forward or backward. He notes that with an accellerometer, simple gestures can be harder to decipher than with a gyro. The gyro gives the ability to tell which direction you are twisting it, so it’s easier to utilize. [Benjamin] was previously covered when he released the iPodGPS .

Ars Technica writes about three new toys coming out this year : a sub 100$ projector, tv game, and night vision goggles. The projector runs at standard TV resolution, takes standard composite in, and outputs an okay picture. The night vision goggles are monocular but focus both eyes on a single RGB LCD. The goggles uses an array of IR LEDs instead of amplifying ambient light to see in the dark. Lastly, they have a standalone implementation of the arcade game Big Game Hunters. The rifle uses a sensor bar to do the motion tracking and features a 32MB rom to hold the game files.

Induction Furnace

[ "eddy current", "electronics", "high frequency", "inductive heater", "MOT", "water cooled" ]
[Tim Williams] made his own induction furnace . A copper tubing coil forms the primary winding, as the material to be heated becomes the short circuited secondary. The load material is subject to high power magnetic fields operating at radio frequency. The rapidly changing field induces current flow within the material, creating a great deal of heat. The brute power required a cooling system to match. In the video below, the induction furnace can be seen melting common table salt. [youtube=http://www.youtube.com/watch?v=ctPtOONtGGg]

Reader [Bradley] sent in his ArduiNIX project, an Arduino shield designed for driving nixie tubes . The shield allows the Arduino to drive and multiplex nixie tubes without any additional hardware. These antique-looking displays are commonly hacked into clocks . It takes 9 volts from a wall wart and steps it up to over 200V in order to drive the displays. The shield is capable of multiplexing up to 80 individual elements. He has example code for driving a 6-digit display and a clock on his site. He is selling kits and completed shields too.

Our friends over [adafruit] recently released the Sensor Pack 900 , a collection of parts for anyone who is interested in using analog sensors with their projects. The pack includes 9 sensors. They range from simple thermistors and hall effect sensors to sharp distance sensors. Also included in the pack are 3 unidentified components that can be used to interface with the analog sensors in the pack. At only $30, the Sensor Pack 900 seems to offer a great set of introductory components for anyone prototyping a new device.

[Chris-Koopa] sent in this sweet little throwback to the good ol days of Atari 2600. He had been playing his old unit, lamenting the poor visual quality on his new TV when he had an idea. He picked up an Atari flashback2 and began modding . He added a cartridge slot and made some case modifications to make it look more like the 2600. The final result is that he can switch between the built in games, or play strait off of the cartridges with crisp clean video. There are other methods of doing this, like modding the Atari itself or building a whole new console , but this is pretty sweet too.

[youtube=http://www.youtube.com/watch?v=7Ym0tZSWGMc] Many of you have probably experimented with alternative gaming interfaces. Here’s a well done little hack where they created a gun with a display mounted on it, for video gaming .  At a glance you can probably figure out exactly what they’ve done. They’ve attached a gyration mouse to the gun for tracking and gutted a keyboard for the buttons.  We have to give them some credit, they seem to have packaged it all nicely. Since it’s a standard mouse and keyboard, it just plugs in and works with any game.  As you can see in their version, the screen works very well in this configuration, almost seeming like a giant scope. You can see the wireless version and hear their aspirations for projector based models after the break. [youtube=http://www.youtube.com/watch?v=cnGSpAZtm38&feature=player_embedded]

Homemade Toroid Winder

[ "coil", "controller", "electronics", "parts", "toroid" ]
https://hackaday.com/wp-…r_1721.jpg?w=800
[eclipsed78], built an automatic toroid winder ( Internet Archive ). The drum splits in order to load the toroid. Then wire is wound on the drum, much like any other coil would be wound. The drum rotates as a slider pulls the wire off the drum, while revolving in and out of the toroid. A side tension keeps the slack out of the wire during operation. The winding coil is stepped as the drum rotates, in order to control the turns ratio. [eclipsed78] created a stepper driver from a schematic, so he could drive the motors. You can watch the winder in operation as a series of videos . The first of which is embedded below. If you have ever needed to wind a massive toroidal transformer, this is the project for you. http://www.youtube.com/watch?v=ScfnMcMun-c

When most people encounter dead pixels on an LCD text display, they figure that the display is dead and they decide to scrap it. However when the LCD display on one of [Joe]’s cordless phones started to show dead rows and columns of pixels, [Joe] decided that he could fix it. With only a pencil eraser, a hot air gun, and a screwdriver (for disassembly), [Joe] was able to fix his phone’s screen in just under 10 minutes. His process involves heating the glue holding the LCD’s ribbon cable to the phones PCB with a hot air gun and using a pencil eraser to reattach segments of the ribbon cable to the PCB. If anyone here has a problem similar to [Joe]’s, be sure to check out his detailed how-to complete with step-by-step pictures.

Meaning you will have limited tono success functionally re-plasticizing it viaheat. Even if you do succeed to soften theadhesive of the defective connection you’llalso be doing so to the adjacent connectionsas well given the broad stroke of the heatgun being used.The principle by which anisotropic conductiveheat seal adhesives function is to create anelectrical connection between surfaces viamicroscopic conductive particles embedded inthe adhesive base. These conductive particlesare either fully metallic or metal platedglass/plastic forced into conduction betweensurfaces under tension established by heatset of the adhesive while the joint is heldunder pressure. This is usually accomplishedduring manufacture via a resilient hot barfusing device which holds the entire jointunder pressure until the adhesive has set.By reheating such a broad area there is riskof relaxing unintended adjacent conductors aswell causing them to fail. While the abovetechnique may well succeed in some limitedscenarios, it can as easily do more damage thangood. Particularly given the low mass of theflex cable and the unregulated output of theheat gun.The typically recommended technique to repair adefective heat seal connection is to heat thejoint and remove the entire flex conductor,solvent remove the remaining adhesive on themating glass/flex surfaces, apply a new filmof anisotropic adhesive, *accurately* realignthe surfaces, tack them in place temporarily(a modest temp soldering iron will do here) andre-weld the joint with the above hot barmechanism.That said, if the household hot bar fuser isn’tavailable I’d recommend trying more localizedheat + pressure to repair the failed connection.I’d avoid the use of hot air altogether as itis difficult to control where the heat is beingapplied in this case. Rather I’d place a smallmetallic object such as a bare metal thumbtackhead-down over the suspect joint ideallyseparated from the flex cable by a scrap ofpaper. Heat the exposed underside of the tackwith moderate heat from a soldering pencil andkeep the tack moving and pressed against theflex. Initially the adhesive thermosets is the150*C ballpark so you don’t want to exceed thisby too much otherwise the risk of degrading (oroutright melting) of the flex cable exists.Once the tack is up to temperature I’d removethe heat and keep the tack in pressure and motionover the joint.

[youtube=http://www.youtube.com/watch?v=Pwq6vRM8U7k] Reader, [Matthias_H], sent in a video about his USB adapter for SNES game carts. All you have to do is plug in the SNES game cartridge and USB cable, then a ROM file of the game shows up as an external storage device on your computer. After that, you can play the ROM with your choice of emulator. We emailed [Matthias] asking for more information, and he quickly replied with a very nice writeup about the hack that is pasted below. Update: [Matthias] launched a site for the “snega2usb” with updates on the development of the board and a FAQ. [Matthias] writes: Part list: Atmel AT90USBKey Evaluation Board (Digikey – $30) FCI 10046971-003LF 70-pos. 2-row connector (Digikey – $4.76) a little piece of prototyping board to solder the connector onto thousands of little wires I used the following reference documents: http://www.emulatronia.com/doctec/consolas/snes/sneskart.html (SNES cart pinout and ROM memory map) http://www.microsoft.com/whdc/system/platform/firmware/fatgen.mspx (FAT16/32 specs) The somewhat ugly cable solution is due to the USBKey’s weird choice for .05″ pitch port connectors, for which I was not able to find suitable pin headers and ribbon cable connectors. The exact pinout is a bit weird and not worth publishing yet, since many of the I/O pins are in fact shared by the onboard peripherals, so I have to spread the address and data bits among the available pins. A cleaner version with all parts on a custom PCB is on its way, as well as support for the Sega Genesis (working hard towards the all-in-one solution :-)) Code is based on the Atmel USB Mass Storage example app, to which I added a module for ROM access and a read-only FAT16 (the latter was hard-coded in a hex editor – FUN!). Again, development is still at a very early stage (I tested this on exactly one game cart), and as of now, redistribution of the source is in fact prohibited by Atmel’s proprietary license. I’m not quite satisfied with the data rate yet. As of now, newer-generation console carts (N64 etc), while absolutely possible to read out, would take forever to load. The device is running at USB 2.0 full-speed (12 Mbps), and I am not aware of any cheap solution that offers high-speed USB (480 Mbps). Open issues: – testing with as many different games as possible (feel free to donate your least favorite game carts! :-)) – issuing a refresh when the cartridge is removed/replaced! The USB Mass Storage protocol uses the SCSI command set, so the device cannot send requests (“refresh directory, file may have changed”) to the host. – optimization for speed – add compatibility for HiROM games By the way, I’ve never done anything like this before. The fact that it was so easy kind of scares the hell out of me ;-) I think this is as exhaustive a description as I can give for now. Hope you’re fine with it. -Matthias

Arduino Camera Laser Trigger

[ "Arduino Hacks", "digital cameras hacks", "Laser Hacks" ]
[ "arduino", "camera", "camera trigger", "chdk", "ethernet", "laser", "remote" ]
[Adam] made a remote camera trigger that uses a laser . He had to install CHDK on his camera, which we’ve featured in a how-to , in order for it to work. CHDK allowed for a remote shutter trigger through the USB port. The laser bounces off a mirror and onto the photoresisitor hooked up to an Arduino. When the beam is broken, the Arduino sets off the trigger. He also plans to use the trigger to tweet over ethernet. Embedded is a video demonstrating its functionality.

Already, both Rapid repair and ifixit have torn down the new iPhone 3G S, and phonewreck has provided some analysis . The new CPU runs twice as fast at 600 MHz and supports 720p video. They also found that the new 3 megapixel camera took better photos. Surprisingly, despite apple’s claims that the new phone has significantly better battery life, the battery itself has only 6% more capacity. Overall, not much has changed.

[ross], a reader is working on a CD changing and ripping robot . The arm picks up a CD and the platform then rotates, stopping in front of the tray to drop the CD. A JB welded tire pump provides the vacuum pick up, while a brake light acts as a resistor to trick a PC power supply into operation. A Motor Shield beefs up an Arduino in order to drive the servos.

Meat Thermometer Using Predictive Filtering

[ "home hacks", "Misc Hacks" ]
[ "atmega", "ATmega168", "AVR", "diy", "filtering", "LM34", "microcontroller", "nerdkits", "predictive", "pygame", "python", "thermometer" ]
The guys over at NerdKits put together a really informative video on a meat thermometer using predictive filtering which is viewable below. The video, supplemental text, and code is available on their website. The thermometer is constructed of a LM34 temperature sensor attached to a piece of 12 gauge solid copper wire. The thermometer signal is processed on an ATmega168 microcontroller and visualized using the pygame library for python. The real gem in this project is their excellent explanation of predictive filtering, which could easily be utilized for a large number of projects.

Addressable RGB LED Strip

[ "Arduino Hacks", "LED Hacks" ]
[ "arduino", "HL1606", "led", "lighting", "lightstrip", "rgb", "serial", "synaptic labs" ]
[Synoptic Labs] stumbled upon an RGB light strip with individually-controllable LEDs . The strip uses 5 volts and is controlled by an HL1606. Because the strips are hard to find, this chip is mostly undocumented and he had trouble driving the strip. He was unable to get it working until he met with [John Cohn], who had previously reverse-engineered the serial protocol. Working together, they released a library for the Arduino to drive the strip. So far, the library only supports fading each LED, the only known functionality. If more strips like these were available, constructing LED matrices would be much easier. Embedded below is a video of the strip fading through the rainbow. [youtube http://www.youtube.com/watch?v=ydVPq7UGVZc%5D [Related: LED ambient light strips ]

Slowloris HTTP Denial Of Service
Zach Banks
[ "Misc Hacks", "Security Hacks" ]
[ "apache", "dos", "HTTP", "perl", "rsnake", "servers", "slowloris", "web" ]
[RSnake] has developed a denial of service technique that can take down servers more effectively. Traditionally, performing a denial of service attack entailed sending thousands of requests to a server, these requests needlessly tie up resources until the server fails. This repetitive attack requires the requests to happen in quick succession, and is usually a distributed effort. However, [RSnake]’s new technique has a client open several HTTP sessions and keeps them open for as long as possible. Most servers are configured to handle only a set number of connections; the infinite sessions prevent legitimate requests from being handled, shutting down the site. This vulnerability is present on webservers that use threading, such as Apache. A positive side effect of the hack is that the server does not crash, only the HTTP server is affected. His example perl implementation, slowloris , is able to take down an average website using only one computer. Once the attack stops, the website will come back online immediately. Update: Reader [Motoma] sent in a python implementation of slowloris called pyloris [photo: cutebreak ]

Run slowloris (or similar) and tail your logs.Don’t see anything? Interesting, huh?The reason this works isn’t because the client is “taking up a bunch of sockets”, it’s because the client is beginning a (thousand or more) conversation(s)– actually more like beginning a word in a conversation– then stopping. Apache doesn’t know what to do whatsoever because it hasn’t even heard a word yet. Timeouts are worthless because the script (if the person running the script spent a bit of time finding the target server’s running config) will be run to spawn new processes before the timeout is reached.

Ekahau HeatMapper Maps Out WiFi Signals

[ "autodesk dragonfly", "ekahau", "heatmapper", "map", "wardriving", "warwalking", "wifi", "wireless" ]
The term ‘warwalking’ isn’t used very often, but the Ekahau HeatMapper adds a new tool to the pod bound hacker’s arsenal . The tool maps out wireless access points as well as their signal strength within a facility. A test of the HeatMapper on a map made with AutoDesk Dragonfly accurately determined the location of a router within 3 feet and helped tune the angle it needed to be at for maximum range. Ekahau made a fantastically cheesy promotional video for their product, which is viewable after the jump. The program is free of charge, but unfortunately only runs on windows, so mac and *nix users are out of luck, though it might run under wine.

[sprite_tm], whose projects we have covered in the past , took the popular bristlebot to an extreme and created a controllable version . A bristlebot consists of a small vibrating motor mounted with a battery on the head of a toothbrush. These micro-robots buzz around randomly, and he attempted to tame them. He used a platform of twin bristlebots and added an optical sensor from a laser mouse and an ATtiny13. The optical sensor is used to determine the relative motion of the robot, so that the motors can be adjusted accordingly. He also has a video of the bot using the sensor to find a mark on the floor and stay within bounds. Although it isn’t as accurate, it acts like a traditional line-following robot. [thanks sprite_tm]

Arduino Experimentation Kit

[ "Arduino Hacks", "News" ]
[ "arduino", "breadboard", "kits", "led", "microcontroller", "oomlout", "servo", "tutorial" ]
[Oomlout] has created an Arduino Experimentation Kit that uses basic sensors, buttons, and LEDs to teach electronics and programming. Printed overlays are secured on a breadboard, indicating components and connections. The Arduino is then used to drive the circuit. Examples include driving motors, using shift registers, and making beeps with a piezo element. These are backed up by explanations and code. The breadboarding kit is very similar to the classic 300-in-1 project kits marketed to beginners. In addition, all of the materials are released as open source . Kits are also available that include everything needed to create the circuits. Related: Opensource Robotic Arm [via Hack a Day flickr pool ]

A friend recently commissioned us to install OSX on a netbook. We advised him to purchase the Dell Vostro A90. It’s essentially a rebadged Dell Mini 9, a model that has been discontinued, but is well suited for OSX . It’s only available with a 1.6GHz Atom processor, 1GB RAM, and 16GB SSD. Depending on what deals are available, it’s $250-$300. We also had him purchase a 2GB stick of RAM which is the upper limit supported by the BIOS. Having read Gizmodo’s guide earlier, we knew that process would not be too difficult. The install has actually gotten even easier in the last few months. We followed the DellEFI guide hosted on mechdrew without many problems. The only equipment we needed was a retail Leopard disk, a Mac, and our trusty USB/SATA adapter attached to an old 120GB laptop drive. We copied our image of a legitimate 10.5.6 retail disk to the harddrive and then used DellEFIBootMaker to make it bootable. We copied the DellEFI 1.2a5 program and the 10.5.7 cumulative update to the drive as well. With this, the drive had everything we needed to complete the install. Plugging the drive into the Vostro A90 we dropped into the BIOS setup to turn on USB legacy support so we could boot the drive. We found that we’d often have to go to BIOS first, then exit in order to give the drive time to spin up and appear in the boot menu. After partitioning the laptop drive, the installation is identical to any other Leopard install. The process froze on us on two separate occasions before we got a complete install. It was just a matter of try, try again to get it to work. We think it may have been the fault of the drive we were using. After that completed, we were able to boot our brand new OSX machine and install the 10.5.7 update. We used DellEFI to install the permanent bootloader. Everything seems to work fine and it’s a lovely little machine. We highly recommend the DellEFI single USB drive method which was Version 3.02 at time of writing.

The last of the Commodore 64’s shortcomings has been addressed; it finally has a Twitter client . [Johan Van den Brande] wrote BREADBOX64 for use on the C64/128. It’s running on top of the open source Contiki operating system. The hardware is an MMC Replay cartridge with an ethernet adapter. If you don’t have the hardware available, you can run it inside an emulator like VICE . Embedded below is a C128D running the program.

[youtube=http://www.youtube.com/watch?v=YnZeI8uLJnw] In the video above, [conquerearth] is using a theremin to control Super Mario Bros. Moving his hand toward and away from the vertical antenna increases the theremin’s pitch. The computer monitors this in real time and moves Mario left and right. The loop antenna controls the theremin’s volume and acts as the jump button. The controls seem to work well, much better than the sound of one man flailing at a theremin. [via Gizmodo ]

[Hazard] wanted a full color POV display for his bike wheel. Adafruit’s SpokePOV is single color and Monkeylectric’s original version didn’t display images. He also balked at the cost and decided to manufacture his own version. It uses 16 RGB LEDs on a single layer board he manufactured himself. It’s an entirely through-hole design to make assembly easy. It uses a hall effect sensor to synchronize the image display. The two main components are an ATmega328p microcontroller, which should make it Arduino compatible, and a TLC5940 PWM LED driver. It’s a very well documented build and certainly a good looking effect. [via adafruit ]

Atari Wallets

[ "atari", "cartridge", "wallet" ]
[youtube=http://www.youtube.com/watch?v=fbpq8NEWxYc] [niles] has refined the art of making wallets out of game cartridges . Specifically, he is using Atari cartridges. He’s gotten down to about a two hour process which results in a decently usable wallet. We’ve seen someone make a cartridge wallet before, and we have to ask the same question; who wants to carry this around in their pocket? [thanks yuppicide]

[ "accellerometer", "cell phone", "gesture" ]
[youtube=http://www.youtube.com/watch?v=Nvu2hwMFkMs&feature=player_embedded] Some grad students at Duke University have been working on a new tool for cell phones equipped with accellerometers. The software called  Phonepoint Pen , allows you to write with your phone in the air. Though we don’t find the applications they mention very practical, we could see this being very nice for application navigation. If you could program a 3 dimentional gesture to load certain apps, that would be nice.

[Hazard] is designing this open source POV system for bikes . With the recent release of Monkey Electric’s m464q , [Hazard] was inspired. He found the price tag of roughly $2,000 to be way too much though. He is designing his own and taking us along for the trip. He hasn’t quite reached the Monkey Electric level of features, but he does have image display and simple animation. He encourages others to join him in improving the design. He notes that the image on the back side of the wheel is mirrored, so text would be backwards. Maybe he can pick some tips up from this old project .

[youtube=http://www.youtube.com/watch?v=-b_mE4JhF1o] [Alan] isn’t very good at guitar. He says so himself. He’s not that great at guitar hero either. Was that medium difficulty? Let’s put aside his skill to talk about his controller . He has fused the guitar hero controller with a real guitar. The original guitar has retained its functionality, though the controller bits may get in the way if he jams really hard. With a flip of the switch, it turns into a guitar hero controller. You simply press the strings down at the frets where the buttons should be, while strumming the controller part.

Extra Pleo Battery Pack
Caleb Kraft
[ "Robots Hacks" ]
[ "battery pack", "pleo", "ugobe" ]
Those of you who have played with a Pleo know exactly where this is going. The Pleo averages about 30 minues per 2-3 hour charge. Just swap batteries you say? Nope, the battery packs aren’t available. Fortunately, you can make your own pretty easily .  The basic frame is a standard battery pack for 6 AA’s. There are only a few modifications necessary to line up the leads and make it fit once you’ve loaded it with batteries.
