How to build your own USB Keylogger Cause I've searched a lot for a project like this, and I haven't find anything around the Web, I would share my experience of my personal USB Keylogger. It's not really a pure "USB" Keylogger (cause USB HID protocol is much more difficult than PS/2 protocol), but it adapt an USB Keyboard to PS/2 port, while (of course) recording the keys pressed. In this way, even if it's discovered by anybody, it should be confused with a normal PS/2 Adapter. That's the final result: It need just a few component (SOIC PIC and EEPROM can be freely ordered as a sample from ): -PIC 12F1822 (SOIC Version) -EEPROM 24XX1025 (Any 1Mb version will be ok) (SOIC Version) -2 * 4k7 Resistor 1/8 W (Or any resistor of the same value as small as you can solder in the adaptor) -Pickit 2 / 3 (For programming the pic and reading the eeprom) -An USB to PS/2 Adapter that can be opened. And, very important: -A GOOD solder and VERY GOOD soldering abilities. Let's Start. Regards, Jamby

• Page d'index Open Circuits PingBot : Un petit robot amusant simple à réaliser PingBot est un petit robot tout droit sorti de l’imagination de Tomdf, il a été conçu avec l’esprit d’ être le plus amusant possible tout en conservant une simplicité extrême. On peut dire que le pari est réussi. Au niveau de la partie électronique, on retrouve principalement un micro-contrôleur Picaxe 08M2 qui permet de piloter chacun des éléments. On retrouve d’ailleurs : 2 moteurs permettant de réaliser le déplacement du robot.2 LED pour éclairer les yeux et lui donner un peu plus de personnalité.Un LED de réception infrarouge pour pouvoir le piloter avec un simple télécommande.Un buzzer piezo pour lui permettre de jouer des sonsUne prise de programmation et de recharge micro USB Pour alimenter le tout, on retrouve également une batterie Lithium Polymère de 3.6V et un mAX1555 pour réaliser le circuit de charge. La coque a été réalisé avec une imprimante 3D et peint à la main pour donner encore plus de personnalité à ce robot PingBot. Voici une vidéo de démonstration de PingBot.

OneDarwin < Main < Reprap Overview RepRap 1.0 "Darwin" is a rapid prototyping machine that is capable of making the majority of its own component parts. Instructions and all necessary data are available completely free under the GNU General Public Licence from this website to everyone. As RepRap 1.0 "Darwin" can copy itself, once you have one you can make others for your friends; or if they have one you can ask them to make one for you. Of course, you can also make as many as you want for yourself; the more you have, the faster you will be able to make other items. Darwin consists of a frame made from rods and printed parts. Specification The RepRap 1.0 "Darwin" machine has the following characteristics: Bill of Materials (BoM) The Get a RepRap kit page will give you several options on how to get hold of the bits you need.

Les sculptures électroniques en forme d’insectes de Luca di Filippo Les composants électroniques ne sont pas seulement dédiés pour réaliser des circuits, Luca di Filippo le sait bien et il nous montre son art en les détournant de leur usage initial. Bien plus qu’une sculpture électronique, les petits insectes qu’il réalise véhiculent également un message. L’électronique est tellement omniprésente dans notre quotidien que nous ne la remarquons même plus, un peu comme la plupart des insectes qui envahissent les recoins les plus sombres de votre maison ou votre appartement. Voici donc quelques photos pour découvrir ces bêtes de silicium. optiplex G260 drivers Yes We were unable to verify the Service Tag or Express Service Code you have entered.

Eastern Geek: Iron Man Inspired Repulsor Beam Blaster V1.0 Homebrew repulsor beam blaster that’s designed to produce extremely intense burst of light that can be used to repulse your archnemesis, girlfriend /wife and pet cat. WARNING: The build involves high voltage and intense light so please take the necessary precautions. And please be warned that , walking around with one of this strapped to your hand may seriously jeopardize your chances with the opposite sex. Assembly The repulsor is essentially two circuits that are switched ON/OFF using a DPST switch. The source of the DC Step-up Charging Module is the good old analog cameras. The function of this circuit is to gradually step up the 3V source up until 330V, and releasing the stored charges very rapidly when triggered. Do not short the lead of a charged capacitor, it will pop in your face, literally. The purpose of the discharge switch in the schematic is to short and safely discharge the capacitor when it’s no longer in use. Assembling The Lamp The lamp reflector is a bit tricky to source.

Make a gorgeous Dragon's Egg First of course you have to buy your egg (or raid the fridge). I used large hen's eggs for this project (keeping it easy), but you could use duck, goose or even ostrich if you are feeling really adventurous. The beauty of the hen's egg is that the glue gun hotmelt really works at this scale. Please use free range if you can... help chickens have a better life. So, first off, wash the egg quickly in cold, slightly soapy water. Now, to making the hole; strangely, this is not as easy as it sounds. To make the hole you get a very sharp craft knife. Once you break through the going gets easier, but you still have to take care as the blade can bite in and chip or crack the egg. Make a hole like this IN BOTH ENDS.

DIY BioPrinter We started out by messing around with an old inkjet printer that we literally saved from a sidewalk somewhere. There's already plenty of interesting things you can do with an low-end off-the-shelf inkjet printer, but they do have some limitations, which we'll get into in the next Step (or skip straight to Step 3 for how we built our own bioprinter from scratch, that you can see in the first picture above). Undressing the Printer We disassembled an abandoned HP 5150 inkjet printer for use as a bioprinter. Just rip off all the plastic covers you can find, but make sure you can still operate the reset buttons etc. on the front panel. There's a little momentary switch that senses whether the cover is open. There's also a momentary switch inside the paper handling mechanism that senses whether paper has been loaded. Once you've got your printer all undressed, and figured out how to activate the cover-closed switch - print something! Cartridges Prep Filling the Cartridges

DVD Laser « Transmissions from Planet Stephanie The laser pictured above has a peak output measured at 225 mW (average output 200 mW). It’s a visible red at about 650nm. It can light matches, pop balloons, cut electrical tape, and so forth. It can do pretty much anything a Pulsar 150 from Wicked Lasers can do, because it’s basically the same thing. So, how did I do it? Warning: This information is provided for entertainment purposes only. Step By Step Step 1: Get a Laser Diode DVD-RW drives are quite common today. This is the DVD drive I bought for $39.99 (Canadian), for the express purpose of tearing it apart for a laser diode: Once I had the DVD drive, it took me less than 15 minutes to completely strip it and extract the optical works. Step 2: Test the Laser Diode Once you have the diode out, you need to figure out how to make it go, if it’s visible or not, and if it’s got enough power to make it worth your while. The laser diodes I’m familiar with look like this: They may not look exactly like that, though. Presto! Summary Play Safe!

Pingbot - Micro RC Rechargable Musical Robot Pal Pingbot is a very small (38mm diameter), usb rechargeable, programmable, musical, remote control robot designed for maximum fun and danceability. I've built a few experimental robots in the past and, to be honest, they all looked the part. They were nothing more than circuit boards with wheels glued on.They did help me learn, but they just didn't feel like completed robots. In this Instructable I will share what I've learned while creating the Pingbot. Included are schematics, a PCB layout, PICAXE code, 123D model files and pictures of the construction process. Update MSurguy, a friend I made through this instructable, has finished his own version of the robot.
