ArduinoPhone. At the very beginning, we’d better prepare the materials. Of course, most of these modules can be purchased directly, such as Arduino Uno, TFT Touch Shield and GPRS Shield. Owning to we want to put our Arduino Phone into a 3D printed shell, and in order to adapt the size of this shell, we have to DIY a charging and discharging PCB board (including two parts) and an expansion PCB board which can connect to the headphone jack of GPRS Shield. If you want to make a shell by yourself, you can directly take Lipo Rider, or something like this, as the charge sheet. Thus, you do not need to DIY PCB board in order to meet the size of the shell.

How to make the Ring Lamp. DIY Electronics. Limor. 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.
Build a Paper RoboBee Model. Brushless Gimbal for Aerial Photography Drones. Every self-respecting drone used for aerial photography needs a gimbal. Good gimbals are very expensive, cheap ones are not smooth. Brussless Gimbals (BLG) to the rescue! In there recent months there has been a flurry of activity around this new way of building camera gimbals. Instead of servo motors, a BLG uses re-wound Brushless RC motors in a direct drive configuration.
The cheapest of all BLGs on the market today (and readily available) is the GoPro BLG and Controller (Martinez v1) from RcTimer. Testing of finished gimbal: Timelapse video of the build: Mechanical Iris Greeting Card. 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. Deux techniques permettant de faire sauter en l’air des micro-robots. Fabriquer un petit cube GPS à base d’Arduino. 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. The main purpose of this project was to combine electronics and 3D fabrication into a robot complete in both form and function. A fun robot with a sleek look and a bit of personality.
The second goal was to make the robot as small as possible, smaller than half a ping-pong ball (hence the name). In this Instructable I will share what I've learned while creating the Pingbot. Included is information about PICAXE Micro-controllers, surface mount soldering, PCB design, Autodesk's 123D 3D design software and 3D fabrication, rechargeable lithium-polymer batteries, as well as a few painting techniques. Comment construire un laser (guide général) Here you have 2 options: either to get a DVD drive for pc and extract only the diode assembly (aka sled). or buy just the laser assembly from the internet. You can get old DVD RW drives on ebay for >15usd, or just look around and ask friends if they don't have some old unused drives. The another option is to buy just the sled ftom internet. My favourite e-shops for laser components: on these sites search for LPC-815, this is the most commonly used red laser (22x write speed). What if I can't find the LPC-815, if I have only 20x or 16x burner, or if I'm not able to determine the write speed?
You must extract the diode from the sled. If you have other model of dvd burner, set your DMM to the DIODE TEST mode and test both diodes using the pinout below. 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. If you go up in size, then you have to be prepared to do a lot more work to get the egg to look right. Please use free range if you can... help chickens have a better life. Don't worry about the waste, There doesn't have to be any. Once you have blown the eggs, you can always make scramble or an omelet from the contents of the egg. 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. 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. The only differences? 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. Project #R³bots : Des sculptures de robots réalisés avec des élements électroniques recyclés. Marco Fernandes est un artiste qui réalise de magnifiques sculptures de robots avec des pièces recyclées en provenance de divers appareils électroniques. Voici quelques photos pour découvrir ces oeuvres d’arts numériques. Et voici une vidéo nous montrant la réalisation d’un robot : 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. SEMAGEEK : Actualités High Tech, Robot, Électronique, DIY et Arduino. Le bras mécanique d’Iron Man recréé, avec laser fonctionnel. Touch Activated Finger Led (Glove Optional) LED series parallel array wizard. 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. 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.
