Make Conductive Ink

Now you can DIY that part, too! Jordan Bunker of Pumping Station: One in Chicago embarked on this chemistry project and documented the UIUC process into easy-to-follow instructions. Conductive inks have a myriad of different interesting applications. As a quick, additive construction method for electronic circuits, they are especially intriguing. As with most things worth doing, there are risks. NOTE: Please don’t do this at home unless you understand the risks and dangers and know how to avoid them. See the material list, full process, and trial and error on Jordan’s post.

Solar Charging Handbag

Why not soak up some free power from the sun? Charge your gadgets on the go by making your own solar battery charger, then affix it to your favorite handbag or backpack. ArduPi Webcam Tankbot. This is my first robot project though I have been working with Microcontrollers and Embedded Linux for a little while. As of writing (3/1/13) this is still very much a work in progress, but most of the hardware construction has been completed.

This robot will provide a remotely controlled, mobile platform for a pan/tilt webcam. It is based on the excellent Tamiya Tracked Chassis Kit with the Dual DC Motors connected to the Arduino Motor Shield R3 via the Screw Terminal. The Pan/Tilt function is provided by two Tinkerkit Servos which also allows them to be connected to the Motor Shield without taking up additional pins. The webcam is connected via USB to the Raspberry Pi and streamed to an online server using MJPG-Streamer and an Edimax wifi dongle. Carriots.


Aplique hiedra espiral. Raspberry Pi + Arduino - niltoid.niltoid. The Raspberry Pi kind of looks like an Arduino replacement as far as it’s physical appearance.

Raspberry Pi + Arduino - niltoid.niltoid.

At first glance, it’s specs are much more impressive for the same price point as an Arduino. However, it is by no means an “Arduino killer”. You could certainly swap out one for the other in some simple use cases. However the two devices have very different capabilities, and I find that they actually complement each other quite well when combined. Pictured here left to right: Raspberry Pi, Arduino Mega, Arduino NG, Arduino Pro Mini. WiringPi. Raspberry Pi Face Recognition Using OpenCV. About a year ago, I created a Wall-E robot that does object and face recognition.

Raspberry Pi Face Recognition Using OpenCV

It uses Arduino as the controller and need to communicate with a computer that runs the face detection program to track the target. Raspberry Pi face recognition has become very popular recently. With the powerful processor on Raspberry Pi, I can connect it with the Arduino using i2c on the robot and run the object recognition program on-board. The Raspberry Pi - Arduino Connection. The Pi is a fine little computer board, though not nearly as good as the Arduino when it comes to I/O capabilities.

The Raspberry Pi - Arduino Connection

The beautifully-engineeredGertboard is a plug-in add-on that neatly overcomes this deficiency by giving the Pi access to an ATMega328, but it's a very complex and expensive solution. An alternative would be to interface an Arduino running at 3.3 volts to the Pi, though this is easier said than done. But, we won't let that stop us, will we? You can buy a prebuilt commercial version of something similar to this project. Arduino and the Raspberry Pi. I got a PI!

Arduino and the Raspberry Pi

So I got a raspberry pi. It took almost 10 weeks to arrive, but it was definitely worth the wait. For those who don’t know, the Raspberry Pi is a cheap $35 computer that includes processor, memory, and a sd card slot for the hard drive. Embedded Pi. Why do we launch Embedded Pi?

Embedded Pi

It was a year ago when Raspberry Pi was launched in UK, received huge coverage worldwide. However, it has its own limitation to interact with outside environment. Raspberry Pi to Arduino shields connection bridge. Article Index Go to Index1.

Adafruit Learning System. DIY Drones. Airfoil. Examples of airfoils in nature and within various vehicles. Though not strictly an airfoil, the dolphin fin obeys the same principles in a different fluid medium. Introduction[edit] Streamlines around a NACA 0012 airfoil at moderate angle of attack Lift and Drag curves for a typical airfoil Supersonic airfoils are much more angular in shape and can have a very sharp leading edge, which is very sensitive to angle of attack.

A laminar flow wing has a maximum thickness in the middle camber line. Schemes have been devised to define airfoils — an example is the NACA system. Engranaje. La principal ventaja que tienen las transmisiones por engranaje respecto de la transmisión por poleas es que no patinan como las poleas, con lo que se obtiene exactitud en la relación de transmisión.

How to Build a Robot Tutorial - Society of Robots. Learning Resources. When integrating Single Board Computers (SBCs) into industrial, military, and aerospace systems, engineers typically specify an extended temperature range SBC for their embedded computing requirements. The “extended temperature” designation theoretically assures that the SBC will perform reliably in extreme temperature environments. How to Build a Robot Tutorial - Society of Robots. Introduction to Gears No good robot can ever be built without gears. As such, a good understanding of how gears affect parameters such as torque and velocity are very important. In this tutorial I will first talk about the basics of gears, how to use them properly along with simple equations, and then I will go into specific types of gears.

Mechanical Advantage, Torque vs. Rotational Velocity Gears work on the principle of mechanical advantage. This means that by using different gear diameters, you can exchange between rotational (or translation) velocity and torque. As with all motors, by looking at the motor datasheet you can determine the output velocity and torque of your motor. With gears, you will exchange the high velocity with a better torque.


Automaton. Star Wars fans will no doubt remember the pod-race scene from Episode I: The Phantom Menace, where the young Anakin Skywalker speeds through a barren landscape in a jet-propelled, levitating scooter, ultimately edging out the competition. Teenage thrill seekers are not yet able to dash through the air quite like that, but a similar adrenaline rush is now available to almost anyone through the new sport of drone racing, which typically involves radio-controlled quadcopters zooming around a predefined course low to the ground.

The buzzing contraptions are piloted by people with sharp reflexes through video goggles or some other means of obtaining a first-person view, a form of radio-control model flight that goes, naturally enough, by the acronym FPV. Multiple drone-racing leagues have sprung up in the United States, and this summer saw the first Drone Nationals (more properly, the 2015 Fat Shark U.S. The attraction of drone racing is easy enough to understand. Maxwell's wheel pendulum. Maxwell's wheel is the classic way of showing the interplay between potential energy and kinetic energy, along with the effects of nearly-elastic collisions.

Para votar este post conéctate con Facebook ¿Qué hacer con el aceite usado de las comidas?

Tras esa pregunta, una estudiante de la Universidad CEU-Cardenal Herrera de Valencia llamada Analía Blanco tuvo una idea clara: fabricar jabón como se había hecho tradicionalmente, pero con una máquina que ayudara a los interesados en ahorrar reciclando. Y se puso manos a la obra, claro. Tras dos años de trabajo, pudo presentar un prototipo de pequeño electrodoméstico que facilita la fabricación del jabón. ¿El nombre del curioso aparato? Considerando la responsabilidad medioambiental que nos corresponde como ciudadanos, tenemos que cada litro de aceite que se vierte por un sumidero contamina unos 1.000 litros de agua.
