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.

Orlando's Community Lab / Hackerspace. Solar Charging Handbag. Welcome to the summer of solar!

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. This is a fun soldering project you can build in an afternoon! When you’re out in the sun (or as long as your bag is), the battery charges up. You can simultaneously charge your phone when the sun is bright, and the battery will keep supplying juice long after the sun goes down. Before you begin, read through the following guides: ArduPi Webcam Tankbot. This is my first robot project though I have been working with Microcontrollers and Embedded Linux for a little while.

ArduPi Webcam Tankbot

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 When you have a problem that requires exact control in real time, such as a controller for a 3D printer.

Here are some other ways the Arduino has a leg up: - Supports analog pins required for many types of sensors and actuators - Supports a larger number of digital pins - Includes PWM pins (pulse width modulation) used for some types of sensors and actuators - Some Arduino clones are cheap as fudge - Lots of parts made to integrate directly with Arduino, such as sheilds. 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. It could become a truly independent, intelligent Wall-E robot!

However, building such a robot will be a project for near future. Note: Please be careful about the indentation in the Python codes, sometimes my blog decides to mess this up randomly. I wrote an article on how to use SSH and VNC to control and monitor the Raspberry Pi, and that’s what I will be using in this project. To install OpenCV for Python, all you have to do is use apt-get like below: sudo apt-get install python-opencv You will need to download this trained face file: The idea is simple. 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. It's called an AlaMode, and it goes for something like $50. As a first step, we will build an Arduino plug-in board for the Pi.

We will be using generic stripboard to build our project. Quite a number of Pi projects involve connecting sensors and devicesdirectly to the GPIO pins. This particular project connects directly to the GPIO Rx and Tx pins. This is a moderately complex project, and beginners need not apply. Ready? 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. It also has a few hardware pins that can be used to drive external devices. Now to interface with a micro-controller… The most obvious external “thing” I wanted to hook up was the arduino. You plug the arduino into your usb port, upload some code, and suddenly you’re controlling a motor. Finally, you’ll want to interface the arduino with a computer, because it’s no fun having a microcontroller that can’t interface with the internet. Commmand-line arduino?

The raspberry pi only has 256mb of memory so you’ll probably want to upload your sketches via command-line instead of using their fancy UI. We’re going to use the serial header exposed by the GPIO pins to communicate with our arduino, so we’ll have to remove it’s use on the raspberry pi. 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. On the other hand Arduino™ is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software with tons of available shields to interface with outside world, but again having its own limitation of 8-Bit controller. Both, the Raspberry Pi & Arduino™ platforms, offer some very good functionality and serve different community but with their own limitations. CooCox team came up with a new product named “Embedded Pi”, which integrates and blends all the three communities together; Raspberry Pi, Arduino™ & ARM, and help to exploit the functionality of one platform from the other.

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. Airfoil terminology[edit] Airfoil nomenclature The various terms related to airfoils are defined below:[6] The suction surface (a.k.a. upper surface) is generally associated with higher velocity and lower static pressure.The pressure surface (a.k.a. lower surface) has a comparatively higher static pressure than the suction surface.

The geometry of the airfoil is described with a variety of terms. Thin airfoil theory[edit] where . Engranaje. 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. If an SBC supplier labels their product as “extended temperature”, then it will be reliable in the field. Right?... More. 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. Torque_Old * Velocity_Old = Torque_New * Velocity_New Torque_Old and Velocity_Old can be found simply by looking up the datasheet of your motor. 3 lb-in * 2000rps = Torque_New * 300rps 3 lb-in * 2000rps = 5 lb-in * Velocity_New.

Automaton. Yesterday, Melonee Wise (co-founder and CEO of Unbounded Robotics) gave a talk at Xconomy's Robo Madness event. We were expecting to hear about how things were going with the UBR-1, and maybe some hints as to when it'll be available, but she surprised us by instead talking about PlatformBot, a prototype service robot that was apparently developed at Willow Garage in early 2012 but never released. This was a surprise mostly because we only had a vague idea that anything like this even existed: it was certainly never public, but Wise's presentation made it clear that a huge amount of time and effort had gone in to deciding what PlatformBot was going to be, and then making it a reality.

We have no idea what happened to these robots, except that UBR-1 looks a lot like some of the concepts, which is probably not a coincidence, because the entire Unbounded Team seems to have been closely involved in the PlatformBot project before they spun out of Willow.
