3D printable 'Drone It Yourself' kit turns any object into an UAV Jul.6, 2013 Home-built drones are very popular among hobbyists with backgrounds in electronics and robotics. Jasper van Loenen, an independent designer working in the field of interaction/information, design and art, wanted to make the design simpler so anyone can make their own. Van Loenen has created a custom DIY (Drone It Yourself) v1.0 kit that turns any object into an unmanned aerial vehicle, simply by attaching four motors and a control unit – no technical know-how needed. The plastic parts for this 'Drone it Yourself' project have been 3D printed in ABS. Both the original files and the printable STL files are available here.
Which Programming Languages Can You Use With Arduino? Ready to try something different with your Arduino? You needn’t be confined by programming in C. Take these alternative languages for a test drive. The Arduino IDE is core to the ethos behind the project — it’s a UI that attempts to turn the daunting task of learning a programming language into something that anyone can take a stab at. Just as there are an enormous range of different coding languages, there are a multitude of different reasons that you might want to take a different approach to programming. The important thing is to find a language that speaks to you and the goals that you’re looking to achieve. ArduBlock Arduino is built around a straightforward programming language that’s meant to be welcoming to newcomers — but if you’re really short on experience, it might be worth trying a tool like ArduBlock. It’s great for younger users, but don’t think that this is ‘Arduino for Kids’. ArduBlock is a downloadable tool that runs as an overlay to the official Arduino IDE. Python
High-Range Wireless Power How we simulated the design We simulated and optimized the design in a 2-D mangetostatic simulator, and with SPICE. We used the free 2-D mangetostatic simulator called Infolytica. You can download for free here: We used the free SPICE simulator called LTSPICE. Design files for both simulators are attached. Discussion This design uses resonant magnetostatic power transmission. We simulated & optimized the coil with Infolytica's 2-D magneto static simulator. Magnetic Simulated Values: Transmitting Coil = 4.35mHReceiving Coil = 0.105mHMutual Inductance = 9.87uH. We then took those numbers and fed them into SPICE to simulate the electrical characteristics. You can download the simulation files attached, and try to make your optimizations and measurements! Also attached are field plots, that show the magnetic field produced by the coils.

Introduction to hobbyist Lock picking Aka: LockSport - All Lock picking gets a bad wrap. When most people hear the phrase, it congers images of illicit activities and unscrupulous personas. But really, when it comes to petty larceny the most effective strategy isn't going to be lock picking. Destructive entry: bricks, angle-gringers, bolt cutters and sledgehammers are the order of the day. The information to follow will strictly pertain to the budding hobbyist/enthusiast: how to get into "Lock-sport," as logically and cost-effectivly as possible. It's important to note, prior to any purchases, the rules and regulations of whatever state/province in which you happen to reside, and to know that lock-picking carries with it a stigma, which could put you in an uncomfortable situation should something go missing in your school or place of work, as such, discretion is recommended, and even more so, DON'T GO BREAKING THE LAW!!! Hope you enjoy, Cheers. PS: I've included a short glossary of terms in the final step in this instructable just in case.
Understanding TRRS and Audio Jacks - Cable Chick Blog Learn about the varieties of audio jack and how to identify them, plus discover why one TRRS cable won't work for all your AV needs. We know them. We love them. They've been around since before the first Walkman and they'll stay for a long time to come. Over the years, the general public have come to refer to both the male and female of the species as an 'Audio Jack', even though this is not technically correct. To keep things easy, we'll use the term plug for male and socket for female whenever we need to be specific, and we'll pretend jack is genderless. Once upon a time, what we now see as stereo jacks or headphone sockets were used in the telephone switchboards of the 19th century. T = Tip, R = Ring, S = Sleeve These days it's generally easier and more accurate to refer to each type by their Tip/Ring/Sleeve configuration to avoid any misunderstanding, especially when balanced audio is taken into account. Why move the ground contact?
Learn Electronics and Arduino Just By Watching These Videos Advertisement Learning to program your own electronics is empowering and rewarding, but it can be difficult to get started without guidance. We’ve rounded up the best videos, YouTube channels and online courses to get going. What is Arduino? Arduino is a popular open-source microcontroller, meaning a small computer with programmable inputs and outputs. Still not sure if you want one? I was lucky to have a professor in university teach a course on programming in Arduino. YouTube Channels about Arduino Tutorials for Arduino by Jeremy Blum Typical video length: 15 to 30 minutes. Jeremy Blum has been educating people on how to use Arduino for years now.

Over at EEAwesome, Professor Rudy Schlaf has a series of videos on basic Arduino concepts. Arduino Video Tutorial by Arduino Typical video length: 5 to 15 minutes.
Electronics made easy Resistors are simple: they limit the amount of current allowed through a circuit. Resistors are color coded to make it easier, and can have four, five, or six colored bands. Resistors are measured in Ohms. To find the resistance of the four-band resistor: look at the resistor, make sure the side that has a silver or gold is to the right (there might not be a band with one of these colors, make sure the side that has no band is to the right). now you simply read it. write down the first value write down the second value the third number tells you how many 0's to add to the number the fourth number tells you the tolerance. black=0 brown=1 red=2 orange=3 yellow=4 green=5 blue=6 Purple=7 gray=8 white=9 Silver=10% tolerance Gold=5% tolerance In the picture the resistor is red green red gold, so that would be 2500-5%.
Cheap precision drill stand - All I came at this solution after taking care at cost (if your DIY is very expensive it's better you buy it!), efforts (all my hardest project are still waiting to be completed), parts availability (if you have to wait shipment for each part of the design you'll forget for how you needed them, especially with Italian post service) and functionality. The slide is a "macro rail" for photography which you can find on eBay at about 10$, but I already had a couple of them.

Laser Etching Glass This tutorial tracks my process of using various software programs and a laser etching machine, glass acid etch and glue with a base plate of LEDs to make the glass sculpture. The sheets of 6mm float glass has been hand cut and laser etched twice (both sides) to preserve the resolution of the data. Below is a glass cutting video, showing the technique of hand cutting. The final size of the glass work is 300mm w X 600mm h x 258mm d - weighing about 70kg The sheets are glued together and footprint of LEDs below light the laser etching of the glass. The scope of this tutorial is to address digitally handling data, using a laser cutter with glass, glass etching and gluing for an artistic application. This project I used: A 100w laser cutting machine Below is a link to a very cheap laser cutter by darklylabs Float glass 6mm thick - see image above Glass cleaning products, paper towels 3d scan data to do slicing which is free :D
Overview of Quadcopter Components / How to Select Parts - All Quadcopter frames come in a large variety of layouts, sizes, and materials. The 2 main layouts are: 1. If you plan on doing acrobatic maneuvers such as flips and/or First Person View (FPV) flying, a racing frame would be your first choice. The size of the frame will usually be denoted by a number such as 150, 200, 450, etc. Some materials used in quadcopter frames include: 1. Material selection is largely based on how much you want to spend on a frame. Additional parts to make mounting components easier are shown above (links in the picture notes).

Four ways to power up the Arduino Uno The Arduino Uno has undergone many revisions and hence the power supply circuit has evolved to an almost foolproof design. In this project we will learn about the four different ways in which we can power up the Arduino Uno. While making projects it is necessary to know the following techniques, since there are instances when flexibility with regards to the power supply is required. Things required to power up the Arduino Uno We are going to need the following apparatus to learn how to switch on the Arduino Uno. An Arduino Uno board (Rev 3)Standard A-B USB cableAC to DC Adapter (7-12V)Batteries (9V) with a battery connectorJumper wires (Female to Male) Images (Things required) What is the procedure to power up the Arduino Uno?
